UI-Design: View 2-D, Navigate 3-D?

Over-and-over again 3-D User Interface design was heralded "dead".

The flat 2-D screen is a natural fit for orthographic projection of flat imagery like 2-D spread sheets, tables, lists and linear text.

On the other hand, much of what is shown on a (2-D) screen is projected 3-D content, be it from computer games or from movies.

Most human beings navigate and move in the physical world, and the brain makes sense of this world by encoding it as a 3-D space, the brain is hardwired to process, remember filter and associate information in context of a 3-D world.

That's why I think that UX/UI design will benefit from using 2-D for data representation and form input, and closed-space 3-D for navigation through the application.

Learning Haskell, functional music

As you might have realized, I started to learn Haskell. One of the most fun things to do in any programming language is creating some kind of audible side effects with a program. Already back in the days when I started programming, I always played around with audio when toying around with a new language. I have found a wonderful set of lecture slides about haskell and multimedia programming, called school of expression. Inspired by the slides about functional music I implemented a little song. Ahh ... and yes it is intended to sound slightly strange . I used the synthesis toolkit to transform the music to real noise, simply by piping skini message to std-out. I used this command line to achieve the results audible in the table: sven@hhi1214a:~/Mukke$ ghc -o test1 test1.hs && ./test1 | stk-demo Plucked -n 16 -or -ip Sound samples: Plucked play Clarinet play Whistle(attention very crazy!) play As always the source... stueck = anfang :+: mitte :+: ende anfang = groovy :+: (Trans ...

The purpose of the MOCK

In response to a much nicer blog entry, that can be found here . There are actually several distinct "tests" that make up usual unit tests, among them two that really do stand out: one kind of testing to test method flows, one to test some sort of computation. Mock objects are for the purpose of testing method flows. A method flow is a series of message transmissions to dependent objects. The control flow logic inside the method(the ifs and whiles) will alter the flow in repsonse to the parameters of the method call parameters passed by calling the method under test, depending on the state of the object that contains the method under test and the return values of the external method calls(aka responses to the messages sent). There should be one test method for every branch of an if statement, and usuale some sort of mock control objects in the mock framework will handle loop checking. BTW: I partly use message transmission instead of method invocation to include other kind...

Keys, Values and Rules: Three Important Shake Concepts

The title was a click-bait! This article will actually try to explain five instead of three important notions in Shake. These are: Rules Keys Values The Build Database Actions This short blog post was inspired by the hurdles with my Shake based build, after the new Shake version was released, which had breaking API changes. Jump to the next section if you are not interested in the why and how of this blog post. Shake is rule based build system much like GNU make. Like make it is robust, unlike make, it is pretty fast and supports dynamic build dependencies. But you knew all that already, if you are the target audience of this post, since this post is about me explaining to myself by explaining to you, how that build tool, I used for years, actually works. Although I used it for years, I never read the paper or wrapped my head around it more than absolutely necessary to get the job done. When Shake was updated to version 0.16.x, the internal API for custom rules w...
