IMO the match statement has some very unintuitive behaviour:

match status:
case 404:
return "Not found"

not_found = 404
match status:
case not_found:
return "Not found"

The first checks for equality (`status == 404`) and the second performs an assignment (`not_found = status`).

`not_found` behaving differently from the literal `404` breaks an important principle: “if you see an undocumented constant, you can always name it without changing the code’s meaning” [0].

One could use pumps for increased efficiency during normal operation but the idea is that natural circulation should be able to remove all the heat if the reactor is SCRAMed. NuScale's design for instance only uses pumps for the steam generator, the rest is handled by natural circulation and the reactor sits in a water pool that needs to be replenished after two weeks in case of a major accident.
That seems like a bit of a reach given that the thread is obviously about GCC.

> Ride sharing’s empty promises can be chalked up to corporate PR… I don’t imagine most riders or investors consider those when calling a car or investing.

I disagree. Ridesharing promised sharing a car. That is the whole concept: anyone with a car could pick up passengers and be rewarded by it. See also carpooling.

This is not what Uber or Lyft do, because that business was regulated out of existence by the taxicab lobby. We're talking about an established monopoly which fought any ride hailing service that was presenting any competition to their business.

What Uber and Lyft ended up getting away with was ride hailing services. They got away with it by leveraging existing legislation on vehicle rentals with their own driver. Still, that business is only available to licensed companies, not the regular public.

Getting back to ridesharing, the underlying thesis and the main value proposition of carsharing is that the service provided a way for everyone with a car to monetize their ride by picking up a passenger in exchange for a small fee. Instead of going through your commute with your car empty, you could pick a passenger willing to pay you for your trouble. That would take cars from the street, lessen traffic congestions, and change the way public transportation was used.

I see. It has low precedence in the operator hierarchy [1] so

False or w := 1:

Is grouped like so:

(False or w) := 1

Which is a SyntaxError. That's... not a smart place for it to be in the operator hierarchy. I expected it to be near the very top, like await.

There are two aspects I have been thinking about while looking at this: Introduction of non-obvious behavior (foot-guns) and readability. Readability is important, but I have been thinking primarily about the foot-gun bits, and you have been emphasizing the readability bits. I can't really accurately assess readability of something until I encounter it in the wild.
No, he's right, nuclear is held back by red tape. The energy density of nuclear is so high it beats literally everything. Sans pointless laws or subsidies there is no reason to believe nuclear is less useful than renewables.
I’m really liking the look of this but I’m curious as for what happens if you have more than ten hobbies, for example?
A tangential question that has always bothered me is "How do you get to Alpha Centauri". Or to put it another way, I can probably set off to Alpha Centauri using today's technology. My corpse would arrive there probably in 130,000 years. Give or take an order of magnitude (I've not run the numbers properly). Now I'm extremely confident that the human race in the next 100 years could design a craft that would be able to travel to Alpha Centauri in less than 129,900 years. So. How do I get to alpha centauri?
Just a vaguely interesting question that bothers me.

Or to put it another way, how pissed off would you be when you set off to alpha centuri and you arrive to find your bloody grandson vaping and listening to Lil Nas x.

I've done alright. But capital markets are usually much more sane than internet message boards, so it's not like there is a lot of financial opportunity by saying obvious things, it's only when you meet someone steeped in irreality that telling the truth becomes a radical act.
Your wishy-washy handwaving style of argument is all fine and good for the internet but show me a country (or even a reasonably sized city) that's actually self-sufficient from solar and wind renewables (backed by storage).

Why do you think Germany is signing multi-billion/multi-decade contracts to ship Russian gas if solar/wind+storage is a solved problem?
Yeah that’s a similar example of incompetent security or network engineering. (Or lack thereof)
Nuclear is also by far more dangerous and long-term-problematic than everything else, hence the regulations.

> We have no long term solution for the storage and disposal of enrichment byproducts. There is reprocessing but the results are simply less toxic (eg UF6 -> UF4) and are, to date, expensive

Depleted uranium is a useful and valuable material and not just a “byproduct” to be “disposed” of.

> We have no long term solution on the storage and disposal of fission waste products

Long-lived fission waste products can be fed into breeder reactors to produce new fuel. We don’t do this because we haven’t chosen to grow the deployment of nuclear power. The need for long term storage of long-lived fission waste products is a consequence of self-inflicted decline that the advocates of self-inflicted decline can turn around and use as an argument in favor of self-inflicted decline.
People want a modern and cool tools with bangs and whistles.
They 'have nothing to hide', they trust 'SaaS' as a collective agreement on "advancement' and 'inevitable mandatory future'.

Corporations want data and control over UX. I see this as a happy relationship between owners with knowledge and slaves with lack of survival instinct.

I can accept some form of work related security risk (Hi, Figma) but in general cannot give my intellectual property and businesses processes on any third party. In my company all the process tools are strictly FOSS and under my control.

Personally speaking, tools as Notion cannot hold a candle on my Emacs org-mode workflow. You don't need to reinvent the wheel every 10 years just to feel "cool" and "modern".

Thanks Jerome, I really do appreciate your answer and I know I'm probably not the most fun person to talk to.

I do have a follow-up on this if you'll entertain me: why is it that Facebook stores content of people that it doesn't recognize?

Granted, I'm but a lowly web developer, but it seems like creating business logic that automatically removes content with people that aren't Facebook users would be pretty straightforward to implement. You've already solved the hardest part of that problem, the facial recognition, so why not go all the way?

Moving forward, you'd have a really simple approach to privacy that's transparent and people understand without needing to get into the weeds.

Receiving assurance that I'm not being recognized in photos and videos isn't very comforting when I see Facebook releasing products like the "smart" Ray Bans. Recognizing people in images is only one of many types of data that Facebook gleans from that content, and I don't want anything involving me being processed in any way by that company, whatsoever.

I’m not deeply familiar with other entries in the genre, but ISTR at least one more recent one with more focus on both environmental damage and riders being flung off, though even in that I think the nominal objective was to avoid those outcomes while maximizing ride intensity.

The description would probably be better phrased as an obsession with video game violence than violent video games, though since the article doesn't seem to be blaming the game design for anything, the difference between obsession with a violent mode of play encouraged by the game reward structure and that with a violent mode of play that defies the game reward structure doesn't seem particularly material.
Why do you think pumped storage hydro plants are worse (thank what) ?

They are not ever strictly power plants, rather they provided the much needed buffer to store energy during fluctuating demand and/or supply.

Pumped storage is also completely compatible with both nuclear base load (store extra from base load that can't be easily throttled) and unpredictable renewables sources (store extra when needed, cover - reasonably short - periods of no supply from the source.

@pugio (Interpreting Bonhoeffer) "If you put your fear of God (in other words, some power higher than, and distinctly external to, any social group) you begin to liberate yourself from caring too much about what other people think."

And as such he is making exactly the same mistake, because he is assuming that his God is a higher power, when in fact his God is defined by his community.

Where did he learn what it means to live "The responsible life before God"? From the community he grew up in of course. (My assumption is that God did not appear and teach him in person.)

When stripped of the appeal to the authority of God, his argument becomes "My community values independent thought over group conformity."

I totally agree with him. I just don't find it a solid argument.
It's been 6 years now and IPFS is still stuck with the same problems it had at the start with no real pathway to being useful. Most technology does something useful early on. I don't know the timeline for the web but I don't imagine it involved 6 years of marketing and selling to investors while not serving any purpose well.
If the precedence was higher then you'd get a situation like

x := 1 if cond else 2

never resulting in x := 2 which is pretty unintuitive.

And you have to realize, even if the precedence works out, nobody is going to remember the full ordering for every language they use. People mostly remember a partial order that they're comfortable with, and the rest they either avoid or look up as needed. Like in C++, I couldn't tell you exactly how (a << b = x ? c : d) groups (though I could make an educated guess), and I don't have any interest in remembering it either.

Ultimately, this isn't about the actual precedence. Even if the precedence was magically "right", it's about readability. It's just not readable to assign to a compound expression, even if the language has perfect precedence.

I agree with you, markdown is far better than what you’ve described.

It’s an interesting thing to consider. How do we get somewhere sane between markdown and say HTML for example? What would that look like? Can you get the ease of markdown with something that would let us do more too?
But wouldn't the frame rate be limited by the complexity of the scene, and the available bandwidth? What happens when buffers start to overflow?
I think it's a bit more subtle than that, it's not clear if the answer is wrong, the question is wrong, or both are correct and the universe is wrong (although the story does hint towards one in particular being wrong).
> think people have unrealistic expectations about such a young idea.

This interesting given your description:

> IPFS has the interesting quality that the more popular a piece of content is, the easier it is to get ahold of. If millions of people were using IPFS, the most popular content would be being served by many thousands of people, and finding it and downloading it would be extremely fast.

This idea hasn’t been new since the turn of the century (BitTorrent offered exactly that in 2001) and nothing in that description explains why this is different than the many previous attempts. It’d be interesting to hear about how IPFS plans to maintain that without the problems with abuse and how it keeps competitive performance relative to non-P2P in a world where things like CDNs are much cheaper and easily available than they were around the turn of the century. Using P2P means giving up a lot of control for the content provider and that’s a challenge both from the perspective of the types of content offered and the ability to update or otherwise support it on your schedule.
I think it's possible to find an effort both noble and foolish, which is exactly where I am here. I love that they thought they could shift Microsoft in a better direction, and hoped that they could succeed; but nevertheless was nearly 100% sure that it would never really happen.

I'll point out that the walrus operator was actually accepted while Guido was still BDFL (and the vitriol surrounding the decision to include it led directly to him stepping down from the position [1]), so even accepting the fact that it's a poor addition to the language, does not provide support for the statement that "design by committee" has lead to poor language design decisions.

An interesting dynamic here is that, having read Yeggie's article years back, I regarded Smalltalk as being somewhere towards the conservative end of the axis (at least, in comparison to other dynamic languages.) E.g.: variables declared before use, no truthiness, very few automatic type conversions. It results in a system with a high degree of internal consistency.

And yet, the goal of the language is to enable activity at the liberal end of the axis.

So maybe there's a more subtle goal: you have to enable someone to make a mess, but also equip them to get out of that mess into something more structured, as and when that becomes useful.

As a counter example, spreadsheets are wonderful for making a messy solution to certain kinds of problems - but how do you then it them into a spreadsheet that isn't a mess? I don't know that I've ever seen that happen - it seems like the right means of abstraction and combination to enable that to happen just don't exist in spreadsheet-land.

> He's modelling the system the way he does because it considers a different set of trade-offs.

OK, what are the trade-offs that could possibly warrant going for a set of restrictions that massively impact TCO? For example, in a somewhat related area, one thing that seems plausible is unavailability of a resource: induction motors and generators are less efficient than permanent magnet motors and generators but they avoid supply vulnerability for certain chemical elements, so including them for comparison in a sensitivity analysis is reasonable. But for this situation I don't really see an analogical justification -- or at least I don't see one that would be immediately obvious.

> AFAIK the guys making Electritymap[1] have open-sourced all their data sources[2], maybe it can help.

I don't necessarily mean national grid data -- I have that already. Mostly what I'm missing is transmission data on a sub-national level, and performance and cost estimates of several pumped storage plants that would be binary variables in the model (since each of the proposed sites has different parameters, they're not even integer variables the same way that for example nuclear reactor blocks would be - they have to be a set of binary (built/not-built) options in the solution).
this is pretty clearly an anti-optimization you should report on https://gcc.gnu.org/bugzilla/

IPFS claims to solve this with their name service IPNS which can update to point to a new hash with a revised file. Where the original hash can be cached and used but users can refer to the NS version and get the latest version. But last I saw, the name on IPNS had to be frequently pushed by the original server or it would go away.

We just finished up the Open Source Data Stack conference, which is all about this topic. Feel free to check out the reply.

Specifically, open source approaches to the modern data stack where the trend is picking the right tools for the job that revolve around the warehouse central data store.

"you have to factor in the externalities of the power used to charge them."

Presumably that would be power from nuclear power plants, making electric vehicles that much more carbon free. So the vehicle part could change, and dramatically as electric vehicles replace fossil-fueled vehicles.
Thinking about it, many hydropower schemes are already built as cascades - that could be retrofitted as pumped storage quite easily, if you can interconnect the dams for reasonably cost.
