IronCalc is a new open source spreadsheet engine written in Rust with bindings in Python and JavaScript. The engine can be compiled to wasm and runs in the browser.

Pitch:

https://www.ironcalc.com/

Playground:

https://playground.ironcalc.com/

Source Code:

https://github.com/ironcalc

IronCalc intends to be robust, light, fast, easy to use and Excel compatible.

Although IronCalc is already working there is still a long way to go. We want to build different skins like native apps, terminal applications. We need to incorporate all Excel functions. We want to add charts like maybe chartjs

The current skin is written in React/TypeScript.

SearchWing is a german based (berlin,augsburg) open source hard- and software project which designs, build and operate fixed wing drones for search&rescue operations on the open sea. We mainly operate in the mediterranean sea in cooperation with other NGOs, who actually operate rescue ships to search for people in distress and rescue them before they drown. Currently we are ~8 people, and we are working in our free time on this project.

As we are a full stack project we search for a lot of volunteers and we basically need help in every domain:

* software: python, nodejs, vuejs, c++, ROS, imageprocessing/deeplearning boatdetection, postgres, ...

* hardware: pcb design, thermalcameras, rgbcameras, wireless connectivity (wifi, ELRS), microcontrollers, raspberrypi

* airplane design / mechanical design: construct planes for long endurance

* project management: very open for people to steer, control and plan with us

* airplane building: we need also people helping us build all the planes

If your interested: contact@searchwing.org

We can further discuss at psm.thrn@gmail.com

A companion project for uBlockOrigin that curates a corpus of content blocking templates, and provides the server to create you personal list of content blocking rules. The official instance just hit 800 active lists and a lot of template suggestions have been filed recently.

The easiest way to contribute is to create new templates, fix or extend existing ones. You need to learn the uBlockOrigin syntax and how to properly target the right elements, happy to mentor! See recent PRs for examples and https://github.com/letsblockit/letsblockit/blob/main/data/fi... for documentation.

The server itself is built with Go and HTMX, it's pretty low-maintenance, but there's interesting improvements if you want to toy with it (need to open issues for these).

ROS is the open source software powering robots all over the globe. The project needs volunteers in every capacity, from core robotics software to visualization, data logging, and developer resources. Gazebo is our sibling library used to simulate robots prior to deploying code. Many of our repositories have "Good First Issue" tags for new contributors.

Source code and community resources for ROS, like Discord and Discourse, are all listed here:

In the past I have been a Data Scientist for DHS and SAIC. I’m a pretty junior engineer(4 years experience) interested in Semantic Search and Evaluation. Currently taking an LLM class with a professor at Stanford.

I’m also interested in classic ML and visualization. I can help throughout the pipeline from creating/scraping a dataset, to transforming the data, to creating a front end that is practical for users.

You can reach out to me here or at ptdamiba@gmail.com

Thanks!

I don't think they are desperate for contributions but it's a welcoming environment and a fun project to hack on. You'll learn a lot just from reading the source and the incredibly informative PRs. The creator is a really talented developer with a great blog which shows up on the HN front page often.

One of the nice things about Datasette is that it's based around plugins, which I think are a really great way to contribute to an open source project - you get to build out new functionality without even needing to wait on pull requests from the maintainer.

TablaM is an in-progress programming language to provide a more ergonomic experience for building data-oriented applications.

This means that where most languages are focused on low-level details or engineering at large, TablaM is tailored with some small & big design decisions to make it enjoyable to write applications for e-commerce, finance, ERPs, and similar.

Cool things:

- TablaM marry the array + relational models. It means we should get very little need for manual loops and all the ops are vectorized.

- All the things are encoded as "tables", so you should be able to say the equivalent of `select * from file.open("a.txt") where line = "\n"`

- And then you could `join` `vecs & btrees & hashmap & files...`

- And then we have a standardized CRUD interface, so not `vec::push | btree::insert`

The code is in Rust. The major next stage is to add a parsing infra that allows to show nice errors like https://docs.rs/ariadne/latest/ariadne/index.html

I will spend this weekend adding issues and cleaning up dev documentation. I still need help with water shader, plugin version and migration handling, and a few other topics.

It's an almost real-time data streaming service for the polygon.io data provider.

It's a project that I started a couple of years ago during the pandemic. I've developed several data-sinks for this service (KDB, QuestDB, Postgres), but it's become more of a Theseus' Ship, development is never ending!

The aim is to build a backtester that will attach to this data service.

https://github.com/tranquilo12/goStreams

The README is outdated, but the gist of the project is that it's trying to be a service that can download all the historical data (for the requested tickers), and will stream the live data to a data-sink, without any issues, and with a good terminal ui.

I'm also thinking of integrating the Charm's libraries with this too, love a good TUI. (https://charm.sh/)

Anyone up for this? You can find my email in my profile.

I'm interested in building this out as a project, it will not be made into a company etc. The repo will be public.

Using LLM, Speach-to-Text and novel UIs to aid people with cerebral palsy, and allow them to communicate in real time.

Motūrus OS is a new operating system for VMs written in Rust. A lot of interesting things to do for someone interested in systems-level Rust projects, from a simple Elf loader to a crash-resistant filesystem.

Or just porting C stuff like vim.

A number of years ago I made https://waybackhn.com. It was a top HN post, and perhaps some of you remember it! https://news.ycombinator.com/item?id=9746188

As of recently I have not had the time/energy to maintain it, or to make improvements here and there (not that much needs to change for it to satisfy it's purpose). As you can see it's not currently working (although it was up to a couple weeks ago!).

It's a Python/Flask app. Hosting costs are $5/mo via PythonAnywhere.

Feel free to email me at waybackhn@gmail.com if you are interested.

OpenAdapt is the world's first open source AI-first process automation framework. If you're interested in the promise of Large Language Models (LLMs) and Large Multimodal Models (LMMs) / Visual Language Models (VLMs), but want to take them beyond question answering chatbots, here's your chance! We're using them to automate repetitive tasks in GUI workflows. See https://github.com/OpenAdaptAI/OpenAdapt for more. Python / TypeScript (but open to other languages).

https://github.com/sixarm/assertables-rust-crate

Assertables is a Rust crate that provides assert macros for strings, sets, streams, and more. This helps Rust coders write better clearer tests, and get better clearer error messages.

The aim is to encourage more developers to try Assertables. If you're a coder, want to write more macros? If you're a writer, want to improve the docs? If you're a testing advocate, want to reach out to developers to ask them to try Assertables?

The project is 100% free open source pro bono.

FreeChat is a simple LLM chat app built with SwiftUI and llama.cpp server. The main goal of FreeChat is to make open, local, private models accessible to more people.

In particular, would love help with adding a search bar, model browser, or making a satellite WebRTC-based iOS app (check the issues). Unicorn contributors who are comfortable with design and dev very welcome. Designers / design focused hackers, this is an open source consumer apps that prioritizes UX!

Interests are pretty wide ranging, from FOSS to electronic music to societal problems. Feel free to hit me up if you think you'd benefit from my assistance. Am in GMT+1.

Put "Volunteer Opportunity" in the subject, just so I don't confuse you with a recruiter.

Interested in any maths/geometry projects going around.

Currently doing a few bits with the gcc-rust project.

we are a small team associated with EleutherAI. looking to push the frontier of open source language models through self-play. so far we have implemented SPIN. compute included.

Piano Gym is a learning and practice ecosystem focused on prioritizing music theory and performance skills acquisition through the use of flash cards and sheet music. We use flash cards in order to pair them with modern learning techniques like spaced repetition, graded feedback, and progress tracking so that you can practice material and work through content that is managed by Piano Gym, and all you have to do is enroll in a school/course/lesson and do your reps! Just show up every day and do 15 minutes of reviews. You're going to make progress.

Our website uses the Piano to navigate exercises as well as regular keyboard/mouse input. We work on browser technology and are looking to eventually make it mobile devices.

We provide content creation for everyone so that anyone can make their own schools/courses/lessons and the best part is each school gets its own landing page.

For example we're using the methods book from https://freepianomethod.com which is provided by Mayron Cole, and if you wanted to practice it without signing up or enrolling you could easily visit this link: https://pianogym.com/schools/Mayron%20Cole%20Method

Even better when you find the piece you want to practice you can share it directly like so: https://pianogym.com/schools/Mayron%20Cole%20Method?sheet_mu...

Our goal is to do this for free. We believe that no one should be blocked from learning. And one of the issues with this at the moment is that our team is very small and has been currently working nights and weekends to make this happen. We would love the chance to add a technical member to our team in order to build this product out to its full vision.

Areas of work we need help with

- UI/UX

- Refining the piano playing game feel

- Adding support for external piano pitch detection

- Creating a community

If you're interested please feel free to direct message me or my email DoYourReps@gmail.com

I'm looking for people to help fill out the "standard library" for Oils/YSH. We're implementing a shell for Python and JavaScript programmers who avoid shell!

On the surface, this is writing some very simple functions in typed Python. But I've realized that the hardest parts are specifying, TESTING, and documenting what the functions do.

Fun part: you just write in typed Python and our tools automatically translate it to fast C++.

---

The most recent release announcement also asks for help - https://www.oilshell.org/blog/2024/01/release-0.19.0.html (long)

If you find all those details interesting (if maybe overwhelming), you might have a mind for language design, and could be a good person to help.

Surveying what Python and JavaScript do is very helpful, e.g. for the recent Str.replace() function, which is nontrivial (takes a regex or string, and replacement template or string)

But there are also very simple methods to get started, like Dict.values() and List.indexOf(), which can be less than 20 lines of code. Other people have already contributed code. Examples:

https://github.com/oilshell/oil/commit/58d847008427dba2e60fe...

https://github.com/oilshell/oil/commit/8f38ee36d01162593e935...

Again the specifying and testing is the real work.

This page can also be useful to tell if you'll have fun working on the project - https://github.com/oilshell/oil/wiki/Where-Contributors-Have...
