Biography

Josh Triplett is a PhD student at Portland State University and a Free and Open Source Software hacker. Josh is involved in research on relativistic programming and advanced synchronization techniques for highly parallel systems. Josh builds and launches Linux-powered rockets with the Portland State Aerospace Society, and hacks on numerous other projects . Lately, Josh does a lot of his hacking in Haskell.

* Composing Software Systems

If you can't reproduce your work reliably then you can't maintain it. You may get by for a while with ad-hoc build/release/deployment processes, but sooner or later they'll bite you. We'll present a new practical approach to assembling both software products and installed systems, drawing inspiration from sources including the functional programming community, commercial software projects, large IT deployments, and Linux distributions like Debian.

* Serialist: lazy web-crawling in Haskell

Serialist (http://serialist.net/) provides a way to find, track and read serialized content (e.g., web comics). It's implemented entirely in Haskell and demonstrates functional web application development, crawling, scraping and distributed architecture. Serialist uses interesting graph algorithms to add and step through content lazily.

* Unlikely tools for pair programming

Co-conspirators Jamey Sharp and Josh Triplett get up to a lot of miscellaneous hacking mischief together. Much of this hacking occurs while staring at the same screen, and tag-teaming the keyboard. Sometimes this happens with the two of them in different places. We'll demo our favorite tools and invite audience contributions to the discussion.

* On predicting predictors: hacking archive formats for fun and prophecy

We aim to inform you about the archive formats you use every day. We will include an in-depth look at the tar, ar, cpio, gzip, bzip2, and deb formats, as well as the internals of the Git object store. Armed with this information, we will show you a practical application: removing the redundancy between files in version control and distributions of source and binaries.

* Socket handoff: Concurrent fd sharing for performance and innovation

When different components want to use a shared resource in different ways--such as when they're implemented in different programming languages, or have APIs that aren't trivially compatible--the result is an API design challenge. X desktops today have both Xlib and XCB competing for access to the same network socket, and we needed a design that would let them share. We'll present this design, how we arrived at it, and why it's even more useful than we guessed.
