How do I go about either making, or retrieving facebook short url's (fb.me) from a page, profile, event etc? I want to update my url shortener site - but if the user links to a facebook page I want to just return a fb.me link instead. Does facebook make their short urls on the fly, or does each page automatically already have one?
Facebook uses Bit.ly's services to shorten links from their site. While pages that have a username turns into "fb.me/<username>", other links associated with Facebook turns into "on.fb.me/*****". To you use the on.fb.me service, just use your Bit.ly account. Note that if you change the default link shortener on your Bit.ly account to j.mp from bit.ly this service won't work.
You can use bit.ly api to create facebook short urls find the documentation here
http://api.bitly.com
I'm not aware of any way to programmatically create these URLs, but the existing username space (www.facebook.com/something) works on fb.me also (e.g. http://fb.me/facebook )

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 just found out about Facebook Offers, which seem pretty interesting. I know how to create one, my question is, once created, does it have a permanent link? I want to link to this Facebook Offer from a link inside my blog.
Thanks
Themos
Yes, it creates a permanent link.
As an example, here's a permanent link to a Facebook Offer by a bagel shop.
When you create an offer it does get a permanent serialized link that you can share outside of Facebook (hence the Sharing utility). According to this Facebook documentation you can stop an offer and the link will still be available/visible but no one can claim the offer. You can delete the offer and the permanent link will most likely 404.

For more information and a detailed look at Facebook Offers I found this blog entry helpful.

I'm looking for an authoritative source on which browsers people browse facebook with. Specifically, I'm curious what percent IE6 and IE7 are at.
I constantly run into issues with IE7 on Facebook, and am trying to determine if it's worth my time to search for solutions.
I doubt if Facebook would release that private information.
You could use your own web server's log files (the server that hosts your facebook app) and get stats from those files. But I presume, you don't have access to those. So you might be able to make a guess by checking out the global stats here: http://www.w3counter.com/globalstats.php or http://www.w3schools.com/browsers/browsers_stats.asp
EDIT
Some information from a hosting company about its Facebook stats. However, this information is from 2009. :|
https://www.facebook.com/note.php?note_id=94523840758
Facebook has announced they are dropping support for IE7 (they already no longer support IE6). They have not announced numbers as far as I know. I doubt it will be worth it for you to support it as well for your Facebook app.

This morning dynamically generated links to FB pages from our app stopped working. Link to a page like this http://www.facebook.com/pages/125567350861413 used to work just fine, now it requires page name http://www.facebook.com/pages/Daniels-Real-Estate/125567350861413
Why would this be changed? Was there a problem with old pages link format?
We tweaked our code to take into account page name and made it work. But if a user changes the name of a page the link to this page will break, until we refresh the list of pages in our db. We'll write a chron job that will refresh the list of page names for all users using our app multiple times a day, but we'd prefer not having to do that.
Anyone else ran into this issue? What was your workaround (other than the above)?
While this is probably an off-topic question, you can get the page url using the graph api:
http://graph.facebook.com/125567350861413 and looking at the link property. As to why Facebook changed this, you would have to ask them at their developer group or log a bug.

I browsed a blog which allows you to comment on blog posts using facebook (piehead.com, if you want to see what I am talking about)
I noticed at the bottom that my facebook profile picture and full name were on the "add comment" section, since I am logged into facebook using this browser in another tab.
My question - does this site know that I visited, even if I don't comment/interact? Does the developer of the site have any knowledge of the information in the facebook comment "plugin"?
Thanks
Simple answer. No, your data is "protected".
Advanced answer:
Facebook comments are realised using xfbml. The Facebook libraries do not offer a way to know any data about you without your interaction with the plugin.
They will most likely not do in the future as well. You can read about that in the facebook plicies.
From an evil webmasters perspective who is interested in your data or identities of people visiting his site, the first thought would probably be:
This facebook thingy is loaded by javascript, right? So I should be able to access the webpages dom and steal the data?
The answer is no. Facebook is taking precautions for that. The javascript libary loads an iframe where your data is displayed, but that is isolated from the rest by javascript same origin policiy.
There are some some Cross site scripting workarounds in place (they are based on the only shared variable across documents loaded from different domains. Its the location variable), and there may of course be some security holes. There indeed have been discovered some in the early days, but the connect library is open source, reviewed a thousand times and can be considered pretty safe.
There is however one "security hole" that enables a webmaster to tell whether you are logged in to facebook or at least take a good guess. But no information about your identity would be present. It would only be possible to cross reference you as a visitor and gain this knowledge about you. You can read about that here.
