I am building a tool to manage your image generation inference. It uses ComfyUI as the backend and it allows you to index, search and invoke your workflows.

It makes it super easy to using existing workflows to chain them together into more complex outputs.

All of this withouts nodes.

Early release is out here: https://github.com/svenhimmelvarg/kaleidoscope

I have decided to put my GAS behind me and focus on truly learning one musical instrument, the MPC Live III. I aim to learn all the features and come up with several workflows at which I become fluent. The goal is to enable me to create songs without having to worry about constantly figuring out how to do something.

I got no links to share but I’m working on a chess trainer app. Unlike the myriad of other platforms out there my trainer offers a holistic approach showing you where exactly you make mistakes (in the opening or middlegame) and how they carry on into your gameplay. It’s an offline application, no subscription, one time purchase. Works by downloading your data from your favourite chess platform.

Just started this weekend on https://gitlab.com/get-otter/otter-sdk

Its dbt inspired stream ETL tool (or maybe just the TL?), it currently just has a dev mode that does RabbitMQ to local Parque files while I'm getting the core of it to a place I'm happy with.

It runs SQL models against the incoming messages and outputs the results to one or more output tables. Has a local WAL so you can tune it to have sensible sized output files (or not, if you need regular updates but at the expense of query perf.)

Planning on adding Protobuf messages, Kafka as a source and S3 and Iceberg tables as sinks this week.

Lightly inspired by a some projects at work where a lot of time and effort was spent doing this and resulted in something not very reusable without a lot of refactor work. Feel like the stream -> data lake pattern should be something that is just SQL + Config, same way dbt is for transformations within a data warehouse.

No plans on adding any cross message joins or aggregations as that would require cross worker communications and I explicitly want to keep the workers stateless (minus the WAL of course)

Would really appreciate any feedback on the core concept, esp. if this is something you'd actually use in prod (if it were finished!) Not sure if there is something that does this already that I don't know about, or if this genuinely fills some sort of hole in the exisitng tooling

A backend for an open source bbq thermometer firmware that a mate and I wrote last year for a product that was discontinued (https://github.com/epiecs/free-grilly).

The github repo for the backend is still private atm but we are planning to release soon once we have a gui ready for that new backend. The plan after that is to learn pcb design and electronics and maybe design our own bbq thermometer :)

Handcrafting a new version of Collider.JAM (http://collider.land/) - a JavaScript framework for rapid game prototyping. Ludum Dare 59 is coming, and any coding samurai needs to sharpen their katana. And Ludum Dare is a perfect excuse to do just that.

IMHO, Ludum Dare is The Jam for many reasons and it is a pity that it's slowly fading away (the last Mike Kasprzak's post explains some of the challenges https://ldjam.com/events/ludum-dare/59/$424396/ludum-dare-59...). It looks like we don't have many events left in the pipeline, and this one will be a nice opportunity to participate and still enjoy the sunset of the era and the vibes of the awesome community.
