I think we witnessed a profound paradigm shift last week - China is the new global driving force to avert climate catastrophy. The probably peaked CO2 output last year. Last yeear they reached their 2030 target for renewables as share of total energy production. Almost 60% of new cars sold there are electric. And China produced more PV cells in the first half of this year alone than have been installed in the US in sum, ever.

And now they stated a public CO2 reduction goal for the first time.

I suspect people in the US haven't really noticed this as much because the 100%+ tariffs on cars and PV isolate the country from the dramatic changes happening everywhere else. Here in Germany I can buy 2 kWp in panels plus an inverter for under 400€.

No they should really really be discussing things like this.

This is like trying to claim bioethanol is somehow carbon negative.

It's broken from a farming standpoint (and we're a nation starting to face issues with production. Notice how I say starting not we're starving there's several world's of different yet)

It's broken from an economic standpoint because you're going to try and take on the whole of Asia who could crush you in a single shipment.

It's broken from a mindset perspective. British wine may be one that grabs interest over here like British vodka. But people will not pay 10x or more for British rice. It will be seen as a stupid concept or idea.

It's broken because again... Who in Britain is clamouring for more rice options? This is a product type which is already over saturated at the normal supermarket, let alone the choices when you're willing to shop online.

If there's no discouragement to projects like this idiots will run the land into ruin, lose a lot of money. Drive away needed capital from farms looking to turn around their fortunes and damage the sector.

I'm not saying British farms are about to collapse and we're all about to starve here, but the sector is struggling.

> Did you ever use DSL?

Where I live (Germany), lots of people have vDSL at advertised speeds of 100 Mib/s, using pair copper wires. Not saying that fiber is not better, it obviously is, and hence the government is subsidizing large-scale fiber buildouts. But as it stands right now, I'm confident that for 99% of consumers, vDSL is indeed enough.

In the 90s and 2000s, I remember our (as in: tech nerds') argument to policy-makers being "just give people more bandwidth and they will find a way to use it", and in that period, that was absolutely true. In the 2000s, lots of people got access to broadband internet, and approximately five milliseconds later, YouTube launched.

But the same argument now falls apart because we have the hindsight of seeing lots of people with hundreds of megabits or even gigabit connections... and yet the most bandwidth-demanding thing most of them do is video streaming. I looked at the specs for GeForce Now, and it says that to stream the highest quality (a 5K video feed at 120Hz), you should have 65 Mib/s downstream. You can literally do that with a vDSL line. [1] Sure, there are always people with special usecases, but I don't recall any tech trend in the last 10 years that was stunted because not enough consumers had the bandwidth required to adopt it.

[1] Arguably, a 100 Mib/s line might end up delivering less than that, but I believe Nvidia have already factored this into their advertised requirements. They say that you need 25 Mib/s to sustain a 1080p 60fps stream, but my own stream recordings in the same format are only about 5 Mib/s. They might encode with higher quality than I do, but I doubt it's five times more bitrate.

Thanks a lot for the kind words! I totally get what you mean — having to sign in to Adobe Cloud just to do something as simple as turning a video into a GIF feels like overkill. That frustration is exactly what pushed me to make ConvertFast: no logins, no internet, just open the app and get the job done.

I’d be curious to hear how it stacks up against your Adobe Media Encoder workflow once you give it a try. If there are specific conversions or settings you use often (like GIF export presets, compression levels, etc.), let me know — I’d love to make sure ConvertFast covers those cases smoothly.

Appreciate the support, and I hope it really does save you some time (and sanity) once you try it out!

It's called "pragmatists versus theologians" (or fundamentalists, depending on the translation), and it was extremely common in any left wing movement in Europe from the '60s to the '90s.

Umberto Eco wrote a fair bit about it. it's not exclusive to left wing movements but historically has been very apparent in such groups[1].

In short, You got a group of people whose main objective is to improve the condition of their community and it's inclined to bend the purity of their message in order to achieve some realistic objective (to the point sometimes of fully betraying the original ideology altogether)

And then you got a group of people whose idea is that philosophy trascends their or anyone else life, and the point is the fight itself. As an italian song of the '70s cynically puts it (very loosely trasnlated) "The fight has to be endless, comrade, otherwise I won't be a general for the people anymore."

Truth is, you need both of them to make a movement capable of actually going somewhere, despite ironically having in itself the main cause of its own collapse.

I'm not sure if it's purely down to "hype".

For me I do tend to prefer apps written in rust/go(/c/etc-copiled) as they are usually less problematic to install (quie often single binary; less headache compared to python stuff for example) and most of the time less resource hungry (anything JS/electron based)... in the end "convenient shortcut to convey aforementioned benefits" :)

I don’t want a laptop dock. I want to be able to connect my phone to the dock I already have on my desk or carry with me a foldable screen and keyboard when I need portability. That would give me a larger lighter screen that a MacBook and a better typing experience. I already have headphones. I already have a secondary battery. Actually make all of this wireless and that would be perfect. Plus if the screen support touch you have a tablet.

The laptop has a device makes less and less sense now that the cpu and gpu inside a phone are good enough for most. It’s propped up only because phone providers artificially limit what the software on the phone can do.

> for me that's _peak incompetence_

Empires always fall from within. It was inconceivable for a young me to ever think of day when MS Office would be unworkable. Advance couple of decades and MS 365 Copilot is just the thing that just doesn't work. Not because somebody exploited a bug and created unviewable doc, but because MS decided to pile on bugs while leaving old ones in..

Have you been paying attention to the farming sector in the last 5yr?

There's plenty of problems reminiscent of the 30s after the whole chain has been kicked around due to labour from Brexit, supply due to Brexit, access to markets from Brexit and then the joy of dealing with the cv19 lockdowns.

The sector is still facing real financial problems and none of the last few governments have seen farmers as anything other than land owning cash cows.

The US has turned to authoritarianism. It seems naive to think this is going to go away in an election.

Our government is owned by the ultra wealthy who pursue their own narrow interests at the expense of the common good. Some of these people are just cynical; others identify their narrow interests with the common good. In either case they’ll continue to steer our world toward self destruction.

The best thing to do isn’t to hide one’s head in the sand or place our faith in failed institutions. These are two kinds of denial. We should be building a base of popular power in labor unions. The ideology is solidarity and striking holds actual power over the ownership class. It’s really the only thing that has a chance of leading society out of the collapse we are witnessing around us.

> It's not fun to have to trace through 5 or 6 different functions to try to figure out what type is being passed in or returned from something.

My position is that what is intended must be made clear between type hints and the docstring. Skipping this makes for difficult to read code and has no place in a professional setting in any non-trivial codebase.

This doesn't require type hints to achieve. :param and :rtype in the docstring are fine if type hints aren't present, or for complex cases, plain English in the docstring is usually better.

> In Spain and Portugal, the word for @ is "arroba", a term related to amphora that is also a standard unit of weight and measure.

It is in fact still used in certain contexts. For deciding when to slaughter the Iberian pig after feeding it exclusively with acorns in the open, it must weight 9 to 10 @s (an @ is 11.5kg, so 103.5 to 115kg)

> Perhaps you should stop listening to propaganda from the ubranists

I know this site is US-centric but excuse me if I don't take anti-public-transport propaganda at face value. I've lived in Europe all of my life and I've been to major US cities on the west coast so I've seen great public transport as well as the car-centric culture with my own eyes.

> Yep. That's how bad buses are.

No, that claim is ridiculous and obviously incorrect - It's laughable, really. Care to [try to] substantiate it?

> One bus does the same amount of road damage as 1000-5000 cars.

Sure, buses do cause more road damage than personal vehicles, but that's hardly a significant factor. Care to list all of the externalities for personal cars? Does parking build and maintain itself? How about all of the opportunity cost for space occupied by parked cars? Injuries caused by impaired drivers?

> A well-designed city like Houston will have enough road space so that buses are do not affect the traffic disproportionately. But then it means that such a city does not _need_ buses.

I have no idea what you meant by this. That doesn't logically follow.

> What I have to have scientific papers for every fucking opinion I have?

No, but if you’re going to say things like “increase safety by roughly 2x” then if you can’t even identify the unit then you are misleading people.

It’s absolutely fine to have an opinion. It’s not fine to make numbers up.

> I'm confident my "anecdotal" metrics with I prefaced with "roughly" are "roughly" ballpark trueish.

Okay, so if it’s 1.5×, 2.0×, or 2.5×… again, what metric? What unit are we dealing with?

You’re claiming that it’s “in the ballpark”, but what is “in the ballpark”? The problem is not one of accuracy, the problem is that it’s made up.

> If someone disagrees with me (on this specific topic), it absolutely doesn't mean they are a junior. It means they lack knowledge and experience. This is a fact.

It’s not a fact, it’s ridiculous. You genuinely believe that if somebody disagrees with you, it’s a fact that they lack knowledge and experience? It’s not even remotely possible for somebody to have an informed difference of opinion with you?

What does

>The pins that were supposed to nestle into the motherboard were instead pointing skyward

even mean? How do you physically solder a chip the wrong way around?

The story seems totally unbelievable. This is a training session, someone asks a potentially reasonable question and then is just let go? Hiring people is expensive and letting someone go over something like that is ridiculous.

The story isn't even alleging that the manager disagreed or that the manager tried to argue there was no defect. If you take the story as told it is completely nonsensical.

> Multiple studies have shown that the vaccines significantly reduced infection rates.

Is this true or is this rather being asymptomatic or symptoms not severe enough to warrant seeking medical advice and not getting tested in the first place. Seems more like correlation than causation, I can argue that any day.

> If you have a specific region in mind, do you mind elaborating?

Where I live, South Africa. If you refused to get vaccinated during the pandemic you were forced to remain in quarantine despite taking every required precaution and for many large companies were not allowed to return to work, you were given an ultimatum, vaccinate or quit.

Your last point has no merit, I suspected but couldn't prove so it was nothing more than a suspicion, having actual studies prove it is a different story.

If/when the AI bubble bursts, I don't think AI will just cease to exist. It is difficult to imagine a world without this tool now - it is a great convenience. Now, is this convenience worth almost $1 trillion? No. At least not yet - if ever. Very gimmicky solutions are being peddled and there seems no concrete class of problems found for this "AI solution." Replacing entry level human interaction perhaps. But that won't earn companies money in the long term - just short term savings. And for every profession that uses AI in the senior positions as an aide, it chokes off entry level pipelines. So difficult to tell how this will play out.

Please ignore my first assertion that the behavior between REPL and module is different.

This would have been the case if the semantics of the original PEP649 spec had been implemented. But instead, PEP749 ensures that it is not [0]. My bad.

I think your valuing of moves is flawed. Yes, during the fuseki the best move may be worth 20 points. But there are often many moves that may be worth 19 or 18 points. So, playing perfectly only gains a few points compared to playing acceptable moves. In comparison, tactical situations often have a crucial move that wins many points - in low-level play swings of over a hundred points are not uncommon. There, missing the crucial move can lose the entire game, no matter how perfect the opening was played.

All solar panel datasheet have temp coefficient, eg for one random ecoflow solar panel:

Temperature Coefficient Specifications TKPower -(0.39±0.02)%/k TKVoltage -(0.33±0.03)%/k TKCurrent +(0.06±0.015)%/k

source https://websiteoss.ecoflow.com/cms/upload/2022/10/15/-139121...

STC ("standard testing conditions" for solar panels) is 25C so if it's freezing 0C you have 25 multiplied by 0.33 Volt = 8.25 Volt more than STC in open circuit situation.

Unfortunately inverter manufacturers seldom document how many Volt will destroy the MPPT and up to how many Volt the MPPT will safely turn off by itself before breaking.

It's perfect on the almost square-ish main screen of a foldable.

In fact, it's the best looking game experience on a foldable I've seen so far (most games are designed for either mobile or tablet form factor, and can't quite handle the in-between). And it's cool how you can just fold or unfold the device on the fly, and the game just adapts without anything more noticeable than the camera pivoting a bit if needed to keep the character on-screen. No stutter, no half-second pause for UI to realign, not even perspective change.

EDIT: I just realized it's probably not a mobile-specific thing, and sure enough, on a desktop you can just resize your browser window to see this.
Show HN: CLIPSQLite – A SQLite Library for Clips Resources Readme
by ryjo | 2025-09-28 11:00:05+00:00
Hey, HN!

CLIPSQLite is a library for working with SQLite databases within CLIPS rules engines. It provides the basics like opening and closing connections, as well as more advanced ones like binding named variables to prepared statements and returning results as Facts and Instances.

Aside from being a lot of fun to create, my goal in making this is to open up the possibilities of using CLIPS in real world systems. Give it a look, and let me know what features you'd like to see added next!

Funny you should say that about the procedural debate, because I actually have the other opinion about that! The role of a steering committee is to make high-level decisions, and delegate delegate delegate: having direct involvement is a warning sign, and the few instances I've seen of that have gone really badly. (That said, I don't know what it's a warning sign of.)

> If that were truly the LLM's "paperclip", then how far would it be willing to go?

While I'm assuming you didn't mean it literally, language is important, so let's remember that an LLM does not have any will of its own. It's a predictive engine that we can be certain doesn't have free will (which of course is still up for debate about humans). I only focus on that because folks easily make the jump to "the computer is to blame, not me or the folks who programmed it, and certainly it wasn't just statistics" when it comes to LLMs.

The voltage ratings of the MOSFETs used for 220/230/240 V applications have been increased over the years.

Decades ago, when bipolar transistors were used, they were rated for 350 V, which is barely enough for 220 V + 10%.

When everybody started to design universal converters usable for 220/230/240 V, the ratings were increased to 400 V. The first power MOSFETs were also rated thus.

Then there were too many converters destroyed by random voltage spikes, so the standard ratings were increased to 500 V. That proved to still be not enough in many places over the world, so the ratings were increased to 600 V or 650 V, already many years ago, in order to make extremely unlikely the destruction of the transistors by voltage spikes much greater than the nominal mains voltage.

600 V or 650 V is used for converter topologies where the transistors see only the peak input voltage. For converter topologies that use fewer transistors, but those see peak-to-peak voltages, the rating of the transistors must be 1200 V.

For 650 V, gallium nitride FETs are the best available devices, while for 1200 V or higher voltages silicon carbide transistors are the best. Silicon transistors are the best only for ratings much lower than 100 V, but they may be preferred also at high voltages for being much cheaper.

> Sure, that's one way to put it. If you don't know the topic you're reporting on,...

Am I missing some irony or subtle sarcasm here? You're attacking the BBC for being inaccurate - with an argument containing a claim which is not just inaccurate but completely false - about the habitats which support growing bamboo.

> and I can smell the BS already

Where is this BS? You haven't identified a single sentence containing a scientific inaccuracy as far as I can see.

"Smell" is a weasel word - a way of avoiding the effort of actually presenting an argument or evidence - or even using the opportunity for some introspection about your own emotional reaction to an article because it mentions climate change.

I've read the article - it uses the usual light entertainment style favored by the BBC - which is the reason I don't bother with the BBC at all. But unless you're actually offended by being reminded of the existence of AGW, I can't see anything at all offensive, inaccurate or false in it.

Science journalism has a lot of issues but I think those problems are across journalism and not especially unique to science. Over referencing familiar narratives, click bait headlines, piss poor editing...you'll find this in all types of news out there.

Should science journalist hold themselves to a better, special standard? True. Especially with the age old war that's waged on it by those who hold power through selling incredibly unscientific world views. But I think the overt actions these forces are more to blame than poor science journalism. People don't like inconvenient facts, people will forever be victims to a voice making a problem go away by denying the problem even exists.

Not my study, and even a single cancer is more than needed, even if treatable. Do you know how much cancer treatment costs? The psychological toll it takes on those diagnosed and those around them.

I'm not arguing for not getting vaccinated, I'm arguing it should not be mandated for people who have no need to get vaccinated because the actual stats show they are not at risk or getting a severe infection in the first place.

It's not a matter of their risk increased but it is fine because they had greater risks to mitigate. It's just a base line increase in risk for dubious benefit.

I was vaccinated, I still got full blown covid after vaccination, I was still infectious and had to quarantine and I still live with the long term effects of having had covid, the vaccine was pointless for me and on top of that just increases my baseline risk.

The physical card is sufficient to prove you have permission to drive. This code is for them to check how many points you have on your licence and what for. There used to be a paper counterpart to the card which showed this which they withdrew a few years ago.

In reality I've never been asked for the code when renting cars (outside the UK), the physical card seems to generally be sufficient for the hire companies.

It is amazing to see a modern take on LaTeX.

Previously I had great success with LyX (https://www.lyx.org/), which builds on top of LaTeX. The experience of typesetting beamer slides with it is relatively user-friendly.

A decent usage example of Typst is https://rendercv.com/. It is a set of Typst templates to build resumés.
