Now, if you are still considering buying a driver in the remainder of 2023, then one of the key attributes that you should be putting on top of that list is forgiveness. Because as average golfers, it's certainly what we need and require, and the five drivers that I have in these boxes come with forgiveness as their number one priority and pretty much it's available in abundance in my opinion. Before we go any further, I want you to get involved in a comment section below, ac rïm ni i nhw y r.'ymystio'r ddoch yn oed o'r gwasanaeth mwy i'n ddweud o 5 o 5 o 1. Yn ystod y gallwch chi gynnwys ar gyfer 5 gydydd yr 2023, oedd yn cymryd y gallwch. Oe, rydyn ni'n rhan arlo, nes dy fath o'r pyl y ddweud o'u a'r rhan o'r bydd, It is from Callaway, it is the Big Bertha 23. Now it's a real interesting product this because Big Bertha is synonymous with user friendliness in my opinion in terms of golfers. But what they did with the Big Bertha 23 different than the other drivers that are out there right now including others in their line up is this is an extra large face that has been designed and that design has also meant that we've got a bigger sweet spot and therefore higher MOI and higher levels of forgiveness. It's the key attribute of this Big Bertha 23 line up. But the other key attribute is also offset and draw bias. It sits at number five because yes it's super forgiving but you could argue that it's a slightly odd shape and heavily draw bias a lot of offset and address which be slight negatives and maybe reduce the appeal to many. So super super forgiving but a few little quirks in there that might appeal to everybody. Number five Big Bertha 23. Right let's go into number four. If you got involved in that comment section and went for the top five my guess is that you will not guess what is in this box. In fact it's not in this box because it doesn't fit in one because one of the negatives towards this driver is that it's not a got an adjustable hosel. The driver is from Zexio and it's a brand that I tried for the first time this year. This is the latest model. It's a Zexio 12. It is super forgiving. In fact all of the drives all of the products that I've tried from Zexio seems to have that as a real priority once again in their setup. What I'm unsure about with the Zexio product is they all seem to come with super lightweight shafts that are also counter balanced. That counter balancing is all to do with without going into too much detail squaring up their head at address from the top of our downswing. Tall story I know but what I can't argue with it was super impressive out on the fairways and that forgiveness if that was the key meant that my ball speeds remain constant and to be quite honest with you no matter what swing they seem to put on it the ball went relatively straight but also didn't lose any distance at all. Super easy to use, high launching ticks every box for me. The negative would be and why it sits in at number four is that non-adjustable hoswll for me is a potential downside. Right let's stick that to one side and we'll jump straight in to number three. Now number three quite possibly will be a brand that you have in your list but I'm not sure this would be the model but it's certainly the one with the most forgiveness with the from rather tailor made and their current stealth two line up. Now this is their HD model and that's why I said I'm not too sure whether or not this is one you would actually have chosen but trust me and what tailor made say is this is the most forgiving driver within their current line up and I would totally concur with that and largely for me because of the distribution of weight. I've not really seen a weight placed as far back as heavier weight rather placed us so far back it's 30 grams of weight they've shoved at the back end they've also put some weight in into the heel because this is obviously again another draw by a striver. The difference with this driver is though that the crown is normal in its shape it's very much the same as the others are slight tweaks but if you put all three stealth models down you'd be hard pushed to pitch which one is which so it's very normal if you like unlike the big birther which is a triangular shape whilst it's got offset it's not hugely visible and I wouldn't notice it or recognise it as a draw bias driver but the one thing that is unquestable is that 30 gram weight has been shifted way back and there's a huge effort in doing one thing and that's making this driver extremely forgiving and that's exactly what it is. Now we're getting down to very much the the nitty gritty and if I'm honest with you the top three are very much inseparable and minor detail as to why I would have chosen one over the other but we're into number two and number two will once again have probably featured on your list uh oddly enough it's from a brand that we have already featured and that is from Callaway but this time it is from their paradigm line up. Paradigm has been hugely successful for Callaway and not all of it has been designed purely based on forgiveness this paradigm X certainly has. Their goal has been to produce the highest MOI driver within their line up they've certainly achieved that once again you'll see about weight distribution is all at the back end and it is just all out a driver that when I tried it on the fairways no matter what swing I felt I put on it the ball seemed to finish in a similar position in terms of distance travelled. The one thing I'm slightly negative about with the paradigm line up in terms of the drivers and fairways and such is that it's a quite a very soft and muted sound so much though that you don't really recognize the difference between a good and bad shot and that's the bit that sort of surprised me is every time I hit a ball it seemed okay and you watch it travelling in the air it seemed to continue travelling and like I said from a forgiveness perspective I can even see from the close-ups here where I've hit I've hit all over the club face that is one forgiving driver and certainly deserves its place right up at the top end of the tree in terms of my top five that is the Callaway paradigm X. Today's video is brought to you in partnership with Hotgolf the online golf mega store bringing you the hottest deals in golf and of course the clubs featured in today's video find the link to the Hotgolf website in the description below and check out some incredible giveaways and offers. Leave just one box and once again I would suggest that this driver will have featured with in the list that you have put together it is without doubt the most forgiving driver in fact from the brand it's quoted as being the driver that has their highest ever MOI and when you consider who the brand is that's a bold statement because their whole sort of setup is very much aimed with being has forgiveness as being very much top of their priority list they make products for the the man in the street in my opinion and the Ping G430 max is the epitome of that. It's a super forgiving driver and its predecessors were also super forgiving but this is the driver that has produced the highest MOI ever from Ping. What I like about this and why it gets to the top of the pile in terms of forgiveness is because it as a club overall ticks other boxes in the fact that it's got an adjustable hosel that some others didn't it's also got an adjustable weight bar which others didn't so that gives a lot more customized options in what is already a very forgiving driver so without doubt Ping do this so so well they really need to drop the turbulence to get my full seal of approval but it's a super super driver it's super forgiving and for anybody out there who has tried this I think the one thing you might be bits that you'd like or dislike subjective opinions like mine in terms of turbulence but one thing we can't argue with is the Ping G430 max is a super forgiving driver and like I said at the beginning if you're an average golfer if you want to buy a new driver then forgiveness should be top of the tree in terms of what you're looking for in terms of performance you've got five drivers there which arguably could all mix them around and like I said from subjective opinions change them slightly but as golfers right now we have huge options and you must make sure you make the most of those options and get out there and try everything you can all of these drivers probably Bar the Zexio is readily available from most retailers and custom fit outlets so make sure when you get the opportunity don't go in there with preconceptions and buy yourself a Ping G430 max make sure you try as many as you possibly can and I'm sure you'll come out with a driver that forgives all those well slightly awkward swings that we put on every now and again and we need as much forgiveness as we can get right that's my top five drivers of 2023 thank you for watching I'll see you all soon


Okay, one, two, three Okay, hello folks, let's start our today's talk is about Sahara Sahara is a project that brings Hadoop to OpenStack today's presenters Myself Sergey Lukyanov. I'm the principal of the engineering varieties and project technical lead of data processing program Includes product Sahara in OpenStack. The next speaker is Metaforella from Red Hat and Jones from Horton Rocks So our agenda is a brief overview of Sahara project highlights from my Scouse release overview of HDP plugin and brief overview of Juno plans Okay, so the mission of the data processing program is to make some scalable elastic provisioning of data processing tools and a number of operations on top of them so in Sahara for a foreseeable future we were supporting Hadoop on top of OpenStack and two levels of operations for Hadoop provisioning and operate Hadoop clusters and then on top of this provisioning clusters provisioning scheduling and operations for Hadoop jobs So in the future we will grow to support other data processing tools not only Hadoop But for now as I say we're working with Hadoop and Hadoop system a bit About the Hadoop. It's not just a single project. It's something like the OpenStack it based on the two core Services named HDFS, Hadoop distributed file system and Yarn And there are tons of different services and tools on top of two core Hadoop projects There are some projects for streaming processing for DSLs throwing my previous jobs and etc So let's take a look On the question why you think that it's a good idea to bring To bring Hadoop to OpenStack So as you can see there are three lines the blue line is OpenStack growth The red one is about Apache Hadoop and the yellow one is the Amazon Elastic Compute Cloud Elastic Amazon Cloud Contains a product named EMR that's something like our concept of Elastic data processing in Sahara and As you can see Apache Hadoop was started much earlier than OpenStack But both products have the same Anger of growth And that's why we think that it's very good idea to Merge our communities and to bring Hadoop to OpenStack So let's talk a bit about use cases the first main central use case of the Sahara is to self-service provision elastic clusters This elasticity provides and user's ability to Do not keep thousands nodes Hadoop clusters on hardware and Just add remove nodes on demand so this this Use case Creates a new use case like Jeff staging in production life cycle Use case when you can just create clusters of the same configuration same topology, but different size or different Compute power for development Q&A And production using the same tool same cloud to a different reasons of one cloud and etc and one more Central uses to use case is running Hadoop workloads on top of the created clusters You can run workloads on top of the existing clusters or changing clusters to So let's let's take a look on the architecture We have a horizon plug-in that provides users an ability to control and operate Sahara service using the OpenStack dashboard is currently implemented as a plug-in for dashboard And we are going to merge it into the horizon during the geno cycle we're using keystone for authentication and we're using currently heat for resources provisioning and That's how we're provisioning resources for OpenStack cluster like instances volumes networks and etc Additionally a very big functionality of Sahara is implemented file system for Hadoop that supports Excessing data in SWIFT directly without any proxies or something like this. That means that you can specify Specify some data sources in SWIFT and use them from the Hadoop cluster provisioned by Sahara Let's take some notes about current status of Sahara in OpenStack. We were officially integrated OpenStack project And we just released our first aligned release named Ice House in time with all of the OpenStack projects Matt will make some highlights for it We have a bunch of supported Hadoop distros. The first one is a Vanilla Apache Hadoop. It's just a simple installation of Vanilla Hadoop with some tooling on top of it It's made mostly for as for the reference The second distra is a hot-on-work data platform And then we have into distribution of Hadoop too. It's currently closed and in the process of merging into the Closed distribution that is now in the blueprint Additionally, we have we have a review implementation of Spark. It is not a Hadoop and it's Really the first non-Hadoop data processing tool in Sahara, I think Additionally, I'm glad to say that Sahara is included on different OpenStack distros in Red Hat OpenStack and into the Miranis OpenStack too Additionally, I'm glad to say that we have a big community right now And I'm really glad to see new names in this list so Let's Move to the next speaker. Hi, so I'm Matt I'm gonna talk to you more specifics about what's actually happening in the the ice house release of Sahara So if you're not aware, this is actually the fourth release of the project code the first release Where it was called Sahara and the first release where it was incubating with with OpenStack so through the four releases we've seen a nice growth of participation and whatnot in this previous in this exact in this release we actually had 142 bugs which I think was it was pretty high nice growth for us. We saw a tremendous amount of Blueprints and new features that were added to the code I'll go through some of those and then I'll hit off some of the the big ones around to the the workflow management CLI and then John will talk about HTTP enhancements and through that we actually saw about 32 people who managed to Contribute and make their way up to the the launchpad Metrics for this if you actually go look at the commit stream was coming through there another dozen people or so that were involved in the project And all of that we did it all using basically the standard process You can't quite see this here, but we're releasing at the same time was the first release where we weren't actually doing all the releases ourselves You're just keep going through the the same system that's all the other OpenStack projects do and I Mention all these things and this is actually just a part of what we've been working on if you go and you look at The client library or you go and you look at the disc image builder Elements or you go and you look at the puppet modules you go and look at the dashboard You see even more contributions and whatnot so with that Some of the big features that I want to point out to you for the ice house release The first one is our tempest integration So everybody who's kind of who's even remotely familiar with OpenStack knows that OpenStack is really good for maintaining code stability API stability code quality Sahara itself has had a large amount of Unit tests and integration tests that have existed through its four releases This release we've started pushing things up into tempest which will help us maintain even better API stability and Integrate even more with the OpenStack infrastructure So that's good for anybody who wants to use it Plus anybody who wants to develop on it the second thing that's going to help people who want to develop on it as well Is that there's more integration in Dev stack? So this helps people who want to do the developments But it also helps the project itself as we want to get into the more of the OpenStack gates And whatnot and maintain compatibility there So the third thing I want to point out here is that in the ice house release We actually did the first release where we pushed all Hadoop 2 Plugins into the system if you're not familiar with Hadoop There was an architectural shift between Hadoop 1 and Hadoop 2 or Hadoop 1 There's a pretty much just HDFS and map reduce and then an ecosystem of projects that interact or integrated with one of those and Hadoop 2 it's actually there's a platform that's provided with the yarn layer which is a resource manager and Map reduce is just one of the frameworks this will work out pretty well for us as we go forward as a data processing program within OpenStack and Also having this availability means that everybody is actually using a Hadoop distribution these days They're going to be using if it's a Hortonworks if it's cloud error if it's map bar or whatever They're going to be using Hadoop 2 and they need to have that functionality when they come to OpenStack So just a few other kind of scattershot features that are coming in we actually released support for HBase We've got we're building now images for running in your cluster that are using Spark We've done a lot of work to move our kind of native Original provisioning engine to use heat the hope is that in and I guess Sergey will talk about this But hoping will be just switching over to that for Juno There's also pushed to add Internationalization we did for folks who don't want to run all their services as root we added some root wrap stuff in and then part of the heat work and part of our kind of like changing our architecture to be more Agent-based we actually have a start of an implementation of a guest agents So those are kind of high-level features. I want to talk about Two kind of big areas. So one of the big areas for Sahara is elastic data processing or what we call EDP Basically, this is our take on how you do workflow Management and the goal being to make sure that people can actually come to OpenStack system They can not have to care about the details of the cluster that they're going to run their work on They just have their data and they've got some sort of question They want to answer and we move them through the system as as smoothly as possible got a quote up here from Amazon EMR about how they're they're actually running millions of these EMR Clusters these workflows on top of EC2. So having this functionality in OpenStack actually brings a workload to OpenStack Which will allow for kind of higher adoption and whatnot or at least we hope that is the case so In this in the Icehouse release updates for EDP. We actually have support through the The the Hortonworks HDP plugin previously It was primarily through kind of a generic vanilla reference implementation plugin So this is great. This means that you can set up your HDP cluster and then you can do all of your workload workflow through its using Sahara itself More more features that we added there We started out originally with being able to ingest data from SWIFT do the processing then output it back to SWIFT We've now added the ability to use HDF HDFS itself as an input output Which means if you have long-running clusters you can continually run workload across them or even if you have remote clusters You can ingest from a remote cluster due processing and then maybe output to a to another remote cluster I've added some new Actions so new types of workload that you can actually run previously was mostly it was pig hive map reduce added support for map reduce streaming and Maybe most interesting for like the total hackers in the group the Java actions which basically lets you run any Program as long as it's Java Doesn't have to be a specific Workload so there's that and then in the kind of like long long term We want EDP to be really smooth and easy to use framework We've added the ability to Relaunch jobs with new inputs new parameters so that you don't have to go through the whole process of creating up a template of jobs and what nots Okay, so that's that's EDP want to talk to you briefly about The command line interface which we've added so goal here is basically to have parity between what you could do with the Horizon dashboard it's what you can do with the command line For a lot of people my lease myself I tend to gravitate more towards CLI's which are more which are easier to script and whatnot We'll actually in the long term help us be able to do end-to-end testing of the system as well So in this you can do everything that you could actually do with the with the dashboard In sometimes not as smooth the fashion, but we're we're working on that the when I say not as smooth the fashion The the dashboard UI actually will allow you to do kind of like wizard screens to build up different structures And then like create a cluster and then launch it and whatnot With the CLI we kind of do that minimally we allow important export of JSON formats So you can you can build something with the dashboard then you could export it to JSON Tweak it a little bit with said here and there and then import it again if you wanted But we cover image management so this is Sahara's way of Associating images in the glance registry with plugins that Sahara runs to limit the amount of Times that people are going to try to run a cluster with an image. That's not compatible with We have all the functionality for node groups and cluster groups And job templates. I mentioned this has more of the the JSON input output, but it's still very functional We're starting to actually use it in a number of our in our tests Handling data sources If you want to come kind of find us afterwards I can show you what the typical workflows Or like or if we have time at the end they've got a nice little Slide to the describes the workflow, but data sources and job binaries data sources are things like this Swift's container or that's HDFS directory and job binaries are things like this jar file That has this main method and this other jar file that has another method that kind of stuff So but that can all be built up through the CLI as well Everything I mentioned before is all set up for these these last two Commands being able to actually create clusters and jobs and real long real run them launch them We adding some more functionality being able to scale and whatnot Coming up That's it at this point. I want to hand over to John to talk about HDP Thanks, man. Hi, my name is John from Hortonworks Hortonworks provides a plug-in to Sahara Sahara projects are very important to Hortonworks The HDP plug-in has been part of Sahara from from the beginning of the project Right now the HDP plug-in provides support for all of the Sahara functionality. We've talked about Nova Neutron scaling up Swift integration center support data locality and EDP one of the differentiators for the HDP plug-in is that it utilizes Apache and Bari Apache and Bari is the management framework that's used in the HDP stack So the way the HDP plug-in works is everything goes through the Apache and Bari It goes through the rest call it actually goes from provisioning Apache and Bari for you within your VMs based on your topology layout and then it proceeds then use Apache and Bari to actually lay out the cluster start to cluster for you So more important for the end user is that after your cluster has been started up You have Apache and Bari available to you for monitoring and managing of your cluster After you've gone ahead and provisioned it so you can go ahead and you could set up your security with that You can you can do monitoring via ganglia You can you could add additional nodes if need be in services, etc So, you know, you're not just stuck with a cluster that's hard to manage a monitor You have a nice Ui so there's a couple screenshots to the right there that show some of the you know the graphs that are available to you So that's something we've been working very hard on is providing good management and monitoring support And that's available to you here through the plug-in So we're also gonna talk about Why is this important to us so? Sahara provides the ability to combine the HTTP stack all the functionality available in the HTTP stack and an easy to use reusable deployment tool Sahara with an open-stack framework We also provide several pre-installed images So we have several HTTP images that you can use for our 1 3 and 2 0 6 stacks And they're available on s3. You could also use a generic image You'll get a little slower startup time But that way you don't have to have the the image be populated with HTTP bits All right, so talking about the HTTP stacks So we started with one so we sport several stacks we sport 1 3 2 2 0 6 and 2 1 1 3 2 is the the older Map reduce name the map reduce HDFS type of functionality Then we moved up in the 2 0 6 where we provided yarn and 2 1 is going to introduce further Storm and Falcon and going on we'll have solar cascading potentially in the near future. So the neat thing with this combination of Sahara and The HTTP plug-in is that as you download the latest version of Sahara You're going to get the latest plug-in which is going to give you the support for the latest HTTP stack you won't have to do any additional work. So as we add new services Part to the HTTP stack they'll become available to users of Sahara through the plug-in All right, so talking a little bit about disk images So there's a there's a project called the disk image builder that's available. It's a separate project But it it's used by all of the the plug-ins for Sahara to build VM images it's a consistent API across all the the providers to provide you a mechanism to build VM images HD plug-in is supports a plane a 1 3 2 with 2 0 6 and soon to be 2 1 preloaded images. So those preloaded images have HTTP bits already installed on them in the form of a local repository And that improves the startup time of your cluster Like I said, we also support a plane image where it goes over the wire and then I'll pull those things down if you Choose to start out with it say a plane centos image So the scripts also can be customized so in addition to taking running the script and getting all the the default VM image for say our 2 0 6 stack you can augment that the script to include changes for security Maybe some custom packages you want to add to your VM images. Maybe some tweaks some kernel settings and your OS, etc All right, so I'll talk a little bit about blueprints. So this is a little forward-looking Blueprints is a mechanism that we use within now within Apache and Bari to completely Describe a cluster in a text JSON format So this opens up some very interesting use cases between the physical and the virtual world. So What is a blueprint? First of all, it's just a it's a complete description of a running cluster So you'll be able to have a running cluster in a physical world. It's a physical cluster You've deployed this thing by hand probably taken you quite a long time to get everything, right? You'll be able to then ask in Bari for a blueprint for this running cluster It'll give you a JSON file that fully describes your your running cluster at that point you'll be able to take this blueprint and import it into the HTTP plugin and Ask it to spin up the same cluster with the same configurations and the same topology you'll be able to then override any topology specific or Yeah, any any configurations that you feel that you need to override in your virtualized environment You'll be given a chance to override those and provisioning your cluster and What what this allows you to do is? You know mimic something you you took a lot of time provisioning in your physical world And then just tell Sahara to deploy this thing and now you have a replica if you will of this cluster in your virtualized world More importantly, it's repeatable. So now once you have this blueprint You can then go ahead and provision as many of these clusters as you want based on this blueprint So some of the things that you know We're looking at internally to use as for is maybe something a use case where support might use something like this so we'll get a Support ticket filed from one of our customers and we'll go ahead and ask them, you know, send us your blueprint we'll go ahead and provision a cluster using this blueprint, you know through in our private cluster here and We'll be able to then take a look at what the customer's problem based on his exact configurations and topology So this is something that's now I think it's going to be released and I'm patching and barry and a month now and then soon to be followed in Sahara in the HDP plug-in right now We don't have the exact syntax of the blueprint support in Sahara in the HDP blueprint. I mean HDP plug-in what we do have is we have something is very similar So you could almost do this right now With with the HDP plug-in where we have something very similar to a blueprint that it's Jason basin was derived from the original blueprint Specification the we make use of the feature within Sahara that allows plug-in providers to have provider specific templates What we do with that is from you you upload this provider specific template and then it goes ahead and creates your No group templates and your cluster templates so if you don't wish to create these templates in the native manner through the Horizon tooling you can instead upload the HDP specific Template and we'll go ahead and create the cluster and the no group templates for you so like I said, it provides an interesting use case between the physical and the The virtualized worlds there where you can repeatedly deploy a cluster based on a standard Jason template And that's all I have right now for the HDP plug-in. So Okay, and The last slightly two slides. I think is about Juno plans. We have a brief general roadmap for Juno to Integrate with open-stike ecosystem better. We have in a plan to integrate a viscometer and ironic We slanted to publish some of our metrics statistics about Clusters about I do port clothes and etc. And ironic will make us able to provision Bermatt Island hybrid clusters that is a very interesting use case too Additionally, we are working on distributing a Sahara to make a giant in multiple processes like other open-stake projects we're working on guest agents to To remove for direct access from the Sahara controllers to the head of cluster notes Oh, of course, will you have some bunch of HDP and changements like new data sources new job types? And as I say in the first slides over working on merging dashboard to the horizon In fact, our roadmap will be discussed as a design summit that will be in the end of week Tuesday afternoon and Friday morning. Additionally, we'll have two more talks about the Sahara Talk about technical deep dive to the DB functionality tomorrow and the performance of Hadoop OpenStack and Wednesday So that's all Thank you and the questions Yeah Probably you should take a mic Can you elaborate a bit how this blueprint's concept is related to heat and in general, what are your plans on leveraging heat? Sure, so they're actually they're they're independent So heat is a way that we actually go ahead and provision do our back-end provisioning of the VMs Blueprints is more of what is the topology of your cluster? So you when you think of provisioning your clusters in multiple phases the first is you provisioning the hardware the VMs themselves Making sure they're set up. That's all done in heat. That's a layer below blueprints So blueprints comes in on top of that where you you have all your VMs set up your your networks all set up And now you want to go ahead and lay down your Hadoop cluster That's where blueprints comes into play So that it's basically the second phase could be defined by the blueprint Which is basically an HTTP specific template cluster template. So, you know, it's it regardless whether using a blueprint whether regardless of which Particular plug-in you're using it's always going to use heat and let's just specify not to on the back end to provision your VMs At that point each VM each plug-in then provision slightly differently One of the ways that you can provision through the HDB plug-in is is through a blueprint template Does it does that answer your question? Okay, I have a question on one of the slides I think it was HTTP 2.1, which is coming up. You mentioned Storm Yes, talk a little bit more about storm and what your plans are with that Other than so storm, you know is an app that we use within the the yarn framework of to HTTP 2.0 in this case 2.1. So it's It's a streaming API for doing real-time processing So that you know, that's going to be made available to users of the HTTP plug-in through the one of our 2.1 HTTP stack So I don't know the right agenda talked about the low-level details what actually storm is For this talk, I think it suffice to say that we make the 2.1 stack available to you and it's part of that stack The storm is is available as a service and based on you can deploy the service in its various components to the to your cluster via Sahara that will be available via a blueprint or Through the standard cluster templates and from the Sahara point of view will support storm topologies as a part of EDP I Got a little confused when you describe the plugins and the main projects Sahara Can you specify a bit more, you know, just briefly, you know, why are the new improvements that you plan to to add to Juno from Ice House and What are the reasons you are adding these new? new additions to the project Like what are your plans for Juno? Basically, what are you additions the new the new things you want to add there? Do you mean Edition of new plugins. Yeah in the project like our plugins or improvements to the project that you're you envision from ice house to Juno moving on It's improvements. It'll be ruined in all areas. We have plans on the new plugins. We have plans on in chains in our EDP stuff with a new job types data sources Probably updates for existing plugins with new versions for example for HDP plugins to dot-one version with new services Is the instantiation of an HTTP cluster intended to be within the guess of a KVM Hypervisor or is it Intending to leverage I want to do bare metal deployments of the HTTP instances themselves Everything is deployed to use in the novel instances. So it depends on how we are novel services configured For example, when we have the erotic integration, or it will be integrated inside the novel We'll be able to provision bare metal and hybrid clusters Currently we're a provision on the virtual clusters Is is there a capability to do them both at the same time? Into the same environment have a pod of Ironic deployed in a pod of virtualized Was that It's important here. We primarily we primarily use the nova interface So as soon as the nova interface provides us with that capability, we can we can do it We're not trying to circumvent or do something extra Well, actually one of the things I'm trying to figure out for our environment is how we can build customized Definitions of the blueprints so that we can direct that interface to say this segment needs to be on ironic this segment needs Yeah, we're playing that actually in the descriptor for the json or do we have to extend it to make it do that? Jason Right now is specific it doesn't have any notion of virtualization It's just basically topology and then you have to then map that on to another layer, which is What what are your VMs look like what your flavors? So there's gonna be have to be work to be done, but that's certainly a use case that we're looking at Do you have any plans related to a pot seeds park? Do you have any plans related to a pot seeds park? Yeah, so I mentioned I mentioned that we already have Disc image builder elements to create images that have spark. There's actually a spark plug-in That's under review right now. It was just updated again this morning. So there's there's good progress there So I think you mentioned about something that I wanted to ask so Are other than the HTTP parking do you do you have another example of parking? That you can elaborate a little bit more so that to help me understand the layer difference between the Sahara API and and the underlying So you're asking the relationship between The HTTP plug-in and Sahara proper is that right and I like to know if there are any other Parking that you can you can explain a little bit Other than the HTTP one and any other what I'm sorry parking Any other parking a plug-in. So yeah, we support we have a generic plug-in. We support We haven't Intel we currently support but that's going to be Yeah, so Intel the Intel distribution kind of went away. So, you know that may or may not be around for a long period of time So right now it's it's basically HTTP generic and Intel not sure of the future of the Intel plug-in based on the recent news with Intel You know kind of leaning away from that distribution So your question with regards to the relationship between the plug-ins and the Sahara proper so there's a formal contract between the two Sahara is responsible for talking through heat provisioning all your VMs it understands cluster templates and It basically creates your your virtualized Cluster is a fully networked at that point the controls handed over to the plug-in through an SPI and it says here's here's a topology Here's the nodes. Here's here's your cluster topology. I'm your Hadoop cluster topology Here's the cluster topology your VMs, etc And then it's up to the the VM the plug-in provider then to map that cluster topology on to your your You're onto the appropriate VMs on to you. Does that make sense? Yeah, so there's very distinct steps between the plug-in and Sahara proper, you know the plug-in is just basically I have I Basically have a bunch of nodes that I want to deploy Hadoop onto that's that's what it does Okay Quick question Rewarding so I'm very Monitoring piece right is going to be replaced by a Cilometer or Cilometer is going to stay as like very high level. I Just trying to understand the you want to plan for Cilometer. So by the Cilometer. We have two directions of integration with Cilometer first of all we can post different statistics about number of created clusters The life lengths of clusters number of jobs per cluster Something like this some statistics about Sahara objects and the another one Direction is to read some statistics from inside the cluster and repost them to Cilometer, but only some very important statistics We will discuss it on the design summit So so so it's it's not a replacement, you know the Apache Mbari is very fine grain monitoring of your your cluster where Cilometers I've been more coarse-grained really You can really drill down into very low level details in Apache Bari touring inside the furniture link like Mbari will work As an addition to other tools, yes, they don't replace each other they Have one question. So how does a UI look for this entire thing? So say for example the HDP plug-in does it have its own UI or is this all integrated into horizon? So stuff like you know say job cues or I want to know how how the cluster is or Some of the graphs that you just showed so were they as part of horizon or did every plug-in have its own UI for now the whole as her API is available through the horizon and We're a posting links to Hadoop tools like Uzi like web the UI for HDFS Is the links in horizon so you can just click the link and open the Hadoop specific web Management tools for example in Uzi you can see how your job's running on cluster and etc So that's how a patch in Bari is exposed It's exposed as a link so you click on the cluster you just provisioned and there's a bunch of management links and patching Bari would be one specific to the HDP plug-in at that point You then it brings it to the the typical UI for a patching Bari now you're outside of horizon It's not a pain within horizon Thanks. Thank you very much


Well, when you meet people all over the place say I want to help and the answer is well, here's the box number Well, this person will call you but you don't handle it yourself, right because thank you.


In our very first story time video on this channel, I told you about the Gray Man, the first ghost story I ever heard as a child from my mother growing up.   Anyway, before we get started, remember to hit that subscribe button, give us a like, tell your friends, share it around and hit the bell to be notified for more videos. Welcome to us, Oteric Atlanta. My name is Bryce and today I'm gonna tell you about Levenia Fisher. The story as it was told to me. And look at the story from a different perspective. When I was a teenager, I was in Charleston and I overheard somebody talking about how they were trying to rebuild the courthouse and all these big burly construction worker men were quitting on the job. They were having a really hard time getting stuff done. Now, if you are from Charleston, South Carolina or another town that has a lot of historical significance to the founding of the United States, then you probably have a historical society. Places like Charleston, Savannah, New Orleans, all these old cities, for there to be any renovations done in the historical district, it has to go through a historical society. So obviously it's pretty difficult to do renovations to begin with. And now we've got this situation on our hand where the construction workers hired to do the renovations are quitting. Just dropping their tools, walking out, not coming back. And for the person that was telling this story, the most logical explanation for why these big burly men were walking out on the job was because they were seeing the ghost of Lavinia Fisher. Lavinia Fisher, we assume, was born in the late 1700s, possibly around 1790 to 1795. We don't have any records of her birth. We don't know who her parents were. We don't even know if she was technically born in Charleston, she could have emigrated from England or elsewhere, but it is assumed that she was born in Charleston. And if it wasn't for the situation around her death, she probably would have gone on to be one of the countless many faces throughout our world history that have just fallen through the cracks. We do know that Lavinia Fisher at some point married a man named John Fisher. Now, Lavinia and John Fisher ran a boarding house. It was called the Six Mile Wayfare House that was six miles outside of Charleston, South Carolina. For those who are up on their history, again, Charleston was a very big port, a lot of ships came in, and so a lot of men would come in and out of Charleston as traveling salesmen. They would roll their carriages up, go to market, sell their furs, sell whatever it is they were selling. It was a big cosmopolitan area of business. And so for Lavinia and John, they set up their bed and breakfast, their little inn, to greet these men as they were coming into the city, give them a place to rest up before the last bit of their journey into market the next day. Six Miles, for us, doesn't seem that long of a travel to get somewhere, but you have to remember this was in a time where there were no cars, they were on a horseback. So Six Miles was a bit of a journey into the city. And so the story I was told was that John and Lavinia would take in these salesmen and these men would never be seen again. Now, this little racket they had going on apparently went on for a pretty long time. Of course, again, these traveling salesmen, they were not local to Charleston. And back in those days, there was no GPS. There was no way of really tracking someone. You could disappear pretty easily. So for their loved ones back at home for someone to go missing, there's no telling what happened to them. So John and Lavinia Fisher, they took this as an opportunity. They would take these men in and they would feed them and give them room and board. Well, the Orleander flower is a flower that grows in Charleston, South Carolina. And it is notoriously a poisonous flower. Many a days, dogs, horses will get into these plants and get very sick and sometimes die. So what John and Lavinia would do is they would take the Orleander flower and they would crush it up and put it into tea. This would kill the men. They would take the bodies, bury the bodies in the backyard and then they would take all of their products and sell them themselves. And then as I was told, the gig was up when one day a hunter was out with his dogs in the area of their inn. And the dogs dug up these bones. Upon seeing the bones, the hunter realized that these were not animal bones. These were human bones. He turned them into the city of Charleston. He alerted the authorities and John and Lavinia Fisher were arrested. Now, once that they were arrested, they were found guilty and sentenced to hang. Now for John Fisher, this was a no-brainer. But then when it got to Lavinia Fisher, that was a little bit of a trickier situation. You see, laws in Charleston or in South Carolina at that time said that a woman who was married could not be executed. And for those of you who are not from America or maybe are American and don't really understand American law, again, as we talked about in our Thomas Paine video, the United States is a republic. So what this means is that each state acts as its own territory or for lack of a better metaphor, its own country. No, this does not mean that if I live in Georgia and I go to South Carolina, I have to have a passport, not at all. We're all still united under the same country. But for individual states, there are different laws that states will vote on. So for today in 2020, some states have the death penalty and some states don't. And usually that is voted upon by the people that live in the state. So each governor rules over each state and the federal government is only meant to be back up to the state government. And of course, as I said in the Thomas Paine video, we do elect officials to go to Washington for the federal level to represent each state as well. So for South Carolina, this wasn't the United States. This was purely for South Carolina. The law stated that a married woman could not be executed. I apologize for all the sirens you hear outside. I think I've said in videos before, I do live in the middle of Atlanta and we are in a pandemic right now. So I hope that you excuse all the sirens going on. And I hope whoever is in those sirens are involved in an accident or sickness gets better soon. So Lavinia Fisher banked on this idea that she was not gonna be executed. She knew her husband would be executed, but she thought for sure she would be saved from the gallows. Well, when the judge said that she too would hang for her crimes, she stood up in court, yelled at the judge that he can't do that. It's against the law, she's a married woman. Well, the judge found the loophole. He looked at Lavinia Fisher and told her that he was very well aware of the law, but he believed that she deserved to die as well. And so he found that if he executed her husband first, then she would be a widow and technically would be eligible for the death penalty. So John and Lavinia Fisher were sentenced to die on my birthday actually, February 4th of 1820. Obviously it was not around in 1820, but that is my birthday. And on February 18th, they came to collect both John and Lavinia Fisher. John went first and he stepped up and at this point executions were public events. People came to watch this person die. For the life of me, can't understand how watching someone die would be entertainment, but to each his own. So John stood up, he asked the crowd to forgive him of his sins. Apparently he had found God while in jail and so he wanted at first to be pardoned, but when he wasn't pardoned, he accepted his fate and was executed with dignity. For his wife Lavinia, it was a different story. It is said that she had a really hard time walking. And so the executioners, the gelsmen, they had to carry her up to the podium. And when she got there, she was dressed in a wedding dress, her wedding dress. Now this is peculiar. Usually when they, people were executed, they were given a simple garb to wear and for some reason she was able to talk her dealers into allowing her to wear this wedding dress. The story goes that she did this for one of two reasons.  Therefore she could not be executed. Another side of the story is that she was dressed in her wedding gown because she wanted to be the bride of Satan. When Lavinia Fisher finally realized that there was no hope and that she was going to die, she stepped up onto the pedestal and she looked at the crowd and she said, if anybody has a message for the devil, tell me now and I'll take it to him myself. And with that she kicked out the stool from underneath her and she swung out over the crowd. The demonic ghost of Lavinia Fisher still haunts the old city jail, which is technically the most haunted building in all of South Carolina. She apparently haunts the courthouse and she apparently haunts some churches too. And with this story, Lavinia Fisher became America's first female serial killer or was she?  But a lot of historians now believe that the story of Lavinia Fisher being a serial killer are simply urban legend and frankly, bunk.  So when I decided to tell you this story, I thought, okay, well I know this story, this should be pretty easy, but I am gonna do as I always do, do a little due diligence and do my research to see what facts I can find about this legend. And as it turns out, a lot of the story probably is urban legend. Yes, Lavinia Fisher did live in Charleston, South Carolina. Yes, she was married to John Fisher. And yes, she possibly ran an inn for wayward salesman. However, truth sometimes is stranger than fiction. It appears that Lavinia Fisher along with her husband, John and some other people in the area were part of a gang of highway robbers. Now back in this time in South Carolinian history, to be convicted of highway robbery was a sin, a crime that was punishable by death. And I think this is where we started to get a little bit confused in retelling her story. For all I know for today in 2020, for states that have the death penalty, there are only two crimes that make you eligible for capital punishment. The first is obviously homicide, murder. The second is high treason, that's it. So as you can see, if you're convicted of robbery nowadays, you're not gonna get the death sentence.  But in this time period, it was a crime punishable by death. So historians who have studied John and Lavinia Fisher say that she never was convicted of murder. There is no court records that talk about her murdering her guest. In fact, we don't even know for sure if she owned an inn. All we know is that she was a part of a gang of highway robbers. Now this gang did work between two houses. One was the five mile house and one was the six mile house. And the six mile house is the one that has been given the title of perhaps this inn she ran. But we don't know that for sure. That might be part of the urban legend as well. We do know that when Lavinia Fisher was convicted of her crimes and sentenced to death, she did say to the judge, oh, you can't do that. It's against the law. And he did in fact say, I have a way around that law.  We do know that in the time period that the Fishers were held in jail and at this point, men and women were held in the same jail. They were not divided. So John and Lavinia Fisher were kept together in a jail cell. And during their time of appeals, they tried to escape the jail. And it is said that John Fisher and Lavinia used all the cloths they had to create a ladder to climb down out of the jail. Apparently the jail wasn't very well guarded at this time. And apparently John went first and he got down to the ground for freedom. But then the cloth broke and Lavinia couldn't get out. So John turned himself back in so that he could be with his wife. Poor John, because it seems that Lavinia was kind of scheming all along. If she did have her wedding dress on and she was trying to bait some man to marry her so that she wouldn't die, she wasn't obviously thinking about her husband. She was thinking about herself. But here's the thing. We don't know for sure if she wore a wedding dress or not or if that is again another part of the story that has evolved over time. We do know that the execution outfits that everybody wore were basically white robes. So it's possible that that's how this tall tale started. Now it is actually believed that she did say if anybody has a message for the devil, I'll take it to him myself because we had journalists there at the time that reported it as so. So if Lavinia Fisher and John Fisher were not serial killers, if all they were doing was robbing people of their possessions as part of this gang, then how did they get caught? This is the side of the story I obviously had never heard before. It appears that the town of Charleston were very aware of what the fishers and their cohorts were doing outside of the city. Many a times the people of Charleston had pleaded with the authorities to go out and make an arrest, but without any evidence or eyewitnesses, there was nothing they could do. And so a vigilante group of Charlestonians, and I'm not promoting vigilante groups, however, this is how the somewhat true story is. This vigilante group went out to the fishers property, they cleaned them out of their house, kicked them out, basically made a big stink, and they left somebody by the name of David Ross at the house to guard it for when the fishers and their cohorts returned.  In the crowd, David Ross saw Lavinia and he recognized Lavinia. At this point, people didn't know that Lavinia was part of this as well. After all, she was just a woman. And David looked towards Lavinia pleading for help that she would come help him. And she didn't. She started strangling him and beating his head against a rock. And eventually David got away and he ran back into the town and told the authorities what had happened. On top of this, another man, supposedly by the name of John Peoples, who was from Atlanta, was coming into Charleston as a salesman. And with this part of the story, it does ring true that the fishers did own an end because he stopped at the end. Now, when he got to the fishers end, they said that there was no room available, but he could come in and have dinner. So Lavinia started to make John dinner and John Peoples, that is. And at the end of the dinner, when she had picked enough information out of John Peoples to realize that he was a wealthy target, she all of a sudden, out of nowhere, they had a room available. And so they offered this room to John Peoples. Well, he accepted and before he went to bed, Lavinia Fisher offered him a cup of tea. Supposedly this tea that she offered her guest or her traveling salesman or people that just stopped at her house along the way, we don't really know, was where the oleander root was kept. Now, if she was not murdering people, then this oleander root was literally just to knock people out so that they could take their sales stuff to bring to Charleston. Well, John Peoples already suspecting that something was off. Also, luckily for him, did not like tea. And so as to not be rude when Lavinia turned around, he dumped the tea in a plant and proceeded to go up to the spare room. Well, John Peoples was sitting in a rocking chair. He decided he felt really uncomfortable and so he didn't wanna go to sleep. So he sat up in this rocking chair trying to stay awake the whole night. Well, in the middle of the night, something happened. Big loud sound in the bed dropped to through the floor into another room. John woke in his chair, startled, climbed out of the window and ran back into Charleston to again tell the authorities what had just happened at the Fisher's house. Apparently with this legend of the story, the Fisher's had a lever that they would pull and the beds in all these rooms would drop down into the floor. Some people say that they dropped the floor and John Fisher would stab them to make sure they were dead or that the bed would drop on spikes. Other people say that John Peoples' encounter, his testimony was that he witnessed what was happening with David Ross. And in fact, the only thing we know for sure about these two men is that they were eyewitnesses to highway robbery, which again was punishable by death in those days. So here's my opinion. I do think Lavinia Fisher was a serial killer. I do think her and her husband murdered these men.  It's just common sense to me. I feel like that if Lavinia and John Fisher were a part of this gang of highway robbers, which they were, we do have that. We know for sure they were charged with highway robbery and they were part of a gang of people working together, then how are they gonna complete the task of robbing people and selling their belongings without these people testifying that they had been robbed? If highway robbery is punishable by death, wouldn't you make sure that the person that could turn you in was silenced? So I tend to believe that they were killers as well. They were sentenced to be executed. So the crime of killing, it was paid for by their deaths anyway. Now I do not believe that there was some lever that pulled the beds down. That part of the story, it doesn't make sense to me. It sounds like that story, I can't remember the name of it about the barber of Fleet Shop or whatever in England where they would drop the people and you know what I'm talking about. Anyway, I just think that it's just common sense that they probably killed these men too. And I tend to lean more towards that, yeah, maybe the bones were found by dogs, by hunters. So anyway, that's the story of LaVinia Fisher. I actually think that it would make a really good movie. The story of LaVinia Fisher, she was a bit of a femme fatale as it seems, probably a total psychopathic narcissist, but I mean, I never knew the lady. I've never even seen her ghost. Have you seen her ghost? Are you from Charleston? Have you experienced the demonic hauntings of LaVinia Fisher? Let me know. Anyway, thank you guys so much for our second story time. I appreciate you guys hanging out with me and letting me tell you that story. Again, special thanks to Josh McKay for our music, to Todd Roderick for editing. Thank you to you guys and I will see you soon. Bye.


At Angling Active we have the Shimano Rare-Nium CI4 Plus, available in four sizes from 1000 to 4000 for the 2015 season. CI4 Plus is a composite material exclusive to Shimano and is as hard and resilient as metal but weighs significantly less. Shimano have developed this material from their advancements in competitive bicycle design. In addition, CI4 Plus Magnum Lite further reduces weight, but this time in the rotor, with the additional advantage gained, is improved winding sensitivity. The smaller three sizes have a 5 to 1 gear ratio, the 4000 is a 5.2 to 1, and through the range drag ratings go from 3 to 11 kg. X-Ship Gearing combines six shielded A-R-B bearings, producing ultra-smooth performance with a maximum winding efficiency. The Rapid Fire waterproof drag helps you adjust the drag quickly without making too many turns. The spool has a patentant design where the lip allows line to leave with smaller coils and less friction, decreasing drag and increasing cast distance.

So good morning everyone another day here of depth conf in Taiwan It's great to see you here in the morning and people are still streaming in into the venue and we are Having here the first talk of the day in the room sheshawn which with George Kazna da but there are different ways to pronounce the name for example It's a Turkish name so it could be Hasna da but like if you speak it in French where you are living in France, right? Then you could also say Kazna da, but you can also we can also call you just a George. Yes, okay This is great. So thanks for being here and you're having two sessions So one session today and one session tomorrow is a workshop tomorrow And people can attempt the workshop even if I did not attend the conference today. Yeah, so So yeah, it's great to have you especially because you have been working over many years already with People in Asia for example in India and Praveen Kumar and others So and we're really looking forward here and with more details from your talk So a round of applause for George. Thank you so the title of the conference is pocket debian in my school and so I just take pocket debian and I shall be talking and Rebooting my computer in real time. So This will be just a minute I developed a debian pocket because there were issues with Using debian on computers in my school All the teacher did not want to have a foreign system They just prefer Windows OS and the rooms are used by every teacher and So there is some mainstream and I struggle against that mainstream culture But with the students it is way easier Because every machine has been configured in my school to boot like mine That is it will recognize immediately when USB stick has been switched on and boot on the USB stick So just a minute my students are generally Surprised to see how fast The boot can be so I have the complete boot Screen here I make just a little adjustment In order to have the same image on my computer and on the common screen so Screens This one should be I start my talk again So this one So here it is I am teacher in Dunkirk, which is the Northest part of France and in lycée Jean Bar. I belong to a few Organization and association a full April which are free software organization in France Offset which used to be an international free software association and I am Debian developer for a few years So teacher side when you use computers in French schools How can we know that something is useful just break it and what it is broken You see immediately whether it was useful or not As I am in charge of the school network My colleagues asked me whenever something breaks. So here are the question in Order of decreasing importance The first thing they must do is to take the attendance. So if that doesn't work They are lost Then I cannot access internet The computer is way too slow No, but that's window. I explained them But they cannot hear it. I Cannot print PDF files. Oh, that's quite a new feature of our school computers the printers are windows based and I Don't know why the drivers are not correctly configured. I cannot read my USB stick because all colleagues come with video or images or Short talk on a USB stick and there are often issues then the student size So first question nothing works. Oh, it should be very easy, but When nothing works, I have nothing to do. Oh very well, but Unfortunately I come and everything works again and my password never works. So this is the second line of defense But I can change the student's password. So that doesn't the computer is way too slow So this is always about Windows which is making We don't know what Where is the application it is the last line of defense of my students They don't find the application then all my work suddenly disappeared. Oh, you know students never say they work so it is the ultimate line of defense but so and Just a remark. How can be this computer so old? You know in French schools generally computers are five years old or even more and young people look to have like to have just breaking news This computer is five years old and That is interesting. It works very well when used with Debian I have been pushing newly new solutions for a long time in my school With the few success Between 2005 2010 We had the complete room Using Gnolinix it was a distribution to make physical measurements and a few teacher Teaching that curriculum so each of them knew the peculiarity of this room And they knew that it was not windows, but that did not disturb Them so they could use it and it worked Later More people came in the same room because of the curriculum has disappeared from French programs and then they are required to use windows because My operating system was very foreign However, the US issue Nowadays every people is using Android. So people are not Rigid as they used to be so when something new appears they just adapt However My colleagues are still resisting the change. For example, all of them want Microsoft office, I don't know why because students only have access to LibreOffice Fortunately enough both are compatible for the files issued by teachers We can suspect that this is due for to Microsoft Landing free as in free beer free licenses So this has got a long success Among the oldest bootable media based on Gnolinix, you can count we freed a city it was live CD room with an educational distribution It was made by members of the association offset between yours 2002 and 2007 and the most successful release Which was tempt version 1.5 has been downloaded from a source for more than 100 or thousand times in year 2005 The feedback we got Taught us that People enjoyed Empowering old computers in a virus safe environment Because in primary school, which was our main target Computers may be 10 years old and at that time They were using Windows 95 in 2005 and you can imagine how many viruses they got every day So for 10 years now bootable USB sticks are more convenient than DVD ROMs Just become because one can save some personal content on them and So it is slightly customizable Freduc USB is the hell of Freduc city you have here Useful you are L usb dot Freduc dot org You can find every explanation here It is a derivative of the Canopix distribution made by Klaus Knopper, which maintains this custom Debian distribution regularly Used to be one new version each year at least I remaster it at a deep level So I uncompressed completely the file system make some changes and fold it again How do my students react to such an environment? So when they see that for the first time They It is easy to Save them just use the USB stick plug it in and start your computer After a lot so it's not that difficult and as far as I could see The tame of adaptation of my students is roughly 20 seconds Ten years ago they sent me oh the windows is a bit strange Nowadays they are very proud to recognize Gnolinx, but because they know something about Gnolinx. So teams are changing As they generally succeed to do the work I assign them they are proud and I say them that they are officially becoming hacker and hackers Girls appreciate to hear the name hackers, which is the feminine form of hacker in French language I don't have enough time to develop the few application we have here I shall show you in the last minutes or during the costume session. So there are some specific Scientific applications here pie acido basic. It is about chemistry Jonglage, it is about mechanics of the point For example, you can take a film of somebody playing with balls for example football ball and make Make a simulation Using the rules of physics and see how it works Pie make a video. So this is about measurement on video files, but there are many of them Let us take let us talk about Scientific experimentation During the workshop I shall mostly talk about The XPI's box which our chairmaster knows because we are working with that So this box features Something like no oscilloscope with four channels and a much much more, but back to Experiments, you know that currently people make confusion between science and faith Both are different things If we go back in European history the Maybe you know the history of Galileo Galilei Who was shoot because he pretended by our was turning? at the same time the holy office that is the Christian Topmost authority Used the books which are not really free license Free licensed It is Bible. You cannot change the Bible if you are not in this topmost office so Galileo we were shoot and On the contrary he was proposing free science because people Were invited to recompile his knowledge Of course you needed some drivers some Hardware you needed to have something to Absorb the sky So we did not see by my cavideo and Wanted to make the focus on expires So it is a small embedded system when I say it is more it is real small this size and Around top when my students drop it it still works. Okay, that makes a big difference With the oscilloscopes Just try to throw an oscilloscope and you will see whether it works Longer so this one is released and the free licenses both For the software and for the hardware Currently there is one free license for hardware which is released by c er and The OHL license is a good license for free software Ah students who have to learn coding and programming Recognize that new Linux is a good distribution because it was made by hackers and Targeted to hackers at the begin. So you can find acute tools that that is for example If you want to make something in a cook You can use a knife. A knife is something sharp. You can do very precise things with a knife When you are using Windows tools, it is like making it with a spoon Very difficult to make sharp things with a spoon And you have loads of libraries just one apity install away When my students are using Windows, they generally use not pad plus plus They use B stick comes with a Gini pre-configured and they have quite the same environment and Most of the teachings begin with JavaScript and Python more precisely Python version 3 However to feel the advantage coming with Debian they must to be somewhat advanced so They need to have a personal project and then they feel the gain of having powerful distribution So that's all We can begin the question session if we have some time left. I just deploy here view of educational applications Coming with the Debian pocket So are there any questions? Yeah, there's a microphone from you Do you have any reason to use? Knopics instead of Debian live which is in my opinion is more easy to configure and so it is just an historical reason When fast live distribution existed Knopics was among the first and Freduc city was just a few months before it was based on an over Live system which was made by Raphael Herzog But we stick to Debian a tool no pics because of that and I am trying to use Debian live Which is a powerful system. So I Could make the same distribution, but at some time it's broke I did not understand why so I must learn it and I feel it is more powerful Yes, you are right. I'm not sure. I just went for several years ago to remastering topic CD And I think this process is quite Stressful and Debian life is yes. Yes. Yes. I I know So we have one minute left some other question Thank you for the talk Have you already looked at Debian edu? so We should begin to work together The reason why I did not collaborate with Debian edu is because in I am not rude in my school So I cannot deploy a system like Debian edu. We already have system based on Debian but with some proprietary additions and That cannot be changed so I focused on Developing an environment with educational application which Debian edu is not currently There are a few links to Educational application for and users, but the main focus of Debian edu as I Thought maybe it is different now is rather for assist admin Working in schools. Okay. Yes, you're right about the main purpose. I managed to To deploy it actually in just in one room in one in one classroom and It helped me to deploy Lftp, no Booting booting via network. Yes Yes, that was the way we booted in the room which I must Give back to Windows in the past. So Unfortunately, this is ancient history for me But maybe that can change because times are changing students are knowing Increasingly aware of no Linux and maybe young teachers know how it works. So as older teachers Finishing the career Maybe some change will happen soon and we shall work together. I think it is the way to go Thank you Okay, thank you very much and a round of applause for George. Thank you for the talk Thanks


This research examined the effects of hydrokinetic turbines on fish behavior in rivers, estuaries, and seas. The study found that fish were able to pass around and through the turbines without being affected by their presence. Additionally, fish avoided the turbine's vicinity and its low velocity wake, which indicated that they were aware of the turbine's presence. These findings suggest that hydrokinetic turbines are not likely to pose a risk to fish migration in rivers, estuaries, and seas.

Thank you, Mr. Abbey, and thank you, ladies and gentlemen, for this opportunity to talk a little bit about SES83, as Mr. Abbey has just alluded to. It turned out to be a much different spaceflight from what we'd anticipated, but no less important in the sense that it gave a chance for all of us in this room, and in fact, all the NASA centers, the people who are listening to me around the country, to do what NASA does best, and that is, when a problem crops up, people spent that whole weekend of April 5th inside mission control working that fuel cell problem, coming up with options, coming up with ideas, trying to solve the problem, presenting options to the mission management team who then decided, hey, the right thing to do is to come home and let's think about it more when we get the crew and the vehicle safely down on Earth, and then we'll fly them again. So kudos to everybody in this audience and throughout the country who made that safe return of the vehicle and the crew a possibility. What I'd like to do now is introduce the crew perhaps in a little bit more depth for you. To my right is our pilot, Lieutenant Commander Susan Still from the United States Navy. She filled those very important front-right seat duties magnificently. It was her first flight and we were lucky to have her on board this mission. To her right, Dr. Janice Voss. Janice has her background, her academic degrees, her advanced degrees from MIT in both Aero and Astro. She was able to bring that academic background together with two prior space flights and the experience made her the right person to be a payload commander on this crew. To her right is mission specialist number two, Dr. Mike Gernhardt. Mike's a unique individual in the sense that he has a background academically in bioengineering from the University of Pennsylvania, but he combines that with a lot of hands-on operational experience as a professional deep sea diver in the patrolling industry for a number of years. So I made him the right person to apply those skills as on the blue shift, the shift where Susan and I were sleeping. He was in charge of the orbiter and keeping the orbiter safe and running as a space lab while we were asleep and he ran the blue shift for us and did a great job there. The other experience, very experienced space flyer that we have on board is Dr. Don Thomas. Don has a background in materials science specializing in the semiconductor industry degrees from Case Western and Cornell and then a stand in the Bell AT&T labs prior to coming to us at NASA. Don and I had the very unique experience of flying together on our first flight on STS-65 back in 1994 on a mission which was very similar, almost identical to this one. Dual shift, long duration, laboratory mission. So we were able to bring, and Don in particular was able to bring that expertise to bear on STS-83 and it was magnificent having him and his experience on this mission. The last two individuals that I want to introduce to you are important in the sense that they were brought from outside the astronaut crew office because of their particular expertise. We have Dr. Roger Crouch, degrees from Tennessee Tech and Virginia Tech and his background is he was in charge of the NASA material science program for about a hundred years, is that right? Yeah. He was up at NASA headquarters really managing the material science, the microgravity science program for all of NASA for a number of years. So this was his opportunity to come back and apply not only his top level skills but also his hands-on researcher skills in the laboratory environment. We were lucky to have him on board. Finally, but certainly not least, we have Dr. Greg Lenteris. Greg has degrees from Stanford and from Princeton. His specialty is fire, combustion, which was important for this flight because that was one of two particular areas that we were trying to target all of our experiments on board Columbia and on board the microgravity science laboratory. So Greg was the right person to have on board that mission and he too on his first flight did a great job for us. So that's the crew and what we'd like to do at this time is roll the film for you. We have an 11 minute videotape to kind of show you what we plan and what actually happened on STS 83. Here's the patches designed to show in an artistic fashion combustion science and the material science that we were on board to do. Around the crew one more time, Susan Still, the pilot from Augusta, Georgia. There's Mike MS2, the flight engineer from Mansfield, Ohio. Janice Foss, payload commander from Rockford, Illinois. That's right. Cleveland, Ohio's representative, Don Thomas. Roger Crouch from Tennessee. Greg Lenteris from Numerist, New Jersey. So finally, the big day we've been training so hard for has come and what a beautiful day to go into space aboard Columbia. As we're all getting strapped in, I find that I'm not nervous at all. I'm mentally reviewing procedures and waiting with excitement for when I get to start moving switches in preparation for launch. Six seconds prior to T zero, the three main engines ignite and throttle up when the computers see good engines, the solid rocket boosters ignite. And there's no stopping us now. The vibrations I felt during launch were less than I had anticipated, which was nice. The acceleration off the launch pad was less than I've experienced catapulting off of aircraft carriers. But soon things got pretty exciting. When I started feeling the G forces build up pressing down on my chest, I knew I was accelerating faster than ever before. Zero to 17,000 miles, 17,500 miles per hour in only eight and a half minutes. Now that's pretty exciting. Now we're over 160 nautical miles from the Earth's surface. One of the first things we need to do when you get up into orbit to get into orbit configuration is open the payload bay doors. The shiny surface on the inside is a radiator. And we use that to get rid of the waste heat. I'm sure most of you know how all that works. But we have to get up with just a few hours or we have to come back because of all the waste heat that we generate on board. The next major activity for me and the payload team was getting the space lab activated. You see Roger coming in on the left there. I'm right behind him. This is our first trip into the space lab module after getting up into orbit. You can tell it's early in the flight because the module is still nice and clean. Everything is still packed away. That'll change pretty quick as we get things set up for flight. We have to get all the systems activated, the subsystem computer and the experiment computer, get that up and running so we can get heavily into science. You see Don Thomas here working on the world map computer and you can also see the space lab computer next to him. What was happening on the ground at first unknown to us but briefly made shortly made known to us was that we had a fuel cell two problem. Fuel cell two had high sub stack delta volts, which is a technical term for saying that there's the possibility that fuel cell two could have a fire. So at the upper right hand part of the screen, you see the flight control team meeting together trying to go over options, figure out what the right thing to do. The mission management team met and the right thing to do was to come on home. And here you see Chris Hadfield, our capcom telling us come on home on day four.  And when the first things to go back into space lab module was the lights. And you can see here I'm working with a flashlight in my mouth that was standard operating procedure for us back there to look at procedures and see what we were doing. And it made for a most interesting work experience back there. Before things got quite this interesting, the 32 science teams working in the payload operations control center at Marshall Space Flight Center had started replanting the scientific experiments. And the red team went to work doing the new p cap or the new plan for how the science was going to be carried out. The orbiter crew chipped in here. You see Susan helping on a Japanese furnished large isothermal furnace for some of the material science experiments. Greg's are doing some combustion here. Oh, that dawn doing material science still on the large isothermal furnace. I apologize for that. He's changing the samples here going with some of the samples that had shorter run times than what we'd previously anticipated doing. And you can see that he's working from a new p cap that had just been backed up that day. Mrs. Greg, sorry. Combustion was one of the important areas of research on our mission. And what I'm doing here is a suit formation experiment. So of course, is an important airborne pollutant. This is the igniter in the combustion chamber. You'll see the flame and ethylene air diffusion flame lighting. It's actually upside down here. It's forming soot. Our job at this point was to adjust the flow rate of the fuel in order to eliminate the suit formation and bring it just below the suit point. So the flow rate is being adjusted down. The next image is a laser extinction image of the same flame. And this is what the scientists on the ground used to quantify the suit formation rate in this particular flame. Another area of research was droplet combustion droplets, of course, are ubiquitous in many combustion using devices. I'm setting up the experiment here. In the next image, you'll see an actual droplet burn. The droplet is formed in between the center needles and then it stretched, released and then ignited. And then it burns from the burning rate of the droplet, the scientists can understand the chemical kinetics and the physics of the burning process. The next image is an ultraviolet image intensified. And you can see that the droplet burns all the way to extinction, which is exactly what the investigators wanted to try and see. I spent a lot of time during our four days working on the glove box experiments here. And this is one of the material science one from Northwestern University. We wouldn't have been able to do the great job we did up there without outstanding support here on the ground, both at the Johnson Space Center in Huntsville, Alabama at the Payload Operations Control Center. And our number one man there working with us was Paul Ronnie, our alternate payload specialist who did an outstanding job helping us get all the experiments done in time. We had a couple of experiments on board that were looking at hardware we might be using for the space station. This is an example of how we could upgrade an experiment as the station evolves, as you learn more about the science or improve the hardware to allow you to change experiments over the course of space station's life. This is the combustion module where at the beginning of the flight inserting the experiment mounting structure for the soot flame that Greg was talking about earlier. Halfway through the flight we'll change these out and put in a flame ball experiment that would be the second half of that combustion experiment. The very first full day on orbit, one of our first jobs was to activate some protein crystal growth experiments. And that's what Dawn and I are doing here. Protein crystals of course help the scientists on the ground understand the structure of the proteins for which they can then design drugs. Our job was to photograph the 35 millimeter photography, the activation process. One of the major challenges facing a 7 person crew like we had is to convert the ascent rocket into an orbiting laboratory. And basically you're trying to stow away about 10 pounds of potatoes in a 5 pound sack and then deploy all the various experiments. This is Janice taking an air sample in the lab, one of the tasks we do when we first activate the lab. And then here you see me working on the computer and I'm completely upside down on the ceiling and that's one of the things that we did a lot of is to try to spread the people out. Seven people on the middeck don't fit very well on the floor. Of course we have to get exercise and there's Jim doing the ergometer. Our exercise periods were compressed because of the short flight. But normally this is a very important part of our day. As you might imagine the view out the window was pretty impressive. This is the Baja Peninsula which is oriented kind of upside down. The United States is towards the bottom of the screen with Mexico up in the upper left-hand corner. This is part of the Middle East with the Nile River in the top portion of the screen. The Red Sea in the middle and Saudi Arabia towards the bottom. It's one of the prettiest parts of the world I think. This is Sinai Peninsula in the same area with the Gulf of Suez and Aqaba. You can see the Suez Canal up in the upper left.  They go down thousands of feet to bring up water for irrigation. One of the most spectacular sites we got to see from our short mission was Comet Hail Bop. Which you're looking at as a sequence of pictures here watching the comet actually set through the atmosphere and we're actually able to see it set beyond the limit of the earth here. You can see also the orange lights there that are down on the earth. Those are fires burning over Central Africa as we passed over there. The sunsets are spectacular although they're very short and they occur over like 10 seconds or so we get to see about 16 of them every day which makes up for the shortness. Well after a lot of unexpected quick work we had the vehicle and ship ready to come home. Here we are on the orbit day everybody suited up. Susan left flight engineer Mike there in the in the middle of me on the right. We did the deorbit burn. Made a safe and successful to fuel cell entry back into the earth's atmosphere and about this point at about Mach .9 is where I had the opportunity to fly the space shuttle for the first time. I had about 1000 practice shuttle training aircraft approaches but I had never as pilot had the opportunity to actually fly the shuttle and when I first took control of the vehicle manually I did a little pitch pulse to see how it flew. No roll pulse and I told Susan hey it's just like the STA and I think that's a tribute to our training people and system that a first-time flyer can feel that comfortable. Here we are rolling out on final approach. Don got a good view of the runway out there over over Susan's shoulder. At 2000 feet I did the preflair and at 300 feet Susan dropped the gear down. Right here we had a little bit of crosswind from my right to left as I was looking out the commander's window that was causing some concern by the people on the ground and you see that I did have to make a little correction back to the centerline to the left here and then stopped the rate by dipping the right wing down to have a zero cross the runway rate as we touched down. The vehicle touched down the whole landing task was well practiced in the shuttle training aircraft and I felt comfortable with it. As I lowered the nose Susan put the shoot out and the shoot causes a lot of drag or at least it seems that way after several days of zero gravity.  Susan drops the shoot at 60 knots and I do use the brakes here for about the first time to bring it to a full and complete stop. I found the brakes they weren't dragging I did find the nose will steering to be a fairly stiff in the sense that it reacted very quickly to any inputs that I made. After that after about an hour of medical testing we were able to get out and wave to the photographers who were gathered and here's the final word. Thanks to the hard work that's going on right now at the Kennedy Space Center that to be continued slogan is going to be true. On July 1st they're going to have the vehicle and the payload and us back out there and ready to go again and it's happening only because of the hard work that the engineers and the technicians down at the Cape are putting in on this unprecedented and record-setting turn of the vehicle and the payload. What we have next are a series of slides of some of the more interesting Earth observation sites that we that we were privileged to have the opportunity to look down on from about 160 nautical miles. This is Long Island the northern half of Long Island in the Bahamas and we didn't have a whole lot of time to look out the window but when I when I could I would look down particularly on the Bahamas which to me is the prettiest place in the world. Here you see the tongue of the ocean on the right hand side with a with a the shelf drops off from about 60 feet down to 6,000 feet and the picture doesn't really do it justice. I remember when I was in space looking at the window and just really awestruck at the beauty there and thinking that the only the second place in the world I don't want to be is there the Bahamas. The first place was was on the spaceship at the time and fortunately for us we landed we debriefed for a few days and then got two weeks off so I went straight down there and actually did some diving at this location and it was really special to to go underwater and see that environment and having your mind the same image of that place from space. It's very very awesome. This is the Nile River in Egypt and as you pass over Egypt and you see the brown deserts below you the two things that stand out one of them is the bend in the Nile River here at Luxor and what you're looking at is the Nile River on either side of the river itself. You can see the green agricultural areas where the growing crops all along the Nile and this is where the Valley of the Kings is where they found the King Tutankhamen and they're still discovering new tombs there today. Next. Another spectacular area on the Nile River is a little further down is the Aswan Dam and Lake Nassar here. The dam is just near the top center of the picture you can see it barely there a little gray structure crossing the Nile. The water levels were at near record level here when we flew over the Nile and Lake Nassar. It was due to the heavy rains that they've been having in Kenya over near the headwaters of the Nile since December of last year. This is the Indus River in Pakistan and what the scientists on the ground like to see from photos like this is the level of water in the rivers and the agricultural the amount of area the agriculture extends from the river boundaries and the buildup of the cities surrounding the river. This is the Mayan volcano in the Philippines it's the most active volcano in the Philippines. You can see the smoke still coming out the top it's erupted 47 times since the early 1600s. The most impressive part about this picture is that we were able to take it because typically there's cloud coverage over this area. They're reminding me that this is the gray well breeding ground located on the west coast of Baja. Now I'm not going to tell you that we can count whales from space at least 40 year old eyes can but what we can do is get the big picture that is what are the plankton blooms like what are the other large scale current changes that might be affecting the gray whales as they migrate down from Bering Sea down the coast of North America to this area where they feed and breed to begin the cycle for a new year. One thing that I always find fascinating is how you look at something from space and remind you of some small thing but you're seeing it on a much more tremendous scale. I see a picture like this and I think of a pebble in a stream. This is what looks like to me but what you're seeing is the peak of Guadalupe Island interacting with the atmosphere to create this wake on the leeward side of the island. I think it's fascinating just to watch how these things develop and how some really look to something as small as a pebble in water but the scientists can actually tell a lot about the environment around this island from an analyzing picture like this for example because the wake downstream of the island is a solid cloud bank they can tell that the winds at this time were less than five meters per second. Had the winds been higher you would see turbulent wakes like you see behind an airplane when the air is kind of humid and you'll see you actually see the wakes forming off the wings and you'll see the air the cloud patterns disturbed behind there with von Karman vortices forming. Since there are no vortices here they can tell at this time of year and these are other conditions the wind speeds are fairly low. We were fortunate enough especially myself who was the first time flyer to have Jim Halsall constantly telling us when things were happening that we had to be sure not to miss. Roger and I and the other crew members were spending a lot of time back in the laboratory but Jim finally said to me Greg come on up to the flight lab to the flight deck because you have to see at least one of these before we can go home and so I came up and this is what I saw it was a sunset and the difference to me was that you see this very very deep and gorgeous red at the same time as a very very bright almost a neon blue during the sunset and for me it was very very spectacular and beautiful the slide is good but it was even brighter and more gorgeous in space. Sometimes you go in and out of sunset you're able to see a little bit of three-dimensional structure and here you see the class Genesis the cloud formations and the changing cloud formations are always very dynamic and interesting here you see a cloud cover coming out of that cloud cover is a huge thunderstorm that's just balding up and in the sunset the glint off of that just gives it sort of a surreal kind of a quality.


If the love of the Lord Jesus Christ can't compel you to put your faith and trust in Him, to turn from your sin and to serve Him with heart devotion, then heaven help you because no one else can. The Lord Jesus Christ is the Savior of men. The love of Christ has come. He has given Himself on the cross. He has died for sinners. Himself paid the penalty for their sin. The wrath that they justly deserved was poured out upon Him. If that love poured out on the cross by Jesus Christ is unable to compel you, it just magnifies how depraved your heart and mind really are. Doesn't it magnify the depravity of man that that love, that mercy, that grace does not compel us to live heart, soul, mind, and strength for Him?
