If you have Mellanox ConnectX-3 or ConnectX-4 NICs in your servers, I discovered it’s possible to do IPv6 OS installations via PXE. FlexBoot is their on-board PXE implementation that ships on their NICs and it’s based on iPXE. It turns out that as of FlexBoot version 3.4.718 from January 2016 they’ve added beta IPv6 support. […]

I wanted a new Avoton motherboard for my OpenIndiana home NAS with lots of on-board SATA so I could use the PCIe slot for a 10-gigabit NIC. I needed seven SATA ports, six for the data disks and one for the OS drive. The standard mini-ITX configuration seems to max out at six, and I […]

The Anaconda 19 (now v21) installer in RHEL 7 / CentOS 7 is a great improvement over Anaconda 13 that was used in CentOS 6. Among other fixes it was completely overhauled along the way.

It turns out because the UniFi controller software ships out of the box with a self-signed SSL/TLS cert that’s untrusted, Chrome does a smart thing and won’t prompt you to save the password for the […]

My old dedicated server is quite old and ass slow. I finally got around to moving my website elsewhere running Nginx+HHVM, and now it’s tolerable once again! I can finally enforce 100% https without killing the CPU.

June was such an exciting month and the good news over summer keeps getting better: People finally wise up and take down the Confederate flag (the “rebel flag” where I grew up) The US Supreme Court allows gay marriage (whether or not they hijacked diplomacy is another thing) ESA’s Philae comet lander makes contact with Rosetta […]

I love books. These days I buy most of my books for Kindle, but I still buy paper for books I really like and want to keep around. Tech books are notorious for being obsolete a couple of years after printing, but there are still several timeless books I use for reference and would recommend […]

In honor of xkcd 979, I’m posting this so future generations of Courier-IMAP users won’t have to Bing for a solution in vain (and hit lots of useless advice). In the process of finally getting around to upgrading my 2008-era courier-imap 4.1.1 setup to the shiny new 4.15 hotness and putting things in Chef templates, […]

I finally reached a critical mass of various plants, flowers, and succulents on my apartment balcony that required multiple trips to the sink when I needed to water them. While browsing the hardware store I was eyeing the garden drip irrigation systems and thought why not? Originally I wanted to use some sort of a […]
