Searching the Creative Internet
I had of late been lamenting the loss of the internet of the 1990s. A place where everything was obscure or new. If you saw something mainstream like a Disney princess, it was because someone had taken the time to handcraft an ASCII art portrait. Today if you type [disney] into the ubiquitous search engine , every…

Major sites running unauthenticated JavaScript on their payment pages
A few months ago, British Airways' customers had their credit card details stolen. How was this possible? The best guess goes something like this: BA had 3rd party JS on its payment page <script src="https://example.com/whatever.js"></script> The 3rd party's site was hacked, and the JS was changed. BA's customers ran…

“Stylish” is back, and you still shouldn't use it

One of the world’s most visited websites that nobody is aware of (2017)
The editorial department of well-known Dutch broadcaster RTL News recently asked for my assistance. Multiple tax files of Dutch citizens had been published via www.docplayer.nl and no one could explain – where did these files come from? Who would have thought that my research would lead to the discovery of one of the…

Post-REST
More or less all the big APIs are RESTful these days. Yeah, you can quibble about what “REST” means (and I will, a bit) but the assertion is broadly true. Is it going to stay that way forever? Seems unlikely. So, what’s next?

ReasonML: Strict, powerful and forgiving
I gave this talk at JSFoo, Bengaluru, in October 2018. It describes my experience in switching to ReasonML on the Turaku project and how learning to use a statically-typed functional programming language involves much more than learning the language's syntax or features.
