LTSP thin client tips

LTSP thin client tips

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).

Web of mistrust

Web of mistrust

You may have heard of the Web of Trust plugin for browsers.

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.

An air of thought

An air of thought

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.
