Five Minutes

A number of people have asked, so I shall state for the record that I’m not dead. Nevertheless, I’m extremely grateful to everyone for the concern shown for me after I was taken ill yesterday, and particularly to the guys — Andrew and Brian (I think; if I’ve gotten your name wrong come find me during the conference and smack me, just not in the head) — who came with me to the hospital.

Fortunately, today’s been a much better day. Since I’d already spent the money on a ticket, I decided to go to the Big Day Out for a little while this afternoon. I got there just in time to see Regurgitator and left after seeing Arcade Fire, not wanting to push my luck too far. It’s the first time I’ve seen Arcade Fire live, and it was everything I could have hoped for and more. Against that, Flemington Racecourse was warm, very dusty, and almost totally devoid of shade. I’ll just make sure I’m back in Perth for the Claremont Showgrounds show next year.

Tomorrow: Miniconfs! No idea which one I’m going to yet, but it should be fun anyway.

My bank balance has worn one — actually, several — for the team, but I’ve finished a very productive day arranging the various bits of travel that I have planned for this summer. In order, I shall be inflicting myself on gracing the following cities with my presence:

• Brisbane (and any parts of Queensland I can get to during the five days I’m hitting the road that aren’t infested with schoolies): November 20 to 30, ostensibly to attend OSDC. Also the Muse concert on the 21st. I’m still not sure which one I consider more important.
• Shanghai: December 5 to 20, for a university study trip. I also have about 24 hours in Singapore (which I’ve never been to — well, outside the airport, anyway) on the way back, so if the lazyweb has any suggestions for things to do there which could be fitted into, say, a morning, I’d love to hear them.
• Mel8ourne: January 27 to February 3. I note that an open day has been scheduled for my birthday. How good of the LCA organisers to give me such a nice present.

Simplistic maths suggests that I’m going to be out of Perth for ~45% of the time between November 20 and February 3. Sounds like a summer of fun to me!

For some reason I still can’t quite fathom, people have been interested in my Hackfest entry at LCA. Specifically, the entry I put in for the Audioscrobbler question, which asked us to create a program that could interface with the Audioscrobber related artists API. I decided to write a buzzword compliant Web page. So, I’ve uploaded it to http://www.adamharvey.name/hackfest/ for your viewing pleasure. You’ll need a browser with decent XHTML and SVG support. Firefox 2 seems to handle it nicely.

It uses PHP 5 for the little bit of backend processing it requires, but most of the heavy lifting is in Javascript. The only other dependency is the HTML_AJAX PEAR package — I developed against a test release of 0.5.1, but 0.5.0 should work as well.

The files I actually wrote (be warned, they’re messy and undocumented):

• index.php: The entry point for the user. It’s only in PHP so I can control the Content-Type header.
• server.php: The AJAX server which pulls in the Audioscrobber related artists information.
• audio.js: The Javascript that does the heavy lifting of getting the related artists information and spitting out SVG via the DOM to render it.

You can consider these files to be licensed under either the GPL (which was a condition of entering Hackfest) or the MIT License. HTML_AJAX is licensed under the LGPL.

I had the best of intentions when it came to blogging LCA, but it’s easy to forget just how all-consuming it can be. (I haven’t read a newspaper for a week, either.) So, instead of making up for it with a deathly dull four page blow-by-blow account, I’ll just jot down a few feelings now that I’m back in Perth and then stop breaking Planet LCA once and for all.

I thought the programme this year was outstanding. Every talk I attended rocked in some way, whether from the point of view of cool hackery (Nouveau), usefulness (Eat My Data), or sometimes sheer chaotic entertainment (x86 Hypervisors). HackFest was also really, really good fun, and I ended up with a completely unexpected little toy to bring home, pictured below. (The LCA 2006 key ring/bottle opener is for scale.) Congratulations to Stephen Thorne, too, who really, really deserved to win after attempting five more of the problems than I did.

Plus, even Tux finds HackFest cool enough to attend!

Otherwise, the experience is really the key. While I could go a long time without hearing Good morning, freedom lovers! again, LCA’s such an insane, overwhelming experience that you can never really get much more than a taste. As with every other year, though, I’ve found myself coming home with lots of things to try, lots of things to work on, some new people to annoy talk to on IRC — and, ultimately, just having learned more in a week than I would have in 51 weeks at the office through attending talks and talking to people who are way, way smarter than I am.

Now I just have to look forward to Mel8ourne — only 373 days to go!

Random images from Shalom College tonight. People say the Internet and pervasive wireless will isolate people in their rooms — these images suggest that less-than-pervasive wireless will actually bring people together.

The link between the old and new parts of Shalom’s first floor.

The very popular couch area at the top of Shalom’s main staircase… now with wireless behind the bin!

The main common room in Shalom. Note the various groups of people interacting in ways other than IRC. (Yes, really.)

More people in the common room.

So, as you can see, LCA once again brings people together from across the hacking world into university accommodation. It’s like a slightly geeky “Big Brother” without cameras. That we know of.

Finally, I give you Steve without his super wireless powers:

First, Shalom wireless news: we now have coverage of the first floor common room (which is next to the dining room, for those who haven’t quite figured out the building layout yet) and the couches at the top of the stairs. The Internet is spotty and not especially quick, but it does work. Massive thanks to John Ferlito, Ian Beardslee, Steve Walsh, Andy Kirkpatrick and the people whose names I didn’t catch but who helped while getting our insanely hackish wireless network happening, particularly Ian’s friend with the OpenWRT-fu.

In non-Shalom-wireless news, there was a party tonight. It was good, since it involves an open bar and free swag. Of course, said bar and swag led to… the Linux ninja!

Moving right along, the bar tab partway through the night can be seen below. I feel sorry for whomever’s Google corporate credit card is being used.

Still, I think everyone had a good time. Much networking (of the social variety) took place, which is always excellent. The dancing, however…

Anyway, in other news, the PostgreSQL talks I went to today (the ones before and after lunch) were terrific. I think you would have learned something from those sessions pretty much regardless of your experience with Postgres, which is the sign of a really good talk. Kudos to the organisers in general for shuffling the rooms allocated to each talk around after lunch, too — the Postgres talk, for one, really benefitted from the larger room.

Before I go to bed, a question. Can anyone explain how the fan seen below, which is in one of the Shalom common areas, is supposed to work? Note the length of the power cable attached to it and the location of the power point.

Truly, a mystery for the ages.

Just ran into some orange shirted guys while warwalking around Shalom. Basically, the deal with wireless at present is this: if you are immediately around room 113 (or 213, or maybe G13), chances are you can access wireless. If you are anywhere else, chances are you cannot. Unfortunately, this doesn’t encompass any common areas except for maybe the first floor pool room — it didn’t work for me, but if you have a good wireless chipset or coathanger antenna or something, you might have more luck.

As I understand it, there’s just no way to get LCA network infrastructure into anywhere more useful in Shalom, and after talking to them, they (for understandable reasons) won’t let us run a cat 5 cable down to the first floor common room or somewhere equally useful. Therefore, it looks like we may be, as the technical term goes, SOL.

As further proof that God exists and His name is Steve Walsh, I present the following images documenting how the Frankenet providing Internet access to the Shalom common room…

The overall setup. Note the iBurst card on the laptop at left.

The iBurst card in close-up. I think Steve’s very thankful he doesn’t pay per megabyte at the moment.

GKrellM on the laptop, showing the Internet usage — which, given it’s shaped to 64 kBps, is pretty hefty.

Courtesy of the organisers and the persistent Steve Walsh, we now have some wireless access for the evening in the first floor common room in Shalom College. Apparently something more permanent will be in place later, but for now, it’s working.

Day one of LCA 2007. Went to Jeff’s tremendously entertaining conference opening, dealt with a server at work that managed to fall over while Adam and I were still on the plane yesterday, and finally decided that I could skip a few sessions and check out Sydney City.

Of course, what that really means is that I went to Circular Quay, went over the Harbour Bridge, got a ferry across the harbour, walked around the Opera House, and got incredibly cheesed off at the price of going up Sydney Tower. I think that gives me the authentic Sydney tourist experience in three hours flat.

Now back at the Pavillion sucking up some sweet, sweet wireless. There was talk on the Shalom whiteboard of there being a New Zealanders dinner (with us West Islanders invited too), but I think it’ll end up just being a quiet dinner at one of the restaurants on Anzac Parade and an early night, because let’s face it, there’s not going to be too many more from here.

Tomorrow: Chris Blizzard, Jokosher and tonnes of Postgres.
