Language bootcamp

Need to learn a language for a course? Or, just looking to find out what a language is like? Look no further.

Hello world in 15(ish) languages (if applicable), with language best practices. These languages are supported by the CS Unix machines, unless otherwise stated.

Content of each (available where applicable)

• Fizzbuzz (if/else demo)
• Factorial done recursively
• Some string processing (see below)
• Object demo
• Loops and structures
• How to run it

if possible, discuss

• file i/o
• arguments

String example

The example shows:

• substring
• search
• index a letter
• split
• Palindromicity

We’ll use the Rockyou corpus, which is leaked password (warning, there is some bad language in the corpus)

Then, find:

• how many passwords have the word ‘pass’ in it?
• see if you’ve been owned
• count letter frequencies
• …. we’ll probably just use this
• how many palindromes are there in the corpus

Languages

• Java (if you didn’t do 1st year here)
• C
• C++
• Lua
• Go
• Bash
• Python
• Node/Javascript
• R (Not in the labs currently) (not really R’s strengths, the Dataframes are key)
• Ruby
• rust (Not in the labs currently)

Technologies

These may be programming languages to themselves, but, don’t fit the examples… they are used for other things.

Querying

• SQL (doesn’t fit well for demos - I have a bunch of sample databases to play with)
• Mongo
• Redis

TODO - explain when to use which. Why Redis (being all in-memory) is good or bad.

Could expand to discuss using AWS/cloud services to offload work?
