To sign Git commits, you need a gpg key. GPG stands for GNU Privacy Guard and is the de facto implementation of the OpenPGP message format. PGP stands for ‘Pretty Good Privacy’ and is a standard to sign and encrypt messages.

Setting up

Install with Homebrew:

$ brew install gpg

// Turns out this was not too difficult.
// By using the event loop as a global mail box ordering is even guaranteed for messages between only two actors.
// TODO would like to try and put one actor in a web worker to get some real parallism
// TODO would like to handle errors and have the concept of a deceased actor while a reference to an actor still exists. Probably involves creating an actor system like in Scala. Eurgh.

var actor = {
  send: function(message) {
    var self = this;
    console.log("sending to:", self);
    setTimeout(function(){

Seamlessly editing remote files in (Neo)Vim with Netrw and scp

Neovim and Vim both come bundled with a standard plugin called Netrw. Netrw acts a file explorer (similar to NERDTree), but more importantly has the ability to work with scp (as well as sftp, rcp, ftp, and lots of others :h netrw-nread) to let you edit files and browse directories that are hosted on a remote machine, inside of your local Vim instance.

This is useful since you are able to use your Vim setup and plugins without copying over your dotfiles to the remote machine. As well, since the file is copied to your local machine, there will be no delay when typing.

Setup

This is optional for Vim, but required for Neovim (check this Neovim issue explaining why).

Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

• Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
• Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
• If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
• If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's
