  • Notes on Updating Centos7 to 4.3.3

    Upgrades! Sometimes they are a lot of homework. Enabled Centos-Plus repos and elrepo for recent kernels. I figured out I want to install kernel-ml, kernel-ml-headers, kernel-ml-devel. That last one escaped me but is necessary because you need it when you do a dkms install. So after updating that stuff, I was able to dkms install…

  • Thot on Linux Video Editing

    The other night I ran thru what might be the gamut of video editors because kdenlive was crashing on me. I’m going to run down this list. Openshot: am finding it doesn’t import clips and align tracks to base audio comfortably. Did not like having to right-click-properties for fade-in, fade-out this and thats. Pitivi: gave…

  • Ubuntu 15.10, ZFS 0.6.5.3…Fragile

    Quick update on using a more recent version of zfs: very glad I set up a user who’s home directory is not /home, because if zfs doesn’t finish a scan, no /home attempting to install zfsnap, simplesnapshot, things that depend on zfsutils…all mess with kernel module this was much easier back when there were less…

  • Not My Favorite Xmas Card

    I’ve been listening to a lot of WTR and other podcasts that interview people who dwell on the topics of inclusion and empathy in the technical work space. I listen to them because I want other people around me to succeed. I want my sons and daughters to feel welcomed to the sciences or computer…

  • Ubuntu 15.10 and ZFS

    Some quick thots on doing this for my workstation: I have six 2TB drives in raid 10 zfs pool, and they would not import to 15.10 because 15.10 ships with (or tries to) zfs 0.6.4.2 I decided on /boot, swap, /, mdadm partitions for OS install needed to do 15.10 server cmdline install for mdadm…

  • Crazy Times with zxfer

    I’ve started using zxfer that @AllanJude referred me to recently. It does a nice job. My main difficulty was how to get it to work efficiently over the 10Mbps that’s my effective DSL speed. First, I made a copy of zxfer (zmxfer) that incorporates mbuffer. This is a crude hack, but helps me ensure that…
