I was asking. Human speech generally sounds fine even at low bitrates, but the 8kb/s mono pcm used by many bluetooth headsets sounds noticeably lofi.

 No.16944

>>16938
It's probably the bitrate and the specific bluetooth codecs/version more than anything that probably causes issues. The vast majority of people use mono microphones anyways. You usually get stereo mics on expensive devices, or if you're trying to do something like a professional recording.

 No.16945

Stereo audio is mainly to make it easier to distinguish particular sources when there are multiple. If you have a couple people talking or a person singing and playing a guitar for example, having two channels with slightly different positioning give dimensionality to the sound and your brain distinguishes them better.

i know ppl on this thread might have a poor opinion of social choice theory or ml, but deepmind came with a paper a few weeks about applying neural networks to mechanism design. it's lib bullshit from otherwise smart ppl but you be the judge

ABSTRACT:
Building artificial intelligence (AI) that aligns with human values is an unsolved problem. Here we developed a human-in-the-loop
research pipeline called Democratic AI, in which reinforcement learning is used to design a social mechanism that humans prefer by majority. A large group of humans played an online investment game that involved deciding whether to keep a monetary endowment or to share it with others for collective benefit. Shared revenue was returned to players under two different redistribution mechanisms, one designed by the AI and the other by humans. The AI discovered a mechanism that redressed initial wealth imbalance, sanctioned free riders and successfully won the majority vote. By optimizing for human preferences, Democratic AI offers a proof of concept for value-aligned policy innovation.

Result: Our AI system designed a mechanism for redistribution that was more popular than that implemented by human players. This is especially interesting because unlike our agent, human referees could integrate information over multiple timesteps to reward or sanction players on the basis of their past behaviour.

 No.16405

The solution in this paper can only work under socialism, you can't have an AI hand out money like that under capitalism. Is there a Marxist critique of mechanism design?

I'm looking for a new laptop since my ideapad 330 has a shit build quality and soldered ram. I don't need to upgrade just yet, but my keyboard is falling apart, the wifi card barely works, and this thing is kinda underpowered for a lot of tasks tbh. I want something with a better build quality, that i can use for a bit of gayman and video editing. I thought I could just get a thinkpad with an egpu but gpus are expensive as fuck and /g/ told me thinkpads are a reddit meme nowadays. Anybody got any ideas?

Was browsing an obscure infosec online store and they were selling a pack with two old phones, each preinstalled with firmwares and roms all about the security. These were extremely popular flagship phones from 5 years ago.

Whats the benefit of buying a package like that and where could I get the software without buying the package?

Kiwifarms encourages the use of TOR and VPNs
but if I go to kiwifarms.ru (net is blocked by cuckflare) the ddos Guard shows up. Of course the first thing that makes be a bit mad is the need of javascript but well it is what it is now no need to be mad at the moment but, i dont know why it just wont show me the captcha.

i went to the offical ddos guard site, which uses the same anti ddos service ofc, and the captcha appears. I enabled everything, javascript etc. standard browser settings on Tor/tails. still, on the actual kiwi farms it wont show it.

is it me, or kiwifarms?? i cannot currently use a vpn like mullvad because im using tails. and because I dont have money for it. Is there any solution, can i even do anything about it?

How did you change you IP in the first place? I assume your PC does not act as a router. Your PCs IP is only relevant to your router and other devices on the LAN. 4chan sees the IP (or NAT sth) of your router. Many routers dynamically assign their IPs, so restarting it could change the IP.

The problem with neural networks is they only brute force thus why human speed runners can still run circles around neural networks as humans can understand how to break a game while also knowing the that program flags need to be triggered else they can get in a unwinnable state, something much harder to do through brute force.

When planning an economy you have the same issue with humans actually able to make logical causal links rather then simply trying everything till you get a good result.

 No.16621

>>16611
I don't agree that neural networks force anything more than a human child forces things as it is growing and learning. There is certain element of chaos and uncertainty that a simple algorithm probably couldn't handle, but neural networks are better at working with chaos and with limited data than just list of "if this then that" type of simple algorithms that sometimes pass as an AI. I guess we can agree that at some level planning will need computers, programs at varied levels of complexity.

Could I make the argument that this is mostly a problem of insufficient datasets used for training and/or lack in the scale of neural network, since that is pretty much what separates a human (or animal) mind and a current neural network. Not that it probably needs nearly the levels of human complexity to provide results at human level or even better since it will be a specialized thing and when it makes a mistake it will be corrected and it will be improved. Unlike a human that might repeat the same mistake multiple times or at least multiple humans from generation to generation could repeat the same mistake multiple times.

What I however am a bit worried about is "black boxing" the whole planning process with neural networks and algorithms and such. I'm not afraid of any machine uprising, but it's dangerously undemocratic if nobody or only a select few can tell how and on what basis were these certain planning results reached.

I want to learn how to plan an economy so i can work in OGAS or CYBERSYN 2.0 as Cockshott's successore.
I also want to be able to be a 1337 H4X0R and program an AI version of myself so that if i die, the AI can continue unlocking files on a mysterious and broken, powerless computer which i fixed in my spare time so that my friends (who have been trapped inside of a school and forced to kill eachother to escape) can figure out who the mastermind is.

If you are an absolute novice with zero experience spend a couple of months learning Javascript , along with CSS and HTML . This will teach you the basics of programming .
Geeksforgeeks and W3Schools will be useful resources for this phase of your education.

Then move on and spend a year or two mastering C , C++ & C# to learn the principles of Object Oriented Programming . Refer to the books attached to this post for guidance.

During this time experiment with languages like Python & Rust to gain a deeper understanding of the underlying structures needed for programming.

"how to plan an economy"
I have several years of coursework in computer fields at a college level.
Lets separate this problem.
1. Programming Problems: You need a lot of things to run very fast which means C++.
2. Economic problems: If it was trivial, more would do it. Do you feel you know enough about money, resource allocation, and supply chains to describe this, and how they would interact with the world.
3. AI Problems: Even with several years of computer science, I can't tell you anything about Tensorflow.

Problems that need solving for the left that are easy:
1. Browse r/SelfHosted and self host some things not over the Internet for only people on your local WiFi.
2. Operate CNC and 3D Pritners with code that already exists.

What I think:
1. Is this a joke or fiction I don't understand
2. Are you trying to make simple code that runs on a tiny CPU that only manages 10 resources across 50 nodes or are you going for full hell trying to simulate a whole country?
3. People think about going into video game design because they love games. They find out games are hard and require teams of hundreds to make mediocre games. This is also the case with computer science. They start out thinking they will make something great. Either they make a self contained C++ code that does something small for themselves, they contribute to an open source project, they dish out the money from the people who know what they are doing, or they give up and only code if they get paid.
