Detect and Inspect These three instructions are useful to decide what or if there is a block near the turtle. The detect command detects if there is an existing block ahead, up or below the turtle. If there is not, the turtle can move. Else, you may use the dig command to destroy the block. […]
To program a turtle is an awesome way to learn the fundamental concepts of programming while playing your favorite game. You will need a mining turtle and a remote control. To craft a turtle, you will need 7 iron ingots, 1 computer and 1 chest: To turn your turtle to a mining turtle you will […]
What ComputerCraft is about? It is a mod you can download and install Mods (short for modifications) are anything that changes Minecraft’s game content from what it originally was. ComputerCraft adds computers that you can program in Lua Lua is a powerful, efficient, lightweight, embeddable scripting language. “Lua” (pronounced LOO-ah) means “Moon” in Portuguese. As […]
A string is a set of characters. Letters, numbers or symbols inside quotes form a string. We may use single or double quotes around a string: “Hello world.” ‘Hello world.’ Both of the above values are strings. String is a sequence A string is a sequence of characters. We can access the characters using their index. […]
In this lesson, we are introduced to the concept of a variable. A variable is a location in a computer’s memory where we can hold information used by our program – just like storing things in a box. Each storage location in memory (i.e. variable) has three features: i. Name The name of a variable […]

A graph is a useful data structure in Computer Science as it consists of a set of nodes connected to each other with vertices. A pair of nodes is an edge (line if the graph is undirected, arrow if the graph is directed). Christos KatsoulasComputer Science teacher katsoulas.info
Scratch is a visual programming environment (drag and drop blocks like lego snapped together to create a script). The key idea of Scratch is to focus on projects instead of puzzles (like code.org). Children become familiarized with the process of transforming an idea to a program. Kids learn how to deal with challenges, how to […]
By Ian Watson. In 1936, whilst studying for his Ph.D. at Princeton University, the English mathematician Alan Turing published a paper, “On Computable Numbers, with an application to the Entscheidungsproblem,” which became the foundation of computer science. In it Turing presented a theoretical machine that could solve any problem that could be described by simple […]
Recursion is a method where the solution to a problem depends on solutions to smaller instances of the same problem or, in other words, a programming technique in which a function can call itself to solve a problem. Christos KatsoulasComputer Science teacher katsoulas.info
