About Adam

I’m a programmer specializing in OS and Security, an astrophysics undergrad, and an occasional engineering manager. Currently, I work on AR/VR devices at Reality Labs. Previously, I did AI/ML & Cloud Security at Databricks, and before that I worked at Google on Linux Kernel Security and some related things, like eBPF LSMs and memory forensics.

I’m interested in OS security, security of ML and medium scale astrophysical simulations (like planetary formation).

Nothing expressed on this website reflects the views of any past or present employer or academic institution.

Some Interesting Open Source Work

• Pedro (Author): an LSM implementation in eBPF. Unlike other BPF-based security tools, this one is robust, because it uses the same framework as SELinux and AppArmor.
• Santa (Contributor):
  • FS Spool output mechanism (while at Google)
• Go (Contributor):
  • Minor Linux improvements, e.g. the original bitfield support and a syscall wrapper for perf.
• Linux (Contributor):
  • Fixing some selftests
• MacPmem (Author): a physical memory acquisition driver for Intel Macs.
• EFILTER (Author): an SQL query language for native Python types.

Other open source work is split up between two GitHub entities - my personal account and an organization named after this website. (Sorry.)

This Website

90% of this website is experiments, APIs, notes and demos only accessible to specific people. The remaining 10% is a handful of articles I thought were interesting enough to publish.

The Wow! Signal

The Wow! signal was received in the summer of 1977 and was, for a time, considered the strongest candidate for an extraterrestrial message in the history of radio. The attending astronomer, Jerry Ehman, wrote the word “Wow!” in the margins of the signal’s printout, giving it the moniker. The signal lasted 72 seconds, then fell silent and never repeated. Its origin remains unknown.
