Troubleshooting a Ruby production application

Debug logging mode ON

I am by no means a Ruby expert, but I have been tasked with troubleshooting an existing Ruby application. Specifically some end user DB tasks were failing to save records and the application was throwing a generic error message to the user. By enabling debug logging and viewing the Ruby log file, I was able to see that the application was failing when attempting to send an email confirmation, then it would roll back all the DB changes since the overall

JPS300V 5V DC power supplies for LED signs

JPS300V is user selectable between 110V AC and 220V AC

The JPS300V DC power is a robust option for powering LED signs and other products that require relatively high amperage 5V output. 60A at 5V = 300 watts which is pretty hefty for a DC power supply. Out of approximately 80 PSUs, we have had around 2-3 fail. This is a roughly 3.8% failure rate in some fairly difficult situations (withstanding fairly intense heat, cold and moisture). Overall I would rate them as a good low-cost option especially if you can

Crossroads Inn and Suites, Salem MO WiFi review [EXCELLENT]

WiFi speedtest results, EXCELLENT

I regularly stay throughout Missouri for business. I normally test the speeds at every hotel I stay in. Recently I stayed at the Crossroads Inn and Suites in Salem MO. I have stayed there before, but they recently upgraded their internet so I wanted to run speed tests again. Here are the speedtest results: ~60.0Mbps D/L* ~12Mbps U/L* *average of multiple tests throughout stay.  These are some of the best speeds I have encountered.

Disable Skype Voicemail

Skype voicemail disabled!

I do not care for Skype’s voicemail feature. I much prefer Google Voice or other similar services. Oddly, I have been unable to find a way to disable the voicemail via the Skype app for Android. However, if you login to the Skype.com site you can disable voicemail at the following page: https://secure.skype.com/account?page=voicemail Woot! PS here are a couple screenshots showing voicemail enabled and then DISABLED:
