I have a LV8.6 subVI that is set to subroutine priority. It has 6 array indicators that are used for debugging and are not connected to terminals. When I have LV show me buffer allocations, I get flashing dots on these indicators. Given that I'm running in subroutine priority, is memory really allocated for for those?

Thanks,

Gary

Hello all

Recently I was redeveloping application from LV 7.1 to 2009. I noticed that on cursor legend I cannot perform some of the actions - like having currently existing cursor made on free-run or snap it to a plot. These actions were possible with 7.1 without any additional efforts. With 2009 I would have to make it handled in software. I am wondering if it is possible to have it the old way ?

In attachment I put screen-shots of both cursor legends, and the area which interests me.

Thanks for help in advance.

Try right-clicking on the cursor name.

First of all I highly doubt you're famous simply because you linked in my signature (I'm implying that I'm a nobody).

Damn. I guess I'll have to try for a more noteworthy accomplishment.

And to be clear I am not Crelf's alter ego.

I know. I felt a little bad about posting that. First you're being criticized for not being senior enough to post on LAVA, then I make a joke about you not even existing... Sorry. Rough day for Hooovahh's ego (alter or otherwise)...

Yup got my self a new signature.

Woo-hoo! Now I'm famous!

Sorry I missed a couple letters in your name...

And here I thought what was being suggested was some sort of nefarious plot by Senior Management to make the Underling do his dirty work. Tho considering the Senior Management allegedly involved, I can't imagine he'd really want/need someone else to do that. He's always seemed willing to irk people all on his own.

Seeing how this whole topic seems to be related to conspiracy theories, could you raise your "nefarious plot" to "conspiracy theory"? Maybe Hoovah is really Crelf's alter-ego, which he uses to irk people?

I also don't understand what my seniority as a software/electrical engineer has to do arguments on climate change, or even a observation of similar stying posting between two individuals.

I'll take that one further and say that not only is seniority as a software engineer irrelevant to discussions in the Lounge, but also that such seniority is irrelevant to discussions about software engineering.

Are junior people not allowed to voice their opinions? Are they not allowed to have good ideas?

GW/"CC" is too important of an issue for scientists in general and programmers specifically.

Ok, I'll bite. Why is GW/CC especially important to programmers?

I'm totally good with both of those A colleague of mine once said "God doesn't wnat us to be vegetarians, otherwise He wouldn't have made meat taste so damn good!"

EDIT: (how do I embed the comic?)

Right - and even if there's a comment in there that says "fudge factor", if you're just the coder then it might not be your place to question it if your jobe is purely implimentation. Again, I'm not saying that what's happen is right, I'm just saying that there might be more than what we're seeing here.

Didn't I just say that?

Maybe the scientist and/or developer didn't think it would ever be scrutinized - maybe they thought "okay, we know that this is a fudge factor, and is wrong, but we need it in there to get the software and/or data analysis up and running for now with some dummy data, and we'll go back an fix it later, once we've got the real data in", and then it got lost in the haze. Totally true that a better code review and change tracking system with the appropriate processes to execute them would have caught this.

Or the "fudge factor" is a correction to the formulas to get models to match the observed data.

If you are coding something up using "y=mx", with the assumption that all of your data starts at the origin, you might find that "y=mx+b" actually fits reality better. That constant "b" could be called a refinement to the model, or it could be called a "fudge factor", especially by someone who doesn't necessary understand the origins of the equations.

I'm not saying that this is what happened - just pointing out that a "fudge factor" can be used for non-nefarious reasons.

I agree 15 kg is a pretty heavy payload. Our robot is fairly beefy and IIRC has a 5 kg payload. One question to ask the vendors is if they can support a heavier payload if you use slower speeds with less acceleration.

Interesting point.

Also worth noting is that arm-type robot vendors do not typically quote accuracy specifications since the error varies depending on the position of all the joints. They do quote repeatability though, and these robots are very good at going to a position you've already defined the joint positions for. What's this mean in real terms? If you define a known position in the robot software and then tell it to move 40 cm in *this* direction, how close you get to 40 cm is undefined. (Though still very good. I'd swag worst case accuracy is < 1mm, though I have not specifically investigated it.) However, if you manually jog the robot into the desired position 40 cm away, visually confirm it is in the correct location, and save *that* position data in your software as the second point, it will hit it dead on every time.

Our requirement is 2cm, so I'm not too worried about that. We'll also have an external measurement capability that will tell us where it is, so we can then adjust if necessary.

Check with Kawasaki Robots. They make numerous robots that might fit your configuration and are a rock solid robotics company.

A 15 kg payload robot is going to be a pretty big one. As payloads and reach go up, the size of the robot goes up almost exponentially. You could easily be looking at a 200kg robot.

Funny, "exponentially" was the exact term I used when grumbling about the size.

We're looking into rearranging components to get by with a smaller reach and smaller payload.

I'll look into Kawasaki.

Thanks,

Gary

Dak,

Thanks for the lengthy response.

I talked to a Fanuc vendor and it seems that all of their arms (at least the ones that vendor carried) were too heavy and power-hungry for our application. I'll have to start thinking about how I can rearrange components to get by with a lighter-duty arm with a shorter reach. The information you provided will allow me to ask some semi-intelligent questions when trying to understand controllers.

Thanks,

Gary

Use your favorite low-pass filter; that's all that an envelope detector really is anyway.

It may have to be more complicated than that, depending on whether can or can't teal with the reduced time resolution associated with the LPF. Maybe a combination of LPF + peak detection to find coarse position, then peak detection on the raw signal to get finer position.

My mum sent this to me this morning, and I thought it appropriate to share in our current times

Reminds me of when my kids fight.

I've heard numerous stories from people in Canada who have a lot of complaints, mostly due to having to wait for specilized care.

That can be the case here too. I have a friend who's a kidney doc in Oregon. He's in a private practice with 3 or 4 other doctors. Last I talked to him, they were looking to hire another doctor to try to help alleviate the 3 months that their patients had to wait to get an appointment.

Also, some doctors are being driven out of the market by the current system.

• The OB that delivered our first kid had to throw in the towel because she couldn't afford the malpractice insurance. From what I heard, it was cheaper for her to become a stay-at-home mom than a practicing OB (at the workload she was interested in working).
• In the family practice that we see, most of the MD's have switched to concierge medicine in order to avoid dealing with the insurance companies. We now typically see physicians assistants, who are overseen by those MDs.
• Before he switched to concierge medicine, my doctor stopped working with the insurance company my employer used at the time. He told me that it was just not worth it. The straw that broke the camel's back was when he received recognition from the insurance company as one of their "top providers". The next month, he received a letter from them saying that he was providing too many expensive services and all of his claims would have to be pre-approved by one of their doctors. I had to find a new practice until my employer switched insurance providers the next year.

I think all of these are signs that the current system needs some work.

"During my service in the United State Congress, I took the initiative in creating the Internet." -Al Gore, 4/9/1999

If George W. Bush had said the exact same thing the media and the moonbats would have gone nuts and howled in collective glee. Editorials would have gone on for months. Al Gore said this, and whether or not he was taken out of context doesn't matter. He said it. Al Gore was very instrumental in legislation that helped build the Internet infrastucture. Even taken out of context the quote is actually partially true. It just sounded silly and self-serving. That's why I use the quote and make fun of Al Gore for saying it.

I've worked with people who are involved with funding and overseeing development of government programs. They really do seem to have trouble distinguishing (at least in the language they use) between doing the work and being in the program management/funding chain. I've heard people say "We have experience with X". When you ask questions about that experience, it becomes clear that what they really should have said is that they performed programmatic oversight of someone who was doing X.

I think it's not terribly unlike the people who have used LV-build apps and think that means they are experienced LabVIEW users.

Let me Google that for you.

Yeah, I found them and a few others as well. I was wondering if anyone had any personal experience with any.

are you building a sammich maker?

Yes, 15kg ones.

Sorry, this topic is not controversial enough for the LAVA Lounge. Where's that "Report to Moderator" button...?

But Yair brought up a politician! Doesn't that count??

Sorry.

No need to apologize. I did the same thing in this post.

Can anyone recommend a 6-axis robotic arm with about a 1m reach and a payload of about 15kg? The lighter the better.

Thanks,

Gary

what are the goods of having multiple kids vs one or even none?

My wife and I both come from pretty small families. We felt like we were missing out by not having larger family networks. We wanted to give our kids the opportunity to have more family with whom they could celebrate with, communicate with, etc, especially as they grow older and (hopefully) have their own families.

Plus, the more we have, the higher the likelihood that one of them will take care of us when we get old

Has anyone created an envelope detector?

Envelopes are typically rectangular, and have little triangular flaps with a strip of nasty-tasting glue. You just need to pattern match on that

Sorry. Couldn't resist.

I have a theory that the total work involved in raising children is a function of the factorial of the number of children you have, though I admit I chickened out after #2 and didn't sufficiently test my hypothesis.

I've got 3. I think the curve actually bends the other way - I would say that the increase in workload per additional child actually goes down as you add more kids. As you have more, they start being able to entertain each other and the older ones are able to help out with the younger.
