You think I need an LLM to slopcode? :p

Codex chat: "Investigate skipped PLC ops"

Codex: To prove it, I’d compare both servers’ logs/cursors around 2026-06-13 20:03 UTC / 22:03 CEST, plus any restart/shutdown around then. If the missing server restarted while processing an export page whose range contained 2026-06-08T16:16:32.933Z, that’s the smoking oyster.

Me: Ohhh lol that's June not July, I'm a stupid

Codex: Heh, the finest debugger’s trap: the bug was in the calendar parser between chair and keyboard 😄
But yeah, that changes the interpretation a lot:

Excuse me what the fuck

comment from Daniel Gomes on micro.blog:

@manton Good decision. The vast majority of people are still on X. Hardly any know Bluesky (which has become a den of pedophiles sadly) and even fewer have heard of Mastodon.
For real reach you have to build up a following on X.

Reprocessing a feed with regexps in Ruby vs. calling a Rust module 🦀 (I've been working with 🤖 since yesterday on a new feed maintenance CLI for myself which shows progress/speed and lets me view & apply/cancel changes in one go, since it got kinda annoying when working on a lot of regexp tweaks…)

Are they beating the shit out of each other there or what?

Ah, I was never sure what that meant, thanks Ruby docs

Also some good tips here on what to work on to make your language/library more popular in 2026 (cc @cjrriley.ca)

An AI-enabled Haskell ecosystem would ask different questions. How do we make Haskell easier for agents to use well? How do we get more high-quality Haskell examples into model training data? How can we scale reviews? How do we make library docs full of copy-pastable, realistic examples, not just beautiful types? How do we make project bootstrap fast? How do we make error messages more agent-friendly? How do we reduce cold build times? How do we make common industrial patterns obvious to a model that is trying to help?

Haskell should be unusually well positioned to be relevant to AI-enabled engineers and agents. Type safety can be a huge advantage for LLM-generated code if the compiler is helping the agent converge quickly. But that is not the same thing as optimizing the language for humans writing code by hand. Agents have different bottlenecks. They are cheap at generating code and expensive when blocked. They benefit from fast feedback, clear examples, low setup friction, and errors that help them repair the code quickly.

I want Haskell to grow. I want it to matter. I want the things Haskell is good at - correctness, maintainability, compositional design, principled abstractions - to be part of the next era of software.

But these things have to be a priority. From what I can see, including Scarf's own view into open source ecosystem trends, Haskell's growth looks modest at best compared with what is happening elsewhere. I cannot share all of the underlying numbers at this time, but directionally the story is not hard to see: a lot of developer ecosystems are accelerating in the AI era, and Haskell does not feel like one of them.

The opportunity cost of this stagnation has never been higher.

The answer is to make Haskell the best version of itself for the world we are actually entering. That means taking AI seriously as a first-class user of the ecosystem. It means caring about build times, onboarding, documentation, examples, tooling, agent workflows and marketing, more than we care about type system research. It means re-allocating community efforts and even abandoning current areas of work. It means finding ways for the Haskell Foundation to collect enough money to fund and coordinate more technical work.

LLMs are now very good at writing code. They are not perfect, obviously, but they are good enough that the economics of software development have changed.

Historically, I thought about errors as something you caught in one of two places: at compile time or at runtime. Now there is a third place: code generation time. The model can often avoid the mistake before the compiler ever sees the code. And as the models get better, the relative value of catching every possible issue at compile time changes.

This is not to say type safety has become worthless. But the cost of typechecking matters much more now. If an LLM can produce a working implementation in a few minutes, but your compile step takes dramatically longer, then your language and build system have become a bottleneck in the development loop.

There are… secret ways (not sure if 100% up to date)

$Method 5. Self-hosted PDS If your account is hosted on a PDS you own or control, you can add these rules to your Nginx or Caddy configuration. for Nginx users: server { server_name pds.example.com; location /xrpc/app.bsky.ageassurance.getState { default_type application/json; add_header access-control-allow-headers "authorization,dpop,atproto-accept-labelers,atproto-proxy" always; add_header access-control-allow-origin "*" always; return 200 '{"state":{"lastInitiatedAt":"2025-07-14T14:22:43.912Z","status":"assured","access":"full"},"metadata":{"accountCreatedAt":"2022-11-17T00:35:16.391Z"}}'; } } for Caddy users: pds.example.com { handle /xrpc/app.bsky.ageassurance.getState { header content-type "application/json" header access-control-allow-headers "authorization,dpop,atproto-accept-labelers,atproto-proxy" header access-control-allow-origin "*" respond `{"state":{"lastInitiatedAt":"2025-07-14T14:22:43.912Z","status":"assured","access":"full"},"metadata":{"accountCreatedAt":"2022-11-17T00:35:16.391Z"}}` 200 } }$

Wait… you can set vertical-align to e.g. "2px" to move a thing 2px up? Why didn't anyone tell me?… I always did it with position:relative and e.g. top:-2px 😅 developer.mozilla.org/en-US/docs/W...

Man, these are some insane numbers… in Europe (via www.levels.fyi/heatmap/euro...) you're gonna get something like $5-10k/mo, so like $60-120k/year. Completely different planet.
