C++ Object Instantiation
...
On the contrary, you should always prefer stack allocations, to the extent that as a rule of thumb, you should never have new/delete in your user code.
As you say, when the variable is declared on the stack, its destructor is automatically called when it goes out of scope...
Fastest way to tell if two files have the same contents in Unix/Linux?
...
Why don't you get the hash of both files content?
Try this script, call it for example script.sh and then run it as follows: script.sh file1.txt file2.txt
#!/bin/bash
file1=`md5 $1`
file2=`md5 $2`
if [ "$file1" = "$file2" ]
then
echo "Files have the same content"
else
echo "Files h...
Why prefer two's complement over sign-and-magnitude for signed numbers?
...o add them.
Two's complement addition is very simple. You add numbers normally and any carry bit at the end is discarded. So they're added as follows:
0010
+ 1111
=10001
= 0001 (discard the carry)
0001 is 1, which is the expected result of "2+(-1)".
But in your "intuitive" method, adding is m...

Sibling package imports
...ks well for private scripts, but there has been several improvements
Installing the package (in a virtualenv or not) will give you what you want, though I would suggest using pip to do it rather than using setuptools directly (and using setup.cfg to store the metadata)
Using the -m flag and runnin...
Align inline-block DIVs to top of container element
When two inline-block div s have different heights, why does the shorter of the two not align to the top of the container? ( DEMO ):

Easy way to list node modules I have npm linked?
...ts (e.g. ls -l node_modules | grep ^l)? They're normal symlinks.
If you really need to find all symlinks, you could try something like find / -type d -name "node_modules" 2>/dev/null | xargs -I{} find {} -type l -maxdepth 1 | xargs ls -l.

Difference between array_map, array_walk and array_filter

Check if two unordered lists are equal [duplicate]
...has a built-in datatype for an unordered collection of (hashable) things, called a set. If you convert both lists to sets, the comparison will be unordered.
set(x) == set(y)

Thanks....I removed all the files from the current branch and backed them up. Then switched branches and put them back. That worked. Also, thanks for the tip on the .gitignore though
