I am trying to develop a web based document browsing system, that could look possibly something like : http://www.cell.com/trends/biochemical-sciences (then click on "Protein kinases: evolution of dynamic regulatory proteins").
What web technologies should I look at using? AJAX?
Thanks in advance.
Andy
AJAX could do the trick, but you'll need more than that.
Getting document sections and pictures with AJAX is half (maybe less than half) the job, as you'll need all the backend code to upload documents, maybe extract document sections from PDF, store documents hierarchically, retrieve the document hierarchy and pictures, and so on.
Moreover, you don't even told us what server-side technology you are going to use... Java, PHP, DotNet... and the database... PostgreSQL, MySQL, SQL Server, Oracle, end the list goes on.
About the AJAX side and web UI, I suggest you take a look at jQuery and jQuery UI.

Ours is a java web application on struts2 framework. Currently for contact us form and download reports form we are using Recaptcha. We have to refresh the captcha at least 4-5 times to get the readable words. We are looking for some simple alternative to Recaptcha which prevents getting Spam requests.
Guys can you suggest me a replacement for Recaptcha.
Yes, another example of an alternate captcha is this: you can make a slide of images, and place one behind the slider. Then, let the human chose from the slider which image is behind the slider.
(I have seen it in a forum, but I don't remember the name of website where I have seen this type of captcha)
You can also make your forum like no one can copy paste anything there, means pasting is restricted there.
I found this! http://areyouahuman.com/
Just discovered it. Plan to use on my next project.
Images are far more easy to identify compared to garbled text. They are more difficult to break too. You could use image-identification CAPTCHAs such as these.

I was preparing for the interview and I stumble across this question.
Can anyone explain me what are the Benefits of Ajax Calls,
why do we need Ajax Calls and what can be the disadvantages of Ajax.
Any suggestions will be appreciated.
Most importantly, do you understand what AJAX is? If not, I would start by reading through http://en.wikipedia.org/wiki/Ajax_%28programming%29 .
One large benefit is that it allows for partial updates to pages, without requiring a reload of the current page or a load of a whole new page with each action or input, as was typical in years past.
One disadvantage may be some additional complexities, development time, and troubleshooting. (The above Wikipedia link actually contains a list of 10 drawbacks for "disadvantages".)
Ajax calls can help you decrease website load. for example if you want to load a customers table from database ajax can load it in without refreshing your css and images etc... so you can save memory by using ajax.
disadvantage of ajax is ... it's taking too much time in development and little bit hard for basic users

I know that there are lots to read on the net about AJAX , but if U want to explained it for a non-web-technical person what would you say ?
"A style of web page where you can edit stuff without having to wait for the whole page to reload all the time"
It's a mechanism to communicate with webserver (backend) without refreshing the whole page. :)
But I believe this site is not a good place to ask these kind of questions.
"A way of updating a web page in sections, instead of all at once."
It's a technology that allows you to download only select portions of the web page, providing a faster and less disruptive page update.
Prior to AJAX, if you need PEN, you must have to buy PAPER and other things which you already have.
In AJAX, you get what you need.
A technique which escape your server from extra burden and fasten your responses

I'm looking for a free UPC or Barcode database that is available for download. I have seen upcdataBase.com and a few others, but those do not allow for a free download of the db. File type is not a huge issue as I can work with SQL, csv, text, XML, json or anything else.
Anyone know where I can find one? I do not want a web service, I need an actual file or method of downloading all of the upcs or barcodes someone has. A large inclusive db would be great, but even a partial db would be great.
Thanks
Logical Solutions (http://www.LogicalSo.com) sells UPC barcode datamining software that scans the web for barcodes and product names, and build a database for you.
Gregg London sells UPC databases in the form of a "Product Load Service". There is more information on their site: http://www.glondon.com/upcdatabase.html
You probably can make a quick mashup using: searchupc.com and upcdata.info and then retrieve product information from google product API.
Also, you can use AWSECommerceService API to retrieve something like this:
ItemLookupRequest request = new ItemLookupRequest();
request.getResponseGroup().add("Large");
request.setIdType("UPC"); // TODO: need to change if it's EAC
request.getItemId().add(upc);
request.setSearchIndex("All");

I'm interested in information about changing ELMAH's UI. I know its possible, either through the ErrorLogPageFactory (not much info about it out there) or by rolling your own.
In short, I'm interested in the built-in facilities of ELMAH for skinning the report UI. Secondary is how to use ELMAH's API to roll your own UI (rather than the naive route where you write against sql or xml, depending on the storage provider your website uses currently).
Elmah has an ErrorLog.css file (inside the dll) that would be your source for skinning the report to your liking. I doubt it would be too hard to make that an external dependency. Further changes to the UI would likely require you messing with the source. It's good code, so that shouldn't be too hard.
The other item that I found interesting for pulling information from Elmah is that she (can I refer to software as an entity...) has an option for json output. The URL just tacks on a json element:
