I'm a little bit surprised that Apple hasn't moved beyond 128-bit NEON, either with a custom 256 bit extension, or with an early implementation of SVE. This seems to be an area where vertical integration of software makes transiti

My recollection is that when P. A. Semi was acquired by Apple, a major part of their "secret sauce" was a custom cell library. And then Intrinsity, a few years later, also seemed to be using custom cells on Samsung's process.

Yes, at various levels of the stack. One thing worth checking out is TI's "Hercules" processor family, which is a low-cost, entry level, but very well implemented "safety processor." If uses a combination of ECC (no

Cosmic rays aren't the only source of SEUs (single event upsets), but they're definitely a major one. One obvious data point: A very strong correlation between altitude and SEU rate.

Whoops! My mistake, thanks for that! I has been looking only at the Pro out of habit, but this might push me towards the non-Pro this generation.

One of the challenges of using a large-screen device in the sun is that most screen technologies (including transmissive LCD and OLED, but excluding eInk and transflective LCDs) are inherently "black" -- they absorb light energy t

The 16" MacBook Pro has a 100 W*hr battery. This is the limit of what the FAA considers a "consumer sized battery" [1], so going larger would restrict the ability to take them on commercial airplanes... [1] https:/&#x2F

Yes. The best-known exception is IBM's recent(-ish) power processors, which use large eDRAM as a last-level cache. As far as I know, there's no widespread use of eDRAM on processors smaller than 14 nm.

In the M1 processor, DRAM is on-package, but not on die. (Even large eDRAMs sharing a die with logic don't currently reach to gigabytes.) How far can DRAM-on-package go? NVidia just released a GPU with 96 GB of HBM on package (80 GB en

Keep in mind that, while the current phone system is very much electronic, the phone system historically predates electronics. It is electric, but not inherently electronic.

Verifiable public votes are the one piece missing for a successful "cash for votes" program, which many people (including myself) would consider highly undesirable, and even a perversion of democracy. Over $14B is being spent on t

Ion engines need a lot of power, but scale down quite well to lower powers and lower thrust. And even with an ion engine, you'd only be running it for a few years at the beginning of a mission. Meanwhile, one of your major power draws

Thanks to both you and coddingtonbear for the clarification. I updated the English and Simple English Wikipedia pages to refer to "grain" instead of "corn."

Ah... I thought I was familiar with most Britishisms that would lead to this level of confusion, but definitely was not familiar with this one! That explains it, thanks.

To further my confusion on this point, I notice that the Wikipedia article on Pliny's Naturalis Historia mentions: 'Some technical advances he discusses are the only sources for those inventions, such as hushing in mining technolo

Can't access the page, but one solution I would explore (and suspect has already been explored in depth) would be use of a stiffening treatment (heavy starching) rather than sacrificial sandwich materials. Many fabrics can be starched
