Programming
The past couple of years have seen an explosion of open source programming languages and utilities that are geared toward children. Many of these efforts are based around the idea that, since the days of BASIC, programming environments have become far too complex for untrained minds to wrap themselves around. Some toolkits aim to create entirely new ways of envisioning and creating projects that appeal to younger minds, such as games and animations, while others aim to recreate the “basic”-ness of BASIC in a modern language and environment.

Adobe Air for Linux is finally out of beta. With this latest version, you will now be able to install Air applications that previously don’t work in Linux. It put Linux users on level ground with Mac and Windows and you won’t see anymore Air apps that are only Mac or Windows compatible. In addition, this Adobe Air for Linux is compatible with Flash 10, which means you can install the Adobe Air app right from the website, rather than download the installer to your system and use the Air application installer to install. The support for Flash 10 also marks a great step forward as it now allows Linux users to access to media intensive applications and apps that use digital rights management (DRM).

This tutorial shows how you can set up an OpenSUSE 11.1
desktop that is a full-fledged replacement for a Windows desktop, i.e.
that has all the software that people need to do the things they do on
their Windows desktops. The advantages are clear: you get a secure
system without DRM restrictions that works even on old hardware, and
the best thing is: all software comes free of charge.

This is a detailed description about how to set up an OpenSUSE 11.1
server that offers all services needed by ISPs and hosters: Apache web
server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND
DNS server, Proftpd FTP server, MySQL server, Dovecot POP3/IMAP, Quota,
Firewall, etc. This tutorial is written for the 32-bit version of
OpenSUSE 11.1, but should apply to the 64-bit version with very little
modifications as well.

Control Panels
Webmin is a web-based system for Unix, Linux, OpenSolaris, and recently added Windows based Operating Systems that allow you to take full control of your server through a popular control panel and web-interface. What Webmin does is it allows you to simplify the managing course of action with a Unix and/or Linux system. You can manually edit and configure files as well as run commands to create/delete accounts, set up web servers, or manage email forwarding. You’re able to complete all of these tasks through a trouble-free web interface specifically designed for the user.

Virtualization
Use virtualization software? Check out VirtualBox 2.1, which adds some exciting new features:
* Support for 64-bit guests on 32-bit host operating systems. Testing a 64-bit desktop is now much easier thanks to VirtualBox supporting 64-bit guests on 32-bit hosts. It’s pretty impressive that this is even possible!
* Experimental 3D acceleration via OpenGL. Don’t get too excited about 3D acceleration yet. For now only OpenGL on a 32-bit Windows guest is supported. DirectX support is planned, which means that 3D gaming in a VM could become possible.

Virtualization
Running a server as a guest in a VirtualBox virtual machine isn’t much good when you can’t network with the guest OS from your host machine. Instead of setting up host interface networking, you can simply port forward though VirtualBox’s NAT. Once port forwarding is set up, any computer on your network will be able to network with your guest OS though forwarded ports on your host.
VirtualBox’s GUI doesn’t expose this functionality, but the VBoxManage command line utility does. Before starting, remember to close your virtual machine before changing it’s configuration.

In this article I will explain how you can reduce server load by using memcached together with your vBulletin
forum software (I’m assuming you are running vBulletin on Apache2 with
mod_php5). memcached is a daemon that can store objects in the system’s
memory (e.g. results of database queries) which can speed up your web
site tremendously. You can use memcached over a network (i.e., install
your web application on one server and memcached on another server),
but usually you install both on one server to avoid the networking
overhead.

This tutorial shows how you can set up a Linux Mint 6 (Felicia)
desktop that is a full-fledged replacement for a Windows desktop, i.e.
that has all the software that people need to do the things they do on
their Windows desktops. The advantages are clear: you get a secure
system without DRM restrictions that works even on old hardware, and
the best thing is: all software comes free of charge. Linux Mint 6 is a
Linux distribution based on Ubuntu 8.10 that has lots of packages in
its repositories (like multimedia codecs, Adobe Flash, Adobe Reader,
Skype, Google Earth, etc.) that are relatively hard to install on other
distributions; it therefore provides a user-friendly desktop experience
even for Linux newbies.

Linux has a special mount option for file systems called noatime. If this option is set for a file system in /etc/fstab, then reading accesses will no longer cause the atime
information (last access time - don’t mix this up with the last
modified time - if a file is changed, the modification date will still
be set) that is associated with a file to be updated (in reverse this
means that if noatime is not set, each read access will also result in a write operation). Therefore, using noatime can lead to significant performance gains.

This article describes how you can rebuild the Squid 2.6 package for Debian Etch with support for X-Forwarded-For
headers - this feature is not enabled in the default Debian Etch Squid
package. This feature is useful if you are using Squid as a reverse
proxy for your web site and are using a load balancer (such as HAProxy)
in front of Squid - it allows us to track the client’s original IP
address instead of the load balancer’s IP address (which to Squid
appears as the client).
