How do I tokenize a string in C++?
...ybe, but then we’re forced to perform (potentially redundant and costly) allocations.
Instead, C++ offers a plethora of ways to split strings based on arbitrarily complex delimiters, but none of them is encapsulated as nicely as in other languages. The numerous ways fill whole blog posts.

count vs length vs size in a collection
... - check source/documentation.
Capacity() - used to specifically refer to allocated space in collection and not number of valid elements in it. If type has both "capacity" and "size" defined then "size" usually refers to number of actual elements.
I think the main point is down to human language a...
What is string_view?
...or increasing the efficiency by avoiding unneeded copies (think of all the allocations and exceptions you can save).
The original C strings were suffering from the problem that the null terminator was part of the string APIs, and so you couldn't easily create substrings without mutating the underly...
Best practice using NSLocalizedString
...ic void staticInit_singleton()
{
singleton = [[LocalizationHandlerUtil alloc] init];
}

{
// default localized string loading
NSString * localizedString = [[NSBundle mainBundle] localizedStringForKey:key value:key ...
Heavy usage of Python at Google [closed]
... C++ and they spend 10% of their time tracking down bugs related to memory allocation, guess who's done faster - even if the C++ shop manages to write the rest of their code just as fast.
So yes, I'd say it is a competitive advantage to code in Python.

What are Long-Polling, Websockets, Server-Sent Events (SSE) and Comet?
... would every client connected to my server using ws: would have one thread allocated to him/her and its size would be ~2mb as is the case with normal requests? how would that differ in nodejs? How many concurrent clients can nodejs handle and when it breaks what happens?

How to make a flat list out of list of lists?
...ps getting longer, at each step a new intermediate result list object gets allocated, and all the items in the previous intermediate result must be copied over (as well as a few new ones added at the end). So, for simplicity and without actual loss of generality, say you have L sublists of I items e...

Split a collection into `n` parts with LINQ?
...reate the linked list until you reach the first item - that way there's no allocation if the source is empty

Combine multiple Collections into a single logical Collection?
... how, the underlying objects in the lists aren't copied and ArrayList just allocates the space and calls System.arraycopy() under the hood. Can't get much more efficient than that.
