Go's http.Client will keepalive a TCP/TLS connection to save you handshake latency on second requests. But it can only do this if you completely finish reading the last request. No…

Automatically draining http response bodies is a risky silent behaviour change. I think it will be an improvement for most applications, but it's very subtle if you were relying on…

The really big thing is the model weights, which are a read workload not a write one, it won't affect an SSD's write endurance. The write workloads are just the context and any K/V…

Standard llama.cpp can mmap the gguf, so it'll stay on disk if it doesn't fit on memory, and the kernel page cache will ensure the hot parts ("resident trunk") stay resident. What'…

Linus Torvalds said last week that LLMs were just a tool. Lorenzo Stoakes had the impeccable rebuttal that "it's a tool in the same way a nuclear bomb is just a tool" - of course i…

This distinction is less a gotcha and more actually immediately obvious in the Windows task manager. It shows cached memory separately and in a different colour. The "in use" part …

Steve Yegge calls this is the "discernment horizon" - https://steve-yegge.medium.com/the-flat-curve-society-36c8b0...

The off-the-shelf player in this space (structured red-team search) is probably https://github.com/usestrix/strix (no affiliation). But any frontier model, if you tell it "here's h…

Blender has all these curve tools and more, it might be interesting to write an exporter to the Neverball file format if one doesn't exist yet.

In my harness i implemented apply_patch just taking unified diffs for patch -p1. I was shocked to see how bad models are at generating them. I started logging diff failures to anal…

There was some earlier speculation this is the model behind the stealth-released openrouter/owl-alpha model, that's been free for the last month.

There's also this new one: https://github.com/joske/yserver

It was somewhat slow about a decade ago - you can see - (2015, Go 1.5) Calls cost about 170ns https://www.cockroachlabs.com/blog/the-cost-and-complexity-o... - (2017, Go 1.8) Cgo s…

Cgo is cheap these days, don't worry about it. It's barely more expensive than a direct function call but, not so you'd notice unless it's in a hot loop. At which point the lack of…

This is all true but is a somewhat Java-flavoured perspective i.e. generations ties you into a moving collector, which ties you into barriers and complicates FFI, which is not alwa…

Hold on - 15k GBP? An ordinary heatpump for an ordinary house should cost something like 3000 NZD including labor for installation. What are we doing differently?

Long time Ars reader, looking forward to your article (and have a few DOS games to reverse in mind already)! Is this with a Ghidra MCP or some other technique? And why two models -…

I'm running Qwen3.6-35B-A3B on a very ordinary desktop PC (32GB DDR5, 8GB Radeon 6600XT) and getting a useful 15-20 tok/sec out of it. The MoE architecture and auto offloading from…

I used to love Descent 2! People say this a lot about Linux and it somewhat rubs me the wrong way - sure, the Windows binary works if you install its library dependencies (wine). L…

Syscalls on macOS aren't guaranteed to be stable - Go found out the hard way and in 1.12 they changed to call libSystem.dylib instead. In general, stable syscall numbers are just a…

I was pleasantly surprised to learn the architecture for this - a minimal backend that does a PAM auth and gives you a shell over websocket, with only your own Linux user credentia…

Intel Ispc is a compiler for a C superset language that targets CPU SIMD and GPUs.

This is not true - it's actually all the same VM if you check hcsdiag. WSL2 distros only use Linux namespaces, same as docker, and the WSL2 --system distro can see PIDs from all ru…
