No it’s not open source but it is available for both Linux and Windows.
IncentivesPro make a product I recently used for a Virtual Desktop Thin Client Implementation. That is USB Redirection for Remote Desktop. It uses a proprietary client/server and so I used Windows XP embedded thin clients to redirect specialised USB Thermal Laser Printers to the Vista Virtual Machines. The website looks a bit underwhelming but the product is flawless and it’s priced much better than their competitors. If you have more time than I did, it’s likely you …

mod_rewrite is a powerful Apache module that gives you the power over the URL’s displayed to your visitors to your site.
Much has been written already by many people using both examples and tutorials of the basics. The aim of my addition, as always is primarily for my own notes and secondarily to explain why you want to use mod_rewrite for SEO ranking retention.
Let’s say you have a website that enjoys well ranked pages and a lot of traffic via google or has a great deal of Backlinks from other …

Interesting OSS links: Skype for Asterix / Wavemaker / AccountLabPlus

Haven’t had much time to go into detail with these but I think it’s worthy to take note of them
Skype for Asterisk has been released at last.

A new Skype for Linux Beta 2.1.047 has been released which fixes CPU problems with new PulseAudio and works brilliantly and also adds SMS support.
Also, I came across a very Rapid Application framework for building Ajax web apps called Wavemaker. They have an open source version and an Enterprise Version. Watch one of the videos where he builds a searchable client database in …

netboot.me is a service that allows you to boot nearly any operating system or utility on any computer with a wired internet connection – without having to know ahead of time what you’ll want to boot.
netboot.me works through the magic of netbooting over http. There are a number of ways to boot a computer with netboot.me. The simplest is to download a bootable image, which is 626Kb and burn it to a CD or put it on a USB memory stick, or floppy disk. Boot off it on any networked …

I have previously written about Tilda, a gnome replacement for Yakuake. I had some issues with Tilda so I came to have a nice relationship with Yakauke. It’s important to note though, that there is another reasonable alternative to both Tilda and Yakuake and it’s called Guake.
Guake has some of the basic features of Yakuake but is still lacking in a few things. The main ones for me are:

Yakauke allows you to choose terminal width / Guake takes up fullscreen width. The advantage of this for me is that I …

Chromium is the open source version of Google Chrome for Linux. It’s still in alpha stage but it’s been very stable for me. The biggest downside is lack of Flash support for things like Google Analytics and Youtube.

For Ubuntu, install Chromium like so:

echo “deb http://ppa.launchpad.net/chromium-daily/ppa/ubuntu jaunty main #chromium-browser” > /etc/apt/sources.list.d/chromium.list
sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com 0xfbef0d696de1c72ba5a835fe5a9bf3bb4e5e17b5
sudo apt-get update && sudo apt-get install chromium-browser

to get Flash working:

cd /usr/lib/chromium-browser/plugins
sudo ln -s ../../flashplugin-installer/libflashplayer.so

Screenshot running on 64bit Ubuntu Jaunty Jackalope. Watching this was consuming approx 25% cpu in a single chromium process instance:

I am …

Today, I came across a document where I had to type a degree symbol in Linux. Thanks to this post at Arch Linux Forums, it was painless to find out how. So here it is:
In windows, apparently you hold down Alt+0176.
Linux is different and to achieve the same, hold down Ctrl+Shift and type u+00b0, though if you are writing for html, the correct symbol is
°
Alternatively you can copy and paste it from this table on wikipedia, which includes other useful symbols like Pound, Registered and Copyright.
It will actually type the …

Pluf is a PHP Framework developed as a port of Django to PHP. It claims to be simple, elegant and easy for people used to Django but in PHP5 so easy to deploy all over the world.
After reading the documentation, the file layout and concepts are all quite similar to django, though a downside is that we lose much of the beauty of the Python language and it doesn’t seem to have the Admin interface that makes django so delightful to work with.
Here is a sample of a helloworld, which …

So, you have used Website Optimization Analyzer or you installed Yslow for Firefox or you discovered somewhere else that compressing your files (html, javascript & css) is a good thing to do. Unfortunately, it’s not always as easy as it looks to do this.
In Apache web hosting environments, there is a module called mod_deflate (for 2.x versions) or mod_gzip (for 1.3) versions. This is generally the easiest way to get content compressed. As in my last post about Magento, you should normally be able to enable this safely with the …
