 Thank you for coming. I forget how many of these we've done so far. Does anyone not enough too many? So it's been really good watching the community evolve over the years and people getting together and sharing ideas and learning from each other. I would like to call attention to the GNU Radio Conference in Charlotte in September of this year. Charlotte, North Carolina in the US. Charlotte is a major airport. You should be able to get direct flights from London and Frankfurt at least and a couple other places. It's always a very good conference. We have the European GNU Radio Days, which I would love to go to except you've scheduled it on top of the embedded Linux conference in the US. Come on in. We're just doing the procedures. We have stickers. Please take stickers. The guys don't want to carry them home. We have a speaker gift of Pluto. Thanks Robin. We will also be able to give some out to people who ask very good questions. So during the talk, think of good questions to ask, and if the jury awards you a Pluto, that's what will happen. With that, is there anything else? We'll stick to the schedule. We have to stick to the schedule because the video recordings are done by time slices. So if you end early, your next talk will start on time, and your talks cannot run over, and we'll do like a five-minute gap in between to change the room. The room will probably fill up and it will get very crowded and very hot, and there will probably be a line. So if you haven't been before, getting in and out can be a problem. If you need food, we can probably send a runner for one occasionally, and if you need mate, we can do the same. So last week, we had a hack fest at Easteck in the Netherlands outside of Leiden, organized by Andre here, and that was a very nice experience and a very nice facility, and there was a wonderful cat. With that, we'll let Andre explain what we got done. All right, thanks, Philip. Yeah, as Philip said, my name is Andre. I'm an ESA employee by day and a radio officer by night, and I had the wonderful pleasure of inviting people to my workplace three days before forced them to have a little hack fest, sit together and hack on radio and related projects, and, right, oh, wait, that's the wrong slides. I have to go here. Right, so the slides are also already online. You can visit this link, and actually if I switch the slides here, it will also switch on your laptop then, so it's kind of convenient for you. I had other slides before already assembled at the hack fest, but then I left my laptop at home, so I had to, yesterday at night, I reassembled everything I could remember. Ah, yeah, 2 a.m., something like that. So sorry if I forgot anything we did at the hack fest. We have a lot of people that were there, so correct me if I'm wrong somewhere. All right, some facts. So it was three days. We had meeting rooms from the 28th until the 30th. We had food and convenient traveling from the next big city. In total, we had 14 participants, including me, and six of those were actually radio officers, so that was a good turnout, I think, from the radio project folks. And we also had a space cat onsite, which helped improve the productivity of everyone attending. And also, at this point, I want to thank my section and my division at ESA Aztec for letting me invite everyone and book the meeting rooms and have this wonderful event. So basically, this is how a hack fest looks like. It's a bit blurry, but yeah, we don't need much. We just need a meeting room. We just need convenient support for food and drinks and then basically some reason to go to a place, for example, like FOSDEM. So if you live or if you have something in Brussels for next year, I think we will be happy to arrange something, right? There's the space cat that we visited and had some quality time with it. And it's actually a real staff, so it has a badge and it can go in and out of the facilities, so no problem there. So what kind of topics were we working on? So we had one group that was basically dedicated three days working on the scheduler in the runtime and it had some high-profile members, so Marcus Müller was there, Bastian Glössl and some other Grenoadio core developers who actually started from scratch and made some progress on that. Then we had a group dedicated to Grenoadio 38 out of three module porting and also coming up with a way how to create a binary package feed for out-of-t modules because right now we have pi-bombs and you have to compile everything from source and it's not super convenient for every end user we currently have out there. And then we also at the last day we had some smaller group that looked at CIG-MF and how to improve the ecosystem in regard to CIG-MF. So the schedule and runtime, so the first day the group had a brainstorming session and basically assembled a two-page document, something like that with thoughts and basically all the collected lessons learned, everything how to write it correctly. And the second and third day they basically spent implementing a first proof of concept and it's actually already a public Git repo which can be accessed at this URL. Right, then for the Grenoadio 38 out of three module porting, we had some features that were implemented for CIG, I don't know, this was, wait, yep. So Zach had some effort actually implementing the QT GUI in OsmoCom FFT, so I don't know, I think a lot of you know OsmoCom FFT and it previously used the WX GUI I think in Grenoadio 37 and now it will hopefully soon after the pull request patches get merged, support QT and so with that also Grenoadio 38 which is a nice effort. So some more plots from OsmoCom FFT, how it looks with Qt. Also Nicholas made an effort to actually have one extra column in C-Gren which displays the supported versions. So if you have an out of three module you can write in your manifest file which versions you support and we will automatically display this in C-Gren now. And also if you have a logo and we click on one of the pages here you can have your logo shown there so that's some small fixes but it's a quality of life improvement for the packages. So also if someone wants to port some modules from 37 to 38 you can just look at the list and pick one of your favorite modules that are not yet ported. Yeah and for the automatic package feed for the out of three modules I was basically looking at that with several other people how to do it the most efficient way and the most efficient way will be probably to add more metadata to the pi-bombs recipes then have a automatic let's say templating script which then templates my Ubuntu or Debian source package files and then we can feed it through some CI pipeline. Which I spent a bit writing the templates and there's also Git repo which is already public but I forgot to put a link here. And hopefully soon I will be able to progress on this in an efficient manner. Right and then on CIG-MF tooling yeah we want to implement and support as many external tools around the Negron Radio ecosystem with CIG-MF and yeah one part of that is for example to have one library or header only library for C++ which has a good packaging in downstream packages so I looked at that and posted the pull request to the DeepSig LipSig-MF repo which improves the CMake and hopefully I get some reviews and get this code merged after the hack fest. Yeah also Schneider did some effort to actually implement CIG-MF in or look at his old code to implement CIG-MF in spectrum so if you have a CIG-MF annotated file you can load it in a spectrum and then have like these annotations displayed inside of your spectrum. Yeah right. Also at hack fest we do fun activities and being at the European Space Research and Technology Center it has some upsides so we can for example watch 3D CGI and real footage of the ISS so basically a nice image movie of us floating through the ISS and also learning a lot about microgravity and why we actually do some space research and also visiting the concurrent design facility at Aztec and learning on about how to actually do spacecraft design in the early stages to get something into space. So conclusions. We have some real progress actual code of generated runtime and scheduler thanks to the folks working hard and not for three days. We have some packages. I actually forgot some packages that got three eight updates because the slides were done tonight. And some more interest in CIG-MF and maybe we get some more tooling done soon. There's an idea to actually have a GSOC also working on that maybe some student in this room or from outside this room wants to work on that as well. And yeah, thanks for your attention and just joined the next hack fest and I don't know when we will have the next hack fest so we are very welcome to suggestions and also if there's some conference or some other event in proximity and there's like three days before that we can have a meeting room for 20 people or 10 depending on the location. Just come up chat with us and we might be able to have another one. Yeah, that's about all I have right now. Yeah.
