Why does cURL return error “(23) Failed writing body”?
...
This happens when a piped program (e.g. grep) closes the read pipe before the previous program is finished writing the whole page.
In curl "url" | grep -qs foo, as soon as grep has what it wants it will close the read stream from curl. cURL doesn't expect this and emits the "Faile...
In-Place Radix Sort
... the temporary array fits into memory.
Reason:
The sorting does a linear read on the input array, but all writes will be nearly random. From a certain N upwards this boils down to a cache miss per write. This cache miss is what slows down your algorithm. If it's in place or not will not change thi...
How can I add to List
... object is allowed in that List. The only "guarantee" is that you can only read from it and you'll get a T or subclass of T.

If you need tuples:

Should I use past or present tense in git commit messages? [closed]
I read once that git commit messages should be in the imperative present tense, e.g. "Add tests for x". I always find myself using the past tense, e.g. "Added tests for x" though, which feels a lot more natural to me.

Using scanner.nextLine() [duplicate]
...
I think your problem is that
int selection = scanner.nextInt();
reads just the number, not the end of line or anything after the number. When you declare
String sentence = scanner.nextLine();
This reads the remainder of the line with the number on it (with nothing after the number I s...
