Reddit’s /r/ProgrammerHumor has recently treated us to this politically incorrect and quite childish little Open Source rant Obviously, like most “discussions” on reddit and specifically those discussions about Open Source, things got quickly very serious with people referring to Richard Stallman and how these critiques are childish and immature and what’s-wrong-with-our-industry™ etc. Let’s not delve … Continue reading Open Source…

Many of us geeks don’t really care about users, tractions, etc. when we spam GitHub with our little toy projects. I mean, who knows if we really have the time to maintain them? Certainly, there’s almost no money in it anyway, so we might just as well give it away for free (e.g. jOOX). Nonetheless, … Continue reading An Open…

Last year Zone-H reported a record number of 1.5 million websites defacements. 1 million of those websites where running Apache. When it comes to configuring a web server, some people tend to turn everything on by default. Developers are happy because the functionality that they wanted is available without any extra configuration, and there is […]

Most ORMs support the concept of dynamic finders. A dynamic finder looks like a normal method invocation, but the method itself doesn’t exist, instead, it’s generated dynamically and processed via another method at runtime. A good example of this is Ruby. When you invoke a method that doesn’t exist, it raises a NoMethodError exception, unless […]

Nicholas Tang wrote a nice little perl script that shows a basic memcached top display for a list of servers. You can specify thresholds, for instance, and it’ll change color to red if you exceed the thresholds. You can also choose the refresh/sleep time, and whether to show immediate (per second) stats, or lifetime stats. […]

Developed by Simone Carletti, ApacheLogAnalyzer2Feed is a really powerful open source PHP 5 class to parse and analyse Apache Web Server log files. Results are converted into a feed to let users subscribe them with a feed reader. […]

Rsync is great, however, it only synchronizes files in one direction. Unison, on the other hand, synchronizes both ways. It allows two replicas of a collection of files and directories to be stored on different hosts, modified separately, and then brought up to date by propagating the changes in each replica to the other. Why […]

When you develop or deploy an application, dependency tracking is one of the problems you must solve. Keeping track of dependencies for every application you develop is not an easy task. To solve this problem I’ve created Zend_Debug_Include, a Zend Framework component that supports automatic dependency tracking. We all agree that dependencies cannot be maintained […]

During his keynote presentation at OSCON last year, Ubuntu founder Mark Shuttleworth described application extensibility as an important enabler of innovation and user empowerment. Citing the Firefox web browser and its rich ecosystem of add-ons as an example, Shuttleworth suggested that the Linux community could deliver a lot of extra value by making scriptable automation […]
