Exercising Python

2007-02-19T09:00:00.000+08:00

I was bored and wrote a Python script to play around with Smashpop's pimping shoutbox, using httplib.

import sys, httplib, time

def pimp(count):

body = "name=Yuen-Chi+Lian&email=yuenqi%40hotmail.com&url=http%3A%2F%2Fyuenqi.blogspot.com%2F&submit=Publish&user=smashpop&comment=smashpOp_Pimps_You_3&addMessage=pimp+http%3A%2F%2Fyuenqi.blogspot.com%0D%0A%0D%0A%20%28" +str(count)+ "%29"

requestor = httplib.HTTP("www.haloscan.com")
requestor.putrequest("POST", "/comments/smashpop/smashpOp_Pimps_You_3/")
requestor.putheader("Host", "www.haloscan.com")

#requestor.putheader("User-Agent", "Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.8.1.1) Gecko/20060601 Firefox/2.0.0.1 (Ubuntu-edgy)")
requestor.putheader("Accept", "text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5")
requestor.putheader("Accept-Language", "en-us,en;q=0.5")
#requestor.putheader("Accept-Encoding", "gzip,deflate")
requestor.putheader("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7")

requestor.putheader("Keep-Alive", "300")
requestor.putheader("Connection", "keep-alive")
requestor.putheader("Cookie", "name_cookie=Yuen-Chi+Lian; email_cookie=yuenqi%40hotmail.com; url_cookie=http%3A%2F%2Fyuenqi.blogspot.com%2F")
requestor.putheader("Content-Type", "application/x-www-form-urlencoded")
requestor.putheader("Content-Length", str(len(body)))
#requestor.putheader("X-Requested-With", "XMLHttpRequest")
requestor.endheaders()
requestor.send(body)

(status_code, message, reply_headers) = requestor.getreply()
reply_body = requestor.getfile().read()

print "status code:", status_code
print "status message:", message
print "HTTP reply body:\n", reply_body

count = 7
while True:

pimp(count)
count = count+1
print "---- Going for Next round ("+str(count)+") ----"
time.sleep(35)

The script tries to replay the action of posting a comment in the shoutbox, but it couldn't work, probably due to some environmental (user agent) problem.

Writing a HTML/Javascript hack is easier:

<html>
  <head>
    <title>control</title>
    <script type="text/javascript">
hD="0123456789ABCDEF";

function d2h(d) {
  var h = hD.substr(d&15,1);
  while(d>15) {d>>=4;h=hD.substr(d&15,1)+h;}
  return h;
}

globalCount = 39;

function pimpInit(){
  parent.frames[0].location = "view.html";
}

function pimp(){

  var count = globalCount;
  parent.frames[0].document.forms[0].elements["addMessage"].value = "pimp: http://yuenqi.blogspot.com\n\n(h: "+d2h(count)+")";
  parent.frames[0].document.forms[0].submit();

  globalCount = count + 1;

  var elem = document.getElementById("pimpHistory");
  elem.innerHTML = elem.innerHTML + "<br/>Pimping: " + globalCount;

  setTimeout("pimpInit()", "35000");
  setTimeout("pimp()", "36000");
}
    </script>
  </head>
  <body>
    <div id="pimpHistory"/>
    <script type="text/javascript">
pimp();
    </script>
  </body>
</html>

Meh!

Happy 5th Birthday JXTA

2006-04-26T10:36:00.000+08:00

I have not been blogging here since I started looking for job. I am currently working as a Java Developer for a company named Customware.

Anyway, today is JXTA's 5th Birthday, I did not know until I read Stephanie Kaul's message posted in the mailing list. I spent two years time in JXTA previously, one was to build an online marketplace, another one was to build a p2p social network. Right now, the reconstruction of the latter one is still running, although I can't really dedicate my time on it as I am busy in company's projects at this moment.

The latest JXTA releases are:

Get started now. (:

Java Platform, Enterpriser Edition 5 (Java EE 5)

2006-02-21T11:02:00.000+08:00

Java 2 Platform, Enterprise Edition (J2EE) is a powerful and widely used enterprise solution, used to develop and run distributed multi-tier architecture applications. The latest version of it, Java EE 5, which Sun introduced not very long ago in their website, provides more robustness and scalability, hightlights, taken directly from the site,

Easier development. The focus in Java EE 5 is ease of development. With Java EE 5, there is less code to write -- much of the boilerplate code has been removed, defaults are used whenever possible, and annotations are used extensively to reduce the need for deployment descriptors.
EJB -- simpler, better. EJB 3.0 makes programming with Enterprise JavaBeans technology simpler through the use of Plain Old Java Objects (POJOs), it also introduces a new persistence API.
Enhanced web services. Java EE 5 includes simplified web services support and the latest web services APIs, making it an ideal implementation platform for Service-Oriented Architectures (SOA).
JSF, JSTL, AJAX, and more. Constructing web applications is made easier with JavaServer Faces (JSF) technology and the JSP Standard Tag Library (JSTL). Java EE 5 supports rich thin-client technologies such as AJAX, technologies that are crucial for building applications for Web 2.0.

I am quite familiar with J2EE's architecture although I haven't really gone through a full SDLC which involves EJB, JNDI, XML-RPC, etc. While I am training myself in C++ recently, I hope I can spend some time to explore JEE5.

Gaim 2.0.0 Beta 2

2006-01-29T00:29:00.000+08:00

I hope I am not too late to blog about this. I have been experiencing instability such as sudden-crash in Gaim 2.0.0 Beta 1, waited for it to release and finally they did it on Tuesday, January 24th 2006.

Note: Gaim is a multi-protocol instant messaging (IM) for various operating systems.

Basically it is just a sequel with some minor bug fixes. Have not really tried it out as I am quite busy lately, and most of the time on Windows Live Messenger Beta 8.0. (I like how Beta 1 supports custom emoticons, but I just could not stand the impotence!)

At the time of writing, I am still working on this blog. I might have to stop it a while as I am developing a decision-maker for UltraUnix and would like to spend more time on it.

Anyway, happy chinese new year to whoever celebrate it!
