  • Have a f***ing sales person call me!

    No, I won’t return your cold-call if your job title is similar to any of these:

    • “Business Development”
    • “Growth Account Executive”
    • “Revenue Operations”

    Hang up the phone. Stop sending me email.

    Find someone with “sales” in their title. Have them call me. I’lll gladly respond.

  • Usenix LISA is no more. Here's my retrospective

    The Usenix LISA conference is no more. After 35 years, I have a lot of good (and some not good) memories of the conference. It was a big part of my career and I’m sad to see it go. However I’m proud of what LISA accomplished.

    I wrote my personal reflections on the conference in a new article published on the Usenix website. Warning: this article includes some over-sharing.

    Read it here: LISA made LISA obsolete (That’s a compliment!)

  • The Minimalist Headset Solution

    I got sick and tired video conferences being delayed by audio problems. I know that a lot of times it is a problem on my end, but I think everyone has had audio problems. How did I fix it? I got rid of any feature that caused me trouble until I had a trouble-free headset experience. Spoiler alert: I had to eliminate nearly all features. The purpose of this blog post is to provide links so that people can purchase the same equipment I now use.

    • Evading or leveraging macOS's DNS mucking

    • Refactoring a Loop That Was Trying Too Hard

      I fixed bug last night.

      The bug was difficult to fix because the code was so complex. I wasn’t really able to fix it until I simplified the code. Once the code was simplified the bug was easy to fix. While doing this I found an anti-pattern that I now call “One loop trying too hard”.

    • A developer's view of umask

      There are a zillion pages explaining how umask works from the user’s point of view, usually with great charts and tables explaining all the bits.

      However in all my years I’ve never seen umask explained from the developer’s point of view. What do you provide to creat()/open()/mkdir() (in C) or os.OpenFile/os.Mkdir/os.MkdirAll (in Go) so that the user’s umask is in control.

    • Go has eliminated most of my off-by-one errors except 0... I mean 1.

      Go’s range operator (for x = range foo) has eliminated the most common trap where I make off-by-one errors. The next largest category of off-by-one errors would be eliminated if there was a way to specify the last item in an array. It would also improve a developer’s ability to convey intent.
