Hello and welcome to TV and with me is Bob Cook from Manchester Institute for Psychotherapy for his usual book investigation and review and there's an interesting book here it's by Rod Boothroyd one of Bob's former students at Trained in TA and it's called Jungian male archetype shadow warrior magician lover king guide to male archetypes it's a bit of a departure from TA isn't it sir Bob? Well Rod trained you know trained at our place at Manchester Institute and became a TA therapist and he I went on to work with the shadow part of the male if you like so he went to work specifically with men and had an interest in the young ideas of the shadow in the male archetypes and it's not too far removed from transaxon analysis in a way because if you think of Jungian's descriptions of male archetypes and the shadow in particular he's talking about the cut-off disowned fragmented parts of the unconscious which Jung called the shadow and in TA it's simply part of the ego if you like which get repressed yes so it's different language with different way of a similar way of thinking about it really and it's an interesting way because myself I've worked for years 30 odd years now working with the cut-off parts the repressed part or the shadow part of the unconscious if you like and a lot of my work has been healing and working towards integration of the different parts of the self so it's interesting it's an interesting departure in terms of Jungian ideas but in terms of similarity in what he was trained in you know as we say you and me have said many times many of the Bob models actually meet in some ways yeah it's very true Bob and I think it's quite it's quite interesting that it's male archetypes and you were saying off camera Bob that he'd really brought this up to date he contextualized it for modern men I guess so what did what did the archetypes tell us for those people who perhaps don't know archetypes warrior magician lover king what what would they represent what would they look like in terms of how how we would view somebody or or a you know males in general I guess they represent in many ways and I'm not as specialist in Jungian archetypes but anyway we're put the repressed parts of the self if you like so warrior would mean what this speaks obviously with the male repressive warrior in us that the external leader if you like a person that is taking the initiative of the male and then you've got the magician often called you know the trickster in some ways which is the intuitive magical part of the self and TA you might want to think of in terms of the what Claude Steiner called that intuitive part of the self and then you've got the king which is the real sense of authority in us which we often bury in terms of defining ourselves and then you've got the lover that romantic part of the self which often again gets cut off so they represent cut off parts of the self and if you go and read this book of course which I skim through not in great depth but I was interested in the palace TA then he is talking about a model of the unconscious in a way which parts of ourself get repressed into yeah so it's those parts of ourselves that might not might want to come out I'm thinking of I'm thinking of the lover someone who's afraid of showing emotion maybe and that is intimacy intimacy yeah or all the warrior someone who's fighting the standing up for themselves yeah being assertive in the world yes absolutely so it's brought up today so in terms of the audience for the book Bob who would you say the audience is well this is interesting of course it's for it's for people I think who are advanced practitioners I mean it's very interesting beginning people but you know but by the time you've done a four-year cycle therapy training you've started to really understand the connections between the past and the present and how trauma is dealt with so for example how we deal with trauma is to cut off parts of ourself repress them so they actually get disowned from the self so for example so the more a person starts to learn how to be a psychotherapist the more likely they are to understand how to work towards integration of these different split-off parts of the self whether it be the romantic self the person that's afraid of intimacy the person who finds it very hard to be assertive in life these are parts which get caught repressed specifically with trauma yes I was that's what I was going to ask because these these these are the things that get pushed away in traumatic situations lost or become unavailable to people so it sounds like a book for advanced practitioners all those people who just have an interesting young young is of a perennial interest I think to anybody in the therapy world because these ideas are I think it's just so different in a lot of ways from traditional models of therapy where he goes to a more spiritual place a more symbolic place because these are symbols the simple they're romantic symbols they're symbols which talk about repressed parts of ourselves and of course what also talks about how to facilitate groups what he calls shadow groups so men getting together reclaiming the parts of the male psyche which they've repressed and how to how to really bring out and externalize the male potential of themselves in the modern age well Bob I think I think on that very precise and very kind of eloquent note I'll just say that we're gonna put a link to the book below have a look if you want to buy it Bob doesn't get paid for these reviews he does it for the love of literature to share his knowledge with you his vast knowledge with you and there's always Bob Cook thank you very much yeah it's book number 85 book number 85 well there we go and why don't you have a look in the playlist for all the other books the other 84 that Bob and myself have reviewed on Bob's review yeah great thanks a lot Bob bye bye


Hello students, I am Bhargesh Deshmukh from Mechanical Engineering Department, Valchin Institute of Technology, Sulapur. This session is on design of bevel gear part 2. At the end of this session, the learner will be able to derive the equations of forces on the bevel gear. Then what are the different forces on the bevel gear? Let us consider this as schematic representation of a bevel gear. It is a cone, the center line, the line of rotation or the axis of rotation. It is mentioned, it is counterclockwise looking from this end. This is a pitch plane or the plane of rotation. At this point I have drawn a tangent and particular pitch point is considered over here. You can think upon why we have considered the pitch point. This is the plane in which we will find the resultant force which is indicated as Pn or P. Pn is always inclined at an angle alpha which is equal to the pressure angle. This is the box where we need to analyze the forces. All the lines, this line must be parallel to the axis of rotation. One line must be perpendicular to the axis of rotation. And third line, it must be also perpendicular to the axis at the pitch point. I can resolve this force and get the first force which is the tangential force Pt. Pt must be opposite to the direction of rotation as per the convention. Then the other force, if we resolve this force into two, one is horizontal, another is vertical component. This component, vertical obviously in the blue plane. This separating force Ps, I need to check this force. This is neither parallel to vertical, this horizontal or the third component and hence I need to resolve this force also into possible two components. This is inclined at an angle equal to gamma. I need to consider this frame of reference green. First force is the axial force as it is parallel to the axis of the shaft. Second force is the radial force which is always directed towards the center of the gear. At the pitch point, we can show all the forces. Assumption in this analysis is, the force between the meshing tooth is concentrated at the midpoint of the paste width of the tooth. Pt is the tangential or useful component, Pr is the radial component and Pa is the axial or the thrust component. This is the analysis gear rotation, point O is the apex, point D is the pitch point line OD. Direction of rotation is counter clockwise. There is a triangle on which we are assuming that all the forces are acting at this particular point which is a pitch point. AD is the force which is perpendicular to this line OD. A red zone this, it is the plane where force P or the resultant force is acting. This is the resultant force. We may call it as Pn, same view. Now this is the plane under consideration. I need to resolve the forces, same plane. But I need to show it in the 2D view. Let us show it in the 2D view. BD represents the force P. I need to resolve this force. The pressure angle is alpha, PS is the separating force and Pt is the tangential force. In this triangle BCd, BCd, then alpha is BC by CD or it is PS upon Pt and therefore I can get the equation as PS equals Pt tan alpha. PS is perpendicular to the pitch line OD. PS, this is the separating force. PS acting along AD, it is perpendicular to OD. Now let us consider the plane which is shown by red color. I can see that this is the plane. Let us consider its 2D view. Here I can say that force PS is acting along this AD. This angle is gamma. This force I need to resolve into two components. One is radial which is directed towards the center and PA is the axial force which is along the axis of the shaft of the gear. The angle between lines OD and OX, line OD and line OX is gamma, this angle. Therefore the angle between lines AD and FD, AD and FD is equal to the pitch angle gamma. You can think upon why this angle equals gamma. I can establish the relations. This is PS. Its adjacent component is cos component which is radial force. Therefore PR equals Pt tan alpha cos gamma. It is the cos component of the force. The sine component will be equal to PA, this force. And hence PA equals Pt tan alpha sine gamma. We know that Pt equals MT upon RM, where RM is the mean radius. RT is the torque transmitted by the gears. We need to now check what is the mean radius. RM equals DP by 2. What is DP by 2? It is the pitch diameter. This DP by 2 is the radius minus B sine gamma as this is inclined. I need to find out this particular point and hence I need to reduce the distance, the radial distance. I need to find out this difference. Therefore RM equals DP by 2 minus B sine gamma by 2, where B is the face width of the tooth in millimeter. Now the Bevel gear and pinion forces. The radial component of the gear is equal to the axial component on the pinion. This is very important. Radial component of the gear is equal to the axial component on the pinion. The axial component on the gear is also equal to the radial component PR on the pinion. Let us see the 2D views, pinion and the gear. It is the mean radius. Mean radius is also over here. Angle gamma corresponding angle will be over here. This is the pitch point shown on the pinion. This is the pitch point shown on the gear. There is no issue about the tangential force, but the force exists PS, it is a separating force. Why it is called as separating? Here we can understand that this force tries to separate the pinion and the gear and we need to prevent it. Therefore the mounting methods of the Bevel gears have come in picture. However right now we are going to consider only the resolution of forces. Now this PS we have considered it is a separating force and hence we need to analyze this force separately PS. If I check over here the forces how these are shown PR and PA are the outcomes of PS, which are the forces first one is PN or P which is the normal force or the resultant force acting on the tooth. It has to be resolved into 2 components which we have resolved as PS and PT. But for our understanding we need to find out axial force and radial force and hence we have established PA and PR. Axial force on the pinion is parallel to the axis of the pinion. Radial force on the pinion is perpendicular to the axis of the pinion. Correspondingly if I consider this gear the radial force on the gear is acting perpendicular to the axis of the gear and axial force on the gear is acting parallel to the axis of the gear. As per these 2 statements first one and second one PR on pinion the radial force on the pinion I am talking about this force is equal to the axial force on the gear these need to keep each other in equilibrium. The other force axial force on the pinion I am talking about this force and radial force on the gear this force these 2 are equal and keeps each other in equilibrium these are mutually opposite in direction PT of pinion is equal to PT of gear.


Okay, so as I, I will repeat the protocols. First of all, do not rush through the questions. They are, they may not be straightforward. Then there would be some traps laid in the questions and the options. So hence, okay, so here we go. Five, four, three, two, one, stop. First question on the screen, read carefully. And then, okay, based on identities. Don't really, you don't need to click the answer somehow. Okay, mark the answer, no need. Solve and then mark. Take time, no worries, but make sure that today, whatever number of questions you do, you do it correctly, all of them. Mark at the last moment, that's acceptable, but don't mark it wrong. So the question says X plus Y is four and X dot Y, X dot Y is multiplication. X times Y is minus two. Then find the value of X square minus Y square. Take your time.  Okay, mark, very good. Calculations, no, why you should guess. Don't guess. No, no guesswork. No clue, oh my God. Questions will be tough today. So please be, please be careful, okay? Okay, fair enough. So this was the question and it was fairly simple, fairly simple. I don't know why. The moment you have, you should have seen this X square minus Y square. Move around, okay, done. Now, X square, oh, wait. Yeah, so X square minus Y square. Eight root three, eight root six is the answer. X square minus Y square. Oh, I didn't show you the answer. This is the, oh, sorry. This is the answer. Most of you have got it wrong. Okay, so let me solve it. So X square minus Y square is how much? Simply X minus Y and X plus Y. Identity, you only wanted identity. So here is the identity. Okay, next. X plus Y is anyways given, right? This value is four, no problem. You just wanted to find out, you needed to find out X minus Y and what is X minus X plus Y is equal to four. X square plus Y square plus two X Y is equal to 16, correct? Correct. So that means X square plus Y square is equal to 16 minus two X Y, which is 16 minus two times minus two, which is 20. So X square plus Y square is 20. So X square plus Y square minus two X Y will be equal to 20 minus two X Y, yes or no, right? So hence, I'm writing it here now. So this becomes X minus Y whole square is equal to 20 and minus two X Y was plus four, correct? So this is 24, right? So X minus Y will be ideally plus minus root 24, which is plus minus two root six, correct? So there was no minus sign here. So hence, X minus Y is two root six. X plus Y is four. So what is X square minus Y square? Four into two root six, eight root six, clear? Anyone didn't understand this part, okay? Yeah, wait, wait, wait a minute about again, you guys are missing the point. Why most of you could not solve is a point of concern, right? That means this is not flowing very, you know, clearly in your mind. Time was less. No, I don't think so. I don't think so. That means strategy was not there. You should have started from here. X minus Y, X plus Y, it's gone. So while solving faster, you need to find out X minus Y. In class also, we have done how to go from X plus Y to X minus Y. No, I had given you 100 seconds, nevermind. So please be careful, questions will be like that. See, was there, we didn't know in this, was there anything in this that we had? Did we bring something from our college or something? I already heard this first in the world. But I was, I'm not happy. Most of you have got it wrong. But many people have got it right. You're so good at it, you've got it right. Your voice is breaking. Sorry? Your voice is breaking. Is it fine now? Is it okay? The giant's mic is on, giant's mic is on. Is it fine guys? Hello? Sir? Who's this? Kanya. Sir, you did some step on X square plus Y square minus 2XY equals to 20 minus 2XY. Yes. So why was that? See, the idea was that I already got X square plus Y square, right? X square plus Y square was how much? X square plus 20. 20. I wanted X minus Y, right? Yes. So I can definitely find X minus Y whole square. What is X minus Y whole square? X square plus Y square minus 2XY.  That means X minus Y root square is 24. Okay, sir. Okay, sir. Got it. Got it. It's 24. Okay, questions will be on similar lines. Do not expect a very straightforward, formula-based questions. Sentom Rs will not be meant for that. You have to put your brain in maths, okay? So no mechanical questions. Okay, so let's go to the next one. Be ready. Have your pencil and paper. Need piece of paper. Start and do methodically. 100 seconds are more than enough. Here is the next question. Don't guess. Everything is related to identities. You have to manipulate. Learn manipulating. Learn observing. Hints are there in the question itself. The coefficients are the biggest hints in identity problems. Learn to observe coefficients closely and then utilize the information. Take time. No problem. So the files are there.  No problem. Just mark your answers. Okay? So last 10 seconds, guys. Not sure. Okay, here is... Time's up. Let's see the leader. I'm not very happy. Lots of people are still not able to get the answer. How many of you? Problem, how many? How many, how many, how many? X, X, X, X, X, X. Okay, lots of people are saying X. Oh my God. This could not be simpler than this. So hence, what is the learning observation? Observation is minus 4. Observation is X square. Observation is minus 4 X. Where do you see all of that? Okay, so this question was very, very simple. No audio. Can you see? Can you listen to me? Hello? Anush, just log out and re-log in. Oh, I don't know. I just sent that message over there because you can't listen to me. Anyways, so there you go. Just a simple manipulation would have worked. I hope you have not squared X then multiplied by 4 and then added 1. How many of you did that? This was not necessary. So don't do that. What you need to do is X minus 2 is root 3 and game over. This manipulation was required, that's it. Okay, and then simply square both sides. Okay, why do I square it? Because I'm getting this feel that, hey, there is an X square and then there is a minus 4 X as well. So this is X square minus 4 X plus 4 is equal to 3. Correct. And hence, X square minus 4 X plus 4 minus 3 is 0. Right? So this is X square minus 4 X plus 1 is 0. How many steps? How many steps? You could have done this in your mind. Right? Isn't it? So what is the learning? Math is all about observations. How much observant you are and can you recognize the pattern? This is the whole game throughout your mathematical career. Okay? Time... Come on. 100 seconds, yeah, come on. You know, 100 seconds is more than enough for any this thing. So you are now gearing up for a bigger platform. So don't expect more time. It will be lesser later on. I'm going to reduce the time later on. There must be some pressure on your mind. Okay? So here is the leaderboard. So please get accustomed to 100 seconds as much as fast as possible. It's sooner going to be 90 seconds, then 80 seconds, then 70 seconds and finally it will end up at 60 seconds. Fastest mathematics. You must be very, very comfortable with that. Okay, good. Good. Let's go to next question. Okay? Here is the next question. No one will crack under pressure. You guys are much better place than probably we and your parents' generation. So don't talk about that pressure at all. There's no pressure. Careful. This can be done in mind, but careful. Again, use of identities and manipulation. These manipulations will be required later on when we are going to discuss trigonometry. So this question is inspired from trigonometric identities. But it is very much within the ambit of algebraic identities. Why were traps ever invented? Were traps invented or they were discovered? Question mark. Was mathematics discovered or invented? Million-dollar question. Maths was discovered or maths was invented? There is no gut feeling maths. Okay? Maths was found. Math was found. Okay, cool. So, done. Time's up. Very good. Still, people are... Oh, no. Today the correct percentage is down. You need to work hard more on identities. It was as as I mentioned earlier, you need to work hard more on identities.  So this was the question and what was it? It is simply if you cross multiply, take this thing up and multiply with this. Okay, so it is a square minus b square is equal to step number one. Count the steps guys. All the questions will be solved in three steps. That's the fun part of it. x a square minus b square is one a square minus one is b squared step number two, right? a minus one a plus one is b squared that means that means this is b into b, right? Okay?  Got it? Got it? Did we use something out of the world boss? So easy. But I don't say that. See, I am not trying to see these are first of all, please understand this. These are level up questions. So you guys are anyways daring enough to get into the woods without, you know, knowing much about it. So I really appreciate all of you for this. So my intention is nowhere to break your this thing, okay? Confidence. So don't say that. Then my purpose gets defeated. So these sessions are for you to expose to level up. I never judge anyone, guys. Please understand. You know, you guys are daring enough. I was so fissured. I could not ever, you know, I could not have ever sat for these kind of sessions. Forget about solving. So hence, you guys are anyways ahead. But what I am trying to tell you is these are level up questions. So hence, see, I have put in a lot of effort to fabricate them. I am not copy pasted from somewhere. Because this is what I want to introduce you to. Please understand this. So slowly and slowly, with time you will all get to that level. Okay? So hence, what learning please focus on learning. Learning is there is nothing hard in it. Was there anything hard in it? Tell me honestly, was anything which is very, very, you know, out of the world? Was it so hard question? Once you know this is just a manipulation game over. So hence, this will happen multiple number of times. It's better to be prepared than to be sorry. Okay? Let's move ahead and let's see who did well in this question. So there are only 20 people who got it correct. Right? So slowly and slowly you will it will become part of your life and then it becomes easy. So don't worry.  Okay? These are okay. So Anvi is on the first rank right now. Okay. Let's go to the next question. Put some thinking behind the questions. It is related to only identities. Only identities now here. But it will not be a straight forward. It will ask you some multiple aspects of it. Yes. Solve this again and it's getting so this one isn't this one is an easy one warming up question so that you are someone said I am breaking his confidence or her confidence that was like the purpose getting defeated.  All of you can solve these. There is no intention of showing you down. Okay? So hence, please understand slowly and slowly you will come up to that level. You it's on the individual to decide whether someone was something was warming up or not. Why warm up in the middle? Because I change the question just now. Okay? Very straight forward Ashish don't write the you know don't discuss the options here. Okay anyways this was fairly simple. Most of you have got it but still only 50%. Okay? So this was again very simple very very simple question. So again it is of the form of A minus B times A plus B So what is it? A square minus B squared right? Then hence it is 10 to the power 6 squared so whatever you learned in the previous chapters should not be forgotten. So hence right? So hence it is 10 to the power 12 minus 10 to the power 10. Okay? So this is if you take 10 to the power 10 common what is left? 10 square minus 1 right? Is this clear to everyone? Right? So hence this one is 99 into 10 to the power 10. Okay? So what is the answer? 99. Okay? Clear? Let's see. So all top 10 people are continuously performing well good? Very good. Let's go to the next question again it's application of identities I have just written it in a different ugly looking fashion. That's it. When on a battlefield the bullet can come from any side so hence you must not be prepared for only one direction warfare alertness all around. You shooting the bullets will not impact much no Vishak you are receiving bullets at the same time so you must be alerted from whichever end, whichever direction it can come. So you should be prepared for any exigency. So you should be able to look things from different perspective right? You should be able to look at things from different different angles. That's exactly what this question is doing. So they will not be direct. They will ask you to go beyond a point. Okay? So again this was very very simple question in three steps it can be solved none of the questions are okay. Most of you have got it but again 50% only so here is the question which identity? Trinomial square why? a plus one sorry a plus one minus b is zero this is what you have to write. That's it and done. Then what you need to do is square both sides right? So hence a square plus one plus b square then plus 2a then minus 2b and minus 2ab this is zero isn't it? This is a plus b plus c whole square now over game is over here itself. In one step you could have written it minus 2b is equal to 2ab minus one right? Was it difficult? How many of you think it is difficult? Right? Is it difficult? Was it difficult question? See observation okay. How do we figure out that we have to do this? The catch was these two terms right? and so hence the moment you saw that and there are 2a and 2b and 2ab times are missing. So that was when it would have like that. Trinomial formula yes why not Trinomial formula is this a plus b plus c whole square I asked you to compile all of this and keep it whenever you are solving questions correct? This one was the trinomial formula but then here one it was a minus b plus 1 whole square right? Is this clear to everyone any doubt in this question? Below nothing beyond 3 steps get the maths in 3 steps is the no no one is done don't say such words if you curse yourself that means you are indirectly cursing the teacher who is teaching all of you that means you are cursing me my students cannot be done okay next now conventional questions simple easy get some points there will be mix of easy and difficult question okay very good not recording of the speed it's all there on the recording of this thing no okay come on come on very good 10 9 8 second left okay cool oh no still we are not crossing 50% today what's happening I have to do something now some more effort maybe okay why were you struggling in such questions anyone lots of you cannot do it so again whenever you get such kind of questions you know the conventional methodology is squaring right squire you will get 4 right so this is x square plus 1 by x square right plus 2 because x and 1 by x will get right so this is 4 so this 2 comes here it makes it 2 right right then what x square plus 1 by x square minus 2 is 0 and game over here itself game over right so x minus 1 by x whole square root 0 is 0 got it right x minus 1 by x is 0 so should not have faced any again see how many steps 1 2 3 right none of the questions will require more than 3 steps next oh there is shuffling happening cool and we again back identities may learning is you need to some more time never mind we will write some tests shall next question focus go by elimination eliminate elimination was the best way here hmm wonderful ok here hmm oh better performance this time what happened this was fairly again very very simple questions I don't know why are you AB what was AB in such questions breakdown into 2 parts so first part is AB right so what is AB AB is simply XY and x plus y into x minus y is x square minus y square no problem first step done A plus B let's write A plus B ok so x by x minus plus y by x minus y right common denominator what happened what c c means what what happened any any problem so this is common denominator is again x plus y times x minus y and here oh c for clear ok c so hence it is x square minus x y so this will multiply like that and this will multiply like that so this is again plus x y plus y square so this minus x y plus x y is good right so this is x square plus y square and in the denominator x square minus y square the question was AB by A plus B so AB is x y upon x square plus y square divided by x square plus y I'm sorry minus it was minus here isn't it so this this is gone so what is left x y upon correct any problem in this correct all of you yep good very good so hence let's go to leader assia board assia ok so here is the leader board and we is saying ok there is some shuffle very good now next conventional problem training zz zz zz z easier zz zz zz zz zz zz zz zz oh my god so many z's sir solve easiest one so far is it easiest one oh my god increase the bad feeling don't have bad feelings for anything yes now ok cool nice looking graph I hope our corona graph is like this only going down ok right now let's solve this was the question fairly simple again in such questions wherever a square b square and a b is given right what do you do add to a b subtract to a b ok now so a square plus b square minus 2 a b will be how much 1 1 7 minus 2 into 54 isn't it this will leave it as 9 that means a minus b whole square is 9 right that means a minus minus 3 right now what about a plus b so a square plus b square plus 2 a b you will get 1 1 7 plus again 2 into 54 which is 225 so a plus b whole square is 15 square so a plus b is plus minus 15 now you have to find out a minus b by a plus b so no negative has been given in the question so hence you take the positive once so plus 3 divided by plus 15 a minus b a plus b what is the learning if a square plus b square is given and a b is given always go for a plus b whole square and a minus b whole square correct 3 4 ok very good tambourine gang what is this why do you have gangs and all my god floor gang roof gang no one will fail don't fear when I am here ok again intentional question if you fail I fail and I generally don't fail none of you will fail none of you will fail because I don't fail so hence you will not fail henceforth you will not be I don't worry I have supernatural powers also so all all my students cannot fail guaranteed no problem I'll solve questions are very easy yes I know they are easy ok here is the so 25 people still got it nice these are very conventional problems I didn't want to put them but then I knew that you will be facing some trouble here again first thing what I did was the position usually you will say this kind of a thing so just to break that right these things I just swap the places so a square plus 1 by a square is 7 you know whenever a square plus 1 by a square is given what do we need to do a square ok go like this you want to find this out right 1 by a cube plus a cube what is this is of the form of x cube plus y cube what is the formula x plus y x square plus y square minus xy right this is the thing ok now then what is this x plus y x plus y here it is a plus 1 by a and you will need a square plus 1 by a square minus a times 1 by a correct right so 1 a plus 1 by a you need and a square plus 1 by a square you need a square plus 1 by a square already given so within this bracket this is 7 minus 1 half the problem solved you just want a plus 1 by a ok so what is a plus 1 by a a square plus 1 by a square is equal to 7 then if I add 2 to both sides I will get 9 and this will become a plus 1 upon a whole square is 9 so a plus 1 by a is plus minus 3 did you understand once again I will repeat you have to find out a cube plus 1 by a cube ok this is a cube plus 1 by a cube now x cube plus y cube what is the formula x plus y so a plus 1 by a and within brackets x square plus 1 by sorry why am I writing x square I have to write a square plus 1 by a square minus a times right right this is 1 this item was already given in your question see a square plus 1 by a square is how much 7 you don't need anything here so this bracket is 7 minus 1 correct you just needed to find out a plus 1 by a and then it's done how to find that out it was given a square plus 1 by a square is 7 ok now add 2 to both sides no problem ok so this becomes a square plus 1 by a square plus 2 times a times 1 by a 2 can be written like that and this is 9 so hence it is a plus 1 by a whole squared so a plus 1 by a is plus minus 3 that means this 3 and this becomes 3 into below difficult but learning in this question is please for God's sake I had given you this from x plus 1 by x I did in the class also converted into x square plus 1 by x square converted into x minus 1 by x converted into x cube plus 1 by x cube converted into x cube minus 1 by x cube did I not discuss this these forms right so just you have to remember also and repeat repetition is the best way done so next question need a board ok some changes very good nice very good shall let's go to the next question slow and steady wins the race I was a drummer in my college dude yes once upon a time I wanted to end up being a musician but destiny had something else for me ok fingers crossed observation will be key here yes I will solve I will solve I hope people have seen the trap there are the trap in this question tan tan tan tan wah that's amazing I hope I know you would not have seen the trap there was no this question is wrong this question itself is wrong why there is some issue in this question what was that wait a minute is it wrong hold on x is equal hold on hold on hold on yeah yes yes yes it's cube so the option was not there I will delete this from the backdrop so this question what had some issue wait where do I go I have to go to mentee just a minute give me a moment I will just a minute so that it is yes I will explain the question don't worry but let me one minute do mentee ok so one minute one minute your presentations I messed up with the x over there hence never mind so yeah I will explain don't worry explanation is spending I have not still not done it I will first remove the leaderboard this was question number 10 question number 10 hey don't whistle not appropriate question number 11 not number 10 ok so I am deleting question number 10 done now so I have eliminated question number 10 so let's go back to our presentation let's go back to sharing the screen screen started yeah can you see the screen now screen visible yeah so I have oh this so what you can do is so we can't see the screen all of oh you can't see the screen oh sorry why now visible so all of you simply mark D mark D D D quick mark the answer D D D D D ok all done why did you give you a right answer I had reset the leaderboard and then ask no problem here hardly I am chalo one question here and there will not make much of a difference right now so all of you mark D ok so I will move ahead oh there are 55 56 come on everybody ok ok ok done anyways so it should be X I had to write X cube I had written X 1 by 3 actually so that was wrong anyways so oh still people marked C and all never mind there go the explanation to this is give me a moment where is it why it is not coming just a minute ok so this was again very very simple why because you have to observe this that A plus B plus C is 4 I had purposefully written it like that and A B plus B C plus C A is 6 ok right and now it was very simple A cube plus B cube plus C cube minus 3 A B C is B plus C A square plus B square plus C square minus A B minus B C minus C A this is the formula this is the identity right so hence A plus B plus C you already know it is 4 A B plus B C plus C A is already known 6 you just needed to find out A square plus B square plus C square how to find that out simply square this one A plus B plus C is 4 so squaring both sides will get you 16 so this formula we learned previously A square plus B square plus C square plus 2 A B plus B C plus C A this is 16 no no no you don't require to start video ok so now A square plus B square plus C square will be how much 16 minus twice A B so this I am writing here A square plus B square plus C square plus 2 times A B plus B C plus C A is how much 6 is 16 so you got A square plus B square plus C square is 16 minus 12 which is 4 right so this is 4 ok now what all you now know this is 4 within bracket this is 4 and what is this minus 6 ok hence it is 4 into minus 2 which is minus 8 correct yes this is X so it was given that X to the power 1 by 3 is minus 8 so X should have been minus 8 Q that means 256 negative is it not 8 sorry what will this will be 9 no so 512 minus 512 like that so this should be the answer actually while framing it I wanted this to be X here and 1 by 3 was supposed to be here but I by mistake interchanged it anyways ok let's go to the next question here is the next question no no no no it's minus 512 it was missing correct the option was missing ok next question come on let me see how many of you can do this pizza party no problem Biba no problem simple one again ok come on downfall and why god big words Pranav where will you fall on the ground only I can never fall ok very good very good very good oh my god I was thinking that D was the answer still many people got it wrong one more question ok yes so A plus B plus C is 0 that means A plus B is minus C B plus C is minus A and C plus A is minus B and game over so this term is A square times minus A and then B square times minus B plus C square times minus C right so this is minus A cube minus B cube minus C cube that means this is minus A cube plus B cube plus C cube and we know that if A plus B plus C is 0 then A cube plus B cube plus C cube is is it right minus 3 ABC was the answer correct got it anyone didn't understand once again explanation good what happened Monisha any problem keep it on screen ok Monisha can we proceed ok last question of the evening leader board 2 only 2 people 3 people from top 10 ok very good and we still maintaining the lead that's fine last question guys very simple very simple good night sleep after this question I will repeat explanation after this don't worry those who want any explanation to any of the questions please stay back will repeat don't use calculators not needed I hope I am right don't stay awake till 12 o'clock not good if anyone wants me to wake you up let me know I have a software for waking people up here is the cool still 26 people got it right that's nice and I think you guys fell for the trap those who have so 16 there was a 2 here I hope you saw that 2 right so this is right otherwise it was very simple question so this is a cube plus b cube plus c cube minus 3 a b c divided by a square plus b square plus c square minus a b minus b c minus c a this was leading right so hence this is a plus b plus c isn't it a plus b right so a plus b plus c is 2 but there was a minus 2 also so 2 minus 2 is 0 answer was a ok so there was a in the last question sorry if you if I hurt your sentiments but then that's how life is you will have to get trained for all of that and the final leaderboard is this so this is the final one see who came on ok so Anvi maintained the lead till last very good congratulations but then I see lots of people who were last time were are not there very good Anvi from Rajasnagar is 7976 points very good very good very good then Anirudh Akshay Karun Ishika so these are the people we have already done till what polynomial didn't understand someone said something Jagarap Singh said that we have already done till polynomial but in school we will again start from number system what is the point good revision no but hey guys my request to all of you please do not disturb me just because I have got a feedback from previous batches that once you know stuff you actually you know so just observe in the class don't go all out and solve all the problems and ok so please just be grounded you don't know anything right now maintain that ok bye bye guys take care see you again on Saturday be prepared for the next quiz on remaining portions of whatever geography is there and we will start physics mostly this week onwards yep bye bye take care and enjoy your school all the best for a great year ahead from tomorrow bye bye take care I will repeat this those who want to stay back for the explanation please stay back here is the explanation this was the this one right question number 11 explanation who wanted yes yes ok a 0 a plus b plus c is 0 and you have to find out value of a square b plus c b square c plus a c square a plus b cyclical expression this is called cyclical so a is replaced by b b is replaced by b then b is replaced by c c is replaced by a a is replaced by b like that cyclical right in such cases so what do I do from here if I see a plus b is equal to minus c or not first ok then similarly b plus c is equal to minus a right and c plus a is equal to minus b now a square b c b plus c is odd a square times minus a from here b plus c was minus a so this is minus a q similarly b square c plus a will be minus b q and c square a plus b will be minus c q correct so you have to add all of them so adding all of them ooh there was some explosion by locality anyway so a q b q plus c q correct see one got it yep and now we had a conditional identity we learned what was the conditional identity if you remember if a plus b plus c is 0 then a q plus b q plus c q is how much is it clear so can't I replace this a q plus b q plus c q by 3 a b c so then it is minus oh is it now it is clear clear anyone else wants any other explanation please tell me sorry for that yeah can I do any shall I clear this off so that you can understand this properly for explanation I had done that okay is it okay understood okay buddies bye bye and enjoy your first day that's cool see you all got this no miscellaneous quiz let me see if I will I will give you two days notice if I am done with the preparation of the questions then we can do okay I'll tell you okay do you like more miscellaneous quiz huh bye see you


Associated and stagmus are not localizing. They usually are seen in disorders affecting the posterior fossa, multiple sclerosis, for example. Note how each eye is doing different movements at the same time. Most of the movements are pendular, but the direction and the frequency are different between the two eyes. In this patient, a relative null point is seen in left gaze.


Wonderful. Okay. You should all see my screen. All right. Well, I am reporting live from Paris, France, where I am happily Working remotely here for the next for this whole month of March and it's been great. I've just had Lots of opportunities to connect with the European community I've already gone to Drupal Camp London and spoke there at the CXO event and then I went to the German splash awards where they were celebrating some really amazing case studies that were created for German clients and I'm getting ready to have a dinner with the French Drupal Association next week and then go up to the Netherlands and Participate in their splash awards. So it's just been a really great month and I eat in a clear Chocolat every day So that is my that's my personal KPI So before we begin, I just want to do a little housekeeping I asked that you just remain muted But if you do have a question we want to hear from you and you can post it anytime in the chat window Tim's going to help me monitor that. You hear something you like? Feel free to do a screenshot or tweet something out. Use the handle at Drupal Associates and Our agendas will just highlight some key news happening here at the Drupal Association Then go into our two main programs DrupalCon and Drupal.org and give you some updates And I've asked Tim London to join me so he can as director of engineering I'd like him to give you a little more insight into our work on Drupal.org So you'll hear from him after me Of course, you're all our supporters and we really need your support for funding Drupal.org Which is the community home and lots of great things are happening there. So we can't thank you enough For deciding to give back to the project in this way It really means a lot and it clearly takes a lot of you to help us fund Drupal.org and so We try to provide the most value we can with this program But we recognize that this was a choice that you made to help us fund the infrastructure So thank you very much for your support And now let's head on into Drupal Association news You might have seen my very long blog post Which is about our 2018 execution plans and I like to just walk through that very briefly and give you the highlights But again, you can go on Drupal.org Association slash blog to find the longer Post that gives more detail about our 2018 execution plan It also includes a dashboard of all of our projects with milestone and metrics and we'll be reporting out on that throughout the year The most important thing about our execution plan is that our primary goal is to help grow adoption of Drupal 8 In our channels Drupal Drupal con and Drupal.org this big Effort throughout the project to grow adoption in lots of different ways And of course we want to pull our weight in the areas that we can which are those through those two programs And so as we were thinking about our work. We had some imperatives one was To grow adoption The association really needs to expand the personas that we serve. We've primarily been Serving the builders and the builders who contribute back to the project and that can't stop We just need to do more Because digital experiences require not just the builders, but the people that are deciding If they should use Drupal or not there It also includes all the marketing people who use this the platform to get a business Result and so we need to talk with them as well And we also need to talk with marketing because we're seeing that Budgets that have been swinging and more CMOs are making technology buys So this is one area that we're focusing on as we think about our work is how do we talk to all these personas and help them Choose Drupal and help them be power users of Drupal And then of course, how do we help them find their own path into the community where they can contribute in their own unique way? The other imperative is that we want to make it easier to choose Drupal So whether you're on Drupal org or Drupal con How can we make it easier for someone to come to the site or come to the event and Say, oh, I'm getting the information I need and I want to move forward with my evaluation path I want to choose Drupal a lot of effort into that and We also want to make sure that Drupal is as competitive as possible in areas that we can help is Many ways to reduce total cost of ownership. We have that as one area that we can prove And so we're looking at auto updates and I'll talk some more about that That's really to help the mid-market and then also ease of use We know a lot of people are not using composer And the command line to build Drupal And so we are going to build a tool for site builders so that we can help them use Drupal 8 in a way That's kind of more aligned with how they are used to working with Drupal So our focus areas we have four one is to accelerate the adoption journey want to inspire and inform evaluators Starting to really amplify and get people excited about what Drupal's done for all kinds of great names out there We want to help create these resources that an evaluator needs so that they can be converted into users And again as I mentioned we want to improve the product where we can In those areas that I mentioned the other focus area is we want to strengthen the user journey And so this is really about helping people keep falling in love with Drupal helping Agencies like you have customers who you know retain your customers So they keep using Drupal The third area is supporting community health and there's lots of ways that we can do that but it's mostly Really expanding how we serve and who we serve so that it's more global and has more personas And we just have a stronger relationship with the community both You know bridging the gap between Drees by Tardt in the community and creating more opportunities for discussion as well as The Drupal association in the community And then last and we just want to build a stronger foundation of support for the Drupal association Of course, we want to make sure we have happy staff and They love working here and in serving the mission But we also are going to focus on organizational and financial health Because obviously as we need to stay sustainable to keep our community support sustainable Uh, and again just getting more ambassadors out there for Drupal and the Drupal association So those are the four areas and here's a real simple heat map Kind of look at the whole life cycle You have the adoption part of the life cycle Then they turn into users and they become community members and I look at these three segments and You can see we're putting a lot of effort on the adoption side a little bit on the user side And uh second priority is the community side Um Primarily because we have some catching up to do on the adoption side Does not mean we're going to be reducing anything we do for the community So let me just go through quickly some highlights of how we're going to be Serving each of these three areas For our current customers Of course, we'll have Drupal con and that really is a user event and a community contributor event It's really you know, if you look at all the sessions there, it's really to help you be a power user and So, you know that that doesn't stop But one thing that's new is we want to know who our customers are There's a lot that we can um a lot of insight we can gain if we know who our customers are What modules they're using Etc etc and today the Drupal association is not part of the sales process So we don't know however every website is coming to Drupal.org and by working with Drupal core we can Add some telemetry to Drupal 8 to Drupal core and be able to capture some information that can give us this insight And then we want to work with the community in some new ways Um, so I've talked about how we want to work with the community on product improvement One is the auto updates initiative Um, you know when I talk with companies in the mid market, especially those that decided not to stay with Drupal they say it's a lot of it's because talent's expensive and having talent doing manual updates is an expensive cost and The mid market would really benefit from auto updates. And so the Drupal association is going to work with Drupal core and other community members in order to Start this initiative up and then also just a real fast not fast but a great way to Grow Drupal adoption for Drupal 8 is to make it easier for site builders to use Drupal 8 Especially those that aren't using the command line for buildings So that's why we'll have that tool for site builders that I mentioned before We are also going to start having some round table starting at triple con nashville and one will be a customer round table Um, then I wanted to call this one out specifically. We as the association again We don't have that relationship with customers and we want them to be part of our community too So we've been reaching out to you as supporters to see if you have any customers They would like to spend two hours with us getting to know each other But also getting to understand like what can we do? As a group to help customers become part of the community and see how they can invest in Drupal's longevity in a way that benefits their business So that's the conversation we like to have and it will just be a peer-to-peer networking discussion And I hope it's the start of something much bigger In some other areas that we're focusing on is recognizing and rewarding community So we know that nothing gets done without all of our volunteers and people do their volunteer work for many reasons and one of them is for Social capital right and just really being known and seen as someone who's stepping up and leading and they just want to You know, sometimes just a thank you really matters And so we have the contribution credit system that right now gives you credit if you submit a Well code of course, but uh, Drupal 8 case study or if you're a supporting partner uh, but we want to expand that to um Another area which are camp organizers, you know, as you probably know camps are Little marketing machines all over the world that are attracting developers and also onboarding people to be contributors It's a great meeting place for companies to start to decide kind of at the ground level if they want to use Drupal And uh, it takes a lot of work to organize a camp Or really any kind of community event. So we want to start Recognizing them and the teams putting some efforts in place to be able to do that Um, and we're also looking to keep enabling the community last year Tim and his team did a lot of work to assess Developer tools like get lab and get hub And we had to put that on hold because we just found that it wasn't getting The features just weren't where the community needed them to be so we weren't ready to migrate But we're still exploring it as these tools evolve So I want to let you know we did not forget that and we also hear a lot of interest in finding a way to fund project maintainers and You know camps want fiscal sponsorship And right now the da can provide it for some camps, but we have some limitations. So we're looking to scale more globally and We think a partnership with open collective could address some of these needs and allow people to collect money and Spend that money as they need to in a very transparent and compliant way. And so we're exploring that partnership And then on the adoption side This is really about getting those decision makers to say yes to Drupal And again, since we haven't been part of the sales cycle For us to do a great job in our channels Talking to these to this audience. We want to first understand them. So we're doing user research right now Very thankful for our board member annie miller Who's taking the time to do these interviews and she's talking to personas throughout the entire life cycle um to really understand What they think and what they feel and what they need in order to say yes I want to go to the next step. So really excited to start pulling that information together and having it kind of drive the evolution of our programs um and You know, there's I'll go into more detail, but again, I mentioned how we want to inspire and form these decision makers And really get them to move through the evaluation process quickly and really frankly connect them to you We're not going to be able to sell them on Drupal And help build them anything The most important thing is to have a conversion where they talk with you as trusted agencies who can deliver something really powerful for them And then the last area is that Drupal Association support. So we've set up our KPIs from a financial perspective. We are doing um better with our financial turnaround and we have Getting ready to put out some blog posts about that for 2017 The results were really positive and we hit our goals that show us that we are Moving through that financial turnaround and becoming much more sustainable Which means the project's becoming more sustainable, which is wonderful. And this year is going to be another important year for us So I'd say that we're not a hundred percent done with um this turnaround But we are starting to walk out of those woods and we will be doing it with you and your support. So thank you I definitely envision us doing a fundraising campaign this year to accelerate adoption. Um I'm seeing a lot of needs. I need to work with The team and the community to scope that out whether it is crowdsourcing funds to Kill bugs to help people migrate from Drupal 7 to Drupal 8 or might be helping with documentation Or it could be about crowdsourcing or getting some extra marketing power to do some PR So I'm just seeing a lot of things I just need to work with the community to prioritize that and then launch a fundraising campaign so we can execute And as you know, we want to keep building strong relationship with the community And we're just really thrilled to have Rachel Lawson on staff as our community liaison And she is already starting to build a stronger relationship with the community. She's out there engaging with the community You see her online answering questions and she'll be doing a lot at Drupal kind Nashville And uh going to BOFs and these special round tables and facilitating them So hopefully this kind of work um in the different regions will make a real difference in building an ambassador ship for the association And then just another area to point out is we always need to worry about compliance risk And so uh, we're working for Drupal dot org subsites to be GDP are ready Uh, and right now we're working on all of our commerce sites being PCI compliant So those are important things just want to let you know we've got our eye on the right stuff All right, and if there's not any questions that I'll keep going Another announcement from the Drupal Association is that we uh have new board members Terms are every three years if you're nominated if you're elected it's every two years and We actually expanded the number of people on the board and allows us to have more diversity Specifically regional diversity as well as diversity of perspectives of different stakeholder perspectives on the board Um, so we have adam goodman. Who's our chair? Um, he is going to be with us through 2019. He's taking a seat that's a little truncated.  It's kind of taking it up a notch in strategic planning um as well as a board that doesn't have The founder of the project as the chair and there's some just some changes that needed to happen around that And so he's just advising and helping us put the right infrastructure in place for that Dries of course is still on the board But is in his founding director role which gets renewed every year The other board members are george matthas Who is from uh johnson and johnson? adre martin marrick, um is in scotland and she Is a customer experience advisor has worked for companies like the economist batty bridart, sorry that got truncated there um She is in germany and runs a digital agency there and ingo rub is in germany as well He uh is now the ceo of a startup But he was recently up until recently the cto of bird of media Many people know him as the person behind the thunder distribution And michael van veld is a digital agency owner out of the netherlands um as you'll see we have lots of different kind of stakeholder interests represented here But really uh, it's very heavily skewed to europe We felt that we really needed to have more of a european voice on the board And so we're just really excited to have them there All right, let's go into some updates about programs starting with drupal con. We're really excited It's going to be here in less than a month, which is crazy But everything's coming together really nicely. Um, we just put out the new schedule. So go ahead and start making your plans One thing that you'll notice on the website. That's news. We have wide drupal con We wanted to make sure that as we Have all this content for different personas that it's easy to find Uh, so you can go to wide drupal con and start seeing what I call recipes Um for different personas. So you can get um ideas of what to do for if you're an organization leader Give you your director of engineering at triple a Uh digital teams. So whether it's digital teams at an agency or at an end user There's all kinds of content for you um this year we have um content specifically for content editors training lab sessions So please make sure anyone you know is a content editor Make sure they know this is available to them. We really want to get them there And then uh, of course, this will probably be the most interesting to you, but digital agencies We have lots of content to help you as a digital agency, whether it's the business track or the business summit or um different case studies to inspire you and also some really great talks about um What's happening in the marketplace? So um Check that one out for sure And then of course we have others whether it's all kinds of content for building Decoupled solutions some are technical in nature. Some are talking about the the solutions that are made through decoupled Efforts and then we have all of our case studies aggregated here And then if you want to learn how to get involved with the community while at dripple con whether you're a new community member A long time community member. We've aggregated all of that information in this recipe And then for new attendees, maybe have a new employee going for the first time They should check out the new attendee page so they can see all of the great um Ways that we make it easy for someone to get involved and feel really welcome And we are promoting by personas as well. So you'll see that we're taking this content and tweeting it out Um, definitely trying to start moving into this more persona-based marketing for our event Some highlights that I thought that you as digital agency owners might want to know about are the supporter around table Uh, you should have received an email to save the date Wednesday from three to five This is a opportunity for us as the association to talk with you specifically about What are your needs? um You know, we are hearing a lot of different kinds of needs that the association might be able to help with um And um, we want to get aligned and we want to find a way that we can invest in this together Um, especially in a way that doesn't defund dripple.org But we're definitely hearing the need for some partnership here and we'd like to have that conversation with you Um, again, I mentioned the customer round table. That's tuesday from 10 30 to 12 30. It's hosted by mike lamb From fizer, um, it's director of engineering at fizer It's going to be a peer-to-peer discussion and I think it'd be really great for any customer to come to this um And start finding who their peers are and asking some of those questions that keep them up at night and being with people like mike who are True believers in dripple, um But more than anything is that chance for us to hear how we can help them and help them become part of our community Another thing that we're doing, um, thanks to donna benjamin another board member So we're going to be doing testimonial videos Um at dripple con we want to talk to everyone and get testimonial videos that can be Turn into different kinds of sizzle reel on dripple.org on dripple con Really promoting why dripple's so great or why the community's so great And we would love to find out, um, if you would like to be, um, videotaped I think videotape just aged me But if you would like that We would love to hear your story and your customer story and your staff member's story So please be in the lookout And also some it's all kinds of special events happening at dripple con But just don't forget the monday opening reception This is when we open up the sponsor like the exhibit hall on the sponsor floor and everyone can come together And there's a lot of energy there So I highly recommend you're there at your booth. Um, and then wednesday After the support around table is the vip happy hour And this is um a chance for us to say thank you and you can do some Some final networking before the end of the day. It's um a couple hours of drinks and light bites and good times All right, and then let me just go over to dripple.org and give you some sneak peeks Uh, so we are working on improving the adoption journey Starting at the front page, which is where we know evaluators are going to and this is what it looks like today You can see as all kinds of call to action and videos. This is um, thanks to aquia We're always looking for Our partner's content. We don't have a team to create content. So we're very thankful when When you can provide yours for the site to help with this evaluation path because we have news and all kinds of things on this site But we know that it can be better and a more streamlined Evaluation path. That's a lot here to choose Drupal Yeah No, this is tim I was just going to say to add on to that one of the things that you can see immediately when you look at This page is that it's oriented towards the builders of all those personas that we've talked about and not to The additional personas that are really part of our 2018 focus And so we have already done some data gathering to get some more information about who it is that comes to this front page And to understand better, um, especially the anonymous traffic, uh about who's here So if you go to the next slide, Megan um so We've done a little bit of of data gathering as I said about uh, who comes to Drupal at organ specifically who hits the front page versus the other areas of the site and um, one of the relatively interesting data points is about 14 out of 15 visitors are anonymous. They're not our authenticated users They're not our highly engaged community members. They are other people from other, uh, walks of life who are evaluating Drupal Um, and who are kind of an unheard but very large part of our community and we want to hear them better and serve them better um, so, um We've gathered some data, um using a couple of different tools about our anonymous traffic And so we understand a little bit better Who they are um, and kind of what industry they're in what uh area of expertise they're coming from and things like that So as you can see, um, this table sort of outlines, um Those anonymous visitors by their job function and give some information about the proportion of front page visitors in that job function versus all visitors So you can see for example that all visitors to the site leans heavily towards uh people who are in engineering or information technology roles But the proportion of front page visitors has actually quite a high amount of business development entrepreneurship roles marketing roles medium communication design In other words end users and personas that we haven't historically been serving Um, but who are increasingly the decision makers in choosing whether to adopt Drupal Um, so we now have some uh hard numbers and we're continuing to gather some more data on that If you go to the next slide, we have a little bit of information on the some some of the specific, uh job titles Of some of these roles, whether it's people in manager managerial roles CXO level director level In various kinds of departmental roles and things like that um If we keep going Um, so we've done some user research and these were interviews conducted Um in part by megan and part by others um on the team just talking to various people About what the experience is like coming to Drupal.org And one of the some of the consistent themes were Um, you know, we the the current front page is covered in calls to action. Um, because we have Um, you know promoting the tri Drupal program getting the code Coming to Drupal con all sorts of uh industry calls to action and There's not a certain level of consistency about who those different calls to action are for and what the right path is for Any individual evaluator who's coming to the site? We also know that there's a difference in what kind of evaluator experience these different kind of users want So the technical evaluators want the opportunity to play with Drupal marketing evaluators want value proposition and demos and and the Um, they want to be shown how Drupal will empower them to uh to fulfill the business need So in addition to this research, we did some comparative analysis of just other projects whether open source or not software programs That are out there. So for example, we have puppets front page. Um, if we go further, we have The drupal.com persona Personas listed out and more or less we we evaluated these came together had a uh an off site here in portland and um and came up with a game plan for Identifying the top three personas and how to serve them on Drupal.org So the the next slides are going to be some rough mock-ups. These are not final designs Although I'll show some design comps in a minute of some changes that are upcoming. So Among other things, um, we're changing the top navigation on Drupal.org. We're going to focus on Uh, the answering the question why Drupal by persona Um, we're going to uh, we're going to provide more pathways to the kind of information that you might need depending on your evaluator role We're going to highlight the tri drupal program up in the top navigation And we're going to change the primary call to action on the front page in some form if you go to the next slide again Megan to be Persona focused so we want people to identify themselves as you know developers or technical users or business users or marketing users or agency users And and then we can funnel them into a much more targeted path that will let them know um The the information they're really looking for to understand why they want to use Drupal um, and we've also identified some Metrics to let us know whether we consider that evaluator to have converted So for example our our conversion metrics for a developer evaluator would be Things like whether they spun up a tri drupal instance or another sandbox as we develop a further demo experiences Or whether they've simply downloaded the software For the marketers and business users whether they viewed Videos or whether they've gone to the contact page which tries to connect them with supporting partners like yourselves and for the agency users whether they've Downloaded resources that we provide like the Cxl report and other things that we gathered throughout the year To provide back out to the community and to try and help a business decide to To make its bet on Drupal So to give a little bit more color Here are some early actually, you know well designed mocks of what the the new front page experience could look like And these are still very early, but we're going to have some a much more Simple design many fewer calls to action probably fewer still than even you see here Some animation to draw the eye and draw attention And then the segmentation into the three primary Personas that we want to target So and if you go to the next slide We'll continue with the rest of the page Continuing to feature case studies Point people how to get involved in the community and provide some stats about the project So that's still very much a work in progress. This is definitely a sneak preview But we hope to be showing off more about this coming up at Nashville Um in the meantime, we've done a few small things as megan mentioned earlier Um, we put up the uh video that was generously put together by aquia to promote Drupal and some of the brands and stories and um great success stories, uh for the Drupal project um and that's been a really interesting experiment in um and putting more more sizzle on the front page as we've been saying internally and more Kind of marketing oriented material and we're going to continue experimenting with other things like that Um, I'm going to switch over now to some other initiatives not specifically related to our persona work But just related to other things we've been doing on Drupal at org. So for example, um, we are trying to be more inclusive with our sign-up process on the front page So we have provided A new field to ask people to identify with uh underrepresented communities based on their Self-assessment of whether or not they're a part of those communities to give us more information about our community and areas where which we can do better um We have also Uh worked with core as megan referred to earlier to propose four initiatives in the ideas queue And um, I'll try and be brief because megan has talked about most of these one was the automatic automatic updates initiative Initially proposed by Dries at Drupal con Vienna the site builder and project browser tool Telemetry and Drupal core to give us that information about how Drupal is actually being used And lastly a communication channel in core because again We know that 14 out of 15 Drupal.org visitors don't register for an account don't log in Um are not people who are regularly in our communication channels Even though we have such a large community and it feels like we must be talking to everyone There's actually a large number of people who we may not reach And so we want to create this channel within core to reach those those end users of Drupal who are maybe not engaged with the community yet So that's an an additional proposal as well Um In the meantime, we've been doing some things Uh, never forgetting the developer experience. Um, so Um, we've added some in-context explanation for what issue tags mean for contributors So they understand what the state of something is as core is reviewing their work Um, and we've been um working on Making Drupal.org more performant and better protected on the web. So if you go to the next slide megan, we've recently partnered Uh with perimeter x Which is a sort of bad bot protection Bad actor protection service that integrates with our cdn We actually get targeted in denial of service tax almost bimonthly So it's something that the team has been sort of dealing with in the background And i'm kind of proud to say that it has almost no visible impact on uh end users of the site And hasn't for for several years now But um, we're always trying to find ways to make that more robust To better protect the community's home and to make sure that Those people who are contributing to the projects just don't uh, aren't disrupted in their work Um, finally we've done a little bit of work. Um More work on Drupal ci and working with core Um, there's a lot of effort to make, um better tools for Uh adding javascript to uh Drupal whether that's focusing on perhaps making react a standard framework in Drupal core Or just focusing on the regular javascript Interactions that we already have So to do that to support that, um, we've had to update the testing system What we used before to test the jobs here protein drupp core was phantom j s that was deprecated by its maintainer So we've moved it to chrome web driver and supported a few new Javascript related testing suites to help Really evolve the front end and the user interaction experience of Drupal and work with core to move in that direction as that's one of their strong priorities And that's pretty much the update for d.o All right, great That's a lot of work That's how it goes before a druppal con Uh, well, are there any questions coming in? Nothing in the chat so far, but if you do have questions anyone on the call, please feel free to use the chat window to drop them in And i or maybe rachel will we'll call them out if we see them so far. It looks like we're good. All right excellent Well, we certainly appreciate your time and interest and the work that we're doing here at the Drupal association and we just couldn't do it without your support so um And it's important that we stay aligned with what the community needs. So feel free to Send us an email and say, hey, have you thought about this or you know, we're really seeing this need out there I didn't see it on your roadmap So go ahead and tell us those things because we're really listening and trying to prioritize where we can make the biggest impact And in the meantime, you can stay informed of our plans. We have our Drupal association newsletter so you can sign up for that and follow us on twitter And of course you can reach out to your account managers dalona and mark at any time and we're pretty accessible too You can always call me All right. Well then with that I say thank you and I look forward to giving you another update next quarter Thank you everyone


overcoming your anxiety, you can do that by activating your salivary response.  The first time I heard it, I chuckled until I was given the research. So here's what happens in the brain and why, for example, chewing on gum or sipping on citrus water when you're anxious. Citrus. Citrus water. It calms your nerves. Interesting. So this is what's happening in the brain. We all have experienced our mouth drawing up when we get anxious. Because of the brain's evolution, the amygdala picks up that dried mouth as a signal and it has excellent pattern matching, so to say, from the past evolution. And it says there's something dangerous happening here. So I got to go into fight or flight mode because the mouth is dried up. It picks up that pattern as danger and it starts producing cortisol in the brain. So what you're doing, you're essentially physiologically tricking the brain by activating the salivary response to say, look, nothing is threatening me. The brain picks up that new pattern and says, slow down the amount of cortisol. It's going in the brain. So these are things that are coming from the heart of science and it's validated by multiple papers, multiple institutions, very different experiments. I'll give you more if you're interested in different dimensions. More examples, man. Let's do this. So improving focus. And this also is also an edible form, but not everything is you have to eat or consume, right? But in order to improve your focus, you can chew on peppermint gum. You can improve your focus by up to 67%. Really? Peppermint gum. Peppermint gum. So what does that happen? There is research in biochemistry and then there's research in neuroscience which got to the same conclusion completely differently. The biochemists in two series of research, they found that the act of chewing carries more blood to your brain, which in turn carries more oxygen to your brain. Other research shows that peppermint has the same impact. Peppermint causes more blood flowing to your brain. So when you chew on peppermint gum, it has a double effect. When more blood comes to the brain, more oxygen comes to the brain, and oxygen is responsible for your focus. So if you have lack of oxygen, your brain just has a hard time focusing. This is the biochemist side. The neuroscientists, they do their tests with fMRIs and scanning the brain and so on. What I'm hearing is a business opportunity here. Creating... To create gums. Focus gums. Everyone... Now focus gum.com. Right. Which is a little bit nicotine in there too. With our tagline... With our tropic effect. Chew on your focus. I like that. A billion dollar business right there. But the neuroscientists do fMRIs and by scanning the brain, they notice that the act of chewing is a small enough distraction for the brain for it to not look for another distraction. Completely different finding... Completely different strategy. Similar findings. But it's very easy. So I tell that to founders in Toronto. I've told this to guys running incubators and accelerators. And I kid you not, the next day or three days later, they would send me a long email saying, Not that I only tried and it worked for me. I bought packs of peppermint gum and put it on everybody's desk. Right. So we always try to find these kind of techniques from science that are very novel, that someone like you who is very well read, who cares a lot about mental peak performance, it's innate in you and you've never come across it on a Google search. Do you have any examples of... So the examples you gave me are examples of adding things in your system, in your routine. Sure. The next question is, do you have examples of things to subtract? Yes. So another module. So every cognitive function in psychology compass usually translates to a module of its own. What I like about psychology compass, you're taking the theoretical. Yes. So scientific theoretical from psychology, neuroscience. Biochemistry, behavioral economics. They're all together. Yes. They're all interlaced together. And then theory aside, it's good to theorize. Yes. And it's cool that you can replicate it within a study. Yes. But obviously for me, I'm a practical human being. Yes.  Exactly. And that's the goal here, right? Not only that, I would add a second layer, which we care about and I think you care about. Not only what can I do now, which is the practical side, how can I measure the impact on me? Yeah, quantitative. Quantitative, which is the third pillar we're built on. Research-driven, practical, and with an ROI feedback loop. Because the joke I say, imagine you were on a diet and you didn't have a scale. So you had to go in front of the mirror and see if the diet is working. Right? If you can, if your measurement is subjective, it doesn't work. The same thing goes with the mind. We don't necessarily have a scale that everybody is accustomed to. So we built that scale as well. But to your earlier question, is there things that you can subtract? Yes. So we have all of these cognitive functions in the brain, ability to focus, communication skills, overcoming anxiety, et cetera. One of these cognitive functions is decision-making, which you do a lot of it. And believe it or not, in research, and this is something that resonates with me as well, because we all have some default decision-making frameworks that we fall onto. We're reactive as opposed to responsive. Instant. Robotic. Robotic. And it's because some of us, you know, sometimes we fall into a default decision-making framework that is correct for that problem. Correct. But a lot of times we just fall on our default, not knowing the type of problem. Right? So I'll give you a decision-making framework for a certain kind of problem, which is, I'm sure you've been in this situation many times, which is, let's say, you have multiple options to choose from, but you must only choose one. You cannot choose two. And it's a little bit of an unknown territory. So an example, a good example, let's say you want to do a marketing campaign to acquire a bunch of users. You can do it on Facebook. You can do it on Google. You can do SEO. You can do it on Reddit. But you can only choose one. And there's so many other variables in your mind that are competing with each other, which one has the biggest reach, which one has the most targeting, which one has the lowest cost, right? So how do you make that decision? So research is fun. I'm usually a victim in this situation, because my default decision-making framework is analytical. It's the computer science brain saying, get all the parameters, create this massive spreadsheet, build a formula, and then you'll figure out the thing. The opposite, just close your eyes and throw it against the wall. Everybody has their default. Research finds in this situation, because you can only choose one, pick the most important variable for the campaign that is important. So you might say, the most important thing is cost. I don't care about scalability. I don't care about focus on the demographics of the users. I just return on ad spend.  I'll go, I'll choose the option that meets that single variable the best. And research shows that that ends up being the best decision you can make. So these are in terms of removing, so you remove a layer of complexity in your decision-making and scientifically you end up at a more efficient result.


Hey guys welcome back to Come Again TV where all geek culture collides. Today we're gonna be taking another look at the 2016 Mattel classics Ghostbusters toy line with Ray Stanz. Ray Stanz of course was portrayed by Dan Ackroyd who co-wrote the script for Ghostbusters and actually originally created it alongside John Belushi. However he passed away and so they based Slimer the hotel ghost on John Belushi. Alright so let's take a look at Ray here. First things first I want to check something out real quick because his feet look a little bit bigger than Egon's did. So let me grab Egon here real quick and we'll compare the two. Last time we did take a look at Egon you know what I'm gonna turn the light on on this. They're with me for a minute guys. They are about the same size. I don't know it just it looked to me like they were a different sculpt because of course Ray is a bigger guy than Egon. Maybe not taller but bigger. So he would it would make sense that he would need a bigger foot. But we'll go ahead and put Egon back real quick. Alright so now on to Ray. At a distance I think he's a very good likeness of Dan Ackroyd. However up close see up close it's not really that great of a likeness. He just doesn't really look that much like Dan Ackroyd which you'd think it'd be easy to make it a lot easier to make him look like Dan Ackroyd. Then say it would be to make the Egon character look like Harold Ramis. But for some reason they just weren't able to get it that great. So anyway let's go ahead and take the Neutrino wand out of his hands. As I've said in previous reviews guys I don't play I don't mess around with these guys much at all. As soon as I get them take them out of the box. I look at them briefly and then they go up on my shelf. The Neutrino wand does peg into the side of the pack just like so. Take it off it pegs right there. See there's a little slot on the back of the Neutrino wand. It just pegs in there. I do wish they would have maybe put that red wire on another side of the Neutrino wand because it doesn't really sit that great on the pack itself because of that wire. So let's go ahead and take this off in order to take this off as with the previous reviews I have to kind of straighten his arms out as much as possible. Slide them backwards. This is always kind of a difficult part to do because it does like to get hung up. There we go. All right now as I stated with the Egon figure it does appear that the packs themselves came from a previous toy line. Copyright 2011. So it does appear that Mattel just reused some older proton packs. Still not bad. Very good likeness of the proton pack. It's got the four red lights here as well as the bar. Those four red lights in the video games they are pistons whenever the pack overheats using it too much.  Let it recharge cool down and then they go back in. But overall a really good likeness. I really like it. So let's move on to Ray here. All right so as with the other Ghostbusters in the line Ray's head is on a ball joint and he actually moves his head moves around a lot more than Egon's and Peter's. It actually kind of feels like it's just sitting freely in there really do not chance it. But yeah it looks like it's just kind of sitting freely in there. But it's nice that he has more articulation in his head than Peter and Egon do though. Very nice. The collar doesn't really enter it that much. His arms like I said they go up on my shelf I don't really mess with them a whole lot. They're just collectibles to me. So his arm can go up to there rotate all the way around and his arm his elbow straighten out that much. That's it. Which I don't really care for. It does seem to straighten out a lot more than Peter and Egon though. I don't know if that's because of the edge maybe it's a little bit looser. Still I wish I wish they would have put the joint inside the elbow pad rather than underneath it. You do have wrist articulation. This one seems to be gummed up. You gotta loosen it up a bit. Unbreak it. Turn all the way around. That's the same for both hands. You got waist articulation here. You got his leg can go up. As with all the others this little part of his belt does get in the way because it hits the hose and as I said before I think that hose is like a breather for the jumpsuits. It's never really clarified what the hose is for but I would imagine it is a breather. Allow the body to get some air because they do wear long johns underneath their jumpsuits you know as we see in Ghostbusters 2 it can get pretty hot so they need air flow coming in through there. His legs out to there and go back that far not far at all. He's got thigh swivel. You got knee swivel or knee rocker knee joint whatever you want to call it. You got boot articulation at the calf and then you've got the ankle rocker which the ankle rockers do work a lot more than say Peter's because they have their pants tucked into their boots whereas Peter has his hanging frilly. Overall not bad as I said my only gripes with these figures is I wish they would have put the joints on the outside of the elbow pads and with this one they could have did a better job of sculpting right now let's go ahead and put his pack back on him so I can show you guys how to do that. Let's bring his arms all the way back and they do like to get hung up so be very very careful. This neutrino wand first I was trying to get see the finger grooves that I was trying to get them lined up so that it'd be on the right side this wire the cable here for it wasn't really what to allow me to do that so there you have it guys the 2016 Mattel classics ghostbusters line Ray Stans. I'll see you next time guys when I take a look at the 2016 Mattel classics ghostbusters line Winston Zetemore. I'm Shannon for Come Again TV
