I was doing some small modification to Trainque’s Twitter Badge when I encounter this error message in Firebug:

Apparently this is a limit for API invocation. Does this mean if a website with twitter badge is visited by more than 100 people per hour, only the first 100 people will see the twitter badge content? After reading this documentation, I finally understand the meaning of this limitation. It means that an IP address cannot request more than 100 API requests per hour. Other way of saying this is, if you keep on refreshing this page for 100 times within 1 hour, you will not be able to see the Twitter Badge content on your 101st refresh. You need to wait until the next hour before you able to see the Twitter Badge Content.

I need to have a good regex for URL validation in javascript. After googling a number of websites, blogs and forums. The best I found is this blog post by Ivan Porto Carrero

I modified it a bit to make it valid in Javascript as shown below:

twitTxt = twitTxt.replace(/((ht|f)tp(s?)\:\/\/|~\/|\/)?(\w+:\w+@)?(([-\w]+\.)+(com|org|net|gov|mil|biz|info|mobi|name|aero|jobs|museum|travel|[a-z]{2}))(:[\d]{1,5})?(((\/([-\w~!$+|.,=]|%[a-f\d]{2})+)+|\/)+|\?|#)?((\?([-\w~!$+|.,*:]|%[a-f\d{2}])+=([-\w~!$+|.,*:=]|%[a-f\d]{2})*)(&([-\w~!$+|.,*:]|%[a-f\d{2}])+=([-\w~!$+|.,*:=]|%[a-f\d]{2})*)*)*(#([-\w~!$+|.,*:=]|%[a-f\d]{2})*)?/, twitRegexCallback);

If you like it, a link back/comments would be much much appreciated 🙂

It’s something that we need to always remember, that we are as human, is really really nothing in this universe.
