This paper describes the first work done towards my PhD. In it, I show that out of band data avilable via Redfish may be sufficient to perform classification on HPC workloads – in real time. This has important applications in security – specifically around detecting malicious workloads and misuse of HPC systems.

I presented the paper at the HPCMASPA Workshop at IEEE Cluster 2022. The slides I used are avilable as odp, pptx, or pdf.

Code is available on GitHub.

I gave a talk at A New HOPE on the privacy and security of hCaptcha, a commercial captcha product. This talk was officially called “hCaptcha: Profits over People and Fscking Useless”. Due to new information I got after the deadline for changes, the talk I actually gave I titled “Is the CAPTCHA dead?”.

The slides, relevant video, FAQs and other materials are online on a dedicated page.

This paper discusses the details of hardware discovery and maintenance workflows in Cray’s Shasta Systems Management software. It was written in my role as a Cray employee and represents the state of the system at that time.

Presented at CUG 2019 in Montréal.

Part of my work for Thaw America was proving that it was possible to extract Post Cut-Through Dialing Digits (PCTDD) from phone calls without extracting other dialing. In short, to tell a phone number from not-a-phone-number.

This patent outlines the method I created for to do that.

This paper outlines CCAD, a system for differentiating dialed telephone numbers from other dialed numbers (eg: credit ard numbers, PINs, passwords, bank account numbers). It is a writeup of the work I did for Thaw America.

A talk on FISCR 16-01, surveillance, and the consequences of allowing law enforcement to go looking through phone calls on national security grounds. Given in my role as part of Thaw America.

Presented October 22, 2017 at Radical Networks.

Slides in ODP format. These slides likely have accessibility issues due to unlabeled images. The speaker’s notes contain the important components of the talk and important images are described in the video. All other images are stock/filler.

Mike Walsh and I took part in a panel on surveillance at PirateCon 2017, the annual gathering of the Massachusetts Pirate Party. We talked about our work for ThawAmerica on the FISCR 16-01 decision.

I gave a talk to JHUACM about version control systems and the basics of use. Unfortunately, it was not recorded, but the slides are available.
