It also isn't a unique thing. See (for example) the entire history of, well, pretty much any country. There is a reason Utopia literally means "no place". * Genocide of the natives? Literally all countries in the Americas,

Pretty sure it is sexually transmissible, so I would not be too sure about that.

Same. Opencode + oMLX (0.3.4) + unsloth-Qwen3-Coder-Next-mlx-8bit on my M5 Max w 128GB is the sweet spot for me locally. The prompt decode caching keeps things coherent and fast even when contexts get north of 100k tokens.

The 8 bit MLX unsloth quant of qwen3-coder-next seems to be a local best on an MBB M5 Max with 128GB memory. With oMLX doing prompt caching I can run two in parallel doing different tasks pretty reasonably. I found that lower quants tend t

No really, no. the last thing Github needs is yet another vibe coded fork of a mostly vibe coded app in the first place. If I ever get around to vibe rewriting-it-in-go I might share that.

MBP M5 Max. 128GB ram. oMLX. unsloth-Qwen3-Coder-Next-mlx-8bit. opencode with the telemetry stripped out. This seems to be the sweet spot for now for my local dev. Helps me to not accidentally blow through $100 in Claude tokens in a day

In my case, "background writes" literally means "do the io.WriteAt for this fixed-size buffer in another goroutine so that the one servicing the blob write can get on with encryption / CRC calculation / stuffing the

My usecase was building an append-only blob store with mandatory encryption, but using a semaphore + direct goroutine calls to limit background write concurrency instead of a channel + dedicated writer goroutines was a net win across a wide

If the performance charts are to be believed, this has uniformly worse performance in fetching and iterating over items than a boring old b-tree, which makes it a total nonstarter for most workloads I care about. It is also sort of ironic t

That is the most cursed description I have seen on how defer works. Ever.

It took quite a bit of scrolling until I found my old faves of dexed and zynaddsubfx, and I didn't see Helm ( https://tytel.org/helm/ ) at all.

None of the big browsers can be trusted at this point. Firefox is at best the least worst out of the big cross platform browsers.

DOS, early Windows, and early MacOS worked more or less exactly that way. Somehow, we all survived.

No, you cannot. Our abstract language abilities (especially the written word part) are a very thin layer on top of hundreds of millions of years of evolution in an information dense environment.

It isn't even really that -- most CLI tools are single-threaded and have a short lifespan, so your memory allocation strategy can be as simple as allocating what you need as you go along and then letting program termination clean it up

That sort of thing is why I wrote my own DHCPv4 server that is directly integrated with the core product at $DAYJOB. 10 years ago. Having the DHCP server determine how to handle PXE requests straight from the machine database made my life

Just need to make sure all your computation is done in a volume with infinite surface area and zero volume. Encoding problem solved. Now then, how hyperbolic can we make the geometry of spacetime before things get too weird?

Give monthly donations to your local NPR affiliate. Most of them have decently middle-of-the-road biased news, and a few have really good music programming (looking at you, KUTX).

CoW adaptive radix trees are the entire basis of $WORK's in-memory database -- we use them to store everything, then use boring old btrees to handle sorting data in arbitrary ways. A nice, performant persistent CoW radix tree would be

$WORK project heavily utilizes the test op to enable atomic updates to objects across multiple competing clients. It winds up working really well for that purpose.

I reach for adaptive radix trees over b-trees when I have keys and don't need to have arbitrary sort orderings these days. They are just that much more CPU and memory efficient.

Can't share my references with you directly, the implementation I wrote is closed-source and is heavily intermingled with other internal bits. But I can provide examples: 1. syscall.Iovec is a struct that the writev() systemcall uses

by vlowther 2y ago
Having written one of these, a few optimizations will go a long way: 1. syscall.Iovec allows you to build up multiple batches semi independently and then write them all in a single syscall and sync the file with the next one. It is a good b
