> I do not fault the particular pump that we bought or our installers who were careful and professional.

I feel like the author may be letting the installers off too easily here. It seems like there are two main possibilities: either no one understands how heat pumps actually work in the real world and none of them meet their claimed efficiencies (possible, but in my estimation not that likely) or the heat pumps he has installed are unsuited for their purpose (or badly installed). I'm inclined to suspect that he was sold the wrong heat pumps.

Confirming this suspicion, in an earlier post (https://willbrownsberger.com/our-heat-pump-experience/#comme...) he gives the specs for his heat pumps. I don't know this particular model, but a commenter after him claims they are not the sort of "Cold Climate Heat Pumps" that would be appropriate for Massachusetts. Since this matches the symptoms (adequate heat production but low efficiency) I'm guessing this is the real issue here.

I think heat pumps are a great technology, but worry there is going to be a backlash against them unless we can rein in the hype. And something is has gone really wrong if local installers can't be trusted to install a heat pump that is appropriate for the climate they are being installed in. Maybe the best thing he can do as a Massachusetts state senator is to enact more stringent laws preventing the installation of non-cold-climate heat pumps in Massachusetts so others don't suffer the disappointment that he did!

> The bottom line is, just because somebody says their algorithm does a thing, doesn't mean that everyone has to accept it immediately, and without critical discussion.

That critical discussion was 10 years ago. Embeddings are vector representations of meaning. They’re not perfect, but they can be used for enough meaning-dependent tasks that this statement shouldn’t be controversial.

All this AI/ML stuff is so exhausting because the philosophers come out of the woodwork. They don’t prove anything or disprove anything, they just kinda whine.

When I was a flight instructor and said the airplane wanted to float down the runway, no one tried to point out that airplanes don’t have desires. I can say a server knows another server is offline and that’s fine too. But say “reason”, “think”, or “meaning” with something AI related and it’s like all work has to stop until we stop using that precious word.

I’ve tried to engage with that stuff less, but got tricked cause I thought this person just literally didn’t understand.
A friend lived in a smaller town where mail was processed in the nearest larger city (in a neighboring state). But, if you needed something sent to (most of) the rest of the state, it was faster to have it processed in a different city in the other direction. They had a specific drop box for that, which cut delivery from two days to one. I, living in the second city, was stuck with having my mail routed out of state to get to him.
A CBC is a specific and very common lab test and does not include a ferritin level. It’s a separate test.
When I lived in Switzerland, some clever people thought about that, as it used to have lower taxes for electronics.

It so happens that there are databases used by the customs agents that can trace back serial numbers to countries and purchase locations.

Not the same. 1080 would be unbearable compared to a MacBook pro screen at 14” (3024x1964).

Edit: the oled one has acceptable resolution. I don’t see any specs on the ssd though so it may be SATA junk. The problem with other manufacturers is that they aggressively skimp in all the places people don’t look. Part of what you get for the Apple tax is some assurance that’s not happening.

Ask HN: Is there an online service which gives you a personal number for SMS?
This seems to be a heavily SEO-spammed topic, and most may be after easy access to countless of phone numbers for evil-related purposes.

I only need a private number for receiving SMS, no need for calling and sending messages. A monthly or yearly fee isn't a concern. The main purpose is to protect my own phone number from spam, unwanted promotion and data breaches. Local retailers commonly require a phone number when ordering online and some seem to only send parcel information there. Certain websites do demand a number when creating an account.

In the past I've bought prepaid plans (which expire after six months), but would prefer a streamlined approach. Preferably would support email notifications (and RSS) for arrived SMS.
As an avid Windows wizard who strongly dislikes Apple, I will give credit where credit is due: Apple's shit Just Fucking Works(tm).

Show HN: Game industry news with AI summaries and author scoring
I’ve always been a tiny bit frustrated over having to visit multiple websites to get my gaming news, and since my twitter followees have mostly abandoned the platform, my feed there isn’t working out for this either. Obviously, instead of just using an rss reader, I built a web app because it was kinda fun.

The site aggregates article links from a handful or so gaming websites and optionally allows people to up/down vote articles. This score goes towards the author of the article though, not the story itself. I’m thinking if this gets any traction maybe there’s a semi-interesting “author quality” metric that might appear from this.

I also run the content through an AI model to extract a summary, which turned out surprisingly better than I expected.

Yup, just like they did for Photoshop and Premiere, After Effects, etc. Honestly, I want this to succeed. I want a blender-based Substance Painter alternative. I'm not too keen on it being just like Substance Painter but I should be able to achieve the same results. If you buy SP on steam, I'm pretty sure valve will make sure you keep that version forever with their vast cdn. Whether Adobe adds CC features to lock you out is almost a guarantee.
There's a sales tax in the US too. 7.25% in CA, on top of the product price.
The term "personal computer" predates the IBM PC by a few years, and was generally a synonym with "home computer" (which Apple computers also were.)

For instance, the TRS-80 was not an "IBM compatible PC", but was advertised as a personal computer. When these terms were new, they weren't yet technical jargon with subtle meanings. "Personal computer" meant simply a computer intended for personal use.

Seems fair. If a manually driven car were to block a streetcar like that surely that would result in a fine? This shouldn't require any sort of special treatment for self driving cars one way or the other.
Yet somehow using it was far more pleasurable than Pocket PC. I could certainly do more things with my beastly 640x480 624mhz ipaq, but everything about the UX was better on Palm. Apps saved state automatically. I didn't have to open a start menu to launch something and I didn't have to open two menus and manually close them because Windows Mobile doesn't close anything when you hit the X button. The buttons, d-pads, and styli all felt better, and the screen didn't waste 20% of its real estate with two giant useless buttons across the bottom of every app.

Indeed, it fails if you invoke UB. For example, an int overflow in a constexpr causes a compile error:

<source>:5:17: error: static assertion expression is not an integral constant expression
static_assert(1024*1024*1024*3 != 0, "UB");

I quite like the keyboard, but then again I'm not very picky with keyboards. I got mine reshipped from Germany, so that's a route you can go.

If you want a repairable laptop with a good keyboard, getting a Framework now gets you much closer than hoping someone makes one. Also, you enable and encourage the company that already makes a repairable laptop to eventually sell a great keyboard, which giving your money to Apple or Dell doesn't do.
Karl Marx said capitalists gain profit by expropriating the wealth a worker creates during surplus labor time. There is a conflict in the relation of production between the worker creating the wealth and the heir seeking to expropriate it.

Feudal pre-capitalist society did not need unemployment, but capitalist society does, if there is no reserve army of labor ( https://en.m.wikipedia.org/wiki/Reserve_army_of_labour ), the workers creating wealth have more leverage to keep more of the wealth they created.

This is all happening because the rentier class is seeking to retain its rate of profit.
interesting. What are you doing with the profile you create about me and my unique choices?
Per standard wording if an evaluation contains an undefined operation then it is not a constant expression. It means that undefined behavior should result in compilation failure if it happens in a context where a constant expression is required, like in static_assert.

However the standard only requires this for language-level undefined behavior. For undefined behavior happening in the standard library it's unspecified whether the expression is a constant expression or not. So no, constexpr tests don't cover all possible UB.

Also even if in theory language-level undefined behavior should be caught in constant expressions, in practice compilers miss a number of undefined behaviors. They are generally good at catching out-of-range indexing, using objects outside of their lifetime, using uninitialized values, signed integer overflow and modifying const objects. However there are a number of subtle undefined behaviors that they don't catch, like unsequenced operations on the same object, invalid values for unscoped enums.

There might be some overlap with runtime tests with -fsanitize=undefined,address. For catching uninitialized values at runtime though you probably need msan, which is a pain to set up, but constexpr tests cover that. On the other hand the function you test might not be available at compile-time.

Anyway, constexpr tests are a valuable tool. It's not a silver bullet.

I’m in the camp of: I like the colors and cuteness of the air (I’m a guy for what it’s worth) but I always buy the pro ‘cuz, we’ll it’s “pro”.

It’s probably more economical to buy the air at a lower cost and replace it more frequently but I dislike the hassle of moving files (the cloud has simplified this a lot), but more recently I’m concerned about e-waste.
> What's the cheapest wearable or device that can probably tell you if you have apnea?

Years ago I was once concerned I might have had sleep apnea. I did see a doctor, who said I almost certainly didn't have it. I also bought a $40 pulse oximeter that could do logging, and taped it to my finger over a couple nights. I didn't see my oxygen level drop below 90% (or something, I can't remember), so I figured I didn't have it.

My understanding is oxygen level is one of the most important factors to track for sleep apnea. I am also super-skeptical of movement-based sleep tracking. Since my impression is it's typically half-assing with cheap sensors that aren't very suited to the task (on their own).
> It protects those who reveal secrets the authorities would keep hidden, those who criticize the way things are done, and those who propose doing things in a different way.

Freedom of speech protects your right to say that the earth is round. The roundness of the earth won't reveal any corruption scandals, it won't lead to major political reforms. It's not political at all. And yet is is just as protected as anything else.

More generally, defining freedom of speech in terms of government is wrong, because freedom of speech fundamentally does not depend on government. It is an inalienable, God-given right, that people have even in a state of nature where no government exists.
How strange that the only way to get one of those devices is via the NHS. Usually if you have to wait too long, or something isn't available in the UK, there's a private medical service more than willing to take your money!
"…would provide weird incentives like frequent comments, or higher volume, could rank a person higher than if they had occasional comments further down the thread."

I know I'll be out of step with most who comment on HN but I question the necessity of having a ranking/voting system at all. All it seems to do is to act as an ego booter for commentators and it messes up orderly discussion when people insist on posting replies to the first commentator.

As a news aggregator, no doubt HN needs some method of ranking stories to set their listing lifetimes and their importance (page ranking) but that could be accomplished by the number of clicks a storey receives and or how long a visitor/commentator stays on a story (or the time between link clicks).

I also question aspects of the voting system as currently implemented. It's not unusual for me to receive down-votes on comments to controversial stores but not receive a comment from the down-voter. Why bother with this system if the voter hasn't the gumption to say why he/she disagrees with one's views? (One could discuss the psychology and social philosophy behind this but here is not the place).

Another annoyingly aspect of the voting system is the lack of stats. The time I take from posting to checking to see if someone has replied varies wildly—from minutes to days to never. This wide variation is significant when I post to controversial stores. Days later I can check back to see if there's been any votes or replies only to find there has been none.

At other times, I've monitored the incoming votes almost in realtime and watched them oscillate around 0 or 1, that is I've received many up and down votes but the long-term average is zero. Come back and check days later and one hasn't a clue from the stats if anyone at all has actually read one's comment let alone the fact that it was equally controversial to both sides of a polarized audience. HN should allow users access to these long-term stats.
Its subtle, but its definitely not neutral.

The issue is that the (extremely short and light on any meaningful discussion of the issue) article is presenting this situation from the perspective of the inconvenienced Billionaire and from the perspective of how much tax revenue is being lost.

This immediately frames progressive tax policies, in the readers mind, as having "bad" outcomes, since the outcomes for the Billionaire and the tax base are "bad". No government policy is going to have completely positive outcomes for all parties all of the time and cherry picking two "bad" outcomes is the problem.

Assuming for the moment that it should even continue to be legal for people to amass that level of wealth, the challenges the Billionaire class face should be the absolute lowest possible priority for public policy. The fact that it's the first talking point is the issue.

There are myriad ways this article could be written that don't focus on how "hard" these policies are for the Billionaire class and instead focus on how good they are for everyone else.

I doubt most addicts would have the means to buy high quality substances. And of those who had, some may still chose the cheaper street stuff. And this is where society often is asked to pick up the bill. With guaranteed payment out of tax dollars the pharmacy company producing the substitute now has an incentive to get people on it. The problem will never be solved but now it is even more expensive. This is a misallocation of tax money in my opinion.

Singapore doesn’t seem to have a huge drug problem, and they went all in on what you call “the war on drugs”. So maybe there is a winning strategy there, at least for Singapore?
Elsewhere he says that his heat pumps are two Daikin RJQ18TAVJUA:https://ashp.neep.org/#!/product/56878/7/25000///0.

Much of the other information is probably available elsewhere on his site: https://willbrownsberger.com/heat-pumps/

As I mention in another comment, I think the base of the problem is that the heat pumps he has installed are simply inappropriate for his climate.

Modern CPUs can do microsecond accurate timing just fine. You do need to design the software correctly, however, not just shove something into an RTOS thread.

In my own experience using spaced repetition for math: math has both semantic and procedural knowledge. The procedural knowledge comes from doing problems and rewriting proofs. But the semantic knowledge is also important, and you can acquire and retain this through spaced repetition.

I was going to write some rules specifically about math but I might write those as a separate post because they got too long. I think I've benefited specially from memorizing the proofs of theorems, though refactoring proofs into multiple lemmas to make each proof small enough to fit in a flashcard is a tedious process.

Exactly, the problem is that at extremes "classical" physics doesn't explain what we can observe.
That’s true, but that would be fairly trivial to do in a C program with only stack variables. Just always have only 1 mutable reference.

Something like C++ or Zig could enforce those rules even more easily.
