Circular Links in You Twitter/Facebook updates

Say you want to insert a link for your tweet inside that same tweet, or want to link a facebook update inside the update itself. The issue with this is that: first you can’t know what will be the link to your new tweet/update, and second, once you post something on these sites you can’t change it (unlike Google Buzz for example).

I am used to celebrate my tweets which rank is of the form xxxx where 0<x<10 (I expect some technical knowledge for my reader :p), for example my 1111th and 6666th tweet, and usually the form of the tweet was :

wohoo, my xxxxth tweet [and a link to this same tweet here]

The idea was to use a link shortening service and do the following, we can use bit.ly

  • Check if the url http://bit.ly/WHAT_EVER_YOU_WANT_HERE is not already taken, by typing it into the browser and checking that a Page Not Found error occurred which means the suffix WHAT_EVER_YOU_WANT_HERE is available.
  • post your tweet/update with the above link.
  • then take the link of the new tweet/update, shorten it with bit.ly and custom the shortened url using the same suffix of the link above.

And by doing this, you finally have a circular link, targeting the same tweet/update which contains the same link targeting the same… you get the point.

Here is an example of a tweet:

Pictures on Social Networks are Going to Stay Forever

If you have ever uploaded a picture on a social media network like Facebook or photo sharing services like Twitpic and Flickr then wanted to delete them, this might be a big trouble for you.

I figured out today that deleting a picture from Facebook makes it disappear from their website (the link doesn’t of the picture show up anymore) but not really from their servers, and a small research on the web shows that this is not new, it has been showed that pictures deleted from Facebook, MySpace etc are not always deleted right away, and actually their Facebook picture is still online after more than a year now without disappearing from the Facebook servers.

For testing purposes I tried deleting pictures from Facebook, Picasa and Twitpic, only Twitpic has deleted the photo after few minutes, the other two are still here.

This means that some time in the future we might be able to search for persons by their (deleted) pictures on such website, while services like these are already working pretty well like idée TinyEye which indexes pictures using their links, it won’t be strange for facebook to start new privacy settings that allow such services to index even the so called deleted pictures.

The moral of the hole story is, if you are to upload any picture on the web, make sure to use services that gives you control even over your physical pictures or at least provide temporary links that expires after some period of time like Flickr and Twitpic.
