Michael Liebreich's clean hydrogen ladder is a good reference here: https://www.linkedin.com/pulse/clean-hydrogen-ladder-v40-mic...

It ranks hydrogen use cases by their economic feasibility. The core issue in Japan: they are focusing on things with the least economic potential at the bottom of the ladder and they are doing it with dirty grey hydrogen even.

It's a double fail. Basically they are expending more carbon to magically become cleaner. Which isn't working for obvious reasons and quite obviously so. And then they are using that hydrogen for the least economical use cases. It's not an energy strategy but a let's bail out our car manufacturers strategy.

This article is stating the obvious: this isn't working. Not even a little bit. There's nothing there. Hydrogen cars are a fantasy. Nobody is buying them and even the world's largest hydrogen cheer leader (Toyota) of these things is barely producing and selling any. And as reluctant as they are to produce and sell battery electric vehicles, they still sell more of those than hydrogen cars.

Hydrogen for domestic use also ranks at the bottom in the hydrogen ladder for very good reasons. Yes you can do it. But it's just stupidly inefficient in terms of hydrogen generation and transport losses.

These are not problems you can just wave away with some innovation magic. There is no magical solution just around the corner that will make all of this go away and improve things by 10x. The issues are pretty fundamental and have to do with hydrogen just having a very low energy density by volume (it's the first element in the periodic table), energy conversions having a cost (second law of thermodynamics), and the bonds between hydrogen and carbon or oxygen atoms being very strong.

It takes more energy to break those chemical bonds than you get back in the form of hydrogen. There's a theoretical maximum efficiency to that. Once you have hydrogen, you have to convert it again to do something useful with it. That too has a maximum theoretical efficiency. These inefficiencies multiply. What happens if you multiply two fractions? You get a smaller fraction. Compressing and cooling also takes energy. And if you introduce conversion to ammonia or some other susbtance, that's another conversion, which is lossy. That just multiplies the problem.

So, that means hydrogen should be prioritized for those use cases where you can minimize the losses. Anything involving transporting hydrogen over long distances is a problem. Because of the volumetric density. It's just not very efficient. You need to move a lot of volume of it. And it's a tough substance to contain. Leaky valves, boiling of liquid hydrogen to keep it cool, etc. The losses accumulate rapidly. And even when you contain that, you need to ship about 18x more of it in compressed gas form to match a single tanker of petrol or about 3x in liquid form (cooled to near absolute zero). Compression and cooling take energy btw.

Because of all that, the vast majority of hydrogen produced right now, is produced and consumed on site. Mostly for things at the top of the hydrogen ladder like fertilizer production or use in various chemical processes.
I’m curious how the calculations work here. I know that any individual battery electric car is better in terms of GHG emissions than any individual hybrid car. However, given the limited number of battery electric cars, and the limited production, battery electric cars will remain the minority of all cars at least until the end of this decade (probably even longer). Now my question is, en masse, since the production of hybrid cars are a lot more capable then battery electric, are we not better off (in terms of total GHG emissions) with as many hybrid cars as we could get? That is, don’t hybrid cars shave more GHG emissions just by the shear number of them?

Of course I believe this is a moot question because we could save way more by focusing on public transit, and simply have fewer cars. After all: battery electric are more efficient than hydrogen, which are more efficient then hybrids, which are more efficient than ICE but transporting 20 people in 15 battery electric cars comes nowhere close to the efficiency of transporting these same 20 people in a single ICE bus.
More lies and more deception:

Japan has huge deposits of methan hydrate on sea floors it wants to mine.https://de.wikipedia.org/wiki/Methanhydrat

And this is why hydrogen is on the shit list, all the roads lead to ever more mined carbs, blown into the atmosphere in one way or another. The roads to green hydrogen are riddled with conversions that make it economically unviable.

Its the equivalent of a addict switching from heroin injection to a fetanyl patch. Yes, the process is cleaner, less dangerous, but the longterm bad effects are still there.

Unfortunately, Harrison's book, despite its many other merits, doesn't really treat CDCL (= conflict-driven clause learning), which is really what makes SAT solvers fly.
So it is not a next generation editor at least yet? I personally do find this kind of marketing language off-putting – if the main promise is basically a false one, I immediately get suspicious of the whole product in general and dismiss it without even trying it out :/ I would rather read a honest "simple to use" even it is not that loud or unique.

You might mean something like if you restrict the set of all valid inputs to N characters then the language is regular, but that's a much stronger condition than requiring the input to be finite. Furthermore, such a restriction makes the language non-recursive; it's effectively a trivial language.

In standard automata theory, all inputs to automatons are finite.
You're using "being named" in a very unusual sense. Most people would consider you not to have named something if you're literally never allowed to stop speaking (or writing) the name. Most reals "have infinitely long names" under your definition, and there is no finite time at which you've distinguished between reals with the same initial segment of "name", so really what's the use of the naming scheme at all?

(For a more compelling argument, the equality of real numbers is uncomputable, so it must be impossible to name them. If we could name them usefully, then we could determine equality by asking which ones had different names.)

I can already smell the parallel arguments for not stopping hunting whales for fuel, continued use of lead paint and asbestos, whining about freon, and the health "benefits" of tobacco.

Ban ICEs now. The sooner, the better. They're an unsustainable threat to our survival, excess death-causing, petrostate-supporting cancer that we can already replace with clean EVs now.

Those against rapid decarbonization of economies are delusional, suicidal, sociopathically greedy, or stupid because there's no rational evidence to counter the hard science of reality.

I ran a consultancy for 15 years before selling it. Was at times fun, and certainly educational, but would I do it again? Unlikely.

Anyway, couple of things that worked for us:

* Try to get retainer contracts: we would offer one when we had delivered a project. This is great for you as it makes income more predictable. And it is great for the client as they know they have certain capacity from you, and don't have to go to their boss with a new budget request for every small thing they want changed

* Don't let a client grow too large: we had a big client that wanted to buy all capacity we had to offer, and wanted us to hire more for them. We never let them become more than 50% of revenue, so we were able to survive when they went away one day (the "burning platform memo"). Keeping them at 30% would've been even better, but it is hard to say no to money

* Don't try to be fancy: you're not one of the big consultancies, so don't emulate then. If clients wanted that stuff, they'd deal with those companies, not you. Our sales conversion rates improved radically when we switched from tailored suits to jeans and conference t-shirts

> Hierarchies are heavily part of human behavior.

I think the tendency to follow is part of human behavior. The tendency to fight against others telling you what to do is also heavily a part of human behavior. We clearly have both aspects to our nature from a very early age.

There's a lot beyond the tendency to follow that I think of when I read the word 'hierarchies', so it's not clear how strong a claim you intend to make here.

> The concept of leaders and rank is so ingrained in behavior it's hard to think it didn't exist even in hunter and gatherer societies.

Rank, leadership and authority are different things. I've read accounts of rank and leadership without authority, of leadership without rank, of rank without either leadership or authority, of authority without rank (when executing the decisions of a tribal council), etc.

It is indeed hard to imagine that any society didn't have acknowledgement of expertise or impartiality and a measure of deference to it in its own sphere (therefore leaders), and even in a 'egalitarian' society there would be differences in wealth, family size, influence (and therefore 'rank'). But that doesn't necessarily mean a full throated 'hierarchy', at least as I would use the word.
Omg. My childhood is back. The Sims was one of my favorite games of all time. I would spend so many nights playing this game until 4 or 5am, using the free money cheat to trick out my houses and to set my Sims up in horrific situations. I would then have to be up to leave for school at 7:30am and try to explain to my mom why I was so tired, not dare telling her the real reason, lest she remove my PC from my bedroom.

I even used to use my miniDV camera and the FireWire card on my computer to capture game footage to edit it with funny voice overs and edits, similar to the style later known as Machinima. But it was the year 2000 and I didn’t know anyone else doing anything like that.

The subsequent games have been varying degrees of great or meh — Sims 2 was a disappointment to me and while it took me a while to embrace it, Sims 4 is pretty dope (I had very few complaints about Sims 3). But the first game, I remember reading a preview of it in Next Generation magazine in August of 1999 and getting a preorder at my local video game store that week. Six months later, I left school early to get it early.

I can’t wait to play this when I get back home tomorrow.
Slightly tangential, I've tried using various Pomodoro apps on iOS, and none of them seem to be able to alert me when the phone has turned the screen off. Is this an iOS restriction? I can imagine that apps are restricted when not in focus, and even more so if the phone is not being used at all. The only app that can raise an alert is the built in iOS timer, which honestly does 95% of the job, so I use that instead.

There is no second earth and there's no time to waste on the tranquil soma of gradualism, denial, and delay. Delay will be measured in millions of avoidable deaths, if not billions.

If you want that on your conscience, by all means, keep drilling, burning extracted fuels, and adding carbon to the atmosphere.

"Merchants of Doubt" - a book, with a website, about the topic of a tiny subset of shills and crazy people in "scientific" fields who have stood in the way of ending such hits as DDT, widespread smoking, ozone depletion, and, of course, climate change denial[0]. It's always the same pattern with them: deny, distract, trivialize ("It's not so bad"), equivocate, delay, calls to "slow down", and be "concerned" that not spraying DDT on kids at school "will harm the economy".

The most literal English translation that is yet still readable English is the New American Standard Bible. ESV is very good, too, but at some times is more "literary" than literal.

If you want more literal, you might try the American Standard Version, which never gained much traction but it's a good formal, if older, translation.

Hey that’s a useful feature indeed, and it can already be added by the user with rcmd’s Window Actions which support AppleScript. I actually have done that myself already for Firefox.

It's not new as you could think after reading the article. I remember reading about this technology - seeing humans through walls basing on internal wifi signal for some US government agencies - at least 7y ago. Also OpenWRT software for routers has plugin for gestures for MANY years already. Possibilities of reading gestures by your home router implies all mentioned use cases.

It's past, but written here as a future. It's truism but written as discovery.

Another truism would be saying that it scales for any radio antennas - like GSM. Especially if you have dense grid.

Carbon capture is hard, nitrogen is truly abundant. That is unless you happen to have a source of highly concentrated CO2 at hand. Which is certainly true now, but won't be in the endgame. Methane (or something with an even lower H-per-C) will surely be part of the picture, but it can't be the mainstay. I'd expect hydrolizer capacity to cluster around storage opportunities (like salt caverns) within convenient grid range from energy sources, large ammonia plants to continually work from that hydrogen buffer and higher-value H2 consumers to opportunistically tap into the same buffer whenever their "other ingredient" is available. That "other" could be metal ores, iron oxide returning from an oxidization energy cycle or CO2 from biomass burning or waste incineration. But there's always hydrogen as a first step, and the (centralized within grid range) hydrogen storage as the buffer that solves the dispatchability problem.

Fun observation: If some of the hydrocarbons created this way make it into plastics that isn't passed back into incineration (or a better form of recycling) you'll have true carbon-capture for the fraction of the carbon that came from biomass. Without we trying.
Not to say that it’s all rainbows and daisies.

Part of the guilds’ power is that they have rules and agreements with the other unions that disallow using non-union labor if other union labor is involved. Or if certain rules are broken. Bargaining is much more powerful when the actual product cannot be shipped if the unions strike or don’t work on your project. Software does not really have this restriction.

And as someone who also has many friends across various roles in the Industry (and once tried to break in), there is one not-oft talked about downside: it is rather difficult to get into the guilds, with a lot of unpaid internships and nepotism involved. And even with the great union contracts, hours are long, the work sometimes dirty, and the culture on set often times incredibly toxic.

So yes. The guild model probably the one that is more applicable to SWEs. But also don’t copy the model Hollywood has built too closely.

My father & mother divorce since I was 5, and I live with my mom since. One day we have to go to funeral of our relative, and my father is there. We are complete stranger by now, but also father and son. So imagine when I have to talk to him, for the first time after 30 years later. It's awkward as hell, but I'm glad I decide to do it because that might be the last time I have a chance to speak to my father. It's small talk and nothing more, yet I can feel something heavy lift out of my chest, like, he's just an old man now, and whatever bad things he's done in his past is now long gone — it's like I'm reconcile with him in some way.

That being said, I don't have answer for you, but if you think you should do something about it, then do it!
