Jpeg Xtra Large fucking sucks you lying kikes. Completely unusable on like 80% of phones out there.
I'm not buying a $1,000 phone just to use this laggy shit. This is straight up a planned obsolescence scam.

It's libjpeg-turbo. I though about using mozjpeg/jpegli/jpeg-rs/etc BUT most of the images on the web will display JFIF in a hex editor meaning they're probably generated by a libjpeg-turbo encoder, if not worse (ie many pre-2000s JPGs can still be found today).

So I choose libjpeg-turbo as a good middleground.

Subjectively it looks like a stalemate to me. At similar AVIF filesizes JXL tries harder to retain underlying textures at the cost of blurring and it does work beyond 100% zoom in some parts.

I guess most metrics even if accurate weigh the average of an image. A better one if super autists had the audacity to work on would make some kind of heat map highlighting places where codec A did subjectively better and places where codec B did subjective better. Though SSIM is just too fast to give up right now especially if you're a web server going through thousands of images per second, IF they optimize image parameters for SSIM targets at all.

Objectively JXL is not 10% better than AVIF. Subjectively I think the JXL looks like dogshit now. Stock avifenc setting are terrible thoughbeit, I hope these things become the mandatory defaults soon:

Yeah, JXL blurring is really bad now. I'm sorry but Jpeg Xtra Large just plain fucking blows desu. Terrible decoding performance and no clear advantage over AVIF other than lossless but I doubt there's going to be a huge demand for 100 MP camera raws anytime soon.

I heard there's a new decoder being made for it, could that improve decoding speed of this shit thing?

I remember having to pay insurance for mine, which was like $15, I think. With that you could get a new one if you misplaced it or if you were retarded enough to break it. I went through 3 years of secondary with one, and mine was in immaculate condition by the end.

Back then I was unenlightened, but I wish I had known about corebooting them (assuming mine was compatible). I also could've just taken the msata ssd out of it to use for booting on my personal system.

I'm not sure what they do with them; they probably just recycle them. I wonder what you could do with a school year's worth of chromebooks in a cluster--probably run a small minecraft server.

Kinda embarrassing update: my wife picked up the robot and that somehow fucked up the LIDAR sensor and now it just runs into walls constantly. It's still under Amazon return window so we're sending it back and getting a new one. Apparently this is a really rare thing, none of our friends who have the same brand of vacuum cleaner had this issue and we can't really find anything online. I'm sure I could troubleshoot it or even talk to support but we specifically got it on Amazon during black Friday with the idea in mind of returning it if there were any issues so that's what we're going to do.

Not related to the /cyb/ privacy concerns discussion but since I was singing its praises I thought it would be disingenuous to not update the thread with this development

It's time to think of "protecting" yourself a little bit differently now that privacy is dead due to metadata and AI being really good at pattern matching.

OpenAI solved IMO using a plain LLM, unlike DeepMind, who used a custom system based on Lean 4.

Some myths that people are coping with (with answers):

* AIs saw these problems in their training data -- No, OpenAI got the problems within minutes of IMO ending
* AIs used a lot more time -- No, OpenAI's model had the same amount of time.
* They used a boutique system designed for solving IMO problems -- Only DeepMind. OpenAI used a general LLM.

AI is already smarter than you.

In b4: spelling gotchas and image-based tasks, or people who never used top of the line LLMs like gemini-3-pro and gpt-5-high.

The concept that a config could only be partaly invalid is new to you?
nginx comes with config checks as well and tells you exactly what is wrong, and if it can continue, it does so while giving you a warning.

Meanwhile cloudflares corporate Rust written billion USD nginx clone prints "panic" and dies.

And thats the intentional behaviour with idio(mat)tic written Rust.
Death is preferable.
Their definition of "Memory safety" specifically excludes memory leaks, because memory leaks "only" crash and kill the system. That is okay. Availability is not a concern. Crashing is fine.

In both C and Rust you decide how you handle errors. There is no implicit error handling.

Because you don't want partial or broken updates in large systems like this. You either succeed completely or rollback to the last working version.

it's on purpose, just buy professional-grade vacuums, they cost less and perform infinitely better while not looking gay as fuck.
I was on the market for a vacuum nearly a decade ago and noped the fuck out the vacuum alley when I saw the eurokistan pricing for these things who won't last more than the warranty period.
also dyson is pure garbage, shit quality for piss-poor performance, you're buying a stylish product, not a functional one, it's like the iphone of vacuums, you're not really suppose to be use it, it's so people who come to your house can see it.

>get it out, clean it and put it back, as simple as... hardware require maintenance, that's a fact of life.
And that cleaning requires more time than changing the bag, plus it's dusty as hell, so you either have to wear a mask or you're inhaling all the stuff you vaccuumed up to not inhale it in the first place. Plus, it makes a total mess, so you gotta vacuum the whole place again. That's not maintenance, that's masochism.
>a cheap karcher wd2+ is 50€ and will outperform and outlive EVERY SINGLE consumer-grade vacuum on the market. it's also very easy to repair and maintain if needed.
What class is it? Not sayin Kärcher is bad, but come on, a 50€ Kärcher is the definition of consumer-grade!
