With all of the new changes coming to Ubuntu I assume many users will be considering new window managers or different distributions altogether, so I decided to review some of the choices available.

This article explains how to install Zimbra Collaboration Suite 7 (ZCS) on CentOS 5.x (64Bit). Zimbra is a collaboration suite very widely used in the world. Users can share folders, contacts, schedules and other things, using a very rich web interface. One important note is that we're using CentOS 5 64bits, that is not oficially supported by Zimbra team (only RHEL and SUSE are). But CentOS works fine with Zimbra.

WriteType 1.2.130 is now available! WriteType is a word-processor designed for schools to help young students write better. It gives students who have a hard time writing an easier approach in putting their ideas on paper. The new release makes it even easier for students to succeed!

When you need to make additional tests after a false conclusion you can use if then elif statements for more options. The provides a way to create more intelligent statements.

It's just not open-source graphics programs dropping new releases this week like GIMP and Blender, but in the open-source audio editing scene there's also work taking place. The Audacity team just released version 1.3.3 of their popular audio editing application...

Acrosser announced another entry in its line of fanless vehicle PCs, this time featuring Intel's D425 or D525 Atoms. The AR-V6002FL includes CAN bus support, four serial ports, a 2.5-inch drive bay and CompactFlash slot, two Mini PCI Express slots, and an optional GPS receiver, according to the company....

Unity got its notification area (called Systray by the Ubuntu developers) back a while ago, but only for a few applications: Java apps, Mumble, Wine applications, Skype, and hp-systray. But there's an easy way to either re-enable the Systray for all applications or to whitelist a few applications you can't live without. Read on!

April in Linux land means most people are going Ubuntu crazy as Canonical's first bi-annual release of the year comes to term. I would like to take a moment to remind everyone to stop and smell the distros. Even in April there is much more to Linux than just Debian's child (and grand-children).

One of the other "big names" in the Linux world is Red Hat's community driven Fedora.

If you've been using Linux a while, you probably have some finely tuned configuration files for Bash, Vim, Emacs, or other applications. Keeping track of those files manually, and copying them to other machines when you set up new systems, can be a pain. Take control of your config files on Linux by using git to track changes and move your configs to new systems.

If we were already talking to our computers, etc. as we should be, I wouldn’t feel a need to write this to you. Given current rates of adoption, Linux still seems a generation away from being the priceless piece of free software useful to every child and PhD. This army your kernel enables has millions of people, but they often lose to smaller proprietary armies, because they are working inefficiently. My mail one year ago listed the biggest workitems, but I realize now I should have focused on one. In a sentence, I have discovered that we need GC lingua franca(s).

WordPress is quick and easy to install and update, but the quicker you can make these operations the better, right? If you have shell access to the server where your WordPress copy is installed, it is possible to make some operations much quicker and safer with this shell script.

When it comes to Linux virtualization, QEMU is one of the common parts of the virtualization stack. It's a very common emulator that provides dynamic binary translation and can run many unmodified guest operating systems on many different architectures from x86_64 to MIPS and PowerPC...

Today, i’ll show you how to use knockd to improve the security of your linux server, the more common use that i’ve saw so far is: “i’d like to connect on port 22 (ssh) but i don’t want to leave to port open for everyone..and i’ve a dynamic IP”. In these cases you can close the ports and use knockd to knock on the ports of your Linux box and let you in.

Let me start at the beginning: Recently, pulseaudio not only switched to a more power efficient (and otherwise) timing system. It also provided the infrastructure to use ALSA devices without causing _any_ interrupts, so you CPU can stay longer in standby mode, saving you power and avoiding playback glitches. With kernel 2.6.38 the first driver supports this infrastructure, the snd-hda-intel driver. This is what I tested for power efficiency in this article...

This week's links include how to make the transition to agile programming, how to build a strong applications security framework and a very funny cartoon on feature creep.

the Dbmail system stores email into a relational database: how and why Harald and his company use Dbmail is really interesting. Here’s the story:

When the "Save as WWF" campaign was launched, WWF Germany created a Facebook page. I guess they never expected that it would cause so much controversy, because initially critics could vent their objections freely and add all the links and pictures they wanted. Being one of the opponents in that controversy myself I was about to experience their social media tactics first hand. This is my story.

Yesterday when I introduced Plasma Active, I secretly thought to myself "oh no, so it's begun." See, I have this underlying fear that KDE is going to go the way of GNOME 3 and Unity and finding the removal of user choice in upcoming KDE software compilations sowed the seeds. Despite my biased first impressions, I booted the live ISO provided by open-six. open-six used openSUSE as the basis for it's live CD. It was a bit slow to boot, but truthfully, I didn't really expect it to finish. Afterall, the list of known working devices is short and I was booting on my regular desktop machine with NVIDIA graphics and two monitors. Well, it did finish booting and it even started the Plasma Active desktop. (The desktop was cloned across the two monitors - which is really best-case scenario without proprietary graphic drivers.) And darn it all, I really hate to admit this... but my first word, my first thought was, "Wow!" This Plasma Active thing might really be cool on a little netbook or tablet.

Habey announced an EPIC-format SBC (single board computer) that features a 1.1GHz Intel Atom Z510P processor, 512MB of onboard memory, plus PC/104, PCI, and Mini PCI expansion. The EMB-4650 also includes CompactFlash and SD slots, dual video outputs, and eight USB 2.0 ports, according to the company....

Following last week's release of the stable Wine 1.2.3, it's now time for a new development snapshot of Wine 1.3. The Wine 1.3.18 is a particularly interesting release since it finally takes advantage of raw mouse events with X Input 2...
