Legacy Code Rocks Menders love fixing bugs, refactoring, and testing to make software applications more stable, scalable and secure.
This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.
Agree? Disagree? Feel free to let me know at @JanStette. See also my blog at www.janvsmachine.net.
Keep it simple, stupid. You ain't gonna need it.

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !
myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

In Elm, signals always have a data source associated with them. Window.dimensions is exactly what you think it is, and you can't send your own events on it. You can derive your own signals from these primitives using map, filter, and merge, but the timing of events is beyond your control.
This becomes a problem when you try to add UI elements. We want to be able to add checkboxes and dropdown menus, and to receive the current state of these elements as a signal. So how do we do that?
| -module(dojo4). | |
| -import(lists,[nth/2]). | |

| -compile(export_all). | |
| rand_list(Size) -> | |
| lists:map(fun(X)-> random:uniform(100) end, lists:seq(1,Size)). | |
| grid(Size) -> | |
| lists:map(fun(X)-> rand_list(Size) end, lists:seq(1,Size)). |
