Crossrulz,
Thanks for taking the time to reply.
This year we are trying something new at the US CLA Summit. There is a third day devoted for us to have work sessions. For the most part the topics of the work sessions will be determined based on what we learn on the first two days. However, I would like for there to have some options before the CLA Summit, so people are encouraged to stay for that third day.
One idea I had was to have one of that work session be about OpenG. Crossrulz, would you be interested in such a session?
I hope you do get to go, it is a great time for us LabVIEW fans

I am excited -- it's a cautious excitement as this takes me well outside my comfort zone, but excitement nonetheless.
I read recently that "life starts where your comfort zone ends". I wish you the best and that you enjoy this new role as much or even more than your current one. You have always been an inspiration and we have all learned from you, partly because you love what you do, you are good at it and you enjoy it.

Since I know some of you might be loosing sleep over this issue
here is the latest response from an AE in the forum post:
"
Hey Fab,
I have been able to replicate what you are seeing using your code. I was originally testing on LabVIEW 8.6 and I think what you have found may be a bug in the 2011 version of the C Code Generator. I am going to continue to work on it here and will post back with a solution or work around when I get it.
"
So, it might be that nobody at NI ever ran this example in LabVIEW 2011 until now...
anyway, I will keep you posted, so you can be able to sleep again

Have you tried a screen recording app like FRAPS? That might let you catch what's going on in the window. I can see your target is Linux, have you tried compiling for win32 and checking the results?
I tried with jing when I did the video for the post, but I couldn't see anything, even when I went frame by frame. Compiling for win32 was going to be my next attempt.
I also tried "./GCD.exe" instead of run GCD.exe. That let me see the result, but the result is wrong. I get 1629764006 as a result, which is not the greatest common divisor between 12 and 15
And I get that long number as a reply no matter what arguments I give it. So there might be something else wrong here. If I make it work, I will let you know.Thanks,
Fab

Did any of you ended up trying the LabVIEW C Generator? Did you try NI's example? I have been trying to make the shipping example work following their instructions and I can not get it to work.
Here is my cross-post including video and snapshots of my steps to follow the instructions in the "Getting Started with the NI LabVIEW C Generator":
I am sure I am missing some little obvious step, I just have been away from text based programming for a very long time (thankfully )
Thanks,
Fab

Do we have the latest TLB version with REx?
-
Thanks for bringing it up to our attention, I know I would use this! Just voted for it
-
thank you all! I knew I could count on you
I already submitted feedback for the knowledge base entry asking them to update it and point to the link Jeffrey posted.
Thanks again,

Hi,
Next week I am teaching a LVOOP course and my students use TestStand a lot and I expect to get questions regarding the use of LVOOP and TestStand. The things I have heard are:
- TestStand does not recognize LVOOP Objects, so the developper has to flatten the Object Reference to string and then pass the string to TestStand, and viceversa, if they get the flattened Object they need to unflatten to string in LabVIEW: http://digital.ni.co...62573A9004C5A07
- Dynamic dispatch is lost
Are there any other tips/tricks/myths I should be aware of?
Thanks,
Fab

Dear CLAs,
The call for submissions had been posted at the CLA Community:
https://decibel.ni.com/content/docs/DOC-19083
Please check it out and start thinking what you are going to present at the summit.
Thanks,
Fab

The voting for CLA Summit 2012 topic will close on Saturday, October 15. If you are a CLA, please vote if you haven't done so here!
Thanks,

I use the benchmarking code provided in the Trim Whitespace thread. So I found that the fastest times for String Subset are roughly 3x (2.6 once I made both subroutine priority) faster than the fastest Byte Array times.
Thanks for the tip, I like that and I will use it in the future for any benchmarking.
That's true, that it's implied by virtue of it being in the string palette, but it's name is not scoped to "OpenG String.lvlib" so there's the possibility of a name collision with some other OpenG VI. Also, if someone is using QuickDrop (Darren Rocks!!!) then they won't know that "to Character Array" takes a String as an input.
I agree that adding the String to the name will provide clarity and I do use Quick Drop and like it when the vi names are more descriptive.
-
I have also been told that fools seldom differ.
hey, like my mom says: (translated from Spanish) "I raised you like a palm tree and you threw me like a coconut"
seriously, how did you benchmark your code to determine it was 3x times faster?

I find the VI useful and I think it should be part of OpenG.
I made the following modifications for speed:
But when I benchmark it some times it is faster, but some times it is not. It seems that the original version is more consistent:
Original code:
Modified code:
I am attaching the Benchmark VIs I used:
TEST - To Character Array-modified.vi
BenchMark-To Character Array-modified.vi
BenchMark-To Character Array.vi

I guess I need to learn to post a lot faster !!! But hey, great minds think a like

If you are a CLA, we want your feedback, the call for topic ideas for CLA Summit 2012 is here:
https://decibel.ni.c...nt/thread/10492
CLA Summit 2012 will be March 5 - 7
Thanks,

If you know any UTS alumni that might be a good candidate for the International Alumni Award, then I'm sure they're apprecaite you nominating them here... Maybe someone you know who, oh, I don't know, graduated their physics degree in 1995? Someone who is one of the administrators of the largest independant LabVIEW community in the world? Know anyone like that?
they ask for your phone number and e-mail, if you want, send me those via private message.

The food service at the party vividly demonstrated the inherent limitation of a single-threaded apartment model...
Agreed, I hope a NI engineer didn't design that line Plus the vegetarians in the crowd did not feel the love between the horrible lunch and the dinner served

Yer, that sounds like a great idea. It's just a long way coming from Australia.
But so worth it and you could accumulate more frequent flyer miles

Je ne suis pas sûr que c'est vrai - la plupart de mes française vient de Google Translate
I knew it!

Unfortunately not this year
But definitely next!!
Maybe you could come every year: one year for the CLA Summit and one year for NI Week. It would be better than every other year
-
Thanks guys!
Are you going to come to NI Week this year? so we can congratulate you there in person
-
Another fantastic door prize:
Jeffrey Travis gave me a signed copy of LabVIEW for Everyone. I asked Jim Kring and Lisa Wells and they both will sign it.
See you next week!,
Fab

Thank you for your answer.
J'espère que nous aurons l'occasion d'échanger quelques mots lors du BBQ
A bientôt
Olivier
Bien sûr. Je parle mieux Français que je l'écris
Puis-je avoir un pain au chocolat s'il vous plaît?
pas de pain au chocolat por vous!

Congratulations !!!
CLA Summit - who is going?

I will be at both CLA Summits.
However the work sessions will only take place at the US CLA Summit.
Neil, I can let you know what we discussed at the US Summit when we meet at the UK one
John and Crossrulz,
Thanks, I will keep you posted of what we would do on the third day for OpenG.
Thanks,
Fab
