Applied Functional Programming with Scala - Notes

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

Notes from Coed:Ethics conference, London, 13 July 2018

Cori Crider - "When data kills" / Weaponised AI

• Imam Salem bin Ali Jaber preached in Yemen against Islamic extremism; guest at a wedding of relative; hit by a US Hellfire missile fired from a drone. Relative Faisal made contact with Cori, went to Washington DC. No explanation ever made by government (although compensation was paid).
• Decision-making process behind the attack not known exactly. But there is significant evidence that such attacks serve to further radicalise people; attack results in ~3x more new recruits than extremists killed by attack.
• Most drone attacks are not on named individuals, but rather "signature strikes" — a euphemism for killing people the military doesn't even know, but who match a certain behavioural pattern (perhaps based on metadata — Hayden: "we kill people based on metadata"
• Skynet (known through Snowden relevations): use machine learning to try to find courier

CoEd:Ethics

Introduction by Anne Currie (@anne_e_currie)

• Why are we here?
  • Is there a problem with ethics in and around technology use at the moment?
  • If there is an issue, what can we as engineers do about it?
    • What might stop me?
    • How can I get around that?
• There is a workbook for the conference
  • It looks a bit like the ones DareConf used to do

               if (values[i-1].stack) {
                  str += values[i-1].stack;
