I saw this somewhen here on hackernews, but adapted it, so that it is an actually image, so the image/meme can be downloaded and hotlinked to.

This is basically what you learn in the huggingface smolagents course (months ago)...

They call it CodeAct

Build a little screen recording tool which apart from combined stream, also gives you the full resolution input streams (camera/screen recording)

Works only on chromium based browser as it directly writes into files on disk to not loose data. Sry

Shoutout to checkvist.com use them for years. Exactly enough bells and whistles.

It fits my brain of an endless deep list.

Have no affiliate with them apart from paying them each and every year.

"easiest/low tech" would be some sort of unix file-locking and inode. Only works if you are on the same host machine though...AAAND sounds like it would be quite hacky.
Which is a good thing :) I am all in for asking questions. If someone can't answer them, it usually means they have not thought about it and are either ignorant or will learn something themselves :D

(like me for your question, as I never tried TabSub with internet disconnected. Was delighted to see it works nevertheless)

Will check this tomorrow. If you come to it in the meantime, feel free to open a PR :) Thx

Works for offline apps as well :) (you would need to download the tabsub JS ofc and not use it from my server)

It means, that you don't need an internet connection for this to work :) (so it is no rabbitmq or so which runs on a server and the browser is just the client)

You can try on the demopage when you

1. play the songs each (for them to buffer a little audio snippet)

2. open the page in a second tab

3. Disconnect from the internt

Still works :D

Oh, did not know about it :D Thank you! Added a link to this to the TabSub landingpage

Thank you :) Simple because I don't know any better :'D

I am looking to build a list of German AI products. Because most companies I find are mostly consultancies.

Please help me create this list by adding your company or other AI product companies you know about.

Thank you so much!

Show HN: Remove personal identifiable data from a ChatGPT prompt

https://promptsecure.beansandbytes.de/

Most companies we are talking to (in Germany) have the problem that they don't want their employees to enter sensitive data into ChatGPT (or other LLMs).Mostly this is "ensured" through workshops and guidelines. But removing PII from a prompt is super annoying, especially when you copy-paste a lot of data back and forth.For this use case we did build PromptSecure. A webapp that automatically...

Damn, now with all the great replies, as it goes: Now I can't reproduce the problem anymore to measure with your different ideas
Measured the bandwith, nothing in the extraordinary. Roughly 10 Mbit/s peak. (With 250 Mbit/s fiber upstream and 5Ghz WiFi)
