Do you know PayU? It is a Paypal competitor on emerging markets. A few weeks ago I was talking with my friend, who was working on online payment integration with PayU REST API. He showed me that you can play around with payment details and PayU API won’t complain about amount not mathematically correct. It is possible, that client will increase products quantity without increasing the amount to pay. I invested some time to test all the cases and this article will show you how to hack PayU payments and to get more than you paid for.

I don’t know about you, but i get lots of e-mail everyday. I mean LOTS. Some of them are short reminders that reside in my inbox for days to actually remind me of something. If I could choose, I would prefer to receive reminding SMS. It’s more interruptive, but reminders should work this way :)

In every application, that store user data, you have “name” field. It’s often divided into first and last name. Such architecture helps with sorting (using last name) and it’s convenient for programmers (we LOVE tables, don’t we?). I’ll try to answer question: is first/last name good global design choice? What would be user experience all over the world? Do everybody have last name?
Back to 2005 I had no idea what is character encoding, why I see � in text files or what is the difference between Unicode and UTF-8. It looked so complicated, that I felt like a blind man every time I needed to deal with this. In this article you will learn all nuances of encodings, why UTF-8 had become standard and how they call unreadable characters in Japan.
