Things to do in Sydney while the wireless is dead

Well, now that I’m back on the ‘net fairly reliably, I can post on what I’ve been doing for the past few days.

Firstly, I was off the Internet because I was flat-out busy on Saturday, in transit on Sunday, and wireless did not arrive at International House until about 11pm Monday night. That time I did spend on the ‘net today, at the conference, was spent in a combination of processing CBIT emails since Friday, and wrestling with my wireless network card.

My local build of the d80211 version of the bcm43xx driver got signal, would even get traffic through, but when it tried to reassociate to a different AP (all the APs here are running on channel 11… Although I was sitting next to someone who saw one on channel 1, which I’m guessing was rouge… I also saw some IBSS networks on the same SSID….) it would corrupt something nasty, kick the screen brightness up to full and oops with slab errors in short order.

The 2.6.18 (2.6.18-3-powerpc Debian build) bcm43xx softmac driver didn’t crash or anything, but generally performed worse, and when the Debian miniconf’s theatre (Mathews A) was full, my connection suffered or would completely fail to dhcp. >_<

On the plus side, the presentations were great. AJ gave us a rundown of debian-devel (ie 12 months of flamewars) and other significant Debian going-ons. Keith Packard produced a whole bunch of neat X things slated for X.org 7.3 (input hotplugging, dynamic output selection and modesetting, which is exactly what I need to get the projectors I keep plugging into to work better than 640×480…). Russell Coker talked about the various security gaps still remaining in Linux.

In non-conference goings on, I was talking to someone on IRC who’s gotten Second Life Viewer building under Linux/PowerPC (a previously unsupported platform) and I’m going to see if we can get a .deb built. I’ve already created an ELFIO package, and have the OpenJPEG source to try packaging tomorrow. I’ve also sent off an email to the person who ITP’d secondlife-client for Debian already, to see if he wants to co-operate, or if I’m just tooling about.

Speaking of tooling about, I decided it’d be a good idea to upgrade my bcm43xx-d80211 build to something more recent than mid December, but it seems the 2.6.20 workqueue changes mean I can’t compile it against 2.6.19 anymore. The rt2x00 d80211 stack has backwards compatibility macros for the workqueue stuff, but I don’t really feel like hacking those into bcm43xx, it’s already a large and unsteady beast.

BTW, cogito’s update could handle resuming better. Although it happily detected it was resuming a failed update, it had to keep refetching the packs. I eventually realised it would eventually time-out a fetch if I didn’t ^c it and happily try again, presuming I had in the meantime walked outside or reloaded the driver.

Anyway, so I’ve decided tonight (while I was still off the wireless) that I’d finally bite the bullet and build myself a custom dscape.git kernel, to see if the pain I keep suffering from the bcm43xx-d80211 driver is just my cheap-ass backport. That was still building when the wireless came up, and then barfed because KConfig happily let me include both the PCI and SoC versions of the OHCI USB host driver, which provide the same symbols. I must remember to file a bug report about that, or at least check linus’s git tree in case it’s already fixed. (Both drivers recommended yes, but are patently incompatible as they require different endianness of the host interface). I’ve restarted the make-kpkg, hopefully that’ll build overnight and I can try it in the morning.

I also put some time into my Remembering the Kanji book. I was going to do an hour, but after about a half-hour (with a break to configure and fire the kernel build off) I was yawning, and figured I’d prolly left the imaginative-memory zone. I was going to watch some Gokusen but thought I’d take a last wander over to the IH whiteboard to see if the wireless was up. Bizarrely, it was.

So I wandered onto the ‘net, checked email, volunteered myself to package Thousand Parsec for Debian, added the Kanji I studied to Reviewing the Kanji (a web site for reviewing the stuff you learn in Remembering the Kanji) and updated my blog.

Which funnily enough, is where we came in
