I lost some time figuring out how to associate “.stl” extensions with Slic3r. Gnome wrote a good documentation but it is not obvious to find. I did not use the package manager for that because I wanted the up to date AppImage.

I recently wanted to setup a repository for some custom OpenWrt packages for Respeaker. It seems that it is not so well documented, or at least, I did not found it and I have been helped on OpenWrt forum. Also, it is better to sign packages so…here we go!

Thanks to Let’s Encrypt program, we can now generate free SSL certificates. I used the beta program with success, but now I want to use it on another server running through HAProxy. This is a trick to combine certificate, chain, and private key to be loaded by HAProxy :-)

I lost a few couples of minutes trying to figure out where and how rss2mail is storing its configuration files, as I did not find in the documentation.
rss2mail is a couple of Python scripts to parse an RSS feed and send new items to an email address. It is really convenient but configuring it to have HTML instead of plain text and to choose police is really better.
