...vely operated, this function gradually switches everything down (display, CPU, WiFi, etc.). In order to bypass Doze mode effectively, it is necessary to create a foreground service. A lot of useful background information can be found in the ZEBRA Developer Portal: Keeping your Android application...
What are some uses of template template parameters?
...type float and on GPU, but connection_matrix will always be int, either on CPU (by specifying TT = Tensor) or on GPU (by specifying TT=TensorGPU).

What is the performance cost of having a virtual method in a C++ class?

How do I create a unique constraint that also allows nulls?
...onal disk space.
Note that if you don't want an index, you can still save CPU by making the expression be precalculated to disk by adding the keyword PERSISTED to the end of the column expression definition.
In SQL Server 2008 and up, definitely use the filtered solution instead if you possibly ca...

Best approach to real time http streaming to HTML5 video client
... HTML5 client (involves re-encoding, so expect quality loss and needs some CPU-power):
Set up an icecast server (could be on the same machine you web server is on or on the machine that receives the RTSP-stream from the cam)
On the machine receiving the stream from the camera, don't use FFMPEG but...
In which order should floats be added to get the most precise result?
...bly avoid using -ffast-math but that in many applications where you may be CPU-bound but don't care about precise numerical computations, (game programming for instance), -ffast-math is reasonable to use. Thus, I'd like to ammend my strongly worded "banned" comment.

How slow are .NET exceptions?
...are implemented as Win32 SEH exceptions, so some will even pass the ring 0 CPU boundary!
Obviously in the real world, you'll be doing a lot of other work so the odd exception will not be noticed at all, but if you use them for program flow expect your app to be hammered. This is another example of ...
What are the dangers when creating a thread with a stack size of 50x the default?
...d the local variables in a method. Minus the ones that can be stored in a CPU register, you can ignore that since there are so few of them.
Increasing the stack size doesn't accomplish anything, you'll just reserve a bunch of address space that will never be used. There is no mechanism that can e...
