This is an open letter to Mark Rendle, the presenter in this talk:
https://skillsmatter.com/skillscasts/6088-the-worst-programming-language-ever
Mark,
I really enjoyed your presentation on the Worst Language Ever. I have a couple of suggestins for improvement.
I think Pascal's assignment and comparison operators should be adopted here. That is, you should do assignments as in:
| These are three exercises that deal with the thought process of converting data from one format to another, | |
| a problem we enounter often in software development. The last problem is about publishing this data, both | |
| as a website and as a webservice that publishes json. Tackling that problem will make you think about | |
| various things like "how do we get the data off of the websites we're referencing?" and "when do we update | |
| that data?" that can lead to great architectural and structural conversations. | |
| Exercise #1: |
| The KnockKnockinator | |
| We're going to write a class that listens to and responds to knock knock jokes. | |
| An interaction with this class should look like this: | |
| > inator = KnockKnockInator.new | |
| > response = inator.hears("Knock Knock") |
| # once upon a time these rake tasks were in use in my house. I had a program that would scrape my kids | |
| # TV shows off of my tivo as they were recorded and dump them in a directory. Of course, they had tivo's | |
| # encryption on them. the 'decode' task transcoded them to mp4 and moved them to a different directory, | |
| # and the 'publish' task would copy them to a generation one Apple TV (the one with the 40 gig hard drive). | |
| # My kids then had a never-ending source of Dora and Dinosaur Train, and I had vital space on my Tivo for | |
| # things like "The Walking Dead". With a parental code in my Tivo, my kids' shows were sandboxed in a | |
| # safe place. | |
| # | |
| # I presented this code as an example of automation in a conference talk done several times, and this code | |
| # was actually taken off of a slide used for that talk. As such, the original code was a little longer |
