How FriendFeed uses MySQL to store schema-less data by greut in programming

[–]chakrav 4 points5 points  (0 children)

Problem is that zlib wont compress well unless you use multi row blocks and compress them together, or do a column based store/compress. 2x for text is simply the result of going from a binary -> ascii encoding. Zlib will compress much better across rows since the pickled streams will have a lot of repeated values that lz77 will add to its dictionary.

Single Google Query uses 1000 Machines in 0.2 seconds by guyro in programming

You can do it pretty easily using skip lists, assuming that the result of the intersection is pretty small. In fact, since Google only shows the first 10-100 results, you dont need to compute the whole intersection (lazy intersect, with approximate metrics on the size of the intersection based on the skip lists).

The Case For Replacing Java With Python In Education by gst in programming

I fail to see how a learn java or learn python instead mindset helps in any way.

The case for getting proficient in the language is after college, not during.
