Minor annoyances [Mar. 10th, 2008|08:47 pm]
[Tags|, , , , , , , ]

A guy on Reddit pointed me at this article today. It's the Wikipedia biography of the Welsh computer scientist Donald Davies. Like my father, he was from the Rhondda Valley; he was the co-inventor of packet-switched networks (like this big one you're using right now); and he once found a bug in Alan Turing's code, before the first computer had been built :-)

I think he may be my new hero.

In other news:
  • I've just finished Portal. It was great, but far too short :-( If you haven't played it yet, then you should go and buy/download a copy right now, and cover your ears and sing "La la la la la..." until it's loaded to avoid being spoilered like I was. The puzzles are still a lot of fun, but the plot and jokes would have been a lot better if I hadn't half-known they were coming.
    [And I didn't find "The Cake is a Lie!", even though I was looking out for it...]
  • Spent a lot of time sitting at the computer today, but didn't get any thesis done. Bah.
  • After a similarly unproductive morning yesterday, I went to the climbing wall, and had quite a good session: I did two 6as (which is good, for me), led a widely-agreed-to-be-undergraded 5+, and finally knocked off a 5+ with a big scary overhang that had been tormenting me for months. Yay!
  • This may be the most awe-inspiring programming war story I've ever read.
  • Letter from Linacre: I didn't get the job. Never mind.
  • The winter mountaineering course I was booked on next weekend has been cancelled due to lack of interest. Just when the snow's started up again! I'm much more annoyed about that than about the rest, to be honest.

Ah well, tomorrow will be better. Anyway, have a look at this video, which is the trailer for one of the films I saw at the mountain film festival on Saturday:



That sea arch he's climbing up the underside of, by the way, is provisionally graded as a French 9b :-)

Random life update [Mar. 3rd, 2008|10:48 am]
[Tags|, , , , , , , ]

  • My supervisor, who's been away in Barcelona for the last month, dropped in for a flying visit last weekend. We had two mammoth three-hour meetings in two days, which was excellent in that I now have lots of stuff to work on and some idea of how to fix up things that were broken, but utterly knackering. Momentum has been lost a bit (hence the Fine Structure stuff). Thesis currently stands at 64 pages.

  • My office-mate Martin's stag night was on Saturday, which was good fun. It was the first stag night that almost all of us had been on, and it was fairly quiet - pub meal, trip to off-license to stock up for later, second pub, burger van, back to Gareth's flat for Wii games and more beer, argument with the jobsworth in the McDonald's drive-through who refused to serve us on the grounds that we weren't in a car, more Wii, decide at about 3am that I'm tired and should go home when I finish this drink, sit back in comfy sofa, look at watch again, discover to my horror that it's now 5.30am. One guy seemed determined to serve as our personal Bad Idea Bear, and kept making suggestions like "Let's play a drinking game!", or "let's all order drinks with stupid names!", or "let's get flaming sambucas!". The rest of us mostly kept him in check, though.

    My trouble is that I drink quickly - not just alcohol, any liquid - so even if I alternate alcohol and water I still take in quite a lot over the course of a long evening. And Martin kept palming his unwanted drinks off on me :-( Consequently, my head's was in less than wonderful state for most of Sunday. Hangovers get a lot worse as you get older, I've noticed.

  • I've been doing more hillwalking. As of a few weeks ago (when Philipp and Bart and I did a moderately epic six-hill hike up by Glen Shee, in beautiful conditions), I have climbed a quarter of the 3000ft mountains in Scotland; as of Saturday, I've climbed all the hills in Sections 1 and 2 of Munro's Tables (out of, er, seventeen sections). Munro-count currently stands at 79 out of 284. Annoyingly, I've now done almost all the ones reachable by public transport, and I'm fast running out of hills that can be reached in a day from Glasgow.

  • The rock-climbing's continuing to be fun. I went to the wall yesterday, and even with my hangover I was climbing stuff I couldn't have managed a few months ago, and I think my technique is getting better. I've got fairly good upper-body strength, so the temptation is to pull myself up the wall with my arms: this is apparently bad technique, as it tires you out faster than if you use your legs, so I'm trying to force myself to push up with my legs more. My other problem is that I don't anticipate enough: I'll get into a position and only then think about my next move, rather than planning two or three moves ahead. This is, again, much more tiring. Incidentally, I could never have anticipated how important balance is for climbing.

    The thing I like about climbing, I think, is how mentally absorbing it is: you're testing your mind and your body at the same time.

  • [info]wormwood_pearl came climbing with us on Thursday, and seemed to enjoy herself. Hopefully she'll come along more in the future. An attempt to interest her in hillwalking last year was a bit of a disaster: though the weather was fine on the actual day, it had been raining heavily the day before, and the ground was waterlogged, so walking through it was less than fun.

  • I somehow managed to put my phone through the washing machine. Fortunately, I have an old Nokia 3310 kicking around to serve as a backup for just this eventuality, and most of my numbers were on the SIM card, which was undamaged; unfortunately, not all the numbers were. The upshot is, if you've given me your number in the last year, I probably don't have it any more.

  • I bought a second-hand laptop from my flatmate Alan, who has a laptop problem in the way that other men have drinking or gambling problems. Poor old delirium's getting a bit battered, with her speakers failing to work half the time. And I had various bits of Windows-only software lying around that I wanted to be able to use, so acquiring a Windows machine seemed like a reasonable idea. And being able to reduce Alan's brokeness was a bonus, too. I've been running Linux predominantly since around 2002, and pretty much exclusively since 2004, so it's weird owning a Windows machine again in all sorts of ways. I've updated it, run malware scans, set secure passwords and created a non-admin account for everyday use, but it still feels rather like unprotected sex, only without the fun parts.

  • If I'm being entirely honest with myself, though, the real reason I wanted a Windows machine was so I could play Portal, which (for those of you who don't already know) is a lovely 3D puzzle game in which you can shoot "portals" onto most flat surfaces, creating a teleporter between your two portals. There's an excellent trailer for the game, which gives you a good idea of the game mechanics; someone's also written a 2D Flash version. But the best thing about the game, I think, is the atmosphere, which is surprisingly creepy and effective. The occasional voiceovers from the insane HAL 9000-style computer are beautifully blackly comic.

    Sadly, Dream (I've stuck with the Sandman machine-naming convention) doesn't cope with it all that well: I've been getting audio stutter, and there seems to be a bug in the video driver which makes the machine bluescreen whenever I try to change the resolution. Upgrading the driver helped - it's stopped bluescreening when I Alt-Tab to another application :-) But Portal's coped a lot better than Half-Life 2, which appears to be missing half its textures: the game world's a semi-transparent mess of wireframes and magenta chessboards, which surely isn't intentional. I'll see if Google or the forums have any ideas. Edit: looks like this is a common problem. Possibly driver-related, but it looks like I should also verify my game cache files and possibly re-extract the game data.

I'm reminded of why I don't post much about my actual life. I can see why people might want to read about, say, if-statements in Smalltalk, but surely nobody cares about this stuff?

More daft ideas [Jun. 10th, 2006|07:32 pm]
[Tags|, , , ]

I keep getting assaulted by daft ideas for things to make - you may remember the achiral fan1, the board games, the telescopic juggling clubs, the reimplementation of TeX in Caml... Sometimes, I get as far as starting to make them before abandoning them uncompleted, but I'd love to finish one one of these days. I blame [info]dynix2.

Anyway, the last couple I've come up with are as follows:

Mathematical fridge poetry. Why write nonsensical bad poetry when you can write nonsensical mathematics? The idea is to get a load of mathematician's names, common terms, prefixes and suffixes, and then to mix them up and produce sentences like "Theorem: for all semi-connected Grothendieck-Riemann lexicography spaces x that are cohomotopically étale, there is a non-gauge-equivalent Erdos matroid Ξx such that ∂Ξx ≈ ∫√O(x). Proof: exercise." For bonus points, combine it with a tabloid-headline fridge poetry set :-) I reckon there could actually be a market for such a thing: Thinkgeek could probably sell a few (speaking of which, this game looks dead interesting). Of course, the magnetic poetry folks probably have a patent on the whole idea of putting words on bits of magnetic paper, but that doesn't stop me making a set for myself. I've bought a sheet of printable magnetic paper: now I just need to choose the words for it.

My first cut at the wordlist for such a thing is as follows: maths/science types (I'm particularly looking at you here, [info]michiexile, [info]weaselspoon, [info]benparker and [info]elvum), what do you think?

Maths words )

Travel Go board You know those magnetic travel games that lose their magnetism slowly and don't stop the pieces sliding into the wrong position? There is a better way, which used to be standard. Instead of using magnets, you keep the pieces on the board using pegs and holes in the board. My parents have travel chess and Scrabble sets that work on this principle. Also, I have a Go board that rolls up, which makes it much more transportable, but the stones are still a bit too bulky. I'd like to combine the two ideas, by having a (small) cloth board with the male half of a snap fastener at each intersection. The female halves (complete with white or black plastic covers) would be the pieces. I'm not sure what I'd put the pieces in when not in play, but hopefully they'd be small enough to fit in a mint/boiled sweet tin (thus getting my own back on everyone who's told me that Go stones "look like Mint Imperials").

The downside is that there are 361 intersections on a full-sized Go board, which is (a) potentially more money than I'd like to spend, (b) a lot of sewing. It turns out that you can get snap-fasteners with bendy metal teeth that can be pressed into place without sewing: I can also find eBay folks selling snap-fasteners in lots of 180 for about £3. Unfortunately, they're the sew-on kind :-(

1 Speaking of which: [info]azrelle, could you please be a bit more specific about where you get your fan guards from? I've tried in a couple of art shops and had no joy.
2 I wonder what would happen if [info]dynix (who among my South London friends can be and is blamed for anything) were to meet James Needham (who fulfils a similar role among my Light Entertainment friends). Possibly a gigantic scapegoat made of electricity would materialise and suck all the atoms in the Universe into itself, ushering in a new order of things. But come to think of it, why haven't they ever met? What are the odds of two people being blamable for any conceivable thing and yet never appearing in the same room at the same time????? I shall watch them closely: maybe one day [info]dynix will say "What-ho", or James will let on that he's not so ignorant about computers, and then I will know their secret...

More games, and a Visitor from Down South [May. 23rd, 2006|05:00 pm]
[Tags|, , , , ]

Elizabeth came up from Oxford on Sunday to give the Geometry seminar on Monday afternoon. She was speaking about her DPhil work, which is fairly hard-core algebraic geometry (specifically, she's using geometric invariant theory to construct coarse moduli spaces for stable maps). None of us were very familiar with the background material, and so she'd put in some explanation of the ideas used: it was all clearly presented, but there was quite a lot of it, so the pace was a bit fast. I got quite a lot out of it, though. After the seminar, we went to dinner at Balbir (seriously posh Indian restaurant on Church Street) with [info]susoeffl and the seminar convenor, then Elizabeth, [info]susoeffl and I returned to my flat to drink gin and bizarre Welsh slivovice/whisky and to eat cheesecake that the lovely [info]wormwood_pearl had prepared. Then we played a couple of rounds of Carcassonne until it was time for Elizabeth to get her train back to Oxford. It was excellent to see her again, and to hear her explaining her thesis topic at length and while I was sober for a change :-)

I'm increasingly impressed with Carcassonne. The game mechanics are wonderfully simple and elegant. It seems like it would benefit from more depth, but maybe there's depth there that I'm not seeing yet. And there doesn't seem to be much incentive to cooperate: maybe playing doubles (a la croquet) would help.

Anyway, I've been thinking a lot about games of that sort recently, and this morning I came up with an idea for one.

Tobacco Lords of Glasgow (working title) )

I mentioned this to [info]wormwood_pearl, who immediately suggested a better idea:

Escape from Cessnock! )

If either of these get off the ground at all, I'll post some more here...

1: Buckfast tonic wine, the preferred drink of Scotland's disadvantaged young folk.
2: The aforementioned disadvantaged young folk. The Scottish equivalent of chavs. (spits, disinfects mouth after using foul classist word)
3: The upmarket, overpriced halls favoured by students with more money than sense.
4: As any student will tell you, the parks are full of gangs that will gang-rape you if you venture in after dark. [info]the_barlow informs me that this is bollocks, though some of them are used as cruising spots by gay men.

Playing games [May. 19th, 2006|03:30 pm]
[Tags|, , , , ]

I've started playing Go again after almost a year off. It's great, but the rest has not helped the standard of my play. I've mostly been playing against Philipp, but I got a few games in at The Burn (about which I will write soon). Won three and lost one against someone I'd taught to play, won one and lost one (heavily) against a Chinese guy called Qiming. The game I won was an exhibition game, in which we explained what we were doing to the gathered audience (no, really). Getting a window on his strategic thinking (much more developed than mine) helped, but the really helpful thing was when Philipp said "But isn't this group here dead now?" Indeed it was, and that forced Qiming to choose between saving that group (and losing its corner) and saving the group that was then in contention. He saved the corner, and I went on to win the game :-)

Philipp's getting worryingly good, actually. I've already taught him everything I know about strategy, and he makes fewer stupid mistakes than me. I should probably read more of my Go book. And, you know, play more. We had one good 13x13 game on the way back from the hills on Saturday, played on a bit of paper. I had a live group containing most of the left side of the board, but I reckoned he might be able to make two eyes in that bit of territory. Hoping he'd decide not to risk it, I passed, and so did he. We counted up, I'd won, and so I said "You know, I'd have tried to make two eyes in that big wodge of territory on my left. You could probably have managed it." So we restarted the game, and he beat me by as much as I'd beaten him before :-(

Also, while I was away at The Burn, an eBay purchase arrived: inspired by this blog post and a recommendation from [info]johnckirk, I'd ordered a copy of the German board game Carcassonne. Richard said that he'd played it before, so we invited him home for dinner and a couple of games. It's excellent fun, and fifteen quid very well spent. Little or no setup time, about an hour's play, good balance between luck and skill, very sociable. My only gripe is that it could do with more tiles and a longer playing time.

[Yes, I know I said I'd stop reading ESR's blog. I have at least managed to stop commenting on it. By the way, the Greg Kostikyan mentioned there is the one who invented the term grognard capture, which I blogged about a while ago. Small Internet, eh?]

While I'm talking about games, this is one of the funniest things on the Internet. What would happen if a Karate Kid-style sports movie starring Leonardo Dicaprio were made about Go?
