Practices and expectations that one may have developed in working with conventional software licensing may lead to frustration when confronting open source software. The modest request, "Please, just show me the license" may be met with an unsatisfying response. While sometimes the response is very simple, often, the license information for open source software is more complicated and does not match the expectations set by conventional software licensing.

If you're on an email discussion group long enough, at some point, you'll see an email from a list member asking to be unsubscribed. Typically, at least 10 other people on the list will respond with instructions on how to unsubscribe, and those 10 responses will be answered by 10 more people confirming or commenting on the instructions. That's a lot of traffic to a mailing list just so one person can unsubscribe.

PERL is the go-to tool for many sysadmins who need something more powerful than sed or awk when writing complex parsing and automation scripts. It has a somewhat high learning curve due to its dense notation. But a recent survey indicates that PERL developers earn 54 per cent more than the average developer so it may still be a worthwhile language to learn. Read on for a demonstration of PERL using the popular strategy game Tic-Tac-Toe.

Here's the scenario: Whenever I need some source code or a bundle of art assets or a game from the internet, I download it to my ~/Downloads directory, navigate to the folder, and promptly realize I forgot the file name. It's not that I don't remember what I downloaded; it's the proliferation of file types that throws me off. Was it a tarball or a ZIP file? What was the version number? Have I downloaded a copy before? read more
