Rube Goldberg Code

[altenbach]

... the code would probably look like that (only a small section is shown):

Gotta love those icons of the prisoner behind bars in a cell, he's not a happy camper! Hope it's not controlling a high security prison.

Oh yes, I just love these (semi)-literal icons. After all, he's in a cell. 🙂

Long ago, I made an icon for the vampire challenge containing a bat flying at night, with the moon in the background. (http://zone.ni.com/devzone/cda/tut/p/id/5303) .

Even longer ago, in the LabVIEW stone ages where support for conversion between big- and little-endian was not natively available, I had a subVI that did it. Most appropriately, the icon showed an American Indian, with a nicely colored feathered head dress. In these times of political correctness, this may no longer be doable. :o.

Nah, looks like his indexing started at 1, a for loop never would have worked.  😉

Oops!

I just Rube Goldberged.

After developing an example that reads various clusters from fixed length record files I noticed it was a convoluted way of copying control values to indicators.

Let's see, in order to logically merge two simple boolean conditions, we need to convert one to a DBL using a formula node, another to a I32 with a case structure, do a coerced bitwise comparison (that can end really bad unless we are only dealing with 0 and 1), convert the result to a SGL (???) and see if the result is not equal to zero. 😮 Whew!!!

(silghly adapted from http://forums.ni.com/ni/board/message?board.id=170&message.id=238065#M238065, the original code had a few more wire bends and covered more area).

Okay, the classic "is true = true?" it must be true.  Let's make an extra branch of that and pass that also into the true case that does nothing.

I wonder what the false case is supposed to do?

TiTou RE:


That is not fair TiTou. You forgot to tell that this VI is part of a polymophic VI that adapts to array inputs of base path and relative path.

[altenbach]

One way to invert a boolean would be to (1) convert it to 0/1, (2) see if the result is zero.

Of course we could just wire the boolean directly to the case structure and swap the two cases, but... 🙂
