Setting Up A Subversion Repository Using Apache, With Auto Updatable Working Copy

Post date: June 19, 2007, 02:06 Category: Miscellaneous Views: 3047 Comments
Tutorial quote: Subversion is a free/open-source version control system. That is, Subversion manages files and directories over time. A tree of files is placed into a central repository. The repository is much like an ordinary file server, except that it remembers every change ever made to your files and directories. This allows you to recover older versions of your data, or examine the history of how your data changed. In this regard, many people think of a version control system as a sort of time machine.

Installing and securing Squid

Post date: March 13, 2006, 15:03 Category: Software Views: 4749 Comments
Tutorial quote: Squid is a high-performance proxy caching server for web clients, supporting FTP, gopher, and HTTP data objects. Unlike traditional caching software, Squid handles all requests in a single, non-blocking, I/O-driven process. Squid keeps meta data and especially hot objects cached in RAM, caches DNS lookups, supports non-blocking DNS lookups, and implements negative caching of failed requests. Squid supports SSL, extensive access controls, and full request logging. By using the lightweight Internet Cache Protocol, Squid caches can be arranged in a hierarchy or mesh for additional bandwidth savings.

After the installation and base configuration of squid we will add another layer of security by chrooting it.

Change Ctrl + Alt + Delete Behavior To Open System Monitor, in Linux

Post date: September 24, 2009, 12:09 Category: Miscellaneous Views: 2015 Comments
Tutorial quote: Actually, I've written this post before (quite a few months ago) but then deleted it because it didn't work. In the mean time, I found out why, so I decided to post it again. I find pressing Control + Alt + Delete to open up System Monitor to be very useful, especially for Windows users who are used to it and may actually press this quite a few times before realizing it doesn't do anything or what it does in Windows. Using System Monitor, you can preview all running processes, end or kill them, see how much CPU a process is using, CPU + memory + network history, available disk space and even change how much CPU a process should use.

There are 2 ways of changing Ctrl + Alt + Delete behavior to open System Monitor: one if you are running Compiz, and one for Metacity, only to use if you are not running Compiz.

Installing Tomcat6 With SUN-Java & Apache2 Integration On Ubuntu 10.04

Post date: February 2, 2011, 13:02 Category: Installing Views: 2278 Comments
Tutorial quote: Apache Tomcat (or Jakarta Tomcat or simply Tomcat) is an open source servlet container developed by the Apache Software Foundation (ASF). Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems, and provides a "pure Java" HTTP web server environment for Java code to run. Tomcat should not be confused with the Apache web server, which is a C implementation of an HTTP web server; these two web servers are not bundled together. Apache Tomcat includes tools for configuration and management, but can also be configured by editing XML configuration files.
