Comparing compression in AV1, x264, and x265 (kbin.social)

I recently got it into my head to compare the various popular video codecs in an effort to better understand how av1 works and looks compared to x264 and x265. I also had ideas of using a intel video card to compress a home video security setup, and what levels of compression I would need to get good results....

The “av1” numbers, which codec is that? There are many av1 encoders and even for Intel HW accel, there are at least two.

meaning every step of building the kernel, including the steps taken to build the C compiler toolchain, are produced by code that is simple enough to check for correctness and safety.

Full-source bootstrap isn’t about just the kernel, it affects every piece of software. With GUIX and Nix, every single package can be fully traced back to the bootstrap seed.

Though it should be noted that you do require a running Linux kernel on an x86 machine in order to bootstrap.

it is not quite to the point where it /just works/ on a lot of the computer hardware that I own.

Unless we get some serious money, effort and/or regulation w.r.t. OSS firmware, that will likely never be the case.
That has nothing to do with its technology though, that’s a political issue. GUIX is a GNU project and acts like proprietary software does not exist/is not a basic necessity in 2023.

the parts of Guix in which packages are defined are quite pure, even using monads for some things

Monads have nothing to do with purity. In fact, one of the most infamous usages of them is Haskell’s IO monad which is probably the most impure construct in the entire language.

it is really not too different from the Nix language.

Hm, I can’t help but think that a lisp dialect can never really be similar to any language except another lisp.

Atemu,
@Atemu@lemmy.ml avatar

Not quite: It’s an expression language.

The ultimate output of Nix is one set of data, usually the description of a derivation (~= package). You cannot cause arbitrary side-effects with it like writing to files or making network requests with it.

Dual Booting: How in god's name?!

I have one drive, 1tb with Pop_OS, and another, 500 on to which i want to install windows. (I know, I dont like it either but I want to play VR games via link cable cause ALVR is really mid) So, I put the ISO on a drive with ventoy, booted it up, got it all going. started to install windows on the empty drive. So, after the five...

Ah I think Windows does this “helpful” thing where it installs its bootloader into the ESP of any drive if it’s already present rather than the drive you explicitly told it to install onto.

You didn’t have anything in it yet, right? Unplug all other drives and then re-install Windows onto the drive. It should work as expected after that.

IIRC Pop!_OS sets the systemd-boot timeout super short; you have to hold a key after the firmware is done or something to get to it reliably or simply increase the timeout (1s is enough, I have it set to that on my systems). systemd-boot should give you the option to boot any windows installation though, it can auto-detect them.

Is this Seagate Exos drive too good to be true?

I found this its the cheapest 10TB Exos drive on Newegg and looking to buy 4 of them. I will be putting them in my NAS that I use for my media library and pc backups. The price I’m posting this is $130, I’m also looking similar Exos drives that are $250 is there a difference? Should I shell up for the more expensive drives?

You must be running an icredible HA software stack for uptime increases so far behind the decimal to matter.

NixOS beginner resources

Heya, been hearing about NixOS for a long time now, mostly from the peeps over at the Linux Unplugged podcast. So was thinking about jumping onto the nix-train, however it seems like it has a learning curve. Does anyone have any good learning resources, blog-posts, guides, whatever beans that you used to get started with NixOS?...

Atemu,
@Atemu@lemmy.ml avatar

The best way I know of is to get yourself a VM and get into the weeds; try to configure a system to your liking.

Follow the NixOS manual. The Wiki is unofficial; often opinionated, out of date or just plain wrong. Take it with a grain of salt. The canonical source of documentation is the NixOS manual and it’s not nearly as bad as you may have heard.

Make extensive use of search.nixos.org/options or man configuration.nix. Finding and making proper use of options and the module system is the bread and butter of using NixOS.

Eventhough everyone and their mom will recommend them to you for nebulous reasons, ignore flakes for now. You will know when you’ll benefit from using them; namely when you need to use something outside of NixOS/Nixpkgs. You’re going to have enough to figure out with plain old NixOS on its own though; I don’t have external dependencies in my config to this day.

To wrap it up, make sure to ask the community if something’s not working as expected: github.com/NixOS/nixpkgs#community

Note that while they’re disingenuously proclaiming themselves to be a “free” tool, the license is actually an unfree proprietary custom license.

Why is this not being developed inside Mesa? There’s even precedent for it; gallium9.

Atemu,
@Atemu@lemmy.ml avatar

Merging this into mesa would only bloat mesa while not really offering support for many applications at all.

But there already is a d3d9 driver inside mesa?

(Unless they have installed it onto their ASUS ROG Ally of course.)

There is no such thing as “directly” DX. The drivers of the major GPU vendors on Windows must also implement DX ontop of their internal abstractions over the hardware.

While Vulkan will theoretically always have more “overhead” compared to using the hardware directly in the best possible manner, the latter isn’t even close to being done anywhere as it’s not feasible.

Therefore, situations where a driver implemented atop of VK being faster than a “native” driver are absolutely possible, though not yet common. Other real-world scenarios include Mesa’s Zink atop of AMD’s Windows VK driver being much better than AMD’s “native” OpenGL driver, leading to a dev studio of an aircraft sim shipping it in a real game.

ifconfig.me. Can also be be curl’d.

Easier to remember is to just search for what is my ip in clear net DuckDuckGo (or Kagi if you have it).

they all ask for CAPTYA which is an obvious attempt to obtain ones true IP.

How exactly is a CAPTCHA supposed to discover your “true IP”?

Also note that your IP address is by far not the only thing used to fingerprint you. See abrahamjuliot.github.io/creepjs/ and browserleaks.com.

Use TOR browser if you want your starting conditions to be reasonably anonymous.

Even more critical for fingerprinting is user behaviour though.

Considering Gentoo

I have an old iMac that I am planning to install some flavor of Linux on and while I was looking at various distros it occurred to me that it might be a good exercise to install Gentoo on it. Other than a separate machine for documentation and downloading the necessary packages, what else should I have set up to try this? Has...

Atemu,
@Atemu@lemmy.ml avatar

I’d also add a build machine to the setup. Building a modern desktop system on such a machine would take days.

I mean, comments have languages and you can filter but the automatic detection isn’t very good.

The ability to mark communities as being a certain language by default (applying to all posts and comments unless specified or detected otherwise) would be great though.

NVIDIA getting its shit together maybe?

Given the recent pace of NVK development we probably won’t have to rely on that for much longer in 2024.
