Traffic Quiz 6: Is it possible to back out of a driveway and use only one lane?

Traffic Question 6:

The blue dots indicate the path used to pull IN the driveway.

Is it possible to back out of a driveway and head in the direction indicated by the pink arrow, using only one lane of the road?

A. No, one lane is not enough room.

B. Yes, it can be done in one lane.

Moliner’s Answer :

A. No

The laws of physics and geometry are different when you are in reverse. It is impossible for the wheels to follow the same tracks that they made when pulling into the driveway.

Conventional Answer:

D. Yes

If you replay turning into the driveway in reverse (turn the steering wheel in the same places by the same amount, but in the opposite direction), the wheels will follow the same path.

Detecting MouseEnter and MouseLeave in a control that has lots of children controls (.Net)

Seems like I have been through this before. What I want to do is hide and show something, depending on whether the mouse is inside of a certain area. For instance, I have a container of some sort with lots of controls on it. When the mouse is anywhere inside of the container, I want a link to be visible. I can't simply use the MouseEnter/MouseLeave events on the container, because MouseLeave is triggered when the mouse enters a child control and the MouseEventArgs don't say anything about what control is being entered.

Reading and Writing Disk Images for Raspberry Pi

(What is a Raspberry Pi? It's an inexpensive minicomputer, popular with hobbyists and educators.)

After doing several saving and restoring several images, I have found tools and a method that I'm happy with. I am using these with Raspbian, but they would work with other flavors, too.

How to Run Different PiPresents Shows on Different Days of the Week

A PiPresents pipresents.wordpress.com/ show (we're talking about a Raspberry Pi running Raspbian) can be set to end at a time of day, but it does not have a way to set a day of the week. I have created a workaround for this using the standard Linux cron scheduler and some bash scripts.

Say Goodbye to Windows 8's Start Screen

All of the people I've talked to who don't like Windows 8, don't like it because of the new start screen. You know, the tiled "apps" screen. A.K.A. "Metro" screen.

Maybe that sort of thing makes sense on a touchscreen device. Not on a desktop computer or standard laptop.

This free software brings back your start menu, like in Windows 7: ClassicShell. If you set it to start in desktop mode, you can say goodbye to the start screen! Here's how.
