My current daily vehicle does a pretty fine job of figuring out what mode I want for HVAC.

Sometimes, I do mash the defroster button when weather commands warm/dry air on the windshield and it's easy enough to find that with muscle memory.

Otherwise, in normal seasonal weather, it works well and I don't change modes or temperature. Windows up, down, hot, cold, sunny, cloudy, dark, whatever -- it all works about the same.

Previously, I drove an older version of the same vehicle. It also worked well until it forgot how to figure out what day it was due to a software issue. After that, it kind of had a mind of its own.

(Now, a sane person would ask why that would have to do anything to do with HVAC performance.

It gathered the current date, time, and position from GPS, the bearing from the nav's compass, and the solar intensity from a sensor on th dashboard.

A bit of math and/or an almanac lookup later, and it also knows the position and angle of the sun relative to the car.

So it knows when sunlight is streaming on through the driver's window, and adjusts automatically to compensate by providing relatively cool air from the dash vents only on that side. It also knows not to do this on a cloudy day as well as other things that seem obvious once a person starts thinking about them.

Which is a magical kind of automation -- until the calendar is off by both years and months because Honda broke the clock and its understanding of the sun broke with it: https://didhondafixtheclocks.com/ )

Sure, but have any made as much progress as Neuralink? Not a rhetorical, genuinely asking as someone who doesn't know much about this field. Though, even if others have, isn't this kind of technological achievement something to be lauded regardless of who owns the company that did it?
> Biology has a more rigourous definition for sex to avoid exactly these confusions.

You're right — here's a semi-old crash course on the whole topic from someone who is actually studied and practiced in the fields of biology and endocrinology: https://imgur.com/a/sciencevet2-on-science-of-gender-qmIiULb

The tl;dr of it is "the bimodal sex distribution model is really bad at a lot of the things we use it for, including predicting results to prescribed medication, or questions about who can give birth". There's some links to actual papers included in the gallery, if you want to follow this up further.

> I do acknowledge that even some biologists have fallen into this trap lately, to our detriment.

From 'knowing people in the field of biology', I can say rather clearly that it's less "some biologists are mistaken/foolish" and more "the majority of biologists who are up to date have decided to revise their beliefs about sex in line with current research".
So expressively and beautifully written.
I asked this question because we don't live in a communist society. No one owes me a job just because I exist. I get a job because someone wants to hire me, and if no one wants to hire me, then I will be unemployed. When unemployed, I would get some small government assistance money, just so that I don't starve to death, and I would get free basic healthcare (medicaid), but I would probably need to move to low CoL area, and give up any luxuries I can no longer afford. This seems fair to me, but I'm open to discussion.
You're right, but wasm's goals were never to be a mainstream way to write web applications. It was designed very specifically to allow things like Photoshop, Unity, and other high-end applications to run on the Web, things that just didn't run at all, and were really important. But despite their importance, those applications are a small fraction of total websites.

Wasm succeeded at its initial goals, and has been expanding into more use cases like compiling GC languages. Perhaps some day it will be common to write websites in wasm, but personally I doubt it - JavaScript/TypeScript are excellent.

> Isn't this just hindsight bias? You market time to right after 2008 crash.

Yes absolutely, I just picked when the product launched.

I wanted to point out to parent that the daily balancing isn't just a bad thing, it can be a good thing - it depends on how the underlying performs. You are right it cuts both ways though and you may have to sit in them for years to break even. Note UPRO actually somehow pays a dividend.

> If you bought 10x levered out of the money spy calls every 6 months and roll the winnings since 2009 you probably can get even higher, but probably you don't want to do that.

What do you mean by 10X leveraged calls? Like 10-delta? What was the spread between implied and realized volatility over that period? Ultimately your options outcomes are really based on realized volatility exceeding implied volatility (otherwise you break even or lose).

> Isn't this for retirement saving? IE where we have big chunks of cash we won't see for 20 years, so you can buy like 2 contracts and its good enough.

Parent said contracts that expire in 6 or 12 months on SPY. That means short term capital gains at expiry, and using SPY instead of SPX means you have to deal with early exercise and dividends.

Since you can't buy contracts too far out in time, so you have to sell, roll or exercise. In a tax advantaged account maybe that matters less. Was your proposed strategy to roll? If so, how far before expiry, and to what level?

> You'd have to pony up 2x to get the underlying index fund anyways, so you might as well just buy deep ITM calls (which right now are hovering at a premium of 3% for strike of 315$ on spy).

Over what duration? We need that to figure out the rough APR of the implied borrowing you're doing.

> +1 for European options, I forgot you can buy those on index funds...

On indexes not index funds! SPX option notional value is literally the S&P 500, in index points, times $100. They're big. XSP option notional value is basically the S&P 500, in index points, times $10.

> I thought margin / borrowing costs for future etfs is some ridiculous 8-12%. Pretty bad if you have no alpha except beta go up!

I was suggesting the underlying futures contract rather than a futures ETF. /ES is big, /MES is much smaller.
Wouldn't predicting the future at that scale automatically change the future and make it unpredictable again?

It is one thing to predict the future and have everyone not know about the predictions, but in a world where many people will be able to use LLMs to predict the future, the lower the quality of the predictions will be because they won't take into account that there are other agents predicting the future, which would influence the action of those agents, so you end up in a game theory scenario not that dissimilar from what we have now

I’m curious your understanding of what the essence of fascism is. To me an essential part is mega corporations colluding with the government to force the people to do something they want.

Public health concerns, valid as they may be, ought to be accomplished without this kind of coercion, yet I sensed a very strong “obey in advance” mentality permeating from mainstream media.

apparently, it’s anathema to even talk about this.
The Battle for Attention (2024)
> I'm truly sorry for all that you've been through and I hope you find comfort. Reading through your other post it seems likely to me that nothing you said or did could have made any difference.

Yeah I know, that's not really why I feel guilty, at least not exactly. I feel guilty because I noticed signs of someone who was suicidal, and explicitly chose to not do anything. Even if nothing would have changed, I still think I should have tried to do something, even if it was futile.

It feels like the universe was giving me a character test, and it feels like I failed it. I would like to think that when push comes to shove, I'd do the right thing, at least in regards to someone's life being on the line, but I guess at some fundamental level that's simply not true, or at least it wasn't in 2021.

I mean, I realize that no good comes from feeling bad about myself over it, certainly not for three years, but human psychology is pretty annoying sometimes.
Nissan Leaf has 2nd generation that is supposed to have fixed the battery degradation.
jj is nicer to learn first, but also, knowing both git and jj I do pick jj.

Significantly nicer UI, very simple but powerfully expressive DSLs for formatting logs and selecting revisions to log, respectively.

For me it clicked when I really grasped how the latter DSL (called the revset language) wasn't just for selectively logging, it was for selecting commits/changes to act upon. The revset grammar is about specifying subgraphs of the graph of changes. Using it, and taking advantage of jj's by-design automatic rebasing of downstream commits, you'll eventually think nothing of rebasing N branches in a single command.

Even conflicts are less trouble when they crop up during auto-rebasing. jj leaves conflicts on the change where they originated, and marks that commit (and all downstream ones) as conflicted. Fixing conflicts is no longer a "drop everything and fix" matter; you can decide when to fix them without delaying work on other parts of the tree.

Haven't even gotten into the optional auto committing on every file change (it's better than it sounds). You might miss the staging area for a bit, and then you realize that there isn't really a difference between the staging area and a "current commit" that stays up to date on its own.

I guess what I'm saying is I would recommend it.

WSJ is Diet Fox News, in print form. Murdoch owned. It's completely Trump aligned and untrustworthy on politics.

What If Laravel Had a ShadCN-Like Blade UI Component Registry?

Would you use this in your Laravel projects?
For what it's worth, don't do this, you also know you need to give people space and in hindsight, because of what happened, you only now think should've done something but I'm sure there were wholesome reasons why you avoided intervening in the first place.

Just as easily they didn't make the attempt and you would've thought you made the right call.

Show HN: HungryAPI – Plaid for AI Checkout
Hey HN,

We’re building Hungry-API, a checkout system optimized for AI agents. AI models like Operator can browse the web, but actually completing a transaction is another story. Websites aren’t designed for AI, and even something as simple as ordering a pizza online becomes a fragile, slow, and error-prone process.

Our demo shows this clearly:

* Operator on its own struggles to order from dominos.com—it’s slow, needs multiple retries, and breaks if the UI changes.

* Operator using HungryAPI on app.tryhungryapi.com completes the same order 10x faster and more reliably.

We solve this by acting as a Plaid for AI—-just as Plaid streamlined bad bank UIs for financial apps, we bridge messy web checkouts for AI agents. We still scrape websites when needed, but instead of brute-force automation, we provide a structured, AI-first way to complete purchases.

Would love to hear your thoughts! You can check us out at tryhungryapi.com.

Ask HN: Leetcodify business development as per YC parameters
YC has done a tremendous job democratizing and demystifying software business development. However, success in this area still has a ton of uncertainty. Honestly a lot of "ideas" being thrown around don't really hold any water and historical analysis would tell you that most ideas fall into a few buckets:

- hosted infrastructure

- digitize existing business workflows

- useful data analysis

I was wondering if there's a way we can build a Leetcode like system where we can analyze business theses with data like historical analysis, existing customer interviews and PoCs. We can all learn from it and solve this problem once and for all, so us engineers have a repository of useful problems that we can focus on.

Hmm - what is the actual cost incurred by the users here? Mostly battery right? Is that not virtually inconsequential to each individual?

I mean you could sum it all up and compare it to human-hours or something but that's not a useful metric because it's distributed.

Personally I think it's better to distribute the workload across clients. We'll probably see purely client driven UI's dominate the future. Imagine users being able to display data (because fundamentally that is all a blog [or any site] is) in a way chosen by each user. That would probably be worth the extra cycles on device.
When I was quite young but literate, I began investigating the paranormal. Snapped up books on UFOs, OBE, SHC, Astral Projection, Bermuda Triangle: all kinds of phenomena and ghosts and spiritism-age weirdness.

But being Catholic I was also going to a big fancy theater once a week where there was cosplay and fairy tales and lots of singing and a snack. All your friends hung out for coffee and donuts. And really that was my surface-level experience of the Christian faith, because Star Wars was more real to kids like us, than the Old Testament (at least most of the NT folks had been photographed and copied...)

But upon returning I considered how this is a way of life for millions-billions, great intellects, vast civilizations, isn't there more than fairy tales? And it really took dedication and concentrated effort and perseverance just to open up to those possibilities of a spiritual realm. But once you grasp that there's something to it all, and a breadth and depth that's unfathomable, and things might get rocky or difficult, decision point time: follow him to the Cross, or turn away and you'll never know?

Moreover, it became apparent but surprising to me that my reality was unlike others' reality, and I simply have no way of being inside the other's experience of their reality. There's no film or video game or book that can convey to you how people really live, love, and die. We just set out on life's journey and hack through the jungle, making friends along the way.
Now that the guy is no longer actively litigating early stage startups that he Angel invested in, and the true origin stories of the iPhone are more widely known he has become mostly irrelevant.

If you want to “checkout” some previous commit, jj has your back in three ways

- first, that commit that’s been merged to main is marked as immutable and, unless you add a flag to say “I know this is immutable and I want to mutate it anyway”, you can’t mutate it

- second, as part of your regular workflow, you haven’t actually checked out that historical commit. You created a new, empty commit when you “checked it out” using “jj new old_commit”

- third, you can use jj undo. Or, you can use “jj obs log” to see how a change has evolved over time (read: undo your mass find+replace by reverting to a previous state)
Yeah, that was weird, I never knew that. My dad was a fan of pinball, we had a jukebox and two different pinball machines in our house in the late 70s/early 80s. Even had a full size Pac Man arcade game for a few months, on loan from a guy he knew who repaired various coin-operated machines.

They’re far faster than a stovetop most of the time, have auto shutoff so you can wander away for a minute or two or not pay attention to it and not boil off a lot of water, etc.

Many parts of the world, it’s a good idea to boil water before using it for drinking, brushing teeth, etc.

So it’s actually really convenient for many use cases besides tea or coffee.
I'm really eager to see what happens in the near future with WAT & WASI, but I'm also very aware of seeing a repeat of DLL hell.

There are a few niches where standardization of interfaces and discoverability will be extremely valuable in terms of interoperability and reducing the development effort to bring-up products that deeply integrate with many things, where currently each team has to re-invent the wheel again for every end-user product they integrate with, with the more ideal alternative being that each product provides their own implementations of the standard interfaces that are plugged into interfaces.

But, the reason I'm still on the fence is that I think there's more value in the UNIX style 'discrete commands' model, whether it's WASM or RISC-V I don't think anybody cares, but it's much more about self-describing interfaces with discoverability that can be glued together using whatever tools you have at your disposal.

The air handling is exactly the same between the various 737 versions. The difference is that the engines are different. The CFM Leap is designed to shear the bolts on the fan if it goes sufficiently unbalanced, and incidentally the shock of this causes an oil leak. The A320neo will have a very similar problem of filling the plane with smoke if the LRD shears the fan bolts. It just does the air handling slightly differently, so it fills with smoke slower, and the entire cabin, rather than the flight deck first (if it’s the left engine that fails).
