My wishes for a "better" Labview

Here's some improvements I'd really like. Not sure where to post them or send them to, so I'll post them here for now.
Add to container
Currently, there seems no way to add things to a container. Well, there's the subpanel, but you can add (insert) only a (one) SubVI.
I've been fighting with this for quite a while, trying to create a flexible plugin structure. I think most widget toolkits have containers and ways to add to / remove from them dynamically. I was rather surprised not to find it here. I suppose there's a real good reason not to do it, but that doesn't stop me from wanting it . This would probably also mean some new containers, like a horizontal and a vertical container or something.
Improved "Clean up diagram"
- Clean up just one programming structure instead of the entire VI
- Exclude certain programming structures from clean up
- Stuff inside a "decoration" should stay inside it when cleaning up. Rearrangin inside the decoration ok, moving out of it not ok.
- Related: Attach comments to block diagram objects (when cleaning up the diagram, they get lost now)
That's it for now, but I still have a lot of Labview to learn so I'm sure more will follow later .

Adding multiple VIs into one container is a very good way to get programming errors. It is like adding control on the fly...

Wish for next version Labview - group of references created

Everytime I create large Labview application, I tend to create constant references and control/indicator references for every controls and indicator, before grouping them tinto clusters and wires so that i do not have to search for it high and low. But the problems is that I find it very tiring. For example, I want to create a group of references with labels for the group of controls/indicators with just one click.
Same for nodes too.
Clement

Maybe it is higtime you began using clusters at design time of your large applications.
Or I suggest you to think of redesigning you application itself.

Is SilverLight compulsory for running a Labview program?

Hi,
I am using a computer on which Silverlight isn't installed (the microprocessor doesn't have SSE instructions so I am not able to install it). While installing Labview 11 I got a message saying SilverLight isn't installed. I will test my labview program tomorrow (recording analog inputs with a Labjack U6 unit (usb connexion)).
Could anyone tell me if in this particular use of Labview (recording analog inputs + savind data to a file) SilverLight is compulsory?
If needed, here is the computer :

IWeb Bugs and a wish for the future. :)

Hi there,
Two issues that I've found moving my photoblog to iWeb, and I'm wondering if they are bugs or issues that the community knows about:
1. I've changed the template I used a lot - font colours, background, etc. Now when I create a new blog entry, it uses the old, standard template and I have to change everything again. Is there a way to make iWeb realise that I've changed my "default" template settings so all new entries remain the same? It seems not. This is my feature wish.
2. Related to this, I solve this problem by just duplicating one of my existing pages and then changing the photo and content and date. The PROBLEM with this is where i think the bug exists. In iWeb, when I click Next/Previous, it goes between the different entries in chronological order, as expected... but when it publishes to .Mac, the next/previous buttons are really messed up, linking to articles/pages that are not even close to being near them in order. I've been able to determine that:
a. Create three new entries in iWeb. Works good.
b. Duplicate the middle entry, put it LAST in the order.
c. The NEXT button on this new, last entry links to the third item, just as the original 2nd item did before I duplicated it.
Is there any way to make iWeb re-calculate the next and previous buttons before you publish it? Or even better, any Apple folks around that can confirm/escalate this?
UPDATE: It's also possible that iWeb is ordering the next and previous buttons based on the time the entry was created in iWeb, rather then the time specified on the entry. If you are porting older entries from a previous blog, this can be a pain because you're not necessarily putting entries in from oldest to newest.
Either way - the behaviour isn't as expected: next and previous buttons ordered by the date specified in the iWeb 'Entries' window.
3. This is more advanced, but seems a bug none the less. I use .Mac publishing, because it's integrated and easy. But I also have my down domain, which I have configured to just "forward" to my .Mac folder. So, when someone goes to www.mydomain.com, the server connects to web.mac.com/me/iWeb/ and makes the request, translating the path. This works really great (save some initial headaches with character encoding), but comments in iWeb blogs don't work when you do this.
They work directly when you go directly to .Mac, but something about the comment system requires that the client browser accurately present the URL to the .Mac server, and in my case, it's reporting my domain name. As a result, when you click to add a comment, you get a "there has been an error" page and it dies.
If this little annoyance could be fixed in a point release version of iWeb, that would be AMAZING.
4. Lastly, one more wish for the future. .mac domain hosting. Domains aren't just for businesses - lots of people have them for their blog/photos/etc now. If I could make my domain point to my .Mac web hosting without any messy translation, I'd be in heaven. I don't even care if I only get my single e-mail address on the domain - just the hosting would be so excellent.
MacBook Pro 1.83 Mac OS X (10.4.6)

It sounds like it! I ported about 10 new posts from my old MovableType installation last night and am seeing the same behaviour - duplicating entries definately breaks the chronological order of next/previous.
Apple?
Is there a place I can file a formal bug report?

On installation of Firefox 4 beta, it tells me that it won't run on my Mac. When I go to system requirements, it takes me to a page for Firefox3.6 requirements. Where can I find the requirements for the beta?

The link to system requirements for Firefox 4 beta takes you to a page that gives you the requirements for Firefox 3.6 instead. I assume that the requirements for the beta are different as I can't seem to install the beta on my Macs. Where can I find the beta system requirements?

I never expected Mozilla to neglect the users of Apple's PowerPC (PPC) computers, while still supporting much older operating environments such as Windows XP. So, I should just throw away a $6,000 system, which is still fast and functional, and contribute masses of heavy metals to land-fills because…?
I'm hurt and confused after supporting Firefox for many years — installing and using it not only on my own computers but on most of my customers' computers. Now I have to tell my customers with PPC Macs they can't have a secure cross-platform browsing experience from Mozilla. They'll have to learn to use some other browser, or buy a new computer.
If one doesn't buy a new computer every year, one doesn't deserve Firefox 4. This is sort of sounding more like a Microsoft™© doctrine. (But wait, I can still have Firefox 4 on a ''SERIOUSLY CRAPPY WINDBLOWS XP pile of rubbish?!'') Please open your eyes Mozilla. This just doesn't make sense.

How do I add a comment to a cell in Numbers for iCloud beta like I can in Numbers for ios???

I can't be the only person to find it incredibly frustrating that it seems impossible to add a comment to a cell in beta. I use this function a lot on my ipad - is it really not available in beta?? And if not, why not??

Hey lolitajoon,
Thanks for the question. You are correct, comments are hidden from all iWork apps when imported to iWork for iCloud beta. Please note that the current release of Numbers for iCloud is a beta version. Therefore, certain features aren’t yet supported.

Looking for a better heatsink help....K8N NEO2

Im looking for a better heatsink....any suggestions? I may oc it but for now I wont....it idles at 40-41 and stays at 60 when im gaming 58 if i turn off cool n quiet.....and thats with some ocz ultra5 Thermal compund....ThX

Yes, agree with SAB, zalman 7000 is a good one, however I´ve got 2 very simular K8N Neo2-systems but with 2 different cpu coolers.
One with zalman 7000alcu and one with Thermalright XP-90 and a zalman 92mm fan ( you can use what ever 80/92mm fan you like high speed, low speed, led colored, etc).
Both are equal regarding cooling to my experience, but I prefered the XP-90 because I did not have to remove the backplate ( I think zalman recommends mounting it´s own backplate to get the right distance/pressure between the cooler and cpu ).
With the XP-90 you just switch the retension mechanism which is easy ( even with the MoBo in the case ).

DO's & DONT's for a better application performance

I am very new to tuning. What are the sql & pl/sql do's and dont's and best sql & pl/sql practices for a better application performance?
I was told by somebody to check explain plan for tuning db & sql statements. But i am bit confused by seeing the explain and don't know from where i have start and what i have take into consideration from explain plan to improve application preformance?
Can somebody help me in this regard?

> I am very new to tuning.
Good. Not having to tune means that the code is performing as it should.
And this is THE MOST IMPORTANT CONSIDERATION.
Do not write and design code that needs to be tuned and twisted and modded in order to perform. Write and design code with the core requirements of that code being:
- performance
- scalability
- flexibility
- maintainability
Good design = good code = good performance
No amount of tuning can turn bad code and a bad design into a well performing and scalable system. Which is why I dislike the concept of "tuning code". Start with a good and solid design. In other words, tune that before the code.
> What are the sql & pl/sql do's and dont's and best sql & pl/sql practices
for a better application performance?
The 1st basic rule is actually quite simple.
The "data layer" rule: Maximize SQL. Minimize PL/SQL.
Do not do in PL/SQL what SQL is very capable of doing. Fact. No other language is faster and better than SQL at crunching data in the Oracle RDBMS.
The 2nd basic rule is a logical extension of the 1st.
The "application layer" rule. Maximize PL/SQL. Minimize Java/C++/C#/Delphi/VB/etc.
Do not do in a 3rd party language what PL/SQL is extremely capable of doing. Fact. No 3rd party language is as capable as crunching data in the Oracle RDBMS as PL/SQL.
Stick to these two fundamental rules and your Oracle application will have a solid foundation for being a well performing and very scalable solution.

Searching for a low-cost plug for doing better slow motion clips.

Where can I find a low-cost or free plug-in for doing better slow motion clips? I produce alot of sports videos and use FCPHD but am looking for better quality. I am not necessarily looking for time-remapping (it confuses the ** out of me). Just want to simply slow down clips and not be as choppy as FCP turns out.
Thanks for any help!

Reference Library for Converting Between LabVIEW and XML Data (GXML)

Please provide feedback, comments and questions on the Reference Library for Converting Between LabVIEW and XML Data (GXML) in this thread.
The latest version of the NI GXML Library is availble in VIPM on the NI LabVIEW Tools Network repository.

Francesco, Thank you for the feedback. With this component it was my intention to make a more "terse" version of the LabVIEW Flatten to XML VI that was also supported on RT and that gave the user more flexbility regarding the structure of the parsing type definition. I think you are right that the XML parser is not compliant to section 2.11 of the XML spec. The parser does specifically looking for a #D#A and this appears to be an oversight on my part. Please confirm for me, the specifcation is saying that the XML parser should be able to recognize three possibilities as an "end of line" character: #D#A, #D, or #A. Am I reading this right?There are more efficient (and in some cases much more efficient) ways of sharing data between LabVIEW and LabVIEW: some examples are flattened binary strings and the datalog binary format. XML is slower than these optons but the upside is that it is human readable. Furthermore XML is inherently hierarchical which is convenient for complex data structures like clusters of arrays of clusters, etc. If you don't care about human readability then you are correct XML doesn't make as much sense.I will return to the GXML source code and try to fix this in the near future but I would hope that instead of creating yet another custom VI from scratch that you could reuse what I have provided for you. I included enough documentation in the source code so that users could make some modificiations themselves. The target application for this reference library was LabVIEW to LabVIEW communication. As such I documented the schema on the dev zone document from a LabVIEW perspective. It includes all the supported datatypes and all the supported data structures (cluters, arrays, multidimensional arrays, clusters of multidimensional arrays, etc.) I do see some value in making a more conventional XML spec but the time investment required didn't really line up with my intended use case. Were there any other downsides to GXML that I have missed? Best Regards, Jeff TippsSystems Engineer - Sound and VibrationMessage Edited by Jeff T. on 04-21-2010 10:09 AM

SpaceX is looking for engineers with LabVIEW experience in Hawthorne CA (LA area)

SpaceX is looking for engineers with LabVIEW programming experience for our Launch group. Our responsibilities include:
Controlling launch pad equipment via PXI/LabVIEW
Commanding and monitoring our Falcon 1 and Falcon 9 rockets via a LabVIEW-based Vehicle control system
Commanding and monitoring our Dragon capsules via a LabVIEW-based Mission Operation system
Ocean recovery of Falcon 1 and Falcon 9 stages after liftoff and Dragon capsules after splashdown
Cargo configuration of Dragon capsules going to resupply the International Space Station
Maintenance of Mission Control Centers with the help of our IT department
With the exception of the launch pad equipment program, most of our LabVIEW programs do not interact with DAQ hardware (unusual, I know). The Vehicle control and Mission Operations software get their data via Ethernet from 'black boxes' that connect to NASA & Commercial RF ground stations. We also create several utility programs in LabVIEW that also don't interact with hardware. So, this is mostly a software gig, not a hardware/software gig.
Ideal candidates will have the following qualities:
CLD-level LabVIEW experience
A good understanding of basic computer networking (TCP/IP, UPD, firewalls, VPN)
Must be enthusiastic about space (What year did we land on the moon? How many men walked on the moon? How many Space Shuttles do we currently have? etc.)
Must be willing to travel. Common destinations include Houston (NASA Johnson Space Center), McGregor TX (test site), Cape Canaveral FL (launch site), Kwajalein Marshall Islands (launch site)
Must be able to work without supervision. We have a very flat management structure, no one will be telling you what you need to do. If you don’t know, ask. If you do know, get it done.
About the job:
Job is located in Hawthorne, CA in the Los Angeles area.
This is not a 9-5 job. There will be some late nights.
You won't be LabVIEW only. Everyone chips in as needed. Our group has done Javascript, C++, MATLAB, configuring of TELEX comm systems, cutting of metal with bandsaws, welding, Unigraphics CAD, etc. If we need it and you don't know it, grab a book and learn.
We are only hiring full time employees. Contractors need not apply.
To conform to U.S. Government space technology export regulations, SpaceX hires only U.S. citizens and U.S. Permanent Residents.
Apply at SpaceX.com. Click the Careers button and fill out the general application. Mention this posting in the cover letter field. Don’t reply to this forum. You need to go to SpaceX.com to get your information into our system.

Please help me with my electrical engineering homework : temperature control and watering system for greenhouse using labview and arduino

temperature control and watering system for greenhouse using labview and arduino
spesification :
1. max temp : 28 celcius (when temperature is more than 28 celcius, fan ON)
2. min temp : 20 celcius (when temperature is under 20 celcius, heater ON)
3. watering system : aquaponic (grow plant and fish in separate tank but connect each other). Plant roots help filter water for fish. Fish poop for plants fertilizer. So I need a pump to distribute water.
Please help me create VI file simulation.. I'm sorry I'm not fluent in English. May God bless you all

Hi,
If you are using the CVI libraries on this you can use the GetCompName() function from the programmer's toolbox. However, your code looks fine, the only thing that you need to change is the data type of the paramenters in CompNameLength. Just declare them using the predefined Windows data types; like this:
LPTSTR computerName;
DWORD compNameLength = MAX_COMPUTERNAME_LENGTH+1;
computerName = malloc(MAX_COMPUTERNAME_LENGTH+1);
GetComputerName(computerName,&compNameLength);
printf("%s",computerName);
free(computerName);
Don't forget to include windows.h where those types are defined.
Good Luck!
