JavaScript hashmap equivalent
...uild a class parameterized by the key function, and with all the necessary API of the container, but … we use JavaScript, and trying to be simple and lightweight, so this functional solution is simple and fast.
The key function can be as simple as selecting right attributes of the object, e.g., a ...
Why should I avoid using Properties in C#?
...
@Patrick: No, it brings the benefit of separating API from implementation - you can later change how the property is computed from the field (e.g. to compute two related properties from one field).

If you're adding constraints in code, you should do this once from within the updateConstraints method of your UITableViewCell subclass. Note that updateConstraints may be called more than once, so...

C++ performance vs. Java/C#
...ode (e.g. a generic parser from string to type T, calling standard library API for types T it recognizes, and making the parser easily extensible by its user) is very easy and very efficient, whereas the equivalent in Java or C# is painful at best to write, and will always be slower and resolved at ...
What are the differences between the threading and multiprocessing modules?
...sing module. (You can use multiprocessing.dummy to get most of the missing API on top of threads, or you can use higher-level modules like concurrent.futures and not worry about it.)

Big O, how do you calculate/approximate it?
...oop, as function calls can do > O(1) work themselves. In the C standard APIs for instance, bsearch is inherently O(log n), strlen is O(n), and qsort is O(n log n) (technically it has no guarantees, and quicksort itself has a worst case complexity of O(n²), but assuming your libc author isn't a m...
What are the effects of exceptions on performance in Java?
...ating that a method might fail. There's no other way to tell from just the API which methods are expected to always (mostly) work and which are expected to report failure.
Exceptions are safer than sentinels, faster than result objects, and less surprising than either. I'm not suggesting that try/c...
What does the Java assert keyword do, and when should it be used?
... I don't agree. Many of my assertions are used to make sure my API is getting called correctly. For example, I might write a private method that should only be called when an object holds a lock. If another developer calls that method from part of the code that doesn't lock the object, t...
