The best method for extracting Blu-Ray source files is through VLC with libaacs installed. CTRL + D in VLC, select Blu-Ray and the mounted Blu-Ray drive, select "Convert" from the drop-down menu, select "Dump raw input" and the destination, then "Start".
Web rips are complicated and depend on the platform

To turn source files into something that most people can automatically run on their media players, you can use FFmpeg on the command line, or settle for its restricted GUI frontend, Handbrake
https://ffmpeg.org/ (https://ffmpeg.org/documentation.html)
https://handbrake.fr/
For a container, MKV and MP4 are obviously the standards
For a video codec, HEVC (x265) and AV1 (libaom/SVT-AV1/rav1e) are currently the most efficient at compression
For audio, opus is roughly 2x more efficient than mp3, with 64kbps being subjectively CD-quality in most cases. FLAC is a solid lossless format. Both formats support 5.1/7.1 channels although mapping them can be tricky and broken in FFmpeg
The trick is to find a compromise between file size (smaller bitrate) and quality. It's better to start off by encoding at the lowest possible bitrate and then moving up incrementally until you find the right one
Subtitles can be taken from the ripped source, done yourself, or imported from a website like Subscene
Extras from the source can be transcoded into their own files

They've already ruined news and articles since you can't search anything up without all of the top results being confidently incorrect AI-generated shit that doesn't even answer your question. What happens when they start generating videos or break down captcha so that even forums get run over?

Even before AI started worsening this issue this was bad enough I started learning to use my bookmarks and RSS feeds for sites I already know are reliable. Then just use forums like the one you're on right now to curate them to expand your library.
You never *needed* search engines, and you not missing out on something integral now that they aren't an option.
>What happens when they start generating videos
They already do, have you not used YouTube in the last 5 years? Curation and RSS fixes this.
>break down captcha so that even forums get run over?
Legitimate but manageable concern. use robots.txt and ip blocking to prevent search engines from scraping the site, create more obtuse forms of capcha, and foster in-site culture to make the tonal difference between bots and users more appearent, i.e. encouraging non-standard grammar and banning algorithmthings like wojaks.

AI can get around that by studying inputs from users and copying them. Say, people don't capitalize the first letter of words or use periods, ai can be configured for this. There really is no way to tell who is real and who isn't, if it's done properly.

Linux Desktop Environment: tde, also known as trinity desktop is something i used 2 years ago and its like a old fork of kde 3.5 from around 2005 or so that is still being maintained today. it was an interesting experience and every now and again i wanted to reinstall the de but i sometimes decide against it. so i decided to make a thread on it because i checked that nobody had mentioned anything about it here.

also i find it kind of cool that we are almost on kde 6 and this de is kde 3.5. it's almost like the halfway point

I know some people who have worked on an automatic mining jackhammer thing. basically when these trucks dump rocks to be crushed they must pass through a grate. rocks that are too big have to be broken down. previously this was done by hand. they were experimenting with machine vision to locate the rocks and figure out where to hammer them to break them. neat stuff

>The Metaverse, the once-buzzy technology that promised to allow users to hang out awkwardly in a disorientating video-game-like world, has died after being abandoned by the business world. It was three years old.
>The capital-M Metaverse, a descendant of the 1982 movie "Tron" and the 2003 video game "Second Life," was born in 2021 when Facebook founder Mark Zuckerberg changed the name of his trillion-dollar company to Meta. After a much-heralded debut, the Metaverse became the obsession of the tech world and a quick hack to win over Wall Street investors. The hype could not save the Metaverse, however, and a lack of coherent vision for the product ultimately led to its decline. Once the tech industry turned to a new, more promising trend — generative AI — the fate of the Metaverse was sealed.
>The Metaverse is now headed to the tech industry's graveyard of failed ideas. But the short life and ignominious death of the Metaverse offers a glaring indictment of the tech industry that birthed it.
Grand promise
>From the moment of its delivery, Zuckerberg claimed that the Metaverse would be the future of the internet. The glitzy, spurious promotional video [https://www.youtube.com/watch?v=VKPNJ8sOU_M] that accompanied Zuckerberg's name-change announcement described a future where we'd be able to interact seamlessly in virtual worlds: Users would "make eye contact" and "feel like you're right in the room together." The Metaverse offered people the chance to engage in an "immersive" experience, he claimed.
>These grandiose promises heaped sky-high expectations on the Metaverse. The media swooned over the newborn concept: The Verge published a nearly 5,000-word-long interview with Zuckerberg [http://theverge.com/22749919/mark-zuckerberg-facebook-meta-company-rebrand] immediately following the announcement — in Post too long.
