Do you have any recommendations on how to learn more about this?

My brother has a steep hill on his property and Ive been wondering about the feasibility of PSH. How high the tank should be, the equipment, the power output.
Thousands? Quick googling suggests it's only dozens of dollars. Unless there's a better place to offload them than those top results.
Flywheel energy storage has been proposed many times, and built a few times. Flywheel-powered buses have been deployed. Not too successfully.

EMALS uses a big flywheel to power aircraft carrier catapults. The flywheel energy storage seems to cause most of the problems. The next generation of that system may use ultracapacitors.[1]

Apple Will Make You Buy a $20 Charging Brick to Charge $1k iPhone 12 Pro
Something Awful, a Cornerstone of Internet Culture, Is Under New Ownership
Company aside, in a weird coincidence I recently came across an interesting slide deck from a meetup (?) here:

https://speakerdeck.com/takutakahashi/ceph-on-zfs

I was impressed when I found this slide deck and it was in japanese, and from a thoroughly japanese company here. If you don't happen to know japanese, just go like... 3 slides in and you can see the creator is from GMO, also there are some images.

If you're not into infra you might as well stop reading here, but basically the idea is to get durable crash-resistant replicated storage on kubernetes by actually combining two CSI storage providers:

- Run ZFS as your on-disk file system (for absolute durability without bitrot and some of the other benefits) for each node

- Add the openebs/zfs-localpv[0] to dynamically provision zvols with say xfs or ext4 to make drives for ceph to consume

- Add Ceph via Rook[1] to get synchronous remote replication on every write (if you want it), and give ceph the drives you made (the zvol(s))

- Expose storage to your kubernetes cluster that is replicated (depending on how you set up ceph) and easy to back up and/or duplicate at the node level (w/ zfs send). You can back up at multiple levels, nodes themselves (with some replication lag since zfs doesn't so sync replication) and the workloads that run on them (which are sync replicated across the network).

There is some overlap in these tools -- ceph's relatively new bluestore engine does checksumming now and self-heals, so there's not so much reason to use ZFS at the lowest level at all, but ZFS does have some features that ceph doesn't, and is somewhat easier to manage with less moving parts in user space.

It's fine (and a good thing) for everyone to have a deep understanding about how the rules work and to have opinions about how the rules _should_ work. This is true whether you are talking about the current state of anti-trust laws and how they are interpreted by the courts, or the current state of patent laws and how they are interpreted by the PTO and the courts. It's complicated, though, and there are a lot of side effects when you make changes to what is in effect a very complex system. What might work well for one industry might not work well for other industries, and "I know justice and morality when I see it" works about as well as "I know obscenity when I see it".

The real problem though is that most people don't have this deep understanding, and what's worse, don't realize that they are really clueless. This is especially true with software engineers, who think they can understand everything. (About the only more arrogrant people are physicists at certain national labs who are sure they can design cluster file systems, since after all, it all resolves down to F=ma, and they know physics. :-)

The problem is that law and regulations make the x86 instruction architecture look regular, orthogonal, and logical. And having software engineers trying to draw legal conclusions --- applying the facts to the rules as they current stand --- is about as scary having lawyers designing a storage stack. (There are of course exceptions; I know of some lawyers who started out in computer science, and then went to law school, and there are also some computer programmers who have learned enough about law to understand how little they actually know, but at least know when to call in the specialists.)

But sure, we should know lots about public policy issues, and dive down deep enough so that each of us can understand the tradeoffs --- and in general, there are always tradeoffs to pretty much any public policy preference. Trying to make assertions without paying any attention to nuance will get you something like a certain US politician currently up for re-election. (And to be fair, the reason why the law has so many exceptions and irregularities is due to trying to work around the downsides of the obvious simple rules.)
It’s pretty stunning to me that this tool could have been made without its authors recognizing that it serves a very specific belief system. No mention of that fact anywhere.

A simple act of etiquette would be to recognize your own astounding biases and at least put up a little warning sign or something: “Made by and for American Progressivism Activists”.
Ask HN: Does Hacker News have an .onion link?
Since this is a tech savvy community that values privacy, are there any official or unofficial Hacker News .onion websites ?
Your original comparison was a newspaper to the constitution. The constitution has in fact changed very little. There have only been 17 changes(amendments) to it since 1791. 17 changes in 229 years is pretty static and add to that any change requires that 2/3s of the states to approve.

Also no New Yorker thinks the Post is a serious newspaper. Its most well known features are bad and tasteless puns cover headlines and a gossip page called "Page Six" which itself is not even on the 6th page of the paper.
"but is the FBI not supposed to investigate these things?"
They did. They concluded that the Steele dossier was probably not reliable. They investigated anyway because their agenda was to get Trump out and throw Flynn in jail.
That’s a good point - I went back and forth on what to base my sample slides off of. Ultimately, it was important to me to protect the privacy of the founders I work with, and was worried that any non-meta example I used would be taken to resemble any company I had worked with. I also didn’t want founders to copy the deck wholesale, but instead to adapt it to their specific situation, so I chose an example that doesn’t apply to any startup. Of course, the numbers used shouldn’t be taken too seriously anyway :)
As Apple makes their chips faster and more efficient and as phone batteries get bigger and bigger, app developers rise to meet the challenge by producing increasingly sloppy software that can afford to be incredibly wasteful because raw speed of the hardware is masking its cracks.

Try to run Instagram today on an iPhone 6, you won't be able to even scroll a feed of static images smoothly without hitching. Imagine what it is doing to the battery.

The movies have forgotten they are fantasy, and come to the conclusion they are Sci-Fi.

The worst moment, by far, was in the 2nd of the latest trilogy, when the chinese girl (Rose?) monologues about how the real evil in the world was greedy war profiteers and evil capitalists. ffs. This is a universe in which the more powerful faction outwardly identifies itself as the Dark Side, fueled by the power of Hatred, and known for destroying planets at a time.

(although the real worst part was, surprise, 100,000 star destroyers, all of which can destroy planets)
> Now mostly everything just works

'Mostly' is the key--and the problem.

I've been using Elementary OS as a daily driver for at least a year, maybe two (and before that I used Mint for several years). For the most part (there's that pesky word again!), it works quite well. And it really is beautiful--aesthetically, I quite like it.

But boy do I wish that bluetooth would work reliably. Since working at home full time, noise-cancelling headphones have gone from 'nice to have' to 'nearly essential'. It worked more or less fine for a while, then some update broke something and it stopped working. Now it's working again, kind of, but connecting a pair of headphones causes most of the entire UI to stop responding for a full minute or two. Sigh.

And maybe the next time I update it will be fine again. Who knows? And that's the problem: every update feels like Russian roulette. And this isn't even a laptop. I use this thing for work; I do not have time to dick around all today troubleshooting obscure bluetooth problems.

If I'm going to continue to use it, I guess what I need to do is stop updating (or only update specific apps, like firefox) once I happen upon a relatively 'stable' configuration. Security updates be damned.
I've seen postulated mechanisms by which increasing levels of self modeling get selected for, demystifying paradoxes has some examples.
SpaceX gets FCC approval to bid in $16B rural-broadband auction
"There is a risk of infection if the water is not sterile or the device is not cleaned after use. If the device is used improperly this can be harmful.[4] In fact, proper application suggests the use of boiled water or saline water. In 2018, a patient was reported to have contracted Balamuthia mandrillaris after one month of using tap water filtered through a Brita water purifier for nasal irrigation.[5]

Rare cases of fatal naegleriasis have occurred due to nasal insufflation of the amoeba Naegleria fowleri (the "brain-eating amoeba") from untreated tap water. In 2011, two people died from Naegleria fowleri infections tied to using Neti pots containing tap water.[6]"

The company is covering their own ass and part of that is telling their employees that it's important not to leak stuff.

You can redefine the discussion all you want, but my comment was related to how people have changed their views on speech in the age of social media and the internet (and especially since 2016). I don't really care to rabbit hole right now about TOS policies on these websites, but I do care about how we collectively think about principles like free speech and what constitutes a "threat" to democracy.

So, to directly respond to what you're bringing up, laissez faire moderation policies are not a threat to democracy.

My visa was rejected twice before I gave up. One of my friend was rejected 3 or 4 times before he was granted a visa, in a span of less than 1 year. I don’t think it’s out of the ordinary to see someone’s visa rejected 8 times before one was granted. The F1 student visa requirements are quite ambiguous and leave a lot of room for “interpretation”. Most are rejected because they cannot demonstrate “strong ties” to the home country to prove they will return after graduation. Now tell me how do a senior in college with no asset and no job prove they will return to the home country after 5 years of graduate school.

Protein folding is pretty nearly solved in the last few years, as demonstrated by AlphaFold.
What connects the story to Russian disinformation? It is a wild story but nothing indicates specifically that Russia is involved. Per the story this material has already been submitted as evidence to a Senate/FBI investigation quite some time ago so if it is completely made up the FBI and/or the government can say so. I don’t think it’s right to censor an article from a legitimate print publication with investigative reporting staff, even if they tilt towards sensationalism. This isn’t a fake news outlet with totally fabricated stories.
Weird that nobody has mentioned Benghazi yet.

Tibet, Uighur, Mongolia, India, Mekong...the CCP are making a lot of enemies needlessly. And their new friends are just that, new and unproven. The Dragon Dream can turn quickly into the Dragon Nightmare, even worse than what the CCP did to their own people, reportedly, during the Great Chinese Famine (10-50M dead) and the Cultural Revolution (3M dead is the last number I remember) within living memory.

Has China considered that the 6B+ rest of the world is “letting a hundred flowers blossom", watching and waiting while the CCP stumbles around so unwisely? The CCP has stewardship responsibilities over 1.3B human beings...overreaching has consequences, and the world may not step back next time if another 30M Chinese are in danger of starving to death.
The article is a nice piece of spin. It seems they started with a narrative and fit the facts to it.

I've taken the trainings referred to in the article and I never once thought they were designed to dissuade discussions about antitrust issues. A more banal interpretation is that Google wants to create a culture that emphasizes creating good products not at the expense of competitors.

I've never felt inhibited about having conversations with employees about these issues. The fact is that most of the employees I've discussed these issues with don't think Google is violating antitrust regulations.

My personal opinion is that a certain segment believe that Google should just be broken up because their data collection practices whether or not there are any real antitrust violations and just see this as a tool to accomplish that end.
Ask HN: Instead of COL, should salary be a function of PPP?
Where PPP is purchasing power parity. I've seen lately discussion here about how COL is an underfitted model for adjusting salary based on location, mostly because certain goods (e.g. a Macbook) cost the same no matter where you are in the US (or whichever country your company is based, I guess it is more complicated if you are an international company). I wonder if PPP would be a better model for salary, and immediately it seems that there would be less disparity in salary between e.g. SF and a random rural town, because after accounting for rent and food, most other expenses are equal.

Finally I think a better question is, should salary even be adjusted within a single country?

You're absolutely right. The idea that a corporation's board would decide collectively what political stances to take is not groundbreaking. However this kind of critical thinking seems to be so rarely applied to organisations trafficking in information, such as those making up 'big-tech'.

I was speaking elsewhere on Hacker News recently about how the attitude towards trusting corporations seems to have shifted so dramatically. Distrusting the motivations of large corporations was once a pillar of liberal thought in the west. Now many liberals seem to be willing to empower these corporations absolutely as long as they control online discourse in a way that largely benefits the liberal establishment.

I would encourage people to consider for a moment the financial incentives for organisations at the scale of Facebook, Google, Twitter et. al. to support globalist political agendas. This isn't 'conspiracy theory' thinking, it's shareholder primacy, it's simple politics. Anyone who thinks that these organisations support liberal causes out of the goodness of their hearts needs a reality check. They pursue these choices for their own gain.
HN / reddit / lobsters whatever programmer link aggregators may be astroturfed. But after a while you will learn to recognise the smell of astroturfing and even otherwise, they are refuted by commenters. More likely that there are fanboys that come with irrational arguments rather than astroturfing in these forums.

The greater harm of these content marketing bullshit is it pollutes Google search results. If you search Google for some mainstream enough technical terms, all you get is shallow information, poorly written, posts on bullshit sites.

I'd like someone to make a search engine for authentic programming related websites and blogs, even if hand aggregated. Instead of surfing through 5 pages of ZDNet, geeksforgeeks, DZone, thenewstack, quora etc.. highly SEO'd sites.

> The usual explanation is that the "first copy" arose randomly, and then kept going. Do you believe that?

I believe a variation of that.

I believe that the first copy arose through physical processes.

Evoking 'randomness' is unnecessary and misleading.

Do you not believe this?

To my knowledge, we don't yet have a mechanism for how such a molecule came in to being (though there are ideas).

We also don't have any reason to think that it must be some random single choice from a large possibility space, and we don't have any evidence at all that it could have arisen from non-physical processes (what would that even look like?).
probably not but some can kick in later in life too. theres a cheap "sweat salinity" test they give to newborns a doctor can do to rule out a family of such things.

That's utterly awesome and I hope the links didn't come across as "this has already been done"—quite the contrary—the intention is just "here are cool similar things if anyone's curious". A hexagonal version is a noble and clever addition!
The point of the article is the claim that Google wasn't so extreme about this before. If true, this means that they're seriously concerned with the ongoing anti-trust probes, and don't see them as something that's likely to go away.

I'll admit this article describes a much less bad system than what I envision when someone mentions compressed air energy storage.

On a side note, I wonder what the state of research is on reducing the embodied energy in li-ion battery production. The mentioned figure in the article is surprisingly high (2-10 times the total energy the battery will store - presumably they mean over its lifetime), which now that I think aboute it, squares with what I have seen elsewhere on the embodied energy of electric car manufacture.
I am always surprised/disheartend by the amount of people in threads regarding this topic who are quintessentially "pro-death".
dev.to and itnext are in the twitter thread thanking the poster for bringing this to light as if the existence of accounts that do this isn't a major boon to their platforms. dev.to and itnext, just like medium and other such sites are essentially content marketing farms. It is possible that they both dislike that activity and benefit from it, but I couldn't read those tweets without some skepticism.

I for one find that most really high quality blog posts I read are not really on medium/dev.to/itnext, unless some large organization has committed to making every employee post there, but rather on small blogs run by people who pay the $5/month or year or whatever to run their own blog. Maybe I just haven't looked around enough.
Well, okay. You said you hated "fan noise and excessive heat", not "spending money". I'm just pointing out that this isn't a reason to avoid a fast, x86_64 computer.

That said, I'm sure there are many modern laptops for a fraction of the price of a T480 which will do the job just as well, and a lot better than a Pi4. What is "minspec" anyway? You have to draw a line somewhere. Should I expect to run a modern DE on my smartphone from 2011? How about my desktop from 2005?

That said, by the spec sheet, those machines should be easily capable of running Plasma. If you're having problems, perhaps it's not Plasma's fault, but something to do with the blobby GPU driver stack?
Obviously HN readers are going to want to see the emails and decide for themselves. There's zero implication of authenticity (or inauthenticity for that matter). The only thing we care about at our end is having an accurate article (and headline) for the story.

Politics isn't completely off-topic for HN—there's overlap and it depends. There's lots of previous explanation about that at https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so..., and if anyone has a question that isn't answered there, I'd like to know what it is.

We turn off user flags sometimes when a story contains interesting (in HN's sense) new information and the probability of a substantive discussion clears a certain threshold.
