Practical Color Theory for People Who Code

Posted by jpluimers on 2018/06/18

Recommented reading and playing: [Archive.isPractical Color Theory for People Who Code which is not just about the colour wheel, but also about:

  • desaturation
  • mixing

Some links and references to IBM CUA: Common User Access which defines a lot of the UIs and UX we still use.

Posted by jpluimers on 2016/02/04

Back in the late 80s and early 90s of last century, engineers Richard E. Berry, Cliff J. Reeves set a standard that still influences the user interfaces and user experience of today: the IBM Common User Access.

I mentioned CUA a few times before, but since an old client of mine managed to throw away their paper originals in a “we don’t need that old stuff any more as we are now all digital” frenzy, I wanted to locate some PDFs. And I promised to write more about CUA.

If anyone has printed versions of the non-PDF documents below, please donate them to aek at or scanning at as they are really hard to get.

A few search queries I used:

The PDFs I think are most interesting:

Displaying formulas using HTML (via: More TVM–calculating the IRR : Algorithms for the masses – julian m bucknall)

Posted by jpluimers on 2012/10/04

I saw julian Bucknall post some beautiful formatted functions in a few of his Algorithms for the masses blog and wondered how he did it.

\[a = P . r^N . \frac { (1 – r) } { (1 – r^N) }\]

Why is his forumla code looking so simple, and why doesn’t it display on my blog?

So I asked him (:

Hi response was “use MathJax“:

I’m loading the MathJax JavaScript library in my pages:

Here’s the post where I talk about it and how I tweak the expressions:

There are various ways to include the MathJax JavaScript, and if you do, you can use both LaTeX and MathML style formulas. Read all about it on the MathJax Getting Started page.
