Built a tiny high-performance telemetry/log tailing agent in Zig (epoll + inotify). Feedback & contributors welcome

I’ve been hacking on a little side-project called zail — a lightweight telemetry agent written in Zig that watches directories recursively and streams out newly appended log data in real time.

Think of it like a minimal “tail-F”, but built properly on top of epoll + inotify, no polling, and stable file identity tracking (inode + dev_id). It’s designed for setups where you want something fast, predictable, and low-CPU to collect logs or feed them into other systems.

# Why I’m posting

I’m looking for early contributors, reviewers, and anyone who enjoys hacking on:

epoll / inotify internals
log rotation logic
output sinks (JSON, TCP/UDP, HTTP, Redis, etc.)
async worker pipelines
structured log parsing
general Zig code quality improvements

The codebase is small, easy to navigate, and friendly for new Zig/system-level contributors.

If you like low-level Linux stuff or just want a fun project to tinker with, I’d love your thoughts or contributions!

What open-source project should i enter to?

For context, I use Fedora as my OS. I currently work with JavaScript, and I want to join an open-source project to learn, contribute, and help. I love CLIs, TUIs, and those kinds of things. Does anyone know a project?

Prism — open-source, TS-first package registry (contributors wanted)

I’ve launched Prism, an open-source package registry built with TypeScript and Fastify.

Goal: a modern superset registry on top of npm.

Project is early and open for contributors — architecture is clean and fun to work on.

Do I Need to Show MIT License Attribution in My App’s UI After Forking a Project?

Hi,
If I fork an MIT-licensed project and publish my own customized version, is it enough to keep the original MIT license file inside my project repository?

Am I allowed not to display the license or attribution anywhere in the user-facing UI (like an About page or Legal page on my website), as long as the license remains unchanged in the codebase?

Just want to confirm if this is compliant with MIT license requirements.

Can I use WASM for DOM manipulation?

I don't know the answer.
Looking for answers for this.
I am working on a product that needs this.

So, what's your thoughts?

DataOps - a free, open-source browser tool for working with data and PDFs (no uploads, everything stays local)



My friend has asked me to post this on reddit, he says:

"Hey everyone!

I’ve been working on DataOps, a browser-based tool for common data and PDF tasks. Everything runs locally in your browser - no uploads, no servers, your files never leave your device.



It handles JSON/XML/TOON comparison, conversion and formatting, PDF merging/splitting, API testing, Base64 encoding, and more. Works on mobile too.



I built this because I was tired of sketchy online tools that make you upload sensitive documents like personal (passports) or company documents/data to unknown servers.

It’s completely open-source and free to use. No account needed, no tracking.



Try it here: https://dataopsapp.com



Would love to hear your feedback or feature

requests!"

UnisonDB - Log-based real-time database

Log-native real-time database : Designed to solve data consistency and real-time responsiveness challenges

* Combining a B+Tree storage engine and Write-Ahead Logging (WAL) -based streaming replication, it ensures sub-second replication and strong consistency across hundreds of nodes.
* Supports Key-Value, Wide-Column, and Large Object (LOB) storage with a multi-model structure
* Optimized for local-first architecture with edge-first design
* Multi-tenancy support through namespace isolation

Differences from existing systems:

* LMDB/BoltDB is a fast local storage but cannot be replicated.
* etcd/Consul has high consistency but limited scalability.
* Kafka/NATS is strong in streaming, but not queryable.

UnisonDB bridges this gap, providing a single, log-centric architecture that integrates storage and streaming.

Core architecture 3-tier structure

1. WALFS (Write-Ahead Log File System) * – mmap-based log file system, optimized for large-scale read/write
* Segment-based log structure, optimized for both sequential writes and random reads
* Supports zero-copy reading , offset-based seeking , and real-time tailing
* Parallel reader architecture that allows multiple replica nodes to read simultaneously

2. Engine – Hybrid storage combining WAL, MemTable, and B-Tree
* Combination of MemTable (skip list) and B-Tree index based on WALFS
* Transfer without deserialization when replicating using FlatBuffers
* Supports atomic multi-key transactions , ensuring consistency at the commit level.
* LOB (Large Object) can be chunked and streamed in units of transactions.
* Wide-Column model supports partial column updates and dynamic schema expansion.

3. Replication – WAL-based streaming replication, including offset tracking.
* WAL-based streaming replication , where followers track offsets and synchronize in real time.
* Maintain self-describing data structures using FlatBuffer log records .
* Efficient streaming implementation with batch transmission
* Consistency-focused design

UnisonDB's solution
* Append-only log + B-Tree combination provides high-speed writes and efficient range reads.
* Support for transaction-based multi-key replication and column-aware synchronization
* Built-in replication with gRPC WAL streaming + B-Tree snapshots

Seeking feedback on my experimental js lib oem

I've been building and rebuilding a framework off and on for a couple years. I recently had an ah-hah moment and reworked things to a 2.0 version. I just posted the new version here: https://oem.js.org/. I'm curious what people think. The core idea is that it's a framework to design your own framework. It's only 300 LOC and it facilitates a particular syntax for your own framework that results in code you can understand from top to bottom.

Writingway 2: Scrivener meets AI-integration

I wrote a freeware version of sites like NovelCrafter or Sudowrite. Runs on your machine, costs zero, nothing gets saved on some obscure server, and you could even run it with a local model completely without internet access.

Of course FOSS.

Here's my blog post about it:
