Loops is federated now
https://blog.joinloops.org/loops-joins-the-fediverse/

The app is still a bit rough around the edges but I think it'll improve as more people get involved. Anyone else wanna check it out? Maybe leftypol could host an instance.

context: Loops is like if TikTok was a mastodon. It took a while to actually be federated but they did it and there's a few instances so far.

It's nice but how much does it cost to serve videos to let's say 10000 concurrent users? Won't this just fall over if people actually use it at any scale?

>>31645
Idk, maybe instances could set size limits or compress it a lot. It'll be neat to see it get to the point of such a stress test.

Am considering getting a pinetab2 8gb for tutoring work.
The idea is to use a patched build of chromium for the mpp. [^1]
This should alleviate the CPU pressure from recording the small built in.
It should be able to run an unrecorded 1080p separate monitor for references too.
My concern is running the un-GPU-accelerated whiteboard.
Maybe krita could work, which has partial GPU-acceleration?
But this would seem to be a little less a convenient usage of the platform.
And I'm not sure if it would work anyway…
Anyone with experience on a RK3566 think it could handle it?

There's apparently not really negotiation on the encoding.
It's entirely possible that wyzant doesn't support the hardware encoding.

>>31596
>The idea is to use a patched build of chromium for the mpp. [^1]
Hardware accelerated encode is a (non-ARM) ChromeOS, Windows, or Mac OS exclusive.
Was looking into "brunch" as a way around this, maybe with crostini.
And meanwhile learned that ChromeOS is being replaced by Android…

The cleanest solution found was to use the ChromeOS kernel in Gentoo.
Use this Gentoo box to host LXC containers running the ChromeOS ROOT-A.

After all this it's possible that hardware acceleration still wouldn't work with the tutoring platform.
This is because of "negotiations" on the WebRTC encoding.
But probably it would work…

>So, i tried installing CachyOS today. Live CD looked like a standard "Arch for lazy and/or stupid people" kind of thing
I recommend EndeavourOS for that use-case. But I suggest that you just install Xubuntu or Linux Mint and use distrobox to get programs from the AUR (and other distros). Arch Linux requires that you read the wiki a lot and that you know the basics of terminal and bash. This is why I can't recommend Arch for newbies or lazy people.

>>31498
I installed cachyOS on a chinese handheld gaming computer (gpd win 4) and it's pretty good. the latest version of bazzite didnt even want to boot anymore. i didnt check if it had man or not, i just open the terminal to update once every week or so, cachyOS has been fairly unobtrusive despite it being a rolling release distro, which is good enough for something that is going to be showing steam in handheld mode like literally 99% of running time.

In my experience external HDDs have been horrible for reliability and constantly broke. But maybe that's because I was too clumsy and dropped them sometimes and didn't really know you shouldn't move them while they're plugged in

All my important files I have stored in triplicate on three old 3.5" hdd sata drives of different brands I had lying around. I figure if they are stored somewhere out of the elements at least one of them ought to still be readable 20 years from now.

You guys stressing out about pirated content you can download anywhere and you don't even give it the time of your day, meanwhile I lost all my teenage years' photos on my old phone that broke.

I got some WD Red HDD drives years ago and they're been at it just fine, I dunno why they have such a bad rep. You also should probably invest in some sort of NAS device with raid or whatever, 2 TB devices are dirt cheap these days and you can always use the peace of mind tbh

but it doesn't automate the office jobs though. because it gets shit wrong a lot. so in reality, at best it's used as a tool by a human being who has to double check all of it's work to make sure it's correct. and office work isn't like work on an assembly line where in theory there is an unlimited amount value you could produce were you not limited by your own body. in any given day there is a finite number of human to human communications tasks that have to be done by an office worker (and are the core of most of their jobs) which put a hard cap on the value they produce in a day and then they just play minesweeper or whatever and do their best to look busy

I've started making regular trips into the woods near my house, down a natural stream because it's the lowest part and creates a natural trail through what is essentially untouched forest and it's extremely nice to be out there and just center myself. There's deep water at some points so I've taken to just hiking in completely barefoot for about 2km.

It's become my new favorite hobby, you're not bored, you're not anxious, you're not worried about what people think, you're not in society, you don't have technology, any negative emotion evaporates about 1-2 hours in. The worst part of the entire thing is the walk back to my house. If it wasn't switching to winter I think I would just bring a tent out there and start living out there.

b-boobs

I think AI is making me dumber… I find I'm relying on it a lot for summaries of topics and thinking of alternate diversifying ideas because I can't think of something on the spot. It's getting worse. I can't think/reason/imagine for myself anymore because I ask a machine to do it for me. I think Socrates was exaggerating about the written word making people stupid and lazy, but AI really does have this effect. I think it maybe kind of has its uses, but I do feel dumber and not able to reason/hypothesise/imagine like I used to.

you know, i developed a strong sense of outrage at injustice from a young age because i was often randomly accused of things i did not do, both in and out of school, and the idea of having one of my papers marked as plagiarism just because i used a fancy word makes me angry just thinking about it.

What do you guys, gals and enbies think about Briar?
It's a p2p communication program but for once has a different approach.

From wiki:
>…communications with no centralized servers and minimal reliance on external infrastructure. Messages can be transmitted through Bluetooth, Wi-Fi, over the internet via Tor or removable storage, such as USB sticks.

Anyway, seems like a neat idea but maybe I'm missing something
1 post omitted.

Boomp

Whenever one of these decentralized peer-to-peer web3 projects comes up, the most important question to ask is "How does it do peer discovery?" because this is a pretty difficult problem to solve without a central server. I looked into it and apparently Briar just piggybacks on the Tor network and uses that for peer discovery, and Tor itself uses a set of directory servers for peer discovery, so it's not exactly fully decentralized. Also I'm not so sure about how the Tor people feel about projects like this; the network is already slow enough as it is without everyone and their brother using Tor as the backend for their Web3 projects especially when all their software is set up to run Tor in client mode by default and not relay mode, thereby using the Tor network's resources and giving nothing back.

Honestly, if all these web3 developers really want P2P they should learn how to do actual P2P, not cheat by using someone else's open-source volunteer-driven P2P network. That's script kiddie shit.

P2P is hard, peer discovery is hard, NAT traversal is hard. To design decentralized peer-to-peer networks requires a thorough knowledge of networking and computer science, doing a lot of research about the history of P2P and understanding how all the P2P networks have dealt with problems like peer discovery, learning about P2P network topology and unstructured vs structured P2P networks, reading the huge amount of academic papers on the subject and designing and running simulations of your network to conduct experiments and test different theories, etc.

There's a reason why the guys who developed Kazaa went on to develop Skype and become billionaires - they figured out how to solve some really difficult problems like NAT traversal and developing an efficient method of peer discovery using "supernodes" with the FastTrack/Kazaa protocol and then they applied those same principles to P2P audio/video communication when they wrote Skype. They actually did the work and built their networks from the ground up, they weren't skids piggybacking on someone else's network.

>>31630
I think exit nodes are rather the bottleneck of the network, but even then people are encouraged to route as much traffic as possible through tor and i always get decent speeds when browsing websites or streaming <360p video.
>>31636
What do you think about the DHT approach, which usually requires central servers for bootstrapping?

>>31637
>What do you think about the DHT approach, which usually requires central servers for bootstrapping?

Honestly I don't know that much about how cryptography or how DHTs work, I just know they are used by networks like Bittorrent and ED2K for peer discovery, but regardless of the methodology you always need an initial bootstrap node to access any P2P network, so full decentralization is not really possible with the unicast nature of the internet; it's not exactly feasible for clients to portscan the entire ipv4 address space every time they want to connect to the network, and scanning the entire ipv6 space would be impossible, so there has to be some point of initial contact with a trusted central authority.

they're making "AI GPUs" now. it's not a GPU at that point it's an AIPU. we don't call CPUs "central GPUs".

they should call them AIPUs and market them as that.

APU was unfortunately taken by AMD's marketing team pretending that an integrated GPU was novel or useful in a new way.

My money is on NPU.

GPU but the G stands for Gay

Machine learning specific processors have been around for a long while. Tensor processing units. Mostly good for regression, running cnns, rnns.

>>31631
yeah intel went really hard with their neural sticks, google had their tensor cores, apple had their own name for it too, mostly for computer vision, when AI was still cool in the eyes of consumers.

Do you think it's worth it to look for decent secondhand hardware as windows 10 is EOL?

I like my crusty ol' thinkpad, but I want something more modern (read: quieter and more powerful). Suggestions are welcome.

>suggestions
NixOS with niri window manager, with KDE window manager in case niri's sattelite-based window positioning borks something (i.e. Krita when using a tablet pen)
Basically install NixOS with KDE then add niri.
Niri is good for general use as it's lightweight.

>>31608
I meant hardware doofus

The EOL is not a sharp cliff.

1. You can still get updates for free with a Microsoft account.
2. Most businesses have already gotten rid of their pre-11 inventory. If you're looking for ebay deals this is where a lot of them come from.
3. A lot of people, especially sellers, install Windows 11 on incompatible hardware, even hardware that's too old to receive updates because the ISA is too outdated.

So you won't see the kind of glut in the market that you might think. That said you've been able to get a cheap T470 for years if that's what you want. It is probably cheaper than it would be if it was officially compatible with Windows 11.

>>31607
windows 10 iot ltsc is still an option. that or linux

I think windows 11 iot ltsc bypasses hardware requirements anyways so it doesnt matter

The newer thinkpads are alright, but no match for the old ones regarding price. Framework has some options if you're part of that sort of crowd.

i still daily an old t480.

Is a self-driving car really an invention that society needs? We already have a machine that was fundamentally designed for a human operator, there is no entity in the universe more well-suited to the task of driving an automobile than a human being, but now we want to try to retrofit every car with some software that replaces the human driver and will never be as good as a human driver and for what? Is driving really such a laborious and horrible ordeal for humans to endure, having to sit in a comfortable air-conditioned chair and listen to music for a while? Is it really worth wiping out an entire category of jobs that humans depend on to survive, just to replace them with software that is not nearly as well suited to the task and will likely kill people with no accountability?

>Is a self-driving car really an invention that society needs
Probably, because of points that have already been brought up. Personally I'm wary of them because if they become ubiquitous they might try to take away human-drivable cars. As someone who enjoys driving I'm not interested in that.

>massively gay
Like you? Anyways it doesn't matter be as gay as you want

Are self-driving buses gay

no. the personal motorized carriage, self driving or not, as a mode of transport and the subsequent design of infrastructure, industry and institutions around it have been a disaster for the human race.

Yes because it makes car ownership more expensive while nonetheless essential
>Self-driving tech is expensive! Cars need to cost more
>Insurance companies are unconvinced self-driving cars are safer! Insurance must cost more
>To improve self-driving systems, really the roads need to be redesigned to become "smart roads, tear them up! Gut public transportation projects to fund it
>The thing that is blocking the potential for self-driving cars is human driven cars, scrap them!
>Any one would tell you getting to the next town takes an hour, thanks to AI predicting there will be a traffic jam, you have been put on a route that will double that!
>You can't possibly service this vehicle, it's too advanced! Neither can your town mechanic, nope you're going to have to send it directly to Tesla I'm afraid
etc, etc

Generally speaking, consumer choice boils down to what brands you can buy, choice in how people use something is not ideal because naturally they will aim to use it for the least cost possible when the point of gaining market share is to lay claim to customers and more importantly their salaries.

I'm writing a tech demo of an idea I had about alternative GUI programming techniques. so far I had been using xcb and everything is going fine and the idea is working but I was thinking about adding wayland support before releasing the code. I know wayland has a compatibility layer with x11 but considering I'm not doing anything crazy, mostly just drawing rectangles and text, and handling events, I thought "how hard could it be to add native support with a few ifdefs here and there". however, it doesn't seem like there is much documentation on how to write applications for wayland, and most places just tell you to use gtk or kde or some other high-level framework

tl;dr my question is, is there something like this official xcb tutorial but for whatever the wayland equivalent of xcb is?
https://www.x.org/releases/X11R7.7-RC1/doc/libxcb/tutorial/index.html

Looks like maybe XDG-shell and libwayland-client. [^1][^2][^3]

:[^3] https://wayland-book.com/xdg-shell-basics/example-code.html

>>31601
huh, apparently it doesn't have drawing commands like x11, you just render client-side. I guess I will just use cairo then
but man it feels like a regression, as antiquated as it was, I liked that, in theory, you could use pure x11 programs through a network and the remote application would just send you the drawing commands to be rasterized locally

>>31602
It is pretty good, even locally if you're running a browser in a chroot or container like myself.

It's because wayland is garbage, put it in the bin.
