On a car with automatic transmission, is it better to put in "n"eutral every time you stop on a semaphore?

There any difference (with fuel and parts consumption for example), if you stop with the transmission in "d"rive or "n"eutral? Is it better to put the transmission in neutral to reduce DE parts consuming when you stop for more time, like on a semaphore?

Answer: It makes no difference we there in neutral or drive, however the engine tends to use more gas due to the engine load while in gear.

Can you lead someone out of his cave with semaphore?

T's say he's sitting at his computer, looking at the shadows on his high-definiteion screen and imagining them to be reality. Can you wave your flags at him in a wig-wag pattern to alert him?

Answer: Pray for the right answer

I need a simple c++ class's for implementing a simple semaphore. Do you have one?

Have a resource - handle - which I need to protect in a multi-thread application. Thus, I am looking for a simple implementation of a semaphore class's. Found some over the web, but even the simplest one was too complicated.

Answer: If you're using a proper OS (mac OS x, Linux, freebased, solar is, etc) then you should already have semaphores available without doing any extra work. Take a look at the routines in <semaphore. H>, in particular semen.

Is it necessary to use a semaphore in this situation?

Tipple threads have read/write access to an int variable. Is it necessary to protect this variable with a semaphore? Or should it be OK seeing as it's such a small thing?

Answer: It depends on the architecture but in general, yes you should. As an optimisation to reduce deadlock, as long as all the threads are reading only, you don't need to restrict access one thread at a time as the data is not being modified so any number of threads can read it at the same time. The only time you need to enforce the restriction is when a thread wants to write to the data and it can't start writing to the data until all the other threads have finished reading the data.

What is green, yellow, red that looks and acts like a semaphore but it is not actually a semaphore.?

Is is a work riddle I am not able to figure out and remember its not really a semaphore just acts like one.

Answer: A railroad signal. It has an arm with 3 coloured lenses, the arm moves into different positions indicating what the driver is expected to do, go ahead, take caution or stop. In each position, one of the 3 colour lenses is placed in front of a lamp, so at night the driver can go by light colour if he cannot see the semaphore arm position.
