So, by now you have seen that to calculate the pecking fraction of any unit cell, you need to know its A effective, the radius of the atoms that make up the unit cell and its edge length A. Now, if you slightly rearrange this relation and write r cube by A cube as r by A cube, then you'll realize that even if you don't know the exact value of r and A, but if you simply know the ratio of r by A, then we'll still be able to calculate its pecking fraction. Sounds interesting, right? However, the really interesting bit, and the real reason why I'm writing it as r by A, is because it turns out that this ratio is constant for each of these unit cells. For example, the simple cubic unit cell has a r by A ratio of 1 by 2. And what it really means is that it doesn't matter what size of atoms you take. As long as you arrange them in the form of simple cubic, the ratio of the radius of the atom to the edge length will always remain the same. Cool, right? The same goes for BCC as well as FCC. As long as you arrange atoms in the form of BCC, the ratio of the radius of the atom to its edge length will always be root 3 by 4. And similarly for FCC, it will always be root 2 by 4. So in this video, we will try and figure out how these ratios came about, why they turn out to be constant, and ultimately use them to calculate the pecking fraction of each of these unit cells. So let's dive right into the video. Let us for a moment consider metal atoms to be circles rather than spheres. Now in a metal crystal, these metal atoms are not free, but are instead bonded to each other by some metallic bonds, right? Now let us assume that these atoms are bonded in such a way so that they form a square unit cell. Now in such a scenario, the side of the square or the edge of the square will always be equal to 2 times the radius of these circles which make up the square, right? So the side A will always be equal to twice R. So even if you don't know the exact values of A or R, we'll always be able to say that for a square unit cell, the R by A ratio will always be equal to 1 by 2, right? It doesn't really matter if these circles were bigger or smaller. If they form a square unit cell, the atoms at the corners will touch each other. So A will always be equal to twice R and R by A will always be equal to 1 by 2. Now if we had a scenario in which the circles did not touch each other, then the side A will not be equal to twice R. So we won't be able to figure out the R by A ratio just by looking at this configuration. In this scenario, we need to know the radius as well as the side to find out R by A. However, having said that, we should remember that such a scenario is not possible when it comes to a metal crystal. These atoms, they cannot lie just hanging in space. They have to be bonded at least to one other atom. Let us now take a look at a different configuration of atoms. This is a squared centered unit cell, right? This can also result in a valid metal crystal as each of these atoms are bonded to at least one other atom. We don't have any atom that is hanging around in space. So can we figure out the R by A ratio just by looking at the configuration? Well, let us see. Well, out here the atoms at the corners, they do not touch each other. So we can't find any relationship between A and R from here. But if we look across this diagonal, across this line, we will see that all these atoms, they touch each other. So the length of this diagonal, length of diagonal can be written as the radius of this circle R plus the diameter of this one, which is going to be twice R, plus the radius of this circle R. So the length of the diagonal in terms of the radius can be written as 4R. Now, if you look at this triangle, let me name this as ABC triangle ABC. We will realize that this is a right triangle where AB is equal to BC is equal to side of the square A. So now if we use Pythagoras theorem, we can say that AC square will be equal to AB square plus BC square. So AC square will be equal to A square plus A square, which is 2A square. So this implies that AC will be equal to root 2 times of A, right? So the diagonal AC can always be written in terms of the edges A as root 2 of A. So therefore, if we equate these two relations, then root 2 of A will be equal to 4R. So R by A will always be equal to root 2 by 4, right? In other words, it doesn't matter whether these circles are smaller or bigger because the atoms will always touch each other across the diagonal. So the length of the diagonal will always be 4R. And because the diagonal of a square is always root 2 times the edge A, so R by A will always be equal to root 2 by 4. We are now finally ready to calculate the packing fraction of different unit cells. So for a simple cubic unit cell, the A effective comes out to be equal to 1. What about R by A? Pause the video, look at this figure and try to come up with an answer. Well, R by A is going to be equal to 1 by 2, right? Because the atoms along the edges, they are touching each other, so A is going to be clearly equal to 2R. So the packing fraction will be 1 into 4 by 3 pi into 1 by 2 cube, which if you do the math will come out to be 0.524. So in terms of percentages, the packing efficiency of this cube comes out to be equal to 52.4%. Now I'd like to add out here that a crystal is not made of a single unit cell, but instead it contains infinite unit cells. Now all these unit cells are identical to each other in all respects, so the packing efficiency of every single one of them will be 52.4%, right? So we can now go ahead and say that the overall crystal also has a packing efficiency of 52.4%. So arranging atoms in the form of a simple cubic occupies only around 50% of the available volume and leaves the remaining 50% as gaps. Not a very efficient system if you ask me. Let us see what happens for the FCC. What would be the R by A ratio for FCC? Pause this video again and think about the answer. Well in FCC the atoms at these corners, they do not touch each other, right? So we won't be able to figure out a relationship between A and R from out here. So what do we do now? Well if you look at these atoms, the one across this face will call this the face diagonal. All the atoms across this face diagonal touch each other, right? So we might be able to figure out the relationship between R and A from out here. Now this line is the diagonal of this square. So we have seen that the diagonal of a square will come out to be equal to root 2A and this will also be equal to 4R as these spheres are in contact with each other. So this is going to be equal to 4R. So the R by A ratio will come out to be equal to root 2 by 4. Now it doesn't matter if these atoms are big or small. As long as they form FCC the atoms along the face diagonal will always touch each other. So this distance will always be equal to 4R and because the diagonal of a square can be written in terms of A as root 2A so R by A will always be equal to root 2 by 4. So if we now plug in the values for the packing fraction. So R by A will be root 2 by 4 whole thing cube while A effective for FCC is going to be equal to 4. So 4 into 4 by 3 pi into root 2 by 4 whole thing cube. So now if we do this calculation we'll find out that the packing fraction is comes out to be equal to 0.74. So arranging atoms in the form of FCC leads to 74% packing efficiency. So almost three fourths of the available volume is occupied and only one fourth is left as caps. Let's come to our last case the body centered cubic. In BCC A effective is equal to 2 but what is the R by A ratio? How do you calculate the R by A ratio in BCC? Well the atoms along the corners do not touch each other so we won't be able to calculate R by A from here and if you look across this face diagonal you'll realize that this atom doesn't lie on this face but it's actually inside right. So this distance is definitely not twice R. So the face diagonal cannot be written as 4R. So how do we find out R by A? Well we need to think of some line which can be written in terms of R right? Pause this video and see if you can find out such a line. It can be an edge or a face diagonal or anything else. Now in a BCC if you look closely we'll realize that the atoms along this line they touch each other. So this line is called the body diagonal and atoms along this body diagonal they touch each other. So the length of this line can be written as R plus twice R and R. So this line can be written as 4R. Now to find out R by A we need to be able to write this R in terms of A right? So we need to be able to write this line in terms of A. So how can we do that? Well in this cube even this line is the edge length A right? And now if I join these two points I'll have a right angle triangle out here. Let me name this triangle A, B and C. Now in this right triangle ABC, AB is A, SC is 4R but I don't know the value of BC. If I can somehow figure out the value of BC I might be able to relate A and R using Pythagoras theorem right? So how do we figure out BC? Hmm well if you look at the base of this cube this is a square right? And this BC is the diagonal of this square. Now we have seen that for a square of sides A the diagonal can be written as root 2A right? So in triangle ABC, AB and BC are the sides of the triangle while SC is the hypotenuse. So using Pythagoras theorem we can write 4R whole thing square equal to A square plus root 2A whole thing square. So this implies that 4R whole thing square will be equal to A square plus 2A square. So this will be equal to 3A square right? So we can write 4R to be equal to root 3 times of A and this implies that R by A will come out to be equal to root 3 by 4. So in BCC the R by A ratio will come out to be equal to root 3 by 4 and it does not matter if these atoms are big or small as long as they're arranged in the form of BCC the atoms across the body diagonal will touch each other. So the body diagonal can always be written as 4R and this body diagonal can be written in terms of A as root 3A. So R by A will always come out to be equal to root 3 by 4. Now if I plug in these values then the pecking fraction of BCC will come out to be equal to 0.68. So in BCC the pecking efficiency is 68%. So to summarize the pecking fraction of FCC is 0.74 that of BCC is 0.68 and that of simple cubic is 0.52. So FCC has the highest pecking efficiency amongst all the cubic unit cells.


Hello everyone, my name is Andrew Lisik. This is a continuation of kind of something we started in Austin and Barcelona, just kind of our continued evolution of what AT&T challenges of dealing with CICD for our scale deployments and I'm Andrew. This is Larry Rinsing and this is Malin that has joined me. So next slide. Biggest challenge since post-Barcelona is what we've been banging into people's heads is really a cultural transformation. That's the people problem has been one of our biggest challenges of taking a credibly skilled DevOps engineers and Taking them back to thinking of a zero-touch cloud provisioning mindset through the labs and through deployments production deployments maintaining consistency back up I'll bring the mic up. Okay LCM fuel life cycle management. These are some of the things we've introduced For people that have been kind of following us. We are a fuel nine dot x shop With the Moss distribution for the AIC 2.x reference architecture, which is a virtualized reference architecture We host two different kinds or really three It's kind of two different larges for specific VNF workloads and then a medium type of site deployment for a workload Which face it which introduces a quite a few challenges from a delivery standpoint But what we've done is we've tried to drive consistency through our pipelines and automate everything Our big challenges are greenfield brownfield upgrades. That's a deployed site and upgrade it with things like kernel upgrades or Open stack component upgrades version upgrades things like that. They're the heavier weight things contrail upgrades were contrail 3.x shop, too And then we've done moved into a release candidate model to allow us to do sort of rapid patching within those sites using puppet and fuel nine dot x and Then our rapid patching which is you know, even a little bit lighter weight We can turn those things around in like an hour Out into production and control that through a canary which we call sills our user acceptance sites before our production application To get assurance out there then rack expanses or something else We needed to mechanize because we need to grow compute nodes quite a bit Some of the other things we've touched on that have been really valuable to us have been able to certain components in our infrastructure that we deploy We automate the upstream sinking So it's just mechanized through Jenkins that we pull down as kind of a few think of a maintenance release So we can kind of consistently get in and choose what things we want to cherry pick in our deployments more rapidly than waiting for the Entire product to go say GA or something if we need a patch Then the AVT emulated scale lab one of the challenges we faced In our deployments when we were using the various products is once we got to three to five hundred nodes We would see some of the some of the infrastructure show stress and would flex and so We just to be able to do something consistently and rapidly we introduced in this emulated Scale lab we can talk more about if some of us have dropped by afterwards. It's literally just made of three Dell 730s and With two of them having 150 emulated VMs, and then one acting as a control node It allows us to do some of those bulleted items there to kind of do some sanity Consistently kind of over our deployments and we can kind of observe times and you know alert when we start seeing things get out of whack if somebody's introduced some code that Introduces a scale problem. We'll have some historical data to flag. So jump to the next slide Some of the stuff we were talking about was we look for consistency. It's really really important to us So YAML describes our deployments We use a Jenkins mechanized node that we Actually, it's just a slave node and we've containerized it and we use that exact same node From our avi from our basic the farthest left CICD labs, which we have dev labs We have RC labs system test labs and up to SILs. We use the exact same tools exact same processes To make sure that we can sort of what we do in these same things is that we have a repeatable consistent site We tried in 2015 to deploy many many sites Where we had a lot of dev ops ninjas having to account for things and we had to eliminate that as much as we could because we deployed it, you know 80 sites and Across the world and you know, we're consistently deploying more of those this year. I think we have another 60 on the books plus 60 total more this year, so Maintaining that as a challenge and consistency and automation is the only way to achieve that. So That's what we've introduced this concept of full CD And full CD is literally like I said just using Jenkins to Mechanize the entire deployment procedure and all four of those items on before that were listed before those different levels of Jenkins automation and the pipelines and Introducing our quality gates within those pipelines. They're almost all voting gates for us So we do regular coding gates as well as deployment gates. So when we're actually deploying We can stop a deployment early in our labs before it goes anywhere if it fails And we have multiple dimensions of those tests that we're kind of always evolving and I think that's it for what we've achieved since then Thanks, Andrew And you talked about gates and this side will this slide will give you an idea of what gates we have in our CSED and deployment workflow Right from the point when someone merges a piece of code to the point where it hits That's at step one and to the point where it hits production. That's in step eight. So Two to seven are all the gates that piece of code has to go through before even it gets deployed in production Right. So we have some of the basic ones like in two you can see the usual syntax checks unit tests Packaging we don't also run some package checks to just to be proactive to make sure it will be the piece of code is going to be deployed successfully we have our nightly sonar cube Scans which are the test coverage scans. We have 45 scans that we have fully automated Which which which are basically security scanning to find vulnerabilities in the code Step four we have the nightly avd avd is a we call it a IC verification test. It's It's integration test framework based on fuel DevOps and fuel QA Once it's passed and yes, we use we use OSTF which is open stack test framework and of course Tempest for our automated verification Step five full CD Andrew mentioned full CD which is Which is also one of the gates Beyond that these are there is a there is something called at least candidate integration lab where developers can Test their piece of code in as it would be deployed in production System test in step seven does their own automated testing and That's I mean that's that's all it takes to hit production So it's it's it's a bunch of stages that you have to pass until until you can get there Here are some of the matrix that will give you an idea. I mean I do mention we are in more than 80 plus production sites right all over the world Let's give you an idea of the scale that we are operating at right and these are again. These are old numbers highlighted some of one sums with some important ones in the red Like we with full CD. We are able to deploy in eight hours, I Think I'll let you see if I think we're running out of time. So I'm gonna pass it on to Larry Yeah, so it's it's no secret at this point the benefits to containers and things like Kubernetes provide Internally at AIC we have an effort to containerize our local control plane leveraging the open stack helm project and Using helm to deploy our open stack control plane The benefits this is pretty much common knowledge Kubernetes provides that abstraction layer that sort of separates the hardware from the actual software running if you don't really have this Snowflake syndrome going on So this is an example of our workflow the top one is if a developer was going to make a modification to a project like Keystone if we push a bug fix Assuming it passes like the pep 8 unit tests. We're gonna perform a docker build Stand that container up do some basic health checks to make sure it doesn't fall over on top of itself when you bring it up and then tear that down Pass that docker image ID to another project called armada, which is going to deploy that in a helm chart Once we have our full open stack cloud up we're gonna run tempest and Rally against that to get our integration test and benchmarking results If that all goes well, we're gonna tag that as a release candidate and then push that out and then the second pipeline Beneath is if we were to make a modification to a helm chart, so we would Push that up bring up a single node Kubernetes instance using something like kubadmin package up our helm chart do a dry run to make sure there are no syntax errors and Pretty much the same from there deploy it again If you want to contribute to open stack helm or armada of the tools we talked about The github links are there if you want to hear more about open stack helm We have another session on Thursday that will be presented by Alan Meadows and Brandon Joseph the information is there So we'll be outside if you have any Q&A


Well, after almost six years of sitting vacant, Bemidji's former Pomita store will see a new tenant. Business and building owner Rob St. Michael says it's an ideal location and he will be moving his furniture store from Union Square in downtown Bemidji across the parking lot to the old Pomita location. St. Michael bought the building last October and will be using 60% of the building, leaving the remaining part of the building available to rent. Demolition on the interior began yesterday and full renovations will begin in mid-April. St. Michael furniture plans to hold a grand opening at its new location sometime in early August.

Mae'n meddwl o'r ddilyn wedi'i rhan o'r ddilyn o'r ddilyn o'r ddilyn. Felly, mae'n meddwl o'r ddilyn the most expert in, and people who are really participating in them probably have much more informed views. So, on the Debian wiki, there is a page called Local Groups, and if you look at this page, then this map is not there at the moment, but that's a map showing all the places that we claim to have Local Groups. And if you believe that, it looks very impressive. I mean, as I expected, it's more or less where we have concentrations of Debian developers, kind of where people come to Debian from as well. There's a microphone just behind you. In that Local Group did appear, so yeah, there are people in many places. I mean, in fact also, there's a lot more people. This is people who've listed themselves as a local group. Lost people just list themselves, for example, on key signing pages. So, if you're an active Debian developer travelling around, or a Debian contributor travelling around, and you make an effort to contact people, often in many more places in the world, you can turn up a group to meet for a chat or key signing, whatever. That's what I did. I just found their email list on the wiki and contacted them, and I met every one of them, so it works. So, as I said, this looks quite impressive, but in reality, many of these groups are dead or never really got started. Someone just added it on the wiki page because it sounded a nice idea, but the group is just, well, there are some people, maybe, who are physically based in that location, but they don't meet or really do anything. They just exist. And even when they do meet, often in what happens in practice, is that the details are only visible to people who are already involved. That, for example, another person from outside is turning up and they emailed a few people. In Edinburgh, we had for a while some group of Debian people meeting, but all that happened was one person was sending an email to the other people he knew were likely to come. So, probably actually there were lots more people in the city who might have been interested, but because of the way it was being organised, it wasn't really visible if you weren't, didn't already have a connection with the group. So, to know what people's interest or background or experiences who here does have some kind of thing that could be described as a local group or local meeting or something that they're currently participating in or have done before. Kind of. So, who definitely doesn't have any Debian connection around where they're living. For those just out of interest quickly, for those people, did you have anyone you knew who was involved in Debian before you started or you just found Debian from the internet and got a connection that way? Or do you think it would have helped you if there was some more visible Debian people around or anyone have an opinion? I had some friends that used Debian and I had some friends that used Debian and that's how I started to use it like for many years ago. And now I'm looking for other people that can do something together maybe. And then from, I don't know, maybe also if people are slightly awake, then the ones who have been involved in some group maybe a couple of people at least would like to say something about what their group, I mean what form does their group take because this again, these things vary, some of them are very organized, have talks, have regular meetings, some is just, people know that a few friends exist in the city or in the same country or whatever. Does anyone able to describe what their experience is? So I'm just a guest at my local group I have to say because I'm an uploading contributor. And so this local group is stationed in a hack lab and I think also they meet over the hack lab email list so it's not really open to everybody who is in the same city but they meet on a regular basis. I don't even know if they are on the wiki but I will check. Anyone else? So in Switzerland we've got a local group in Zurich which has a fixed monthly meeting. There is also a French speaking region of Switzerland and they have ad hoc meetings so maybe three or four times a year that someone calls for a dinner and they get together. And those are all announced on the local mailing list and there's also a site that's run by the Linux user groups of Switzerland with a shared calendar where those events are announced. In the Washington DC area we've had occasional ad hoc meetings though not so much lately, mostly just when somebody else is coming to town. I've got a mailing list in an IRC channel though I don't know how active the ladder is because I don't really do IRC much myself. Well, I am part of a Catalan group but it's not a local group because we are all in Catalonia and it's quite wide and we are not doing a lot of things. We wanted to meet each six months, it's not a lot but it's not a city group but the last time we couldn't do it. We wanted to do it but we have no efforts, enough efforts and I don't know how to... because the problem is that at least in Catalonia, Ubuntu has local communities very strong and there are a lot of people but we have no efforts to move things. In Washington DC area we've had one or two with the local Ubuntu community as well but we haven't done that lately either. So maybe this is a... since that question has come up of other kinds of groups that happen and so on, maybe that's a good moment to compare across. First of all, this is what the Debian local groups page has. It has this and then if you scroll down, there's listed by continent and country, some text format, standard form. There's not really any clue in any case whether this is recent information or was put there ten years ago or whatever. I'm not sure if you're a new potential contributor, this is necessarily... looks particularly welcoming way to present it but also it's not necessarily very visible. This is in a page of the name local groups in the wiki but you kind of need to know that exists to look for it. So for example, Ubuntu has been mentioned, pushes this somewhat more and then again this... it's nothing... this is not a kind of JavaScript filled fancy website or anything, it's not anything that Debian would reject necessarily but it's a bit more of a welcoming format. So one question is even apart from changing what any groups are doing or encouraging more, maybe we should think about having some more friendly kind of pointers to this somehow. Actually, sorry, on Ubuntu, is anyone here experienced slightly with what Ubuntu are doing to comment on that because it has been something that they've done much more of trying to have these local communities. Is anyone willing to admit to knowing enough about Ubuntu to comment on that? You said you had some meetings with them, so maybe you know slightly. I know. It was... not deeply about what they're up to. My understanding is... it's really been a couple of years, I mean it's just hanging out, so I'm going to give a lot of detail there, sorry. So again, Fedora have a similar kind of thing actually. So one thing to note about both... well, for example, with Ubuntu and Fedora is that they have a kind of more top... as you might expect, a more top-down hierarchical way of doing this, that they've divided up the world into kind of marketing territories and people are appointed to be in charge of those territories and then they're allowed to authorise subgroups within that and so forth. I mean I think for... maybe I don't know if any people disagree, but I would have thought probably for... although we might want to have some more help towards local groups and so on, I don't think we necessarily want to have that kind of structure for a Debian thing. Obviously we just allow groups to develop where people want them, which again, I mean it's also... it will depend where in the world people are, what is a local group. If you're in a place where there's a huge number... if you're in Germany, where there's a lot of Debian developers, then probably people's local meeting might be just their city. If you're in a country where there's three developers in a country, then probably the meaning of local in practice might become a bit different. This is the information on KDE, local in-home community, so actually we're not... I wouldn't say we're the worst here. Somewhere in... buried amongst us there is information on different countries, but it looks a bit like... it does look like a... just boring information. This is Arch Linux, so again, at least on one part of the website, we can say we're ahead of Arch Linux, if and if not on some of the documentation fronts. They just have... they say they have a group in... probably a group in Düsseldorf, a group in Berlin and Luxembourg. So again, I mean we're not doing so badly maybe. There are actually quite a lot of groups. At the moment we don't really... it's not something that Debian has really actively encouraged, so it's quite surprising that there are so many that claim... at least claim to exist currently. So this is also some information from GNOME. So one interesting thing with them actually is that they have, unlike the other people, a more clear guideline on what counts as a local group for them, is just a question that would apply for... comes up for Debian as well. So imagine we do want to encourage more local Debian groups, then you have to say, well, what is it? I mean, we don't... probably we don't want to just become a... encyclopedia of existing Linux user groups. There's not much point just to duplicate that information. So you probably want to say there is something that marks out a Debian local group as being somehow connected with a Debian, not just people who like computers or something. So what GNOME say is... where is it in here? Yeah, the groups must focus on GNOME or the GNOME community. Sorry, it does a screenshot now. I tried to make it big, but apparently not big enough. I can reload or something, but I'm just reading it out anyway. My Wi-Fi is so terrible in here. I took screenshots of the websites because they knew I wouldn't work. They could be a separate organization. They're allowed to be a subgroup of a log, for example, but it has to have a kind of visible existence of its own. One that probably would share with what we might want for Debian is it should be somehow about free software. Then they say they want a contact person and they should follow the overall GNOME code of conduct. Somehow there is something we probably would follow more or less if we wanted to set ideas about what a Debian group might be, the same kind of parallel. So stepping to a different side for a moment, and one question is it will. Again, some of these groups that may or may not exist at the moment do have regular or physical meetings, and it does seem to be that where that happens it's kind of a useful thing, although other ones just have a meaningless example. There's someone... Hi everyone. I'm a bit out of breath. Sorry I was late. Many thanks to the video team because I was listening to the stream the whole time while driving. Emphasis on listening. So I was part of the co-founders of the Ubuntu local team here in Quebec which grew to around 300 people at every release party was crazy. I started a few others in other countries. I'm originally from Colombia. So I'm trying to apply all that experience and knowledge and partying to getting together a welcome team for Debian. And there's a BOF right after this in Woody if you're interested. So regarding physical meetings I think that's the most important, the single most important part. And in Ubuntu at some point even if you think the Ubuntu was very strong and very wide and accepting and including we reached a limit where people wouldn't come for three hour events to geek out and bring their laptops and show off and so on. And it was very welcoming, family friendly as we said. But I came up with a very simple idea that seemed absurd at the time and has grown quite a bit. And it's the Ubuntu hour. And so we removed everything. So we kind of joked about this and we said what do we hate the most when we go to one of these meetings? Even if we love seeing new people and people we know and getting together and sharing and so on. And for some of us was the time we started to grow up and get older and get families and other responsibilities. For some other people was just a geeking aspect of it. They hate having to share or even pretend that they know anything about anything. Some people just know absolutely nothing about it and they're just curious. The relatives, the family, the colleagues and so the Ubuntu hour had, I think, or still has three requirements was trying not to bring any machines. It's only an hour and it can be one person.   If someone else joins, well, then you're three. That's a 30%, 33% increase and so on and so forth. And if no one else joins, then that's it, you have an hour of peace and self introspection and whatever and you leave and that's it. And the only other thing was to repeat this on a weekly or monthly basis. It's just weird how people just adopted this and Canonical made it an official resource and now there's a tool to add your own Ubuntu hours and whatever. It started as a weekend. So my first suggestion would be if we're going to go towards the social solution for this problem would be keep it very, very, very simple. Even the signs, all that stuff that comes with organizing something, having coffee, food and so on. Don't worry, just advertise. You are going to be available in an hour wherever. And we actually had Ubuntu hours in neighborhoods. Forget about countries. It was like there's Ubuntu Montreal hour in this neighborhood and in this other and people loved it because they didn't even have to take the bus or anything like that. So yeah, if anyone's interested I almost forgot about local groups in our BOF, there's no mention of it and I just noticed this this morning. So yeah, come and see me and I'm going to be here until I mean, I live here in Montreal so I'm going to be at least here at Depeganth until Saturday, but let's meet and chat. I mean, certainly I've seen that for a couple of the Debian local meetings that do go on where it just seems to, if someone can say once a month they're going to be in this cafe at this time, whatever and that person just makes a commitment to go then something will... Right, and we actually even removed the commitment part of what you just said and sometimes I wouldn't show to my own Ubuntu hour thing in my neighborhood and people would go. Sure. And just because two people would show up and they knew... Yeah, I think it's just that if it's only one new person who shows up then they may feel a bit lost, but... And if you look at Ubuntu thinking back something that feels contrary to the Debian community is every Ubuntu team had a team lead and co-lead and people that were clearly kind of above everyone else. Do you think that's useful or... It takes someone to do the dirty job at the beginning, I think and Canonical actually got people to do a lot of things with t-shirts and free CDs. A lot of things. And then that worked. Yeah, oh and stickers. So yeah, those three things were huge. So can we get sponsors to give us that and start the Debian hour or something like that? I'm thinking about it. So I mean another thing, again I think what you're saying about having it every week or every month is certainly I know myself when I see for non-Debian things other groups happening in Edinburgh say quite often I see the meeting after it already happened. But if I know there's another one in a month's time for example I can put that in my diary and attempt to remember that time. So one of things is kind of harder to get involved. Can I just respond to that? Just on the idea of a team lead in Debian someone can lead something just for one meeting. Yeah, when Morae stands up here today for an hour he's leading this event but someone else might propose an event on the same topic at the next EPCONF. So it's not that we don't have people leading things it's just the duration of that role isn't fixed or formal. But leadership still happens in Debian just in a different way. I just wanted to suggest bringing up the website used to advertise the events in Switzerland. Do you want to bring up your browser and I'll give you this? Good luck, I see. What is it? Which one do you want? So it's frytermine.ch F-R-E-I-E so in dwych. F-R-E-I-E- termine T-E-R-M-I-N-E .ch Oh, it's working. Yes. So if you go to the right on the right hand side there's a key with the different colours what they mean. So there's a colour for Debian Treff Treff is German for meeting so Debian Treff is Debian meeting Zurich and there's another colour for FSFE meeting so each one has their colour and if you look in the calendar you can see them, you can go forward a month further down on the right there's a filter and you can get it in eye calendar format into your thunderbird or into your phone or whatever you use. So this is just one example in the German speaking region of Switzerland but this could be copied by groups that want to do this but I mean for me personally I am not a person that goes to a meeting at a fixed time every month and it's the same with other things like I don't commit to going to like a class at the gym at a fixed time every month I prefer to do what I'm doing and then whenever I finish that day I'll go out on my bike or something I don't have a fixed time for doing something like that I like to have flexibility and there are some people in the community that have the same feeling with Debian that they just do the Debian stuff when they feel like doing Debian stuff other people like to have a structure like this to have a monthly activity so the same thing won't work for everyone some new participants may also like being able to look at something like this and see where they can join very quickly even without being on the mailing list so some people are afraid to send an email asking for key signing or to say that they're visiting but if they see something like this and they can see where they might meet people they'll just show up so I think, yeah and has anyone else seen anything like this in other regions this kind of calendar you mean yes there is something like it in Edinburgh certainly one other idea I had just with that is that maybe some tools like say the wiki that we use for Debian maybe someone could develop a plugin for events so that when people put events in the wiki it would generate an eye calendar output that could be aggregated by sites like this can you bring back your browser since it seems it's working just open a new tab and I'll let's try this agenda in French sorry I can't hear it A, G, E, N, D, A oh yeah G sorry not J oh I can't see D, U L, I, B, R, E so agenda agenda du libre dot qc dot ca and this country level domain name can't be registered anymore it's for Quebec so this is pretty much the same and well very similar to me if you scroll down completely there's tags in the middle of the page at the bottom in the middle yeah so kind of like what you said for the colors and at the very top of it you will notice there's Switzerland at the right and I'm pretty sure it's empty because it's French, Swiss so we should talk recently on the there's a free software foundation mailing list I can't remember the exact list but there's a big discussion thread about centralizing the free software activities calendars what you see here was originally started in France in Quebec province we rewrote it of course and then we went back upstream and then we combined the source code and there's a whole history of collaboration here but we should probably talk about doing something together but I mean I think it's interesting also that this is free software focused because again the kind of calendar this type that exists in Edinburgh there's a lot of events that kind of every day of the month you can go to something but there's really nothing none of them that are actually focused on the issues of freedom and so on so this includes everything free software and the guidelines are pretty strict but at the same time if you're talking about the subject that covers 90% social issues and there's 10% free software related it'll get in yeah but I mean a lot of a lot of big meetings of this type that happen even if it happens to be about a free programming language or so on people are just not interested in these issues so the fact of even if it's that the group has some recognised interest in that area it's different from having zero interest so I'll tell you what it took to to get the calendar as full as you see it for the past week even though most of it is depth-conf this week as a president and as a member of the organization behind this and a bunch of people maybe 10 or 10 to 15 we had to attend every single free software event that showed up anywhere in the radar 4, 5, 6 times over a year or two let them know about this and almost beg them to put their events in it was very very very hard and I think it's also apart from people being able to see future events the fact that if you can for any individual group being able to see the history of events also makes again if you're a potential new person you have a feeling that this is an active group it's kind of more comforting to join it rather than that you think you'll turn up and it won't really happen and then it helped a lot that we were able to burst out of our comfort zone and bubble and I'm not a Fedora user so let's see these people, let's meet them and let's go to their place and invite them over really worked out well I think one other thing is communication I mean just communicating that meetups exist for Davion that is I think also key like for example the open street map community they have a regular newsletter that kind of summarises what happens in the community like it's called weekly OSM and they always they also have a calendar that passes on the community page with all events and that just creates a lot of discoverability you see like oh there is a there are people meeting in Montreal there are people meeting in Stockholm wherever and I think that is also key to motivate others to well why I should maybe start one as well so this is something maybe if we create such a solution to connect with a publicity team to put that in bits or something like that so I mean quickly does anyone have anything they want to say about imagine that we were making a new site that maybe takes information from the wiki or whatever it does but was making this more visible does anyone have any opinion that they want to mention on what should be listed there or what should be allowed to be listed I mean how do we define what is a Davion group or do we just say what they are going to have and replace going on with Davion for example I would be comfortable with any group where people will be made to feel welcome where they can ask questions about Davion where they can get help to install Davion so whether it is a Davion group whether there is a Davion developer or not if people have a question about Davion and they can go to that meeting and hopefully get a positive reply then I think that would be a group that we should list this all points to the welcome team I think because we already have we have a couple of people and I am one of the contacts and we are trying to improve the newcomer experience and to me someone new does not necessarily mean someone new to free software it is also someone new to the developer community so you may be a developer elsewhere but now you want to come here and you are curious or someone that has no technical background whatsoever and then the first contact should be actionable and really quick response that is what happens in Ubuntu you want to join the community you create your account, you log in you are translating in like 5 minutes you are wiki editing in like another 5 minutes and you find your parties and people and everything in like the next 10 minutes finding the people I think is the key place that is missing if you know how to do wiki editing and how to report bugs I am fairly comfortable you are going to find your way around in Davion but if you want to find the people it is another story some teams are already clearly identified with contacts and everything some others are not there were a few talks about teams communicating with each other being difficult at some point so I think that is one of the parts so if anyone wants to start a group that person should find within 5 minutes of getting to Davion their work how to do just that even if they know nothing else about Davion I don't know I was listening over streaming about some of the people that had meetings elsewhere someone mentioned Catalonia was you maybe you can share with us how did you find out about the local meetings or other people there for Davion how did it start maybe the local group in Catalonia started because of the Davion user catalan list yes the mailing list so from there some people some of us we know each other and we decided to meet physically and from here we started to meet more regularly but lately sadly we are not doing so much well the last the last day we do a release party but it was not a party it was a hiking I agree with you and you don't have sometimes it's more to to get in touch with people more than to do a very techy talks for instance because we can do it virtually but the history of catalan group was this that we wanted to we were talking about things in the list and then become the local group in fact we registered as a local group not long time ago but we were the group before we registered it because we were doing things and some talks things like that but not with a very regular basis so I mean for making groups more visible one thing maybe has been mentioned is to try to have ongoing meetings that could be only I mean in some places even if it's only you say you have a some meeting every summer or something at least the fact that there's something on the web page to say that it's still alive I think is reassuring to people who it gives them a reason to contact to bother contracting the group if they find out about it I mean I don't know what else people think would be good again one thing I haven't put on this side I think I mentioned somewhere else is probably nowadays the same kind of information as well as mailing lists and so on we probably ought to be trying to feed this information out to the various types of social media that people find things on nowadays as well if you want the deviant Catalan user group we have a we keep a gently but I don't know if it's the best if you want you want to show it I don't know if it's the best example hi I'm Kathy Sutter in observing the community over about a decade from a distance and not making big efforts to be involved I often think it might be helpful maybe in future conversations to talk about what would be lost if all the groups became more open and that's a good way of discovering why they're not opening so there's an interesting social trust that's built up and it gets disrupted when you have events where you need to be nice to a lot of people and the building up of those close relationships can be very crucial and I'm not saying that that deviant shouldn't open up I'm just saying it's a workload I think one issue on that maybe as well is how you if we were trying to start and say how should we actually market these things or brand them then there is a fundamental question which at the moment we haven't really dealt with because in most places we haven't been trying to push these groups very much anyway but are these who are they targeted at for a lot of what we've been discussing here we've kind of been thinking about targeting at people who want to be deviant contributors in some way and maybe that is the right thing to do a different possibility which some groups have pushed much more in different parts of the world is just to be about encouraging deviant and trying to have more public facing events with well again in Catalonia there have been events with different days of talks and so on again both things can work but again they are slightly different so from outside I see that there's a doocracy instituted to the extent that a person has to show that they will contribute and are contributing before someone will take the time and energy to make more personal connection with them and so I think that's not a bad thing it just has this trade off of being difficult for new people I can see to some degree that for me the kind of contributor focus has some validity in the sense that in most parts of the world there already are for example Linux users groups so again there's not much point trying to duplicate that exactly and I'm not saying it's bad if people who are just a user turn up to a meeting but it's still not clear to me that trying to create a new set of Linux user groups purely focused on Debian would help anyone maybe maybe I don't know that's something we were confronted a lot here in Quebec because there was a very strong community of free software users all kinds of different users and maybe we can draw a parallel with programming community so there's all kind of groups here now gravitating so there's Python Montreal there's a group about Javascript there's a bunch of other web developers and focusing on different technologies and some user groups really focusing around the one specific tool and probably the only problem is when they have meetings at the same time and in some occasions we have done for example the club Linux at Amic meetings have been focusing on one distribution or the other and we show up and we do demos and so on and I don't think it's a huge problem most probably someone in marketing would tell you well there's the brand is not clear or you're not respecting this or this kind of rule for typical marketing but as I said before I think you need a group of one and if you start with that you'll discover it if you remain a group of one after three years well maybe there's no point in putting such effort if your group of one grows to 200 in a couple of months well maybe you do need a structure and a lead and resources and stuff so So one other question that you were implicitly raising before is what can Debian centrally effectively do to help any of these groups if they want to so clearly at the moment we are providing a minimal level of infrastructure in that people can put their entries in a wiki they can get mailing lists if they want to and so on I think one thing we're not really doing at the moment that has been mentioned is probably we should try somehow aggregate the event information and push it out again it's not it's not necessarily the case that that's going to be how you actually get the attendees because they might get it by searching directly for something in their city rather than by seeing in the central Debian news but some people will see it that way and it also just gives a feeling of life I think somehow Right but then there's discoverability if I'm in Montreal I'm very interested in knowing if there's people in New York that are broke Ottawa Boston New York Yeah why not a day trip to go see the other guys next door in Ubuntu I think one thing that helped a lot initially other than giving away free stuff was having clear branding guidelines so and I think that's done with Debian it's clear that we can use the logo for this or this or this and that verifying a bit more in a context of local groups would be nice and you'd be amazed how many people just print out stuff make t-shirts and give them away for free on your behalf without you asking them just making the logo available that's one thing I remember and the other thing was let's not put the weight on the publicity or marketing team to discover stuff and aggregate it but let's help them make available a way to send them the information easily and I call RSS or whatever text format I think we should have a way to extract our Debian events and if we start just with us too and we'll probably find that other people are doing the same thing and probably get a nice list by a couple of months and then they discover each other and I don't know and do people think that that it would be useful for Debian to spend money on these things somehow and if we did spend money what would it be for well I wish I would have known how to invite other people to Debian camp for example the week before is a huge it's an opportunity we could take more advantage of and if I'm going to Taiwan next year I'll probably get there a week earlier and set up a help desk and meet the users and so on and so forth so by the end of week of DEBCAMF 18 we know there's an organized group and if there isn't then there is probably no point but at least put the resources there in some time to do it while at DEBCAMF just on that question of money one thing I'd suggest this roll up banner next to More is I've got three of those just with the Debian logo on them they were actually produced for us by the FOSAsia team they produced a whole batch of them in Singapore and so I just take one along when I go somewhere and I put it up it wouldn't be hard to get a couple of those made for every developer so whenever someone shows up somewhere they just put it up even if it's not strictly a Debian event maybe they've got a table somewhere maybe it's a ham radio event I go to some of those as well so that's just one possibility on the question of social media this keeps coming up in different forums and there are some people who feel that you can't do anything without social media these days and there are other people who really push back on it for various reasons including the privacy the fact that it has non free javascript and what have you now I've been to many events this year where I've met new people who I've never met through Debian or free software and every time I go to an event I find out about at least two more events without using any social media and in several cases people have asked me to come and talk at their next event or another event that they know about so I don't think we need to be dependent on social media now some people might choose to use it and being a free organisation we can't stop people using their browser to browse to facebook.com I don't personally do that myself but yeah we need to look at all the alternatives there and really going out to events that are outside our comfort zone is quite significant I went to an event in Cotor recently which is the digital born media carnival there were only a very small number of IT or developer people there mostly it was journalists lawyers, policy makers researchers and academics so it was really interesting to have two way conversations with these people and find out just how they perceive what we do some of them were really clued in some of them you realise that the messages are not reaching them and we have to work harder to get the messages out there about free software mass surveillance and all these issues but you only get that by interaction with people the social media is one way and sometimes it's not even one way you put it out there and it never even reaches anyone at all so any other topics people think we should be mentioning just to your previous slide about node 1.4 so you were visibility about the wiki page so I think one big difference between the pages you showed is also you have the world map I think it would be really nice to have something like this on the wiki page so it's really friendly and you see oh there are many groups and then you scroll down because down on the wiki page you really find information about groups I looked it up before I think for me it's really nice if I want to get in contact with somebody I can find this but also maybe include some information for people who want to make a group like it's easy or even when you say about money or about roll-ups include this there show people who have already a group want to do more publicity that it's easy to get stuff also I've been to some tech meetings and I see what people like is also to have some free food and beer so I'm not saying that's also a way but also it's an engaging way for people to go and to attend and I know that not everybody but sometimes it's an encouraging thing to go so maybe I don't know who needs to sponsor that or whether it's a good idea to necessarily Devin to sponsor that but it's another way to encourage people to go and socialize Any other comments? So I think I need everyone in this room to follow me to the welcome team BOF right after this because the ideas I have are completely on another level and this seems more to the point of welcoming new people so yeah if you're with me follow me after this but yeah regarding the money I think it's it's a strange thing because when you don't have it you need it and when you have it you wish you didn't need it and it makes things more complicated in many levels but sponsorship I think it's a good way to make it simple if someone wants to organize this and they're willing to sponsor it or they need the money one thing that has worked a lot in Quebec here and that I made sure in organizations when I was involved in that capacity for example I would hear some people saying we're going to do an open street map party and mapping the neighborhood how can we get more people and they said well we wish we had money for this well did you ask around oh no not really so don't hesitate to ask your local free software or tech group or even the electronic shop around the corner sometimes with 50 euros dollars you can get a couple free pizzas and maybe get the more mappers or more I know here in Quebec there's a few places you can ask but if you haven't asked yourself that before today just think about all the people gravitating around your community that could throw in a few bucks maybe even family I don't know are there people here who are not currently going to a regular WM meeting say but would be willing to try and create one where they're living or maybe maybe so if you put your hand up then are there things that you think would help you do that or it's just about you getting around to it so I live with a developer we talk about Debian all the time we have local Debian developers in the Portland area in Seattle so basically if someone internationally is coming to Portland say something on IRC and then hopefully someone will propose that we all meet together and it might be a group of from 3 to 15 people will come and greet that person and say hey what's up since we last saw you and then there'll be technical conversations and that really is the extent that I see of Debian social in Portland I don't make an effort to help because I've found that I get thrown into the girl jobs which I don't enjoy and that is I see a bug squashing party and no one has arranged chairs or cleaned or made sure there was some food to eat or water and people start getting old cranky and uncomfortable and then I go oh and then I end up being the girl and so I just watch and I enjoy the conversations as I come up because I live in Brazil and I participate in groups and social movements that we never have money to do anything and things just happen and but I have been doing some workshops about Linux and in Stalfast with Debian so for me it would be really good if there is other people doing that in Brazil that they can meet and we can talk about that what's good, what's not good the space where we can use to do that so that's what I'm looking for so yeah good so unless someone wants to add something urgently I guess that's one hand up over here I'm from Delhi, India and I think the problem which I face is that I don't have a I don't know much people who are Debian developers in my area and even if I google Debian India and there is not a proper list of people who are there near me and I go to meetups and I meet people in open source but it is very hard to meet Debian developers in my area and the last conferences which I see in India are very around 2006 and so there is not a proper updated list of Debian developers in my area and even if there are five people around and we can just meet up and discuss about Debian projects, I think that is what I'm looking for so hopefully some of us can carry on discussing these issues and including apparently in this session in the other room we know where this other welcome discussion meeting is happening woody maybe somewhere else exactly but I think we should wrap up for now and hopefully we can carry on discussing thank you


Over the course of this academic year, I've been working with the fantastic teaching staff at Marlborough Boys' School in Central London. And part of the work that we've been doing over the years is unpicking some of the ideas in my research mark plan teach. And in this video, you're gonna see the teacher discuss what they did next as a result of the teacher training sessions. So we're unpicking here how they've translated the idea and adapted it to suit their own classroom context and their own subject specialism. And this is what great teaching requires all teachers to do to translate lots of ideas and apply it to suit their own wisdom. Take a look and see what they have to say. Hi Aldous, is that audio coming through? Yeah, we can hear you, great. Okay, great. Sorry, our camera is on, but I'm blaming Dubb's laptop here for a thing. But so yeah, my name's Locky. One thing I took from the in-person session we had with Ross was the feedback script from the teacher toolkit. I'm holding it here really engagingly in front of my camera. So, oh, so basically the script was the Pipple. You got it? No, it's not there. It is. Oh, it's different. Thank you. Okay, we can see you now. Hello. Sorry, this, I'm very tech savvy in Australia. So this is the Pipple script. So praise, probe, identify, plan and lock. And I gave it a crack. I kind of sat it under the telephone for a few tricky parent phone calls. The first few times I've planned it out using this and have a think beforehand. I noticed that basically myself and most teachers kind of do a lot of this already. One of the main changes I think to my practice from this has been the praise and just remembering to use that. So, yeah, just in a couple of really challenging phone calls I've noticed the positive impact of starting with a bit of praise, commending that students effort in class, their improvement in work practices, whatever it might be, and then getting into the, okay, but your son has been de-classed, whatever the reason for the phone call might be. But yeah, so as I've become more familiar with it, I found I don't look at this script anymore, but that praise and also the at the end locking in tangible actions that you can do are really now embedded into my practice. So I don't necessarily think about the Pipple structure anymore, but certainly those two aspects of it are things that I now automatically do. Fantastic. And can you do it in five minutes? Have you mastered that part yet? Easy money, Ross. Right, good. That is great, great news. And have you tried it in other situations, so with kids or with colleagues? Yeah, so when we have, as we're all familiar with here, de-classings when the students send out of the classroom for being disruptive or whatever. So we'll have restorative conversations afterwards. So I've also found it really handy for those restorative conversations as well as then the parent facing side of that, which is the phone call home. Okay, well, that's great news. I'm gonna sleep very well tonight, so thank you. Cheers, Ross. Right, excellent news. That's really good. So here we go into next.


OK, tonight's match was huge for us. After losing to Eastern 16-14 in the fifth last night to be able to rebound and play with as much intensity back to back, we didn't have much preparation time at all to get ready for Gettysburg. Shannon Bailey had an incredible night tonight. And her setter, Mackenzie Blevins, was just putting the ball right there. And she was unstoppable tonight. And I think that was one of the biggest differences in the fact that our passing really was pretty good tonight. And our serving game did a great job to get them out of system. Well, we're a young team. And we'll go down the tunnel a couple of times where we just don't pass well. And then we make errors. And the other team played great. They had a really good second game. And so that happens. And so then being able to rebound, which is kind of what happened last night, because we won the first and third last night. But the team that could play consistently well longer. And tonight that happened to be us. Gettysburg had their moments where they looked unbeatable. But then they settled down. And I felt like we played consistently well longer. Well, now we have a practice tomorrow. But we're actually going to take the weekend off. And then we'll have three practice before Alvernio on Wednesday, which is a conference match. And it's away. So that's a huge match for us to set the tone in the conference and start getting on a nice winning streak.


Weightlifting. Think of the sport and one might picture a weight room ringing with the sounds of clanging metal and crowded with experienced muscle bound men. It's no place for a beginner, a woman, and certainly not both. Women in Weightlifting, a UC Berkeley club is on a mission to change that. So my name is Tara Asachi. I'm the president and founder of Women in Weightlifting. I founded the club last year, 2021. There's like a few reasons why, but I guess the main one was just over the years of being in the weightlifting community myself. I've noticed a really large amount of people who are like intimidated by the gym, like women especially, because it's a male dominated sport. So the goal really was just to build a community and you know, bring in some professionals to educate people, get some trainers. I started weightlifting in my freshman sophomore year of high school. I was like a really skinny person. I like had a lot of negative things to be said about myself by like other people. So it definitely like internalized a bit and that's kind of why I started out weightlifting. I wanted to like build some muscle and become strong. And then I just grew like a love for the sport and like a love for the strength that you build. You know, I always for strong woman and empowerment. And so I felt very empowered every time I was in the gym lifting heavy weights. You know, I want other people to feel that way. Weightlifting is something I've always wanted to do, especially being part of just a group. Because I've always really like struggled with like my weight and like body image at a very, very young age. Christine instantly felt connected to all the women at the club's first training session as they seem to be united by one common goal. A desire to look and feel their best, something she has struggled with her whole life that has led to periods of self-harm. At a very young age, like five, I was like sexually abused. So I've never felt like my body was my own. I've always felt it kind of in a way repulsive, you know, because it was seen without that permission to be seen. I wouldn't eat. For days, I wouldn't eat at all. So I struggled with that for a very long time. And then there was also moments where another phase in my life where I did resort to cutting my own skin because it just didn't feel like my own. Now I feel like I love my body, but I need to work on it because I have neglected my body in a lot of ways. Christine appreciates the stability and instruction that has come with joining the club to especially valuable concepts in a field so fraught with empty promises. The fitness industry, especially through social media, is a little bit dangerous because, you know, everyone can be a fitness influencer. A lot of people just blindly watch them and then thought that's the right thing to do and that can definitely be dangerous.  I'd say definitely in the sense of community, we've built that for our members over the past year. But in terms of education, we hope this semester to really push that and get that going, yeah. If you're interested in weightlifting and you, you know, view the world through the lens of a woman or you understand the struggles that women face in sports like these, then, you know, we are open to you. We, like, welcome you with open arms and encourage you to step foot in that weight room. You have every right to be there as much as a man, I always say this, and yeah, you got it, you know, you got it. This has been Ava Andrews from CalTV News.

The University of Pikeville was recently recognized by the Kentucky Chamber of Commerce as a gold status workplace regarding their COVID-19 vaccination rate. Earlier we spoke with Dr. Burton Webb, President of the University of Pikeville via Zoom to find out more about what this recognition means for the University. The University of Pikeville is really pleased to announce that we have passed the 90% threshold for vaccination rate of all employees, so faculty, staff, and I believe our actual number is a little over 91% now. That puts us in the gold category for the Kentucky Chamber of Commerce's vaccination challenge, and so we thought that it was a good time to do an announcement for that. When asked what the primary motivation was that drove the University's successful vaccination efforts, Dr. Webb mentioned the school's desire to help keep the community safe. Well, I think it's keeping the rest of the community safe because if you have a high vaccination rate, you can't, you know, spread COVID very easily. And if we can keep the disease from getting a foothold on the campus, then we can return to normal operations. So I think our real reason is about keeping the rest of the U-Pike family safe. And the faculty and staff have done an outstanding job of reaching this threshold. While the University's efforts to encourage vaccination amongst its faculty and staff has seen this success, Webb mentions that the vaccination rates for students has been lower. However, he states the school is still working to encourage a similar increase in the vaccination rates of its students. Most people have been very receptive. There are some folks who don't want to get the vaccine, and we don't have a mandate on our campus. We do have, we've asked people to get vaccinated. And if they're not going to get vaccinated to be tested on a regular basis to make sure that they're not infected and spreading the disease, and that's gone very well. So we've had most folks choose vaccination over regular testing, which makes sense. But if some folks have a strongly held belief that they really don't want to be vaccinated, then we'll comply with the testing. It's been a really good and successful program. And right now, our students are still at a lower threshold than that. So we have some campaigns running with them to encourage them to get vaccinated because it's really our only way that we're going to be able to move back to a much more, what we would call normal, right? I think there is a new normal now post COVID, but to what we would call normal life. So getting vaccinated, making sure that the disease cannot spread on a campus where folks live in close proximity like the University of Piperville is the right decision. For those still considering whether or not to get their dose, Dr. Webb offers this advice. I think that, you know, if folks still have questions about vaccination and about whether it's the right thing to do or whether it works, you know, the university has actually posted a few videos online explaining what the vaccine is and how it works and why it's important to get. We've talked a little bit about why it's still important to get a vaccine even if you've had COVID because, you know, that helps to reduce the likelihood that you'll have a life-threatening infection with the virus. So I think I would encourage folks to examine the data to ignore what's taking place in the, you know, the war of words that happens between the left and the right and look at the data, look at the science and make a decision. That's the best thing to do. I think we're in good shape. You know, infection rate on campus is very, very low right now and has been for a couple of months. So life is good on the hill and we're moving forward. For Mountaintop News, I'm Joshua Slung.


one year, three months and two days, it will predict that from your previous data. So, you have to be alarmed that I have to buy another hard days, I have to add more hard days data, hard days into the system after one year because after one year, two months, three days, it will... But naturally, people think that this month 10 GB, next month 20 GB, third month it will be 30 GB. No, it depends on data. Maybe it's a holiday, it's never been used. Maybe it's like a COVID situation. People have predicted that their database will be full after three months. No, it's never been used because nobody came to the restaurant which is filling the data. So, this kind of aspect always taking care in the AI. AI predict that if you see that you are using one GB daily. So, normal human man think, oh, seven days, seven GB. No, if it is that Saturday, Sunday is holiday. No data generation is there, maybe one MB. So, it will taking care of that. It taking care of the holidays. He start learning that, oh, okay, first of July is holiday in US. Okay, there will be no data. So, it will predict, he will see that because in previous day, he has seen that on first slide, there will be no data. He has a 10 years of data and see the first slide, there is no data, no data, no data. That's mean on next slide, there will be no data. Model with trained with the previous data. Now it predicts that your hard disk is full after that. So, this is the database activity. And even malicious activity on your database. You see that this IP address usually come from that area. This IP address is coming from north of Europe or something like that, central Europe. Usually these IP address, so model is trained. And you see that this IP address is coming from the America. It's not possible, it's a malicious activity. Maybe they are spoofing that. They are changing the IP address, something like that. So, the model is trained. You are not manually inputting that IP address. This IP address is from Europe. You are not manually inputting that. It's extracting that feature from that. That this information is coming from the Europe. This IP address is coming from the Europe all the time. And this time it's coming from the US. Similar like, it's not IP addressing one, anything. You see that 99% chances are there you are Google, using the Google. You see that when you are using the Google and you have a Tor or something like that, which is hiding your IP address. Sometimes we say you are a bot. Because first you use your computer and search it and it's coming from the France. And then Germany said, it's not possible that you are switching the time that frequently. So usually it just put that you are a bot. Just click that you are not a bot. So the algorithm is running that this IP address are coming from there. This is there. The search, usually the search is coming from that area. So they just aggregate that. And resource exhaustion. Definitely I already told that the resource exhaustion that it can predict that when this resource will be exhaust. The memory, something like that, the hard days, the CPU. So, that's it. Do you have any question? Yeah, actually in AI concept, you're running the algorithm. Yeah, if you're running the algorithm, I usually you see that normally the AI algorithm, we are using the Python, right? Even you are using the C is a separate question, where I will go to this C question. Python, and in database you are using the PL Python. It's actually calling the Python library in that. But it will give you the SQL interface, easy interface. Other than that, if you don't want to use that, you can directly use database, directly use the database and write a C application for that, write a C application. And using that database information, definitely it's a bit slower than reading from the CSV file. Definitely when you are reading from the whole file, like if you are reading the whole table from a database, it's slower than when you are reading the whole CSV file. But if you are curing database, specific amount of data, like if you have a CVS file, which has one year of data, right? So, if you are writing a C code to run the machine learning algorithm, you have to run that to 1991. You have a 10 year, 1991 data. But then you have to read the full file. But in the database, you have the capability of indexing or something like that, which will give you the 1991 data quickly. So here the index, the other thing of database involves. But in a CSV file or something like that, you have to read the full file. The Curie performance? Yeah, it's definitely when you are training your model, training your model, it's not very efficient. Maybe if you are training your model on previous 100 years of data, maybe it will take one month. You just start running and after one month. But when your model is trained, when your model is trained, your algorithm is trained in that. Now you put that, it's really fast now. But training is definitely a slow process. Usually you don't that. Usually you don't that. You are not doing that. You are training and you are curing. What we usually do that, if usually the training is an offline process, like you trained your model continuously in the background on a Saturday, Sunday life, Wednesday, Sunday you are using that. But while you are doing some interactive work, don't train your model at that time. You use that model. Use that model, don't train that. Because training is, people usually do that training on GPUs, not on CPUs because it's a complex process. Yeah, absolutely, that's a really good point. And on the redeplica you can do the training and the actual one you can do the, that's a good point. Yes, absolutely you can do that. You have to wrap that, you have to wrap that into the SQL. Like if I write that create procedure or create function and then you write a Python code in that, actual Python code in that and at the end you're a language PL Python. And when you run that function or procedure, it will actually run your Python code in that. Yeah, I think it's automatically loaded. PL Python is automatically loaded, as far as I know. Yeah, it's a common PostgreSQL extension. Yes, it's a common, because it's not, because it's part of the core of PostgreSQL. It's a country, yeah, it's a country, actually it's a country core. Like some extension are, when you build PostgreSQL is a part of the PostgreSQL and PL Python is one of them, actually. And PL PUL is also one of them. Thanks everybody, yeah, sorry. I have not that experience that. You can use that, but I have not experienced that on that. Thank you. So, if you have, we are looking for you, join us. Yeah, the Parcona, yeah. Now keep it up. We are open, you can go there and you can find the many jobs we are looking for the people. Thanks everybody, yeah.
