A prompt injection doesn’t have to act to be dangerous. It can hide, copy itself, and spread agent to agent. Why AI security is an epidemiology problem, and how to respond.

MCP-Airlock Is Now Trentina: The 1377 Quarantine That Inspired Our Rename
MCP-Airlock is becoming Trentina — named after the 1377 quarantine system from Ragusa that inspired its architecture. Same three-layer defense, same gateway, better name.

MCP-Airlock: An Open Source Defense Against Prompt Injection in AI Agents
Update (June 2026): MCP-Airlock has been renamed to Trentina. The project has grown from a web content sanitizer into a full MCP gateway with per-consumer profiles, tool allowlists, and parameter-level access controls. The new name reflects that expanded scope — and avoids a naming collision with another MCP gateway project. The architecture described in this

RHEL, Glusterfs, and the FUSE Client
This presentation overviews RHEL, Glusterfs, and the FUSE client. It was created for the Akron Linux User Group in May. There was a quick presentation followed by a demonstration using four virtual machines running RHEL 6.2. Three of the virtual machines were used as a Glusterfs storage pool using the open source RPMs. The fourth virtual machine was used to mount the storage pool using the FUSE client. I demonstrated the resilience of Glusterfs by pausing one of the Glusterfs storage pool nodes while the client was still connected. Since a distributed/replicated Glusterfs volume was used, the client paused for a short amount of time, then showed a listing of a directory with 1000 files in it. This was all done while the mount command on the client node showed the paused Glusterfs node being mounted, magical…
Designing a Robust Monitoring System
This presentation was created for the Pittsburgh Perl Workshop 2011. It gives an overview of a fairly sophisticated set of criteria to build a large Nagios installation.

Log Analysis with Python
Abstract This presentation was created for the PyOhio 2010 conference. It gives an overview of Artificial Ignorance, command line graphing, and word counts with petit. It also gives a quick examples of weekly and monthly reporting when dealing with a syslog server which records switch, router, firewall, and server logs. Presentation
