  1. Since the Gingerman is no longer in downtown Austin the a consensus has been formed and many of the LV enthusiast will be meeting at BANGER'S SAUSAGE HOUSE AND BEER GARDEN Sunday evening. This is a few blocks from the convention center opposite direction of 6th street. Most people start arriving around 6:30-7 after dinner. Please come by if you are around Sunday evening. Banger's Sausage House & Beer Garden 79, 81, & 81.5 Rainey St. Austin, TX 78701 https://www.bangersaustin.com/#home
  2. I have decide that if more than one class uses a typedef than is belongs to neither so it goes in a common location. I do have to find out all the typedefs that are used before copying a class. But prefer it to the coupling of classes that is created when one of them owns the typedef. Dmitry Sagatelyan's 2018 NIWeek presentation SOLID Actor Programming had an interesting solution to this issue. He creates a application specific translation class. These classes are not intended for reuse and translate outputs from one class to inputs of another.
  3. Thanks for the update. We saw the auto download issue in testing and it appeared to be fixed for Chrome and IE for Windows. None of my testers were using Macs so it is good to get that feedback. I put a note about Firefox in the original post.
  4. Please see this link for Video downloads
  5. he information formally listed in this thread is no longer valid. The site is now offline. All the videos have been moved to dedicated event pages on the LabVIEW Wiki. https://labviewwiki.org/wiki/Events - LabVIEW Wiki https://www.youtube.com/channel/UCUiBucUImKZERoTzaOtHB5g/featured - Youtube Channel
  6. I am not sure what the solution would look like but I would like to somehow combine Dereks solution with the LAVA Code repository. Ideally we would use LAVA for discussion, ranking and finding and Git for code management and collaboration.
  7. LV Champion Derek Trepanier has developed a Git solution and did 2 presentation at the CLA summit I am still working on getting all the CLA videos edited and uploaded. The new Tecnova video sharing site is a week away from going live. So to keep the momentum going I have posted Derek's presentation on the link below so others can see his perspective. https://drive.google.com/open?id=17mjooun62caeL6EcsCG2g1arpg-OoRhk
  8. Thank for the update on the crashing videos I will re format them and look into the issue. Last Friday the old server that we are using crashed and so currently it is down. No videos were lost I.T. is working on a new solution but may take a week or two. NI is also working on putting the videos on their Center of Excellence Vimeo site by June 30th I will post updates when they become available.
  9. Certified 1-5-17 placed in General Catagory
  10. Certified on 09-27-17 and placed in General category
  11. I will look to see what the ban rules are when I logon to the server tomorrow. It will only ban if a logon fails X amount of times and the ban is only temporary and no more than 24hrs. Video 205 is Fab's presentation on technical wealth. She is editing the video and I hope to have it up this week. I will post when it is ready.
  12. Please see this link for Video downloads The NIWeek 2017 Videos are uploaded to the ftp server. Please see this link for information on downloading the videos. https://lavag.org/topic/19154-ni-week-2015-videos/#comment-115444
  13. Also Fabiola and Delacor asked I add their videos to the mix. Videos 201-203 are up on the ftp server and I uploaded them this morning Delacor's videos are also on their youtube channel
  14. New Videos were added this weekend. A few came out fuzzy so I overlaid the presentation slides where I could. Thanks to my fellow Champion Intaris or shoneill for recording the additional videos.
  15. Please see the above link to download the videos The NIWeek 2016 Videos are uploaded to the ftp server. Please see this link for information on downloading the videos. https://lavag.org/topic/19154-ni-week-2015-videos/#comment-115444
  16. Certified June 17 2016 placed in Machine Vision and Imaging.
  17. Certified 06-02-2016 and placed in the Hardware repository
  18. The Tecnova FRC server is back online. Thanks for your patients I've added 3 videos from the 2015 CLA summit that cover features in 2014 sp1 and 2015 2015 CLA_00A_Jeff Kadosky_New Wire 2015 CLA_13_Rob Dye_Profile Buffer Allocation Tool in 2014SP1 2015 CLA_16_Jeff Kadosky_Round Table New Wire Mark
  19. Apologies the Server is down due to a bad UPS battery and a power failure. I will work with I.T. to get it back online this week. Thank you for letting me know I will post when the server is back online. Mark
  20. One of main difference that I see between yours and mine is who is responsible for sending the messages (who's while loop sends the message). In yours you appear to spawn a "distributor" and it receives and distributes the messages to the registered modules. In my architecture the sender does all the work (Through the API) API finds the specific message registry using the name of the message In the registry is an array of all couriers that want to receive the message. The message is placed in each courier and the "Send" method is called So mine requires the sender to create the copies and send the message to each recipient where yours delegates that responsibility to the distributor loop. In MultiQ Because every module depends on the distributor if it crashes or dies then all communication is lost. This is something that I struggled with in previous implementations. It will work and I know of at least 2 other CLAs that use this method but for me is creates an unnecessary dependency in the types of application I build.
  21. Back in 2011 I posted a framework https://lavag.org/topic/14566-message-routing-architecture/ It was inspired by a CLA presentation by Rob Humfeld (Who is the guy that taught me LabVIEW) called JAMA The WOW factor for me was when he open 2 separate vis one generating data and one displaying data. He created a third to detect spikes and ran it without stopping the other 2. The module ran and started receiving the waveform data and detected spikes. After that he stopped the vi made changes and started it back up again without stopping the 2 running vis. This was the type of architecture I was looking for so I took the ideas he had wrapped in an OOP framework. Hopefully the graphics and example code explain the way it works. The power of this framework is modules are totally decoupled from each other and do not depend on any other module. They created, manage and destroy their own courier (transport mechanism) They only receive messages that they register for. Any module can send any message at any time this makes creating simulator quick and easy. I find this framework especially useful when building test systems. Using the framework I will create an asynchronous modules for each major device in the system. These modules will connect to the hardware and monitor health and maintain connection. Next I will create a module that will be called synchronously by the test sequencer. Its purpose is to connect to the async module through the framework request and receive measurements via messages Pass results back to the sequencer Close down This works because the framework allows any module to connect, communicate and die without adversely affecting other modules.

  22. 02 and 03 were combined into a single video as it was a part 1 and part 2 series. 12 has been removed at the presenter's request
