sccache is pretty easy to set up and you can back it with S3, memcache, redis, etc.

Do you have a link for this one? Would love to see it.

Can you (err... buildcache) cache Rust proc-macros? I've been battling this with sccache and I'm now maintaining a 10-patch deep stack for the next.js build CI.

Windows builds were ridiculously poor on cache hits rates too because of non-determinism that was not able to figure out.

I'd be happy to test it out.

I couldn't find any information on this, but is it possible that given how nicely exponentiation and logarithms differentiate and integrate, is it possible that this operator may be useful to simplify the process of finding symbolic solutions to integrals and derivatives?

mmastrac — Tue, 07 Apr 2026 21:48:56 +0000

The mostly likely quantum attack on Bitcoin will be a catastrophic transfer of large wallets to burn addresses along with a massive short position. No need to worry about washing stolen coins when you can just enjoy your "well timed" legal short position's windfall.

If you're installing Samsung Magician for firmware updates, keep in mind that you can always update your firmware without using it and it's just as safe.

I wonder if https://crates.io/crates/apple-codesign is sufficient to codesign these. Apple usually re-uses these sort of things.

New comment by mmastrac in "Lat.md: Agent Lattice: a knowledge graph for your codebase, written in Markdown"

mmastrac — Sun, 29 Mar 2026 13:50:06 +0000

I definitely agree with the need for this. There's just too much to put into the agents file to keep from killing your context window right off the bat. Knowledge compression is going to be key.

I saw this a couple of days ago and I've been working on figuring out what the right workflows will be with it.

It's a useful idea: the agents.md torrent of info gets replaced with a thinner shim that tells the agent how to get more data about the system, as well as how to update that.

I suspect there's ways to shrink that context even more.

New comment by mmastrac in "OpenCiv1 – open-source rewrite of Civ1"

mmastrac — Sat, 28 Mar 2026 22:55:31 +0000

This is a cool project, but the author should note that they _are_ likely creating a derivative version of Civ1 here. It might look somewhat different, but that's clearly just 16-bit (?) intel opcodes in a slightly spicier form.

It's very unlikely this sort of approach will end up with a copyright-free codebase, though it might be useful as a source for a cleanroom approach. The author shouldn't be discouraged -- lots of other recompilation efforts work this was as well, but it's a muddy place to be.

New comment by mmastrac in "I decompiled the White House's new app"

> It’s hard to imagine a smug article like this dissecting a product of some other administration

Did the other administration put a "fake news" and "report to ICE" and grifting link to their own social network in their apps? I feel like you are perhaps papering over a whole lot of general shittiness of this app that didn't exist in less amateur previous administrations that at least tried to follow the norms.

You omitted these items immediately above that line:

Injects JavaScript into every website you open through its in-app browser to hide cookie consent dialogs, GDPR banners, login walls, signup walls, upsell prompts, and paywalls.

Has a full GPS tracking pipeline compiled in that polls every 4.5 minutes in the foreground and 9.5 minutes in the background, syncing lat/lng/accuracy/timestamp to OneSignal's servers.

Loads JavaScript from a random person's GitHub Pages site (lonelycpp.github.io) for YouTube embeds. If that account is compromised, arbitrary code runs in the app's WebView.

Loads third-party JavaScript from Elfsight (elfsightcdn.com/platform.js) for social media widgets, with no sandboxing.

Sends email addresses to Mailchimp, images are served from Uploadcare, and a Truth Social embed is hardcoded with static CDN URLs. None of this is government infrastructure.

Has no certificate pinning. Standard Android trust management.

Ships with dev artifacts in production. A localhost URL, a developer IP (10.4.4.109), the Expo dev client, and an exported Compose PreviewActivity.

Profiles users extensively through OneSignal - tags, SMS numbers, cross-device aliases, outcome tracking, notification interaction logging, in-app message click tracking, and full user state observation.

mmastrac — Wed, 25 Mar 2026 13:44:41 +0000

Is this a tradeoff between GPU-computation-expense vs accuracy? ie: you could quantize into segments or grids on the unit circle/sphere/etc, but that's too expensive so it's better to just quantize to a Cartesian grid because the GPU can decompress cheaper?

I've been playing around with type mapping like this in a highly experimental crate. The ability to map, filter and reduce types is insanely powerful but it's tough to get ergonomic syntax.

New comment by mmastrac in "What is agentic engineering?"

mmastrac — Mon, 16 Mar 2026 02:22:20 +0000

After three months of seeing what agentic engineering produces first-hand, I think there's going to be a pretty big correction.

Not saying that AI doesn't have a place, and that models aren't getting better, but there is a seriously delusional state in this industry right now..
