Sync version of async method
Have a look at CountDownLatch. You can emulate the desired synchronous behaviour with something like this: private CountDownLatch doneSignal = new CountDownLatch(1); void main() throws InterruptedException{ asyncDoSomething(); //wait until doneSignal.countDown() is called doneSignal.await(); } void onFinishDoSomething(){ //do something … //then signal the end of work doneSignal.countDown(); } You can also achieve the same behaviour using … Read more
Asynchronous and Synchronous Terms
Indeed, it’s one of these cases, where original meaning of the word was subverted and means something different than in popular usage. ‘Synchronisation’ in telecommunication means that receiver signals whenever it is ready to receive messages, and only after this signal the transmitter will start transmitting. When the transmitter is done with the message, it … Read more
What’s the differences between blocking with synchronous, nonblocking and asynchronous? [duplicate]
Blocking may or may not be the same as synchronous, depending on the context. When we talk about method calls, then a synchronous call can also be said to be blocking (I’ll get back to this in a bit), because the thread calling the method cannot proceed forward until the method returns. The antonym in … Read more

How to include JSON data in javascript synchronously without parsing?
getJSON() is simply shorthand for the ajax() function with the dataType:’json’ set.

Does a thread waiting on IO also block a core?
A CPU core is normally not dedicated to one particular thread of execution. The kernel is constantly switching processes being executed in and out of the CPU. The process currently being executed by the CPU is in the “running” state. The list of processes waiting for their turn are in a “ready” state. The kernel … Read more
Wait for Shell to finish, then format cells – synchronously execute a command
Try the WshShell object instead of the native Shell function. Dim wsh As Object Set wsh = VBA.CreateObject(“WScript.Shell”) Dim waitOnReturn As Boolean: waitOnReturn = True Dim windowStyle As Integer: windowStyle = 1 Dim errorCode As Long errorCode = wsh.Run(“notepad.exe”, windowStyle, waitOnReturn) If errorCode = 0 Then MsgBox “Done! No error to report.” Else MsgBox “Program … Read more
Change the asynchronous jQuery Dialog to be synchronous?
The short answer is no, you won’t be able to keep your code synchronous. Here’s why: In order for this to be synchronous, the currently executing script would have to wait for the user to provide input, and then continue. While there is a currently executing script, the user is unable to interact with the … Read more
JS – Can’t combine lib files
Most probably one of your js files is missing a ; at the end. Open up the one you believe is causing the error and add a ; at the end, or add a ; to the very first line of the next js file.
