This guy really hates Penrose: "...Penrose and others have spec- ulated that gravity is crucial for a proper understanding of quantum mechanics even on small scales relevant to brains and laboratory experiments, and that it causes non-

I totally agree. I sat silent at europy in 2006 as guido explained he was breaking the print statement. At europy in 2007, when he gave the same talk, I boo-ed, loudly. He said "well no-one complained when I talked about this last year

I had a look at the group theory page. This is definitely something that should be taught more in basic math so I was glad to see it there. But I must admit i was disappointed at the notation: yes it's colourful, but totally useless fo

The lead developer on Elefant got poached by a high frequency trading shop in 2006. He was "discovered" showing his wares at pycon that year (vectorized operations faster than anything else out there). Sigh.

You don't need alot of topology to at least get started with knot theory. Eg. the Jones-Conway polynomial or the Kauffman bracket are easy enough to understand and do calculations with. The amazing thing about the Ghrist book is how mu

I'm wondering if software defined radio has anything to contribute here. Ultra wideband could help to mask the radio signals. Software defined antenna's could help with the directionality problem. This stuff is expensive today, bu

Aha, right.. That helps me understand the link to optimisation. So the point of spheres getting "spiky" is that if you are searching for the inside of the sphere then you need to go into the spike which gets harder and harder to find as t

i would recommend tango dancing (!= ballroom). Alot of engineers, scientists, etc. really get it. It's not about memorizing moves, it's about learning a logic, learning how to think with four legs. It's alot of fun. Oh and there's babes too

What about something like "netflix for comments?" Ie. your votes would endow you with a profile (a sparse vector) that then tailors HN so that you see more of what other similar users also upvote. This would also encourage people to vote mo

Probably 10 - 50 million. You will need 5 - 10 hard core programmers, a network engineer, a trader or three, a bunch of the fastest servers around, etc. etc. This is an insane idea, I would not recommend it! (The margins are being pushed to

I use the hag capisco. Works well for keeping my energy "upwards": strong firm seat that rotates the hip forwards. I find the aeron too saggy. You can get it with or without a backrest. I don't use a backrest cause that forces me not to slo
