"Additionally, to protect vulnerable population groups, especially pregnant persons, babies and young children, the last remnants of lead pipes that were installed more than 50 years ago are to be removed from house connection pipes or domestic distribution systems by 2026 unless already done"

So in the mean time, because you refuse to have an in home filtration system, enjoy the free lead additives until your government gets around to your pipes. Or, use an in-home system and enjoy unleaded water now. If you can't understand that, then you are just being willfully ignorant yourself

Seems like a great time and place for the iron air batteries that are getting deployed now (Form Energy). Even in the US, without Dunkelflaute, these 100:1 energy:power batteries are economical and paying for themselves on the grid. If there are several of these occasions per year it could be a great fit.

It also seems likely that HVDC from sunnier areas like Spain or maybe even Morocco could be cheap enough. I'd recommend nuclear but EDF is having such great difficulty building it. HVDC and other exotic solutions like enhanced geothermal seem for more practical at the moment.

Bear in mind that charging and discharging batteries has an efficiency penalty - perhaps 98% efficient for each. So 74 stored is worse than 72 used directly because 74 -> 72.52 stored -> 71.06 discharged.

And usually the efficiency is much worse than 98%.

Oh, and also batteries such as the tesla power wall can only be charged and discharged about 1000 times before they have lost a lot of capacity. So generating when you use also makes your batteries last much longer. You could think of this as a cost of battery depreciation per kWh stored.

The internal DAC in most of these microcontrollers is way too slow for VGA. According to this[1], for STM32 you can generally expect at most 1MHz without external additions; that's way too slow even for e.g. 320x240 which has a pixel clock of over 10MHz.

A lot of hobbyist projects use simple improvised DACs made with a few resistors. Here are mine for the ESP32[2] and the RP2040[3] (Raspberry Pi Pico), both use 320x240 (just the standard 640x480 with half the pixel clock and every line repeated to half the resolution in both width and height).

I think that "Boring work needs meaning, not tension" is a great explanation of bad bosses.

Any work will go a little faster when your boss puts an arbitrary deadline on it and screams "We need this by Friday, we're gonna tell the VP that it's late and it's your fault!!" But it's hugely demoralizing and stressful.

But if you say "this work will get the client's hospital equipment monitoring suite out sooner; if it works reliably, they'll be able to deploy it sooner, and it'll save the lives of some sick kids," then that'll also get the work done a little faster, and it'll make you feel good about doing it.

Arbitrary tension is a patch that you put on work that has no meaning. "We want you to go faster because it will make our metrics go up which might raise the stock a few percentage which might make our investors a few extra millions" has no meaning, which is the root problem.

today in the mediterainian grocery store they had "smog balls" candy, novlty product that has all kind of "warnings" about toxic waste on the package

so it realy looks like it is now impossible to tell just how pollution is/has effected the way we think, as where and how could we get a clear, clear baseline, and who cares anyway, it is guaranteed to get worse(long term average) everywhere on an continious ongoing basis, and the rest is pressure from nimby groups to relocate local sources, elsewhere, where perhaps it rains crap on there food

I am bipolar so I am naturally predisposed to needing less sleep during manic episodes. When I was 20 and unaware of my diagnosis but probably in a manic episode, I successfully maintained the Uberman sleep schedule for three months. Even for someone like me who can function well on minimal sleep, it was definitely challenging, but it's absolutely doable and does come with some real benefits, mostly productive hours. The biggest hurdle wasn't the physical demands it was the social impact. Having to tell guests that you need a 30 minute nap in the middle of hanging out is incredibly awkward. The schedule also becomes quite rigid because skipping even one nap really throws everything off. For me it was manageable but the lifestyle restrictions ultimately made it unsustainable.

There was a nice and friendly Usenet group. It's no longer active but archived here[1]. It has loads of information and journals of people that tried it at the time. Most of us also dappled with binaural beats (alpha, theta and delta waves) during the naps. They helped with falling asleep and waking up.

> Is this intended to be competitive with h.266/VVC? And is it?

Yes:

> VVC is not alone in the video coding race. AV1, backed by AOMedia, has already gained traction, although its performance does not make it a direct competitor to VVC in high-end applications. The upcoming AV2, as well as AI-driven encoding techniques, could pose challenges to VVC’s success. Nevertheless, VVC’s strong technical foundation, industry support, and clear intellectual property structure position it as a promising long-term solution for video coding.

* https://www.nokia.com/blog/the-future-of-video-compression-i...

> For businesses focused on reducing operational costs, this is a key point in the h.266 vs av1 debate. While the H.266/VVC codec offers powerful compression improvements over h.265, AV1—and eventually AV2—may be more attractive thanks to simpler licensing and long-term affordability.

Make sure they have at least a passing familiarity with Windows and it's apps because like it or not Windows is still the default in the school and working world so they'll have to work with that stuff to some degree. Otherwise go for it.

Side note how's open office compatibility these days? Last time I tried it yeeears ago there were still compatibility problems that would have made group projects hard.

No they are not equivalent. This came up with James Damore too.

Let's say there's a pool of 20 candidates, 10 male and 10 female. Since more men than women have an abiding interest in engineering, let us posit that 40% of the men are top prospects for the job, and 20% of the women are equally high-quality workers. The company is trying to fill 6 roles and has an internal mandate to hire 50% women. To serve that mandate, 1 unqualified woman will be hired, at the expense of 1 of the qualified men.

You can apply the exact same logic w/r/t race. Yes, there are legacy-of-slavery reasons why fewer blacks than whites are qualified for any given technical credential, but those are upstream of hiring decisions, and are not the job of e.g. airlines to solve, especially not at the expense of lowering standards for a crucial position like pilot.

A very ChatGPT thing to say. (half joking)

> It's not just tech that's changing, it's society changing as a result of tech (always has been).

True, and it goes both ways. As the cultural backlash to AI grows (see terms for it like Generative Slop, Bullshit Oracles, Regression Engines, etc) so too does people's desire to both identify and differentiate themselves from AI content and/or content that appears AI-esque.

So just know there is a significant subsection of the population that will clock such writing styles and will immediately dismiss and/or react negatively to your messages not on merit, but on "smell".

Ya, the OP is not telling the truth. One there isn't a "variety", second they aren't UL listed at that price. I've spent months researching this space for an off grid setup and these are the two best setups direct from China from a cost standpoint for 15 kWh. Neither are UL listed:

https://www.apexiummall.com/index.php?route=product/product&...

https://yixiangpower.com/products/yixiang-vertical-15kw-diy-...

Both would cost roughly $4800~$5500 for that total size.

If you want good customer service, dependable, UL listed, and correctly priced, then this is the king: https://signaturesolar.com/eg4-wallmount-indoor-battery-48v-...

UL listed ~45 kWh will cost you $10k, not $5.4k.

So, a lot of comments have already poked lots of holes in the article, but just wanted to chime in with a very basic observation: the mere statement that the 12k dimensions can pack in 10^200 concepts is staggering in how wrong it is.

Sure, 12k vector space has a significant amount of individual values, but not concepts. This is ridiculous. I mean Shannon would like to have a word with you.

To answer your question, I hardly buy anything with crypto because there's barely support... Hopefully this is a catalyst for change.

I feel like this is the wrong question to ask. Instead try "why would someone purchase with crypto over fiat?". I prefer to use crypto for international online purchases because the transaction and conversion fees from my native currency are way too high. With crypto it's a one off deposit fee and then gas is trivial these days.

"Those are functions of a marketplace"

Then it seems you should have said "If only there was a technology and a marketplace which fixes this..."

And no, it doesn't exist because handling disputes is a hard problem. It's the actual moat of PayPal (and credit card companies) and the reason why they can get away with their crappy behaviour.

> party name invented by Mussolini

Yes exactly that's what I meant with "concrete existing historical movement". I thought that would be unambiguous, what else do you thought I've implied?

It is however not exclusively used as a slur. What I hear more often from the mouth of politicians, is calling something fascistic, which means that is compared to it, so saying that X is using something from the playbook of the fascists.

This is why I am glad, that calling someone a Nazi is sue-able in my country. This means that we now have court decisions both for that someone is not a Nazi, it was a slur, and that this was punished, and also that someone is indeed a Nazi and is officially documented as such.

> as a symbol of penal authority

And this is actually a good description of what fascism stands for. I'm often astonished of how good self-labels actually are in defining and arguing against ideologies.

In fact you don't have to trust any of them, since browser root stores enforce certificate transparency.

But also the issues of segmentation are pretty much a total shift of the goalposts from what we were discussing, which is what actually happens when malicious activity occurs. In DNS, your only option is to stop trusting that slice of the tree and for every site operator to lift and shift to another TLD, inclusive of teaching all their users to use the new site. In WebPKI, the CA gets delisted for new certificate issuance and site operators get new certificates before the current ones expire. One of those is insane, and the other has successfully happened several times in response to bad/rogue CAs.

All of these metrics are just functions of a vector. Pop in an (x, y) pair and you get a number out. d₁, or as it's usually called, ℓ¹, |x| + |y|, gives you 7 when you pop in (3, 4). ℓ² = √[|x|² + |y|²] gives you √[3² + 4²] = 5. ℓ³ gives you ∛[|3|³ + |4|³] ≈ 4.498. None of them are moving or otherwise changing with time. They don't pertain to different numbers of dimensions; all of them are defined (in this post) as functions of two dimensions. They just assign a distance metric to every point in a two-dimensional plane.

I think where you're coming from is that the ℓ¹ metric tells you how far a taxicab would have to move, changing in one dimension at a time, while the ℓ² metric tells you how far you have to go if you go in a straight line. But the ℓ³ metric doesn't correspond to anything similar, not even in three or four or five dimensions, and neither does, for example, ℓ¹·⁵. To get to them you have to go through the formulas above.

The curves drawn are "level sets", which connect points that have the same distance metric.

The point of the post is not that "we can approximate [π] best" with a particular distance metric. Rather, it says that every metric (of this family of metrics—you can invent an infinite number of other metrics) has its own ratio of the circumference of a ball to its diameter, which we could jokingly call its "π", and that ratio is lowest for ℓ².

The ratio itself is a notion that really only makes sense in two dimensions; in three dimensions, for example, a ball has a surface rather than a circumference, and dividing the surface by the diameter gives you a length, not a number.

I am completely mystified by your remark that something "has everything to do with the nature of pi, not with the math". What is the nature of π if not math?

I feel this with every fiber of my being. I used to do a TON of front-end work, some of it quite cutting edge, delivering highly performant user experiences in the browser that had previously been only thought possible in a native app. Back in like 2009-2015. I was deeply connected with the web standards fundamentals and how to leverage them mostly directly.

I detoured into heavier focus on backend work for quite a while, concurrent with the rise of React, and watched its rise with suspicion because it seemed like such an inefficient way to do things. That, and JSX's limitations around everything having to be an expression made me want to gauge out my eyes.

Still, React pushed and laid the foundation for some really important paradigm shifts in terms of state management. The path from the old mental models around state to a unidirectional flow of immutable data... re-learning a totally new mental model was painful, but important.

Even though it's been chaotic at times, React has delivered a lot of value in terms of innovation and how we conceptualize web application architecture.

But today, when you compare it to something like SolidJS, it's really clear to see how Solid delivers basically all the same benefits, but in an architecture that's both simpler and more performant. And in a way that's much easier to organize and reason about than React. You still get JSX, server components, reactive state management (actually a MUCH better and cleaner foundation for that) and any React dev could move to Solid with fairly little mental re-wiring of the neural pathways. It doesn't require you to really change anything about how you think about application architecture and structure. It just basically does everything React does but better, faster, and with drastically smaller bundle sizes.

Yet I still have to begrudgingly use React in several contexts because of the industry-wide inertia, and I really wish I didn't have to.

Going on a tangent from a tangent, I think that the 2*12h clock is a horrible idea that should have been rejected from the start, and the Product Manager who proposed it 3 thousand years ago should have been immediately put into the dungeons and fed only once a day at 12PM. Anyway, now we know better and there's no good excuse not to use a 24h clock as the default across all systems.

Is it inconceivable that people actually see lower savings in exchange for tracking shopping habits is a beneficial transaction? Safeway can more effectively distribute products. I get to save money. Safeway has an incentive to keep this data secure - if it leaked then their competitors gain an advantage. And even if it does leak, how are my grocery shopping habits being published really going to negatively impact me? I mean, I guess I can see how a dieting influencer secretly buying donuts might be scandalous... but 99.9% probably DGAF if their grocery lists were leaked.

I often find that people just reflexively assume that data collection about their habits is inherently a net negative, rather than laying out the cost benefit analysis.

That 1000 is for NMC batteries and its a 70% capacity. Still enough to be useful.

Also, there's a lot of factors that go into play. For example, this assumes the batteries are fully charged and discharged. If you do something smarter like going down to 40% and up to 80% then they end up being able to do a lot more cycles. In fact, battery age starts mattering more than the cycles.

But besides that, LFP batteries are currently being used in home battery storage (including powerwalls) because it's cheaper and it has 5000->10,000 cycles before dropping to 70% capacity.

Generally, though, I'd agree that having more generation throughout the day is better than having perfectly optimized generation.

I never took it so literally. Just thought it was to develop a relationship with a mark and then put the screws to them as soon as possible.

Someone gullible, like a reality show contestant (90 Day Fiancé, Bachelor, etc). A person who can “fall in love” immediately and will do whatever to prove their affection because they believe they have limited alternatives.

A year investment…that is a meaningful (platonic or romantic) time for a relationship, where some sense of obligation/pity to the scammer could develop.

Exactly. This is what I want all my subscriptions to do.

In UPI (I know I know...) there is an autopay system. Your single UPI app has a single page with all your subscriptions. You can cancel or do whatever there and it's all handled in one place. My openai, streaming services, youtube premium, amazon prime, everything is on there. It gives me notifications before a charge is about to occur. No dark patterns.

This is the standard I expect.

Since credit cards don't provide a centralised thing like that, it's up to the SaaS provider to give the equivalent experience.

Cancelling should be _exactly_ as easy as signing up. If that means your MAU doesn't increase as fast, maybe you have a shit product. Case in point: amazon prime can have cancel buttons littered all across every page and I'm still not gonna cancel it.

Here's the simplest implementation: Few days before and on the day of charging, some infobox on the app's most attention-requiring screen, and an email telling me I'm gonna be charged. In all those communications, the main CTA should be a cancel button, that without further ado, let's me confirm and cancel the thing.

Anything even one step more complicated is a dark pattern.

Someone downthread mentioned - what if they want to change their subscription level instead of cancelling? In that case, two CTAs: change plan, and cancel. Both equally sized and right next to each other with good color contrast - important! None of that greyed out cancel button bullshit.

h266 (aka VVC) is seemingly ~~late in development~~ (edit: It has been released but doesn't have much hardware uptake yet). They probably want to ensure that people are aware that it will be matched so that they don't commit to it and AV2 ends up a bit late to the party like AV1 is compared to h265 where it had a notable compatibility lead.

If people know that AV2 is coming and competitive they may avoid adopting h266 and wait for the open alternative to ship.

No, I don't believe that a citation is the same as peer review, it is, as I understand it from the post you're replying to, an observation that other people have looked at it. (Indeed, if you actually go through and _read_ this particular paper, you can see that they also cite multiple reproductions and extensions of the paper. I would call that peer review—and certainly much better peer review than most nonsense that appears from committees. Ask me how I know.)

You mean instead of them running the code that they are writing they pretend to run the code and the model shows what it thinks would happen?

I don't like that at all. Actually running the code is the single most effective protection we have against coding mistakes, from both humans and machines.

I think it's absolutely worth the complexity and performance overhead of hooking up a real container environment.

Not to mention you can run a useful code execution container in 100MB of RAM on a single CPU (or slice thereof). Simulating that with an LLM takes at least one GPU and 100GB or more of VRAM.

It's been a pretty terrible day for the Web since webfonts were born then, since every site tries to force a single font to everyone for branding reasons alone. Case in point, Atlassian's hideous new font (which I've personally blocked using uBlock Origin, lol)

I do really wish that instead of moving in that direction, that customization was the norm, with sites specifying "serif" and "sans-serif" and users were assumed to be setting those settings to what they prefer. Similar to how dark mode is now respected on at least the plurality of "important" sites.

Use C++ bindings in libtorch or tensorflow. If you actually mean C, and not C++, then you would need a shim wrapper. C++ -> C is pretty easy to do.
