> But the error propagation is not transmitted by the significant number. x, y being written with the correct number of significant number will not lead to f(x, y) being written to the correct number of significant number.

Significant figures are not a convention for making your deliverable pretty. They have semantic meaning. Don't think about dumb rules from high school chemistry, think about the actual problem. There are two entwined sources of uncertainty I am referring to:

1) measurement uncertainty, due to a lack of precision in the instrument (or the quantity itself, e.g. many financial computations are not meaningful if they involve fractional cents)

2) computational uncertainty, which is exclusively due to algebraic propagation of measurement uncertainty

Far too many data scientists don't care about the first category of uncertainty because they don't care about where the data came from. And they don't even realize the second category is a problem.

Let's look at a specific example. Somebody tells us that they measured the side of a square as 1.0m. Their tape measure only went down to centimeters, so the uncertainty is +/- 0.01m. What is the area of this square? Let's look at it two ways:

1) The smallest possible side length is 1.00m - 0.01m = 0.99m, so the smallest possible area is 0.98m^2. The largest possible side length is 1.01m, so the largest possible area is 1.02m^2. Thus the area is 1.00m^2 +/- 0.02m^2.

2) The side length is (1.00m +/- 0.01m). So the area is

(1.00m +/- 0.01m)(1.00m +/- 0.01m) = 1.00m^2 +/- 0.02m^2 +/- 0.0001m^2 ~ 1.00m^2 +/- 0.02m^2

So the uncertainty is not +/- 0.01, it is +/- 0.02. This can add up quite dramatically. In general if you have x +/- delta, then f(x +/- delta) is not going to be f(x) +/- delta or f(x) +/- f(delta). It needs to be handled carefully.

The idea of plainly stable and unstable points only happen if you have rotational symmetry, and doesn't really apply to most of the points. Leading the discussion on those terms isn't productive.

It orbites in a plane where it's always subject to attraction, but that doesn't mean the point always attracts the satellite.
Small claims court has very low limits. Beyond that, it’s very easy for a large company to make a lawsuit cost more than it’s worth - you’re paying court costs up front, they’re going to litigate every single detail to say that you didn’t complete everything (both to lower the total and to prevent you from being able to do full time work for someone else), and delay things hoping you’ll give up or make some mistake.

It’s not super common but every freelancer I know has a client from hell story. The abusive ones get pretty good at calibrating the amount they can screw someone out of while still being only marginally worth the cost and effort of suing.

The Roman empire may not have much of a legacy in mathematics, though they did continue Greek traditions of philosophy and even had 'philosopher kings' [0], but they were very much leaders in engineering, and the legacy of Roman ingenuity is still alive today:

The influence of Roman roads can still be seen today [1], Roman concrete is still studied by modern material scientists for its properties [2], the Pantheon is still the largest concrete (only) dome in the world [3], and even the width of modern railroads can be traced back to Roman road standards [4]. That's not even mentioning aqueducts, some of which still stand today, that brought unknown levels of sanitary hygiene to cities at the time, or the fact that civil engineering wasn't even the main focus of Roman engineers (who were by and large associated with the military, often enabling the legions to beat impossible odds [5] and displaying a fairly modern understanding of the importance of logistics [6]). Like it or not, Rome was a STEM powerhouse, despite its lack of interest in 'pure' science or mathematics, and owed no small portion of its dominance to the prowess of its engineers.

To be fair, I believe the author is addressing a beginner audience for inexpensive displays commonly found today. These modern small displays have about 7 times more pixels than those older Nokia ones, which means the bandwidth to drive them in monochrome is the same as driving the color Nokia displays.

The advice of "if color, start with SPI" is simple and mostly correct. Good enough for a target audience of engineers just starting with hardware.
I'm sure there is corruption but I don't think it's so black. Where did all the smart Romanian emigrants I know go to school? How come there's 10x more fibre internet than in Germany? Things definitely could be better, but I don't think it's all bad in Romania and all great in say Germany.
It is a funny thing that I find in b2b vs. b2c.

If I want to buy some component as a consumer, they’re going to take payment up-front or tell me to screw off if I ask for them to send first and get paid later.

Meanwhile, receiving the product/service first and then net30 and such payment terms are common in North American business.

I do wonder if business works the same way in other cultures or if they take the approach that consumers typically deal with.

Contractors and suppliers often face payment issues globally.

In Texas, when contractors work on a property, they are entitled to lien rights. Normally, property transactions involve a title company. One of their roles is to ensure the clearance of liens and manage the escrow of funds, transferring the purchase money from the buyer to the seller once they have established clear title. Additionally, they provide title insurance to the new owner, guaranteeing a title free from encumbrances like construction liens. This process is crucial for safeguarding the interests of all parties involved in property transactions.

Its hard to tell who is in the right without more facts. But it is clear the way the transaction was handled is part of the problem.
These don’t need to be hugely punitive, just shift the economics enough to make doing the right thing less costly than the wrong thing.

What do you think the average revenue per customer is at Bandwidth or Twilio? A couple thousand dollars in fines for a violation should be plenty of incentive to screen their customers better.

If they start charging them $500k for a violation or something, these senders would just drop them entirely. Sure, you’d get rid of the junk… and everything else too.
I'm a professional designer. You're conflating learning design with learning a tool. Learning to use the tools is the easy part. Learning the fundamentals of design is often still taught in schools with pencils, paper, paint, collage, etc. and you'll almost never find a course on "Photoshop," for example. You might find courses on photo editing, and you might use Photoshop to do layout work for a class on making still composites, but knowing Photoshop doesn't make you a designer in the professional sense any more than knowing Word inside-and-out makes you a writer. Do yourself a favor and read some great technical design books like "Grid Systems," "Thinking With Type," and Alber's "Interaction of Color," as well as more general design books like "the design of everyday things" to get an idea of what design is before you start trying to mimic design with design tools. Developers especially tend to dramatically overestimate their understanding of design, and dramatically underestimate the amount of knowledge required. I think the "graphic design is my passion" meme is terribly reductive, but it is a thing. Formal training isn't magic: I knew a self-taught designer that became the art director for a national magazine. But you bet he read all of those books and dozens more— for every one like him, there's 10k people who gained technical competence with tools and have no idea that they have no technical competence with design, generally. You can quickly get yourself to the point where you're making logos for clients on fiverr who have no idea how to evaluate design, but most of those designers wouldn't even qualify for an internship at a design studio, let alone get contracted for work or an in-house position somewhere.

Hope this helps.

I often discover I'm going well over the speed limit when driving my Model 3. I don't think the lack of speedometer (that I can see without looking down and to the right) is entirely to blame - though its location not being in my line of sight doesn't improve things.

For me, it's the relative silence of going from 0-60 MPH in under 4 seconds that does it. I have an ICE car that can almost do that, but it does so very loudly requires me to shift gears manually as it happens. It's a full body and mind experience, one full of very obvious feedback.
> And what if we could deploy modifications to that datatype (ex. adding a database field) in the same uniform way we do all other minor variations to a datatype?

If you mean propagating changes to a schema across all layers of the stack, that may not necessarily be a good idea. In my experience we want to keep the datatype definitions at different layers somewhat independent of each other, to allow evolving separately. For example, the database table could have a `more JSON` column to allow adding data that was not foreseen in the original table design; but the application's datatype would decode that JSON into specific fields to show the user perhaps.

I don’t disagree in principal but what exactly is the alternative? Playing SuperTuxKart and Pingus or some other open source games all the time? I hate the “service-ification” of everything, but I think it’s a near-monopoly that’s kind of hard to avoid.

There’s sites like GOG that give DRM-free versions of games, and I like GOG a lot, but it’s still fundamentally a proprietary service that could shut its doors down tomorrow. I know that I personally do not have all my GOG games backed up, and I am one of the rare people that has enough disk space to actually do that, so I doubt I am weird here.
I have almost the exact same but with "--restrict-filename" lest you end up with emojis and other Unicode characters you do t necessarily want on your file system.
I guess this is a fundamental different between accrual vs cash accounting. In accrual accounting, you would book the revenue when the service is provided and delaying/advancing a payment shouldn’t change the fiscal year it falls under.

In Canada, most of the time you’re required to follow accrual accounting.

I guess if you have the choice and expect routine delays to payments, cash accounting is the way to go.
Maybe so. There is definitely a lot of confusion and misunderstanding for those that have only ever been taught and only ever experienced monogamy. I'm polyamorous but I find polygamy to be pretty vile. I've never seen polygamy mentioned or practiced outside the context of religion, cults, or seeing people as property. Polygamy almost never benefits all the people involved and when I've heard of it practiced in the U.S. it's often commingled with the absolutely vile practice of child marriage.

edit: I'm surprised this is an unpopular opinion, curious what I said that people don't like.
Engine, sure, but a Nissan/Datsun manual transmission is only like 80lbs, if that.
Conversely, Texas mechanics liens have little recourse when a property owner encounters a contractor acting in bad faith. I recently assisted a friend challenge an improper lien on their homestead in Dallas when a plumbing company quit the job halfway through because they couldn’t use their epoxy repair technique and walked away. The contractor filed the lien for the total amount agreed upon because state law makes it trivial to do, and it is an uphill battle to challenge a lien. It only worked out in the end because we had accumulated a paper trail via email and sms messages with the contractor, and reported them with said evidence to the state licensing apparatus.

If engaging contractors in Texas for property work, get everything in writing and have an attorney familiar with construction law at the ready.
I should hope a vague ritual invocation of pagan gods wouldn't be legally binding.

As a somehow lisp head, and even though I mellowed with time, especially about syntax, I still don't think there's anything wrong with sexps. It might be a neurological trait, some people just can't live with a syntactic layer.. their brain might rejoy with it, think clearer and faster. I, for one, is the opposite, it removes one dimension in the problem space, and structural edition is so cute. I also have a tiny personal bet that in 30 years, if people are still writing code.. someone will make sexps mainstream.. just like closures are now, just like tree processing / ast / transpiling is mainstream now.. it just take time to cook the mainstream.
It's not based just on statues and emperors, though that shouldn't be ignored. The Roman's never adopted the Greek gymnasium, instead opting to have enslaved Greek philosophers tutor them at home[0] so that they could feel cultured. None of it was real and after a thousand years of LARPing as Greeks the Romans made zero contributions.

There might be special exemptions, but in general what matters for transfer to employees is market value. Legally speaking, see e.g. this Irish documentation (first to show up in my Google search): "You might choose to give your employee an asset which has depreciated in value. Where this occurs the value of the benefit is the market value of the asset on the date of the gift." https://www.revenue.ie/en/employing-people/benefit-in-kind-f...
Same thing in Canada and UK, 3 out of 3 countries all do it that way (in general, Canada has up to 500$ exemption): "When gifting capital property to an employee (or anyone else for that matter), the proceeds of disposition for bookkeeping purposes is recorded as zero dollars. This, however, is not how the transaction is treated for tax purposes by the Canada Revenue Agency (CRA). This is because, the CRA sees the gifting of assets as have being sold for fair market value." https://www.koroll.ca/koroll-and-company-blog/the-tax-implic...

No luck necessary. It is inevitable.
Electroculture has a very long history dating back the to mid 18th century [1] but it's still a bit of a mystery. Quite fittingly the man who pioneered it, Jean-Antoine Nollet, also discovered osmosis which is probably why the method is effective.

The electrical current causes electrophoresis, which increases ion mobility and allows the roots to more easily absorb them via electroosmosis while also increasing ion exchange between insoluble soil particles and the water. On top of that the ions coming off the electrodes probably contribute since copper is a cofactor in many enzymes that effect photosynthesis, respiration, and signal transduction.

It doesn't always work though, depending on the soil, the electrical current use (strength and duration), and the species. Done incorrectly all it'll do is damage the root system and kill the plant.

I'm deeply cynical that polyamory is "popular" outside of select corners of the Internet. Why? I'm just going to be blunt and say it: very few men are going to tolerate a situation where their wife or girlfriend is having sex with several other guys and they aren't having sex with several other women for long. Given how supply and demand for casual sex works, that's going to be what happens, more often than not. This is the sort of situation that could turn very explosive, very fast.

And that's before we to whether most people are temperamentally suited to the emotions of "sharing" something this intimate, or the child-raising angle. Just because it can work for some doesn't mean it'll work en masse for most people.
That’s probably related to the decline in swinger culture following no-fault divorce.

I cheated hard on this adventure time card wars game. Basically they stored "gems" offline on the client, so instead of buying a few gems, I'd just set the value like gems=9999999.

The thing was that matchmaking would match you up based on how many gems you spent. It inadvertently just set us all up with cheaters. The free game was pretty meh, but cheater's hell was a lot of fun. Everyone had every card, so the only way to win was being good at the game. I'm rather sad they killed the game eventually, it was a pretty well designed game.

I think bot hell for chess would be interesting too, the game becomes who can make better bots.

You're gatekeeping a lot here. I realize that some poly people are much more dedicated to the lifestyle and truly believe in being able to maintain multiple partners. But there's no way to distinguish between that and the "we've been married for 3 years but we're turning poly" case, nor do you or I have the authority to say that's not really polyamory.
