Hi!
I’m Valeriu — still the kid fascinated by building the world; just with better tools. Lately, some of them are about making math visible and easy to get.

Anastasia
My blog is about programming, that’s a fact and while I never broke this tradition so far, today I feel like making an exception. Why, you ask? For her: mademoiselle… Anastasia. 😀 She was born on the 5th of January, 2011 and she really wanted to say “Hi!” on daddy’s blog. Who am I to…

Loomiere 2.0 teaser
UPDATE: http://vpalos.com/1165/loomiere-2-0-1-beta-finally-out/ This article is a quick peek into how Loomiere 2.0 is (currently) serving close to 3k active streams from a single server in production which is restricted to 1.6 Gbps of bandwidth (we are currently negotiating with our ISP to raise this limitation).

@font-face for a programmer’s blog?

URI parsing using Bash built-in features
A bit of background A while ago I posted an article describing how one could parse complete URIs in Bash using the sed program. Since then, I have realized that there is a better way to do it, a much better way: via Bash built-in pattern matching! Here are some benefits of this improvement: It…

First impressions on Loomiere/Stream performance
UPDATE: http://vpalos.com/1165/loomiere-2-0-1-beta-finally-out/ As promised, here are some of the first monitoring statistics of Loomiere/Stream in a production environment after moving away from psstream. Only one server is considered, a Quad-core Xeon with 8GB RAM (not that they are used anymore). This shows the memory usage over one week (the switch was made on the 29th as…
