The phenomenon you are talking about is essentially that of a homomorphism, or homomorphic structures. That is, structures that appear superficially different but share an underlying common structure.

The concept of a 'functor' was invented to describe a higher order 'homomorphism of homomorphisms'. An example most people miss is the total derivative in multivariable calculus: the chain rule implies that the total derivative is a functor that maps the composition of differentiable functions on a manifold, to matrix multiplication (of matrices acting on the tangent space).

You might also be interested in various 'dual' concepts, like that between tangent spaces and cotangent spaces in differential geometry.

For algebra, I'd recommend Pinter's Book of Abstract Algebra.
Can you give a rough idea of what ideas the latter chapters get into?
I am so relieved, and happy, to see Tim Bray (of famed XML) tackle this problem with such wisdom and long term view.

Yes, Amazon is a problem, and no, it's by far not the only one.

I am quite not sure that breaking up big businesses like Amazon and Google will change things much, by the way. And I am not sure that unionizing Amazon would solve much, either.

To be honest, I am quite pessimistic about our ability, as a society / human specie, to really solve the inequality problem Tim is mentioning. Sorry I don't have better words to say.
Interesting breakdown:

1% eponymous class
9% professional elite
90% working class

That's actually more skewed than the society described in 1984[1]:

2% inner party
13% outer party
85% proletariat

Note that the 2% keeps the 13% toeing the party line (they don't have to amongst themselves, and proles are explicitly said to be free) to avoid any sort of Manor Farm pigs[2] getting funny ideas. IngSoc only had one party, but if one allows two outer parties, nominally opposed to each other, one may discover they each spontaneously self-police their own thought criminals.

[1] I've always thought of 1984 as being a very anglophone sort of dystopia, but now I believe Orwell was writing therapeutically, cathartically imagining a world in which the social constructs of his second-rate english boarding school applied to the whole of society.

You can ask for C, C++, PHP, Java horror stories. You can ask for AWS, GCP, Onprem, Digital Ocean horror stories too and get some. You can ask for developers, system admin, DBA horror stories, MySQL, Postgres or Oracle. Just because you get a story doesn't mean the topic in discussion shouldn't be used or isn't useful. Sometimes horror stories happen because of ignorance.

Here's a k8s horror story I heard. A company lost their entire cluster. Everything. Here's the flip side, they were able to rebuild their entire production from scratch and be back up in about 2 hours.
Hey All.

My name's Brandyn and I've been working on a new MVP to help remote teams stay connected (it's been a grind..)

I've been working with remote employees & contractors around the world and one of the problems I've found was the difficulty in trying to keep everyone in sync due to different time zones.

We really like being able to have daily standups and weekly team meetings but were never able to get everyone on them at the same time.

So we created Grapevine, an asynchronous meeting platform for remote teams.

I would be SUPER grateful for any feedback (good or bad) on the product. It's been a bootstrapped effort to help solve a problem we had, and I'm hoping it helps others as well.

Thanks HN!

> Did it displayed assets

It's an API. There are many tools built on top of it, many with UIs. I'm sure they display things in many different ways for people internally and externally. The system I was working was back-end. It used negative numbers for debits. And it was really important you didn't confuse credit and debit numbers.

> Was that accountant fine with assets as negative numbers?

I find it hard to believe they didn't understand that's what Using negative numbers for debits means. They would be pretty aware that assets are debit accounts.

> The did have $1tn in their balance sheet. No DB, no CR. Just $1tn.

Did they have a complex balance sheet (I.e. beyond that just a couple of lines summary) with no columns? How do they represent a balance if you couldn't tell which were credits and debits?
I skimmed through part of it and found this gem in a footnote:

Probably the greatest UX innovation in microwaves I've noticed is the "start now for 30 seconds and keep adding 30 seconds every time I press this" button.

Want 90 seconds? Press the button 3 times.

Want 5.5 minutes? Keep pressing the button until the display says you're there.

That way there's no confusion about what 120 means. For one thing, the difference between 20 seconds and 30 seconds is negligible, so might as well only work in half-minute increments in the first place.
There is no such thing as risk free investment.

We can also literally pay most people not to work. There's already a ton of proposals for essentially scrapping the bureaucracy and overhead of evaluating issues and just paying everyone. (With a similar total spend) A lot of conversation is stuck now with false dichotomy of: people need to work or they won't have money. Raise taxes on top percent, freeze a lot of army spending, freeze or cancel student debt, and give people money for rent and food. It's that simple, yet not popular.

They have similar metrics, that doesn't mean they're copies of each other. The underlying designs are most certainly different (eg. chiplet vs monolithic). The reason they have similar in those metrics is probably due to convergent design, ie. these combination of functional units provide the best performance to transistor ratio. You see this in nature too. eg. https://en.wikipedia.org/wiki/Convergent_evolution#Opposable..., which look similar at a high level, but are actually different in implementation.

Does not need to be this complicated. It is pretty simple. There is one human race and in that there is human caste system (HCS). Its (extremely fickle) purpose is to divide/group peoples and create a power stack. Those at the top control those at the bottom. Heck, its also just tribalism.

Generating SVG for the Prime Knots
That's true for most countries. For the USA those tax treaties for some reason didn't work like that and double taxation of corporate profits does occur.

https://hbr.org/2012/07/a-better-way-to-tax-us-businesses

Under its current system the United States taxes the worldwide income of its citizens, including corporations. Foreign income is taxed by the source country and then taxed again by the U.S. upon repatriation

Because there are credits against the double taxation, if US tax rates = the tax rate in that jurisdiction then it cancels out. But many places have different rates and then the double taxation kicks in again - they get taxed on their income once abroad, and again if they bring the money back to the USA, so they don't do it. Changing the rates is a band-aid: most countries don't do this kind of double taxation to begin with.
Yup! Only about 20% of flu deaths are confirmed by test. The rest are estimated by an algorithm (which the OP alluded to)

> "Renduchintala was one of several key hires from outside Intel, which had been famous in Silicon Valley for developing and promoting talent from within."

Which was, IMO, one of the reasons why I left Intel. I interned there and did a 2-year stint.

What I saw was a culture where almost everyone who was there began their career at Intel, or at least joined very early in their career. No one was really aware of what the rest of the industry did.

In a way, Intel used to be a FAANG, but became a victim of its success as a great place to work. The culture was so insular that they lost touch with the rest of the field.

DFW is notorious for this, in his non-fiction essays he goes on so many tangents within the main text already, often only to then go off on yet another tangent in an almost page-long footnote.

Funny thing is he sort of parodied himself by going all out in his 2005 piece "Host" [1] by going so far as to nest footnotes within each other. That piece is actually interesting to compare across different media, as the interactivity of the web version makes it somewhat elegant to look at or skip the footnotes at the reader's discretion, whereas in the print edition in "Consider the Lobster", they are put in boxes within the main text and connected by arrows.

It takes a great deal of concentration/"work" to read his stuff but when you're in the right frame of mind all the depths and semi-related thoughts can make it all the more interesting...

The article covers a lot of territory but I can say from experience that the limitations to current CGI techniques mean that automation is still a ways away.

I produced all the shots for a global diaper company that is on shelf today. The pack designs were a tough format: images needed to be extremely horizontal on one side, and vertical on the reverse. But you can't just ask the photographer to shoot wide and crop in, because the new HD Flexo printing is way more hi-res. The approach at the time was to take the baby imagery and 'paint in' the extra background in Photoshop, a very time-consuming process that had to be repeated for every single image for every single region, with wildly inconsistent results. We created a replica of the on-set nursery in CGI, all the way down to matching the lighting in the C4D studio.

Yes it made the process way more flexible, yes we could localize everything with a new render, and yes we could add props or change the decor. But every render required a human eye to match the camera angles/scale of the baby shots. The uncanny valley is real, even with all the little tricks you can do to make it seem more photorealistic.

I do like the idea of AI-generated baby faces - the casting process / ethnicity requirements / rights management challenges are real. And maybe it wouldn't be all that bad if everyone knew that the babies weren't human. But the cost to develop and manage that system require real experts, a huge expense for a company that only needs baby shoots every so often. I imagine a version of 'thisbabydoesntexist' and how that would even slot into the content production workflow - it feels impossible. It's much cheaper to outsource this stuff to production companies that are smart about how they capture all the different kinds of content.

There are definitely companies where CGI makes sense to develop in-house. IKEA's approach comes to mind since they have super modular and global approach to furniture. But most companies have such a big product turnover that photography is still cheaper. Don't even get me started on hard-to-render products that require serious expertise to visualize. We tried to develop a CGI diaper but wow it was insanely complex.

I'm optimistic about the future of the space since there is so much design territory to explore in terms of workflow improvements. But I still love something real - my wife is shooting a story for a national magazine today on a local woodworking artist and I know it could never in a million years be automated. The more that computational photography advances, the more important meatspace photography will become.
For anyone who wants to know more about Courant’s life, the people he crossed paths with (which include some of the great mathematicians of the 20th C), and how NYU came to have the Courant Institute, Constance Reid’s biography is and nice read.
I've seen this repeatedly with Apple Maps. You consistently get a "simplest" (although not labelled as such), a "shortest distance" route, and a "fastest" route. I've consistently noticed Google Maps hyper-optimize for time but you end up with slightly crazier/higher # of turns. Also, Apple Maps re-routing tends to take the hint that I want to stay on a main round around a residential neighborhood vs trying to constantly re-route my down a side street. YMMV, but I actually prefer Apple Maps c.a. 2019+
>"Footer" is a page/section element, not an in-text document relation. Footnotes are document or article relations, similar to sections or figures. The refer between the main text and supplemental material, with enumeration

Most words have more than one meaning - the one you give for footnote is certainly one meaning of footnote, however if I go to https://dictionary.cambridge.org/dictionary/english/footnote it says "a note printed at the bottom of a page that gives extra information about something that has been written on that page" which I actually think is the commonly understood meaning.

This would also explain the strong relation between the words Footer and Footnote.

The Footnote was invented in a particular media, it was presented in a particular way that was suitable to that media. My main point is that there has not been an obvious way to translate between how it is used in that media to how it should be used in the browser, and therefore attempts to make a footnote element specification have met with lackluster response at best.
Sure, their primary preference would be to use in-house, but their flagship products today are being built using either an old or a problematic process node and that's a big problem that is not going to get sorted in 6 months.

Reading the earnings call I think its reasonably clear that they will be going outside for at least some of their manufacturing - the 'contingency plan' is really around what happens if things get worse.

Ever seen the digital price tags at Kohl's? I can imagine a scenario where you walk in and the prices change!

More likely, though, it would be pricing things differently at stores based on demographics. Regional grocery store chains do this - We have Stop & Shop here in New England, and if I go to a store closer to an urban area, the prices are lower on some items and higher on other items.

I think the surface mostly depends on how much you want to give the sandboxed application, not on the sandboxing technology you choose. If want to build something emulating the capabilities of a desktop operating system including gfx acceleration (e.g. webgpu) then it will be much larger than some isolated compute function in the fashion of network edge workers.

I agree that an ASCII diagram helps concentrate on the content by making the attention to the irrelevant impossible.

But it's way clumsy and hard to edit when you need to change the text and move the boxes because of that, making it... not the best tool for the job.

I would take Graphviz [1], or went to https://plantuml.com/ and drew a nicer diagram while using fewer characters. Also, a much more easy to edit one.

So no, don't take "the worst tool for the job" unless you're masochistic.

Instead, realize what the job is really about, what is important and what is not, and then take the best tool for that important part, which would free you from ever having to deal with the irrelevant details.

I personally like the approach that Gwern takes (e.g. [1]), which works fairly well on screens where you have a lot more horizontal space than needed for the main body of text (it's beneficial to keep the text somewhat narrow anyway, since lines that are too long become harder to scan/read).

It seems to be somewhat similar to what Edward Tufte does in his books, which is also putting the footnotes in the margins close to where they are brought up, and often even interrupting the current line for an additional note or image at the point of reference.
