And… goodbye JavaScript!

When I de-bloated my piece of the web, I noted that the largest asset I was serving on my blog was a local version of jQuery – coming in at some 70+ kilobytes – that “I still need to insert into the head of my page for historical reasons: 15 years ago I in-lined lots […]

Monads for Babies

Monads for Babies is the first in a series that teaches computer science to toddlers. It’s only available in digital form at the moment (png format, embedded below), so I suggest `right-click -> print` so you can read it to the lil’ tigers at bed time: Support my Patreon if you’d like to see more.

A most useful function

Hot on the heels of my web colors rant, comes this amazing piece of Emacs Lisp I now have in my init file: (defun web-color () (interactive) (let ((cols ‘(“AliceBlue” “AntiqueWhite” “Aqua” “Aquamarine” “Azure” “Beige” “Bisque” “Black” “BlanchedAlmond” “Blue” “BlueViolet” “Brown” “BurlyWood” “CadetBlue” “Chartreuse” “Chocolate” “Coral” “CornflowerBlue” “Cornsilk” “Crimson” “Cyan” “DarkBlue” “DarkCyan” “DarkGoldenRod” “DarkGray” “DarkGreen” […]

Olive vs OliveDrab

“Name as many of the web ‘X11 color set’ named colours as you can.” should be the new fizz buzz. I think I’d do pretty good, but would always fall down on the “mediums” and “lights”. “MediumPapayaWhip? LightRosyBrown?”. If it were in an interview situation, I could talk for hours about the faded glory of […]

Graybeard

Thanks to a decreased demand in shaving recently, I discovered several grey facial hairs. It’s happening – I’m becoming a graybeard! The timing is suspicious: I start using Emacs, I turn into a graybeard. But did Emacs cause me to get grey hairs, or did the hairs coerce me into to using Emacs?

It Just Works ™

My favourite marketing phrase in all of computers is “It Just Works”. It unwittingly represents nearly all of software engineering. It just works. Only just. The absolute minimum. (Side note: my favourite marketing phrase in sports and fashion is “Just Do It”. If you have to do it, only just do it.)

JavaScript’s Numeric Separators

During a particularly-late night coding session, I accidentally discovered that JavaScript now has “numeric separators”. What started as a simple test in my browser console: `dx=100+xo`, would be drailed by a typographical error that revealed a hidden secret… `dx=100_` As I depressed the underscore-instead-of-plus key, Firefox’s auto-evaluator-thingy sprang into action and warned: “Uncaught SyntaxError: underscore […]

document.designMode?

You learn something new every day. Today I learned about insect reproductive systems, and also that document.designMode is a thing. Both seemed pretty interesting, but only the latter let’s you make any text on any web site “editable”. Open up the dev console and type document.designMode=”on”, and marvel as you can type over any text […]

Blog-o-thon ahoy!

I hereby declare my intention to spam a whole tonne of blog posts in the near future. I’ve made this declaration several times in the past – and never managed anything remotely close to “a tonne”, but this time we find a confluence of important factors – contributing to a near-perfect storm. A very-adequate storm. […]
