Self-hosting a distributed S3 compatible object store is just as horrible as it was 10 years ago. I feel we’ve made great strides on the database side, for example, but this is just as bad as it always was

The only fiber cable between Finland and Germany has suffered a cut last night. The cable mostly follows the Nord Stream routing in the bottom of the baltic sea.
The remaining links are mostly via Sweden.
I would expect this to hurt Hetzner the worst, since a lot of the workloads they host in Finland are here just for the cheap electricity but are actually connecting with clients elsewhere.
Must be weeks rather than days before this is fixed

Netflix can now serve 100Gbit/s of video (so something like 12,500 individual 4K streams) with an appliance using 100 watts of power. That’s 8 milliwatts for each 4K stream.
Remember that number the next time someone tells you that watching a Netflix show is as bad as driving an SUV or some shit.

oli itsellä tarkoitus tulla sillä työreissulta takaisin viime kuussa mutta Lyypekissä iski ahdistus ajatuksesta ja suuntasinkin sitten Köpikseen.
Voisin kuvitella että porukassa toi 1,5 vrk kelluntaa menee leppoisammin kuin yksin.
