NI Certified LabVIEW ARCHITECT, NI Week Winner, Author of the LabHSM Toolkit

Thank you for your interest. I already posted here, but since the header of the original said "Certified Developer" and I am a Certified ARCHITECT now, I decided to post again.
If you need a LabVIEW developer, you will find that my resume which is attached, outlines why I am an excellent fit for a position with your company.
In addition to my broad educational background including two Masters Degrees in Electrical Engineering and Physics, numerous Computer Science courses taken, and twelve years of diverse experience in programming, system administration, and support, I am a National Instruments Certified LabVIEW ARCHITECT. As you can see on the National Instruments website, there are only about 50 people worldwide who were granted this title. I have a history of numerous successful projects in the areas of industrial automation, control and data acquisition. In particular, I have implemented several LabVIEW test systems projects including the following:
- Real-Time Natural Gas Mixtures Characterization System, based on near infrared absorption spectroscopic data for Gas Technology Institute;
- Real-Time Electron Beam Doses Monitoring, Beam Parameters Measurement, and Ion Charge Measurement Systems for Steris Corporation (NI WEEK 2003 BEST APPLICATION CONTEST WINNER in R&D/Lab Automation Category);
- Control and Data Acquisition Program for an Electron Spectrometer System in the Western Michigan University Accelerator Laboratory;
- LIMS II (Temperature Test), Surge Test Automation, Locked Rotor Test, Variable Ambient Chamber Control and Data Acquisition systems for Underwriters Laboratories (UL);
- Abrasion Wear Test for Caterpillar;
- Distributed Data Acquisition and Reporting System for Hydraulic Spray Nozzles Testing for Spraying Systems Co.
It was me who created LabHSM (http://labhsm.com), a toolkit for advanced event-driven development in LabVIEW. It allows creating complex applications as a collection of active object type components that have uniform structure, but different purposes. Each component runs independently providing services to other components and exchanging data via standardized queued messages. The resulting code has the same structure and looks similar regardless of specific functionality. It is easily readable and modifiable by developers other than the author. LabHSM implements the powerful paradigm of hierarchical state machines (Harel/UML statecharts) and has a separate specialized editor for defining component behavior on a higher level of abstraction.
I also have done several projects involving HMI, digital I/O, motion control, communication between a PC and PLC's, using Visual Basic, Think & Do, Steeplechase and other software tools.
My experience and background enable me to master any software development tool quickly, making me a perfect candidate who can always keep up with the ever-changing world of computer technologies.
I am looking forward to discussing this opportunity with you.
Sincerely,
Stanislav Rumega, CLA

An update: I am still in Milwaukee, Wisconsin, USA. The current client ran out of projects for me,
so I am ACTIVELY looking now. An updated resume is attached. If you are in US and any farther from me than Chicago, relocation assistance is highly desired.
Again,
I am so fed up with US immigration "process" (almost NINE years here LEGALLY and green card is nowhere in sight!) that would SERIOUSLY consider UK, Australia, Canada, EU if somebody is SERIOUSLY willing
to help with the papers and relocation.
An updated resume is attached.
Recent achievements:
1. A couple of test stands for testing high voltage (15kV, 27kv, 38kV) high current (up to 100A) reclosers. Those devices are used by electrical utilities companies. They are made by Cooper Power Systems. It's sort of a big three phase breaker but with the brains - it's own computer. Very sophisticated device. It is programmed at which currents and for how long to wait before opening the circuit, when and how many times to try to close it again before locking out, etc. See http://cooperpower.com/Products/Distribution/Reclosers/ for more info on.
2.Updated the David Boyd's famous Tunnel Wiring Wizard to make it work with LV 8. See LAVA forums: http://forums.lavag.org/index.php?s=&showtopic=211&view=findpost&p=9207
3. Created a Property and Method Selection (PMS :-)) Assistant to simplify access to undocumented (private) properties and methods in LabVIEW 7 through 8 - very useful for anybody experimenting with VI Scriping features. Again, see it on VI Scripting LAVA forum:

Version 1.1.1 of LabHSM Toolkit for Complex Event-Driven Development in LabVIEW – Small Corrections and Huge Changes in Licensing.

A new version of the unique toolkit is now available for download. As announced earlier, LabHSM makes it possible to easily create and then maintain complex event-driven applications in LabVIEW as a collection of HSM-driven active object VIs using a higher level of abstraction and agile software development methodologies. These active object VIs are created based on a universal Hierarchical State Machine ( HSM or statechart ) template. Therefore, all your code looks similar regardless of its functionality!
So, what’s new in version 1.1.1?
The code (made in LabVIEW 7.0 for Windows) now comes complete with block diagrams (password protected).
Simpler debugging code in the full template.
Extra menu items in the editor to open VIs as well as HSM files - nice to have when the LabHSM editor is the only VI open.
Copying of default actions is now implemented correctly.
No more run-time licenses! Just buy a developer's license once and distribute as many applications as you like!
The "Demo_" prefix is no longer required for VIs created in the trial version.
No more nag messages while running your HSMs!
As before, the LabHSM toolkit is available for UNLIMITED PERIOD trial. Please visit http://www.labhsm.com for details and download. The site also contains references which you may want to check to learn more about hierarchical state machines and active object computing.

New LabHSM Toolkit - Agile development of complex event-driven maintainable LabVIEW applications with active objects / actors based on a universal Hierarchical State Machine / statechart template.

Dear Fellow LabVIEW programmers:
Most of the systems you deal with are reactive. It means that their
primary function is constant interaction with their environment by
sending and receiving events. But most likely, they can have something
happening inside them too, even when they are not processing messages
received from outside. So, such systems have to continuosly react to
external and internal stimuli. Right? Moreover, most likely, they
consist of subsystems that are reactive too and, in turn, can have
their own "life", to an extent independent from other parts (with
which they still communicate, of course). Reactive (event-driven)
systems are more naturally modeled with active objects. So, why then
should we try to model and code them with GOOP and its passive
("dead"!) objects?
"Flat" State Machines have been known for decades to have severe
limitations. It's been more than 20 years since Dr. Harel invented
Hierarchical State Machines (statecharts) to fight those limitations.
Then why does NI still tout the same old good Moore FSM as the
ultimate tool for event-driven programming in LabVIEW in its $995
State Diagram KIt?
The LabHSM toolkit we are happy to present, makes it possible to
easily create and then maintain complex event-driven applications in
LabVIEW as a collection of HSM-driven active object VIs using a higher
level of abstraction and agile software development methodologies.
These active object VIs are created based on a universal Hierarchical
State Machine ( HSM or statechart ) template. So. all your code looks
similar regardless of its functionality!
We all love just jump to code, right? However, to be good boys, we
need to do design first. Then implement it in code. If the logic is
modified we need to redo the design first and then redo the code. When
using LabHSM where behavior information is abstracted into a separate
HSM data file editable with a supplied editor, there is no need for
coding separate from design any more. The modified behavior becomes
code automatically as soon as the HSM file is saved. Design is code!
The implementation basically follows Dr. Samek's Quantum Programming
paradigm. (see http://www.quantum-leaps.com). However, as already
mentioned, LabHSM stores the behavior information in a file separate
from the code itself. It also adds state dependent priorities to
events, a separate queue for public events/messages, and, of course,
some LabVIEW specific code like capturing front panel user events and
putting them into the private Events queue. Communication and
instantiation functions are also rather specific for LabVIEW.
It is available for UNLIMITED PERIOD trial. Please visit
http://www.labhsm.com for details and download. The site also contains
references which you may want to check to learn more about
hierarchical state machines and active object computing.
Since this is our debut we will appreciate any comments and
suggestions. Our contact information is available on our site, of
course.
Have a G'day!

Certification Nugget: CLAD - Certified LabVIEW Associate Developer

About the CLAD Exam:
The clad_exam_prep_guide_english.pdf states that "A CLAD demonstrates a broad and complete understanding of the core features and functionality available in the LabVIEW Full Development System and possesses the ability to apply that knowledge to develop, debug, and maintain small LabVIEW modules." In other words, you should be able to to string LabVIEW functions together into meaningful LabVIEW code in accordance with LabVIEW best practices. You are mostly book-learned, but can develop and maintain small VIs, updating them as necessary.
The test itself is a one-hour multiple-choice exam with a passing grade of 70% and is available at Pearson VUE testing centers or NI branch offices. You'll get something to write on, and something to write with, in case you have to work out some problems.
NI Preparation Information:
The Certified LabVIEW Associate Developer (CLAD) Exam Preparation E-Kit is National Instrument's official CLAD exam prep kit. You will find links to their exam prep guide, practice exams and other helpful items.
My Journey to become an NI Certified LabVIEW Associate Developer:
After quickly reviewing a sample CLAD test, in May of 2013 I walked into a test center, took the test and passed. Simple, huh? In truth, it was the culmination of about seven years of preparation - although I hadn't thought of it as such back then. It was all about visiting the NI LabVIEW Forum at least once a day, even if I had no questions to ask. Sometimes I just combed the forum looking for interesting topics. If I didn't understand something, I wasn't afraid to ask questions. I wasn't afraid to defend my position. (And occasionally I was even right!) Eventually I found that I was answering questions as well as asking them. My next question to ask was to myself: "Why not try the CLAD test?" So I glanced at a sample test, realized it felt more like a review than a test, walked into a test center, took the test and passed.
The reason behind my getting certified was to have something on my resume to compete with LabVIEW developers that had twice as much experience - or more - than I did. Seven years of experience may seem like a lot, but it's not.
Since then, I had become a CLD. With the CLAD, I showed that I knew basic LabVIEW concepts; with the CLD, I showed that, not only could I talk the talk, I could walk the walk. (The CLA shows that you can talk the talk and walk the walk, all while chewing gum and juggling a few chainsaws.)
My Personal Recommendations to Candidates:
This section will be a bit different than the corresponding sections in the other certification nuggets because there are really no specific strategies to doing well on the test other than know how to do well on a multiple choice exam. Instead, I will focus how to gather the LabVIEW knowledge necessary for you to pass the exam as well as discuss the path forward. That being said:
Check out the CLAD kit for sure, but I cannot stress enough the importance of being a regular visitor to the NI LabVIEW forum. The LabVIEW Gurus live there. Ask questions. Ask for clarification. Fill up from the information fire hose. If you're like me, it will only make you thirstier.
Follow the tutorials listed here (at the bottom, Looking for Free Training).
If you own a copy of LabVIEW or have LabVIEW installed at work, check to see if there is an active SSP. Oftentimes your employer doesn't even realize that the license includes free online training and is very glad to let you make use of it. Just make sure you get permission. It is their license, not yours. With the SSP you can take the online equivalents of the LabVIEW CORE classes (1,2 and 3) as well as a host of other courses.
Get the LabVIEW Home Bundle! It's the LabVIEW FULL Development system - for $50! You can't use it for commercial use, but heck. FIFTY BUCKS! Nothing like learning by doing.
Use the CLAD as a stepping stone to your CLD. You got your CLAD to distinguish yourself from the crowd only to learn that having a CLAD is like being a second lieutenant in the army. (Hint: The army is full of them.) Study hard and get that CLD! Become a senior officer! Show the world - and yourself - that you are serious about LabVIEW!
Comments?
I hope you found this nugget to be useful. I invite you to share your CLAD experiences: "The thrill of victory and the agony of defeat," as it were. To the candidates: Study hard. Soak up the wealth of information from the NI LabVIEW forum. Fear not the CLAD test.

gregoryj wrote:
I've been hesitant to take the CLAD because I've read that it really doesn't mean much, and should not be taken if you don't intend to take the CLD. In my current position, I never work in a team (on software) or make very large applications, so I'm not sure my experience would prepare me for the CLD.
While it's true that it is a stepping stone to the CLD, it can also be used as a measuring stick to see how much you really know about LabVIEW. I actually think it could benefit you greatly because it will really make you start thinking "LabVIEW" if you haven't already. It's cheap and it's a short test. It could be a wise investment.
Plus, many places I've interviewed for give you a few questions right out of the practice exams to gauge your experience level. If you show that you're a CLAD, they may waive that test. In fact, some LabVIEW houses have been known to take a CLAD and train them up the a CLD - and pay for the test!

Watch the NI-Week 2009 Presentation: Updating the LabVIEW Error Handling Core

The resources for the "Updating the LabVIEW Error Handling Core" NI-Week 2009 Presentation are now online.

I have always gone the latter route when I needed it. I usually use an action engine to keep track of the error messages. Said action engine can be used to combine and suppress errors, as well. I have posted an example below (LabVIEw 7.1). In this case, the error propagation is occurring in a task handler which is processing multiple command/data pairs. The command is set at the beginning of the task and the error handler is sprinkled liberally throughout the task code. In this particular case, the desired behavior is to continue execution on error, but log the errors.
I prefer this type of method because it gives me complete control over the error propagation. It has the down side of requiring more code and effort, but I think it is worth it. I like functionality to be explicit on my block diagrams. It makes long-term maintenance much easier.

LabVIEW 8 does not close ref's the same as LabVIEW 7!?!

Hello!
I have been struggling with a difference between LabVIEW 7 and 8 in how the Close Reference functions for Active X objects. In order to fully understand the problem, let me first explain the process of how I got here.
I have an application in beta testing and we noticed a huge memory leak in LabVIEW 8, 8.2. I took a snippet of the code and worked on it a while to reduce the memory leak. I was closing every reference and could not explain it so I wrote the same code in VB and saw no memory leaks. I implemented the same code in LabVIEW 8 and still saw a memory leak. The code opens a graph control from a third party vendor and draws it. Each time the graph is drawn in LabVIEW 8, it costs about 30-40k. We have 8 graphs in our application bringing each iteration to 240-320k. The users are going to be reviewing between 96-384 samples in one sitting but we have no control over when the program quits. 384 samples reviewed in the graphs is 92,160k as a minimum. I was frustrated and about to send it to the thrid party vendor, AB Sciex, but they only had LabVIEW 7.1. So I converted it back to 8.0 and then to 7.1.1. I ran the code in 7.1.1 and there were little to no memory leaks! I even tried it in LabVIEW 7.0 and it worked the same as 7.1.1.
I monitored the memory of LabVIEW through the task monitor in Windows XP. I have tried it on a few XP machines and a 2000 machine and same answer on all. I also built a Task Monitor tool using .NET to graph the memory of the LabVIEW process. I verified that running the .NET example as an exe and the windows based task monitor behave the same and produce the same result.
So, I have an example that works in VB, LabVIEW 7.0 and 7.1.1. but 8.0 and 8.2 cause memory leaks! I have tried numerous things to force the removal of the references but nothing seems to have worked. Here is a list of things I have tried in LabVIEW 8 to force the closing of the reference:
- Error detection after each property node/invoke node to catch any errors for the mem leaks
- Deallocate Memory function is placed in every VI.
- All VIs running in the User interface thread to avoid thread collision, also tried running in the IO thread.
- Debugging turned off on all VIs.
- All references converted to controls (instead of constants) and made not visible on the front panel. I hoped this would not force an update to the FP or memory.
- All Open and Close references are in seperate SubVIs for memory deallocation.
- Time delay of 3 seconds in between each property node/invoke node to make sure deallocation can occur.
- Forced recompile and saved all. Rebooted in between all attempts and changes above.
- Put all code and ocx control in a SubVI and called it through the main program as a SubPanel. I can see memory deallocation, but its not a full deallocation. It deallocates about 40k, but the load eats up 80-90k. VB and LV7 deallocate about 20k, increase 55k for the load, then drops 30k after the load and results in about 3-4k in memory for LabVIEW.
I am hoping through this post that someone can help me out with understanding why LabVIEW 8 would handle closing references differently than that of LabVIEW 7. I feel as though i have attempted nearly everything I can to get LabVIEW 8 to work with this example. I have an open reference (ha thats funny) with NI to look at this but wanted to see if any of you had any thoughts? Thanks!
Try it out for yourself here please....

Thanks for the reply,
On the first issue, I believe this made sense as it made no difference, but was a recomendation from NI so I tried it.
On the second issue, I just put in a close ref on the input to the Variant to Data function. This ensures that the reference being passed iin will be empty. The Variant to Data function only creates a new instance of the type of reference being passed in. At this point in the code, the reference has already been closed from a previous VI and I am only using it as a type, as I know it doesn't replace the reference. This was a good check though and looked at all my other variant to data functions just in case but still the same results in LV82.
Third thing is that I tried the profiling tools but it didn't offer a way to track active x data or the memory leak at all. They offered me how much average memory and max they used.
thanks on the fourth. I put in some extra error dialogs now there in case something does happen.
As far as the error detection VIs, they work very well for what I need them for. I like to put in unique error tags in each VI. So long as the error check VIs are in place after each routine, I know exactly where the error occurs because of the error code. So when an error occurs, a dialog box comes up with the LabVIEW error code, VI path and unique error code. It also provides an option to debug which is very cool. It will open the vi with the error and pause it. Then open the block diagram and turn on the light bulb and wait for you to unpause it. This lets you see exactly where the error happened so you can come back to it. It also can record it to a log file or ignore all errors of this type. There is still some things I need to do to it, but its been a work in progress over the years.
What boggles my mind is that the code has no memory leak in LabVIEW 7, 7.1 but has a loss of 40-50k each iteration i LabVIEW 8,8.2. If you have any other suggestions, I am certainly open to trying them.
I am currently investigating a subpanel option to encapsulate all the active x code in another VI and calling it dynamically. Its too early to tell how much this will change things, but I believe the memory leak is because the ocx control of the graph on the main panel is not being released because the main VI never goes idle. If this is true, then the ocx control will be forced to close and deallocate memory because of the dynamic call. When I have the results, I will post em.
Thanks!!

Can I sell books made with iBooks Author in the UK iTunes store?

Hi all,
I'm a UK-based musician who publishes a range of tuition books on playing the bass guitar. I've spent the last few months devleoping one of these books in iBooks Author, and the end results are really impressive. I submitted the book to the iTunes store last week (after setting up a US Tax ID etc) and it was approved in the US store yesterday. Here's a link to the relevant page:
http://itunes.apple.com/us/book/bass-players-guide-to-scales/id534940432?mt=13
My question is, is there any way I can make this book available to customers in all countries? I filled in all the info/pricing etc for all countries when I uploaded the book, but it's only approved for sale in the United States so far. Is there just a delay in the other stores being approved or can it only be the US for textbooks? I notice that the UK iTunes store does not have a textbooks category. Am getting worried now that I shouldn't have put it in the Textbooks category, although I don't remember being able to choose another option.
Any help greatly appreciated!
Cheers
Stuart

It is possible to publish books created in iBooks Author outside of the US. They will just not be able to appear in the Textbooks category as it's currently a US only category.
I can see in the UK store that you've got two editions of the same book for sale. One has screen grabs and is clearly filled with iBA features for £9.99 and the other at £6.49 with no preview images which I assume is in standard ePub format - both are in the Arts & Entertainment -> Music category.
Congrats!

Is it possible to run Labview ver 6.5 with PowerPC as the target CPU and VxWorks as the target operating system? If version 6.5 does not support this configuration, do any of the later versions support it?

I have an Ada executable that's creating a buffer of data that's being fed to a Labview executable that's displaying the data in a GUI. We're re-architecting some legacy system hardware and I'm just trying to figure out if this configuration is even possible.
Thanks

Hi,
I never heard of LabVIEW6.5. I only know of LV6i, LV6.1 and LV7.0...
Why don't you just call your next/regional NI sales rep?
