Hacking the Uppel/Sunchip CX-R8

As part of my job at Chef, I’m responsible for getting Chef on strange platforms. At the 2015 Chef Seattle Community Summit, I discovered that the community has a lot of interest in getting Chef on strange platforms as well. I was helping a community member get Chef running on an ARMv8 (also known as AArch64 or ARM64 depending on your platform or compiler), but I needed an inexpensive platform to put in the forthcoming community builds CI.

Goodbye, OpenStack

I just removed myself from every OpenStack mailing list and meetup. I’m sure I’ll still use it, but I don’t see myself as part of that community any longer. When I was at DreamHost, I really felt like part of that community and that I could help make it better. However, in the three years since I’ve left DreamHost, I have made zero impact and I’m tired of pouring effort into a community that is primarily Buisness Development/Lead Generation, followed by ecosystem echo chamber development, and thus getting nothing out of it.

I don't think VR is going to be a flop, a rebuttal to RPS

Rock Paper Shotgun, I love you guys. That said, I wanted to write a rebuttal to your recent Editorial entitled “Why VR is going to be an enormous flop” because I don’t think your giving VR a fair chance. Let me start out by saying I am an Oculus Kickstarter Backer, and I own the original Oculus Developer Kit, and the DK2. Let me also say that recent announcements from Oculus have made me really upset.

I thought I knew pain, and then I tried to switch to native IPv6 at home

For years, I have been happily using a Hurricane Electric IPv6 tunnel for my IPv6 at home. I have had it on five different ISPs and it has “just worked” (with the notable exception of U-Verse[1]) for 5+ years. However, my tunnel terminated in LA, and latency has been an issue of recent. I don’t blame HE, I picked where the tunnel terminated and I live in Austin TX now.

On spinning rust

It’s that time again, Backblaze has released another report on what’s the best/worst drive. The information is interesting, but I have problems with the widespread “conclusions” and some of the statements made on value. Having worked in several large deployments of hard drives I have a major rebuttal to every Backblaze report: You should not buy the cheapest hard drives possible for use in a Data Center. It’s that simple.

SSL Labs A+ Certification for Apache 2.4

After gaining some insight from Seth Vargo’s excellent post on doing the same things with nginx, I decided to tweak my Apache 2.4 config to get the same results: At first, I got everything but the TLS_FALLBACK_SCSV support. I did some digging and discovered that I had missed and OpenSSL update. Applying that and then restarting apache did the trick. Here are the relevant security announcements with the required versions of OpenSSL for ubuntu, debian, and RHEL/CentOS.

OpenStack != Free VMware

Last week was the OpenStack Juno Design Summit in Atlanta Georgia. I spent a lot of time in the Operations track, and there was a recurring theme: “OpenStack needs more enterprise features”. OKay, fair enough. But what features? “Integration into enterprise authentication?” Sure, we do that now with SAML2 in Keystone. “HA of OpenStack services” Also, available now. Two different methods even! You can run active/passive with corosync, or (my preferred way) run mutliple instances behind a highly-available load balancer.

Beginning of the end

Atlantis departed this rock for the final time today, and I was somewhat surprised that it did. On the one hand I knew this was a big deal for NASA that the final mission go off without a hitch, but with bad weather looming I was surprised the safety paranoia didn’t take over. While I am sad that the shuttle program is ending, I’m not as optimistic as Phil Plait that this isn’t the end.

Building an IPv6 Firewall

As As will gladly tell you, we are rapidly running out of unique IP addresses on the Internet. The good news is we solved this problem in 1998. The bad news is that, after more than ten years, we still haven’t widely implemented the new standard: IPv6. All of the big carriers support it, but getting access to the IPv6 Internet is still very tough. If you are a Comcast customer it is possible to get IPv6 access, and there are a few others who allow access as well.
