> Fuel cells, at least in large installations, can already reach 85% efficiency or battery (assuming heat recapture).

Heat recapture is great, but we care about electricity output.

> Finally, as the economics of hydrogen production scale up, we can expect cost to approach zero. That’s because it is very much like wind and solar: We’re using a basically free resource

It will never reach zero because the equipment, transportation, and people involved are not free.

Further solar panels and wind turbines got cheaper due to learning effects. These effects are not present for over half of the things involved in a hydrogen fuel system. Pumps and tanks and valves and pipes are already mass produced.

And while the sunlight might be free, the electricity from it is now, and never will be since the equipment isn’t free.
Ha, glad to see I'm not the only one. LaTeX math is great, the rest should be thrown out. Something like Asciidoctor is perfectly fine for creating “serious” documents and supports LaTeX.
In recent weeks they've started inserting interstitial ads for other BBC content at random points inside In Our Time.

"How can they do that, the show is an uninterrupted 45 minutes of talking" you might ask. Well, they just insert it at a random point somewhere, possibly halfway through a sentence. It's both very annoying and amateurish.

>when you learn how to program it

I don't know if you mean, like, LoRAs and similar (actual substantive changes), but the vast majority of "learning how to program" LLMs (accounting for the majority of startup pitches as well) is "prompt engineering" - which, as the meme goes, isn't a moat. There's a skill to it, yes, but if your singular advantage boils down to a few lines of English prose, your product isn't able to control a market - and VCs are (rightly) not interested unless you have the possibility to be a near-monopoly.
> Like google has strip mines the internet and left a toxic pit behind

Can you clarify what you mean? I think there's a sense in which sometimes people say that google ruined the internet b/c (a) their prominence and their algorithm induced the creation of awful content farms, and (b) they pulled ad revenue away from some businesses that create content leaving us with a more impoverished web experience.

If you're making a different kind of assertion, please elaborate on it.

Wrt (a), I think site owners that had useful content weren't for the most part pushed to remove it, but were often pushed to pad it to the point that it feels less valuable to users (like recipe sites where every recipe is 12 paragraphs of prose before the actual recipe, IIUC), so I think this still fits in with the "dilution" framing, rather than removing valuable material in a way that excludes others from its use.

Wrt (b) I do think that when google displays content on the search page in a way that stops most users from continuing on to the page from which the information was sourced, that does seem effectively extractive. But I think that's distinct from the OSS project-capture problem.

> if companies have their way they'll do the same to any captive open source project, turing any public parts into nothing but minimum viable bait to try and get people to pay for something.

I actually think google is a good illustration of the full spectrum of OSS projects. They're definitely "getting their way" but:

- gson, guice, protobuf, snappy, the go language are all examples of projects that are very useful and pretty separate from any revenue-generating google product

- kubernetes, istio, etc are projects that can easily be used without touching any google revenue-generating project, but if you're using some of their revenue-generating projects, you may likely want something like this. Perhaps this is OSS but writing for your paying customer-base as a target audience?

- android, chrome, tensorflow are all about building little googleverse of customers in their orbit

In the LAMP + jQuery days, it was harder to build very sophisticated apps but the big advantage is the stack was very simple. Not only simple to build with but also to maintain. We basically lived in the AK47 era.

You seem confused. The very first complaint in the big post you responded to with "Literally all of your concerns are 100% solved by adding a log bot to the channels you care about" was this:

Are eIDAS identity services even interoperable for private service providers? AFAIK public service providers use national portals that aggregate identity providers, but private service providers must have a contract with identity providers.

> But since nobody became a billionaire out of it, nobody talks about it

Here in CZ, the law was setup in a way that gives advantage to banks compared to other identity providers, these banks created one consortium, which is essentially monopolistic provider, with ~80 % market share, asking private services providers significant money for identity services.
> You really need to factor in a literal 6-10x lifespan difference into efficiency and environmental impact figures, too...

I would love to see energy efficiency regulations take the item's expected lifespan into consideration instead of being a mere "energy per hour" measurement.

One simple/naive way to do it would be to divide (energy per hour) by the number of years on the warranty. Your warranty is for twice as long as the other guy? Then your device can use 2x the energy.

Obv, this would require the warranty to be a "full" warranty, and not something manufacturers can too easily weasel out of.

Hydrogen becomes more attractive once electricity is decarbonized. It's really the only fuel that has both the energy density to power flight and transoceanic travel and does not emit carbon. Batteries are fine for cars, and trains can be electrified. But you'll never fly across the Atlantic on a battery powered passenger plane.

Synthetic methane and other hydrocarbons are also ideas that are floated. But those need hydrogen as an input anyway. They also need a source of carbon, which is too difficult to extract from the atmosphere. So using the hydrogen directly may be more feasible.
Agreed there are multiple definitions in the US, and the term is very murky. As far as I can tell, the people who fixate on identity stuff usually identify as 'progressives', although some who identify as 'liberals' might go along with it because that's increasingly the new moral orthodoxy on the US left. Of course, many conservatives often refer to the entire US left as "liberal" (in the same way that many progressives call everyone to their right "far right").

Incidentally, if you talk about liberalism people are more likely to understand that you mean the philosophy rather that some basket of policies and jargon that are popular with the liberal tribe at the current moment.

> broadly call myself a feminist or anti-racist

Even these labels are fraught, at least in the US. They are pretty much doublespeak insofar as the folks who identify as 'anti-racist' in the US tend to endorse policies that are explicitly racially discriminatory (they would say 'race conscious', but they mean exactly the same thing), and the folks who identify as 'feminist' in the US have no discernible interest in gender equality.
That’s what I was thinking, yes.

You have to think HOW you pronounce the word. The ‘u’ in “unity” is pronounced as “you” which starts with a consonant. Hence, you use ‘a’ not “an”.

China is an evil empire.

What to do about it without starting World War 3? Here are some of my ideas:

- Heavily tax or cut off business with them, with an explicit linkage between specific evil behaviors and the monetary costs / damages to Chinese businesses. They don't understand morality as we do, or they wouldn't do this kind of crap. But they definitely understand dollars and cents. And if their trading partner is willing to make sacrifices to hurt them, maybe that will be enough incentive to change their ways.

- Talk about it. This should be in the national news, addressed by PotUS at international events, and so on. Most people realize this is evil as soon as they hear about it. So the more people find out about it, the more people will rightly be horrified, and the greater chance they'll have enough collective power to stop it.

- Support Taiwan. No more of this "maybe it is, maybe it isn't" hand-wringing. Say explicitly "We decided Taiwan is the legitimate government of China because the CCP is too evil to be in charge of a corner supermarket, let alone a country." Yes, China won't like it. That's the point: The only way you can get someone with no moral compass to not do evil things is by implementing unacceptable consequences for the evil things they do.
I agree citing scientific sources fortifies an argument, but I would advise you to take anything on Wikipedia as an unreliable source.
Wikipedia is not a reputable source unfortunately.

Here are a few reliable sources you can look into for information about climate science and climate change:

Websites:

NASA's Climate Change and Global Warming website (https://climate.nasa.gov/) offers an extensive collection of data, interactive features, and explanatory articles.
The Intergovernmental Panel on Climate Change (https://www.ipcc.ch/) produces comprehensive reports about climate change.
The National Oceanic and Atmospheric Administration's Climate.gov (https://www.climate.gov/) provides climate news, data, maps, and more.

Books:

"The Uninhabitable Earth: Life After Warming" by David Wallace-Wells: This book offers an uncompromising look at the potential impacts of climate change if left unchecked.
"This Changes Everything: Capitalism vs. The Climate" by Naomi Klein: Klein makes a case for how addressing climate change requires major changes to our economic system.
"Climate Change: What Everyone Needs to Know" by Joseph Romm: This is a clear, concise primer on the key aspects of climate change.
"The Sixth Extinction: An Unnatural History" by Elizabeth Kolbert:This Pulitzer-winning, discussing the ongoing mass extinction driven by human activity, including climate change.
"Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming" edited by Paul Hawken: This book compiles and evaluates solutions to climate change.

It's worth mentioning that understanding climate science also involves learning about related disciplines like chemistry, physics, and earth sciences, so exploring resources in those areas may be beneficial as well.
Good luck!
Yes, a genuine question.

We're actively trying to move to a 100% open source tech stack (Super hard to do).

Hence trying to see if there are any Open source tools we have missed out. There are many alternatives the community has mentioned that would have been super hard to find out otherwise.

Thank you for the search recommendation previously, that helps too.
Great recommendations! I'd pick The Genealogy of Morality as a better intro to Nietzsche, tho my favorite is far and away The Gay Science.

I wouldn't pick Meditations as being a intro classical philosophy tho, the Stoics were very much their own school of thought, and not the primary one that carried forward into later eras. It's a fascinating school of thought, but more also a diversion in getting up to speed (another great side-path from the same era is Pyrrhonian Skepticism!). Aurelius is also really late chronologically (and frankly not a philosopher at all... The modern equivalent would be a celebrity publishing a self-help book, still an extremely fascinating historical document tho).

I'm a huge fan of the Alan Bloom version of Plato's Republic. But if we're getting specifically into Plato, I'd feel remiss if I didn't mention the Euthyphro too.

There is also a _lot_ to be said in favor of reading the history of philosophy in rough order. It's a conversation through the millennia, and you can't truly understand what an author is saying unless you understand the context they are replying to. Eg. Kant is frankly unintelligible (and subject to wild misinterpretation) unless he is read as a rebuttal to Hume's continuation of Descartes's protect (as Kant himself says in the intro to the first critique).

Re analytic philosophy: In the words of my thesis advisor "breaking philosophy down into the categories of analytic and continental is like breaking down cars into the categories of those-with-four-wheel-drive and those-made-in-Europe".
> otherwise you'll have to invest a ton of time into many different people and you don't have that kind of bandwidth.

but who is investing this time and bandwidth?

It seems like this sort of governance model allows politics to replace egalitarianism or meritocracy. I could have become a Debian contributor/packager many times over, but it always seemed not worth it for a thankless job which is mostly dealing with bureaucracy and red tape instead of actually solving technical matters.

(To be fair, I've since moved on to Funtoo, which, like Gentoo, is very egalitarian -- but requires a certain, rather high, level of technical interest and expertise which is its own filtering function. On the other hand, Debian's packaging policies are very strict, and many distributions have much less strict packaging policies.)

How do the less-difficult distributions such as Arch or Alpine do it with less overhead (and is that better or worse?)
I think you're confusing proteins and carbs. Dietary fiber yes a carb is not a problem as the body typically does not process dietary fiber. You need some carbs in the diet, but have you ever checked the nutritional label? Sugar is a carb. You really only need so much carbs in your diet and that is about 100g to 200g.

It's amazing to me that in 2023 when the small-package industry (USPS, UPS, FedEx) is SO SO SO highly optimized that I have a choice of 3 carriers to get a box across the country in 1-2 days and by and large it works pretty darn well, and yet if a company wants to ship a pallet the same place, the logistics fall apart into garbage "it'll get there when it gets there."

I know FedEx and UPS offer freight services, but it doesn't sound like they're dominant or close to it in the industry.

Yes. If it is sufficiently original to be a distinct work (most human translations will be), it is a derivative work with its own copyright; if it is, e.g., a purely mechanical translation, it is covered by the copyright on the original.

In either case, without permission or a copyright exception (e.g., fair use) it is also a violation of the original copyright, either as a derivative work or a copy.

Pretty good overview from Baldur — I don't always agree with everything he writes but this seems relatively correct.

One question I'd ask him (and anyone else reading) is: what are some other options for monetization?

Over the last few weeks I had three different VCs reach out to me about some of the open source projects I've been releasing, and ask me if I'd thought about making a business out of them. I told them that no, based on the problem the software was solving, I didn't see how I could adopt open-core or companion-saas business models, and I wasn't sure how else it could be done while keeping the code open source.

Can anyone suggest a viable business model that would allow:

* Code remains at least source available, ideally open source for non-commercial use.

* I can charge for commercial use.

* Actually doing the licensing is reasonable, ie no spyware or phoning home from the tool.

Wouldn't need to be perfect, I understand that if the code is open source a company could easily fork and use it without paying me. The idea would be to make it zero-headache to pay me for a license if the code is being used by a funded team.

The projects:
