I'm enjoying building a website with solitaire and puzzle games.

I am currently rewriting the engine for the Nth time and plan to add 400 games to the platform in the coming months, as well as social features such as daily challenges, awards and leaderboards.

My ambition is to make this project the largest collection of free modern solitaire games available for all kinds of devices.

A straightforward and simple AI agent framework. It puts a lot of emphasis on the loop and the steps in that loop. You can change in real time the model, the temperature, the tools, the history. You're also able to spin-off work on a branch and then add the result of that work on the main branch. Still early but developing very fast.

I always wanted a minimalistic CSS framework for my projects, so I started to create my own: THINK THINK is a modern CSS-first UI framework built on semantic HTML, custom elements, and data attributes. Uses :has(), container queries, and density scaling. No classes, no build step. It‘s work in progress but I‘m pretty happy with the outcome so far, especially the data table component and automated Insights. I know it‘…

This is very cool! Is it open-source? I'd love to see what it's like to use

https://instagit.com I’ve been shipping AI-written code for 2 years now. I can build something amazing in 40 mins but then spend 4+ hours debugging because the agent has no idea how the libraries it’s calling actually work. Docs are stale, StackOverflow is dead, training data is outdated. Every engineer I talk to has the same problem. So I built Instagit, an MCP server that lets your coding agent understand any GitHu…

hey irrelevant question, what tools you use to make such great landing pages for your products? your instagit.com looks great, what's your vibe coding workflow?

Delving deep into novel ways to extend Excel and make it more accessible. Perhaps different approach to copilot in that AI is only used during authoring, the yielded output being a standalone artifact.

The result is https://xllify.com

It embeds Luau which tames the very old school C SDK. This means that the same code can run as native add-ins on Windows (XLL) and the more modern-but-far-slower web engine, thanks to WASM. Luau is safe and fast.

The exact same bytecode runs in both styles of add-in. You get the performance of native with no extra work. Many approaches for writing custom functions are unacceptably slow, particularly when their inputs come from fast moving realtime data feeds.

I know Luau is perhaps a left-field choice. However, coupled with a coding assistant and bringing that lightweight conversational dev experience right into Excel (xllify Assistant is an add-in itself) this is perhaps less of a barrier.

I'm working on PC Part Picker for hi-fi stereo gear. https://buildhifi.com Some technical highlights: - Graph-based signal flow: Products become nodes, connections are edges inferred from port compatibility (digital, analog, phono, speaker-level domains) - Port profile system: Standardized port definitions (direction, domain, connector, channel mode) enable automatic connection inference - Rule engine: Pluggable rule…

This is fun! I put my (slightly oddly setup) system into it but I couldn't reconfigure which set of speakers were connected to which amp, or reorder the signal chain at all. Is this a planned feature? E.g. I have an integrated all-in-one amp that drives my main speakers but I tap off the pre-amp output into a secondary integrated amp that drives two secondary sets of speakers but your app assumed that my second amp was driving all six speakers and so spat out a warning about power levels...

Open-source RAG infrastructure.Every team I talk to has the same experience: RAG works in the demo, breaks in production.

We handle ingestion through retrieval with optimizations baked in. 97.9% on HotpotQA vs 88.8% for standard RAG. Model-agnostic, 22+ file types, built-in citations, MCP server. MIT licensed.

I built a Pokédex for zoo trips for my girlfriend: https://www.zookeeperapp.com https://www.mikeayles.com/#zookeeper-wip It lets you take photos of all the animals you see to collect them, when you 'capture' a new animal, it gives you fun facts about them. I seeded it with UK zoos, but there's no reason it can't work elsewhere. It was built because the signage at a zoo we went to was terrible and we had no idea what…

That's a lovely idea! I wanted to build something similar for safaris but the lack of network in remote areas makes it a bit tricky to use online image recognition models. I never went down the rabbit hole to use offline ones.

Fetching every church from IRS data; using a small local Mac mini LLM to match to their Google result, fetching site and (eventually) running a data enrichment LLM pass to determine various positions, metadata, and services offered. I just really wanted to see the data in aggregate. My current match rate is 30% with qwen2.5-14b. Doing my best to avoid spending a lot of $ on the processing even if the Mac mini is slow…

I love this idea. I love that you're using these new tools to do what would essentially be weeks/months of work by a small team of people. Elaborate on "toxic traits" and "Speak truth to power about how a lot of them turn a blind eye to this political moment." please. No judgement, I promise.
