respecting leaving computers on, or not
Please excuse my incorrect title.
"Always remember that computers are just glorified light bulbs - they rarely fail in continuous use and usually go pop when turned off and on."
Not entirely true. LEDs can be turned off and on millions of times per second with little fear of failure. Whereas, the filament of an incandescent bulb goes from room to temperature to 4500° in a split second. As with most materials, the light bulb filament will eventually deteriorate from temperature fatigue, and the frontal spike of switched on current can separate it.
Computers go from room temperature to approximately 80° see fairly gradually. Hence, temperature fatigue does not apply here. Furthermore, switching power supplies in modern computers utilize far less capacitance than the AC filter bridge networks applied in power supplies of yesteryear. Hence, frontal spikes are not of the same amplitude, resulting in a much lower risk of failure at startup. Hence, everyone needs to think of the power that's wasted by an idling computer that could better be used elsewhere.

Regardless of "the where" the general advice remains the same: Look at the link, and by that I mean the click-through text AND what the actual link for said text is.
If you've participated in the US Census and supplied them with your cell number as part of that, it could very well be legitimate. If the link indicates www.census.gov at the beginning it is almost certainly legitimate.
But, if you want to exercise the maximum caution, even if the link appears to be legitimate, don't activate it as presented. Go to your web browser and hand-type the link in, and see if that takes you where you'd expect it to.
In this case, if it starts with census.gov I have little reason to believe it's fake, but it's not impossible.
But the basic principle with suspect links is you never activate them directly.
