(Shameless promotion: if this stuff interests you, check out my brand-new course https://www.terra.do/hydrogen-economy)

There is a developing consensus that in order to get to "net zero" by 2050, hydrogen will need to be a significant part of the energy mix. For example, here [1] are two forecasts that predict H2 will account for ~10% of global energy use. This could just be dismissed as "hype" but across China, Europe, and elsewhere, real money is going into electrolyzers and fuel cells (at, I dunno, 500% YOY growth?) which I think is why stocks are acting as they are.

Here's a list of where H2 fits in, and other sustainable alternatives. (Of course, for all entries, "indefinite fossil fuel usage" is an option in some sense!)

Current H2 usage. Fossil-derived hydrogen is a cornerstone of the economy (for eg fertilizer), and responsible for a few % of global GHG emissions. Replacing that with low-carbon-intensity hydrogen would be a major win by itself. Kind of by definition, there are few alternatives here.

Other industrial uses. The production of steel, plastics, etc are complicated systems, each too complicated to explain here, but eg HYBRIT [2], a fossil-free steel plant, could reduce emissions from Nordic countries by 7-10%. I have not heard of many alternative decarbonization pathways here.

Non-passenger-vehicle transport (trucks, ships, planes, trains). Molecular fuels have higher energy density than current-gen batteries by 1-2 orders of magnitude. I predict that these vehicles will mostly not be battery-powered. Biofuels are another prospect. "E-fuels" (sourced from H2 and an atmospheric carbon source) are another.

Lots more. Intermittent renewable valorization, building heat, power storage, gas pipeline admixtures... but this comment is already too long. I also like this story [3] about the Intermountain Power Plant, the largest H2 project in the US that I'm aware of.

Thanks a lot! Do you find it hard to understand how the app works?
Did people vote for this? Doesn't look like he campaigned with this in mind, is it really democratic to just randomly put together things like this?

Interview with an ex-climate change denier
"objectively obscene or extreme" - is there a clear definition for obscenity? I feel like there was a famous quote from a judge on the SCOTUS to effect of "I'll know it when I see it", but law is not an area that I have expertise in.
This is what I don't get. Why not just make your browser window narrower? Wikipedia is one of increasingly smaller set of sites which have the decency of NOT WASTING MY FRIGGING SCREEN SPACE by putting text into a narrowest of columns in the middle of my screen and leaving the sides empty.

I get that line scannability is an issue for some people, but that's why _you_ can adjust the way _you_ read the article on _your_ device, without affecting _anyone else_. Web browsers, and desktop environments in general had this magic window-resizing ability for decades.

At least there are cool browser extensions like CustomCSS, which allow me to fix sites I visit often. I guess I will be adding Wikipedia there soon... :/
That's smart, I'd probably just play with it on my computer, since testing code in production is my life's motto.
Also good to see that they have written and published Clojure specs for it. Makes it easy to understand everything at a glance. https://edn-query-language.org/eql/1.0.0/clojure-specs.html
Seeing Barr on the proposal makes it look DOA. He also wanted to mandate compromised encryption for everyone's security benefit.
I have faith in Knuth, but he's an extreme outlier.

The balanced binary tree is a rough one. But checking that a tree is balanced would be a nice whiteboard problem.
taking a step back, openai is rightly concerned about potential abuse of gpt-3 and must also find a way to create sustainable, healthy revenue streams.

think of openai's work in three large buckets: (1) groundbreaking research; (2) preventing gpt-3 abuse; and (3) laying the foundation for an independent future.

put another way, there's a stark difference between doing research and commercializing research. openai must do both while carrying the additional burden of preventing abuse.

the angel's interpretation is that openai is outsourcing non-research, non-core activities to microsoft similar to how a developer might outsource customer sales and support to a MBA grad. this frees more attention and resources for research.

let's hope this is true, though i can understand many of the cynical viewpoints.

EVs and different chemistries based energy storage (Zinc air, LiFePO4, liquid metal batteries) will win first and hydrogen will help with curtailment issues of excess renewable energy for longer duration storage.
> Such designs and operation put our society at risk by: (1) severely eroding a company’s ability to detect and respond to illegal content and activity; (2) preventing or seriously inhibiting the timely identification of offenders, as well as the identification and rescue of victims;

To me, that says if a company writes something that prevents or blocks illegal content from being accessed by law enforcement, any immunity or protection is removed.

First question that comes to mind: How hard is it to build a web story from scratch in a text editor?
There is a lot of inertia behind it. Some companies will have thousands of ArcMap documents which need to be maintained.

And the ecosystem has value all on its own. No single product is the best. But taken together it is the least bad option. Particularly when you want the same team to be able to construct lots of fairly dis-similar pieces of technology.
Reddit has a subreddit that’s main purpose is helping you to shoplift without getting caught. I always assumed it was free speech laws protecting it. Does this mean there will be another incoming subreddit purge?
I don't understand Larry Sanger's complaint about NPOV. If a neutral encyclopedia was required to list all minority points of view on every topic then nothing would be knowable. It wouldn't be able to say that the earth is round. If saying that the earth is round is biased then neutrality is worthless and not worth pursuing.

Our entire system has been setup like this for decades. 99% of earnings have been going to the top 1% for decades now.

I understand people who don't want to get behind BLM - I might not agree with them, but I "get" them.

But the fact that the country looked at Occupy Wallstreet and collectively shrugged its shoulders and said "I don't see a problem here" - well, here we are - slowly building back a feudal society while blaming the poorest amongst us for our troubles.

Pre-industrial CO2 levels were 300ppm. In my lifetime I saw us cross 400ppm of CO2; I may very well see it cross 500ppm before I die.

This move feels radical, but I don't see how we avert catastrophe without moves that feel radical. If we keep plodding down the course we're on we'll just sleepwalk into oblivion.
Windows NT user mode code is divided into programs and subsystems.[1][2] Programs are the actual applications/utilities/etc you run. Subsystems are OS components executing in user mode, generally composed of DLLs and server EXEs which expose LPC services (a little bit like Unix daemons).

There are two types of subsystems – environment subsystems (which provide APIs to programs) and integral subsystems which provide services to the environment subsystems. Integral subsystems include the security subsystem (lsass.exe). (Sources are a bit unclear about whether there is one "integral subsystem" composed of multiple parts, or multiple integral subsystems – e.g. are lsass.exe and smss.exe separate integral subsystems, or two subsystems of the integral subsystem???)

There are three environment subsystems in Windows NT – Win32, POSIX and OS/2, although the latter two have been discontinued in newer versions. The design was always open to adding more (e.g. maybe an OpenVMS subsystem) but that never happened in practice. (Win32, despite its name, doesn't just run Win32, it also runs Win16 and DOS; also, in practice the POSIX and OS/2 subsystems were dependent on the Win32 subsystem and borrowed functionality from it, despite in theory being independent of it. csrss.exe, despite having "subsystem" in its name, is not a separate subsystem, but rather the primary LPC server for the Win32 environment subsystem.)

The term "personality" is sometimes used to describe the environment subsystems, but it is not the term the Windows NT developers used. The term "personality" actually comes from Mach. The idea with Mach was that existing operating systems could be ported to run on top of the Mach microkernel through layers called "personalities" which would map the existing OS API to the underlying Mach API. The original CMU Mach team built such a layer for BSD Unix – the BSD personality – and it actually survives in XNU (macOS/iOS/etc), but they never implemented any other personalities. However, IBM's abortive Workplace OS project actually did implement an OS/2 personality for Mach, which could run alongside an AIX personality, so they actually got closer to delivering on CMU's original vision (albeit the whole project was cancelled before being fully released.) Possibly, NT's environment subsystem idea took some influence from the Mach personality concept; plus, outside observers quickly noticed the similarity between NT environment subsystems and Mach personalities, and started using the term "personality" for the former; but it has never been the officially preferred terminology for Windows.

I've never heard anyone call WSL1 an "environment subsystem". Its method of implementation is very different from the classic NT environment subsystems. You might call WSL1 or WSL2 "personalities", but as I said that's never been official Windows terminology.

Would be interesting to see California continue over-playing their hand and eventually swing back to being a Red state.

California seems to have the curse of having enough going for it climate / business-wise that an incompetent and over-controlling government is tolerated by the population.
Looks like this was recently re-written for RISC-V. Maybe it should be called Rv6 now.
One problem with hydrogen is storing, it is rather lightweight, even when compressed to be liquid, which is good, but it is hard to contain in a steel tank. Source:

Few materials are suitable for tanks as hydrogen being a small molecule tends to diffuse through many liner materials and hydrogen embrittlement causes weakening in some types of metal containers

Depending on your level or paranoia I wouldn't touch those only in a separate computer. I don't think a VM is sufficient, there have been reports about malware that can break out of a sandboxed environment.
Amazon is up 60% TYD and is the second largest company in the world. It would be more surprising if someone didn't own AMZN.
While not EHRs, I have experience working in the EMR field, and it absolutely was a race to the bottom, vendors undercutting each other, and physicians being surprised that the cheapest vendor or product they went with turned out to be total trash.
Too little too late. How can a vehicle be "zero emission" anyway, unless the entire production and supply chain is also zero emission.
Or do columns like a newspaper, but it's unusual on the web.
Ok, so I was under the impression that if you are say, a telephone network, that people can't sue you for stuff people do during phone calls, under the premise that the phone company doesn't moderate phone calls; and my understanding of the "bargain struck" is then that online web forums felt that centralized moderation was absolutely critical to spam prevention and search/discovery services (I disagree on the practicalities here, but will admit that with 90s era tech and under the premise of the specific model of website this seems reasonable to have believed and legislate for), and so wanted the ability to "have their cake and eat it too": to be able to decide almost on a whim to take down content--and thereby to have people active to looking at content to decide what to take down--but not to be responsible for those editorial decisions, as they wanted to do their supposedly-required moderation tasks with limited staff and "after the fact": and so, if they "decide" (quite likely by negligence) to leave something up that they should not have published, Section 230 grants them immunity with some provisions. It doesn't seem like a truly end-to-end encrypted service--such as iMessage or iCloud Keychain (but absolutely not iCloud Backup, which has a key escrow backdoor: it should be end-to-end encrypted, but explicitly isn't) needs this immunity, right?
This is an interesting area of research but I'm skeptical of any world first claims. I remember a camera going to a visual area implant like... 15 years ago? And the guy got something like a hundred pixels. Not super practical but he could see things crossing his field of vision, locate certain shapes reliably etc. For a blind person that can be life changing for sure but it was a short term thing and a prototype.

Love seeing new research in this space but the science is nowhere near ready. Neuralink type stuff and other bleeding edge tech gets us like 5% of the to making this kind of thing practical for everyday life. By all means make it rain on researchers doing this stuff but don't expect miracles. The human vision system is incredible and we barely know how it works let alone how to imitate its functions. Fund basic research!!

The penalty should be much higher and I hope more people learn about this since it’s clear that large banks and central banks are one large symbiotic organism that manipulated and controls the price of precious metals to make sure fiat money continues to be worth something. It is the heart of everything that is wrong with the USA and it is the reason capitalism does not actually exist within our society.
Do you remember roughly at which point you left the game?

SOMA feels very by the numbers horror-survival at first (think: Bioshock, System Shock, etc), but this begins to unravel after a while. The first few situations seem standard, you think you have the plot figured out, and there is one escape-from-the-monster situation which is infuriatingly difficult.

However, I'd say if you give it a chance you'll discover it's not really in the survival horror genre -- some people play it with monsters disabled! -- and is in fact an exploration of consciousness and the sense of the "self". And quite interesting, too. There are some pretty poignant moments I wouldn't expect from a videogame.

I know every game likes to say this about itself. I, for example, found the plot twist and self-proclaimed "deep" plot points about Bioshock very unimpressive. But SOMA feels closer to something like A Mind Forever Voyaging in my opinion...

The problem is even more complex. For most people it is just the app right now. But what people do not realize is, that the devices networked in the car itself are trusting each other by some means of certificates. These certificates needs to be renewed regualry. If there servers are becoming unavailable for a longer time while the certificates expire, the connected device will not trust each other and will refuse to work.
The headline was not intended to be merely attention-grabbing.

It was trying to illustrate that although leaks are a fractal phenomenon, you can make significant progress by starting at the top few. For more on this, see the abstract of the Nature paper at:

https://www.nature.com/articles/s41586-019-1720-3

You'll notice the abstract focuses on what we'd call the "80/20" nature of the problem.

Going all the way to risk (of warming?) would enlarge the scope of the investigation a lot. I think I've seen talks by Riley Duren, the PI, where he gives some percentage breakdowns of the form: "CH4 is x% of GHG potential over the next Y years and in our study region, z% of CH4 came from these sources."
> it seems like I still won't be happy with it — judging by the wikis where the update is active, it's still too wide

I'm not sure what they looked like before, but I also visited a few of the localized wikis and ended up getting a horizontal scrollbar. I know that the theme on English Wikipedia is very old and not exactly responsive, but this is not something that happens there; I get no horizontal scrollbar. Everything is sized to fit within my window, except on certain articles containing wide tables or (unfortunately) multi-column reference sections, and even then, it's limited to those elements, which overflow, and the main article contents end up sized correctly. So I have to think that whatever changes they're introducing might actually be causing new problems...
This phases out car sales, not the cars. Lifecycle is 15 years, so we're looking at 2050.

For context, EVs are a few percent of sales in California, and almost zero for trucks.
So what you're doing is using anecdotal data to draw conclusions.

Your experience sounds awesome! But to think that, because you did 'Thing A', means 'Thing B' doesn't exist is odd to me.

Overt class signaling from today, at my job:

Conversation between co-workers regarding weekend plans. Co-worker A is going to her weekend house. Co-worker B is going on a float trip on her pontoon boat. I am helping my grandpa re-do his front porch steps, because he can't afford to have a contractor build a ramp for his wheelchair.

Insert blank stare from co-workers A and B here.

It's not as if someone is saying, "What car do you drive, is it worth $55,000?" Instead, they question as to why you drive a 10 year old Kia instead of trading it in, YEARS ago for a new car. They then make you the butt of any jokes about being a cheapskate or penny pincher, when in fact, that's all you can afford because you're supporting an extended family still living in poverty.

It's not as if someone is judging you based on your clothes, by explicitly saying things like, "why don't you wear a tuxedo" or whatever. But it may be that you are passed over for promotions, because you can't afford the clothes to fit in at the golf club (let alone the fees for the membership), so you don't get to rub elbows with executives. That's if you even understand that's a thing.
The desire to see consistent behavior as incompetence is a shield. Firefox was intentionally destroyed, and gets all of its revenue from the company who replaced it.

It's like Nokia all over again; the plurality of people who are watching this failure predict every step of it, but are denigrated as antisocial, selfish, mentally-ill trolls. As they leave, the ones who remain are attacked more, because now they're outnumbered in every conversation. Then the company fails.

Of course, in this case firefox will never disappear, but stumble along like a zombie, forever, because google needs it for antitrust purposes. Mozilla will do anything but work on its browser, at high salaries, rife with self-dealing and cush jobs handed out to the most connected, while claiming the languishing firefox as its emotional core and charitable mission. The work done on firefox will consist of tests for things that chrome is thinking of doing, or the non-disableable incorporation of acquired companies or partners into its functionality.

There's no system for calling them out on this other than just calling them out on this. They don't have any duty to us.

Firefox Focus also wipes itself frequently, which means that you can't be tracked across sites as easily. I look forward to updating to iOS 14 so I can set FFF as my default browser.

My typical workflow is: (1) search for something in FFF, (2) if it's something I want to stay alive so I can read later, I share it to FF, (3) if it's something that I need to be logged in for, I share it to Safari, where I'm logged into various sites.

It is annoying that I have to manually open FFF each time, instead of being able to use Siri to trigger a search or the systemwide search. Hopefully both of these search options will use my default browser in iOS 14.
Using Wikipedias language switcher to translate things seems to be quite common here, so I thought I'd share how I moved the languages up on top, so I don't have to scroll down on smaller screens or when zoomed in.

In `<firefox-profile>/chrome/userContent.css` I wrote the following:

@-moz-document domain(wikipedia.org) {
#mw-panel {
display: flex;
flex-direction: column;
}
#mw-panel nav {
order: 9;
}
#mw-panel nav#p-logo {
order: 1;
}
#mw-panel nav#p-lang {
order: 2;
}
}

This is only for Firefox, but imho that is the… least bad browser anyways ;)
Operating systems are basically a commodity. Browsers? Doubly so. I don't care who's in charge of Mozilla - if your "product" is your browser, you better hope your "customers" feel charitable. "If everyone donated $2.99.." and etc.

Maybe you just can't run a successful business in the browser space in 2020. It was already plenty difficult in the mid-90's, wasn't it?
1. Please note that ‘obligation’ is not the only standard at play. Companies exist in a social and economic context. (I have previous comments on this topic that can be easily found.)

2. The ‘if you want a company to be run differently, start your own’ argument is tiresome and weak. There are (and should be) many mechanisms to influence corporate behavior.

3. Even the pre-Trump Republican Party has long taken flack from libertarians who essentially argue that one core principle should guide their political philosophy.

3B. Personally, I have not found a strong philosophical grounding to claim that political philosophies should be reducible to one core thought from which everything neatly derives. (That would be nice, wouldn’t it?) In my experience, figuring out public policy decisions is fundamentally more complex than that due to the interplay of conflicting values and moralities.
> It's approachable, and doesn't fall into the interpretation biases of the reporter.

I agree with this, but don't forget that interpretation biases will still come into play as the law is enforced — the biases of police, lawyers and judges. So it still makes sense to read others' interpretations of what this might mean in practice.
But the energy density per mass is still better than Li-ion batteries.
> Game designers/programmers need to follow the same formula.

Thats basically impossible though. Because, at some point, programmers from other industries, will just enter the market.

What, are you going to try and unionize the entire tech industry? Because I'm not going to go along with that (I will defect, every step of the way, if people try to push me into that arrangement).

And if you don't unionize all of tech, then programmers from outside the industry will be able to compete for those jobs.
