  1. It seems like a sad commentary that a backup system can't just blindly backup your data.
  2. What?! That must be a first! I don't think I can recall a discussion ever coming back on-topic after meandering off into the philosophies of LabVIEW.
  3. I'm staring at that trying to figure out what makes it "sarcasm"
  4. Interesting... I just tried this, and found that disabled controls are semi-transparent. I hadn't realized that.
  5. Of course! That makes perfect sense! Maybe if I want to see if LabVIEW has a built-in thesaurus, I should try right-clicking on the pi constant. Incidentally, we're missing a "sarcasm" emoticon.
  6. Thanks for all the advice. I agree with Daklu that it'd be better to try to show them something that captures their attention than to try to teach them something. An electromagnet would be a good demo too.
  7. Maybe this awareness shows up during the teen years. That's why teens have a reputation for being difficult - they are trying to reconcile their past and current lives.
  8. Don't think we have too many of them here in Northern Virginia. We have politicians instead.
  9. Oh, I hadn't thought of magnetism. That would be good. I guess we can't do the demonstration that was done in my college physics class. It involved a red wagon, a fire extinguisher, and a long hallway.
  10. My daughter's kindergarten class has parents come in and talk about their jobs. Since data analysis seems like it would be hard to explain to kindergartners, I thought I'd talk about some of the things that physicists study. I also want stuff that doesn't require that I go out and spend a fortune on props. I had a few ideas: Simultaneously drop a softball and ping-pong ball (or maybe a crumpled-up paper) and show that they fall at the same rate (Galileo's thing). Have kids rub balloons on their hair and show how they stick to things. Maybe this: http://www.kidsmakes...icles/show/fedm EDIT: Simple machines would be good too - particularly levers. I may only have about 5-10 minutes. Any other suggestions? Gary
  11. It is doable. Right click on the Y-axis numbers. Select Duplicate. Select one of the axes. Right Click. Select Swap Sides. Wire your inputs into a Bundle. Wire the bundle into the terminal for your chart. Go to front panel. Expand he Plot Legend so you can see all three plots. Right click on line in legend, select Y Scale, and choose which axis you want that data to use.
  12. try 'cmd /C' (without quotes) in front of your command string.
  13. If I remember right, you need to put a cmd in front of your command in the LabVIEW call. There might be a switch that's needed after it also. Sorry I don't have more detail - not at work yet. edit: Did you check the Calling System Exec example?
  14. Factor of 6-10, depending on data properties.
  15. I think that those of us who are logical thinkers and tend to be more pragmatic would not be interested in doing things just to score political points, which means that we wouldn't get very far in politics.
  16. But all the other values are correct?

  18. You are averaging 2 per day. Shaun's at 2.4. If I wasn't so lazy, I could write a VI to predict when he'll surpass you. Or I could be like a textbook author and just state that the exercise is left to the reader. EDIT: To whomever is currently writing this VI (I'm sure someone must be), we'll all be really impressed if it automatically updates based on current post count and post rate
  19. So, if I understand you right, you are currently using "hired guns" (i.e. the programmers who don't have any other involvement in the project), and you want to replace them with free labor by making the grad students work on their own projects as part of their research? I would tend to agree with Shaun and Cat that you may run into motivational/attention-span issues. The programmers that you're hiring are doing the work because they choose to. Would the grad students be able to choose whether to work on the software themselves (vs. having you do it), or would it be a compulsory part of their research? Also, you mentioned having hired the programming students for 10-20 hours per week. If the students are already taking 7 years to finish their PhDs, do they really have time available to take on the additional programming/learning without extending their time to completion by another year or so? I think this could work if your grad students are really interested in doing the programming. Your chances of success also probably go up if you allow their programming tasks to take advantage of the subject-matter expertise that they are developing as they do their research. You are obviously passionate about your programming work, as evidenced by your describing learning LVOOP as "fun". Remember that the grad students are equally passionate about their research topic but, as Cat's friend said, might not care much about the instrumentation that provides them with their data.
  20. Congrats ShaunR! At this rate you'll catch crelf by the spring. Gary
