You also cannot directly call list in IPython, as it conflicts with a command for listing lines of code.
Tested on this file:
def gen():
yield 1
yield 2

Why are mutable structs “evil”?
...

How to initialize a struct in accordance with C programming language standards
... 89.
ANSI C 89 allows you to initialize a struct this way:
typedef struct Item {
int a;
float b;
char* name;
} Item;
int main(void) {
Item item = { 5, 2.2, "George" };
return 0;

Running multiple AsyncTasks at the same time — not possible?
...lt;Runnable>(128);
This change increases the size of the queue to 128 items and reduces the maximum number of threads to the number of CPU cores * 2 + 1. Apps can still submit the same number of tasks.
