Pdf shuffling in LaTeX

Pdfpages is a LaTeX package that lets you drop individual pages of other pdfs into your LaTeX documents. Put it together with the \foreach command provided by pgf/TikZ, and you can get quite a bit done very simply. For instance, you can scan in somebody’s photocopy of a paper from 1978 using the office printer, [...]

Two kinds of ebooks

Suvudu.com recently gave away a bunch of ebooks1 in pdf format. I was pretty surprised by the reaction: people were angry because the free stuff wasn’t the right free stuff. They didn’t want pdf, that was pretty clear. Now suvudu are offering a bunch of other formats, but it got me thinking about why I [...]

Dumb DRM arguments: ebooks are not music

I’d like to celebrate read-an-ebook week with something positive, but I don’t have anything even half-prepared except some thoughts about DRM. That’s bad enough, but I won’t even be arguing against DRM for ebooks. I certainly won’t argue for it — I’m against the idea on principle, so if I thought it through and concluded [...]

Downtime, fixed (wp-cache and dreamhost)

Apologies for the downtime, if anyone noticed. Short explanation (i.e., geekery) follows.

Addictive ‘Life’ tutorial

Irregular Life is a flash game which will get you addicted to Conway’s Game of Life. I played to about level 15 just by symmetry-guessing –you see three gaps in a pattern and you’ve got three squares to place– so it’s not that hard, at least in those early levels. That’s not really the point, [...]

Gödel’s Second Incompleteness Theorem…

… Explained in Words of One Syllable, by George Boolos (not Boole). If it could be proved that two plus two is five, then it could be proved that five is not five, and then there would be no claim that could not be proved, and math would be a lot of bunk. If you’ve [...]

Iterated Beer Response

We’re back from Greece with many photos and stories, which I’ll start putting online in the weekend. For now, a geek-out interlude, mixing work-in-progress from the office (not my own work, admittedly, but the desk next door) and beer.

Mario Bros in lego

Ok, it’s via BoingBoing, but it’s too cool not to share. A stop-motion Mario Brothers sequence in lego, with music by recorder and sound effects by voice. Delightful.

How not to set your auto-reply

Geek insomnia

Ok, so having a laptop sometimes isn’t a bonus. Obviously if I go to bed too late, I don’t get enough sleep. But also if I go to bed too early, I end up staring at the ceiling for hours and … don’t get enough sleep. So the trick is to hit bed early, but [...]
