Most of cell energy density comparison don't remove cell casings mass from comparison. This way pouch cells outperform hard cased ones so much on capacity, but in reality it's a big delusion as you still have to put structure to h

Poulsbo was disastrously bad, quirky, and impractical. It took all x86 platform warts, and replaced it with even harder to get right "Poulsbo warts" like SFI, and etc.

I was expecting the "where it collides with reality" to be at least somewhat touch the nuclear war topic with 3 players. Even the name of the trilogy is an allegory on the "three countries" — a historical novell any Chin

Most CADs are already history based, and in fact can't work without it. A much bigger challenge is to make a historyless CAD AKA "direct modelling" I honestly admit, I failed to understand how geometry solvers of direct model

It's now nearly impossible to build a web browser from scratch because of runaway explosion of web browser features, and proprietary API extensions. W3C here is unfortunately a part to the problem. Standardisation is good, but letting

PCI is quite power hungry when it works on full trottle. The seemed power efficiency when PCIE was going 1.0 2.0 3.0 ... was due to dynamic power control, and link sleep. On top of it, they simply don't haul memory nonstop over PCIE an

Actually no "extra" chip area in comparison to x86 based solution. They just throw away so much of cruft from the die like PCIE PHYs, and x86 legacy I/O with large area analog circuitry. Redundant complex DMA, and memory con

So, now we know that LPDDR5 will be coming with at least 16GB per die stack. A doubling from LPDDR4. One package = 128 bit, a double of regular DIMM I/O width. I see, it's not too much behind even HBM2, of which we may never see a

The problem is not understood by the prime majority: As said above, the performance, and power consumption of modern CPUs is an "all, or nothing" choice. Modern laptop CPUs are nothing, but well disguised desktop/server cores
