Noooo, I didn't clarify enough.

Represent your axes with the actual angles. These probably correspond to motor position or revolutions.

Use the quaternions only when you want an orientation for these angles.

Maybe you want to know in which direction the PTU is pointing for a particular set of motor positions, or axis angles. Compute the kinematic chain by multiplying the quaternions corresponding to each axis in the order they are physically applied, but multiply from right to left. Your final result is one quaternion representing the direction the PTU is pointing at. (You could also use 3x3 matrices or other representations) Depending on your physical configuration one of the Euler angle variants (Tait–Bryan angles is another term to search for) could perfectly describe your case and you could just use these to store the angles and compute the orientation.

If you don't actually need the final orientation, then you can omit the quaternions altogether.

If you have orientations as input and need to control the motors so the PTUs are pointing in the required direction:
I would compute the current orientation of the PTU. Then compute a trajectory of quaternions interpolating from the current orientation to the target orientation (use quaternion slerp for interpolation).
Then at each timestep you compute the required motor positions using inverse kinematics [1].

It is a common problem that multiple motor positions are possible and actually an unfinished research problem.
Now that I wrote this, I think this might be the problem you are encountering.

For PTU I think it would be ok to try to recover the current target angles from the target quaternions of the trajectory using one of the Euler configurations. There are papers [2] listing all together, so one can try which is correct.
Having a configuration chosen there is still the problem of multiple solutions. In this case use the one closest to the actual current angles. For cases when all angles are possible for an axis, use the current angle as target (i.e. motor doesn't change). When you then have an target angle use `wrapToPiSeq` to get an equivalent angle close the current actual angle as input for the motor controller.

In computer animation and robotics, inverse kinematics is the mathematical process of calculating the variable joint parameters needed to place the end of a kinematic chain, such as a robot manipulator or animation character's skeleton, in a given position and orientation relative to the start of the chain.

If judges don't listen to private groups challenging the government, then we are in a world of trouble. The judge will ask them to prove it, though.
Refusing to break backward compatibility is how you end up with some of the uncomfortable anachronisms that can be found in PHP and MySQL and other things. A language that did backward compat arguably well is Java but it had to be extremely conservative, a property that has made it popular to replace wholesale with languages that are nothing like Java.

If it helps, you can convince yourself that Py3 is a different language that just happens to be very similar to Py2, and that Py2 needs new maintainers. This happens all the time.
If you are worried about epsilons and deltas being too hard, then you can write your calculus text to not be rigorous rather than trying to make it rigorous with non-standard analysis. I think giving up on some of the formalism while still sketching the ideas of proofs is the way to go from a pedagogical point of view.

>I'm not trying to disagree with your point! I just wanted to let you, and people reading your comment know that it wasn't accurate (as was described in the headline of the post and the article) in this case.

Then you did it incorrectly, because you worded it as:

>>>Except...the University in this case hasn't said ...

That is, my point is wrong, because this one case isn't actually happen. But my comment doesn't depend on this incident having actually happened! (It simply points out that this would be the natural outgrowth of the incentives, and that the hive mind would be inconsistent to object.)

If you were actually trying to do what you claimed, the appropriate way is to indicate it's a nitpick or that it doesn't affect the general point, or that you're just saying that to avoid a misconception that someone might get from the article (and not my comment) -- not to write it as a point of refutation, as you did.
The fact that categories are often fuzzy does not make them useless as a general heuristic for finding people who are more likely to share similar experiences with each other.

Almost every kind of categorization system shares the problems you talk about: people can call themselves "programmers" for a variety of different reasons, even though they're working in wildly different environments and might be totally unsuited for each other's jobs. People self-identify with political parties, even though there are no strict rules about what a "Democrat" or "Republican" are, to the point where beliefs of members of those parties might overlap with each other or even be the opposite of what the party normally espouses. We separate games/movies into genres, even though genres are often a complete mess that don't always map well to player preferences or experiences. We take a light spectrum and we break it up into distinct colors, even though the number of colors and lines between those colors are completely arbitrary and meaningless.

It's good to recognize that categories are fuzzy human inventions that are prone to abuse, and it's good to be cautious about putting a lot of weight on them in every situation. It's good not to assume that everyone in a category is identical. But abandoning categories entirely would make it much harder (even impossible) to go through normal day-to-day life.

So it is similarly useful to be able to think about categories like "Black", "Gay", "Conservative", "Christian", "Rural", "Trans" -- even as we acknowledge that those categories are just human inventions and that they blur around the edges. Those categories are still be a useful heuristic for trying to find people who are more likely to share certain attributes or who have had certain life experiences.

Now I want to buy a $10 million NFT of a doodle of a bridge at a garage sale for 50 cents.

The questions are:

How were the the "dumb money" NFT buyers ever going to liquidate their "investments" on the other side?

Did they ever intend to cash-out or just show-off how much money they can burn?

Or is it 95% blackmarket money (i.e., drugs, sex slavery, worker slavery) that had nowhere to go except buried in the ground or in the walls of houses?
What's a jurisdiction is a difficult and abstract topic, albeit an important one. I'm not a legal mind, so I'll leave that be. I am happy though that as a EU citizen my privacy is protected, to an extent, not only from actors based in EU, but outside it as well. Whatever legal framework that requires, I think that's a desirable and fair arrangement.

Poor 8 year old me really thought that Brendan Shanahan rookie card would mean something someday.
As a parent who has all three children fully home schooled now I can confidently say it is just the better way to educate children. The article slightly alludes to this, but homeschooling today is not the kids sitting at home independently going through workbooks, with limited interaction. The big revelation to me when we started this journey was that homeschooling can be done in groups, not on a day by day basis, but by aligning curriculum with other families and working independently you get this amazing interaction where the kids can relate to others doing the same work, they can have meetup's and group sessions on some regular basis, and they can still have a generally fully customized experience to meet the child learning exactly where they are.

The most poignant example of the overwhelming benefit of homeschooling was when we found out that our son was really struggling with math. He was able to answer most problems, but was consistently getting basic things wrong. He never actually internalized the math he had learned and now in 5th grade he was struggling with not knowing things like math facts or order of operations, or anything of how to deal with fractions. In a traditional school he would likely be tracked into remedial math, and would spend the rest of his school time there. However by just spending more time on math each day he was able to quickly address his issues and start better understanding his new coursework.

Same thing with reading for my daughter, she was a prolific reader, and quickly advanced to books she saw her older brother reading, but when we had her do school work she couldn't complete basic comprehension work for the age level books we were assigning. Well it turns out it wasn't that she didn't comprehend them, it was that she never learned how to communicate details, we spent six months having her read and explain very simple books, and quickly she was back up to speed and excelling in both reading and comprehension tasks.

We wouldn't have been able to do either of these without dedicated and time consuming intervention. The exact kind of intervention you would never get in even the most dedicated public schools. The only place you can get that kind of prolonged dedicated attention is with parents at home. Add into this that we have been able to _vastly_ expand the scope and sequence of what our kids are learning because we can just firehose them as much new material as they can take and you quickly see that a child who is excited about learning, who is able to explore and discover, and isn't bound to an artificial school day, or school year, or school curriculum will learn so much more then their traditionally schooled counterparts.

After this last year we are 100% sold on never sending our kids back to traditional school, it would be unloving and would be doing them a disservice. We decided that if it came down to it, we would rather move away from the extremely high cost of living world we live in today so we could be a one income household and give our kids the attention they deserve rather then let someone else try and raise them for us.
Interesting that your comment implies that the blog post in question wasn't "actually racist".

To me that speaks volumes.
Compared to Latin America as a whole? Yup, pretty clearly so. They're on a path to becoming more racially progressive than much of the U.S.
Right. Well it wasn't positive for my kids! And I'm not biased. My son and daughter are just as imperfect as they'd have been if we'd put them through school.

We did however save them from needlessly experiencing the problems they were already having.

So it's subjective. But isn't everything?
Why would a "right-wing" ideology's outrage be one a bigger level than a left-wing outrage?

You are making a false equivalence. Fox publishes outright nonsense like "Texas has 0 deaths from Covid now, showing mask mandates are unnecessary" (asterisk: for one fluke day in the metrics, so we're not technically lying, even though we know members of Congress will cite while paraphrasing into huge lies).
The liminal nature of the phenomenon is the calling card of a higher intelligence, seeking to fulfill/manifest it's understanding of metaphysical principles.

The primary metaphysical principle which, in my understanding, is seeking to be respected by these intelligences is this: Free will, even on the level of deciding what is allowed to be considered as real. A UFO that "proves its existence" to you has made concrete decisions about how it wants to alter your worldview. I believe that is a no-no.

The evidence that you will find in favor of UFOs, matches precisely or semi-precisely what the deeper nature of your belief system and mind want to believe about them. The Twining Memo alone, if meditated on and considered for its implications, proves beyond a doubt the reality of the phenomenon. I could rattle off a list of a half-dozen books that go into the topic in great detail. The amount of deathbed confessions and former insider testimony will astonish anyone, truly. The freedom to disbelieve in these things is protected. But even the Pentagon just came out saying that "UAPs" harass them regularly (with the implication known to those of us who research the matter, that this has happened ongoingly now for 70 years).

Basically just choose to open yourself to the possibility and I think you will find the evidence.

Hi there, I'm a member of the team at Google responsible for this dataset.

I don't see an artfact at exactly those coordinates, but is this nearby location what you are referring to:

tinyurl.com/4rpas73s

That appears to be a knife mark. This dataset was assembled from over 5000 tissue sections each cut at a thickness of just 30 nanometers using a device called an ultramicrotome. Tiny imperfections can develop in the diamond knife used by the ultramicrotome, which unfortunately can result in artifacts like that. Fortunately such artifacts are unlikely to affect the same location on multiple consecutive sections, and our segmentation algorithms are robust enough to segment through those locations.

By the way, one cool thing about the viewer, neuroglancer, is that you can just copy the URL to link directly to any particular view.
The audit is being funded by by a private party conservative news network. What results do you think they're going to find?
I don't know Antonio García Martínez's ethnicity, but he looks and sounds very much like a straight white male, so I would not consider that a counterexample. Also, certainly there are no absolute laws of who is always targeted and who is never, just clear trends.

However, it is true that to some small degree I am oversimplifying something quite complex, partially because the cited example was James D'Amore. Other examples you might cite include Dave Rubin or Ric Grennell. Certainly gay white men and straight white women (specifically if they are Republican) are targeted. What happened at Disney with the treatment of Gina Carano vs. Krystina Arielle is evidence enough of that.
If the positioning is precision enough, this could be have great applications in many industries.

Imagine having to tap into the work history of a machine and add latest repair works and notes for others.
One way to show evidence of audit tampering is to watch the live feed and report on any suspicious behaviour:

Because, as I understand it, the idea of an NFT is to demonstrate some sort of "ownership" of a work of art. The issue I have is that they don't do that. An ownership document that can legally be duplicated and distributed ad-infinitum by anybody at zero cost is not an effective ownership document. Even for the novel and legally meaningless version of "ownership" conferred by NFTs.

If Damien Hirst sells 1000 sharks, the buyers get the physical sharks themselves, I guess along with some falsifiable and legally meaningful documentation. They really do own the sharks, physically and legally.

A judge said this audit follows all the laws. It's been litigated.

Please do your own research -- not listen to partisan talking points.

Here's a public discussion around some of the findings, the Arizona Senate is very clear about what is going on and seems extremely reasonable:

https://invintus-client-media.s3.amazonaws.com/6361162879/90...

This audit appears solid to me, I've watched all the court cases and read all the public documents. U.S. Election Assistance Commission (EAC) provided input regarding the audit (https://www.eac.gov/). The president of the Arizona Senate explains this.

This is amazing gaslighting by the media.

This audit has three people counting, photos of the ballots (to later check), checking folds, etc. This is a very well controlled and good audit. Not perfect, but far better than what we had in the past. There are observers from the secretary of states office, democrats, republicans, independents counting, multiple sign offs and everything is recorded so they can go back.

You can view the audit live on some of the cameras: https://azaudit.org/
My first reaction is “good, there are too many of us anyway.”
We’re in for some stress, though, if the Social Security system is predicated on a growing number of workers and retirees not living too much longer past retirement.

I have a child, and one is enough. We’re not a threatened species in terms of numbers, and I argue we’re less threatened if we scale back “progress” and then redefine it towards supporting a long, healthy, unbroken story until survival is out of our control. Much of this comes down to what we value.

Stealth is just as useful for defending and for attacking, and arguably I'd say even more useful for defence because the attacker will never be able to field counter-stealth radars. Stealth when combined with counter-stealth radar on your home turf gives you a huge advantage as you now know a lot more about your enemy than your enemy knows about you. Non stealth aircraft plus counter stealth radar is a lot less of an advantage.

US VHF radar is likely not ahead at all. The US has never fielded a VHF radar, while the USSR and by extension Russia and China have done so since the 70s. The US has UHF radar and is definitely ahead in conventional radar though.

The interests of China and Russia do involve attacking sophisticated opponents such as Japan or Western Europe in order to destroy American infrastructure in a defensive war. It's just that instead of using stealth fighters to do so, they intend on using overwhelming numbers of missiles including hypersonic cruise missiles, of which the US doesn't even have a prototype yet.

These decisions weren't made in the last few years. They are tactical decisions as a matter of doctrine that were made in the late Soviet era. It's not a coincidence that these countries are ahead in counter stealth and ahead in hypersonics but behind in other things, they invested in what was most useful to fit their doctrine.

Is there some zero day that's getting out and causing a lot of these recent ransomware attacks? Has anyone been able to do some root cause analysis on the exact exploits that oil pipeline, meat processing, etc. plants have faced with their ransomware attacks?

On one hand it seems a bit expected to see an increase in attacks after big, public ones... but on the other hand how are these networks and computers actually getting compromised with what appears to be such speed and ease?

edit: I also wonder if defenses need to get more proactive about detecting these attacks. Why can't block devices have a mode where they immediately shut down into a fail safe if they see a huge amount of sustained block overwrites (like attempting to overwrite 50% of data within a short time span)? Or maybe bake copy on write filesystems into the hardware such that no matter what happens on the host side a perfect history of previous blocks is kept intact to be restored through some manual/external intervention.
My approach has been to resell something that already exists, with a healthy margin.
