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.

Strings

`String.prototype.*`

None of the string methods modify this – they always return fresh strings.

charAt(pos: number): string ^ES1

Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

Pimping Up Your PowerShell & Cmder with Posh-Git, Oh-My-Posh, & Powerline Fonts

Backstory (TLDR)

I work as a full-stack developer at work. We are a Windows & Azure shop, so we are using Windows as our development platform, hence this customization.

For my console needs, I am using Cmder which is based on ConEmu with PowerShell as my shell of choice.

Yes, yes, I know nowadays you can use the Linux subsystem on Windows 10 which allow you to run Ubuntu on Windows. If you are looking for customization of the Ubuntu bash shell, check out this article by Scott Hanselman.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

	After automatically updating Postgres to 9.6.1 via Homebrew, the pg_ctl start command didn't work.
	The error was something like "database files are incompatible with server".

	Database files have to be updated before starting the server, here are the steps that had to be followed:

	# need to have both 9.6.1 and latest 9.5.x installed, and keep 9.6.1 as default
	brew unlink postgresql
	brew install postgresql95
	brew unlink postgresql95
	brew link postgresql
