Counting bytes is the wrong thing to do (for old disks). If you count disk seeks (as you should), LSM trees are a lot better than B-trees, but it turns out you sacrifice more read performance than you should. On SSDs, you do want to count

Is anyone else struck by the antiquated nature of the (what is that, a roff?) format? Why, for an "internet draft" is this page not the default format: http://tools.ietf.org/id/draft-ietf-appsawg-xdash-02.html ?

MySQL with TokuDB handles write-heavy OLTP workloads well, even with multiple complicated indexes. Since it uses Fractal Tree indexing, writes are so fast that locks aren't held long enough for this to become a problem.

Dark background and light text is much more natural for a screen. Light background and dark text works for paper, but makes no sense on a screen, it's like staring into a lightbulb.

emacs bindings in copy mode is nice (and there are vi bindings if you're a heretic) split screen functionality in tmux is annoying but I hardly use it

This post seems to miss the point that the major hurdle faced by a 14-year old trying to learn how to program and find the right libraries etc. to use is solved by Google itself.

FWIW, I've switched to tmux but think tmux's implementation of split screen is broken and desperately miss screen's. Screen lets each part of a split screen select a different existing window. Tmux makes both parts of a split part of a sin

With pleasepoach.me, it seems that choosing 11 candidates means paying $550 (but you get to look at 110 candidates). Am I wrong?

What I don't understand is: why don't the recruiters that do carefully screen people just wipe out those that don't? Are there enough companies that are too clueless to hire a good one that the bad ones still get enough results to keep d

Mainly: why are make and gcc not installed?
