If you are writing this sort of software you ought to have a big book for the specification you are conforming to (FAA, NATO, FDA, whatever) of what you can and cannot do, and it will tell you .

If you choose to ignore my warning, here is some sample C++ code to do it .
The best way is to shut down the box lest you leave it in a dangerous state .

I was debugging a multi-threaded application and found the internal structure of CRITICAL_SECTION . I found data member LockSemaphore of CRITICAL_SECTION an interesting one.
It looks like LockSemaphore is an auto-reset event (not a semaphore as the name...

I've started a conversion of a project to Moose and the first thing I noticed was that my critic/tidy tests go to hell. Moose, Tidy and Critic don't seem to like each each other as much as they used to.
Are there docs anywhere on how to make critic/tidy...

I've written a simple test case based on Test::Perl::Critic which runs critic on every single source file in the repository ( all_critic_ok ). However, this test takes a long time, especially since I also use a Perl::Tidy policy.
Normally, criticizing...
