First, the models that techies take for granted, others do not.
- A slowly refreshing web page over Remote Desktop suprised me not at all--a terminal server in city A is rendering graphics, and sending the images over the internet to the machine in city B to display, and the machines between them are paying to encrypt, then decrypt the traffic. But to the user--a very intelligent person--this simply meant that IE is slow.
- To connect to the internet from the event center's network, one must first go open a browser, which will present a log-in page. Ah, but if you open the browser to take you to a secure site (office email, for example), the browser will (rightly) warn you of a certificate mismatch. This is not really a problem, but it looks like one.
Third, cables, about the simplest bit of hardware there is, will let you down now and then. Twenty-five years ago, my problem was likely an RS-232 connector with a pin loose or out of place that would. In 2013, a couple of times it was an RJ-11 connector with a worn-out clip. Securing them with tape worked, but replacing them would have made me feel better.
