  1. These attractors show sensitive dependence on initial conditions so it shouldn't be to far of a stretch to call it inadvertently generated. Part of my collection of computer generated art I have done in LabVIEW.

  3. My best friend runs the Large Scale Systems Museum in New Kensington, PA. I should have posted this last week when I received it but better late then never. If your in the area feel free to stop by. Most of you have heard of the Large Scale Systems Museum, a public museum in the Pittsburgh area that is focused on minicomputers, mainframes, and supercomputers. LSSM opened its doors to the public for the first time in October of 2015, coinciding with a city-wide festival. We have been doing tours by appointment since then, averaging 3-4 tours per month. On April 30th, there will be another such festival here in town, called "New Kensington Better Block". It's a large block party that will encompass much of the downtown area. There will be more than sixty street vendors offering food, handmade crafts from local artists, and just about everything else you can think of. There will be two stages' worth of live music, games, a beer garden featuring great brews from the historic Penn Brewery, lots of kids' activities like face-painting and caricature artists, drawings and raffles, the grand openings of three new businesses, and lots of other great stuff. Another star of the show, Pittsburgh-based C/PMuseum, as a guest of LSSM, will also be returning to Better Block with a special exhibit this time covering the history of the world's largest technology company, Apple Computer. From the humble beginnings of two friends named Steve, through today, Apple's 40th anniversary. See running examples of the actual machines that launched Apple in the 1970s and 1980s. In addition, the gaming wing of C/PMuseum will feature a display with running examples of game consoles from the earliest generations through the most modern 3D immersive virtual reality. Where else can you start out playing on a Magnavox Odyssey, and end up inside the VR world of an HTC Vive? The C/PMuseum pop-up at New Kensington Better Block, that's where! The LSSM will be participating in that event just as we did last October, by being open to the public all day. (I'm aware that this is very short notice; for that I apologize) Many of the Very Large Computers here will be running and demonstrated on a rotation throughout the day. Come and hack on DEC PDP-8, PDP-11, and VAX systems, IBM System/36s, and everything in between. See Cray supercomputers, DECsystem-20s, IBM System/370 and System/390 mainframes, and real rarities such as a Symbolics Lisp Machine, and minicomputers from the 1960s such as an HP 2116B (one of their first!) and a Varian 620-L. See a Heath H-1, a tube-based analog computer from 1956. See nearly all of the IBM "midrange" line. See how SSP, the operating system from the IBM System/36, can run in a virtual environment on an AS/400. See what an 800-pound hard drive looks like. All are invited! The LSSM is located at 924 4th Avenue, New Kensington, PA 15068, right in the middle of the block party area. New Kensington is about ten minutes' drive from the Allegheny Valley exit of the Pennsylvania Turnpike, Exit 48. It's a very easy area to reach, and there are a number of decent and inexpensive hotels nearby. I hope you can make it. Once again I apologize for the short notice. And of course if you cannot make it, feel free to contact the LSSM via email to info@lssmuseum.org or on Facebook (search for "Large Scale Systems Museum") to set up a visit at your leisure. You can also see some photos of our first big public opening on that page. Please feel free to forward this message to anyone whom you think might be interested. Thanks, -Dave McGuire President/Curator, LSSM

  4. Here is some rhetorical response: Scan with what element? I presume you mean the color sensor thing? So do you intend that the sensor will move in relation to the barcode (like down the linear axis of the lined barcode? Or do you have a camera in your system somehow? What is the formatting of the code you wish to read? There are many different encoding schemes of linear bar codes. Its important to know which scheme the code you intend to read is encoded using. I would think that at a minimum, one could find the spec for the encoding you wish to read, and write code to decipher that standard, of course, in the absence of a better way. Lets see what others offfer as well. USB Barcode scanners with the encodings in the hardware of the scanner are available for cheap. They use laser that you point down the axis of the barcode. My understanding of their operation is that they are able to determine the encoding standard used automagically and simply return the content of the code via USB.

  5. If you answer why you haven't visited in 2 years then that will probably be the answer you seek. Not sure what you mean by "cool" discussions. If you mean things like LVOOP then, personally, I don't think it has anything to do with LavaG being past it. LabVIEW stagnated over 5 years ago and all the subjects have been talked to death and everyone has written and debugged their frameworks (as they were in other languages 10 years before that). There were really only a handful of contributors (AQ, Daklu, Shoneill .... and now I'm struggling) and the only one that still visits to contribute is Shoneill, I think. Generally, though the lack of LabVIEW innovation is the main reason there are less "cool" discussions generally. The thing that made this apparent to me was when a 15 year old technology (Vi Macros) was suddenly re-discovered and piqued everyones interest. There was then a flurry of contribution and excitement (especially me) that brought me out of answering implementation questions and sparked my need to investigate and explore - something that probably hadn't happened for a couple of years on LavaG. So new "cool stuff" isn't being discussed because LabVIEW isn't developing new "cool stuff". VI macros ended with the development of "Named Events" and that is "Cool" with a capital "ICE" If Lavag.org goes then I will not be going over to ni.com. I never post on ni.com and probably only visit it 2-3 times a year if Google gives me a result in the top 5.I got tired of it demanding to know the inside circumference of my colon just to log in and the quality of answers is nowhere near as adroit or concise as on here. You know how after 10 years of programming when you have a problem that would be a 10 minute fix if only you knew x, y or z? So you phone up NI and manage to get through to an application engineer then spend the next 4 hours explaining your problem and them passing it on to someone that actually knows, waiting for their response then replying back. Three days later of this back and forth and they finally escalate your query and you get to talk with the actual person that knows and they tell you "Oh thats what you wanted? x=2, y=4 and z=8". Thats ni.com! In this analogy, LavaG is where ni.com escalates the query to. So don't think of ni.com it as a competitor. Think of it as a filter for studenty and mundane questions

  6. On NI Forums I give help, on LAVA I seek help. I post a lot less than before but I still have a look at all the new topics and read those that relate to what I do. Very often when I - or someone around me - has a LabVIEW related question, I remember of a topic I saw on LAVA and give the link, the amount of great advice/help available on LAVA is huge. Couldn't live without it!

  7. LAVA is still my number one place to go find answers. I am more of a lurker though... I would be very sad if LAVA were to disappear. LAVA needs to stay.

  8. I got that too in Chrome. Thought to wait and see again later. Still an issue, So decided to clean my cache and voila!

  9. Freelance/consultancy help needed at our Southern California location. I have a project where I need to take an existing LabVIEW solution and adapt it to make the application FDA 21 CFR Part 11 compliant. The application is a machine vision solution using the Vision Development Module. The vision part is working well and doesn't need to be replaced. The system uses machine vision to inspect pharmaceutical injection components. I'm looking for an engineer with experience in developing, qualifying and validating Part 11-compliant systems, including the addition of audit trail and data integrity functionality. I wrote all of the original LabVIEW code so you would be working directly with me to implement the solution. I work at Amgen, a large biotechnology/pharmaceutical company based just north of Los Angeles. I have a preference to work with engineers located within reasonable driving range of our facility, however due to the niche nature of this project we can probably be somewhat flexible with distance. If you are interested please contact me and I will call you to discuss the project in more depth.
