Random Library Challenges
In this blog post we will experiment using some of the key functions from the random library. Many Python games will involve some degree of “randomness” for the game to be more realistic and unpredictable. Flipping a coin, throwing a…
DOS Emulator using Python
In the 1980’s, when IBM introduced the IBM PC which was built with the Intel 8088 microprocessor, they needed an operating system. They approached Microsoft who provided IBM with the “Microsoft Disk Operating System”: MS-DOS. A Disk Operating System is…
4-bit counter using D-Type flip-flop circuits
In this blog post we will design an electronic circuit using logics gates (combined into D-Type flip-flop circuits) to create a 4-bit binary counter. This approach will help us understand how a program counter may be designed within the CPU…
Solving a Murder Mystery using Prolog
In the middle of last winter, eight guests were invited to a luxurious retreat at the Duke of York Grand Hotel. On the last day of their three-day getaway, the guests were free to vacate to their own occupations. Mrs…
OOP Programming: Classes & Objects
In this blog post we will investigate how to create some basic classes and objects that could be used in a range of programming projects. Classes and Objects are the building blocks of Object-Oriented programs. You can find out about…
Bubble Sort Algorithm in LMC
The aim of this challenge is to implement a Bubble sort algorithm on a list of 10 values using LMC. We will be using our online LMC simulator to test our code online LMC simulator: Executing the Code We will…
Memory Filler in LMC
The aim of this challenge is to write a program in LMC that will fill in the memory/RAM with the value 999, from memory location 50 onwards (up to memory location 99). Note that even though such a program may…
Self-modifying code in LMC
In computer science, self-modifying code is code that alters its own instructions while it is executing. Getting code that overwrites itself can seem dubious, rather risky and hence unrecommended. However in some cases, it is a technique that can be…
Drone Display
Drone displays/light shows are performed by synchronized and choreographed collections of drones that position themselves to recreate various aerial formations. Each drone is equipped with LED lights that can change colour during the display. The first drone display was presented…
