Soldered storage is extremely uncommon for laptops not from Apple. You pretty much only find it in very low-end Chromebook type hardware that's using eMMC for cost reasons, and a small fraction of more expensive Qualcomm-based laptops

Did you really mean to say that audiophiles can distinguish between no distortion and some distortion, but cannot distinguish between more distortion and less distortion?

I don't think there's much need to worry that putting the blame on the humans rather than the bots would lead to the people selling footguns going unscathed. It doesn't seem plausible to me that people would be willing to pla

This seems to have parallels with the well-established practice of giving bots free reign to issue DMCA takedown notices (or similar but legally distinct takedowns) while the humans behind the bots are shielded from responsibility for the o

That's entirely you choosing to ignore real and relevant products that Apple shipped during the time period you claim they were doing nothing. If you're looking for some kind of absolute consistency in when and how Apple uses the

Selling an old model for a few years after its replacement shows up is not unusual. The only thing unusual here is that the 12" MacBook didn't end up actually replacing the MacBook Air in the long run, and the next major iteration

It would also be fair to say they didn't skip any generation of processors with that gap in updates, they merely sat out the first two years of Intel shipping Skylake five years in a row. And in the meantime, they did use those fir

Whether that's true or false depends on what your hypothetical developer wants to do in the future. When an all-new driver is written in Rust, then working on that driver will require knowing Rust. But nobody's talking about try

Sure, but that same deal was also unprecedented in how much less control the carrier got, and marked the beginning of the end for carriers owning the user experience on phones.

Windows laptops have been pretty much exclusively NVMe for years . The 2.5" SATA form factor was a waste of space that laptop OEMs were very happy to be rid of, first with mSATA then with M.2 using SATA or NVMe. NVMe finished displaci

That link says the Bertrand paradox only applies when the domain of possibilities is infinite. That doesn't seem to cover tasks like randomly selecting people from a finite population.

It's very common for both NVMe and SATA drives that they'll be locked/frozen during boot and thus will not honor a secure erase command until the drive has been power-cycled, which can usually be accomplished with the system-

If compliance is the goal, just use FIPS certified self-encrypting drives and trust them to wipe their encryption keys when instructed to do so. At that point, any failure is clearly the vendor's fault, not your own.

Since he was touting that they recently hired a well-known GPU architect, it seems unlikely that this is merely about them using their own fabs for discrete GPUs instead of having integrated GPUs being the only ones they fab themselves. Som

What needs to be plausibly denied is the existence of a second user account, because you're not going to be able to plausibly deny that the account belongs to you when it resides on the phone found in your pocket.

NAND flash has overprovisioning even on a per-die basis, eg. Micron's 256Gbit first-generation 3D NAND had 548 blocks per plane instead of 512, and the pages were 16384+2208 bytes. That left space both for defects and ECC while still b

My favorite example of this is how Windows NT has had async IO forever, while also being notorious for having slower storage performance than Linux. And when Linux finally got an async API worth using, Microsoft immediately set about clonin

It sounds like you're reasoning starting from an assumption that any claimed slowness of TCP would be something like a fixed per-packet overhead or delay that could be isolated and added back in to the result of your local testing to g
