I’ve moved my desktop at home from a Windows XP to a Ubuntu Hardy Heron (8.04 – and soon the new Intrepid Ibex), and have had to google a bit to find the answers to my following “problems”.
Here are some of the issues I experienced, and some possible solutions (and as usual, there are several different solutions to each problem).
This list will get an update as soon as Ubuntu 8.10 goes live (which should be in a couple of days) – perhaps they even fixed a few of these little things. :-) Read more…

While IT professions are very interesting, they’re usually one of the hardest to explain (in your face, quantum physics!).
Questions such as “what is ‘routing’ ?“, “how do you write programs ?“, “Why do we need IPv6 ?“, “What’s a database ?“, “What is hosting?“, ”what do you do at work ?“ … are all easy to ask – but hard to answer to someone with little or no prior knowledge.
With that in mind, I’ll try to form an answer that most novices can understand, in an attempt to explain some of the most commonly asked IT questions. From simple subjects (such as the ones posted above), to more detailed topics like “deep packet inspection” and “virtualization”.
The first try-out will be: What is port-forwarding or routing?

With so many distributions of Linux out there, and each having its own method of identifying itself, it can get tricky to find out the Linux version you’re working on.
You can usually find out most of the information in the /etc/*release or /etc/*version files. If any of those files exist, you can cat them to find out its content – and to find out which distribution you’re running.
Here are a couple of examples. Read more…

It’s a security risk in most situations, but for a home network this can really be useful (where not every computer _needs_ a password). So, what to change to allow empty passwords to be entered when making a remote desktop connection to another computer/server? Read more…

It’s not as difficult as it might sound, so here’s the quick-n-dirty way of installing and compiling your very own PHP extensions/libraries, from the PHP source code. With a normal install, not every library is compiled and installed – so it might leave you with several functions that aren’t working.
In this case, I’ll assume you’re trying to compile the dBase-extension. It’ll probably start with the following error, shown on screen:
Fatal error: Call to undefined function dbase_create() in … on line …
It means the extension wasn’t loaded – and in most cases isn’t present on the server at all. So we’ll have to create it ourselves. Read more…
