Load package dynamically

No, Go doesn’t support dynamically loaded libraries. Your best bet is to start the plugin as its own executable and communicate with it through sockets or via stdin/stdout. 2017 update This answer is no longer true, Go now supports plugins (for Linux and MacOS only as of June 2021)

UIStoryboard: What’s the Correct Way to Get the Active Storyboard?

In case you want to get the active storyboard for a viewController, there’s a storyboard property. This is how I solved it, instead of making a new instance: LoginViewController *vc = [navController.storyboard instantiateViewControllerWithIdentifier:@”firstLaunch”]; [navController presentModalViewController:vc animated:YES]; In Swift you’d call: let loginViewController = navigationController?.storyboard?.instantiateViewController(withIdentifier: “firstLaunch”) as! LoginViewController navigationController?.present(loginViewController, animated: true, completion: nil) You could also … Read more

What might be the cause of ‘invalid value encountered in less_equal’ in numpy

That’s most likely happening because of a np.nan somewhere in the inputs involved. An example of it is shown below – In [1]: A = np.array([4, 2, 1]) In [2]: B = np.array([2, 2, np.nan]) In [3]: A<=B RuntimeWarning: invalid value encountered in less_equal Out[3]: array([False, True, False], dtype=bool) For all those comparisons involving np.nan, … Read more

how can I debug a jar at runtime?

How JVM stack, heap and threads are mapped to physical memory or operation system

What I don’t understand is that since JVM is essentially a software, how are those JVM heap, stack and threads mapped to physical machine? The heap is a pre-allocated continuous region of virtual memory. e.g. void* heap = malloc(Xmx); // get the maximum size. The stacks are allocated by the threading library when the thread … Read more
