https://play.google.com/store/apps/details?id=com.blazingban... Completely free, no ads, no in-app purchases and no accounts / network required offline voice transcription. I have also built the macOS/Windows/Linux versions which I'll also make free to download and available on my site soon ( https://blazingbanana.com/ ). iOS version is built and works (extremely well), just waiting for the Apple Developer signup pro…

I really liked wisprflow on my mac but my daily driver is Manjaro KDE. I have stitched together a bash script that copies the transcription (right now I am using the Parakeet TDT 0.6B) to my clipboard. I would give this a try on linux when it becomes available.

Slowly degoogling my life. Switched to FastMail a while ago, it works. Have written a simple shopping and todo list web app, and a minimal photo gallery. All very simple, mostly for one user only: Myself. Using these as excuses to learn about coding with LLMs. As I have retired a few years ago, I can afford the time, and work with no stress or deadlines. Also slowly improving my beer tracker system. All this as perl-based cgis under Apache, running on my home server/workstation.

I'm working on a graph representation of complex data flows through a large organisation. The graph looks like crap, partially because hierarchical dagee graph layout algorithms apply a naive way of removing cycles that ruins the shape of the graph.

I've figured out a better way to remove cycles that preserves the shape of the graph in a way that works well for our purpose. Now I just need to figure out how to minimise edge crossings and line up nodes in such a way that it's more immediately obvious how the data flows between different systems.

It started out as a take-home assignment for a job I’m interviewing for (they asked for about 10% of what I ended up implementing but I wanted to do/show more :). It’s an aggregator for crypto exchange data.

The app reads the public data stream from exchanges, handles the nitty, gritty details of each exchange’s websocket connections, deals with its quirks, cleans up and normalizes the data into a uniform structure (currently only supporting spot trades) then exposes it downstream as an SSE stream.

Uses Go, Templ, and Mithril.js, and is open source

Working on a TUI tool which demonstrates the behaviour of X86 SIMD instructions. This is all done in Go assembly, and is probably most valuable for Go programmers. The problem for me was trying to read and understand the implementation of a swiss map implementation. The SIMD instructions were challenging to understand and the documentation felt difficult to read. I thought that if I had an interactive tool where I co…

If anyone wants to try it out (the UI is a bit rough). I will try fix up any issues that are uncovered.

Working on a visual language learning app called Snapalabra!

The idea is simple: You look at an image and describe what you see in your target language. That's basically it!

My reason for building it was that even though I can understand a lot of spoken spanish, I really struggle to construct sentences on the fly when speaking. Doing a few minutes of active learning like this each day really helps remap my brain a little, and I quickly run into situations where I hit a wall and realize I actually don't understand something as well as i had thought.

The app also gives a little feedback on what i have written from an llm, and it also provides clues that I have mapped to each image.

At the moment I am using it mainly for intermediate Spanish and beginner Irish, and personally I find it really helpful for both. Basically learning vocan for Irish, and more serious sentence structure etc. in Spanish.

I know a lot of people absolutely hate the idea of mixing LLMs with language learning, and I can kind of see why, but I personally find it really helpful in certain cases. If you are already doing classes, and consuming content in your target language I think something like this will be really helpful for a 5 minute coffee-break type activity in the morning. Its not a language course and I have not intention for it to be one. Its just a supplementary little tool that helps with getting your brain thinking in a new language and it is free to use.

- Building a micro-learning platform that uses AI-powered role plays and conversational assessments to gauge learner understanding instead of eg. a multiple choice questionnaire.

- I’ve just started designs and initial setup for a personal productivity system heavily inspired by the Newton & HyperCard and built in Rust. Idea is to use LLMs to build GraphRAG-like connections between content & break out of the standard app+document model. My current thinking is having ‘frames’ of content (notes, sketches, events etc) that are acted on by capabilities and displayed in views (timeline, calendar, stack, knowledge graph etc).

- Also working on a static site generator and CMS webapp that creates sites that can be viewed on anything, from web browser to TUI. Like if Gemini or Gopher also rendered to html.
