About Pat Gunn

ūüďĖ Summary

Unix Systems Wizard. Occasional Scientist. Mixed programming/systems/network admin skillset interested in solving hard problems that require deep and broad knowledge of Unix. I'm a systems programmer - I like writing software that composes or assists the operating system/cluster. Filesystems, databases, clustering software, VPNs, stuff like that. I also like refactoring code, writing APIs, and building language bindings. My curiosity and desire to keep learning sometimes takes me out of this focus. Check me out on Github - I sometimes teach classes: 1) Perl and Python (concurrently) 2) C 3) Unix - into, admin, internals 4) SQL Things I like: PostgreSQL, Ganeti, Perl, C, Java, Git, Refactoring, SQL, Linux, OpenBSD, FreeBSD, Solaris, glue between programming languages, Cisco, IPTables, VPNs, BIND, vimSite Reliability Engineer @ From December 2015 to Present (1 month) Greater New York City AreaSenior Systems Engineer @ This was primarily a systems administration role with moderate and varied programming. I was on the team responsible for hardware and software infrastructure (partly in AWS, partly in machine rooms). We had full responsibility for many systems (such as our Jira install) and OS-to-configuration-management responsibility for many other systems (Chef). I wrote a fair amount of code to handle scaling problems with available tools, debugged code, handled operational concerns, and liased with other teams while documenting and developing best practices. After hours I had side projects for other teams in the company, where I wrote a diagnostic tool for our support team and contributed code for one of our storage engines (WiredTiger) and assisted with competitive analysis documents relating to other databases I have expertise in. I also taught introductory Python programming classes for other employees.

I joined to improve scalability for the software stacks we were using on our servers, tuning the kernel and network stack and evaluating and writing userland software. Outside of this, I participated more broadly in systems administration: capacity planning, doing machine room work, and writing puppet recipes. I also wrote tools to parse and automatically diagnose error logs we received from client software. I brought a number of new technologies into the company.

Responsible for design and development of new software features (most notably addition of cross-site VPN features, improvements to event system) and extension of the emulab model for new kinds of clusters (large FPGAs+laptop, VPN-linked remote distributed systems on diverse/uncontrolled networks). Also responsible for local Emulab cluster and training grad students on its use for research. Managed technical aspects of the CMCL lab - purchase/configuration/maintenance of server hardware, systems administration of large numbers of machines, operating systems imaging, design of a new machine room, documentation.

I performed fMRI-based neuropsychology research for the ACT-R group, assisting with the design of experiments, writing software to generate stimuli and otherwise programming the experiment, recruited subjects and ran them through the experiments, and did analysis and presentation of the results. This research was published in peer-reviewed journals. I was also responsible for the cluster on which we performed the experiments, evaluating and maintaining software on those systems and training people in their use. During my tenure in this role, I built and moved those systems into a machine room. I also maintained our research group's website and performed all other development and systems tasks needed for the group unrelated to our cognitive modeling software.
