>Choosing a random generator matters, because we want a different permutation every time, not simply a different starting point. Ah thanks, now it makes more sense, I knew I was missing something. What about choosing different prime poly

Even if RSA is broken tomorrow, we already have many other algorithms for asymmetric encryption that do not depend on factoring and can't be broken even with a quantum computer, like the McEliece cryptosystem. We only would need to cha

The problem of generating a non-repeating (2^n)-1 n-bit numbers permutation is equivalent to generating a m-sequence ( http://en.wikipedia.org/wiki/Maximum_length_sequence ) and the simplest way is a n-bit LFSR with a pr

Well, because of course it was not a mistake. Inflation is a way to transfer wealth from the general population to the guys with the printing press (The gov friends). The only way to escape this trap is to save money in a hard currency, for

Government highly regulates and practically prohibits the dollar here in Argentina. As a consequence, black market dollar is the only available and it's obviously more expensive. Huge inflation of 25% or more makes the black-market dol

I agree this is a much saner way to think about it.

Just remember that your software is not you. Have a tick skin, learn and start again. Probably a name-change will help too...

You are dangerously fooling yourself by minimizing the importance of those bugs. Cryptography software is not like regular software. It is critical software, like the kind used to run planes or nuclear power plants: People's lives depe

Not only you have to hack the routers, once inside the router you'll have to flash a custom wireless firmware, or "radio" firmware. And also the Chipset must be flexible enough to allow all the iFFT shenanigans. I think it's a stretch to sa

Indeed, in some countries (like mine) calling yourself an engineer while not having the real degree it's illegal, even if it's your job description. Incidentally, here (Argentina) we have the equivalent of farming engineer, called "Ingenier

It was when Donald Knuth wrote that, 50 years ago. Nowadays it is engineering. It is desirable for a programmer to build software, within a specific time, specific cost and certain specs. 100% Engineering. Now this is valid for 99% of soft

Nonsense. I work long hours debugging various kernels, including Windows, Linux and the *BSDs. The quality of the OpenBSD kernel is amazing. Maybe Minix is better, but that's because it's educational code.

I can see that unlike a 3d-printer, it's impossible to have a CNC in your desktop because of the waste. But I don't buy the "community" argument. Community has given us things like the arduino, a horrible technology obsolete from the very s

IMHO 3d-printing is way overrated. We already have CNC machines that are reliable, faster, cheaper and more capable than 3d-printers, in that they can cheaply "print" in hard materials like metal with much better resolution. What are the ad

No physicist here but I think there may be losses in the interface air/glass. Also, air contains water and other elements that may present too much attenuation at 1550 nm. I suspect the different lambda is one of the reasons of the limited
