Crash is the best-case outcome for a browser bit flip. Here's bitsquatting: https://ripe92.ripe.net/programme/meeting-plan/sessions/112/...

If you see photos/videos of Hetzner datacenters, their servers are essentially plain, low-end motherboards (1G network, few slots) sitting on shelves (don't mean that as derogatory…

LC connectors are smaller and what the actual SFP+ modules typically have. If you want to run a link with just one fiber, you need BiDi optics. FS does custom multi-fiber cable ass…

There’s nothing hard about it if you can run pre-terminated patches. Which you typically can since the connectors are so small.

What a blast from the past. I added that!

TIL! My problem with them requiring sqlite was that I assumed it would make a high availability setup either hard or impossible. Maybe that's not true, but definitely off the beate…

Apparently they've deprecated Postgres support and now only recommend sqlite as the storage backend. I have nothing against sqlite but to me this looks like Tailscale actively sign…

Just had my first uncorrectable memory read error on our servers in 10 years or so today (in Sacramento). I'd like to think it's related because the alternative (buying new DIMMs) …

In the performance tests they said they used "consensus among 64 samples" and "re-ranking 1000 samples with a learned scoring function" for the best results. If they did something …

From the PostgreSQL 17 Beta 1 announcement: > PostgreSQL 17 adds a new connection parameter, sslnegotiation, which allows PostgreSQL to perform direct TLS handshakes when using ALP…

They’re probably amplifiers rather than repeaters. Optical amplifiers don’t need to decode the signal to work. Here’s Wikipedia on erbium-doped fiber amplifiers: > A relatively hig…

I moved away from Cloudflare—to self hosting our network infrastructure—because, while this didn’t happen to us, I was very aware that it could. We had a great deal on Enterprise f…

Do you mean to imply that cloud services at higher levels of abstraction are cheaper per unit of compute than simple VMs? I believe you’ll find that the opposite is true. At the sc…

Not really, because Concorde died in the seventies when the lie flat business seat didn't exist. BA and AF managed to keep the zombie fleet going very profitably all the way until …

Not sure why you're getting downvoted, this was definitely a key factor that made Concorde into a niche product. It's not that customers preferred slower and cheaper flights over C…

If you need macOS on the server for whatever reason, your only option is the Mac. I have four Mac minis racked up for this, with two use cases: 1) iOS CI/CD and 2) some computer vi…

Apple's policies for external purchases are hilarous. The only goal is to be punitive. For the External Link Account Entitlement that "reader” apps can use to link to purchase flow…

I think the crucial flaw here for the IPMI/BMC access use case is the fact that the card requires the server to be powered on to function. So if you accidentally turn the server of…

Torment Nexus?

The idea that even 10-20% of users would power their Pis with PoE seems wild to me. Seems like a much smaller niche to me (even though I'm one of those people). Anyway, I have been…

I'm absolutely 100% certain that AWS (for example) wouldn't do that for you with the instance types that feature direct attached storage.

The Moon being a great example.

Have they, though, if marked to market? After the deposit outflows this week?

Both of the upstream routers are mine, there’s no difference to the routes they have available. (They’re connected both to Tier 1 transit as well as the major local IXP)
