Crappy managers don’t know (or actively avoid) how to measure business value from individuals. So they need you to be in the office so they can physically see if you are putting in the effort.

Tokens is just yet another proxy for business value.

The problem they face is if everybody is judge by business value in dollars, crappy managers are the first to go

I love coding with bun. It comes with everything.

For my projects I don’t even need any additional dependencies. I use vanilla dom and sqlite

Why write:

When you can write:

Point.eql(a, c)

A sovereign wealth fund makes sense if fund with profits from exploiting our natural resources.

That is how Norway did it

Protip. Claude can generate state machine diagrams via mermaidjs blocks in markdown.

New comment by pyrolistical in "Coding Models Are Doing Too Much"

pyrolistical — Wed, 22 Apr 2026 18:40:36 +0000

I attempt to solve most agent problems by treating them as a dumb human.

In this case I would ask for smaller changes and justify every change. Have it look back upon these changes and have it ask itself are they truly justified or can it be simplified.

Seem like a solvable problem. Per origin cache control. But actually just load the data locally

Show HN: A simpler coding agent harness

pyrolistical — Thu, 16 Apr 2026 00:54:38 +0000

The system prompts that coding agent harnesses pass to language models are massive. They describe every available tool in detail — even the ones you never use.

So I wondered, what if I built something more minimal?

I tend to work on small projects where all the code fits in the context window. So I built a harness with a single tool: the ability for an LLM to edit my files.

The core algorithm:

1. Read every file in the project directory

2. Concatenate them with the user's prompt into a single message

3. Send it to any language model, instructed to respond with a message and a list of edits — each edit being a search and replace on a specific file

4. Apply the edits

I tried getting the LLM to generate unified diffs, but it kept producing malformed ones. Search and replace turned out to be far more reliable — the model copies text verbatim from the files already in its context.

This can be extended with a few more features:

1. A CLI that lets you continue the conversation or reset it. Dumber LLMs need this so it can see the mistake they made.

2. Automatic retries — if an edit fails, re-send the current files and have the LLM fix its own search blocks.

3. File deletion. I made it so that an empty search-and-replace on an empty file deletes it.

The LLMs I tested were local ones running through the LM Studio API. Gemma 4 was pretty bad. Qwen 3.5 was significantly better.

Where is the source code? You should be able to get any coding agent to generate you one using this post.

There was never the business value. But now remember this axios case and use it as ammo for the next issue. Just don’t abuse it

Agreed. I wonder if this silicon is designed for this benchmark and if not how useful is it with real code.

I would be surprised if this silicon area could not be better utilized for something else
