Noticed this on Fdroid recently, it has a really nice UI and auto generates real barcodes from images. Their document scanner app is pretty nice too. It seems like early development so I'm excited to see it improve from here!

Situation: You run a website and want users to have to do some amount of work in order to activate a function in your code. The "function" can be anything: creating an account, receiving some kind of in-game token/reward, dispensing coins from a faucet, whatever. Captchas are becoming increasingly both increasingly complex and increasingly useless against spam attacks. Various "proof of personhood" options are available (SMS verification etc) but come with downsides as well.

An obvious alternative to captchas is some kind of "proof work" scheme where the user has to run a certain number of hash calculations. This is cheap for individual users but expensive for spammers to spam, and could even net you a little crypto if you wanted it to. This, for example, is the approach used by Tor's anonymity network help prevent DDoS attacks. This is fine, but it serves no other purpose and uses lots of of energy. Though in Tor's implementation, it is only occasionally used as opposed to being used for every request.

My script is a "proof of useful work" captcha alternative. The user must download and process a chosen amount of workunits from a chosen BOINC project(s). This work is "useful" because it contributes to scientific research. BOINC is a software for distributed/volunteer computing and its used by scientists all over the world including the Large Hadron Collider (CERN) to offload expensive computation to the machines of volunteers. My script downloads stats from the BOINC projects and verifies the user has completed the work. If the user is a pre-existing BOINC user, they will already have sufficient credit to instantly activate the function on the site.

The default setup for this software is as a "crypto faucet", but you can plug-in any function you want: anti-spam, user registration, whatever. It calculates a cost for the "work" and makes sure it dispenses less than the cost, making sure no user has incentive to use the faucet more than a few times since it would cheaper for the user to just do the work on their own without the faucet acting as a middleman.

Downside of this tool is that the user may take some time to accumulate the credit (unless they are an existing BOINC user with credit) and the BOINC projects only report updated credit once every 24 hours (though if you ran your own BOINC project for this purpose, you could get this time down much lower). So while this can be good for longer-term tasks (such as giving an in-game reward to users who contribute to science), it is not quick. They also have to download and run BOINC (and change their username at a BOINC project), which is a big step compared to a captcha. In an ideal world, the BOINC work could be completed in the browser instead of by downloading BOINC, I believe folding at home had a client that could do this at one point.

Anyways, I think it's an interesting idea. Maybe you do too and can use it to your advantage somehow.

So this utility given a directory or path, will move randomly files in subdirectories and will move subdirectories randomly too. CAREFUL, if given system directory it will probably trash the system, equivalent of doing rm -rf /, except all the files are still there! :)

I don't know why I came up with this idea nor if its original but its mine.

You might ask, whats the use case, well that's an interesting question, you know why? Because... 🏃

(Of course, I'm open to feedback.)

Decentralized Encrypted P2P Chat (chat.positive-intentions.com)
submitted 2 days ago* (last edited 1 day ago) by positive_intentions@lemmy.ml to c/opensource@lemmy.ml



I'm excited to share with you an instant messaging application I've been working on that might interest you. This is a chat app designed to work within your browser, with a focus on browser-based security and decentralization.

What makes this app unique is that it doesn't rely on messaging servers to function. Instead, it works based on your browser's javascript capabilities, so even low-end devices should work.

Here are some features of the app:

  • Encrypted messaging: Your messages are encrypted, making them more secure.
  • File sharing: Easily share files using WebRTC technology and QR codes.
  • Voice and video calls: Connect with others through voice and video calls.
  • Shared virtual space: Explore a shared mixed-reality space.
  • Image board: Browse and share images in a scrollable format.

Your security is a top priority. Here's how the app keeps you safe:

  • Decentralized authentication: No central server is required for login, making it harder for anyone to gain unauthorized access.
  • Unique IDs: Your ID is cryptographically random, adding an extra layer of security.
  • End-to-end encryption: Your messages are encrypted from your device to the recipient's device, ensuring only you and the recipient can read them.
  • Local data storage: Your data is stored only on your device, not on any external servers.
  • Self-hostable: You have the option to host the app on your own server if you prefer.

The app is still in the early stages and I'm exploring what's possible with this technology. I'd love to hear your feedback on the idea and the current state of the app. If you have any feature requests or ideas, I'm all ears in the comments below!

Looking forward to hearing your thoughts!

ELI5: What is RISC-V? (sh.itjust.works)
submitted 2 days ago by sag@lemm.ee to c/opensource@lemmy.ml

So this very large company who shall remain nameless distributes a proprietary software development environment that includes a patched version of a certain, well-known open-source debugging tool.

The patch is to make said open-source tool support their products. It's not even hidden or anything: the binary is sitting right there in the installation directory, it's called the exact same thing the vanilla debugger is called and when I run it on the command line, it clearly says "patched for xyz".

The tool in question is distributed under the GPLv2 and I need to modify it for my own project. So I sent an email to the company to request the source code for their modification, but they refuse by playing dumb and pretending they don't understand the question. They keep telling me the source code to their IDE is not public. I keep telling them I don't want their IDE but the source for the modified GPL backend tool they bundle with it. But no: they claim it's part of their product and they won't release it.

Anybody knows the best course of action to deal with this? It's the first company I've dealt with that explicitly refuses to honor the GPL. I don't even think it's malice: I'm fairly sure the L2 support guy handling my ticket was told to deny my request by his clueless supervisor who didn't bother escalating it. But it's also a huge company that's known to be aggressive and litigious, whereas I'm just one guy and I'm not lawyering up over this. I have other hills to die on.

Who should I pass the potato to? The FSF?

Strava alternative? (sh.itjust.works)
submitted 6 days ago* (last edited 6 days ago) by LazerDickMcCheese@sh.itjust.works to c/opensource@lemmy.ml

I need to track cardio with terrain data, but I'd rather not trust Strava with my privacy. I know there are some alternatives, but which one is the most reliable and feature-rich? I don't have smart accessories, just and android phone. Preferably, I'd like an app that let's me track added weights for calorie purposes (like rucking).

Hi everyone,

as I don't need to do extensive video manipulation but simple cutting/compression of videos as well as extraction from every "nth" video frame to save as picture. I've been using avidemux and VirtualDub in the past for this purpose. However, both avidemux and VirtualDub are last updated in 2012/2023 and thus not up-to-date anymore. Thus, I am now looking for a linux-ready, FOSS, and up-to-date solution to do the same. Shotcut, Kdenlive and OpenShot are much too extensive in features for the simple things that I am looking for it to do. Does anyone here have good recommenations?

Thanks for your help! Temperche

In the inaugural episode of the OSS Climate Podcast, host Richard Littauer chats with our first guest, Koen Hufkens, the founder of BlueGreen Labs. They talk about the use of open source tools to address climate change issues, the role of community science, and the responsibility of open source maintainers towards their users. Koen also discusses the challenges of maintaining open source software, the impact of the European Union’s Cyber Resiliency Act on small-scale developers like him and highlights the importance of contributing to a solution for the current climate crisis.


I'm currently looking to develop an open source app that can help somebody. I'm currently out of ideas, so I'd like to heard if from you guys.

Sorry if it seems to lazy to ask for ideas like that, I just thought that I could do it since the result will be a free app.


I think this way of implementing and using AI is actually good from all perspectives (probably except some legal aspects but I don't think Mozilla will add a legally grey feature). What do you think about it?

And I'm sorry if it's already posted here. I didn't find any posts on this topic myself
