Easter eggs on

Easter is long gone, but that doesn’t mean everyone has found all the easter eggs on this website. Here’s a cheat sheet!

I often try to put easter eggs in things that I build, and this website is no exception. This page lists all the easter eggs that have been around for a year or longer. Can you find them all?



The Konami code is a cheat code that can be found in many of Konami’s video games. It’s been around in one form or another since 1986. Entering the sequence  ↑   ↑   ↓   ↓   ←   →   ←   →   B   A  would typically grant the player more lives or power-ups.

Later on, games from other publishers also started including the cheat code. In many games the code could be used to make the player’s life a bit easier, but in others inputting the code would merely reveal a “useless” easter egg. The Konami code even works on some websites – mine is one of them.

When in Rome…


Most of the articles on this website are about things that are new and shiny, like software engineering, technology, and science. A few are about classical antiquity or have a header image that includes elements from the classical era.

You’ll find that the website footer for these “classically themed” articles looks slightly different, as does the list of suggested content directly below those articles.

In the Chungle


For some weird reason people keep misspelling my name as “Chung” all the time. I’ve seen “Chungs” in a countless number of business emails, on shipping labels, in my employment contracts, and even on my bachelor’s diploma. It’s also not uncommon for people to confuse me with other Asians whose name happens to start with a “C”. I have a special page (in Dutch) for people like that.
