Challenge 2

On the second installment of this reverse engineering series I present you with a new challenge. This time you are a secret agent, and you are on a very important mission. Some documents are stored on a locked safe that you have to open. There are some weird symbols and some green bars that oscillate up and down. Your intuition tells you that the safe will open when the three bars are full!

Now you start to think… this is the way, but how I am gonna make it happen?

If you decide to go and solve this challenge, please, tell me how you did it on an email (david@studiosi.es) and I will collect the solutions on a future post. Even better, do a write up, post it somewhere online and I will link to it here!

Challenge 1

This is the first of a series of reverse engineering challenges that I am going to craft for this blog. This one should be easy, with a little bit of patience I am pretty sure that you can get the flag stored inside the file.

Web systems, a definition

In this article I am to define as deep as possible what is a web system and establish a taxonomy that allows a proper classification of said systems. These categories can potentially define factors that affect the complexity of the system itself and define the nature of these systems.

Introduction to Software project effort estimation using function points

This is the first of a series of articles in which I am going to dig deep into the discipline of software engineering and more specifically software measurement: why small entities can benefit from it, how this methods can be applied in practice in a cost-effective way to increase the profitability of software projects and how managers can use them to make better offers to their clients.
