I need to figure out the time for which an email remains open at the recipient's end.
I can use a 1x1 image to find out if the email has been opened but i can't think of any way in which that would allow me to calculate the time for which the email remains open
Thanks for any help.

This isn't possible.
The closest you can get is by having an image never load. That is, you accept the connection on the server, send the response headers, but don't send any data. The client will disconnect once the e-mail is closed. However, this is extremely problematic. Some clients will never disconnect. Others will timeout. In addition, you have the problem that many won't open the image at all. Finally, this will break many up-stream proxies.

Besides what Brad mentions, the only other I can think to calculate time data is if they click a link in your email. You could track the time between image load (open) and click to give you some engagement data. This would obviously only return results for users who both turn on images and click a link however.
I know Litmus has engagement tracking in their analytics, not sure which technique they use to produce their results, but they only track up to 12-18 seconds.

2 days ago i got a https request from facebook.
Now i am getting wierd notifications when some one message me on facebook.
I am pretty sure this is ilegal.
I gave no permission also i dit not read any thing about it.
And i want it gone, can any one help me?
It is not showing anywhere, not in chrome://plugins chrome://settings or windows programs.
i dont have time to search for it and get nowhere...
if some one has the knowledge of this installation please respond, many thanks.
Regards.
Maybe you are confusing (one of the new features of FB) desktop notifications with something.
Firstly, its not illegal.
Secondly, I'm very sure that you have allowed it yourself.
How to remove it:
Open facebook.
Click on the lock in the address bar (where you type the url). You should see the lock before https:// (from where url starts).
You can see the Permissions tab there, which should show:
Notifications: Allowed by you.
Click on it and disable it.

I am very confused by Paypal's site. Does anyone have any direction on how to setup Paypal knowing the following information?
I need users to be able to invoice and use credit cards.
There will be a value that is unknown until the time of checkout.
With Paypal, they want to see certain POST variables to know who you are, how much is being charged, if there is tax etc... In the past, I have just written some javascript functions to adjust these values before they are submitted.
For example, here is the paypal documentation. https://www.paypal.com/us/cgi-bin/webscr?cmd=_pdn_xclick_techview_outside
Creating a javascript function to change value="12.99" to value="Whatever" before the user clicks the Pay Now button is one way to do it.
Knowing more about how this value is created etc, would determine how the javascript (or JQuery) function looks.

We've received an automated message "Our systems have flagged your app <> for receiving a high amount of negative user feedback. Accordingly, we might be forced to place a temporary restriction on your app in order to protect the user experience on Platform. We ask you to promptly address this issue within 48 hours of the sending of this notice, after which our automated systems will evaluate your app once again. Please note we reserve the right to take action against your app even before the end of this 48 hour period.
Specifically, users are responding negatively to Stream stories from their friends using your app."
We're struggling to triage and rectify this ASAP. We're not aware of any engineering change that would introduce an issue and we manage a news-style website from which a user can share any number of stories. BUT we can't find anything in insight that gives us an idea if a specific story was shared and is the root cause of being reported as spam.
IS anybody aware of how one might "drill down" within insight and get down to the metadata regarding the specific posts being flagged/reported?

This is not a problem with your app..
This happens sometimes because your app server might have taken a longer time to update on FB servers and the connection timed out...
Nothing to worry about you an try again
I had the same issue and solved it by checking all the icons and screenshots. I made sure that they all was in the same format (.png) and then it worked!
I guess the issue, for me, is that i used different formats.

I'm trying to enable some basic commands via email. Currently I have shared hosting accounts with shell access at dreamhost and site5. I usually use php/drupal, but am open to other options. I found this question, but I'm looking for something more basic: what do I need to configure where to create a hello world app that responds to email? Are there (free) services out there that will make the basic set up easier? I'm pretty open to using any kind of email address, since this is for a personal project at the moment....
For email, it would be pretty easy to setup a cron job that pulls in email via POP3, then loops through and responds to them.
For example, you could do it with a Python script using the poplib (http://docs.python.org/library/poplib.html) library. Then just have cron call your script every 5 minutes.
I have no affiliation with this company, but Twilio (http://www.twilio.com/sms) provides services and a simple API for a lot of this sort of thing. I've never used it, but it looks like the answer to many people's prayers, so well done them.
