Ok, I got back from an eye exam.  Strangely my vision changed.


It had been stable for so many years I had stopped bothering to go.   


No diabetic problems but my thyroid replacement has been retreated a few times.


What can cause a large shift toward the good?  I could Google it but, then I actually know a research opthamologist so,  O.S. moved from -1.75 to -0.75 with no astigmatism change and O.D. -1.0 to -0.5.


Is it a benefit for knights?

Users in Iran cannot post on forums?

Sun, 28 Jan 2018 17:33:40 GMT2018-01-28T17:33:40Z

I just saw on LinkedIn that someone in Iran received an email from NI that the forums would be "read-only" for them from now on due to export controls and not wanting to encourage the purchase of NI products in Iran. Has anyone else heard similar things or can verify whether this is true or not?

Tue, 23 Jan 2018 18:28:59 GMT2018-01-23T18:28:59Z

So I registered for a NI Web Event and don't have the link to it and I can't seem to find a record of this registration anywhere I know there is a link to this event in my e-mail, but I don't have access to my email at this time.

The event is First Look: The Newest Version of LabVIEW NXG and it is today. I found on out in February.

Anyone know how to find (or have) the link to this event?

Many thanks,

I would love working on all the different technologies, but let's get real about the pay.



LabVIEW Full Stack Developers/Engineers

Thu, 11 Jan 2018 09:02:45 GMT2018-01-11T09:02:45Z

Hi All,


Can we call ourselves (us, LabVIEW Application Developers/Engineers) proudly as "Full Stack Developers" (in the Agile world terminology), since most of the times, we develop & integrate an entire application from scratch, with a fairly wide functional knowledge of most of the (if not all) modules/subsystems of the application?!


I expect all your views & opinions, and more light on the topic!

Intel CPUs exploit

Have you guys seen this recently?

And Intel side:


I am not really expert in computer security, is this really bad? Besides, they say the patch (if your mobo manufacturer makes any) might cause a 30% performance hit on your system...

Happy New Year everybody!

Check your community docs people, some unproper work is going on from NI side!

Fri, 15 Dec 2017 07:29:54 GMT2017-12-15T07:29:54Z


I just had to realize that one of my community doc page got changed in this year August: " **This document has been updated to meet the current required format for the NI Code Exchange.** "

This doc (see the document history for the changes):

A community folk added some alien info into my document, and updated some other parts too: (i guess he was working on several docs at the same time, and copy/paste went haywire?? (image) )


Steps to Implement or Execute Code

  1. Download the .zip file
  2. Set your desired configuration (a, x1, x2, degrees, etc)
  3. Run the VI

After using this false info in this document section, he put the original list of steps into an updated snippet (you can see also Asian character at the Case structure) this is the "current required format for the NI Code Exchange"?? (image)



Anyway, I fixed the section "Steps to Implement or Execute Code", but I will also check other docs for such mistakes. So I really encourage you people to check your community documents, since it looks like a sloppy work was ongoing this year from the NI side! (and some people might think the non sense info was written by you! (image) )

GDevCon - European Graphical Programming Conference

Tue, 12 Dec 2017 10:39:03 GMT2017-12-12T10:39:03Z

A group of the European CLAs / Champions are in the process of organising a new independent graphical programming (LabVIEW) conference - with the first one, GDevCon#1, taking place in the UK in September 2018.


  • Two day conference

  • Presentations by LabVIEW peers from around the world

  • Run by community leaders

  • Independent from system vendors

  • Focused on real problems encountered everyday by LabVIEW developers

The event is open to anyone (no certifications needed) but it is a technical conference - so it is best suited to those regularly using LabVIEW.


You can visit our website and sign up to our mailing list to hear more about our launch and be first in line when tickets go on sale next year.


We will also be looking for presenters and speakers, please see the website for who to contact.


First mailshot (Week 1):


If you have any questions - feel free to reply, PM me or use the email address on the website.

experiences/feedback from companies - responses to the questions: "why do not you use solutions from NI?"

Wed, 06 Dec 2017 14:51:19 GMT2017-12-06T14:51:19Z

I got interested in what is the penetration of NI "solutions" at different sectors of the industry/ R&D. I see NI products at many places used, but of course there are also plenty of exceptions. I am specially interested in the reasoning, how a certain company decides to use other than NI approaches. I guess senior developers in this forum have plenty of stories and info about such topic, that is why this post! I love to hear stories, anecdotes, etc I do not want to start a debate about which approach/platform/HW solution/software/language is better, but collect/hear info about how nowadays companies decide and reason their selections, for their production and R/D...   Recently I started to more actively search for new challenges (job) from the Q3 in 2018, and I got already some contact requests from head-hunters and companies. During a recent interview, the guy was explaining their profile, their projects and what kind of software and hardware solutions they use. The guy mentioned that they mainly use C#, and hardware solutions based on PIC and ARM micro-controllers. The projects sounded fun what they showed me (physics research involved), and just out of pure curiosity, I asked the interview guy: "have you ever considered solutions from NI at your company?" "You know, I have a CLD and would be fun to develop using LabVIEW if you hire me!". Actually the response was this: "The cost is not the problem, but NI platform/HW is not reliable, and not flexible enough to fulfill our needs". That was the response, and because this topic was not the point of this interview, I could not get more detailed info, even if I was very curious about the reasoning   Beside cost (specially if large system parts need to be changed/"migrated"), I have the feeling that many companies even are not aware of the recent available technology solutions from NI. Maybe 20-30 years ago they made a decision based on that actual situation/technology level, and now it is like "a tradition" that they got stuck with whatever they use since. I do not say any approach is better or worse (often they are even not comparable, as apple to orange...), I am purely interested how they make their decisions, and what is the "inertia" of certain decisions for... For example, I imagine, if I have lots of C# programmers employed, it would be also silly to start using LabVIEW for dev   At another place, when they argued, "NI HW is not reliable, so we do not use it", after some more questions and discussions, I just managed to figure out how to "decode" this response: "we put a beginner/student to develop software using LabVIEW, and we realized the result was a not reliable system!"   At my recent institute: here the story is simple, I understand why our "automation and measurement" group is stuck with Siemens platform: they have experience with it, and to change the huge amount of already deployed Siemens hardware (mainly PLC based control/DAQ systems) in this big facility, could cost serious money. But hey, have you ever seen a recently sold (!!) Siemens PCS7 process visualization software? Crazy bad, GUI is like from the last century, graphing is a disaster, data export is a joke And costs pretty much money! But anyway, this is the tradition here... [...]

Inexpensive LV compatible temperature sensors

Wed, 29 Nov 2017 21:18:07 GMT2017-11-29T21:18:07Z

I thought about posting this in the LV form, but no boards really seemed to match other than this one.


Anyway, I'm working on a small home project for my father.  You see, he has a greenhouse in the middle of nowhere that he uses to garden in the middle of winter.  Keeps him sane!


As a gift to him this year, I want to set up a wireless (preferably) temperature monitoring system because sometimes it gets too cold at night and kills off some of his plants.  I'd like him to be able to stick temp probes in the ground and have it transmitted back to a computer in his house so he can monitor and log.


I was initially thinking K-type thermocouple wire for the sensors.  Cheap, inexpensive, can go back to some DAQ box in a shielded area of the greenhouse so that the actual electronics were protected.  But, I'm having a hard time finding a reasonably priced DAQ box that I can rig to transmit back to the house. 


Thoughts?  Suggestions? 


By the way if everyone wants to turn this into a home DAQ/Automation using LabVIEW thread I would find that very interesting (image)
I have a whole pile of projects I want to do in my next house.


LV OOP small tutorials and introductions in a "workshop style"

Sun, 19 Nov 2017 09:10:14 GMT2017-11-19T09:10:14Z



Previously somewhere else I mentioned I am still a "classless" LV developer. In the last couple of years I could not find a single resource which could push me over "my barrier". Most of the resources I do not find "comfortable", or I feel big part of it just wastes my time or bores me (like the self-paced online training for OOP, with those sound player demo stuff). I am sure the problem with me, I guess other programmers are fine with the available resources...? (image)


So what I am doing recently, I try to collect together small pieces, smaller tutorials/workshops which give me usage ideas how I could use OOP in my projects in a helpful way.

One small example is here:


I have some more complex and advanced sources for later "digestion" (here and here), but I feel I should play with small tutorials first. My question is that, are you aware of resources of simple small tutorials, or even complex ones but with a step-by-step nature to build up more advanced examples?


Right now what I am thinking of which parts of my projects (or my personal User Event based frameworks) could benefit from using OOP. I imagine, my recent intercom User Event/Queue/Stream messages (consisting of an enum/string and a variant) could become Classes. The immediate benefit as I read somewhere, would be that the msg data parsing errors could appear during compile and not during runtime (if I try to use the wrong data type for the "variant to data" function). Another big improvement would be to create a "RS232 class", since my projects use lots of different vacuum sensors, flow controllers, etc, all with very similar feature set and serial request/response communication scheme...


Thanks for any hints and advices! (image)

Since I will have some free time coming up, I have been thinking about getting into computer vision.

A post on the LabVIEW board by Bob Schor about using $80 Logitech webcam got me to thinking whether there is a cheaper alternative to learning computer vision without investing in NI Vision software.

Does anyone have experience with OpenCV?

This is "Veterans Day"

default label position, is your OCD happy with that?

Thu, 26 Oct 2017 15:51:36 GMT2017-10-26T15:51:36Z

Whenever i make label visible for a wire, my OCD kicks in, and I have to move one or two "clicks" the label upward. So the default position for me a little bit unaligned, not in the perfect center of the wire... (image)


Actually is it possible to change this default position in a config file or something?
