Isn't the real reason to use char8_t over char that it that char8_t* are subject to the same strict aliasing rules as all other non-char primitive types? (i.e., the compiler doesn't have to worry that a char8_t* could point to any

Elpida was purchased by Micron after the financial crisis (they bought it out of bankdruptcy for a swan song in 2013). Much of the Micron DRAM you might buy is made at the former Elipida fab in Hiroshima.

They're also wrong in suggesting that J-1 visas are intended to just be used for "cultural exchange". They are quite explicitly intended for use by trainees[1]. I assume these folks are intended to be trained in New Mexico so

Thank you for the link to Robin Sloan’s blog and temporarily answering my question about whether I should upgrade iOS. I love his books and for some reason never thought to look to see if he wrote anything else online.

This just doesn't make technical sense. I completely agree that backdooring encryption standards is a bad thing. But Dual EC DRBG is a clear example of a NOBUS backdoor actually being that. The backdoor is equivalent to "knowing&q

If the refund is paid in less than 45 days after the tax filing deadline or the day you file your taxes, they will pay you interest. See here: https://www.irs.gov/payments/interest#pay

Plenty of actual research costs count as overhead to avoid the need to hire an army of accountants to allocate every single bit of spend. For example, the electricity costs of the lab in which the research is run would typically be paid for

I think the "X" looks like a pair of scissors. No good explanation for ZUndo though.

I like how you edited this to add "at work" after folks provided examples of it happening outside of work. If you'd like a slightly more work adjacent example, see the rampant increase in IEPs for students in the bay area. (I

How did you choose the process noise covariance in your `grad` function? It doesn't seem like a single process noise covariance structure should be globally applicable across all possible functions.

This headline kind of misses the point. The NTSB is very explicitly structured to not be a regulator to enhance cooperation between all parties, which is part of the reason that confidentiality is so important.

The tiny yellow blobs are the bonded lasers, so the locations of the bonded lasers in the subsequent figures are incorrect but still get the point across. This page from IMEC has a video actually showing some of the process. (The image at t

To be clear, you want to decrease the permittivity that adds capacitance where the accumulation of charge serves no purpose (i.e., in the interconnects) and increase permittivity where we want to have a lot of charge (i.e., on the actual tr

A red LED (or really any LED due to the physics of the type of energy transitions used to produce light with an LED) has a much shorter wavelength (significantly higher energy photons) than any type of EM wave sued for cellular connectivity

The more important reason this is not true is that there is technically feasible DIMM form factor for LPDDR4/4x/5/5x RAM. And there are actual power savings (~20% reduction in J/bit transferred) to be had for using LPDDR

The document layer seems to be unmaintained since the end of 2019 and has quite a few bugs. The 1.8.x releases fixed a bunch of bugs but also dropped transaction support. It honestly seems like a great idea, but I'm guessing no one at

That’s just not true? They have significant amounts of production in Arizona, some in Oregon (along with TD) and then the rest in Ireland and Israel (which probably aren’t much lower cost than Arizona)

This doesn't particularly make sense. You can't even use non Intel chipsets with Intel CPUs and integrated GPUs are inherently tied to the CPU. (In the case of the discrete GPU segment, Intel didn't even have an offering.) Th

It could only solve the two language problem if the "users" were writing their program in Julia themselves. Otherwise your ideal solution is still using two languages. And if they are writing their program in Julia, there's n

A typical new car practically lasts way longer than a car built 30-50 years ago, early 2-3x the value there. Account for significant reduction in chance of death, MPG improvements, and these numbers make complete sense.

This is most definitely not true. Trumpf makes CO2 lasers which are used by Cymer to produce EUV radiation via excitation of liquid tin droplets.

AMD and Intel don't actually own it all, certainly not from a software perspective. That's the difference here. The upshot of this article is that Nvidia basically wants to "CUDAify" the entire datacenter software stack.

That is not an Icelake chip. IceLake and Comet Lake are both "10th Generation" Core. Icelake was limited to more premium offerings and was only 4 cores and lower.

Mainly because what you're saying isn't true for many workloads? (Also this already works for most existing integrated GPUs.) The types of workloads run on GPUs typically like very high memory bandwidth and are usually willing to

No...the whole point is that the single instruction induced halt for downclocking isn't a real issue. Even in the pathological case where you insert a single instruction spaced 760 us apart in order to induce the maximum number of cloc

This isn't the real problem though...the problem with the existing AVX-512 implementations is the "relaxation time" causes subsequent scalar code to be slow. From later in the same post: > Here, we have the worst case scen

To reiterate, the problem with the existing license based downclocking is that a few AVX-512 operations can drop your frequency for subsequent scalar loads on the same core so you need to carefully analyze the overall application to make su
