Brent has some thoughts on strong and weakly typed programming languages. Starting point: a simple function that needs testing: rgbToHex(red, green, blue) { // … } Testing the result the function should return is easy. But what about edge cases? What happens though if we pass doubles instead of integers? Or numbers outside of the […]

Layers of Technical Debt and Complexity
On July 8, 2015 the New York Stock Exchange went down due to a software glitch. Over at Medium, Zeynep Tufekci went into detail on how it comes that software sucks. Software sucks for many reasons, all of which go deep, are entangled, and expensive to fix. […] LAYERS AND LEGACIES: A lot of software […]
Falsehoods programmers believe about time and time zones
Every day has 24 hours Every day without DST changes is 86400 (60 * 60 * 24) seconds long Every day in UTC is 86400 (60 * 60 * 24) seconds long Week one of a year starts in January every year If I know what time zone someone is in and they just tell […]
Swift Cheat Sheet and Quick Reference
Swift Cheat Sheet and Quick Reference → Sidenote: I cannot stop laughing at this sentence that made it onto the Apple site introducing Swift. Swift is the result of the latest research on programming languages. Namespaces and closures; ORLY?
Typing.io — Typing Practice for Programmers
Practice typing the awkward characters in code. No drills — type through open source code in JavaScript, Ruby, C, C++, Java, PHP, Perl, Haskell, Scala, and more. Fun to see how much I actually mistype whilst trying to be fast, and how my IDE autocorrects for me 🙂 Typing.io →
Head code is all gone!
How familiar 🙂
Coding-Style Conventions
Analyze Github commits to know which convention is popular. Instead of arguing where to place spaces and where not, just check GitHub to get to know the popular convention. Don’t agree on tabs vs. spaces though. Go #teamtabs! Popular Coding Convention on Github →
CHOC — Traceable Programming
Choc is a tool for thinking powerful thoughts by stepping through code. It is an implementation of several ideas found in Bret Victor’s Learnable Programming. Bret Victor’s Learnable Programming was an eye-opener. This tool is the JavaScript execution of that eye-opener Choc →
Declarative Programming
Declarative programming specifies what the computer should do, not (as we saw with imperative programming) how it should be done. In CSS for example: turn all paragraphs red; I really don’t care how it happens, just make it so. — John Allsop, Not Real Programming
