Post an idea

It has come up in discusssions that NI does not really cater to hobbyists. A cheap and functional version of LabVIEW is limited to the student edition, which is restricted to a small subset of potential users.

 

 From the  FAQ:


"The LabVIEW Student Edition is available to students, faculty, and staff for personal educational use only. It is not intended for research or institutional use."

 

As a suggested first step, I suggest to remove the academia restriction and mold it into a new product:

 

--- LabVIEW personal edition ---

 

Licensed as follows:

"The LabVIEW Personal Edition is for personal use only. It is not intended for commercial, research or institutional use."

 

 It would be available to anyone for noncommercial home use.

 

LabVIEW currently has the home use exemption that allows installing a copy at home. Unfortunately, if you lose your job, you not only lose your health insurance, but you also lose access to LabVIEW, thus hampering any self paced LabVIEW tinkering that possibly would improve future job prospects. I am sure many retired LabVIEW engineers would love some recreational LabVIEW use. They could be a great asset, because they will have more time helping out in the community and forums. They could even give guest presentations at user group meetings, for example.

 

The LabVIEW personal edition should include all modules of interest to the hobbyist, including application builder, embedded, FPGA, and robotics.  We should be able to distribute built applications as freeware. Support would be limited to community support.

 

Installing LabVIEW on every single private home computer in the world would cost NI exactly nothing (except for some sales of the current student edition which is about the price of a textbook, some internet bandwidth, and loss of the zero to two (?) multi-millionaires who actually bought the NI developer suite for themselves. ;)). 99.9% of users would never touch it, but that 0.1% could come up with great new application areas and would help spread the word on how great LabVIEW really is. Soon 0.2% would use it. 🙂

 

It should follow the "customer class limited" Freemium model, (as defined by Chris Anderson), i.e. limited to personal home use in this case.

 

The running applications should be clearly identified to prevent commercial use. The splash screen and "about" screen should prominently display the words LabVIEW and National Instruments and could even be used for NI advertising and product placements, for example.

 

 

This is not directly a LabVIEW idea, but it is still an idea that impacts many LabVIEW programmers.

 

To keep my distribution small, I distribute my installers without run-time engine and instruct the users to download and install the relevant run-time engine. I provide a link to the run-time download page.

 

Note that these users are NOT NI customers and not interested in any NI products. They are my customers (well, my programs are free) and are only interested getting my programs to work on their PC. They don't even care what was used to develop the program. There is no extra hardware involved. If they already use NI hardware, chances are they already have a profile.

 

My users don't need a NI profile and don't need the follow-up phone call or e-mail from NI, etc.

 

Typical phone exchange yesterday:

 

me: "just click my installer and install the program"

him: "OK, done."

me: "now run it."

him: "OK, ...... error about 2013 run-time engine".

me: "OK, install the run-time engine using the link I sent you in the same e-mail".

him: "clicking the link to go to the run time engine page....

        (..30 second discussion to decide between downloader and direct download...)"

him: "click..(wait for it!)... .it wants me to register..."

me: "OK, let's forget about that. come down to the lab and I will do it for you."

 

End result: more delays (it was late Friday and I was ready to leave), more work for me, more hassle.

 

While gazillions (:D) of registered users sounds good on paper for NI, these are false numbers because many profiles are one-time use and quickly forgotten.

 

I think downloading a run-time engine should NOT require a NI profile. Maybe it should still offer to log in or create a profile, but there should also be a bail-out option similar to "[] I don't want to register at this time, just download the run-time!".

 

 

Note that even better long term solutions have been proposed, but this idea could be implemented quickly and does not even need to involve any LabVIEW developers. 😄

Problem

When creating an installer for my built LabVIEW application, I really dislike having to choose between including the RTE installer (and having a 100+ MB installer for my application) or not including it (and requiring my users to download and install the RTE as a separate step).  Typically, I'll build two installers at the same time (with roughly duplicate build settings): a full installer w/ RTE and a light installer w/out the RTE.

 

Proposed Solution

What would be much nicer would be if my app's installer were able to download and install the RTE, if necesary.  Actually, this is common practice, these days, for users to download a small installer that then downloads larger installer files behind the scenes.

Currently in LabVIEW if you build an installer you end up with a hierarchy of files that look like this:

 

singlefile1.png

 

If you want to distribute this installer via the web, you need to use a third party program to zip it up, or create a self-extracting zip file.  Since LabVIEW can already create zip files with no problem, I propose the ability for LabVIEW to create a single file installer that can easily be distributed, like this:

 

singlefile2.png

 

This can be as easy as a checkbox in the current installer Advanced page:

 

singlefile3.png

When creating an installer for a built LabVIEW application, it is very difficult (see here) to include an additional 3rd party installer (such as a device driver or application that your built application depends upon).  What I'd like to see is a solution that treats 3rd party installers as first class citizens.  I'm imagining a new "Additional 3rd Party Installers" page of the Installer build specification properties dialog.

 

2-3-2010 1-35-27 PM.png

 

This page might look something like the one in the screenshot below, allowing users to add a folder that contains the 3rd party installer files and define a command that is run inside that folder during the install process.

 

2-3-2010 1-41-08 PM.png

 

When LabVIEW builds the installer, it would suck the additional installer folders into the main installer and, after installing your app files and the additional NI installers, it would sequencially extract your additional 3rd party installers into a temp folder and then execute the command line to run.  This is a pretty simple scheme that would really simplify the process for end users.

 

I'm sure I didn't address every issue of this use case, so please, everyone, feel free to add your own ideas.  I'd love to hear your comments.

Yup,  Upgrading LabVIEW versions takes a day.

 

The "Process" today is:

  • Install from media
  • Configure the new LabVIEW.ini
  • install tookits (OpenG, Deploy, VIPM, TSVNtk.....)
  • Mass Compile all them......
  • Fix palatte views... and import and mass compile User.lib\ for here.....
  • Sync glyphs on the icon editor (If the link works......)
  • Add VIT's
  • Add Project Templates
  • Mass compileVIt's and Templates
  • fix "Metadata.xml"...

.

.

Yup, about a day of watching paint dry...........mass compiling, ignoring warnings etc......

"MyLabVIEW" would find all of those customizations and import them to the new version!

For distribution, only package necessary libraries in installer packages built with the project. A lightweight UI, server, or client does not need a full 70MB+ installer that bloats out to a few hundred MB's once installed! A colleague has remarked that the total size of our LabVIEW application+RTE EXCEEDS the entire size of the XPe image running on the embedded computer! This becomes an issue when distributing software upgrades to places in the world without high-speed internet connectivity.

The list of available LabVIEW modules and device drivers is very long. Their names tend to be long too, which is compounded by the many levels of nesting. Modern screens are large.

 

Given all that, why are we selecting software components by scrolling around a tiny window which can't be expanded?

(Note: most of the trees above aren't exen opened yet!)

 

 

Proposal: Make the window bigger (vertically and horizontally), or resizeable, or both.

 

Thanks for listening!

NI send us the NI Developer Suite each year on DVDs all packed in a nice little NI branded dvd carry case. We are on the SSP suscription and we receive 3/years, which means I have a whole stack of them.

 

I suggest that NI start shipping USB keys instead. USB has several advantages:

 

  • USBs are smaller
  • USBs are more usable on devices without DVD player
  • Installing with one large USB means no more DVD swapping. I can go to lunch while NI installs/updates without having to change the DVD every couple of minutes.
  • USBs are reusable: when you get a new version on LabVIEW on a new USB, you can use the old one for regular usage. This also means less waste, since the USB keys are still in use after a new version ships, but the DVDs are useless.

 

Ship developer suite on NI USB keys

I am a big fan of LabView!  This idea is meant to be a positive suggestion, and I hope it will be taken as such.

I almost wish this post was in jest; it is not.  This is a serious suggestion that, in my opinion would improve the NI LabView program, save cost, and be much better for the environment.

 

I recently purchased Application Builder for LabView (both Great products).  I received my Application Builder via FedEx.  It comes in a very nice looking heavy mailing package with the bold label "NI LabVIEW 2010 Add-On Software.  I think there must have been a FedEx overwrap with the following forms:

-Printed shipping manager page with the FedEx Bar Code

-Printed packing Pick Slip (two pages) with a certificate of conformance on page 1 of 2 and a signed page 2 of 2 by the Vice President of Quality and Continuous Improvement (I am not making this up)

 

Now, inside of the envelope is

-The standard folded yellow installation instruction page

-A certificate of ownership! (same serial number as is printed on the outside of the heavy mailing envelope)

-A card which says (really!) "Where is my Media?"  The card says: "In an effort to reduce the impact on the environment, National Instruments no longer ships media with these kits.

 

Now, I assume by this point everyone sees the irony here, and where I am going with this New Idea for LabView!

 

IDEA: Upon successful purchase and proper payment of a LabView Add-On Software package: Email the serial number to the authorized user.

Optionally (if required by legal), send the paper Certificate of Ownership (one page!) to the authorized user, or if allowed by legal, Email a PDF of the Certificate of Ownership to the authorized user.

 

Savings:

Beautiful outer envelope and stack of printed pages made in Ireland - Well, not needed (Give them other work, I don't want to see lost jobs)

Shipping cost and impact on the environment (Ireland to Austin) SAVED

Storage cost and space at NI Austin SAVED

Shipping cost and Air Freight Austin to end user SAVED (less jet fuel impact on the environment)

Less paper to be recycled by end user SAVED, positive impact on less energy needed for recycling!

 

 

Dealing with fonts in LabVIEW can be a nightmare due to the variations in fonts, types of fonts, rendering variations, resizing, etc.  If you are deploying a LabVIEW application on another machine, frequently the fonts or settings on the target machine don't match; creating a very ugly looking panel.

 

When developing for Windows in the past I have always edited my LabVIEW.ini file  to include the following:

 

appFont="MS Sans Serif" 13
dialogFont="MS Sans Serif" 13
systemFont="MS Sans Serif" 13

 

And when deploying an application; I include these in the app's ini file also.

 

This seems to work for most windows targets since MS Sans Serif appears to be a common font.  I suspect this will produce unpredictable results in OSX or Vista for that matter.

 

What I expect as a developer is not having to deal with these font issues.  I expect that when I develop an application that it has the same look and functionality; regardless of where it is deployed; even as a VI being edited on another machine with different font settings.  This means that the font information must be encoded and stored with the VI itself.  I would expect that both the LabVIEW editor and run-time engine would be able to recognize detailed font encoding within the VI and adjust the display accordingly based on the local machines font capabilities.  This is what one expects when printing or viewing an Adobe Acrobat PDF file; and the behavior of LabVIEW code; particularly since it is so graphical in nature; should also be similar.  I wouldn't expect that the actual font bitmaps be stored within the VI itself; but some detailed metrics about the font should be; height, width, kerning, etc.  Thus if a font substitution takes place when being deployed on another machine; at least the text will occupy the exact same extents as the original.

 

Though I don't know exactly what the detailed implementation would be; it does need to be transparent to the LabVIEW programmer, i.e. zero code; zero hassle; zero worries.  It should just work.  I hope we can all agree on this.

For modern application development we need better methods to detect wheter our application is called to open a file.

Currently the only help NI gives is based on command line parameters. And we need to jump through loops to get it working to react on opening a file when the program allready runs.

 

This is a major showstopper in creating professional applications.

 

LabVIEW 8.2 had a hidden event for getting this event, which unfortunatly doesn't work in later versions.

 

 

One thing prevent our company to upgrade to newer labview is that the run-time engine gets too big. Even I really like the features in later version, I still have to save the files back to 7.1 then to 7.0 to build application installer. Under 7.0, the run-time engine is very small, and the installer is less than 10MB and I can easily email the program to customers. In version 8.0, the run-time engine is 65MB and now the latest version is well above 100MB.

 

What I would like to see is that application builder get smart, only pick what is needed and build slim app.

When the Developer Suite DVD binder arrives, the first thing I do is find a black Sharpie, cross out the name (e.g. 2010) on the binder label, and write the version of the software it contains (e.g. 2009 SP1).

 

Rarely if ever do I care which year the DVD binder shipped to me -- all I care about is the version of the software (the most important being LabVIEW) it contains.

 

Now that LabVIEW and most other NI software products are on an annual release cycle and named according to the year and service pack, I would love it if the Dev Suite binders were named the same way.

When installing a new version of LabVIEW, I always find myself resetting all of the options I previously changed from the default settings in the Tools -> Options menu. This means I have to spend my time remembering what options I changed and where in the Options menu I need to change them. It would be nice if a newer installation of LabVIEW looked at the older version's Options settings and then applied those settings to the new installation.

 

The same idea applies to how I configure the palettes on the block diagram. It would be nice if newer installations looked at how I configure my palettes and then set them up the same way. 

 

With these changes transitioning to a newer version of LabVIEW might be even more seamless for users that change their settings from the default settings. 

NI updater kindly informed me that LabVIEW 2014 SP1 was released (even though I uninstalled it shortly after I tried it last year) and out of curiosity, I took a look at the known issues list.

I learned a few interesting things I did not know about, and also that some problems had been reported as long ago as version 7.1.1. This type of stuff looks like bugs that won't be fixed, ever.

For instance, CAR #48016 states that there is a type casting bug in the Formula Node. It was reported in version 8 and the suggested workaround it to use a MathScript Node instead of a Formula Node (where is the "Replace Formula Node by a MathScript Node" contextual menu item?).

Problem: the MathScript RT Module is required. Even in my Professional Development System, this is not included by default. Does this really count as a workaround?

I read: we don't have the resources to fix that bug, or we don't want to break code that expected that bug.

In any case, this bug with most likely never be fixed.

The bottom line is, we can waste a lot of time as users, rediscovering bugs that have been known for a while and will probably never be fixed. As a user, I would really appreciate a courteous warning from NI that there are known traps and have a complete description handily available with the help file related to the affected function.

 

My suggestion: add a list of known issues (with link to their description) for all objects, properties, functions. VIs, etc, in the corresponding entry in the Help File.

Currently LabVIEW only has support for Mandriva, RedHat and SUSE Linux.  What's even worse, only 32-bit versions of those are supported.  Today, 64-bit linux installations are on huge raise, and Ubuntu is getting more and more popular.  LabVIEW Linux support should be expanded to include Ubuntu, and 64-bit versions are needed.

 

cheers,

Hi all,
For a lot of reasons, I have to work with several LabVIEW versions.

My biggest fear is to save something in a later version : projects are quite big, and a save for previous version is hard when using terce parts (such as OpenG, JKI, etc.)

My whish would be to have a warning message when I save a vi in a new version, such as :

"You are saving a 8.2 file in 11.0 : do you want to continue ?"

 

 

Have a nice day !

According to the increasing number of questions about this communication protocol, it would be time to rewrite the MODBUS library. I also suggest to add it to the NI device drivers installer.

 

This could be the place to list the expected modifications. Some comments and bugs are already listed in above linked page.
