1. Find the formula for the version you want to install:

   • Visit https://github.com/Homebrew/homebrew-core/tree/master/Formula
   • Click the file with your formula (e.g. “composer.rb”)
   • Click “History” (top right)
   • Click the commit hash for the version you want to download
   • Click the three dots (top right of diff) and choose “view file”
   • Click “Raw” and copy the raw URL from the browser address bar.

   For example, composer 1.10.15 lives here: https://github.com/Homebrew/homebrew-core/blob/9e6e6a1ca8551901bff69d329c7fbb9007064134/Formula/composer.rb

Exclude node_modules and .git from Backblaze backups on Mac

1. Edit the file at /Library/Backblaze.bzpkg/bzdata/bzexcluderules_editable.xml.
2. Add these rules inside the bzexclusions tag:

<!-- Exclude node_modules. -->
<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/node_modules/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />
<excludefname_rule plat="mac" osVers="*"  ruleIsOptional="t" skipFirstCharThenStartsWith="users/" contains_1="/.git/" contains_2="*" doesNotContain="*" endsWith="*" hasFileExtension="*" />

For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

• Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.
