  1. You need to feed it a snack every now and then - it gets hungry on long journeys...
  2. My gut says "BAD. Prone to abuse." I'm going with my gut on this one. What if the required output type changes, and it's way downstream? You won't get an error until you run. This should be a development-time error, not a run-time one. (Also, anything that AQ calls "magical" scares me )
  3. Found it: http://geekandpoke.typepad.com/geekandpoke/2010/05/one-day-in-the-life-of-a-coder-part-6.html
  4. Yeah, I figured the loop iterations were already running as fast as possible (with your standard test string, there are only 8 iterations total anyways right?). I'd forgotten/not noticed that the VI was set to subroutine priority. My suggestion above about chopping the boolean array saves a huge 224 bytes!
  5. I was curious about buffer allocations for the reversed array too. One of the things I tried was to force sequencing of the two case structures, rather than having them run in parallel, but nothing I did had any effect on the speed, even with a very long test string. However, if you pop up the buffer allocations display tool it does show a dot on the output of the reverse array node. I never looked into profiling memory usage. I also tried iterating backwards from the end of the array, but this was significantly slower than just reversing the array and autoindexing. I'd say all of this is
  6. Well after about an hour of trying the only thing I could come up with that wasn't slower was to delete all but the first 32 elements of the boolean lookup array constant, since every character greater than 0x20 is not whitespace. But given that this didn't seem to speed up things at all, only saves 224 bytes, and further obfuscates the code, it's probably not worth it. Nice code Darin. Jaegen
  7. I can't add anything to ned's reply, but did want to mention that a common mistake to watch for (I make it all the time, and you even made it near the end of your post) is to type 198 or 162 instead of 192 and 168. Does anyone know if there's a psychological basis for this error? Seriously, what is it about these numbers that makes them so prone to mix-ups? Jaegen
  8. <nitpick> Something about the upgrade, and perhaps the theme LAVA is using, is causing the text of a post to be indented slightly around the user info/avatar section. It only shows up if there's enough content in the post to reach below the div, like dannyt's post above: Here's what it looks like if I click and drag to select content in Chrome: You can clearly see that the border around the "author-info" div is forcing the post content to the right. Obviously not a major issue, but it's a bit distracting. Otherwise, I love the upgrade. </nitpick> EDIT: My pictures didn'
  9. We use CSV files a ton (too much) here too, but be warned: CSVs don't like Europe (or Europe doesn't like CSVs) - any country that uses commas as a decimal separator can't use commas as a column separator. After being bitten by this years ago all my text logging code allows for a re-configurable separator and file extension. Jaegen
  10. Well, since this is kind of the "Don't use classes in your CLA exam solution" thread, I figured I'd chime in with my $0.02 CDN now that I've passed... I spent a long time thinking about whether I'd use classes going in to the exam. I received strong advice from a few people not to, but also bought into Steven's statements above about his experience. In the end, I decided to go with classes for 2 reasons: Firstly, because I'm now way more comfortable using them than not using them (and I hate the sample exam solution's use of "action engine"-type VIs, with tons of non-required inputs), and s
  11. And I passed! Woo hoo! I suddenly feel like a member of an elite cadre of hard-core developers. That or a loosely defined herd of NI-brainwashed nerds. Same difference... Now to convince management to send me to the CLA summit ... Jaegen
  12. I'll bite: I'm going through the rather tedious process of porting our test stand code over to yet another version of test stand. Essentially, this means I'm re-creating low-level I/O code to feed into the underside of our hardware abstraction layer, but since the I/O list looks mostly the same as an existing one (but of course never exactly the same), it means a lot of copying, pasting, and typing until things look right. This is particularly painful when I'm keen to start testing out LV 2011 and all the new and interesting things I saw at NI Week. Oh well, maybe next week ... Jaegen P.
  13. According to Justin there are no actual tickets. I think the list of attendees is stored in his brain somewhere. Jaegen
  14. This sounds like it might be the Mac version of the problem discussed on the JKI forums here. You should make sure that you disable all anti-virus type services before trying to install VIPM. Jaegen

    Technical Sessions

    Looks like they just released the scheduler. Here's the direct link: https://sine.ni.com/...tmp2=niweek2011 Here's the link to the community discussion in case the direct link doesn't work for you: https://decibel.ni.com/content/message/24924#24924
  16. Thanks for the insight AQ. I wasn't implying type defs should change - just asking whether the "don't add type defs as data members of a class" rule changes if the type def belongs to the class. If I open the class and modify the type def, doesn't a new version get saved to the class mutation history (since its data type has changed)?
  17. Is the class mutation issue the only reason to avoid using type defs as data members? And does the mutation issue exist if the type def belongs to the class? (In this case, the class is guaranteed to be in memory when you edit the type def.) I've never had issues with type defs in class data, but I haven't really used the mutation history feature, and I don't think I've ever used a type def as a data member that didn't belong to the class (other than simple, unchanging things like enums).

  18. "about 1.2 miles" ... sure you can't get any more accurate? You're right though, according to Google, it's only "about" 1.0 miles from the north-west corner of the convention centre. If survival isn't guaranteed, what is?
  19. In the spirit of "pay first, ask questions later", now that I have my ticket ... Is transportation provided, or do we have to get ourselves to the restaurant? Can't wait to meet everyone there. Jaegen
  20. Sorry, but kludging is the only solution I've ever found for this problem (edit the control and use an appropriately-coloured rectangle decoration over the 118). Jaegen
  21. Don't forget - if all you want to do is use "Get" and "Set" instead of "Read" and "Write", you can just modify the default values for the appropriate controls on "...\LabVIEW 2009\resource\Framework\Providers\LVClassLibrary\NewAccessors\CLSUIP_LocalizedStrings.vi". That being said - this is a great addition that will make automatic updating of the icon possible. Thanks, Jaegen
  22. It appears that the RSS feed is having trouble handling rapid replies to a thread. I've seen a few times now where I get the answer before I've read the question (I'm using Google Reader). This thread was the most recent. Jaegen
  23. Thanks for the hard work to everyone involved in restoring LAVA - we couldn't do without it. Jaegen
  24. is very happy to have LAVA back

  25. Dude, slap on some dorky glasses and that would be me as a kid. Almost the exact same setup (though I never had the disk drive melt a table cloth). Jaegen
