In this episode: F# 3.0 syntax; a campaign against if statements; Visual Studio 2015 update 3; laws of software craftsmanship; vulnerability on Lenovo laptops; busting a counterfeit ring; and misuse of the word ‘agile’.
Sharpen the Saw is a somewhat delayed repost of a semi-regular newsletter of information I publish for the professional development of software developers. While targeted primarily at developers working with the Microsoft technology stack, content will cover a wider range of topics.

Cheatsheet for F# 3.0 Syntax
F# is the functional language we all should be learning - not least because knowing the techniques will help you be a better developer day to day.

Newton’s 3 Laws of Software Craftsmanship
Newton’s three laws are a great approximation for the way the world works - in fact, they’re good enough that it is only when we start looking at the very small or the very fast that we need the better approximations provided by Einsteins theories.
Christian Mackeprang posts his take on three fundamental laws for software development.
- Under fixed circumstances, every solution will behave the same way unless it has been modified.
- The impact of a technical decision is directly proportional to the size of the project and to how much of it is affected.
- Every technical decision comes with an implied tradeoff.
