a) Who says we need seasonal storage to begin with? This is not something that has significant usage.

b) Anything. Anything is better for seasonal storage. Methane, pumped hydro, molten salt, flow batteries, etc... all of those are existing, or viable right now, not in some fantasy future where we all have fusion-powered flying cars.

c) The free market tends to take care of such things. Power is a fungible commodity. If electricity is seasonally cheaper, it'll just be used by industry for power-hungry processes such as smelting aluminium or titanium. You can then store those end products by simply putting them in a pile.

In a renewable-energy future, it would make sense to use electricity when it is cheap to make hydrocarbons that require its physical or chemical properties, e.g.: to make industrial chemicals, pharmaceuticals, polymers, etc...

We already know how to store hydrocarbons. You pour them into a simple metal tank. Easy.

We don't know how to store hydrogen. Still. After decades or research.

You keep mentioning hydrogen as somehow superior for long term energy storage when the opposite is true.

I've refuted each and every one of your claims about the feasibility of hydrogen storage. For the second time, you claim that my claims are invalid, without actually specifying what's invalid and why.

You claim to have explained why my criticisms are wrong, but you've done no such thing. In the more recent thread, you insist we have experience manipulating hydrogen at great scale. But I point out we actually have 2,000 times less hydrogen infrastructure. And I point out that 6% of natural gas production used for hydrogen production isn't all that impressive because most of it is used for heating, only a fraction of it is actually used in the steam reformation process. Explaining that our hydrogen infrastructure is orders of magnitude smaller than our natural gas infrastructure, you go silent. This hardly looks like a refutation.

If you want to actually refute any of my claims please do so. But you're just insisting I'm wrong without even bothering to specific what I'm wrong about.

>Literally nobody was buying that Iraq had WMD.

You must be very young, because this is totally false. Both political parties, every network and every newspaper was not only uniform in their belief and assertion that Iraq had WMD, they ridiculed and attacked everyone who denied this falsehood.

>Israel, Russia, Britain, China, and even France held positions similar to that of the United States; France's President Jacques Chirac told Time magazine last February, "There is a problem—the probable possession of weapons of mass destruction by an uncontrollable country, Iraq. The international community is right ... in having decided Iraq should be disarmed." In sum, no one doubted that Iraq had weapons of mass destruction.

https://www.theatlantic.com/magazine/archive/2004/01/spies-l...

There should be no doubt that disputing the official narrative on Iraq WMD would have been censored by Twitter and other big tech companies that use establishment narrative as the only benchmark for truth.

I had a similar experience with an open source browser extension on Google’s Chrome Store. The loudest complaints seem to be about Apple’s walled garden stores presumably because that’s where the money, but in my experience Google and even Mozilla seem to be more arbitrary in their policies/behavior. Googzilla tend to approve your app or extension and then a couple weeks later they start emailing you about various policy changes or policy updates or reviewer questions with arbitrary response deadlines such as “We will remove your extension in 7 days if you don’t send our reviewer a link to the README in your open source GitHub repo and explain again how to follow the instructions to build it. (Type ‘make build’!)

It would be nice to finish the review process before approving an app. If you have new policies apply them on the next review or ask your questions when a future update is submitted.

So the main thing that clicked with Brazil was really understanding how to use versionsets effectively to model software stacks and in particular thinking about a package's dependencies as part of its public interface.

A common anti-pattern I saw at Amazon was for some team to need some functionality, see a package in the "live" version set that had it, and grab it without thinking about how that package's dependencies aligned with their application's. Teams also frequently used the wrong dependency type (runtime, build, test). Things will "work" if you declare a test dependency as a runtime dependency, but you are setting yourself up for unnecessary version conflicts down the road (you can have multiple versions of a package in your test dependency closure, but not your runtime dependency closure).

As for what I missed at the company with the monorepo there were two things: The first was that there was no way to deploy a version of the code that was exactly the same as what was in production plus some patch. The deployment system could only deploy the tip of the master branch, so if you needed to patch in prod you were going to bring with it all the other changes that had landed on the master branch, for better or for worse. There is no reason that a monorepo has to have this problem, though, it was a limitation of the deployment system.

The main thing I didn't like about the monorepo though was that it was next to impossible for me to track the changes that were relevant to me. In Brazil, every package is its own git repo and it's very straightforward to just list the git history of a package and see what has changed. In the monorepo 99% of the change in the git history were completely irrelevant. Also, twice they needed to rewrite the history of the entire repo to expunge some secret that had accidentally been committed years ago. All the hashes changed and it was very disruptive.

So what's good about Brazil is that it gives you the advantages of a monorepo without all the source code literally being in the same repo. It's also good because you can maintain multiple versions of the same package together and migrate different consuming apps separately. What's not so great about Brazil is that there is really a subtle art to factoring your software into packages and version sets and most times you get it wrong in a way that leads to seemingly unnecessary pain. The fact that you don't have to update all consumers together means that its really easy to just not update consumers and you pay the price for that eventually. There's another big pain point with Brazil which is that it was traditionally difficult to import open source software from open-source repositories (NPM, PyPy, Maven, etc.). This has gotten much better in recent years and there are efforts to improve it even more.

Matrix is an open network like Email or the Web. So if you use a "free" server, it means you've selected a public server like matrix.org or privacytools.io or whoever. These servers are hosted philanthropically for the benefit of the overall network (e.g. Matrix.org's hosting is paid for via Patreon: http://patreon.com/matrixdotorg).

If enough organisations run their own servers and make them available to their users for free, then you could indeed support the online billions. Instead, much like email, we already see a mix of free services (the equivalent of hotmail, gmail etc) and paid services (the equivalent of g-suite, protonmail, etc).
> Literally nobody was buying that Iraq had WMD.

(real question) Why is transactional email considered a cesspit?
I think these measurements include the page table entries in the kernel? It's my fuzzy understanding that page table entries are 64bit on amd64, so if you have 64GB of shared buffers (which is quite a lot) you'd have 128 mb overhead just to map that with 4kb pages. Which is to say the overhead is proportional to both the shared buffers size and the page size.

It is not a constant factor. Saying it is about 2mb is misleading.

It's possible I'm missing something special about postgres, but that's how shared memory between processes works on Unix systems in general.

MySQL uses threads which are much lighter weight because they don't need their own page table entries, and they don't need to do as many TLB flushes when switching contexts between them. It's one of the architectural decisions they did right I think. Postgres went with processes so it's easier to kill a connection cleanly, without leaving a things in a bad state. I think there are other ways of solving that problem though.

Stop that apologist crap. I grew up in a rural area and I know these people quite well. People in rural areas reject science, general knowledge and social norms of the "big cities" because they are frightened and ignorant, not because of some equally valid world view.

Their response to climate science is stubborn ignorance. Their response to different cultures, races and religion is bigotry. Their response to democracy (when it doesn't suit them) is reactionary. Their response to education is closed mindedness. There's nothing to respect here.

Rural people are happy to have iPhones, as long as they don't need to understand the science behind the technology, understand the multicultural aspects of it's existence or respect the people who created it.

As Asimov said 40 years ago:

"There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that my ignorance is just as good as your knowledge."
"ProtonMail says that Apple forced it to monetize its app".

I stopped there. I have seen a lot of articles like this misleading the public about the issue. Apple didn't force them to monetize anything. It was monetized. Apple told them to use IAP or don't direct to your own payment system in the app.

Either these journalists aren't capable of doing some basic research to understand the issue or are outright trying to deceive the public. Either way is saddening.

Another deceiving post:
https://www.theverge.com/2020/10/8/21506995/apple-forced-in-...

Edit: I see a lot of downvotes. Don't downvote! explain how is this "forcing to monetize". Webster dictionary: monetize - to utilize as a source of profit. Forcing to monetize means the app wasn't selling anything and Apple forced them to sell something. This is not the case! Apple forced them to choose between using IAP for payment system instead of their own system OR don't direct users to external payment system from within the app.
Another concern with Vit D supplementation is magnesium.

As calcium and magnesium compete for absorption, Vit D’s effect of increasing calcium absorption can reduce magnesium absorption and lead to symptoms related to magnesium deficiency.

I gather the toxic effects described in the article are partly due to extreme magnesium deficiency along with other effects - though magnesium or other effects aren’t mentioned in the paper, only acute toxicity symptoms.

But it can be an issue even at much more conventional levels of Vit D supplementation, as many people are already magnesium deficient due to it being difficult to absorb from foods.

As I’ve had evidence of Mg deficiency, I’ve been taking magnesium malate for a while, but am now looking at the more absorbable forms magnesium l-threonate and magnesium bisglycinate. At times I’ve taken a supplement that combines calcium, D3, magnesium and phosphorus, to keep these nutrients in balance.

Of course one should work with a health professional when considering taking dietary supplements.

The hard part would be talking to it. Voyagers have the highest path loss of any communications link, over 300 db. NASA uses 70 m dishes. We can assume that they have cut the transmit power (or raised the data rate) as much as possible, so you would also need at least a 70 m steerable dish, or more if you don't have NASA quality low noise amplifiers. I don't know what one of these costs, but the one at Goldstone weighs 3000 tons so you probably can't afford it.

The Russians have a couple 70 m dishes, so your best bet might be to make friends with someone who works at Yevpatoria or Galenki.
I am wondering if this is really a problem? I just parallelized some numerical code and instead of threads (Gil problem), I use processes. As far as I understand the only drawback would be that the parallel items cannot share memory, well do you do that? I find it hard to reason about correctness in these cases.
>actually Orwellian phenomena

This isn't an Orwellian phenomenon. This is just the typical bad reading of Orwell that Americans have tried to squeeze out of the book because of their free speech fetish.

The central key issue of the book isn't a big scary guy with a mustache stealing your newspaper, it's reality inversion, it's the inability of everyone in society to distinguish between what is real and what is fiction, which is the basis for, not the consequence of totalitarianism. It's the moment when someone blatantly tells a lie, and everyone eats it up, when the world starts to feel unreal and like a bad movie.

The real Orwellian phenomenon is not some kind of scary gatekeeper separating truth from fiction, which is actually a productive use of authority and necessary in any civilisation that doesn't want to turn into a clowncar. What's Orwellian is people going to Facebook, reading blatant lies and untruths, and being unable to distinguish that from what is real. And that is actually caused by the disappearance of gatekeepers, who play a vital role in maintaining liberal institutions.
