There was an old piece of Sun documentation, Java Platform Performance (link sadly now broken, and I haven’t been able to find a new one), which described a situation where nulling a local variable which dropped out of scope actually had an effect on the GC. However, the paper referred to a very old version … Read more
Yes, local notifications work with the simulator. However, make sure you are implementing application:didreceiveLocalNotification in your app delegate if you want to see the notification while your app is in the foreground: – (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@”MyAlertView” message:notification.alertBody delegate:self cancelButtonTitle:@”OK” otherButtonTitles:nil]; [alertView show]; if (alertView) { [alertView release]; … Read more
This is currently possible in environments with Proxies. That would be node > 0.6 run as node –harmony_proxies or >0.7 with node –harmony. Chromium Canary (not sure if it’s out of that yet) in about:flags at the bottom, experimental javascript. Firefox has had it for a while with no flags. So this probably won’t work … Read more
Here are two methods to achieve the same thing: Using parameters and return (recommended) def other_function(parameter): return parameter + 5 def main_function(): x = 10 print(x) x = other_function(x) print(x) When you run main_function, you’ll get the following output >>> 10 >>> 15 Using globals (never do this) x = 0 # The initial value … Read more
I believe you’re correct in seeing this as a “mutability” problem. While the code you posted does throw an “UnboundLocalError”, the following code does not: def outer(): a = 0 def inner(): print a inner() outer() Python doesn’t allow you to reassign the value of a variable from an outer scope in an inner scope … Read more

Use docker cp. docker cp c:\path\to\local\file container_name:/path/to/target/dir/ If you don’t know what’s the name of the container, you can find it using: docker ps –format “{{.Names}}”
First, access your .bash_profile file by typing the following (using vim as text editor): vim ~/.bash_profile Inside the file .bash_profile, insert the following line: export LC_ALL=en_US.UTF-8 Note, however, that newer versions of macOS ship with zsh instead of bash as the default shell. If this is the case with your Mac, you will have to … Read more
You can name your local strategies to separate them. // use two LocalStrategies, registered under user and sponsor names // add other strategies for more authentication flexibility passport.use(‘user-local’, new LocalStrategy({ usernameField: ’email’, passwordField: ‘password’ // this is the virtual field on the model }, function(email, password, done) { User.findOne({ email: email }, function(err, user) { … Read more
There’s no need for a server if using PHP 5.5+ – it has a built-in server (http://www.php.net/manual/en/features.commandline.webserver.php) Just use: $ cd ~/public_html $ php -S localhost:8000
