Shorter and more secure alternative with elliptic curve zero-knowledge proof - for example with a 160bit curve you could have a 240bit (30 byte) licence key comprised of a 160bit f…

Making test points for all your testable functions and aligning them to a stripboard really simplified making a testing jig. You can solder some pogo pins to the strip board and ju…

The algorithm for the first example reads just like an implementation of a SAT solver. Set a variable, propogate clauses, backtrack on conflict (learn new 'rule' from conflict).

Maybe add a definition of 'risk' in the quick summary. It tends to man different things to different people, and linking back to a definition (e.g. the effect of uncertainty on obj…

the same way that if you lift for 3 months, it achieves nothing. I'm probably missing the point - but that first 3 months of training is where you make the fastest growth and can d…

Misleading title, should be changed to 'Why we moved from flopnax to rilkef and you should too'.

For some of the unsupported targets there is the Rust->C compiler. Haven't used it myself but I've seen that, for example, the ESP32/ESP8266/Xtensa is supported by it.

From memory WeChat verification only allows one verification every few months (and only if your account is old enough). In theory you can get a hostel employee to verify you, but t…

A useful example project would be an FFT or OFDM accelerator for a microcontroller. Most microcontrollers really struggle with FFT so it is an example where a small uC and a small …

Sometimes 1.1.1.1 is used as a testing value, and can get blocked for reasons. CloudFlare is getting a huge amount of spam IP traffic to 1.1.1.1 from misconfigured equipment, it wo…

Probably also because ammonia is polar, three positive protons and an electron pair in a tetrahedral arrangement. Whereas H2 is two protons hiding an electron pair in a linear arra…

Circa 1992.

Listened to American Kingpin on audiobook during a recent trip. It was pretty entertaining if anyone wants more information on this topic.

If you have a look at any Zachtronics games you can see one way of doing it. It is just a leaderboard represented as a histogram. A separate one for instructions, cycles, etc. No n…

It depends how often you want to update things I guess. A wildcard costs less than $50 a year these days, so if that might be better for some people than renewing their LE every fe…

The other option is to register a domain and use that to get either LetsEncrypt cetts or purchase a wildcard.

Additionally, the accuracy of the PCB fab when drilling holes is going to be better than when routing the edges of the board. Just need to ensure you pick a hole diameter that matc…

I'm not really following the trapdoor reasoning. Both RSA and elliptic curves are based on having a system where 'exponentiation' commutes and the 'logarithm' is computationally di…

From memory, GCC does one NewtonRaphson iteration on the approximate result so the error is much lower (closer to e-9 from memory again). They don't use the approximation directly …

Sure,but you are judt bolting one heat engine to another (the motor). I'm assuming the efficiency of the motor is better than the TEG (generally the case), so why not just draw pow…

It is the inverse of the square root. If you want to normalise a vector, you divide the components by the length. The length is the sqrt of the sum squares (Pythagoras). Divide is …

Heat engines generate work (power) through the movement of heat from hot to cold. Conventional systems (steam turbines, Stirling engines, regular thermoelectric generators) require…

Anyone trying to work out if Mikrotik has some equivalent of this SQM, looks like no. Well, not explicitly fq_codel or any extensions. Though using the sfq queue system with traffi…
