According to a W3Techs survey, the images on 74 percent of websites worldwide are in JPEG or PNG format and for good reason: those images display well on all browsers. However, several newer image formats are well worth consideration, a leading example being WebP. This post describes how to adopt WebP as your image format and, accordingly, lower your image weight by approximately 30 percent and reduce the load time of your websites or native apps.
Cellular Automata are pretty cool things to play with. There are many, many variants, like Conway’s Game of Life, Abelian Sandpiles, Langton’s Loops and Brian’s Brain, but in this blogpost, I’ll just talk about the simplest kinds of cellular automata: one-dimensional cellular automata.
JPEGs, PNGs, and GIFs — oh my! Most web developers only learn which format to use through trial, error, and long experience, and not necessarily by fully understanding how these formats actually work.
In part one (One pixel is worth three thousand words) of this turned-to-be-two-part blog post, I discussed one-pixel images and how well different image formats “compress” these images. I was surprised how much there is to be said about the matter. This was supposed to be a short blog post, describing one-pixel images and how they compress, and instead it became a glorious monster (and also a two part blog post…).
A couple of months ago while taking a break from implementing cool new features like q_auto and g_auto, I was joking in our team chat about how well various image formats “compress” one-pixel images. In response, Orly — who runs the blog — asked me if I’d write a post about single-pixel images. I said: "Sure, why not. But it will be a very short blog post. After all, there’s not much you can say about a single pixel."
