> 75% of all electricity consumption is too low to be a "valid option" for decarbonizing electricity? We have different ideas of what's valid.

The US already generates ~40% of its electricity from carbon free sources. An increase to 75% represents only about a 60% reduction in fossil fuels from the current status quo. This is absolutely not a solution. We're still advancing climate change. Halving the time it takes to reach a disaster is not even remotely close to the same thing as averting a disaster.

> 37 of them started construction in the 1970s. That's a high project failure rate compared to any other generation source

Yes, because of Three Mile Island. Most of the cancellations were for reactors that started in the 1970s, because the US mostly stopped constructing reactors in the 1970s. You don't have cancellations for projects that began in the 1960s because those projects finished before Three Mile Island. You don't have project cancellations in the 1980s and 1990s because the US largely stopped starting new nuclear projects.

This pattern of cancellations demonstrates the fact that the high failure rate is due to political pressure, not economic unsuitability of nuclear reactors. Serialized production yields costs per kilowatt hour well below your estimates for renewables even without the cost of storage.

And no, if we look at reactors that are no longer in operation we don't see a much higher cost [1] [2] [3] [4] [5].

Serialized nuclear construction is by far the cheapest and most effective way to eliminate carbon emissions from electricity generation. Intermittent sources are cheap until they reach saturation during their time of production. Then costs skyrocket when storage becomes necessary. And even more importantly, nuclear is the only proven way of accomplishing this.

why should someone go into your store when they can get the same products online

Easy answer: because they'll walk out with the book they were going to buy and the book next to it. We used to have second-hand bookstores that would send you catalogs that you would peruse (by subscription, you'd actually pay for the catalog), and you could order from that. It was worth the money, no recommendation engine comes close to browsing a well-curated store.
Algae in the ocean, mostly.

But also, any growing plants - you could compute for every kg of dry plant matter, how much oxygen is released, as the dry plant matter is almost entirely carbon produced from breaking up CO2.

So unless you're collecting tens or hundreds of kilograms of dead plants from your roof every year, it isn't producing much oxygen.

It might also be it takes years to learn the skills to build something yourself.
The Infinite Earring
Maybe someone can share/explain --

Purple Air sells you a sensor that you can install, and then takes the data, displays it on their website for lots of people to view, and then presumably makes money off the data you send them? Why should you have to pay for the sensor then?
If you like second-hand bookshops, visit Hay-on-Wye. I'd recommend crossing the Atlantic to see it even. It's in south Wales, and it's a whole village of second-hand bookshops. Many are huge, some are tiny and very specialist (horror, detective fiction, etc.) Every year I spend three or four days there browsing and reading, and doing some walking in the mountains as well.
Perhaps so the animations are outside of the drawing area?
> Why would I care about not seeing NSFW images?

The issue with NSFW images is not you seeing it on your own computer, it is other people seeing it on your computer (e.g. while walking by or for some other reason).
> I actually really appreciate second-hand books.

Do you think this is some kind of controversial or unusual opinion?

Almost everyone loves second-hand bookshops. They just don't buy many books in them. And when they do the profit for the shop is tiny. So it's hard for them to keep going.
Show HN: Strikr – Simple Remote Technical Interviews with Code Execution
Ask HN: How do you decide to be a very early employee at a startup?
Assume that:

- you someday want to start your own thing (bootstrapped or VC, no opinion) but you're in no rush, you think experience at a rocketship does bring some value

- you get 0.5-1.0% in options

- you believe it's a good startup with a cool idea, but can't predict how cool

- you could easily get a decent (not amazing, just decent) job paying much more at a BigCo and could bootstrap your own thing as a side hustle

I think I don't understand the early employee mindset (say <10 people, pre Series A) and would love insight from people who've been thru this. Thank you in advance!

It does. In the past, there were cards in the backs of books with date stamps.
Your explanation ignores the difficulty tall women face finding partners in wealthy countries and so addresses only part of the data. E.g.,

"In western postindustrial cultures, taller women tend to have less reproductive success (RS) defined as number of children surviving to reproductive age, than women 0.7–1.7 standard deviations below average height"

Yes, if you were to duplicate the code, you'd be doing the same thing as monomorphization. But it's possible that they wouldn't actually duplicate it, and do something else that would be smaller, like, casting to a void pointer or something.

The compiler can do some optimizations like this, yes, but there's a lot more work to do in this area.

As an example of something folks still do by hand sometimes, take the starts_with method on Path: https://doc.rust-lang.org/stable/std/path/struct.Path.html#m...

It looks like this:

pub fn starts_with<P: AsRef<Path>>(&self, base: P) -> bool {
self._starts_with(base.as_ref())
}

fn _starts_with(&self, base: &Path) -> bool {
iter_after(self.components(), base.components()).is_some()
}

Why split this into two functions? Well, you can get smaller code size this way, because you're sort of "hand-de-duplicating" the parts that aren't generic. Once we call .as_ref, everything else is actually identical, but the compiler isn't good enough at this yet to do this itself, so we do it by hand.

I wouldn't say this technique is super super common or well-known, just for the standard library (because it's used everywhere) and for folks that are sensitive to code size, like embedded or wasm people.
>Spotify said: we did charge more, and then we decided to stop doing it.

Yes, because they couldn't charge more. People wouldn't accept it, so they blamed Spotify instead of Apple, because they weren't allowed to. Of course they can't do differential pricing if they aren't allowed to show that.

>Literally nothing to do with our discussion which is about your bogus assertion that apps are forbidden from differential pricing.

Well it is. In reverse of course, because Apple thought that they'd lose revenue.

>Classic example of cognitive dissonance: ignoring Phil Schiller, the guy who is literally in charge of the app store, telling you that you are wrong ;)

Also the guy who is responsible for that. Hey, Wordpress, Spotify, Netflix, Microft. They are all "wrong". He is the leader of the insane asylum.
Often it will be stored with plaintext metadata.
I’m referring to songs that the other apps also have. As an example, both Spotify and TIDAL have licenses for - and will happily play - the vast majority of the North American catalog. Spotify has more user-created public playlists, but not a ton more music.
fwiw, Abebooks has been a subsidiary of Amazon since 2008
You don't need to muck around with encryption headers for this. Just install gpg, generate a RSA-1024 key pair, and use the public key to encrypt a rickroll video or something.

Sadly this is one of the sanest answers. ./* or always using -- are coping mechanisms. We've internalized the UNIX warts so hard that we no longer perceive them.

I've moved to writing scripts in python instead. It's horribly verbose, but at least it's predictable and doesn't require the use of noisy disclaimers on every call to defend against rare cases.

There's definitely a need for a terser sane scripting language, but I haven't found one yet.
Both can be true. CBP frontline officer is not a highly sought after job and they have a lot of difficulty hiring people to go work in the desert.
Yeah, The Register can often be witty and irreverent, and I wouldn't complain about that, but that kind of wit only works if there's an actual point behind it. Jumping on the apparently popular bandwagon of squeezing out "drama" from the Linux kernel mailing list isn't adding anything of value.

It also seems a bit ignorant to call the submission "half-baked" just because it needed to be worked on and because someone pointed that out (also) in a slightly irreverent way.

All of those points you bring up about the feedback they got seem like just business as usual for a larger merge of code to a carefully developed FOSS project.
I really don’t like this pricing model, but maybe that’s just me.

If it works for you then great, and I can see your logic (you are trying to price discriminate), but it means I probably have to implement it before you tell me how much it costs (particularly as I’m assuming that higher revenue uplifts mean a lower % cut). Additionally this pricing model does make some assumptions on the margin of your customers.
I do it on Windows using the python executor py. So I'll run something like py -2 or py -3 or even py -3.8 to start the correct version of python when I'm not inside a venv.

Also the same goes for modules. Since I've installed youtube_dl in my global python 3 I'll always run it like py -3 -m youtube_dl and update it using py -3 -m pip install youtube-dl -U. Or to create a new python 2 venv (for whatever reason) py -2 -m virtualenv venv.
There’s actually a web app that does exactly what you are describing. It seamlessly converts playlists between apple music to spotify and vice versa. Check it out https://playlistor.io/ .
Here in Canada, depending on your ISP (Rogers, in this instance), the activation is instant. In fact, they only give you a two-hour window to get home and plug your modem in, otherwise you have to call and have them re-send the activation ping.
Yup. There are a lot of problems with Python, but you're not going to run into them for several years. If you're running into them right away then you're probably not a beginner.
I admit I can't see anything wrong here. What's the bug?
It's pretty widely accepted that exFAT should be avoided on Nintendo Switch because of data corruption issues. So I don't think it's just Apple.
I don't think there is anything to suggest he was gay.

It is not just that he had no way to approach women. He had no friends either, neither males nor females. He did not talked to anyone except parents and 1-2 friends his mom found him when he was preschooler. (Third refused to associate with him anymore.) And the two treated it as chore. He was profoundly alone, except like minded people on Internet where he had a lot of contact.

And it was like that for years, because he refused to go to school after one day and was learning from home - visiting once in a while for contact with teachers. He socialized on Internet and world of warcraft. Literally.

It is just that. His inability to have girlfriend was extension of him being profoundly alone and profoundly incapable of any relationship.

But, he was not gay. Homosexuals have nothing to do with any of this.
Welcome to Linux kernel development. By lkml history, this tone is very mild. There are many examples of far worse commentary and personal attacks on devs. I’m not justifying this by the way. Linus can be a very smart jerk, and as a leader (THE leader) he sets the tone for what’s acceptable in the community.

Earth has lost 28 trillion tonnes of ice in less than 30 years
Hey HN!

I wanted to share Strikr, a simple online tool for doing live technical interviews remotely. I actually built this tool earlier this year as part of a larger project, but due to COVID and other reasons, I never moved forward with it. I decided to strip everything down to just the interviewing platform and make it available at a super low price to make it accessible to anyone hiring right now.

The IDE is built with Monaco, which is the underlying editor powering VS Code which gives a great experience. The interviewer and candidate can see everything typed and executed in real time, and code execution is supported in 13 different languages. I'll also be adding video chat by integrating the WebRTC tech I built for another app, Water Cooler (https://watercooler.work), but that isn't quite ready for prime time.

I'm primarily just putting it out there to gauge if there's enough interest to keep moving forward with the project. Are there more fully featured options out there? Absolutely, but the hope is that with the low price point it'll be an attractive option for employers that don't need all of the extra bells and whistles of the more expensive and mature products.
It's uncertain whether Tesla has won. Less uncertain is that a lot of the existing manufacturers have already lost.

I've found that SO is great for questions that aren't too basic, but aren't too hard either. Overly basic questions get downvoted. Really hard questions don't get answered (not in the Spark niche at least). Questions that people with 2-4 years of experience ask seem to be the bread & butter of SO.
> The data Tesla collects from users, their environs, interests, tendencies, travel habits and the range of behaviors will arguably be more valuable than the engines and high-performance batteries powering them. This enables Tesla to hone the customer experience, while discerning where the market will veer next.

I for one, hope the companies focused on making great car hardware win this battle, not the companies that want to turn the car into a giant data harvesting platform.
Book publishers do the marketing all wrong. They publish the first in a series as a tease to buy the rest. They should start with the second book in the series, then people would be haplessly impelled to buy the first one!

Understanding of causality is very likely an emergent property. While extremely important, it's unlikely that we have some hard-coded low level architecture of causal inference in brains. It probably will just arise as a necessity of grounded understanding of the world.

Please post credible evidence that Joe Biden is a pedophile. As far as I know, the closest thing the Trump camp has are some videos or photos where he's said to "act creepy" around children, but that's just baseless stereotyping typical of the QAnon party.

Show me formal accusations, complaints, arrests or investigations that implicate Joe Biden in any sexual crimes against children.

Meanwhile, Donald Trump has partied with Jeffrey Epstein, is on tape bragging about how easily he can get away with sexual assault, and has an entire Wikipedia page[0] dedicated to the sexual assault charges against him.

Submitted a quick instruction on how to make an air purifier.

Link: https://news.ycombinator.com/item?id=24251509

Copy/pasta to help folks:

Note: this is not my idea, but I have used it for 2 Cal fire seasons successfully.

1) Acquire a box fan

2) Acquire a large "FPR 10" rated filter from home depot

3) Duct tape filter to the out flow side of the box fan. Make sure the arrows on the filter point in the correct airflow direction.

This works dramatically well for very little dollars and can help save your lungs if air purifiers are not available or expensive.
In the UK we commonly have 2 to 5 year fixed interest rates on a 25 year mortgage, with the remaining years at a variable base rate + X%.

I think this achieves a similar result, as anyone who leaves their mortgage unchanged beyond the fixed rate period almost always ends up on a punitive rate.
My issue with Emergency Use Authorization is by how many people use that to mean “FDA Approved”.

The public is not smart enough to tell the difference between something that passed 3 clinical trials and things that did not but are available for use.

The FDA brand is diluted now. I think this needs legislative intervention.

Another damaging thing is that this is used outside of the country, people who shouldnt care will look at the mere acknowledgement by the FDA as validation.

Its really shocking to me.

Hey! While we're mainly looking at the product metadata, our algorithm also learns user-specific patterns for each store. That makes the recommendations hard to copy - since two people could look at the same product but get different recommendations. Also, what to recommend to a particular product can depend on more factors than only person & product - seasonality & trends also influence (to varying degrees).
Wanting to start your own venture is a noble ambition -- I hope you do it! Working as an employee at either a startup or a big company will not prepare you in any way for being a founder. But if the work is fun and you think you will learn something useful, then by all means go for it.

Don't compromise on your salary, you should be paid the market rate. Oh, and the options are probably worthless.

Thank you! This is really close. It doesn't solve my personal need but it may work for others.

It only works with Apple Music, which isn't the app I use. Also, when I paste a public Spotify playlist URL (source), it asks for my Apple Music credentials instead of creating a public Apple Music playlist or if that's not possible, generating a page with play links.

Still, it's trying to solve the same problem and may work for others. I appreciate the link.
