UPDATE: /1165/loomiere-2-0-1-beta-finally-out/ OK folks, things have settled down and we are good to go. After some considerations the legal concerns for Loomiere/Stream are now cleared and gone. The source is now released and will be available indefinitely. Again, this streamer (minimally customized) has already been serving all the
Read moreSeven essential WordPress plugins
Here are the plugins I recommend for use on a WordPress blog. Most (not all) of these plugins are generic, meaning that they are not bound to a specific type of blog and may (or should) be used regardless of what you write. All of these plugins are
Read more@font-face for a programmer’s blog?
I’m sure that many of you are well aware of the exceptional @font-face CSS3 rule, which made life much easier for many designers, I would think. A few days ago I started wondering if it would be appropriate to use such an instrument on my blog… the site
Read moreURI 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
Read moreFirst 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

UPDATE: http://vpalos.com/1165/loomiere-2-0-1-beta-finally-out/ The Loomiere (0.2.1) code is now freely available under GPLv3. Please see this post for an update. Are you killing psstream? Well, yes! I am sure that many of you already know about psstream (the PHP streaming extension I made a while back). Well, many things happened

Version 3 An even better method is: find “$target” -type f -exec chmod -c “$mode_files” {} \; \ -or -type d -exec chmod -c “$mode_dir” {} \; A true one-liner! 😀 Version 2 A better method is this: find “$target” -type f -exec chmod -c “$mode_files” {} \;
Read moreBash URI parser using SED
Warning! This version is now obsolete! Check out the new and improved version (using only Bash built-ins) here! Here is a command-line (bash) script that uses sed to split the segments of an URI into usable variables. It also validates the given URI since malformed strings produce the

Disclaimer This article explores a way in which an approximate “fingerprint” of a file tree can be created! If all you want is to detect file changes a much more appropriate method would be to use inotify/incron. Version 2 (update) Another, much faster method would be to use

UPDATE: Steven pointed out (very nicely) that there’s no need for cat in this picture, grep would do just fine on its own. So, thanks Steven! Detect how many CPU cores are present on the running machine: grep -c processor /proc/cpuinfo This can be very useful when writing
