Note that I have not tried all of these personally, and cannot and do not vouch for all of the tools listed here. In most cases, the descriptions here are copied directly from their code repos. Some may have been abandoned. Investigate before installing/using.

The ones I use regularly include: bat, dust, fd, fend, hyperfine, miniserve, ripgrep, just, cargo-audit and cargo-wipe.

In this article, I'll explain why implementing numbers with just algebraic datatypes is desirable. I'll then talk about common implementations of FFT (Fast Fourier Transform) and why they hide inherent inefficiencies. I'll then show how to implement integers and complex numbers with just algebraic datatypes, in a way that is extremely simple and elegant. I'll conclude by deriving a pure functional implementation of complex FFT with just datatypes, no floats.

The protocol uses a pair of rings, one for the senders, one for the receivers, represented as a singular ring. With each transfer, a list of ElGamal ciphertexts is provided for all accounts within the joint ring. This ElGamal ciphertext is formed as r * G, (r * K) + (a * G), where r is some randomness, K is the key for the account the ciphertext is for, and a is the amount.

Dero offers an 'encrypted message' with every transaction. Even if the user does not explicitly provide one, a message will exist (either with internally provided values or left empty). For the only defined type of message, the message is encoded as the index of the sender, a CBOR-encoded object, and zero-padding. The message is encrypted with the Chacha20 stream created by a key of H(H(r * K) || K) where r is some randomness and K is the key for the account the ciphertext is for.

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).
