How to use this gist

You've got two main options:

To diff common binary files in git using appropriate external converters such as unrtf, pandoc, docx2txt.pl, odt2txt, git-xlsx-textconv, git-xlsx-textconv.pl or pptx2md, add to ~/.config/git/config the lines

[diff]
  [diff "pdf"]
    binary = true
    # textconv = pdfinfo
    textconv = sh -c 'pdftotext -layout "$0" -enc UTF-8 -nopgbrk -q -'
    cachetextconv = true

The following is taken from a brilliant answer on unix.se. Posting it here for personal reference. The question was:

What kind of patterns can I use in zsh parameter expansion?

${var//pattern/replacement} is using zsh wildcard patterns for pattern, the same ones as used for filename generation aka globbing which are a superset of the sh wildcard patterns. The syntax is also affected by the kshglob and extendedglob options. The ${var//pattern/replacement} comes from the Korn shell initially.

I'd recommend enabling extendedglob (set -o extendedglob in your ~/.zshrc) which gives you the most features (more so than standard EREs) at the expense of some backward incompatibility in some corner cases.

You'll find it documented at info zsh 'filename generation'.

How to notarize a Unity build for macOs 10.15 Catalina

As of January 2020, all apps running on macOs 10.15 Catalina are required to be notarized. For Unity games distributed outside the Mac App Store, such as with Steam, the notarization process is done post build using a series of Xcode command line tools.

Prerequisites

a Mac that is compatible with macOs 10.15 Catalina :
- MacBook (2015 or newer)
- MacBook Air (2012 or newer)
MacBook Pro (2012 or newer)

How to setup a practically free CDN using Backblaze B2 and Cloudflare

⚠️ Note 2023-01-21
Some things have changed since I originally wrote this in 2016. I have updated a few minor details, and the advice is still broadly the same, but there are some new Cloudflare features you can (and should) take advantage of. In particular, pay attention to Trevor Stevens' comment here from 22 January 2022, and Matt Stenson's useful caching advice. In addition, Backblaze, with whom Cloudflare are a Bandwidth Alliance partner, have published their own guide detailing how to use Cloudflare's Web Workers to cache content from B2 private buckets. That is worth reading,

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

	# - Bump your current 3 digit git tag (you MUST be using x.y.z format) by git tagging
	# `make release bump=major`

	# `make release`
	# - Build/publish your Python package via setuptools, dynamically inserting the bumped
