I ran the marathon again! This was my slowest marathon by more than half an hour (i.e., by 31 minutes); I finished in 4:41:53, with a half split of about 2:07. But I under-trained this season, and very nearly didn't run it at all due to knee problems, so I am happy to have met my only goal, which was to finish. Also I feel less wrecked the day after than I have any other time.

This is mostly the same outfit I ran in last year except with more garish socks and shoes. Photo by +Alan Vee around mile 14.

SIGBOVIK makes the news. I love the speculative future work section, which is actually pretty lucid, and the work of the journalist, not +Tom Murphy VII at all.

did you know that after 8 perfect shuffles, a 52-card deck is back in its original position?

this afternoon decided it wanted me to hack up a program to visualise different shuffling methods. other interesting results include that with a 45-card deck, pile-shuffling with 5 piles will turn the deck backwards after 11 times.

SIGBOVIK. Tomorrow (monday) evening, 6pm. Rashid auditorium.

Don't miss.

"How many english tweets are there?" "Well, text ebooks compress to 1/8x. So the average ASCII byte in text is one bit of entropy. So there are 2^140 tweets." (http://what-if.xkcd.com/)

Information theory is the sexiest. Why am I not studying it.

15-410 veterans might be pleased to see I've been working on a new program to run in the Pebbles userspace.

I suspect my linguaphile friends will love this IF game. My only lament was that I wasn't able to create "tea" from a "tear" (or turn the "world" into a "word").

here are some pictures I took on while on a run several weekends ago.

I brought my camera along 'cause I felt like celebrating the fall colours, but the route ended up being very hilly, so I also tried to focus a bit on how three-dimensional Pittsburgh is.

I dispute their choice of stock photo (it is so comically bad that it might just be a "how many things are wrong with this picture" game) but this is really super good news.
