How to recover a dropped stash in Git?

1. Find the stash commits:

git log --graph --oneline --decorate ( git fsck --no-reflog | awk '/dangling commit/ {print $3}' )

This will show you all the commits at the tips of your commit graph which are no longer referenced from any branch or tag – every lost commit, including every stash commit you’ve ever created, will be somewhere in that graph.

The easiest way to load the Mysql Time Zone tables from your Mac OS time zone fields is via this command:

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql

However, on many systems like mine that will fail because some of the time zone information is incompatible with the database schema for the time zone tables.

Therefore, you'll want to load the time zone information into a text file and edit it to only include the time zones you need. (Or, attempt to find the data breaking the import.)

mysql_tzinfo_to_sql /usr/share/zoneinfo > zone_import.sql

Not all random values are created equal - for security-related code, you need a specific kind of random value.

A summary of this article, if you don't want to read the entire thing:

  • Don't use Math.random(). There are extremely few cases where Math.random() is the right answer. Don't use it, unless you've read this entire article, and determined that it's necessary for your case.
  • Don't use crypto.getRandomBytes directly. While it's a CSPRNG, it's easy to bias the result when 'transforming' it, such that the output becomes more predictable.
  • If you want to generate random tokens or API keys: Use uuid, specifically the uuid.v4() method. Avoid node-uuid - it's not the same package, and doesn't produce reliably secure random values.
  • If you want to generate random numbers in a range: Use random-number-csprng.

You should seriously consider reading the entire article, though - it's
