create bootable usb from .iso file on macOS
# if you want to boot a laptop from a USB drive and you have a file like archlinux-2017.07.01-x86_64.iso
# (and a USB drive plugged in), this is a script to copy the .iso onto the USB drive.
# like UNetbootin but debuggable.

Useful short prefix search engines for Chrome. Like adding DuckDuckGo bangs to google.

How to add DuckDuckGo bangs to Google (if you're using Chrome)

Chrome has a feature for defining your own search engines for the omni bar. It's intended for adding search boxes present on other websites, but it accepts arbitrary urls, including modified google search URLs. The URL for a google search query is just google.com/search?q=your+query+with+spaces+replaced+with+plus+signs, which means if you bind a "search engine" like google.com/search?q=wikipedia+%s to "w" you will automatically have the word "wikipedia" added to your search query if you search "w something". You won't even have to type the "!". Here's an example

Go to Settings → Manage Search Engines → Other search engines → ADD and then

Search engine: wikipedia

Keyword: w

Urbit ASCII character names

Hoon is Urbit's high-level programming language. It compiles to Nock, Urbit's low-level language.

https://urbit.org/docs/glossary/

Hoon code makes heavy use of non-alphanumeric symbols. Reading off code aloud using the proper names of ASCII symbols is tedious, so we've mapped syllables to symbols:

ace [1 space]       gap [>1 space, nl]  pat @

Which modules are imported in the Python standard library most often?
#!/usr/bin/env python3
# This script scans all .py files in cpython/Lib, finds all import statements
# in them and counts out what is imported most often in each top directory
# or file in Lib/ (meaning if some library is imported many times in various
# files in e.g. Lib/http/ , it will only be counted once).
#
# Clone the CPython repo then put this file in the top level cpython/
# directory and run it:
