EliRivers··on What if AI made the world’s economic growth explode?
Sure looks like the wealthy have captured an awful lot:

EliRivers··on AMD CEO sees chips from TSMC's US plant costing 5%-20% more
The US has plenty of manufacturing operations much more complicated than building CPUs

It's my understanding that this is not the case. That CPU (and similar) manufacturing is considered one of the most complex processes humanity has ever developed. What are these plenty of manufacturing operations that are more complicated?

EliRivers··on Hyatt Hotels are using algorithmic Rest “smoking detectors”
"Taken at face value, you couldn't even use a pocket calculator to back up a management decision."

That makes no sense. I am the manager. I make the decision. The calculator gives me some numbers but I am still the manager, still the decision maker, and I can use any tools appropriate to inform my decisions. Even a calculator. Taken at face value, that's what it says. That the calculator doesn't make the management decision; a person does.

EliRivers··on America's largest power grid is struggling to meet demand from AI
If the alternative - that people pay an absolute fortune just to make their own houses liveable - comes out worse, seems like a good option to me. The Great God market isn't magically going to make ordinary people's lives better and the USA, despite appearances to the contrary sometimes, isn't meant to be a Dadaist art project in which everyone dedicates their lives to seeing what happens when you let "the market" do anything it likes.
EliRivers··on America's largest power grid is struggling to meet demand from AI
A nice idea I've seen is that residential households pay a low amount per kilowatt-hour they consume until they reach some determined minimum "amount of energy this household needs to maintain a basic standard of living", and after that residential users go onto market rate.

Anyone using that energy to make a profit - that is, run a business - pays market rate from the start.

EliRivers··on At Least 13 People Died by Suicide Amid U.K. Post Office Scandal, Report Says
Has the mental health of the nation got twice as bad in 2 years? Obviously not.

Assuming that's true, do we know if the new claims are fraudulent, or are they valid claims that people simply didn't claim for before?

EliRivers··on Peter Thiel: Elon Musk has given up on Mars
Genuine question; what even would make going to Mars economically viable? It we mean by economically viable something like "when the amount of wealth we generate, where wealth is stuff that makes the lives of humans better, exceeds that which we expended to do it" there's not a lot that springs to mind that would make going to Mars an economic proposition.
EliRivers··on ARIA, the UK's Bet to Build Scientific Revolutions
If we're chucking in on these, which seems to be the case, also Black Arrow; the UK's nascent space programme which in 1971 put a satellite into orbit (which is small beans now but in 1971 was still a serious achievement) and was then cancelled because the US said they'd give the UK discount pricing on their own launches, and then when it was cancelled the US said "Ha! Suckers! Of course you're not getting a discount!" (accounts of this may vary)

I think the UK might be the only country that developed, and then fully abandoned, its own capability to launch satellites. Now being slowly recreated, fifty years later.

EliRivers··on We Saw Medicaid Work Requirements Up Close. You Don't Want This Chaos
I expect someone will just hand a huge amount of money to some AI snake oil company who will fuck it mightily on their behalf in a "nobody could have seen this coming, we're not at fault" manner.
EliRivers··on The Rise of the Japanese Toilet
"most bidets starts leaking after 6-12 months."

Well that just doesn't sound true at all. I would definitely remember if it leaked every year. Do you have any evidence for this? A bidet is pretty basic plumbing, and basic plumbing can go decades without leaking.

I guess if someone goes out and buys cheap parts that fail fast, and always does that, then you'll get some people whose plumbing fails every six months and everyone else goes years or decades without problems.

EliRivers··on C++ to Rust Phrasebook
To be fair, there's a reason for the pattern with init methods you're describing.

Without prejudice on any other reasons, the most common reason for this pattern I've seen is people thinking in languages that basically don't have constructors, yet writing C++. It's not a good reason.

EliRivers··on C++ to Rust Phrasebook
One of the common pitfalls I've seen in my time is someone writing a language they are familiar with in a language that just doesn't fit; trying to apply idioms that flow well with one language to another language where that's just not a good way to achieve the same ends.

An example I've seen a lot is a C thinker writing C++ classes with an init() function; sure, it works, but the C++ way is to do that in constructors. (All those about to start listing exceptions to that C++ idiom, please save it to the end, thanks!) The C thinker is still thinking about objects as "allocate memory, then set values" rather than the C++ way where allocation and initialisation are wrapped together into a single action (from the programmer's point of view).

So what are these pitfalls for a C++ thinker when writing Rust? This "phrasebook" is embracing the idea of taking a C++ way of thinking and applying it to Rust, which I'm sure will be fine for many situations, but what are the C++ phrases that are just the wrong way to do things in Rust?

EliRivers··on Denmark to raise retirement age to 70
Maybe the system needs a rethink; an expectation that everyone able to will pretty much work their whole lives, but making work much less miserable and time-consuming so that's just fine.

Ha. Total pipedream. It is easier to imagine the end of the world than to imagine the end of our current economic system.

EliRivers··on C++26: more constexpr in the standard library
Sounds like you should use those other languages. Right tool for the right job.
EliRivers··on Less Slow C++
If you're taking priority requests:

"How coding FPGA differs from GPU and what is High-Level Synthesis, Verilog, and VHDL? #36" Yes please!

EliRivers··on AGI Is Still 30 Years Away – Ege Erdil and Tamay Besiroglu
Would AGI be recognisable to us? When a human pushes over an anthill, what do the ants think happened? Do they even know the anthill is gone; did they have concept of the anthill as a huge edifice, or did they only know earth to squeeze through and some biological instinct.

If general intelligence arrived and did whatever general intelligence would do, would we even see it? Or would there just be things that happened that we just can't comprehend?

EliRivers··on AGI Is Still 30 Years Away – Ege Erdil and Tamay Besiroglu
Yes, we do seem to have a very high opinion of ourselves.
EliRivers··on AGI Is Still 30 Years Away – Ege Erdil and Tamay Besiroglu
I'd expect it to be generalised, where we (and everything else we've ever met) are specialised. Our intelligence is shaped by our biology and our environment; the limitations on our thinking are themselves concepts the best of us can barely glimpse. Some kind of intelligence that inherently transcends its substrate.

What that would look like, how it would think, the kind of mental considerations it would have, I do not know. I do suspect that declaring something that thinks like us would have "general intelligence" to be a symptom of our limited thinking.

EliRivers··on AGI Is Still 30 Years Away – Ege Erdil and Tamay Besiroglu
A bit poorly named; not really very general. AHI would be a better name.
EliRivers··on AGI Is Still 30 Years Away – Ege Erdil and Tamay Besiroglu
I'd accept that as a human kind of intelligence, but I'm really hoping that AGI would be a bit more general. That clever human thinking would be a subset of what it could do.
EliRivers··on AGI Is Still 30 Years Away – Ege Erdil and Tamay Besiroglu
Would we even recognise it if it arrived? We'd recognise human level intelligence, probably, but that's specialised. What would general intelligence even look like.
EliRivers··on Trump exempts phones, computers, chips from ‘reciprocal’ tariffs
provided they continue to go through with the investment

I recall the Foxconn Wisconsin situation, and I have no doubt Apple et al are well aware of it. String out a pretense of building factories in the US for the next three and a half years? Easy peasy. President Trump will soon get bored of this game anyway and move on to the next one; he already looks like he's bored of it and it didn't bring him universal acclaim and admiration.

EliRivers··on The End of Sierra as We Knew It, Part 1: The Acquisition
People say they want realism in games. They don't. That's just a thing people have learned to say.

EliRivers··on Utah becomes first US state to ban fluoride in its water
Indeed. While the UK and the USA have comparable levels of dental health, in US television actors typically require very good (or rather, cosmetically appealing according to local norms) teeth in order to succeed. In the UK, it's less important.
EliRivers··on Percentage of parents financially supporting adult children reaches 3-year high
Genuine question that may come across as snark, but I promise it's not!

"you don't grow up until you have to balance a check book."

Is that just shorthand for "be properly aware your own budget and finances" or are there literally still enough people using check (cheque as I might write) books in the US that this is still a literal task people learn.

EliRivers··on How much are LLMs boosting real-world programmer productivity?
Every so often, it saves me a few hours on a task that's not very difficult, but that I just don't know how to do already. Generally something generic a lot of people have already done.

An example from today was using XAudio2 on windows to output sound, where that sound was already being fetched as interleaved data from a network source. I could have read the docs, found some example code, and bashed it together in a few hours; but I asked one of the LLMs and it gave me some example code tuned to my request, giving me a head start on that.

I had to already know a lot of context to be able to ask it the right questions, I suspect, and to thence tune it with a few follow up questions.

EliRivers··on Jeff Bezos exerts more control of Washington Post opinion
Free from anything that stops him extracting all surplus value from consumers and suppliers both.
EliRivers··on Jeff Bezos exerts more control of Washington Post opinion
Seeing Bezos advocate for free markers is a massive dissonance, until I remind myself that he hasn't said what they should be free of. Bezos would like to be free to run competition out of town, force brutal terms on suppliers, all that sort of thing.
EliRivers··on No Bitcoin ETFs at Vanguard (2024)
Indeed. Other commodities have other strengths; oil can be turned into a huge range of products that make people's lives better, wheat can be literally used to make food to radically enhance people's lived experience, aluminium is a key component in an enormous range of goods covering almost every aspect of life. If what Bitcoin can offer isn't having any actual application that improves anyone's life but is easy to move around, well, gotta go with your only strength, I guess.
EliRivers··on No Bitcoin ETFs at Vanguard (2024)
Other commodities have a physical existence. That's quite a big difference.
