Microsoft first released a version of C# with async/await in the Async CTP (2011). It was later officially released in C# 5 (2012). [7] [1]: 10 Haskell lead developer Simon Marlow created the async package in 2012. [8] Python added support for async/await with version 3.5 in 2015 [9] adding 2 new keywords, async and await.
Delta time or delta timing is a concept used amongst programmers in relation to hardware and network responsiveness. [1] In graphics programming, the term is usually used for variably updating scenery based on the elapsed time since the game last updated, [2] (i.e. the previous "frame") which will vary depending on the speed of the computer, and how much work needs to be done in the program at ...
Thread 0: Will be sleeping for 3 seconds. Thread 1: Started. Thread 1: Will be sleeping for 5 seconds. Thread 2: Will be sleeping for 4 seconds. Thread 4: Started. Thread 4: Will be sleeping for 1 seconds. In main: All threads are created. Thread 3: Will be sleeping for 4 seconds. Thread 4: Ended. Thread 0: Ended. In main: Thread 0 has ended ...
In computer science and software engineering, busy-waiting, busy-looping or spinning is a technique in which a process repeatedly checks to see if a condition is true, such as whether keyboard input or a lock is available. Spinning can also be used to generate an arbitrary time delay, a technique that was necessary on systems that lacked a ...
On Unix-like and other POSIX operating systems, the sleep() function is called providing a single parameter of type unsigned integer of the number of seconds to sleep. [3] A higher-precision version is the nanosleep() function and the now deprecated usleep. [4] POSIX also allows for choosing clock sources via the extended version clock ...
wait normally returns the exit status of the last job which terminated. It may also return 127 in the event that n specifies a non-existent job or zero if there were no jobs to wait for. Because wait needs to be aware of the job table of the current shell execution environment, it is usually implemented as a shell builtin .
Do not make multi-threaded requests. Wait for one server request to complete before beginning another. Back off upon receiving errors from the server. Errors such as timeouts are often an indication of heavy server load. Use a sequence of increasingly longer delays between repeated requests. Make use of assertion to ensure your bot is logged in.
CPU-bound jobs will spend most of their execution time on actual computation ("number crunching" [1]) as opposed to e.g. communicating with and waiting for peripherals such as network or storage devices (which would make them I/O bound instead).
