I’ve been using Redmine for several months now. During this period of time I had the chance to evaluate most of its features. Although I still consider it one of the most feature-rich project management web applications currently available, using it on a production website revealed some weaknesses in the anti-spam area. Truth is the…
The PHP interpreter supports running it in interactive mode by using the –interactive (short equivalent: -a) command-line switch. Running an interactive PHP shell can be useful when you need to quickly try code snippets. But, for this mode to be fully functional, PHP has to be compiled with readline support. Unfortunately, on CentOS PHP has…
About a month ago, I had finally decided to start writing a simple web-based VCS manager. This is a project I had been thinking about for the last 2 years as a solution for source-code management at CodeTRAX.org, but I never really started development. The initial plan included support (repository creation only) for the most…
rdiff-backup is my favorite tool for keeping backups on Linux systems. Today, I started using it on a Windows 7 desktop as well. At first, I used rdiff-backup from the cygwin project, but I soon noticed that, if I did anything else that required moderate hard disk access on the computer on which the cygwin…
I’ve been using the Subversion version control system during the last 2-3 years. Although a VCS has never been a top priority for me, it seems there is always room for version control. I ended up using it for almost everything, from simple to more complex scripts and even system configuration files in some cases.…
This is a quick note that mod_wsgi daemon processes are now incompatible with mod_python. Upgraded mod_wsgi earlier today in CentOS and saw the following note. I guess this limitation has been around for a while before affecting CentOS/RHEL:
Permanently removing deleted posts and topics in bbPress can be cumbersome. bbPress does not provide a decent way to completely remove deleted content from the database. I am not sure why… In my case, these posts mostly contain spam and there is absolutely no reason to keep them in the database any more. As it…
I just read this very interesting article about the new 4096-byte sector hard disks, like the new Western Digital Caviar Green drives, and the impact a partition misalignment might have on the drive’s write performance.
The last incident with the php-cgi errors as a result of a bad PHP script made me re-evaluate the daily reports I receive from the server. I realized that a report about the httpd errors that have occured during the previous day, including all virtualhosts, is more important than I had initially thought. Such a…
This is just a quick notice that during the last five days there was a problem with the website feeds. The web server returned a 500 Internal Server Error to almost all requests for /feed/ URLs. Also, there was a big increase of the server’s CPU load behind the scenes, which was caused by php-cgi…
