GitGuard (https://gitguard.dev)

Basically it’s a way to enforce custom policy rules on GitHub PRs without writing any scripts or maintaining any custom Actions. It’s got all of the customization that you wish GitHub’s built in branch protections had.

Things like “make sure the frontend tests pass if there are frontend code changes” or “require 2 approvals only if there are no test files added” are trivial to write and enforce.

I'm continuing to update my already published ebooks. Apart from catching up to new software versions, it also helps to address typos and other issues found by my readers.

Last week I published a new version for my awk ebook (https://learnbyexample.github.io/cli-text-processing-awk-ann...) and today I'll start working on sed ebook.

I am working on a FOSS google tasks alternative for android with unix-like aesthetics and my desire to take some inspiration from the windows mobile app designs. It's just 84kb apk at the with reproducible build system and also downloadable from IzzyOnDroid fdroid repo: https://apt.izzysoft.de/fdroid/index/apk/io.github.ronynn.ka...

It's privacy focussed and does not connects to the internet, your notes stay on device which you can backup and import into other devices, and I am working on a quick qr share features too.

My idea was that there are almost no android apps with this kind of design vision even though there are fans of this design out there as can be seen with the trend of people modifying their termux startup screens and the huge downloads of windows mobile styled launchers. And so I want to make a design system that provides an open source go to system for others to make apps with this design

I am continuing work on https://reliquary.se - a VPN for the hackers - based on my fully privilege separated and sandboxed VPN sanctum (https://sanctum.se).

It is shaping up nicely towards an actual 1.0 release in the near future, with a little less keccak based AEADs this time around. It was a fun experiment but in the end I have yet to do any cryptanalysis on it or provide security proofs for it - neither which I have time for at this point - so the swap to AES was expected on my end.

For fun I also added a fully e2e p2p voice chat client on top of this as the sanctum protocol is now available as a library (https://github.com/jorisvink/libkyrka) - this voice chat works with one or multiple peers and can is available at https://github.com/jorisvink/confessions.

Either way, I guess you can say I'm having a little bit too much fun with this.

We're building https://tripjam.com after being frustrated with planning trips in regular group chats and trying to organize information across multiple apps. It combines:

- Group chat that keeps all travel discussions in one thread

- Interactive maps where everyone can pin locations and add notes

- Collaborative itineraries that sync with your calendar

- AI travel assistant that suggests activities and helps optimize your plans

I couldn't find your Privacy Policy so I didn't register. Did I miss it?

Should be linked at the bottom of our landing page. Thanks for taking a look!

Got it, thanks. I appreciate no data is shared with third parties. Good on you.

I'm working on DeskPal. The project still needs a lot of polishing, so it's in private for now. Here is a part of its README. # DESKPAL

## What is DeskPal? DeskPal stands for Desktop Companion - exactly as it sounds: A companion for your desktop.

It's a gadget that will: - Display your media info (From Spotify, etc. - more sources to be added) - Display time - Connect to your phone and display notifications (TBD) - Function as a StreamDeck-like device (TBD)

All of these features should work right out of the box, without installing any new apps on phone or computer: - You can use it with your company laptop, or even with no computer at all - An app may be needed to configure some settings (like StreamDeck macros - TBD)

## Hardware & Software Inside DeskPal is an ESP32S3 MCU that supports both WiFi and BLE. The current configuration has 16MB Flash memory and 8MB of SRAM.

DeskPal runs on Zephyr RTOS, a RTOS that is heavily supported by many vendors. Using Zephyr allows us to leverage a vast ecosystem of hardware drivers and enables easy porting of this project to other MCUs if needed.

DeskPal's software architecture allows adding dynamic apps so that we can install or remove functionality without firmware updates.

- Semi-automated job finder for a job site focused on non-mainstream programming languages [1]. - Eiffel-inspired programming language [2].

It's hard to juggle between the two.

Very nice on both! I've long had an affinity for non-mainstream programming languages (mostly those with Wirth lineage). I wish there were more projects that used them.

I'm building pgflow, a Postgres-native workflow orchestration engine that keeps the entire DAG's state and orchestration logic inside the database, while a dedicated task queue worker (Edge Worker) handles execution.

This split minimizes external dependencies and makes it easy to manage complex pipelines without leaving PostgreSQL.

I started pgflow because I wanted a fully integrated, Supabase-based system (no separate servers!) for reliable, parallel workflows which keep state in postgres so I can trigger flows from triggers and stream their progress via Supabase Realtime.

Started protytyping it in early November, released serverless task queue worker in January and I'm currently polishing the flow orchestrator pieces, releasing an alpha version in upcoming weeks.

If you're curious:

- More on Twitter/X: @pgflow_dev (https://x.com/pgflow_dev)

- Edge Worker docs (will get flow orchestration docs included soon): https://pgflow.dev

Reddit updates:

Happy to discuss or collaborate if anyone's interested!

I'm learning FreeCAD and 3D printing. My goals are to be able to print involute gears, and eventually various mechanical arithmetic devices, leading up to a mechanical version of my BitGrid. Also, I want to make an Armstrong shaper.

A friend gifted me a large box of semiconductors, and I'll be testing 7400 and 4000 series chips for the next week once my T48 EPROM Burner/IC tester shows up.
