Currency Conversion With foxrate.org's XML-RPC API

Foxrate.org provides XML-RPC API to convert the currency from one to another. I needed it for a project to convert from Euro to Pound and vice-versa. I had once read about such a work in roshanbh.com.np so I finally thought to follow the same API. After searching for some days, I came up with some code but had some problem for which I couldn't get any help. At last our senior friend from college, Sanjeev, added last two lines of code to make it run. Thanks Sanjeev.

Facebook is hit by a fast moving Social Engineering Attack

November 2008 is going to be a bad month for Facebook as a rapid moving chunk of malware is working through the social community, and sending an email with a link that sends a person to a compromised site, with the extra side bonus of malware. This though seems more like a social engineering style attack rather than a true worm/virus although it has components of each as part of its makeup. Essentially the user still has to do something, so it is not wholly automated. The way this works though… Continue

How long can a developer survive without Google?

How many times did your boss come up with "can we do X?" and you didn't have a clue about it but answered "Yes, no probs at all - consider it done"? You were probably thinking "WTF - I have no idea about this", and first thing you do when you're back and safe at your desk is googling the damn thing up. We can do stuff like that only because developers are merging into a collective intelligence through internet + Google. Mortality rate (= getting the axe = being let go = being fired) would be dr… Continue
