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, for starters. * Slavery of captives from Africa? Pretty much everyone with colonies in and around the Caribbean was guilty of that too. * Multiple unnecessary wars that have killed millions of people? That encompasses more or less all of European history.

By all means, criticize Palantir. But don't pretend US history has anything in particular that would set up the prerequisites for it to exist.

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 to lose the plot after about 170k tokens in context.

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 when exploring different performance tradeoffs the backend of my $DAYJOB codebase.

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 resulting byte stream into fixed-size buffers". Handling it that way lets me keep the IO to the kernel as saturated as possible without the added schedule + mutex overhead sending stuff thru a channel incurs, while still keeping a hard upper bound on IO in flight (max semaphore weight) and write buffer allocations (sync.Pool). My fixed-size buffers are 32k, and it is a net win even there.

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 variety of write sizes and max concurrent inflight writes. It is interesting that frankenphp + caddy came up with almost the same conclusion despite vastly different work being done.

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 that one of the key performance callouts is a lack of pointer chasing, but the Go implementation is a slice that contains other slices without making sure they are using the same backing array, which is just pointer chasing under the hood. I have not examined the code closely, but it is also probably what let them get rid of the black array as a performance optimization.

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.

Only if you are doing in-place updates. If append-only datastores are your jam, writes via mmap are Just Fine:

Before it was an ACID compliant database, it was also the fastest backup solution on the market: https://bofh.bjash.com/bofh/bofh1.html

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 so much simpler.
