1 00:00:02,521 --> 00:00:04,081 Let's talk about GNU/Hurd 2 00:00:05,841 --> 00:00:11,101 For us it's a bit all about freedom 0, that is, the ability to use software, 3 00:00:11,481 --> 00:00:14,161 basically, for any purpose. 4 00:00:14,881 --> 00:00:18,261 And for us, the important thing is that you shouldn't have to ask 5 00:00:18,441 --> 00:00:20,981 the system administrator for things. 6 00:00:21,481 --> 00:00:23,581 You should be allowed to do whatever you want. 7 00:00:24,161 --> 00:00:30,901 So for instance, why is fdisk, mke2fs, etc. hidden in /sbin? 8 00:00:31,142 --> 00:00:36,841 I want to be able to build disk images, play with them, mount them, etc. 9 00:00:37,700 --> 00:00:44,581 So just be able to work with the kind of disk and network access I have, 10 00:00:44,581 --> 00:00:46,041 and do whatever I want with this. 11 00:00:47,161 --> 00:00:52,301 It's about freedom to innovate as well, if I want to use an experimental filesystem, 12 00:00:52,301 --> 00:00:56,921 just play with, without being afraid of crashing the machine. 13 00:00:57,841 --> 00:01:01,421 You should be able to just run the file system 14 00:01:01,440 --> 00:01:06,241 and let the system administrator be happy with this because it's safe to do this. 15 00:01:08,661 --> 00:01:14,181 And also, it's a way to provide freedom from misbehaving programs 16 00:01:14,181 --> 00:01:18,481 like a driver which doesn't work so well, some things like this. 17 00:01:20,581 --> 00:01:25,041 Just to give an idea, in GNU/Hurd, 18 00:01:25,041 --> 00:01:28,882 you have the kernel which does basically almost nothing, 19 00:01:28,882 --> 00:01:33,741 just managing tasks, the memory and inter-process communications, 20 00:01:33,741 --> 00:01:37,821 and then you have a lot of daemons doing the actual stuff, 21 00:01:37,821 --> 00:01:43,861 so the pfinet is the TCP/IP stack, and ext2fs does the filesystem thing. 22 00:01:44,381 --> 00:01:47,502 And then, you have the user, just running programs. 23 00:01:48,581 --> 00:01:55,321 And these tools just, actually just talk to the daemons through the microkernel, 24 00:01:55,321 --> 00:02:00,462 the microkernel doesn't do much, it just passes requests along. 25 00:02:02,621 --> 00:02:05,720 For instance, if a server crashes, then that's fine. 26 00:02:07,080 --> 00:02:10,342 For instance a driver crashes, or just hangs, 27 00:02:10,342 --> 00:02:17,221 you just can kill and then pfinet will re-open a new instance of the driver 28 00:02:17,221 --> 00:02:24,041 and it will just work, thanks to TCP just continuing to ping the other computer. 29 00:02:25,261 --> 00:02:27,921 So it's just an error, it's not something of the death. 30 00:02:28,922 --> 00:02:33,041 At some point on my desktop, I could switch off the light, 31 00:02:33,041 --> 00:02:35,522 and then that would crash my laptop. 32 00:02:35,842 --> 00:02:42,940 Because switching off the light would reboot my hard disk, USB hard disk, 33 00:02:42,940 --> 00:02:46,461 and then the kernel of the laptop wouldn't like this. 34 00:02:47,421 --> 00:02:49,421 This is not something which is supposed to happen. 35 00:02:49,680 --> 00:02:54,401 So, with a server approach, this is completely fixed. 36 00:02:55,120 --> 00:03:00,321 It's also easier to debug, it's really nice to be able to gdb a TCP/IP stack, 37 00:03:00,321 --> 00:03:07,201 when there is something happening in there, just run gdb, you can gprof it, etc. 38 00:03:08,721 --> 00:03:10,780 You can also dare more crazy things. 39 00:03:11,102 --> 00:03:16,820 For instance, the Linux console doesn't support much, because we don't want to put 40 00:03:16,820 --> 00:03:19,120 too much complex code in there. 41 00:03:19,902 --> 00:03:23,881 On GNU/Hurd the console actually supports things like Chinese, 42 00:03:23,881 --> 00:03:25,661 double-width support, etc. 43 00:03:25,961 --> 00:03:27,861 which is not supported by the Linux console, 44 00:03:27,861 --> 00:03:31,380 and that's right because you don't want to put too crazy stuff. 45 00:03:32,160 --> 00:03:35,661 Here since it's just a userland program, then you're fine, 46 00:03:35,661 --> 00:03:41,361 and so we do have Chinese support in, actually, textmode in the Debian Installer. 47 00:03:44,542 --> 00:03:52,401 Just to show an example, so here I have ftpfs which uses the TCP/IP stack 48 00:03:52,401 --> 00:03:56,101 to actually mount a remote directory, 49 00:03:56,101 --> 00:04:03,321 and then I can use isofs to mount an ISO image which is inside that FTP server. 50 00:04:03,861 --> 00:04:09,682 And then I can just let cp copy a file from the ISO image which is on the server. 51 00:04:10,441 --> 00:04:17,141 So this translates that way, so I've done this command a long time ago, 52 00:04:17,141 --> 00:04:22,600 just to say that "ftp:" in my home directory is whatever FTP, 53 00:04:22,600 --> 00:04:29,962 and then I can take a "~/ftp:/etc." URL and give that to isofs 54 00:04:29,962 --> 00:04:33,401 and then mount that on my "mnt", 55 00:04:33,401 --> 00:04:38,381 and then I can just browse inside the ISO image, without having to download 56 00:04:38,381 --> 00:04:44,481 the whole ISO image, without having to ask root for this kind of things, etc. 57 00:04:45,480 --> 00:04:48,601 And I can also permanently store this in ext2fs. 58 00:04:49,201 --> 00:04:53,561 So just to give an example, I have a translator on my signature files, 59 00:04:53,561 --> 00:04:58,660 which just calls fortune, so when I "cat .signature" [demo], 60 00:04:58,660 --> 00:05:02,600 I get one signature or another, because each time I open the file, 61 00:05:02,600 --> 00:05:06,941 it's a new instance of fortune which is started. 62 00:05:07,602 --> 00:05:12,142 You can see that, indeed, this is stored in my signature file. 63 00:05:14,061 --> 00:05:15,280 So this is fun! 64 00:05:16,721 --> 00:05:22,741 Another example: as a user, I can start my own TCP/IP stack, 65 00:05:22,741 --> 00:05:27,000 tell it to use a virtual network interface, 66 00:05:27,000 --> 00:05:32,303 and then put the TCP/IP service on some node in my home, 67 00:05:32,303 --> 00:05:37,764 and then I can run openvpn to actually push and pull packets 68 00:05:37,764 --> 00:05:41,500 from that virtual interface, and build a VPN with somewhere else. 69 00:05:42,121 --> 00:05:49,301 And then I can remap the system, what is supposed to be the system TCP/IP stack 70 00:05:49,301 --> 00:05:51,141 into my own socket, 71 00:05:51,141 --> 00:05:58,441 and then I get a new shell for which the system TCP/IP stack is actually 72 00:05:58,441 --> 00:06:00,420 my own TCP/IP stack. 73 00:06:01,021 --> 00:06:06,382 So I can decide which program actually uses this TCP/IP stack, 74 00:06:06,382 --> 00:06:14,801 and just do my own VPN without having to ask anything to the administrator. 75 00:06:17,261 --> 00:06:22,361 But also, for instance it happens quite often that you have a binary, 76 00:06:22,361 --> 00:06:26,201 maybe not sh, but like, python or perl or whatever, 77 00:06:26,201 --> 00:06:34,301 you have a program which wants /bin/sh to be actually bash or whatever, 78 00:06:34,301 --> 00:06:38,841 so I want to change this, so I can remap this, so for instance [demo] 79 00:06:38,841 --> 00:06:43,541 if I look at sh, so as usual, oh it's green, 80 00:06:43,541 --> 00:06:45,541 but you can see here that it's dash, 81 00:06:45,541 --> 00:06:53,201 and if I remap /bin/sh into /bin/bash, for instance, I get a new shell where actually, 82 00:06:53,201 --> 00:07:01,661 sh is not the same, so it's remapped into /bin/bash, 83 00:07:01,661 --> 00:07:04,441 and so it's actually bash which actually shows up here. 84 00:07:04,860 --> 00:07:10,881 So I do really choose how I work, what my environment looks like. 85 00:07:11,921 --> 00:07:18,181 And for instance, I can remap the whole /bin directory into my own directory, 86 00:07:18,181 --> 00:07:21,581 where I expose /bin, but also other things, 87 00:07:21,581 --> 00:07:27,281 so that programs which have /bin/something hardcoded into them, 88 00:07:27,281 --> 00:07:32,381 I can use them without having to ask the administrator to install stuff inside /bin. 89 00:07:34,000 --> 00:07:41,040 So it's kind of interesting, a bit like stow, Nix, Guix, but done in a nice way. 90 00:07:43,321 --> 00:07:47,861 How does it work? Well it's actually relatively simple in the principle, 91 00:07:47,861 --> 00:07:52,021 it's simply that libc doesn't talk with the kernel or whatever, 92 00:07:52,021 --> 00:07:57,321 it always uses RPCs, so to ask nicely about opening files etc., 93 00:07:57,321 --> 00:08:04,021 and so it's really natural in GNU/Hurd that you can redirect things. 94 00:08:05,241 --> 00:08:10,840 So for instance, the remap translator here is like, maybe, 95 00:08:10,840 --> 00:08:13,481 200-300 lines [Note of transcriptor: 150 actually], 96 00:08:13,721 --> 00:08:15,320 because it's just a matter of 97 00:08:15,320 --> 00:08:20,161 "you open a file, OK, I look at the file path, is it something I want to translate? 98 00:08:20,161 --> 00:08:23,481 Yes, I translate that, and then I open the real file, 99 00:08:23,481 --> 00:08:26,641 and give the new handle to the program", 100 00:08:27,080 --> 00:08:29,401 and that's all, so it's extremely simple. 101 00:08:32,221 --> 00:08:36,940 So everything in GNU/Hurd is an RPC and so it is interposable, 102 00:08:36,940 --> 00:08:44,401 and then translators get exposed in the filesystem, we have seen the TCP/IP stack, 103 00:08:44,401 --> 00:08:46,961 it's just a path inside the filesystem. 104 00:08:47,721 --> 00:08:53,381 And then the user can decide whatever it wants to do to interpose whatever. 105 00:08:53,781 --> 00:08:58,981 So, for instance fakeroot, in Linux, is quite big, 106 00:08:58,981 --> 00:09:02,581 because it has to interpose libc symbols, 107 00:09:02,581 --> 00:09:07,401 and every time libc invents something new, then it breaks in fakeroot 108 00:09:07,401 --> 00:09:14,801 because fakeroot has to know about this new symbol, etc. and interpose them, 109 00:09:14,801 --> 00:09:18,221 either through ptrace or ld or whatever. 110 00:09:19,602 --> 00:09:22,641 In GNU/Hurd, fakeroot is, like, a thousand lines long, 111 00:09:22,641 --> 00:09:26,161 because it just implements a few basic things, 112 00:09:26,161 --> 00:09:34,861 and then everything just works, which just interpose basic authentication hooks, 113 00:09:34,861 --> 00:09:37,141 and libc uses them all the time. 114 00:09:38,860 --> 00:09:43,981 So it's fully virtualizable, and with a really fine grain interface, 115 00:09:43,981 --> 00:09:48,021 because you can precisely decide which RPCs are interposed, 116 00:09:48,181 --> 00:09:50,560 or which files in the filesystem are interposed. 117 00:09:51,821 --> 00:09:56,400 And then you can just use your home directory, the TCP/IP stack, 118 00:09:56,400 --> 00:09:59,981 and pile stuff over it, the way you want. 119 00:10:02,222 --> 00:10:06,321 Just to give a crazy example, we have a lot of stuff, 120 00:10:06,321 --> 00:10:12,201 I actually have an ISO image inside a partitioned disk image on FTP over a VPN. 121 00:10:13,041 --> 00:10:14,821 And this is not so crazy. 122 00:10:15,821 --> 00:10:20,282 Maybe the ISO image inside the partitioned disk, the ISO image is a bit too much, 123 00:10:20,282 --> 00:10:26,361 but one file inside the partitioned disk image on FTP over VPN is not so crazy, 124 00:10:26,361 --> 00:10:31,061 because maybe you are on a hostile network, so you have to use a VPN, 125 00:10:31,061 --> 00:10:34,761 and then you want to access a file you know is inside a disk image, 126 00:10:34,761 --> 00:10:40,441 I don't know, a known disk image which is provided on a public FTP server, 127 00:10:40,441 --> 00:10:44,001 and you don't want to download the whole image just to get, I don't know, 128 00:10:44,001 --> 00:10:45,502 the README file or something like this. 129 00:10:45,860 --> 00:10:49,481 So it's not so crazy, and it just works nicely. 130 00:10:52,141 --> 00:10:54,621 So a bit more Debian stuff. 131 00:10:55,601 --> 00:11:00,001 Porting packages to Hurd is quite easy in principle, 132 00:11:00,001 --> 00:11:05,520 because it's just a POSIX system, there is a lot more than just POSIX, 133 00:11:05,520 --> 00:11:07,521 but it provides a POSIX interface. 134 00:11:08,021 --> 00:11:11,761 So portable programs should be really fine. 135 00:11:13,121 --> 00:11:17,761 Just for fun, some dumb issues, so for instance some programs think that 136 00:11:17,761 --> 00:11:20,981 if it's not Linux or BSD, then they can include windows.h... 137 00:11:22,061 --> 00:11:22,881 Why not... 138 00:11:23,661 --> 00:11:26,241 If the system has mach.h, that must be MacOS, 139 00:11:26,561 --> 00:11:31,601 because MacOS is the only system in the world that uses Mach, I don't know why... 140 00:11:32,841 --> 00:11:37,861 Some people try to grep cpuinfo, which doesn't exist on GNU/Hurd yet, 141 00:11:37,861 --> 00:11:43,361 and so they basically just run "make -j" which just explodes the system, 142 00:11:43,361 --> 00:11:48,561 I mean even on a Linux system it's just the same, unless it's a small program, 143 00:11:48,561 --> 00:11:51,141 but with a lot of C++ files it's horrible. 144 00:11:52,302 --> 00:11:58,781 Some people include limits.h from linux/ instead of just the standard one, well... 145 00:12:00,741 --> 00:12:04,441 A problematic thing is people who hardcoded errno values; 146 00:12:04,441 --> 00:12:09,680 the values of errno are not standardized, so you shouldn't hardcode them, like, 147 00:12:09,680 --> 00:12:12,501 in testsuite results or things like this. 148 00:12:13,761 --> 00:12:17,561 And quite often in configure it's hardcoded that 149 00:12:17,561 --> 00:12:21,856 only Linux knows -lpthread or -ldl, etc. 150 00:12:22,061 --> 00:12:25,101 so quite often programs are not generic enough, 151 00:12:25,101 --> 00:12:30,061 and that's just easy to fix, but we have more and more of these. 152 00:12:30,641 --> 00:12:33,341 So we have a porter page developing a bit more about these. 153 00:12:34,581 --> 00:12:42,021 I wanted to talk a bit more about PATH_MAX, it is not defined on GNU/Hurd, 154 00:12:42,021 --> 00:12:46,560 for very good reasons, and it is allowed by POSIX not to define it, 155 00:12:46,560 --> 00:12:51,461 just to say that there is no limitation on the PATH_MAX value, 156 00:12:51,941 --> 00:12:54,261 we don't have a limit on the size of the paths. 157 00:12:54,922 --> 00:12:59,422 And indeed it has a fragile semantic, it has never meant 158 00:12:59,422 --> 00:13:03,881 "a reasonable size for an array of characters to store a path". 159 00:13:05,181 --> 00:13:09,281 On Linux it's 4000, that's a whole page, 160 00:13:09,281 --> 00:13:12,280 that's a whole TLB entry for just one file name. 161 00:13:13,441 --> 00:13:16,801 It's extremely costly, most people don't have so long paths, 162 00:13:16,801 --> 00:13:24,241 and so it's really a pity to use so much memory, because it's always a whole page 163 00:13:24,241 --> 00:13:27,421 because it will always be aligned on 4k etc. 164 00:13:27,941 --> 00:13:30,081 So, well, that's a waste for one. 165 00:13:30,701 --> 00:13:35,120 And paths can actually be longer, there is no strict limitation, 166 00:13:35,120 --> 00:13:40,062 you can mkdir something, cd into that mkdir again, cd, etc., 167 00:13:40,062 --> 00:13:43,501 you can do that as much as you want, there is no limitation on this, 168 00:13:43,501 --> 00:13:45,381 it's just that when you call 169 00:13:45,381 --> 00:13:50,841 "get current working directory", you won't get it completely. 170 00:13:51,761 --> 00:13:56,661 And actually, some programs misbehave in that case, 171 00:13:56,661 --> 00:14:01,421 because they won't see these files, they will be quite actually hidden, 172 00:14:01,421 --> 00:14:02,921 or protected, or I don't know, 173 00:14:02,921 --> 00:14:07,341 you can not remove them just giving the path, you have to cd, cd, cd, cd, 174 00:14:07,341 --> 00:14:08,820 and then you can access the file. 175 00:14:11,181 --> 00:14:15,242 And for no reason, actually, because Linux inside doesn't have 176 00:14:15,242 --> 00:14:17,842 such limitation, actually. 177 00:14:19,241 --> 00:14:24,821 And also, it's stupid, but POSIX didn't really said precisely whether 178 00:14:24,821 --> 00:14:30,060 the final \0 actually is included in PATH_MAX or not, 179 00:14:30,060 --> 00:14:33,521 so people would allocate PATH_MAX+1, or maybe not. 180 00:14:36,382 --> 00:14:40,660 So we have a lot of code which doesn't, maybe, actually work, 181 00:14:40,660 --> 00:14:45,121 but nobody tests it, actually, because they would never have so long paths. 182 00:14:45,741 --> 00:14:48,561 So I'm a bit afraid of all these codes using PATH_MAX. 183 00:14:49,541 --> 00:14:50,881 You should be afraid as well. 184 99:59:59,999 --> 99:59:59,999 Just to give an overview of the state. 185 99:59:59,999 --> 99:59:59,999 We have a i386 support, we have a 64bit support which has started, 186 99:59:59,999 --> 99:59:59,999 we have the kernel booting, 187 99:59:59,999 --> 99:59:59,999 and now it's mostly translating between 32 and 64 in our RPCs. 188 99:59:59,999 --> 99:59:59,999 We have drivers for network boards as a userland translator, using the DDE layer. 189 99:59:59,999 --> 99:59:59,999 We have disk, we have a Xen port. 190 99:59:59,999 --> 99:59:59,999 We have a preliminary sound which was announced today, using Rump, 191 99:59:59,999 --> 99:59:59,999 the Rump kernel. 192 99:59:59,999 --> 99:59:59,999 We don't have USB yet. 193 99:59:59,999 --> 99:59:59,999 It is quite stable, I haven't reinstalled my boxes for, like, a decade, 194 99:59:59,999 --> 99:59:59,999 I don't remember when I installed them, actually. 195 99:59:59,999 --> 99:59:59,999 And then the buildd machines just keep building packages for weeks 196 99:59:59,999 --> 99:59:59,999 without a problem. 197 99:59:59,999 --> 99:59:59,999 We have 81% of the archive. 198 99:59:59,999 --> 99:59:59,999 We have the native Debian Installer which is really working great. 199 99:59:59,999 --> 99:59:59,999 Recent work is, like, interesting thing is, a distributed mtab translator 200 99:59:59,999 --> 99:59:59,999 to provide /proc/mounts in a hurdish way. 201 99:59:59,999 --> 99:59:59,999 We have quite a few optimizations which went in to improve the performance. 202 99:59:59,999 --> 99:59:59,999 We had releases quite some time ago, 203 99:59:59,999 --> 99:59:59,999 I really recommend to have a look at this one, it's fun. 204 99:59:59,999 --> 99:59:59,999 We've some Wheezy and Jessie snapshots, 205 99:59:59,999 --> 99:59:59,999 they are not official, but for us it's really an official thing. 206 99:59:59,999 --> 99:59:59,999 An important thing I wanted to discuss this week is the removal from ftp-master. 207 99:59:59,999 --> 99:59:59,999 This is due since quite a few years now, honestly, 208 99:59:59,999 --> 99:59:59,999 it's really not useful to mirror the hurd packages over the whole world, 209 99:59:59,999 --> 99:59:59,999 because there are not even as many users as the number of mirrors. 210 99:59:59,999 --> 99:59:59,999 So OK, that's fine for just the removal from the main archive in terms of mirroring. 211 99:59:59,999 --> 99:59:59,999 But then we have a lot of consequences. 212 99:59:59,999 --> 99:59:59,999 For instance, buildd.debian.org is really an important thing, 213 99:59:59,999 --> 99:59:59,999 because that is where the release team schedules transitions, 214 99:59:59,999 --> 99:59:59,999 and loosing this, for us, would be really tedious work, 215 99:59:59,999 --> 99:59:59,999 because I've been there, doing, actually, the transition work, 216 99:59:59,999 --> 99:59:59,999 the same work as the release team, and it's really painful to do this again. 217 99:59:59,999 --> 99:59:59,999 So we would really like to have a solution for this. 218 99:59:59,999 --> 99:59:59,999 Maybe get that fed from debian-ports and, 219 99:59:59,999 --> 99:59:59,999 then that's fine, we can be on debian-ports, as long as at least 220 99:59:59,999 --> 99:59:59,999 there is some synchronization between something. 221 99:59:59,999 --> 99:59:59,999 And also, getting exposed on the buildd package status page, 222 99:59:59,999 --> 99:59:59,999 so that people are aware that there is some port which is failing, 223 99:59:59,999 --> 99:59:59,999 and maybe they are keen on spending some time on it, maybe not, 224 99:59:59,999 --> 99:59:59,999 but at least get them know about it. 225 99:59:59,999 --> 99:59:59,999 And also, a corner thing, when we have a version upgrade, like gcc or perl, 226 99:59:59,999 --> 99:59:59,999 the release team asks "OK, we'll have to upgrade the buildds", 227 99:59:59,999 --> 99:59:59,999 and at the moment they don't even have an account on them, 228 99:59:59,999 --> 99:59:59,999 so they can not check whether the version is good or not. 229 99:59:59,999 --> 99:59:59,999 Maybe we should just provide an account, 230 99:59:59,999 --> 99:59:59,999 we'd thus need to know who we need to give an account to. 231 99:59:59,999 --> 99:59:59,999 Basically, my idea would be "OK, that's fine not being on ftp-master". 232 99:59:59,999 --> 99:59:59,999 The thing is we still want to have most of the support of Debian, 233 99:59:59,999 --> 99:59:59,999 to make our life less a burden, as much as possible, 234 99:59:59,999 --> 99:59:59,999 without any extra load on the release team, etc. 235 99:59:59,999 --> 99:59:59,999 We do understand well that we don't want to put work on people's hand. 236 99:59:59,999 --> 99:59:59,999 But we would to still get some benefit and probably there are solutions for this. 237 99:59:59,999 --> 99:59:59,999 And conversely, all of this, I mean, not putting more work on us Hurd porters, 238 99:59:59,999 --> 99:59:59,999 would actually be the same solutions that existing ports on debian-ports 239 99:59:59,999 --> 99:59:59,999 would be really happy to have, to improve their life, to have less work to do, [...] 240 99:59:59,999 --> 99:59:59,999 So maybe we want to think about a real status for Second Class Citizens, 241 99:59:59,999 --> 99:59:59,999 like Hurd, but also the sparc, hppa, etc. 242 99:59:59,999 --> 99:59:59,999 Maybe want to have some BoF at some time, so we can gather and discuss about this. 243 99:59:59,999 --> 99:59:59,999 Future work, the most interesting thing is probably using the Rump drivers, 244 99:59:59,999 --> 99:59:59,999 because at the moment we use DDE but it's not really going forward. 245 99:59:59,999 --> 99:59:59,999 We thought it would be a way to get newer drivers, Linux drivers, 246 99:59:59,999 --> 99:59:59,999 without extra efforts, but it doesn't actually happen at the moment, 247 99:59:59,999 --> 99:59:59,999 while Rump does go forward, we see work being done with Xen etc. 248 99:59:59,999 --> 99:59:59,999 So this is probably a long-term solution. 249 99:59:59,999 --> 99:59:59,999 Maybe we'll have another distribution through Guix. 250 99:59:59,999 --> 99:59:59,999 This is progressing, we are quite far from doing this, 251 99:59:59,999 --> 99:59:59,999 so for now Debian is really the only Hurd distribution that we have, so we'll see. 252 99:59:59,999 --> 99:59:59,999 And of course, just come and have fun with your own pet project, just join, thanks! 253 99:59:59,999 --> 99:59:59,999 [Michael Banck] Any quick question before we run to lunch? 254 99:59:59,999 --> 99:59:59,999 [Steve Chamberlain] Hello, I just wondered 255 99:59:59,999 --> 99:59:59,999 if you're using Hurd on that laptop for the presentation? 256 99:59:59,999 --> 99:59:59,999 [Samuel Thibault] Yeah, yeah, this is running Hurd, yes. 257 99:59:59,999 --> 99:59:59,999 [SC] So it's quite, like, usable everyday? 258 99:59:59,999 --> 99:59:59,999 [ST] Well, not everyday because without USB, 259 99:59:59,999 --> 99:59:59,999 you can not mount a USB stick for instance, so that's quite inconvenient, 260 99:59:59,999 --> 99:59:59,999 but yeah, I could probably use it everyday. 261 99:59:59,999 --> 99:59:59,999 I don't, I mean, for work, I can not afford this, but yeah. 262 99:59:59,999 --> 99:59:59,999 Also, we don't have wireless drivers at the moment. 263 99:59:59,999 --> 99:59:59,999 We hope that with the Rump drivers we would get this. 264 99:59:59,999 --> 99:59:59,999 So, yes. 265 99:59:59,999 --> 99:59:59,999 Some people do use it everyday. 266 99:59:59,999 --> 99:59:59,999 Not me. 267 99:59:59,999 --> 99:59:59,999 [SC] But those would be the major thing missing for more people 268 99:59:59,999 --> 99:59:59,999 to be able to use it. 269 99:59:59,999 --> 99:59:59,999 OK, thanks. 270 99:59:59,999 --> 99:59:59,999 [MB] Any more questions? We're run out of questions, then thanks again. Thanks.
