It's not a cult. But as alluded to in the article it's an attempt by a dying business model to amortize some of their investments. A move to BEVs breaks lots of business models.

For example when people stop refueling: Gas station shops lose customers, fuel transportation companies lose contracts, technicians maintaining the pump systems lose jobs, etc.

Lower maintenance BEVs also mean: Less work for car mechanics, lower sale of ICE maintenance products, like lubricants, less parts in a BEV also means less work for lots of automotive suppliers, etc.

Using hydrogen instead of batteries could save or at least extend the lifetime of a lot of these business models. That's why these companies try to push hydrogen so hard.
Look, I am a builder at heart, too. I love writing software for all sorts of reasons.

When I am working for someone who is paying me, though, I am only building for one reason; to deliver value to my employer. That is the entire reason I am being paid. I build for other reasons at other times.

I really hate working with other developers who think like you do. It is so hard to work with people who care more about the code itself than what it is for. We aren’t working for the same goal, and sometimes the beautiful code actually makes it harder to accomplish our actual goal.

One (of the many) problems with predicting a societal collapse is the word itself, "collapse", being incredibly vague. What would define a collapse? For most it seems to conjure up visions of apocalyptic disasters. But it could potentially be a long, drawn out change to the trajectories of many metrics surrounding human population and economic activity. Who knows? I doubt we will even be able to define what a "collapse" is, let alone predict when that collapse might occur using modeling techniques.
This is by far the dumbest take I've ever seen on the matter. No, people aren't obsessed with hydrogen because they can fill up in 5 minutes, because for the vast majority of car buyers, charging at home is an even better idea. Hydrogen cars are unlikely to ever take hold outside of maybe the taxi market, which is why so few automakers are investing in them. But there is a massively promising market for hydrogen trucks and other long haul transport. There is a reason why the company that actually released the first electric truck has invested billions more in hydrogen research.

It's all about the energy density.

>Why would psychologists believe something so clearly wrong?

I would imagine from their research? Why are you so self-assured that you are right?

Often the issue with 'IQ' tests is that the way they are written introduces biases. Any definition of intelligence is at some level socially constructed, which brings social biases into play. Designing accurate, fair, and reliable tests of any educational measure is difficult. Doing a generalized one is even more so.

really obvious example: I write a question that references a baseball game, some people have the tacit knowledge that there are nine fielders and one batter...some don't. Am I measuring education? information gained? 'intelligence'? Is someone from India who makes an analogy to cricket more intelligent than someone who doesn't? IQ tests have generally been shown to mostly be predictive of...scores on IQ tests.

Fundamentally, when dealing with people you are dealing with latent constructs. They, by definition, cannot be measured directly and we presume they cannot be measured exactly. The issue in this paper is they aren't even really defined - they measured cognition not 'intelligence'.
Too loud for an office. Which is a shame because in these pandemic times, I repurposed the shed at the bottom of the garden as an office (insulated, add power and a/c) and I wanted it there.

It's not noisy when writing to tape, but the mechanism is noisy when a tape is being loaded, the magazine is being shuffled to get the right tape, etc. It's the mechanical parts rather than the tape drive itself that's too loud, especially with Webex conferencing being a part of the day now.

So I have it set up in the garage, in the server-rack. I was worried about temperatures in the Summer, so I bought a 100W solar panel, an attic fan, and linked them up, positioning the fan above the rack. That fan shifts so much air that the in-rack fans (with temperature monitoring) didn't get above 85 all summer, which is pretty amazing for the Bay Area. The tape deck seems to be fine in that sort of temperature, and yes I do do the occasional 'tar tvf' to check the data is readable :)

That's it, we work in a pretty privileged market where we can more easily vote with our feet, generally speaking.

Of course, we also work in one where wages can end up being pretty exorbitant, and where there's plenty of people who are morally flexible depending on their own conscience, compensation, or whether the ad tech is wrapped in hype-driven development.
I enjoyed that. By the way, the expression is "couldn't care less". If a robot could care less about a celebrity, then there would be some value in them as it would be possible for the robot not to care as much.
IQ scores tend to correlate with IQ scores...whether you think they are representative of a holistic intelligence is somewhat up to you.

These researchers looked at studies of cognition specifically, and did very little to control for the variety of measures of cognition that are out there or their disciplinary or general context from what I can tell.
I'm so confused about where education and student abuse and large donations entered this conversation...
You've got data on how many southern-border-crossing immigrants make it into the US middle class? I couldn't find any.

Most immigrants in the US do not "stream over the border", more are arriving from Asian countries than Latin American countries. Those that arrive by air from another country typically have more than "nothing" on arrival.
IIRC, there were companies running pure CGI simulators in the 70's, so that could be the out of the window imagery for the astronauts. I'd love to know more about the software (and, mostly, what appeared on the three MFDs of the original shuttles, as well as detailed images of the glass-cockpit MFDs that are on this simulator.

IIRC, the original ones were not raster displays, but long-persistence X-Y displays.
> Wind and solar have phases of overproduction and hydrogen generation seems sensible here

Is it though? The round-trip efficiency of batteries is 70-95%, for flywheels it's 90%, for hydrogen it's under 50, and all the usual problems of hydrogen (danger, absolute pain in the ass to store, embrittlement) remain.
That's really beautiful, awesome work and explanation of how it was done!
In the UK, there is no chance they'd just have guard dogs roaming around without a handler. It is illegal, and even if it wasn't the liability would be insane.
In any case a security dog has to be trained not to inflict any serious injury.

If someone called the police, that would have been a good thing as they'd have let me out. Trespass on non-residential land here is usually not a crime provided you don't do any damage.

Besides, I was in my mid 20s so such risk taking behaviour was par for the course. I was much more worried about getting a fine for a late return. Even now I still do a little bit of urbex from time to time.
All I can think about while reading your comment is "I'm a people person, dammit!" from Office Space. It was not a playbook on how to run an actual software company.

All employee incentives should be aligned around selling more product and lowering cost of delivering said product. The closer that marketing and software work together the more they can empathize with each groups challenges.

Using your example, what makes a product feature essential if it does not in fact sell?
5 years seems like far too small of a window to accurately assess this. Was life better in 2010 than 2005? How about 1977 vs 1972? Or 1803 and 1798?

A much longer time frame will be required to determine if life is improving over time for people or not. Possibly on the scale of generations.
One of my weirdest fixes was removing a duplicate database request on an admin page that was taking 30 seconds to load. But instead of dropping to 15 seconds, the response time dropped to 3 seconds.

I've also removed a lot of 10% calls that improved performance by 20%. Profilers don't show the cost of your code to the CPU and Virtual Memory caches. And there are new or malloc calls whose full cost is paid by another thread due to the tempo of the allocations.

As you say, looking at the count column is a huge thing. But the biggest failure I've seen is one of imagination. So many people give up when the last tall tent pole has been addressed. Even if we've only hit a 3rd of our performance goal, they believe they've tried everything and we should move on. Nobody knows how to do perf analysis with a budget. For instance, the 'current users' count should not be entitled to 10% of the page load time.

> any service provider needs to have some discretion on these things

Of course, but that's not the issue under discussion.

The issue under discussion is the combination between (a) how vague these things are (b) the extremely wide range of badness (don't tell me that "self-promotion" falls into the same category as "spam/scams") and (c) the fact that your email account can be locked if you violate these rules on the forum.

It's one thing to claim that you're closing someone's forum account because they were harassing someone on it, and another to close their email account. That's not protecting your forum, that's trying to give yourself the ability to legally retaliate against someone for anything that they did that you don't like.
Vintage Mobile Phones (subreddit)
I went to the local store to buy 4MB (4x1) for a computer I was building but they accidentally gave me 16MB (4x4) for the same price. Then they went out of business, turns out it was a money laundering scam; guess they didn't know or care exactly what items went out the door.
But I would just say the same thing. The differences in income inequality are going to completely swamp any such effect from differences in spending.

Maybe paying for college is an exception to the rule -- only because of all the grants, scholarships, loans, and income-based tuition.
Although it’s qualified later in the article, this headline is pretty wrong. There are definitely use cases for hydrogen…. It’s just not cars or utilities.

I used to find most stocks including Apple to be overvalued a long long time ago. Even when Apple was worth 500 billion. Thank god I never shorted a stock in my life. Would have probably lost my shirt especially with Tesla. This is despite the fact that I knew that the Fed printing money would lead to an asset price inflation.

Would you still increase the price if the main competitor with the biggest market share is already cheaper (one-time payment of $5)?
I think it is both.

It's not as elegant but you'd only ever use Html.Lazy for performance, so this trade-off seems to make perfect sense.

RSS takes less bandwidth than doing the same operation through direct visit. And of course, one is not supposed to do it that frequently; though again, some browsing agents may load pages more frequently than every minute.

It doesn't really work like that - you can produce and share exceptional resources, but that's not a substitute for a good teacher in the room.

Education definitely can scale, but good education scales much less well than slick-but-ineffective education.
There is a bit of word drift too.
Hydrogen makes more sense when you consider that fillup stations are built with concrete and steel... while electric is full of SiC MOSFETs, expensive electronics, and a ton of copper to pass through 2MW of electricity.

There's a tradeoff of course. What's easier for refueling stations is less convenient for the consumer. But if you're a fleet operator (ex: Delivery trucks or Semi-trucks), suddenly you care more about the cost of refueling stations.

So I dunno, lets have the methodologies compete and may the best tech win? I'm mostly just happy that a variety of alternative fuels are competing now.
If you are solo, any time you spend doing anything else than coding and improving product is a complete waste of time. A well done product will raise interest in a given market or segment.

I really wish people would mostly stop doing this type of utterly and completely necessary "correction." It really misses the point, and exemplifies nearly the exact opposite of the point and value the original article is expressing.

Teachers salaries are mostly about right, and the 'problem' in America is generally not the education system to which most people who achieve to any degree have access ... it's social conditions.

This thing about 'amazing teachers vs. terrible teachers' is a really, really bad mythology.

Most teachers are decent and as long as they are paid reasonably well, the quality will not rise, they are not motivated by income. The very notion implies a lack of understanding of communitarian values.

In the worse neighbourhoods, kids don't show up, they are years behind, their kids are making money in gangs, they face violence and threats, they have no peers into academic stuff, they have no role models, they have no money, they see no reason to finish.

But the same school and teachers magically transplanted into an upper middle class neighbourhood will flourish.

America invests more as a % of GDP in education than most nations, even raw $ per student [1]

The other thing that nobody wants to contend with, is that America has a giant community of migrants, often undocumented, from very poor countries with a different culture that live in more segregated isolated communities, and form a kind of 'working class backbone', but which makes it harder for their kids to break into the middle class. The surpluses from this labour are immesurable.

California and Texas are rich at least in part because they have millions of people willing to work very cheaply in addition to millions who will work 'off the books' even more cheaply - and who do the work well because they are 'happy to be living the dream'.

PISA (OECD) standardized testing (see: 2018 and historical) shows this stark difference: Asian and White kids have done consistently well for decades. Black and Latino kids are consistently 'doing a bit better' (i.e. closing the gap), but the increase in their population offsets the net improvement and drags the average down.

The 'education' issue in the US is a giant canard. If you can get kids into good families, with good parents, stable jobs, no violence i.e. 'what you and I would normally expect in life' - those kids will do just fine in the current system as it is.

OK, yes, that's entirely fair, although I have to say that in 1998, 1024×768 was quite big and asking for it in true colour as well would be… optimistic.

I think it got swapped out as soon as it could be, though. I remember moving windows aside on low-end machines and hearing the hard disk chug as it loaded the previously-obscured bits of the desktop image back in, scaled them and redrew them.

(I don't remember when Windows gained the ability to scale the wallpaper. IIRC, it was in the Windows 95 PowerToys – the base OS couldn't do it. I think it also only understood `.BMP` files originally. JPG and other compressed formats only came later – probably in 98, come to think.

I had a few such machines that could do 1024×768×24, but they were pro-grade kit, and as such, I ran NT 4 on them, not GameOS®™.

About 1997 or so I was rather proud of my Pentium II 450 MHz in a Baby-AT case (not ATX) which had 2 Matrox cards, allowing me to run a dual-head desktop at 2048×768. I think I then went from 2×14" screens to 2×15" which allowed me to run twice 1152×864: 2304×864. So… much… desktop!

Your guess seems better than mine. I was thinking they wrote the code wrong and somehow attached itself to the message pump in the processing path. Hmm, that could still be it and they were using a timer to tickle it here and there. But that is all speculation. But waving the mouse around to make run faster really sounds like a message pump issue. Or maybe they used getmessage instead of peekmessage?
It feels like the main two factors for EVs in play here are efficency and charge rate. Greater efficency the more green, while faster charge rate the more like what we're used to, therefor adoption. Not to mention longevity, which is already degrading across the board.

This is cool but if we're not bound to static paper maps isn't the ultimate adaptive projection an interactive 3D perspective rendering of the globe? I suppose the downside is that you can't see both hemispheres at the same time.
