Update - Feb 2020 These instructions are no longer required for macOS Mojave 10.14 or later. Updating to the latest macOS version should be enough to make Nanos based on CH340G chipset work. In fact, installing these drivers on macOS Mojave 10.14 or later could cause OS issues! Original Post I recently bought some really cheap Arduino Nanos. These were based on the CH340G chipset. Unfortunately, when I loaded the Arduino editor and tried to push code onto one of them, I discovered that there was no USB serial driver available to select.

These are a bunch of docker commands that I find useful for keeping things tidy. Remove all orphaned images. These are the images tagged as <none>. docker images -q --filter "dangling=true" | xargs docker rmi Delete/remove all stopped containers. Note that -v option; it will also delete any persistent volumes that belong to the stopped containers. docker ps -aq --filter "status=exited" | xargs docker rm -v && docker ps -aq --filter "status=created"

I have recently switched to a MacBook Pro as my daily driver. One of the first things I noticed was that there was no maximise button on application windows, only a fullscreen option that hides the top status-bar. A quick google search told me that double clicking the title-bar or holing down ALT while clicking in the Green Icon would maximise the window instead of making it go fullscreen. Which is great!

For my latest javascript/threejs experiment I created a retro 1980’s inspired demo, which renders hundreds of sprites in a pseudo 3D style that was common in the Atari ST and Amiga demos of the late 80’s. Of course, no retro demo would be complete without a retro soundtrack. For my Retro Particle Demo this would be a short track that loops continuously. My initial attempt used the html5 audio tag: <audio id="demomusic" src="audio/music.

A list of machine emulators completely written in JavaScript that I find to be both impressive and interesting. Writing an emulator in any language is difficult and requires some serious programming chops. But to do it in JavaScript must surely require a level of programming genius (or maybe madness - I hear it’s a fine line!) that us mere mortals can only dream of aspiring to. These are my favourites that I’ve stumbled across, catalogued here so I can easily find them again whenever I feel the need for a retro computing fix…
