Reading a friends blog post, I found out about a challenge for making a web app in 140 characters or less.
In Wikipedia you read:
In software engineering, a web application or webapp is an application that is accessed via web browser over a network such as the Internet or an intranet. It is also a computer software application that is coded in a browser-supported language (such as HTML, JavaScript, Java, etc.) and reliant on a common web browser to render the application executable.
So this is what I could come up with: just paste the following piece of code (140 characters) in a file with a .html extension, open it with a browser and you have a crude number guessing game:
<script>function
x(){if(confirm("odd?")&&((Math.floor(Math.random()*10))%2))alert(":)");else
alert(":(");if(confirm("rpt?"))x()}x()</script>
The browser calculates a random integer and asks you if it is an odd numbers. If your answer is correct it returns a smiley (or a frown if you’ve guessed wrong). Finally it asks you if you want to repeat the game and if you choose “ok” the whole thing starts over again.
You can save many characters by omitting the loop. Also you can save 10 whole characters by having the browser randomly choose “1” or “0” and asks you to guess between them.
<script>function x(){if(confirm(“1?”)&&(Math.round(Math.random())))alert(“:)”);else alert(“:(“);if(confirm(“rpt?”))x()}x()</script>

Nice one Dionysi
Have a look at my (not very interactive) entry: http://blog.cherouvim.com/re-the-140-character-webapp-challenge/
Just found your code on the webapp challenge. I just liked to point out that your 132 chars 1 or 0 game could have been wayyy shorter.
For example Math.Floor(…) is pointless since “>0.5” would have done the trick with 5 less characters.
So a shorter version of this could look like this (hope the blog won’t screw it):
a=confirm;while(1){alert(a(‘1?’)&&Math.random()>0.5?’:)’:’:(‘);if(!a(‘rpt?’))break}
