jfk13··on Desalination system could produce freshwater that is cheaper than tap water
According to a quick Google search,

> On average, about 35 g of salt is present in each 1 kg of seawater

so if those 700 billion kg of water for LA all came from desalination, that would yield 24.5 billion kg of salt.

That suggests we could have 12 LA-sized cities relying entirely on desalination before we'd saturate the world's demand for salt.

jfk13··on The Tao of Programming (1987)
I guess it's no more insensitive than writing a book titled "The ___ Bible" (for your choice of language or topic... there are plenty of examples).
jfk13··on FEMA and FCC Plan Nationwide Emergency Alert Test for Oct. 4, 2023
I suspect that if you distributed emergency supplies ahead of time, some people would treat it as a convenient handout and simply consume them.

And even aside from the temptation to use the supplies, not everyone would be able to find a place to store a month of rations & water.

jfk13··on ‘Less than half’ fresh produce sold globally makes any profit
This sounds uncomfortably like a call for more of the consolidation and industrialisation of farming, in the name of efficiency, that has been devastating to our environment.
jfk13··on DeepMind cofounder: Generative AI is just a phase. What’s next is interactive AI
Yes, indeed. If I read a history book about Charles Darwin, I'm generally aware that I am reading a particular author's portrayal of the man, his life and his times -- and that there are other books about him that may give a different slant or interpretation.

But in 10 years, when intrasight "sits down in VR for a deep conversation with Charles Darwin", there's liable to be an unspoken assumption that the interaction is somehow based on a "reality" that in fact is unknowable.

> with any historical figure

Don't you mean "with a fictional representation of a historical figure"?

jfk13··on Client harassed by The Type founders for using Proxima Nova font on website
> Website Publishing: Create a Web Project to add any font from our service to your website

It doesn't say "...add any font from our service to websites for your clients", though.

> everybody else used CRLF pair to indicate a linebreak

Almost everybody... https://en.wikipedia.org/wiki/Newline#Representation mentions a couple that apparently used LFCR.

jfk13··on Google Chrome pushes browser history-based ad targeting
I believe Firefox blocks them by default. See https://support.mozilla.org/en-US/kb/third-party-cookies-fir...
jfk13··on Russia's Luna-25 spacecraft crashes into moon
Sad that they didn't make the soft landing. Let's hope India's attempt succeeds!

Still, I love the phrasing of the Roscosmos quote:

> "The apparatus moved into an unpredictable orbit and ceased to exist as a result of a collision with the surface of the Moon"

jfk13··on Fastest branchless binary search
On the other hand, assuming it's OK to ignore the special edge cases (or not even thinking of them) can come back to bite you (or your users) when eventually one of them does show up in a situation you didn't anticipate.
jfk13··on What should you know about Svalbard? (2020)
Found a job locally? Where are you going to live? From wikipedia:

> Almost all housing is owned by the various employers and institutions and rented to their employees; there are only a few privately owned houses, most of which are recreational cabins. Because of this, it is difficult to live on Svalbard without working for an established institution.

jfk13··on Sync Gear: How World War I Fighters Avoided Damaging Their Own Propellers
Indeed, some pushers were used early in WW1; e.g. https://en.wikipedia.org/wiki/Royal_Aircraft_Factory_F.E.2

But as you say, the puller turned out to be superior.

jfk13··on The Quite OK Audio Format for Fast, Lossy Compression
HTML+CSS, converted to PDF via the Save As PDF feature in Firefox. (Or the same could be done with other browsers, but this one apparently comes from FF.)
jfk13··on Mozilla finds CPU bug (bad store forwarding) in Samsung Galaxy S20
Irrelevant. Collecting telemetry such as Mozilla does isn't remotely like having remote root access to people's phones.
jfk13··on Mozilla finds CPU bug (bad store forwarding) in Samsung Galaxy S20
It's not remotely feasible to test more than a tiny fraction of the variety of devices, configurations, and sites that a product like Firefox is going to encounter in the real world.

You know perfectly well that's not what they meant.

> Firefox is unusable on Linux. Way too slow.

That may be true for you, but not in general. Perhaps there's something about your system configuration that it doesn't handle well.

jfk13··on Retrieving your browsing history through a CAPTCHA (2022)
Only seems to work in Chrome (not Safari or Firefox).
jfk13··on One can scarcely help clarifying him: on the Brothers Karamazov
Maybe it's just a personal thing; maybe it's partly about the translation you pick. But I remember reading Crime & Punishment back in my 20s (without any expectations or background knowledge), and I found it absolutely gripping.

[eta:] On the other hand, some years later I got totally bogged down in Brothers Karamazov, and (rarely, for me) didn't finish the book.

jfk13··on Is This an Emoji?
A minor correction:

> Let's say we want to display the emoji for a brown man, “<brown man>”. There isn't a code point for that. Instead we use “<man> ZWJ <brown>”.

(with the emoji replaced, as I expect HN would strip them).

That's inaccurate: skin tone modifiers are used directly after a base emoji character, without a zero-width joiner in between.

jfk13··on Got called to a professor’s office after a complaint his SPARC4 was running slow
Ah, good times.... we used to do similar things across the HP Apollo workstations at the place where a friend of mine worked (and I unofficially "borrowed" computing facilities for a project of my own -- though I did also contribute a substantial speed optimization to their main product, so nobody seemed to mind).
jfk13··on I am dying of squamous cell carcinoma, and potential treatments are out of reach
Yes, I suppose it could be taken that way. I wasn't intending to argue one way or the other, merely to point out that such an apparently simple condition ("if someone understands...") actually encompasses a huge amount of uncertainty, and so doesn't necessarily represent the "easy answer" that it might at first appear.
jfk13··on I am dying of squamous cell carcinoma, and potential treatments are out of reach
And how do we assess whether "someone understands the risk"? Often, I suspect nobody really "understands" the risk of some minimally-tested, experimental treatment.
jfk13··on I am dying of squamous cell carcinoma, and potential treatments are out of reach
Well, those are pretty controversial topics, so I'm not sure how much the analogy helps.

jfk13··on Cree Syllabics (2002)
Do you have trouble with "n" vs "u"? How about "b", "d", "p", "q"?
jfk13··on Could an industrial civilization have predated humans on Earth?
Surprised no-one has mentioned Betteridge's Law of Headlines yet.
jfk13··on The Web Assembly Shaper
> Harfbuzz is used in Firefox, Chrome and Safari for example

Not to dispute harfbuzz's significance -- it's a crucial component of much of the software we use every day -- but are you sure about Safari? I thought it relied on Apple's Core Text framework to handle font shaping.
