Coming Soon - London Ontario Linux User's Group - lolug.ca

I've just purchased lolug.ca! I will be setting up a community site, in the hopes that I can help to stir up interest in the community. When I first started using Linux, I had a free domain at londonlinux.ath.cx, but it wasn't a good domain name. I also didn't do much with it, so despite having people sign up, it languished and eventually I shut it down.

There has been a Google Group for lolug for years, but it seems to now be inactive, and the "website" for lolug which was at Vox (free service) is now gone, as is Vox.

Disqus seems to be taking longer than usual. Reload?

I use Disqus comments on this site, and I just had a problem where I kept getting the error "Disqus seems to be taking longer than usual. Reload?" with no comments or text entry box. I'm using Firefox 16.0.2, and I don't have any extra plugins enabled. A few are installed, but only the defaults are on. I read on the Disqus forum that it could be because of too many plugins (not here), slow internet (definitely not here!), and slow webserver (not here). The only other possibility, which is what I discovered was my problem, is a corrupted Firefox profile.

Samsung Galaxy S3 Mini - Rumour or Fact?

Rumours on the net are hinting at another Samsung Galaxy S III, but this time it's a mini! Nothing has been released officially, but there has been a sighting of a flyer in Germany that is hinting at a new unveiling, and the image on the flier is of the most recent Samsung release, the S III. Apple fanboys (and girls) have been going nuts, claiming that the only advantage to the S III over the iPhone5 is the larger screen size, and so this new release doesn't make sense to them. I think the concept that is foreign to iPhone users is one of choice.

Are You Searching From UWO Wireless?

Most people by now have heard of sidejacking. That's where a bad person (and a laptop) connect to one of the unencrypted wireless access points at school, and listen for the cookies of other students who are also connected and browsing the web. It's trivial to accomplish, and there is no easy way to detect it. It has been publicized as being the method used to hack your facebook or email. This hack can easily lead to partial or full identity theft.

About Ubuntu Operating System (What is Ubuntu?)

So you've heard about Ubuntu, and you'd like to know more? You've come to the right place. If you're looking for a tutorial, or a getting started guide, I would suggest refining your search, as there are plenty of places with that kind of information. This bit is only going to try to answer the question, "What is Ubuntu?".

First, a bit of background.

How Not To Pick Variables

Here is a small example showing how choosing good variable names can make a huge difference. Look at the following code block, and see how long it takes you to work out what it does. If you find it takes you a while, look at the improved code below that and see how much easier it is! Even with short variables that are words, not being descriptive makes debugging very difficult. Using letters on their own is frequently worse. Both code blocks are functionally identical, only variable names are changed.
