Screencasting Framework

The following document is a written account of the Code School screencasting framework. It should be used as a reference of the accompanying screencast on the topic.

Why you should care about screencasting?

You're probably aren't going to take the time to read this document if you're not interested, but there are a lot of nice side effects caused by learning how to create quality screencasts.

1. Communicating more effectively - At Envy Labs we produce screencasts for our clients all the time. Whether it's demoing a new feature or for a presentation for an invester, they're often much more effective and pleasent than a phone call or screen sharing.

eXtreme Go Horse (XGH) Process

Source: http://gohorseprocess.wordpress.com


1. I think therefore it's not XGH.
In XGH you don't think, you do the first thing that comes to your mind. There's not a second option as the first one is faster.

2. There are 3 ways of solving a problem: the right way, the wrong way and the XGH way which is exactly like the wrong one but faster.
XGH is faster than any development process you know (see Axiom 14).

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

$ServerThreadCode = {
    $listener = New-Object System.Net.HttpListener
    $listener.Prefixes.Add('http://+:8008/')

    while ($listener.IsListening) {
 
        $context = $listener.GetContext() # blocks until request is received

Demonstrate Erlang's 'busy wait' effect on CPU utilization

How?

Just make Erlang to do some light-load task in a bunch of relatively short leaving processes. Calculating PI to 80th digit in batches per 10 procs with short, 8 ms, sleep in-between, to give schedulers a breath space, will do.

Running

Run erl with 8 schedulers and no busy waiting on schedulers at all.
