iTerm2 Key Bindings

Keys	Config	Desc
`⌘` `Del`	send hex 0x15	delete line
`⌥` `Del`	send hex 0x1B 0x08	delete word
`⌘` `←`	send hex 0x01	move cursor to the beginning of a line
`⌘` `→`	send hex 0x05	move cursor to the end of a line
`⌥` `←`	send esc seq Esc+b	move cursor to the left by word
⌥ →	send esc seq Esc+f	move cursor to the right by word

Open the iTerm preferences ⌘+, and navigate to the Profiles tab (the Keys tab can be used, but adding keybinding to your profile allows you to save your profile and sync it to multiple computers) and keys sub-tab and enter the following:

Delete all characters left of the cursor

⌘+←Delete Send Hex Codes:

0x18 0x7f – Less compatible, doesn't work in node and won't work in zsh by default, see below to fix zsh (bash/irb/pry should be fine), performs desired functionality when it does work.
0x15 – More compatible, but typical functionality is to delete the entire line rather than just the characters to the left of the cursor.

Delete all characters right of the cursor

⌘+fn+←Delete or ⌘+Delete→ Send Hex Codes:

0x0b

Thread Pools

Thread pools on the JVM should usually be divided into the following three categories:

CPU-bound
Blocking IO
Non-blocking IO polling

Each of these categories has a different optimal configuration and usage pattern.

- Inexplicable perversity of human nature.
- The clever machinations of MongoDB's marketing people.
- The AGPL license killed it.
- We spent too long development before monetizing.
- Bad performance.
- Numeric types limited to a 64-bit `float`.
- Great product, but didn't/couldn't translate to revenue.
- Bad business model.
- Failure in timezones/timestamp nuances.

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

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

	❱ git config user.signingKey 38AF394C
	❱ git config commit.gpgSign true
	❱ echo "test" \| gpg --clearsign
	-----BEGIN PGP SIGNED MESSAGE-----
	Hash: SHA256

	test
	gpg: signing failed: Inappropriate ioctl for device
	gpg: [stdin]: clear-sign failed: Inappropriate ioctl for device
