HospitalRun is an offline first, Ember based, Hospital Information System for charitable hospitals in developing countries.

> What do you hope to build this month? We are focused on ongoing work toward reaching the 1.0. For a list of outstanding issues, see this GitHub milestone on the frontend app: https://github.com/hospitalrun/hospitalrun-frontend/mileston...

We're in need of folks with the following skills: Ember JS experience for general app development; internationalization and localization; New Relic instrumentation experience; automating deployments from GitHub; HL7 experience; product and UI design for lots of CSS and UI cleanup (https://github.com/hospitalRun/design); design systems experience for working on a styleguide and pattern library; docs writing for app documentation; web and marketing design for the hospitalrun.io site (http://github.com/hospitalRun/hospitalrun.github.io)

To contribute, check out our CONTRIBUTING.md file on GitHub (https://github.com/hospitalrun/hospitalrun-frontend/blob/mas...) and join our Slack team.

HospitalRun is open source under the GNU general public license.

Anyway, I joined your Slack channel.

Borg is a cross-platform (linux - osx - bsd) backup tool with deduplication, encryption and compression. It's written in Python (>95 %) with some Cython and C for low-level bit bashing.

> What do you hope to build this month?

We're working towards the release of 1.1.0 which may occur at the end of this month or the next. It includes a lot of features and general improvements already, but there's always something to do!

> What kind of skills do you need?

We can always use more testers and people writing better documentation. Code contributions are always welcome as well - test improvements, bug fixes, new features and so on.

There has been initial work on a native Windows version to the point that the basic features work, but it would really benefit from an active Windows developer. Windows issues: https://github.com/borgbackup/borg/issues?q=is%3Aopen+is%3Ai...

Open Synthesis is an open platform for CIA-style analysis of current events. Our mission is to help the public synthesize the flood of information from the media into actionable conclusions. Examples from https://www.opensynthesis.org/boards/:

- What is the relationship between WikiLeaks and Russian intelligence?

- What caused the Space X Falcon 9 explosion?

Now that we have a basic MVP, here's what we want to accomplish this month:

- Improve new user onboarding; reduce the learning curve of the main analysis interface

- Design and implement a moderation system; enable public sign-ups on the site

- Engage an initial set of journalists/analysts to get their feedback on requirements

- Surface information about evidence quality

- Create basic branding materials (e.g., logo)

In addition to these immediate goals, we're looking for designers to help with UI/UX design of the site, especially figuring out how to adapt the analysis tool for mobile.

Skills we need: design, UX, UI, internationalization, community design, community development, moderation, test engineering, Django, Python 3

For reference, the site currently supports the Analysis of Competing Hypotheses (ACH) technique [1]. ACH is a structured way of determining which explanation/hypothesis is most consistent with the available evidence.

[1] https://en.wikipedia.org/wiki/Analysis_of_competing_hypothes...

It will be interesting to see which techniques from intelligence analysis and business best lend themselves to collaborative analysis on the internet.

I think the potential here is very cool and may be interested in helping if I can.

But if I may ask: What's the future goal for this? More so, what do you mean by "actionable conclusions"?

(Like in finance the actionable conclusions were something along the lines of risk management/buy/sell/hedge it)

I'm all for better info and getting the true full story about events; but curious what actionable conclusion means here.

Happy to chat offline about it if more appropriate. Again, great work.

Project description: rsync for cloud storage

rclone aims to be an easy to use command line tool for transferring files to and from cloud storage systems. It currently support S3, Google Drive, Amazon Drive, Backblaze B2, Dropbox, Swift amongst others!

What do you hope to build this month?

Another month - another release - see the v1.34 milestone! I'd really like some help fixing some of the small bugs and features. The project is popular enough that it is using up all my hacking time and I'm not quite keeping up!

What kind of skills do you need?

  * Go (golang) is useful since rclone is written in it, though if you know C/C++ you'll pick up Go in no time at all.

  * An interest in cloud storage systems in general (or one in the list of supported systems) would be good.

rclone is MIT licensed.

Any help most appreciated no matter how small!

Thanks

A fast Code Editor for the web, similar to CodeMirror, Ace, Monaco.

Goal is to be as close to Sublime Text as possible in terms of features and performance. Most major work is done, like the text buffer which outperforms anything else, can handle big files and edits with very high performance. I'd like to improve speed further, specifically view optimizations, add more syntax highlighters, reduce technical debt, extract libraries onto their own repositories with more tests, add integration tests (only unit atm), inline documentation and more. There is a small guide to get started development.

Looking for someone passionate with frontend JavaScript development that knows their way around browser bottlenecks so we can work together and move this forward.

You may want to consider converting your "Issues" file into actual GitHub issues and creating a board to track them. That way people can comment on issues and things like that whereas tracking an "Issues" file is a bit more difficult.

Also you could use Markdown or AsciiDoc for the README. It doesn't look pretty right now.

Description:

SaferCPlusPlus is essentially a memory safe dialect of C++. Specifically, it is a library that provides, among other things, safe compatible substitutes for C++'s existing "unsafe" elements (i.e. native pointers and (unchecked) standard library elements). I believe it is currently the highest performing solution for making existing C/C++ code memory safe without requiring any redesigning or re-architecting of the existing code.

A motivating goal is to provide a practical solution for the reduction or elimination of "remote execution" vulnerabilities from much of the internet software infrastructure (web browsers, web servers, crypto libraries, etc.)

Q: What do you hope to build this month?

A1: Convert relevant benchmarks to SaferCPlusPlus to better quantify its performance cost.

A2: If someone's really ambitious, start work on automated conversion from C++ to SaferCPlusPlus.

Q: What kind of skills do you need?

A: C++

pdfparanoia - remove watermarks from papers (PDFs) - https://github.com/kanzure/pdfparanoia

Langauge: NodeJS

Brief: A minimal dependency injection framework for nodejs

Details: A nodejs dependency injection framework. Main advantage - (1) forces you to think in decoupled modular logic (also follow TDD practices), (2) better reusability of modules across years

Why does nodejs need dependency injection?

I think, for above 2 points. Writing DI modules allows better injection for unit testing in other languages; same hold true for nodejs - where better defined interfaces help out in unit testing.

It would be great to join hands with any independent contributors or small orgs; people who can evaluate if this approach holds a promise compared to other DI frameworks in nodejs.

Personal note: Its not easy to do it myself, because I don't have any financial plans with the particular project - it was mainly done to show my expertise and learn something new while doing it.

Usercorn - https://github.com/lunixbochs/usercorn

Skills: Go, C, Syscall ABI

Usercorn is a sort of debugging tool, kernel API emulator, and CPU emulator (powered by Unicorn Engine) rolled into one. It's hard to simply explain the vision but it can do things like run a MIPS Linux binary on x86_64 OS X (kinda like a more powerful qemu-user).

Plenty of GitHub issues here, but the main work needed right now:

Fixing up bugs related to glibc, dyld, and other runtimes. x86_64 Linux is the best supported loader right now, so the rest could use some love. There's progress being made on OS X / iOS + dyld startup right now.

Support for issuing signals to the guest CPU (need a signal handler table on a process's kernel structure, a syscall handler for `signal` and `sigaction`, and code that can jump the guest CPU into a signal handler and do a `sigreturn`)

More syscall emulation (~50/350 syscalls are implemented for Linux and OS X), but it's pretty easy to add new ones.

Support for guest threading and fork/clone (these will likely need a virtual process/thread table, then each thread/process can run on a Goroutine and take advantage of Go's existing scheduler).

Virtual filesystem layer, so syscalls like open/read/write don't go directly to the host OS and can be intercepted/overlaid in a more general sense.

lib43 - https://github.com/lunixbochs/lib43

Skills: C, ASM, Syscall ABI

Yet another libc, created as a result of this blog post: http://ryanhileman.info/posts/lib43 - mostly just has string, memory, number, and basic IO functions right now.

Ways to contribute: Pick a man page for any missing libc function and implement it in a simple/readable manner, or dive into an architecture syscall ABI (like ARM/NetBSD) and write the assembly backend for it.

glshim - https://github.com/lunixbochs/glshim

Skills: C, OpenGL

This provides desktop OpenGL ~1.5 sans shaders to any mobile device implementing OpenGL ES 1.0. It has been used to port dozens of open and closed-source games to the Pandora and other mobile platforms. It was also used for the Android real-Minecraft launcher (called Boardwalk I think).

Current goals include testing/improving the remote rendering (which allows software like emulators to easily serialize and remotely render OpenGL), increasing compatibility (testing games + filing/fixing issues on GitHub), adding WINE support (will be a trial/error process of running WINE, debugging/fixing the thing that prevents initialization, repeat), and writing more feature tests (which are actually pretty easy. You write a simple program to make OpenGL calls and assert which OpenGL ES calls should be emitted from the other end).

This project allows you to reproducibly patch compiled binaries with one or more short Python scripts. It includes an assembler (Keystone), disassembler (Capstone), basic linker, basic static recompilation/code transformation engine, control flow graph, and C compiler integrations... all in about 700 lines of Python. It was mostly created for use in attack-defense Capture The Flag competitions.

These are both working patches:

    def patch(pt): pt.patch(0x800400a, asm='mov eax, 1')
    def patch(pt): pt.patch(pt.entry, c='void f() { printf("hi\n"); }')

ActualVim - https://github.com/lunixbochs/actualvim

Skills: Python

This project is a massive hack to sneakily jam a Vim instance into a Sublime Text buffer. This gives you surprisingly good Vim keybinding support, and even works with your Vim plugins, but it totally breaks Sublime Text plugins and commands (as text changes won't be propagated back to Vim). As a result, the project is mostly a joke right now (just a pretty UI around Vim that breaks most interactive Vim plugins).

I do think NeoVim is mature enough to take this the rest of the way into being a serious project, and there's a fair bit of interest. The Sublime Text side of the interface works very well, so the main tasks here would be (1) swapping out Vim for NeoVim (which I seem to remember having a very simple remote control API), and a (2) handler to propagate text changes back from Sublime plugins into the NeoVim buffer.
