Car thieves have been using antennas to remotely trigger the keyless entry to great success here in Canada. Many people leave their keys on their doors so you just need to put a range extender against the door and scan cars in front until o

We use it at work to send FSMs over the network for distributing tasks. Admittedly we always do this with continuations that haven't started yet, but there is no technical reason we couldn't serialize the already started ones (alt

Scala async coroutines build FSMs that are just standard objects. They aren't very commonly used, but the same approach could probably be adapted to C. Basically the compiler compiles async function to a very simple FSM object where ea

For context, I came across this because I was interested in how they came to acquire the Twitter four-letter twitter handle @meta, which I wrote about here https://twitter.com/cyri77e/status/1453886080789405707 Tu

I don't think it would be a good idea, given that you'd have to claim the winnings. It might work once or twice but not over and over again. Additionally in most cases I'd think the lottery odds would be lower than the cost o

The more renewable energy that is built , the cheaper it gets. We now know that there is a cartel of US miners trying to create "clean" bitcoins (in part to appeal to Tesla and Musk) that will sell at a premium. https:/&#x2

Here is pattern matching as a library that is not built using statements, https://github.com/santinic/pampy Clearly it's possible. It's also more ergonomic than PEP 622.

I guess it comes down to whether one does the cost benefit analysis for society as a whole or for individuals. While decentralized permissionless markets can (and have) helped some individuals escape economic restrictions (capital controls,

The majority of people have wealth in real estate and generate income from wages, both of which are inflation neutral. In contrast, the rich are much more likely to have bonds or cash holdings. They are the ones for whom inflation is a real

That's been the problem with the Google result too, even though they did have "controlled" operations. They basically showed that a quantum computer doing random operations has an output that is difficult to predict with clas

Yeah that's what I mean. This is the case for both commercial software (eg Q-Chem) and free software. This is not to say that the boot time is always a problem, there are plenty of applications in which it doesn't matter at all (a

why? I commonly do things like screen 10,000 molecules for some property by calling a Fortran program 10k time. If each run takes 60s of compute, the 10s boot from Julia (over the nfs disk) would be pretty significant. Using Julia in this c

The wavefunction of an n qubit system is representable by a 2^n vector of complex numbers [1]. Using single precision floats [2], a 10 qubit wavefunction is 8 KB, 20 qubit = 8 MB, 30 qubit = 8 GB and 40 qubit = 8 TB. Hence a run-of-the-mill

Correct. There is a lot of arguments around that quantum computing will scale in a Moore's Law way (wrt qubits, so doubly exponential in compute power) and thus will be useful in the near future. These are extremely optimistic. Quantum
