I already knew that the CCS EV car charging standard basically does IPv6 over powerline ethernet and uses something like SOAP calls for the charging negotiation.What I did not know is that the spec also allows the charger offer the car internet access via the charging connector! I’m sure all cars have a robust firewall in place…

@feld I was 👉👈 this close to getting an m.2 ethernet card to solve a problem I thought was with a Realtek NIC on a Minisforum motherboard. Was something else, luckily.

@futurebird @GottaLaff newspapers often have automatic a/b testing of online headlines—they write a bunch and the system converges on the one that gets the most rage-clicks

With the latest Bezos fuckery it’s a good time to commit to finally getting our AWS spend down to zero. We’re about two thirds of the way there but still paying AWS more than $3,000/month—three grand more than anyone should

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 fixedhttps://status.hetzner.com/incident/ec8a2f28-e964-46cb-94fa-bb4629c19777https://www.cinia.fi/en/news/a-fault-in-the-cinia-c-lion1-submarine-cable-between-finland-and-germany

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

Ceph: do you have a Ph.D. In Ceph? If yes, it’s greatMinio: bad performance (each object is a minimum of two files on disk but typically more like 16) combined with weird requirements like a minimum of four servers that have an identical set of disks. Replication between clusters is best effort onlySeaweedFS: great in theory, not trustworthy in practice (especially on the filer layer)Deuxfleurs Garage: “you should make periodic snapshots of the metadata database to survive crashes”

Pretty impressed with Garage so far, after trying literally every other self-hosted S3 alternative

Reasons I'm behind the curve here:- Originally the Garage docs seemed to indicate that you *needed* exactly three data centers. The docs are improved but more importantly the garage cli itself makes it very clear what kind of durability/availability you're getting with a planned server layout.- The docs have a scary section about the default LMDB metadata store easily losing data, along with instructions on how to mitigate with snapshots etc. It doesn't mention that replication solves this!

A fiber cut between Turku and Korppoo this morning, eyeballing it I'd say at 7:12:27 AM local time. Pretty sure no shadow fleet in these waters 😅

“According to our provider, there is a delay in the field engineer's ETA due to staffing shortages at their supplier.”my experience is that SLAs are worthless nearly always

1. An SLA will not make the service work better2. An SLA is unlikely to make repairs faster3. Any service credit you're owed due to an SLA failure will definitely not cover the premium you've paid for said SLA

@wolf480pl a better mental model is that it's shitty insurance with high premiums and small payouts.in an ideal world a provider would figure out what kind of service level they are able to provide and then that's the SLA, but a more realistic picture of the real world is that the SLA is what customers want it to be and infra/ops will not get a say in whether that's something they can deliver

@ignaloidas @whitequark @q3k well, Mellanox NICs offer regexp acceleration today and I’m not sure this is the preferrable outcome
