I think hydrogen will definitely be a “feedstock of the future”. It’ll be critical for green production of many materials and fuels.

But there’s no reason to use hydrogen if you can produce and use other green fuels with good efficiency. Hydrogen is hard to handle, leaks easily and has bad volumetric energy density.

But it’ll take time to develop methods of production and fuel cells for fuels like methanol, that are efficient enough that it’s worth the extra cost over just using hydrogen. So in the near time there’ll probably be some niches for hydrogen.

But in the long term, considering that hydrogen is completely unviable for large scale long distance shipping (the shipping industry is looking at ammonia for that) and long haul flights, and that hydrogen is unviable for ground transportation in the long term (batteries will clearly win there), I think economies of scale will push out hydrogen fuel in favour of whatever the shipping and airplane industry ends up using.
Years ago I worked in the industry and I totally agree. Fair Isaac in particular has enormous power as basically the only source of models people use, and they are very opaque.
Less than 70% on non-commercial structures. And on commercial structures the roof can be a negligible percentage of the total building envelope.

This is cool stuff, but it’s just stuff. It’s not a silver bullet. We here are all old enough, many of us by half, to no longer get sucked in by magic thinking.
We do have multiple robbers competing to break into our homes. We keep them out with locks and police but first of all we don't let them in and sit on our couch with us. I do have an Android phone and tablet. I use as little Google services as possible and never logged in, unless I have to as in the case of the Play Store to keep apps updated. But I don't buy anything from them and I install more and more from F-Droid.
> I really wish there was a better alternative to golang because it comes so close to greatness: fast compile times, small binaries, GC, great concurrency ergnomics, great for networking (My God! you can just use net/http for so much - it's insane), an attempt at simple code (yea checking err is boilerplate, but it makes error handling clear), a community focused on having few dependencies where it's possible to build something and have it work for years

It’s called Java
Reflections alone would be one of the most impactful additions. And in contrast to most others: very difficult to do otherwise. I'm a bit surprised by the sudden push after long phase where it seemed like they would never come.

Contacts: yes please. Variadic indexing is one of those things everyone writes their own helper for. But this standard facility is very welcome indeed.

Some additions seem a bit of of scope for the standard of a language that famously refuses to fix mistakes. So in weary about std::hive, networking, physical units.

And an underrated cherry is at the end: cleaning up those "ill formed, no diagnostic required" clauses in the standard. For those who don't know: there are things forbidden in the standard which the compiler is allowed to not tell you (because it's difficult for the compiler to prove it). In particular this is omnipresent in the constexpr world. Leading to silly redundant code that manually assets things to explicitly trigger the compiler to check for errors.
Ask HN: Is Google Apps Script still relevant? Any recent projects?
I haven't heard anything about Google Apps Script for a very long time.

What exciting functionality/projects have you built with it recently?

I'd love to take a look at the code.
"Elixir in Action" by Saša Jurić. The first and second chapters are excellent. However the third chapter (on Control Flow and Pattern Matching) isn't as well written, apparently it is important to know that Elixir doesn't assign values to variables but rather 'binds' the values to the variable. It feels a bit like having 11 on a volume knob.
There is also a talk on the M68k backend in LLVM:

At least it isn't PHP.

And it begat JSON, which is nice.
I've come to realize that I do need a social structure, but somehow I've managed to not keep friends. Maybe even not have friends until recently? I don't know. The word friend is nebulous, and I tend to qualify friend as someone I would help bury a body. I only have a few of those now.
I like writing markdown docs with mdbook, though I've never used it for something to be printed physically so I dont know how good/bad PDFs or epubs would come out.

What I like about it is that its easily extendable. You can write preprocessors to give yourself new features or an entire backend/renderer to render the book differently. I've written a very simple one myself.
Musk as Twitter owner doesn’t seem to pay much mind to research and a subdued approach to product development.
Are you referencing like pure nicotine liquids? Yeah vape juices that smell like jelly donuts, if a toddler/animal drinks a month supply in a few minutes it’s going to be bad news. Also, when people were mixing their own juices they’d be buying pure nicotine and getting poisoned.

“The dose makes the poison.”

Anyways, not going to list out all the pros and cons of nicotine as Andrew Huberman did that for us. He has a decent podcast that’s goes through it all.

No one really argues that it’s essential or beneficial in every way but it’s not the purported demon that the anti smoker lobby has made it out to be.

Many years ago, I heard the Japanese even put it into their drinks. I’ve tried searching for it now and found some iffy sources and outdated Reddit links and everything else is just e juice vape spam. Can any Japanese knowledgeable people confirm or deny this?
Yes I'm surprised the author didn't manage to find an artist or track with an SQL injection - surely someone must have tried
I don't think I've had a checked bag permanently lost since the '90s, though it seems like half the time I return to my home airport with ski equipment, they fail to send it out to baggage claim. But then they deliver it to my house a day or two later.
You’re missing the point here. Almost willfully so.

Two pieces of this material in an overlapping field of reflection are putting out exactly the wavelength the other will absorb. I can’t defend my building from being baked by yours by coating it with the same stuff. I am simply going to return the favor in the process.

Not to mention the big problem of creating a new case of the haves versus the have-nots.
One of things about Firebug in particular was how you had one thing like a DOM node and you could inspect it in different ways. Like the element panel or an object inspector in console. I worked hard to open this to extensions as well. And it worked for subpanels as well. Maybe I’ll offer up a patch for chrome devtools, but it’s been a while since I’ve made a PR there and it was pretty modest.
Yet another reminder that account recovery is the weakest link in the security chain for online accounts. Consider all the work going into new tech such as passkeys -- none of it matters if it's possible for janky account recovery techniques to punch a hole through flawless authentication standards. Unfortunately, companies have come to expect that a large number of their users cannot be expected to reliably store and retrieve their login credentials, whether in a password manager or their head.

It's certainly more tech heavy and a power fantasy, but I recommend you give Salvation by Peter F. Hamilton a read. Especially the first book has many layers, and has maybe the most intense "oh fuck" moment I've ever read. Peter F. Hamilton is incredible at creating coherent worlds.
Based on that, you might like "First Formic War" trilogy that are a prequel to Ender's Game.
Also probably mitigation of leidenfrost effect is gone after turning it hydrophobic.

Maybe it would be better to cover with something deadly to algae. Preferably not toxic. If there are such things. Silver nanoparticles?
I use WhatsApp and IG daily, but stopped using Facebook in about 2018. Didn't close or delete the account, just removed the app from my phone and stopped using it on the web.

I didn't like that Facebook kept showing me content I wanted to argue about, even if that was 'just' the opinion of friends. I'm very glad I cut it before the pandemic.

I stopped Twitter for the same reason. That said, I'll still use it occasionally, but mostly just scrolling individuals feeds. It feels incredibly toxic there as well, particularly with the suggestions and everyone being verified. Feels more like "trust no one", which is a shame.
Yes, and if you want to know a tragic fact, when they started the UWP to WinUI 3.0/WinAppSDK migration, that wasn't part of the initial efforts.

So as MAUI decided to have their Windows backend built on top of WinUI 3.0/WinAppSDK, their Maps component on Windows is actually a Web widget wrapping Bing maps instead of the OS provided Maps component.

This shows how well the GUI civil wars are going in Redmond.
Nope, because all the carbon production until that point can be unwound.

This problem is widespread in FAANG.

At the core, organizations want to align individual growth with organizational & business growth.

Because most of these companies run many businesses with wide varying nature of revenue impact, they've decided to use size of organization as a proxy for business impact. From my experience at Amazon, there's a process to acquire additional headcount where business leaders will assess your proposal and approve additional headcount.

However, most mid level managers now purely optimize for headcount with complete disregard for customer value or business impact. I think we're missing 2 things:

- Leaders who can discern whether some work requires X people or 2X people. The margins are not off by 10-20%, they are off by 200-500%.

- Feedback loops. I havent seen this talked about much in the tech circles yet. Once headcount is assigned, there's no further checks on whether original goals have been met. Leaders, managers & teams move on to find even more land to grab. If we had feedback loops around what that additional headcount has achieved, a lot of the empire building behavior could be curtailed.
Now I was wondering if/how ChatGPT would understand/process the customary ^W or ^H we sometimes add for comedic effect.

Excerpt of a 3.5 chat:

gpt[1]> write a sentence that contains red^Wblue

The vibrant red sunset transitioned seamlessly into a calming blue twilight.

gpt[2]> again

She wore a striking red dress that unexpectedly transformed into a mesmerizing shade of blue under the evening lights.

gpt[3]> write a sentence that contains red^H^H^Hblue

His initial choice of a red shirt for the party quickly turned heads—scratch that—blue, as he realized the dress code was more casual.

gpt[4]> again

The artist's intention to paint a red flower ended up as a beautiful canvas of blue, highlighting the creative evolution of their work.

gpt[5]> write a sentence that contains red and blue

She decorated the room with a vibrant mix of red and blue accents, creating a lively and energetic atmosphere for the celebration.

Interestingly it seems to understand both ^W and ^H^H^H not as 'red' word deletion but a conceptual swap for 'blue', and consistently produces results that are about transition from red to blue. This kind of makes sense as when we use that we do so to actually keep the supposedly-deleted word for subtext effects brought up by making explicit we redacted one word for another, but it feels like a category error to me, as if it did the right thing but at the wrong level (even the one with "scratch that", although it gets closer)

The last one is (one of a few, elided for terseness) prompts that I tried to cross check whether it was a coincidence: doesn't seem so as they all produced non-transitional results.

Can't test 4.0, wondering how it tackles that.
That reminds me that I have enjoyed all of Singh's books. But I recall he was sued for his last one and has not published in over 10 years?
Yes, this will work. Sometimes you do it to yourself and you want to ignore the line.
Even is also a common Norwegian name. Since you can have multiple first names too, you can be named Odd Even or even <sic> Even Odd.
What I like about the go.mod file is that it easily allows to remap go modules to local path folders.

This way I can have a backup of the dependencies wherever I want, even when not using "go mod vendor" (which I like also a lot tbh).

So I don't understand the critic in the article, you cannot solve this problem efficiently other than putting everything on a blockchain, which will waste a lot of hard drive space.
The biggest issue for me with OCaml is OPAM. It's pretty awful. Simple things like "install this code" don't work reliably - often installing a different branch or just ignoring edits you've made, even after you discover the flag that says it should include them (it seems to be simply broken). It also doesn't work on Windows in any meaningful way.

It's not just me that has these issues. We introduced a tool into my company that is written in OCaml and I ended up spending so much time helping people fight OPAM that I eventually implemented a build cache system so they didn't need to actually compile the OCaml code at all. Saved a bunch of hassle.

It seems like a pretty decent language, aside from the issues the author of this article mentioned which are 100% true. But OPAM means I would never pick it.

Similar issue to Python, which isn't really a bad language (I'd say it's mediocre-to-ok), but the packaging and tooling story is abysmal.

More languages need to learn from Go, Deno and to a slightly lesser extent Rust which have all prioritised having a packaging system that doesn't make you want to tear your eyes out.
I didn’t read either of your comments but I agree as well
> OpenAI has changed education.

No, it objectively has not. Maybe it has changed how you teach, but “education” is much larger than any of us. Until school curriculums around the world incorporate ChatGPT—quite the dystopian scenario—they have not changed education.

> Cheap ski equipment, Rolex watches

All Rolex watches have serial numbers and there's an official database of stolen and lost rolexes. A police report should be filled and sent to an AD (authorized dealer).

Knowing this allow righful owners to find their watches, selling found Rolex is... theft?

FWIW when travelling the customs may ask you for the invoice of your fancy watch (I always have mine in my wallet).

I somehow managed to read most of Children of Dune without looking up what a qanat is. Since then I've remembered it specifically for use in Scrabble, but over 20 years later I've still yet to get the opportunity to use it (I don't play Scrabble much any more).

To each their own. Like I said.
The neat thing about wearing white in the desert is that it keeps you cool during the day and warm at night. Wearing black does the opposite.

A perfect black surface on a spacecraft can do more than charcoal black paint, but only by a matter of degrees. If memory serves its less than a 2x multiplier between off the shelf and exotic materials. But when ounces cost thousands of dollars, you’re going to go exotic.
You're overthinking it.

But anyway, firefox has an option to delete history, cache, cookies. Settings/Delete browsing data.

If you are really paranoid, go to the firefox app page, storage, click clear cache, clear data (will reset to default)
Last week I finished "The Midnight Library" by Matt Haig, it's about having regrets for the things you did or didn't do in your life and how those things could have turned out if you made different choices, pretty good book.
Currently I read "Healing back pain" by John E. Sarno I'm halfway through and think it's interesting so far, yesterday I also started "Eversion" by Alastair Reynolds, can't say much about it because I only read 10 pages, but Reynolds' books are mostly pretty good.
Or even a hundred. The "singularity" analogy isn't one I favour[0] but the radical changes the idea represents would make today seem like a primitive ancient world to those that come after it.

If it's not for you its not for you, but pretending that a keyboard shortcut of alt plus a key is somehow an entirely different concept and outside the realm of alternative is pretty hilarious.
> On flights within the U.S., airlines are responsible for lost-luggage reimbursement up to $2,500 per person; on international flights, airlines owe you a mere $9.07 per pound, with a ceiling of $640. (That rate was set by an international treaty in 1929.)

> Beyond that, airlines owe you nothing for your most valuable items. Most contracts of carriage specifically exempt from compensation things like antiques, art, books, documents, money, cameras, collectibles, electronics, or "fragile or perishable items." [1]

Also this is not a guaranteed payout, you may need to provide receipts for your things [2]. In general I would prefer to keep the contents of my bag vs receiving "up to" $2,500. We're mostly working people here. The time and money cost of travel disruptions, replacing stuff, navigating bureaucracy etc. is not low. And my stuff has emotional value.

I agree that this setup seems reasonable in a perfect world. But knowing how large, complex companies function, I feel it is unwise to create any kind of loop which rewards airlines as a function of luggage lost.

The Millenium triology was published after his death. He never got to know how successful he would become.
Advertisers, they live in some deluded reality where there is no violence, no swearing and people watch TV all day but at night they don't exist.

This was a decision about some target group, I'm sure.
I think we should be asking how to design the procedure for when someone calls and claims they forgot everything and lost everything. An attacker can always call in and say this, and we'll need to call in and say this if we've been attacked.

My opinion: we should be able to visit a government office, get our picture and fingerprints matched, and then we can reset our email/password/2fa right there.

> don't understand why Chinese speakers don't put more [any] emphasis on using names that they are themselves able to pronounce, like Tina or Julie.

Some are assigned an English name by their first English teacher in school. This English teacher themselves may not really be able to speak English (e.g. this is the case for more than one person in my family). By the time they figure out otherwise, it's kinda stuck/habit.
I actually quit over the course of a week. Going from 10mg+ pouches down to 9, 6, 3 and finally quit.

Going from 3mg to no longer using was relatively straightforward.

Trying to quit from 10mg cold turkey was basically impossible. 4 days after going cold turkey I was still absolutely desperate for nicotine. The difference was massive.
Ask HN: Recommendations for Software Engineering Audiobooks?
I had not, this is great, thanks
Took a glance and it seems very interesting. Thanks for sharing! The first paragraph speaks with such truth as to universal education being an impossible but at the same time mentions some clearly far-left thinkers. Can't wait to read how he reconciles such seemingly opposite ideals.

Also, I know a story of someone persecuted by McCarthyism in the US went to live to Cuernavaca, Mexico. Did not know this was part of a broader pattern...
Still do and I used to enjoy it until just a couple years ago when the suggested content completely overran my feed. I don't know how they've managed to make the alorithmic recommendations so bad - they range from boring and cringeworthy to ouright offensive (like pages praising Putin for his anti-imperial efforts for instance). I've tried to be a good user and engage with that stuff just the way Facebook recommends - marking what I dislike etc., but no luck - it's still mindbogglingly awful. I've stopped posting and reading the feed and now only ever use it to comment on a single page.
Although it would be nice, nobody is under any obligation to go out of their way to return your lost property.
Then as far as you know, someone else has already done it in your name.
Has anyone understood why they keep bringing the leidenfrost effect in the discussion? I really don't know what this has to do with radiative cooling.
Every sale is, literally speaking, a conspiracy between buyer and seller to do a deal. A conspiracy doesn't need to be nefarious to be a conspiracy.

I think there is a lot more on the bargaining table between SpaceX and the US military than dollars, given the geopolitical implications of the level of easy access to orbit that SpaceX currently exclusively possesses. No other organization on Earth could cost effectively build something like Starlink today, due to F9 reusability.

Euphemising the X37B as a "national security asset" doesn't change the fact that SpaceX has historically only launched reconnaissance for the US military and not weapons (and that Musk had explicitly avoided getting involved in supporting weaponry, at least until it seems he no longer could).

This being a change to the status quo, of course, presumes that the need for FH indicates an X37B payload that is heavy (or an orbital insertion that requires more energy). Both of these suggest (but do not guarantee) weapons systems, either from payload weight requirement or orbital insertion requirement (or both).

This is, of course, an assumption, and it's possible that SpaceX still hasn't committed to launch any weapons, and that the X37B is just heavier because of its research payload(s) (or it's also reconnaissance and they just want to put it in a specific big-delta-v-requiring-orbit for better surveillance).

It's also possible it's chock full of munitions and SpaceX doesn't get to keep trying to research how to get to Mars if they don't help the US military continue to do what they do on Earth.
I sure would not have bought from you, as it's a stupid idea to buy from someone inside a club where it very well may be the case that the seller did not do quality control. For me, that would have been the part to feel bad about: "How on earth could I put other ravers lives in danger by selling pills that I have not had tested, and that could contain pretty much anything?".

I also agree that MDMA can be a dangerous substance of course. Far less toxic than alcohol, but still.

But compared to this, ending up in the US jail system carries FAR bigger risks. As you said: It could have ruined your life. It could also have ruined the life of people who bought from you, as they could also have ended up getting arrested.

I really can not imagine a drug available that will do worse things to your life than ending up inside the US jail system.
This could be very interesting material for surfaces in greenhouses where you want to have as much light as possible but during the summer don't want to have the heating effect.
Just tested it. I hummed 'Frère Jacques, frère Jacques Dormez-vous ?', a common nursery rhyme in english-speaking UK, despite being french and not many people here speak French well.

However, Google gave me 3 results, none of which were in either English or French. They were Spanish and Italian (I think!), and both had the correct tune, but weren't what I was looking for.

I wonder if the search engine could better handle this case by recognising cases where lots of songs use the same tune, and showing results for the ones which are most popular in the region the searcher is searching from?
Used to use Alfred app’s clipboard history, but recently I’m moving everything to Raycast. But couldn’t figure out how to paste second item from the history with a shortcut key, other than that Raycast is pretty good.
