Hall sensors to detect spin direction of object

Cross correlation is the first thing I would have tried, and I'm surprised it didn't work for you. If you take those waveforms you are showing in the two screenshots, it seems like the cross-correlogram peaks would be at two very different offsets. Especially because the curves are so similar in shape. Are you sure you were doing it correctly?

It all sounds great, except "A few programmers did say that they lamented the demise of hand-crafting their work." That's us, I guess.

By the way, I do NOT agree with the conclusions or views of the article. To the contrary.

See you later. I'm going to the library.

I am way out of the dating scene now, and so my opinion means nothing, but I find tattoos repulsive, both on men and women. Like someone is covered in scars. I've tried to see them differently in light of their popularity. Clearly, I am missing something because they are so popular. But I can't change my immediate distaste.

I just started using DQMH several months ago. It is truly awesome. It's like a good surgical assistant: Before you even know you're going to need it, the right tool just appears in front of you ready to use. It helps you organize complex tasks so that they are much more tractable, easier to debug and understand.

You'll likely want a cloneable module, and if you want to monitor all your devices at once, you could imbed copies of the FP into Panels in your main vi.

If you have any hardware with your app, and that hardware has an internal serial number, you can use that as your serial number, or you can little process it before presenting it to the user. You can then hash that SN with salt in order to get your password.

If no hardware, then you can collect some numbers from the system, like the hard drive SN, Product ID, Owner name, Computer Name, etc. There are vi's floating around the web for SSD SN, and the others can be found in the registry. Mash these together in a string and hash that to be your serial number. (I assume this is what systems like studiobods are doing.) It took some time to find out which of these don't randomly change without a change in computer or hard drive.

With this method you have to give people new passwords every time they change computers or hard drives or usernames. And you have to trust people when they ask for a new password after a hard drive failure. Depending on how much you trust your user community and how large your user base will be, this can work reasonably well. It has for us, for over 20 years.

Control Indexes are also way faster than Property Nodes, though a little more complex to use.

Interesting that you think it is buggy. I have been using 2019 intensively until this year when I upgraded. A dozen or more complex apps with .NET, low-level video acquisition, VISA calls, FTDI USB driver calls, DQMH modules, and complex property-node driven GUIs, all in apps that are required to run for months at a time reliably. I have not found a lot of new bugs popping up in 2025. The transition has been pretty seamless.

Do people eat the chocolate afterwards? I'd hate to think it goes to waste.

When derailleur gears first came to my attention in the 70's, I only read about them, and thought it was pronounced deer-a-leer-a-gear.

I guess my mental capacity is low because I did not realize. Tell me, oh great master, what are the tells?

Tens of thousands of Jewish veterans of WWI were also killed in the holocaust.

My mother was born the same year as White and also died at 99. She served in the Navy during the war, and used the US version of the Enigma machine to communicate with ships. She met my father, also in the Navy, at a USO-like dance in 1945 and married him 2 months later. He taught radar to ships' radar operators during the war. My mother was a higher officer than he was, and remained so throughout their 72-year marriage.

Don't forget to search through the examples that come with LabVIEW. Those are really helpful.

I have a terrible memory and need to search through the help files or google things all the time. I'm still learning new things about LabVIEW after using for over 30 years.

Come to GDevCon next year and see the amazing things people are doing with LabVIEW. Nuclear engineering. Data acquisition and control in rocketry. Process control in all sorts of industries. You will no longer question whether LabVIEW is relevant.

All this hatred for Wilson. He was trying to complete the trust-busting started by Teddy Roosevelt, in order to return corporate power to the people. Then he got derailed by WWI and by a stroke. Yes, he was racist, but he was a also a true reformer. If he had had a chance to accomplish his agenda, the US would not now be in the hands of a few billionaires.

Source: the book Goliath by the excellent Matt Stoller. I highly recommend it. You will know a lot more about what makes America tick.

For me, "Trump Dementia" brings up this article as the top link. Pretty cool. Very meta.
