  • 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…

  • 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…

  • Relatively high sustained rates detected along I-405

    $ scp moonunit.colliertech.org:/mnt/downloads/sh1-disk-20140420T070034.xz . cjac@moonunit.colliertech.org’s password: sh1-disk-20140420T070034.xz 76% 534MB 11.1MB/s 00:14 ETA Come on little internet! You can do it! You can push 100Mbit! I remember when this was the fastest I could send data across my LAN. Not bad for a 20 mile shot up I-405. Sorry if I caused any congestion there, folks.…

  • UW Hypervisor looks stable

    UW Hypervisor looks stable

    The new hardware looks like it’s reliable. The one I swapped out 10 days ago crashed every 3 days or so for reasons I couldn’t discern. I changed that one for a spare I had laying around and have been hosting my blog on the machine to exercise it. So far, no crashes, and a…

  • Migrating VMs from pure paravirt hypervisor to hvm-capable hypervisor

    I’m also changing all of my disk layouts from being block devices per each guest partition to one block device hypervisor side per each /dev/xvd* guest side. The block devices all live on a single storage server and are being served via iSCSI. One of the guests is making use of AoE, but I’m thinking…

  • Replaced hypervisor

    The system which was hosting this blog had a tendency to go down every few days. I swapped it out for a spare yesterday. Let’s see if it stays up. The hypervisor hosts this web server, a mysql server and an SKS pool member, all of which are built on top of Squeeze.

It turns out that it was trying…
