ouraf··on New insights into neural end-of-life
Would it be possible to preemptively inject any substance that neutralized these effects directly in the neocortex in patients to give one last chance of treating them before cerebral death or the damage of the initial rupture of neurons is already too great to allow a person to make a recovery?
ouraf··on Welcome to the ad-free internet
Ublock is more convenient and i don't need to pay one subscription per site.

In the past, it was about selling convenience. Netflix, for example has beaten conventional torrent sites because it had almost all movies you'd ever want in a single place, steady connection and a good UX. Now there are a dozen different services to juggle, each with a constantly changing library and torrents became more convenient again.

ouraf··on A new old kind of R&D lab
open a space to spitball ideas for future models. You never know when a stray idea might spark a revolution. After all, not too long ago, "Attention was all we needed"
ouraf··on How many lines of C it takes to execute a + b in Python
Is there any comprehensive comparison and benchmark of intepreted languages or languages with a REPL and analysis of how each interpreter handles common operations?
ouraf··on 23andMe confirms hackers stole ancestry data on 6.9M users
I know this is a terrible event and we should look at this critically, but i can't help but read this headline as the start of a sci-fi conspiracy theory/spy fiction novel.

"It all started when that hacker group obtained the genomic data of millions of humans..."

ouraf··on Ousted propaganda scholar accuses Harvard of bowing to Meta
The problem is that the way the "propaganda scholar" wrote her whistleblower piece kinda like an appeal to emotion.

This can go either way, specially since the team and the project still exists, just without her.

ouraf··on Claude 2.1
"[...]If I write well-formed C, it compiles, not protests in distaste. If I write a note, the app doesn't disable typing because my opinion sucks[...]"

There's a rust compiler joke/rant somewhere to be added here for comical effect

ouraf··on Krita AI Diffusion
A tool is a tool. If the krita team is anti AI, they can choose to just ignore a plug-in or extension made by an independent team.

Do your thing.

ouraf··on Humane AI Pin
It doesn't need to compete with smartphones IMO.

The best use case i can see for a device like this a hands free recording and support for law enforcement, rescue and emergency teams.

Imagine a paramedic recording all the info about the victim of a car accident and being able to project relevant information or questions on the asphalt or any other surface at night. The rescue crew would have both hands free to stabilize the victim, maybe even get the victim's medical history without having to stop everything to type on a smartphone or tablet.

ouraf··on Cursorless is alien magic from the future
That kinda looks (sounds?) like some star trek science team member programming stuff: just talk to the mainframe and check the output
ouraf··on Simulating History with Multimodal AI: An Update
I have my concerns about using it for historical recreation, but for fantasy worlds, that's actually a great tool

You could make a very big, very rough world based on a define set of core ideas and then deliver it to real authors to make it a cohesive and fun background for a new book or movie series, for examples.

Like giving a big marble piece in the rough shape of a human so that real human sculptors can make a suitable statue out of it.

ouraf··on Reality Labs has lost $11.4B during 2023 (there's still one quarter left)
That's kind of by design, though. One of the mandates of modern corporates is "generate value for the shareholders at all costs". This frequently means betting on and pushing risky ventures to be the first or, even better, the second to set foot on a whole new market.

Many gaming streaming projects fell before Microsoft and Nvidia cracked the code, and MS is using it to pull people to their ecosystem. Sony lost a lot of money over the years flailing around with GaiKai until they had a stable streaming offer. Even Google lost much of their investment in Stadia.

Similar stories goes with AR games, live streaming, targeted ad services, etc. Some companies have to burn cash and take losses to map all the pitfalls and opportunities of the new market.

The whole metaverse thing is poorly define and kinda useless, but executives firmly believe that when you get all the high income families hooked up with eyes and ears covered by technology, you'll be able to advertise and sell products and they won't be able to look away without turning off their entire platform, and most people don't make this sacrifice. They're more than willing to burn a lot of cash and kill many jobs for the small chance of breaking through and reaching that magical market with the excessive ammount of disposable income of the top Apple fans and engagement levels not even tiktok or the most predatory gacha games could reach.

ouraf··on A Dutch graphic artist reconstructed Tenochtitlan in 3D
Have you considered 3d printing this? It would be a massive project, but would be a museum level display piece.
ouraf··on Extreme parkour with legged robots
one part i didn't fully get is if, after the training, the machine can calculate and implemente the same maneuvers while "offline" (not connected with any other device to assist with the navigation) and what would be the computing hardware requirements for smooth navigation without external help or update? (for example, guiding it with a joystick or GPS waypoint on rugged terrain and having it automatically adjust to each unforeseen obstacle in the way)
ouraf··on John Carmack and Rich Sutton partner to accelerate development of AGI
I thought Carmack was focused on VR. He changed gears after leaving Meta, it seems
ouraf··on KSP2 is spamming the Windows Registry until the game stops working
Makes sense. one of the simplest ways of saving data in Unity (but not the most correct) is saving values via PlayerPrefs[0]. In Windows, this saving method defaults to registry instead of creating a separate save file in the game folder. if you don't make your own system for storing variables or running everything in cache and then use a smarter way of saving data, it can get out of hand fast.

This was way more common in the old Unity 5 days, though

ouraf··on The Cutting Room Floor
Gold mine of a wiki.

Check the pages for really big and famous RPGs when you have the time (Fallout 1&2, Baldur's Gate 1&2, Final Fantasy 7, etc.) Some games have so much stuff cut at the last moment you could pratically make a whole new game with it

ouraf··on Unity plan pricing and packaging updates
redo the math for an indie with Unity Personal and a sudden hit with 250k sales

    Units Sold:   250000
    Gross Sales:  $1 247 500

    Steam Fees:
    $0-10M (30%): $374 250

    Unity Fees (personal or plus):
    250 000    :  $50 000

    Net Sales:   823 250
Now it's more or less 6%, and that's before development costs and taxes.

It's a big bite for something that's impossible to code out of the project.

Imagine if Oracle charged a dollar every time someone ran your software the first time on the JRE in that machine. installation on a new machine? pay again. Old customer reinstalls the JRE? pay again. main executable or JRE update? pay again.

Not so funny anymore.

ouraf··on RyujinX – Open Source Nintendo Switch Emulator
" i dont know how anyone gets paid to do this and yet there is so much incredible depth to learn that is probably undocumented because of legal issues"

- There IS a path to commercial emulator development. Most of these "retro collections" you see being sold on video game online shops are a frontend, a custom made emulator to avoid any legal/license issue (Avoiding GPL code as much as possible), a cool frontend and some extras depending on how much the team could unearth and license from the original developer/publisher/rights owner. Hell, Nintendo and Sony had teams making official emulators for the Playstation 1 emulation on PSP/PSVita/PS3 or almost every nintendo console before the GameCube for Virtual Console games

- Each country has its own set of laws, but using US cases as an example, developing an emulator for research purposes only (or at lease not competing directly with whatever you're emulating) and not using any file or code snippet from the original hardware can get a pass.

That's how some emulators go by without getting a Cease and Desist from Nintendo or Sony. And that's why they never bundle the BIOS with the emulator, even if it needs it to emulate... well... Basic Input and Output Systems.

Deterrence.

First offense could be excused as "blazing a trail and burning down the forest by accident".

But now they have a direct business contract with bigger companies that can lawyer up way better than open source foundations that live on donations and goodwill of code contributors.

Imagine they make a huge deal with Sony or Dell and either company can prove their "secure" enterprise plan was used for corporate espionage.

The legal and reputation repercussion could sink even a fortune 100 company

ouraf··on ChatGPT Enterprise
Doesn't that make OpenAI cannibalize part of Azure's AI market share?
ouraf··on A place where no humans will tread for 100k years
Seems to be the least of all evils for the problem: Nuclear waste is nearly impossible to recycle in a cost effective way, can't be burned, can't be decontaminated effectively and won't decompose easily.

It need to be stored in a clearly marked and delimited place, to avoid accidents, until someone in the future finds a more definitive/cost effective solution, or until it wears off, even if it take a long time for our standards.

ouraf··on Most companies do not need Snowflake or Databricks
That's common practice with mid sized companies and above, though:

- find something that can probably give some competitive advantage or please shareholders - Identify it as "not part of our core business" - Pay a third party company to do it even if it would be cheaper to things in house. If something goes wrong and the shareholders ask questions, the CEO can blame them instead of their own IT department and reassure them they're "focusing on what generates most value for the company".

ouraf··on Jazz² Resurrection: Open-source Jazz Jackrabbit 2 reimplementation
The dev is using nCine as the engine to leverage its porting capabilities (it even has a Nintendo Switch homebre version). nCine itself can use SDL2, QT5 and GLFW as backends

Interesting decision.

Loved the memes on the essays page. It has motivated me into checking the project more thoroughly
ouraf··on Ts_zip: Text Compression Using Large Language Models
Right now it's more of an idea to keep on the back of your head than anything else.

LLMs are still being created and refined, token dictionaries are also changing. For this to work, you'd need something future proof, to avoid having and ultra efficiently compressed file that can never be opened because part of the decompressor is an extremely big and outdated data file that may or may not disappear from the most acessible sites for being heavy and obsolete.

That being said, if we ever make an "absolute" language model with a "definitive" dictionary or make a cheap and efficient way of grounding future models to make them "backwards compatible", this coould be used to preserve data for longevity. HDs and SSDs don't have the same durability of books, floppy discs can demagnetize, etc.

I think microsoft was working on a "true long term" storage medium using a crystal engraving technique to ensure the data could live for thousands of years and survive the elements. For that extreme case it might be useful.

ouraf··on My $0->$100M->$0 in 5 years story
Tangential question: how hard it is to "buy back" the company shares from venture capital firms?

I've heard these "grow until you burst" stories some times, but no one ever told a good way of getting free from the VC without retaliation

ouraf··on CNET is deleting old articles to try to improve its Google Search ranking
Don't kick the messenger. It's already good that someone (allegedly) from a department related to the situation could give some input. No need to dump all your frustrations on them

ouraf··on Open-sourcing AudioCraft: Generative AI for audio
It will be a licensing nightmare, just like Llama1 was.

But clever devs can study it to make better software and pressure them for a better license on the next release. Worked for LLaMA 2
