How to deserialize a list using GSON or another JSON library in Java?
... hassle with the Type object, and if you really need a list you can always convert the array to a list, e.g.:
List<Video> videoList = Arrays.asList(videoArray);
IMHO this is much more readable.
In Kotlin this looks like this:
Gson().fromJson(jsonString, Array<Video>::class.java)

Explicitly calling return in a function or not
...eated from data selected this way:
bench_nor2 <- function(x,repeats) { system.time(rep(
# without explicit return
(function(x) vector(length=x,mode="numeric"))(x)
,repeats)) }
bench_ret2 <- function(x,repeats) { system.time(rep(
# with explicit return
(function(x) return(vector(length=x,mode...
Why does the indexing start with zero in 'C'?
...pression (such as the name of an array object) is usually, but not always, converted to a pointer to the first element. Example: sizeof arr yields the size of the array object, not the size of a pointer.

'and' (boolean) vs '&' (bitwise) - Why difference in behavior with lists vs numpy arrays?
...f the statement 'my car has wheels') => number
If python knows how to convert the statements to numeric values, then it will do so and compute the bitwise-and of the two values. This may lead you to believe that & is interchangeable with and, but as with the above example they are different...
Append a NumPy array to a NumPy array
...
Actually one can always create an ordinary list of numpy arrays and convert it later.
In [1]: import numpy as np
In [2]: a = np.array([[1,2],[3,4]])
In [3]: b = np.array([[1,2],[3,4]])
In [4]: l = [a]
In [5]: l.append(b)
In [6]: l = np.array(l)
In [7]: l.shape
Out[7]: (2, 2, 2)
In [8]...

(![]+[])[+[]]… Explain why this works
...e second operand of the addition, an empty Array, [], this is made just to convert the false value to String, because the string representation of an empty array is just an empty string, is equivalent to:

Error handling in C code
...ints or different enumerations with return-codes.
provide a function that converts errors into something human readable. Can be simple. Just error-enum in, const char* out.
I know this idea makes multithreaded use a bit difficult, but it would be nice if application programmer can set an global err...
How to call erase with a reverse iterator
...
And here is the piece of code to convert the result of erase back to a reverse iterator in order to erase an element in a container while iterating in the reverse. A bit strange, but it works even when erasing the first or last element:
std::set<int> ...
