Practical Activites

Simple Crypto

I knew there was something about the position of the numbers 3 4 4 1. I couldn’t figure it out what it was. My friend hinted me to read them in columns. Putting the 3 4 4 1 into columns allowed me to realise how to solve the crypto. I put each text separated by space underneath the previous and from there I read the flag from the first column to the next.

Shredding Analysis

What I looked at was the author’s name, and the headline (each word began with capital letters). 

Dumpster Dive

There was a lot of information on the tags and receipts.

Coincidence Index

Wax on had less coincidence than wax off. My conclusion was that the wax off text is the mono-alphabetic substitution cipher and/or transposition cipher.

Life expectancy of a computer connected to the internet

From research, it is on average about 3-5 years. From secondhand experience, it would be about 3 years before it is replaced. My first laptop is the one I bought since my first year of uni and I am still using it, and it seems to still function just fine.
