Reversing iLap, hacking IR protocols, and the creation of CoreIR
Reversing iLap, hacking IR protocols, and the creation of CoreIR My adventure into IR protocols, arduino hardware, and C++ all started when I found out that iLap was selling a small device. This small device, a $40 ‘timing gate transponder’ in essence quickly repeatedly sent a 7 digit number out of an infrared LED to a receiver at the finish…
Quick Dell n1524p thermal testing
Did some quick thermal/environment testing on the new Dell n1524p today… it survived quite well. The max physical (ambient) temp reached was 150F and the switch continued to operate normally. It did throw a few temp warnings in the logs and flag its status from “good” to “medium” but was not severely hindered. This test was run the old…

After reading several pages including this great writeup on improving windows storage spaces speeds, I found myself needing to add some SSD journal drives after the fact (after the spaces had already been created). For anyone else looking to do the same, here’s the powershell commands needed to do so. 1. Get the ‘friendly name’ of the disks you’ll be…
A lesson in backup testing!
This is a real world example of why you should always test your backups. Approximately two weeks ago while running a backup restore test an error started occurring that would cause all restores of the fileserver drive to fail, going back any length of time. A ticket was opened with Veeam support about the error and troubleshooting began later that…
