An vscode extension to organize my lectures using a kanban style structure, saved as markdown files and allows specific md-formats to convert into presentations or other documents (currently marp (pdf, pptx, html) and i'm currently looking into pandoc). It's a vibe coded project i worked on in the evenings over the last 3 months.

#12DeepFabric - Generate High-Quality Synthetics, Fine-Tune, Measure, and Evaluate models in a Single Pipeline
Recently used the project to train a 4B model to outperform Claude Sonnet 4.5 and Gemini Pro 2.5 at Tool Calling. Colab here to run a free T4 GPU:
https://colab.research.google.com/drive/1EG1V40v5xkJKLf6Ra6W...
What sets DeepFabric apart from other dataset generation tools is its ability to ensure high diversity yet domain-anchored relevance through unique topic graph generation algorithms. This guides sample creation to cover all necessary subtopics while avoiding redundancy, which is where other tools often fall short, resulting in model overfit.
Constrained decoding and response validation, along with real tool executions within isolated webassembly environments, ensure that generated samples strictly adhere to structured schema, variable constraints, and execution correctness, ensuring datasets have exact syntax and structure for use in model training pipelines. Tool definitions can be directly imported from MCP server schemas and then mocked, or rans as real life tool functions. Using real tools means the model has to adapt and correct when it makes the wrong choice or hallucinationates which makes for much better training data.
Once your dataset is generated, it can be automatically uploaded to Hugging Face and directly imported into popular training frameworks like TRL, Unsloth, and Axolotl.
Post-training, DeepFabric's built-in evaluation engine assesses model performance, whereby models prove their capabilities on unseen tasks derived from training splits—covering evaluation-only questions, answers, and tool traces.

#13https://PostalAgent.com – Send personalized postcards online.
Upload a CSV or circle neighborhoods on Google Maps to build your address list (consumers or businesses). Printing and postage included in one price.
In the last 30 days I've added integrations for Zapier and Jobber (after adding Pipedrive, Zoho, and Follow Up Boss last month).
If anyone wants to help test these new integrations, I'll set you up on a special plan and let you send mail at my cost (roughly the price of a stamp)

#14An app for my local bulk grocery shop to detect what is inside each glass jar to improve the checkout process.
There is no barcode as you bring your own glass jar and you fill it with pasta, rice, sugar ect.
The manager wastes too much time looking at what's inside and typing the code into his till

#15My new video synthesizer app for iOS. https://www.chromatose.app For creating & performing unique visuals on the go. Freemium w/ access to all features (just a 2 patch save limit).
This looks beautiful! I'm excited to play around with it and see what I can make!

#16I just launched the beta of my app that uses Elixir/Phoenix. Its a community driven aggregation of technology resources for Michigan, like companies in Michigan that hire tech talent, university programs, incubators in Michigan, etc. It also includes a newsletter thats already fully live and has over 10 subscribers. I'm gathering starting data and feedback now!

#17A hot reloadable menu library for raylib / raygui applications in Zig.
https://github.com/pajanowski/raymenuz
I want to use this for future raylib games as a developer menu.
I wanted to learn more Zig and be able to add or remove game state fields to and from the screen without having to recompile.

#18We’ve optimized the internet for producing information, not for humans consuming it. Most of us are overwhelmed not because content is bad, but because it’s all delivered in the same rigid format.
I’m working on unrav.io : a way to reshape any web content (article, video, or PDF) into the form that actually fits how you think (summaries, mindmaps, infographics, podcasts, chat, etc.).
We just launched a Chrome extension, so it’s one click on any page. No login, free to try.

#19I built an LED globe with a world viewing portal that uses a raspberry pi and pre-generated AI videos of places around the world. I'm working on upgrading it to do realtime generation of the videos and to improve the hardware so it is more durable and capable of being hauled around for community use.

#20I've been learning the basics of using Z3 by creating a solver for the daily puzzle game Clues By Sam (very fun game; https://cluesbysam.com/). Repo is https://github.com/DylanSp/clues-by-sam-solver. It uses Playwright to read clues and submit guesses; I've got it working for all 50 puzzles in puzzle pack 1.
