The code base had multiple problems, none of which I would blame on category theory or Cats.

- Engineers had written higher abstractions seemingly just because they could. When I audited how internal libraries were used across our services, calling applications weren't making use of the advanced abstractions. I'm talking about things like using Cats to abstract across AWS S3 error handling. Cool, except that it wasn't needed because we never actually encountered the exotic compositions of failures anticipated by the libraries.

- The abstractions written for our own business logic were worse than abstracting over S3. They were premature. Our business logic had to change frequently because the end user experience was still evolving rapidly. Changes that violated previous assumptions and their corresponding abstractions took longer than they should have and/or led to very awkward code.

- At least at the time, tooling had more problems with the "advanced" code. The IntelliJ IDEA Scala plugin could not yet show how implicits were used. It couldn't find senders sending to an Actor the way it can easily find plain callers of a function. You would need to manually force a "clean" in certain modules before code changes would compile as expected. IDEs would also fail to flag code that couldn't compile, and incorrectly flag code that would compile, at a higher rate compared to plainer Scala.

I'm still glad that I have access to Cats, Akka, and other advanced parts of the Scala ecosystem. They're still used in a few places where their value is greater than their cost. Even in the plain code, I'm still very glad I have pattern matching, immutability-by-default, rich collections, map, flatMap, filter, fold, scan, find, etc. I have no plans to transition our company off Scala internally. If I were starting a greenfield project with myself as the sole developer, I'd probably be using Scala for that too. But I prefer to write a bunch of simple repetitive code first, then develop abstractions after it's clear what the commonalities are.
It seems to me that i, j, and k are three things that have the same property, not three identical things.

What we need is tools that help individuals plug in their budget and track how inflation affects them. These overall inflation figures are pretty much useless because they have to exclude information in order to not be too highly amplified in either direction. Creating a budget of how much I typically spend on food, gas, utilities, and such and being able to backtest that budget would be really helpful, and perhaps that data could be used to crowdsource inflation figures that are more representative of what the average person is actually experiencing.
Ask HN: If money were not an issue, would you be a solo indie game developer?
I would say it was the optimism around computers in the 1980's and early 1990's. People were optimistic since a relatively inexpensive computer was an enabler. In some cases, it eased the process of getting stuff done. In other cases, it gave people the tools they needed to do things that they would otherwise have to invest in expensive training or equipment to do. Then the cynicism of the past decade set in. I find it is now nearly impossible to see the positive contributions of technology even when they exist.

(That is not to say those earlier times were entirely positive. People were still trying to build corporate empires, or otherwise use technology to the disadvantage of their customers. Yet the balance of power seemed to be better balanced and it felt easier to walk away from it all and still lead a good life.)

The standard two components of inflation are money supply + velocity of money (how often that money changes hands).

Inflation is roughly defined as more dollars chasing the same quantity of goods leading to price increases. It's clear how printing more money would lead to that, but what if the Fed prints more money and it just sits in bank accounts? Hence the velocity component -- people need to actually spend the money for inflation to come into play.

The confusing thing now is that since the US has been in a liquidity trap for a long time, velocity isn't even the right measure. This is a mirror of what happened in Japan in the 1990s and is still happening today;

Yikes! This is the sort of thing that scares people away from complex numbers from a young age.
You're noticing what's gone up. I just did a Home Depot run and everything there was the same price it was last year.

A 7% inflation rate is not everything going up 7%, it's a small number of things going up a lot. The human mind is a lot better at noticing things that change rather than things that don't, so inflation always seems larger than it is.

Did you mean, "infantilizing"?
No, i, j, and k are not the same thing. They are the three distinct square roots of -1. You thus wind up with a space with one real axis and three orthogonal imaginary axes.

Why should -1 have three distinct imaginary roots? Well, why should it have one? Essentially, we just made up i, and we found out that the complex numbers had some really useful algebraic properties. The same is true of the quaternions.

But why not two imaginary roots, or four, or 17? Those turn out not to have nice algebraic properties. The only other thing out there are the octonions, with 7 imaginary roots.
> 18 minutes of advertising per hour of TV.

It's a feedback loop. Audiences increasingly switch to streaming, so companies are willing to pay less per a second of advertising. TV stations increase the amount of time dedicated to advertising to compensate, which drives more of the audience into streaming.
You jest, but I've heard a tale from a local engineering college: they regularly give to the graduating-year students a task to design some system which, after you remove all the fancy wordings, is basically insides of a toilet cistern/tank. Year after year, the students keep producing astonishingly convoluted designs.

"Anyone with a web browser knows that home prices have experienced a monumental increase."

An asset cannot experience inflation. The word inflation suggests something that loses values. A home that gains in value is clearly not suffering inflation, rather, that is the opposite of inflation.

If you earn $200k a year, and there is 5% consumer inflation, and a year later you still make $200k, then in a sense you are 5% poorer.

If you've a house worth 200k and its value goes up 5%, then a year later you are 5% wealthier.

We might joking and informally refer to "asset inflation" but please remember, under any formal model, there is no such thing; it would be a contradiction in terms.

Perhaps slightly off-topic, but as someone who has spent most of my time living in European cities these house sizes are just mind-blowing to me.

1500 sqft is 140 m^2, my first apartment was 30m^2. I can't imagine what you would put in a 3500 sqft (325 m^2) house, never mind something like answering the door if you were at the other side of your house.

Everyone already knows this in a vague sense, and in fact that's a large part of the problem. If they weren't aware of this they'd at least be more likely to consider both sides, instead they can just say the statement they don't like is the inaccurate one while blindly accepting the statement they agree with is not.
> That will disproportionately affect lower income households who can't as easily withstand these rising costs, which further drives income inequality.

I see your compassion, but income inequality isn't driven by prices, it's driven by the employers not paying enough to their employees. Prices can't fix that.

The extraction is a small problem. The global warming it causes is the large problem. Less pumped oil means less burned oil which means fewer greenhouse gases.
Constricting the pupil can certainly reduce the effect of defects in the eye lens by reducing the amount of lens used; however, it won't work well in dim light.

Alternative: Increase environmental lighting and use bright, high contrast displays with dark text on bright backgrounds (no dark mode). This will not just constrict your pupils (as the eyedrops do), but also increase the rate of photons reaching your retina in bright areas of the scene relative to dark areas (in other words, improves contrast, which the eyedrops won't do).

Thanks. Another number to watch is core inflation in the last 2 years. From a few months before covid to the latest number: Nov 2019: 265427, Nov 2021: 283201

Annualized Core CPI is 3.29%. +1.3% higher than the target.

My first order guess is that Fed will decrease asset purchases gradually and an interest rate hike in the next summer might happen if the long-term core inflation is higher than normal. This seems to be what they are communicating.
This is the entire point! Let the market provide the different things people want. No one is telling ranchers in Montana that they have to live in a walkable neighborhood in San Francisco.

I think perhaps you're giving too many people too much credit. I would assume that the vast majority of people in the USA think it's a functioning democracy, subject to the rule of law, with human rights.

Wait, you're predicting 40% inflation in the US over the next few years?
Core Inflation is needed so that they can apply the right monetary policy. If you want your 'personal' inflation, they have data for that too.

Fed releases all kinds of data (unemployment and monetary) and is pretty transparent.

I'd add another sentence to that:

"Understand that even with the best intentions you'll likely still get it wrong."

Objective truth is incredibly unwieldly. It's almost impossible to get right - just considering imperfections in communication alone.

Ever play the game of telephone? One person tells a fact to someone, who tells that fact to another person. Go 3 hops and you're almost certainly going to end with a different fact than you started with.

Each step of knowledge transfer incurs loss - and this applies to all forms of communication.
No.

Because if money were not the issue, all that's left as a motivation, would be to build a product gamers love and care about. This means competing in a market that literally measures the seconds of peoples attention certain products get.

> hurts a lot of people with mortgage

How so? The only downside (for people who already own a house) I can see of building more housing is that prices wouldn't rise as much as they historically have. AFAICT rising house prices only benefit real estate speculators, not actual homeowners who live in the house - my taxes are a percentage of the appraised value of the house, and they go up every year to the point where I'm starting to wonder if I'll be able to afford them in 10 years. I can't really "cash out" the value I have in the house either - or I could, but then I'd have to buy another house to live in at the same inflated prices.
Are you really saying the appropriate response to a "political opponent" trying to stop you from being elected is murder?
What I am saying is, it's not just that: the article is not wholly rubbish. It is written (paradoxically) for a public that excludes some more "normal" languages.

Even that "integrate into the tribe": there exist plausible interpretations, such as "creating a communication that spreads truths, creating further building blocks for further commonality and keys for further communication".

It is also true that to play squash, spending hours to throw balls at a wall, will get frustrating if you wanted them balls to reach the other side. If you want to be understood by someone specific, you have to understand that - unfortunately - there exist a large number of people who will only understand a limited number of message forms.

Thank you. That was one of the most interesting article I've ever read from HN
Video games.

I'm surprised no one has mentioned this yet.

There's simply too much money nowadays in micro-transactions, in-app purchases, loot boxes, pay-to-win and in-game advertising that almost everything is "free" to play and it's literally horrible.

what we have now is mostly copy-pasted franchise titles (with a year after their name) that are just another optimized hellhole of extracting money from you a small slice at a time.

There are exceptions and this is part of the reason why Nintendo as a brand is still loved by many. I consider Zelda Breth of the Wild to be one of the most amazing games and experiences of my video gaming life.

I also like board game adaptations to mobile because they tend to be limited in in-app purchases.

Other than that? By God, there's a ton of crap out there. It's no surprise how many people will go to great efforts to play games that are 20, 30 or more years old now.

>"Teaching critical thinking at schools"

This is everyone's go-to answer, probably because it seems like an obvious magic-bullet solution. If only we taught critical thinking, people would actually act intelligently as adults!

I must ask, is it really the case that critical thinking isn't being taught in schools today? The idea of teaching people how to think critically isn't some revolutionary new concept, this has been around since antiquity.

I suspect the answer is that despite trying to teach critical thinking skills, we are all still human and fall back to relying on our cognitive biases. I sense the problem of "making" critical thinkers is just as hard as teaching kids to be healthy. "If only we taught children to eat healthy and exercise in schools"
Yeah, that is because emails are generally longer than typical chat messages. If you try to display a series of replies directly as a chat it will look poor. Scailer resolves that problem. We created a unique algorithm that transforms a series of replies to a sequence of related well-readable posts about the subject.
As long as you wanted the product and got it in exchange for money, anything the company says can be safely ignored.
That's an interesting argument, we tend to use 'belief' to mean 'uncritical acceptance' though? I am also skeptical about how much critical thinking is imparted in typical US curricula - there's a ton of rote learning, and a lot of socialization to encourage you to follow instructions, work in teams, etc. (which is of course good training for the workplace, where there's even less room from critical thinking, typically). But there's no doubt that the more traditional and conservative a student's background is, the less excited their family will be about them asking tough questions. For kids whose families will let them (and can afford it) that freedom tends to happen in college.
I think a major part of "Built to last" is repair-ability.

If you can fix it, you've kept it from the trash. That's one thing I learned a lot about as an AV service tech -- some companies are happy to sell parts or service a 10 year old unit ( a third party market for OEM parts is almost better). Some won't pick up the phone and expect a thing to be thrown away.
