**Theta8 – Next step website analysis**

I’m proudly present a new release of a project, that I’ve developed at the cip-labs. It’s named Theta8. This smart web application analyzes the response of a given URL and collects some data about it. It gives advices, tricks and tipps for the frontend optimization. Below, I will explain some functionality in more details: How it was built? Theta8 includes some PHP code and also some lines of C code. The core was programmed in PHP, but some functionality (e.g. network operation… continue reading

**Neuron based data structure – An implementation**

Exactly one year ago, I came out with an idea of a neuron based data structure. In the first article about this idea, I tried to give an overview about, how this data model should work. In the article below, I introduce you to the implementation of th…**Ipsum – The PHP formula parser**

Some time ago, I thought about that it would nice to have a smart piece of code, that calculates the result of a given formula. The next step, I thought about, was to integrate customized functions into the code. So, I wrote a parser, that is able to …**Benford Calculation in PHP**

Some month ago, I came out with an article about Benfords Law. This article deals with the summation and product formula based implementation in C. The algorithm is indeed cool for small statistical games, but not nice to use, when you have a set of n…**MySQL Schema Performance Considerations**

The most optimization tricks for MySQL focus on query performance or server tuning. But the optimization starts with the design of the database schema. When you forget to optimize the base of your database (the structure), then you will pay the price …**Ideas to bypass the frequency analysis**

In the history of encryption article, I even dealt with mono alphabetic substitution. This means, that every letter from the source alphabet will be substituted with exactly one letter from the target alphabet. It is simple to understand as it is easy…**The history of encryption part 1**

This article deals with the history of encryption and is the first part of two articles about this topic. All techniques were described in a chronological order. In this part of the article I deal with: Introduction Scytale and transposition cipher R…**Nondeterministic Finite Automata in PHP**

A few weeks ago, I wrote an article about an implementation of a DFA (deterministic finite automaton) in PHP. Today, I present a implementation for an automaton, that is not deterministic. It means, that the automaton have no, one or more than one edg…**Deterministic Finite Automaton in PHP**

An important area of the theoretical computer science deals with finite automata and languages. We use a finite automaton to detect words of regular languages. The types of grammars that create a language are defined in the CHOMSKY-hierachy (Noam Chom…**MySQL Server Optimization**

MySQL is a very powerful and popular database server for web applications. It’s a open source project with a big community. A lot of people deal with the performance of this server to make their applications faster on small machines. This articl…**MySQL Query Performance**

The scope of MySQL optimization is very wide. One aspect of this complex field is the query performance and this article deals with it. MySQL provides powerful tools, that allow you to have a look inside the query parser & optimizer. To understand…
