yeah we're producing more but it's taking less of our time to produce, so we can realloc that time to reviewing, partially?

Agents & what we're choosing As coding moves more and more towards AI-based workflows, we're seeing a lot of tooling being built specifically for agentic coding. New types of tools, like agent harnesses and ACPs, are built around...

just don't do 1000+ lines PRs and you can still manually review it and confidently take liability for your code?

find a gap in the market and vibe code a solution

it's a huge slopportunity

My "absolutely no PRs from anyone exposed to microplastics" policy is raising a lot of questions answered, quite frankly, by the policy itself

This is actually really interesting! Why do we allow Claude to be on the commit byline, but not Zed, or Rust Analyzer, etc?

The fact that computers now do the correct thing when you say β€œplease rebase” is nothing short of a technological miracle.

just found this tidbit in a CLAUDE.md file: "If the code is not fully optimized before handing off to the user, you will be fined $100."

Remember, AI is non-deterministic, no matter how much you add to your AGENTS.md.

If you want determinism, do the same we've done for decades: script it.

For example, don't ask AI to "test my app end to end" but instead set up a CI e2e test check.

Code isn’t a business. Long-standing tradition of engineers getting that wrong.

as an aside: I asked the other day whether the difference between Rust and Go matters to an agent.

it does. The stuff you can easily leverage with Rust smokes out entire categories of LLM misbehavior that the language doesn't control for.

mutants is maybe the best tool I've ever used for testing

Rustaceans.AI A community for Rustaceans who are building with AI

AI coding tools promise huge productivity boosts, but Rust devs we spoke to are struggling to capture those. Nobody's sharing what works, so there's no best practices.

We're building a community to change that. rustaceans.ai is a community for Rust + AI workflows, tooling, and real projects.

Anthropic must be building the model specifically with this in mind, there's no other way it's this good.

Bullshit Bench V2

new: 100 questions across several domains

- Anthropic & Qwen still on top
- Reasoning seems to hurt
- New models are *not* better than old (except Claude)
- Seems to be independent of domain

I use the bash mode in Claude Code quite a lot and I feel strong shame for the compute time I've wasted on forgetting the exclamation mark

eurosky.social is only behind blacksky.app in top decentralizers on arewedecentralizedyet.online

looks like the decentralization is happening! might move over soon.

this is a good thing but I feel like they should have policy for additional package repositories beyond npm
