We like Raspberry Pi, and we wonder which distribution are we using now. Do this to find out yourself:
$ readelf -A /proc/self/exe | grep Tag_ABI_VFP_args
Tag_ABI_VFP_args: VFP registers
If the Tag_ABI_VFP_args tag is found, then you're running on an ARMHF system. If nothing is returned, then it's ARMEL. The example above indicates an armhf distro. And the below:
$ pi@raspberrypi:~$ readelf -A /proc/self/exe | grep Tag_ABI_VFP_args
Nothing returned indicates that this is indeed ARMEL, which is the soft-float Debian Wheezy distribution.

Learning Impress.js
Tags:

presentation
Here I'll show you how to create the 1st presentation that use Javascript (impress.js).
From the template.html, copy and make your own the 1st impress.js's presentation.
The very 1st slide is always at the position (0,0,0) for x,y,z. Usually you only start add in the animation from slide 2 onward. Below are the only commands that you need to learn how to animate the slide transition.
Example, I'm creating 4 slides, and wish them to rotate to right like a cube.
Setup the 1st template.html
<!doctype html>
<html>
<head>
<title>Impress Tutorial</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
<div class="step"> My 1st slide </div>
<script type="text/javascript" src="impress.js"></script>
<script>impress().init()</script>
</body>
</html>
From the template.html, copy and make your own the 1st impress.js's presentation.
The very 1st slide is always at the position (0,0,0) for x,y,z. Usually you only start add in the animation from slide 2 onward. Below are the only commands that you need to learn how to animate the slide transition.
- data-x="800" - Positive (move-to-right), Negative (move-to-left)
- data-y="500" - Positive (move-down), Negative (move-to-up)
- data-z="1200" - Positive (come-close), Negative (go-far)
- data-scale="5" - Scale X times (1: original; x: bigger; 0.x: smaller)
- data-rotate-x="90" - 3D sliding. Positive (rotate-to-up-degree), Negative (rotate-to-down-degree)
- data-rotate-y="180" - 3D sliding. Positive (rotate-to-left-degree), Negative (rotate-to-right-degree)
- data-rotate-z="270" - 3D sliding. Rotated about the z-axis.
Example, I'm creating 4 slides, and wish them to rotate to right like a cube.
<div class="step"> My 1st slide </div>
<div class="step" data-rotate-y="90"> My 2nd slide </div>
<div class="step" data-rotate-y="180"> My 3rd slide </div>
<div class="step" data-rotate-y="270"> My 4th slide </div>
