GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
2. Create or import a key -- see below for https://keybase.io
3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

Expressions in string interpolation

During the fives episode of the [scalaprofies podcast][SP] the two Speaker where questioning for a special string interpolation that shows the definition of parts instead of evaluated result of the expressions. Invalid expressions should be still rejected by the compiler and refactoring tools should also affect the expressions within the string interpolation. Here we will implement such a functionality and see the tip of the of the iceberg of macros and string interpolation.

Example:

scala> def f(x: Int) = x * 2

# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env
# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced
# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start
# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running.

# Add the following to your shell init to set up gpg-agent automatically for every shell
if [ -f ~/.gnupg/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
    source ~/.gnupg/.gpg-agent-info
    export GPG_AGENT_INFO
else

Use AWS CLI and jq to do some things

I'm just getting up to speed on AWS, and so I'm learning my way around the CLI. It's nice and easy to do lots of things from the CLI, like querying, creating and destroying instances and images. There are lots of fiddly bits involved in parsing output so it can be used by a script or something, though, so here are some notes.

Tools

AWS CLI

Obviously you need the AWS CLI. It's an easy install using pip. Go here to find documentation and other install methods.
