Finally finished the recollection! Here's the list of talks I've done in the past five years (if I have found the corresponding slides).

I didn't know #twitch use #IRC for it's live chat services, nor that it was that easy to connect via #weechat. It's so nice to see a big name on the streaming industry using open technologies instead of some random, closed source, undocumented, propietary api. Good job twitch :)

Important: Let’s Encrypt will be revoking 3,048,289 TLS certificates tomorrow. To find out if your site is affected and what to do, see

The next two months will be quite interesting for . By measuring the hashrate drop we can probably estimate how much of it was dominated by ASICs.

Synapse v1.10.0 has landed, it contains an important cross-signing fix, as well as some anti-abuse measures. Checkout the blog post for more details

very good idea: creating a linux kernel module mastodon client, exposing the api via /dev/masto #mastodev

I always find it quite absurd that many blockchain people use centralised services so heavily. Twitter instead of Mastodon, Google Analytics instead of Matomo, just to name a few.

Too much crypto — many symmetric cryptography primitives would not be less safe with significantly fewer rounds.

PSA: Did someone link you a post somewhere else on the fediverse? Copy and paste it into the search bar, and you can read it all from the comfort of your client, and interact with things without dealing with the clunky "remote whatever" OAuth business!


“If I am proved correct, the Germans will call me a German, the Swiss will call me a Swiss citizen, and the French will call me a great scientist. If relativity is proved wrong, the French will call me a Swiss, the Swiss will call me a German, and the Germans will call me a Jew.” (Albert Einstein)

Have been trying out various monitoring solutions (InfluxDB, Elasticsearch) for my servers, and finally settled on Prometheus. The pull-based method seemed a little bit weird in the beginning, but the more I use it, the more I feel it's better.

@Rick_B_ I can't impose my will by design. Mastodon is open-source, anyone can run their own server (and 2,000+ people do). I can control my own server but if someone doesn't like it, they can leave and use a different one. Freedom of movement.

All server migrations are finished! The whole That World infrastructure is back online again.

"I use Linux as my operating system," I stated proudly to the unkempt, bearded man. He swiveled around in his desk chair with a devilish gleam in his eyes, ready to mansplain with extreme precision. "Actually," he said with a grin, "Linux is just the kernel. You use GNU+Linux!" I don't miss a beat and reply with a smirk: "I use Abyss, a distro that doesn't include the GNU coreutils, or any other GNU code. It's Linux, but not GNU+Linux."

The smile quickly drops from the man's face. His body began convulsing, he foamed at the mouth, and he dropped to the floor with a sickly thud. As he writhed around he screamed, "I-IT WAS COMPILED WITH GCC! THAT MEANS IT'S STILL GNU!" In a cool fashion, I replied "Abyss uses the LLVM compiler suite, GCC uninvolved."

With a sickly wheeze, the last of the man's life was ejected from his body. He lied on the floor, cold and limp. I've womansplained him to death.
