My point is I think simpler than what you're talking about, so let's replace "symmetric" with "diagonal." Suppose I have a structurally diagonal matrix, represented by a type `Diagonal` that can only represent diagonal matrices, and then a non-structurally diagonal matrix, represented by a normal dense matrix filled with zeros except on the diagonal.

I pass this as input to some function that uses more than just the diagonal and compute the gradient (here a matrix). In general, for the dense matrix, the resulting gradient will not be diagonal. Why should it be? If your function doesn't care if the matrix is diagonal, neither does the AD.

But what about for `Diagonal`? Well, the AD could handle this different ways. First, it could interpret all matrices as embedded in the dense, unconstrained matrices, in which case it would return a dense non-diagonal matrix. Or it could ignore that `Diagonal` represents a matrix entirely and instead return some nested structure that contains gradients of its stored fields, here the gradient of a stored diagonal vector. Similarly, it could represent this nested structure as just another `Diagonal`.

There are various reasons why an AD might do any one of these; neither is right or wrong. But note that the only case that gives you the same answer as the dense one is the one that promotes to a dense input, which is basically discarding all structure to begin with.

Most ADs don't ever have to work with matrix polymorphism, so their user bases don't need to think about this, but Julia has _many_ polymorphic matrix types, so Julia ADs have to take this seriously, and if new users naively pass a polymorphic matrix type as input to some `gradient` function, they might be perplexed at what they get back and think the AD engine has a bug. See the ChainRules talk at EuroAD 2021 for more details: https://youtu.be/B3bC49OmTdk?t=761

It is a weird situation because it's hard to decide where to draw the line. Even right now the exceptions are weird and semi-arbitrary. Everyone paying 30% doesn't work, but neither does no one paying 30%, since every app would just switch to subscription model to avoid paying Apple.

It's also tricky to change the status quo since at this point a huge chunk of their revenue is the AppStore, and any serious change in the 30% will impact that greatly, upsetting investors. Once you take the step forward, it's very hard to take a step back.
Of the answers posted here I am curious if any of them are suitable for mobile (iOS/Android) or desktop (Mac/Windows) apps, or if they are all web-oriented?
What's missing is that companies don't pay the 30% -- it's the end-users that do. Every user of iOS pays 30% of every app and IAP to Apple. The other company never even sees this money.
Just because something gets does doesn't mean it's sensible. That's like arguing coal is the future because China and India have brought online thousands of TWh since 2014. You did not actually address any of the points mentioned in the article explaining why Li-ion is not the go to solution for grid scale storage. Flow batteries have only become relatively cheaper since then btw.

I have a decidedly love/hate relationship with LinkedIn.

Almost all of my work for the past decade has come via way of LinkedIn or referrals, and usually the referrals from older colleagues are because they could find me on LinkedIn. You don't _need_ a LinkedIn profile, and you're not obligated to provide it on a job application. Having a LinkedIn profile is a useful automated marketing tool, and a more extensive, cultivated version of your resume/C.V.

I have also found, that as an engineer/developer, that I don't use LinkedIn the way the majority of engineers/developers use LinkedIn. LinkedIn is a marketing tool and should be used as such.

LinkedIn is also full of low-quality recruiter spam and people not even glancing at your profile before reaching out with a 6 month/$20 an hour contract Java position on the other side of the country.

This is just textbook rent-seeking.

Like the classic example is someone setting up a barrier on the river and charging boats that want to pass through. There's no value being added by the person blocking the river.

Just the same, when Apple says "Let's charge for this", what value are they adding for doing so? They make money off the current system. They just want to make more money while providing zero additional value to consumers or to app makers.

What's funny is if you're completely broke and have kids, there are tons of government benefits designed to keep you afloat. But if you have a little too much money to qualify for those benefits, you'll feel like you'll never have money for kids.
This article is obviously propaganda meant to counter the headlines about the Worker’s Party leading in the polls.

The working people of Brazil have suffered tremendously under Bolsanaro’s neoliberal government and Lula (Worker’s Party candidate who Bolsanaro imprisoned for 2 years on bogus charges) has a big lead. After the recent socialist victories in Chile and Bolivia (following the U.S.-assisted coup), western states will do everything they can to prevent the Worker’s Party from retaking power in Brazil. Expect more of this and other hi-jinx as the Fall election nears. It’s going to be a messy one.

Both are kind of true. On individual items the margins are pretty large. But the operational costs are large and so on net the profit margin is low.

Unlike a store, Apple wants the margin without doing any of the work.
We can choose to have a legal system where this is OK. Or we can chose to have a legal system which busts anti competitive practices like this. Both are possible and I know which one I would vote for.
Python for sure.

The stdlib in python is full featured and you can do a lot with it and the syntax is easy.

Rust would be a terrible choice, the last thing a child wants to do slam their head against the wall with life times.

Whatever you choose make sure the feedback loop is tight. Children will want to "build" something, not fight with error messages.
Plausible.io is my favorite. Cheap, self-hostable. Really stellar support.
I am quite baffled by the vibe of the comment section here.

The author explains why they do not feel like writing a technical blog, and those are (1) they have nothing interesting/new to say, (2) they are not a good programmer, and (3) it is not a good CV building.

I don't know about (1) and (2), but I respect the author's self-assessment, and I agree with (3), overall a technical blog is not a good CV builder, although there could be a confounder at play here, in the sense that who could write a popular tech blog is someone who has enough skills not be worried about having any other items to be added to the CV, like writing a blog.

But the general vibe is that somewhat the author is wrong in their self-assessment.
They should write for themselves and then publish or not publish—— similar to the love letter sent to the boy/girlfriend who dumped you that you should not send, but you should burn——or write for helping someone that in 3 years are gonna find themselves with the same problem, or that writing it down helps organize the scattered thoughts in one's mind (like people who are not writing those thoughts down are like pilgrims lost in the darkest night with no oil for their lamp) or they need a boost of confidence, because they surely have something to share.
And many are forgetting the opportunity cost: it takes time to write, and energy, and not getting any view is frustrating and maybe not a game one wants to play.

Like someone shared their thoughts on why they should not upload their salsa dancing on YT (they are not very good salsa dancers, they have nothing to teach, and nobody cares they salsa dance at Farmers Insurance where they work) and people started saying that no, you should upload to YT because maybe you are better than you think you are (why?), you may have some unique way of explaining the third step or whatever (really), it is the best way to find a romantic partner (and?) and who tells you that your skip-level manager at Farmers has a daughter who dances competitively and you may find through a common passion and through the grapevine of family a better connection with "leaders", which could give you an increase of 1k per year (before taxes)?

I, after having read the blog post and coming from a perspective of respect of the author, agree they should not write a technical blog. I don't see any reason for now, tomorrow who knows.

fwiw, the template text in this case are comments so that gets stripped
To be precise, the previous comment was about whether he achieved “immortality”, not a personal sense of satisfaction in his contributions.

It is gratifying to know he achieved the deep peace of believing he had been “successful”, and by that I assume you mean he achieved the important personal objectives he had set for himself.

In the formal sense, no one’s personal contributions ever confer immortality (heat death of the universe) and, paradoxically (as is true for all great truths), everyone’s contributions always confer immortality (albeit anonymously). Depending on how you looks at it. The way I look at it, it’s a silly metric the monkey mind makes up to distract the actual immortal soul from experiencing a full life.

This is hard.

Early in your career, I'd say stay where your at. Most of us will never get to FAANG and you have no idea if this startup will make it.

Plus if they're hiring you as the lead engineer for the company that's a major red flag.

You bring in experienced people before junior devs.

I wouldn't do it, the vast majority of startups fail or sell for less than they took in investment.

Don't assume you'll get rich

Reverse it, say your at a startup and a FAANG offered you double the pay. What would you do ?

There’s some nuance to be had, to be sure.

But I think we should be able to agree that demanding 30% of nearly everything and completely banning any sort of alternatives is extremely overbearing and ends up taking a lot of money out of the pockets of people struggling to get by.

So far they are great. Snug fit but not horribly uncomfortable like some N95s I have worn. They also have a plastic do-dad that so far has kept the straps from breaking off (all so common to N95s). Short use period of a few days but no issue with the metal nose piece either.

> Someone give me a good argument for why Apple deserves a THIRD of revenue generated from apps on their platform?

You are using their intellectual property? As in the App Store? Thus, as long as you are using that to distribute your app, they are entitled to collect the commission from where-ever they want and it doesn't matter if it is IAP, Web, etc.

From [0] of page 66

> Under all models, Apple would be entitled to a commission or licensing fee, even if IAP was optional.

From [0] of page 112 (b)

> The Court agrees with the general proposition that Apple is entitled to be paid for its intellectual property. The inquiry though does not end with the bald conclusion. Apple provides evidence that it invests enormous sums into
developing new tools and features for iOS.

Yes it's more, getting such a magical piece of artwork created, with everything that goes into it. To me, the "story" of the Pixar movie is perhaps the least interesting part (except for something like Wall-E which is pretty novel)... stories like "what if an animal got separated from his dad and got lost?" is not a very novel idea but Pixar made it to 100% perfection.
At this point, I think the way this will all end up (and would be fair) is for Apple’s payment system to remain, but you can choose to use another one. Apple’s take will probably fall in line (otherwise no one would use it).

I also kind of like the idea that something like that happens, except games all caps must use Apple‘s system and pay the 30%. That’s not as fair, but might be workable.

If I had my way over all of this? Do you know what I really want?

No consumable in-app purchases. Period. Outlawed.

One of my favorite things about the early iPhone was the incredible games that you could get. Now there’s almost none of them, the developers of practically abandoned the platform. The only ways to make money are ads and consumable in app purchases which are just complete scams. Like $1000 buckets of Smurfberries.

That’ll never happen. But I wish it would, because it would bring back the great games.
I've got original iPad and first iPad Air once the first owner got newer devices - both are mainly used as ebook readers (with third-party apps).
iOS has allowed side loading for half a decade now. Companies that find $100 prohibitive have a free path that’s nearly identical to Android side loading.
I believe that:

1. The closest known animal viruses to human SARS-1 were found in civet cats in 2003, within about a year of the first discovery of the virus in humans.

2. No animal viruses closer to SARS-1 have since been discovered. Dr. Shi discovered various viruses in bats that we believe are ancestral to SARS-1, including WIV-1 in 2013. This is significant because we believe SARS-1 evolved primarily in bats, but those viruses have lower genetic identity with SARS-1 than does the virus found in the civets.

If you disagree, please link a paper.

Based on the above, I don't understand why you'd think 2013 is the important date. Within about a year of the emergence of both of the previous two novel coronaviruses in humans (SARS-1 and MERS), a near-identical virus was discovered in animals (civets and camels). This is suggestive but not conclusive evidence that those animals first infected humans, and strong evidence that those viruses existed in nature--somewhere, even if not exclusively in those animals--before they emerged in humans.

For SARS-CoV-2, no such evidence has yet been found. This doesn't prove that SARS-CoV-2 is of unnatural origin, and I assume you'll mention the uncertainty in Ebola's zoonotic hosts shortly; but I don't see how anyone could treat that as irrelevant, except out of willful blindness.
what happened to the pressure US senate was supposed to put on those platforms to stop behaving like the mafia ?

Apple lowered its fees to 15% but that can't be the end of the story, right ?
Yeah I think its fair that Apple charges whatever they want for whatever service they provide. They can charge for the App Store, they can charge for the dev tools and SDK.

But that everything they charge money for, they _must_ allow alternatives to exist. If they want to charge a large fee for getting on the App Store, they must allow alternative app stores. The problem is not that they charge money, but that they use their massive user lock in to force people to pay for these services to exist in the market.
There is no "punk generation" -- there were conformists in every generation, and most mass movements, whether "protest" or reactionary build on the fact that humans are tribal.
Sideloading is not allowed per Apple rules and requires jailbreaking which comes with a list of caveats. So technically yes as a user I can side load but as a company providing apps it's not a realistic method of app delivery for the vast majority of use cases.
So neat! Where are you based? Boston, I assume?

> economy is 50% real estate,

That mirrors what Canadians have told me. There's little interest in innovation and building tech when the simplest way to make money is simply housing.

The CSeries comes to mind, it was almost ready and had orders for years, then the Trump admin slapped tariffs on it and Trudeau did basically nothing. All it needed was a little capital injection while waiting for the courts to declare the tariffs illegal and remove them. Instead, Airbus bought it for virtually nothing.

As someone in tech, it's scary to see how little support such an innovative plane got from the government. This would never happen here with Boeing (just look at the 737 MAX) or in Europe with Airbus. And the A220 (the rebranded name) is making a fortune for European investors right now.

> immigration is 95% of population growth and has resulted in a very exploitative and corrupt system that lures in young people to be poorly-paid expendable labour under the guise of Canadian Permanent Resident

The point of immigration is to fill a shortage. That's why here there are rules regarding salary requirements for immigration purposes. If a job isn't paying a lot, it's because it's not in demand; why then bring-in more people to an already saturated market? What’s the logic here?
Galaxies like this truly challenge MOND theories of modified gravity.

If there is no such thing as dark matter, why doesn't this galaxy behave as the others do? It has the same amount of normal matter as it's neighbours, yet acts totally differently. Dark Matter as a theory has an answer: this galaxy has none. MOND has a much harder time explaining it.
The system you're describing is a system in which random policemen can arbitrarily destroy the life and legacy of whoever they want. Such a system does already exist in many countries. It doesn't depend on people actually hosting decentralized communications facilities at all; police officers can do the same to anyone who refused them free accommodations at their hotel, or declined their offer of partnership in their nightclub venture. It's irrelevant whether there's any forbidden information actually being communicated, striped or otherwise.

In other places, there does exist a "rule of law" that limits such abuses to a significant degree.
I see where you're coming from. From where you sit Jupyter is a language agnostic tool and so in. But the fact that there's dozens of solutions in this space is surely a problem?

I'd have thought there would be some things you could strongly encourage:

1. Come up with some standard format where the code and the data live in separate files.

2. Come up with some standard format where you can take load a regular .py script as a cell based notebook using metadata comments (and save it again).

If these came out of the box it would solve most of the issues.
I assume that you are thinking of a pure monopoly - a single supplier.

When we are talking about monopolies in this context, we mean monopoly power, monopsony etc. For example, when a firm’s ability to charge a price higher than its marginal cost with very little change in demand of their product, it has monopoly power.

When deciding if a company is a monopoly, the first thing to do is 'market definition' - defining the relevant market. Is the whole mobile phone market? Can companies realistically compete if they produce only Android apps? It is in any way practical to assume that people carry two phones? Obliviously not.
Penalize? So it’s ok for a group of people to enter a contract to form a corporation (“penalizing” non-signatories by preventing them from benefiting from the profits of the corporation)… but it’s not ok for a group of people to enter a contract to collectively bargain with a corporation (“penalizing” non-signatories by preventing them from benefiting from the contract).

This is absurd.

You’re saying a corporation cannot enter into a contract to be the exclusive supplier of a widget to another corporation?
