Software

Github

Here's my github page.

Postgres

I have been contributing to Postgres for long enough that it's tiresome to maintain a list. But I'm especially proud of \ef in psql and PQprepare() in libpq. I also speeded up CRC computations in Postgres 9.5, first by using a faster algorithm and then by using specialised hardware instructions.

I wrote the Postgres protocol dissector for Ethereal (now Wireshark).

Ansible

I use Ansible at work, and have contributed extensively to the 2.0 release, ranging from typo fixes, to vault improvements, to a complete rewrite of the inventory and hostname parsers, and a rewrite of the SSH connection plugin. I've also written about Ansible.

Archiveopteryx

Arnt Gulbrandsen and I wrote Archiveopteryx, an open-source mail archive server. (The company we founded to develop it, Oryx Mail Systems GmbH, no longer exists, but we still maintain the software in our spare time.)

Other programs

• tappet is an encrypted VPN that uses NaCl. (source)
• heaping pings many hosts every few seconds, for monitoring. (source)
• gmail-mirror reliably downloads mail from GMail using IMAP. (source)
• snippets is a jabber bot that asks you what you're doing. (source)
• pemtrans converts an OpenSSL RSA key to a cryptlib keyset. (source)
• A small managesieve client to talk to the server in Archiveopteryx.
• Inspector34 records and replays HTTP requests. (source)

I'm one of the maintainers of Mojolicious, and I wrote an application framework named Gadwall based on it, for my own use. Here's a list of my other CPAN modules.

(I've removed links to programs I no longer maintain, and there were many things on my old web site that are not here. I'm sorry, I didn't think they were worth reproducing.)
