Mirrors Are Back Up - Sorta

My yum mirrors are back up and stable. Although they're 100% on my home infra atm. Long term I plan to use an OVH-Virgina set of VMs to act as caching proxies before hitting my home.

Tape Library: Why Tape?

While discussing my new tape library a friend asked "why tape?" 

The answer is pretty simple: 

  • LTO-6 is $7.58/TiB
  • 8TB HDs are $24.83/TiB

At the end if the day I can get tape for 1/3 the price of hard drives. While the upfront cost of tape is higher ($4500 for tape vs $1500 for disk), it becomes worth it pretty quick to me. 

Wifi For ARRL Field Day: LARG/K4LRG 2008

For LARG's Field Day 2018 I'll be setting up a wifi based network. It will be used for N1MM+ logging, restricted internet access, and remote radio control (ie Flex6500). To do that I'm using a set of up to 10 of Ubiquiti's UAP-AC-MESHs and six NanoStation Loco M5s. The UAP-AC-MESHs will handle most of the traffic while the NanoStations will provide any long distance links. Although given the site size I don't think anything but a UAP-AC-MESH per station will be needed. 

Ubiquiti POE

Found out something interesting today. My NanoStation Loco M5 (it's am XW version) will run on a little over 5v via POE. Dropping it just a hair below 5v would allow it to start but it couldn't run the wifi module. I suspect 5v may not be stable in the long run. That's a test for another day. 

My UAP-AC-MESH, which takes 24v/48v needed a full 24v to run. Even 16v wasn't enough. I didn't try anything in the 16v to 23v range.
