If you had asked me whether or not it was possible to get a 2x speedup for my LazySorted project by adding a single line of code, I would have told you "No way, substantial speedups can really only come from algorithm changes." But surprisingly, I was able to do so by adding a single line using the __builtin_prefetch…
Deep learning has become something of a buzzword in recent years with the explosion of 'big data', 'data science', and their derivatives mentioned in the media. Justifiably, deep learning approaches have recently blown other state-of-the-art machine learning methods out of the water for standardized problems such as…
MySQL and MongoDB are both popular, yet poor representatives of their species

Here’s a followup to last month’s post about Penrose Tiling in Obfuscated Python. The Mandelbrot set is a traditional favorite among authors of obfuscated code. You …
In the past, walking the uneasy borderline of academia, I used to managed compute servers for my research group. New hardware was a rare godsend, configuring it by hand was natural. At 99designs, I’ve been privy to the opposite approach: machines should be disposable. This requires the entire setup of a new machine to…
While none of the ideas in core.async are new, understanding how to solve problems with CSP is simply not as well documented as using plain callbacks or Promises . My previous posts have mostly explored fairly sophisticated uses of core.async , this post instead takes the form of a very basic tutorial on using…
I returned back home from PGCon.EU-2013 conference, Dublin, Ireland, where we gave two talks - Next Generation of GIN and Binary storage for nested data structures and application to hstore data type . These projects as well as visiting the conference (I, Teodor Sigaev and Alexander Korotkov) were…

If you’re a regular reader, you might have noticed that I’ve been on a quest for the perfect backup program , and ended up writing my own encryption layer over bup.
This post is a work in progress.Inspired by a recent purchase of the Red Book, which providesa curated list of important papers around database systems, I’ve decidedto begin assembling a list of im...
This article will try to convince you that adding some limitations on legal Unix/Linux/POSIX filenames would be an improvement. Many programs already presume these limitations, the POSIX standard already permits such limitations, and many Unix/Linux filesystems already embed such limitations so it'd be better to make…
This post was too inflammatory and abusive in nature, and I regret writing it. It did exist, and you can probably can find it using the web archive. UI is hard.
Every once in a while, I find that someone is interested in AngularJS, but not sure if they should stick to their jQuery comfort zone or mak...
In this post, we consider the problem of selecting the \(i\)-th smallest element from an unsorted list of \(n\) elements. Somewhat surprisingly, there is an algorithm that solves this problem in linea
