> This assumes that all pesticides have the same effects at the same dosages in humans

Nah, my assumption was that the level of harm scales with the power of the pesticide in humans just as it does in, well, pests. (It's not true, but it's an interesting model to study.)

If we assume that relationship, it should imply that, if your vegetables were never washed once from the farm to your mouth, you'd be getting equivalent levels of harm from more- and less-powerful pesticides, since the amount of them sprayed on the vegetable would be in inverse proportion to their toxicity.

However, once you introduce washing, the amount of the pesticide you remove isn't constant, nor linear.

In fact, some pesticides are non-"organic" precisely because they have chemicals in them that make them more easily washed off!

So the better-engineered (less "natural") pesticides are both originally present in smaller quantities, and reduced in quantity more by washing. You might end up eating none of a synthetic pesticide, whereas an "organic" one might be all over your food even after washing. "None" is very different from even a little.

(Further, there are synthetic pesticides that are entirely safe for humans—or are even considered food by humans—but which are considered non-"organic" because we can only create them via de novo synthesis rather than in a bioreactor. Consider some artificial sugar that the human liver can process but insects cannot metabolize. If we sprayed it on plants, it'd be a "synthetic pesticide." If "synthetic pesticide" looks like that, and "organic pesticide" looks like, say, nicotine, which would you prefer to miss some residue of?)
You're generally right but DVDs (and books and CDs) can go media mail and that's very cheap. Like $3 for 3 pounds.

I was selling off some old PC Magazines and Bytes from when I was a teenager and was surprised that magazines aren't supposed to be shipped via media mail since they've got advertisements in them.
Maybe a different approach would be to have an automated robotic drilling "rig" on the ocean floor, which a ship could restock and maybe also power via a tether. As a bonus the under-sea rig could also have a data+power telemetry cable run to the shore and operations might continue even without a ship present.
Hey, this seems like a pretty useful website, one quick comment is that it does not seem to be easily usable by colorblind people. Almost 10% of males are red-green colorblind, so while normal people can quickly scan through the lists using color, colorblind people have to manually read each 'Ends in ...' or 'Ended ...'.

Not a huge issue in this case since generally you would lookup your product on the left side of the table and then look at a single cell on the right side, but it can't hurt to switch to an alternative color scheme - blue + olivegreen is one that I've seen pretty often.

How many times have you missed so far in this thread that there has been a git mirror of OpenBSD's source code for the last three years?

You lose the internal concurrency within the request (hoping this formatting goes through):

W---
C-H / X \
/ |/ \ \
R-I--I--I---I--I-I-I-I-H
\/\ / \ /|\ / /
A B U \ Y /
Z-----
R = request
I = internal processing
C = cache server
H = HTML output
X = early exit
A = Advertising server
B = Session cookie server
U = User record
W,X,Y,Z = application backends

Compare vs sequential processing:

R-C-I--A-H?-I-B--I-U---I--W-----I-X-I-Y--I--Z--------I-H

Note the user-perceived latency. For realistic sites, you may be looking at 400ms in parallel vs 5s or worse in series, which is a big difference in how long your users wait and how likely they are to bounce.

This also has knock-on effects in RAM usage. Say that your webserver is running at 100% CPU utilization. If a request takes 10x as long, it will have 10x requests in flight at any given time. They won't be consuming CPU, but they will be consuming RAM, as the server needs to keep all the context around that it'll need later. RAM can often be the bottleneck for many servers.

> Now maybe you are implying one rewrite the application so that R-I-A-I-B-I-C-I-H's steps don't have to be done in the order shown. But that's NOT what async/await does (at least not how it's typically presented/promoted).

It is if you're doing it right. That's what Promise.all()/race() does in ES6, or asyncio.gather()/wait() in Python3, or Future::join in Rust. If you're not doing this you're basically gaining nothing from async/await.

Ask HN: Are tech bootcamps the only way to get people out of poverty?
Trying to decide on the best way to teach people "how to fish".

There are a significant number of for-profit and non-profit companies, including some YC companies, that just give people "fish".

Don't get me wrong, this is great: some of those things are entire houses for people that don't have anywhere to live. However, this is not scalable to the millions of people living in poverty. In Mexico, for example, only 27 out of every 100 poor people will leave poverty behind.

I know coding/design/tech bootcamps have helped people break out of poverty, but are they the only option?

From a minute of googling, there’s roughly 5k satellites in orbit right now. Most of those are in a slightly higher orbit than Starlink’s (LEO) so they’re incrementally farther away, but would be in a better position to catch sunlight in the night sky.

And yet I, probably like everyone else who isn’t an astronomy enthusiast, haven’t ever looked at a light in the sky and known it was a satellite. They’re subtle, not dominating the night sky by any means, at least insofar as an untrained modern human can tell. Starlink would up the number of satellites by ~2x, perhaps, but would that be enough to change the basic equation?

the SR-71 , at that point in failure, would still have the opportunity to 'hit the brakes' like you would in your car.

Both vehicles can still veer wildly out of control even under deceleration, sometimes being exaggerated by the event -- so the plane manual recommends ejection rather than other remediating maneuvers because it's understood that further maneuvers may put the plane into such an attitude that ejection is impossible or futile.

So, that said, the SR-71 can still hit the brakes at the point by which their primary control surfaces fail; it's probably just a mighty bad idea to try to do so. There's a few instances in a car that might be a bad idea, too.

Imagine the steering wheel falls off in heavy moderate speed traffic -- in many cases it'd be safer to let the car drift across the road crowning and slow itself on roadside barriers than it would be to slam the brakes and take the full force of the traffic behind you colliding with your vehicle.

Screw it. Where's my automotive ejection seat?

Marketers have always been clear that their task is to manufacture desire. Beyond the basics of food, sex, basic security, etc, wants are cultural constructions. Of course you want what you want. You did not make yourself. Your culture has that job.

If we had had a century of relentless propaganda installing onto young brains stereotypes of the glories of a clear night sky, or clean healthy rivers (instead of trivial comforts & consumer gewgaws), do you think people would still 'want' the things that destroy our natural rights to experience those things quite as much as they do?

>As an example, go to google.com on Internet Explorer 6. No, I’m serious. You will find that it loads just fine and even functions, over plain HTTP. It’s only a small subset of functionality, but it does actually work.

Why should this be surprising?

What at all about google.com requires all the modern fancy javascript? Theres the search bar, which only need be a basic html text input box, and thats 98% of the reason I'll ever be at google.com.

I can guess that there are all sorts of little features crammed in that I don't know or care about, and that without the most up to date everything, some of those features may not be possible or may not be as efficient or whatever. Except there's a key phrase as part of that "I don't know or care about" which means its not why I'm at google.com whatsoever.

There's an attitude that seems to be common in SV, especially Google, that seems to put way way too much focus on using the latest things and having everything be automated and as low latency as possible....for what? Why? Its cool you can cut so many ms off some request that it pushes the physical limits of the metal, but I don't really care at all, in fact I'll be prompted to get angry, if that request is part of some feature I'm not interested in, and the one I am, is clearly neglected.

I know everyone isn't me, but I find often that my peers have similar feelings. Just look at Android Auto for a myriad of examples of significant buggy behavior that Google certainly has the manpower to fix, but chooses not to.

this talking point just doesn't die, and that's not how economics or profit maximising agencies work. It also fails to explain why, over time, advertising encroached on almost all platforms unless actively resisted and why it's so difficult to find a genuinely ad free service.

in short, these platforms work to maximise profit. ads serve to form another income stream, and as long as they don't push sufficient numbers of customers away, it's always in the short term interest of the provider to expand advertising income until the marginal gain equals the marginal loss in marginal revenue from the consumer base.

In most mediums and content/ subject matters, this is at a non-zero level of advertising, especially if everyone else is already advertising.

while advertising does really result in free services (if you do not account for negatives of advertising or assume all increases in consumption generate positive utility), it is not generally the case for most consumers that advertising results in cheaper products, or that you could pay 5% more and be rid of ads.

Thanks, I haven't seen that RFC before, but reading it now it seems it would be insufficient to support this use case without also supporting `let x: impl Future`, since the RFC deliberately chooses to expand to a temporary binding for `self`.

It would also appear to be deficient for the same parsing reason I mentioned, i.e. that you need some way to tell whether `2 + 2.bar!()` should expand to `2 + bar!(2)` or `bar!(2 + 2)`; the RFC appears to choose the latter, whereas a hypothetical `await!()` would want the former. This problem is called out in the RFC:

"Rather than this minimal approach, we could define a full postfix macro system that allows processing the preceding expression without evaluation. This would require specifying how much of the preceding expression to process unevaluated, including chains of such macros. Furthermore, unlike existing macros, which wrap around the expression whose evaluation they modify, if a postfix macro could arbitrarily control the evaluation of the method chain it postfixed, such a macro could change the interpretation of an arbitrarily long expression that it appears at the end of, which has the potential to create significantly more confusion when reading the code."
OK, OK, I was using laymans' terms. If you want to get picky about can't-prove-a-negatives then read it as "this research doesn't seem to provide much evidence that they're NOT."

From the article:

Federal government weather forecasters logged preliminary reports of more than 500 tornadoes in a 30-day period — a rare figure, if the reports are ultimately verified — after the start of the year proved mercifully quiet.

Monday, Dr. Marsh said, was the 11th consecutive day with at least eight tornado reports, tying the record.

That reads to me more like the exception than the norm.

I had several doctors from One Medical and they were not the best. However, there were a number of things that made up for it. Setting up appointments was easy, the locations were convenient, and you could even talk to the doctors via messaging on the website. Viewing and downloading test results could be done via their website also, and I've had to jump through hoops to get test results elsewhere.

However, to call it a true concierge practice would be a joke, in my opinion. I've never had the money for one (10k+ per year fee), but a friend of mine did have one of these, and at least in his case they were able to cure a serious back problem of his through cutting edge and non-invasive therapies. I wouldn't expect to find anything close to that at One Medical.

Still would say the One Medical membership fee ($200) is worth it if you can find a decent doctor there and if you're not happy with what you currently have.
We (Brilliant) do have an introductory course on quantum mechanics as well. It goes into more of the phenomena (like spin, photons, etc.) than this computing course that mostly focuses on information. Let us know what you think: https://brilliant.org/courses/quantum-objects/

If Brilliant isn't your cup of tea – check out mcintyre's spin-first treatment. Generally speaking avoid any textbooks with cats on the cover (ie. Griffith's is popular but only so-so IMO). That being said, we went with a cat on our course ¯\_(ツ)_/¯.

I wasn't trying to show that there are specifically natural factors as yet undescribed, just that there was a significant factor that we didn't know about until recently. This indicates that we could easily have missed others (natural or otherwise), and so any argument which assumes that our climate models are complete is flawed from the start.

> what we're really worried about is long-term warming, and this paper is not about that

Well, it sort of is, because it's saying that the argument against long term warming is that our short term observations are being caused by some cyclic behaviour rather than human CO2 emissions. We can't just carve off "long term warming" as a separate already-agreed thing (at least, not using the results in this paper).

Not really; there’s always constant low level radiation exposure in our day to day from background radiation. It goes up tremendously when you eat a banana a day. It goes up another few orders of magnitude when you get on a plane. We’ve got a huge corpus of constantly irradiated people (flight attendants and pilots). We’ve got a pretty good idea of how this works.

The after-party balloon effect
In recall a time probably 30 years ago or so. A large low pressure system settled in the Pacific northwest at the same time a high settled somewhere in the southeast. The counter rotation pumped moist air in across southern CA or Mexico and up to the northeast. We had rain every day (but not continuously) in Michigan for 29 straight days. It only stopped when a typhoon got sucked in to the apparently stable system. Point being that one unusual series of events doesn't mean anything. Neither did that record hurricane season in 200x that people claimed would be the new normal.
