HowToMD5SUM When one has downloaded an ISO file for installing or trying Ubuntu, it is recommended to test that the file is correct and safe to use. The MD5 calculation gives a checksum (called a hash value), which must equal the MD5 value of a correct ISO. The program md5sum is designed to verify data integrity using the MD5 (Message-Digest algorithm 5) 128-bit cryptographic hash. MD5 hashes used properly can confirm both file integrity and authenticity. In terms of integrity, an MD5 hash comparison detects changes in files that would cause errors. The possibility of changes (errors) is proportional to the size of the file; the possibility of errors increase as the file becomes larger. In terms of security, cryptographic hashes such as MD5 allow for authentication of data obtained from insecure mirrors. While security flaws in the MD5 algorithm have been uncovered, MD5 hashes are still useful when you trust the organization that produces them. Check the iso file Manual method Semi-automatic method

My Effort at Writing Help for Unity I told the kind folks in #ubuntu-doc that I'd give it go, writing up some documentation for Unity. Here's a first draft of my best effort. I'm hopeful that the real pros at this can mine this material for making nice official documentation. I'm hoping that thay can cut and paste from here into their docs, or at least can edit the content to something they like, but maybe get going a little faster since there is something to change, rather than having to start fresh. I don't believe myself to be a particularly good writer, but, here without further a do ...

Ubuntu 11.04 (Natty Narwhal), Reviewed In Depth : Introduction Ubuntu 11.04 (Natty Narwhal) has arrived, and we have the scoop on everything you need to know about Canonical's latest Linux, along with the usual review and benchmarks. Is this the change we've been waiting for, or is the Natty Narwhal a fail whale? A couple of weeks ago, Canonical, the company behind Ubuntu, launched Ubuntu 11.04 'Natty Narwhal', one of the most highly anticipated and controversial desktop Linux distributions ever introduced. What makes Natty a landmark release is the inclusion of the brand new Canonical-developed Unity user interface. Unity replaces the GNOME 2 shell that served as Ubuntu's default UI since the distribution's inception. The timing of Canonical's decision polarized both the Ubuntu and GNOME communities, as the GNOME project also recently finalized GNOME 3. As the most widely-used desktop Linux distribution, Ubuntu was a major driving force behind GNOME's adoption. Let's start with the meaning of Natty. And for that matter, what is a narwhal?

How to Get Help With a Command from the Linux Terminal: 8 Tricks for Beginners & Pros Alike Whether you’re an inexperienced terminal user or a grizzled veteran, you won’t always know the right thing to type into the Linux terminal.
