I'm hand-typing the code from the pdf. I know it would be easier if I used the .lhs file from github, but I'd like to make sure I read and understand the code first. Reading the .lhs file hurts my eyes due to formatting issues in Emacs.

Of interest for the data science angle. Also it includes the word "bayesian" and links to Paul Graham. That's got to make it more or less on-topic, right?
I recently took this collection of text messages (from Hilary Mason's collection of research-quality data sets ), and attempted to build a simple Bayesian spam filter for text messages.
This was mostly just a fun exercise. I wasn't expecting to produce a usable product (and I didn't), but as an exercise it was pretty informative and well worth my time. I've put some observations in rot13, as anyone else undertaking this exercise may benefit from observing them by themselves.

If anyone else tries this, let me know how you get on.
This is great, thanks. I'll implement a rudimentary spam filter with this sometime next week.
Well, try this: Show how general abstract nonsense could be relevant to a rationalist in his day to day life or in his general understanding of the world. Or try an introduction to general abstract nonsense that does not leave the reader with the feeling that it is, well, general abstract nonsense.

Nonfiction Books Thread
Language in Thought and Action, by S. I. Hayakawa. It goes without saying that this book is highly recommended. To those who've read the sequences, and have therefore had just a bite of the hearty meal, you should really get it. An anecdote about how I came to find this gem: My grandfather is a retired linguist, and in his library, in a house I grew up in, he keeps, and still has, a gigantic collection of books. A member of that distinguished class of "books older than me", this book is a part of his linguistics collection, and I didn't even know he had it until a few weeks ago when I was having a conversation with my uncle in said library. The title jumped out at me, and I haven't been this happy about finding a book in that room since I found my mother reading Kahneman.

Music Thread
Chillstep : I've found this online collection to be quite relaxing, as the genre name suggests.
The Art Of Noise - The Seduction of Claude Debussy : I hadn't listened to any music by this super-group before this year, and now they're one of my favourite groups...I'm either fickle or these guys are awesome, and I'm not fickle. There's one song I liked in particular, Metaforce, and its remixes. It'll show you just how versatile this group is, with the rest of the album as a backdrop.
I concur with dbaupp's suggestion.
Additionally, you can try the reframing technique. Anna describes it here:
When facing a difficult decision, I try to reframe it in a way that will reduce, or at least switch around, the biases that might be influencing it. (Recent example from Anna's brother: Trying to decide whether to move to Silicon Valley and look for a higher-paying programming job, he tried a reframe to avoid the status quo bias: If he was living in Silicon Valley already, would he accept a $70K pay cut to move to Santa Barbara with his college friends? (Answer: No.))
The example she gives isn't quite isomorphic to the choice you're making, but I think the technique still may be worth trying. Imagine you're currently living out one option but given the chance to take the other - how would you feel about it? And vice versa.
I don't have anything specific to offer, but (in theory) hard choices matter less. And if you literally can't decide between them, you can try flipping a coin to make the decision and as it is in the air, see which way you hope it will end up, and that should be your choice.

Happy New Year, LWers, I'm on a 5 month vacation from uni, and don't have a job. Also, my computer was stolen in October, cutting short my progress in self-education.
Given all this free time I have now, which of these 2 options is better?
- Buy a road bicycle & start a possibly physically risky job as a freelance bike-messenger within my city ( I'm that one guy from Nairobi )in order to get out of the house more, then buy a laptop and continue my self-education in programming, computer science, philosophy, etc.
or
- buy a laptop, do quick and easy wordpress websites for local businesses, then buy the bike and use it for leisurely riding under no pressure? I only have money for either one or the other for now, and for some reason I'm hesitating. Maybe it's because I want to do both. This is important to me, and I'll appreciate any discussion on this. Thanks.
dbaupp, ParagonProtege, thank you both for the links and suggestions. I'm going with the laptop. Anything else I could do (naturally, there's a lot i want to do) will be kickstarted by the modest, but easy(ish) money I'll get by doing ~$100 websites, as I upgrade my code-fu for Other Stuff. ;)
I also haven't cycled actively for years & I'm afraid my unfit body might conk out on me, making me unable to Do The Job once I commit. Cliff scaling is much harder than hill climbing.
From Alicorn's post , I can easily tell that after I get the laptop, the correct thing to have would be a bike, since I can ease myself back into cycling regularly. It's also weird how I saw the Other Option (buy bike, work, afford laptop, buy laptop, cut down on bike work as I increase study & laptop work hours) as just as good, even though I know I will feel like a flake if I stop riding after it gets tougher and more tiring, which is more likely than giving up on wordpress. Wordpress isn't even the only option for devastatingly easy Internet work.
