Why isn't there a open source book format?

Adobe and Kindle have a monopoly on their property formats, (mobi, azw3, pdf)

Who made .eupb, it has DRM protection so I assume it isn't open source

This article shows a plethora of holes in Linux, problems which even Windows has methods to curb. It seems like the current model for linux kernel development somehow is failing (either in lacking funding, or something else). What will it take for Linux to catch up to corporate alternatives?


> M1 Macs also use Pointer Authentication Codes (PAC) to ensure forward and backward-edge protection.
You might want to include this for that part: https://www.kernel.org/doc/html/latest/arm64/pointer-authentication.html


Nice arguments
Too bad I didn't read them


it's not "arguments", it's exposition of data /g/tard
If you use linux, it's worth taking a look at. I use qubes, i'm not anti-linux or anything. Knowledge is power comrade


"exposition of data" have some balls you STEMlord




Id like to talk about how trustable is TOR actually?

> The code is open

Not everybody can read it, many checkers are not trustable and the CIA even admitted that it kills by using Metadata.

The Authority nodes are centralized, in universitys and maintained by ex government people from the CIA for example.
I also once read a study by a university on who funds the TOR project, tldr, over 80-90% the US government, mainly the department of defence.

So a system developed by the US government, the developers being mainly from them, it being mainly funded by them, the CIA killing based on metadata, it is fair to ask the question if we can even trust TOR.

So, since US agents use tor to communicate with their government they need us people to actively use TOR so they are more hidden, and of course they, if they could see everything on tor, would not arrest everyone who does illegal shit because they dont care about stuff thats not a threat to their money and deepstate. And there have been some moments where big bugs have been arrested by authorities by the FBI where we are still asking ourselves, AFAIK, how they knew of this bug/way of finding people over TOR. So how much else do they know in case they actually need to make someone vanish? The people behind TOR are definetly not trustable, but they hold the most power.

so what do you guys think about this?

Tor has a problem with decentralization, there are about 2.5 million users on Tor but only about 9000 relays and bridges.

I2P on the other hand has about 60000 - 74000 routers, most of them routing traffic.

It's way easier to compromise the Tor network than I2P, despite I2P having a significant smaller user base… or am I missing something?


Mostly trustable. As long as you keep your protection on Safest, you should be fine. I wouldn't be surprised if the gov. contributes to Tor because agents use it.


Imagine throwing a fit about the fact BBC and Facebook thought someone out there might find their .onion services useful, and that the Tor Project had the audacity to not make their entire marketing campaign specifically target *you*

I understand the premise of supercomputers. I was not disagreeing with that.

I specifically am referring to user policy over 1500 computers with 100 managers.


The year of Linux will arrive if China starts producing PC components with architectures they have full controll over to a wide consumer market and Microsoft in a desperate attempt to reduce the market share of products which have supply chains that the Americans can't interfere with and lack built-in backdoors for the NSA somehow "bans" those Chinese processors or other components by making it impossible to use with Windows. This would drastically increase the global market share of Linux. You might say that it would make no sense for Microsoft to undermine their number one asset, that is monopoly over the OS market, but we have seen the United States do the same thing on a larger scale with the freezing of Russian assets which undermines their general financial dominance or the trade war against China which will on the long-term force the Chinese economy to detach from the chokepoints in the global electronics supply chain that the US is using to blackmail them. If in the scenario I've described earlier Microsoft rejects the nuclear option, then this would surely mean that the American Empire has accepted its inevitable decline and is only a few steps away from its final collapse.


Maybe the first step will be a Chinese console. Like a Tencent console or something.


We already have the Steam Deck that is a Linux console. What would really disrupt the market is Linux office machine that undercuts OEM Wintel machines to the point the likes of Dell and Lenovo goes bankrupt like Atari and Commodore did, leaving US companies with no choice to buy Chinese PCs for their offices if they don't want to assemble themselves.


Seems like kinda an irrelevant question these days, no? Most consumer level computing is done on phones these days, and we all remember just how well Microsoft did in that battle. And while they do hold a grip over business, education and government, it seems like they're fully making a pivot towards software as a service rather than hard windows installs. I could see Linux and Google potentially eating their educational market share in the future, but I think the dominance of Azure, Outlook, Office (especially Excel with the many arcane scripts some businesses rely on) and Active Directory in the business sector has them firmly in trenched, especially for larger, older organizations. And in the case of the US government, their lobbying has successful made many Microsoft owned software a basic requirement to meet DoD standards. I don't think its impossible for Window's market share to diminish if Linux becomes more competitive, the problem is the other "mission critical" Microsoft software that helps keep the platform relevant. And even if suitable alternatives arrive, it would take decades to fully migrate, not to mention they could have proprietary anti-user components as well.

Free DNS is a dynamic DNS domain sharing project that offers free subdomains that can be registered and administered by members

List of domains available to register a subdomain from: http://freedns.afraid.org/domain/registry/

You can volunteer any domain that you own to the project, too
You can set it so that you can give your approval to a subdomain before letting it be registered (private) or waive the right to approve (public)

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)
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


I failed to mention older formats like VHS and Laserdisc with releases that never made it onto DVD or Blu-ray
More knowledgeable anons can drop info on those


> For audio, opus is roughly 2x more efficient than mp3
Why is it not more widespread?


SoundCloud switched to it in 2016, and I think it’s used by other big streaming platforms more and more lately
Some rippers are experimenting with it (search for it in qBittorrent’s search engine)


>In late 2014 and 2015, Google's video platform YouTube started offering Opus audio along with VP9 video in the WebM file format, through DASH streaming.
>Since 2016, WhatsApp has been using Opus as its audio file format.
>Signal switched from Speex to Opus audio codec for better audio quality in the beginning of 2017.
>In 2018, SoundCloud switched from MP3 to Opus, reducing half of its required bandwidth for music streaming.

The workers who moderate internet have always been underpaid and over traumatized, I even speak from experience, they have to see gruesome shit daily, even the mods of this site could relate

Apparently the ones that work for tiktok that work through a france based company in Colombia are thinking of unionizing
I was watching a tech show about it, and it's true when you think about it, how in the future we'll how crazy it was to put so many people through PTSD

If these people went on a strike, the internet would be 1000% worse, In a good and sad way though, It seems A.I will replace them

Do you have any thoughts on this job sector in tech that goes unnoticed mostly

The government gatekeeps CSAM detection algorithms. It is actually not easy to gain access to these detection services, despite being provided free of charge by major providers like Google, Microsoft, Cloudflare, Amazon, etc.

Let me rephrase,
The US government is actively making it extremely hard for people to fight CSAM dissemination online, by unnecessarily gatekeeping free (as in gratis) services offered by companies.

I've thought about making a FOSS service that collects CSAM hashes, to circumvent this issue, but the government obviously has way way way more data, as well as decades collecting it. It would take years of many contributors to build a useful database. Idk, I think about it from time to time.


if it was just normal for all forums and chans to hash all pictures, and have a system for flagging the hashes of pictures that are removed as CP, i'm sure a good database would build up.

they literally explain it right there - one based on detecting children, on based on detecting nudity. If child, and if nude, then bad


Part of the problem is mod/janny powers give people a rush and there's a draw to being able to control a community, or to suck up to whoever is in charge. Mod/janny organizing or struggle is obstructed by the inherent character of the work and the personalities/ideologies that attracts.

vichan does md5 hashes (through the optional .json API) and lynxchan uses I'm guessing SHA256 for filenames. That said, easily evaded with single pixel changes or by some who overlay a link in the image.
phashes could be effective.

I made a prototype system for collective antispam, never got put into active use but technically it could, with a bit of refactoring and improvement.
https://xj9k.neocities.org/ (code not included, but it's nothing advanced. can share if someone gives a fuck)
Fair warning: there are no images and links are broken on purpose, but most of them are CP link spam.

It worked by downloading the catalogs/overboards of vichan and lynxchan boards, looking for duplicate threads that are on multiple sites, generating a vichan filter to block it, and then uploading it onto that site. Just ran on a shitty pi so it's simple.
Of course there are false positives but it gives an insight into commercial spam and evangelical schizos.

I actually got mail from some kiddo whining about free speech because of this lol


>The government gatekeeps CSAM detection algorithms.
makes sense since they're the only ones legally allowed to posess it therefore they are the only ones who can engineer an accurate filter
