One pattern in the JavaScript API world that web development veterans will notice is that we’ve been creating new methods to accomplish what older, grosser APIs once achieved. XMLHttpRequest became the fetch API, some APIs like Battery became async, and there are dozens of other examples. Another API desperately in need of updating is the cookie API…and we’ve finally got…

In a recent newsletter article I complained about how researchers mislead about the applicability of their work. I gave SAT solvers as an example. People provided interesting examples in response, but what was new to me was the concept of SMT (Satisfiability Modulo Theories), an extension to SAT. SMT seems to have more practical uses than vanilla SAT (see the…

Every once in a while I get to a website that doesn’t allow me to paste into a form input. In most cases it’s something to do with login credentials (username and or password) and auth codes. So how are they preventing me from pasting information? It’s as easy as you’d think! Let’s start with the input element: The onpaste…

“To me, legacy code is simply code without tests.” — Michael Feathers If untested code is legacy code, why aren’t we testing data pipelines or ETLs (extract, transform, load)? In particular, data pipelines built in SQL are rarely tested. However, as software engineers, we know all our code should be tested. So in this post, I’ll describe how we started…

If business in 2020 has a buzzword, it’s resilience. Recent events have prompted many organisations to embark on digital-led initiatives aimed at enhancing their ability to assess and respond to the next major crisis. As more businesses make resilience a goal, it’s worth examining what that term really means, and what exactly they should be striving for.
Ever since Big Tech, fintechs and other incumbents have shifted towards a more digital and data-driven decision making approach, the payments space has emerged as one of the most competitive in the financial sector.

It’s no secret – networking and security have left the building.

Platform-first has become such a common business-tech phrase that HBR (Harvard Business Review) has coined a term for this phenomena; “‘platformania’...a land grab, where companies feel they have to be the first mover to secure a new territory, exploit network effects, and raise barriers to entry.” But, the excitement is not without reason. Seven of the world’s 10 largest global…
