The word tensor has become more ambiguous during the time.

Before 1900, the use of the word tensor was consistent with its etymology, because it was used only for symmetric matrices, which correspond to affine transformations that stretch or compress a body in certain directions.

The square matrix that corresponds to a general affine transformation can be decomposed into the product of a tensor (a symmetric matrix which stretches) and a versor (a rotation matrix, which is antisymmetric and which rotates).

When Ricci-Curbastro and Levi-Civitta have published the first theory of what now are called tensors, they did not define any new word for the concept of a multidimensional array with certain rules of transformation when the coordinate system is changed, which is now called tensor.

When Einstein has published the Theory of General Relativity during WWI in which he used what is now called tensor theory, for an unknown reason and without any explanation for this choice he has begun to use the word "tensor" with the current meaning, in contrast with all previous physics publications.

Because Einstein has become extremely popular immediately after WWI, his usage of the word "tensor" has spread everywhere, including in mathematics (and including in the American translations of the works of Ricci and Levi-Civita, where the word tensor has been introduced everywhere, despite the fact that it did not exist in the original).

Nevertheless, for many years the word "tensor" could not be used for arbitrary multi-dimensional arrays, but only for those which observe the tensor transformation rules with respect to coordinate changes.

The use of the word "tensor" as a synonym for the word "array", like in ML/AI, is a recent phenomenon.

Previously, e.g. in all early computer literature, the word "array" (or "table" in COBOL literature) was used to cover all cases, from scalars, vectors and matrices to arrays with an arbitrary number of dimensions, so no new words are necessary.
Panzer Dragoon Orta did, along with (I believe emulated) copy of the original Panzer Dragoon embedded inside, but not Saga.
I don't have to distinguish anything, I just have to the humility to listen to what the experts say, rather than a bunch of webdevs.

EDIT: Also, i'm not a biologist, but I see the same phenomenon in finance where a bunch of low pay webdevs nobodies refuse to make an effort to understand why Excel is popular, push their half backed solutions, and then are confused that nobody uses them, and frustrated when showed for the 10th time the feature set, that they don't really have the attention to detail to implement. Then i come on HN and realize "oh so _this_ is where these people come from".
The user manual for these things was quite amazing and instructional.

The article devolves from fact to fiction/guesswork rather quickly.
Haha, you think scientists have control over what software their employer buys for them to work on.

There are probably wonderful places where that is the case, and probably several of those places use something like libreoffice which doesn't do the idiotic data conversions excel does, but they are definitely not the norm.

I'd say

- open source works because there is a large amount of work that's done by people other than the main authors, or people outside the project. e.g. See all the documentation that's done around Linux or git.

If you try to sell a small piece of software, I believe in most cases that the cost of developing will be dwarfed by the cost of support, documentation, and marketing.

- Giving away almost everything is standard for both open source and for for-profit.

That seems to be inherent in the structure of the economy at this point. If you don't give away a lot, you don't really compete. e.g. see the social media companies that wanted to charge for usage

sqlite seems to have sustainably paid employees, but it gives away 99.9% of the work. Similarly, free tiers often give away 99% of the features of commercial products, with some artificial caps.

- Likewise, going into debt seems to be standard practice. It's hard to be competitive against organizations taking on huge amounts of debt.

You might not think it's the same at a small scale, but I do believe there are say lots of crypto companies hiring technical staff that "distort" the market of who can help you, e.g. compiler engineers

- SaaS seems to work more at the application level. I always thought it would be nice to sell low level services like data feeds, but in practice that seems rare. (I guess Bloomberg terminal is kinda like selling data behind an expensive piece of hardware. Similar to Apple, if you have the resources to achieve this vertical integration, then you can have a "moat")

---

It would be nice if there were other models for sure. But I don't think the problem is necessarily software, as much as "small".

I think the economy is structured in a way so that the competitive actors tend to be groups of people aligned in some corporate structure (which does kinda suck). As in the beginning of the post, it says "your competition is highly paid teams are profitable companies".

Even a big company like Hashicorp has problems competing against those companies, and apparently Redis. And also nytimes, Universal music, and every other media company. The economy is not a friendly place.

Certainly there are one person businesses like tarsnap and pinboard and so forth, but I also think marketing and support is a big problem in those cases.
FWIW I have been writing SIMD since 20+ years and worked on JPEG XL, which also contains a good bit of vector code.

A fantastic interactive introduction to Kalman filters can be found on the following repo:

It explains them from first principles and provides the intuitive rationale for them but doesn't shy away from the math when it feels the student should be ready for it.
In my experience PMs are not rewarded for good product, but rather a mix of shortsighted metrics and whatever their VP/senior person has on their personal agenda. At big companies, employees are often not even using their own products. The corporate ladder is all that matters.

Obviously that’s not unique to the PM role, but seemingly more prevalent. I think it’s an effect of the rootless roaming you get when you spread people thin over large areas, and don’t have clear ownership and responsibility – which I think is a prerequisite for (the good kind of) pride.

But overall, yes, it’s definitely a structural issue with the organization at large. Clearly, when it’s gotten as bad as in this case.

I assume the complexity of the platform contributed to games being rarely ported off of it. In fact, the only games I know to exist on it and other platforms, are ports to the Saturn, never the other way around, although maybe someone can correct me.

From what I understand, emulating the platform is still tricky to this day, although there have been some significant advances in the last 10 years.

These are different letters for people who speak the language and treating them the same in some usage seems weird.

At the same time, sometimes words containing those letters might show up in context where the user is not familiar with that language. Such users might not know how to enter those letters. They might not even have the capability to type those letters with their installed keyboard layouts. If they are searching for content that contains such letters (e.g. a first name), normalizing them to the visually-closest ASCII is a sensible choice, even if it makes no sense to the speakers of the language.

It's important to understand a situation from different perspectives.

It's not about coming up with a single correct interpretation that makes logical sense. It about making a system work in least-surprising ways to all classes of users.

I think it's unfair to dismiss Affinity's products as Adobe clones. They do their own thing within the conventions expected of modern graphic design apps.
They use licenses imtended for installing multiple servers and sell them as single licenses. the problem is that the usually sell the keys directly and don't convert them to single licenses. If they would it would be more legal. Just having an key doesn't mean you have an valid license, this makes it complicated
You can have smaller container ships. Or have the port outside the bridge. Or indeed replace the bridge with a tunnel, or a better bridge.

Amsterdam has no bridges at all crossing the IJ on the west side (where sea-going ships come from) and only a single bridge on the east side (though there's often talk of adding another). Everything is tunnels.

Rotterdam has bridges (including the famous Erasmusbrug), but only east of the port area. To the west, everything is tunnels. And the largest ships don't even come close to the city center, but dock at the Maasvlakte out at sea.

For both cities, ports have constantly moved closer to the sea.

The Mathews Bridge in Jacksonville was clipped by a container ship a few years back and did not collapse. Despite being almost 75 years old, they fixed it up and it opened back up after a year or two. The difference is that the boat did not hit a pylon.

Consider claim:

> The feasible region {x | f(x) = 0} is nonconvex no matter whether f is convex.

For some positive integer n and for the set of real numbers R, consider closed (in the usual topology for R^n), convex set A a subset of R^n. Define function f: R^n --> R so that f(x) = 0 for all x in A, f(x) > 0 for all x not in A, and for all x in R^n f infinitely differentiable at x. It is a theorem that such an f exists.

Then { x | f(x) = 0 } = A and is both closed and convex in contradiction to the claim.
I agree with the above, but have you looked public sector? (e:g gov't , academia) low-key, sane culture can be found there. Simply because the org is not constantly chasing the next quarter's profit. Its not utopia, but in my experience (mostly private sector but a fair chunk of public sector) , public sector is so much better, less stress, and ironically, more productive because you can make long-term decisions, fix broken processes etc for the benefit of everyone. You won't get paid as much headline salary.. but you might get a better pension so needn't put as much aside, also, burning out can cause lost earnings anyway, so unless you're some kinda rock star with millionaire potential, it probably comes out in the wash .

Anything's possible, but a ship losing steering control is not that uncommon.

This just happened at a particularly bad time and place.
I love Affinity Designer as a tool and his pay once license, I'm pretty sure that if you already purchased current version (V2), you will be fine, but I'm afraid they will go the subscription route soon like Adobe and Canva.

Is suspicious that Affinity marketing was always highlighting the pay once license model and against subscription, and in the official announcement there is no mention of that.

A lesson is that with the good ol Inkscape that type of thing that endangered the tool it doesn't happen.

If you read the court case findings the IA was not doing CDL as they claim. They had lost control of whether or not the digital copies were backed by physical copies at all. They were also pushing people to buy used copies from a site part owned by the person who runs IA.

I think CDL can work and win legally. Unfortunately, IA's blatant disregard for copyright has poisoned the well for likely a long time to come.
>go on a PM-centric feature frenzy

Do developers have any agency whatsoever, or are they at the mercy of doing whatever their managers suggest (while always knowing the "right" answer, of course)? Does our industry attract people who avoid accountability?

Fraud? It's the executive's fault. Business struggling? It's the MBA's fault. Bad product? It's the PM's fault. Must be nice!
> punish the grumpy ones in favor of the people-pleasers, that this crap happens

This isn’t exclusive to technology, but I see this all the time at my large organization. As a grump, I have to pick which shitstorm to care about and spend my time chipping away at, which ends up being really draining.

To help with this, we began focusing a team of great folks with shared values, leaning in on modern operations/SRE best practices.

We started to have some real success with SDLC for our operations workflows.

That’s when management changed our teams direction. Good times.

The subhead is "The antisemitism of campus leftism may be incidental. The barbarism* is the point." and somehow it actually descends from there, ending almost four thousand words later with: "as long as the academy is committed to forming young people who are not interested in being decent citizens—indeed, who are trained to be exactly the opposite—it should be treated as the locus of the civilizational crisis it is."

Ditto, Rush!

A growing number of doctors are advocating what might seem like an unusual position: That low-grade prostate cancers that grow very slowly or not at all shouldn’t be called cancer or carcinoma.

If Adobe would have a little bit of brain left, they would offer a cheaper subscription now. Essentially covering Photoshop, Illustrator and InDesign.

For a Firefighter Struggling with Trauma, Ketamine Therapy Offers Hope
I leave it to others to figure out what the physical health effects are. But I can tell you that here in Melbourne, the mental health effects are still acute. Individually, nobody I know has ever recovered, even if they think they have, and collectively, the whole city has a completely different feeling, a pall hangs over it, and there's a feeling like it has some pent up anxiety just below the surface.

I think millenials and zoomers will need to be gone before its effects aren't felt at some noticeable level.

This is all made much worse by the fact that nobody feels like they can talk about what happened. There was no catharthis or discussion, everybody was just expected to return to living like they ised to. And nobody dares open their mouth, because whatever side of the fence they were on when it came to the lockdown, they don't want to deal with the response that anything short of unquestioning praise for the measures will garner them.

It's sad. The city is a shadow of its former self, as are most of the people.

Nano is only fast because it is centralized. Just like all other "fast" token systems are centralized.

And regarding instant, feeless transactions - do you believe that electrons carrying current bank transfer messages are slower or more expensive than the ones carrying tokens (physicists, please forgive me)?
