ycombinator and things I read

Recently a friend of mine send me a link to ycombinator - great resource for someone like me. So, if you like to read things that are more pragmatic then going deep but stay focused on one technology, methodology or technic, then this is something like /. but more techie. Simply I love it, usually, really short articles behind, on various subjects. Some time ago I spend tremendous amount of time looking for some good resources of techie knowledge, and so far /. is the only thing I am using on daily basis, but ycombinator seems to be great as well.

In terms of books, recently I read:
Knuth's The Art Of Programming (first 3 tomes)
Avodey's Category Theory (Oxford Logic Guides)

I enjoy reading few books at this same time (well, almost this same). When a part of book, or some topic is not really interesting, I switch to second book, and give my brain a fresh topic.

In terms of Knuth's books, I enjoy the way how they are written, easy to read, with sense of humor. Excellent exercises at the end of each topic. I don't like the MIX language. It is too old fashion to me. Sometimes, dealing with the language is harder then the algorithm itself, and a problem is more about how to write the code well (or even, how to write it), and not how to deeply understand, why some operations take place, and why they are done now, and that way. But still I recommend this book.

I spend some time deciding between Category Theory (Oxford) and Basic Category Theory for Computer Scientists (MIT). The O book is newer and bigger than M book, but also more expensive. I made a decision, base on fact that I am more Oxford then MIT boy (sorry chaps:)). So far I love it, easy to understand, lot's of new stuff to learn. I don't see to many exercises that are good for me, and It makes it hard to test new knowledge.
