If you’re brewing from ground you really don’t want boiling 212F water as you’ll burn the grounds. I do my pour over at 185F and get smooth ready to drink hot coffee with no/low acidity.

Store all data in one of those nocopy encodings, capnproto/msgpack? Then each language can read the same memory but with the language specific SDK

How are you not learning from reading all the code produced by Claude? Is auditing a new codebase or onboarding to a new project any different from creating a new codebase w/ Claude?

Reading code and understanding it is a very important skill and now might be the most important skill.

Yeah nix is great for this. Also I can update infrequently and still package anything I want bleeding edge without any big issues other then maybe some build from sourcing.

Packing software with nix is easier than any other system TBH and just seems to be just getting easier.

That layering algorithm is also configurable, though I couldn’t really understand how to configure it and just wrote my own post processing to optimize layering for my internal use case. I believe I can open source this w/o much work.

The layer layout is just a json file so it can be post processed w/o issue before passing to the nix docker builders

We’ve had issues with the centralized DERPs just blackholing traffic when we startup ephemeral nodes in CI. This is despite us ensuring that all important peers can establish direct connections to each other. But there is some bootstrapping that is happening before both peers negotiate.

Having said this, it’s been almost a year since the last incident of this. It’s been rock solid the last months. Ok sure using these new peer nodes will greatly reduce this from even a chance of happening anymore. :hacks away:

Maybe this is why I’m different. I love reviewing code, it’s a great way to learn about a system, get new ideas. Diffs are great, see how things are interconnected

Don’t do it, your project here on zig is a much larger net positive for civilization than you spending your time at those protests.

<3 zig and want io interface in everything!

This one should have been prevented because the Waymo should have been driving at max 10mph

The unpredictability was jarring to me as a passenger in a Waymo.

New comment by ghthor in "I built a 2x faster lexer, then discovered I/O was the real bottleneck"

ghthor — Sun, 25 Jan 2026 09:18:34 +0000

I actually ran into this issue building dependency graphs of a golang monorepo. We analyzed the cpu trace and found that the program was doing a lot of GC so we reduced allocations. This was just noise though as the runtime was just making use of time waiting for I/O as it had shelled out to go list to get a json dep graph from the CLI program. This turns out to be slow due to stat calls and reading from disk. We replaced our usage of go list with a custom package import graph parser using the std lib parser packages and instead of reading from disk we give the parser byte blobs from git, also using git ls-files to “stat” the files. Don’t remember the specifics but I believe we brought the time from 30-45s down to 500ms to build the dep graph.

Not sure the docker license supports calling distribution patches “unauthorized”

Pretty sure doing your own research turns you into a conspiracy theorist; so I don’t think we’re supposed to do that anymore.

I think it’s pretty obvious that is the OP automates this manual part of their workflow that it will improve their iteration speed. The thread root is just saying stop copy and pasting and use the built in tooling to communicate with the LLM apis

New comment by ghthor in "Comparing AWS Lambda ARM64 vs. x86_64 Performance Across Runtimes in Late 2025"

ghthor — Tue, 02 Dec 2025 21:54:10 +0000

Lambda in my eyes is super useful for isolating a security context, such that you can give elevated privileges to a less protected place via permission to execute the lambda; isolating something dangerous or secret from the less secure place

Any chance that it can take advantage of webgpu, or is it already doing that from this wasm build?
