Welcome to cron.weekly issue #56 for Sunday, November 27th, 2016.

It’s been a little over a year since I started cron.weekly, I totally missed the anniversary a few weeks ago. Either way, happy 1st birthday cron.weekly!

There’s plenty of variation in this weeks’ content too, from interesting projects to guides, news about Debian planning to remove ye old /usr/bin split, Fedora 25 is out, …

Grab a coffee and enjoy your Sunday read!

News

Debian considers putting everything in /usr

It was already rumoured in January of this year that Debian might be saying farewell to the /bin vs. /usr/bin split. Instead, the idea is to have things like /bin and /sbin be symlinks to /usr/bin and /usr/sbin, doing away with the split place for binaries.

This weeks’ Humble Bundle is especially interesting: for 15$ you can buy 16 Linux and open source related ebooks, from shell scripting to network troubleshooting to learning about sed & awk.
