Executing periodic actions in Python [duplicate]
...foo (1421705503.5810)
Note that this example includes a simulation of the cpu doing something else for .3 seconds each period. If you changed it to be random each time it wouldn't matter. The max in the yield line serves to protect sleep from negative numbers in case the function being called takes...
Unable to load SOS in WinDbg
...nging to get both on my system, since the latest installers autodetect the CPU type. Is there an override flag that you know of for the msi? I'm going to install an old 32bit version of WinDbg, but don't know what to expect.

What's the difference between `1L` and `1`?
... large vectors, that's less wasted memory and less to wade through for the CPU (so it's typically faster).
Mostly this applies when working with indices.
Here's an example where adding 1 to an integer vector turns it into a double vector:
x <- 1:100
typeof(x) # integer
y <- x+1
typeof(y) # ...
What is the difference between using IDisposable vs a destructor in C#?
...ent but were abandoned without unsubscribing, that could cause a memory or CPU leak (since the time required to process each subscription would increase).

... mach_absolute_time is not uptime. It is roughly the amount of time the CPU has been active. mach_absolute_time mostly stops counting when the device sleeps.

Advantages of this method:
High CPU and MEMORY efficiency;
It is the fastest solution, 2.5 times faster than other's methods

Suitable for removing parts from the input string (set newValue to

A simple loop also reads more clearly. Here's the boilerplate of the two versions:

Is there a library function for Root mean square error (RMSE) in python?
...i-gigabyte sized libraries; requiring 3 to 20 minute Network download then CPU full-tilt installs, when all you really need is about 3 lines of code that fits in 400 bytes.
