6SixTy··on Hacking the Xbox 360 Hypervisor Part 2: The Bad Update Exploit
Fat or slim PS3? Mine experienced a YLOD circa 2010 while the slim that replaced it still works to this day.
6SixTy··on Hacking the Xbox 360 Hypervisor Part 2: The Bad Update Exploit
Both of them experience the same issue. Though it's a yellow light instead of the ring on the Xbox.
6SixTy··on Why it's so hard to build a jet engine
There's sort of two tracks when it comes to jet engines: commercial aviation and military. Commercial just focuses on efficiency, while military has other considerations to account for. And in both sectors there's plenty of European competition, US/EU joint ventures, and subcontractors/licensed manufacturing going on.

Europe does have enough aerospace talent to make a jet engine especially at the cutting edge, but there's a significant amount of tech transfer between the US and Europe happening at the same time.

6SixTy··on Zelensky leaves White House after angry meeting
Just because the US changing its mind about Russia changes NATO's dynamic as a whole does not mean that the Baltic states are immediately in danger. Poland and Finland are both nearby NATO countries that have experienced Russia's thumb directly with their own military industrial base or are developing one that would absolutely step in if need be.

Reminder that Finland is really close to St. Petersburg, the 2nd largest city in Russia with some pretty big cultural and military importance. Putin's done some fantastically stupid stuff in regard to the 2022 Ukraine war, namely resuming it, but he's probably not that dumb.

6SixTy··on EA Open Sources Command and Conquer: Red Alert, along with other games
Thing that's hard to communicate is that Vista was moving away from how older versions of Windows rendered their desktop and past art styles. With Pinball originally from Windows 95, porting it to leverage Vista's new graphics paradigm on top of the artstyle was probably too much work for a pack in game.

Though I do wish they contracted out a clone of Pinball instead of Purble Place.

6SixTy··on Framework's first desktop is a strange–but unique–mini ITX gaming PC
That model of Surface is nearing almost 8 years old by now. Not current by my standards. I'm thinking about the chance of existing tooling still being around to make a screen and slap into a laptop rather than if it existed at one point.

But yes, considering that Framework's Chromebook is/was expensive (over $1k) for the class doesn't give a lot of faith that the 12in model would be any different. Though that was equipped with a 2k screen and had a 12th gen i5, so I genuinely wonder what kind of meetings happened to ship out a premium Chromebook (a segment that does not exist)

6SixTy··on Framework's first desktop is a strange–but unique–mini ITX gaming PC
It's likely chosen for cost. There's a couple of brand new fairly cheap laptops with exactly the same screens on paper and a few other similar sized laptops that are in the ballpark.

Skimming Google, there are pretty much are no laptops 12" and higher resolution than 1080x1200 that's current nor made by Apple.

6SixTy··on Framework's first desktop is a strange–but unique–mini ITX gaming PC
Yes but Framework doesn't have to and probably doesn't want to. Snapdragon laptops often ship with very few user serviceable parts including RAM which would be tough for the Framework mold IMO even if they got something working with LPCAMM (though that's likely an inevitability). But Qualcomm making a Framework compatible board in part as development kits would likely be beneficial for both.
6SixTy··on Dogs may have domesticated themselves because they liked snacks, model suggests
Issue is that for domestication to be possible, there has to be a preexisting social structure like herding, colonies, or packs. If it's too weak or non existent, there's no chance that domestication is possible. Having docile examples are always going to be a thing, as snakes aren't exotic pets nor social by any stretch, but that's not what domestication is.

There's an additional risk with omnivorous/carnivorous animals could see people as prey, and this risk pretty much goes up with the size of the animal.

I have no idea how bears act with one another, but I do know they can eat meat and are basically person sized.

6SixTy··on Turning Off All 8k EV Chargers at All Federal Government Buildings
Word is that China makes getting a license plate for an ICE extremely hard to get, while EVs get basically a free pass.

I don't know about any direct subsidies but I wouldn't doubt that there's something there.

6SixTy··on Turning Off All 8k EV Chargers at All Federal Government Buildings
This is real. There's a bunch of federal vehicles that don't have cats in them, or the equivalent systems for diesel from the factory. They are exempt from emissions standards.
6SixTy··on Yugo Is Trying to Make a Comeback with a New Cheap Car
They would likely have to be modified to meet new safety, emissions, anti theft, etc standards to be able to sell them in the US... In other words, it would be a completely new car. Even old designs with a new date of manufacture have to meet these new requirements.

Not to mention that insurance will have a say about the ongoing costs of such a car. Some of the cheapest cars on a basic search to insure are SUVs or Crossovers.

6SixTy··on Valve releases Team Fortress 2 game code
I'm not. Source 2 is very modern even by caveman gamer standards.
6SixTy··on Valve releases Team Fortress 2 code
Considering that Source is ancient and likely hasn't gotten an update from at least 2013 for TF2, the bar is low for how complete an engine needs to be for level comparisons.
6SixTy··on Limine 9.0 Bootloader Drops EXT4 File-System Support
I've used Limine on one of my machines for a good while now. It is quite simply, a UEFI executable where you can point to something bigger, be it another bootloader or a kernel. Removing filesystem support is more or less an inconvenience since you can load up a kernel that can access that filesystem and you are good to go. Doesn't matter what filesystem, because the bootloader doesn't care.
6SixTy··on IPv6 Is Hard
NAT was invented to connect entire businesses to the internet that would otherwise have to manually reconfigure every single device for the internet. Keeping IPv4 going amidst address exhaustion going was a lucky coincidence of it.
6SixTy··on Ask HN: Why don't big tech companies unite to build an OS?
Serious questions: why and what's the point? You can pretty much mold Linux into whatever you want.
6SixTy··on Ukraine not invited to US-Russia peace talks, source tells BBC
"both fights" are presumably the Ukrainian war and Iraqi Freedom. Automotive power sources is oil.

What that all that means pretty much boils down to parroting Russian talking points.

6SixTy··on “A calculator app? Anyone could make that”
Sounds like he's just using stock math functions. Both Javascript and Python act the same way when you save the result immediately after subtracting two numbers multiple times, rather than just 8.7 - (2.9*3).
6SixTy··on The 20 year old PSP can now connect to WPA2 WiFi Networks
Problem is that from what I've read, the system firmware is embedded in a module that also serves as WiFi. There is a chance that the firmware could be hacked to enable WPA2, but probably not WPA3.
6SixTy··on Ask HN: Are there any interesting uses of Generative AI/LLMs in video games?
It's only dialogue I know of where there's a bunch of "next level" AI experiences coming through the pipeline. Generation of responses, translation, text to speech, and finally the movement of the face. Even then it's mostly targeted mostly towards otherwise banal scripted NPC dialogue, not story beat type of thing.

Can't really see much use aside from that or canning whatever the AI generated ahead of time. There's far too much potential for it to be jailbroken or loose track of what it's supposed to be doing.

6SixTy··on The Iconic 3DBenchy Enters the Public Domain
NAL either but D. J. Bernstein [https://cr.yp.to/publicdomain.html] says that you can use a work under public domain in Germany same as any other country (e.g. copying), but there's a separate right to be credited for the work where applicable and protection for the author's reputation.

So if I made Benchy longer and turned it into a rendition of the Titanic, I can't claim that it's 100% mine and no one else had a hand in making it under those rules.

6SixTy··on How Nissan and Honda's $60B merger talks collapsed
My theory is that a lot of auto mechanics are very mechanically minded, so if the problems start being electrical they don't have the equipment or the skill set to solve the issue beyond simple power.

I saw a video the other day where a Ram truck was having issues on the CAN bus after driving 33 miles and would settle down after 10-15 minutes. The tech was pretty much stumped and pretty much only figured it out by brute force. A capacitor on one of the CAN terminators failed making its capacitance higher than spec and screwed up the filtration harmonics after charging for those 33 miles.

There's also two sides to "reliable" where either it's simple to fix or never breaks down. Always keep that in mind whenever someone is talking about reliability because it's never obvious which definition someone has in mind.

6SixTy··on Nvidia's RTX 5090 power connectors are melting
Nobody thought that they could push 50A at 12V through half the connector. It's management wanting to push industrial design as opposed to safety. They made a new connector borrowing from an already existing design, pushed up the on paper amperage by 3A, never changed the contact resistance, and made the parent connector push current near it's limit (10.5A max vs 8.3A). And oh, the insertion force is so, so much higher than ever before. Previous PCIe connectors push about 4A through a connector designed for about 13A.

Worth also mentioning that the same time the 12VHPWR connector was being market tested was during Ampere, the same generation where Nvidia doubled down on the industrial design of their 1st party cards.

Also there's zero devices out there that actually deliver or take 240W over USB-C. Texas Instruments literally only released the datasheets for a pivotal supporting IC within the last 6 months.

6SixTy··on Apple software update “bug” enables Apple Intelligence
Difference is that Zigbee etc aren't vying for the same place that StarFlash/Nearlink,etc is for Bluetooth
6SixTy··on Apple software update “bug” enables Apple Intelligence
There is an alternative protocol for wireless communications, only problem is that it's Chinese. https://news.ycombinator.com/item?id=42443750
6SixTy··on RISC-V Mainboard for Framework Laptop 13 is now available
IIRC my X13s has experimental right next to booting Linux, and I doubt any of the newer models are better. Honestly not a great sign even though Windows forced the use of UEFI.
6SixTy··on RISC-V Mainboard for Framework Laptop 13 is now available
There's Verisilicon, Imagination, Broadcom, and probably even ARM licensing out GPU IP blocks to anyone with capital.

Getting AMD on board could be a little trickier but could be feasible with a compute SOC deal balancing the deal out (this is a pipe dream).

6SixTy··on The origins of 60-Hz as a power frequency (1997)
Very much true. A higher switching frequency means that a smaller transformer is needed for a given power load.

In reference to consumer power supplies, only reason why GaN power bricks are any smaller than normal is because GaN can be run at a much higher frequency, needing smaller inductor/transformer and thus shrinking the overall volume.

Transformers and inductors are often the largest (and heaviest!) part of any circuit as they cannot be shrunk without significantly changing their behavior.

6SixTy··on Fiwix: Small Unix-Like Kernel
RISC-V has plenty of reference documentation and implementation code from hardware to the OS Kernel. Open source and free too.

And running on real hardware is pretty much the last thing any OS dev actually does. Using a VM with a debugger attached rather than trying to figure out how to set up a debug harness is more convienent.
