Technical Demos
Here are some assorted technical demos I've created. Mostly they
deal with client-side behavior such as JavaScript and the
<canvas> tag. A few are related to style.
The following are UI demonstrations relevant to the NRAO.
- baseband
- A visualization of basebands within some frequency
range. There's also an older version that
doesn't use Raphael
and an even older version
which is less HTML-driven
- subbands
- A visualization of subbands within a baseband, for
OSRO. There's also an older version that
does not use Raphael and an incomplete
version.
- frequency range
- A zoomable view of a set of lines against a frequency
range. There's also a stable
version in case I'm working on the main one.
The following are purely technical demos that have no particular
astronomical content.
- canvas libraries
- Demonstration of using various HTML 5 <canvas> libraries.
- client-side-persistence
- A demonstration of client side persistence libraries. Make
all the changes you want, when you come back they'll be
preserved.
- color
- Uses simulated annealing to generate a number of colors which
are distant from each other.
- decimal-alignment
- A trick for jQuery to align a column by decimal point
unobtrusively.
- html5
- Tests of various HTML 5 capabilities.
- layout
- A proper CSS layout for the OPT. Not integrated yet and may
be a long time coming.
- slider
- A simple demonstration of a jQuery UI slider.
Up a level.
