Better gate control results in lower leakage compared to fins, and there are probably also some better thermals associated with this approach due to the surrounding metals. However…

And on top of that, you can make almost any material lase. There have been entertaining experiments where folks used yogurt, apple juice, hair dye, and other fun liquids in pumped …

I'm afraid that's not even remotely true. Just two counterexamples: - MLC flash storage devices use multiple levels to store/retrieve bits [1], - Lots of control systems are implem…

That's indeed done all the time in electronics: for example, RF CMOS usually trailing on a node three or four generations behind the bleeding edge. However, all-optical/photonic co…

In principle, yes, but: - lower wavelength light is harder to confine within waveguides (or transmissive optics), and messes up atoms when colliding (think of x-rays), - finding an…

Switching/routing usually requires significant information processing (e.g. decode packet header, match destination address against routing tables, etc.). This necessitates 10k or …

No - that's just a neat trick to enhance the precision in the measurement of non-commuting observable quantities of interest.

In reality, all-optical computing is mostly a terrible idea: fundamentally, it cannot reach the integration density of electronics. It boils down to the elementary differences betw…

That is an extremely common practice in the industry. Every large chip design house does this to maximize line yield - it is called "binning" [1]. [1] https://en.wikipedia.org/wiki…

No, that's just some marketing verbiage with no real physical correspondence.

So many hyperbolic claims that boil down to a moderate 33% area benefit with very little data about mundane things like long-term reliability, or process variation. Every time an a…

Linearity, on-state loss, pole-to-pole isolation, and breakdown will be atrocious. It makes for a nice clickbaity publication though.

That's a great re-implementation from some stuff I did eons ago [0]. BIOS passwords are indeed a complete joke as means to secure access. There are a bunch of vendors out there who…

I do not understand the proclaimed 3X increase of design cost per finfet node, particularly in the context of digital ICs. Most cell designs are highly repetitive, so the increased…

The bypass algorithms have largely remained unchanged when the industry moved to EFI. Most vendors (Lenovo, Dell, Acer, Asus, Toshiba, Fujitsu, ...) simply wrapped their bypass alg…

Apple is doing a much better job than all the rest of the PC vendors. Even those vendors that I haven't published keygens for [1] have just stupendously unsound bypass mechanisms f…

No, it won't: on the length scale of a chip, the power efficiency of an electrical-optical-electrical transmission line is an order of magnitude worse than direct electrical transm…

The GPU is still an ARM Mali T6xx which is mostly unsupported, i.e. removing Chrome OS and running "pure" linux is going to be dreadfully slow for lack of 2D/3D acceleration. It's …

If you get around replacing chrome OS with linux and reflashing the firmware with uboot, you'll lose GPU acceleration (3D and 2D). ARM is pretty shitty about releasing specs for th…
