When designing webpages you have to identifiy the key colours of your colour scheme. And considering that the RGB colour palette consists of 16 Million colours (16,777,216 to be exact) this can be a tricky task!
Website such as www.colorpicker.com will help you get the colour code for your favourite colours!
When creating your HTML pages you will most likely use colour codes in HTML or even better in your CSS code.
Do you understand how hexadecimal colour codes work? If so you should be able to guess the colour codes for all of these colours without the need to look it up on the Internet.
8 of the Challenges listed in the 101 Computing Challenges book require you to use an RDBMS (Relational Database Management Software) which support the creation of multiple objects such as tables, queries, input forms and reports.
One of the most popular desktop database management system is Micrsoft Access which is perfectly fine to complete these challenges. It’s a very good tool to learn Relational Database concepts. However it is part of the Microsoft Office suite and is not free to download.
You can however consider a free alternative to Microsoft Access such as Apache OpenOffice Base. The Appache OppenOffice is an open source suite of applications similar in many ways to Microsoft Office. The main difference being that it is free to download. You can find out more about Apache OppenOffice Base by vistitin this webpage:

Scratch is a free programming language and online community where you can create your own interactive stories, video games, and animations. It provides a dynamic and visual approach to programming where learners can drag and drop scripting blocks to write their computer programs. It’s very popular in schools as it provides a very intuitive user interface and the ability to get started easily and to start creating complex algorithms quite quickly.
There are two options when using Scratch. You can either create an account online and use the web interface to create, save and share your games.
Alternatively you can download the desktop application (Scratch 1.4 or scratch 2.0 beta, though you may want to check their website as their might be an earlier version available by the time your read this book)

A text-editor will be required for you to type your code especially when writing HTML, CSS or Javascript code. Our recommendation is to use a free text editor such as Notepad++. There are other alternatives that would most likely be suitable. When choosing your text editor you should choose one that has at least the following features:
You can download Notepad++ for free on:
Though you can start writing and testing your own programs once you have installed Python, we would strongly recommend that you investigate installing a Python IDE (integrated Development Environment). There are several free Python IDEs available, but if you are not sure which one to choose from, we shall recommend PyScripter which is a free, open-source IDE. It will make it a lot easier to type your code (Syntax highlighting and checking as you type, indentation options…) and mainly to troubleshoot and debug your code using the built-in debugging tools (breakpoints, variables windows…).
You can download PyScripter for free:
