  • Website Stability Woes

    Website Stability Woes

    This site has been offline for almost a day, and I hadn’t noticed! Luckily, I came here to draft a post about my recent experience with a PHP bug, and I noticed that the page was loading to a white screen. Experience teaches me that the web server Caddy likes to return empty responses when…

  • CrimeCon 2023 Day 3 Brief

    CrimeCon 2023 Day 3 Brief

    Today’s presentations were even more deeply moving. As a tagalong, I did not expect the majority of presenters to have a direct and personal stake in the crimes. I was also surprised that, despite the well-known shortcomings of our justice system, the victim’s families who were present generally felt positively towards the police. Generally, it…

  • Dimensions of Performance

    Here, I present a list and description of the performance dimensions that actually matter so far in my software engineering career. No flex, no marketing, no metrology.

We had a wonderful time! The only other convention that I’ve attended regularly…

  • PHP-FPM Small Site Configuration

    This topic has been addressed accross the Internet, but I’m deeply unsatisfied with how it’s addressed because the materials I see don’t directly answer my key questions. The manual doesn’t do a great job of explaining how to configure these parameters. This page explains the configuration descisions I made for this website. Background The server…

  • PHP is Pretty Bad

    I write about a fundamental security design weakness in PHP-based web applications, a gift that keeps giving despite our best attempts to contain the ghost of the past.

  • Initialization


    Wow! Setting up this site was a lot more involved than I expected, but I’m glad I made the ultimate decision to set up a server from scratch rather than subscribing to a shared hosting service. My main concern with using a plain VPS was that the setup would be trivially simple and result in…
