I’m working on a cross-platform fast multithreaded HTTP / FTP downloader that will download much more quickly than other clients like FileZilla, hash check files, perform follow up operations (like extracting RARs or deleting files on the remote,) and have a nice graphical UI that runs in the browser and allows local/remote/cloud control.

I made a small and light CRUD web thing in FastAPI to organize my personal library. Mostly it focuses on physical books, but handles ebooks too. I published it as FOSS and some people requested features, so I expanded it a little. It's nothing fancy: https://github.com/seanboyce/ubiblio
...absolutely no one requested an RISC V port, but I did that too for laughs. Neat to see the whole thing run on a system the size of a postage stamp.
Not sure what to do with it next. Will probably just let it be what it is, and fix any bugs that people report. Maybe move on to a new little weekend project.

I have been working full-time for about 15 months on a product to store real-world entity-relations in a graph (using AI/ML for extraction). The idea is to extract entities and relations deterministically from text (using AI/ML for clues about type and position of entities in text).
It is very much a work in progress with lots of commented out code which are just experiments.

Docker configurations for running different AI projects (SD, LLMs) on ROCm devices
I've been dabbling with local ML projects, and trying to get them to run with ROCm on my Radeon 7900 XTX card. All the solutions to run for example Llama.cpp or Automatic1111 are a bit hacky, so I made a repo where I document how to run them in containers.

Taskusanakirja. A tiny, fast, portable Finnish-English dictionary, which searches as you type. (by hiAndrewQuinn)
I continue to spend most of my free energy learning Finnish. Only a few more years and I should be able to finally focus on my career again :')
Two new projects of note this month, one specific to Finnish language learners, and one that is probably useful for language learners in general:
* https://github.com/hiAndrewQuinn/tsk - A Finnish pocket dictionary with a TUI interface. This is the first nontrivial thing I've built in Go, by which I meant I had to implement and tweak a randomly pruning trie by hand to get the performance characteristics I wanted (it wasn't actually that bad). I chose Go mostly because of the fantastic cross-compilation story.
* https://github.com/hiAndrewQuinn/audio2anki - This Python program wraps around `yt-dlp` and `whisper` to create Anki decks for listening practice. This should work for any (monolingual) video in any language. There are many such projects on GitHub, I'm aware, but it was surprisingly hard to find any that actually wrapped around Whisper instead of needing an SRT, VTT, etc file to come from somewhere else. In that sense mine is a "one command" solution - just provide the YouTube link and go.

I've been building https://canine.sh for the past year, which is an open source Render / Fly / Heroku, etc.
It's based on some learnings I've had in the past building where building on managed platforms like Heroku and Render, and watched our costs explode, with an annoying amount of vendor lockin.
It uses Kubernetes under the hood (which you can now get fully managed for $12 / month on linode), which lets you take advantage of a ton of things that Kubernetes does really well, like automatic healthchecks, zero downtime deployments, auto scaling, etc, while also making it easy to use for solo developers or small teams.
The additional benefit of Kubernetes is that it's also possible to host a bunch of other stuff in your cluster via Helm charts, that you’d normally have to pay for like: Sentry, Wordpress, Postgres, etc.

Thanks! I built the editor using Tiptap (https://tiptap.dev/) which doesn't support Markdown out of the box. However, since it can detect Markdown shortcuts (#, ##, >, etc.), it should be possible to convert a markdown file into rich text, and then when done writing and editing convert it back into markdown, while limiting formatting options only to ones that are available for both. I think Joplin (https://joplinapp.org/) does something similar.
I'll think about this for sure, especially since I've been thinking of making it possible to save and read local files. If you'd like to try Gorby, send me an email and I'll be happy to give you a free license code :)

The first open source MMP https://openattribution.dev
MMPs collect user data across apps to help apps run ads. This is needed because mobile apps are downloaded without the additional data you could get passed along an HTTP url like you'd see in a regular email marketing campaign or YouTube affiliate link.
My goal is to create a way for mobile apps to self host their advertising attribution, keeping their user data in house and not sharing it to a 3rd party like AppsFlyer/Adjust/Branch. There are only a few companies that do this in the world and NO open source non 3rd party option.
Please reach out if interested, I'd love to chat!

FreeCAD
This is the official source code of FreeCAD, a free and opensource multiplatform 3D parametric modeler.
I'm a long-time FreeCAD user, and one of my annoyances is that long-running operations lock up the entire UI and can't be aborted.
So for my first contribution to FreeCAD I'm working on fixing this.
The underlying CAD operations are done by "OpenCascade", and at first I thought OpenCascade had no support for aborting operations part of the way through. So my first implementation was to move the operation into a child process and give the user a dialog box that would allow terminating the child process.
But it actually turns out OpenCascade does support aborting the operations! So now I'm working on doing it the OpenCascade way.
My PR is here: https://github.com/FreeCAD/FreeCAD/pull/19796

A web-native[1] protocol for secure[2], decentralised[3] access to files distributed across mirrors:
1. "Web-native" as in the protocol is designed with HTTP and modern web browsers in mind. Consequently, it can be implemented using Service Workers so that no additional software (nor even browser extensions) are needed to access files.
2. Files are addressed by their cryptographic hash of their content (a) to ensure the authenticity of the data received from mirrors and (b) to avoid hard-coding specific locations/servers (i.e. content addressing).
3. Files can be mirrored by anyone and users can retrieve files from any mirror; no party requires any permission from any authority. This is in contrast to traditional mirroring schemes, where mirrors have to "register" with the owner of the content (e.g. to mirror a Linux distro).
Demo: https://webmirror-demo.netlify.app/
Code: https://gitlab.com/webmirror/webmirror/
Work in progress!

I've been working on https://github.com/nickjj/plutus, it's a command line income and expense tracker.
It generates reports to show you your numbers in a bunch of customizable ways, it generates these reports in less than a second and uses a single CSV file as your data source.
I've gotten things to the point where I can do my books every quarter in about 5 minutes with complete accuracy since it supports importing arbitrary CSV files such as bank exports with a way to automate categorizing things in any way you see fit.
Basically I ran into issues using different finance tracking tools over the last decade which always made me feel unhappy to use those tools so I built Plutus to no longer make compromises.

uncloud
A lightweight tool for deploying and managing containerised applications across a network of Docker hosts. Bridging the gap between Docker and Kubernetes ✨
Working on https://github.com/psviderski/uncloud (https://uncloud.run) — think Fly.io but self-hosted. A lightweight Docker clustering tool for running web apps on your own servers (from cloud VMs to bare metal) with no control plane to maintain. Perfect for teams who want cloud-like deployments without Kubernetes complexity. Early days but seeing promising results with eventually consistent state sync, zero-config mesh networking, and automatic HTTPS ingress.

OpenPythonSCAD library for moving a tool in lines and arcs so as to model how a part would be cut using G-Code or described as a DXF.

https://github.com/WillAdams/gcodepreview
Writing it in a TeX editor using a Literate Programming system developed in the course of working on it, the PDF should give both a good overview, and provide all the code.
It has greatly expanded/restored my math/geometry and has me looking forward to how to implement Bézier Curves and surfaces using similar math (since G-code and CGAL are fundamentally limited to lines and arcs and what can be easily made from such constructs).

1. Hackable text input system := Hatis https://github.com/shegeley/hatis
«Text-editors are dead as a concept. What’s needed is a text-input system. Mobile phones got it right more than 10 years ago. Both Android and iOS can catch the text-input context: «ah here we can input text, let’s show the virtual keyboard!».
This project is inspired by very same idea: catch the text-input context globally (across all system, not just one process) and do what’s needed: change the UI, keybindings, etc. Emacs got some part of text-input right with modes. But modes should be global, on Window Manager level (or even deeper).
In GUI it’s possible to “catch input context” using Wayland::InputMethod
It should also be possible on pure-tty with readline or something.
The system should be very hackable. That’s why it’s written in Common Lisp»

I'm exploring the world of Tauri cross-platform desktop apps in my free time now.
For the first project using this technology I decided to go for a simple media converter app. I have a 64MB sampler so I have to convert a lot of samples from lossless formats to mp3, there are two options I know: any random online tool from the google page 1 or ffmpeg cli. The former almost physically hurts, because I have to upload my files to some server which does the same ffmpeg instruction and then get them bytes back, that's a heck of an overhead!
ffmpeg-cli and some knee-made bash scripts is what I have been using for a long time. I love my console, and I spend 90% of the time inside, but then it comes to ffmpeg, it instantly feels tedious to use it. Finally I decided to make yet another GUI wrapper:
https://github.com/ilya-lopukhin/conversimp
The idea is to drag the files in, or select them via dialog, then run an ffmpeg conversion template with each file as input in a separate thread (need to limit theese btw). I decided to go fully open-source, and maybe promote it's usage over the online ad-farms which are really abundant. When I decided to publish this, I instantly understood it's going to be a tons of extra work, but in the end I want it to look nice and do it's job flawlessy, and at the moment it's a weekend or two from release.
Let me know what you think ;)

I'm working on Airweave https://github.com/airweave-ai/airweave , an open-source dev tool that makes any app searchable for AI agents. it connects to a source app, db, or api and converts its contents to accessible knowledge for agents. Airweave automates authentication, ingestion, enrichment, mapping, and syncing to vector stores and graph databases of choice. you can use it via our UI, API, or SDKs https://docs.airweave.ai/
we originally built this for our previous agent startup as an internal solution to ensure agents could find the relevant data on apps they're using. We then pivoted to this after some early positive reactions and decided to open-source it.
here's a short demo: https://tinyurl.com/demo-airweave
we're two engineers/friends based in Amsterdam, NL. We just launched the project, so it's rough around the edges ofc, but we're very eager to get some feedback!

buckaroo
Buckaroo - the data wrangling assistant for pandas. Quickly explore dataframes, and run pandas commands via a GUI. Works inside the jupyter notebook.
I am building Buckaroo [1], the data table UI in Jupyter that I have always wanted. I know how to use df.head(), df.describe(), sort, and run histograms on columns. I just got tired of typing 5 bits of code to minimally inspect each dataframe every time I looked at it.
So I built buckaroo, it combines a high performance scrollable table (built on top of ag-grid), with summary stats, and histograms. All of this is customizable and extensible. I recently built a dataframe compare tool [2] on top of buckaroo that uses coloring to show differences between dataframes intuitively.

I'm building a stream processing framework using DuckDB.
https://github.com/turbolytics/sql-flow
The goal is to create a stream processing framework that supports SQL jobs. Apache Flink supports this but is very heavy-weight overall. I work with cost constrained companies that just can't run Flink but still want access to high performance streaming primitives.
We are taking a slightly different approach from other competitors by building cloud-native tools for engineers. SQLFlow is built on DuckDB, Native Kafka Library, and Arrow. This allows SQLFlow to handle ~70k+ events / second with low memory overhead (~250MiB).
Would love your questions, thoughts and feedback or feature Ideas! Thank you

Scrawl-canvas
Responsive, interactive and more accessible HTML5 canvas elements. Scrawl-canvas is a JavaScript library designed to make using the HTML5 canvas element easier, and more fun
I'm writing a Developer Runbook[1] for my JS canvas library.

But mainly in the vague hope that maybe the extra data will help our new LLords and Masters make less stupid decisions when they make code suggestions to innocent developers on how to use my library in their code.

I'm working on a text editor (https://github.com/blackhole89/autopen/) that continuously analyses the buffer with a local LLM to compute token surprisal and generate candidate completions starting from any point, and switch back and forth between different ones by walking a tree structure. This is pretty different from the usual way people interact with LLMs, and has lots of interesting applications - for example, if you are using them to translate and don't like a particular word choice, you can "dig through" top alternatives on the spot or even insert your own.
Applying the same approach to chain-of-thought reasoning gave me the feeling that I might be looking at a form of realistic UX for some sort of science-fiction neural AI augmentation - you can let the CoT run on and do its thing, but also interject at any point and insert a "thought" of your own, or go back and revise a thought you did not like, and then let it continue. Imagine such a stream hooked up with a two-way pipe into your phonological loop (https://www.sciencedirect.com/topics/psychology/phonological... - perhaps more attainable with existing tech).

paranoia
A secure, self-hosted tool for sharing secrets that vanish after a single view. Quickly transfer sensitive information with end-to-end encryption and one-time access, giving you full control over your data. (by jonesconnor)
I'm developing ParaNoia, an application that allows people to securely share passwords between each other (https://github.com/jonesconnor/paranoia).
At my organization, we have a corporate-approved password manager, but shared folders are disabled. If someone needs a FID password, or something of the like, there are people that send the password in plain text over Slack, Teams, etc. and not everyone deletes their message containing the password afterwards.
You enter your secret on the website and it gets encrypted on the client-side before being sent to the database. A one-time-use URL is generated and then you send that URL to whomever needs the password. The backend never sees the secret in plain-text.
The tool is meant to be self-hosted - but I'm in the process of deploying it publicly for people to try out. I got the idea from my brother -- he was doing an internship at Tesla and said they had this being used internally, so I figured I would create my own as a little side project that I can then implement at work.

shodohflo
Pure Python netflow and DNS correlation, with reusable Frame Streams, DnsTap and Protobuf implementations
I've been working on something I call "Poor Fred's SIEM" (a play on Poor Richard's Almanac) for several years, rethinking an approach to observability based on the functional difference between diagnostic and evaluative observables: cooking evaluatives at the edge, presuming that diagnostics will be investigated on the (well-implemented) network segment where they are recorded. I've also rethought PTR records based on local knowledge, dovetails quite nicely. Living off the land: redis, python + dnspython + dpkt, DNS as both observable and transport.
The core components are on GitHub:

Not the first time I've referenced these on HN. I did just implement a Redis operator which Redis doesn't have, SHARDS:
* https://github.com/m3047/rkvdns/blob/main/SHARDS_Command.md
No GUI, command line tools work for me. I've got a toolkit. I don't give it away because I don't want to support it but if you made friends and asked nicely I'd toss it your way. Here's a silly little two minutes of your life... done in one take, in Skype:
* https://www.zipcon.net/~m3047/observability-dream.mp4
I actually eat this dog food to the point where I publish (some) telemetry data on the internet with this toolkit using DNS. Again, make friends and I'll tell you where to find it. I think it would be great if other people ran this toolkit and published telemetry data for other edge operators to see: things can be federated, they don't need to be centralized.

> For the 1st point, I generate a script with hashed check points so next run is automated unless something changes in the UI to invoke AI. I make this possible by proxy wrapping playwright library so I can take over every method. Users use playwright like they always have but with one extra method called act.
How would you determine that something changed in UI by just looking at a screenshot? Would you additionally compare HTML/DOM or approximate the two screenshots?
> Omini parser lets you split section of the UI to hash and watch for changes that are relevant.
I wasn't aware, thanks for sharing!
> For 2, can you give some examples?
Specifically, if you take the Shortest tool (https://shortest.com), a test runner powered by Computer Use API, write a test "Validate the task can be pinned" for https://todomvc.com/examples/vue/dist/, and run it — it passes. It should have failed because there is no way to "pin" tasks in the app, yet it pretends that completing the task is the same as pinning.

Yes, that is a big part of the design choice for this language. I felt that circuit elements are usually defined in relation to other circuit elements and instead of explicitly stating connections, it might provide more understanding of the overall circuit if the user builds the connections by "walking" along the circuit graph. A good side effect of this is that you skip having to name every single component in the circuit.
I was inspired by skidl (https://devbisme.github.io/skidl/)'s python usage and did explore that direction. However, it felt strange and clunky to try and fit the circuit drawing concepts I had in mind into python via a domain specific language (DSL). The user would require a decent understanding of python and the DSL to create circuits. This would complicate my original aim of creating a language/tool that allows electronics engineers to focus on the circuits that they would like to design.
By creating a new language, I was not limited by python's syntax/grammar. I could craft the language closer to what was needed for schematic design and maintain simplicity. Overall, it was a great learning experience on language design and also using ANTLR for the implementation.

Been working on a platform for applicants to find out who is applying to the same job and whether we got ghosted.
It was frustrating to apply for jobs, with no rejection emails and no updates, not knowing whether to keep waiting or move on. The plan is to answer questions like:
1. Has anyone heard back from this role?
2. How long does it usually take to hear back?
3. What are the online assessments/interview rounds like for company X.
