It’s not a silly point. It’s clarifying a misconception that was long used as an argument for using CDNs to deliver script assets like jQuery, which was being repeated here in context.
> Finally, Google Maps seems more intent today on showing bars, restaurants, ads, and work-from-home businesses than useful map-related features. Sometimes it doesn’t even show the most basic information anymore, including street names.

I suspect they arrived at this through a series of A-B tests, since the more useful navigational information they display, the easier it is for the user to "learn" a city, and be able to navigate by themselves. So hiding information that allows the user to learn the map layout probably increases usage metrics.

A couple of years ago I noticed I missed precisely that: "learning" the layout of a city when I travel. So I started using Organic Maps, which always shows street names and other useful information to assist me in my navigation, instead of guiding me turn by turn.

Search results are a lot worse than Google Maps, and the routes it picks are also often worse, and it's missing traffic information. But when I'm travelling I'm usually on foot, and I'm there to get lost and discover the place, so it's OK if my route is not as efficient as it could be.
I think Maslow's Hierarchy of Needs is good place to get inspiration for this. It's guided my last two job roles in agritech and biotech. But I'm becoming aware that there seems to be an (inverse) correlation between how much money/funding is available as you go down the triangle.
He is an unseriousness person on twitter for sure. If you as a person take anything Musk says on twitter seriously you have greater problems. You shouldn't take anything on twitter seriously in fact.

It's almost like the people who dislike him most are taking him the most serious. It's funny actually.
I hope to follow when I purchase my next car here in Ohio. There's a new brand -- "Fisker" -- that's coming out with seriously reasonably priced electric vehicles. I'm going to be watching them closely.

Exciting stuff! I don't drive a ton ( ~1500 miles / yr tops ) so my emissions output isn't huge, but I think it will feel good to curb even my small driver's footprint.

I hope we look back on this time for vehicles fondly. I think we're coming up on the inflection point fast :)

It'll be a little melancholy for me as I like hot rodding. But I've already said that the moment they come out with an electric conversion kit, I'll have my car done right away. To hell with it, it'd be an awesome conversation piece.
The silliest thing I built was a hot-tub water heater system for one of those inflatable Intex hot tubs. Running the heat off 1500W was stupidly inefficient, so I went out and acquired one of those tankless propane-powered hot water heaters and rigged it to a commercial RV water pump and a 20# propane tank to circulate water into the hot tub that way. It heated the tub up from ~50* faucet to 104* hot in about 3 hours, instead of closer to 30 on 120V power.

The other thing I built is more of a lifehack living with sleep apnea. My CPAP's humidifier failed, and instead of replacing it with another proprietary humidifier, I bought an external CPAP humidifier[1] and then realized I could, with some clever plumbing, rig up a water pump from an external gallon jug of water to automatically re-fill my humidifier in the morning at the push (and hold) of a button. I took an oxygen-insertion tee, 12v pump, and some tubing and a check valve and attached the pump to the oxygen line on one of the inlets of the humidifier chamber. When you push the button, water flows through, through the check valve, and immediately down into the chamber.

Here's a snapshot of an early test: https://i.imgur.com/vund22E.png

It's been tweaked a little bit since then but it's my FAVORITE thing on my nightstand now. (And yes - that is a recalled DreamStation 1 - I personally opened it and repaired the defect foam myself. I don't trust the replacement device they sent me any farther than harvesting the motor from it when my old machine fails.)

Ask HN: Simple emergency phone for younger kids
I'm looking for a fairly simple phone for my 7 year old to use in emergencies as he's gotten to the age of being allowed to explore the greater neighborhood on his own. Any recommendations for something simple and no frills? I was thinking maybe a LTE connected watch but wasn't sure if that would be more difficult to navigate.

We (his parents) are on apple devices so figured maybe an older SE model but if there's a good Android option that's fine too.

I figured for connectivity I would just stick with something pre-paid since he won't be using it often.

Thanks!
Berlin from about 1995 to 2015 would probably have been that place. Closest thing today might be Marfa, Texas, which obviously is more of a town than a city.
We call them AUKUS fries now
All before 1982:

a belt-driven windmill to an auto alternator, complete with a household DC circuit providing switchable lights. (thanks Popular Mechanic magazine!)

a 6' multi-stage magnetic-driven projectile launcher complete with a horkage of old TV capacitors.

An amplified passive Ultrasonic sniffer with earphone.

An alarm trip sensor comprised of mirrored lightbeams.

And created/deployed "THE" original credit card reader for a set of gas pumps, later sold to Gasboy, Inc.

Then got wisked away for many other things for a long time.

Now, I am back to experimenting on a portable unidirectional EMP phase.

Companies should not be allowed to own other companies.
Actually the teams that would implement those fixes are not really in California (rather Seattle, Sydney, Tokyo, among others), but the problem is more the diffusion of responsibility and lack of ownership. Teams all have different metrics they're trying to drive or features they're focused on, but no one is responsible for the overall quality and user experience of "Google Maps" as a whole.

All of the things you mentioned have internal bugs, pitch decks, or maybe even patches pushed by individuals or whole teams. Likely even directors or VPs agree. But the organizational friction is massive and it's very hard to ship anything unless it's crystal clear that it is going to directly move a metric that is a focus for this year. And even then, if launching this feature touches multiple divisions, it still might not happen just because of the massive coordination effort.

That said, the green coloring was probably fixed in 2020. Transit has had a lot of work in the past five years, so maybe a chance London overground rail is fixed? The transit line rendering is still terrible, so you should probably use Apple Maps for that—theirs is beautiful.
It wasn't discovered in 99. That's when two of the researchers were in university and had a professor who had a theory that something like it could work. They took a good amount of time off from it while they worked at other jobs, before starting at their research center.

The way that technique is currently used, it takes bazillions of sample points from carefully-orchestrated survey flights, and it's looking for megastructures, walls and roads and things many orders of magnitude larger than the individual trees. It's not going to help you find a single vehicle since that could be a single fallen tree, etc, there's a lot of noise in the signal.

The worlds is full of problems, no shortages there, the evolution engine is still churning.

however, the problems occur with what is meant by "big" [more quantitative, utilizing science + engineering] or "important" [more qualitative, utilizing humanities].

without a common framework of tools, standards and ways it's hard-to-impossible to agree on the existence of 'the problem' and/or how 'big/important' it is.
I bought a house that was sold as "uninhabitable" in Amsterdam, pulled out all the interior walls, applied insulation, then taught my self plumbing and did the plumbing, redid the wiring, installed the gas heater, laid radiant heating. I built new interior walls and did all the interior finishing except for plastering downstairs and pouring cement over the radiant heating, which I had professionals do. Coolest single thing I built in the house is probably the kitchen peninsula which I somehow aced the oak waterfall on (thanks to Festool I guess).

Sounds kind of cool listed out like that but it was a shit ton of work, it's still not fully done and as I was an absolute beginner with limited time a lot of things are half-assed or have to be redone at some point. I quit my job shortly after buying the house (for unrelated reasons) and took a year long sabbatical but it still wasn't long enough enough time. People warning you about renovations like this should be taken seriously.

If instead of buying this house cheap and doing this renovation, I probably could've just taken a job at a bank or some big tech co in Amsterdam and afforded the same or even nicer a year or two later. Though, with the housing market being as it is the timing was super favourable for me financially. It's also kind of neat to live in a turn of the century house with all sorts of modern amenities like radiant heating, thick insulation and HRE balanced ventilation.
IMO the #1 biggest most important problem is the design of institutions.

Specifically we need to design institutions that can accept higher information throughput from their members. This applies to corporations, governments, academia, etc.

When I say information throughput, I mean, accept information from its members and change its own behavior in accordance. Our current institutions were designed when people had to travel days to go contribute to law writing etc. That's no longer the case. The amount of information going to and from our institutions is much larger, but the institutions themselves have not scaled. Institutional processes can be very similar if not equivalent to software. And there are a lot of preventable problems just from scaling.

For instance look at our red/blue culture wars and how obviously it corresponds to population density... maybe we need to have variation in policy based on population density. Instead whoever is in power pushes their policies on everyone. When a republican is in, the cities suffer, when a democrat is in, the countryside suffers.

We also have corporations making decisions that would not be made if the shareholders and employees were given all the information and polled for the best decision.

We have policies that are made "for the greater good" that don't compensate those who lose out. This makes them unpopular. Any policy that is against fossil fuels should also focus on providing compensation to the millions of people who depend on it for their livelihood.

We have insane amounts of waste in the government and 20% of people think their jobs that they're forced to work are meaningless.

The fact that there are some readily identifiable, strong patterns for some of them indicates that there could be a relatively straightforward cause. IMO these problems aren't impossible to solve. They just need a systematic approach.
They need to be studied in academia like we study physics. Imagine if we spent the amount of money we do on particle accelerators to instead create a few dozen "test cities" where people can move there and experiment with different economic and social systems.

Until then, though there's still a whole lot of theoretical work that can be done understanding how information flows through an institution and ultimately affects and constrains its behavior

Sadly there is no conspiracy needed. The for profit health care model is a significant contributor.

Dentists are also business people, and there are strong monetary incentives for them to upsell.

That's not to defend the behavior, but I think we should acknowledge the problem is systemic and that a non profit healthcare approach would be more appropriate for the vast majority of situations.
I think it's more complicated. You'll find lots of really organized and popular hate groups in telegram channels, on tor and other places where there is no real advertisement model.

Since my ADHD didn't allow me to read this long article, I deferred to Claude.ai to summerize it and allow me to understand all the comments... Here's it is,rewritten in a summerized

For 5 grueling years, the author worked long overnight shifts at a massage parlor in Toronto's industrial area. The 2pm to 2am days brought unpredictable clients and income, requiring emotional and physical intimacy when exhaustion left little to give. Yet amid the job's difficulties, the author found beauty in the simplicity of people's fundamental needs late at night—food, sex, shelter. Stripped of pretense, their raw desires connected them in basic human instinct and experience.

A sense of community existed among fellow night workers—at the parlour, driving cabs, serving food. Brief moments conveyed camaraderie: a knowing glance, an extra pastry. The author sorely missed this unspoken bond after leaving for corporate office work. The professional world felt disconnected compared to the pack she once travelled with.

The overnight world is dismissed as "low skill," but takes great skill to handle unpredictability and confrontations with grace when exhausted. The author developed deep respect for those keeping cities running 24/7 through their undervalued labor.

Though difficult, the ephemeral moments of care and understanding within that transient world meant something real. Like the taxi driver gently ensuring her safe passage home in a snowstorm. The coffee shop server passing extra sugar despite her unconventional attire.

Years later, the author still reflects fondly on the stories and bonds built while working nights. The brief connections and wordless care showed her a beautiful side of humanity she hasn't experienced since.

Do you have an example or two of a country with no patent protections that still invests in research? If no incentives, there are no outcomes.
How to get good at shitty work
That depends a bit on the definition I guess - let me explain why:

If you call a method in e.g. Java which is annotated to return a string, then by definition you have to expect the following possible outcomes:

- The method returns a string

- The method throws an exception (or rather: a Throwable)

- The method does not return at all

That's just how it is in Java and also in most other languages. Therefore, throwing an exception must always be expected. Only if there were only checked exceptions and no unchecked exceptions this would be different - but then how do you handle things like Stackoverflow or OOM exceptions?

In fact, if a methods says it returns a string, what that really means is that that it will not return something else than a string. That is the real meaning. It cannot e.g. return an integer. But that's about all the guarantees that it gives.

So you see, it's tricky.

There are however languages where you can really rely on that they do return what they claim. But those languages then force you to prove that a method actually returns within a finite amount of time and such things. Not very practical to use in many cases.

I mean no not at all - patents are legal tools that can be skirted around just like anything else.

If people don't respect the patent and produce things with it, your recourses are lawsuits - patents aren't stopping chinese manufacturers from exploiting patents from the US.

And for something this important, I can even imagine governement making some kind of "public good" patent for things that are too influential - where the compensation is pre arranged and reasonable.

Six Declines of Modern Youth (Kurt Hahn, 1886 – 1974)
I recently became aware of Kurt Hahn whilst watching a documentary on Prince Phillip [1]. Hahn was Prince Phillip's headmaster/mentor, and founder of the boarding school attended by the Prince.

I'm not sure if Hahn published these points all at once, or if they were collected over his life. Either way, they seem extremely relevant to modern times.

> 1. Decline of Fitness due to modern methods of locomotion;

> 2. Decline of Initiative and Enterprise due to the widespread disease of spectatoritis (i.e. "excessive indulgence in forms of amusement in which one is a passive spectator rather than an active participant");

> 3. Decline of Memory and Imagination due to the confused restlessness of modern life;

> 4. Decline of Skill and Care due to the weakened tradition of craftsmanship;

> 5. Decline of Self-discipline due to the ever-present availability of stimulants and tranquillisers;

> 6. Decline of Compassion due to the unseemly haste with which modern life is conducted or, as William Temple called it, "spiritual death".

I can relate to just about all of these, either personally, or having read modern examples during bouts of spectatoritis.

Fortunately Hahn proposes 4 solutions. I'm interested to get your thoughts on these.

> 1. Fitness Training (e.g., to compete with oneself in physical fitness; in so doing, train the discipline and determination of the mind through the body);

> 2. Expeditions (e.g., via sea or land, to engage in long, challenging endurance tasks);

> 3. Projects (e.g., involving crafts and manual skills);

> 4. Rescue Service (e.g., surf lifesaving, fire fighting, first aid).

Intel is suffering financially. This is the phase in which they, regretfully, cross all ethical boundaries for the sake of the company's bottom line.
> Workers aren’t “true threads” they’re isolates. True threads share state. True threads in fact fight over shared state, which is the problem.

I see no inherent fighting over shared state in Rust yet it clearly supports threads. "True threads" don't "fight" over shared state; they transfer ownership, whether that be through a borrow checker or with a mutex. The "fight" generally occurs when you get ownership wrong, such as in C++ or Java.

It's a distinction without a difference to identify them as isolates. Do you have as much flexibility with JS as with other languages that support parallelism? Of course not; that wasn't the design goal and usability tradeoff for JS. However, transferring ownership of shared state between two or more actively running execution environments within the same process (which is what Workers do in JS) is what most folks would describe as threads. Isolates are in fact a subset of… threads.

All isolates are threads but not all threads are isolates.

>In the current system scientists allocate reproduction efforts to results that they intend to build on. So if you’ve claimed a breakthrough technique for levitating widgets — and I think this widget technique can be used to build spacecraft (or if I think your technique is wrong) — then I will allocate precious time and resources to reproducing your work.

Wouldn't this imply that worthwile results are already being replicated, so the primary cost has been paid and we just need to give some method to disseminate this work and then have it factor into the credibility of science? pre-print < peer reviewed < peer replicated, with the last step having internal rankings depending upon how much it has been replicated?

And it'll also show when someone is building on things but not replicating it, which I guess is an issue in some fields more than others.
It was probably hard to predict at the time, but floats larger than 64 bits never really took off. Turns out that hardware vendors didn't want to spend that many transistors, the x87 stack machine was a disaster, and software settled on the lowest common denominator, which was double. It's ironic that Intel was at the forefront of the floating point specification of the time, as X87 royally screwed up floating point for generations. It is was like pulling teeth to get the thing to do 64-bit math. Thank god x86 gradually moved to SSE, though it only took 25+ years to correct that fiasco.
