Flowgramming – Programs that read like sentences

Most programming languages were built for machines first and humans second.
Flowgramming flips that.

It’s an open-source project to design a modular, flow-based programming environment where logic reads like natural language.
Instead of writing syntax, you describe what should happen — and FlowOS builds the logic through modular, auditable components called FlowBlocks.

For example, this is valid FlowScript:

action:
intent: "sortlist"
input: "DataBlock: numbers.raw"
output: "DataBlock: numbers.sorted"
tags: [lowmemory, auditable]


That line means:

>

Flowgramming handles the rest — picking the best ActionBlock, enforcing memory and security rules, and logging the entire process for audit.

The full system includes:

FlowDirector — the runtime and scheduler
ActionSystem — modular, self-contained logic units
CommSystem — controlled communication blocks
DataSystem — trusted data handling and versioning
FlowGuard — built-in trust and security enforcement
FlowLog — transparent observability and audit trail

It’s licensed under MPL 2.0, so it stays open but flexible for research or enterprise use.
The documentation is being expanded weekly — early contributors are very welcome.

Flowgramming is still early — but the goal is simple:
make programming something you can read, explain, and trust.

Rivet.dev

In looking for durable object's open source alternatives. After search for a while, I found rivet.dev.

Did someone ever use this project, it's quite an interesting project with tons of stars. But looking at the npm download, it's like no one using them.

How do you manage bad code reviews on your open source project?

So I have a small project which has picked up some users and a small GitHub following.
Every few months I get the odd PR.

The most recent one was to add config to determine which columns to show in a table in the application.
The application already has a config file, which is in yaml. The PR proposes using a single string with template syntax to determine which columns to show; my preference would be to just use a list of booleans as it's more clear.

I suggested this, and the person who raised the PR replied with a GenAI generated comment weighing up the pros and cons of each, then updated the PR to do both which I feel is unnecessary and makes it more messy and sufficient to understand.

How do people go about dealing with stuff like this? If this was at work, and the PR came from someone who works for me, I would just have a chat and ultimately would have the power to make a final decision. Ultimately I can decide whether or not to merge this, but it feels different with volunteers. I don't want to seem a dick, but I also don't want to merge some garbage, and then have this in my name on my public GitHub.

Any thoughts/advice? Both about this, but also in the general case?

Meet Journiv — A self-hosted private journaling & mood tracker (Day One / Apple Journal alternative)

Hey folks!

I got into self-hosting last year. While exploring, I noticed there’s no real self-hosted open source equivalent to **Day One** or **Apple Journal**. Most suggestions were note-taking apps or older abandoned projects — not quite what I wanted. I specifically wanted "On this day" and prompt based journaling experience with a clean and minimal writing interface.

So I built my own: **Journiv** — a private, self-hosted journal and mood-tracking app.

Demo video: [https://imgur.com/a/Z5oBMgU](https://imgur.com/a/Z5oBMgU) (subreddit does not allow video attachment)

**Stack**

* **Backend:** Python + FastAPI + PostgreSQL (Dockerized)
* **Frontend:** Flutter (cross-platform web + mobile)

**Features**

* Clean, minimal, distraction-free writing
* “On this day” view
* Prompt-based journaling
* Mood tracking
* Multiple journals + tags
* Full-text search
* Insights & analytics
* Light/dark mode
* Media gallery view

**Coming soon**

* Quick audio notes
* Apple Journaling Suggestions integration
* Weather & health metadata
* Location tagging (map view for travel entries)

I’m planning to open-source this soon and would love some early feedback first. Curious if folks here would find a self-hosted journaling app like this useful — and what features you’d want to see. It’s my first real project in Python + Flutter, so there are definitely a few rough spots. Early testers and feedback would mean a lot!

Trained the first foundation model for a low-resource language

Hi everybody! I just wanted to share a project that I have been working on for the last few months called BULaMU, the first large language model that has been trained from scratch in Luganda. It is an open-weight model and is available to download for free from my Huggingface repo. I am continually working to improve BULaMU because I believe that tiny language models like this have the ability to greatly broaden access to AI in Uganda and possibly even enable more community-driven solutions.

Details on how I trained BULaMU: https://zenodo.org/records/17271688

[WIP] Screen Studio Open-Source Alternative

Hey everyone 👋

I’ve been working on [ScreenArc](https://github.com/tamnguyenvan/screenarc) — an open-source & cross-platform (Linux, Windows, macOS) screen recording \*\*and editing\*\* app inspired by apps like Screen Studio.

It’s built with \*\*Electron + React + FFmpeg\*\*, and the goal is to eventually reach that same **cinematic quality and smooth experience**, but fully open source.

✨ \*\*What it does\*\*

* \*Tracks your mouse automatically and adds smooth \*\*pan & zoom\*\* animations
* Includes a simple \*\*timeline editor\*\* to trim, adjust backgrounds, shadows, or aspect ratios
* Lets you \*\*export high-quality MP4/GIF\*\* with just a few clicks
* Works on \*\*Windows, macOS, and Linux\*\* (yep, cross-platform!)

🎥 Here’s what it looks like in action:

🧱 \*\*Tech Stack:\*\*

* Electron
* React
* TailwindCSS
* Zustand
* FFmpeg

🚧 It’s still a work in progress — a lot of polish and features are on the way, but it’s already functional enough to play with.

If you’re into open-source tools for content creation or you love building creative desktop apps, check it out and maybe drop a ⭐️ on GitHub!

Hi all!

I've worked on songfetch as a fun Python side project for a couple of weeks, and here is the result!
I haven't found any existing ones that shows actual ASCII art, and not just pixelated version of album covers, so I hope this post is allowed!

It's available on the AUR, you can also check it out on GitHub:

Snip - The Command-Line Note-Taking Tool I Built Because I Was Tired of Slow Apps

\## TL;DR

I built Snip because I was frustrated with slow note-taking apps. It's a command-line tool that's fast, local, and actually works. No AI, no cloud, no BS - just you, your terminal, and your thoughts.



\---



\## The Problem That Drove Me Crazy



Picture this: You're debugging a complex authentication issue at 2 AM. You have a brilliant insight, but every note-taking app you try is either:

\- Too slow to open

\- Requires you to leave your terminal

\- Wants you to create an account

\- Has a bloated interface that gets in the way



Sound familiar? (If it doesn't, i envy you) This happened to me way too many times. As a developer, I live in my terminal. Why should I have to leave it just to write down a thought?



\---



\## What I Built



Snip is a command-line note-taking tool that respects your workflow. It's built with Go, uses SQLite for storage, and gets out of your way. Think of it as your personal knowledge base that lives in your terminal.



\### The Core Philosophy

\- **Fast**: No waiting, no loading screens

\- **Local**: Your data stays on your machine

\- **Simple**: No accounts, no subnoscriptions, no complexity

\- **Terminal-native**: Works where you already are

\---

\## Why This Matters



\### For Developers

You're already in your terminal. Why leave it just to write down a thought? Snip lets you capture ideas instantly without breaking your flow.



\### For Writers

Quick idea capture, organized with tags, exportable to Markdown. Perfect for anyone who thinks in text.



\### For Students

Lecture notes, study guides, quick references. All searchable, all local, all fast.



\---



\## The Technical Story



I built Snip with Go because I wanted something that would be:

\- **Fast to compile**: No waiting for builds

\- **Cross-platform**: Works on Windows, macOS, Linux

\- **Self-contained**: No external dependencies

\- **Reliable**: Go's error handling keeps things stable



The database is SQLite with FTS4 for full-text search. It's not the most sophisticated setup, but it works. And that's the point - it works.



\---



\## What Makes It Different



\### Not Another Note App

Most note-taking apps are designed for everyone. Snip is designed for people who think in text and live in terminals.



\### No Lock-in

Your notes are stored in a local SQLite database. Export them anytime. Import from anywhere. You own your data.



\### No Complexity

No accounts, no sync, no cloud. Just you and your notes. Sometimes simple is better.



\---



\## The Real-World Impact



Since building Snip, I've:

\- **Captured ideas faster**: No more losing thoughts while switching apps

\- **Stayed in flow**: No context switching when debugging

\- **Organized better**: Tags and search make finding things easy

\- **Backed up easily**: Export to Markdown, import anywhere



\## What's Next



I'm not done yet. Here's what I'm thinking about:

\- **Markdown Preview**: Visualize rendered Markdown so you can see your notes as they'd appear formatted



\---



\## The Story Behind Snip



I've been a developer for years, and I've always struggled with note-taking tools. They're either too slow, too complex, or too locked-in to specific platforms.



One day, I was debugging a complex authentication issue, and I needed to quickly jot down some thoughts. Every tool I tried was either too slow to open or required me to leave my terminal. That's when I realized: developers need a tool that lives in their terminal.



So I built Snip. Not just another note-taking app, but a developer-first tool that respects your workflow. It's fast, it's local, and it gets out of your way.



\---



\## Why I'm Sharing This



I built Snip to solve my own problem, but I think other developers might find it useful too. It's open source, it's free, and it's built by someone who actually uses it.



If you're tired of slow, bloated note-taking apps, give Snip a try. It might just

change how you capture and organize your thoughts.

Any good open-source offline Postman alternatives worth trying?

I’ve been looking into Postman alternatives, especially ones that can work offline or be self-hosted. I came across a tool called Apicat that seems to handle OpenAPI and Postman imports while working completely offline, which caught my eye.

I’m curious are there any other open-source or self-hosted Postman alternatives you’d recommend? Would love to hear what’s been reliable for your workflow.
