Spring 2015 MP Credit

This semester I took 2 credits of MP351. I also took 1 credit of Directed Study with Professor Searleman.

This semester, I was a lab director and lead the Core Maintainers group.

I assisted in the setup (software and hardware) of:

• lapras - Secure domain administration, running FreeIPA on Fedora. SuperMicro server.
• metapod - Lab storage, running a ZFS pool on FreeBSD. Domain member. SuperMicro server.
• eevee - Virtual machine host, running qemu/lvm on Fedora. SuperMicro server.
• mordor(?) - Network firewall, running Fedora. (in progress).

I also worked on several projects, specifically:

• My dotfiles
• flush - A simple shell that avoids using libc entirely (good reference for how to do this).
• Rust - My contributions to the Rust programming language. Worked with Corey Richardson (cmr).
• gl-rs - My contributions to the gl-rs project, an OpenGL binding generator for Rust.
• 7hrl - My Seven Hour Roguelike project.
• sdat2img - My contribution to the sdat2img tool, which converts new-format Android diff update images to standard, mountable disk images.
• cathode - Cathode, the Rust operating system. Currently boots, with EFI. Worked with Colin Davidson and Graham Northrup.

For my directed study credit, I worked with Professor Searleman on the labs for CS241. This entailed the set up of psyduck, a virtual machine, and setting up Fedora, SELinux, and the webserver to run the code for the labs in the class. Additionally, I worked to modify these scripts to work better in our environment. The bomb lab was modified to speak SMTP, rather than calling out to a (potentially unavailable) sendmail. Several bugs were fixed in the automated grader for the buffer lab. With the release of the new book and new course/lab material, I wrote documentation for future instructors in the processes and procedures used in setting up the newest version of the lab software.
