On Amazon book scanning

Today was the first time I clicked on these buttons in Amazon that allow you to look at a few pages of a book. That is some Ajax application (which of course warned me first with some fancy schmancy Ajax popup, fading the window etc. that they only support Firefox, IE etc., ignoring the fact that Epiphanys rendering engine is, well, the same as Firefoxs'. I actually clicked the Ok button twice before it finally closed...)

Anyway, what I want to share with you is a screenshot of some malfunction:

Amazon look-inside disfunction

So apparently they scanned the page word-by-word; often clipping the lower part (notice the missing parts of the p, g, y letters in most words). Some words have gone missing altogether (before "life"). However, the page appears to be a Jpeg image; you can see some compression artifacts around the words that are not my fault (you might need to zoom the image).

So it seems like they disassemble the pages when scanning, then reassemble them to present them to the user. Sometimes messing up the background color, like in this example... interesting. Is there much data storage to be saved by merging word images and storing them only once? Are they reassembled on-demand?

On games

Lars, of course billard balls don't shoot back, if you hit them with a lame stick. Use some real weapons, and they'll probably shoot back. Try some rocket launcher.

To me, the best shooter is the original QuakeWorld TeamFortress. Screw non-Linux-supporting modern stuff like counterstrike. It's boring.

I think I never played any shooter beyond Quake3, actually. That one didn't care about being "realistic" (which sucks) but was about fun and arcade.

Oh, make sure you don't install sgt-puzzles. Best make any local packages of yours (say... your self-compiled kernel with suspend2) conflict with it. It's just a couple of tiny games, with very simple rules. But they totally take over your mind.
