From organized hackers to govermental spying

Recently, the news has been flooded by messages such as “Anonymous attacks governmental websites” or “Hackers leaked sensitive information”.

The beautiful mountainous country being targeted by criminal hackers? well it looks like it!

Steve Jobs passed away

I still remember when i got my first Mac in the year 2005. I was like most of the readers of my blog interested into new technology stuff. My mac was a iBook G4 which was a blast, I just loved it. Then as the new Macbooks and Macbook Pro’s came around i got more and more into Apple Computers. Apple products are easy to use and they are a part of history, especially the mobile technology and music industry.

Buffer Overflow explained

What is a Buffer Overflow?

To put it simple, it is putting too much information into a limited space. For example you declare a buffer with 8 elements in it. Now a buffer overflow would be to fill the 8-byte element buffer with 65 bytes. The problem here is that the rest 57 elements will overwrite the neigbouring memory cells. This comes particularly bad if the neigbouring memory cells are cells reserved by the operating system. If that happens then the Computer either crashes or hackers can gain higher privileges, depending on which memory area is accessed.

Storing negative numbers as binary

As a programmer and computer enthusiast it is very helpful to know how numbers are stored in memory, also known as RAM. Well everybody knows that information is stored as a stream of binary digits known as Bits, that are made up of 1s and 0s. 8 of those bits build a Byte. One number type is called a Whole number, or Integer in computer terms. Those can be negative and positive, or in other words signed and unsigned respectively. Now comes the question of how to store those numbers effectively? This is what I will show you in this blog.
