@Liu_eroteme Sure thing, all the code is available here (sorry that it’s very messy, I’ll clean it up at some point so it’s easier for others to re-use): github.com/pfletcherhill/…

haven't checked out the paper yet, but do you share model, training, and eval code? I've been meaning to eval a specialized basic transformer vs one with my wip diffusion augmented latent model predictive control* addon on arc tasks, but haven't really had the time or motivation to start, specially since I've done fuckall research on arc tasks and how good training data for that looks like *(kind of like a gan, but generative and adversarial models share a block of middle layers, and work on different input and output modalities)

Over the past few months, I've had a lot of fun working on the @arcprize. Here's my write-up on Mini-ARC. It's a very small transformer model trained just for ARC puzzles.

My goal for working on the @arcprize was primarily to learn a lot, which I did! The competition was an amazing scope for self-education. Thanks again to all the organizers.

Here's a link to the full paper: paulfletcherhill.com/mini-arc.pdf

@jordanfrankfurt @tarunchitra Gotta respect polymarket for the patience and conviction

@tarunchitra @pfletcherhill @pfletcherhill 🫡 Huge fan and I still randomly look at the old veilco github from time to time.

pouring one out for veil.co

@JonathanHillis Here’s my list paulfletcherhill.com/solarpunk

What book would you nominate as the solarpunk manifesto? I think I might choose Buckminster Fuller’s Operating Manual for Spaceship Earth Written in 1969 (!) it provides a visionary framework for building towards global abundance for humans and the environment

@sevensixfive Yeah definitely! Will dm you

@pfletcherhill Wanna join a Signal chat about it?

Is anyone else re-reading Kim Stanley Robinson’s Mars books?

@patrickc Go to Freiburg and visit the eco-district of Vauban

Southern Germany feels unfairly overlooked relative to its more celebrated neighbors. Architecture of Bamberg a particular highlight.

@holz_bau 🙏 thanks for putting it on the map for me

On Solarpunk #9 A brief travel report from Freiburg, Germany. Read about the city's utopian Vauban district and how it may inspire new eco-friendly, walkable, family-oriented neighborhoods. onsolarpunk.substack.com/p/on-solarpunk…

🌳🏭 On Solarpunk #8 We go back and look at Arthur Morgan's ideas of small town industry, Yellow Springs, Mondragon, and how those influence a Solarpunk future. Thanks to the @Center4NewEcon, where the majority of the research for this post happened. onsolarpunk.substack.com/p/on-solarpunk…

Recently, I've been diving deep into the Solarpunk aesthetic. It's one of the most (and only) optimistic sci-fi genres, and I think it will help stoke a more positive public imagination. Each week I'm writing (in public) about what I learn. Follow here: onsolarpunk.substack.com

Today we’re launching Heat Pumps Hooray: heatpumpshooray.com We looked everywhere, and we couldn’t find a tool to understand exactly what savings ($$$ and emissions) you could get in your own home. So, we built one. Here’s why we did it…

@russgeorge2 Terrifying. Where is this diagram from?

Only the plankton can save the ocean, they repurpose our deadly CO2 into Life, preventing it from becoming acid death.

@holz_bau @sevensixfive Thanks for the shout-out! Not straightforward, but I think there are ways to improve recycling of refrigerant at end-of-life AND make better use of low GWP refrigerants (like using CO2 for high temperature/water heating settings, allowing flammable refrigerants when safe)

@serbantanasa @CJHandmer I imagine you'd still use AC for cooling, unless magnetocaloric or barocaloric systems have become widely available. Fwiw I'm a huge fan of heat pumps. But if efficiency really doesn't matter at all, resistance heating is simpler/cheaper.

@pfletcherhill @CJHandmer I’m not a physicist: can you be a bit more explicit? I get using electric resistors for heat, but what is the equivalent thing for cooling?

At the TED talk yesterday, Elon estimated we'd need 300 TWh of batteries to complete global transition to post-carbon energy, which is about 1000x current annual production. At @TerraformIndies we found similar numbers for solar PV. The next 20 years will be wild.
