Is this gonna be the replacement for both VP9 and H.265/HEVC?
Royalty free
Better quality and more efficient compression than both, however apparently slow as hell to encode
It can be multiplexed into .mkv, .webm and .mp4
It's currently being gradually, tentatively rolled out on pretty much every major streaming platform you can think of to replace VP9

I tried encoding a 10-second clip with this on my potato laptop, it lagged like hell while making the CPU fan go crazy

I like the implementation of grain synthesis in av1 as a method of preserving film grain at low bitrates which avoids the pitfalls of other methods such as oversharpening (psy RD in x264) and the inaccuracy of post-processing filters/noise generators. See picrel for an example screenshot taken from a file encoded at only 3 mpbs.


Encoding is definitely slow with AV1, I think it will work great once hardware encoders are common. I believe the h265 encoder is also slow (idk how it compares to av1), and h264 will still be a lot faster than both of them.

Google's Tensor SoC which they use in the Pixel 6 has special hardware acceleration specifically for their own special AV1 decoder
Not sure if it really matters when you can't reliably encode high quality and fast yet

this might be off topic but i've seen alot of older "freedom of speech anarchists" from 90s/00s suddenly turn out to be libertarians (if that makes any since). basically people back then who were into freedom of information and computer security are now crypto loving ancaps who want to own more shit then ever. there seems to be alot of them in the /cy/ scene. anyone else seen this?

Why is Linux so user-hostile? It feels like it was specifically designed by programmers so that they can feel superior to us common folks.

You at the normie that thinks only kids pirate.


>That's what the end user wants - a smug programmer telling them that the computer just werx for them.
not a programmer, i literally grew up on windows xp and 7 but i switched to linux because 10 was shit and 11 is supposedly even worse. i'm about as computer literate as every other zoomie
>just works
is not an expression of my smug elitism but rather an apt description for the linux user experience in 2022
>(it does not, in fact, work for them.)
it literally does. try any distro that markets itself towards normies, like ubuntu, mint, manjaro etc. literally all of them will run without issue, and will usually run faster than windows on most hardware. windows 10 somehow managed to take up 4.8gb of my ram idle, while endeavour os with xfce4 takes only 1gb, although i'm pretty sure it took 800mb by default. i don't know anyone who would rather buy an expensive updated version of a laptop than stick with the one they already own because the os isn't an unoptimized pile of shit
here's a list of the things most people need from a computer:
>web browser
>multimedia player
>office software
linux does all of these things well
it's not a more practical system just because of the monopoly and support for software that only professionals need

not what i'm getting at, but it's more fun to keep you out of the loop.

Look, you're going down the wrong avenue. We can sit here and litigate about whether it's better to learn scripting and fix some UI element because the guy who wrote the DE was a cunt and didn't just give you a menu option, or whether it's better to install a dodgy start menu replacement on Windows, but it doesn't count for much in the big picture.
The very fact that one has to switch to gnu/linux means it doesn't work for them. We can sit here and litigate the details of individual software choice all day, it's still not going to shift marketshares a single percentage point. Realistically, there are 3 options: You go full communist and smash Microsoft (my option), you try and make linux actually competitive in the market (arguably the Ubuntu option), or you can give up and admit that you're content with most people using Windows so long as you get to feel cool for using AmigaOS. Microsoft's dominance of the industry is a function of monopoly-capitalism, not a function of insufficient evangelism on the part of gnu/linux users. One would expect that this would come intuitively to anyone on /leftypol/, yet you'd half suspect that /tech/ was transplanted directly from /g/.

you might not mock people for their OS choices or sit feeling smugly superior to them, but others ITT clearly do. (because, as i'd never tire of pointing out, this kind of argument isn't really about the merits of computer systems, it's about ingroups and outgroups, friends and enemies, yada yada yada. not up to writing that part yet.)


>i countered that the network effect behind windows is so strong that it usually more-than-overcomes the disadvantage windows faces in being closed source when it comes to resolving practical problems
this looks dangerously close to turning an is into an ought
>If you want the end of proprietary software, what you need to do is wield the power of the state, the power of class rule, and restructure it all away
that is necessary but not sufficient. you also need agitation. I'm not seeing many CPC-funded free software projects for example, at least not in the English-speaking parts of the Internet. perhaps there are Mandarin-language projects that I have missed, but I'd at least expect more participation in the FOSS community than we see
>muh software veganism
stupidest argument I've heard so far today. vegans concern themselves with the feelings of objects


While you can say MacOS uses like their UI you can't say the same for Windows. The average Windows user was fine with Aero in 7 (if not they put in a customized desktop) then Microsoft shoehorned Metro (that nobody likes) into the desktop and server editions of Windows because Microsoft had a stupid plan to take on Android.
Linux is not harder for normies to use then Windows. The issue is normies can walk into Best Buy and pickup a computer with MacOS or Windows on it but not Linux. So far nobody is complaining about the SteamDeck running Arch so if normies could just get a Linux machine pre-built from the big manufactures they would put up with its oddities.

>can the new kindle be jailbroken?
There are a lot of kindle jailbreak instructions out there, so without knowing your exact model and firmware version, i would say: probably yes.


I would also say if your kindle is not currently jailbreakable, it's a good idea to just put it on airplane mode all the time and wait to see if a new jailbreak comes out. I did this after missing a jailbreak and my kindle updating itself to a newer version, and now I can jailbreak since there's a new one out and it hasn't updated since.

In uBlock Origin, if you enable "I am an advanced user" in the dashboard settings, you get dynamic filtering which is basically what uMatrix does (they were both developed by the same person before he merged uMatrix's features into uBlock Origin and stopped developing the former)



This only applies to scripts though. Blocking iframes in umatrix lets you open them separately and I often disable images, media and css when I'm on a slow network link.


Depends, if I want to mess with advertisers I use Adnauseam and Trackmenot, if I have a need for speed I use ublock origin.

>Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers write once, run anywhere (WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. As of 2019, Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers.

<Oracle offers its own HotSpot Java Virtual Machine, however the official reference implementation is the OpenJDK JVM which is free open-source software and used by most developers and is the default JVM for almost all Linux distributions.

Java has all the features of any OOP lang with functional additions as well, multiple libraries for every conceivable use case, is an A-tier general purpose language, runs fairly quickly (as fast or half as fast as C/C++ in most cases), tons of people know it or learn it in university, or in their corporate jobs. Other languages like Kotlin, Scala, and Clojure, as well as Ruby/Python implementations, and many more are built on the rock solid engineering of the JVM.

Most of silicon valley and top corporations use Java to some extent as well. It has a solid open source implementation (OpenJDK) which is the standard. It's easy to learn, simple enough for midwit programmers to collaborate and make maintainable, portable, performant software that fulfills a practical purpose or need. It's the workhorse of programming languages.

Why then does Java get so much hate in the FLOSS community? Do people just hate OOP? Is it because of Oracle's nasty reputation? Is it because of the old school, GOF-design patternified J2EE apps thats used to be made (and are still maintained)? Most modern java can be written with minimal XML (esp. with modern spring boot).

Or is it simply because JavPost too long. Click here to view the full text.

It's hilarious how people who claim to be software "engineers" will disregard all evidence proving how fast and efficient Java is and will keep claiming that it is a resource hog just because they had bad experiences with Eclipse.


God, python and ruby have their use, but I really dislike command line programs that you can feel run slow. I remember playing around with vagrant and homebrew, and it's such a joke that running –version feels so slow.


>Tons of linux distros (RHEL + clones, Ubuntu, Suse/opensuse) are owned by corpos and those make up the majority of distros anyway
This is one of the causes behind the adoption of systemd and other freedesktop sponsored abominations. Notice RH is also involved in Java development.
But there is no reason to focus on the particular corporations, because this is only a symptom of the huge amount of labor required to maintain OpenJDK.

>Redefining TRU(tm) open source as made by hobbyists and not foundations is wrong

You wouldn't want to live of the scraps Microsoft publishes on their Github. These corpos publish their code because some people fix their bugs for free. They retain authority over their project and no personal or community-driven effort would have any hope of forking their codebases, that consist of decades of cruft. You may observe the Palemoon fork of Firefox, to see how code complexity or simply inane standards can consign open-source software to the realm of large organizations with many developers at hand. In the case of Oracle this is unanimously bad.

The licensing incident is a good example of how Oracle still tries to preserve their ownership of Java.
IIRC the memory access pattern of the Oracle JVM makes it perform particularly slow on ARM (relevant papers are paywalled), hence the Dalvik VM uses registers instead of a stack-based architecture.


I still have bad experiences with IntelliJ indexing and the like and having to tune GC just for editing. Java is fast, if you tune it right and let it warm up, but it still has to start the JVM and warm up.


alot of the slowness of java is really just spring being shit and overuse of reflection. Other nu-java ee frameworks like microprofile, micronaut and quarkus are supposed to be better.

This thread is for discussing the future of imageboard software, with particular relevance to large imageboards such as leftypol.

Vichan, one of the most popular imageboard softwares and the parent of (the parent of) leftypol's, has recently had its founder Hotwheels say "STOP USING VICHAN YOU FUCKING NERDS", after a major exploit in the embed function dating back to 2011 was found.
( https://nitter.net/fr_brennan/status/1570456345244991496#m )
He insists "Please STRONGLY CONSIDER deprecating vichan on your instances as I have repeatedly begged users to do."

However, despite its struggle to find developers, it has the most developers and most consistsntly active developers out of the imageboard softwares I am aware of (that said, I don't know much about the futaba forks)

The other non-fork competitors seem to be lynxchan (I've seen a board using it call it an abortion) and jschan. Pretty sure both are run/maintained by approximately 1 person at any one time. Furthermore, despite some cool nifty features including websockets instead of polling, they're in many places well behind vichan in terms of expected functionality. I personally believe that a migration within the next few years to one of these would be tolerable but horrible, and that if their approximately 1 maintainer vanishes, the project will stagnate like the others.

So what is the future, on the software side, for leftypol? Is the best path forward to edge back closer and closer to vichan by pushing our differences upstream, and ride it out until it has no more maintainers?

This topic has been beaten to death several times on /tech/ alone, let alone other parts of the internet/chaniverse. I'll leave this copypasta here which basically explains the whole thing.


Vichan: the software that just won’t die

Why vichan hasn’t been replaced and probably never will

Vichan and Vichan derivatives such as lainchan have long been the standard of imageboards in the “alt chan” universe. Briefly, Lynxchan looked poised to take over as the imageboard standard, but it’s reliance on mongodb left it vulnerable to data corruption and unreliability issues.

Any semi-competant coder can create an imageboard with 80%+ feature parity with vichan within a few weeks or even days. So why, after all this time, has no imageboard managed to take over from vichan?

Wordpress is blogging software written in PHP, from the dark ages when PHP was a terribly designed language. Like vichan, wordpress is a structureless, poorly written, outdated, spaghettified oldphp-based piece of shit. Yet, it persists. There are countless plugins, themes, and tutorials created for it, which enable countless nontechnical small business owners to create good looking websites with prebuilt themes. The very ease of use corresponds with it being hell to maintain and write plugins for. Ironically this self-induced difficulty has created a whole ecosystem of plugin and theme developers, selling overbloated plugins that perform functionality that could really be done in a few lines of code, mindlessly installed by nontechnical bloggers. Even conservatively, around 30%+ of all websites use wordpress, including major corporations like airlines, banks, and media conglomerates. The fact is, there is a self fufilling prophecy, where a software’s popularity can meme itself into existence. Wordpress is the Kim Kardashian of cms software: popular for being popular, despite an utter lack of any other redeeming qualities. And vichan is essentially the wordpress of imageboard software.

Post too long. Click here to view the full text.


just to follow up, I've been straight up TOLD by the people who run leftypol that even if I wrote a replacement chan today, they wouldn't switch to it.

Unless you have some alternative userbase which is willing to adopt brand new software, there's no point.


The technical aspect and the sociological "userbase" aspect are completely independent of each other. Most "normal" people don't give a shit about features, all they know is that you can post and that's it.


Did they say why they wouldn't change?


basically they're focused on improving leftypol's VIchan variant and its functionality and rewriting it would be too much work, plus they wanted to do it in scala if it were done at all.
