And I had to work to get a score that low!

Thanks for the replies!

Yeah - it's amazing what you can do when a pressure like a budget is removed as a limitation to innovation. It's a pity that the motivation came from war-mamed guys/gals in the first place.

So a new-born infant is not in an optimal state?

It is by interaction with our surroundings that allow some to achieve the higher state?

...You can hear that? If so, you've got a much better ear than I do (and I do play a bit).

No I can't hear it but I seem to be able to sense it somehow. In my "other life" I am surronded by musicians and find myself often bombarded with talk of diminished 7th and pentatonic scales. It is usually about that time that I wonder off into the other room and check the forums because before long they start playing the game of "Lets turn the music way up and start yelling at each other."

But back to the topic.

I have given more thought to the four vs five finger rendering and am inclined to believe the artist wanted to give the goat guy a greater humanlike nature (hands are supposed to by one of the harder parts to draw).

Why would you think goats were chosen to represent the the protagonist?

I am curious what you have to say about this Q since goats were used in many interesting passages of scripture. Daniel's "goat with two horns" and one of the apostles wrote of "seperating the goats from the sheep". In the culture I grew up this often taken as seperating the bad (goats) from the good (sheep). But the rebel in me makes me question that meaning. I thought the goats were often kept along with sheep because the sheep were dumb and would follow each other off a cliff, while having a goat around the sheep would follow the goat. So I wonder if that passage really is intended to reference those that blindly follow the masses vs those that question the action of the mob.

The card sharkster appers to have morphed into the donkey between scenes, they could be one and the same.

OK, that is my last series of comments and observations before you pull back the curtain.

Is anyone clear on the language of the song?

The guteral sound is what made me first think Frnch but if its not french then maybe its hebrew. When I double clciked on Yair's link the YuoTube page had hebrew replies (since (I think) hebrew occationally imbeds words within words I don't know enough to be able to use my hebrew-english lexicon). I had once read that all hebrew music was written in a minor key (is that an over generalization?) so this music passes that test.

SO now I want to think this is a story of Isreal.

The swimmer represent those that choose the remain in the diaspora and the suit goat represents those that returned. The pursuit by the whale repesnts the persecution by the christian ( water is used to symbolize baptism) (trying to live according to Mosaic law in christian countries).

The card sharkster was that counsel by the allies after WWII that decide they would create Isreal. (Side observations: Most cartoons hands are rendered such that they have only four finger (three plus thumb) the goat guys have five. ???)

The mule was the US and Great Britain who encouraged the creation of Isreal and fostered the migration. The mule did not aide in the final work and the suit goat had to do it alone.

After making the leap into nationhood and then passing by fire (military action) the emerged as a small country. The end scene where the goat and the mule look at each other sorta says "So now what?"

Am I getting any closer?

I just counted them up (for the first time ) and I think there are seventy-nine different avatars on the shirt. That should be roughly the top 100 LAVA users (in terms of post count), minus a couple dozen who don't have avatars set, plus Spoolie.

Thanks to Michael for sending me the raw user & avatar information I needed, and special thanks also to my friends , , , and .

Note, also, that due to Internet Magic, you can customize your shirt on ! There are several different cuts & colors of shirt available, for various prices.

Great job lads ! :thumbup:

Thank you Chris and Justin :worship:

No CAR available.

A future version of LV will give broken wires for this code construct.

Hello, this Question in not easy, but:

which programm architecture do you use in your projects if you use very much parallel loops, which communicates with syncronisation tools (Queues, Notifiers, User Events and so on)?

Thank you, Eugen

I am involved in the design of many of the applications that come out of my office. I have taught my developers to first evaluate the applications needs before deciding on an architecture. I do not believe any two application have left our house that use the same architecture.

App Design in 15 minutes (an obvious oxymoron)

1) Understand the requirements of the app. Create a diagram (model) that illustrates the various responcibilties and the interaction between any cooperative entities.

2) Give the entities descriptive names and list their actions.

3) Define the data used to in the inter process communications.

4) Evaluate the naute of each interaction (these are data paths). 1-to-1 1-to-Many, Many-to-1, etc. Also concider failure scenarios, and performance req's. A high data rate app may require multiple CPU's work cooperatively to keep up with the data stream.

5) For each of the Data paths, identify a comm mechanism that will meet the req's. If possible use built in mech's queue, notifier, etc. If no "out-of-the-box" sync mechanism fits the bill, then design a custom one. In the case of customs I favor AE types but will use others.

So I guess the answer to your question is I use all of them and sometimes invent my own.

Have fun,

Ben

This routine is useful to check on the location of all VI's in your project. I generally use a rather simple structure without dynamically loaded vi's so it works for me. It's written in LV 7.0

The problem it is aimed to solve is to ensure that you are not linking in vi's from other projects, and that all your vi's are in their expected places.

John

Hi John,

This is indeed usefull in LV 7 and previous, it's cool to share it !

If you switch to LV 8 you'll see that the LV project window has great new feature to see where are the VIs called in a project. :thumbup:

Its not French then?

Leviathan?

Its was involved in both scenarios but only one was pursued by it.

The scene were you can see that the one in the suit was the one that choose his card seems signifigant.

It work great. I pass from 20fps 60% of CPU to 30fps 10% of CPU it's much better that way.

Thank you all for the reply, and thank you Norm for the hack

Ben's comments remind me a couple of books I read, I don't know if it coud be related to religion or more globaly to spirituality but the wales (or sometimes daulphin) makes me think of something of that kind.

My understanding of this video is not clear in my own mind, at first it left me kind of sad and after wiewing it a couple of times I felt chilled out and - not faithfull but - hopefull.

I couldn't say why

You can use IMAQ Draw from IMAQ Vision. As far as I know IMAQ Vision license is not required for this function.

I can't use IMAQ because i'm using a beta version of LabVIEW

Some one knows about an activeX or dotNET control that can display images at a higher frame rate then the picture control. Currently I use the picture control to display 2d array of RGB value (32bits) as fast as I can, but I use Flatten Pixmap.vi and it takes 30ms to process my 640x480 image and it take a lot of CPU time. Is there other way to do this?

Thanks

I don't understand the langauge usd in the music.

The video aws well done. Like the the movie "Brazil", after viewing it multiple times I came away wondering "What was that all about?"

I liked the shadow of of the grim reaper with head on the skull (about 2:30 into it, using a shadow to fore-shadow) as well as the whale swimming bewteen alternating trees. If pressed I would have to say its the story of two friends that have taken two seperate paths. One to short term pleasure followed by enternal flight from a whale dispatched by an under-wear clad congregation. The other took the less pleasing path that ultimatly culminated in his death and resurection. The signifigance of the donkey still evades me. It was an asset in much of the journey but could not carry him the final miles, although it was there to great the resurected.

Now it is my turn!

What do the words say?

How did you find it?

No. It is perfectly legitimate to store a LVClass in any functional global, including action engines.

What I suspect you've read is my ravings about a better way to write the action engine itself using LVClasses. That new, revised action engine still stores data just like the ones you've written for years, and it can store any LV data, including LV classes. But it is more extensible and reusable.

If my guess is right, you think you've read "LVOOP is an alternative to AEs" when what I have said is "LVOOP provides an alternative implementation for AEs".

I can't express in words how happy I am to read your reply. There are tears welling up in my eyes because I am actually starting to "get it"! Maybe this emoticon will help illustrate.

QUOTE (Omar Mussa @ Jun 11 2008, 11:19 AM)

I assume that by Action Engine you mean you're using a functional global inside your LVOOP object. What it sounds like you are doing is trying to create a By Reference framework. Search for LVOOP and By Reference or ByRef. There's been a lot of discussion on LAVA related to this topic.

The short answer, creating ByRef objects using LVOOP (ByVal) objects is not defeating the purpose of LVOOP. There is even a shipping example that shows how to do it (ReferenceObject.lvproj).

Thanks Omar,

I can see how that can be used if I can create my object at the start then fork the wire to feed two loops.

In my case, objects will be coming and going. In the end I think I will end up with at least three parallel threads running, one for each of;

1) read from real-world source and update each object with a new value

2) Keep screen updating at 10 Hz

3) GUI, user can add new or toss old objects. Also can change attributes of any widget.

I am attaching a zip of what I have so far (warning memory leak is due to how I implemented the re-drawing. Will fix this latter).

This is what I have so far. My top level VI has two loops, 1) Screen updates, and 2) Handle "mouse down" events to add new widgets.

The screen updates use the AE to invoke "Update Image" methods and widget that have a new image get re-drawn then picture is updated.

When a mouse down event fires a new widget is added to the collection inside the AE and a the Image Change flag is set true.

So I am still wondering if I am going the wrong way with this.
