Dear [First Name],

We're really sorry but our systems were compromised and the attackers 
managed to take a copy of your passwords.

The passwords were stored as:

[ ] Bcrypt hashes with a cost factor of X
[ ] PBKDF2 hashes with an iteration count of X
[ ] scrypt because I am Colin Percival

# A pattern matching tool for jstack output. Can search for a pattern in the stacktraces,
# then show details of just the matching threads, either showing all of the stacktrace or
# just lines matching the search pattern, or matching any other patterns.
#
# For example, to see which threads are currently accessing the database and show the
# stacktrace lines containing your own classes:
# jstack-grep postgres <pid> -i com.xk72

Migrate from hosted GitLab to GitHub

In order to migrate from hosted GitLab to GitHub, I decided to use command-line git to mirror each repository from within the GitLab storage on our server.

The script uses the GitHub API to create a new private repository, and then uses the git command-line tool to mirror the repository.

The script keeps track of which repositories have been migrated by creating hidden .migrated-github-<repository> files. If you run the script again, these repositories will be skipped. This means you can re-run the script to recover from errors, such as a repository containing a file larger than 100MB (see https://rtyley.github.io/bfg-repo-cleaner/ for a solution to that).

If you choose to remove those files, you can still run the script multiple times as it mirrors the repository to GitHub. This approach could be used to pick up any changes made in GitLab before the final changeover to GitHub. But see the next paragraph...
