  • Regarding fdupes

    Dear readers, There is a very useful tool for finding and merging shared permanent storage, and its name is fdupes. There was a terrible occurrence in the software after version 1.51, however. They removed the -L argument because too many people were complaining about lost data. It sounds like user error to me, and so […]

  • Some statistics from the router at the cabin

    sip0 is a GRE tunnel between the router and the colo box in Seattle, the payload of which is encapsulated as ipsec traffic before being transmitted over the Ubiquity equipment to the switch that the CenturyLink DSL modem attaches to. I don’t get centurylink easter eggs in my search results when I use this interface. […]

  • Microsoft ACS announcement

    So it seems that Microsoft has developed an embedded device OS distribution called ACS and that this OS is based on the Linux kernel. http://azure.microsoft.com/en-us/blog/tag/azure-cloud-switch/ That’s kind of neat.  They’ve been consuming Linux for quite some time.  It’s nice to see that they’re producing some, too.  Thank you for being productive members of this community, […]

  • 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 […]

  • 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 […]

  • I just realized how old these name servers are

    I guess I’ve had them around for a while… Maybe I should clean these up… cjac@ns1:~$ ls /lib/modules/ 2.6.18-4-xen-amd64colliertech.fw+0 2.6.32-5-amd64 2.6.24-19-xen 3.2.0-4-amd64 cjac@ns2:~$ ls /lib/modules/ 2.6.18-4-xen-amd64colliertech.fw+0 2.6.24-19-xen 2.6.32-5-amd64 cjac@ns2:~$ sudo rsync -aue ssh ns1:/lib/modules/`uname -r` /lib/modules I remember editing the .config file for that kernel and building it on my first ever 64-bit system back […]
