[Webinar] Introduction to the Actor Model & Getting Started with the Actor Framework for LabVIEW

On Demand Webinar with LabVIEW Champion, Tomi Maila

If you are a frequent user of LabVIEW, then you’re probably already familiar with Actor Framework, the standard tool that has shipped out with LabVIEW for many years. Knowing how to maximize this tool though, is another story. The learning curve can be rather steep as it requires a paradigm shift in thinking on how to architect applications. We’ve created a new webinar with one goal in mind: to help users feel more familiar with the Actor Framework and actor model.


Join LabVIEW Champion and JKI partner, Tomi Maila in a 40-minute webinar as he introduces you to the fundamentals of the actor model for software development and how the actor model allows you to create robust and modular applications in an elegant way.

Tomi will take this theory into practice by showing how to create a simple actor-based application in LabVIEW using the Actor Framework. He will guide you through the basic components of the Actor Framework and how to effectively use them.

Join Tomi to learn:

  • What is the actor model for software development
  • How to architect applications using the actor model
  • How to launch and stop actors in the Actor Framework
  • How to add public methods to your actors

Duration: 40 minutes

Announcing the New “Magic Delay Fairy” Tool for LabVIEW

JKI is pleased to announce the release of the new Magic Delay Fairy Tool for LabVIEW,  a revolutionary new tool for LabVIEW developers working to solve some of the toughest system timing and synchronization challenges.

Here’s how this tool can help…

Some Bugs Need Fairy Power

Let’s say you have a bug in your code shows up as an intermittent problem. Often times, adding a perfectly timed delay into your code can cause the problem to go away… almost like magic.

.                                           DelayMagic Delay Fairy

For example, say you’re configuring an instrument’s voltage range (sending the “CONF:VOLT:RANG 0,10″ command)  and then querying a measurement (sending “MEAS:VOLT?”). Sometimes the voltage is out of range and sometimes it’s not — the instrument gives you a beep, letting you know it’s not happy. In this situation, inserting a “magic” delay between your configuration and measurement steps might help.

Here’s a video that shows what we mean…

Before Magic Delay: Code is not working! :(

Before Magic Delays

After Magic Delays: Code is “working”! :)

Magic Delay After

How does this tool work?

The Magic Delay Fairy fixes race conditions in your code by inserting magical delays into your code that are specifically tuned using advanced magical algorithms to fix your race conditions. Don’t ask how it works, because it’s magic.

Warning! You may be so excited by this great tool, you may want to prance and frolic.

At JKI, we are on a mission…

At JKI, our team has spent a great deal of time over the years thinking about what it is we do, for whom, and why. Now, I’m proud to publicly announce JKI’s official mission statement!


Our mission has, naturally, permeated all of our work and resulted in a lot of happy customers who call us back over many years. This mission has also resulted in many significant technical contributions to both the high-tech industry and the state-of-the-art in LabVIEW.

More about our mission

JKI is located in the San Francisco Bay Area and serves start-ups and advanced R&D groups within high-tech companies in Silicon Valley and beyond. Fast-moving technology companies hire JKI to help them get their innovative products and technology developed quickly. LabVIEW and the NI Platform are tools we use extensively to help make this possible. Additionally, we employ software engineering best practices and tools in our work with LabVIEW, such as object-oriented frameworks and architectures, fully-automated software unit testing and executable builds (continuous integration), source code control, issue trackers, and Agile development processes.

These tools and techniques enable rapid development; the ability to iterate and change the software quickly as the requirements change. This helps JKI’s customers to continue to innovate and evolve (or even pivot) their product throughout the R&D process.

Are you building a next generation system or high-tech product?

If you’re in need of a team to help you build a next generation instrumentation system or product, give us a call — we’d love to chat with you about your project.

CLA Summit 2013 Europe: “Public Events for Modules” Video & Slides Now Available

I had the pleasure of being invited to speak at the CLA Summit Europe 2013, at NI France in Nanterre (just outside Paris).  This was a fantastic event and it was a lot of fun to meet CLAs from around the world (and especially Europe) and learn from them about this year’s theme: Interprocess Communication.  The food was also terrific — I’m just sayin’ :-)

My talk, titled “Public Events for Modules,” was about a technique for Interprocess Communication in LabVIEW using Dynamic User Events as a core aspect of one’s software “modules” (classes, libraries, components, or whatever modular programming style you’re using in your LabVIEW applications).

In addition to showing how to expose Dynamic User Events for your modules, I showed some of the ease-of-use benefit this technique offers to both developers and users of software modules.  I also show some of the caveats and gotchas of this approach.

This was a really fun talk to give and I hope you enjoy it!

Here’s the video of the presentation:
