I don't understand these comments, both the product and the website is fantastic. This is the most impressive solo project I've seen in my life. I'm especially intrigued by the novel grinder design; and it is amazing that you could fit the motor in there. Top notch industrial design coupled with novel approaches. Almost in too-good-to-be-true land, but I will take your claims at face value. If this all checks out, this is an amazing set of products for the enthusiasts at home at a good price point (considering the market).

And don't get discouraged by the attacks on your web design, I think the website is excellent the way it is. Leave it to some reviewers to go into nitty gritty real world stuff; your website does a great job of showcasing the design language and what's great about the product.
This reminds me of when I was trying to do Minecraft style chunking in Bevy. I was in a situation where (instead of doing the not-so-obvious fix) I threw parallelization, compiler optimization, caching, release flags etc. at my project and nothing made it go faster. I could not figure out why it was so slow. Turns out what I was doing was so unoptimized that I might've as well loaded the whole world per frame.

You live and you learn :)

So "devops" existed even in the mainframe era! :-D
Everyone has, even the hardware vendors are treating these rules as the golden standard to which they can optimize and conform. So it's too late. But it's still a shame.

The acquire/release semantics make perfect sense for locks, because that's what it was designed for. Designing anything else with them is extremely difficult, and in practice such work tends to lean heavily on the full-barrier "sequentially consistent" primitive instead. The older read/write barrier instructions were much simpler. (And x86 is simpler still, with just one reordering rule to worry about and a single idea of serializing instructions to regulate it).

I understand if the window were taller, I'd have seen the actual price cards. I think it's just that when you click "Pricing", you expect the next obvious number you see to be the price.
The use of "we" and the phrase "our institutions" begs the question somewhat, because people don't necessarily perceive public institutions to be theirs or acting in their interests. Someone who doesn't trust an institution likely feels that way because it doesn't appear to be "our institution" in the first place; it looks like somebody else's institution, doing what it likes according to the logic of those other people who it actually serves.

Nor do people who mistrust institutions necessarily feel a sense of identity with any group who could meaningfully be said to exercise control over them; so who's the "we" who need to be rebuilding anything?
Thank you so much for the order!

I think the trouble with using fluid-o-tech style pumps (I actually started out by buying one) is that they're really optimized for machines where the space, cost, and weight of the pump aren't a significant concern, so they can get away with using a giant slow AC motor with big gears. That sort of motor unfortunately doesn't scale down too well, so instead we use a small DC brushless motor and spin it very fast, and then even with the power supply it still ends up being a smaller and cheaper setup.

> Gboard's implementation is super annoying for me because it keeps trying to skip over word boundaries, and it's quite difficult to move just one or two characters over, because it waits for you to swipe far enough before activating any movement. Just awful.

This is interesting—Gboard also by default uses a long-press on the space bar to change keyboards, so I often find myself triggering that while meaning to scroll (or, more often, meaning to long press 'n' for '!'), but, as long as I'm quick enough, I've never observed it to be hesitant about moving one or two characters.

For perhaps the first time in history, the world knew before being told: if you'd seen the sky, you had the scoop. The usual arbiters of newsworthiness, stripped of their accustomed role in filtering reality, had to be content with merely labeling it. It took them ninety minutes to agree on Fireflies. A half hour after that, the first Fourier transforms appeared in the noosphere; to no one's great surprise, the Fireflies had not wasted their dying breaths on static. There was pattern embedded in that terminal chorus, some cryptic intelligence that resisted all earthly analysis. The experts, rigorously empirical, refused to speculate: they only admitted that the Fireflies had said something. They didn't know what.

Everyone else did. How else would you explain 65,536 probes evenly dispersed along a lat-long grid that barely left any square meter of planetary surface unexposed? Obviously the Flies had taken our picture. The whole world had been caught with its pants down in panoramic composite freeze-frame. We'd been surveyed—whether as a prelude to formal introductions or outright invasion was anyone's guess.
Yeah, this. Anyone who criticizes this project is simply revealing their ignorance of what it takes to build a product like this. Super-impressive. And the web-site looks top-notch too (though there is some constructive criticism in other threads that would improve it). Hard to believe this was a solo project.
Kind of curious that this is happening in NZ, the tourism beneficiary of literary and artistic (and yes, technical) largesse...

"The annual tourist influx to New Zealand grew 40%, from 1.7 million in 2000 to 2.4 million in 2006, has been attributed in large part to The Lord of the Rings phenomenon. 6% of international visitors cited the film as a reason for traveling to the country."

Yeah, I have a Chromebook where the process to switch to coreboot was basically unscrew a write-protect screw (AIUI newer models might not even need that) and then you just run an installer script. That's a (...kinda) different particular firmware, but the process works. It just depends on your hardware.
Caves of Qud, similar to Dwarf Fortress, is one of those games that I have a lot of respect for. The amount of complexity and content is pretty nuts.

How did you find this kind of team? I know you note B2B/unicorns can have these, but I have never found them myself. I find it difficult: Reach out to the CPO/CEO with something innovative or genuine passion for the industry area, and they either get you in excited and others in the C/tech suite are against you / already busy with projects, OR they see you as a threat and just talk to learn.

I am also wary because I have seen such teams before (e.g. a HTML5 team, yes silly as it sounds, web sockets and SVG felt like they opened entire new ways of making games), and a data science team using BERT etc (outdated totally by ChatGPT and made useless). Likewise I lead a team to adapt React (before it was predominant) which helped, and I was liked on the team by most for helping them code with less bugs (some of the old guard did not like using React). However, once that happened, it was done. My managers were changed, for someone who loved making lots of plans. I then got over-managed to the point I changed my career as it was obvious this manager had no interest in any future risks in the next 3-5 years of their time in that seat.

I just don't see stories where these teams somehow make a 2nd product for the company which actually successfully scales. They usually get eaten by being overtaken technically, or eaten by the main product. So what do you do after the "eaten" point? Does the company keep your around?
How do you deal with putting information in your error messages?

My understanding is that Zig errors can't contain any data. But an error message like "file not found" is awful. Are your error messages awful, or is there some way to get information into them so that you can say "file 'foo/bar.json' not found"?
The website is good for someone who is not primarily a web designer. It can serve as a starting point which can be polished into something quite nice.
> At the limit limit, there is no difference between Result<T,E> and checked exceptions

How do you figure? A Result<T,E> always means a branch after function calls, while checked exceptions have no such cost.

Toy example: https://godbolt.org/z/Gqo9n17c6

It's trivially observed that exceptions simply have less code in the normal path. There's no post-call checking for errors, which is of course present in the Result<T,E> approach. And even where the exception is caught, that's not part of the "hot loop". It's not executed at all normally. Unwinding exceptions are completely free when they don't happen. The same is simply not true and never can be true of a return-value based propagation.
It's not that myopic though is it? Over the last 2 or so years breakthroughs in AI have given us access to a new level of technology. It's a rich seam to mine, so society is likely to benefit more from a state focussing its research on it instead of e.g. understanding Maori migration a few hundred years ago. A stronger economy leads to more funding for public services to support people alive today.

> if you expect your employees to produce every week only what they can do in an afternoon and no more

... then they will have time to fix problems that arrive randomly, rework the parts of their work they got wrong on the first try, and study and train to stay sharp to do the next piece of work. Ironically, all of those will make them produce their next piece of work faster, making this one "problem" worse and worse.

But I left the real benefit to the end... those people will have enough time to think about how they can work into improving something on their workplace. You know, the people that actually do the work, how they can apply the work they know about, because they do it, instead of people that know nothing about it being specialized in thinking how to apply other people's work.

The GP saw a good manager trying to keep his people safe from a dysfunctional organization. The dysfunctional organization is a read flag, for sure, but it doesn't automatically mean the environment is a bad one.

Only to wake up hours later and say, it is working and they both struggled to milk the bag to increase the flow, they talked for 20 minutes while they both tried to "fix it" and he finally went back to sleep for the last time.

Underappreciated reality.

Because customer-insurer relationships are the only side of the healthcare system that most people see, they're oblivious to what are actually pass-through insurer-provider issues.

As you said, the reality is that insurers operate with pretty reasonable margins and incredibly meager per-claim overhead costs. They're stuck trying to make 2 + 1 = 2.

If the finger should be pointed at root causes in the US health system, it should be at:

- Providers overbilling (particular in certain specialties)

- Medical schools, for charging too much and under-expanding capacity

- The federal government/Congress, for failing to expand residency funding to increase supply (especially in generalist provider categories)
What this tells me is that industries with limited growth potential and who are focused on incremental rather than transformative technology do not respond to government carrots, and to the extent that they do anything, it is to arrange scenarios where they privatize the carrots and socialize the costs.

There is no return on investment for investments in rural fiber. Infrastructure needs a high density of users to be profitable.

If we really think that the speed and reliability of fiber service is important for rural users, we should directly subsidize it - like we do for Amtrak in the Great Plains states - and stop pretending like we care by paying off the corporations and their shareholders.
The insurance companies don't have medical training either. I know far, far more about my body's medical situation than them.

Doctors and medical research may supply me with additional medical knowledge, but the insurance company can go to hell. They don't know a damn thing about any of this.
Again, I'm no expert here but find this stuff fascinating. Could the simplicity possibly allow some radically different CPU design that makes the lookups alone nearly instantaneous? I could imagine some types of optical/photonic physical 3D hash table structures - even ones where the same physical structure could support a large number of read operations in parallel if pre-arranged by a compiler to not physically interfere. I imagine a cpu with only one instruction could be physically miniscule, and therefore pack a lot of cores in a small space.

Hypothetically, if it were orders of magnitude faster than a normal CPU, one could still perform rapid computation on larger numbers as needed while keeping the cpu physically 8 bit- yet be able to revert to even higher performance when less precision is needed.
Generally warming up caches (l1i, l1d, l2, ...) and other hardware state (e.g. out-of-order engine) so that you get a better picture of how your program will run in the steady state, rather than how it will perform on the first iteration with 'cold caches'. The justification for this is that in most (but not all) software applications, you should expect a reasonable amount of spatial/temporal locality and thus for your caches to be useful. So the 'average' performance of your program would be best captured by how the program runs when 'warm'.

Warm -> populated with the code/data your program uses. Cold -> empty, or filled with stuff your program doesn't use.

I do think that the case of exception handling is one where I would question the validity of this approach: if you catch exceptions rarely, it's quite reasonable to expect that the relevant lines would have been conflict'ed out of your l1i at some point in the interim, and therefore that the l1i (or even l2!) fetch cost is reasonable to include in the benchmark. However, if you expect your exceptions to fire 'relatively often' then it again becomes reasonable to warm up the caches before measuring, so it really comes down to the characteristics of your workload.

Same here, just had one in the US and I refused to be sedated as I knew from previous one in EU that it is tolerable. You should have seen the song and dance of the provider trying to convince me to get sedated. In the end they accepted my decision. Afterwards about everybody in the clinic came to see me as if I was a hero of sorts. However,the whole episode gave me a good insight as to why US healthcare is so expensive.

They do have a cost to program size, yes, but they have ~zero impact on performance when never used. They are completely cold, outside of normal flow.
What you are describing are series hybrids where the power source generate electricity and the wheels are driven from the electric motor.

Nissan sells this as their E-Power system Hybrid. The Chevy Volt plug-in hybrids were primarily series hybrids when in hybrid mode.

Running the gas engine to charge the battery and drive the wheels is not as efficient as just using a large EV battery but the trade offs in cost, weight, and range may make it worthwhile for now.

I'm not sure I understand this comment. C++ is one of the very few languages that can be used for programming everything from a web server to a garbage collector to firmware. There's no "raising" going on here.
> What exactly are you saying this is an example of?

A prominent conjecture in number theory, taken quite seriously for centuries, but which was quickly and rather easily disproven once computers became powerful enough.

No, it is not a exact analogy for Fermat, nor BSD, nor Riemann, nor ...

My initial point of interest was u/bootby's comment - why the heck would a room full of experts (presumably noteworthy math professors) become so angry at some grad student's comment? Then /usr/baruz's comment, about things which "seem proven and make intuitive sense, but needed formal buttressing". On occasion, "seemed" and "intuition" prove to be wrong, and Euler was a pretty-good example that.

You're looking at the world as a poor person. If you had Elon's brilliance you'd probably quit after you made $5 million dollars or so and definitely after you sold Zip2 back in the 1990s and spent the rest of your life on the beach. The only reason he's still working as hard as he does is not because he wants to spend that on himself. He wants the glory of going to Mars and having a positive impact on humanity and that requires control of the activities of large companies like SpaceX, etc. which requires ownership stakes in those companies that are valued in the billions.

One of the reasons that he campaigned so hard for Trump is that Kamala's proposed wealth taxes on unrealized capital gains were going to take his companies from him and he'd have to sell to Vanguard or Blackrock, who would give control of the companies to Boeing-tier mediocrity which would mean that we'd never get to Mars. There have been so many companies where the founders sold out and retired because they had enough money and they got bought by big conglomerates who destroyed those companies with mediocre management and neglect. This is the great thing about Elon, he just keeps building and leveraging all that money to create bigger and bigger companies using his creativity and management ability to achieve his goal of launching an era of space exploration.

They claim that they are the same project that was initiated by Matthias Ettrich in 1996.

They also kinda imply that they would use the KDE name, if they were allowed to, but someone else owns the rights for it. ("Why don't you do this very natural thing?" "I am not allowed to.")

They indeed don't claim or imply that the KDE Foundation is an "imposter". They also don't say anything about whether the KDE Foundation is also a continuation of the same project.
To clarify, the point of it isn't _just_ performance.

It's a combination for writing the iteration code in a functional style, which some people like/prefer, while retaining certain performance characteristics that you'd get from writing more imperative code.

For example, the "naive" approach to functional programming + concurrency results in some unintentional bottlenecks (see the concurrent iteration example on the home page).
