> The scientists said gray, black, and brown hydrogen release 9 to 12 tons of carbon dioxide for each ton of hydrogen produced. Yet, they correspond to 95% of all hydrogen currently produced worldwide for agricultural and industrial needs. Even if this green hydrogen does not help move a vehicle, it is a welcome way to curb the production of the gray and black kinds.

It will only do that if countries put laws in place to require green hydrogen. green hydrogen is not just expensive because it is new, but theoretically expensive because there are currently two routes to turn natural gas into hydrogen:

gas -> combined cycle gas turbine (40% loss) -> generator -> electricity

electricity -> electrolysis (10-50% loss) -> hydrogen

gas -> steam reforming (25% loss) -> hydrogen.

From this, you can make equations bounding the prices of gas, electricity, and hydrogen for any process to be profitable. It turns out that for the middle process to work out economically, the first must be non-economic. ie. the price of electricity must be very low while the price of gas is very high.

With gas just flowing out of the ground in the USA, russia, saudi arabia, and others, this will never happen. In fact, in many places the price of gas is so low we just burn it off because it isn't even valuable enough to collect or transport.
This article is patronizing and tries to simplify the complexities of managing people by putting them into buckets and listing recipes.

For me, this type of view only causes more harm than good. Instead of actually sitting down with the "difficult engineer" and figuring out what is happening, managers will label them as "X" and poison their view of them moving forward. Sometimes even publicly.

Good managers know you're dealing with people and you actually get to the bottom of what is happening on each situation. As others pointed out, there may be a reason you're the "lone wolf", "procrastinator" or any other of these simplistic labels at any given moment.

But the average manager just wants labels and recipes to follow, which this type of article provides. Then when reality hits and nobody perfectly fits those buckets and the recipes don't really work as expected, all we can hope is they realize how bad of a manager they've turned into.

To any managers reading: do your actual job and remember you're dealing with real people. Don't label everyone and follow magical recipes. That's how you become a bad manager.
I worked on a piece if software that had originally been developed by a single engineer who fit that description. After struggling to understand and work effectively with the code for some time, and questioning my own abilities, I learned that much of the code had been written under the influence of LSD…and everything made so much more sense.
Neat - I signed up and played with it but why would you take access away? That makes me want to stop playing with it! Which is a bummer because I've always wanted to learn CAD and this really does seem like a much more palatable CAD product than any other I've seen. I'm only a hobbyist/probably not really in your target audience but snazzy product you've got here.
I don't know why there is any doubt about that. Maybe it's only because I am older and was DoE-adjacent in the relevant timeframe, but I distinctly recall the pitch for funding NIF was 100% pure weapons. They even wrote it down:

https://www.osti.gov/biblio/50733

"""
The National Ignition Facility (NIF) will enable us to produce energy densities (energies per particle) that overlap with the energy densities produced in nuclear weapons, yet the total energy available on NIF will be a minuscule fraction of the total energy from a weapon. This combination of low total energy with weapons-regime energy density will allow us to pursue, besides ignition experiments, many nonignition experiments. These will allow us to improve our understanding of materials and processes in extreme conditions by isolating various fundamental physics processes and phenomena for separate investigation. Such studies will include opacity to radiation, equations of state, and hydrodynamic instability. In addition to these, we will study processes in which two or more such phenomena come into play, such as in radiation transport and in ignition. Weapons physics research on NIF offers a considerable benefit to stockpile stewardship, not only in enabling us to keep abreast of issues associated with an aging stockpile, but also in offering a major resource for training the next generation of scientists who will monitor the stockpile.

This is something very Japanese, they like to patent everything to the extent I think it's something cultural. My company (Japanese owned) made us sign something on the lines that the company can patent inventions of employee without his consent.
It’s more like anti-100k debt for no apparent gain.
How in depth are the modifications?
I think I had it recommended to me here before, so I’ll do the same now. I’m reading the Commonweal series, which starts with “The March North”.

It’s a really, really hard book to get into due to the way it’s written, but its really a quite unique fantasy world populated (and historically ravaged by) wizards and sorcerers.

It also has a fire breathing sheep called Eustace.

The rest of the series basically constantly expands on the world and the lore through the interactions people have, generally with different viewpoint characters.

I’m down to the last book, and a bit sad that the trip will be over.
It's an article about how fusion is still far away.

It's technically cool, yes, but we need electricity now, and tomorrow, not next century.

I'm excited for fusion as a human accomplishment, as high tech research, maybe as a power source for future spaceships.

But I think it's likely the time may never come when it's used to generate power for the electric grid, and expecting that to come soon is just naive. We don't even have a single fusion plant that produces power yet, let alone the hundreds of them that would be needed for the tech to have a real-world impact.
Why we sleep. This book motivated me to change my sleep habits after decades of being a night owl. I’m starting to love early mornings, and I feel so much better. This was a hard change.

How to do nothing. About resisting the attention economy and reorienting one’s relationship with technology and the environment. A very thought provoking and timely read, especially while I’m on sabbatical.

Flow. Explores the psychology of optimal experience, and again has been rather applicable while I’m on sabbatical trying to recover from burnout. It explores the flow state: how people achieve it, why it’s so enjoyable, and shifting towards a mindset that seeks to find flow in everyday moments.

Learned Optimism. Explores the original research that revealed the concept of Learned Helplessness, provides tools to assess one’s own level of optimism/pessimism (this was…revealing), and makes a strong case for replacing certain pessimistic defaults through simple retraining exercises. Really helpful if you grew up in an environment that hammered pessimism into your core. Has been life changing.

One "solution" to this problem in Linux is to use something like bwrap[0] and manually redirect offending software to the desired location with the "bind" option.

You probably can't get the individual directories for different purposes (.cache/.config/.local) because offending apps are unlikely to have these concepts (otherwise they probably wouldn't be offenders to begin with...) but you can just slam everything from $HOME/.foo into e.g. $XDG_CONFIG_HOME/foo and go.

"Anne Frank Remembered: The Story of the Woman Who Helped to Hide the Frank Family" By Miep Gies.

(The Disney+ series "A Small Light" is loosely based on the events in this book.)

Miep was Otto Frank's employee, close friend of the Franks, and helped hide the family during the time that Anne wrote her diary. (She was the person finding the Frank's food.) After the Franks were arrested, Miep rescued the diary and then gave it to Otto Frank when he learned that Anne didn't survive the concentration camps.

The book gives significantly more context than Anne's diary regarding who the Franks were, and the struggles they encountered. Not only is it a vital companion to Anne Frank's diary, Miep's account of Amsterdam during WWII describes in detail what life was like under the Nazi regime. She gives a lot more of the "who, what, where, why, and how," that Anne's diary omits. (Remember, Anne was a teenager who, initially, was writing for herself and not for a global audience.)

The first section of the book describes some of Miep's background, how she met the Franks, their relationship, and the history of the Franks. The second section describes the period where she helped hide the Franks, and often gives an alternate perspective to events that Anne wrote about. The third section describes the Frank's arrest and the famine that happened in Amsterdam before the Germans surrendered.

I read the book because some events in "A Small Light" were a little difficult to believe. And, yes, the events in "A Small Light" that I didn't believe weren't part of the book.

Edit: https://www.amazon.com/Anne-Frank-Remembered-Helped-Family-e...

Edit 2: I also recently re-read Anne Frank's diary. As an adult with children, it provides a strong reminder of how teenagers' minds work. It also shows that even our heros were immature as youngsters. In Miep's afterword, she points out that she was really hurt at the way that Anne described some of the people in hiding.
> One key implementation decision was that the Z8000 would not make use of microcode. Microcode would have broken down the Z8000’s instructions into a series of simpler instructions, hidden from the outside world, which the processor would execute. Instead, all instructions would be ‘hard-wired’ into the logic of the CPU, a more challenging approach for the designer. Shima would later discuss how much more difficult the Z8000 was to create when compared to the Z80, and how it tested the limits of the tools that he had available:

“… there are so many instructions in Z8000 it is impossible to store all of test vector for debugging in the memory of test bench anymore. Also, MOS process was getting denser and denser and also the size of the defects in masks was getting smaller. That is it was not so easy to find the fully functional die.”

This seems like a remarkable engineering decision to go entirely without microcode. Are there any comparable examples post 1979?

Not grouping those advancements together -- they're wildly different. Suggestion is that the reaction by (a section of) the public to those advancements is similar, and reveals something about our collective psychology.

Slackware in my circles around '99 was always the elitist option from day one.

You were using Debian, Red Hat or SuSE? Not Slackware? Pfff... normie.

I think that consolidated it as difficult for beginners. The fact it offered very few technical advantages was the nail in the coffin.
To be honest, it already feels like a resource denial effort. Reminds me of Paul Virilio’s description of systems that deliberately inhibit human speed.
>Most batteries are around 90-95% efficient. Electrical motors are around 85-90% as well. So that isn't that bad.

I guess you'd also have take into account loss during transmission (which seesm to vary wildly between 2-10% depending on location) and charger efficiency. IIRC if we add it all up it's about 70%.
It's not enough to be a novel approach. It also has to be demonstrably better from a performance standpoint, a developer experience standpoint, or arguably both.

Frameworks like SolidJS and Svelte simply got rid of the virtual DOM and reaped massive performance wins from it. I find it hard to believe that adding a worker and a virtual DOM back would end up making them faster. Quite the opposite in fact.

Then there's the dev experience. Would it be easier for a developer to work out what to do in a separate thread and post messages back into the UI thread? Seems like extra cognitive overhead to me.

Ideas are great. They move the state of the art forward. But if your idea doesn't comport with positive results from testing, it's not useful. Intriguing, to be sure, but not useful.
For me rating volume can be a red flag. Any product that has over 1,000 reviews and isn’t something has been on the market for years, I automatically deduct a star or two in my mind. People just don’t leave legitimate reviews at that kind of rate
It can be projection and also be true, if the author is more or less typical of people in the group they're projecting onto. It certainly resonates with me and a lot of us here on HN (which has been a hub for this kind of story).
For what it's worth, sapiens was generally hated by academic anthropologists but Dawn of everything is generally hated by everyone else. Graeber was always expressly advocating for one specific (anarchist) viewpoint in his work, and that book suffers mightily for it.

Don't take anything in that book as true, because I've read lots of academics losing their minds over how much he glossed over or just ignored contrary evidence.

What do you mean "to deal with"? There's a lot of misconceptions about marriage, having to "manage" your spouse is one of them. You don't, they're their own person, they can take care of themselves, and if they're dependent on you it's not a healthy marriage.
then you must have some learning disability because it was very well written. if i were to explain it to someone, i would say that the main idea was that you have two parties, two houses. you walk into the other party's house and simply let them explain their reasoning to you. you are indirectly confronting them. and by letting them do the talking, they have to back up everything they are saying, which leads to "gotcha" avoidance and makes the other side slowly chop off their demands that are not based on the truth until you get to the core of their wants or needs without all the fluff and glitter around it. if the other party would be as good in negotiating as you, they would then come into your house and let you do the talking, exposing your bs, not just theirs. but since that does not happen, you end up victorious, in a sense.

I for one am glad I went to University. I was exposed to topics and classes I would have laughed at earlier (philosophy, for one), met a lot of interesting friends, and had a really, really good time in general. In fact, I'd say that those years were some of the best in my life.

My only regret is that I didn't go on any exchange program. Really should have done that.

I think that if you only view higher education as a ticket to a better paying job, and nothing more, college could suck. But that's also under the assumption that you actively avoid social activities, and only go there to get your degree.

I really miss the youthful naïveté - all my peers were really motivated to do things.
There's a key point missing from most of the discussion: "In the USA".

Also, whether or not it's the choice of the doctors is only tangentially relevant to whether or not it's a failure of the system. Even if money is the only consideration, I'd question whether the system as described is the most effective. Ultimately, a US-based medical administration bills on being able to show that they've done things that they can justify having done. Hobbling the doctors' capacity to actually carry out work impedes that process, regardless of any questions around medical effectiveness.

And of course, "going digital" doesn't strictly imply moving to a broken system either.

This is a weird comment. There is no reason to expect that a hypothetical economically viable fusion power plant would have an unusually good "power generation to physical footprint ratio". At the same time - you really don't consider "uses water as fuel" an advantage?
Could you explain what this "infowar" is about, who "they" are and who is supposedly crazy and dumb?

Your post makes zero sense without context.
It achieves it by not needing React, etc. IMO. That is the benefit. It might be worth it or not depending on the project.
"local minima" is entirely a function of what processes and requirements are in place for code to be accepted. In a well designed engineering org, the "local minima" and "optimal" are indistinguishable from each other, because you only let through fully tested code that passes the hopefully many CI steps you have and has also been subjected to extensive code review, QA, etc.

If the reviewers and QA folks are doing their job, nothing like what you're describing should get through, and true "problem" engineers are simply those who are never able to get something through.

When this falls apart it is invariably leadership's fault for writing bad tickets or not implementing proper CI, quality control, or testing practices, or not allocating sufficient time and resources to the code review process.

And this stuff is only becoming more important as we integrate LLMs into our workflows...

It costs them $0 because consumers already expect a touch capable screen for infotaintment.

Yeah it's a dream. Anything touch is annoying to use when driving. MFD-like also have advantage of being able to be touch typed, once you know in which menu you are it's always same sequence, and as those are physical buttons it's far harder to miss-press something.

The tendency among the tech community is to think expertise and intelligence applies across fields, its the perfect Dunning-Krugar trap. He was drunk as hell, and adamant he knew more then the police. Everything follows from that and his twitter rants that night about how he's 'a white man-- not a n**ger' and talking about how much money he made just reinforces that.
I am working on a LEGO-like News Feed that allows you to combine different AI models and Filter/Ranking Blocks to create your own For You feeds. You can take control of the algorithm and iteratively train your algorithm on the data you specify. No more black box feeds that try to optimize you into mindless scrolling.

If you have diverse interests (say Tech vs Games vs Traveling), they can each be contained within their own feeds and your recommendation signals will not be polluted between the different feeds.

I find it frustrating you casually ignored the primary context of the comment/thread you're replying to, namely: suitable targets for GC (garbage collected) languages, not for C and C++, which you surely know are not garbage collected. WASM is a suitable target for Emscripten. But I never said otherwise, and this was not the discussion.

Also.

WASM is not "just another ISA" at all, as I explained in other comments throughout. For one it has an opaque call stack and no free jumps inside from one code location to another, unlike any other ISA in the world. This means it's terrible for languages which lean heavily into tail calls and coroutines, among other. It's also bad for GC languages as a custom collector can't compete with JS's GC.
