I would like to hear any practical uses of Digital Zoom.
I only see disadvantages of it like:
When enabled the quality drops
When enabled camera gets very sensitive so blurs
When enabled it's useless
I see it only as a way to crop the image but that can be done in software later and with better view of an image as well as you can select the part which you would like to crop.
So anyone, please state any useful example of digital zoom :)
I am curious to know.

It's a convenience feature for people who are not very intimate with digital image processing. And, in addition, the "zoomed" (cropped) image does not require as much disk space.

Looks like the lower portion of my LCD is trying to readjust its height.
This doesn't show up if I record the screen. It seems to only appear when displaying certain kinds of graphics... like the dark UIs of Blender and Adobe Illustrator. It also shows up if I play back a video of these troublesome GUIs in fullscreen!
What could be causing this?
EDIT: Fixed by moving the image up when the problem occurs.
It looks like your monitor is adjusting the screen to fit what it is being shown. It is probably a configuration problem. You should set it to "just scan" or whichever is the equivalent on your monitor.

I was just browsing http://plugins.netbeans.org/PluginPortal/
I like the way that the table at the bottom of the page works, with its various live filtering & sort options. Particularly its speed, fluidity & function.
Does anyone know how this would have been implemented (I'm talking specifically, I have a good understanding of the generalized process, and am interested in the specific technology if it already exists as a particular type of control in/on a particular platform)?
Your help would be greatly appreciated.
looking at the page source it looks like the DataTables plug in for jquery see here

I saw this awesome movie that I watched on DVD and wanted to take a screen shot of it, but when I did, it was transparent. I could only see my desktop taken but not the movie. Is there a specific program or hack that could let me take a screen shot of that content? I tried every screen shot software, but still leaves it transparent.
Try VLC player, under Menu->Video you should see 'Take Snapshot'. As far as I remember it worked for me while I had the same problem (though on windows).
Here is the download link:

Use proper player, such as KMPlayer. In there you can do PrintScreen or choose a variety of options:

Does any company offer an online rendering service for After Effects?
I have a file with 144 HD clips all masked, and my poor little macbook can't handle it (288 hours render time).
There are no effects, only masks, as it is, in effect, a pre-render.
If anyone has suggestions of how I can speed up this render, would be super appreciated.
Here's catalog of render form services wiht special topic about After Effects online http://rentrender.com/after-effects-render-farms/ and Cloud rendering http://rentrender.com/cloud-render-farms-list/ Look and choose what you want and make rendering of your clips
None that I know of. You can set up After Effects to render over a local network, of course you'll need multiple computers with After Effects installed. See here: http://help.adobe.com/en_US/AfterEffects/9.0/WS3878526689cb91655866c1103a4f2dff7-79a2a.html
There is a company that will be distributing extra CPU cycles but they are not operational yet. http://cpusage.com

I have always thought the way they zoom in and enhance on TV and movies was strictly impossible. Essentially because you cannot create more information that there is to begin with.
There were ways to get better looking or clearer images like with re-sampling, but never to the extent seen on film.
Now, it seems that is not true.
I was reading this article, and it seems they have a way to do that now?
Or, is this just a better version of what was already possible? You still need to have a fairly clear image to start with? Otherwise, what are the limits of this technique?
There is something called Super-resolution. Some companies claim to use fractal theory to enhance images when they are upscaled. But, what you see in most movies is just fiction.
Image enhancement always involves pixel interpolation (aka. prediction) - in one way or the other. Interpolation can be good, bad or whatever, but it will never out-perform real pixel which was recorded by imaging device at greater resolution.
