I thought the whole point of roast curves is that the beans are the exogenous variable, even the same beans at different times of the day. And that those changes influence the outcomes (bean temp) even if it's nearly imperceptible.

I've never paid attention to the minute differences, but if you're the kind of roaster who believes in the art of it versus the science, I think it'd be cool to try to map this model to certain outcomes - eg more or less fruity, chocolate, etc. Or actually throw in stuff like humidity, bean age, time of day, etc.

I've done a few hundred roasts, but by hand cranking a flour sifter over a heat gun. My model inputs are noise, smell, appearance. I've never been interested in pursuing a roast curve or profile, because I'm a barbarian.

For the same thrust it's more efficient to accelerate a large mass of air a small amount than t accelerate a small mass of air a large amount. The fan is what gives you that.

I rough guessed the cost of fuel over a 737's life as $150 million. Where the engines cost something around $30 million. That pushes the engineering economics towards maximizing the engines efficiency.

I'm suspicious that bypass ratio's for turbofans are close to maxed out. The diameter of the fan gets unwieldy. That was the design issue that the 737 Max was trying to get around. With bad results. Possible the future is hybrid designs with two engines and 4 or more electrically driven fans.

>> Do people want to live in a world where they can't trust anything they didn't personally see with their own eyes?

Maybe it will all turn out for the better, in an unexpected way. Before the advent of the Internet and then the flood of cheap "content", there were newspapers and TV news. These had real professionals behind them and some level of integrity and proofcheck of the facts, so at least for reputable names, you could reasonably trust what you saw presented by them.

When the garbage content will completely take over the real landscape, like litter in India let's say, we'll be left with no choice but to turn back to the old news channels: real journalism. And I think it's almost inevitable as there's no stopping to the littering people. Funnily, much of this content originates in the litter-filled Asian countries, where the promise of a few bucks made on the "content platforms" attracts huge crowds with no scruples whatsoever and if AI attracts views and likes, let's drown them in AI.

I personally have a visceral feeling of hate when I'm tricked by some video being AI and by reading comments, I'm far from alone.

Even in the earliest stages of the DDN concept, we had already decided to pass features down to the next layer.

I never even ran an ablation that disabled the stem features; I assume the network would still train without them, but since the previous layer has already computed the features, it would be wasteful not to reuse them. Retaining the stem features also lets DDN adopt the more efficient single-shot-generator architecture.

Another deeper reason is that, unlike diffusion models, DDN does not need the Markov-chain property between adjacent layers.

data-animate - Animates element attributes over time. data-on-resize - Runs an expression on element resize. data-scroll-into-view - Scrolls an element into view.

If these are footguns then they can't be designed very well. I also don't think you can say that they'd only appeal to a small group.

I don't have any problem with them charging for whatever they want to. But let's not make up excuses.

Gigabit ethernet "requires" 4 pairs of no-less-than cat5. The 100mbps standard that won the race -- 100BASE-TX -- also "requires" no-less-than cat5, but only 2 pairs of it.

Either may "work" with cat3, but that's by no means a certainty. The twists are simply not very twisty with cat3 compared to any of its successors...and this does make a difference.

But at least: If gigabit is flaky over a given span of whatever wire, then the connection can be forced to be not-gigabit by eliminating the brown and blue pairs. Neither end will get stuck trying to make a 1000BASE-T connection with only the orange and green pairs being contiguous.

I think I even still have a couple of factory-made cat5-ish patch cords kicking around that feature only 2 pairs; the grey patch cord that came with the OG Xbox is one such contrivance. Putting one of these in at either end brings the link down to no more than 100BASE-TX without any additional work.

(Scare quotes intentional, but it may be worth trying if the wire is already there.

Disclaimers: I've made many thousands of terminations of cat3 -- it's nice and fast to work with using things like 66 blocks. I've also spent waaaaay too much time trying to troubleshoot Ethernet networks that had been made with in-situ wiring that wasn't quite cutting the mustard.)

In safety-critical systems, we distinguish between accidents (actual loss, e.g. lives, equipment, etc.) and hazardous states. The equation is

hazardous state + environmental conditions = accident

Since we can only control the system, and not its environment, we focus on preventing hazardous states, rather than accidents. If we can keep the system out of all hazardous states, we also avoid accidents. (Trying to prevent accidents while not paying attention to hazardous states amounts to relying on the environment always being on our side, and is bound to fail eventually.)

One such hazardous state we have defined in aviation is "less than N minutes of fuel remaining when landing". If an aircraft lands with less than N minutes of fuel on board, it would only have taken bad environmental conditions to make it crash, rather than land. Thus we design commercial aviation so that planes always have N minutes of fuel remaining when landing. If they don't, that's a big deal: they've entered a hazardous state, and we never want to see that. (I don't remember if N is 30 or 45 or 60 but somewhere in that region.)

For another example, one of my children loves playing around cliffs and rocks. Initially he was very keen on promising me that he wouldn't fall down. I explained the difference between accidents and hazardous states to him in childrens' terms, and he realised slowly that he cannot control whether or not he has an accident, so it's a bad idea to promise me that he won't have an accident. What he can control is whether or not bad environmental conditions lead to an accident, and he does that by keeping out of hazardous states. In this case, the hazardous state would be standing less than a child-height within a ledge when there is nobody below ready to catch. He can promise me to avoid that, and that satisfies me a lot more than a promise to not fall.

I defined it as open (core) source. Because that's what it is. Or source available. Both terms are precise.

But what I explained is that contrary to many open core projects, n8n public sources form a (generous) comprehensive solution, aside a couple of features that should have been public sources, the solution stands as a grea, with little to no limits, platform. Unlimited users, no cap on workflows, no cap on number of nodes etc etc.

Also, their licensing is good, you can pay and get the extra features and do what you want, including modifications if I'm not mistaken. That's free software without the free beer aspect, I never claimed it was free software or pure open source.

I'm also all for free software, but this is the sort of solution that doesn't fit well with the open source philosophy , making it rare to see open sourced. That's all.

Now that they raised significant money, the situation will slowly change to prioritize monetization, I guess.

I think the article misses a big reason why they won’t go away, and that is people don’t know what they don’t know.

Technology Connections on YouTube is a great example of this. I was never going to ask AI about the in-depth details about dishwashers, but I’ve watched two 45 minute long videos on the topic and found them fascination. I thought toasters were toasters, until he showed one with a thermostat that blew my mind, and I wish had a modern successor. I never would have found this with AI, as I never would have thought to ask.

The 99% Invisible podcast is another example of this kind of thing.

Countless blogs do the same kind of thing for the readers.

AI limits people do the things they think to ask about. They don’t inspire new ideas on topics previously unknown.

Our definition of 'bad weather' is definitely changing as we gather more data.

Besides regular weather (which airliners aim to avoid except during take off and landing) there are many other factors at play here. There are several almanacs that are used for fuel calculations & navigation, they are updated annually.

The fastest jet stream (the aviation equivalent of the trade winds) recorded is north of 400 Kph, having that with you, against you or perpendicular to your flight path will have a substantial influence on fuel consumption and flight duration.

I agree with you that it may well end up with a regulatory change but that's one of many possible outcomes here. I will definitely keep an eye out for the report on this flight's investigation. It is going to make for very educational reading.

I really like the idea. I also grew up in a household with tons of physical media to explore. I still have my blue ray collection but it’s mainly sitting in the shelf because I honestly don’t know what else to put there.

But I’m wondering reading all the comments from people doing something similar with alternative products etc how they do this legally? I mean I can’t just download stuff from Apple Music and play it offline on some random player. Same with most other streaming providers. Or are you accepting the greyzone here by saying you pay for the service so it doesn’t matter? Or are you happily buying all the content on some other medium / drm free stores to put them on these alternatives players? I specifically mean solutions where one needs some form of copy of the files.

It actually was beginning to work. Corners of the internet where people discuss clothing and fashion trends were starting to buzz about JC Penny randomly starting to have trendier higher quality stuff for reasonable prices, etc.

I think they would've needed a another year or two of runway though to turn the ship around and court an entirely new (non-overlapping) customer base, and the investors simply weren't willing to give them that much time.

On iPhone 12 mini, the battery life is incredibly worse. I was charging once a day, 30 → 70% usually, and now I’m charging all the time I have a chance. I’m not very active user, but each session of screen time reduces the battery significantly. Before that I felt that despite the small battery, the device works forever. Now, I’m back into my iPhone 4S times, when I upgraded to iOS 7.

This is hitting people who aren't tech-savvy particularly hard

I don't really see it among family and friends. My parents who are not very technical mostly went shrug, it looks a bit different and went on with their lives. The only family member who said anything about it was our daughter, who likes it a lot.

Agree that Photos is much-improved.

Personally I am not really a fan of liquid glass. On the Mac, I don't notice it much. On the iPhone I find it more noticeable, the primary thing I'm annoyed by is the overlay with video play controls (macOS too). I would rather have seen them invest time into fixing existing issues than a redesign (e.g. why can I not configure Headphone Accommodations on the Mac for AirPods Max, but I can on the iPhone).

I don't think this is entirely true. I'd bet if you asked people the complexity of quiskort, they'd be more likely to remember it as O(n log n) than as O(n²), even though the first one is average case complexity and the second is worse case. Similarly, if you ask about hashtables or hash maps, you're more likely to hear O(1) than O(n), despite O(n) being the worse case complexity (when all items happen to have the same hash).

Instead, what I think happens is that people tend to talk about the average case complexity of well known algorithms, except that for most algorithms that's the same as worse case, so they tend to forget the distinction. And, if they're evaluating the complexity of something they wrote, they'll probably do the worse case analysis, since that's easier than the average case.

Only one paragraph was about the Middle East, where "Western" morality is on full display, mostly to show that there is no one true goodness anywhere.

You seem to be using a definition of morality that's a lot narrower than what we generally call moral and morality: https://www.oxfordlearnersdictionaries.com/definition/englis...

I don't think your examples show morality at work, but I already realised we disagree on this topic, and I am sure you'll interpret the dictionary definitions differently too.

Thanks for the discourse and enjoy the day.

I think that HackerNews is full of old techie greybeards, whereas Liquid Glass is designed for Gen Z and Gen Alpha. Young people tend to like things that wiggle and bounce around and so on. If I were Apple then I'd say hmm, we still want to be around 20 years from now. So let's design for young people.

> The word Mayday is not required to declare an emergency.

That may be so in the US.

But it is a bad habit to pick up.

Especially if you are an airline pilot and you frequently fly to destinations where English is not the first language.

Or indeed in US airspace where you frequently get international carriers flying in and out.

There is a reason why there is internationally agreed standard phraseology for radio communications.

Everyone learns MAYDAY/PAN and the associated expectations around it (e.g. radio silence etc. etc.)

Not everybody will be able to adequately follow along if you have a long drawn-out waffle discussion over the radio ... "we have a little problem" ... "do you want to declare?" ... "oh wait, standby ...." ...."oh, we're ok for now" ... "oh actually maybe this or that"... yada yada yada.

If its truly an emergency then cut the crap and use the standard phraseology and keep the communications terse.

No external compass, something the group views as (or probably unavoidably knows to be) dangerous. Overcoming the fear of it and then belittling those who haven't completed the same process. Psychologists call that the normalization of deviance. A commercial airline pilot has the external compass in your questionable aviation example.

You don't want a group with initial success with the left, right left and so much enjoyment from the sense of fulfillment in social deviance process that they think they can take over everything.

At best (worst?) I would say it will be a contributing factor to the speed and range of fall dependent on the leverage and the linkage.

The fundamental here is going to be overinflated expectations. I am by inclination a believer in the longterm 7% rate of profit, it's historically sustained, and if people are seeing double or triple this in tech stocks and orders of magnitude higher in crypto and derived products i don't personally see that as indicating a change, as much as showcasing the over valuation in the markets.

Value is about humans. Not leveraged derived products. If there's a big enough collapse in purchasing power or a other covid scale economic collapse, people's inability to buy things for both supply side and cost side reasons is going to be bad.

The reduction in Listed Property Asset value has to come too. That, and a massive correction in the cost of housing for most of the developed world outside the USA. Australia property to income ratios are insanely bad.

At some point, we'll be off an addiction to fossil fuels and a lot of established capital will suffer. The middle east is diversifying their way out. Russia isn't and nor is Trumpist America. China is. The future belongs to China in many ways. China and India, and the growth of Middle classes in Africa.

My conspiracy theory is there is something inherently rotten at Apple and it is simply not possible to build a smartwatch that never mind can match the feature set of the apple watch but also the levels of battery efficiency on the iPhone paired with a smartwatch different than the Apple Watch. I don't know this for a fact but I am sure multiple cheap ish Chinese watch vendors would not choose to intentionally drain the iPhone battery if they could avoid it.

You end up with a weird phenomenon.

Games written for the PlayStation exclusively get to take advantage of everything, but there is nothing to compare the release to.

Alternatively, if a game is release cross-platform, there’s little incentive to tune the performance past the benchmarks of comparable platforms. Why make the PlayStation game look better than Xbox if it involves rewriting engine layer stuff to take advantage of the hardware, for one platform only.

Basically all of the most interesting utilization of the hardware comes at the very end of the consoles lifecycle. It’s been like that for decades.

> Not clear that this would speed things up much today.

It would likely slow things down, actually.

One advantage that a stack has is that the stack memory is "hot"--it is very likely in cache due to the fact that it is all right next to one another and used over and over and over. Statically allocated memory, by contrast, has no such guarantee and every function call is likely to be "cold" and need to pull in the cache line with its static variables.

I built https://dailyalbum.art/ to solve a part of the browsing problem you're talking about. Nothing physical I'm afraid, but I do really love this RFID tap to play idea!

I've curated a list of 500+ critically acclaimed albums, which I continue to add to as the Mercury Prize nominees are announced each year, Rough Trade releases its albums of the year, etc.

It picks 12 a day and that's that; it's the same 12 for everyone. If you see something familiar, you might want to go for that. Or if you're in the mood for something new & different, you can give something unknown a try.

It's been a while since I did abstract algebra, but I'm pretty sure that once you have the additive and multiplicative identities, the rest of the reals can be generated. Which is still a constructive process.

Regardless, the existence of the real numbers is not a matter of need. Their existence is a consequence of how mathematics is defined. Over-simplified, it's a case of if addition and multiplication work, then the real numbers must exist.

Usually, maths doesn't require us to overthink about anything metaphysical. Things either are or they aren't, the problem-solving approach taken to demonstrate a result one way or the other is the fascinating part.

That's the argument authoritarians use when they want to censor something. The problem with it is that it proves too much. Do we also get to apply it to symbols of communism because of the millions of people who died under Mao, or the US flag because of slavery? What about that book Marx wrote that led to all the horrors under the USSR; can't displaying books also be symbolic?

You don't want the government to have the power to decide things like that. It's better that they censor nothing.

It's quite cool honestly, well done to the developer. It works, so it's de facto a good solution.

> The hard parts weren’t the architectural pattern - they were embedded systems constraints. Tuning buffer sizes and designing components shallow enough to fit in 512 bytes required iteration.

I am a bit confused by the choice to use HATEOAS for this. Given the hardware constraints of the controllers I wouldn't have figured that doing handlebars style html templating is a good use of resources, rather than just sending raw data to the client and having it handle the presentation. I probably would have returned a blob of data from the servers and handled everything on the client, but I also am a UI guy first and foremost...

The whole missive from which that comes.[1] This was addressed to the Media Innovation Network conference. (Main topics of the conference: Artificial Intelligence, News in a Post-Truth World, Opportunities for new revenues).

The world needs free, rigorous and objective information. In this context, it is worth remembering Hannah Arendt’s warning that “the ideal subject of totalitarian rule is not the convinced Nazi or the convinced Communist, but people for whom the distinction between fact and fiction and the distinction between true and false no longer exist (The Origins of Totalitarianism, 474).

...

As Pope Francis stressed, “We need courageous entrepreneurs, courageous information engineers, so that the beauty of communication is not corrupted” (Address to Participants in the Jubilee of Communication, 25 January 2025). Communication must be freed from the misguided thinking that corrupts it, from unfair competition and from the degrading practice of so-called clickbait. News agencies are at the frontlines, and are called upon to act in the current communications environment according to principles – unfortunately not always shared – that unite the economic sustainability of the company with the protection of the right to accurate and balanced information.

No need to comment on that.
