Just as burning fossil fuels cause dangerous reconfiguration of earth's atmosphere, I think that the idea of a hydrogen economy requires careful thought. Hydrogen shares with helium a unique property, that it is at escape velocity at the temperatures of the upper atmosphere. It seems unfathomable now, but if we converted all earths water into hydrogen and oxygen without containment, the planet would become a dead rust ball. It's not that these technologies should not be pursued, merely that adopting any technology on a planetary scale, should require some incredibly serious consideration.
Makes sense, and thank you for writing this out! It's useful to think about when someone offers equity instead of a higher salary.
I get the cheaper combo plan of the provider with best local coverage and very rarely exceed my quota. Most of the time I use less than 25% of it. I'm on Brazil. Can't speak for everyone but I see similar cases distorting the data.
Biochemist here. No it is not, and that's not epi-101. By letting it rip you're not just maximizing your fatalities, but you're also maximizing the rate at which the thing mutates, which maximizes the probability that your "recovered" pool becomes vulnerable again.
I definitely agree that gravity, some sort of ecosystem, probably some kind of atmosphere, and a source of heat are needed in any case.

The idea of "stone age" tech being enough to survive implies an ecosystem that maintains itself.

A rogue planet could have heat and water if it was reasonably large or part of a multiple body system with tides. C.f. Enceladus and Io. Then there's Titan.

A film I really like on this topic is Class Dismissed. It shows the journey of two girls who leave school and it's really amazing to watch them relax, get more at ease with themselves and make friends over the course of the film.
It is a good insight indeed.

As a fan of Henry George, I think the greatest trick pulled in economics was rentiers successfully getting Smith's concepts of capital and rent to be lumped together as "capital".
This would only be relevant when the fuel leaks, right? During normal combustion the hydrogen is never exposed to the open atmosphere, it is burned back into H2O and released in that form.
I have a tangential question. What is most people's experience with additional options being awarded to employees beyond the initial grant?

Is there generally also a separate cliff for those additional option grants?

I ask because I interviewed with a startup recently and the recruiter told me that the company had just awarded everyone in the company additional options. I asked them if there was a cliff attached to those but they couldn't answer that.

As already said, the problem is in coordination of multiple telescopes in spacetime.

It might be better to build one giant telescope piecemeal, by adding more and more small mirrors. A similar approach is taken by several terrestrial telescopes.

It would still be very interesting to have a few space telescopes distributed across the Solar system, much wider than the Earth orbit. It could give a sort of stereoscopic picture of closest star systems, even though "simultaneous" observation would be ill-defined for them.
I do something similar and I just have one question for you. How do you not tire of the constant context switching and "being in the weeds" of multiple client projects?

There isn't a paywall I can spot in the original link - perhaps it's a regional thing?

What you might be missing here is that the "only downside" should be emphasized far more. Hydrogen is a bloody nightmare to store long term. It's boiling point makes the -20 C involved with this technology look like an oven and you really do want to ideally store it as a liquid since the exceptionally low molecular weight means leakage is a constant problem save for some very advanced (and expensive at scale) carbon composites.

Graphene seems to be a potentially excellent storage medium but we are still a while off from being able to manufacture that at the amount that would make it economically usable for hydrogen storage at scale.

Probably one of the most subtle things about this whole bit that I've only now noticed is that George takes 4 buns out of each pack of 12, but gets 3 packs.

I enjoyed this article, but I’m confused. The section raising the question about how this has affected other asset prices seems to just posit the question without establishing how the banks actions would have done so. Is there some obvious link between the FED buying mortgage backed securities and technology stocks going up? Or should it be inferred that by buying those securities they just put more money into the system that is creating the situation they describe? Thanks for any explanation.
Every year friends launch their float planes from the International Airport in Whitehorse, Yukon.

All the float planes are out of the water for winter freeze up, put on trailers. So in spring when the ice is gone you get a friend to drive down the runway full speed towing the trailer and plane, then take off directly from the trailer - there are no wheels on the floats and taking them on/off is a pain and not worth it.

My friend said it's always a little scary trying to remember how to fly for the first time in 9 months while being pulled behind a pickup truck at full throttle and around 180km/h. Because it's not tied down, he said if you're not on it, the plane just falls off the back of the trailer onto the runway - not good.

There's essentially a couple of days in spring when all the float planes around town do it, and a lot of fun to watch on a runway that has daily international flights around the world.
It's also a smart marketing campaign
I feel everyone replying to my comment is missing the overall picture.

YouTube has content guidelines... that doesn't mean they are obligated to enforce them, it only means they have easy reasons to moderate content where they feel like it. Their only real interest is profit, generally through showing you ads (by keeping you glued to the screen, sometimes by showing you controversial content) and by harvesting data. I'm not saying that's "right" in a moral or ethical way, it is simply the truth. If you recognize that, then it doesn't matter that they are recommending videos that ostensibly violate their own terms, and arguing otherwise seems to make you just willingly ignorant. YouTube has no incentive to incorporate "regrettability flags" into their algorithm, except to the degree that it serves them.

I'd go further to say that YouTube probably could do a better, more thorough job of cleansing content on their platform, without any additional cost. But having a certain amount of content that is controversial, which panders to a vocal minority, etc actually serves their platform. They use the 1st amendment sometimes to justify this, but they actually don't care one bit about any of that. All they care about is money, and at this scale the dynamics get kinda interesting.
Libre games don't have these issues.
Yes. But one should be aware that leaking some hydrogen is leaking it to the outer space, for good.

This realization does not stop us from using much more rare helium in party balloons, though.
Thank you, I was not aware that natural gas generation was so inefficient.

I wonder how from a pure greenhouse gasses perspective, the numbers stack up. I know that leaked methane is much worse than CO2. 28x according to [1]

This source [2] says that the grid looses: 2% - 5% of gas between provider and consumer.

Even assuming that your grid is 90% just gas plants stil.

30% loss at the power plant, 5% loss from electrical grid. So for every unit of water heated you are wasting 35% of the energy.

Vs say 2% loss in the natural gas grid. but that 2% is 28x worse than burned CO2.

Am I completely wrong in saying that from a pure this hurts the planet more electric based water heaters often probably still win?

As a Sri Lankan it breaks my heart whenever this type of topic is brought up, the amount of damage colonizers including the British did to my country, my culture is just heart wrenching.

How the British and other colonizers go unpunished for all what they have done not just to my country, but to so many other countries in the past is just unbelievable.

But on a more positive side, more and more Sri Lankans are starting to realize what's missing and are actively trying to bring back some of the knowledge and wisdom that was lost all those many years back.

If the lockup is 180 days, you can wait for a pretty long time before exercising. It's usually halfway apparent when a startup beings IPO readiness.

What gets you with waiting, if you have ISOs, is how much AMT hits you. If you're at a >50% IPO company, it's somewhat common to exercise as many options as you can before the AMT hits you.

It's also worth remembering that your 50% startup could be Wework. It's worth $9B, but was valued at almost $47B.

I'm excited about anything in electrolysis/fuel cell development, but the figure of merit is efficiency. It's neat to use sulphuric acid to reduce the freezing point of your electrolyte solution, but if it's not efficient you might as well just heat your electrolyzer.

Nothing is a power system without efficiency figures. Otherwise it's just a chemistry experiment.
Meh. Tracing over drawings isn't that bad.
A civilisation capable of significant depletion of the earth's oceans for the production of hydrogen and oxygen is so far ahead of us in economies of scale that we would be long past the point of needing to worry about something that could (to the point of view of such a civilisation) be trivially solved with an air wall or a secondary low earth orbit artificial magnetosphere.

> 1) It’s not clear that market making is all that necessary or desirable with homes. Homes are not stock shares.

I think it's pretty well established in economics that market making improves liquidity. As a parallel, in the used car market, having used car salesmen allows people to quickly liquidate a car to cash without needing to go through the work of finding buyers. Similar on the sell side.

And the housing market is one very sorely needing liquidity, as even the quickest closing times take 30 days, at the cost of a 5-7% spread amounting to an average of $25,000 wasted on middlemen.

The sheer amount of hydrogen you would have to put into the atmosphere for this to become a problem is enormous.

This is a problem in the same sense that the sun going red giant is a problem.
>Facebook is issuing a cease and desist to my favorite Chrome extension: Unfollow Everything

This thread doesn't answer "how Facebook tries to kill it" but might answer "why"

Without seeing the cease and desist it's really not possible to assess this. It could be that Facebook is overreaching or it could be that he copy and pasted proprietary code. We don't know.
It's worth pointing out that hydrogen oxidizes in the atmosphere, unlike helium, so it won't escape as readily. Secondly, the Sun already splits water into hydrogen and oxygen with UV at some low rate, and that has been going on for literally billions of years from now. I don't think this aspect of what you're talking about will matter before 200 million years from now or so when the Sun becomes intense enough to kick off runaway greenhouse effect (even without human effects) unless we produce so much hydrogen (and leak it) that waste heat of civilization becomes the limiting factor.

There are other things to worry about.
I don't really care about service size. I care about service division across logical boundaries, namely encapsulated responsibilities. A properly architected service should be responsible for a particular domain, say payments, messaging, image processing, etc.

It's up to each team to decide where to draw those lines. I think that for most teams, domain-specific services are superior to task-specific microservices, since it strikes the best balance between the benefits of separate services and the infrastructural overhead required to run a distributed system.

That said I agree that you should start with a monolith.

In my experience, Java and Rust have the exact same problem. The nature of the dependencies is different, though; in Rust or Java, you'll have dependencies that handle a protocol, set up something like TLS, manage state, that kind of thing. In Javascript, you'll have a single dependency that provides a single function that does a recursive file search, or a dependency like is-number that checks if a variable is a number.

Javascript seems to prefer millions of tiny dependencies of thousands of larger libraries, which is a choice that can be defended. The difference is not necessarily one in lines of code or binary size, but one in amount of vendors trusted. Many libraries also handle trivial code that (in my opinion) should be part of the programming language or basic developer knowledge already. The is-something packages that fill Javascript dependency trees to the brim can only be considered as failings of the language in my opinion.

As a developer, I trust parties like webpack, gulp, and Facebook, but I haven't heard about jonschlinkert (nothing against him, just a random name I picked) and I don't know who maintains is-number, is-path-cw, is-path-in-cwd, is-path-inside or path-is-inside and how reliable they are. All of these dependencies seem like excellent methods in a library, but they all could've been part of a single dependency no more than 60 lines of code in length. Many NPM packages feel less like libraries and more like automated StackOverflow answers. Adding a vendor to your supply chain for just 40 lines of open source code is just inefficient; why risk trusting yet another vendor to not inject malware in the future like this?

The Java world has some popular names like Apache, Google and Jetbrains that maintain large libraries so it's easy to build a chain of trust. Rust is moving the Javascript way, with hundreds of megabytes of dependencies from thousands of individual repositories, but at least most of its packages add something nontrivial.

C++ doesn't have a package manager, at least not in the same way other languages do. C++ libraries usually come from very specific toolkits or single sources (like Linux package managers). There's tons of packages for C++ development, but all of them are kept up to date by a single organisation on my machine.

Once we have enough fascist governments, expect war, because fascism and war go together.

That's not really true. Hydrogen oxidizes in the atmosphere, whereas helium does not. Also, helium is continually produced via nuclear decay in the Earth, and it seeps up through the crust. So it's rare and it leaks into space with or without humans.
Losing Earth's hydrogen to space would require a stupendously long wait. Maybe freeing all of it at once would help speed the process asking, but the first lightning strike, volcanic eruption, or meteor would just ignite it all back to water. I'd be far more worried about getting struck by lighting, a volcanic eruption or a meteor, than losing our hydrogen to space.
I think you should look at plots of CO2 emissions over time. Life is very efficient at exploiting resources in an exponential fashion, when they become available.
One way to store hydrogen safely long term is metal hydrides. Hydrogen readily infuses certain metals, like lithium, like water infuses a sponge.

The problem is that the density us rather low. Enough to store tritium in a nuclear warhead, but possibly a bit bulky for home use. (Also, the hydride remains flammable.)
Phone cameras don’t have multiple lenses working together that you can interpolate between to create a single giant virtual lens. The technique OP is referring to is already used for the largest ground based radio telescopes.

NixOS with nixops is one such option (on bare metal or VMs).

You need to climb up the Nix learning curve a bit, but obtain an overall vastly less complex system than Kubernetes with its millions of lines of code and various levels of OS and networking encapsulation. It is possible for a single human to read and understand all code involved in a nixops deployment in a few months of side-time reading. It is possible to debug operational or configuration issues easily, with standard tools, and standard Linux systems understanding.

You manage your entire infrastructure, including all software and how to build it, declaratively. If you use cloud VMs, nixops will also create them for you.

It is not as powerful as Kubernetes; for example you currently don't get fully automated rolling deployments that roll back if your health checks start failing; you need to do this yourself e.g. running `--include machine1` through `--include machine3` to do a rolling deployment. However, this is often fine, as most small to medium teams do human-triggered deployment (and ensure that it works as expected) anyway.

I found that this works very well for small to medium teams that want to spend as little ops overhead as possible, while still understanding their stack entirely.
