Book Review: Computer Investigation by Elizabeth Bauchner

Who is the target audience for this book?

Make no mistake. This book is not targeted for computer professionals. If you have a degree in Computer Science or just know a lot about computers, you won’t learn anything from this book. This book is targeted to children in the middle school age group, but it would also be a good introductory book for adults.

That said, what does the book talk about?

What is the science of computer forensics?

Computer forensics is a two-part process. First, data is retrieved and then the data is used. It is different from other forensic sciences because the data usually stands on its own and does not need to be interpreted.

What are the many duties of a computer forensics technician?

While doing their job, computer forensic specialists must preserve evidence, not introduce viruses or worms into a system, handle data properly, keep evidence within the chain of command, reduce the impact of the system’s analysis on any businesses affected, and make sure privileged information is not divulged.

Following those rules, computer forensic professionals find hidden files, swap files, and temp files used by the operating system and by applications. They access these files and protected and encrypted files, searching for information relevant to the case. They analyze the data found, especially in areas normally considered inaccessible. They perform an over all system analysis and list all relevant files. They provide an opinion of the system’s layout and who authored which files. They make notes of attempts to delete or protect files, and they provide expert testimony and/or consultation in court as needed.

The book gives definitions for commonly used words, or jargon, in the industry.

A hacker is someone who is really interested in a piece of technology and learns all possible about the technology.

A cracker is someone who uses their hacker knowledge for bad.

Hackers are white hat, and crackers are black hat hackers.

A phreaker was a person who scammed the telephone company to get free long-distance calls.

Spoofing is mimicking a website (or an email) so the receiver thinks the sender is someone else.

Phishing is trying to get information from people, like their user accounts and passwords, and social security numbers.

A virus is a program, attached to another program, that infects a system when the program is opened. The virus can’t do anything unless the program is opened and ran.

A worm is like a virus, but it can replicate itself without other programs being opened.

A Trojan horse is a program that pretends to be a different kind of program.

Denial of Service (DoS) is when a cracker tries to prevent a system from being accessible by its normal users.

Review of ‘Invent Your Own Computer Games With Python’ by Al Sweigart

Nowadays, there are few books that serve the function of teaching programming, as well as providing fun, especially for the children. Al’s book serves both.

Basically, this book is about creating games with python but it also serves as a ground for ‘breaking the ice’ for those who think that programming is only for the ‘PC geeks’. According to Al, ‘Programming isn’t hard. But it is hard to find learning materials that teach you to do interesting things with programming. Other computer books go over many topics that most newbie coders don’t need. This book will teach you how to program your own computer games. You will learn a useful skill and have fun games to show for it!’

It allows readers to create an interactive game using python and late shift the skill up by using pygame to create animation and sound, a very important aspect of creating games.

Who is this book for?

Programming isn’t hard. But it is hard to find learning materials that teach you to do interesting things with programming. Other computer books go over many topics that most newbie coders don’t need. This book will teach you how to program your own computer games. You will learn a useful skill and have fun games to show for it! This book is for:

Complete beginners who want to teach themselves computer programming, even if they have no previous experience programming.

Kids and teenagers who want to learn computer programming by creating games. Kids as young as 9 or 10 years old should be able to follow along.

Adults and teachers who wish to teach others programming.

Anyone, young or old, who wants to learn how to program by learning a professional programming language.

There are 20 chapters in the book

A very notable aspect of this book is that, rather than normal programming books, which provide the principles first, then the application, Al`s book show the source code for games right up front and explain programming principles from the examples.

This book is not for making games with high tech graphics but for games good enough for attracting online gamers or as a game for mobile phones,as Al said,

‘The first few games we’ll create together in this book will probably seem simple compared to the games you’ve played on the Xbox, Playstation, or Wii. They don’t have fancy graphics or music but that’s because they’re meant to teach you the basics. They’re purposely simple so that we can focus on learning to program. Games don’t have to be complicated to be fun. Hangman, Tic Tac Toe, and making secret codes are simple to program but are also fun. It explains every aspect of python from installing it to using pygame for sound and animation. Overall, a good, sound and interactive method used throughout. Recommended for all age and programming levels.’
