Well, a real experimental system is a quantum computer that 'calculates' the emerging behavior in real time. Sorry, that was needlessly sarcastic---actually, you have a good point there: it's ironic that we used digital comp

3.15 MJ is equivalent to 1.5 lb TNT, so it was quite a bang in their target chamber. Just for comparison, it's also just short of one kWh, so it would run an electric car for about three-four miles.

If you're using Intel architecture, it needs at least some SMM: it is used on startup (initial hardware configuration) and often during power management events (CPU clock scaling, hibernation, etc). The article mentions that they disab

I don't know the state of the art but I think that we can't even predict the static crystal structure of simple substances---e.g. when iron is BCC vs FCC. The first-principles simulation of dynamic properties of large quantum many

Multiple serial busses, each with its own clocking and buffer, so that the combined data is extracted synchronously at the end. The crosstalk is still a problem but there are ways around that: different twist rates for different pairs for i

You have to be careful using these burners in in-building enclosed spaces---they can produce carbon monoxide. They are really designed for open air use.

I had something like that hanging off a parallel port in a PC in 1990; it read the status bits of a printer port and booted accordingly. Could still do it today, via a $1 USB serial port's status bits.

I always clock screws in the electrical wall plates, for a vertical slot.

FWIW, TPM 2.0 can encrypt the TPM traffic, so the attack by physically sniffing the TPM ( https://dolosgroup.io/blog/2021/7/9/from-stolen-laptop-to-in... ) is no longer possible.

BBC Micro:bit has a 5x5 LED matrix that can be read by an analog GPIO, so you can play with reading back light levels.

boot windows safe mode, execute sysprep. This strips windows of hardware-specific drivers, so that qemu should have an easier time running it. The whole thing is crusty, and it may or may not work. It does change Windows, so make a copy and
