The problem is that hydrogen is a submarine; most of the people advertising it at the moment come from the natural gas industry, and they want to sell H2 from natural gas as a "stopgap" and hope that nobody asks where the CO2 goes in practice. You could make it from electrolysis, but unless you check all the time, that's not where it actually comes from.
I'm not sure they are a Java company, they are more Python, PHP, Golang, and Node. At least Java is not described in their job offers, which are usually a very nice way to know about the company stacks by the way.

head in hands

For what it's worth, my bosses all the way up to CEO of a 50k person company were all pretty pleased with the working practices I used (medieval things like strace(1), perf(1) and sort(1)) to save thousands of servers' worth of CPU. I'm not advocating for editing code live over SSH but there are still plenty of legitimate reasons to SSH into a server and use UNIX tools.

Since you're clearly trolling I'll leave it here.
Again, your personal anecdote is not important, because it's not representative of the normal story in the US. Your story is exceptional.

The number of people who 'don't go to college and end up in in highly paid tech jobs' in the US is very, very small.

I wish Rust used prefix &[]i32 for a slice, and [5][2]i32 for a 5x2 array. Instead it uses &[i32] for a slice, and [[i32; 2]; 5] for a 5x2 array. Reading types backwards is alive and well.

> Hydrogen should have around 50% round trip efficiency from electricity back to electricity and it can (partially?) reuse existing infrastructure for natural gas.

It can't though, not without significant studies and possibly rebuilding them entirely: the temperatures and / or pressures involved are different orders of magnitude, and nat gas does not embrittle.

Industries have started trying to blend hydrogen and natural gas to transport the hydrogen, and even that's turning out to be rather risky[0] unless the line was designed specifically with that use in mind.

A PWR relies on natural circulation to maintain core cooling in a blackout. Reactor Coolant Pumps aren't even considered required emergency equipment and are not connected to emergency power supplies. In 25 years of commercial nuclear operations experience I've never heard of an NRC delivered emergency diesel generator. I would like to see the helicopter big enough to lift the typical EDG. I have no experience other than basic knowledge of a BWR.

> I reported the death rate. It didn't increase dramatically yet; only from 12 per day to 30 per day

The death rate per day is not what is typically meant by the "death rate", and it suffers from the issue I described: it will absolutely go up as long as cases go up, but that isn't an indication of severity. The "death rate" in the context of epidemiology means the number of deaths per case, not per day. This is what differentiates extremely serious diseases, like ebola, which are rare, but have a death rate of around 50%, vs the flu, which is common but has a death rate of less than 1%. So yes, daily deaths are increasing in South Africa, but the number of cases in South Africa is skyrocketing as well, so it doesn't really tell us much.

Apple's PE ratio is half of Netflix and Amazon's, despite them being in a clearly dominant position. I think tech is probably overvalued, but if the market's right about tech (and in the end that market is usually right), the only reason Apple isn't a $6T company is because investors simply don't have enough money to throw into them.

By dominant position I mean Walmart.com is 90% of what Amazon is, HBO Max is imho better than Netflix, Bing/DDG is as good as Google for most searches, etc etc. No company is within 1% of replacing Apple.

https://www.philscomputerlab.com/windows-98-dma-mode.html

I wrote about this in PC Pro in about 1995-1996. Because it had a true pre-emptive kernel, it could do other stuff while waiting for disk I/O, and on NT, enabling DMA made a big difference. As I recall, on 98, it just made disk access a bit quicker, that was all.
Wind and Solar production are literally free though. So why do you care about efficiency?

In practice, the price of electricity swings roughly 300% during a given day in California. At 12pm, there's so much solar power that most people's panels are turning off and electricity is damn near free.

At 7pm, there's so little energy on the grids (and the Peaker plants are having such a hard time keeping up with the "duck curve"), that the price of electricity skyrockets.

---------

Unless you plan to have your electric car charge at exactly 12pm every single day to take advantage of that excess solar energy (while also negotiating to participate in the raw electric energy market), all of that free solar energy is basically worthless to you.

In contrast, something like Hydrogen storage can "store" electricity by just creating more hydrogen.

-----

Perhaps you think that void can be filled by Li-ion batteries. But that comes down to a Li-ion vs Electrolysis question, and its almost undeniable that concrete-and-steel for storage is cheaper to build out than buying Lithium-ion / Cobalt / SiC MOSFETs / etc. etc.

What we want are machines that can suddenly grab all the free electricity off the grids at 12pm, and then they turn off by 7pm (for the duck curve), and then maybe turn on again at night (depending on the price of electricity). A "reverse peaker plant" if you will, that only uses electricity when the prices of electricity are cheap.

Hydrogen works for that. Li-ion is too expensive for this still.
I am not arguing against his thesis. The presentation and tone just puts me off.

And even if he is correct, that doesn't give one the moral authority to look down your nose at the opposing camp. Its difficult to say that someone else swallowed the Kool-aid when you sound like you drank some of your own.
If you're at a building site in the middle of nowhere and need 100kW of power for a few months, you can't be shipping massive batteries or flywheels there, bringing in a few compressed hydrogen cylinders each week isn't a problem though.
Maybe some reliance on authority is a good thing?

Because the answer crytpocurrency provides to "how much are you willing to pay to never have to trust anyone" is "one hell of a lot" via work-factor.

A fundamental characteristic of all exchange systems is trust. That may not be institutional trust, but there is trust in something: mineral scarcity and assayability, counterparty, commodity-currency acceptability by others, pricing and exchange systems, recourse options, etc.

In economics, there's a long observation that high-trust markets and the societies in which they exist perform vastly better than low-trust ones. And interestingly, cryptocurrency fairly neatly segregates markets into those who do have fundamental trust in institutions and practices, and those who do not.

I echo your sentiment that this is a less evolved form of government. The next steps will be to reduce the violence, segment the criminality to the youth, and the former leaders of the movement will move to government and business ventures. There is not going to be public organization against these groups. They’ll clean up their image as they secure stability.

This evolution is also the plot of The Wire.
> RSS was first released/specified in 1999, so to say that the idea was to escape platforms like twitter is rewriting history

But they said "proprietary platforms like Twitter", not Twitter, so they would not be wrong in making that statement. Except, in an unexpected twist, RSS was actually initially developed to be used on Netscape's proprietary portal. It was not until a bit later that the open standards, anti-monopoly group won out.
Yes. Browsers really should maintain HTTP support. There’s no reason to require every static site in the world to be encrypted in transit. And in particular, there’s no reason to block off all the actual good websites that are old static sites still serving their purpose.

You haven't addressed internal motivation or external drag in your model. There's always an answer to the "why don't they just.." kind of questions, and if your model doesn't encompass those it won't be useful.

Of course, even collateralized loans to buy real estate are not, despite what you said earlier, risk-free--see 2008 (and google the term "CDO", in case you've never heard of it) for a rather dramatic example of this.

More to the earlier point, though, this is really not how most lending works, so the idea that this somehow means that "absent central bankers, we'd all make 2% APY risk-free on bank deposits" is just silly. The global equity market is $50T, the global corporate bond market something like $100T. Total cash-equivalents (M2) in the US is $21T.

Even if "pledging shitcoins as collateral for speculating on coinbase" were zero-risk--which of course it isn't--the market for such loans is, unfortunately, too small for all of us to retire risk-free.

I thought of Idiocracy as well today, for another reason. I saw on instagram a video of a groom holding a bride in his arms over a mud puddle for a photoshoot. At some point the groom tripped and dropped the bride in the mud: she started screaming and crying. The video was clearly staged. It made me thing of "Ow! My balls". Somehow, ragebait is even worse than sophomoric humour.

> As TypeScript is a core part of the Deno ecosystem, we are also very interested in pushing for even closer alignment of TypeScript and JavaScript in the future.

I've wondered why the frontend community hasn't gotten together and said, "The next version of JavaScript - is TypeScript!" I've been using TypeScript for five years professionally now and cannot understate how much easier it has made large frontend (not just Web, but mobile and desktop) projects. Surely enough thought and work has been put into TypeScript to make it the next standard.
That is why I dug into the article a bit further. Editorial teams in sites are notorious for taking the author's suggested title and replacing it with clickbait BS.

Most local government websites are maintained by a handful of compliance specialists that provide hosted solutions; if your government even has an IT department (as a nearby city to me does) it is probably more a cause for concern than anything else (they seriously assign unchangeable passwords to people that follow a pattern based on your name so you can guess anyone else's password... it is crazy).

https://carcd.org/wp-content/uploads/2018/10/Sloane-DellOrto...

But so like, if you want to lobby a local government to add some feature to their website, they aren't even effectively going to be able to do it; but if you can convince a company like Streamline to add it to their offering, then you'd suddenly experience like half the local governments in California all getting that feature at once.
I have to wonder: how much of a factor is social pressure in this setting? Any hypothesis geared around IQ being anything other than something that is malleable with education seems to be "too dangerous to handle" for any serious scientist.

I am not a social scientist, but based on my experiences seeing people attempt to learn programming, it seems like certain types of thinking patterns cannot easily be learned by everybody.
> you do know that even before modules you had to explicitly setAccessible if you wanted to break through access control

Yes, I do know that, and I'm fine with it. If it still worked then I wouldn't mind modules. My complaint in particular is that a command line whitelist is needed for setAccessible to work anymore.
Oh yes, I see, that's true. Thanks for the explanation.
> We found that skin cells possess a receptor called OR2AT4 that responds to the scent of sandalwood, frequently used in incense sticks and perfumes. And we were able to activate this receptor using Sandalore, a synthetic sandalwood scent.

> Using samples that included cultured keratinocyte cells and human skin, we discovered that activating OR2AT4 triggered a signal pathway that led to a higher concentration of calcium in the cells. This in turn led to an increase in the proliferation and a quicker migration of keratinocytes – processes which typically facilitate wound healing. Scratching experiments on isolated human skin tissue confirmed this wound healing effect.
British culture is very much not homogeneous in this regard. The use of words like lovely probably tells a British speaker more about the geographical origin of the speaker than their sex.

True. Irish in its heyday had four rather different dialects, but today only the artificial compromise "fifth province" amalgam is taught in schools.

Same with Japanese. There are some proudly, stubbornly distinct phrases in Kansai-ben and other regions, but the choice of the Meiji-era government to only teach Standard Tokyo Japanese in schools has had the desired homogenising effect.

Even as recently as the 1940s, there are well-documented cases of teens from the south of England, sent to the north of England, to work in mines for the war effort, who simply could not understand the variety of English being spoken around them. Radio and TV smoothed out all those differences.
This hurts.

RSS is the only way I know, without having to scrap things by hand, to get an aggregate of "news/articles" from the sites and blogs I follow, and I consider to be of good quality.

I prefer to filter my information like this, instead of having to rely on some algorithm, or endlessly scrolling in a "social medial wall" full or clickbait articles, immortal/vintage memes or exuberant rants.

If RSS dies, what is the alternative then? I understand that technically speaking it's not a good solution, but let's have something else before killing this.

PS: I've clicked on this link from a RSS reader (just a simple browser extension... that keeps me posted every morning).

Unfortunately the negative effect for my end remains. Sometimes there is no ideal solution for everyone, I guess.

The vast majority of the increases in education spending over the last decades have ended up expanding the state-level bureaucracies rather than making it to teachers and classrooms. Until we make some kind of change to the systems that ensured that outcome, we can expect the same to happen in the future.

The amount of spending isn't the problem -- we've consistently increased spending. But that increased spending doesn't increase classroom budgets or teacher salaries significantly.
Don't constexpr All The Things [pdf]
Ask HN: Which employers in Germany would be interested in my skills?
I am graduating next year with a Masters in Mathematics, in Germany. I also hold a Bachelors in Mathematics and a Bachelors in Physics. In my Masters I focused on numerics, numerical methods, finite element method, simulations (molecular dynamics and sph), machine learning and data science. I have programmed many things in many languages and am pretty confident I can pickup any required technical skillset easily. I am currently also employed as a research assistant applying Graph Neural Networks to engineering applications.

I would say my three biggest skills are:
1. mathematical maturity, being able to make sense of any given piece of mathematical literature (with some patience and time of course)
2. analytical and methodological mindset, in simple words, am good at problem solving
3. extensive experience in software development across many domains from web dev to running simulations on HPCs.

My areas of interest are mostly numerical simulations and deep learning. I don't like data science that much.

Now, the question is, which employers (preferable in Germany) would be interested in my skillset? I am at a loss where I should be applying for jobs. I have a pretty safe career trajectory in academia if I want to go that route, but I am also exploring alternatives in industry or maybe in some research institute other than my current institution.
> But if you're a fleet operator (ex: Delivery trucks or Semi-trucks), suddenly you care more about the cost of refuelling stations.

The concrete and steel station of hydrogen refuelling is quite a few steps (miles) beyond petrol though, and the danger (and thus the additional security risks) are in an entirely different realm as well.

> So I dunno, lets have the methodologies compete and may the best tech win?

The problem is... compete how? Because currently electricity has already won (if we ignore the elephant of fossil fuels in the room).
That's memetic selection, right? Like, the assimilation is going one way.
