Why does Java allow us to compile a class with a name different than the file name?
...
The rationale is to allow more than one top-level class per .java file.
Many classes—such as event listeners—are of local use only and the earliest versions of Java did not support nested classes. Without this relaxation of the "filename = class ...
Are there any cases when it's preferable to use a plain old Thread object instead of one of the newe
...d not be taken away. However, for most people and most use cases there are more appropriate things to use which you mentioned, such as thread pools (which provide a nice way of handling many small jobs in parallel without overloading the machine by spawning 2000 threads at once), BackgroundWorker (w...
Get nth character of a string in Swift programming language
...The Substring type was introduced in Swift 4 to make substrings
faster and more efficient by sharing storage with the original string, so that's what the subscript functions should return.

Best way to convert string to bytes in Python 3?

Now the correct way is not to catch this exception or EmptyResultDataAccessException, but make sure the query you are using should return only one...
Should flux stores, or actions (or both) touch external services?
...nd it an action, and check to see if the state changed as expected. Furthermore, one of the core concepts in flux is to prevent cascading dispatches and to prevent multiple dispatches at once; this is very difficult to do when your stores do asynchronous processing.
All action dispatches happen from...
ETag vs Header Expires
...request to the server at all. The closer you are to the Expires date, the more likely it is the client (or proxy) will make an HTTP request for that file from the server.
So really what you want to do is use BOTH headers - set the Expires header to a reasonable value based on how often the content...
When do I really need to use atomic instead of bool? [duplicate]
...th wider ramifications (e.g. restrictions on compiler re-ordering). Furthermore, some operations (like negation) are overloaded on the atomic operation to create a distinctly different instruction on the hardware than the native, non-atomic read-modify-write sequence of a non-atomic variable.
