I work for the Naval Research Lab doing research and development on Tor, and sometimes the Internet in general.

Projects

In general, you can find code I write in public on GitHub and on my Gitea server.

Simple Bandwidth Scanner

Project link

Some of the Tor directory authorities run bandwidth scanners to measure the bandwidth of relays and include their measurements in their network status votes. Clients use the consensus of these weights to inform their path selection process with the hope that every circuit they build will have roughly equal performance, regardless of the relays chosen. This achieves a form of load balancing.

Historically, the directory authorities that ran bandwidth scanners (bandwidth authorities), ran torflow. Time passed, it slowly become less maintained, and the collective knowledge of how it worked slipped away.

Simple Bandwidth Scanner (sbws) aims to be a quick to implement, easy to maintain replacement for torflow.

KIST

KIST is a new scheduler for Tor. It is merged into Tor code as of 0.3.2.9. It prioritizes low-bandwidth, bursty traffic (web traffic) over high-bandwidth, continuous traffic. See my relevant publications for more information.

BM - Blog Maker

Project link

BM is barely maintained.

This blog-like website is created with bm.

BM is a set of scripts that use common GNU utilities to dynamically create a static blog. See the README at the project page linked above for more information.

Services

I have managed 10s of Tor relays over the years, many of them exit relays. Right now the current number is ~4, most are exits. I don't list them here simply because the list would end up being out of date for an embarrassingly long time.

I host a Gitea instance at http://m6su7s3ir7dxggwg.onion (or the v3 onion)

I host a Robohash instance at http://5rqvahiexxwm4p6m.onion (or the v3 onion)

I run an IRC bouncer for members of the Tor Project.
