I don't think it makes sense to choose your logging framework based on performance. Logging does IO, so it's relatively slow compared to everything else you do -- but operationally it's invaluable. I'd take the performan

A friend was doing this in Philadelphia last year and has started doing it in SF http://tea.byankit.com/ . Not sure if this idea was inspired by that or an independent discovery -- the design of the pages looks samey but I t

Perhaps the most interesting and useful fact about the harmonic series is that the nth harmonic number (the partial sum of the first n terms) is an extremely accurately approximation of ln(n) (they are very close for all values of n, in the

On the plus side, this makes it very pleasant to travel to Argentina if you're from the US. Just don't forget cash.

All institutional investing today is based off arbitrage. The only thing strange about HFT is that a computer does it.

I worked on a similar system at somewhat larger scale (maybe 5-10x larger volume and dataset size). There's a lot of basic JVM tuning to be done. You have to monitor heap usage and GC pauses and keep manipulating heap size, perm gen si

the choice of projects seems somewhat arbitrary. i've only contributed to one (python), but i can definitely say that many of these codebases are total messes (drupal, libreoffice for sure) which would make me _not_ want to work on these pr

I don't work on anything with a README that is for nontechnical users, and I don't produce technical material for anything other than UNIX. No one I work with that I care about pleasing uses it. I'd rather stick with the tried and true conv

This is a great piece of software in terms of presentation and ease of use. However, it can make your life difficulty if you want to do anything outside of the scope that the authors intended. It's very difficult to build dynamic UIs with c

I agree. What I wrote here was based on that. I wanted my post to be more akin to a tutorial than a reference. I don't think the data model reference is useful to people who don't know the basics -- the idea was to bridge that gap so that i

This was my work (not sure why someone randomly posted it here, but such is the internet). I do exactly what you just described, see http://www.rafekettler.com/magicmethods.html#appendix
