Well, school was out for Bemidji Area Schools today, but a few parents didn't have to worry about finding something for their kids to do thanks to a Bemidji-based after-school program. Reporter Cheryl Moore tells us about kids and company for this week's Golden Apple. School is out for conferences today for the Bemidji Area School District. So where do parents send their kids during the day? For many of them, it's all about the kids and company after-school program. The kind of way it works is just a quality after-school program for kids to come after and have homework help, hang out with their friends, safe quality spot for kids to enjoy their afternoon while their parents are still working. Kids and company is housed at all eight of the Bemidji Area Elementary Schools during the school week. On the days the district have off, all activities move to the Bemidji Middle School. The program hosts a variety of activities throughout the day, so kids have a lot of options. So they come in and they get checked in and then there are little free-choice based activities, such as arts and crafts, gym time, reading, and then they go into groups where they do group games and then they get the option to go swimming and then it's lunch and then after lunch it's usually a field trip or a movie on site and then free choice based activities in the afternoon till pick up. Today kids and company hosted around 75 kids. Throughout the rest of the school year, their numbers can vary depending on which school they're at and what time of year it is. During the summer months, however, that's when their numbers grow exponentially. They can get up to 200 kids at a time. Summer is going to be a lot more fun this year. I think we're going to try to do a little bit more field trips and get more kids' voice and child involvement into the program so that they kind of want to do what they want to do, come to our program. So yeah, that's kind of exciting things that are coming up. Kids and company also works with the schools and the building staff to determine their needs for each program day. Today, kids and company ran from 7.45 in the morning until 5.45 in night. Parents love it for the convenience. I think they just like the fact that we're involved in all aspects of the community. We're readily available so it's very easy for parents and kids to transition into our program from after school and even in the summer we're housed in sites that they're familiar with, they feel safe in.

Hello everybody, E here. Welcome back to another book slash movie haul because I'm gonna throw a movie in here Also at the end of the video I'm gonna talk about what I'm reading when I'm planning to read That kind of thing not what I've read because you guys know what I've read because I will have reviewed it on the channel Today I do have the one movie. I am ramping up for Happy happy hella days. You guys know how I love stupid puns Or word play and I'm gonna be doing 25 days of Christmas slash winter horror From the 1st of December to the 25th, and then I will likely take finally take a break From the daily videos until the 1st of the year and then we will start again I'm not sure if it'll be daily videos or not But I finally focused on a routine that I enjoy That keeps me from burning out and that's One day on three days off. I spend one day I shoot four videos in that day and then the next three days I read and write and hang out with the family and that kind of thing It's really worked so far as you guys have seen we are on seven weeks of daily videos And it's the longest streak I've ever had that is the only reason I'm kind of iffy about whether or not I actually want to take that week before the new year Off but if you guys are enjoying the daily videos Please let me know down there in the doobly-doo because one of the things that has happened with these daily videos is I'm getting less interaction I'm getting more money More subs and all that but I'm getting less interaction from you guys and the whole reason I do this channel is to interact with you But let's jump in to the book haul So or the the haul I should say because I have a movie This is one of my favorite Christmas horror movies And I wanted to I wanted to finally get a physical copy because I don't think it's available on streaming like Netflix You know, I don't want to call it free streaming, but Netflix Hulu that kind of thing It is it is available to rent on like Amazon Prime and everywhere else. But yeah Krampus. I absolutely love this movie I thought it was a blast from beginning to end and the creature designs are amazing I really loved the directors film trick-or-treat. That's another one I still haven't added to the collection, but I will but I thought this was a lot of fun I watched it shortly after I read Brahms book Krampus Which I will be reviewing. I'm not sure if I reviewed it already But if I have not then I will be reviewing on the chat channel for happy hella days But this one the character designs and everything are fantastic I'm trying to think of something that I haven't already said But it's it's one of those movies that gives me a good sense of Nostalgia for the holidays and also it has some pretty terrifying stuff in it. I feel I know The the reviews were mixed especially because of the ending. I like the ending I like the theatrical ending and I like the deleted scenes endings Next up I have two books that I received for review and then one that I bought myself The first one that I bought myself is creep by Lou Yardley I contacted Lou on Twitter and asked her Yeah, I've seen you and come to find out lose lose a fan of the channel I was like, yeah, I'd really like to check out your work And this is before I knew that she was a fan of the channel But I'd really like to check out your work because you're always interacting with me on Twitter And she said well here's a couple things that I have a novella coat Creep and I was like that one sounds like the winner So I'm gonna be reading this this month before December So keep an eye out for that one next up our books that I got for review These are review copies of course, but I got the stop very very basic cover That's a hoodie if you can't see the stop by W. Dale Jordan I believe we follow each other on Twitter She asked if there was anybody who wanted to I I ask for review requests I'm permanently closed to review requests. So don't message me I go out looking for books that I think I will enjoy and Jordan Said that they were looking for reviewers and it's a novella very very short Let's see here, but it's let's see 93 93 pages I'll go ahead and read the description on this one. What would you do to protect? What's yours Donnie's whole world changed the day he met Nate at the stop? Sorry, it's the stop that I say the shop I can't remember a cruising spot outside of small Texas town Nate saw him knew him cared for him And then one day in an incomprehensible act of violence Nate was taken from him Broken but not beaten Donnie steps into Nate's role at the stop with one goal in mind Find a man who murdered his lover and see just a served no matter the cost I like stories like that. I think I knew about the the gist of the story and that's why I wanted to grab it Anyways, that's why I'm reading the the synopsis for this one But next up we have yet another book Turner publishing has been absolutely fantastic to me and we will talk about one of the books I've already unhauled it, but we'll talk about that one because I'm starting it next They have been absolutely fantastic to me lately They're sending me all of their new stuff and I'm hyped for all of it spontaneous human combustion from Richard Thomas is my favorite collection of the year And I'm hyped for well, we'll get to that later, but they sent me this one because I requested it I saw it on their Instagram and the cover just knocked my socks off This is the temps and I'm going to tell you I'm going to read the description because that's another reason Why I requested it so Jacob Elliott doesn't want a temporary job in the mail room of Delphi Enterprises but after two post college years of unpaid internships and living in his parents basement. He needs work Then on his first day the unthinkable happens happens Toxic gas descends on him on a meeting in Delphi's outdoor amphitheater He'll killing all the regular employees and leaving Jacob stranded inside the vast office complex Wandering through Delphi headquarters Jacob finds other survivors Lauren the disillusioned Classics major who's now writing online personality quizzes Swatty the fitness instructor trying to escape a toxic relationship and Dominic the business school student who will do almost anything to get ahead Stranded in the wreckage of the company that employed them the temps have band together to create a miniature world That's part spring break part office culture that said that sold me Until a shocking discovery disrupts the survivors self-made paradise and drives them to uncover the truth about the mysterious Corporation that employed them and the apocalypse that brought their world to an end But I mean that cover look at how how it pops as a gorgeous man the the colorful People in gas masks that the font everything about this this cover draws me in so so kudos to whoever did the design Let me actually look that up because yeah, um jacket design by Lauren Peters Caulier C-O-L-L-A-E-R. So the fantastic work on that and now we're gonna talk about what I what I'm reading And what I plan to read Matthew Lyons, which I read the night Well, I can never remember the name of his book But his new one's called a black and endless sky Turner publishing sent me that one for a review and I'm gonna be starting it tonight I'm shooting this video on Friday the video should go up on Sunday. I'm trying to do a Sunday wrap-ups and book hauls every single week But I'm excited for that one because I loved his last one It was one of my favorite books of last year So I'm excited to start that one. I am still working on Haley Piper's Unfortunate elements of my anatomy that review should be up sometime before December Another thing is I need your guys's help on what to read for for next month I only have a few spots open for for shorter books. I've read the terror. I've read Planting to reach Bracken McLeod stranded, but I've read Krampus by Braum. I've read. Let's see here Bone White by Ronald Malfee I'm sure you guys will mention books that I've already read But if you want to go ahead and leave comments down there in the doobly-doo about what you would like me to read especially if it's short Christmas horror or Novella length Christmas horror and it doesn't really even have to be Christmas It can be winter themed as long as the entire book is based in a cold Environment and don't say the shining. I've read the shining a billion times But yeah, so if you guys will help me out with that. I appreciate you I'm also listening to the third happen Leonard book by Joe Lansdale That one is the two bear Mambo and I should have that review up sometime this week But that's everything. That's a weekly wrap-up. That's a book haul one movie all that good stuff If you guys want to list down there your own book hauls, please don't link me to your own videos because I have Because of spam I have links Hyperlinks blocked on the channel, but if you want to hit me up on Twitter links down there in the doobly-doo if you want to Hit me up there Head on over to Twitter and link me to your lists there or on Instagram But I don't think Instagram lets you post links either if they do they don't show up as links It's just a you know just just a text, but anyways Yeah, if you want to type out what what you got What you're looking forward to what you're reading all that good stuff down there in the doobly-doo, but until next time I have any you've been you this has been another book haul and everything else. I'll talk to you guys later. Bye. Bye


Over the years I have amassed a collection of running medals, which my wife refuses to allow me to hang in the house. She says it's the height of running wankery. So as an unabashed running wanker I have hung my medals here in the shed. So for the next few weeks I thought it might be quite fun to do a short medal Monday video each week telling the story of some of these bits of metal with ribbon attached to them hanging from a curtain rail in my shed. And what better way to start than with the London Marathon arguably the biggest and most well-known of the races I've taken part in. I've done five London Marathons and one virtual London. It was after many years of trying that I finally got into the London Marathon through the ballot in 2015. This is my medal from that year. I remember it was freezing cold and I had to wear two bin liners which I got from the Costa Coffee in Blackheath on the way up to the blue start. I had quite a good run but I slowed down significantly after 20 miles and eventually finished in three hours and 18 minutes. The following year I managed to enter by good for age qualification this is my 2016 London Marathon medal and it remains to this date my fastest London Marathon so far and my second fastest ever marathon at three hours and nine minutes. In 2017 I ran the London Marathon with a media entry. Myself and Martin Yelling had been contracted to film a series of training videos which would show the London Marathon from the inside. I did the camerawork and Martin was the talent. It was a super hot day I remember and because we were running backwards and forwards along the course filming various things it took us five hours and we ran well over 43 kilometers. By the way if you're enjoying the video finding it useful or interesting please do hit the like button and if you're not subscribed already please do subscribe that would be awesome and don't forget to hit the notifications bell as well. Thank you very much. Now if 2017 was hot well 2018 was an absolute scorcher. I managed to qualify as good for age for this year. Here's my 2018 medal. For spectators it was merely a warm day but for runners it was absolute torture and unfortunately I chosen this year to try for a PB. I got to halfway in one hour 33 minutes but like many others I succumbed to the weather and I couldn't hold on. I eventually finished in three hours and 24 minutes. I didn't qualify for London all make it in through the ballot for the next three years although I did do the virtual London event in 2020. It was an incredibly windy day. I had planned to run laps up and down wording seafront but the wind was so strong in one direction that at halfway I decided to just run with the wind behind me all the way to Brighton. Officially the London marathon phone app has me finishing in three hours 21 minutes but I prefer to rely on my Garmin watch which told me I finished in three hours 24. Having finally run another good for age qualifying time I was able to run the London marathon again in 2022 and here's the medal for that race. I was hoping for a GFA time again which for me would have been under three hours 15 minutes but despite a good first 20 miles I faded in the last 10k and finished in three hours 23 minutes. However it was a great race and the crowds this year for some reason seemed bigger and louder than I've ever experienced before. Hopefully with a little bit of luck and some more training I'll get to run the London marathon again over the next few years but have you run the London marathon? Let me know in the comments down below. What did you think of it? Would you recommend it to a friend? Would you do it again? Is it a good course for a marathon PB? Let me know all that in the comments down below and also if you've run it more than once what is your best time on the London marathon? Thank you very much for watching everyone. If you'd like to see my London marathon from 2022 then that is linked just here so click on that for the next video and we'll see you on the start line next time.


Gary Linnaker Gary Linnaker? What first? There's two clubs, so one of them moved to one and the other moved to the other. Sound owned? From? Which ones have you moved from? Which two Premier League clubs have they gone to? One's gone to one? One's gone to Swansea. That's correct. And the other one is... I've lost it, don't I? It'll be an American. I'm ashamed of him. Can I honestly tell you? I don't know. This is cricket. Nottinghamshire? 18. The 18th. 19. Yeah. 64. 1963. Helsinki? That is... I can't remember. Either way, lost this year. It'll be lower than that. What is it? I'm going to go with Gloffs this year. Wiltre? I watch this every night as well. I don't think of his name. I can't remember his name. It's... I don't know how to pronounce his surname, really. I won't pull your pronunciation. I actually know who it is as well. I can't even think.  Can you do the G or something with his surname? I watched a film with him the other day as well. Can I think of his name? Drake Jilnholl. So it could be a bi-bandara girl. There's so many it could have been. It's Eva. Take that, Westlife or Spice Girls for me. Spice Girls. It's Eva, a girl, a bandara, a bi-bandara. Take that. Sheffield? I will say... I think I'll be wrong, but I'll say Sheffield. Two. Two? That's a cross, isn't it? That is a radius. It's like a mechanism or something like that. I don't know. I will say Sweden. All right, so both of you guys. You got 6.8 from the face-to-face quiz yesterday. To decide the winner, I've got a bonus question. According to figures produced by the Office for National Statistics in June 2015, what is the estimated population of Bradford? And the nearest goes through. OK, so you can see your answers. It's Lidl who gets it. 528,200. Half a million. Well played.


Okay, we're back here live in New York City for Hadoop World of Strata plus Hadoop World. This is where the big action is. Big data week in New York City, a lot of action. It's our day two of Silicon Angles, exclusive coverage of O'Reilly and Cloudera's Strata plus Hadoop World. We're excited to be here. And my two guests joining me is Steve Wacheef, Hadoop Technologist at Eula Packard, HP, and Amra Awadala, the co-founder and now CTO, not the VP of Engineering, CTO of Cloudera, CUBE alumni, good friend. And it was on the CUBE that Amra said that about Hadoop three years ago now, three and a half years ago, I saw the future and started Cloudera. So great to have you back on again, Amra. Thanks for having me. You're a rock star in the community and obviously great technical leader at Cloudera, co-founding is doing great. So welcome to the CUBE. Thanks, glad to be here. So Steve, obviously we love HP, we follow HP closely. Obviously there's a lot of stuff orbiting around HP as a company, but within the group that you're in, Enterprise Services or ESSN, which is what's called, they're in the convergent networking space, infrastructure, networking storage servers and have led that game for many, many years. Right. And now with Flash, Solid State, converging infrastructure is morphing to a whole other IO-centric infrastructure where Hadoop becomes important when you have industry standard hardware like what HP offers. So tell us one before you get into the whole big data Hadoop, Cloudera relationship, what are you guys doing with Hadoop right now? What's the internal view and roadmap of big data within HP? So absolutely, you know I think when we look at Hadoop we sort of have two perspectives and two areas that we want to address which is that one there's a lot of platform complexity. So customers struggle to understand what hardware do I buy and how do I configure that hardware and manage that hardware for Hadoop. And then the other aspect is application complexity which is how do I apply Hadoop once I have it to solve my business problems, right? So we're focusing on both those areas. My group, HP as a whole, my group specifically focuses on the platform complexity. We have reference architectures for Hadoop as well as an appliance for Hadoop. So obviously within HP they had that billions of dollars they spent on autonomy which is essentially the software side now. But there's really two problems happening in this ecosystem. One is obviously the software and the big data analytics, the application side. But also there's a lot of technical challenges on compute. A lot of energy and making it all work. Is that where you're now focused or are you also transitioning? Do you trade over to the autonomy groups? So we tend to go in with Hadoop, autonomy and Vertica when we go and talk, you know, have a customer conversation about data management. They sort of all do different things. You know, you sort of look at if it's a scale you have autonomy on the far left with unstructured document level analysis indexing. Vertica on the far right which is structured data, real time access and then you have Hadoop which is sort of on the slider in the middle that can sort of move around. And so we tend to just take a consultative approach and figure out what works best for the customer. So Amar I want to ask you a couple of questions because since we last talked you transitioned as VP of engineering at Cloudera, obviously the co-founder to CTO. And as the market moves more to the business value conversation which has been a big part of our topics this week. You're now talking to partners now. So is your new role, you're stepping out of the day-to-day engineering which you now have a VP of engineering. Explain the transition of your role and what you're working on now. It's standard, that happens with many, many enterprises and you need both functions as companies grows. You need them to be separate. The VP engineering is about the tackling and the hiring. Right, it's about hiring the engineers about executing on the protocol maps. Shipping code. Shipping the releases all the time. So it's a very tactical role. Which you did very well for many years. I started the company at the beginning and built the team to about 100 engineers and that's when I handed it off. The CTO role is a more strategic role about where the company should be going with this technology, how to stay aligned with what our customers and our partners are asking for and what they're building and how to make sure it all fits in the long term. So that's kind of what the CTO role entails. That said, it's sometimes very hard to define what a CTO actually does. So when I was in the process of kind of crafting the new CTO role for myself, I talked to a number of famous CTOs in the valley. One of them is Greg Papadopoulos, who was the ex-CTO for son. And he said a very interesting, he gave me a very interesting quote actually. He said, a CTO is like the CFO in this sense. The CFO is not responsible for making the revenues. The sales team makes the revenues. However, if the CFO mispredicts the revenues, you fire the CFO. So in the same sense, the CTO is not responsible for building the product. The engineering team builds the product. However, if the CTO mispredicts a key trend that affects where the product should be going, you fire the CTO. Yeah, so let's talk about those trends, because by the way, that's a brilliant suggestion because you have to scour the landscape. So I know you've been doing a lot of travel and I tried to, I was in the office, I should see if you're around. Yeah, we say sometimes the CTO is chief travel officer. Chief travel officer. You got me on that. I was trying to sneak that one in there. Okay, so you're actually in China and with Mike and Kurt, so you guys are, it's a global landscape now, so the market's changing. So what are you observing on the market side? Obviously, Hadoop is now mainstream to the point where Big Day is no longer just Hadoop, it's other things. Actually, I wouldn't say it's mainstream here. We're not mainstream, we're still at the beginning. We're still at the beginning of this movement. It's going to be a massive movement. It's going to take years to reach this maturity. So I wouldn't say we are mainstream. I mean, it's definitely growing very quickly. This event now is, what, 2500 people showing up at this event? Yeah. Four years ago it was just 500, so you can see at the graph. Okay, so I'd be gonna say more diverse with the more actors and business involved. So, I would agree with you. But I define mainstream to be more about where VMworld is. Like VMworld now is like 30,000 people go to VMworld. Oracle world is what, like 90,000 people. Virtualization. Yeah. So we're still like a few years away from that. Just don't sell for 600 million dollars to EMC.  Then a $40 billion dollar market cap. Oh, that's it for the first thing. I know you know the VMware guys. I love them. Shout out to EMC and VMware. I love Pat Gelsinger who's been on theCUBE many times. Genius move. So, always good entertainment on theCUBE. Always fun. Okay, so that's good. So the trend-wise, you know, as you look at the landscape, HP has a lot of moving parts. So how do you look at partnering with HP, for example? Because like I said, they have a lot of moving parts. Huge conglomerate company. They got autonomy, they got Vertica, and they got ESSN. All huge opportunities. And ESC ends the muscle. Yeah, I mean, at first it's not a question that HP is the quintessential Silicon Valley company. So, I mean, we are born in Silicon Valley. We are part of the newer kind of generation of companies in there. It would be a shame on us if we don't partner with somebody like HP. Now they have many, many products that we need to integrate with. And right now the most obvious ones is as Steve highlighted earlier, was to get up and running a Hadoop cluster with all the hardware on the server side, on the network side, it is a complex proposition. It's not something that you can do. We were just at IBM IOD and they're now positioning big data. And they are not forking Hadoop. They are embracing Hadoop into their entire offerings. But they may have some top-level solutions that are more built for... Same thing, same thing. Like on the IBM side, you have NITISA. On the HP side, you have Vertica. On the IBM, what's the equivalent of IBM for search for autonomy? I don't know. I don't. Infosphere?  You know, I think you've got to get the, you know, the horse in front of the cart, right? So when customers talk to us about Hadoop, right? You've got to be careful about coming in straight away to the line of business, I think. Because they can go off and sort of start to figure out how to decompose things that are business problems into things that run as MapReduce. But there's a huge learning curve that's happening in the data center where these guys just don't grow Hadoop, right? And so, you know, we're really trying to make this simple and basically get them the platform first. So that's the horse in front of the cart. And then you come in and layer those solutions on top of that. Let the use cases drive more of an a la cart. Yes, yes. I mean, so we say, like we frequently would say there's so much buzz around big data, which is nice in everything because it starts the conversation. But at the end of the day, you need to be solving a real business problem. Absolutely, yeah. So we just look, we love of course all of the buzz and so on and so on. But I say like this big data movement is very similar to the e-business movement that happened a decade ago, right? It's just business. Just business. We're doing it with the technology. No one talks about e-business anymore. Yeah, exactly. Are you an e-business? No, no, everyone's e-business. It's 100% penetration. We think the same thing would happen with data. Like, you know, they did it right now a few years ago. In fact, we made that call just two days ago. We said, big data will be no longer, just like e-business. Are you in big data business?  So I think solutions are driving it, right? So like, no one talks about client server anymore. Yeah, exactly.  Yeah. It really is, I mean, it's sort of, to quote an adage, you know, everything's bigger in Texas. It's just where I live, you know? We don't have big data. We just have data. Right? All right, so, Amar, I want to talk about partnerships. So you guys have been very successful. I talked to Mike Olson on the yesterday and looking at your briefings. Obviously, Impala, huge deal, great, great success. But as you roll out Impala, the big data platform, you have new logos and everything, you guys have been successful with your partnership, Milestones, looking at the business performance. The partnerships have been impressive and they're growing significantly. What are you seeing when you talk to, like, say, HP and other partners around, what's working, what's their mindset? Where's their, what's the psychology right now in the marketplace? I'll see platforms, you touched on a little bit of it. Can you expand more on that relationship? As the things cross the chasm, people who are running business, like HP and other companies, they have to integrate in, what's the mindset, what's some of the conversations that you're having? I mean, the theme is the same one we just discussed earlier, which is the buzz is great and everything, but we are about providing solutions. And when you're providing a solution, there isn't just one fixed formula that solves everything. It's a mix of things that will lead to solving the business case that the business is trying to achieve. And that's why these partnerships are very important. And that's why it's important to distinguish in the market between partnerships, which is what we call Barney partnerships, which means talk, hey, shake my hand. Yeah, we love you. Yeah, we love you, you're right. Barney, yeah, Barney, Barney deal. This is two solid partnerships where we're together delivering a solution Well, let's talk about the Barney partnership versus the real delivery because Barney, I love you, I love you, I've got that. But one of the dangers you mentioned was you get salespeople selling something too early and you can have some missed delivery there. So where are we on the delivery side? HP's a great example because when they sell, Donna Telly, I know him, I talk to him, I know him personally, he's a sales machine. He's not gonna, well, if we had this, no, it's gotta be baked. So what is it? So I've got a comment there, right? So our strategic relationship with Cloudera grew out of our natural business partnering where we started meeting in the market. It started with our sales force going, hey, customers are asking for Cloudera solutions on our hardware, let's strategically align this so we can deliver more efficiently. So I just think it's a natural organic evolution. That's a good response, I think that's legit because that's really what was happening. You guys make the industry standard hardware. If I said commodity hardware, we'd be getting phone calls from the server guys that Contier would be like, what are you doing? So like, no, industry's. You should give her a chance to counter them. Yeah, yeah, well, no, so I think it's a great point, right? So what is commodity? You know, it's a personal frustration of mine.  And there's a perception that commodity means cheap. Commodity to me means that you're getting those same resources more, the price performance is much better by scaling out and scaling up. That's what commodity means. It doesn't mean cheap. Yeah, I know.  Yeah, yeah. We build our own servers and we call that ghetto servers. Because it's cheap, and you know what, there's a lot of risk points but we're starting up. That's the fun about Hadoop.   But that's what's fun about Hadoop, right? I mean, I've had Hadoop clusters with laptops in my cluster. You know, if I'm trying to solve a particular, do some data set analysis, it's you use what you got, right? It's easier to manage if it's a margin of course. I was showing on our H-Base app last night and I'm embarrassed by how cheap or low cost the hardware is. And I think that's the general consensus of Hadoop. People say, hey, you know what? I can implement solutions in a very low cost way and that actually is tailor made for an HP because now you can then bring in other elements but the risk is, if it goes down, if you don't have the right support, it crashes. But you know, Hadoop is great. But thank you for your question, which is very important to want about the partnerships and a big company like HP, a big company like IBM or Oracle and many of our other partners, they don't move into a new market unless the customers are giving them the strong signal that we're ready for this, right? So this is not jumping ahead of putting the horse in front of the horse, it's not. Yeah, and also the other thing I would point out, just my observation in doing our CUBE interviews and talking to a lot of those players the business is so massive at the scale of an HP is that Hadoop is not cannibalizing it, it's just shifting the solutions and there's a lot of mash-ups so above Hadoop there's other things, you got graph database time series like IBM has an informix. There's all kinds of different stuff. There's not a mutually exclusive environment, right? So Hadoop works well and then we'll grow. So that's a big misconception that I hear from people is they, oh, Hadoop has to take away from something else. Actually, we're seeing a structured RDM relational databases actually expand. Those scope of projects are actually expanding. So, okay, great guys, thanks for coming inside the CUBE. Final question, we always do this. One year out to five years out, shoot the arrow forward. We're in the Hadoop big data, data-cosm ecosystem, whatever you want to call it. It's early, it's crossing the chasm on its way, I think, to a mainstream revolution. As I posted on SiliconANGLE today, I called it the South by Southwest for Geeks, Hadoop World. So, shoot forward. What's happening in the market relative to overall growth? How's it going to evolve? Just your vision. So I want to talk about one thing, which is it's not necessarily even that visionary, but it'll be one year from now, which is HP Moonshot Platform, right? Works great for Hadoop. Hadoop's a natural platform where you can partition the computation. And we've got our system-on-a-chip Moonshot Platform that's coming out. We plan to provide reference to architectures on it next year. And I think that's going to be quite revolutionary. We have Armour and Cloudera revolutionizing the data management middleware stack, and we're going to come in and revolutionize the data center. I just want to interrupt you there because I want to share with the audience out there. Moonshot is, I mean, HP's new hardware platform based on low energy consumption. We had a whole CUBE segment at HP Labs. So if you search HP Moonshot SiliconANGLE on YouTube, you'll find a slew of great videos on there. This is absolutely revolutionary hardware.  So I'm sure people haven't heard about it yet, but you will check out Moonshot. So that was a good vision there, Armour. So a year out, I would say Impala will turn this industry upside down in more than one way and expect to see more things from us along these lines, along the Impala lines, and that meaning low latency. So low latency is definitely a very big theme for 2013. And then five years out, Hadoop World will be as big as VMworld. It's going to be 20,000 people for this event. Okay. That's when we can say it's mainstream. Okay, mainstream Hadoop in five years, I think maybe sooner, who knows, with this kind of pace. Exciting, Steve Wacheef, Hadoop Technologies at HP and Armour are all co-founder and CTO of Cloudera inside the CUBE. We'll be right back with our next guest right after the short break. Thank you. Thank you. All right, that was good. It was fun. Oh, that Moonshot, I've had more time. We looked at all the programs out there and identified a gap in tech news coverage. There are plenty of tech shows.


Is it possible to be authentic and still use the practical business goal setting, target setting thing? So I want to thank Eliza for asking this question and hear my thoughts on this. Yes, it is. I set goals also and yet I stay curious and playful about my goals. I think that's a really big thing because I used to be one of those people that, oh set goals, I got to get 100 sales of this product or whatever and I'm going to do whatever I need to to make that happen. And whenever we start getting into this by any means necessary energy, it creates, I think it creates violence. It creates violence within us, maybe even externally. And so I say let's set goals fine, but let's be curious and playful about those goals. Hey, I wonder if I could get there. Well, let's play. Let's play with it. Let's experiment with what we might do to see if we get close to it or surpass it. Who knows? So that kind of playful, curious energy is what I do. Secondly is I set goals based on the trajectory of whatever that activity has been. So if I have been selling 50 spots in my monthly courses, let's say, then maybe for the past three months, I've been selling 50 per month on average. Then maybe next month I'll say, hey, I'm going to see if I can sell 55 or 60. So it's grounded in reality. It's along the trajectory and I know that if I keep doing what I do and maybe make some improvements, I will make slightly more sales. If trajectory continues, but a lot of people, what they do is they make completely ungrounded fantastical goals because they heard from some law of attraction stuff that, oh, you set really high goals and maybe you'll get there.  And I've seen more people fail thanks to law of attraction than I have seen people succeed. That's just reality of it. I think the problem is that the law of attraction needs to be applied to what I call process goals rather than results goals. Results goals, you stay playful and curious about it and experimental. But the process goal, what is a process goal? A process goal is what am I actually going to do? What is the plan? What is the process when I show up each day to move towards my results goals? But what is the process each day? Am I going to dedicate myself to the process? That is the goal. The goal is every day I focus on my process goals. I'm going to do this from 10 to 11. I'm going to work on this from two to three. I'm going to work on that and part of the process. This is where law of attraction comes in. It's to imagine myself doing those actions with joy and with love and with wisdom and with ease. Now that's, I love attraction all day long. I love attraction all day long, but not the way most people do it. I love attraction, my actions, not my results, my goals. As another example, earlier this year, I was selling my course, Joyful Productivity. Now, this is a passion project of mine. It's not something that most people love to buy from me. After the first day of sales, I'm like, oh my God, I'm not going to reach my goal of, let's say 50. So then I said, okay, fine, I'm going to set a goal of just 20 sales. I'll be happy if I get to 20 sales. I played with it, but I still kept showing up every day and joyfully did my marketing and did it with passion, love, etc. And guess what? I kept thinking the goal was going to be 20. I sold 70 instead. So yet another example why love attraction doesn't work when it comes to numbers, when it comes to results. By the way, love attraction works when it comes to relationships. I've seen that when it comes to health. I've seen that as well. But when it comes to business numbers, love attraction tends to create distraction, discouragement and disappointment and slowing down of your actions. So rather than love attraction, your numbers, love attraction, your actions, your process goals. So process goals are really about time and energy management. How are you managing your time and energy? That's what you should be more most concerned about and your values. And then, and then results is the results goals are more about playfulness and surrender.  Do you trust that? That is I think the number one thing that we all need to remind my remind ourselves is every day, we're going to be taken care of no matter what. I am not a trust fund kid. I don't have savings for my parents. I had to work everything for myself, support myself, my my own family, I have support my own family. Now I'm supporting my parents too. So I do everything myself. I don't trust but I still believe that I'm going to be taken care of because there's a there's a greater power, higher power, taken care of you and taken care of me that the purpose of life is not to achieve success financially. We may get there and we some of us are blessed with that. I think the purpose of life is to enjoy every day and approach it with as much love and wisdom as we can. That's why we're here. We're not here to achieve some external goals. We're here to achieve some internal goals. Right? So I hope this is helpful and interesting anyway. And yeah, until the next video, remember to separate your results goals and your process goals. Use law of attraction on your process goals and just play and just be playful and curious about your results goals. That's all. Okay. I hope this helps and I'll see you. I'll see you later. Be well.


My name is Don Cripal. I'm currently Director of Eye Detect Services with the Capital Center for Credibility Assessment, C3A. Also a member of the Converis Technical Advisory Board for Eye Detect. I have three years of federal service, all of it in the Credibility Assessment Arena, primarily in the area of polygraph but more recently in other technologies as well. One of the chief advantages of the Eye Detect system is that each individual can be tested in about 30 minutes and the results return in about five minutes, which that means is that the entire process, the adding of the Eye Detect system really doesn't encumber the larger process because it's so quick and so efficient. The Eye Detect technology actually comes at a good time because certain government agencies are experiencing congressional and presidential demands to hire a large number of agents for programs that require a polygraph. One of those organizations is Customs and Border Protection, or CBP. CBP has been mandated to hire thousands of agents to help secure our nation's borders. Getting those individuals through the CBP hiring process is very, very long and a large percentage of those applicants have been found during the polygraph examination to have been involved in serious criminal activity or have drug-related problems. It might be possible to use the Eye Detect technology at the front of the hiring process at CBP such as at the hiring events to screen out individuals who are less likely to be successful in the polygraph examination. And in fact, the company I work for, C3A, has an unsolicited proposal before CBP at this moment to offer the technology specifically for this application to help them meet their hiring goals. For those agencies who have not yet had an opportunity to see the Eye Detect system, it is certainly worth your time to arrange a demonstration. The Eye Detect technology would allow your organization to streamline its processes. It will actually end up saving resources for an organization, which is always a challenge. But in the end, it actually serves to protect information or protect national security in a way that previously was really not possible.


So hello everybody. Thank you. Thank you for for being here. My name is John Lillich So today, we'll talk a little bit. We'll sort of dive a little bit deeper into Cryptocurrencies crypto assets. We'll try to understand it in a much Let's say broader financial context If you're on Twitter, feel free to add me I've got some slides. I won't go through all of them, but we'll kind of like touch upon some of the main points So many of you have probably seen this but it's just a little bit of context on like how big money is how big sort of You know the financial context relative to where we are with Bitcoin, although this is quite a while ago But you can see there's a sort of an ever-growing cascading set of opportunities for crypto assets to Play you know play a role Okay, so this is an interesting slide because my interpretation of it is basically There's really no way to guess the price of Bitcoin or any of this stuff. It's sort of very often uncorrelated to You know traditional assets where they might have some Indicators in the economy that kind of determine price With Bitcoin and crypto You know this stuff is still very volatile and oftentimes it's extremely difficult to sort of predict what What the price could be? So many of you or some of you perhaps have heard of this notion of an ICO Or a token sale and these are basically sort of issuance of crypto assets That can sort of take on many different forms and so if you have an interesting software project and maybe there is a an application that you're building and Critical to that application is the utility or the function functionality of a token You can sort of sell that token on Ethereum You can collect Ether and in this way we have this sort of equity crowdfunding Model and it's sort of eating the world right now It's it's definitely changing the way we allocate capital particularly in the past where you would sort of have to go to a Silicon Valley venture capitalists and like beg for money So there's a few different kinds of tokens Maybe some of you are familiar with protocol tokens. So these are things like Ethereum or things like ad chain representing Protocols like token curated registries Utility tokens are tokens that sort of are necessary to the functionality of a particular piece of software There's a really interesting prediction market called gnosis and in order to sort of like Gain wisdom from the crowd and use the application. You need the token and then of course security tokens This is kind of the thing I want to highlight a little bit in this discussion So securities are financial instruments that are issued typically by very large financial institutions and These instruments sort of have an expectation of profit and You can you can sort of purchase these instruments And and so this is kind of the derivative the securities market if you will The security token market has yet to really take hold But my contention here would be that if you're thinking about crypto assets from an investor perspective or if you're an entrepreneur think deeply about how the traditional financial system works how traditional assets work and Potentially how those can be replicated on blockchain and the reason you'd want to do that is because Like if you think about Bitcoin, the reason Bitcoin is yours is because you have custody of the private key Likewise, if you think about complex financial instruments, why wouldn't you want to have custody over that? Like why would you want to leave it in the hands of Lehman brothers or Bear Stearns or something? And So when you're kind of designing utility tokens, there's a few different things to consider governance being one of the key issues surrounding this ecosystem right now as far as Exactly how the community interacts with various elements of your project Okay, so there's obviously been a lot of news about You know these massive token sales generating tremendous amounts of money my contention would be that And and there's a variety there's a spectrum of opinions on it some are sort of like well This is ridiculous and others are really embracing what's happening My contention would be again if you think deeply about these things the history of investing in tech has always been pretty ugly there's always been sort of venture capital allocated into tech where Effectively capital was misappropriated or investments failed the same thing happens quite often in this case However, because it's on the blockchain. It's all very public. It's all very public and because it's public you sort of can't run and hide and Because it's in public then you know the ecosystem evolves very very quickly So we're seeing tremendous evolution and I would say progress and on many fronts Okay, so these are some of the like ones in the past the theory and being kind of the first significant if you will ICO and There's been other since that have sort of done spectacularly well These are just a few of them. I think the IOTA guy was just on stage earlier Of course, there's a lot of different interest institutionally empty gox was a really famous kind of example here in Japan coin check Recently also became famous You know, these are just some of the exchanges Okay, so thinking about derivatives and And so diving deep, you know more, you know deeper into this conversation beyond just okay Well, what is a Bitcoin? I have a Bitcoin the price goes up. I can make some money. I can sort of like transact with it Thinking much deeper beyond that and saying well, what if there are financial opportunities that I can invest in? where I Potentially have a yield. Okay, so imagine a scenario where Let's take a developing country like the Philippines for example where real estate is growing very very quickly And you wanted to sort of get a Exposure to that well right now that would be very very difficult using traditional financial instruments There would be a series of friction points along the way that would make that sort of difficult But but if you could imagine in the near in the very near term Tokenizing so creating crypto assets that represent ownership in a building let's say or represent Ownership or a claim to the yield generated the income generated from a property So imagine a private invest private real estate investment fund owning a lot of assets a lot of properties those properties generate revenue The revenue from from those properties is converted into ether Ether is put in a smart contract and then you know that those sets of properties can issue their own tokens And if you have a token you can then withdraw your share of the ether or the yield So this is a this is this is sort of like an opportunity to go beyond just Holding and speculating tokens and getting into a position where you can generate yield Okay, so you get return on your investment in addition to holding the tokens And there's a bunch of projects and a lot of really cool stuff happening variable is a really interesting sort of peer-to-peer Decentralized platform where you can kind of like trade a lot of these Derivative crypto assets Decentralized exchanges are going to be an important element of the of the coming sort of You know crypto asset web 3 future We have seen obviously here in Japan most recently with coin check and around the world in other places where the you know Sort of centralized exchanges have been compromised. I have to give a lot of credit to the guys at coin check I actually know them. They like had the money and paid it back, which is amazing And it's a testament to how well their business was doing but as we sort of You know evolve as this ecosystem Proliferates around the world. It's very important that we have Decentralized exchanges where users retain custody of their asset at all times like you don't relinquish custody to an exchange And trust them to sort of not get hacked or breached So regulatory stuff and I'll go through these slides pretty quickly So there's there's a lot of sort of existing laws and and some of those are difficult to navigate and maybe Well, obviously weren't really constructed with crypto assets in mind But that is changing and we're seeing regulatory change here in Japan obviously the FSA and other You know regulators have issued licenses and guidelines and this is sort of happening around the world The SEC the United States is actively Sort of making comments and taking action and then of course you've got different jurisdictions around the world that are Really competing to attract business most recently Binance, which is a very large exchange out of China moved to Malta Because they had favorable sort of regulatory conditions and so as this And so if you're thinking about it from an investor perspective Understanding the regulatory kind of landscape and as it shifts is very important because that's going to be the the determining factor for when Securities on the blockchain become much more ubiquitous So these are just some of the places I was talking about. There's a bunch of stuff happening around the world We'll skip this stuff This is sort of Gibraltar Gibraltar is interesting. It's a it's an interesting framework They're really kind of innovating on the regulatory side and We'll kind of skip through some of this This is called the Brooklyn project and the reason I'm kind of spending some time on the regulatory side of it Is because again, I want to like emphasize how important Understanding what is happening on the regulatory side is going to be as far as investors being able to make smart determinations about You know, which which assets and which products they want to they want to sort of invest in You're going to see derivatives and securities on the blockchain issued by groups that either follow regulatory Guidelines or don't and the ones that don't are likely to be very very high risk That's why it's that's why it's important to kind of at least have a sense for all this stuff in Brooklyn We along with a bunch of others kicked off a process It's a sort of collaborative effort between many different groups many different regulators and we're hoping to sort of help construct guidelines for how to deal with these things okay, so Thinking about Exchanges again coin check was a big deal here in Japan and it's had tremendous impact already There's massive regulatory change coming the industry is changing very quickly here in Japan. So from a security perspective You know, you will see more regulation and you will see more institutional participation For example, I wouldn't be surprised if you see soft bank investment or some other major kind of institution like that Either launch an exchange or heavily get involved in in this space very very soon And then, you know trust and security is another big one So if you're an investor and you're thinking about these things and you're using some of these services You should deeply kind of you know, you should you should be very skeptical and you and and deeply think about What kind of security measures are these exchanges using particularly on the cold storage side? Okay, so This is really interesting if any of you are entrepreneurs and if you're thinking about okay, how do I get involved? how do I Participate and maybe some of you have financial backgrounds. Maybe some of you don't maybe some of your software engineers So the first first place I would really think about is vault management. So this is this is sort of like you know, you've got a bunch of crypto assets and You know, there's a bunch of services around that that Entrepreneurs can provide to help kind of like collateralize those assets for example Token ETFs and index funds are going to be really interesting. There's a couple guys in the US the Winklevoss twins kind of funny guys And they tried to launch an ETF, but they were sort of rejected. I think the reason they were rejected was because they Really kind of totally miscalculated how to go about doing something like that I think going public first and then talking to the regulator later was a terrible mistake I'm not sure they're the brightest guys, but you will see more and more ETFs coming up and then of course fiat token services So One of the things to look for that that'll be really interesting is when nation-states start tokenizing fiat So fiat is like Japanese yen or US dollars. I mean the traditional money as we understand it so you can imagine a scenario where Either a bank or a nation-state or perhaps an entrepreneur that works with the commercial bank sort of puts some let's say Japanese yen in an account and then issues tokens against those yen and now this becomes type of tokenized fiat the reason that's really important is because it sort of creates a pathway in and out of the crypto fiat world So Hosting ICOs and token trading You're gonna see more and more of these ICOs or token sales again as investors I would deeply deeply think about particularly on the security side who is sort of You know following regulatory guidelines and who isn't because that's gonna be a determination That's gonna help you determine sort of your risk profile So This is what I'm talking about when I say the tokenization of like the rest of the kind of global economy Which is much much bigger than than we realize. I mean the derivative market We actually don't know how big it is. It could be 700 billion to 1.4 quadrillion dollars like we don't actually know it's a massive Excuse me and then of course public equities fixed income derivatives real estate etc Infrastructure is another really interesting one. So Japan has I guess mega solar projects And so if some of you are entrepreneurs in the renewable space You can imagine kind of like doing an ICO to finance the development of a mega solar project Of which you get paid in yen Through these power purchasing agreements and you could like convert that yen into ether and distribute it out to the people That participated in your ICO and and if you think about capital allocation and raising capital in a traditional sense That can be quite hard at times But you know this sort of tokenizing You know this this would be a tokenized security that this model could potentially be extremely attractive not only here in Japan But around the world This is sort of less interesting maybe I'll skip through that But if anyone wants to take a picture, it's just kind of an arcade rough architecture diagram to give you an idea of How these things could work? You know so again thinking about potential opportunities value proposit like again Just think deeply about these things If you need some help and guidance around how to structure your thoughts, you know This kind of information is available online, but as the secure it you know as securities go on the blockchain You're going to see a tremendous tremendous influx of capital And many more sophisticated investors Particularly people that are in the traditional finance world and so as maybe recreational investors or new investors You know you want to really Set yourself up for success by deeply thinking about these things You know token analysis you can sort of do you know business review reputation overview technical review You could also do like a legal review So, you know whenever you see a project And maybe you're thinking about investing Don't just rely on what your buddy told you or what you see on like telegram This is another one you can you can sort of like take a picture if you want but on the crypto cash side I won't go too deep into that. You can sort of see how these things could work Token-based ETFs and index funds again, you can take a picture. It'll give you it'll give you a sense I've only got a minute and a half. So I won't go too deep into it Vault management also you can kind of get a sense So decentralized securities depository again CESD's we think are going to be a big deal I'm seeing a lot of pictures. That's good stuff. Okay, so that's me on Twitter if you want to find me And then I guess you know before before we wrap this up You know, I I think it's important to understand where we started where we are and kind of where we're headed Where we started was out of necessity If you think about something like Ethereum or even before that something like Bitcoin nobody would have ever given you permission to make Bitcoin Okay Yet it was totally necessary. It was like Fundamentally an element that has sort of changed the world as Bitcoin Performed beautifully as it sort of maintained its sort of structure Doing this one simple thing we started thinking about well How can we do other things in this blockchain context and so Ethereum emerged and and post Ethereum? We're starting to see Sort of that evolution continue things like DFINITY are coming etc And along the way people have been able to participate in this ecosystem Obviously with ICOs a direct participation. This is going to transfer You know, this is going to continue into the security space and I think it's one of the most exciting opportunities of our time So I definitely welcome it and hope you will too. So thank you very much


The concrete design for our highways, bridges, and other structures is intended to be of the highest quality. It should consist of approved materials that are correctly proportioned and mixed, and then carefully transported to the job and placed. In practice, however, the concrete ordered for the job may not be the concrete that's actually placed. At critical points during production, transport, or handling on site, the concrete's quality may be jeopardized. Bature mixer slips are not always a guarantee that you have the right concrete in the truck. For example, if wash water was left in the truck before it was loaded, the mix may be too wet, or the truck driver may decide to add water if the mix begins to stiffen. So it's important, and it's required, that the quality of the concrete be verified before the concrete is cast. Verification is provided by conventional control tests performed in the field. This presentation is the first of four videotapes on quality control of concrete on site. Here in part one and in part two are presented the conventional control tests for determining concrete quality at the job site. In parts three and four, you'll see new quality control procedures that have been developed by Sharp and others for testing concrete both before and after it's cast. So, here in part one, we'll look at sampling concrete and at the test methods for temperature and slump. In part two, we'll look at the test methods for air content and unit weight, as well as the procedures for making cylinders and beams. Our first topic, then, is sampling. Before any of the tests can be performed, a sample of the concrete is needed, a representative sample. The concrete to be tested has to be typical of the entire truck load. Sampling should be done according to AASHTO designation T141. The basic rule is this. Don't take the sample from the beginning or end of the discharge. Take it from the first one-third of the discharge, but never from the first two cubic feet. To obtain the sample, either the entire stream should be caught in a container, or the chute should be swung over to the side. The important point is to get the entire stream. Cutting the stream in half, like this, is unacceptable. The rim of the bucket will knock some of the large aggregate out of the sample. The sample should be mixed with a shovel just until it has a uniform appearance. Then it should be covered to protect it from the sun and the wind. Samples must not be allowed to dry out. One last point. Testing must be completed within 15 minutes after obtaining the sample. Now, temperature. The temperature of fresh concrete affects the rate at which concrete gains strength, the amount of strength the concrete ultimately acquires, and the porosity of the concrete. Checking concrete temperature is simple. It should be done according to ASTMC 1064. All that's needed is a standard thermometer, such as an ASTM liquid and glass type, or a metal immersion type. The thermometer is inserted into the fresh sample so that the temperature-sensing portion is submerged at least three inches. The concrete should be gently pressed around the thermometer so that the air temperature does not affect the reading. The thermometer is left in the concrete for two minutes, or until the temperature stabilizes. Then the temperature is recorded. The measurement must be completed within five minutes after the sample is obtained. The temperature of in-place concrete is measured in the same way. Now, the air temperatures during concrete construction are also important. The high and low air temperatures must be monitored daily. Next on the list is the slump test, AASHTO T119. This is by far the oldest and most widely used test to measure the uniformity and consistency of concrete. Variations in slump generally indicate that changes have occurred in the properties or proportions of cement, aggregates, water, or admixtures. The equipment needed for slump tests includes a standard slump cone, a standard tamping rod, a scoop, a base, and a ruler or measuring tape. The slump cone should be reasonably clean, especially inside. The surfaces should be smooth with no dried concrete on them. Also, there should be no major dents. A standard tamping rod is smooth with a rounded tip. Makeshift rods, such as Cut-Off Reinforcing Bar, are unacceptable. The base for the cone must be strong, rigid, and stable enough to support the tester as well as the concrete and equipment. It needs to be level and firmly supported so that it won't rock or bounce. The sample should be brought close to the test location and remixed if necessary until it looks uniform. The test is begun by first dampening the inside of the slump cone to keep the concrete from sticking to it. Then, the base is dampened as well so that it won't absorb water from the concrete. But no free-standing water should be left on the base. The cone should be set down on the base as close as possible to the sample. Next, the technician steps onto the footholds at the bottom of the cone and stays there. That's why the sample and cone need to be close to each other. The cone is filled by moving the scoop around the top to distribute the concrete as evenly as possible. The filling is done in three layers. Each layer should take up approximately one-third of the cone's volume. So the first layer should come up about two-and-a-half inches from the base. The second layer should come up about six inches. That's about halfway up the cone. And the third layer should overflow the cone. As each layer is placed in the cone, it's consolidated with a tamping rod. Starting at the perimeter with its rounded tip downward, the rod is inclined slightly to match the slope of the cone. Otherwise, the concrete closest to the cone's sides will not be properly consolidated. The rodding should go to the bottom of this first layer, but just tap the base. Each layer is rotted 25 times, with about half of the strokes made near the perimeter. A spiraling pattern should be followed as the rod moves toward the center of the cone. The strokes are distributed uniformly. As the rod is moved away from the perimeter, it's returned to the vertical. The second layer fills about half of the cone's height. It's rotted the same as the first with one difference. The rodding should just penetrate about a half inch into the first layer, not all the way down to the base. The third layer should overflow the cone. That way, the concrete stays above the cone throughout the rodding. If it drops below the top, the rodding should be stopped. More concrete should be added, and then the 25 spiraling strokes should be completed. And the rod should just penetrate the top of the second layer about one half inch. With the cone full and the rodding completed, the surface of the concrete is struck off by moving the tapping rod across it in a screaming and rolling motion. The concrete surface must be level and fairly smooth. Next, any concrete that is spilled around the bottom of the cone must be removed. Otherwise, it may keep the sample from slumping properly when the cone is lifted off. However, the technician must be careful not to move the cone and disturb the concrete. Basically, both sides of the cone must be held still by pressure on either the handholds or footholds until the cone is removed. To remove the cone, both hands are placed on the handholds and downward pressure is applied to keep the cone stable before the feet are removed from the footholds. Now the cone is pulled straight up, slowly and steadily, without twisting or tilting. The removal should be completed in about five seconds. Slowly enough that the concrete doesn't pull on the cone. The cone is then set on the base, next to the concrete, without touching the concrete or jarring the base. Immediately the tamping rod is laid flat across the top of the cone, extending over the concrete. A ruler or measuring tape is used to measure the distance between the bottom of the rod and the top of the concrete. The measurement should be made to a point that is directly above the center of the bottom of the concrete, not at the center of the top. The entire slump test must be accomplished within two minutes, as measured between the adding of the first layer and the measuring of the slump. And that's sampling temperature and slump. And the end of part one. In part two, we'll cover air content, unit weight, and the making of cylinders and beams. This second part of quality control of concrete on site will examine the test methods for air content and unit weight, plus the procedures for making cylinders and beams for compressive and flexural strength tests. To begin, air content test methods. The results of air content tests indicate the freeze-thaw durability of concrete. Air-entrained concrete with the specified air content performs much better than non-air-entrained concrete in freezing and thawing conditions. On the job, concrete can be rejected if its air content is not within the allowed range. The most popular method for measuring air content is the pressure method. Two types of pressure meters are available and are widely used. They are referred to as type A and type B and are covered in AASHTO T-152. With type A air meters, the equipment needed includes a calibrated type A meter, a tamping rod, just like the one used in the slump test, an internal vibrator, a rubber or rawhide mallet, a scoop, a strike-off bar, and a supply of fresh water. The meter consists of a measuring bowl having a capacity of at least two-tenths cubic foot and a cover assembly that includes a standpipe, a pressure gauge, and an air pump. The cover assembly also contains a number of valves and petcocks. The bowl and cover must clamp together to form a pressure-tight seal. As with the slump test, all the equipment should be clean and in good condition. It should be assembled near the concrete sample. The test is begun by filling the measuring bowl with concrete in either two or three equal layers and consolidating each one. The number of layers depends on whether the consolidating is done by rotting or vibrating. And the method of consolidation depends on the result of the slump test just performed. If the slump is less than an inch, vibrating is required. If it's more than three inches, use the tamping rod. And if it's between one and three inches, either method can be used. When the tamping rod is used, the bowl is filled in three equal layers. Each layer is rotted 25 times and the strokes are distributed evenly over the cross-section. The bottom layer should be rotted throughout its depth, but without forcibly striking the bottom of the bowl. After each layer is rotted, the sides of the bowl should be tapped sharply with the rubber mallet 10 to 15 times around the bowl's circumference. This will close any voids left in the concrete by the tamping rod and release any large entrapped air bubbles. In rotting the second and final layers, only enough force should be used to penetrate the surface of the previous layer about one inch. Then, the final layer of concrete is added without excessively overfilling the bowl. When the vibrator is used, the bowl should be filled in two layers of approximately equal volume. After the first layer is added, the vibrator is inserted three times at points evenly distributed over the cross-section. The vibrator must not touch or rest on the bottom or sides of the bowl and the concrete should not be over-vibrated. Such practices segregate the aggregate and lose some of the intentionally entrained air. The final layer is added without excessively overfilling the bowl. Then, it's vibrated the same way the first layer was vibrated. Usually, the surface has been vibrated enough when it's relatively smooth and looks glazed. The surface should then be struck off by sliding the strike-off bar across the top flange or rim of the measuring bowl. Then, the contact surfaces are white clean and the cover assembly is clamped firmly to the bowl. The lower petcock is closed, the upper petcock and funnel valve are opened, and water is added until it rises to about the halfway mark in the standpipe. The meter should be gently rotated and tapped with the mallet to remove any entrapped air that may remain. Next, water should be poured through the funnel valve until it stands at a level slightly above the arrow mark on the graduated scale. The funnel valve is then closed and the level is adjusted to the arrow mark by drawing off just enough water through the lower petcock. Next, the top petcock is closed and pressure is applied with the air pump until the gauge reaches the exact air pressure required. The required pressure is known from the calibration procedure. Now, the resulting water level is red, the bottom of the meniscus on the graduated scale. This value is the gross percentage of air entrained in the concrete, or H sub 1. Then, the pressure is released and the water level on the graduated scale is red. This value is the lag, or H sub 2. The air content of the concrete is the gross percentage, H sub 1, minus the lag, H sub 2, minus an aggregate correction factor, G. Determination of the aggregate correction factor using both meters is covered in T 152. The type B test requires a calibrated type B meter as well as the same equipment needed for the type A test. The first step is to fill the bowl with concrete, consolidate it, and strike it off, the same as for type A. Then, the flange is wiped clean and the cover is clamped on with both petcocks open. Water is then injected through one petcock until it comes out the other petcock. With both petcocks open and the air bleeder valve closed, air is pumped into the air chamber until the gauge hand is on the initial pressure line. To stabilize the gauge hand at initial pressure, air is pumped in or bled off as necessary and the gauge is tapped lightly. Next, both petcocks are closed and the thumb lever is pressed down. This releases the air into the bowl. The sides of the bowl are tapped sharply with the mallet and the gauge is tapped gently with the fingers until the dial hand stabilizes. This is the gross air content percent. From it, the aggregate correction factor is subtracted. The result is the net air content percentage of the concrete. Now it's time for the unit weight measurement of fresh concrete. The unit weight, or density, is determined simply by weighing a known volume of the concrete according to AASHTO T-121. The same equipment used for air content testing is needed, as well as a measuring container or measure, a balance or scale, and a strike off plate. The balance or scale must be accurate to within 3-10% of the test load. The measure must be a watertight cylindrical container whose capacity depends on the size of aggregate used in the concrete. For one-inch maximum size aggregate, a measure with a minimum capacity of two-tenths cubic foot should be used. If the aggregate has a maximum size of one-and-a-half inches, the measure's minimum capacity should be four-tenths cubic foot. And for two-inch maximum size aggregate, the minimum capacity should be five-tenths cubic foot. Since the air content meter's bowl has a capacity of two-tenths cubic foot, it can be used as the measure when the concrete contains one-inch maximum size aggregate, as is becoming more common in pavements and bridges. The first thing to do is place the empty bowl and strike off plate on the scale or balance and record the weight. The bowl is then filled in three equal layers of concrete, with each layer properly consolidated. Consolidation requirements are the same as for the air content test. If the slump is less than one inch, you vibrate. If it's more than three inches, you rod. And if it's in between, you have the option. The concrete surface is struck off and finished using the strike off plate. The bowl must be exactly level full. Then all excess concrete is cleaned off the outside of the bowl, and the filled bowl and strike off plate are placed on the scale or balance. The net weight of the concrete is determined by subtracting the empty weight of the bowl from its filled weight. To calculate the unit weight, the net weight of the concrete is divided by the calibrated volume of the bowl. The last topic is the making of concrete cylinders and beams on site for subsequent compressive and flexural strength tests. Other than the molds, all needed equipment is available from the other tests we've covered. The sizes of molds are based on the concrete used and on specific project requirements. To begin, the proper molds must be on hand and clean. The concrete is placed in the mold using the scoop or trowel. Then the tamping rod is used to distribute the concrete evenly across the full area of the mold before starting consolidation. The number of layers required to fill the mold depends on the mold size or depth. Table 1 of AASHTO T23 details the specific mold requirements. For common molds such as cylinders with depths up to 12 inches, the concrete is placed in three equal layers for rotting and two equal layers for vibrating. For beams with depths between 6 and 8 inches, the concrete is placed in two equal layers for rotting and just one layer for vibrating. Selection of the consolidation procedure depends on the slump, just as it did for the air content and unit weight tests. Less than one inch, vibrate. More than three, rod. In between, optional. When rotting is used, the number of strokes is usually 25 for the most common molds. Table 2 of AASHTO T23 gives the requirements for other molds. After each layer is consolidated, the outsides of the mold are tapped lightly 10 to 15 times to close any holes left by the rod or vibrator. When beams are made, the tapping of the mold should be followed by spading the concrete along the sides and ends with a trowel or other suitable tool. To finish the cylinders or beams, a small excess of concrete is added to the surface, but not more than a quarter inch.  Normally, a wood or magnesium float is used to finish the surface. But a steel trowel is used if specified. Immediately after they're finished, the mold should be covered to prevent evaporation. Polyethylene sheeting is usually used for this purpose. Alternatively, wet burlap may be used, covered by plastic. In this program and in Part 1, you've seen the onsite procedures for sampling fresh concrete, testing it for temperature, slump, air content and unit weight, and making cylinders and beams for compressive and flexural strength tests. In Parts 3 and 4, you'll see new concrete testing and monitoring procedures developed by Sharp and others. The careful following of proper sampling and testing methods greatly enhances the quality control of concrete onsite.

Bad habits always die hard. If you're watching this video because you think we have some shortcuts, well, we don't want to get your hopes up. Instead, we're here to offer our support and some helpful tips. There are five ways to stop reinforcing bad habits and make good ones instead. One, identify what triggers them. Psychologist Robert Tybee says that when you can identify your triggers, then you can push back. Whether it means cutting down on junk food or starting your homework earlier, there are ways to spot what makes you jump back into the dreaded rabbit hole. Having chips and ice cream in your pantry and fridge can make it tempting to resort back to your old ways. Instead, we recommend getting rid of them and replacing them with healthier snacks. If playing video games or browsing the internet makes you start your homework late, we recommend putting your games away and temporarily deactivating your social media pages. That way, there are less distractions to work with. Two, accept that there are obstacles ahead. It's not going to be rainbows and butterflies, that's for sure. Art Markham, a professor of psychology at the University of Texas, states, people don't take the obstacles they're going to face seriously enough when they set out to change behaviors. This makes it very easy to become discouraged along the way. To avoid being disillusioned, Markham recommends thinking of all the things that can go wrong and preparing ways to overcome them. Always have a plan B. Set realistic goals and accept that failure is part of the process. Three, create a reward system. Who said ending bad habits has to be all work? Unless you're working hard, you might as well play hard too. Every time you pull back from your bad habits, reward yourself. Whether it means going to the spa or baking cookies after a long week of eating healthy. Give yourself a well-earned break. On the flip side, however, if you cave into your bad habits, it's important to set some rules to help you get back in line. Punishment doesn't have to be brutal, of course, but if you catch yourself giving into that bag of chips only on day two, drop and give yourself 20. Feel free to brainstorm your system with a friend or family member to make things more fun. This will also hold you more accountable for your actions. Four, make changes slowly. Patience, young grasshopper. Instant gratification is tempting, but in this case, gradual progress will pay off better long-term than hasty results. Instead of cutting all your bad habits immediately, make changes slowly to help your body adapt better both physically and mentally. Rome definitely wasn't built in a day. Moderation is key. Five, don't let failure be a reason to give up. Expect to fail along the way, but the most important thing is to keep going. Often, we're too hard on ourselves when we slip. Instead of beating ourselves up over the mistakes we make, we can see them as learning opportunities. Remember, you are stronger than your temptations. Nowadays, it's so hard to find time in our busy lives to take a moment to sit and learn something new or something we are curious about. Most people enjoy reading, but struggle in finding the time to do so. But with the help of Blinkist, you can change that entirely.
