I am beginner in HTML and CSS. I just designed web site and tried to validate but my HTML end up having some "geovisit();"
and it wont validate.
I do not know how to get rid of it.
Help me?
Thank you

A quick Google search for geovisit suggests that the non-validating code is being added by your hosting provider. It looks like this problem may actually be specific to Yahoo!, which has an option to disable that "feature". I suggest you read this forum thread on the problem.
That's usually Yahoo (or other hosting providers) sticking javascript on your page without your knowing. In Yahoo's case you should be able to turn it off if you dig through the settings.

Is there anyway that I can manipulate HTML in a Facebook post? Is it possible to edit the code in anyway without having to install a third-party app?
Sure, depending on which browser you are using, there are different ways. Just search for dev tools [your browser] and you will find a way. Guess it's mostly F12.
Of course that's just locally, you won't be able to change the data on the server, if you're not allowed to.
Right Click > Investigate or F12 on the Element you want to edit and on your right there should open the code you can freely edit it to your liking
Also when posting on SO please provide more than just saying i want to do that.. How to do it? Tell us what you have tried or where you have researched before asking the Question
While I was searching a website that helps me to obfuscate my html source.
I found this website.
http://snapbuilder.com/code_snippet_generator/obfuscate_html_source_code/
Do you guys think this website is reliable?
I am now learning about front-end stuff, so I am not sure this helper might have some harmful code.
Thank you
Do not do this, it will simply make your site slow, and if they have Javascript disabled your site will not function at all. Not to mention the fact that as soon as this script is executed they will still be able to see the HTML via the dev tools in any browser.
tl;dr DO NOT DO THIS
So I take this class, and I'm way ahead of everyone else and a lot of people steal code from my website, I have already disabled right clicking but it's rather easy to get around this, is their any way to stop people from being able to view my source code?
tl;dr: Nope.
You could look into obfuscation, as well as CSS & JS minification.
"If you steal from one author, it’s plagiarism; Steal from many, it’s art."
No, if someone wants it, they will get it, you can make it harder but, you will just alienate your users from normal functionality, focus on your backend code.
If they steal your code, your lector will hopefully notice, either way they only hurt themselves.
Afaik the only way to hide your source code is if you put it on the server-side.
It is not possible from hiding client-side source code from users - sorry.
One suggestion would be stopping the user from right-clicking but that might cause you more problems...
You could render the html pages server side and convert them into images which get sent to the client. You could then have some image maps that handle clicking on the various locations.
There isn't a perfect solution (100% bullet proof) to protect your JavaScript code on the client side, however there are some tools on the market that can help you to protect your code:
Code Compression/Minification (Usually don't protect the code)
Google Closure (Free)
Uglify JS (Free)
Code Obfuscation/Compression/Minification
JScrambler (Paid, but is on my opinion the best one on the market)
Jasob (Paid)
Stunnix (Paid, it seems to be outdated)
Hope this answers your question!
I would like to implement/embed a notes area where people can write some notes on my website.
is this possible with some simple html script? And if yes, does someone know where to find?
Here you can see what I mean: http://bwmbroadcast.org/player/flash?stream=MP4BW489-3A.mp4
Any help would be appreciated.
Thanks
If i were you i would implement a HTML-5 local storage system, http://net.tutsplus.com/tutorials/html-css-techniques/building-persistant-sticky-notes-with-local-storage/
You cannot do this by simply using HTML+CSS.
You have several options:
Use a simple HTML form that submits data to the server and save the notes to a database (you can use PHP and MySQL for this). Form submission can happen through AJAX. This seems to be the right way to me.
Use Javascript and save the notes in a cookie (this way you do not tie it to a user but a browser, I don't recommend this)
Use benhowdle89's solution, you need Javascript for that too, and HTML5 local storage support is not in every browser right now (still, notes will be tied to the browser, so if I visit your site from a different computer/browser, I won't be able to access them).
UPDATE: If you don't want to store notes at all, and only want it for printing, you could check out contenteditable. No need for Javascript here. See: http://html5demos.com/contenteditable
I've come across an issue which unfortunately I can't seem to surpass, I'm also just a newborn to Ruby on rails unfortunately hence the number of questions
I am attempting to scrape a webpage such as the following:
http://www.yellowpages.com.mt/Malta/Grocers-Mini-Markets-Retail-In-Malta-Gozo.aspx
I would like to scrape The Addresses, Phones and URL of the next Page which in this case is
http://www.yellowpages.com.mt/Malta/Grocers-Mini-Markets-Retail-In-Malta-Gozo+Ismol.aspx
I've been trying just about anything i could think of but nothing seems to work due to them being set to invisible or so.
The Address is within an h3 tag but it does not appear to be scrap-able. I've been also looking into ScRUBYt from the following url http://www.rubyrailways.com/ajax-scraping-with-scrubyt-linkedin-google-analytics-yahoo-suggestions/, but i really cant seem to find heads or tails of how to apply them in this case.
I would really appreciate any pointers as this is an obstacle which i really need to surpass in order to move forward on my assignment. Thanks in advance for any help.
In the particular example you have given, the elements are not hidden, but loaded via ajax after the page load. So basically what you need is a http client which can run javascript (web browser?) to see those address and other contents.
If you want to really automate the process and scrape the data which is got through ajax or javascript, you can try selenium. Even though it is not developed for that purpose, it serves your needs.
I don't have an answer to your specific question, but I thought I'd point to Ryan Bates' Railscast episode on screen scraping with ruby: http://railscasts.com/episodes/173-screen-scraping-with-scrapi
He uses a library called scrAPI instead of ScRUBYt, since he couldn't get ScRUBYt working. scrAPI seems to be a bit easier maybe?
I hope this helps somewhat, good luck with your assignment! :)

There is a good script posted at the google group. It seems to extract address, etc. You may want to look at the code for the script page.txt.
