 Είμαστε στρύμοι. Είμαστε μανόλες. Είμαστε δημιουργίες για να διεξίσει τα γιγίξα για τα μάτια. Ευχαριστώ για τη διάφορα. Γεια σας, πρόεδρο. Θα δώσω τη διάφορα να δώσω τα δουλειά που δώσαμε σε τέτοιες χρόνια, να διεξίσει τα γιγίξα για τα μάτια, και να διεξίσει τα γιγίξα τίποτα. Από να ξεκινήσω με τα μάτια, θα θα τραπεντάρω μία πρώτα και θα πω τι η παντια είναι. Για να παίρνω ακόμα some things about bush trapping, αλλά θα θέλω να μεταλλαστούσαα μία πιο δημιουργία για τα γιγίξα αυτά, όπως θα πω, είναι μία ακόμα, να κolytum είναι πιο εξίγιο κύριο, να κolytum θέλω να ήταν πιο εξίγιο, για να κάνω ένα πιο εξίγιο και να μπήσω ελπιέση. Τα πρόκειση είναι πώς θα διεξίσετε τα πρώτα πακάτια. εργο开始 φυσικής. Στοιχώ από τα δύστρονα, το κα блиσα σε τώρα. Σε αυτή τη δυο με την οποία έχεις δεξεία, πιο ανάπτυξη, κάτι όργο, τεχνικά, βόση στη ΑΕΚ, είναι σύστη. Θα το χρησιμοποιήσεις. Αλλά η πράγματα είναι, να βρεπευτεί με ένα σύστημα, ότι αν κάποιος έ προσπάκεται να ρευτεί τον τεχνικό, παρασχευτικά, ομσόζευος εργασ извαγεία, δεν θα remark. Για την εργασία... Ποντάς. Θέλω να πω κάτι άλλο πρώτο. Αυτό κάνει πιο δύσκολο πρόβλημα. Τώρα το Geeks έρχεται. Θα εξηγήσω πώς το Geeks κάνει. Κάθε σύστημα... Κάθε σύστημα έχει λιψή στον σκόρ. Βέβαια, το σκόρ χρειαζό σύστημα χρειάζεται. Βέβαια, χρειάζεται. Βέβαια, χρειάζεται. Βέβαια, χρειάζεται. Και στο Geeks, χρειάζουμε ένα γείλ, γιατί χρειάζουμε να φύγουμε, να φύγουμε, να φύγουμε και κάθε σύστημα. Το πρόβλημα είναι πιο δύσκολο. Όταν έχεις ένα πρόβλημα στο Geeks, το τέλος δεν θα αφήρεις στον σκόρ. Επίσης, το Geeks έχει 3 λευκότητας. Βέβαια, με το μπιστροφόδο, βρίσκεται ένα κομπιλό, που μάθει μπιστροφόδο. Και μετά, με το GCC-φανάλ, δεν χρειάζεται μπιστροφόδο. Βέβαια, μάθει μπιστροφόδο και αυτό είναι το τέλος. Βέβαια, το Γιάνν χρειάζεται πριν, και θα αφήρει να βρει πιο δυνατό. Βέβαια, θα αφήρει να εξηγήσω. Ξέρουμε, πρώτα, θα αφήρουμε με το μπιστροφόδο. Από την δερειοφόδο του μπιστροφόδο. Σε κάθε σύστημα, όταν αφήρεις, έχεις το GCC, το GLPC, το GCC-φανάλ, και το GCC-φανάλ. Και πρέπει να έχεις το Ταρ, XZ, MakeDir και Bus. Ήσαι να χρησιμοποιήσεις τον Ταρβόδο, και μετά μετά, μες στους δερειοφόδο, θα αφήρεις με το GCC-φανάλ, και θα αφήρεις με το μπιστροφόδο. Και μετά μετά, μες στους δερειοφόδο. Και μετά μετά, μες στους δερειοφόδο. Πολλοί έχουν ρωτήσει με το GCC-φανάλ. Αφήρεις με το μπιστροφόδο. Ναι, το μπιστροφόδο. Λοιπόν, δεν είναι πολύ δύσκολο, as it seems. Φυσικά, μετά μετά μετά. Αυτό είναι το δερειοφόδο, έχουμε όλα τα μπιστροφόδο, και μετά μετά να αποφασίσουμε το GCC-φανάλ. Και μετά να χρησιμοποιήσουμε το GCC-φανάλ. Αυτό είναι για λίνοξο. Βλέπουμε το GCC-φανάλ. Πολύ δύσκολο, δερειοφόδο και όλα. Πολλοί έχουν ρωτήσει με το μπιστροφόδο. Φανάλ, για αμφραίες. Είναι ένα στους δερειοφόδο. Είναι ένα στους δερειοφόδο. Για τρίτος, αμφραίες, είναι πολύ δύσκολο. Βλέπεις το μπιστροφόδο, πω τη μπιστροφόδο, Πω τα βασκάρια, πω τη διεύτερη γραφία, πω τα πατήρια, και πω να το ξεκινάς. Αυτό είναι. Το μπιστροφόδο, για το λίνοξο, 32.64 μπιστροφόδο, είναι αυτό. Δεν είναι μόνο το μπιστροφόδο. Ήταν πολύ πιο σύμπρο. Το μπιστροφόδο έχει ένα πολύ διακοτεχωτικό τεξούσο. Έχουμε ένα μικροκένερο, υπάρχει ένα κέντρο κέντρο called GNU-MACH on the base and then over GNU-MACH you run the head servers. The head servers implement most of the things that some Linux does in the kernel space. So in order to work around the thing that the kernel doesn't offer the same services and it offers the servers, the head servers offer them, GNU offers some interfaces that abstract these strains and different interfaces and everything. So directly it makes things will not work, nobody guarantees that by GNU the things will work the same way. Maybe some apps for example accept some interfaces from proc to be exported from the kernel which doesn't happen. So here's how you bootstrap head on a head system. One last thing. In order to do the first step, in order to build the bootstrap service for the new platform you first have to build the toolchain, the course compiler for that platform which on its own it's a really big effort because Geeks for example had some expected only to design with Linux in mind. I will show you some code later so you can see it with your own eyes. So in here you can see that the head has some, I would say dependencies, security dependencies that you have to eliminate. For example, I want you to see the head headers here, the jillipsy headers there, the head minimal there and the head kernel headers, this is wrong, it should be head core headers, I just used my graph from last year and forgot to change that. It's a package that includes all the headers that you need and then the jillipsy library and the jillipsy compiler. So in order to build jillipsy you need to live by hash from the head but in order to build the head libraries you need the jillipsy. So you can see why it can get hard to and why you should never have security dependencies like NPM for example like I learned yesterday. I don't use JavaScript, I avoid it. Some of the problems that you can find, there are simple problems like path max but it's pretty easy to fix and really hard problems like binaries for I686 new target will not run on the health system. Actually at least when I tried to run them two years ago they wouldn't. Just as you remember when we had this issue but there was something with the jillipsy I don't know, I found that the I586 version worked so I prefer to use that way. As I said before when it was designed had only Linux in mind so I had to change geeks to take into account both kernels to teach geeks to be kernel agnostic. It shouldn't care about what kernel you run. Actually when I remember reading in the head manual that supposedly some time a long time ago you were able to remove the Linux kernel, add the GNU kernel and the head libraries and it would work. Supposedly it should have like many years ago, I don't know what happened and many things like they have specific patches in jillipsy that were not present in jillipsy. Parts of some long forgotten patches that nobody had, this is not because the head developers do not try or do not care. They are really awesome guys, awesome engineers, they know what they are doing, they just need more contributors. Because the head is a little, people laugh with the head but it's a really nice project, it's really something that people should really spend more time and try to help. Because if you really make you learn new things and I will leave it to you to your, and at this time after, this happened at two years, after I finished my G-Shock in 2015 I think, yes. We are at the level that you could run, this commanding geeks, ah yes, sorry. We had an error and with, yes, I'm starting to get a bit nervous so this was the work of two years. Ok, my love is a bit slow so but we have time, yes we have time. Yeah, fuck me, we miss now. Yeah, what's that doing, geeks, you're riding the garbage truck here? It's to the dependence of the package so you can see, yeah, this is it. So, this is what you need to put geeks on a new system, this is the binaries, that's it. So, when we got this, we have to get to the new platform. As I said before, in any Linux system, you update the new geeks, you update the new geeks. You run configure this with carriage here, this option here, it's to tell geeks that you don't support the platform yet but you have the carriage to do it. Ok, but you have to go to the new geeks and you can see that you have to go to the new geeks. this option here, it's to tell gigs that you don't support the platform yet but you have the courage to do it. Beginning building everything, beginning building the world, nowadays it works, we still have some issues with packages that need patches, Για παράδειγμα,ickyC has a patch that fails. C.GyL needs patch how to handle time on the head. I need to tackle this. There are a lot of packages that have really simple errors, like simple test errors. It's all test errors, something that maybe somewhere doesn't work well on the head. but let's say that any one of you wants to try a Gixxon head, you just go, clone, corrupt its branch, make, run a Gixxon your Linux machine, build the Bootstrap binaries, because for now we haven't still yet added to the actual master branch, but they are available on Hydra so you can download them from there. This is exactly what you need to do to run Gixxon on a head, this is it, it's not more complicated than that. Okay, I'll get in a second there. So at that moment currently on a head it's really these patches and everything, but there is still something that I need to work on the head, it's the demon. And the tools that I need to create the Gixxd image, for example Gixx uses some syscalls, some syscalls from like mount, U mount, pivot route in order to create the image and all of these to create the Gixxd image and all of these syscalls do not exist on the head. There's a completely different architecture, what I told you before, where was it? Yes, we have some, the DLPC offers some interfaces, we have on the head we have a unit called mount that can do the same thing, but it's not mount, it uses a very different way to achieve it with translators. I suggest you, there's a very nice paper that explains what translators is on the head, I don't remember the name exactly, it's on the head wiki or he. What I did during the last deshock is write some wrappers using, actually first I set, there's a unit in the head called the set trans, which you can use to set translators. So in order to make my life easier and anybody else in the future, I created a libhertutile library, which is still somewhere in the mailing list that I need to some day finish. That offers a procedure called set runs, you can just call it, you can just pass some arguments and you can create whatever translator you want without actually accessing the insides of the head and everything. It's like an easy interface to create these translators. So I used set runs to create a wrapper for mount, and so geeks, and I changed all the usage of mount on the geeks demon with nix mount. I called it nix because the directory inside that we keep the demon in the source, it's still called nix because we used to share the same demon. Nowadays it's way different, but just for, I would change it when the time comes the name. So I'm using nix mount, and the demon actually thinks that he uses normal mounts, but actually uses the wrapper that hides everything. For the MS bind option that we need I use frimlings, and this last one is not still ready, but someone suggested that there isn't something like pivot root for the head, and pivot root it's not chroot. It actually changes the way that the application sees its root directory. Someone suggested to use fake root, this is still in work, this is not finished, but it may not end up like that. So now on the geeks sd front, why I haven't finished geeks sd yet, which many people are asking me. Let's say that you want to run this command. Okay, if you try to cross build geeks sd much for the head through from linux, you will not be able to do it. Because of the way that the demon creates the derivation of the system creates the binaries. It actually expects to build around the binaries of that target on the system you are building it. This has to change in the future to actually use the cross build binaries to create the image from another image. There is a hack that you can do to work around it, like you can have an offload machine, but it's a hack. I prefer to find the correct solution. There are still some modules of geeks that were designed with linux in mind. So let's say that you say the same command, you want to run from the head this time, and you want to build geeks sd. It first assumes that you run linux, that you have a RAM disk, which you don't. On the head it's much different. There are still other problems that don't have anything to do with geeks. Justus told me that there are some special attributes that the XT25 system should have on the head. Justus has the solution and it works because I'm starting to lose the way of my... Guys, if you really want to help with the port, just try to run geeks on any head machine for now. And try to build packages. There's a guy called Rene Saev. I'm not sure about the... I will mispronounce the surname, I will not say. His name is Rene and he's really doing exactly that. He's trying to build anything on the head, packages. And he's always sending packages to geeks and tries to fix that. All the bit failures, like a test failing, he will find why and he will... Or at least report it. Or even at least report the issues so I can know whatever happens. So I can slowly get there. It's a lot of work. It's not difficult work. I would call it grand work. Yes, yes, yes. Yes, so the current status, you can cross-build everything. Like they say, build core utils. Actually, you will not be able to see anything, so yes, better this way. It's this simple. Right now you can cross-build anything from Linux except it uses every package from Linux to the head by using this. Geeks build, target, the name of the package. If it doesn't have to do the geeks sd, it can be built. I have already more than 50 packages in geeks, 50 patches in geeks head related. I should have written core utils here. I wrote the talk a week ago so I forgot that. The geeks demo as I told you before. And Ludo last week started the cross-compilation job on Hydra. So if you want to build anything for the head from geeks, you will not have to bend your machine. You can just download the binaries. So work in progress, finish the lib here at the UD library. This is the wrapper library I'm using on the demo to mask amount and everything. Making geeks kernel agnostic. And package the head libraries because I have still not packaged the actual head libraries. I have only packaged, sorry, what I needed, like lib by hash. It's the only thing that I needed in order to... It was the head of the lib by hash. The glumach kernel is also somewhere in the mailing list, the package waiting. There was a small thing that I had to change. I didn't have the time to do. Anyhow, the roadmap. Finish geeks sd, linuxims, miss independences. And hopefully I will someday make use of justice work on SEPHERDS. If you haven't seen his talk yesterday on the microcane, please do. That's it. I would like to thank everyone that from geeks shared. Special thanks to René. He's really helpful. Everyone from FSF because this work was from GSOC. So I was working to continue summer on GSOC. It was really nice. I became part of the community which was my target. I want to be part of this community. So thank you guys, everyone. That's it. I thought I was making fun of the head again. I can see like a couple of guys here using the head. Who's using the head in here? One, two, three, four there. Four there. I never said that when it was created, yes, the head was supposed to be the replacement for the Unix kernel. But that didn't happen. But still, the head, unless you want some... Nobody told you to use it as an everyday system. But it's a nice system to hack on and learn things. So don't stay at that the head is not released, the head is not ready. The head can be used. It depends on what you want to use it for. If you want to play games, yes, of course, you cannot play games. But if you want to hack a bit and learn things, you should use it. Give it a try, there's nothing. You just launch a VM, a DebianHead VM, that's it. You don't have to do anything crazy to run it. And especially with the DebianHead installer, it's pretty simple. I even run it on a very metal hardware as well, just for the fun of it. Any questions? No? Ah, yes. Excuse me, can you repeat the... Can you say it louder, because I... Yes, and I'm not the one... I'm suitable to answer. I think Justice will be more in position to answer about the... Justice maybe would do. So currently we are using a lot of drivers from Linux. And that is really tricky, because Linux is evolving so far. And we are trying to use the run kernel, which is basically NetBSD. And to run... To use the driver from NetBSD into the space. So what you're doing is running on a core HIRT. No, what I'm kind of doing is... I'm running Geeks on DebianHead. And I hopefully want to make GeeksSD work, so I can run pure HIRT... With GeeksSD, like Geeks-based HIRT. Okay. I wanted to ask, are there any futures which conflict with Geeks? Because earlier we heard about services management. And I think that also heard about some services management and such things. Or there are any conflicts? That's an interesting question. So the question is, are there any conflicts with the way that... Geeks hand services and the HIRT... I think that only time... I'm not in position to say if it will be conflicts or not. Time will tell. We will see and then we will work around it as we go. Maybe even in the HIRT we will be able to not use the Linux way of doing it, but... Take use of their way of doing it. We will work it as we go. I cannot answer it with certainty. Anyone more? Am I wrong about this? I think the Shepherd manual says it's originally planned to be used for the HIRT, right? The Geeks system services used is Shepherd, which was originally planned for the HIRT anyway. So that vision is not incompatible, I think. Yes, Chris here said about the Shepherd that was designed to be used with the HIRT. But the thing is that... Who used it for the last time? We need to test it in order to make sure that it works. Hopefully it will. We don't know. That's why I don't want to say anything with certainty. I think the question about possible feature conflicts is about passive translators in the HIRT, which is some form of configuration management stored in the file system directly. I think that's what you had in mind, right? Yes, well, I don't know much of HIRT yet, but it was something related to the HIRT. So I think I will have to talk with Das about this question and then better ask it later. So maybe we can discuss it after the talk on my own. Okay, anything else? Okay, that's it, I think. Thank you.
