TypeScript and Substitutability

When starting with TypeScript it took not much time to stumble upon some of the type system’s odds. Odds that make a lot of sense if you take a closer look. In this article I want to show you why and how in some cases, TypeScript allows non-matching method signatures.

Saving and scraping a website with Puppeteer

For some of my performance audits I need an exact copy of the webpage as it is served by my clients infrastructure. In some cases, it can be hard to get to the actual artefact. So it’s easier to fetch it from the web.

Cutting the mustard - 2018 edition

The other day I was holding a workshop on performance optimisation for single page applications. For this workshop I needed an example that I could optimise step by step. I decided not to use a framework, as I didn’t know the experiences and background of my attendees. Also, I didn’t want to draw attention to framework details, rather focus on concepts that build on the platform and that are universally applicable to SPAs.

However, every once in a while you will find yourself in front of a Wordpress blog that has way too many articles (and way too many authors that fear change!) to be reasonably transferred.

My most favourite podcast episodes in 2017

My most favourite books in 2017

I started taking reading seriously again in 2017. I had highs where I read about 10 books a month (phew), and also lows where I haven’t touched a page for a couple of months. Now with having both a toddler and a Kindle*, I gladly spend night again guarding the crib while reading both fiction and non-fiction. And oh, did I read a lot of non-fiction this year. There were some amazing books, and I want to share with you the ones that I found the most compelling.
