Split a string by another string in C#
...e it suddenly drags my attention from stream level to byte level. Anybody know why C# library guys designed the Split method like this? If there is a good reason, I can probably try to appreciate it despite the inconvenience.

Flatten nested dictionaries, compressing keys
...ems = []
for k, v in d.items():
new_key = parent_key + sep + k if parent_key else k
if isinstance(v, collections.MutableMapping):
items.extend(flatten(v, new_key, sep=sep).items())
else:
items.append((new_key, v))
return dict(items)

Is it possible to get the non-enumerable inherited property names of an object?
...etOwnPropertyNames(curr)
props.forEach(function(prop){
if (allProps.indexOf(prop) === -1)
allProps.push(prop)
})
}while(curr = Object.getPrototypeOf(curr))
return allProps
}
I tested that on Safari 5.1 and got

Why does int i = 1024 * 1024 * 1024 * 1024 compile without error?
...A VALUE(although 2147483648L is) in Java. The compiler literally does not know what it is, or how to use it. So it whines.
1024 is a valid int in Java, and a valid int multiplied by another valid int, is always a valid int. Even if it's not the same value that you would intuitively expect because t...
Use logging print the output of pprint
...
If you don't remove this code after you're done debugging, you should probably guard it with "if Logger.isEnabledFor(logging.DEBUG):" to avoid running pformat when you won't use its output: docs.python.org/2/library/…

When NOT to use yield (return) [duplicate]
...t);
}
}
which still uses yield return, but is much smarter about it. Now we are O(n) in time and O(h) in heap space, and O(1) in stack space.

How do I convert a double into a string in C++?
I need to store a double as a string. I know I can use printf if I wanted to display it, but I just want to store it in a string variable so that I can store it in a map later (as the value , not the key ).

Any way to properly pretty-print ordered dictionaries?
...
pprint.pprint(dict(data)) works well if you don't care about the order of the keys. Personally, I wish the __repr__ for OrderedDict would produce output like this but preserve the order of the keys.

What is the difference between the kernel space and the user space?
...ernel space in order to stop the users from messing up with the kernel, unknowingly.
So, when a system call occurs, a software interrupt is sent to the kernel. The CPU may hand over the control temporarily to the associated interrupt handler routine. The kernel process which was halted by the inter...
How to list branches that contain a given commit?
...ranch --contains <commit>
Only list branches which contain the specified commit (HEAD if not specified). Implies --list.
git branch -r --contains <commit>
Lists remote tracking branches as well (as mentioned in user3941992's answer below) that is "local branches that have a direct ...
