An ode to Math, the Queen of Sciences. At the foundation of every scientific knowledge is either a fundamental formula, equation, integral, derivative, or operation. Chemists, biologists, and physicists solve equations. Economists and businessmen optimize a non-linear problem with several constraints. Law professionals apply logic to an ambiguous rule set either to convince one another or to judge another's argument. Thus Math is everywhere. Pursuing knowledge in math is a fundamental inquiry of human nature and the underlying action in every scientific endeavor.

I'm starting a new series of Back to Basics blog posts. The first one is "What the hell is an Elliptic Curve?". Check it out:

Hey, I won a #COLDCARD on Atlanta #bitdevs today in the nonce guess game! @DETERMINISTIC OPTIMISM 🌞

Always verify the randomness of your wallet mnemonic generator. In a recent situation a bunch of wallets generated using bx, that, under the hood, uses a unsafe Mersenne Twister pseudorandom number generator (PRNG) initialized with 32 bits of system time. With a gamer computer and some hints on wallet creation time you can brute force the wallet creation time to deterministically generate the wallet mnemonic and <poof> money is gone....
