Thin clients are a great way to repurpose older PCs or get cheaper systems and still get a powerful network of workstations for schools or institutions with many different cubicles/offices for a fraction of the cost, both in cash, time and staff invested in its deploying and maintenance. However, just like any other computer, there are details that have to be worked out here and there. Tonight I'll give a tip about a particular implementation: LTSP plus Windows virtual machines with concurrent sessions over RDP (tested with Ubuntu 12.04 as a base OS and Windows 7 Ultimate as guest OS under Virtualbox).

You may have heard of the Web of Trust plugin for browsers. This product is marketed as a "Safe Browsing Tool", and supposedly improves the security of the web by allowing users to view the rating of a site before even clicking on it (as it places an icon next to all links), as well as other measures such as an icon next to the address bar, and a popup warning you if you try to visit a site that does not have a good rating.
It's been a long time since I've posted anything here. We've been busy - and perhaps I've been playing a bit too much Guild Wars 2. ;)
Recently I added a third screen to my system, and this only made the existing multi-screen issues I had with KDE even worse. Finally, I decided to do something about it, hunting down each issue one by one and fixing it. This post is just to serve as a guide to fixing these problems.
Error handling is serious business. Or at least, this is how a lot of programmers see it. For decades, programmers have handled program errors in a wide variety of ways, from error levels, to error codes, macros, exceptions and beyond, all based upon the core concept of detecting an error and then handling it. But this process may be inherently flawed, because it is a reactive, not proactive formula that ultimately places a huge burden on software design.
Dust is always a problem with electronics, and well, life in general. But most importantly, its a problem with computers. I've tried various means to stop dust from entering my home, including a HEPA filter and always keeping my air conditioner circulating the air, but nothing works quite well enough. Eventually I came to the conclusion that you have to tackle dust at the computer-level, and for that people resort to a variety of air filters.
