Ways to save Backbone.js model data?
...er side. This could just be the ID of your donut resource in your database table.
If I make a PUT to that URI with new data, I'd be updating it, saving over it. And if I DELETE to that URI, then it would purge it from my system.
With POST, since you haven't created a resource yet it won't have an ...

Releasing memory in Python
...le.
The costs are:
Process startup is kind of slow on some platforms, notably Windows. We're talking milliseconds here, not minutes, and if you're spinning up one child to do 300 seconds' worth of work, you won't even notice it. But it's not free.
If the large amount of temporary memory you use r...
In plain English, what does “git reset” do?
... though. In particular, if you take the time to carefully read them, those tables detailing states of files in index and work tree for all the various options and cases are very very helpful.

“Keep Me Logged In” - the best approach
...in, generate a large (128 to 256 bit) random token. Add that to a database table which maps the token to the userid, and then send it to the client in the cookie.
What if the attacker guesses the random token of another user?

What are some (concrete) use-cases for metaclasses?

On Linux? Yes.
On Windows? Only special characters available for the current locale of the Windows user.

What's the best way to communicate between view controllers?
... up and push the controller onto the stack. But as I've become more comfortable with the SDK, I've drifted away from that, and now I usually have the parent push the child.
For #3, consider this example. Here we are using two controllers, AmountEditor and TextEditor, to edit two properties of a T...
