Positive Money is really about trying to change the financial system so that it works for society and not against it. We have groups around the country and also another 15 groups internationally, sister organisations. Other people helping out, volunteers, contractors and all of the local groups and the international groups who all give their time for free. So really quite a big base of people who are trying to make this happen. What we have today is that all money that we use is created by banks, high street banks when they lend and what that means is that we have a money system that is based on debt so if we want more money then we also have to have more debt and that results in a whole series of problems. We're trying to look at the way that money is created by the banking system and the effect that has on debt and poverty, on affordable housing, inequality and the whole range of other social problems that we're facing at the moment. I'm quite passionate about what Positive Money is trying to do because number one, I got caught up in the big party that was going on before 2007. Everyone's investing in property, borrowing too much money. That happened to me and I'm now in a position where I owe far more money than I'd like to and I think looking back I probably shouldn't have borrowed it, I shouldn't have been allowed to so I think that's something flawed in the system. We think this is a big problem and we think that actually the power to create money shouldn't be privately owned money shouldn't be created as debt. I think that actually the power to create money should be returned to the people essentially. The power to create money should be used in the public interest and the people that create money should be the Bank of England and it should be done in a democratically accountable manner and in a transparent manner. I just feel that it's like the common denominator of so many different problems. It's I think one issue that if we could change it it would just automatically resolve so many different problems that we're facing. Today's really about what the individual gets out of it themselves. How much effort they've put in is inevitably how much they've gotten out. That's what I've taken. You find some people who are very pessimistic some people who don't think things are possible and then you find people who are flexible who have a can-do attitude or kind of like oh you know what oh we can't meet on this day maybe we can do this or oh we're all geographically dispersed but hey we can do something about it. I think it's helpful to bring people together to share ideas what's happening across the country to meet new people. I've met a few people today that were very concerned about the issues raised by positive money in my area that I didn't even know existed. I think it's important for a number of reasons. One is to retain that momentum from supporters and perhaps develop new supporters as well to help those understand the principles that don't already and people like me are relatively new to the concepts. I think it's also important to learn lessons from one another and to think about where to go next and to use the broad range of skills and experiences in the room today to do that to the best effect. If only positive money could get over this one idea money where does it come from and then the next point of course is it's our money and shouldn't we decide what's to be done with it. We know it's a huge change that we're trying to achieve but the thing is that we've already got over 22,000 people on board after only going for a few years and with such a radical thing we're proposing that's really exciting. We've got groups in 19 different countries that want to try and change their own money system in their country and we're all fighting for the same cause and we can share and help each other to be able to communicate what we're trying to do. We should be optimistic because firstly things do need to change politicians and the people in charge are running out of ideas and that there's more and more discussion in the press and in policy circles and amongst the general public about these fundamental problems with money and that these change.


Forgive me. Hey, I'm just testing out this on YouTube live Testing out YouTube live Want to pop in I got a question today and Well, I see this question all the time when I'm doing my Instagram Q&A and the question is How do I know if a man is interested and today? I've been hearing a lot, you know in coaching sessions women saying to me Oh, if a man contacts me every day, it's creepy And that always kind of creeps me out because I'm like wouldn't you want to hear from someone every day if They're interested in you or if you're interested in them And so one thing I see a lot is that Because of social media today because of the text message society and because of the dating apps men have a lot more women to Entertain so if a man goes on a dating app, he's meeting five to ten Datable women every single week. So you're talking 20 to 40 dateable women every month and then Because of text message you can text with five to seven to ten different people at one time and so you text a lot and a lot of women today are putting a lot of emphasis on the Hello, beautiful like that good morning text in the morning Which it means nothing because you literally can have a list of ten women Text hello, beautiful Copy it and then just paste it in the next nine messages and you're done in like 20 seconds And then women are taking that and fantasizing and just letting it mean something let me mean all this But I'm gonna tell you the number one key to know that a man is interested in you for the right reasons Truly interested in you for the right reasons is this man will get on the phone with you every single day For at least an hour Now I know some of y'all say look I don't have time to talk to a man for an hour for at least an hour He will get on the phone if that means from 9 p.m. To 10 p.m. 10 p.m. To 11 p.m You know that last conversation before bed or if it means 15 minutes in the morning when you're heading to work 15 minutes at lunch so that you still have some time to eat your lunch in peace 15 minutes after work when you're heading home and 15 minutes at night to say good night However, it breaks down and this isn't you know an exact science But understand that at least an hour a day, okay 45 is about the same thing 30 is still something but truthfully when a man is interested truly interested it's going to be about an hour a day and then If he's really really interested and you have the time Then he will Give you two hours three hours four hours. I've been married 12 years I don't know how the cameras flip, but this my left hand I've been married 12 years and when I met my wife We sat down our first conversation we talked for six hours We sat down the next day on the bench outside of her apartment. We talked another six hours When I was at my apartment and she was at her apartment We would get on the phone every night and talk two three four hours and we would be in person We would be talking like four hours minimum why I was extremely into her and I came from being a womanizer A dog a liar a cheater a manipulator a deceiver. So what I'm saying is if the absolute worst man Worst type of man the biggest player can meet a woman really like that woman and give that type of time and energy then The everyday guy who's not really a womanizer not really promiscuous Then he definitely should be given that type of time and energy And then as a woman if you're like look, I don't want to talk to nobody that much You have to question if you really want to be dating and you got a question Why you got a question if you've dated so many tough guys so many bad boys that call you every other day You know talk just text you Majority of the times in communication He's just texting if you've gone through that so much to where that has become your norm And you've been accustomed to become accustomed to in condition to just getting Mostly text message communication or like five ten minute phone calls You're talking like that you can't even get to know a person text is not real In building a relationship text is not real. It is not real There's too much time to think about what you're gonna say There's too many messages that can just be copy and pasted to every single person text is not real You need to be able to talk to a person on the phone where the conversation is fluid To where they don't have time to think up lies to try to come up with all this game They just got to be able to talk from the heart You can ask questions boom boom boom right on the spot get real time answers And to be honest with you if you live in the same city A lot of these conversations can be in person or you can do it by FaceTime where you can see a person's Facial response you can see what they're saying because today in this dating app society you really want to Take up as much time as the person you're dating As you can without neglecting your priorities Don't neglect your priorities. Don't neglect your job. Don't neglect your children if you have children Is don't neglect your sleep So there should be no neglecting But you should be taking up as much of that free time as you have to get to know someone Because if you're just texting or if you're just talking on the phone every other day every three days You're wasting your time and here's the issue with that when you're not talking consistently and actively The issue with that when you're trying to build a relationship or you're trying to sustain a relationship like my wife and I When I you know, she's cooking for my son. We just got home from soccer practice My five-year-old he's already in bed my 12 year old We just came home so my wife is cooking for him. So they give me some time to come talk to you When he's done eating he's getting in the shower that he's going he has to do some homework Then he's going to bed. Let's say he gets in bed 9 30 Me and my wife we we will sit and talk from 9 30 Probably to 10 30 11 30 sometimes midnight sometimes one two in the morning Why sustaining and building the relationship 12 years into marriage We still try to talk an hour or more every single day Sustaining building the relationship. I got a flight to california tomorrow You know, so when I get in the hotel room if I can get in before she has gone to bed We will talk two hours on the phone Sustaining and building the relationship See what happens when you don't do that is if you talk to somebody on monday And then you just text on tuesday And then you talk on wednesday you just text on thursday What happens is a man has time to fill in other women on those in between days and then also Women what y'all do Is when you talk to a man on monday You will fantasize about him on tuesday And then you'll be fantasizing about this man You're thinking about how nice he is how sweet he is how amazing he is And you're not paying attention to his lack of effort and his lack of attention and his lack of Actions that he's not showing up on a daily basis And you may be okay with it if you've been conditioned or you've been telling yourself That you don't want to talk to a man every day because of your life If that's the case you shouldn't be dating because a man has to talk to his woman every day Just to stay focused because men you've heard before that a man has a sexual thought every 15 seconds Whatever if a man is with a woman He has to be into that woman And he has to stay locked in and focused if not that idle mind becomes a devil's playground And he'll be tiptoeing around before you know it. He'll be cheating He'll be juggling multiple women and that's what a lot of men are doing today So when you are dealing with a man and you come and you say listen, Tony You know a lot of my coaching sessions.  I'm like, how long have y'all been doing that? Oh three or four months six months eight months. I'm like No, sir. Rebaugh. That's that you wasting all of your time Because what's happening is See men have heard of the 90 day rule. They've heard of that I created it in 2007 Steve Harvey made a famous in 2009 But I published it in my book in 2007.  He's not a dependent living off of someone else And and without a job, but he has a job. He has his own place.  It's not a nickel trying to get a dime When that is the case And i'm in that man who has something to bring to the table is giving you an hour a day And I know y'all talking about oh, I don't need an hour.  This is somebody who can steal from you.  You already have your car. You already have a savings He'll be asking for alimony. He'll be asking for everything So if you don't have an hour a day Even if it has to be broken up that you can talk to a person not on text message You don't need to be dating.  There's a lot of talking heads out here But i'm a professional relationship coach. I'm in the trenches every single day. I know what Makes it see a lot of people you just in your relationship. I'm in thousands of relationships So I get to see the data of what makes a relationship work and have longevity And not just the exception to the rule because you may be an exception to the rule I'm talking about the majority. I'm talking about the rule So talk an hour a day If that could be on FaceTime then FaceTime If you live close and it could be in person let it be in person But set boundaries around that because you don't need to end up in the bed And we'll talk about that later on tomorrow calls. But hey, this Tony Gaskin. I just want to try this youtube live Thank you all so much for being on here um I might like this better than instagram live and I could do it landscapes to the portrait So hey, god bless y'all. We'll talk soon in this


These last few days we have reviewed more workstation laptops than ever. First was the Precision 153560 and now we have the HP ZBook Power G7. The latter is a true performer, with its processor choices going as high as the Core i9-10885H, with a server-grade Xeon W10855M also being available. Unfortunately, many manufacturers now have, workstation, laptops, which are powered by low-TDP chips that aren't designed to handle such a heavy load. The ZBook Power doesn't fall into that category as the Core i9-CPU inside is plenty powerful, with even the Xeon processor making total sense, allowing for ECC memory support, which is crucial in certain scenarios. The laptop is also outfitted with NVIDIA Quadro graphics, which are made to handle heavy 3D rendering and modeling work. Today we are presenting you with laptop media's top 5 picks about the HP ZBook Power G7. Being a proper workstation device, the build quality is definitely on point, and that's reflected in the price tag as well. The body is made of 100% aluminum, which makes it incredibly sturdy. There was little to no flex to be seen. The laptop is also incredibly portable, considering the hardware inside and the 15-inch form factor. The laptop weighs only 1.89kg and is 22.9mm tall. Design wise, there is a Z logo on the lid, which is awfully similar to the Nissan Z logo, not in a bad way, of course. Furthermore, there is a small HP logo on the bottom bezel, below the display. The lid can easily be opened with a single hand, and doing so reveals the matte display with narrow bezels and an HD webcam, and an IR sensor for face recognition on top, with a manually operated privacy shutter. Please remember, it would be of great help to us if you just hit the like button and subscribe to our channel. That would motivate us to make even more and better videos for you. The upgradeability here is top notch. Both the RAM and storage can be expanded, through two Sodom slots, which can fit up to 64GB of DDR4 memory in dual channel mode, and 2M.2 NVMe slots, which if you configure the laptop with a Xeon CPU, get support for ECC memory, with half of the maximum capacity supported. If it's your first time digging into a laptop's internals, and you are unsure what to do, we will leave our detailed teardown video, which shows all the necessary steps you need to take, to safely access both the Sodom and M.2 slots. The keyboard and touchpad combination is amazing, as the keyboard has spill resistance and a backlight. The keyboard has decent key travel and a very satisfying, yet quiet click. This makes for a great typing experience and the fact that we saw little to no flex from the base gave us an even better feel when typing. It's not without its shortcomings, though, as the arrow keys are pretty small and the backspace and power button are identical. However, HP has made sure that a one-time click does nothing, so you wouldn't accidentally shut off your laptop. The touchpad is great as well, as it has a smooth, glass-covered surface. It offers smooth gliding and accurate tracking. Furthermore, it has a very comfortable and clicky mechanism. With a battery unit that has 83 watt-hours capacity, the laptop lasts for 8 hours and 15 minutes of web browsing, and 13 hours and 24 minutes of video playback, which is pretty good, considering the powerful hardware that it has. As always, we do our battery tests with the Windows Better Performance setting turned on, screen brightness adjusted to 120 nits, and all other programs turned off except for the one we are testing the notebook with. Finally, the 15.6-inch display here needs some more work. While it has a full HD resolution and an IPS panel, it's not without its falls. We would have loved a better unit, as this one covers only 53% of the sRGB colour gamut. However, the laptop still has other redeeming qualities such as comfortable viewing angles and a high contrast ratio of 1,170 to 1. Furthermore, the panel showed no PWM usage, making it safe to use for prolonged periods of time. Colour accuracy isn't what we would have hoped for either, as even with our design and gaming profile, we only managed to bring the Delta E value to 4.0 from 4.5. Here are the results of the colour accuracy test. Of course, we don't see all that as a huge issue since workstations are mostly used with an external display.


Of course Achilles wasn't bisexual. We don't even know if Achilles and Patroclus actually existed. Maybe they were just a myth, but did the writer of the Iliad intend them to be bisexual? Well, we don't know who wrote the Iliad. Was it passed along? Did Homer write it? Was Homer even an actual person? But the reason we still know about Achilles today is that the Greeks in the 5th century BC discussed so much about these stories. And they absolutely believed Achilles and Patroclus were lovers. Because that was the norm in their society. But that doesn't mean the norm was to be bisexual. Bisexuality is a modern invention, an identity we use to label ourselves and others based on sexual preference. But it doesn't make any sense to transpose that label back in time. So even though Achilles and Patroclus were lovers in the story as it was given to us,


If you remember, we're looking at what happens when a long slender, the axial dimension being the greater one on these type of members, and we're loading it in some kind of torsion or twist. And we found out the other day that the maximum shear stress then will be, of course, a function of the torsional load. This is the applied load just like the axial force was before. Also a function of c over j. Remember what those two things are, what's c stand for? It's true now, and it's going to be true for the rest of the term that we use this c in this way, so it's very useful that you recognize it. It's the maximum, well, right now it's radius, but we'll be looking at non-circular cross sections in a little bit, and so it could be the maximum distance, for example, we could look at t-beams. We're going to find what's called the neutral axis, and then c is going to be the greatest distance from that, which could be either up to that edge or down to that edge, depending upon the geometry of the cross section and where this neutral axis falls, but it does mean the maximum distance from some neutral spot, and for circular things, of course, a neutral spot at the center makes some good sense, so it is the radius for these circular cross sections. We're not actually going to do it, but if you want to just read through one of the chapter sections we're skipping, it discusses, I believe, non-circular torsional, loads on non-circular members, also on what are called thin wall members, which is any very, very thin wall tube of some kind. So that will stand for the maximum distance for the next couple weeks for lots of the things we looked through, whether they're circular or not, and remember what the j is? j. I mean, if nothing else, go by the first letter and see what it stands for, because that always works. Phil, you remember? What does it say with j? My favorite student comes to the rescue, that's the polar moment of inertia. It's just like our regular moment of inertia that we had, we looked at a lot in static slash term, only for circular shapes, circular cross sections in this case. The intermediate equivalent of that, of course, this is just the maximum load, but that's where most of the concern is. We can also look at some intermediate radius, some radius where we're inside the piece, but that's not quite the concern, certainly not on solid pieces, because the maximum stress is at the outer surface. But it could be if we have a tubular cross section, you could be worried about the stress at the inside where maybe there's cladding or adhesive or something similar to that. Alright, so we're going to add to this a little bit now, as we do just what we did in our axial loading, where first we looked at the loading and its direct effects in terms of the stress induced in the material. Then we looked at the deformation under those loads, which is really the step we took beyond what we could have done in statics. We could have done the internal stresses in statics and not gotten out of the general purview of that subject, but adding the actual deformation of the pieces. And we're going to do that now, look at the deformation of some piece when loaded by some torsional load, as would happen in a driveshaft. So if we put a couple reference lines down here, so imagine down the parallel to the axis but inscribed on the outside, maybe not a real inscription, but just for a reference point of view, and then one from there down to the radius and see what happens to that under this torsional load. As applied like that, we expect that this front face here would turn in some measure, greatly exaggerated there, and that the line inscribed on the outside would also have some angle to it. So again, the deformation caused by the loading greatly exaggerated here, just so we can see it, but it would look something like that. So let's put a little bit to this. Let's imagine this is some length dx. We have an angle here that we have already investigated. That happens to be, of course, the shear strain. Remember, that's the deviation from an original angle of 90 degrees. And if you want to look at it from some side that maybe if I draw it on the edge, this reference line that was like that, and now it forms to that because of the torsional load, this is indeed a strain because we can look at this angle here as the original 90 degree angle that's now been deformed. And the deformation of that 90 degree angle is our strain. So we've seen that before. I don't remember if we've seen it in exactly this way. And then this angle on the edge here, we'll call that some amount of deformation dd and then this arc length subtended right there, if that's the right word, is the shear strain times that distance over which it acts. That's the arc length from the axial direction and from the end-on direction. Then, of course, we've got the equivalent arc length, c, d, free there. The shear strain is some geometric constant of the geometry of the cross-section over dv dx and then we're almost ready to integrate that. Remember that we've got this material constant we call the modulus of rigidity which is the normal stress over the shear stress. So we can put that in and we get then combining those two, we get that the maximum shear stress is equal to two constants, the product of two constants independent of the load times however much angular distortion we get per unit length of material. But that maximum shear stress, we already know it would be this. So now we can combine the angular deformation with the torsional formula, the loading itself, and now we can get angular deformation as a function of the load and other geometric properties. So I think that baby there looks like it's ready to integrate. So move the dx over, integrate, everything's a constant, those two things are constant, everything else is also a constant. So we're dx, of course we're integrating over the whole length of the thing on this piece is. And we get then that the total angular deformation is, let's see, the C's cancel on either side, we get T, this integrates just to L and G comes down at the bottom. So I think that the total angular deformation is a function of, of course, the load, the greater the twist, the greater the angle, your angular deformation is going to be. Also the length of the piece, that makes pretty good sense if you've got a real short piece and you're loading it, it's not going to twist as much. When you've got a much longer piece, it's just going to twist more. There's more flexibility in those. You can, you can go home and test that with just a kind of a slender piece of wood. You can just grab it on the ends and twist it, grab it at different places. G, of course, being a material constant, that makes sense too. There are materials, different materials are going to twist different amounts, steels much different than rubber. And then, of course, J, the cross-sectional polar moment of inertia. So as simple as that, I believe, just so you know where we are to anchor it a little bit, that's equation 515 in the book. I'm not sure how many of you have both additions that we're using here, well, including the international addition, but it's around there somewhere. Just so you know where we are. So that's pretty easy to use. We're going to run a little test, test problem with it. So imagine some long slender piece, maybe a drive shaft, maybe an axle or a spindle of some kind, 54 inches in length, 1.5 inches in diameter, with a load of 250 foot-pounds, and a modulus of rigidity of 11.5 by 10 by 3. So we've got, what's that? That's about 4.5 feet long and about an inch and a half in diameter.  They're going to grab the pool cues, right, Travis? You've got this. So you're more well prepared. So we can figure out that name. The amount of twist in the end now. We'll check the units as we go along to see what happens here. 250 foot-pounds, now everything else is in inches, so probably that needs to be converted to feet, sorry, inches, times the length of the piece makes sense. The longer the piece, the greater the angular deformation. The 11.5 times 10 to the third, and this is kilo-pounds per square inch. And then J, I think I have J. I don't need you to calculate it. You can confirm 0.497 inches to the fourth. So we've got pounds, and pounds are going to cancel. Once you take care of the individual, let's get length squared. That's not on the bottom. That cancels that length to the fourth. So this is unitless, meaning then the measure of these angles are, of course, ratings. So you can look at that real quick, see what we've got, the kind of thing we're talking about, how much angle. Yeah, if you don't convert this feet to inches, then it's not going to combine with the other inches to cancel out. And you go to the kips to pounds, or the pounds to kips one way or the other. It might be easy to forget. It might be easy to forget, is that what you said? No, not this group. Some other, maybe an MIT or something, those dudes forget this stuff, but not you guys. No, you guys know to watch your units. It's a hard part. Sometimes they say, yeah, it's the hardest part. I mean, this isn't difficult. You're right, it's when you get the numbers in, and we're working with some very, very big numbers and very, very small numbers, that's as hard as it is to do any of this stuff we're doing here. And don't forget, we can also find the maximum shear stress in the problem by calculating that. Remember, I gave you that little, that little bonus piece the other day once I corrected it from the board. So that's pretty easy to figure out too, and that would have units of PSI, so that's not going to take too much to work with that. Torsion has the same units as moment or torque, foot pounds, something like that. So that's going to have PSI or KSI as the units if that's more appropriate. So you run the numbers and they got them yet? Joey, look at something on your screen. No, I want to share it with us. Yeah, it's 28.3. Radiance? Yeah. Let's see, yeah. There's about six radians in one twist, so that's what, that's about four full twists around. I don't think you can even do that with one of those stringed cheese things. Get that to go full four twists, so I want to check your units here. Make sure I've got everything was right, yeah? All things to match. Somebody else got something a little different? Sounds like you may have missed the unit factor of 1,000. Phil? 0.0283. Okay, that's what I have. So you're the 283, Travis. It just sounds like you missed a little bit. Now that turns out to be about 1.6 degrees, which is more than enough for there to be the possibility of trouble with gears meshing at either end of these if that's the purpose of this as some kind of drivetrain. And the towel max, you get something like 4.5 KSI. All right, so not too difficult to put those things together, but we can certainly come up with problems that get a little bit more difficult since the equations themselves aren't terribly simple. As we said, and as Travis proved so kindly for us, we can get to be down to just a problem of watching the units. In fact, this can be very good if you think about it as a method, oh no, I don't have it on the board. This can be very useful as a tool to actually measure what G is in a material as the actual testing method for determining the modulus of rigidity. Apply load on a piece of known geometry, measure its deflection, and calculate G from that, which is not unlike what we did when we found E. Apply a load, measure the deformation, and then get E from that, which is a little bit different in the actual application. All right, another quick one for you. Now we have some tubular piece with a load. We'll actually determine the maximum torque allowable for an angle of twist of no more than two degrees. Maximum deformation to two degrees by the torsional load that can be tolerated to stay within those limits. We have to work through the same thing using now some SI numbers. What J is for a tubular cross-section, and you know which radius is C1 and C2 because that couldn't be a negative number. That's a tube, so you don't forget. Heartbreak, but that's with rolls. Is that what they were? Do you need to put in the modules of rigidity? Oh, I would, yeah. This is 77 giga-pascals. Remember what the SI prefix giga means? End of the ninth. Okay, again, watch your units. We have millimeters, and they're going to be to the fourth power. So that gets to be a pretty big small number. I appreciate it. A couple students are volunteering to fall for the small trap in this problem, but not everybody under the bus protects the others. Chris, did you find a small trap? A potential one, but you lightly stepped over it. You saw what looked ahead and it would be a quicksand. He finds so far. I keep going. Got a number yet? We're looking for the applied torque. Check your units. These should be in newton meters or kilonewton meters. Whatever is appropriate. I happen to have kilonewton meters. It doesn't really matter. That's a six-one, okay? Oh, something went wrong. Got something yet, David? Yeah. That looks good. So Chris stepped over the trap, but didn't notice there was a pit full of vipers on the other side. Is that right or did you throw that in? Let me go away. Good. Where did you fix that? Okay. Take it out of there. Get in the habit of fixing your own mistakes so you don't come back to them later and not notice that they're on. Phil? What's next, though? You don't have the same answer as he does. Most of you are catching an hour. Just two degrees cannot go in the equation like that. It must be radians. I think most of you caught it by now. Some started without catching it, but most of you caught it by now. 34.9 radians. So make sure you get that. Degrees is a unit that doesn't just disappear like radians conveniently does. They don't stay in there if you have it in there. Reconsider. They'll lose not on a keyboard. Keypad. I noticed everybody's getting that now. Something like 1.83 kilonewton meters. Units should work out. Be careful on these. What's the actual value for that? I don't know if I have it separate. Yeah, do 1.02 times 10 is minus 6. And that's meters to the fourth. This is 60. Remember, these are diameters. These are radii. I don't know why they do that. Why they can't put diameters in here and then pull whatever constants left over out to the 1.5. I'm not really sure, but it's just one of those things we like to do as students. Alright, everybody catch all the little pieces in and get something like that. Not quite yet, David. Can you do something like rock and capillary and gang? You're not getting that? No. Yeah, these are diameters you were given. These are all radii in the equation. Be very convenient if this was based on a diameter and the 1.5 to the fourth was just pulled out and added to that. But that's too nice for us to do. We're not going to do that kind of thing for students. Alright, so let's step it up a little bit. Imagine we have a long gear shaft with a couple points at which power is taken off or added by maybe some gears at certain points. And we've got a couple things going on. So we've got an applied torque and that one an opposite direction on the other two. So maybe the center one's a drive, gear, and then the other two are power takeoffs. So, and then of course the ends are going to be some kind of just a stabilizer, of course. It's all one solid shaft, 30 millimeters in diameter. Let's see what other little pieces do we have. Okay, let's label points A, B, C, D, and E. Because there's different lengths at each one, between each one. So the loads are the applied is 450 newton meters. Take off at B, 275, and at C, 175. And the distances between these, B to C is 500 millimeters and C to D is 400 millimeters. Now the trouble here is, well not the trouble, but the obvious extra complication we didn't have before is between B and C there's going to be a bit of angular deflection, deformation, and between C and D there is as well. And I want to find the maximum deflection and the total deflection. It may be different, most likely they are. Because B to C is going to twist one way, C to D is going to twist the other. So one or the other of those could be the maximum deflection, but the two together, since they'll be in opposite directions would give a different angular deflection. So let's find the maximum shear stress and the total angular deflection. You also need two other little pieces. G is 80 megapascals and the extra dimensions on either end to the bearings 120 millimeters on each end. And as you can imagine the total angular deformation will be a sum of all the other deformations along the length of the drive shaft. So we did a problem sort of like this on Monday. So for any loaded section you need to look at what the maximum shear stress is in that section. I'll give you J so you don't have to do that. Actually, you can skip it and remember to use that little piece we have there. And you don't even have to sleep in a radius. You can use just the diameters given. And of course our usual angular deformation, you will need J for that. So I'll go ahead and give it to you so you don't have to fuss with that. There's the solid polar moment of inertia in terms of diameter. So make it a little easier for you. So there it is in millimeters so you don't have to do that. What's the internal torsion in the shaft between A and B? Between A and B you have to find the internal torsion for each one of these sections so that you can investigate which one is the maximum shear stress and how much angular deformation there is in each section so that you can add up the total deflection end to end. So what's the torsional load A in the material A to B? The internal torsional load. What, Phil? You had an answer earlier.  Yeah, there is no load. Remember for any of the pieces we've looked at it's always based on equal and opposite of either end. For the section A and B there's no torsion here it's just held by a stabilizing bearing. We assume it's a high quality one from A's hardware again. So in A and B from in the section A to B there is no torsional load meaning there won't be any shear stress and there won't be any angular deflection in that section. So it's only B to C and C to D that are loaded because D to E is also not loaded. There's no torsion in the sections D to E for the same reason. Makes sense, Joe? What's the I? The I just has to do with the fact there's going to be a couple sections you're going to have to figure out the angular deflection for each of the sections because each of the sections has their own internal load length, B to C is 500, C to E is 400 millimeters. So that's just an index, a summation index. Don't forget as you calculate these that the angular deformation in the two sections are going to be in opposite directions. So you're going to assign one as negative or just pay attention to what the difference is but the direction of the angular deflection is also important in the end. So you might do well to assign one direction as negative or as positive. That'd be even more, you may have seen wrought iron stair railings where they keep the metal and they put that real nice twist into it. Your piece would be wavy on that. It'd be more like the rubber bands on the wind up airplanes. But at least you recognize something wasn't quite right. I didn't put in a number like that. So check where the places are that things can go wrong. This is millimeters. This is meters. These are millimeters. This is megapascals. These are just straight newtons. So there's a place that things can go wrong. So we start checking some of these. We get a torsion in the section B to C. Well, if we take off everything on the other side, we'll end up at the 275. So that's all the internal load is in that one. And for C to D, we can do the same thing out the opposite end. So we've got the torsional load of means we can double check then what the maximum shear stress is. That's D cubed because that was simplification of C over J and both of them had radius terms in. Yeah, that's from beyond. Double check. Thank you for watching. You're looking for C to D. We have 51.9 megapascals. Now we don't know if that's the maximum because we also need to check the other section of C to D. The shear stress does not depend upon the length of the piece. It only depends on the internal loading and the geometry of the cross section. So if you get this one, again, 16C pi D cubed. Travis, do you have this one? The maximum shear stress? 33.1. Yeah, something maybe a little bit around. Precision of these numbers isn't terribly important because you don't design the very limit of the material's ability to withstand these loads to put in effect the safety of two, three. Remember that the twist is in different directions for these two sections. To be that way, either one of these torsions you can assign as negative and then when you add them together, they'll cancel. But make sure you understand which is the total deflection on that, Travis. Same as Chris. Now you bought our check. For a little while, Travis, you had what, 600,000 radians? Something like that? Yeah, I don't know if we can cover that with a factor of safety. For each of these. I did give you G. So you have to watch out for your units. Tom, you got something? Which proper units? This should be unit. So you have this for DC. Is it 600,000 radians? Is it less than that? Yeah. Chris, what do you have for this first section, B to C? 1, 6. 2.16 to negative 3? Yeah. And to the negative 2. 0.0216. Which do you have, Travis? That or one extra distance? Five. So you're less than 600,000 radians. Alright, well, let's see. The load. 275 newton meters. The length. Half a meter. G, 800 mega-pascals. Everything's in newtons and meters. That's 10 to the sixth square meter. That's a Pascal. So that's a mega-pascal. And J. J is in millimeters. So to get it into meters to one meter, over 1,000 millimeters, but it's millimeters to the fourth. So you have to put that whole conversion factor to the fourth. It's going to be times 10 to the minus 12th for 79 times 10 to the minus 9th. Does that sound right? David, did you get that too? Okay, so now the units are all okay. Newtons, newtons, meters, meters to the fourth. And then what's that come out to be? 21.6 radians. So 21.6 radians? Does it really? No. That's it. Let's make sure I gave you all the right numbers. Newtons, newtons, meters, millimeters. Okay, now I can't read that. Oh, yeah. Sorry. Now look at that. Good. That's the easiest one to fix. Sorry about that. Let's see. So that's kind of the ninth right here. Which is what we need, right? We need three on the bottom. Okay. Yeah, see what happens when you don't fix the little mistakes and you leave them and then find them a year later? Still is. You know, when you take this a year from now, it's the same mistake. It'll be there. So that comes out to be a little better, I hope. That comes out to be 0.0216 radians. 1, 2, 3. Yeah. Okay. And in the opposite direction? 0.0110. So maybe if we call that the positive direction. So that would make this first one negative. And then they add together to give a deflection. They cancel each other a little bit. We still get some in the negative direction. So I know that end to end there's going to be a little bit of a twist in the direction of the middle torque. 0.06 radians or about minus 6 tenths of a degree. We agree on most of those numbers. Joey, you've got those now too. And all we've got is little pieces fixed. Okay. Not difficult equations to use. The setups aren't all that difficult. We'll watch in the unit, especially if I mislead you with the wrong units from the start. What you don't know is I'm obligated to do that because the equations are so simple I have to screw you up in other ways. We talk about that at the professor meetings all the time. Okay. The next little part we need is the, well the very same type of thing we did is we were looking at the axial loadings. After we looked at the loads themselves and the stresses they induce, then we looked at the deformations they cause. Then we applied what we've learned there to statically indeterminate loaded. Meaning just what? What's a statically indeterminate problem? Using just the equations of statics, it's unsolvable because there are too many unknowns. For example, imagine we've got some kind of axial member between two rigid supports. I'm going to draw that. It might be easier just to put it on. Especially since what we have on this form is that it's not a constant cross-section. From one end to midway down. So we have a solid piece per half of it and then a tubular piece per half of it. Right down the middle is a horizontal load of 90 foot-pounds. So whichever one of the drawings you prefer labeled as A and B or the two ends sees the middle. One of the pieces cannot give you a year. I don't have the radii, but I have the polar marmalance of an inertia formula. A is C. It is 57.6 times 10 to the minus 3 inches and 42.6 times 10 to the minus 3. Now the way we get out of the static indeterminacy of this is the fact that because it's mounted at two ends, two rigid ends, then there's no overall total deflection. Using that, we'll be able then to come up with another equation. Well, in fact essentially that is the other equation and we can then solve the problem. Find the reactions at the walls. Oh, yeah, sorry. Our statics only tells us that the reactions are nothing more than equal to the total load, but we don't know how much of the load is at each one of the supports. So we need then to add to it the deflection part that the deflection between A and C must be equal and opposite to that between C and D. So the total deflection end-to-end is zero because of the two rigid supports. So that then allows us to determine just how much is at each one of the ends. Anything missing this time? I haven't told you what the material is. Remember what happened last time with the axial loading? The material constant, this G, in that case it was E, cancelled out, but the solution is the same no matter what this material is. Which I think is always very interesting. And the lengths happen to be equal, which is convenient. Well, it just makes it a little easier. When you set this up, those two will cancel. G cancels, we get just the inverse ratio of the two whole moments of inertia. Wouldn't be that simple except the lengths are the same. Could there have been two that they were different materials? That would certainly have been a possibility. But given that you can now solve that. Now we're down to just these two equations as enough to solve it. So it's a matter of fairly simple mathematics. Now it could be the reaction, so it could be the torsion at A and the torsion at B, the applied load in the middle. And they should be in the same direction, yet 51-7. Now it's just a simple ratio of the two and 38-3. Yeah, if this material is different than that material, then the Gs wouldn't cancel. But the reality is that you would still just retrieve something as having the same density throughout the electricity. Oh, density doesn't come into it. Probably the rigidity throughout the length of any given material. I mean with the safety factor, it's enough to take more. Well no, it depends on what the two materials are. If this was brass and this was rubber or something, that'd be very, very different. But it's not too big a deal. It would just be in here. It would be U-D, G-A-C here, and G-C-D. That's C-B. C-B. All right. C-B there. Okay, again we have to realize what the deformation does for us in giving us the other equation. All right, questions on this one? I'm just going to set up. We don't really have a lot of time, but I'll set up another one for us that just steps things up a little bit in terms of the static indeterminacy of the problems. Imagine we have a drive shaft that looks something like this. Just to add to it. That is hollowed out as well. On edge looks something like there's two applied loads, one here, here, and then some of the dimensions. The hollowed out section is six tenths of a meter. Oops, not quite to scale. Let's clean it up a little bit. Solid part of the big shaft is two tenths of a meter, and then four tenths of a meter for the other part. 30 millimeter OD on the end, twice that for the big section, and then the inside part four millimeter ID inside diameter. G equals 77 megapascals. And now we want to find the deflection of that free end, which we'll call A. Find the angular deflection of the end and we'll be there. And that's all the pieces. That's the length of this section. Rigidly mounted at the other end, so it's zero deflection there. Two minutes or so, so that's the angular deflection of the intermediate pieces for all the pieces. So you're going to have some angular deflection in here, some here, to determine the total angular deflection of that free end there. Double check, see if you can get it. That's like 2.3 degrees is the total deflection of that end. Even with each of those, oh, sorry, double check here. These loads are not in opposite directions. They're in the same direction. So see if you can get the 2.3 for Monday, and we'll do another statically to look at stress concentrations and drive shafts.


Sssssssssss That's drunk! As many of you know, if you've been following this channel for the past while, I got a Super Nintendo in Christmas of 1991, and along with that, we also got Super Mario World and Final Fight to keep us busy. But after that, my brother and I had to venture into the wild world of video game rental. We quickly identified the kind of stuff we liked. For him, it was mostly adventure and RPG style games, like Ys3 and Final Fantasy IV. And for me, it was mostly action stuff like Contra 3 3 and Legend of the Mystical Ninja. However, my tastes skewed much younger than my older brother, so I was still drawn to certain games like Bugs Bunny Rabbit Rampage, Mickey's Magical Quest, and Roadrunner's Death Valley Rally made by iCom and published by Sunsoft in November of 1992. I remember renting this one and really looking forward to it because it looked so good. The art style and sprite animation was pulled straight from the cartoon, and hey, playing an interactive Looney Tunes cartoon like this was pretty dang novel. This game was even featured on the cover of Nintendo Power, so I was really psyched. Then it came time to play the game, and uh, I'm not kidding when I say this was easily the biggest disappointment of my young gaming career at that point. I'm not saying this game is that bad, it's just a massive disconnect between what I was hoping for and what I was expecting, and what I ended up getting was a game that looks the part and sounds the part but does not play the part. To get the basics out of the way first, you get a health meter with three lives and no continues to get through five levels, split up into a few stages each with no battery save or password system. The whole idea here is to pass through a series of checkpoints before getting to the exit, all while dodging enemies and traps, and of course, Weil E. Coyote, who is chasing you the entire time, on rocket-powered roller skates, in a green Batman costume, in a jacked up car, in a train, all of course generously provided by the Acme Corporation. However, if you sit down and actually play this one, you'll realize within about five seconds what the big problem is. Controlling Roadrunner is like controlling a bus. He's this big long, awkward sprite that slowly bounces around, taking damage from all over the place, with one of the absolute worst jumps you'll ever see in a game.   The ideas of what they were going for here between how Roadrunner controls and how Weil E. Coyote shows up out of nowhere, they just do not work together.  In addition to that, this game tries to do the Sonic-style level design, where it's just a mantle of leaning into the right path, going fast and using your speed to destroy anything in your way, but this game doesn't seem to understand that. Instead, the game punishes you for going fast by having random stuff pop up in your way and causing damage. It's like the game can't decide, dude, which is it?  Or do you want to be an exploration platformer? I can't tell. This game is proof that you can't do any of those things at the same time. Why would you want to do that?  And that's really too bad because this game gets just about everything else right. The visuals are great, the backgrounds are straight out of the cartoon, the music is perfect, and seeing Wile E. Coyote show up in ridiculous costumes is always good for a laugh. I grew up loving these cartoons, so I'm practically predisposed to love this game, but good lord, the controls are so bad here, and the game doubles down by coming up with this awful level design that just does not make any sense. 90% of the time, you end up just flailing out of control with this terrible floaty jump, taking damage from stuff appearing on screen out of nowhere, like this construction site level here. You're supposed to run around and look for flags, which unlocks the exit, but Roadrunner's slow-motion jump is infuriating. Then you get the coyotes showing up on rocket-powered roller skates, and there's no way to avoid them. Seriously, there's no place to go. What does the game expect you to do? Ugh.  I think if they shrunk down the Roadrunner sprite, made the jump a little more responsive and cleaned up the level design a bit, this game could be pretty good, but as it is, there's absolutely no way I can recommend this one. It's easily one of the most frustrating games I can remember playing, and it really should be a much better game than it is. All right, that's all for now. I want to thank you for watching, and I hope you have a great rest of your day.


Hello people of the internet, my name is Johnny and welcome back to another week, another FNAF AR video. This time with Blizzard BB, I believe his name is. Now before I talk about the skin, I want to talk about the thermometer meter that is in the game. That apparently we completed.  Last night we were two bars away and today apparently we completed the bar, which is complete BS. Now I'm not complaining that we're getting the character early, but as it turns out we're not actually getting the character early, I'll talk about that in a little bit. I'm upset that they held this giant event, you know, to collect a brand new currency in the game to unlock all sorts of goodies just for it to be rigged at the end. To me that completely ruins the fun. Sure I'll still get the coins, but we needed to fill up the meter to get Golden Freddy, you know, the It's Me hint character early. Not only are we not getting them early, we are still getting them next week, a.k.a. the week that they would have came up anyway. So we're not getting them early, even though Illumix said that we filled up the bar, which we didn't. So technically they lied, but they didn't at the same time. They kind of lied saying that we filled up the bar. Last night we were two bars away, and there's no way that we got two extra full bars in like less than 24 hours. That just, no. Again, you should still be collecting coins because you can purchase like different, I don't even know what we're purchasing, to say goodies, right? They say that we're going to get some goodies. I don't know what that means.  This whole event was just kind of weird. I was kind of hyped for it at the beginning, but now especially that they've rigged the ending for us to win, even though we're not getting the character early. It's just, it's not fun, you know? Like if you're going to rig the end, what's the point in even having a event? Anyways, you're going to find out more of my thoughts on it over on my Twitter at JohnnyBloxBoys. Now, I want to talk about the skin, okay? I'm a little upset that it's still ice-themed. Even though there is some snow in there, he's still made up of snow, but it's still kind of mostly ice. I will say, this is probably the worst skin in the entire event. I'm not saying it's bad. I don't think it looks all that bad. It definitely, it doesn't look right. Like why couldn't we have just gone like a friendly, like snowman balloon boy? You know? Why does it have to be this monstrosity? Again, I don't think it looks that bad. I'm just saying why? Also, what's up with the Lumix and just getting rid of balloon boy's face for his skins? Also, we just had a balloon boy skin. Why did we need, why did we need another one? So soon, especially when it looks like this, like this is terrifying. Why couldn't we have just gone like a nice little, again, snowman balloon boy? He could have had like a snowball for a balloon, you know? His sign could have been made out of like sticks, you know, I've ever had the sticks for the snowman. I don't know. Again, I don't think it looks that bad. It's just not really what I was hoping for. Anyways, so next week we are getting Golden Freddy. I've already talked about how I want him to play out. If you missed my video, it should be linked down below or there should be an I-card up there. But yeah, even though we filled up the meter, which we didn't, the Lumix is just saying that we did so we, you know, feel good about ourselves, even though we completely did not do it, we are still not getting the character early. So I don't really know how to feel about the ending of this event. It's just, it doesn't make sense, okay? If you're going to make an event, you got to do it right. You know, if we don't fill up the bar, that's on us. We shouldn't get the reward. And we're not getting the, whatever. It makes no sense. A Lumix, you got to figure out your stuff over there. Also, like, was the meter even live? Was it real? Because it definitely was not updating in real time, because it went one bar at a time instead of slowly going up and up.  So what's to say, the bar was never real in the first place. Oh no, I'm done talking. Let's move on in-game and let's check out Blizzard Balloon Boy. Okay, so I have bad news. His name is not Blizzard Balloon Boy, it's Frostbite Balloon Boy. What kind of name is that? A Lumix, have you never heard of alliteration? It makes things sound so much cooler and better than they are, you know? Anyway, so, collect- oh, I forgot about that for a moment. I only have like, a thousand, five hundred coins, tokens. So I don't think I'm going to be able to buy anything, because if I know a Lumix, things are going to cost like, thousands of tokens. So that's going to be quite unfortunate. So yeah, Frostbite Balloon Boy, come on man, come on, Blizzard Balloon Boy, that's such a better name.  Come on, that actually makes me a little bit upset that his name is Frostbite Balloon Boy.  Okay, so, um, that's a normal Balloon Boy, where is Frostbite? Here he is. So, I'm just going to go into a fight. I wonder if my game will be glitched this time, because that seems to be a recurring theme when it comes to me recording videos on this game. Look, even the snow has picked up a bit, right, we're in a blizzard now. It does make it a little bit difficult to see where people are on the map. Is that him? I think that's him. Here's his animation. I wonder what it's going to be like. That's Bonnie. I swear, I swear that's on Balloon Boy, though. Get out of here. Hey, Bonnie figure. Bonnie, Bonnie figure, Bonnie. Okay. Got him out of the way. I swear I clicked on the Balloon Boy skin. I don't know why Bonnie popped up for some reason. Hey, 16 tokens, that's pretty nice. Where is he? I didn't click on anything. Oh, it's fine, it's remnant anyway. I can close out of that easily. Here is Balloon Boy. I gotta fight this guy. Did I see him? Here he is. Okay. Geez. Oh. What the heck? What is that? Animation. What? It also looked like he was glitching out a bit. I don't...weird animation boys. I don't really like Balloon Boy because...oh, he's like walking in the snow though. That's awesome. I don't like fighting Balloon Boy because he can be very annoying. Okay, his chore just kind of fast. Luckily, the static is kind of small so you know where he's going to be roughly. He's also very small himself. Oh! Oh no! Boys, he has Bross Bae's mechanic. Oh, shoot. I hate that.   One of the most annoying ones ever. Okay. New opinions on this character, on the skin, whatever. I like that they finally switched it up. Finally, a character is a bit different, you know? What the heck? That's why I don't like Balloon Boy. He's very annoying. He can be very confusing. So now that I know that he has this mechanic, I'm actually going to actually try. God, don't do that. I'm actually very surprised that they gave him a different mechanic, you know? Usually that's only four different characters. Got him! Ooh, he's terrifying. He's terrifying.  Did he get anything? Blue balloon? Hey, good luck, maybe? Nope. Okay, just some tokens. Okay. Well, honestly, I like that they gave him a different mechanic. That's going to be a bit weird seeing as it's a skin and normally they don't get mechanics. So that kind of opens up the possibilities for skins having different mechanics. It makes me wonder why Ballora didn't have that feature, you know? Like, maybe it's only four frost characters. What was Ballora's skin called? Arctic Ballora. Maybe it's only four characters that have the word frost in their name. I don't know. I'm going to have to see what happens if they do anything like that in the future. So thanks for watching and I'll see you next week with hopefully Golden Freddy. Goodbye. Gregory, be still. I think she's found us.


Time waits on no one.  You sound like someone that eats plain cornflakes with water. Like, relax. You were early to bed, early to rise, little soldier. Men's irons is socks. Men's irons, the blades of grass on his lawn. Y'all anxious little herbivores. Y'all too afraid to get in a bad result. I need to plan accordingly, headass. I need a man if that's my destiny. Alright, look what that got us, huh? Look what that got us. If I look into a crystal ball and saw myself 40 years into the future as a bum-selling stolen inflatable balloons on the streets of New York, I'd be like, damn. It is what it is. And just start rubbing my hands together real nonchalantly. You're glorifying being an underachiever, okay? Sluffing? Is it sin? A sin I say? Good. Sin all you want. Sin till you can't sin no more. Sin till you get all that built up angst out your spirit. Just make sure you ain't hurting nobody. Just make sure you're gonna pick yourself up at the end of it all. Time waits on no one. Well, for me it does. For me it does actually. Could you believe that? I'm taking all the time I need. I'm taking my time like it was old to me like the refund from the IRS.   Time waits on no one.  Man's thought he was chowing at Chick-fil-A. My nigga, you biting at Burger King. You grabbing a high blood pressure junior.

Please enjoy it. Be excited. You can see it will be probably quite a show. I'm looking forward to it. I have you too. Up to this, there will be the final competition and the closing at the room upstairs. D105. I believe it's the number. Please join us for it as well. That will be all from my side. Enjoy. Have a nice time. Thank you very much. We're here. You're all here because you just love developer evangelists. We don't need to be mic'd up. Most of us can talk pretty dang loud. First thing I want to clear up. Even the will cluster just did an awesome session. No monkey suits are required to be a developer evangelist. Today we're going to run this as an ask us anything within reason. Within reason part. Given who we are. That reason is a very small. Universe of acceptable questions is quite large. First what I'm going to do is ask each of us to start with Ryan on the end. He's the tallest. That's why he's sitting at the end of the stage. It makes us all look uniform but we're not. Ryan to tell what you evangelize about around OpenShift. A little bit about your background. I'm from Oakland, California. We consider the capital of the NodeJS empire. I focus JavaScript and Node as my specialty within the OpenShift team. What other projects did you work on before coming to Red Hat? I think that's actually interesting. Yeah, I actually as previously I worked at Second Life as anyone heard of Second Life. Virtual Worlds, okay. I was a Linden lab employee and after that I worked at a company called Eventbrite. They sell tickets online and so I was their first developer advocate for Eventbrite. If you're interested in being a developer advocate start within your own company. Promote your AGI's whatever you have and that's how I got my job experience that qualified me to join this team. Jorge. What's the question? I just came. He really did just come on to the team recently so not quite our newish one but how you became a developer. I'm from Mexico. I'm from Mexico. The Mexico that's in Europe. The Spanish is Mexico. I joined the team six months ago. I've been in Red Hat for two years so I'm bringing real expertise to the teams. More on the enterprise side so I usually not that much with developers from external but more from user consumers of our products. I don't have any other hobbies or backgrounds or side projects so I live in my interview and I got the job. And our Chexicon. Chexicon, yes. So I'm local here. I joined the team. Your name? My name is Marike. I joined the team in one month four years. So I'm four years on the team. He hired me, I'm not sure why. I think I was very active in the communities. I was active with open source. I did Rails engineering. I did Rails consultancy. We'll be consultancy et cetera et cetera. And yeah. As we may get fired if he ever wears a collared shirt again. I don't know what's going on with this today. I don't have any business before so let's get in here for the session. So should I say why do you that's good enough. My specialty will be Rails probably. Yeah. And Graham who is our newest developer advocate. We call them... Not chronologically on this earth. The newest on this team. When was the least amount of hair? Yeah. I was born in Sydney in Australia. So yes I've been with you Red Hat since July. Although how I've been on the holidays so much that time it seems. I came from a company called New Relic where I was basically doing Python development on their agent for the monitoring system. And after doing the program for so many years I was just sick of it and I knew some of these guys. I knew what OpenShift was all about. So a big interesting when I basically said I want to work there and I knocked on their door and kicked it down and got myself in. And what was that little project that you worked on? Had to do with whiskey? So how many of you have heard of ModWizky in the Apache? Really? That's it? He's the author on ModWizky for Apache which is probably the most used... Not anymore. Last ten years? Yeah. Okay, last seven years was the main way people wrote in Python. Alright, so I am Grant Shipley.  I started my career as a Java developer at a company called Caldera. Anyone heard of Caldera? I was one of the three people responsible for the Linux lawsuits if you remember that. After Caldera I went to work at a company called Novel where I worked on the SUSE installer. So I wrote part of that for a SUSE enterprise server. Came to Red Hat as a principal software engineer to convert all of Red Hat's legacy Perl code to Java. And then I came over to this new project we were creating called OpenShift and I wanted to try something new to be a developer of Ageless and then we grew and I ended up being the manager somehow. He's actually been here, you know how? He's been here the longest. How many years now has he been at Red Hat? Ten, something like that. He's the oldest member of the event in terms of team age, he's the oldest member on our team. I'm Steve Housty if you want to remember the last name. My background is I actually have a master's in forestry, a PhD in ecology and as part of my PhD work I wrote a lot of simulations and I ran the computer lab for my ecology department. I then went to Yale where I did internal IT projects for Yale where I would build websites, design databases for faculty members. And so then after that I got tired of just doing that and I became a developer evangelist at ESRI it's the Microsoft or the GIS world, Spatial Stuff that was about ten years ago. So I've been a developer evangelist for about ten years and I joined this team after that I was a developer evangelist at Ducarta, has anybody heard of Ducarta? The LBS company they were just recently acquired by Uber. I left before that and I'm thankful and then I worked for LinkedIn for three months because that will be an interesting story if anybody wants to know I was a developer evangelist at LinkedIn for only three months. Three months. Because once you get those, once the stocks are just investing, it becomes very hard to quit. So I wanted to quit before I got hooked and became miserable. And so then I joined Red Hat I'm here a month longer than married. Cool. And I'm Diane Heuler I am the community manager for OpenShift and the developer evangelist and so my background I'm the oldest on the team and the only woman we're working on that and I came from a small startup company called ActiveState any of you ever use ActiveState Python, Komodo and all those kinds of things I was the product manager there and did a lot of R&D work and I was the gal that convinced them to create a fork of Cloud Foundry and turn it into staccato and did all of that work and I worked on that project, the Cloud Foundry the competing project to I'm from the other side and then I got tired of some of the crap that was going on around the Cloud Foundry community and wanted to go work in a real open source world and came over to the red side and started working on OpenShift and I've been here almost three years now doing that and very happily being a lot more open I'm the author of some XML stuff I worked on an XML standard called XBRL so all really boring accounting stuff but it's used globally now in the US, at the SEC in China, all across Europe you can blame me for some of the most complex XML ever written in the entire world and still being written for really boring stuff like corporate reporting all kinds of filings and things like that so I worked on that, I came from a company that was once called Softquad I worked on a project, a product called Xmetal anybody here know what Xmetal is? XML Editors, yeah I did that, that company was acquired by Corel that was then acquired by another small company called Blast Radius and acquired by a company in Japan called Just Systems I've been around so I was at the same desk the entire time it just changed business cards but so I did a lot of XML work before that and during some of that I did a lot of Python so you'll know me on Twitter as Python DJ and if you're following me I'm sorry you'll see pictures of my dog in unicorns and a lot of open shift messaging so that's sort of my background I've been around for a very long time my very very first job outside of university was at Nike the sporting shoe people I would get a lot of CAD cam work and 3D design and on the side I run at Get Makered Labs which is a mobile maker space and so I asked me about that afterwards and I'll be very passionate about teaching kids how to do 3D design so that's what I wanted you all to do I wanted you to introduce yourselves and this has asked me anything I figured I'd see it with a question for our fearless leader what is the rule because we always debate this in our club we have just been here for a solid week in boot camp getting training figuring out our planning for the next year so we've been drinking a lot of really good beer here in Bruno but we all have different opinions about what the role is yeah I think so for me the role is to get developers excited about new technology and how they can use it in their projects we're not salesmen we're not marketing we're actually there to help developers do something and so in order to do that we actually have to know how to do it ourselves so a lot of people think of just kind of just talking heads and that's actually not what we are we actually go in and help developers with code most of the time it's what we do so I made a video about this it's called the feeding and husbandry of developer evangelists you search on this don't do it now please and you look on YouTube that'll be the video where I gave my whole entire opinion my basic opinion about what we are our role is to be a bridge we're not any one thing and yet we're pieces of a lot of things so we are part marketing this is where I disagree with Grant we are part marketing sometimes when I go to conferences and I'm giving a talk it's almost purely a marketing talk it still has to have information in it but it's not necessarily like when Grant gives a talk on Python Grant sometimes goes so incredibly deep that I could never go about what Schwag works do you know what Schwag is that's Schwag the scarves are Schwag and so sometimes when you see it chose you can tell when there's a developer marketing versus non-developer marketing how many of you like this try to think of what's non-developer marketing Schwag I like the coffee cups coffee cups works as they're actually like the squeezy toys how many of you pick them up and then almost never use them right? like that to me is a waste but if you get actually I wanted to get nerf guns right? that's good developer marketing so we're also sales but not really sales so we need to talk to the sales we're also engineering but not really engineering so open-shift engineers raise your hand two, three what am I really good at you can say it be honest complaining bitching so that is my a lot of times we're called advocates and not evangelists and the reason why is because we go to shows these guys sit at their desk all the time and just code we actually go to shows try to get developers to use the product we watch them fail and then we come back and complain at these people the whole time this is crap how can we release it like this we should be not that open-shift has any flaws it's perfect it's perfect because of the complaining we did very early on in the process and then we also meet with PM's as well so Mike what else am I really good at yeah because what our job is with the PM's is to say your road map sucks this isn't helping my users we're developers we bitch about what developers need if someone wants to bitch about what sysadmin needs or enterprise customer or enterprise sysadmin needs I don't care someone else can do that I'm on behalf of my users I'm advocating back into the company I think the key here is the bridge because open-shift being a platform as a service touches on a whole swath of communities and so while we're presenting and trying to connect developers to open-shift and get them all excited about this and get that feedback we're also touching on kubernetes docker open-stack so you'll see us show up at open-stack summits or kubicon and other places where we did a lot of work with mongo dv on v3 so we're all over the map and we're not necessarily experts on any one thing a lot of us are spread a little thin sometimes so I think it's the feedback loop that's really important that we play to the pms and the engineering teams but it's also all that cross-community collaboration so when open-stack's about to do something new with neutron we get heads up or we try and demo it and it fails I don't try to demo it I hate that stuff but Ryan the things that we're saying here clear this is not particularly the open-shift team this is what it means to be a developer advantage so how many of you like to sit with your head down all the time and write code all day you are not going to become a developer advantage you can't do that you can be good at that but you can't do that like Ryan when you were at event pride you were doing some of the same tasks that we do now getting feedback I was actually within that company part of the marketing team but organizationally I was part of the marketing team for a while because they didn't have anywhere else to stick me within the company they also I moved over to the product management team for a while so depending on how your company is structured you may get put within one of these other camps right but it still should be your duty to advocate for the needs of the developers the needs of the users and give that feedback back to the product team so I think we didn't actually answer the question of what we do so what do we do we give conference talks we write sample applications we write reference applications for the product we give trainings workshops, write blog posts we have to have an active twitter following we have to be influential in some type of community like Steve is pretty well known in the geospatial in python etc etc and so we kind of have to be respected in the communities that were targeting so like if you asked me to go and talk about Node.js I wouldn't go I would have run so we build teams around different interest areas but that's mainly what we do conference talks, blog posts stuff like that and use the products essentially you have to be deep usually you have to be deep in two technologies one is the one that you own one is the other one that you work with and then you have to be spread on so many other technologies see what's happening in python see what's happening there all the emerging technologies have to look out into the future but to the technologies always at least you have to be deep should be to a certain level I wanted to interrupt you because you're going to have to just stand in front of me and also one important thing is that we socialize a lot we need to socialize and listen to the people to the community that we so we like to hang around we like to go for beers, talk with the developers because at the end the developers what they do is the kind of things they probably don't like to talk to the real marketing guys to the PMs or whatever because that kind of engaging with them is really difficult we are really easy people sometimes if you go with deep you will want to go to the hotel very soon but if you go with people like that probably you will get and you can tell who's been on the team longer based on our size because of all the time we spend talking with you I'm going to actually disagree with Jorge just a little bit because I have to that's what I do but two, how many of you are actually here because you're thinking about wanting to become a developer nobody? come on now that they understand what's required the only thing is we're not all extroverts so Jorge makes it sound like we're extroverts and I seem like an extrovert right now on stage because I talk a lot and I'm very outgoing and at the booth I'm very outgoing but when I'm going to go home after this week I'm going to sleep for an entire week and I won't want to meet people I don't want to do anything I'm just going to walk in the woods with my dog so I turn it on when I get on stage and it's not that I'm lying it's not like I turn it on and start lying but I turn on the persona and then I turn the persona off when I actually am by myself and if I keep doing this for two this week I'm done like last night Jorge and Ryan wanted to go out drinking and I just went back to my room and watched YouTube videos and laughed a lot so don't think you have to be an extrovert to do this and I hate people all the time it's true and I also hate traveling so I hate people and I hate traveling that's why I got this job and he's our manager and that's actually something else we do a lot traveling so one of the things that's required with this position no matter what is travel you should like at least at some level to travel if you're going to do this and then depending on the company we travel generally less than sales people and essays I would say and consultants right but we do travel we travel way more than engineers I wish engineers would travel more with us because they're actually really good to have in the booth because we get a lot of deep technical questions plus they also get to see direct feedback on their product rather than just hearing it from us we travel anywhere between a quarter to almost a half of time but it's not all year long it's in bursts usually my longest trip was three and a half weeks I think I was on the road I worked every day for 28 days my longest trip is probably about two and a half weeks where I was out of country the whole time and any trip may as long because I'm so thought for bringing in probably a week and a half or so I think I had 32 days with two days one time I met my wife at the airport for lunch when I was flying in and then flew right back down and how many children do you have? I have four kids he's managed to be home a little bad not more than 10 seconds each trip just deep the acceptable boundaries were very very very we can go anywhere where you want with the questions so one of the things we were talking about what questions we were going to ask and what if I don't like public speaking can I still be a developer advocate and I think Jorge you are I think that you can unless you have cojones we are Mexicans so I am Mexican one of the things that he's not really from Spain but I'm not like the Mexican because we're the ugly Americans I basically look like a Mexican you speak Mexican? I speak Mexican what was the question? it was about public speaking it's right above you I was afraid of public speaking and still I'm afraid of public speaking and sometimes you are speaking to the public and your legs shake and you think that you want to overcome so if you want to do it it's just a matter of training and doing it it's still more than that I was actually a professor and a teaching assistant probably about 17-18 years I've been public speaking one of the things Katie Miller she would come with me it was her first year and she's like oh you're so good I could never be like you she was a really great at functional languages and if I sat down and started writing I was like I can't write like Katie I'm never going to program so it's a practice and you just get good at it and you want to turn it on and off and a lot of people say when they see us give a talk like Steve give a talk then we go to larger user groups and then we submit talks to conferences after we've given it 10-15 times so when you see a talk that's great at a conference it's not the first time they have given that talk I think that's a big misconception for me whenever I go on this page I am nervous I go there and then there is no time to be nervous you have to do the talk then you go out on this page and you're like hell was it good or not and you and I was again and it's the only time that you are not nervous we did that one I was just going to say but I forgot because America like you needed to talk instead of me I'm sorry Steve there you go so another thing we talk about a lot we bitch about a lot I have to say is how much coding do we do and what we are always complaining about is we don't have enough time to really do coding that's been our complain to our manager that we should have a month off so that we could write more sample apps and things like that and it's probably the most frustrating part of our job is because we're all in tech because we love this stuff we want to play with the way it go or Node.js we want to build super awesome demos but it's really hard to do that when you're in a hotel room at 2 in the morning and you're trying to get your slides in or a call for papers in or answer 20 million emails I don't do enough actually that's one of the things so we can all be really honest here do you want us to all be really really honest here because I don't know yeah exactly I have no morals so honesty means nothing to me it makes stuff up all the time so for me though I'm a New York Jew and so we are very emotive and we like to share and talk amongst each other I've noticed that when Jorge and I argue which is not even really arguing but we're like this how would you even believe that if America's like please stop the police are going to come we're going to get in trouble it would be really rude to this mostly check audience if I actually engage in that kind of discussion no nobody's going to stop so I've actually gone through a period of depression probably for a very long time but for the last three months I've actually been pretty depressed we did a very intensive road show in the fall and I was burnt out after the end of that and I haven't written much code and that's the part that's bumming me out the most right now because to be an effective developer evangelist you actually have to write code because I can't go to developers and be like this is a great experience or this is a terrible experience or this is what you usually do with any authority without actually writing code every once in a while and so when we've been doing a lot of traveling and not having most of you write code is that right are most of you developers yes thank you so you know that you guys talk about interrupting your flow and that's just somebody coming and knocking on your cube I can't get into a flow state ever basically and so it becomes very hard to write code that is what I'm struggling with right now as a developer evangelist is being able to get back into a period of time where I can be in flow state but I think I think that's part of being an authentic speaker you need to have experience and you want to really defend internally the needs of the developer community and if you're not always giving developers good advice and reasonable meaningful advice and you start selling them a bunch of BS that they don't need you'll ruin your reputation over time right and so you really need to have hands on experience as part of the job I think I'm the only one really do a hand but I'm probably the only one that actually can code because I'm writing and I think I know that we are using and whenever they need some picture there I am forced to do it which is awesome because I can code but I actually probably have a slightly different view to the others on coding because in my previous job you're always flat out coding all the time you might work 40 to 50 hour weeks because you had to that was your job now I may not code now as much as I used to but I'm working on things I'm finding much more enjoyable and that's more important so it doesn't matter to me that I don't code all the time and I'm having these breaks and all things because that's actually good for me because most of the time I want to code on something and then I get stuck and I want to think about it for a while so for me it's actually a really good balance to be able to just not code so much and have that break I agree with Graham I don't get to code a lot I coded last week but like he was saying when I code it's on stuff I want to I don't have anyone telling me what to do I just get to make up something and work on whatever I want well that's not it it has to be somewhat related to when I was working at LinkedIn I needed to work on a LinkedIn sample app when I'm working on OpenShift I can't sit there and go oh I'm going to write an app someone told me that that way you still like your job so well we'll meet after this so I think all of us have like little sample apps that we keep iterating on and playing with and I've got a musical jukebox thing with SoundCloud that I've been working on and trying to get into OpenShift 3 and it's frustrating because you want the back end to run there and then someone comes out with another great red hat mobile and the Feed Henry guys have this amazing you know iPhone app development environment and you want to play with that too and you get distracted because it's like a kid in the candy box at red hat there's just so much stuff and then a call for papers comes for OpenStack Summit oh god I got to try and deploy OpenShift on OpenStack again it's endless what you get to play with but it's endless too so it's a little bit of how deep can you go down the wormhole and that's really so how much, no one raised their hand when they said they wanted to be at the back maybe one person raised their hand yeah one person said the two people maybe what are the rest of you here for I mean I'm serious because I want to know like we can just sit up here in t-shirts but most of you are what are you here for I didn't fix my end because we used to do adventures and not adventures this is a big debate in our community about what's the proper term I think it's just words we both do the same job but some people get defensive and no I think it's different it's more about inside out or outside you know because I've never seen a company where they have both the company usually had developer evangelists so they have developer advocates not both so there's not a dual role it's just how they like Google didn't like the evangelical like the Christian implications of evangelists so they went with advocate before that it was always developer evangelists in an airplane that I'm an evangelist especially with his southern accent conversations after that yes I will have four more Jack Daniels so who here wants to be a developer evangelist developer advocate a few there's more now it's getting better alright good news we're hiring an A-PAC there was only one A-PAC guy in here I don't even think in the morning how much coding you do and I think Diane touched on this is that one of the things that you do need to be as a developer advocate slash evangelist is curious I know developers in general like to chase after shiny objects but you tend to have more of that because you're a bit more comfortable being an inch thick and a mile deep on only one or two things so you have to be comfortable and looking in like what's the new thing I can play with or that's how you learn the new technology well I put this one I stuck this next question in but are there any questions in the audience because we have ten minutes left ten minutes left okay there you go you said that you were both a community manager oh it's a lot of it's a lot of fun actually so I still get to do all the developer evangelists do the calls for papers go out there and advocate for people to use open shift but I also have a role in this specific business unit of being the person, the community manager who connects with all the other open source projects that we upstream in so I get to sit on Kubernetes management community manager calls I get to go to OpenStack and try and connect with all the people there of course people into doing heat templates for me and I just basically have to do all of that plus doing the recruitment and trying to get people to contribute code back I run the OpenShift Commons which is our community a hub so trying to get organizations and everybody so we have now a hundred and seventy seven companies in it we have thirty five companies that have organizations that have contributed code to OpenShift and so the Commons model is a little slightly different so basically I do two jobs right you need a couple more to stay busy so I remember the thing I wanted to say and it's related to what Grant said all the things that we do we all do those but we don't all do them all equally well so when we went through that list don't think like public speaking Grant hates it and doesn't want to do it as much anymore but he'll have to do a little you can do a mixture but you'll have to do all those tasks you don't have to do them all equally well that's all Graham loves writing blog posts thank goodness so we'll be doing both of those tasks but Graham will do more writing and I'll do more speaking and I'll trade going to one conference for Grant writing a blog post so you'll see a swap back and forth he'll write that blog post I'll do that speaking at that conference so he gets to stay home I'll do the follow-ups so the way I follow up with the people I meet as I say you email me otherwise I'm never going to email you that's really hard that's the hardest part for me is you meet people because you're giving talks and they come up and talk to you and then you see them two years later and they come up like you remember everything about the conversation and you don't and that's what makes me feel the worst because there's just no way we meet thousands and thousands of people a year and actually have like five, ten minute conversations with them but we don't remember or I don't I don't take them anymore and they say oh well I'd really like to I was like okay here's my card if you're really interested enough you'll contact, I'll say contact me and if they never contact me which 99% of the people never do then I'm off the hook I don't want that on my soul to have to not contact them so I have a slightly different opinion because as the community manager I have to try and connect you and get you inspired to work on our project or work with our project or do something with us so I tend to be the one that does take your card and you will get an email back from me you join the commons, you can get into on our mailing list try and coerce you into giving a briefing or becoming what we call before an accelerator which is basically an external evangelist for open ships so there's lots of different ways we all work with the external community but yes probably half of you will come up to me and next time I'm in Bruno and I'm really good at making that face I'm like oh yeah I know who you are I think one of the weirdest moments in my life I've been doing this for a year and I was at Java 1 or some conference and somebody came up to me and was like oh I finally get to meet you in person I've always wanted to meet you I'm like what the fuck are you talking about dude and I called my wife and told her I was famous people read our blog posts and stuff and it's kind of a weird feeling when you first get into it yeah so yeah there's another question here he can't do it he always talked it out well I didn't hear the question yeah basically you have different methodologies I call them open universities not sometimes actually I do so like I talk a lot in Asia we let them go there yeah and Asia is I actually will tend to speak more like this when I go to Asia because their English is not as good but it's way better than my ability to speak Chinese or Malaysian but it took me years to get that cadence down and I'll do it sometimes you guys all speak English relatively well but if I go to another European country when I know it's mostly non-English speakers I'll slow down as well it also helps to teach kids I do coding events with kids on the weekends too and there you also learn to change your cadence you just have to get it's practice the same way like oh I'm in a functional language now I'm in a procedural language you need different mindsets the same skill just like that but the problem is that sometimes you don't know so you go the first time to somewhere but you don't know what's their habits so I've been for example in a country where I didn't know that they have this sense of privacy so I was I'm probably I like to talk with the guys so I'm going out having some beers but I couldn't but I tried for the first week until somebody told me you are invading this private space so sometimes you don't know and you don't screw it up You talk about your role when you release that activity and how do you first started OpenShift our job was to get developers using the platform and so we did measure it then but once we got to like 500,000 we stopped so we don't measure that as effectiveness of our team the way we're measured now is based on the amount of content that we create and the survey forms that you guys fill out at conferences to let us know if the talk was good or not it's not just the technical information like people want to be entertained even at a conference they like talks that entertain them because they don't remember anything you say except for one or two things but they'll remember that it was good talk and that guy worked at Red Hat I should check it out I want Lucy to stand up Lucy is our HR hiring person here so you can check in with her she's our advocate there's also a Dev Evangelist manifesto that we wrote that actually came out of our document as a team that I then put up in a, it's an ASCII doc up in, I forget, is it in our GitHub repo or my GitHub repo it's a manifesto that talks through a lot of things we did, like this was not enough time to talk through a lot of stuff like what's a good company to work for what a good interview question what should you expect what should you be expecting to produce we just barely touch the surface it's a relatively new field and so you get into a lot of confusions and a lot of different companies about what's a good developer evangelist what's their role yeah that's also a big benefit because a lot of companies are starting to hire this position which makes it a very sought after position we honestly get job offers at least once a week that's a bad week actually we live in North America and I'm in the Bay Area and Ryan and I myself probably get the most as we're already there like every startup now Vancouver BC and it's like LinkedIn I hate I'm sorry I don't live here you won't get paid as much as an engineer maybe certainly in the beginning you'll be worried about compensation in the beginning depending on the company they will not see you as valuable as an engineer those are some of the things you need to suss out and figure out when you're interviewing too is to really ask them I'm out of time there's no sessions afterwards there's one upstairs what's more important us or prizes we've got plenty of t-shirts and scarves still all right thank you very much no monkeys are required but they're optional you We've been there actually in November. It's like a little weather around. It's a matter of being able to see this opportunity. I've never thought about joining this team. One day in a chat someone said, if you're worth it, you'll say, why not? If you're going to think about it, I think it's going to be great.
