A circular buffer is a really cool fixed-sized FIFO data-structure useful when passing a stream of data from a 'producer' and 'consumer' thread.

Linux offers all the tools needed to diagnose and recover data for free from a failing hard drive as long as it can still be read. I'm just going to cover in a general way some tooling options to repair or extract data on a problematic hard drive in this post.

For those who cannot be bothered to roll out their own custom recovery image, System rescue CD has most of the needed tools within. To note that there are other equally capable custom distros images available for this very purpose. A spare USB key with at least enough storage to hold the distro's image and a quick use of dd is all that required get going.

The official french government page for the coronavirus is a good place to keep informed but (a) it's long and (b) doesn't indicate what exactly has changed... So I wrote this little shell script (BASH) to fetch the page and the 2 forms that are required when going outside lest you end up with a rather hefty fine. The script just compares the HTML and the txt version of the forms with any previously downloaded ones and signals if there are any changes between the two versions.

Although a little intimidating for the beginner, the command line on Linux brings at your fingertips a cornucopia of powerful tools allowing operators endless ways to deal with computing related problems.
