If you're focused on lightweight, native and fast, I don't think you should use an immediate-mode GUI toolkit. Why does an app like this need to hit a 60fps framerate? It's not a game.

I have no skin in this game, but just because they're doing it doesn't mean it's their focus, the EU is big enough to work on multiple 0.8%-size wins all over the place.

I'm not sure this is a real problem - for embedded you know a priori - for arbitrary desktop/SBC machines, misa will be available in kernel mode and /proc/cpuinfo will be available in user mode.

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. Now in 1.27: > http.Response.Body drains itself o

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 old behaviour

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 cache - llama.cpp does not mmap those to dis

by mappu 2mo ago
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's the benefit of a custom implement

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 it's useful but there is clearly more to

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 is real in-use excluding the page cache. On my cur

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 analyse - - All models are terrible at generating line numbers f

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.

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 speedup by 50% https://go.de

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 cross-language inlining is your real pr

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 always the right tradeoff. A non-fragmenting allocator goes a lo

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 - did you try using Qwen3.6-35B-A3B for everything? (Or 27B o

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 system to VRAM is just fantastic. Unsloth Q4_K_XL

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). Likewise (OK, ever since libc5/glibc2 changeover in 2001

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 Linux thing. Everyone else uses blessed system librari
