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.

How to Eyeball Your ‘This’ Context in Javascript

by zach.dev

The early programmer struggles with the Javascript keyword this. But understanding your this context is easier than it seems.

This is all about where a function is invoked. Often, early programmers worry about where the function was declared. Perhaps the function was declared in a specific file or a particular object. Surely this changes it's this!

Nope.

When starting Emacs.app on Mac, the Emacs doesn't have some environment variable set correctly. Typically it is terrible when you use GPG, pinentry-mac, gpg-agent But also a lot of different variables used to make git works correctly, etc...

Solution

1. Create the file ~/bin/init-app-env.sh:

Taking back your Mandrill click-tracking links

My company, like many, has recently switched away from using Mandrill for our transactional email.

We'd been using Mandrill's [click-tracking][mandrill-click-tracking] feature, and became worried about what would happen to all those old emailed links after we cancel our Mandrill account.

Why should we care about links in emails sent a month or more ago?

Sublime Text talk cheatsheet

For Makers Academy Talk

Update 6/10/14 So I'm back at makers one day and I find out this list is still in use, and has been passed onto the new cohort as well! I'm so glad it is useful. With this in mind, I have updated it a little bit. There are now sections: Moving around open files and Split working areas. I hope these will be of use to you. Also a shout out to the awesome Tatiana Soukiassian who has carried on the shortcut love and created another fantastic list of keyboard shortcuts for sublime and beyond, listed by how essential they are. Much love Tatiana!!
