So, how is it in terms of efficiency? The article mentions that it's 31% more efficient than existing reluctance motors, but doesn't give a comparison to the traditional electric motors.
Very useful. I’ve always thought of Python f-strings as being a language within a language, and not a terribly pythonic one.
I don’t know about “only”, but my observations are that they do.

I’ve volunteered for a youth leadership camp every summer since 1998. Our attendees are 16-18 y/o males exclusively (there’s a female version of the camp but I don’t work there so I have no opinion on that side). Our attendees have been thru a selection process, so I’m not seeing a representative cross section of Ohio, US males of that age. In our sample, though, the number of focused and determined young men is very high.

I’m not at all surprised a 17 y/o would have the drive and determination to keep trying over and over. Not all of them are that way— surely it’s a very small percentage. Nonetheless, that determination isn’t an anomaly in my experience.
Literally every single thing in the post is generalizing a feature that already exists. Don't you think removing these special cases makes the language simpler and easier to use?

You might have a point though in a few releases when GATs are stabilized. I'll keep an eye out for your username complaining about that release ;)
Partially true, but this kind of police overreaction is definitely giving the Alex Jones' of the world ammo. When those characters go on about the thought police of the new world order or whatever, it's not without a little truth.
Hey, thanks for your feedback!

1. This problem could be avoided by leaving the QR code to more than one trusted recipient.

2. When you create the emergency note, you can add up to two personal email addresses. If one doesn’t work, you can rely on your other email server. We also ask the message creators to add our email address to their email provider's safe senders list in order to prevent any notification from us regarding the emergency note from mistakenly ending up in spam.

3. It can be that the server goes down but it will be always restored in less than 24 hours, which means that no emergency note can be mistakenly accessed in the meantime.

Regarding the inactive service from Google: it’s certainly useful in order to let the user decide what to do with the personal data but it doesn’t allow to send a custom message. Moreover, not everyone has a Gmail account.
Also, would be good to see any proper research done on the correlation between kids like that winning prizes and how they fare in the future in terms of driving first-rate innovation wherever they go.

I have a hunch there's hardly any.
It can. But it would likely be too slow and deplete the other nutrients. At that point, you might as well just replace the soil.

Don't try to justify civilian death, strategic bombing was considered even by the RAF and UAAF a war crime in 1942, with some made up thing based in a fantasy understanding of the enemy.
I love my Oasis. Only major issue I have is with leather cover I bought with it.. when cover is open and behind the kindle itself.. you cannot easily grip on it anymore since there's no rised edge anymore. If that's the only thing bothering me, I'm good. The only other is there's no direct O

The more worrying underlying problem is that western governments feel increasingly emboldened to pick and enforce ideologies again- and that's a problem regardless of the ideology. The 20st century is filled with examples of what happens when governments extend beyond their administrative mandates.
> In software we dive into code way to eagerly and way too early in the product process.

Low code doesn't help at all? It's still code.

> Low code allows "less" sunken cost when the inevitable misalignment of requirements happen.

Sunken cost is about investment already incurred that can't be recovered. It's very likely that low code increases software sunk cost problems.

If you use low code as a prototype thing to throw away, that's almost a complete waste of investment.

Wrong low code often is much harder to programmatically test for correctness and debug, so you often need a larger investment to fix it.
What is everyone building in rust, and how do the killer rust features (mentioned in other comments) help you?

I'm not anti rust in any way, it's more of having limited time and so many languages problem. But I'm interested in the types of problems rust is good for, so I could consider it if/when I encounter them
This is typical, and it's a problem that large organizations must work against. I can remember large, complex software development projects having similar fanciful projections (mostly about schedules). Estimates would roll-up from low level managers and would often be completely wrong, accumulating errors as the aggregate estimates moved up the organizational hierarchy.

The only thing saving the individuals responsible for such egregious estimates was "schedule chicken" where each person hoped that someone else would be the first to ask for more time than was scheduled. The first person to do so would be blamed, but everyone else benefited from the extra breathing room in the slipped schedule.
That's NO2, nitrogen dioxide. It contributes to acid rain but not to global warming: https://www.epa.gov/no2-pollution/basic-information-about-no...

Unless you already know this fact it's hard to search for, though. Even with an exact-quotes Google search for "nitrogen dioxide" "global warming potential", Google shows me an info snippet for N2O, nitrous oxide.
Another way to say that would be 'demand is not artificially constrained by expensive gas.' People want trucks, and the price of gas is not making them change their mind. The electric F150 will probably be sold out at MSRP for years

There's no new syntax here?

The first is a new library function that takes a closure as the parameter. This function has existed for as long as Rust has been 1.0 in the crossbeam library, it's just now also in std.

The second change is a new api type.

The third change is a library change to increase flexibility of that library.

The fourth is arguably a bugfix, where existing syntax could not be used in an edge case.

The fifth is unifying the compiler implementations so that some types of patterns now work in code using the oldest compatibility mode that previously only worked in more current modes.

Maybe this is inexperience on my part, but the LCNC tools I've used are very clunky, with UIs that are plain at best, and performance that is cumbersome. While there is certainly a place for them in the business world, I can't see them replacing a really snappy, custom product with beautiful and intuitive UX/UI.
In my experience young minds are far more likely to keep at it where most adults take issue with repetitive processes.

This I definitely agree with, but things are always changing.

There is always new research coming out. Some of the research is bogus, just look at earlier days of smoking, the opiate scandal.

We are constantly adding new factors to the mix, like microplastics. The environment is changing.
Dotfiles being hidden is a UNIXv2 mistake (2012)
I'd just say software is a bit different than hardware. Hardware is quite fixed in time while software is ever changing. XP is really just an iteration of WinNT to unify MS's home and enterprise codebases and XP was really just a point in time snapshot of the code on its way from NT through to 11 today.
> Harvesting methane from landfills sounds like a good idea but is it feasible and scalable in other places?

It is with the right incentive(s), moreover, many landfills in the US are forced to have to install caps that require a substantial investment on the landfill municipality, which simply don't have the funds to do so.

Vespene just closed on a $4 million [0] round, and are set to have a working prototype in CA this year: the business model is actually really elegant use of GHG without the need to install incredibly expensive infrastructure to send the power to the grid and can in turn use the same model that miners who have recaptured the flares from remote Oil and Gas refiners and convert waste CH4 into C02, which is more stable GHG but can also be further recaptured once an auxiliary purpose is found--greenhouse prototypes have been a thing that many miners have experimented with and something like genetic research-grade hemp products could be the solution.

When people on HN complain about how little is being done by tech to offset GHG and subsequent climate change [1] they should really just be looking at themselves and where they work, because as a staunch environmentalist I can't think of a single form of non-research based tech in renewables that has incentivized so many to invest and build recapturing systems via it's economic incentive--be it relocating miners to capture excess hydro in China, to now this.

The model is based on incentives and inducements, which as we've seen in the 13 years is the only viable option, and we're now getting to a matured incentives model (after lots of failures) and as this scales we will reach an inducement model where it is the only sound strategy to offset landfill expenses, reduce damaging release of GHG, and comply with environmental standards that should have been in place all along, but are only possible now after the Climate Bill.

Honestly, people here are so opposing of something they didn't get to reap wild benefits from and dismiss it entirely to their own detriment because if they really cared about what is discussed in the most recent heatwave thread they'd be capable of looking beyond their own biases and see a much more viable network to bring about effective solutions towards climate change.

Slackware might have worked too. I haven't tried Slackware 15, but when i was developing Post Apocalyptic Petra[0] (a DOS game for an MSDOS game jam) a couple of years ago and was trying to do some performance profiling, i did try the immediate previous version of Slackware in 86box emulating a 300MHz Pentium MMX[1] and it worked fine (though sadly "prof" didn't work since it required some functionality introduced in later CPUs, so i couldn't do the profiling).

I do remember that i had to replace a file in the ISO for it to boot (it was a mistake on Slackware's side and there was a patch for it in the forums) but i think this was patched in "current" so Slackware 15 should not need it.

Surely you’re not as Irish as the Irishman in the article…who lives in Britain…and served for 30 years in the British Army…?
Given the sheer number of headlines like "<This invention> will change the face of <this well known thing>" that really boil down to "<This idea, which isn't even new> is interesting to think about, but won't really have any impact on <this well known thing>"... it really doesn't make one ill-tempered to bring up for discussion whether the current article is one of those.

It might not be one of those, and it's not fair to assume it _is_ one of those... but discussing whether it is or not isn't rude/mean, and probably _should_ be standard practice.

I don't think this is totally on the media. The story is sufficiently weasel worded -- the motor "could" "pave the way". Anybody with any experience reads "could" as "probably not" and "pave the way" as "a tiny little step in a long process".

Most 6 year olds have figured out that "maybe" means "probably not". Many adults have forgotten that lesson.
FYI: your common sense idea conflicts directly with other HN members' comparably sensible idea that devices are the property of their owners and shouldn't have any vendor or regulatory constraints on how they're used and what runs on them. And of course the middle ground people will say that users can just have the option to unlock their devices, and contrarians will respond to say that any unlock feature becomes a vulnerability to plain-as-day social engineering and therefore defeats the purpose. etc etc

Indeed! It's a really interesting usage. Maybe it developed in a similar way as "badass" to convey a sense of (positive, approved) vaguely dangerous wildness and coolness.

It kind of makes sense here -- Hetzner's competitors probably hate this "notorious" behavior of being so good at ruthlessly[1] slashing prices

Yes but every year that goes by that market shrinks as new fibre gets rolled out and 4G/5G continues to grow in service. I don't know if it really is enough of a market to cover the cost of servicing thousands of small sats long term.

The global angle is interesting; but I don't think Africa will be as simple as people make out - there is a lot of corruption around telco contracts there and they won't just allow SpaceX to turn on all of Africa and bypass it all.
I think a few more concrete use cases would help.

First, a key limitation that every architect should pay attention. Redis reaches the limits of what you can do in well-written single-threaded C. One of those limits is that you really, really, *really* don't want to go outside of RAM. Think about what is stored, and be sure not to waste space. (It is surprisingly easy to leak memory.)

Second, another use case. Replication in Redis is cheap. If your data is small and latency is a concern (eg happened to me with an adserver), then you can locate read-only Redis replicas everywhere. The speed of querying off of your local machine is not to be underestimated.

And third, it is worth spending time mastering Redis data structures. For example suppose you have a dynamic leaderboard for an active game. A Redis sorted set will happily let you instantly display any page of that leaderboard, live, with 10 million players and tens of thousands of updates per second. There are a lot of features like that which will be just perfect for the right scenario.

Migrations aren't ideal, but I'm excited to see continued innovation in borrow-checking. This is a major area where Rust is exploring truly new territory as a language, so growing pains are to be expected, and it's encouraging to me that Rust's semantics allow borrow checking to keep getting better without breaking changes
It's good they're giving us a choice, maybe. But the offered service is actively getting worse due to the addition of that choice, because the current paid tier will now include ads, rather than them introducing a cheaper tier with ads.

Nope, he uses C code that is also valid C++, to produce an argument why C better than C++.

But then he wouldn't be able to use "C is better than C++", when using stdio for both languages.

A healthy lifestyle definitely helps, and some genetic luck. My grandfather recently passed away unexpectedly at age 88.

He was working in the garden daily or going for walks / riding a bike. He had a more active social life than I did before COVID hit. He read daily, did crossword puzzles at night, and ate healthy. No mental or physical issues.

Lifestyle plays a role, but he was dealt good cards genetically as well which I am aware of.

> In my view, in a healthy organization, the meeting itself should be a point of collaboration. Otherwise it's a waste of time. This culture of behind-the-scenes-go-betweens also creates a lot of opportunity for opacity and malicious miscommunication (deceit).

Yes. At the same time, collaboration is limited when you need a lot of one-on-one discussions that are mostly relevant to one person.

You can have those one-on-ones as a part of a larger meeting. But is it optimal? I'd say no. During a meeting attention is limited. You can tackle one problem at the time and can't do them in parallel. If you have multiple problems to discuss where there's one stakeholder, it's a waste of time for others. A meeting that's a collection of queued one-on-ones is not efficient. An efficient meeting is one where every spoken sentence affects every participant.

Bulk of the project progress is done in the trenches, so to speak. Moving it to meetings makes them longer and more frequent. If someone waits for a meeting to drop an unexpected bomb for the whole team, it likely won't be resolved then and there. After all, others weren't aware so they didn't have time to prepare. Asking people to improvise on the spot is not a good idea. I'd argue that giving others as little time to prepare as possible is a symptom of an adversarial environment.

On the other hand, sharing things in advance gives everyone time to digest them.

Perhaps rewording the statement would work. How about "you should go into meetings only if there will be no surprises".

Even though you're happy in every day life, it sounds like you could benefit from some therapy to help you unpack those painful memories. Moving past that might help your creativity flow.

When my creative juices feel depleted, I give myself permission to do nothing. Take a long walk, play a game, watch a movie, but don't make anything. I usually find that relieving the pressure of feeling like I should be more productive actually makes me more productive.

Happy with the Flip 3. It is small in the pocket. I can check messages and new emails without unfolding. I can even do NFC payments while it's folded up.

Besides that, I can stand it on my desk with the screen towards me, which is very convenient when doing things on a computer and the phone simultaneously (like 2FA authentication).

Can't think of any downsides to a standard phone really.
