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

-- GEOIP IN POSTGRESQL
--

-- We use two approaches. First using PostgreSQL inet and cidr types and indexing (PostgreSQL 9.4 and later),
-- and then using ip4r (https://github.com/RhodiumToad/ip4r).
-- The performance of ip4r indexes is significantly better than PostgreSQL's own index.
-- An operation that took 42s using ip4r took 47 minutes using PostgreSQL's cidr index.

strongSwan setup for Road Warriors on macOS 10.12, iOS 10 and Windows 10

This setup is for remote users to connect into an office/home LAN using a VPN (ipsec). This is based on (but not the same as) the strongSwan documentation and this guide: https://raymii.org/s/tutorials/IPSEC_vpn_with_Ubuntu_16.04.html

I used strongSwan 5.5.1.

apt-get install -y strongswan strongswan-pki

Migrate Maven packages from Sonatype Nexus to GitHub Packages

This gist describes the process we've used to migrate our Maven package repository from Sonatype Nexus to GitHub Packages. The same process could be used for migrating any Maven package repo that is in the standard layout.

We created a special repository on GitHub to hold all of our Maven packages. You might decide to migrate packages to different repositories, in which case invoke the script multiple times.

The script uses find to look for all of the folders containing poms and upload them. You specify the folder
