BitMessage

BitMessage a Secure email Client and Server

Introduction

Bitmessage is a P2P communications protocol used to send encrypted messages to another person or to many subscribers. It is decentralized and trustless, meaning that you need-not inherently trust any entities like root certificate authorities. It uses strong authentication which means that the sender of a message cannot be spoofed, and it aims to hide "non-content" data, like the sender and receiver of messages, from passive eavesdroppers like those running warrantless wiretapping programs.

Boolean algebra

Brief introduction to Boolean algebra (or propositional Logic)

When writing conditional statements, such as if (condition) { ... } else {... }, its helpful to have a basic understanding of the laws of logic (or more formally Boolean algebra) that connect conditional statements together. These can be described by the operation of just 3 connectives, They are

Array data structure

Javascript Array Object

An array is a data structure common to all modern programming languages. Arrays are temporary data structures, that is they only exist so long as the program is running. Once the program is terminated any data contained in an array is lost. To use the built in Array object you must first create an instance of it using the new keyword.

Javascrtipt - creating a TOC

Problem specification - Adding a Table of Contents.

The aim is to be able to show a complete novice to HTML, how to add a Table of Contents (TOC) to a page inside a pair of div tag (with id="toc") provided for this purpose. Initially the TOC should list all H3 headers. and each item in the TOC must include a hypertext link to the relevant (h3) paragraph. Then having established a procedure, to use javascript to achieve the same result automatically.

Extended javascript projects

Programming projects (or extended programming examples)

There is no single path to learning any programming language, Sure there are some basic concepts you need to get out of the way first, but after that you learn the bits that are relevant to the current problem.
