Trouble uploading pdfs to Tabula

Yesterday I used a great tool for extracting tables from pdfs. https://tabula.technology/

It worked well for my first 3 files, but now the files I'm trying to upload just hang on "waiting to be processed..."

Any ideas how to address this? The first time I tried these files, I accidentally disconnected from my hot spot before anything uploaded. I'd like to try clearing the cache, but can't seem to find it.

I also tried renaming the files


Any help is very much appreciated!

ConfMap – Visualize & Explore Your YAML/JSON Configs (Now with Multi-View & PNG Export 🚀)

Hey folks 👋,

I’ve been working on ConfMap, an open-source tool that turns your complex YAML/JSON configuration files into interactive mind maps.

💡 Why? Because configs like Kubernetes, Docker Compose, and Helm often get too messy to reason about.

✨ What’s new:

🔍 Search across large configs instantly
🗺️ Multiple visualization views to explore hierarchy the way you like
📸 Export to PNG for documentation or team sharing
⚡ Runs in the browser → data never leaves your machine

Built with the vision of making configuration files not just readable, but queryable and AI-ready (via ConfQL).

Would love your feedback, contributions, or ideas for features!

EzAntiAntiCheat

EzAntiAntiCheat

Hi everyone,

I’m working on EzAntiAntiCheat, an open-source project designed for research and experimentation with kernel-level anti-cheat systems. Its purpose is to provide a safe framework for studying and managing situations where aggressive anti-cheat software interferes with each other, such as conflicts between Riot Vanguard and other anti-cheat platforms.

The project is fully open-source on GitHub: https://github.com/PalorderSoftWorksOfficial/EzAntiAntiCheat

I’m looking for contributors interested in: • Kernel driver development • System-level security research • Safe experimentation with software conflicts and aggressive protection mechanisms • Documentation, testing, and tooling improvements

Notes: • This project is intended purely for research and educational purposes. • It is not designed to bypass or disable anti-cheat systems for gameplay. • Improper use may render software unusable; please use responsibly.

Contributions, feedback, and collaboration are very welcome! If this post violates community rules please contact me instead of instantly banning me from the subreddit so i can fix the post from the issue! Extra Note: EzAntiAntiCheat completely wipes the anti cheat driver and if its gone the game might reinstall or crash as an fail safe
Edit: i forgot to add an license too the github repository making it NOT open source

Alternatives Looking for Open Source SharePoint Alternative with Advanced Metadata and Versioning

I’m setting up document management for a hobby/startup group and I’m hoping to find an open source solution that goes beyond basic file storage. Specifically, we need something that can handle structured metadata from day one, not just folders and ad-hoc tags, but the ability to classify and manage files with rich, enforced metadata.

Core Requirements

• Version history – proper file versioning, not just overwrite
• File sharing / secure access – either built-in sharing or SSO integration
• Advanced metadata classification – enforced options from predefined lists (similar to SharePoint’s managed term store)
• Custom fields – ability to define unlimited metadata fields at either a group or system level
• Flexible views – toggle between simple file listings and rich metadata views
• Smart folders – ideally both flat and folder-based views would be supported

What I’ve Tested So Far

• OwnCloud / OCIS / Nextcloud / OpenCloud – Great for file sharing, but metadata is too limited (just basic tags, no enforcement)
• Papra – Promising new platform, but tagging system still too simple
• OpenKM (Community Edition) – Looks good, but lags behind commercial release by \~3 years and lacks key features
• Paperless NGX / Papermerge / Docspell – Nice for document processing, but no proper versioning (can’t upload revisions under same filename) and no file sharing
• Teedy – Lightweight and easy to set up, but doesn’t cover all of the requirements above
• Seafile – “Smart properties” feature looks perfect, but licensing beyond 3 users makes it un-viable for a small team

We’d really like to avoid being locked into SharePoint early, but we also want the structure in place so we don’t have to migrate later. Any suggestions, experiences, or even partial solutions would be hugely appreciated!

How do you satisfy the GPLv3 in an electron app?

Hi, I'm very interested in publishing my app I've been working on for some time. I'm aware I can publish the source code as GPL - however because it is an electron app, I can't publish the binary unless I offer all source code that contributed to it.

So... is it saying I have to hunt down the source code of electron and all other dependencies I use, then hunt down the source code of all of electron's dependencies, then hunt down the source code of all their dependencies.... And keep all of this available to anyone who downloads my app? It sounds like I'm going to have to preserve multiple gigabytes of source for a <100 MB bundle that's actually <10MB my code... all for what's literally just a webpage? 😬 I feel like it'd be easier to just zip up a web browser with my code and it'd be easier to keep my code free...

Or am I reading this wrong and the GPL need to procure source code doesn't spread down into your dependencies, only up into people who depend on you??

There is an additional problem that I can't guarantee that the code of the dependencies could ever actually become the "object code" of my program since I used the npm hosted versions and I definitely just use the electron that webpack gets for me - but I doubt that's even worth getting into at this point, lol.

Really, all I want is to make sure that whenever my code (incl modified versions of it) does work for anyone, they can actually see the logic that went into the result. I want anybody who runs my code to be able to know it's not scamming them!!

Google Home alternative?

Hello everyone, I'm looking for an alternative to Google Home, where I can control my various smart devices in one app. I know that Home Assistant exists, but you need to self host the server, and I can't leave my computer on 24/7. Does anyone know any FOSS app that let's me control my smart devices without having to host my own server?

Making an AI based os/kernel system

Im trying to find people to help in a project the concept is simple an open source os/kernel that use ai as it's center to translate everything including applications into usable apps on the os no more need for thousands of os like linux, android, windows, mac, ios etc... simply using that os as an unification system It need to be easy to install on anything be it a smartphone, computer, mac, etc... as the main os the ai at the center of the os should be allowed to incorporate api and other ai systems automatically into its reasoning and updating itself on security concerns and reasoning automatically it would also work as a node systems with offline capabilities where once a security risk is detected it transmit automatically to other users the fix which is then applied or not depending on user wants akin to any update systems The ai would be the translator, the security, etc... it would basically be the os and the kernel It will also be able to be used beyond devices like computers and into full robotic usage too you want to install it on a vr headset the ai detect the hardware download the needed translating layers adapt the api and core used etc... the os would be able to run everywhere a fridge, a roomba, a smartphone, everything and as open source

You can also directly query the ai at the center of the os using a chatbot system that also adapt depending on the hardware and based on your demand the os could modify itself based on your needs

For the name of the os I don't want it to be pretentious, complicated or weird and i certainly dont want it to look like it belong to someone so I want to keep it as "OS" or "AI OS"

In short I'm trying to find help to make the ultimate self learning os/kernel system using ai as it's center in open source format

I realize the implication of such a project yes it will take years, yes the kernel level will need to be hybrid at first and yes it's basically building skynet, etc... no need for condescending comment thank you for reading

Need feedback on my own search engine!

Hi everyone!

I've been trying to build a search engine, for people to use as an alternative to already open source search engines like SearX, or as an alternative for privacy conscious ones like DDG or Startpage, and I need your reviews and feedback to improve it! :)

I'm trying to be focused on bringing the open source benefits of SearX, and modern UI's and features like DDG-like search engines. We have AI summaries for search queries, beautiful widgets for Wikipedia, in-search Video and News recommendations and a few more services that I believe you guys will love!

It has been a few months since I've started, feedback and suggestions were mostly from some local communities interested in this topic, and I want to make it a bit more recognized in the internet.

Feel free to criticize! You can reply to this post or use the feedback button at the right corner of the search tab. Thank you!
