This article gives a practical introduction to WebAssembly.### GotalkGotalk exists to make it easy for programs to talk with one another over the internet, like a web app coordinating with a web server, or a bunch of programs dividing work amongst eachother.### The 1950s called and wanted their toolbox backYour favourite fancy-pants modern programming language is from the 1950s. Pretty much any programming language used today is a derivative of Fortran or Lisp, both born in the 1950s. Okay, reality check: It’s 2013—yes, 60 years later—and we have cars that drive themselves on the street, robots roaming the surface of alien planets and tiny networked devices with interactive surfaces that we keep in our pockets, which are orders of magnitude more powerful than the computers of the 1950s.### The Definition of Design### Sol — a sunny little virtual machineDuring this weekend, together with a few evenings earlier this week, I created a rather simple virtual machine dubbed Sol, after the Swedish word for sun. It’s register based with multitasking and timers.### Browse all 512 articles →I’m a Swedish he/him living in SanFrancisco, California.Software is the medium through which I express myself.The same call, in code.
