  • False Positive

    Since a bit before my birthday this year, I have been uncertain where I left my notary seal. I have been trying to stay positive about the situation, but I must admit that I spent an unhealthy amount of time obsessing about its location and whether it has been used in my absence. The last […]

  • I took this picture

  • Trip Report: UW signing-party

    Dear Debian Users, I met last night with a friend from many years ago and a number of students of cryptography. I was disappointed to see the prevalence of black hat, anti-government hackers at the event. I was hoping that civilized humanity had come to agree that using cryptography for deception, harm to others and […]

  • A harowing upgrade

    I just dist-upgraded the blog server to jessie. A couple of errors from code with checks for which modules are enabled from .htaccess (deprecated and now obsolete behavior). Nothing all that rocky. Go team Debian!

  • MySQL Meet-up 20141208

    I had an enjoyable time last night at Twitter with local MySQL DBAs and developers. We had an attendee who has no experience with SQL or programming at all. She is interested in organizing her collection of recipes and had heard a rumor that MySQL was a good tool to use for this task. She […]

  • Happy Birthday to Collier Technologies LLC!

  • Configuring voice service on a Cisco 2801 Integrated Services Router via Asterisk

    So I’ve configured voice service a number of times, but never using Cisco equipment. There’s a business starting up here on Orcas Island and they need a number of lines voice and fax service. I had a spare 2801 router laying around and heard that it’s possible to provision voice service using these machines. So […]
