 Hi, everybody. I'm Jen with opensource.com. I have a brand new top five articles of the week for you today, January 27th. At number five, Shell Scripting, an introduction to the SHIFT method and custom functions. In his first post on the subject, Getting Started with Shell Scripting, Seth Kinlon covered the basics. In this next article, he expands on the SHIFT method of parsing options and creating custom functions. At number four, Using R-Sync to back up your Linux system. Author David Booth says, without good backups and a well-planned backup policy in process, it is a near certainty that sooner or later some critical data will be irretrievably lost. At number three, Python and Successive Approximation. Greg Pittman shows us how to do Successive Approximation in Python with this example script. At number two, Brotli, a new compression algorithm for faster internet. Former OpenStack community manager Stefano Mifuli brings us this article. He says, while the Brotli algorithm was announced by Google in September 2015, only recently have the majority of web browsers adopted it. And finally, at number one, Solid State Drives in Linux, enabling trim for SSDs. In this article, learn how Solid State Drives differ from traditional hard drives and what it means for configuring your Linux system. And don't forget to enter our giveaway for a Lulzbot Mini 3D printer by January 29th.
