What Paypal doesn’t tell you?

Filed under: Interesting — Rohit Aggarwal @ 12:13 am

This post is to explain the pseudo assurance that eBay or Paypal gives you.

“Pay with  and your full purchase price is covered |See terms

You see the above assurance on ebay and felt safe to purchase an item. You wait for many days but your item never arrives. Getting apprehensive you try reaching out to the seller. He never responds to your messages. After getting frustrated you test the above statement and later gets pointed to the following policy.

What if PayPal makes a final decision in my favor?
If PayPal makes a final decision in your favor, we will collect any available funds in the seller’s PayPal balance
at that time. However, recovery is not guaranteed and is limited only to the amounts that PayPal can recover from the seller’s Account. Any amounts collected from the seller will be placed in your Account.

The point is that in case a seller commits fraud and never sends you the item, you can not do much about it. Fraudulent sellers are not going to leave any money in their Paypal account. So ebay and Paypal will only apologize to you and you will not get any dime back. :-(

I don’t recommend using debit card for paying an eBay purchase. With credit card hopefully you can still file a chargeback against Paypal and get your money back.

jQuery Calendar date time picker

Filed under: Web Applications (IS 4460) — Rohit Aggarwal @ 3:08 pm

I came across this very cool jQuery based date time picker. There were some bugs initially in this code, but the owner of this blog (Dan) is a very helpful person.  On my request he fixed the issues and sent me the updated code. 

I have tested it on IE, Firefox, Chrome and Opera, and it works on all.  For trying this awesome date-time picker click here

Here is the picture of this picker:

VPN client for University of Utah

Filed under: Teaching — Rohit Aggarwal @ 4:17 am

If you are looking for a VPN client for University of Utah then the link is here and the details on that page are:

The VPN client software is available at no cost for the following operating systems:

Pick the client according to your system and enjoy the online books at Safari. You will need your university ID and password to download the client.  I would have liked to download the clients and give direct links to my students; but that would have violated University policy because even the download is password protected.

 

An alternative solution to access library’s databases are:

https://tproxy01.lib.utah.edu/login

UNID ID and password.

Hi!

You can find the Course Syllabus here. Please try to keep up with the reading and work out examples regularly. If you will not work regularly then it will be hard to catchup with the class later. 

I will make sure that at the end of the class you are comfortable in making web applications such as a simple online review site.
