cosarara··on Show HN: How I Topped the HuggingFace Open LLM Leaderboard on Two Gaming GPUs
My first idea would be to generate one of those heatmaps using RYS as the base model. And see if it gets meaningfully better. And then again!
cosarara··on KDE Plasma 6.8 Will Go Wayland-Exclusive in Dropping X11 Session Support
You can use IgnorePkg in pacman.conf. Things might break, but the feature exists.
cosarara··on I regret building this $3000 Pi AI cluster
> Compared to the $8,000 Framework Cluster I benchmarked last month, this cluster is about 4 times faster:

Slower. 4 times slower.

cosarara··on Sometimes Software Is Done, or Why Hugo Why (2024)
But we are not talking about a malicious ssg, we are talking about a vulnerable ssg that somehow needs to be patched. Unless your ssg connects to the internet, this is a non issue.
cosarara··on The Internet Archive is back online
That doesnt help with CGNAT.
cosarara··on Modder re-creates Game Boy Advance games using the audio from crash sounds
> I can't imagine how it would be possible to construct a jump call with an invalid value

You can use the bx instruction to jump to any address stored in a register.

> Additionally, what would happen if one of TheZZAZZGlitch's incorrectly reconstructed ROMs was run on a real GameBoy?

It would crash, and eventually start playing the ROM on the speaker, the whole point of the video :)

cosarara··on Raspberry Pi is manufacturing 70K Raspberry Pi 5s per week
We were comparing the N100s not to the Pi5 but to this $98 Wo-We AMD: https://www.wo-we.com/collections/mini-pc/products/mini-pc-a...

The grandparent comment said you could get an N100 for the same price, but they are all more expensive no matter how you look at it.

cosarara··on Raspberry Pi is manufacturing 70K Raspberry Pi 5s per week
For x1.5 the price, from what I can see. Are there any under $100?
cosarara··on Portal 64 – A demake of Portal for the Nintendo 64
The typical modern gaming PC uses a lot more power than the original xbox. Yes maybe it's more efficient because it's doing "more", but in the end it's one person playing a game.
cosarara··on My First Impressions of Nix
Depending on what you are patching, it will invalidate a great part of the cache, and you will be looking at very long build times for everything in your system.
cosarara··on User In Yer Face, a worst-practise UI experiment (2018)
I gave up scrolling the terms and conditions.
cosarara··on Children aged 2-6 successfully trained to acquire absolute pitch (2012)
But not every synesthetic person sees the same colors for every key, right?
cosarara··on Show HN: JXL.js – JPEG XL Decoder in JavaScript Using WebAssembly in Web Worker
The rationale would be that it might be more efficient to WASM-decode JXL than to download a JPEG, especially in pages with lots of images, but I would want a fallback if the browser does not support WASM.
cosarara··on Show HN: JXL.js – JPEG XL Decoder in JavaScript Using WebAssembly in Web Worker
https://cosarara.me/misc/jxljs/ in my test, it will simply fall back to jpeg, even if the jxl.js library is loaded (scroll down to Image with fallback).
cosarara··on Show HN: JXL.js – JPEG XL Decoder in JavaScript Using WebAssembly in Web Worker
Is it possible to fall back to a jpeg if the browser does not support js, wasm, or web workers? With a <picture> element, maybe?

I did some tests on my own server and found that for some reason it's quite fast when running on https, but super slow on insecure http. Not sure why that is, maybe the browser disallows something that's important here for insecure connections.

cosarara··on We're moving away from swap partitions on our Linux servers
And I think that, sadly, it's not even a full solution, because linux can manage to get thrashing even without swap. It pages in and out things like memory mapped files or the content of executables of stopped processes. See for instance: https://serverfault.com/questions/898388/how-to-prevent-kern...
cosarara··on A 14kb page can load much faster than a 15kb page
Maybe, or maybe the new equipment is much more efficient than the one it's replacing. It sounds true, but you can't really tell if it is or not, and really my annoyance is in saying it costs any estimated amount of energy, or carbon, to transfer 1GB of data. It does not, the transfer itself is basically cost-less. What costs money is running the infrastructure that makes it possible, and that's much harder to measure.
cosarara··on A 14kb page can load much faster than a 15kb page
I agree with this. I was disagreeing with the statement

> Bandwidth is extremely carbon intensive.

and the reasoning that supports that statement.

cosarara··on A 14kb page can load much faster than a 15kb page
I don't agree with the reasoning presented. It takes the estimate for the amount of energy that it takes to run the internet infrastructure and clients (141GW * 8765h in a year = 1235865 GWh), divides it by the amount of data transferred yearly (241 billion GB) and gets to 5.12kWh/GB.

You might argue that if people download more data, more equipment needs to run to enable it, but really all this energy consumption is happening regardless of my PC being idle or saturating its fiber pipes with torrents. If your website weights 14kb, all this same equipment needs to be on for my PC to load it.

cosarara··on Photos of chickens, taken by chickens
By that logic, I am taking a selfie every time I speed in front of a speed camera, or I drive in front of an average speed zone camera.
cosarara··on Humans being confounded by color photography
A red filter will cut out blue skylight further, but a yellow one gets you halfway there. It's hard to nail exposure across filters (since each cuts out a different amount of light), but here is an example:

[1] with no filter: https://cosarara.me/images/hn/01_no_filter.jpg

[2] with a red filter: https://cosarara.me/images/hn/02_red_filter.jpg

[3] with a yellow filter: https://cosarara.me/images/hn/03_yellow_filter.jpg

These are not real film, it's a digital camera in BW mode using real coloured filters in front of the lens. Unfortunately, no clouds today, but the white wall can serve as a replacement.

cosarara··on TikTok shares your data more than any other app and it’s unclear where it goes
> It’s a bit ignorant for you

A bit rude but ok

> TikTok can harvest data on the type of content posted and what users interact with

That's exactly what I said, and I think this is expected by the users and does not worry me.

cosarara··on TikTok shares your data more than any other app and it’s unclear where it goes
What kind of data? TikTok knows what content I interact to... on tiktok. That's it. Unless they have an android 0-day or something. It has no access to my mic, camera, browsing history, contacts list, or anything useful. Guess who has access to all that, if they want it, though? Google and Facebook (through whatsapp). What is the privacy concern here, exactly?
cosarara··on Ambiguous PNG Packer: Craft PNG files that appear different in Apple software
It sounds like this would be a nightmare in Unix filenames; even if everything in my system is perfectly clean utf-8, I could be trying to open "café.txt" and get a No such file or directory error because the input has é encoded a different way from what is saved on disk. You would need to list the directory contents, decode everything, perform the comparison in Unicode code points, and pray there is no more than one match. Any web UI that deals with files would have this kind of issues.
cosarara··on Fat Fritz is not the Only Ripoff and now ChessBase is Getting Sued
They are talking about ChessBase the product. Ugly and expensive but the best in class.

OP is about other prosducts by ChessBase the company.

cosarara··on Please fix the AWS free tier before somebody gets hurt
> I have a handful of AWS Lambda functions with a DynamoDB backend serving hundreds of clients, my bill for the month of April was $0.01.

What kind of thing do they serve? Somewhere I could read more about this kind of project?

cosarara··on Gnome 40
> we just need one person who cares about this feature

Uh no. There have been at least 3 separate attempts at implementing this. One of them actually lives as a fork on github, and it works. None of them have been merged. The gtk devs don't care.

If your electricity is free, it's all profit after you pay for the hardware.
cosarara··on I asked GPT-3 for the question to “42”
> With growing excitement, I typed the prologue into the console: > Why is there something rather than nothing? How is it possible for Universe the exist?

It bothers me that the second sentence in the prompt has a mistake in it: "for Universe the exist" instead of "for the Universe to exist".
