Apache JMeter

Opensource: APACHE LICENSE, VERSION 2.0
Website: http://jmeter.apache.org/

What can I do with it?

Apache JMeter may be used to test performance both on static and dynamic resources.

It can be used to simulate a heavy load on a server, group of servers, network or object to test its strength or to analyze overall performance under different load types.

You can use it to make a graphical analysis of performance or to test your server/script/object behavior under heavy concurrent load.

Limitations

JMeter does not perform all the actions supported by browsers.

In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does.

Jenkins

Visualization with Performance Plugin.

Jmeter as a Proxy

JMeter can be used for recording HTTP/HTTPS traffic.

Slides

Not a coder? Not a problem. There's a fully-featured visual editor for authoring these, try it out at http://slides.com.

Point of View

Press ESC to enter the slide overview.

Hold down alt and click on any element to zoom in on it using zoom.js. Alt + click anywhere to zoom back out.

Touch Optimized

Presentations look great on touch devices, like mobile phones and tablets. Simply swipe through your slides.

Transition Styles

You can select from different transitions, like:
None - Fade - Slide - Convex - Concave - Zoom

Themes

reveal.js comes with a few themes built in:
Black (default) - White - League - Sky - Beige - Simple
Serif - Blood - Night - Moon - Solarized

Background Transitions

Different background transitions are available via the backgroundTransition option. This one's called "zoom".

Reveal.configure({ backgroundTransition: 'zoom' })

Background Transitions

You can override background transitions per-slide.

<section data-background-transition="zoom">

Pretty Code

function linkify( selector ) {
  if( supports3DTransforms ) {

    var nodes = document.querySelectorAll( selector );

    for( var i = 0, len = nodes.length; i < len; i++ ) {
      var node = nodes[i];

      if( !node.className ) {
        node.className += ' roll';
      }
    }
  }
}

Clever Quotes

These guys come in two forms, inline: “The nice thing about standards is that there are so many to choose from” and block:

“For years there has been a theory that millions of monkeys typing at random on millions of typewriters would reproduce the entire works of Shakespeare. The Internet has proven this theory to be untrue.”

Intergalactic Interconnections

You can link between slides internally, like this.

Speaker View

There's a speaker view. It includes a timer, preview of the upcoming slide as well as your speaker notes.

Press the S key to try it out.

Export to PDF

Presentations can be exported to PDF, here's an example:

Global State

Set data-state="something" on a slide and "something" will be added as a class to the document element when the slide is open. This lets you apply broader style changes, like switching the page background.

State Events

Additionally custom events can be triggered on a per slide basis by binding to the data-state name.

Reveal.addEventListener( 'customevent', function() {
	console.log( '"customevent" has fired' );
} );
					

Take a Moment

Press B or . on your keyboard to pause the presentation. This is helpful when you're on stage and want to take distracting slides off the screen.
