Mainline Linux 4.4 kernel on a Jetson TK1

I was really hoping this would be easier than it was. Most (all?) of the pieces needed are upstream, with a minor patch for das U-boot needed to make it all work with L4T. I’m going to provide links to my u-boot images and kernel packages, but first I wanted to go over what I’ve done and why. My Jetson TK1 still has L4T installed on the internal eMMC device.

The very overdue ARM update

Lots to get to, so I’ll just jump right in: Uppel CX-R8 I gave up on this device a bit too soon it seems. Someone found these blog posts and reached out about rooting a CX-R8. While I wasn’t able to help him much, he helped me greatly by providing links to a TWRP recovery image which makes it super simple to install a SuperSU file to the system allowing root access.

The Arcade Project

I love arcade games. Some of my favorites are S.T.U.N. Runner, Teenage Mutant Ninja Turtles, Sinistar, and Tempest. I like the fighting games like Street Fighter, King of Fighters, Mortal Kombat, etc but are not very good at them. Ten years ago, I worked for a video game company and my “boss” also very much liked Arcade games. So he brought is personal collection about 30 of them in to work and littered them about the office.

Hacking the Uppel/Sunchip CX-R8, Rikomagic MK68, and Tegra Jetson TK1

Long overdue follow-up from my previous post. Let me dive in by topic: Uppel/Sunchip CX-R8 After a lot of roadblocks, I’ve given up on this particular platform. The primary reason for this was getting the MK68 boxes and being able to compare the two. The CX-R8 is pretty hacker un-friendly. The bootloader does some form of signing the boot, recovery, and kernel images. All of the existing Rockchip tools I could find to make these images say the ones from the device have bad checksums, and the images it creates the device reports as having bad checksums.

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.
