You're missing the cultural insight needed to understand caste. For example, two people from New Jersey may tolerate each other even if one of their ancestors are from other places. Castes on the other hand, carries on from generation to generation. It's extremely hard to get rid of the caste label you're born with. Another factor is the level of discrimination involved. Caste is widely used to judge academic and professional proficiencies. It's extremely hard for lower caste people to rise up even if they work hard. They get denied and often demotivated in public. It gets much worse within India. Lower caste people are kept away from good residential areas, many commercial establishments and even village wells.
> Why does it benefit large numbers of others to have denser housing right here where my house is though?

It benefits large numbers of others to have denser housing in any highly populated area, particularly those that are desirable. If your house is in an area that can be described that way, then that's the reason it benefits large numbers of others to build denser housing right where your house is.

The problem is, obviously, when everyone adopts the same attitude you have. Then there's no "somewhere else" to build.

And hey, just like you're absolutely allowed to try to get the government to keep your area zoned as it is, others can try to get the government to loosen zoning. You don't have to like it, but they're doing the exact same thing you are - using the same processes to achieve something that's favorable to them.
Turbochargers do exactly that. They take waste gas/heat to turn a pump and provide more oxygen for combustion. Also look into the F1 ERS systems that recover waste energy.

Lessons from my first 18-months of Angel Investing
Everyone has the opportunity to learn about the dynamics of race within our world. In the corporate world, continual education and awareness of cultures and bias should be an expectation of every employee.

So many people study history and economics, but only the parts that are relevant to them... Learning outside of our own experiences actually helps greatly to increase chances of success in life by connecting with others outside of our normal culture and experiences...

It's a challenge that can be very rewarding if it is ritually practiced by all individuals not just in companies, but in life... Different cuisines alone that I've been exposed to (by new friends outside of my home culture) have been life altering in a great way. I understand context of current events and even TV shows and movies far better than I used to because of my exposure to cultures and languages beyond my own.

It's unfathomable to me how anyone could be resistant towards cultural learning, empathy, understanding, and growth outside of their own. It's a big reason why bias keeps resurging, because of that ingrained resistance (in this world) towards understanding and learning about each other.
I really enjoyed reading about Eddy's thoughts on angel investing. This is one of the few cases where an angel investor actually thinks deeply (and correctly I think) about the value they are bringing to a company they invest in.
I assume the issue here is not getting the Rust toolchain on a developer system, but Rust packages in APT.
> Instead of using air gaps, Sansone thought he could incorporate another magnetic field into a motor. This would increase this saliency ratio and, in turn, produce more torque.

This appears to be the novel part. It's an SRM but it appears to replace, or augment, the airgaps using some additional technique to increase the saliency ratio.

The text sort of implies that it's using a rotor winding, but I'm not sure; that would arguably make it no longer an SRM. Maybe he's added conductors into the airgaps to exclude magnetic fields via eddy currents.

Or maybe something else!

Whatever it was, it's very impressive to be making and testing motor prototypes on one's own, at his age or any age. There's a ton of work that goes into every little detail, like coil winding, or bearing alignment. Definitely great work!
In automotive, development of control algorithms for the engine is entirely “visual”, through simulink/matlab. You design the model on simulink, then it generates the C code. I don’t have direct experience outside the automotive sector, but I believe that this approach is used in other sectors like aerospace. Maybe designing models is better than writing low level code for control algorithms?

> There wasn't a choice when I bought mine.

Ad-supported or not has always been a choice for as long as Amazon has offered ad-supported kindles. I remember making this choice about 10 years ago, and I made this choice about a month ago when I bought my most recent Kindle.

If you bought it used or from a reseller, I don't know what to tell you, but Amazon gave you a choice if you bought it from them.

As a source, here is an Engadget article from the time when this option was introduced: https://www.engadget.com/2011-04-11-amazon-releases-ad-suppo...

You can clearly see that Amazon offered the "with Special Offers" version alongside the versions without "Special Offers". The ad-supported version was discounted by $25 back then. Nowadays, it appears to be a $20 difference on the Paperwhite.

What his father is experiencing is luck mixed with good genetics. Plus, additional support of good diet and exercise. Yes, we all can control our diets and exercise. However, we cannot control the medication that we take, which carry side effects. We cannot control what is in our food, we cannot control the air we breath, we cannot control cancer and hundreds other diseases. There are so MANY other factors.

If his father grew up somewhere where lead is a problem, I have a feeling the outcome might have been different.

The whole article is useless. My grandfather was an awful person, smoked all his life, drank most of it, and ate whatever he could. Lived to 78 and was healthy, at that point he committed suicide as he could not live without his wife, which passed away few months earlier. Ironically he was an awful husband.

This is all anecdotal and useless.
Because most of these stories are sensationalized omitting a lot of facts around who's that kid, who are his parents and how much help did the provide him. It's also often a PR stunt to promote an underlying company or organization. This kid didn't developed anything in his parent's garage, he had access to sophisticated industrial equipment and you bet someone helped.

Of course, there are outliers, but most often it's borderline fake news.
This is a known issue with ungrounded electronics in general.

Apple Macbooks are particularly bad because the enclosure is metal and the standard plug (the interchangeable part of the charging brick) that is sold in most parts of the world is not grounded.

In my country (in Europe) a Macbook charger is sold with a 'type C', (AKA EuroPlug) which is not grounded. The extended cord that comes with the charger is a 'type F' plug, which is grounded. [0]

For me, this results in always having to lug around the extended cord with the charger, as the non-grounded variant makes my Macbook unpleasant to use.

Reading about food waste has always bothered me. Growing up in a Jewish orthodox household wasting food was verboten. There is even a mitzvah (commandment) regarding wasting food and or resources[1].

I think that mindset drove me to be named the "leftovers king" by my extended family, as I repurpose leftovers into delicious meals.

There are a couple techniques that can help turn fridge leftovers into really good meals besides for soup. You can make an amazing Frittata using whatever leftover veg and protein you have.

If you give away pizza for free for 3 months, and then stop, even if you announced ahead of time that you'd do that, people will still be upset when they show up for their free pizza after that 3 months.

If you give away free pizza for a week, it won't be a big deal. After a certain amount of time, people expect it and will be quite upset when it ends, no matter how you try to prepare them.

Of course, others are more reasonable. But there are far too many who will simply expect it forever.

The trouble with 64-bit DMA in Linux
I think what I'm getting at is this: it's wrong to think that there exists any such thing as "the organization". Like "the government" or "the people", it's a useful shorthand but it doesn't really point to anything specific.

The "trick" (not really a trick, just basic politics as correctly pointed out by other commenters) of cultivating one-to-one relationships stems exactly from that realization. There are all sorts of reasons why people oppose technical solutions, most of which have absolutely nothing to do with technical merit or the collective well-being of the set of people defined by "the organization".

My ideal of how the world ought to work is a perfect, strict meritocracy. But people play games on me, hence I have to play games on them in self-defense. It's like an iterated prisoner's dilemma, defecting is at its most powerful when the expectation is that you will cooperate.

> His resting heart rate is just below 60 beats per minute. The steps pushed it up to 155 beats per minute. (His maximum heart rate should be 220 minus his age, 80. That’s only 140 beats per minute — far below what he is capable of!)

Sorry, that's not how this works.
220 - age is a very crude and not very good guess at the heart rate for a population. It is not YOUR max heart rate, and your max heart rate being higher or lower than that is not a sign of health. It is likely just a sign of your particular heart. It's worth checking in on it every few years and knowing yours.

On the other hand, resting heart rate of under 60 is good. Under 50 is likely better.

> My overall point ... is that we're much better off focusing on concrete ecological issues that can be solved today (not draining aquifers, better agriculture practices, elimination of weird farm bill subsidies to harmful crops, etc...).

Thank you for giving some concrete examples of what you mean.

However, I'm still not convinced by the "that can be solved today" criteria. One key problem with such criteria is that someone can say "that can't be solved today" in order to avoid taking action. What is your response?

In my other comment, I offered a very high level summary of how science, technology, governance, economics, and finance relate w.r.t. climate change. I was hoping to see your response. Your response these very much connects to the "that can be solved today" criteria.

Sustained investment in research and development is important because science and technology can expand the solution space. In parallel, more public awareness can increase the political will for increasing the budget for action. (Of course, there are many other components necessary for humanity to address the situation.)
My experience teaching high school kids was just the opposite. Quite a few will stay with a problem long after most so-called "prudent" adults have moved on.

As adults, we forget that 17 year olds are still living their lives in a world of what they don't know, not in what they know. And once they do know they can be very insistent about being right. Because, it's all they know.

It's also how a team of 16-17 yr olds can somehow manage to win when the odds are completely against them. All they know is what they want to see happen. And they will keep trying until they succeed, the clock runs out, or the other team makes it painfully obvious by completely routing them.
Not too hard to look them up. It used to be so, before stability control systems. Not anymore.
Why are you here flaming the Rust devs for having the audacity to dare release a new version of their software, instead of talking to the packagers that distribute years-old versions?

Having the new borrow checker finally on in all cases is nifty. For valid programs the behavior is the same as the previous version, but in the event of a compiler error, previous versions would still show you the output of the old borrow checker. I've already had one case where someone came asking about a confusing borrow checker error message and I just had to suggest that they try compiling with 1.63 and the new error message was clear enough that it answered their question immediately.

Now we just need to do it all over again once Polonius finally arrives. :P
> Send 1KB over a 1GBps network

This is said to have a 10μs latency in the chart. But I'm fairly sure that is a calculation of bandwidth based on 1KB / 1GBps

10μs is about 3Km, so at most a 1.5Km round-trip.

For a chart labelled latency, I'm surprised to see bandwidth calculations included. Any network hop would actually have far greater latency, if nothing else because communication typically involves more than a single round-trip for acknowledgement, etc.

It might be worth making it clear some of the numbers are about bandwidth not latency.

Ok, here's some rope <https://telescoper.wordpress.com/2022/08/10/recalibration-of...>

Telescoper is an anagram of Peter Coles. It's his blog. He's a well known physical cosmologist <https://en.wikipedia.org/wiki/Peter_Coles>.

Adams et al., authors of the preprint linked in that blog entry, are all well-known astronomers. Adams is a research associate and Observational Astronomer at <https://en.wikipedia.org/wiki/Jodrell_Bank_Observatory> specializing in high-redshift galaxies, and is in several large-telescope international collaborations (ESO, SKA, MIGHTEE, LADUMA).

The punchline: those seemingly super-far-away galaxies are getting much much closer as JWST's calibrations proceed according to plan.

Probably. Given some years back the US moved to a first-to-file system, getting an initial patent application filed to establish that date is probably not a bad idea and isn't too terribly expensive.
I do not see why exclusive distribution is always a bad thing, unless one is also claiming that a manufacturer has no right to sell directly to end users, such as Tesla.

Would a carpenter be able to only distribute their furniture directly to their customer? A hotel be not be able to exclusively take reservations from their hotel guests? An independent videographer not be able to sell their own videos however they want?

I think the solution here is to reduce copyright to 10 years. Or maybe 15. Then there is no more “exclusive” distribution.
> there is a certain kind of lock-in.

But vendor lock-in is one of the perfect factors to considerate when monetizing these services, as are short notice periods, amount of work required for migration, and time pressure. I can imagine they have more impact on final price than things like value of service, SLAs and warranties. After analysis, Gitlab found that the current prices are the best balance between getting revenue and users migrating away.

I compare this with Photobucket: it was a free image hosting site that allowed hotlinking and ended up used everywhere. One of the largest group of users was the small scale online merchants, they hosted lots (lots!) of product photos there and hotlinked them to Amazon, eBay, etc. Then overnight they changed the free users features, disabled hotlinking and replaced the images with a placeholder, unless users paid for a subscription costing USD 400,00. The hosting and bandwidth cost were not the important factors: there was a very long tail and most images were loaded just once in forever. There was a lot of less expensive sites doing the same, but the incentive for paying was the amount of hotlinked images that needed to be changed manually in a very short notice -- and the small merchants had no time nor resources to do this quickly enough, before the lost sales pile up or their ads get reported for not featuring the images. So I can suppose a lot of them just paid up. This strategy would not have worked if accounts were grandfathered.

That's the reasoning for Gitlab (and Github, it's just a matter of time): how much effort would cost to migrate away and how the projects would be disrupted until it is finished? As git is distributed and users are technically versed and can automate migration of the centralized features, it's no wonder that it cost less the Photobucked. However, there must be factors pushing the price up: one that I can easily imagine is amount of Go projects that download dependencies from repos with URLs hardcoded in source. And all their cloned copies, packaged tarballs, etc.
That makes it sound like this could be used to improve Tesla's motors.

That's not true. Nuclear waste is so minimal in volume nuclear power plants can just sweep it under the carpet. Or more specifically, just store it on-site. Modern nuclear reactors can even use the waste of old reactors as fuel and reduce it by another 80% or so. Dealing with nuclear waste is really no big deal. At least for medium term storage.

Storing waste so you don't have to look after it for thousands of years is admittedly more difficult. Then again, future generations are always impacted by the choices we make today and I'm pretty sure the kids 300 years from now would rather deal with the cleanup of our nuclear waste than with the consequence of global warming.
This is a flawed analysis.

1. Permian basin itself will provide fuel for at least 300 years and right now if you have skills, you can get well paid job in Texas.

2. Texas has so much Wind and Solar footprint already it will make most European countries headspin, and we are not even adding Iowa! So, US has massive set up already and the best part is, unlike Germany, US has windmills where Wind is.

I recently did the Foobar with Google challenge and yeah, I feel this.

Question 4b was a Max Flow problem. And question 5 was Polya's enumeration theorem.

With both of those, I was not aware of the algorithms beforehand. I understood what 4b was asking, "Ok, I need to find out the bottlenecks and figure out how many bunnies I can feed through the maze at once." And 5 was more incremental. "This is a matrix.", "Ok, I know if I know the number of distinct row mixes and column mixes, I could also maybe figure out how many distinct matrix configurations I could make", etc, which led me to Burnside's lemma, which led me to Polya's enumeration theorem.

It took me a long while to make all those increments however. Given 30 - 50 minutes, I doubt I'd be able to even implement Polya in the blind.
I'll just casually mention here that in the last week or so someone on hn claimed very insistenly to me that they, as an asian man, were the primary "victim" of modern dei policies and that white people weren't harmed by them.

You cannot both be correct in the reasons you dislike dei. They're contradictory. (You could both be wrong, but you can't both be right).
