Everyone gets to feel their own feelings, but there's just so much that doesn't resonate with me here...

> I can’t use my Bluetooth earbuds while they’re charging.

Many bluetooth headphones have battery life measuring in tens of hours. And every set I've used, long life or otherwise, recharge to 80% in a handful of minutes. I agree that an airpod's miniscule battery life is appalling, but you can stand to pull them out of your ears for five minutes every four hours, and you can charge them one at a time so you never need to stop listening, and my Bose QC35IIs still get more than an entire day of playtime after multiple years of recharge cycles.

> In a critical-care facility, it’s hard enough to find one free mains socket to connect a charger to, let alone two.

I haven't used a single-port USB charger in a decade. All of my chargers have multiple ports on them. GaN tech makes them very compact even at high power output.

> Sound quality is better.

Maybe in the abstract, but for most people this isn't meaningfully true in any way that actually matters to them. And if you're listening to "comedy shows and audiobooks" it definitely doesn't matter. Speech has an extremely limited useful frequency range, and those tracks are typically extremely compressed without any ill effect.

> The headphone jack is a “just works” kind of technology...

Nothing is ever fully a "just works" kind of technology. Things only just work until they stop working. The 3.5mm jack wore out after a year or so on every device I've ever owned that experienced plug/unplug cycles a few times per day because of accumulated minuscule amounts of force over time. This is more likely for devices like phones which are ultracompact and go in your pocket. Google for variations of "3.5mm port broken" or "loose audio jack" some time and you'll see that this is a common problem. The wires themselves also wear out from repeated flexing over time, even with strain relief. I had a pair of Shure E2c years ago that stopped working if I didn't hold a bend in the non-replaceable cable at a particular spot with a rubber band.

> Ordinary wired earbuds can be small enough to wear whilst sleeping. I’ve never seen Bluetooth earbuds that are.

Then you didn't really look IMO. Bluetooth headsets for sleeping is a whole cottage industry now. Anecdotally, I personally sleep fine in honking large Bose QC35 IIs, but that obviously depends on sleep position.
Considering how common some version of this story is, and based on my own experiences as a patient, I'm convinced that most doctors lack a functional understanding of conditional probability. They seem to think that if the prevalence of a disease in the general population (or a specific patient's age/sex/racial demographic) is low, then the probability of someone presenting with signs and symptoms of the disease having it is also low, even if there's no better explanation.

If you're going to criticise the Brazilian judiciary, or anyone else for that matter, it's much more effective if you do so with something they're actually doing. Who said anything about defending it?

I doubt many people even thought about it. For them, bluetooth was available. Now it is almost the only option.

Quick and Dirty Linear Algebra for Programmers
I only skimmed the article. Is the high 'collar' shown here supposed to be a realistic replica?:

It looks much higher than a medieval bevor and very impractical. You wouldn't be able to see much of attacks to your torso or legs.
>You know it’s bad when public health officials are like: “hmm, the kids aren’t having sex, drinking, doing drugs (except vaping), or commuting vandelism/violence - but their mental health has cratered and they just sit at home playing fortnight or watching cat videos.

Well most of those things are expensive. Bedrotting to cat videos is free.
Smoking has always been an issue.
I'm working on a book to introduce developers to the nitty gritty of language models, and realized that there is a base level understanding of linear algebra required for me to explain things properly.
This is an attempt at providing that core level of understanding.
I'm very interested in feedback, particularly from people without much linear algebra experience.

Thanks!
The camel's nose under the tent.
Code is a special kind of data, i.e. the kind of data that can be the input of an interpreter or compiler.

A LISP program is not (arbitrary) data, i.e. it does not contain arbitrary lists. Giving data, i.e. an arbitrary list to any LISP interpreter or compiler will just result in an error message and a translation failure.

A LISP program contains only invocations of functions or macros (besides special forms) and each invocation has an associated list of arguments. While the classic LISP convention is to write the function/macro name after the opening parenthesis, this notation is equivalent with writing first the name of the function/macro followed by a list of arguments enclosed in parentheses.

Conceptually, data in LISP, which consists of lists of values, should have used a different kind of brackets for delimiting a list.

Because of the limitations of the character sets available in old computers, the round parentheses have a dual role in LISP, as delimiters for lists that are data and as delimiters for the lists of arguments used by function/macro invocations. The two roles are differentiated by the use of the QUOTE special form, which is just a workaround for not using two different kinds of brackets, which would more clearly differentiate LISP data and LISP code.

If all the LISP functions or macros had a fixed number of arguments, then the LISP code, i.e. the invocations of functions or macros, could have been written without parentheses. In that case, the LISP data, i.e. lists, could have been delimited by round parentheses without using the QUOTE special form, which would not have been necessary.
PyPy is great for loopy/branchy code with lots of function calls. Things that you haven’t done the mental gymnastics to vectorize. That being said, in my line of work, when Python is the bottleneck, a little bit of numpy goes a long way, especially if you orient your axes around the reductions you have planned.

The other thing I’ll say for pypy is that by demonstrating that a Python interpreter written in Python can be faster than Python, it’s pushed CPython to improve performance as well. Not that CPython developers wouldn’t pursue performance gains on their own, but pypy offers a specific target, and we’ve all benefited from the comparison.
Given that most of their AI hardware was bought for better feed ranking, probably not unless you reduce the entire company to nothing but "serving ads".

This had a post on HN before and I didn't find the arguments terrible compelling. I'm curious what security advantages they might be able to say exist though.
Eventually they’re going to catch up with the state of the art, then their progress will stall.
The best part are the follow-up emails of people trying to cover their ass and pass the buck within the giant corporation. I'm sure all those emails and the time it took to read and respond to all of them, and all the meetings about them that we don't see, really helped the world. /s
Ask HN: Any spell-checkers that are good?
Given the vast strides made in language modeling in the past years,
why are spell-checkers still so bad? Linux spell-checkers are based on
dictionary lookups and Levenshtein distance and are terrible. E.g.,
they think "Levenshtein" and "lookups" in the previous sentence is
spelling errors when it isn't. And detecting the grammatical errors in
the previous sentence is too difficult for them. The year is 2024, why
can't any spell-checkers figure out that "Were where you last night?"
is incorrect?
> Now, any time I find something new it always has a polished marketed feel to it and has none of the secretive clandestine undiscovered power that old tech had.

If you're getting old, then I must be too, because I know your pain. I don't remember the last time I saw new tech(1) that felt like a real novelty to me.

Now that I've been fully in "career mode" for a few years, I have the budget to engage in my hobbies with greater depth than ever before, and that's amazing. Yet, I've found myself going deeper and deeper into the "retro." Old computers, old cameras, old music formats, etc. It's easier to find novelty there.

(1): this is limited to tech. There's great new music that isn't too hard to come by if you can manage to train Spotify's algorithm to give it to you.

Not really different from fiat at all. If you give someone your password to authorize wire transfers, you're going to have the exact same problem as with crypto. Only if they stole the password then you might have a chance to apply for insurance claim.

And unlike crypto, with fiat there is no way to have stuff like multi-signature wallets or smart contracts than only execute if the conditions are met, and safely. If you wire your money to a forex exchange that's actually a scam, you're probably never going to get the money back. If you use a decentralized crypto exchange based on smart contracts, there's no chance of a problem - or everybody relying on cryptography has a big problem.

And of course, there's no way to have fiat money in a hardware wallet. You can have your bank token there but that's really not the same thing. A hardware wallet like Trezor will actually successfully protect your crypto, unlike a fiat bank with a nice MFA token - that just makes it harder to impersonate you, but it can't protect you from the bank itself.

Overall, don't blame "crypto" for something that's happening on a daily basis with fiat too - scam forex/option trading exchanges were a thing much before Bitcoin. Cryptocurrencies are an improvement in this case because while not everybody makes use of the security possibilities, at least they exist and it's not hard to use them.
Is Affirmation Culture Sabotaging Our Friendships and Ourselves?
Lots of older companies still do. When I worked for Sherwin Williams a couple years ago, every aspect of the business was run by some DOS style software on some custom nix OS.

Once you spent a little time to memorize the hotkeys, you can do things incredibly* fast. No action is ever more than three or four keystrokes away. Menus and actions appear in ordered lists and never change. If an item is removed, its menu entry is simply blank until something else gets added five years later. Everything is always exactly where it's been since 1980.

People want to talk about clean and minimal interfaces, but that art peaked in the 90s. There is not any traditional GUI application anywhere on the market that can compete with the sheer speed and productivity of a DOS application that's been progressively optimized over half a century.
I'm in this fun loop right now where I have an undiagnosed small mass. Everyone agrees the best way to diagnose it would be with an MRI, but no one knows which kind of specialist to have order the MRI or what kind of MRI to order...because we don't know what kind of mass it is. We know it's near a few things, like my lungs and my spine, but it's apparently not connected to them ("apparently" in reference to the cardiac MRI that picked it up incidentally). Everyone who has seen it (original MRI reader, cardiologist) is defaulting to "PCP should order," but PCP doesn't know what to order.

Meanwhile I'm sitting here saying it's asymptomatic, very small, "nonaggressive," "well-circumscribed," and incidentally discovered. Can't we just ignore it? We'd never have known about it but for this unrelated test.

But no. Everyone agrees we oughtn't do that. They just don't know what we ought to do instead.

The system is hard enough to navigate when you're brighter than average and generally well. I have no idea how they expect people to do it when they're ill and have no idea how to read medical research.

ETA: I'm only in this situation subsequent to my sister's idiopathic sudden cardiac death. Medical examiner's report recommended any siblings or offspring be screened for heritable cardiac channelopathies. She had been called a hypochondriac from the time she was 12 until she died suddenly at 29 and surprised the heck out of everybody.

tl;dr zinc does not affect or prevent the common cold.
The current Celstron is owned by a Taiwanese company and just acts as a US distributor for that company so I wouldn't say its the same company anymore.
When you look at these long-lasting companies, they are all slow-burning concepts with very little competition and little innovation, so you're not going to find suggestions of "technology" companies on this list. The innovator's dilemma cannot be an issue if you want your company lasting hundreds of years. Another problem here is that you need to financialize as little as possible, so you can't have a lot of competition. Investors don't have 500-year time horizons, so those are out (especially VCs). Debt on physical assets seems to be okay when used sparingly.

1. Datacenters or datacenter construction may be the most high-tech ones I would try. Not cloud services, but the literal physical buildings.

2. Musical instruments, art supplies, or other cultural/religious goods of some kind, possibly as high-tech as electric guitars or synthesizers (although those have not historically gone well).

3. Financialization businesses like insurance or securities packaging of some kind could work (if you don't get high on your own supply).

4. Food and hospitality never go out of style.

I assume that the way this sort of business would work is a 3-step process:

1. Start by becoming the best in the world at something very weird and specific.

2. Bootstrap your business with enough connections to start making sales without needing significant financing. Run as a completely bootstrapped business.

3. Convince your children to continue being the best in the world at that thing and maintain your values. If you don't have any suitable children, adopt one. Also, make sure to disinherit any children who are not both very competent and fully onboard with the plan - you need to keep the power concentrated in the one or two best successors.

It's no accident that a lot of these long-lived businesses in Japan, where all three of these are part of the culture.
I wonder how many of these were considered semi benevolent either during their entire life span or lucky or wise enough to do so during times of turmoil.

Some stores will have people willing to stick their neck out to defend them during riots. Some have good insurance and don’t care. Which ones get obliterated when the pitchforks and torches come out?
Three seconds? A purpose built trail cam is considered slow if it takes 0.7 seconds to boot up and take a picture.

I meant 2019 but admittedly I only know of the Polish market and choices most "normal" (statistically) people make - which is to study the thing at the university without getting any job experience in the meantime.
Here bootcamps were something maybe 1-2% of people did.

So if you started in 2019 you'd be graduating right into the "layoff" market in which juniors have virtually no possibility to get hired.

I avoided phones without a headphone jack for a while for similar reasons. I didn't want to use a dongle or buy new wired headphones, and I didn't want to use a 1-to-2 USB-C/lightning dongle to listen to music and charge at the same time.

Then I invested on a Sony WH-1000XM3 and suddenly battery life wasn't a problem anymore. That was a big change from the cheap bluetooth earphones I had used until that point, which had terrible battery life. I could use them for a full day, maybe forget to charge them, and it never ran out of battery. So I stopped using wired headphones.

The downside was the price... the WH-1000XM3 wasn't cheap, but things have changed. Last year I wanted something smaller, so I bough the Anker Liberty 4 NC. Much cheaper, good noise cancelling, good enough sound quality, and from time to time use them for 8 hours straight (AAC mode) without putting them in the case. The earphones + case can last a week without charging them (with my usage of course). It wouldn't be a problem even if I was in hospital for a while, like in OP's case.

So I'd say that the list of downsides is getting shorter as good bluetooth headphones get cheaper. It's still more expensive, but it's a different world compared to 5 years ago.

If you still want to use wired headphones, then yeah, nothing has changed and losing the headphone jack is bad. But if you're willing to try wireless, then it's not as bad as it used to be.
Not sure what you mean by decimal points. Did you mean the number of decimal digits to be printed in total, or the number of digits after the decimal dot, or something else?

In any case, what Dragonbox and other modern floating-point formatting algorithms do is already roughly what you describe: they compute the integer consisting of digits to be printed, and then print those digits, except:

- Dragonbox and some of other algorithms have totally different requirements than `printf`. The user does not request the precision, rather the algorithm determines the number of digits to print. So `1.2` is printed as `1.2` and `1.199999999999` is printed as `1.199999999999`. You can read about the exact requirements in the Readme page of Dragonbox.

- The core of modern floating-point formatting algorithms is on how to compute the needed multiplication by a power of 10 without needing to do it by the plain bignum arithmetic (which is incredibly slow). Note that a `float` (assuming it's IEEE-754 binary32) instance can be as large as 2^100 or as small as 2^-100. It's nontrivial to deal with these numbers without incorporating bignum arithmetic, and even if you just give up avoiding it, bignum arithmetic itself is quite nontrivial in terms of the code size it requires.
nostr's protocol is also fairly unstructured compared to atproto. ive researched bluesky, farcaster, and nostr, and their cultural origins have definitely impacted how they have approached their designs.

There is no predicting what approaches will win, but those 3 are the current viable options I think.

FYI I am part of the crypto crowd myself, but I am a SWE looking at these systems, not a CT gambler, lol.

Nope, not true in my book. I would not like to be in any company that "selects"
a small group of elites to a hawaii or las-vegas "retreat". then, said elites would propagate their new-found retreat wisdom from their cult-leader down to the plebs.
