Securing a QNAP NAS

I recently bought a new NAS, after my old one turned ten. I am very satisfied with the reliability of my old QNAP which is still supported with software updates. This makes me a happy customer, and so I did not see any reason to switch brands. After initial setup (networking, firmware update, disabling most services) I did not get around to finishing its setup for a few days. It basically sat there from late May 2020 to early July 2020.

The state of the Ruby ecosystem on Windows

It’s not really a secret that Ruby is not best friends with Windows. You often encounter gems that just won’t install or if they install, will not run as expected. Among those gems are mysql, eventmachine, nokogiri or, in my latest project, curb. I think this could be improved a lot with just a few changes.
