  • Rack coming together

    I now have four six-port Qotom systems and one four-port Qotom system in my rack. I have successfully verified that the newest of these is capable of pulling about 745Mbit/s of 1500-byte frames through the switch from six other hosts. I bet it will push data at the same rate. but I can’t get iperf […]

  • Recovering videos from DV tapes with Canon ZR80

    I am recovering some tapes from back in the day that some of you may enjoy. Here is a log of the process so that maybe you can recover some of your own DV tapes. Seems to work well in modern Debian. To attach to the camcorder, I used a PCI-e card that has an […]

  • The woes of 520-byte sectors

    A couple years ago, I bought a 12G/s SAS disk to see if I could get it to work with the RAID controller with external SFF-8088 ports which came with the system I got while I was working at The Linux Foundation. I got an enclosure to go with it because I was enthusiastic and […]

  • Some work on a VyOS image with Let’s Encrypt certs

    I put some packages together this weekend. It’s been a while since I’ve debuilt anything officially. libffi-platypus-perl libalien-base-perl libalien-ffi-perl libffi-checklib-perl libshell-config-generate-perl libshell-guess-perl The plan is to build a binding to the libgnutls.so.30 API. The certtool CSR (REQ) generation interface does not allow me to create a CRL with “not critical” attributes set on purposes. Maybe […]

  • 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 […]

  • I think I just accidentally the whole Seattle EDM scene

    It was unintentional, I promise. PS, what are you doing the night before Samhain this year? Feel like giving me and my bike a ride to Bellingham?

  • 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, […]
