Happy to announce that @RepoPrompt Community Edition is now live on @github

Repo Prompt started as a tool for copy pasting, but soon stumbled into a world of context engineering.

Today, it has evolved into an extremely capable multi agent orchestration tool, by inverting traditional harness design to make an mcp server the primary agent, so that underlying cli harnesses can be swapped out.

This version of the app has been designed specially to thrive in the age of opensource driven by coding agents. This means that many of the legacy features you might think of Repo Prompt for have been removed to maximize the potential of its tools for parallel agents.

While this is a Mac native app, the project structure was redesigned to shed the need for xcode, taking heavy inspiration from @steipete’s work.

The repo borrows from @badlogicgames’s example of keeping a list of approved contributors, but adds a twist where all previous customers who opted in are automatically whitelisted.

I really think this repo can serve as a learning baseline for many to build novel agent experiences, without having to maintain complete harnesses, and while its currently Mac only, work is underway to deliver a composable core that can power cross platform apps just as well.

If you want to get involved with development, please join the amazing repo prompt discord community!

@TimSweeneyEpic @octal 100% Unintended consequence blast radius increases with lack of understanding of how interconnected life on this planet is. Humans cannot and should not bend nature to their will, but instead help keep it in its natural balance.

I was a bit hesitant about showing stuff like this just a month ago 😅

When we started showcasing real-time AI + SDF sculpting, I was afraid professionals would laugh if I showed no effort on the input models. The shape strength slider was also hidden in our first iteration, so I had no choice but to at least try and knock some more interesting shapes together.

Now that we're starting to focus on more powerful features and shape strength is finally unlocked, I'm starting to appreciate just playing with simple shapes.

Different stages of production have different needs. Sometimes you want full authoring over your creations, while other times you just want to quickly explore new ideas.

Relit-LiVE - Wan2.1 for pose-free vid/img relighting.

- Works without any camera tracking data
- Reflections/shadows are physically accurate
- Keeps lighting perfectly stable across long clips
- Relights, swaps materials, inserts 3D objects in a single workflow
- Preserves fine details and material roughness

The Dirty Little Secret of AI:

I wanted to see if I could train a full neural network on a real 1979 PDP-11. Spoiler alert - I did.

Allow me to explain transformers and attention when they're reduced to their most basic forms, all in 6K of program code...

One battle was won just as another is raging.

Meta lobbyists are pressing politicians around the world to pass tremendously privacy-invading and likely unconstitutional identity verification laws, forcing all citizens to upload personal identifying documents or biometrics to a huge variety of corporations in order to access services whose purpose is fundamentally about speech.

Advocates for this are saying everyone’s private info won’t be stored and therefore can’t leak, but there are many cases where this isn’t so. Amateur developers who make mistakes are one reason - and if 10,000’s of services have to verify identities then some won’t be up to expected standards. Customer support channels are another case; if an automated process fails and customers email support agents then those documents are stored on additional servers, such as the Discord contractor’s servers that were hacked. Then there are dodgy corporations whose lawyers come up with clever theories allowing them to repurpose and broker data. And finally, there are lawsuits and regulatory investigations that require retaining documents for long periods of time.

There are much better solutions that are not driven by vast power grabs by government and corporations: give parents the ability to manage their kids’ device accounts and make decisions about what features they can access. Apple, Google, Microsoft, Sony, Nintendo, Disney, Valve, Epic, and many others have done exactly this.

The best advocacy in this area is actually Apple’s. But it’s being ignored.

It’s a tragedy of their own making that Apple has lost so much public trust by crying wolf with pretextual safety and security claims calculated to protect their App Store monopoly.

Now that there is a looming privacy crisis and Apple has a truly good-faith solution based on parental controls, politicians are ignoring it to pursue the Meta lobbyists’ approach. Though the US has consistently overturned invasions into First Amendment rights, the campaign will probably succeed in most other countries, resulting in the digital world being a more corporatized, governmentized, and surveilled place.

Even worse - each neuron that contributes to your cognition and consciousness might contain 100,000 Microtubules - each Microtubule Operating at 10,000,000 oscillations per second - and being Quantum photonic memristers

Good luck with the AGI tho

@jon_barron This is a good example of using generative ai to drive efficient interaction /rendering with game tech, in contrast to the idea of generating pixels from a scene graph / world sim. There may also be a space for gen ai to generate run time behaviors and mini simulations in-game

We're so close to vibe fortnite

@TimSweeneyEpic I can see this working as you say, using AI as the last mile expression from a deterministic scene graph and simulation. But I can also see it working in the inverse, where a sparse voxel grid of latent context informs the expression of efficiently computed game-engine elements

@NOTimothyLottes The idea of `number of lines of code` associated with anything meaningful is beyond my comprehension.

@kimmonismus I bet it fails on the grass. I don't think these policies are robust enough just because they can operate on a flat hard surface

Next year we'll be building bridges from EmberGen, LiquiGen, and IlluGen to the top 3 game engines. IlluGen will be getting graph conversion support to shaders in all 3 engines which is a major upgrade and yup, we'll be supporting Godot!

Cat's out of the bag:
FEX, an emulator I've been working on these past 4 years, is going to be part of the Steam Frame to bring x86 Windows games to an ARM Linux VR headset! 😊
