Rubber Duck Debugging

27 Feb 2019

Talk to the Duck

When confronted with a problem, don’t ask the person next to you for help right away, he’s probably doing something important as well!

Instead, first tell the duck about it - out loud. If you don’t get to a solution, start explaining your problem in more and more detail until it hits you. If the mere explanation led to a solution, you avoid unwillingly turning your colleague into a CardboardProgrammer.

Array.prototype for .NET developers

24 Feb 2019

The Array.prototype functions have been available for a long time but it’s since Arrow functions that “Linq lambda syntax”-like functionality is available in JavaScript.

This blog post explains the most common functions by comparing them to their C# equivalents.

A basic example:

// JavaScript
const result = [0, 1, 2, 3, null]
    .filter(x => x !== null)
    .map(x => x * 10)
    .sort((a, b) => b - a);

expect(result).toEqual([30, 20, 10, 0]);

// C#
var result = new int?[] {0, 1, 2, 3, null}
    .Where(x => x != null)
    .Select(x => x * 10)
    .OrderByDescending(x => x)
    .ToArray();

Git Assume Unchanged

18 Feb 2019

Ideally one would create a new gitignored file to configure an application to fit his local development environment but when you do have to revert to modifying a committed configuration file, at least there is “git assume unchanged” to avoid committing your changes in these files accidentally.

Assume Unchanged

# Git assume a file
git update-index --assume-unchanged fileName

# And unassume with
git update-index --no-assume-unchanged fileName
