Two possible scenarios come to my mind, but both are a bit far fetched. First one being that this is some kind of phishing training & seeing what kind of techniques could be utilized when doing attacks against high-value targets later (or maybe even being a "final test" in some phishing course for some of the more professional groups (those that are run by nation states)).

Another one being that they are doing it to obtain blackmailing material. Maybe they are hoping that there are things in some of the drafts that could be used to blackmail the author (e.g. in some cases there could be things that might be considered to be racist/sexist/similar, but would normally be caught by the editor).

The abstract of the paper makes it sound good:

>Overall water splitting, evolving hydrogen and oxygen in a 2:1 stoichiometric ratio, using particulate photocatalysts is a potential means of achieving scalable and economically viable solar hydrogen production. To obtain high solar energy conversion efficiency, the quantum efficiency of the photocatalytic reaction must be increased over a wide range of wavelengths and semiconductors with narrow bandgaps need to be designed. However, the quantum efficiency associated with overall water splitting using existing photocatalysts is typically lower than ten per cent1,2. Thus, whether a particulate photocatalyst can enable a quantum efficiency of 100 per cent for the greatly endergonic water-splitting reaction remains an open question. Here we demonstrate overall water splitting at an external quantum efficiency of up to 96 per cent at wavelengths between 350 and 360 nanometres, which is equivalent to an internal quantum efficiency of almost unity, using a modified aluminium-doped strontium titanate (SrTiO3:Al) photocatalyst3,4. By selectively photodepositing the cocatalysts Rh/Cr2O3 (ref. 5) and CoOOH (refs. 3,6) for the hydrogen and oxygen evolution reactions, respectively, on different crystal facets of the semiconductor particles using anisotropic charge transport, the hydrogen and oxygen evolution reactions could be promoted separately. This enabled multiple consecutive forward charge transfers without backward charge transfer, reaching the upper limit of quantum efficiency for overall water splitting. Our work demonstrates the feasibility of overall water splitting free from charge recombination losses and introduces an ideal cocatalyst/photocatalyst structure for efficient water splitting.

Not so sure about the fuelcellsworks article clickbaiting up the 'quantum' bit when all it means is one photon splitting one H2O.

This is a fantastic quote - you could write whole essays on how it relates to open sourcing a software project.
There is a general definition that you will find in dictionaries and that is generally accepted. So I think there is a definition that everyone agrees on when there are not pushing an agenda.

Then there is the use of the term for rhetorical and political purposes... This is what obviously varies according to the interests of those using the term. Obviously the terrorists are always the 'other guys'.

Note that the definition I gave, which is nothing more than the Oxford dictionary one, includes a crucial word, "unlawful". This is very important to differentiate between warfare and terrorism. A sovereign state uses violence for political aims, this is warfare and it is 'lawful' (it may be unlawful under international law, though). This is why action by nation-states are usually not labelled 'terrorism'.

It is going to be very costly (energy and capital investment) to convert steel making to use hydrogen. A blast furnace is a well balanced chemical reaction where the coke serves two purposes; a source of carbon monoxide for turning ore in iron (Fe2O3(s) + 3 CO(g) => 2 Fe(s) + 3 CO2(g), very exothermic, good for turning the iron / steel into a liquid alloy), and a source of carbon for turning the iron into steel. All in one vessel and in one process no less. I guess you could do the first step using peroxide to strip the oxygen from the iron, but the second step in the same vessel at the same time?

Fe2o3 + 3H2O2 => 2 Fe + 3 H2O, somewhat exothermic (if my rusty memory of enthalpy calculations are correct), not sure of the activation energy or need for catalysts).

[EDIT] also forgot the peroxide reaction would probably require external heat to over come the latent energy required to turn the H2O into super heated steam so that you could melt the iron / steel. This would probably boil off a large chunk of the peroxide as well, so it might need to be done in a contained pressure vessel, which would probably affect the speed of the iron ore reduction.

Is there any research about memory efficiency of spoken languages that is collaboratively conducted by neuro and computer scientists?

This may sound a little weird (and even stupid since I'm no expert in any of these fields)question, but it keeps my mind busy, occasionally. I tend to think there should be different "memory footprints" of languages - like languages with phonemic orthography[0] has much less memory footprint than non-phonemic ones.

The OP was asking how people might watch a video like this, not who is watching it. In 1937 broadcast television was relatively new and few people owned a tv. For example, the wikipedia page for TV in 1937 notes that by the end of that year 2,121 TVs had been sold in England:

Let’s say we got strict on the “phone book” idea: that advertising was only allowed on your own storefront and in a central directory. My point is not about whether businesses should survive (that’s a whole other topic), but more that that businesses would start to try to exploit those two avenues. For example:

- Buy the largest storefront in the most visible area, even if all you have is one product

- Create a shell company that creates directories, position it as “the best directory for <your industry>”, charge bleeding-high prices then give yourself adspace for pennies

- Good old fashion bribery: pay the lawmakers 10mil to put in a clause so that you’re allowed to advertise “in the header of your own site”, then buy a bunch of industry sites

Zyxel tried to add a function where THEY can access devices over the internet and do who-knows-what whenever they wanted.

And they did such a poor job of that, that they managed to give access to the devices to everybody.

This is actually not-too-dissimilar to the story of scurvy in European navies in a more distant time. It took a lot of lives and most attempts to alleviate it were based on the totally false theory of humors.

> if you give everyone a fixed amount of money, won't the cost of things just rise accordingly?

I hear this argument a lot but I don't think it necessarily follows:

- The supply of low end goods (the sort which you can afford with your UBI) is highly automated and will increase rapidly for any small price increase, making their pricing fairly inelastic.

- The demand for these goods won't rise greatly (except for low end luxury / status items, for which UBI makes the difference between people buying and not) since anyone living above a subsistence level is already buying roughly as much as they need (they're just feeling more financial stress now by doing so).

So overall I'd expect we might see a small price rise but nowhere near enough to cancel out the UBI.

Yeah, it seems clients are lagging behind with this. Visually marking emails which are from new domains or addresses is a nice idea.

The From header should be much more prominent too.

For example, perhaps a user should be presented with the email address in large text and explicitly asked to “trust” it before viewing emails for that address (similar to SSH).

People would probably get fatigued of that and click through though, of course (similar to SSH... although it’s much easier to quickly check whether an email address is as expected compared to a SSH fingerprint).

B2B companies of HN, how do you communicate with each other privately? I'm struggling to find a secure communication medium.

Setting up PGP is annoying and also requires recipients to have it.
Emails are clearly not private.
Whatsapp, Messenger, Signal and Telegram are a bit personal (most require a phone number, and companies don't provide phone numbers to all people). SMS/ phones are also not secure.
LinkedIn premium is expensive monthly and doesn't provide a good messaging UI.

Oh, the reason why I ask B2B specifically is because consumer products can communicate through their platforms where users already have accounts. Their either enmeshed in platforms or have their own platforms.

That would explain the abundance of available mini-models that they could machine.

That does take the wind out of the sails of the argument that it could've had a broader focus than just the differential engine.

So calling it out here in such a uselessly rhetorical manner isn't some logical fallacy flag, it's a derailment of the discussion.

This deserves a longer reply. List archives get lost as well, if they were available at all. I do agree that deletion rights given to maintainers is a stupid idea, it's very prone to misuse. But mailing lists also have that, maintainers can simply block e-mails reaching the list. At least with deletion people subscribed to new issues will always get them (in the case of GitHub).

What’s really funny is that if you go to Amsterdam, you can get paracetamol in a quick dissolving pill that works much faster than the really hard ones you get in the states, but it’s in a bubble package and fewer doses so it’s harder to commit suicide with.

So.. we don’t care if you kill yourselves, as long as you don’t have any fun doing it?
Terrorism: Non-state and/or extra-judicial use of means to induce perception of collective insecurity ("terror") in order to achieve specific goals.

Basic categorization of terrorism then would be concerned with:

a: tuple (agency, means)

must resolve to be "illegal" within the applicable legal scope. For example, a state dropping bombs on a civilian population (nation-state, war-crime) satisfies the above requirement but doing the same to enemy soldiers (nation-state, warfare) does not. Same with a private group blowing up a bank (ngo, crime).

b: tuple (target, reacting-agency)

Goal is to use terror in the target to induce the reacting-agency in responding in a desired manner. If there is no reacting-agency (and thus no goal) it is not terrorism; it is merely pathological.
It's not clear that this phenomenon (if it exists) has anything to do with the relaxing of educational content norms. If anything, the technological advancements caused by that 'sense of duty and progress' have led to a reduction of the average 'Western' attention span to the point of requiring reductive and trivially engaging educational media. That's probably not really the case either, but it seems just as valid of a theory without considerably more rigorous investigation.

> If it knew, it wouldn't have to contact anything in order to update itself. It would already have known.

Eh? That's how most package managers work. They only issue a very small number of commands to put them into an "updated" state. They don't generally do arbitrary things.

For example, if we take a look into aptitude, the deb packages it eventually fetches after running various authentications, contains:

+ A directory listing. (Contents-<arch>.gz)

+ Paths and checksums. (Release)

+ Signing information.

It doesn't have an arbitrary listing of commands to put it into the "updated" set - that's already decided by the format. The machine _does_ know the sequence of actions that is necessary. You don't need some kind of Turing complete monstrosity that can do absolutely anything to update it.

In the case of a _firmware update_ that's even simpler! Most of the time you're either replacing a kernel, or flashing the firmware to a pre-decided memory address. Both of those actions are decided long before you even begin issuing updates.

The person creating FOSS object that other people find so highly-valuable they voluntarily pay for it is performing at least as much a trade as the person working a regular job for pay.

It is not right to characterise that form of making a living as being handed anything. To achieve that is hard work and just as much a form of trade. The voluntary nature of payments for the objects implies they are more valued by others than ordinary trade where payments are mandatory and creators can "coast" with lower quality products.

Arguably the person doing a regular job for pay is being handed more, as almost anyone can work a basic job for pay and gets the fruits of everyone else's labour. It's almost a freebie in modern society: Do some work get vastly more of what you need for a good life given to you while you produce maybe 1% of it yourself.

From this perspective, a job is 99% handout from the collective to you, 1% contribution from you to the collective.

Are we sure that we aren't biased towards google due to familiarity? I started using google a long time ago before bing was even a thing and now I know that i use google mainly due to inertia. The weird thing is over the year my searches have gotten much more narrower, and i usually end up viewing results from reddit, amazon, stackoverflow and a hand full of megacorps. I'm really not even sure how hard search is when most of the information people want to see is concentrated in a few websites. Google used to be a lot more useful back in the day when i would scour page after page looking for information from obscure one off websites.
