I left my keyboard at work and I wanted to do some programming on the weekend. I'm going to drive into work and grab my keyboard.

In case you want to know how to configure IPv6 using CenturyLink's 6rd tunneling service. There are three files to update with my script: /etc/radvd.conf.header /etc/default/centurylink-6rd /etc/ppp/ip-up.d/centurylink-6rd There are a couple of environment variables in /etc/default/centurylink-6rd that you will want to set. Mine looks like this: LAN_IFACE="ens18,ens21,ens22" HEADER_FILE=/etc/radvd.conf.header The script will configure radvd to advertise v6 routes to a /64 of clients on each of the interfaces delimited by a comma in LAN_IFACE....

Hi friends! I haven't written in a while. I've been caught up in work. But between working, I've put together some new equipment in a couple of new racks. I bought an audio dampened 15U rack a couple of years ago or so, and into it I've placed the RAID array and an HP desktop form-factor ML110 server to drive the disks....

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 to distribute it over the LAG evenly. That's another problem for another day. I know it can handle six large streams at the same time, which is great.

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 old firewire port and some ASIC on board. [ 416 more words ]

A couple years ago, I bought a 12G SAS disk to see if I could get it to work with the RAID controller with external SFF-8088 ports that 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 optimistic about my ability to get things all set up. [ 1,083 more word ]

Hello folks! My team spent hours and hours beating our head against a Sonar deployment problem on Ubuntu Trusty (14.04 LTS). I thought I might share our findings so that you won't have to! As you probably know, Trusty only makes Java Development Kit 1.7 available on the stock installation. The current stable version of the Java is 1.8. The way we install this is to use the… [ 294 more words ]
