PixelOfDeath··on Inverting a binary tree using x64 assembly

PixelOfDeath··on Minecraft Running on Asahi Linux with Open Source GPU Drivers
It's the other way around. GLES Versions become a subset of later OpenGL Versions.
PixelOfDeath··on We need a replacement for TCP in the datacenter [pdf]
I see UDP more like a low level interface allowing you to build your own on top. Where you decide what packages need to be revived 100% and which one can be dropped. Basically the foundation of your very own TCP with hookers and blackjack.
PixelOfDeath··on Measuring CPU core-to-core latency
Core1 would send a invalidation to get exclusive (write) access to that cache line. This would be routed to Core2. Which removes the cache line from its cache.

If core2 now accesses that cache line again, it would not find it in its L1, or L2, and at L3 there is the cacheline directory routing the request to core1.

PixelOfDeath··on Unreal Rust
Get real, we can no longer protect you from the fact that unreal engine only runs in long mode!
PixelOfDeath··on Intel enters a new era of chiplets
Genuine Intel incompatible items detected in room. Rectify environment and drink verification can to re-enable subscriptions to:

Cores+™ - experience the performance of multiple cores

GHz+™ - awesome speed for the latest games and office spreadsheets

Memory GiB+™ - make room for multiple applications

Note that monthly subscriptions to this Intel Premium Experiences™ will continue regardless of whether re-verification is successfully carried out.

PixelOfDeath··on A C++17 thread pool for high-performance scientific computing
It's also about prefetchability of the next task.

If all cores e.g. do an atomic add on a single counter variable to get their next task-id just in time, then there is no chance for the cores to do any reasonable prefetching. Because most of the time another core will come in and write to this variable that all prefetching is based on. With short tasks, you can end up with a full pipeline stall each time a new task is started.

PixelOfDeath··on Germany is offering a summer of cheap trains
"We are sorry to inform you, but a big multi billion dollar company has selected a snipped of your video/music/name and registered it within our copyright/trademark system. Therefor we will automatically delete all of your content and sue you for one hundred million dollars in damages on their behalf!"

Dang sounds like a copyright/trademark troll to me! Really disappointed that they allow something like that here.

Edit: I only know graham crackers?! But I guess that's not it?

PixelOfDeath··on Why is it hard to buy things that work well?
Well we also ended up with BTRFS raid5/6
PixelOfDeath··on BP quits Russia in up to $25B hit after Ukraine invasion
Yes! Nobody can just claim such terrible acts from a state that openly murders political opponents and currently is carrying out an invasion of a peaceful country.
PixelOfDeath··on Perl code that is syntactically correct only on Fridays
Aliens landed on this planet, found out about the date format MM/DD/YYYY, and left in a hurry. They are currently preparing a gamma ray burst out of pure compassion and pity but also a hint of disgust!
PixelOfDeath··on Thank You, Valve
And just consider how much money flows for "micro" transactions. There is plenty of "players" willing to pay money for hardware cheats.

My observation is that competitive online gaming is over. It's just a cesspool of cheaters now.

If you exclude like every user land library there is (including the glibc)

PixelOfDeath··on Italian Courts Find Open Source Software Terms Enforceable
This multi licensing is rare compared to all the GPL-only (or comparable open source license) projects.

I's basically a big fuck you to anyone who does not commercializes his software but wants to contribute to the software ecosystem and only expects users to also contribute back to it.

Maybe we need a GPL4 with a building nuke. "You agree to pay 1 Trillion dollars if you do not publish your changes".

PixelOfDeath··on $45k in AWS charges due to account being hacked to mine cryptocurrency
I'm very sorry Ms. or Mrs. msh.

But the 3.4 trillion dollars have to be paid back by Monday! And take better care of your information next time. It is the duty of every customer to check cash dispenser for skimmers before using them! This is clearly written out in out general terms and conditions!

They are x86 APUs with a very powerful GPU and high memory bandwidth. Something you can not buy on the open market to use it as a PC so far.
PixelOfDeath··on Amazon will allow many employees to work remotely indefinitely
Maybe the are used to collect all the suffering by sitting over the main office with all its cubicles.

Maybe they are afraid of a way more aggressive competition for workers and what they have to pay them. Considering they now could switch the workplace via different login credentials.

PixelOfDeath··on Firefox: Dark pattern consent dialog invites users to share their location
I use waterfox because I already hat enough of the firefox bullshit. But even there you now have to enable the search bar. And pressing tabulator when inside the address bar does no longer jump to the search bar but directly into the browser windows.

Dark patterns shit all over this. "Oh sure you can reenable the search bar, but go suck a dick if you used tabulator for switching to it"

PixelOfDeath··on Berlin buys thousands of apartments from corporate landlords
This is a standard corruption pattern in Germany. Sell state infrastructure for Cents and buy it back for Euros.

Take for example our Federal Printing Office (Bundesdruckerei).

PixelOfDeath··on YouTube takes down the Ig Nobel show because of a 1914 recording
I remember somebody who always claims his own videos with a secondary account. So if nobody else claims it, he still gets the money. And otherwise nobody does.

Well except youtube keeps it in all this cases. Sad sad google now has to keep all the money for them self in a system they designed. What a unlucky coincident. Nothing they could do against that.

PixelOfDeath··on Swap on HDD: Does placement matter?
> But simpy put; on modern disks the logical block address has no relation to the position of the head on the platter.

WD kind of tried that with device managed SMR devices and they show absolutely horrible re-silvering performance.

Without a relatively strong relations of linear write/read commands and their physical locations also being mostly linear, spinning rust performance is not on a usable level.

PixelOfDeath··on French Appeal Court affirms decision that copyright claims on GPL are invalid
> The GPL also has issues in Taiwan, apparently because it's illegal there to enforce its constraints on anything but the first user / immediate level.

NEW! License restriction free Linux source code for only $ 9.95 ! Only used once! ORDER NOW!

PixelOfDeath··on Samsung seemingly caught swapping components in its 970 Evo Plus SSDs
Enterprise prices are always negotiated in secret. We don't get to see what e.g. Facebook or Google pay for this devices.
PixelOfDeath··on Samsung seemingly caught swapping components in its 970 Evo Plus SSDs
Harder to find because they obviously do not market this things towards consumers. Except when selling consumers SMR drives without telling them. ;)

PixelOfDeath··on Samsung seemingly caught swapping components in its 970 Evo Plus SSDs
Yes many consumers will be fine with this drivers.

But the information about the limited write cache never gets mentioned by the manufacturers. So people that actually need to write large amounts of data from time to time, fall into a performance trap.
