Swap Alt and Control keys

One of the first things a MacBook user might do on a Chromebook is mistakenly hit the Alt key instead of the Control key because on a MacBook keyboard, you use the Command key for many keyboard shortcuts such as cut, copy and paste. And a MacBook's Command key is directly to the left of the spacebar, just as the Alt key is on a Chromebook. Thankfully, you can reassign the Alt and Control keys on a Chromebook. Just click your account profile picture in the bottom-right corner and then click the gear icon. From the Settings window, scroll down to the Device section and click Keyboard and then assign the Ctrl key as Alt and the Alt key as Ctrl.

Set up Linux (Beta) on your Pixelbook

Select the time in the bottom right to open your status area.

Under "Linux (Beta)," select Turn On

Once the Linux (Beta) is enabled, the Terminal app will appear in the launcher.

Podcasts for Data Science & Stuff

I asked the Twittersphere for data science (& tangentially-related) podcasts recommendations, and got a much bigger response than I expected with some really superb recommendations, so I created a gist with the suggestions I received. They're arranged alphabetically by name below, along with relevant Twitter accounts, links, and names of the hosts (if I could find them).

Shoot me a tweet @bennyjtang if you have more suggestions to add to this list!

Probably one of the easiest things you'll ever do with gpg

Install Keybase: https://keybase.io/download and Ensure the keybase cli is in your PATH

First get the public key

keybase pgp export | gpg --import

Next get the private key

	# Generate a new pgp key: (better to use gpg2 instead of gpg in all below commands)
	gpg --gen-key
	# maybe you need some random work in your OS to generate a key. so run this command: `find ./* /home/username -type d \| xargs grep some_random_string > /dev/null`

	# check current keys:
	gpg --list-secret-keys --keyid-format LONG

	# See your gpg public key:
	gpg --armor --export YOUR_KEY_ID
	# YOUR_KEY_ID is the hash in front of `sec` in previous command. (for example sec 4096R/234FAA343232333 => key id is: 234FAA343232333)
