PHP 5.7 now nearly twice as fast as PHP 5.6

Interactive Programming in C
I’m a huge fan of interactive programming (see: JavaScript , Java , Lisp , Clojure ). That is, modifying and extending a program while it’s running.

Programming without objects
Recently I gave an itemis internal talk about basic functional programming (FP) concepts. Towards the end I made a claim that objects and their blueprints (a.k.a. classes) have severe downsides and that it is much better to "leave data alone", which is exactly how Clojure and Haskell treat this subject.

The Dentist Office Software Story
I’ve been telling this fictional story about Dentist Office Software for years to describe why we are so focused on our “networks” investment strategy. Yesterday I told it at a HackNY event we did at the USV office and my partner Albert provided a finishing touch that really drives it home. Since I’ve never told […]

When they start using Docker, people often ask: “How do I get inside my containers?” and other people will tell them “Run an SSH server in your containers!” but that’s a very bad practice. We will see why it’s wrong, and what you should do instead.
