IMO, the calculus is taught incorrectly. It should start with functions and completely avoid sequences initially. Once you understand how calculus exploits continuity (and sometimes smoothness), it becomes almost intuitive. That's also how it was historically developed, until Weierstrass invented his monster function and forced a bit more rigor.

But instead calculus is taught from fundamentals, building up from sequences. And a lot of complexity and hate comes from all those "technical" theorems that you need to make that jump from sequences to functions. E.g. things like "you can pick a converging subsequence from any limited sequence".

I don't follow.

The fertility rate has decreased significantly for US-born women of every race and ethnicity since the 1990s. I couldn't quickly find good stats on trend in birth control usage or labor force participation by race, ethnicity, or immigration status, but I'm skeptical that the trend is in the opposite direction for any particular demographic.

So I expect the claims in my previous comment still hold even for, e.g., native-born whites as a subgroup: flat-to-decreasing birth control usage, declining labor force participation, but still declining fertility rate. Obviously the magnitudes of those changes may be different at the subgroup level.

yeah exactly. For some people, this was like enjoying a puzzle. And now there's an AI that can solve the puzzle -- it defeats the purpose.

However, if your point was to "make more widgets faster" and only saw programming as a means to an end (make money, increase SaaS features), then I see why people are super excited about it.

I see it the same way as cooking. If your goal is "sell as many hamburgers as possible" then the McD / factory farm is the way to go. If your idea is "I enjoy the personal feeling of preparing the food, smelling the ingredients, feeling like I'm developing my craft of cooking, and love watching someone eat my hand-prepared meal", then having "make fast food machine" actually makes things worse.

I think a lot of people in this forum are at odds because some of the people enjoy cooking for the experience, and the other half are just trying to make food startups. Now they can create and throw away menu items at record pace until they find the one that maximizes return. They never wanted to cook, they just wanted to have a successful restaurant. Nothing wrong with either approach, but the 2nd half (the software is just a product half) were hamstrung before, so now they are having a moment of excitement as they realize they don't have to care about coding anymore.

I 100% guarantee that most of the MBA / startup founder types who didn't love coding for its own sake kind of felt a huge pain that they had to "play along" with devs talking about frameworks, optimal algos, and "code quality" and the like, all while paying them massive salaries and equity stakes for what they saw as disposable item to increase revenue. Meanwhile the devs want another 2-weeks and 6 figures of salaries so they can "refactor" for no visible difference, but you can't complain because they'll leave.

Now that the code factory is in place, they can focus on what they really want, finding customers for an item. Its the drop-shipping of code and software. The people using drop-shipping don't care what the product is. Production and fulfillment are just impediments to the real goal -- selling a product.

The actual revelation of AI, if one can call it that, is how few people care about craft, quality, or enjoying work. Watching AI slop videos, ads, and music makes one realize that true artists and craftspeople are still incredibly rare. Most people are mediocre, unimaginative, disinterested, and just want the shortest path to easy riches. While it sounds negative, its more like realizing most people aren't athletes or interested in very difficult physical exertion -- its just a fact of human nature. True athletes who love sport for its own sake are rare and in a way nonsensical on their face.

In the end, we will probably lament something we lose in the process. The same way we've hollowed out culture, local businesses, family / relationships, the middle class, etc all in the name of progress before. Surely each step has had its rewards and advantages, but Molloch always takes his pound of flesh.

indeed. my credit card requires me to preload money from my bank account. it's like there is a second account that keeps a balance that i can spend using the credit card. whenever i use it, the balance is updated. how the credit is paid off i don't know. it could be either right away, or the amount is just hidden by my bank until it is time to pay off at the end of the month. either way, the credit limit is zero. so i can never spend more than i put in first. (though this may be based on how much i spend or be a configurable value.)

Monetary incentives are the foundations of Capitalism. There are only two ways that ethics might get in the way of their profits.

The first is government regulation. We saw lots of deregulation of oversight over the ten years before the 2008 financial crisis. None of the ethically compromised C-suite folks went to jail for their behavior because it was suddenly not a crime. Sometimes you have regulation, but you don't have enforcement of the regulations. This is what we get when the government is comprised of or controlled by capitalists. It's called fascism.

The second is public boycott or revolt. Could the new Target CEO be the result of the recent boycott? Same with Starbucks? Has anyone actually bought a Tesla in the past year? The big tech folks are bending over backwards to hide the fact that they have no real AI business model, making it a gigantic bubble that is about to burst. There is a national frenzy that no one is reporting on people ditching their subscriptions. We are going to see affordability get worse very quickly. It will be interesting to see what happens as more and more people start tightening their purse strings, whether by choice or necessity.

Custom pricing contracts are always where things get messy!

The default behavior for a downgrade is to start denying usage if a hard limit has been set and the usage is over the new plan's limit.

Limitr is entirely event-driven though, so adding a handler with custom downgrade logic is straightforward.

A lot of use cases can be implemented with soft limits also, which allow overage and emit overage events that you can charge for or handle gracefully (user notifications, model downgrades, etc).

In these cases, what is the desired behavior for you?

I'm guessing US will be fuming about this.

One not-so-fun fact is that when the US sanctions anyone, their ability to transfer and use money via Visa etc. is taken away. In the modern world, being cut away from even using your debit card is a huge, massive hassle.

It is one of the many different ways being sanctioned makes life more difficult. I can't imagine the US being too keen on giving up those powers.

So, don't fuck around with your phone while driving. Stick to the traffic rules. Avoiding him seems really, really easy.

Anyone who chooses to grab their phone while driving a car deserves all the negativity they get. Unlearn that habit. Seek help if you're addicted to that device. Or just take the Tube.

Depending on your appetite for risk, there's always the gray market. It's also a lot cheaper depending on what your insurance covers. I think I picked up a year's supply of semaglutide for under $200. I've been on some form of GLP for the last 2 years and for me there have been several tangible benefits related to ADHD.

https://gray.guide is a good starting point.

Alternatively, use them pseudonymously? There's little reason any of these companies need to know your real identity. This will both reduce the likelihood of ICE finding your account from a real-life interaction, as well as reduce the likelihood of ICE finding your real-life identity if they do get your account data (they'd at least need to dig through it more than just going by first/last name on the account itself).

Not who you asked, but I decided to try F# after reading “Domain Modeling Made Functional” which uses F# and is one of the best books I’ve read on domain driven design. I cannot recommend it more.

That being said, F# wasn’t really for me and applying the ideas from the book into other languages has been a better fit for me.

Similar 80s/90s upbringing for me.

The car thing is also limiting on who can perform extra childcare, and how/where.

As a kid, I used to hang out with my 10+ years older cousins who could drive - taking me to mall/movies/arcade/sports games with them in their little 2 door coupe.

Sure they were babysitting me, it wasn't some tremendous chore of being stuck in some kids-only space. They were doing stuff that they might have done without me, and probably got $20 from my parents.

We'd go see a Jim Carrey PG-13 film, not some Disney movie with they boyfriend/girlfriend/buddy, and they'd cover my eyes when their were tits on the screen. Or I'd sit in an older cousins lap at a ballgame while they drank beer (and smoked) and shouted at the players.

Can't imagine this is acceptable or normal now, lol. But it meant different generations commingled in ways that they just don't now.

> Seems to lack any internal moral compass, basically if the website lets him slander or lie it must be ok because he has no capacity to assess that value for himself.

As deplorable as that behaviour is, it mirrors how many of us, employees, are expected to function. Since Milton Friedman's 1970 doctrine, generations of business leaders have been thought that their sole social responsibility is to maximise shareholder profit. This assumes that any profitable action is inherently good for the society otherwise the government (like TikTok here) would have already forbidden it through law. This mindset trickles down to employees, if an action isn't explicitly discouraged by law, it is ethically permissible in the pursuit of result.

If agents can generate text so easily, why would they be limited to Markdown instead of reStructuredText, AsciiDoc, or LaTeX which have rich features that help users understand text? I can understand developers refusing to adopt proper formats for documentation, but this seems odd for the bots. It doesn’t even generate the correct syntax block in Markdown using “bash” instead of “sh-session”.

I grew up in the rural South (America's Third World) (N. GA) in the late 80s / early 90s and tons of children were born out of wedlock because kids were bored and fooling around. Bored, horny kids like to have sex. Now there are so many way to occupy yourself digitally that I think these is happening less. It's not that poorer areas are dumber, it's that they had less access to entertainment and sex is free.

I’m very much a proponent of statically typed languages and primarily work in C#.

We tried “typed” strings like this on a project once for business identifiers.

Overall it worked in making sure that the wrong type of ID couldn’t accidentally be used in the wrong place, but the general consensus after moving on from the project was that the “juice was not worth the squeeze”.

I don’t know if other languages make it easier, but in c# it felt like the language was mostly working against you. For example data needs to come in and out over an API and is in string form when it does, meaning you have to do manual conversions all the time.

In c# I use named arguments most of the time, making it much harder to accidentally pass the wrong string into a method or constructor’s parameter.

> Not really

This made me actually laugh. A drug that cures obesity and addiction alone would be a wonder drug.

This one also improves about a hundred odd immune disorders, including being a better general allergy drug than just about anything. My own extremely rare and terribly painful immune disorder is basically entirely cured by it - it completely changed my life, making even sleeping far better. But not just me, I have friends who have lifelong terrible allergies gone, lifelong pack-a-day smoking addictions completely gone, and so on...

"Not really" is truly either the most pessimistic take I've ever heard, or hopefully just completely misinformed.
Show HN: Cosmic CLI – Build, deploy, and manage apps from your terminal with AI
by tonyspiro | 2026-02-10 19:01:50+00:00
Hi HN, I'm Tony, founder of Cosmic (a headless CMS). We just open-sourced a CLI that covers the full lifecycle of a content-driven app from creating the content model to deploying to production to updating the codebase all without leaving the terminal.

Here's what the full workflow looks like:

# Create a project with an AI-generated content model
cosmic projects create
# → "A recipe blog with recipes, categories, and authors"

# Generate content
cosmic content -p "Create 5 recipes with images across different categories"

# Build a full-stack app wired to your content
cosmic build -p "A modern recipe blog with search and category filtering"
# → Generates a Next.js app, pushes to GitHub

# Deploy
cosmic deploy start --watch
# → Deployed to Vercel

# Later: update the existing codebase with natural language
cosmic update recipe-blog -p "Add dark mode and a favorites feature" -b feature-branch

# Create a PR and merge
cosmic repos pr create <repoId>
cosmic repos pr merge <repoId> 1
# → Auto-deploys to production

That's the part I think is interesting: it's not just one step, it's the full loop. Create content, build the app, ship it, iterate on it, merge and redeploy. Each step is a single command.

A few of the more technically interesting pieces:

AI agents. You can create three types: content agents (CMS operations), repository agents (code changes on branches), and computer use agents (browser automation via Puppeteer with AI vision). Chain them into multi-step workflows with scheduling.

Interactive shell. "cosmic shell" drops into a REPL where you navigate workspaces and projects like a filesystem: cd, ls, pwd. System commands with ! prefix. No cosmic prefix needed.

Multi-model. Supports Claude Opus/Sonnet/Haiku, GPT-5/5.2/5-mini/4o, and Gemini 3 Pro. Set a default or specify per-command.

It also handles the day-to-day stuff you'd normally do in a dashboard: billing, team roles, webhooks, domain/DNS config, environment variables.

Built with TypeScript and Commander.js. MIT licensed.

Right, standalone binaries for CLI tools is great. And if one has Go installed, they can just `go run ...` any tool from its GitHub path, all installation/build/caching happens automagically (meaning the execution is immediate after the first run).

But I can definitely see how someone with `uv` muscle memory wants everything in the same command.

`uv` is the best thing that happened to the Python ecosystem since... I don't know... maybe Numpy.

Cartels are not at odds with libertarianism. In fact, freedom of association is the fundamental underpinning of libertarianism. Unions are the libertarian solution to labour woes. Other groups normally favour regulation instead.

Libertarians don't have a theoretical problem with cartels because if a cartel tries to push for above-market prices, someone else will swoop in and start doing it for less, taking all the cartel customers with them.

At what point do we start to re-evaluate and re-test old assumptions about how much weight/caloric restriction impacts things? It seems unlikely that a molecule that slots into receptors in the pancreas also does something(?) to cardiac muscle [1], addition [2], and now osteoarthritis(!).

This feels like a stretch to say that this happens independent of weight loss, and much more like we may have underestimated the impacts of weight loss on all of these other facets of life.

While lighting is important, not using halflife.wad and going above the
original budget of 500 polys per "scene" is what makes modern works look much
better.

Most of the original textures are under 128×96 px and some suffer from awful
palletisation artefacts with purple and orange halos.
We still cannot use more than 8 bpp but we can use 512×512 textures and do a
better job at reducing to 256 colours. I use pngquant for that.

In GoldSrc lightmaps cannot get more intricate though, they're tied to the
texture scale so you cannot get a finer lightmap unless you also make larger
textures and scale them down, and these two combined will wreck your
"AllocBlock" budget in which all your textures and lightmaps must fit.

ericw-tools and its dirtmapping are still welcome improvements over the
"traditional" *HLT compilers.

Yes, exactly!

A common theme among these weird ideological group-thinks is political undertones.

> "Today, criticism on brutalism and modernism is mostly voiced by those on the far-right side of the political spectrum, precisely because of the association between modernism and the post-war welfare state"

Per the studies that I have seen over on Fertility Twitter, none of them seem to really make much of a difference.

Right now they are on a meme where they want to turn large tracts of national parks into suburban developments because some study said that apartments are bad for families. I ... its ... yeah...

All the studies seem to contradict, meaning that likely they are having little to no measurable effects.

'Yeah, we just need to try harder though'.

I mean, yeah, we're mostly trying to exhaust those 80-20 effects right now and see if anything sticks. From the little I have seen: nope. It's the proper way to look at it. Go for the cheap stuff with big effects, then see.

But you're right, it may be more like a 99-100 thing, where you kinda have to get it all right before it kicks off. We don't seem to know right now and are still exploring the space.

The point isn't whether the subsidy is for the destitute. It's whether it matters for incomes below the living wage or poverty wage. You can't buy milk and bread with a school voucher and the meager child tax credit is a pittance compared to the cost of raising a kid. It's just not relevant to wages below a living wage. Also, what makes you think the numbers for living wage with children don't include those pittances? Child tax credit would make about a $1/hr difference even if it isn't accounted for. We still have a complete failure of a safety net and a failure of basic minimum wage in the US.

> the value of that asset is at least the amount you borrowed

That assumption isn't true. Loans are made based on the expected ability to repay collateral is just one optional and partial way of reducing the lenders' risk.

Let's imagine that Debtor borrows $5,000 and offers up a Child's Tricycle as collateral. Lender was fine with no collateral, but accepts it anyway because why-not.

Do you truly believe that Child's Tricycle is "worth at least $5,000"? If someone offered it to you for a mere $1,000, would you eagerly fork over your own money for a can't-miss chance to make massive profit? Hopefully not.

The scenario becomes even spicier by substituting the weird asset with a "Mystery Box" of truly-unknown contents, and we haven't even started to talk about collusion between the Lender and Debtor.

> So just use that amount.

At this point, you're probably thinking: "Very funny Terr_, but we both know the Child's Tricycle wasn't covering the full $5,000 loan here."

Well, yeah... but what math did you use to determine the proportion?

You almost certainly applied your own independent judgement of what an arbitrary Child's Tricycle "should" fetch in some hypothetical future! I think that's reasonable, but it disproves the claim that we can just go off of the loan details.

"... HBR found that companies are cutting [jobs] based on AI's potential, not its performance.

I don't know who needs to hear this - a lot apparently - but the following three statements are not possible to validate but have unreasonably different effects on the stock market.

* We're cutting because of expected low revenue. (Negative)
* We're cutting to strengthen our strategic focus and control our operational costs.(Positive)
* We're cutting because of AI. (Double-plus positive)

The hype is real. Will we see drastically reduced operational costs the coming years or will it follow the same curve as we've seen in productivity since 1750?

Yes, this is a class of thing that is obviously being studied. Check out tesamorelin etc. but there is also a Phase 1 somewhere for BPC-157.

The peptides themselves are being used for everything but realistically, considering the costs, you have to innovate a little. Here’s a little example with GLP-1: the core biology and mechanism were well understood. But use was like the grey market peptides you were talking about: a daily injection. Half life is super short because DPP4 chews through.

So you need some innovation first to make it last so that you can bring it to market. Perhaps they misread the market and didn’t realize that for sufficient weight loss people would inject daily. But anyway, the liraglutide, dulaglutide, semaglutide, are various attempts at this to preserve function while raising half life in the body.

If you want to accelerate this research you’re really going to have to reform the whole process of medical testing and this and that but most things are not so dangerous that you need to rush to release a drug. Not everything is COVID-19 or obesity. Getting a PDA trial so some few people can heal faster from workout injuries is probably going to be a hard sell, even on this forum.

I’m of the view that the combination of grey market and clean market supply is a great way to serve latent desire as well as safe mass access.

One funny thing that a researcher told me (on seeing my lab notebook of my retatrutide self tests) is that it complicates baseline wide population studies. The total population is also losing weight, not just known GLP-1RA users. It turns out grandpa and grandma are reconstituting vials with BAC in New Salem, Oklahoma.
