I had to pick up a package keying in a 6 digit code using the below PostNL UI.
It was horrible. Don’t implement your numeric input UI like this: use a telephone keypad like or calculator numpad like keypad UI.

Gradients work best when “Inspired by Nature”, even if you live in the city.

Recommented reading and playing: [Archive.is] Practical Color Theory for People Who Code which is not just about the colour wheel, but also about:
Oh: don’t forge the “Party Mode” (:

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 bitsavers.org or scanning at archive.org as they are really hard to get.
A few search queries I used:
The PDFs I think are most interesting:

Below is how tables should look like.
Thanks Thomas Mueller (dummzeuch) for pointing me to André Vatter – Google+ – Wie Tabellen eigentlich aussehen sollten: .

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 formula 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:
http://www.mathjax.org/Here’s the post where I talk about it and how I tweak the expressions:
http://blog.boyet.com/blog/blog/tightening-the-feedback-loop-when-writing-latex-expressions-for-mathjax/If you want to experiment writing such expressions, I have the page I’m describing in the above post online:
http://blog.boyet.com/blog/files/uploads/MathJaxFeedback.html
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.

Now for some lighter Delphi XE3 related stuff:
These icons seem to go very well with the Metropolis UI Applications that you can create (and convert from VCL!) with Delphi XE3 (see the XE3 video at 0:30).

It seems quite a few “web 2.0” apps too have the same glitch: they throw away user input when the first page finishes loading.
This is especially noticeable on slow connections (UMTS, DSL that is a long distance from the phone company, EDGE, GPRS, etc): the connection speeds that a lot of developers don’t seem to test on.
So, the sequence of events goes like this:
Or more general:
when you start typing in a Web 2.0 app which is still loading, almost all the times you loose your input.
And since there is usually no visual clue when the Web 2.0 app has finished loading, you have to wait until you feel comfortable not loosing your input.
Bad!
Examples that get this wrong:
Please add your own in the comments…
