PortableApps.com founder John T. Haller has announced that his site for portable applications has reached its 100 millionth download milestone. PortableApps.com allows users to easily install various popular open source applications to a USB flash drive or external hard drive. Once installed, the applications can run completely from the drive and be used on any Windows computer.

The best program I found for doing this was PortableApps, free software that packs a suite of open source applications—including OpenOffice—into a handy menu that runs straight off any USB flash drive.

Not so long ago I was telling you about the new version 2 of Cairo Dock which was at the time still in beta/rc and that it doesn't look at all like the old 1 branch - this new version is by far the best dock menu application I've seen for any operating system.

A few days ago, version 2.0.0 full was released.

Beta 2 was released six days ago. I installed it yesterday on a spare drive in my secondary desktop system to check it out. The test hardware is an HP rp5700 Core 2 Duo with 6GB RAM; I installed the 64-bit version of the beta.

CodeWeavers has posted the first beta of CrossOver Games 8.1.0, a significant update to the company's virtualization software.

If you want to put a boatload of useful open source applications on a computer or, as I do, on a pocket USB drive so that you can have them with you at all times, there are now some very fast ways to do this. MacLibre is a great way to get tons of good free, open source apps in one download for Mac users.

The Joomla! developers have released a beta of version 1.6 of their PHP-based open source content management system (CMS) adding a new access control system and one-click extension updates

Today Mozilla released the third beta for the next major Firefox update, version 3.1. Firefox 3.1, which will likely be re-numbered to Firefox 3.5, will have one more beta before the final release this summer.

This article explains how to move a full profile (addons, themes, cookies, browsing history, passwords and so on) from Firefox 3.0.x to Firefox 3.1.x beta or any other version, but it also works for synchronizing Firefox on 2 different computers or backing up a full profile of Firefox.
