LabVIEW proverbs!

altenbach — Sat, 29 Jan 2005 20:00:47 GMT

Since we don't have a social forum for the less scientific aspects of our beloved software, lets try to collect LabVIEW related proverbs here. They can be profound or silly, serious or funny. Anything goes!

Let me start: 🙂

=============================================
A diagram is worth a thousand lines of code!
=============================================

=============================================
Just go with the (data) flow!
=============================================

Nice Idea. I just hope people won't put in stuff like "Each thousand VIs project begins with one control".
Don't you think this should be moved to the special interest board? Also, I think some quotes would be nice.

If at first you don't succeed, go ask Greg.

Rule of acquisition #3: "Never spend more for a (data?) acquisition than you have to".

"We've forwarded it to the R&D team and it will be fixed in the next version...". Just kidding...

And finally:

Nothing is impossible, as long as you have a DLL.

(So far, there is only one "special interest board", and it's for feedback on the forum. I actually composed this thread there, but in the last minute decided to post it to the LabVIEW area. I don't mind if the moderators decide to move it to a better place. 🙂 I suggest creation of a social/recreational board for this purpose).

=============================================================
A local variable is like Duct Tape.
=============================================================
(Typically used for everything (except ducts!) as a quick but ugly temporary fix that later tends to gum up things).

Excellent thread and post!

I have to confess my pleasure with many of Rolf Kalbermatter's writings. I find his comments both humorous and well put.

His reply from this thread

http://forums.ni.com/ni/board/message?board.id=170&message.id=101699#M101699

I reporduce here

"...control uses internally an int16 for the
TopRow value, eventhough the according property node uses an int32. Bad,
bad, bad!!!"

If I find the original I will re-post, but my favorite was from Rolf Kalbermatter on Info-labVIEW.

There was a discusion there of the use of "super-cluster"s (i.e rediculously larage data structures) and arrays in shift registers and effective methods of managing same.

From memory the quote was;

========================================================================
"Once you all of your physical memory is used up by a single shift register,
========================================================================
your application is probably going to s#%@ !"

You may be suprised how many times I have quoted that phrase to my coustomers.

Ben

That's a good one altenbach!

I agree, we need a social club type of area. A place to meet. It would be good to get to know other enthusiats' other than competing for the answers. Maybe discover that Dennis has a life other than LV 😉

I worked with a guy who loved to put clusters into shift registers..

"it looks better".. he used to say.

He left the company..

Guess who had to clean the code.... 😠

(did I mention that he left BEFORE completing his code???)

I should put this into the "forum wish list"...

I forgot to quote Ben in my last one.. I'm sure you guys figured it out..

Great Thread!
I've also got a good one:
Time ago I had to modify a large LV application made by an engineer who condidered himself a LV 'guru'. Before showing me the code he said:
< For this application I used the stratified programming. It makes the diagram much easier to read! Ever heard about that?>
I was wordless, my answer was < I admit my ignorance, I didn't have the chance...>
Well, the diagram was a huge sequence structure, 86 frames, with others 24 nested sequence structs. The concept of sub-vi was totally absent from that guru's head!!!
Since the day I got the job done, I get an allergic attack whenever I see a sequence with more than 2 frames!

Christian, I can't resist to put a famous quote of yours in this thread:
==============================================================
"1" cannot be represented exactly in binary...

To be fair see the full context here.

Here is another classic understatement;

In this thread

http://forums.ni.com/ni/board/message?board.id=170&message.id=45982&query.id=0#M45982

we were congratulating Dennis for passing the 1000 answer mark (Note: answers not postings!)

Part of his reply was

"I had no idea I've been so chatty here."

One sticky point is trying to assign authorship to things like that, that's why I left out any sources. The first occurence of this proverb (that I am aware of) is one of my info-labview or usenet posts from way back in the last century. I actually got a private e-mail after my post asking permission to quote it in a presentation. I cannot say if it hasn't been used even before that, it seems so simple. 🙂

Ben, you should have the honnor of starting the thread when he reaches the 4000 mark.

You should quote what he said at the 1000 mark..

My ten commandments:

1. Thou shalt not have any text languages before me.
2. Thou shalt not make two different event structures.
3. Thou shalt not take the name of Jeff Kodosky the creator in vain.
4. Remember the type def, to keep it strict.
5. Honor the wire and the shift register.
6. Thou shalt not skip reading the manual.
7. Thou shalt not commit a sequence structure.
8. Thou shalt not wire underneath objects.
9. Thou shalt not bear false witness against LabVIEW for memory leaks.
10. Thou shalt not covet the loacal variable.

I like the commandments, but I have to confess my ignorance.

"4. Remember the type def, to keep it strict"

Could anyone help me understand why "to keep it strict"?

Good morning Ben,

I'm in the same boat as you. It's the only one that I didn't get.
It must be "thee" one that separateth thee boyz from thee men (or Dennis).

Dennis_Knutson — Tue, 01 Feb 2005 14:16:20 GMT

Joe and Ben,

Please take the "commandments" with a big grain of salt;). I refer to a strict type def and the rhythm of the sentence appealed to me more than anything else.
