Some of the greatest inventions solve problems you didn’t realize you had. While you’ve probably been getting along just fine without these nifty little devices, you might just love them anyway.

Now that we know these exist, we might have to do a little shopping ourselves!

Nest Thermostat:

Yes, it’s a bit pricey at $250, but it may end up saving you more than that over a year. Nest is a “smart” thermostat that can program itself based on your daily patterns and preferences.

It’s summer, and while we’re busy trying to stay cool, it’s important to remember that our laptops need climate control as well.

Keep these tips in mind for the long, hot days ahead:

Don’t leave your laptop in the car. Metal components can expand in the heat, and plastic ones can melt. If you must leave it, make sure it’s completely powered off (not just “sleeping”) and store it underneath a seat, out of direct sunlight.

Keep air circulating. Make sure there’s a way for heat to dissipate from the machine, particularly from the bottom. Don’t use your laptop while it’s sitting on a bed or a blanket; not only will this prevent air from flowing, but it will insulate the generated heat.

This week, the Washington Post reported that a computer had finally passed the Turing Test.

While many other publications quickly pointed out that this was probably not correct, it sparked a jump in searches on what the Turing Test is.

So… what is it?

In 1950, computer scientist Alan Turing proposed the question, “Can machines think?” As this question was deemed too difficult to answer (how do you define “think?”), a new, solvable problem was proposed: can a machine trick someone into thinking it’s a human?
