linux.conf.au 2007: Monday 15th Jan

The best thing about linux.conf.au so far was yesterday’s weather. It was mild with a slight breeze, and the venue has made the mode of it by using UNSW’s glass-walled Pavilion near the Clancy theatre for hack and chat space. (As with OSDC though, people can’t tell the difference between someone noodling on their laptop and someone doing work, and interrupt both sorts.)

Jeff gave the conference opening talk and forgot to introduce himself. It was a fun talk. About a week ago he called me to ask what he should say about the lca Woman Triumph. Over 10% of registrations were women, which doesn’t sound much until I remember that at linux.conf.au 2004 there were eight women — not eight percent, eight. I actually advised him not to dwell on behaviour too much; lest the men be insulted and the women think that they’d accidently signed up for Barbarian Finishing School (how to talk to girls, level 1). He did stick a don’t be creepy on the end of that section, with the result being that a couple of guys came up to me and joked about how they could be creepy but weren’t allowed to.

Guys: creepy is creepy, but meta-creepy is both stupid and irritating. Don’t do either of them, and don’t start on the meta-meta, thank you.

The first two days of the programme, yesterday and today, are mini-conferences (think workshops), organised by communities like Debian or GNOME, or by interest groups, like people interested in education. I am running a LinuxChix one today. The conference has decided to embrace them this year: rather than describing them as a sort of a pre-conference bonus, the mini-conference schedules went into the main schedule, and Chris Blizzard’s keynote is scheduled this morning to lure people to the mini-conferences afterwards.

Yesterday this seemed to be a bit of a mixed blessing, because the mini-conference organisation and programmes largely aren’t up to the standard of the main conference, which has a programme I just can’t stop drooling over. Two things! In every session! That I want to attend!

Andrew said yesterday that he should have stretched a bit and gone to the embedded miniconf rather than GNOME, and I sort of agree for myself too. I tried Education in the morning, but Pia had had to move her talk at the last minute, and in fact backed out of her slot later in the day too, leaving their programme in disarray for the casual attendee, because every session they’d announce a random talk.

I went to the GNOME talk on Avahi, which just didn’t grab me somehow, and then Jeff’s talk, entitled Connecting the dots, in which he mostly demonstrated the capabilities of his Wii. Now, actually this was kind of interesting for me, because Andrew and I didn’t set up our Wii until last night, so we’d never seen it in action. And James, who is well out of console-land, was fascinated. But by the conference’s core criteria — talk about Free Software, or Free Culture — it was a complete disaster, since the Wii while cute, is extremely proprietry.

Since I had my own mini-conference today to prepare for, I didn’t attend any more sessions after session 3 yesterday. Instead I sat in the nice open air pavilions and worked on slides, and then Andrew and I took off for a yoga class in the evening and went out to dinner afterwards.

Links to Women in Free Software groups

I gave a 5 minute lightning talk at OSDC entitled Women in FOSS groups (meaning groups for women involved in Free Software, rather than about women in Free Software groups, I could have done a better title I know). It was mostly an attempt to jam Adam Kennedy’s lightning talk about Acme::Playmate, which featured lingerie shots of women (and maybe topless shots, I didn’t want to watch it, being quite firmly and viscerally of the belief that there’s a very small amount of sexual desire I like at my open source conferences). So mine featured pictures of women, fully clothed, with labels like Linux user and AI researcher.

For more on Kennedy’s talk, see Richard Jones’ entry about it: Jones was the chair of the session that Kennedy gave his talk in.

I’m not putting my slides up for a few reasons: bits of them only make sense in the context of that particular jam; other bits only make sense if you hear me say the words that went along with them; and finally while I got permission to use them in the talk, I didn’t get permission from all the women whose pictures I used to stick said pictures on the ‘net.

However, the last couple of slides were a list of links to groups for women using and developing Free Software, and Paul asked if I could provide them in a place where people would have a chance to write them down. Fortunately, these were even prepared earlier:

  1. LinuxChix’s list of groups for women in computing generally; and
  2. LinuxChix’s list of groups for women developing Free Software (and Free Culture, in the case of WikiChix).

My talk at OSDC: the Planet Feed Reader

I gave a thirty minute presentation at the Open Source Developers’ Conference yesterday about the Planet software and the associated communities and conventions, focusing more on the latter since one of my reviewers suggested that the social aspects are more interesting than the code. My slides [PDF format, 2.1MB] are now available for the amusement of the wider public.

Much of the discussion of history was a recap of my Planet Free Software essay and the discussion of Planet conventions was a loose recap of accumulated wisdom, including:

  1. using bloggers’ real names, or at least the ones which they attach to email (usually real names) in addition to common IRC/IM handles is useful for putting faces to blog entries to contributions;
  2. once the convention of using real faces and real names is established, people get upset when the conventions are broken (quoth Luis Villa: I’m not sure who/what this ubuntu-demon is, but ‘random animated head without a name meandering about doing a lot of engineering work to fix a problem that should not exist’ was not what I was looking for when I was looking for information on planet ubuntu); and
  3. life blogging is of interest to an extent, many developers would actually like to feel that they’re friends with each other, but the John Fleck case on Planet GNOME shows that there are limits.

Much of the rest was due to Luis Villa’s essay on blogging in the corporate open source context, but as I wasn’t allowed to set assigned reading to the audience I was able to pad out by half an hour by including that content.

Mostly it was a fun experiment in doing slides in a format other than six bullet points per slide, six slides per section, six sections per talk format; incorporating badly rescaled images in various places; and using Beamer so I was surprised to end up hosting a Planet BoF (Birds of a Feather) session, discussing it from the point of view of someone running a Planet (the editor). Some of the topics that came up were:

  • trying to start communities via Planet sites, rather than enhancing them, by, say, starting a environmental politics Planet;
  • the possibility of introducing some of the newer blog ideas to the Free Software world (like carnivals);
  • allowing a community to edit a Planet, and editorial policies in general;
  • potential problems with aggregating libellous or illegal content (another reason some editors apparently insist on real names);
  • alternative aggregators;
  • banning RSS in favour of Atom;
  • whether it is possible or wise to filter people’s feeds without their consent;
  • moving to the Venus branch of Planet; and
  • making Venus trunk.

I may propose a blogging BoF at linux.conf.au and, if I do so, I’ll even plan some discussion points, which will make it less random.

Logging into the OSDC wireless network

I have a wireless login script for attendees of OSDC who use Ubuntu, Debian, or anything else that can run scripts on connecting to a network and has essentially the same iwconfig output:

 eth1      IEEE 802.11g  ESSID:"Monash-Conference-Net" Mode:Managed  Frequency:2.437 GHz  Access Point: 00:13:7F:9D:36:C0 

To save some tiny amount of time when connecting to the wireless, stick my osdc-login script in your /etc/network/if-up.d directory or equivalent and give it similar permissions to what’s already in there. You can get the latest version of the script at https://gitlab.com/puzzlement/osdc-2006-monash-wireless-login/raw/master/osdc-login, or through Bazaar git, with the repository at https://gitlab.com/puzzlement/osdc-2006-monash-wireless-login/tree/master. It’s very small, but feel free to send me improvements (although if using Bazaar git, please don’t check in a version containing the real username and password).

You need to replace INSERTCONFERENCELOGINHERE with the appropriate username and INSERTCONFERENCEPWHERE with the password. By running the script you will be agreeing to Monash’s terms of service, which are here.

linux.conf.au payments (attention earlybirds)

Just spreading the word, since neither Andrew nor I received an email invoice for our registration: credit card payments for linux.conf.au are now being accepted. (We did get the announcement, but previous conference experience—ACL, HCSNet—this year has unfortunately taught me that registration information is not sent out using titles like Countdown to linux.conf.au 2007: 48 DAYS TO GO, those kind of titles now indicate to me we’ve updated the website! and now we have a directory of attendees!, ie, not action items. So, I didn’t actually read it. Oops.)

People who got the earlybird price (which closed Nov 15) must pay by December 8. You can also still register now and get the regular price, although as the announcement (also) pointed out, if you want to stay on campus in the pre-arranged accommodation, or you want to go to the dinner, register soon. (It’s unpredictable how full they really are, until they start re-opening spots that people haven’t paid for. But 450 attendees who haven’t put down money yet is still a goodly number when I believe the aim is 800.)

In Melbourne Dec 5–10

Dear universe, Andrew and I are in Melbourne for OSDC from Tuesday December 5 to Sunday December 10 (in the morning, anyway). If any of you are in Melbourne that week and would like to meet us for breakfast/lunch/dinner/drinkies, get in touch.

Ubuntu code names

A relatively idle thought after doing Ubuntu support on LinuxChix lists for a while: are the code names really such a good idea? People have an enormous amount of trouble correctly identifying their Ubuntu version. I’ve seen the following problems:

  1. people not realising that the zeros are significant in the version number and asking for support with Ubuntu 6.1 (they probably mean 6.10/Edgy Eft) or 6.6 (they probably mean 6.06 LTS/Dapper Drake);
  2. at least half the time people quoting the Ubuntu version number and codename together quote a mismatched name and number (Ubuntu Breezy 6.06, Ubuntu Dapper 6.10 and that’s not even getting into Ubuntu Breezy 6.1 or Ubontoo/Urbanto/Obonto Dragon and so on), which means that you have no idea which version they actually mean; and
  3. the code names are memorable, but seemingly not memorable enough, there’s a lot of people out there talking about the Edgy Elf, which sounds like a bad drug pusher.

Ubuntu is far from the only software using well publicised release code names. I remember the good old days pre-Windows 95 (the good old days are always more than a decade ago), when you couldn’t talk computers without talking about ‘Chicago’. Debian’s release code names are also very commonly used; potato, woody, sarge, how well I remember thee, and I have no idea what thy version numbers were. In fact, the problem might perhaps be that the release code names and the version numbers are essentially equally well known when it comes to Ubuntu, so people feel the need to state both and aren’t clear on the mapping between them.

I suspect also the regular releases are hard on people: people know that there’s lots of Ubuntus and they have to identify their one, but there’s changes often enough that casual onlookers and users are more confused by the release names than they are aided by them. The release numbers map to the release date (4.10 was released in October—month 10—of 2004, 5.04 in April 2005 and so on) but most people, I believe, treat version numbers as Marketing Magic the like of which mortals do not ken and question no further. The six month release cycle means that the current system always has several easily confused releases too (you can confuse either the first number, mixing up 5.04 with 5.10, say, or the second one, mixing up 5.10 with 6.10).

I don’t have any particular suggestion about an alternative, and suspect that the developer community is wedded to their names even if the users are a bit puzzled. I suppose simpler would be better: Ubuntu 1, Ubuntu 2… but then the numbers get high quickly.

Really final evaluation of edgy

Really final, because last time I hadn’t upgraded a server, and yesterday I did. It made me very sad indeed.

Original complaint Bug number Fixed? Remaining sadness level
apt crashes when upgrading courier-authlib 64615 No (there are a couple of potluck workarounds in the report) High, because it took me about an hour and a half to hunt down the bug report and get apt and dpkg to dig themselves out of the mess they were in.
Transparent proxying in Squid is broken 68818 No (there’s a fix and workaround in the upstream report) High, because it took Andrew about an hour to hunt down the bug report and jigger with the upstream workaround. Yes I know transparent proxying is evil, and someday someone will figure out a clean way to autodistribute proxy settings whenever I connect my laptop to a new network, but until then I use it.
Network Manager can’t always tell the difference between wired and wireless cards 59981 Yes Moderate, fixing this one has just made the intermittant appearances of 40125 more obvious, but somehow I find 40125 less irritiating.
Nevow is completely useless, won’t even import properly in Python 61423

No Moderate. It turns out (and by it turns out I mean I figured out) you can install the Nevow 0.9 package from Debian unstable and it will work just great. But if Nevow isn’t supported even to the point of shipping an importable Python package, why is it still in Ubuntu’s main? This enhances my sadness level.
If you type words into the address bar, the epiphany browser no longer treats them as search terms for Google, it instead treats them as a bad URL. 56610 No (patch is available) Low, since I was able to build the fixed package as suggested in the report.
When I attach my Canon IXUS 65 to my computer via USB, Import Photos reports Could not claim the IO device. 64146 Yes, or at least they say so and it works for me, but people are still adding to the bug. Low, and only because I keep getting the bug mail about it.
X can’t always… work [actually, probably a bug in vbetool, causing rendering glitches on resume from suspend] 60882 Officially no, but I see it occur way less often now, maybe not at all since Edgy released. Low, since I see it so seldom. It’s really annoying when it does pop up though.
Aptitude… is now incredibly slow to resolve dependencies 51893 Yes None
GNOME reports that CPU scaling is not available on my machine Wasn’t one, I didn’t have powernowd installed N/A None
