There Is Too Much 30 days ago

Definitely put your finger on what I’ve been feeling.

What AI did was give every engineer a small team of tireless, fast, occasionally-wrong direct reports. And with the team came the manager’s problem. The discomfort engineers are feeling right now isn’t an AI problem. It’s a delegation problem, and delegation is the oldest unsolved problem in our discipline.

Very good synthesis.

I’ve been using MixedBread, which is a pretty old model at this point. Recently, I tried comparing it to some newer models and was disappointed that the results weren’t dramatically and uniformly better.

You probably can’t go wrong if you pick a recent one that scores decently well on benchmarks and is at the right price point (or memory requirement) for whatever you’re trying to do.

This is great. It would be nice to be able to add a custom dictionary for words that are often misunderstood.

This sounds interesting.

Reading your website and the investor deck, one of my main questions was "who is behind this (and is this just AI-generated)?" It would be useful to put more of a bio on there.

Not having macOS/Windows support is going to make it hard to develop with. Would it be possible to build some kind of shim on top of other libraries that mirrors the API, even if it doesn't match the performance?

Also, one of the advantages of using a popular HTTP server stack is getting lots of battle-tested middleware that other people have developed and tested. Is there any way to leverage any of that or do you need to build everything from scratch? Granted, that is certainly somewhat easier in the AI era, but still.

You should try Scour (https://scour.ing)!

You specify your interests as free form text, it ranks articles by how closely they match, and you can consume your Scour feed as an RSS feed to read it in NNW.

Deno Sandbox 6 months ago

In Deno Sandbox, secrets never enter the environment. Code sees only a placeholder

The real key materializes only when the sandbox makes an outbound request to an approved host. If prompt-injected code tries to exfiltrate that placeholder to evil.com? Useless.

That seems clever.

Developer here, happy to answer any questions you might have about Scour!

Also, feedback on the product or the docs is very welcome!

I agree that Opus feels like a step change.

Claude code with sonnet was pretty good but needed a lot of back and forth to get to the right solution. Opus feels closer to a colleague, maybe not your absolute best colleague, but far from your worst.

Making RSS More Fun 8 months ago

Glad you think so!

There isn't a way to block feeds (yet), but you can subscribe to specific feeds, which basically acts like creating your own list of allowed feeds.

Separately, I'm going to be working on letting you exclude content from certain domains (which was requested in https://feedback.scour.ing/33).
