问题 I am trying to create an xls sheet programmatically. To fill the sheet, I am making the multiple NSURLConnection around 100. Right now, my approach is : Make a connection and store the data into an array . This array has 100 objects. Now take the first object and call the connection . Store the data. And make the second connection with 2nd object in the array. This continues till the last object in the array. It takes on average 14 seconds to finish the 100 connections. Is there any way to

Asynchronous method call in Python without creating threads or forking process?

Some years ago, (for comparison) synchronous JavaScript ajax requests were deprecated because of the overhead. I’m in the following situation : def ssh_network_operation_with_paramiko(string): server_response=Do_some_stuff_with_null_characters_in_string(string) Do_something_with_server_response(server_response) for i in very_very_large_range ssh_network_operation_with_paramiko(i) Basically, using process or threads would be synonym of creating a fork bomb. So is it possible to do perform asynchronous calls without creating threads or process like with ajax in JavaScript ? Because all I found

Sorry for the noob question, but I'm trying to test a connection, but I'm not able do verify the return of the request, because the test ends before the completion handler have a chance to execute. To ilustrate: -(void)testConnection { [[Conector sharedInstance] performAsynchronousRequestWithServerRequest:_srvRequest completionHandler:^(RequestAsynchronousStatus finishStatus, NSData *data) { if (finishStatus == RequestAsynchronousOK){ _data = data; NSLog(@"Data OK"); } }]; XCTAssertNotNil(_data, @"Data was nil"); } When I try to assert, _data will always be nil, because the completion handler

I am experimenting in tableView:cellForRowAtIndexPath to set an image by calling [self downloadImage:urlString andSetIntoCellImageView:cell] and in downloadImage , it will call NSURLConnection:sendAsynchronousRequest (iOS 5 and up only), and in the completion block, set the image by using cell.imageView.image = [UIImage imageWithData:data]; // data is downloaded data and it works if in tableView:cellForRowAtIndexPath , the imageView is populated with a dummy placeholder image -- and I wonder how the new image is refreshed, is it by setNeedsDisplay to do a repaint? But if I don't set the
