Ratiofarmings··on Hacked Nvidia 4090 GPU driver to enable P2P
In cases where they didn't, the techpowerup vBIOS collection solves the problem.
Ratiofarmings··on How might software development have unfolded if CPU speeds were 20x slower?
Be careful not to mix slow CPUs with not having SSDs. A OS freezing up is almost always because something is broken or because it's waiting for a HDD to spin up.
Ratiofarmings··on How might software development have unfolded if CPU speeds were 20x slower?
We're definitely prioritizing features and just more applications and use cases over optimization. If CPUs were 20x slower, we'd probably see quite a few of the things that are possible right now. But with a lot more well optimized custom solutions rather than bloated frameworks.

And in some cases, multi-threading would be the only way to do things. Where right now, single-threaded file copy, decompression or draw-calls are largely a thing because it's way easier to do and there is no need to change it outside professional applications.

Also, some things might actually be better than they are right now. Having to wait for pointless animations to finish before a UI element becomes usable should not be a thing. If there was no CPU performance for this kind of nonsense, they wouldn't be there.

Please don't mix clockspeeds with performance. A Athlon™ 5350 from 2014 is >20x slower single threaded than a Core i9-14900K. Yet it's 2 GHz vs. 5.8 GHz. Architecture, Cache and Memory Speed matter A LOT.

Ratiofarmings··on What Restoring a 30-Year-Old Nintendo Taught Me About Right to Repair
Exactly. The problem isn't the advancement of technology. It's the rampant gatekeeping of manufacturers and both politicians as well as some of the user base defending it.
Ratiofarmings··on Top secret U.S. Navy system heard titan implosion days ago
Because dealing with it internally and informing the public are two entirely different things. They may well have told the families some things, but not the public. Afterall this is a privately funded venture and the rescue effort isn't going to be paid for by the public either. They owe us nothing.
Ratiofarmings··on Top secret U.S. Navy system heard titan implosion days ago
If it's only "probably destroyed" then it's perfectly reasonable to hold off on an announcement and to keep looking for a few days. You wouldn't want to tell the families that their relatives are dead and then go home without making sure you did what you could.
Ratiofarmings··on Submarine missing near Titanic used a $30 Logitech gamepad for steering
Also assuming that weight isn't an issue, the controller being $30 makes redundancy easy. Just like every other kid playing video games, simply have a second one in case the first one fails.

It's small, cheap and replaced in seconds.

Ratiofarmings··on Electric fan car shatters the Goodwood hill climb record
How lucky it has adjustable ride height and obviously doesn't run the fan outside of racing.
Ratiofarmings··on Electric fan car shatters the Goodwood hill climb record
There is an interview with the driver on the Archie Hamilton racing YouTube where he shows the wheel in depth including the paddles.
Ratiofarmings··on Electric fan car shatters the Goodwood hill climb record
There is no need to run the fans at all or at least not nearly at full speed on public roads. So I would expect the dust cloud to not be there during operation on public roads.

Also the output it filtered so there are no rocks or other debris thrown into the car behind. That was already the case on the prototype raced at Goodwood.

Ratiofarmings··on 13-inch MacBook Pro review: Apple’s M2 is a worthy follow-up to the M1
But there is the more up to date 14 and 16-inch model with a better keyboard, 120hz screen and updated chassis. This one seems to be some sort of thing to simply hit a price point for the entry level "pro" model. Faster charging, better display and fan for sustained loads, otherwise exactly the same.

Or to satisfy the needs of the few who actually do use the touchbar and don't want it to be abandonware after just two generations.

Ratiofarmings··on Ask HN: Why does my '15 MacBook Air have the same RAM (8gb) as a '22 McBook Pro?
True. I guess it's the slightly enhanced version of the M1 Air. Additional connectivity, touchbar and a fan for sustained loads. If that's not required, might as well save the $400 and buy an Air as they're the same in all other aspects.
Ratiofarmings··on Ask HN: Why does my '15 MacBook Air have the same RAM (8gb) as a '22 McBook Pro?
It is. It's the first M1 model still with the touchbar and the old display. So far it hasn't been discontinued, but de-facto replaced by the current 14 inch model.
Ratiofarmings··on Ask HN: Why does my '15 MacBook Air have the same RAM (8gb) as a '22 McBook Pro?
Because unless your applications need to store lots of things in memory, it doesn't matter for performance. macOS is very good with memory management, so for a lot of use cases 8gb is simply sufficient. The system as a whole is a lot faster than the '15 Air.

That being said, the lowest config is often something that is just there to meet a price point for advertising purposes, not what Apple actually expects people to buy. They've been doing this for decades. 16gb was the "standard" in 2015 already for most machines.

Ratiofarmings··on Core i9-12900KS World Record: How I Hit 7.8 GHz on 8 Cores
Look up Kingpin Roboclocker. That's the closest anyone has gotten to develop a fully automated system that could be developed into something you could run for extended periods of time in the right environment.
Ratiofarmings··on Core i9-12900KS World Record: How I Hit 7.8 GHz on 8 Cores
Well, partially with good insulation, Vaseline or plastidip coating.

And partially, you just don't. It'll freeze over and since this is for competition and not daily use, that is okay. Usually nothing gets damaged, sometimes it does. Extreme OC is expensive.

Ratiofarmings··on Core i9-12900KS World Record: How I Hit 7.8 GHz on 8 Cores
Actually they did it for a PR event with ASUS to get the record when the platform launched.

Liquid Helium is too expensive and difficult to handle otherwise. Even for extreme overclocking.

Ratiofarmings··on NASA: Tonga blast was 10 megatons, more powerful than a nuclear bomb
As a non-American, I have no idea what kind of damage hurricane Katrina did. As far as I am concerned, there was some wind. Enough to make international news, but that's about it.

But when I see "comparable to a nuke" at least I know immediately that this is a major event. A hurricane, powerful as it may be, is harder to grasp for a comparison.

Ratiofarmings··on Why can’t I play Ultra HD Blu-ray movies on my new Intel CPU platform?
It's like they're asking us to pirate everything.
Ratiofarmings··on Ask HN: Help me get my friend,a retired US Army officer, into IT management
Doesn't mean we need yet another one of those.
Ratiofarmings··on Ask HN: What are some things you learnt from a game that changed your life?
Honestly starcraft has taught me the opposite of that. It taught me that paying attention and making things up on the spot works well into 5k MMR (upper 90th percentile of performance).

It taught me that most people overthink. Then go and try to do fancy things without doing basic things correctly first.

I believe a fair amount of that translates into real life. People think too much about non important things and neglect the actually important stuff in the process.

Ratiofarmings··on Forget Google, time to end the Visa-MasterCard duopoly
So instead of sometimes one of the two not being accepted, you want me to carry 50 different ones and have 2/3 rejected?

No, thank you.

Ratiofarmings··on Neil Armstrong's reply to a Moon landing skeptic
That sounds like a good method, given the time. But I'd like to argue that some people are simply not smart enough to have enough reflection and thoughts about anything. They need someone else to feed them a theory that fits their view on the world. And that's that. No going back from it.
Ratiofarmings··on Ask HN: How to prevent audio downsampling with AirPods?
But why is the audio quality fine for example on a facetime call. If the two way standard is that bad, wouldn't it be universally bad?

Beyond that, is anyone working on a better one. I can see using AirPods as normal wireless headset if it wasn't for above described issue. They're great otherwise.

Ratiofarmings··on AMD’s Mobile Revival: Redefining the Notebook Business with the Ryzen 9 4900HS
If you do some text processing, some email and generally office software, 8gb is absolutely enough. Beyond that it's not anymore. 16gb is where most people with more serious applications are happy. The cool kids have 32gb. Anybody who needs even more knows it.
Ratiofarmings··on AMD’s Mobile Revival: Redefining the Notebook Business with the Ryzen 9 4900HS
While that might be true and I am happy that you're happy, this is something different. Intel has competitive products to your cpu, outright better ones, too.

To Ryzen 4000(mobile) they don't. It's not even close.

Ratiofarmings··on Amazon employees plan ‘online walkout’ to protest treatment of warehouse workers
It's nice that they thank their "essential workers" now.

Meanwhile all the essential workers are like. Cool. Where is the money though. A "thanks" gives you a warm feeling, but doesn't pay the bills.

Ratiofarmings··on Western Digital admits 2TB-6TB WD Red NAS drives use shingled magnetic recording
They bought HGST, not Seagate.
Ratiofarmings··on AMD’s Entire Ryzen 9 3950X 16 Core CPU Inventory Sold Out in Japan
So they sold like 50 CPUs in Japan?
Ratiofarmings··on Men Arrested at Courthouse Say They Were Sent to Test Its Security
So now, next question. Have they done anything in there. They've caught the intruders, good on them. But as a security guy myself I am asking: did they check ALL electronics for tampering as well as do a basic bug sweep.

I am not saying it was, in fact I don't think the courthouse who let's them rot in jail now gives a damn, but a thorough test could also test whether after catching intruders the court bothers to check their equipment. Something added/manipulated is sometimes worse than something stolen.
