do they store the hashes of the videos and then compare them? how do they know that you had already uploaded that video? there are plenty of videos on you tube that have the same file name and file size.
They likely do hashes. But since Google acquired YouTube, there's a lot more intelligence in their code. Google and others have been working on creating "digital fingerprints" for media like movies, where defining characteristics become part of the same result even if the file is mildly tampered with. Because this is an ongoing race between (loosely speaking) "pirates" and "the Powers That Be," there's research ongoing on both sides of the fence, and the algorithms involved are likely to be kept as industry secrets.
(a good excuse for me to only give you this vague, hand-waving explanation instead of some useful facts).

I am currently reading "REST in Practice", which is getting a bit long in the tooth by technical book standards (2009), but it came highly recommended to me as a book that still has a lot of pertinent information for today's world. One of the topics that has particularly caught my interest is the use of Atom feeds to publish events.
Reading the chapter focused on Atom got my very excited to look into replacing the home-grown/custom solution the company I work at has developed to solve the same problem (delivering a feed of events over a RESTful API)...however, I started doing some follow up research and found that development/interest in the various Atom libraries out there (like Apache Abdera and ROME) seem to suffer from dwindling community interest.
Is Atom still being used for this purpose (event feeds), or has another solution come into favor?

I am trying to build a webpage that shows the video of a webcam on live.
Right now, I have no webcam, so I'll have to buy one. I don't mind how much it costs, I just want it working with a good resolution (at least 720p).
I don't know which kind of camera I should buy and which programming language is better for that (if it's possible I would prefer not to use Flash).
Can you help me?
Sorry for my bad English, I'm trying to improve ;)

To show in a webpage, you can use IP-Camera. They cost a little more, but they can serve their images as independent network node. They also supports voice and live compression (H264 and MPEG4).
Best brand is Axis, but there are lots of options.
For Axis camera models, adding view to page would be as easy as add this item to your page:
<img src='http://192.168.1.20/axis-cgi/mjpg/video.cgi'>
It works for most browser, not IE. For IE, they have support as well here.

I'm in the process of writing a program that requires a long list of words to function. I have one on my computer, but I don't remember its source, and I was only using it to learn, so I paid no attention to where I got it. But now that I'm seriously considering writing and publishing this iOS app (eventually), I get the feeling that whoever made this list would not be happy if I made profit or even published something that contains their own work. Do you know of any word lists in .txt format that I could use for publishing a possibly paid iOS app?
Search for "open source word lists". Some examples include Kevin's Word List and The English Open Word List

I'm looking for details about how linkedIn manages "Search Skills & Expertise". Somebody knows how tags comparison could work? On what algorithms developers could have based the tag comparing system? Something like a "binary independent model" - like? Every supposition or infos are welcome. I'm trying to think about a system that relates tag like linkedIn "Search Skills & Expertise", so I would start with some good incipit, studying some web information retrieval material and asking to someone who knows more than me about this argument.
Thank you.
Have you asked LinkedIn?
Also they recently released IndexTank as open source sorftware and this is the engine they use for searching and indexing and i suspect that would give you information as you can dow=nload and run it yourself.

Developing software solutions which already exist and are available for re-use (either commercial or open-source). AKA "re-inventing the wheel".
Same as above, but your solution being broken. AKA "re-inventing the square wheel".
Developing solutions for problems which do not exist.
Again, I'm interested in a more formal approach, e.g. TRIZ
Doing some research beforehand (1) and investing in solid software architecture (2,3) usually helps :)
When you're planning to develop something you always need to calculate the benefits of doing some and the things like the ROI.
