The /System/Aliens talk from the Distro Summit is still missing in action. I’m not sure whether it’s coming or not, but it’s looking unlikely at this point.

More releases, all bugfixes this time.
Scripts has a fix for the man directory path in PrepareProgram (actually used by Compile), and handles dependency conversion better. It also includes updates to the database used by the CommandNotFound system as usual.
The only notable behaviour change is a special case in the useflag code: having -INSTALLED in the environment variable will now disable automatic flags from occurring at all, rather than applying the change at the end of the process. This helps debugging of recipes and is useful for targeted compilation, and the previous more consistent behaviour doesn’t seem to have a use case.
Compile has a single direct bugfix, affecting a case where a failed direct dependency would not cause the build process to terminate. It also benefits from the changes made within Scripts.
The packages are on the master now and will propagate to the mirrors shortly. You can use `InstallPackage Scripts 2.10.2` and `InstallPackage Compile 1.13.3` to install them. Please report any bugs you encounter in the bug tracker and request help either on the mailing lists or the forums.
Thanks to all those who contributed to this release, particularly “Baffo32″ who sent patches to Scripts.
There’s a new version of Compile out, with all bug fixes this time. This release fixes building from CMake recipes and corrects the behaviour of the using_X() useflag functions, which was lost in the last reorganisation. using_X() can now set environment variables and override variables set in the recipe again, while CMake recipes have their build directory correctly created.
The package is out and making its way to the mirrors now; InstallPackage Compile 1.13.2 should pick it up. There is no corresponding release of Scripts this time around because all fixes are within Compile itself. The latest Scripts release remains 2.10.1.
Following this release the 015 branches for Scripts and Compile will be merged into trunk to allow them to bed in, get more testing, and pick up the new developments in the trunk. That may cause some disruption to users who are tracking trunk tools; it may be best to hold off updating your snapshots for a few days after the merge, or be prepared to revert.
There is also a new 015 prerelease available for testing, snapshotting the state of work right now. It is available from http://karlsson.sytes.net/gobo/015/iso/GoboLinux-20100214.iso and should be functional. Testing, especially on different hardware, would be appreciated. It should boot and be able to start X correctly; where it doesn’t please make a report with as much detail as possible to the mailing list or on #gobolinux.
The last day brought the reason I was really there, my GoboLinux presentation in the very last speaking slot. Before then I made it into Sarah Sharp’s USB 3 talk, the photo management BOF, which was less useful than anticipated, and Rusty’s Wiimote presentation. The latter was both amazing and adorable, and well worth watching when the videos come out. The video of the first time it actually worked left me open-mouthed from both directions. That was the last talk I got to since I spent the next couple of hours preparing and practicing.
My slot was right before the closing ceremony and not too badly populated given that it was against at least two others I wanted to see. I don’t think it went too badly, though I did fixate on minor topics at a couple of points, and there were some good questions at the end. Since we were before the ceremony the cutoff was rigorously enforced and we actually ran out of time for them all, but I did have a chat with a couple of interested people at the stage while I was packing up.
Interestingly, and unexpectedly, an article turned up on TechWorld the next day about my talk and about GoboLinux. Some of the quoting is interesting, but the gist of it is there. The slides are also available (I think they’ll be on the conference site too at some point; at least they were collected on a USB stick afterwards), as is a more formally written-up version of the presentation. It doesn’t have all the content the talk did, since I added a few parts, including the whole Rootless section, in the aftermath of Monday’s Distro Summit discussion. Video should be available in a couple of weeks.
The closing ceremony was good enough, but ran long (and started late, so we didn’t really need to have rushed the questions so much…). Mostly that was to fit in thanks to the organisers and helpers, who really did do a fantastic job, so no complaints. Next year’s conference is in Brisbane. I’m not sure whether I’ll go or not yet, but it was definitely valuable this time so I will consider it. No speaking maybe ever again though. The Penguin Dinner that night was all right but also lagged a bit. The entertaining part of it was the Life Flight Trust donations race, which had a fivefold increase in the donation volume in just a couple of hours. I left early to get some actual sleep, so I’m not sure how high it got by the end, but it was approaching $20,000 last I saw.
I was hoping to find out the total at the open day today, but it didn’t appear to be up anywhere. I did get a lot of brochures and blurbs instead, and there was free stuff everywhere too. I didn’t end up with much of that; it was probably more appreciated by my later companion, who got all klepto (but not as klepto as she wanted to be, which seemed like a wasted opportunity). Most appreciated was the koala pen from the LCA2011 booth, so good marketing on their part. It was cute.
That’s a wrap. Later I’ll write up something on the various community engagement presentations I attended, which I think we can get some value out of. There were some others I didn’t make it into that I’ll watch when the videos become available. Right now I’m appreciating the opportunity to do something non-conference-related for a while.
I made my first presentation at linux.conf.au today, in the Distro Summit miniconf. I talked about the Aliens system, and it wasn’t a disaster, which is a plus. It went reasonably well, though I missed out on a couple of points I was planning to hit since I went off-script a bit. All the important content made it in, and there were plenty of good questions afterwards (& during). The speaker immediately after me had travel problems and didn’t make it, so there was an extended discussion jumping off from my talk that I think covered a lot of useful territory. It was a good miniconf to be at.
I appreciated the copious power points around to keep the battery charged, and the wireless network I managed to get working today (except in the Civic Suite where the miniconf was, annoyingly [edit: and they’ve fixed it! Amazing.]). Kudos to the organisers. The tech people from the conference were also fantastic helping me get the projection up and running, even though it was completely my fault it wasn’t working. He was, in fact, a genius full of information, like he said, so people got to see my fairly information-free slides. Thankfully I’d turned up early to make sure it was going to work.
Those slides are available now, as is a written-up version of it that has more content than I was able to fit into the talk. I had to go through it with a hatchet last night and today to make it fit in the twenty-minute slot and some good parts had to go. Honesty dictated that I couldn’t leave out any of the limitations and drawbacks so it was mostly the rest that got the chop. The main talk is on Friday, and there were a few points that came out of the discussion today that I’ll work into it as well. It turns out everything is being webcast live, which I didn’t find out until after I spoke today, but you can watch Friday’s if you like (Renouf 1 feed, 1545L/0245Z). There’ll be recordings up too, apparently later in the week, which’d be an impressive feat, but at some point over the next few weeks or months anyway.
Now I have to try to plan out what I’m going to go to tomorrow. It’s not going to be easy.
The conference is the week after next, and I will be presenting twice: once on the Monday and once on the Friday. On Monday in the Distro Summit miniconf I am speaking on the somewhat opaque topic of “Integrating domain-specific package managers into distribution package management systems”. That’s /System/Aliens, or trying to tie systems like CPAN, RubyGems, LuaRocks, and an ever-increasing number of others into the distribution package manager in order to avoid user conflicts and get automatic access to the full repository of their software. I seem to be just about the only speaker there who isn’t from Debian, so I’m not sure how that’s going to go down. My talk is at 13.30 in Civic Suite 3 inside the Town Hall.
In the main conference on Friday, in the very last presentation slot, I will be speaking on “An updated directory hierarchy for Unix”. That’s a broader GoboLinux paper where I will talk about the hierarchy we’ve chosen and discuss a little of the history behind the standard structure, particularly why we feel it’s ok to break with it. I’ll be talking about the advantages the new structure brings for the administrator, including some of the lesser-known traits that fall naturally out of it, and a couple of other (not so hierarchy-related, but interesting) features that we have. That part will probably include a brief discussion of Aliens too, looking at it from more of a user perspective than the implementor’s view in the miniconf. I’ll also try to dispel a few of the more common misconceptions we run into, but that may be a bit much to hope for. That presentation is at 15.45 Friday in Renouf Foyer 1 in the MFC.
At least the second talk should be recorded and the video available afterwards (for the miniconfs it’s “best effort”, and there’s bound to be a few kinks on the very first day). There will also be more comprehensive written papers available here afterwards, particularly for the Aliens system. I’ve tried to document it as fully as possible in the written version, while the twenty-minute talk has a lot of the less-important details left out. That one’s going to be cutting it a bit fine as it is, and I may need to trim more still to make sure there’s time for questions. If there’s anything important cut I’ll work it into the other paper to make sure we get it out somewhere. It’s been suggested there might be room for a lightning talk during the open day on Saturday too, but I’m not sure whether I’ll be talked out by that point, so we’ll see how it goes.
Registrations for the conference have been extended so there’s still an opportunity for anybody to come along and watch me if they want. There are a lot of other presentations as well that look more interesting still, so it should be an enlightening week.
