Understanding in Practice: DMVPN and Per-Tunnel QoS

In preparation for the launch of the 'Network Engineer' course, we have prepared a translation of some interesting material. There's one remarkable thing about DMVPN that I encountered some time ago: DMVPN Per-Tunnel QoS. Obviously, I’m not the only one (as a lab rat) who thinks this is cool. Every time I show this to people, I see their eyes light up — a consequence […]

Update of the Thunderbird email client 78.2.1

And even if you’re not by the campfire, we have a story for you. A story about how we started working with the storage on Tarantool. Once upon a time in […]

A font has been released that automatically censors offensive expressions

The Finnish company TietoEVRY has released a TTF font called "The Polite Type," which turns offensive English expressions, as deemed by the authors, into ligatures, replacing them with neutral expressions or blurred spots. Naturally, if you add the character 200C or 200B (zero width non-joiner or zero width space) and even an extra space or change the case, the censorship doesn’t activate. The font is declared "open-source," […]
