Biggest image in the smallest space
What’s the biggest pixel size of a PNG image in the smallest number of bytes? I wanted to try to create an image that could be downloaded but whose pixel buffer would be too big to store in the RAM of a PC. Here is a PNG image of 6,132,534 bytes (5.8 MB) and 225,000 × 225,000 pixels (50.625 gigapixels), which, if…

CoffeeScript: less typing, bad readability
I’ve used CoffeeScript for a few months now. Coming from Python, I felt that CoffeeScript was more concise than Javascript, so I decided to use it for a few small projects. Initially, it was a nice experience, but then I gradually realized that, while writing CoffeeScript code was very pleasant, reading it wasn’t so…

Golden Rules of Interface Design (2013)
I have often been asked to distill the vast corpus of user interface design into a few key principles. While I was reluctant to do this, it turned out to be a good exercise to write “Golden Rules,” that are applicable in most interactive systems. These principles, derived from experience and refined over three…

Go += Package Versioning
More precisely, we need to add the concept of package versions to the working vocabulary of both Go developers and our tools, so that they can all be precise when talking to each other about exactly which program should be built, run, or analyzed.
