Problem: Can't use sudo command-limiting in Ansible

The ability to limit sudo users to only be able to execute certain commands doesn't work with Ansible (without a workaround).

This isn't a problem if you're running Ansible as a super-user like root, but if you are allowing others to run Ansible on your systems in order to do things like application deploys, then you need a way to limit their access to the system for basic security.

For example, a line in /etc/sudoers like this:

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.

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

Check if italic font is supported:

$ echo -e "\e[3mitalic\e[23m"

Also check:

$ infocmp $TERM | grep sitm
 sgr0=\E(B\E[m, sitm=\E[3m, smacs=\E(0, smam=\E[?7h,

Installing MTGA on macOS using Wine, and making it look pretty!

The following instructions are heavily inspired by /u/uhohohdear. I modified uhohohdear's instructions and then added support for Retina/HiDPI displays and instructions about how to update MTGA.

IMPORTANT UPDATE: This will no longer work if you upgrade to macOS Catalina, as Wine and Wineskin are 32-bit. I'll update this Gist with 64-bit versions when they become available.

~~We're back in business!~~

It appears that the workarounds no longer work. A few people with Macs using Nvidia graphics cards are having success, but Macs with Intel and AMD GPUs crash regularly. At this time, the best way to play Arena on Mac is via Boot Camp or GeForce Now.
