A "greatest common denominator" format for data synchronization.
Like, JSON done right.

#702Myself, mind and body
Everyday, I get up and cold plunge. I exercise twice a day. I eat carnivore diet. I do red light therapy. I drink a gallon of water. I read 10 pages out of two books. Sometimes I get a third exercise in. I use the sauna (20 minutes at 205F). I stand on a vibration plate for 10 minutes.
I also play factorio.

#703A sqlite extension that provides a virtual table backed by an Automerge document ( https://automerge.org/ ). I believe that there are plenty of applications that could benefit from the collaboration or sync-ability that CRDTs* provide, but that don't need to manage the CRDTs directly. Moving the CRDT management into the database seems like a natural fit. It's very early, and not public anywhere, but I'd be happy to c…
Looks like we overlap somewhat https://github.com/gritzko/librdx
I had some success embedding CRDT into LSM databases. Those are built around merge operators.

#704A new YouTube app/player, for my kids. It allows us to control the algorithm. It’s all LLM translating to YouTube search queries under the hood. Visually it looks the same. The suggested videos come from predefined buckets on topics they love. E.g. 33% fun math, 33% DIY engineering, 33% creative activities. Video recommendations that have a banned word in the title/desc don't get displayed e.g. MrBeast, anything with…
For anyone wanting interesting YT videos for their kids (and not wanting to take anything away from OP's project), I highly highly recommend thekidshouldseethis.com. It's basically a curated stream of cool videos, and I would feel totally safe letting my daughter browse it alone (she never does because we usually watch them together, but the curation is that good). Videos on all sorts of topics, and good enough to be…
I was just watching with my young kids YT videos about casting metals into objects and how steel is made, sometimes modernity is great

#705I built 3 electric cars from 2018 to 2023 and drove them 20k miles. My own firmware and controllers, with an https://openinverter.org motor controller Now I release my knowledge in bite-sized chunks on my new YouTube channel to help others: What's a battery management system? https://www.youtube.com/watch?v=_QsMoCrSTYc What is the C-Rate? https://www.youtube.com/watch?v=dDu1fRtKfsA What is battery balancing? https://…
Self-built EV? No one can tell me otherwise: you're the chosen one. Lisan-al-Ghaib :)
Why would you self-build when you could just lease an Al-Ghaib?

#706I've always struggled to find a place where serious programmers would be there to talk and exchange experiences on various topics related to software development. So I built a simple site from scratch where we can chat, send files, post things and share images and links on a single platform. https://chat-to.dev

#707I'm building a language learning app: https://yakk.app . Way to go, but made a good start and even a little bit of money so far. I quit my job and moved to Asia on savings to keep building. LMK if any of you guys are in Bangkok, let's hang out.
I've lived in bangkok for 10 years, feel free to drop me an email hyper@hyperworks.nu
I'm currently hacking on some AI projects for language learning also hahahah

#708A custom email sorter / spam filter that uses a fineruned multimodal LLM: my emails are turned into images (turning them / extracting html then rendered with selenium) and passes to the vision LLM. I went from ~200 to ~15 useful emails a day. Raw code is here: https://gitHub.com/beniz/llmbox All runs locally, the finetune is a plaigemma-3b (from mix-448). Acc/F1/prec/recall are all within 99.99%, including on llm-gen…
i wonder what a spam mail looks like that was created by an LLM with the goal of evading correct classification by your LLM ...

#709A colouring app that is free and simple. I want it to avoid advertising or anything that makes apps nowadays irritating.
Try it out, it's free!
If you don't have an iPhone, you might have success with the desktop version at: https://color.vos.lol/app

#710Decarbonising buildings and massive warehouses.. It's a very fun mix of hardware (for data collection), and crazy SQL queries to model energy flows between buildings, solar, batteries, etc. Considering just one building is pretty easy: consumption = imported - exported + generated - stored + dispatched. carbon = carbon intensity * imported cost = tariff * imported but then you add a site with a couple of buildings, s…
Also somewhat working in this space. Building a BMS (Building management system) to manage and control everything in commercial buildings. Think Homekit for commercial. There's something like 70% of buildings don't use one and they can be much more environmental friendly.
