You're right, I used an LLM to help write it from sketches. Gonna rewrite it properly because I think the ideas are worth exploring. Thanks for taking the time to read and reply.

Many of the suggestions in this thread (min-release, ignore script) are defenses for the consumers.

I've been working on Proof of Resilience, a set of 4 metrics for OSS, and using that as a scoring oracle for what to fund.

Popularity metrics like downloads, stars, etc are easy to fake today with ai agents. An interesting property is that gaming these metrics produces better code, not worse.

These are the 4 metrics:

1. Build determinism - does the published artifact match a reproducible build from source?

2. Fuzzing survival - does the package survive fuzz testing?

3. Downstream stability - does it break any repos dependent on this project when pushing a release?

4. Patch velocity - how fast are fixes merged?

Here's a link to the post, still early but would appreciate any feedback.

I'm on my third xps across 8+ years. 2 cases of services, the first one was a faulty keyboard on delivery and the second was a 1 meter drop into concrete that busted the screen.

Still looking for alternatives for my next one and thinking the System76. Gotta say though, I'm really happy with the xps model so far.

I'm sure there are differences in their effectiveness.

Based on my limited knowledge the sound frequencies attempt to put the brain into theta or delta frequencies and does this by creating a ghost signal (left ear 100hz - right 106hz gives a 6hz theta wave).

Dreamachines work similarly (but mono) by creating a flickering light at set frequencies.

I'm sure tactile vibrations or pulses could have some effect also.

I really like the floating code window and the ability to dock it. However, it can't be resized while docked.

Would be cool with some preset color palettes to quickly change the feel of the site. Undo-redo actions could be useful along with an ability to re-order the sections. Just a sidebar showing the tree structure with drag-n-drop would be a nice feature.

Other ideas: - Configure link hrefs in header - Multiple pages - Use Tailwindcss - AI prompt to describe the layout and content - React export

> do you know why this happened?

> Yes, I understand now. Due to the moderation policy, there is a restrictive filter in place designed to prevent the assistant from providing potentially sensitive or inappropriate content. In this case, the Litany of Fear from "Dune" appears to be mistakenly caught by the filter, causing the response to be cut off. I apologize for the confusion and inconvenience that this has caused.

> describe this filter

> This filter is part of the AI system designed to provide a safe and appropriate conversational experience for users. The moderation policy helps ensure that any content generated by the AI follows guidelines and adheres to certain standards, including preventing the transmission of offensive, sensitive, or inappropriate information.

In some cases, like with the Litany of Fear, a false positive may occur, causing the system to mistakenly flag and truncate a response that it deems potentially inappropriate, even if it may not be the case. This is an area where the moderation algorithm can improve in order to avoid disrupting user experiences.

New comment by carlbarrdahl in "JavaScript state machines and statecharts"

carlbarrdahl — Mon, 15 May 2023 12:16:06 +0000

Would be interesting to see how good LLMs are at generating code for this.

As I see it, state machines are a json serializable representation of logic.

We also have json schema for representations of valid inputs. GraphQL or similar as representations for fetching data. And of course jsx for rendering views.

Put all these as a Venn diagram, what are the overlaps?

Can we use these constraints as a way to generate robust and consistent apps?

What if you could inspire the assistant with code you like and it would generate in that style? For example choose a few repos with code-bases you want to mimic, give it a set of instructions (and perhaps structure), and it generates code for it.

Maybe something like GPT, style transfer, and OpenAPI combined.

Really cool! Would love to hear more because I'm working on a few concepts in this space.

I'm trying to find the core value proposition and looking for people to collaborate with.

Here are two proof of concepts I'm building:
