Well written, but I do not understand why this is news. A thread will deadlock if asked to wait on itself, and that generalizes to any fixed size group of threads. That seems like it should be obvious to everyone. The standard guidance of a

Wow, really? Then what’s the point of memory mapping in the fist place? Or do they suggest manual flush/sync actions for persistence.

Then how was the Asahi team able to load their own firmware? I was concerned about that process--whatever it is--being something apple might lock down. If it's already likely locked down to Apple's satisfaction, that's good n

It’s the difference between “there’s no published standards other than the reference implementation for some of the API” and “there’s no published standards and extremely monolithic reference implementation design coupled to proprietary b

EKS can get pretty damn big, well into the thousands of nodes without much special tuning, and beyond that with some care and control plane monitoring. Expensive, though.

I think you’re arguing against a point that GP didn’t make. Optionality and empty/uninitialized references can both be encoded in a type system, or one, or the other. I didn’t interpret GP as arguing for or against null or otherwise re

Thanks to the advice of a colleague who had studied control theory, I once used PID controllers to manage autoscaling compute resources downstream of a lot of message queues. We used plenty of more typical autoscaling systems too, but for s

The AUR is not the Arch package manager or repository . The main Arch package repos are managed similarly to Debian, or Fedora, or whatever--caveat Arch's nature as a rolling release, but in terms of vetting and ownership/securit

They might well do that, but that takes a lot of time and money to implement, meaning that the government’s goal of causing them immediate pain for minimal effort is still achieved. It’s likely a better use of anthropic’s resources to try t

I don’t think that’s accurate. Export control is a total ban, for 350 million citizens and everyone else, just via a legal technicality/exploit. All of the government’s options to retire/ban Fable entirely would have required ex

The linked article discusses very different reasons for preferring kube. CTOs and hiring managers like it for reasons totally different from the cargo cult/hype-driven engineers.

Spot on. I have a lot of trouble convincing cloud folks that for durable state, you probably don’t want kubernetes. It’s not that e.g. the CSI drivers and operators for clustered databases aren’t top notch—they are; the era of “avoid stat

Is it analogous to portainer with a git-pull-compose-apply loop?

Kind of. Those exist, but because Linux’s formal ABI is syscalls and not libraries that combine them in known-safe ways, the clone speedups that make fork faster are a confusing and fragile API for low-level programmers to use. That, and ev

Eh, that argument works on any claim and is nonfalsifiable-ish, so I think it can be ignored. People buying more chocolate ice cream than vanilla? Could be changing preferences or Hersheys marketing, or it could be undetected brain worms. P

Not the case; good abstractions are valuable, but the performance differences between runtimes are very real. Take the example of some simple HTTP<->blob store service gets slammed with millions of requests when someone using the API
