As an open source enthusiast, I have authored and maintain a few projects of my own. You can get details on the majority of these by visiting my GitHub profile and my OpenHub profile. The following is just a sneak peek of the projects I started:
Boost.Process: A flexible framework for the C++ programming language to execute programs and manage their corresponding processes. This was a project developed under the Google Summer of Code 2006 program and was later picked up by another developer who maintains it to this day.
etcutils: Standalone utilities to manipulate some of the configuration files in
/etcin a programmatic manner. Designed to be integrated into packaging systems as a lightweight dependency.
Kyua: A testing framework for infrastructure software. This is my star project and the one where I spend most of my (very little) free time in. Kyua is used, mostly, by FreeBSD to run its operating system-wide test suite. Kyua’s parent project, ATF, was developed under the Google Summer of Code 2007 program.
Lutok: A lightweight C++ API library for the Lua programming language. Lutok provides thin C++ wrappers around the Lua C API and makes extensive use of RAII to prevent resource leakage, exposes C++-friendly native data types, and reports errors via C++ exceptions. Originally developed as part of Kyua but split into its own project due to popular demand.
Markdown2Social: Converts simple Markdown documents to Google+ posts. Written in Python.
Nudgy Timer: Time tracker for Android that subtly pokes you every few minutes to help you figure out where your precious time is going to. Written in Java.
pkg_comp and sandboxctl: A couple of utilities to automatically build pkgsrc binary packages from source in a chroot-based sandbox. pkg_comp orchestrates the build using the pbulk build system and sandboxctl implements the management of the chroot-based sandbox on a bunch of different operating systems.
Shell Toolkit (shtk): Application toolkit for programmers writing POSIX-compliant shell scripts. This is a simple collection of shell functions to simplify the implementation of user-friendly command-line utilities.
sandboxfs: A virtual file system for sandboxing. This file system exposes an arbitrary view of the host’s file system under the mount point, allowing the fast creation of directory trees to back sandboxes and containers. Written in Go and owned by the Bazel project.
sourcachefs: Persistent, read-only, FUSE-based caching file system. This file system offers a mechanism to cache the contents of remote file systems transparently. Note that this was my first real Go program and hasn’t received a lot of maintenance since its publication so it may not be in the greatest style, but I wanted to publish it anyway. See Analysis of SSHFS performance for large builds for the motivation behind this project.
sysbuild and sysupgrade: A couple of utilities to build NetBSD from source and to upgrade a running NetBSD system. I hate executing procedures that involve more than one step by hand, so I have to automate them. These two tools are just two of many examples.
tmpfs: An efficient memory file-system, originally for NetBSD (2005) and later ported to FreeBSD (2008). This was a project developed under the Google Summer of Code 2005 program.
XML Catalog Manager (xmlcatmgr): A small utility manipulate SGML and XML catalogs. Designed to be integrated into packaging systems as a lightweight dependency.
Contributions to existing projects
I have also contributed significantly to the following projects:
Bazel: A fast and correct build system, originated at Google. I started working on this project as my main work assignment on January 2016 and currently focus on making this work on macOS as well as it does on Linux.
Colloquy: An IRC client for Mac OS X. Back when I decided to fully switch to this operating system for my desktop machine, I was connecting to NetBSD’s chat network, which uses the ICB protocol. In order to have a “pure” OS X experience, I added ICB support to Colloquy and along the way learned the basics of Objective C and Xcode.
FreeBSD: General-purpose Unix-like, free, open source operating system with a focus on performance and usability. I have been a committer since 2013. My work has focused on the implementation of The FreeBSD Test Suite.
Gnome: Desktop environment for Unix-like systems. I originally ported Gnome 2.x to the NetBSD operating system and was the sole maintainer of the resulting packages for a few years. As a result of this, I contributed countless patches upstream to address portability issues.
NetBSD: General-purpose Unix-like, free, open source operating system with a focus on correct design and portability. I have been a committer since 2002 and served as a board member for two years. Most of my work has been on pkgsrc, the NetBSD’s packaging system, but I have also laid the foundations of the NetBSD test suite and have developed the tmpfs file system.
