Let's list here crates that enhance Rust as a language.

It not "batteries" like in stdx, but Rust-specific crates for workarounds for various missing features and experimental ideals from non-accepted/postponed RFCs, or just hacky tricks.

The list is supposed to contain (mostly) crates that are internal to Rust, not ones for making Rust deal with "external world" like other languages bindings, file formats, protocols and so on.

Primary focus should be on crates that are not easy to find by conventional means (e.g. no algorithm name, format or protocol to search for).

Note that quality of the listed crates may vary from proof-of-concept to stable-and-widely-used.

Understanding Kubernetes in 10 minutes

Original document can be found here; written by Mike Schuette.

This document provides a rapid-fire overview of Kubernetes concepts, vocabulary, and operations. The target audience is anyone who runs applications in a cloud environment today, and who wants to understand the basic mechanics of a Kubernetes cluster. The goal is that within 10 minutes, managers who read this should be able to listen in on a Kubernetes conversation and follow along at a high level, and engineers should be ready to deploy a sample app to a toy cluster of their own.

This orientation doc was written because the official Kubernetes docs are a great reference, but they present a small cliff to climb for newcomers.

If you want to understand why you should consider running Kubernetes, see the official Kubernetes conceptual overview document. This doc

I'm learning about SOPS and setting it up as my preferred mechanism for storing secrets. Here are my notes.

PGP

It’s security mechanism is that we (i.e. client) use a PUBLIC key from the receiver (i.e. server) and encode it with a random key (I’m saying nonce but it could be reused)

This varies from RSA and SSH because the server uses a PUBLIC key to identify the client.

Web of trust

Web of trust operates by still using PGP (i.e. encoding with recipient’s public key) but additionally, we can encrypt/sign the data as our own by signing it with the client’s private key.

This means the recipient will initially decrypt via our (i.e. client’s) public key (verifying the source) and then decrypting via their (i.e. server’s) private key to get the data.
