Is it possible to print a variable's type in standard C++?
...is answer from Jamboree shows how to get the type name in C++14 at compile time. It is a brilliant solution for a couple reasons:
It's at compile time!
You get the compiler itself to do the job instead of a library (even a std::lib). This means more accurate results for the latest language featu...
~x + ~y == ~(x + y) is always false?
...refore I would say code that makes that assumption is bad code most of the time. (Particularly when there are usually better ways of messing with signed numbers than bit twiddling; and particularly when unsigned numbers are probably a better choice most of the time anyway)

Get Element value with minidom with Python
...ow this question is pretty old now, but I thought you might have an easier time with ElementTree
from xml.etree import ElementTree as ET
import datetime
f = ET.XML(data)
for element in f:
if element.tag == "currentTime":
# Handle time data was pulled
currentTime = datetime.dat...
Split large string in n-size chunks in JavaScript
...hort strings (even with cached regex - probably due to regex parsing setup time)
match is even more inefficient for large chunk size (probably due to inability to "jump")
for longer strings with very small chunk size, match outperforms slice on older IE but still loses on all other systems

How do shift operators work in Java? [duplicate]
...intln(Integer.toBinaryString(2 << 11));
Shifts binary 2(10) by 11 times to the left. Hence: 1000000000000
System.out.println(Integer.toBinaryString(2 << 22));
Shifts binary 2(10) by 22 times to the left. Hence : 100000000000000000000000
System.out.println(Integer.toBinaryString(2...
MemoryCache does not obey memory limits in configuration

Wow, so I just spent entirely too much time digging around in the CLR with reflector, but I think I finally have a good handle on what's going on here.
The settings are being read in correctly, but there seems to be a deep-seated problem in the CLR itself that lo...
What is the default initialization of an array in Java?
... while creating the object and all the data values are initialized at that time.
For object of integer array type all values in the array are initialized to 0(zero) in the constructor method.
Similarly for object of boolean array, all values are initialized to false.
So Java is initializing the a...

I've noticed same thing on my browser some time ago.
Did you sing in to chrome using your Google account maybe? Or did you choose in any way to opt-out from collecting data on Google Analytics ?
Maybe Google remembers that option and uses it on Chrome when you are s...
Make sure only a single instance of a program is running
...e running instance. For example when the users starts the program a second time, you could send the running instance a command to tell it to open another window (that's what Firefox does, for example. I don't know if they use TCP ports or named pipes or something like that, 'though).
