Not OP, but I had a very similar high school experience. I basically have two "stable" sleep rhythms: Go to sleep at 4 am, wake up at ~1 pm (the "lazy person" cycle), or got to sleep at 6 pm, wake up at ~3 am (the "

All of the algorithms are considered secure by the cryptographic community. You don't have to win a NIST competition to be considered secure, most if not all of the AES competition finalists that didn't win are also still unbroken

We have had something "theoretically secure" for like 40 years now, current research is more about how to make those ideas usable in practice (and ideally stateless), so I don't share your pessimism here. Those ideas are also

Pretty interesting that those guys took what are essentially joke passwords. Seems like they probably didn't expect anyone to bother trying to crack them.

The calculator is fun to play with, but as someone from Europe, goddamn what's going on in San Fransisco? You get almost double the salaries compared to Germany/Sweden etc., and significantly more than in NYC - rent must be insane

First of all absolutely, but more importantly who cares about the performance of your json parsing? I can only think of very few applications where that would be relevant at all, even if you care about performance in general.

It's not an arbitrary number on Intel's CPUs either, it's just still not very useful. Or at least it's not useful as an indicator of some sort of technological progress. If you limit a 3900X to 3900 clock speeds and volt

It uses fans, however IIRC the fan curves are such that they only kick in if you render videos or do something else that 100% uses the CPU, and even then they are fairly quiet. And again, if you simply limit the clock speeds and voltages, y

You don't really need any case airflow at all, it just depends on how much performance you're willing to sacrifice. Case in point, you can run cinebench on an 8700K without any cooler at all: https://www.youtube.com&#x2

I don't doubt that this works in theory. I just don't think this effect is relevant in practice (with the same manufacturing process). Especially because with lower resistance you can usually decrease the voltage too.

>140W is considerably closer Closer, yes, but more useful? Both are off by a mile - not to mention that TDP isn't supposed to tell you a chip's maximum power consumption in the first place. It's supposed to tell you how go

> For users who have a fixed TDP budget, there's a substantial difference. I really, really don't see how. Both TDPs have very little connection to how much power the chips actually pulls at full load. 105 to 140 isn't use

Yeah and those chips are typically the ones being sold as higher TDP chips.

Not sure what you're getting at, this is the same socket as all the other Ryzen 3000 CPUs... Not to mention that every slightly larger air cooler is a "passive cooler". Just don't connect the fan. Or set a fan curve that

by pingyong 7y ago
If that difference exists, I'd be very surprised if it was even measurable with normal methods. Since on modern x86 CPUs most of the chip is literally just dead / not doing anything at idle. But feel free to surprise me in case so

The 3900X still uses ~140 W at full load with a 105 W TDP. And still just like Intel, if you limit the clock speeds you can make it use 105 W, 65 W, or 35 W at full load, just like with Intel chips. AMD calculates the TDP a bit differently,

by pingyong 7y ago
Are people still impressed by low TDP numbers? Everyone can manipulate that number to anything you want by changing the base clock. Intel could sell the 9900K with a 25 W TDP by saying the base clock is 1200 MHz, AMD could do the same. (I m

You have a point tbh. There are simply way more jobs for people to do simple web programming and making UIs that are essentially just DB interfaces for people who can't write SQL statements. It's boring, but it can still be hugely
