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, it's an efficient design). What it does mea

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 assemblies too (beyond the duplex patches which is basically th

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

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 beaten path for headscale.

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 signaling what they think the expected use of headscale is.

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) is too horrifying to contemplate

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 similar for these human evaluations, rat

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 high-powered beam of light is mixed with the input signal us

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 for a couple of years, but zero guarantees that it would last

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 scale discussed here, there are no free lunches.

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 the end in the early 2000s, and that business wasn&#x27

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 Concorde—they didn't, Concorde had very health

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 vision stuff using Apple’s Vision framework. No complaint

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 flows off-app, Apple forbids offering IAP in the sam

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 off it’s game over for remote access.

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 wondering whether a headless-oriented SKU wouldn'

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

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)

I’m just getting the default route from both upstream routers. They’re not diverse in terms of the internet routes they have, this is just for HA.

I rent a single ~600 meter fiber that connects my home to the network infrastructure of the company I run. The rent is $75/mo or so. I have passive CWDM muxes on the line to run two 10G connections to two separate edge routers. My home

These were HTTP/2 requests, not connections, so no per-request TCP negotiation. I'd say it's very easy to generate a huge number of requests like this, even if it's over TLS.

I've been trying to shoehorn mTLS into existing infrastructure of Postgres clients and servers. This would be trivial if Postgres used straight-up TLS; as it is, though, you need sidecars that understand the Postgres wire protocol and

I vividly remember how Ari Vatanen won the 1987 event in a Peugeot 205 (I was in elementary school). On the heels of the rally success he went on to become the PR face of Big Milk for the next decade or so.
