Traffic Question 14:

A traffic light turns yellow and you’re not quite going to make it through before it turns red... what do you do?

  1. Stomp on the gas pedal and zoom through
  2. Continue through the intersection without any change in speed
  3. Wait until the last second and then stomp on the brake
  4. Start coming to a gradual stop immediately
  5. None of the above

Moliner's Answer:

A. Stomp on the gas pedal

That way we will beat the “red” by a mile.

Conventional Answer

D. Start stopping immediately

This is the “safe” answer, so we’ll go with it.

I think stomping on the gas is really what people’s first instinct is. There are several things that don’t quite mesh if you think about them.

  • Yes, you will be going faster, but it takes too long to accelerate, so it doesn’t really make much difference. (You are likely saving less than 1 second; see image.)
  • Whatever speed you get up to... if it makes any real difference, you're likely to be significantly over the speed limit.
  • You are crossing several more sight lines, so it is that much more likely for a police officer to see you.
  • Is it really safe to go through an intersection at twice the speed limit?

Timer

The timer can count up from a time in the past or count down towards a time in the future.

The timer's appearance and the format of the time (and text) is very configurable. You can hide it's border, it's background, set the color and glow effects.

Sound Recorder

This is a simple recorder that records directly to an MP3 file. Recording can be paused and resumed.

The recording window has a compact mode and can be set to stay on top of other windows, so it can be out of the way, yet still visible.

When done recording, you can playback the recording or upload the file to an FTP site.

RocketDock with multiple bars\docks

Submitted by drew on

It seems there is plenty of interest about how to make RocketDock work with two or more docks or bars. Most answers say to use additional docking programs--one for each dock you want. Or use a commercial program that offers multiple docks. I think RocketDock is excellent except I want more than one. I finally figured out how to do it!
