I've been reading a blog called Good Math, Bad Math for some time.

Some (OK much) of the mathematics goes over my head, but the author also takes issue with some ID folks that are crackpots and he takes them to task. He also has some good categories such as programming, graph theory and this thread's primary subject Intelligent Design.

Also, there is a good (and geeky) discussion about Apophis

are the community servers down in Austin or has the files been intentionally deleted ?

The "Community" area on NI changed somewhat in I think Feb/Mar timeframe. I just went to find the new location of the API and discovered that it isn't there. It appears you've been digging and found Qizhen's post linking to the same 'community' forum. Maybe NI pulled it for a reason...

I was surprised because so far the Apple updater only has updated software that was already installed. This seems like a bold (but I like it) move by them to push their browser like this.

If you were still at your http://forums.lavag.org/Unavailable-t8927.html' target="_blank">previous job, you wouldn't have had this "problem"

It reads data from USB port and writes to file in hex format, 5 bytes per line. Could you help me to find bottleneck in the design, please?

I think the problem is that your are reading from the USB device and writing to disk inside the same loop. In the example I provided, I have several loops, data is passed between them via a queue. The logging queue executes at a much slower rate (200 msec intervals) and is not dependant upon the completion of reading from the receiver.

If you use separate loops for your receiver and logger and pass the data between them using a queue, I think you will see much better performance.

Attached is a sample file (.LLB) that I created as an example of logging UDP data at high speed. I've tested this on a P4 3.0 GHz machine with a SATA drive and 2 GB of RAM. I've logged data at 4.9 MB/s with 45% CPU load.

This example does not format the data written to disk, it is binary. As long as your formatting isn't excessive, this technique should work for you.

Welcome to the LAVA forums!

I would suggest that you start by looking at the examples and templates included with the more recent versions of LabVIEW.

You can also refer to the wiki pages here on LAVA, specifically: http://wiki.lavag.org/State_Machine

Who would want to make an operating parameter "anxious" anything? Next thing you know we'll get "nervous" then "paranoid" then "psycho". Then we'll get HAL.

So, transposing an array could look like this:

I was originally going suggest that Bezier wires be passed over and that all wires be replaced with fibers (optical). It appears that http://www.dailytech.com/Sun+Flares+Laser+Interconnect+Technology/article11224.htm' rel='nofollow' target="_blank">IBM and Sun are interfacing CPUs this way. Propogation rates are higher and the loss per unit distance is significantly lower. In your example above, a tight bend radius could damage the 'fiber'. Darren could probably add a feature to VI Analyzer to check for this though :laugh:

Maybe "Jeff's Wire" is actually a fiber?

QUOTE (David_A_Moore @ Mar 31 2008, 11:59 PM)

MGI Heralds Release of Bezier Wiring Toolkit for LabVIEW

Ordinary straight wires force the data to slow down for every wire bend.

New improved spline wires allow the data to flow freely!

Ha! Have you created a dynamic model (using LabVIEW) to evaluate the efficiency of this? It should be easy, considering that 8-10 year olds have developed a real-time measurement system to model and test the flow of their sewer system!

Hi ,I am experiencing a problem with QT Java 6.1 on Windows XP using Java1.4.2 (_2, _3, and _4) where a QT Component (as Component()) created from a Movie Controller placed in a window or frame will sometimes freeze when another window is placed in front of it or removed with set Visible(true/false). I cannot produce a test case or anything of the like because I cannot reliably reproduce it on command. The freeze

occurs on the set Visible () command. Looks like some DEADLOCK. Has anyone else experienced this?

Any suggestions? Ideas ? Thanks.

I see this is your first post to LAVA. Can you tell us how your problem is related to LabVIEW?

LAVA stands for LabVIEW Advanced Vitual Architects. Maybe you are looking for help with JAVA?

And as a seperate comment, I have to say that while I'm happy that NI has gone to such lengths to optimize this stuff under the hood, it seems like a lot of work for little gain in terms of speed\memory usage. As far as I know, the output of any array native that produces a sub-array (i.e., AQ's "stride "array) either goes to another array native, a non-array native, a subVI, or a terminal. If the sub-array goes to anything other than the first in that list, LV has to automatically allocate a full array before proceeding, which wipes out any gain in efficiency.

What happens to array data passed to a sub-vi might have an impact on the way the the http://forums.openg.org/index.php?s=&showtopic=820&view=findpost&p=2100' rel='nofollow' target="_blank">Average 1D Array (Candidate) develops.

I don't want to hijack or move this dicsussion to the OpenG forum, but anyone with some input that will enlighten us (OK just me) would be appreciated.

Is it possible to turn off the feature that automatically posts the text of a previous post when replying to it? For example: take a look at this post

In the post crelf referenced, there are many entries above and below. To reply without quoting, you need to scroll to the top or bottom of the set to select 'Reply'. It's easier to reply where you are reading than to scroll up/down. I've always used the and then immediately delete all the text (unless I want to "quote someone" like crelf ).

The 'tip' for the button indicates that the reply is to that specific entry

I think replying to a specific post has value when using the threaded mode, but that hasn't worked so well and is essentially disabled (although threaded mode does show up now and then on my home computer).

Maybe placing a in front of the and buttons would reduce the "noise". I don't really use or see the value of the button.

The real question for me is "Can he code LabVIEW?"

The list goes on! I think from now on I am going to make an effort to invent new words and terms (like Action Engine ) anytime I get the chance.

Go for it! I've liked the term for some time and make a distinction between it and it's cousins (LV2 global, functional global) in the wiki. I tried, but don't have the stomach or time to argue if such a term is "http://forums.lavag.org/index.php?showtopic=9833&view=findpost&p=40276' target="_blank">contrived". I was pissed for a few days and almost didn't renew my LAVA membership; then realized its not that important. I have decided that I'm no longer a wiki contributor though...

It's amazing how powerful words are, especially when they are used to describe something graphical. If a picture is worth a thousand words, I've "VIagrammed" the equivalent of "War and Peace" at least once.

• "VIagram" - a LabVIEW block diagram image
  
• "VIagramming" - the act of creating a LabVIEW diagram image
  

It also contains the string 'viagra' which should help it's acceptance and Google ranking.

"Thanks for the example VIagram, dude; it kept me up for hours, but now my program is solid and runs for days without crashing!"

Sometimes things get out of order (especially if someone replies while you're replying), so I thought I'd clarfiy

That's why I used to prefer the Outline mode, you could follow the topic graphically instead of scrolling up and down B/T/W I still get the Outline mode on my office PC using Internet Exploder 7. Outline mode is a bit dodgy, but I revert back to it when I have this sort of problem.

As a side note, NI isn't the only vendor with runtime size issues. I just set up a new PC and installed Adobe Acrobat 8.1.2. 30.8 MB for a "reader"?! Why don't we hear more complaints about that?
