In this post I’m demonstrating how you could use Hashicorp’s Vault TOTP generator and an authenticator to connect to a dynamic ssh port. This is mostly a proof of concept and not a production grade solution, so use at your own risk.
What’s TOTP? It’s a Time-based One Time Password. TBOTP is probably too ugly of an acronym to have gained widespread use. I don’t know, I didn’t coin it.
¯\_(ツ)_/¯
While browsing my local thrift store, I stumbled upon a little gadget that I decided to repurpose:
Disney Infinity USB NFC Reader
It was only $6 USD, so I thought it would be a fun project.
I searched for ‘Disney Infinity Linux’ to see if any work had been done toward decoding it or making it work. I found various sources that suggested that Playstation or Wii versions work fine, but the X-Box version was challenging. Fortunately, among the 5 they had, one was the Wii/Playstation version so I bought it.
I’ve been exploring Thunderbolt quite a bit lately. As a follow up to my post about using Thunderbolt in a NAS, I recently bought a Gigabyte Maple Ridge Thunderbolt 4 add on card. I’ve captured a few thoughts, observations and pics here.
In this post I’m demonstrating how to create a high-speed macos volume using quantity 2 Thunderbolt ports and NVMe enclosures. This solution uses RAID-0 (striping) so the failure threshold is more than twice that of a normal standalone disk. This example is for demonstration purposes and could be useful for video editing scratch space, rendering, large photo sessions or similar uses. Obviously, good backups (RAID is not a backup) or a more reliable storage tier is recommended for daily use.
In this post I discuss how you can upgrade a NAS Server by adding Thunderbolt 3 for lightning fast connectivity at 20 or 40Gbps. This particular implementation is specific to an Apple Mac Mini M1 and a Linux NAS server on an older Supermicro X10SRL-F motherboard, but the principles should be the same on similar architectures and operating systems.
Pushover on macOS
At home I run a lot of gadgets. A mix of computer servers, IoT devices and various Raspberry Pi projects that I’ve built. I always want to be aware of what’s happening with the home, so I’ve been using a notification app called Pushover. It’s a nice notification utility that can send messages to your phone or tablet, in addition to your desktop browser. The keyword here is browser.
Watch local broadcast TV on Plex without an antenna.
Locast is a free service that receives over the air (OTA) broadcast television signals and encodes and legally distributes them digitally across the internet. Using the program locast2plex you can receive this digital content and send it to a Plex Media Server. Plex will allow you to record, time-shift and save this content. It works exactly like a Cablebox / DVR.
Grafana is a great tool for visualizing data. Grafana
In this tutorial I’ll be putting annotations, or comments on points of interest overlayed on top of graph panels.

DAS Architecture
Update: I’ve recently added a Thunderbolt 3 PCIe card for easy 40 Gbps connectivity.
There are a lot resources online for building your own DIY DAS. A lot of them contain good information but none of them were comprehensive for the DAS I wanted to build so I compiled the information that was useful for my specific 2019 build here. The prices linked below are subject to market fluctuations and timing, so some of the components I found at a great price. Overall they should be roughly the same as what you can find. Your mileage may vary.
