Get Free Wi-Fi By Sitting Near Airport Lounges

Antrikshy sneaks in a bit of free internet time at the airport:

When traveling, sometimes you might come across airports that do not provide free Wi-Fi services. But you can sit near airline lounges. They usually have free Wi-Fi and they are often times unsecured and leaking out into the public space.


Make sure you're staying safe on those public Wi-Fi networks!




Avoid Hard Brakes at Traffic Lights by Watching the Pedestrian Lights

Xagest keeps intersections safe by judging when traffic lights will change:

Traffic cameras at intersections are becoming more common in some areas, some people get a bit nervous whenever they drive up to a traffic light. I've noticed that a lot of people break hard as soon as the yellow light comes up, and that can get pretty dangerous (and not very good for your car). If you want to have some idea of how much time you have before that green light turns yellow, then red, take a glance at the Walk/Don't Walk light. A lot of them have timers now, and they'll let you know how much longer it'll take before the light turns yellow. Even if it's just the blinking hand, at least you'll know that you have a bit of time before the light changes.


Open Car Windows with the Key Fob

Jsertic helps us cool off our cars before we get inside:

I thought this was common knowledge, but I recently came across some persons who did not know the following: On newer car models, if you keep the unlock button on your remote pressed for a few seconds, the windows of your car will automatically open. This is really nice on a hot day, as I can open my windows from 50 meters away and the interior of the car will have cooled down enough to drive away at once. Same goes for the lock button, which will of course close any open windows, which is nice if you see that you forgot to close a window while leaving, as you don't have to unlock the car, get in, put the key in the ignition, close the window...


This doesn't work on every car, but certain car companies (like BMW and Lexus) do have this enabled.
