DIY medical testing is only a part of the DIY testing boom.

Just one small example is the amazing array of test strips we have for liquids: Pool test strips, drinking water test strips, urine test strips, blood test strips, drug (urine) test strips, pregnancy (urine) test strips, and much more.

Back during the COVID-19 pandemic, I set up 2 air particle checkers that returned the number of particles they found in each of (maybe 8) sizes. I put them in 2 clear tubes, and duct taped a COVID-19 mask between the tubes. A pair of fans moved air over the first checker, then through the mask, then through the second checker. I proved that below 2.5 microns, none of the COVID-19 masks people were wearing at work did anything. That was when I started laughing at the whole thing. This is the kind of tester I used: https://www.amazon.com/Digital-Quality-Detector-Tester-Monit... Checking if the testers read the same without a mask was a simple as taping the tubes together without a mask between them.

The electronic meters we have today is astounding. Digital meters that do not use test strips can measure dozens of gasses, from any explosive gas to O2, CO2, CO, LP (I know it's not a liquid when it's a gas, but they call it LP) and dozens more such gasses. The MQ series is really cool: https://robocraze.com/blogs/post/mq-series-gas-sensor

Note: The web links are not things I put up, and I do not make money off them. I only found them through web searches while knowing what subject matter I wanted to find.
Kinetic energy is relative too. Two cars moving at 100MPH in the same direction (relative to the reference frame) have no kinetic energy relative to each other.

You're right that if you match your reference frame to one car, that car becomes "stationary" until the collision, but after the collision it is moving relative to the reference frame. But that's the key--it now has kinetic energy relative to the reference frame, but not to the other car. As far as the pair of cars is concerned, all of the kinetic energy between them has been expended, because they are now moving together.

Of course this is assuming a scenario where the cars crumple into a single mass, i.e. they don't "bounce". I think part of the confusion in these comments stems from the problem being poorly defined. Some people are considering crumple zones, others are considering whether a brick wall is movable and still others replace it with another car for simplicity.

I do think the driver's ed manual is correct in some Spherical Cow sense, but I don't think its authors ever intended for the problem to stand up to Hacker News scrutiny. It's quite funny to me how innocuous things like this can generate these "unladen swallow"-type discussions on here, even though I'm participating.

The irony is that he is correct about the physics.

Some people in this thread think that you can take two cars and double the kinetic energy acting on both of them. If this were true, you could create infinite energy by repeatedly colliding cars.

Perhaps it isn't surprising that people who think this is true also disagree with his economics.
> No physician (nor individual) should ever be making a diagnosis or treatment decision based on a single line of evidence.

Talking in absolutes like this doesn't help the rest of your point. There are plenty of situations where a single result is sufficient to trigger a whirlwind of treatment decisions.

> More importantly, such results can help offer hard evidence to pressure one's physician to investigate a particular complaint, which can be difficult to convey or to convince the physician it's real. Physicians are often dismissive of things that they do not understand, or of certain classes of patients

If you've ever been sitting on the other side of a consult you would recognize that this statement isn't all that accurate of a characterization. As much as people like to believe they are outsmarting navel-gazing doctors, the reality is that with sufficient time and adequate resources most of these "complex issues" can be diagnosed and treated. The problem lies in that most providers have a 15 minute window to determine if the patient is part of the boring 80%, or if the patient's problem will require time you don't have. Until provider shortages are solved, that will be how it works in order to do the most good on the whole. Berating and pressuring them will just contribute to the burnout that in turn contributes to shortages. The source of the problem is above them.
LD_LIBRARY_PATH is not the only way libraries are found. The loader considers several other sources to find libraries. Assuming a sane setup, this will be a combination of ordinary ELF fields in each binary that gets loaded and other paths known to the loader. Relying on LD_LIBRARY_PATH can be very short-sighted on systems with many versions of the same library or multiple libraries with the same name. The loader must search the paths in LD_LIBRARY_PATH for each binary in order, and it will pick the first library that matches (unless you have other higher-priority paths set by other means). That may not be the one you really want. This can lead to unexpected errors at runtime. The better way is to set RPATH for the affected binaries to the location that has the libraries that it requires.

It is possible to end up loading multiple versions of the same library as well, if your environment and RPATH settings are not consistent. This tool will help you figure out if you have problems and why.
It's not clear to me what you're attempting to convey.

Those in applied math are pretty clear about what can and can't be modelled.

The majority of people I've met understand that almost nothing is stationary, the planet moves about the sun which moves about a galactic core which in turn moves through the universe all the while as molecules vibrate within various forms of matter.

None of which negates the AGW position.

I'd argue that a law based on culture or current knowledge is a bad law precisely because both knowledge and culture are always evolving. Laws that don't come with an expiration date should be timeless, at which point they couldn't be based on today's culture or knowledge.
I wanted to build a product a few years ago that would hang on the back of an aquarium like a hang-on-back filter, but instead of being a filter it would test dozens of parameters and send the results to a phone app.

You could fill up an aquarium, wait a week, then ask your phone what fish would like it. It might tell you to dechlorinate it and start it cycling before asking again.

It might know what fish you later put in it, and suggest things that would make the water better suited to those fish. If you need to raise the PH for African Cichlids, it might suggest crushed coral and show a paid advertisement for just such a product.

Surely the best place in terms of hospitality is Earth. But Mars, with all its problems, is likely still second. Likely.

We can deal with all martian problems.

1. Perchlorates in the soil? You can deal with them, say, chemically if you need some patch on Mars which is more Earth-like. After al you don't need to have the whole Mars immediately fertile.

2. Low pressure? Yes, but it's still better than vacuum, so spacesuits could be simpler, and also the cold atmosphere won't freeze you as much.

3. Far from Earth so Sun is too dim for solar batteries? Then take more of those batteries, they are becoming good, cheap and even light.

4. Far away from Earth? Yes, true - but we can survive for the year to get from here to there, and we routinely had ISS missions for half a year, comparing to ~9 months flight with today's technologies from Earth to Mars.

5. Low gravity on Mars and weightlessness in flight? Some are optimistic about artificial gravity during flights or even on the surface, and if we don't yet consider permanent settlements, it's imaginable to live a couple of years in that artificial gravity, and come back in a relatively good shape.

0. Radiation? How about better shielding for spacecrafts for the flights - both using e.g. water onboard and plasma clouds around, so different kinds of radiation would be at least reduced. Just like with artificial gravity, there are much more questions than answers in these areas, but at least we have physically plausible ideas. On the surface we can use underground houses - even with centrifuges.

In 2024 it is irresponsible to start that company off using gooby.

There’s plenty of mainstream programming languages that get the job done just fine without the hiring problems.

I’m 100% certain you don’t “need” gooby.

Hiring for gooby doesn’t scale, so unless your company’s goal is to stay small, don’t use gooby. And “the CTO likes it” isn’t good enough reason.

The original gooby loving CTO always leaves to spread more gooby to other companies and the owners of the company are left with a long term problem.

Just use the garden variety languages that there is a large talent pool for.

Do your gooby at home on your personal projects.

> decoupling via an explicit API makes change easier. Spreading state across your system via events (specifically synchronizing data across systems via events relating to how that data changes) creates coupling.

An explicit API comes at a cost; the way I'd put it is that the inherently lower coupling of events (because e.g. you can publish the same events in multiple formats, whereas a request-response API generally needs to have a single response format) means that you have more slack to defer that cost for longer (i.e. it takes you longer to reach the point where the overall system coupling is too bad and you need to introduce those API layers).

I'm not sure I follow what you're saying about sharing events relating to how data changes. IMO if you need a shared view of "the current version of the data", the right solution is to publish that as events too.

> E.g. Kafka uses gRPCs from the client and waits for a response in order to inject something into a queue. The communication between Kafka nodes is based on messages. The basic building block of any distributed computer system is a packet (request) being sent from one machine to another, and a response being sent back (e.g. TCP control messages).

I don't know the details of kafka's low-level protocols, but it's certainly possible to build these systems based on one-way messaging all the way down; gRPC has one-way messages, plenty of protocols are built on one-way UDP rather than TCP...

> e.g. an HTTP GET request from a browser, in the absence of a network connection, is just lost, it's not persisted to be played later, and so there is no way to build a lagging queue with HTTP GET requests that are yet to be processed.

Right, because HTTP is a request-response protocol. Whereas Kafka does buffer messages and send them later if you lose your network connection for a short time (of course there is a point at which it will give up and call your error handler).

I don't think the fact that HTTP works that way means it's desirable to just abandon those requests - e.g. in fact these days if you navigate to a page with Chrome when you have no network connection it will make the request when you're back online and send you a notification that it's loaded the page that it couldn't load earlier.

Your highlighted link is the wrong model to use here. The part you highlighted in your link is about elastic collisions in one dimension. Even with "spherical cow" physics, collisions like this are nearly always modeled as perfectly inelastic collisions. You don't model the cars bouncing off each other going back with the same speed that they were originally going - you model then as crashing into each other and stopping, with all of that kinetic energy converted to heat, a perfectly inelastic collision.

As per your "stationary" objections, the issue is that this is modeled as a very sturdy wall anchored to the Earth. Yes, the Earth will "recoil" some, but for all intents and purposes it can be modelled as completely stationary because its mass is so much greater than the car.
> autotune is almost always present in recent pop vocals

Autotune is often present in almost any decently-high budget studio recording of loads of different genres. Its just not obvious.

Autotune doesn't need to sound like Cher in Believe or T-Pain in any song he sings or Kesha. They're just cranking some of the settings to make those super obvious artifacts. When a sound engineer uses autotune (or the many other similar effects) you wouldn't even notice its there.

Speaking as someone who moonlights doing live music production, autotune is used loads of places.

When Cher's Believe came out, autotune had been a thing for several years. Its just that most people thought people didn't like speed == 0 until Cher made it a thing.
