What is the fastest way to get the value of π?
...ll depends on what kind of accuracy you are looking for. The fastest π I know of is the one with the digits hard coded. Looking at Pi and Pi[PDF], there are a lot of formulae.
Here is a method that converges quickly — about 14 digits per iteration. PiFast, the current fastest application, uses t...
When should one use a spinlock instead of mutex?
...y'll need quite a lot of CPU instructions and thus also take some time. If now the mutex was only locked for a very short amount of time, the time spent in putting a thread to sleep and waking it up again might exceed the time the thread has actually slept by far and it might even exceed the time th...
What is the difference between a heuristic and an algorithm?
...defined. The solution could or could not be the best possible one but you know from the start what kind of result you will get. You implement the algorithm using some programming language to get (a part of) a program.
Now, some problems are hard and you may not be able to get an acceptable solution...
Make Iframe to fit 100% of container's remaining height
... I wasn't wrong already when I posted this, but this certainly is outdated now. Today you can do this in your stylesheet: html, body { height: 100% } and it will actually stretch to the whole of your viewport. Even with a DOCTYPE. min-height: 100% could also be useful, depending on your situation.

What is the difference between canonical name, simple name and class name in Java Class?
...n that would allow a malicious actor to work. Someone saying "oh, well we know classes will never start with lowercases/packages will never start with capitals". Granted, a malicious actor who has access to your class loader can already do terrible things, so it's probably not an absolutely terrible...

What's the recommended way to extend AngularJS controllers?
...ervice. The only thing you do is to directly expose that service. I don't know if that's a good idea. Your approach also fails if access to the scope is needed. But following your reasoning I would explicitly expose the scope as a property of the scope to the view so that it can be passed as an argu...
slim dynamic conditional class [closed]
...
If you have multiple conditions I am doing right now something like
div class=(('foo ' if is_foo?) + ('bar' if is_bar?))
Though I feel it to be a blemish if is_bar? return false and the generated HTML results in
<div class="foo "></div>
(the blemish is the...
Visual Studio 2012 Web Publish doesn't copy files
...a fresh Visual Studio 2012 project. It published over FTP in the past, but now when I try to Publish it does exactly as above - it pretends to, says it was successful, and pushes nothing. It does build the output to the obj dir, but it never actually copies it to the server. The change Configuration...
Is Ruby pass by reference or by value?
... Ruby is pass-by-value. No ifs. No buts. No exceptions. If you want to know whether Ruby (or any other language) is pass-by-reference or pass-by-value, just try it out: def foo(bar) bar = 'reference' end; baz = 'value'; foo(baz); puts "Ruby is pass-by-#{baz}".
