Recently, I gave my homelab a fresh upgrade by adding Lenovo ThinkCentre M910Q Tiny systems and a few P320s equipped with Nvidia Quadro P600 video cards. These systems are compact yet powerful, documented to support up to 32GB of RAM each—but with a bit of tweaking, they can handle an impressive 64GB! They might not be the most powerful setups […]
Octoprint container in Debian Windows WSL 2 and Docker Desktop
Here’s a list of steps to get octoprint to run within a container on Windows. I happen to have a windows system running next to my ender so instead of infinitely waiting for a raspberry pi I decided to run octoprint in a container within windows – if possible. Using Debian was a challenge, but I prefer it over Ubuntu, […]
Docker volume backup and restore the easy way.
I haven’t had to move docker volumes around in a few years, but I finally had the need today. As usual, I searched for the process, knowing that most examples are… well… not very good. Well, as I almost resorted to pulling a manual job using ubuntu, I found a great write-up by Jarek Lipski on Medium. Here’s how you […]

Take control – from the Center for Humane Technology
I couldn’t agree more about how to take control of your digital consumption from, “The Center for Humane Technology”. Here’s the link and a snippet from the web site: https://www.humanetech.com/take-control
The Social Dilemma
I thought I understood the general concepts and algorithms that companies like google, Facebook, twitter, etc. use but I was astounded about how much it impacts us as a society. The documentary, “The Social Dilemma”, on Netflix, is filled with conversations with many of the original architects of these systems and how monetization though ad targeting is driving behavior modification […]
So long, Facebook, and Thanks for all the Fish …
Good Morning!After not being active on Facebook for almost a year now I made the move to completely delete my account. While it was surprisingly tough initially it was a great decision. I realized all the ads and shaped content was not worth the family and friend connection I was actually seeking. My account on Instagram will probably be deleted […]
Password-less ssh in 2 Glorious Steps…
Local System – Let’s call it alphaRemote System we don’t want to have to enter passwords for,Let’s call it foxtrot Prep: Harden your existing ssh keys since RSA 1024 sucks.

HomeLab Build
Since I had a old windows laptop as a plex and file server for years I thought it would be good to try something new. After researching options I ddecided to try FreeNAS. Since it has ZFS and I’m an old Sun guy – why not. Well…. After a few weeks I decided to abandon FreeNAS and roll my own […]
Raspberry Pi backup using fsarchiver and other tricks
So I ran into a few issues using the dd image backup I referenced prior Raspberry Pi 3 SDCard backup The Image is very large even though the data was not. For example on a 32GB SD card I was getting a 12GB file. I only have 3GB of data! so that was a bummer. When it comes time to recover, […]

Living on a Raspberry Pi!
This feels a little weird! Playing with the overclocking and it really makes a difference! The settings below look stable but make the proc very hot (over 85 degrees c.) From /boot/config.txt: # Overclock settings – disabled until heat sink is added. 170327 SeanK #arm_freq=1350 #core_freq=500 #over_voltage=4 #disable_splash=1 ##force_turbo=1 #boot_delay=1 #sdram_freq=500 Also created a script to put the governor in […]

Netgear Stora NAS
Warning: Nerd Content ahead! Since I work helping companies manage their enterprise storage environment, I tend to be very anal with storing my data at home. It needs to be resilient, redundant, and fast. Why? I’m retarded. Most of the time, I spend more than enough money on something I have to manage and tweak constantly. No inexpensive NAS […]
Best way to tether your iPhone – PDAnet
Unlike most apps that will provide a proxy web service to your computer through your iPhone PDAnet will provide a complete network solution for tethering your computer. Basically, you can use your iPhone as a computer wifi device, without restriction. While proxy apps will work well for web applications, it doesn’t work for stuff like email, ftp, ssh, etc. PDAnet […]
Old fashion “Open Folder” Icon in the Dock
While the newer versions of OS X have been great and the dock has matured, I hated one thing. Sometimes I just want to put a directory on the dock without it doing it’s crazy effect stuff to it like Fan, Grid, List, etc. Many times all I want is a dock icon that will just open a directory in […]

Su.pr to shorten urls
I just started using su.pr to shorten long urls and it has the ability to do some very cool stuff if you link it into your wordpress site. I prefer it over tunyurl and others. Check it out!
Great Data Storage Presentation
If you go to http://dsstos.blogspot.com/ there’s an excellent presentation on data storage concepts and recommendations. It’s HDS AMS focused, but the majority of the presentation relates to general data storage. Great stuff!
Cleanup the Open with… menu in OS X
