I use it mostly to assist my fiction writing. Helping me brainstorm, critique, work through stuck-points, and proofread. The other day I was a bit stuck on the main conflict of a story I'm writing and talked through it with ChatGPT via voice on my phone on a bus. Then I had it output a revised outline of the story with the changes we just discussed, and give me word count targets for each section. I also generate character illustrations in the same thread. I've uploaded my existing books in the same series to this custom GPT, so it has background information on the series tone, characters, etc.

For programming tasks, I use GPT-3.5 and 4 indirectly via Cursor and GitHub copilot (both Chat and inline suggestion features). It's hit and miss for this, but useful _enough_ to be worth it as long as I'm prepared to be vigilant and do a lot of handholding.

Oh, I should have clarified - could one start with a bfloat16 on software-side, convert to float16 (so that e.g a 3.4E38 float16 becomes a 65504 float16), then do any "heavy math" in fast hardware float16 instructions, and then convert back at the end?
At that point, probably both M1 and M2 will be outdated. And people will sell their outdated laptops and buy M5 or M6 laptops.

Depends on who you ask. For the grid operators since they balance instantaneous supply and demand they only care about power available. Expecting the producers to maximize their profit and hence save the batteries until they are most needed.

When explicitly designing an electrical system, say an off-grid cabin, both the energy stored and instantaneous matching of supply needs to pencil out.

In the large scale grid example we expect the market to handle the energy balance. Adding transmission links, secondary markets and so on when the market does not adequately match demand.

Generally speaking today batteries used for grid scale storage store 4 GWh per 1 GW. This number comes from maximizing the utilization of the grid connection and matching the hours per day with highest electricity rates.
It is among some south europeans, such as greek or portuguese. The few english people I met there were happy. Unironically, they were happy they earned a higher wage and could afford property. But that was in bucharest. The most portuguese I met were in Cluj Napoca. French students have also been known around expat circles. Reading stats, it looks like minimum wages are nearly six times higher than Russia's for instance, and average pay twice as much. Also seems to be a high income economy, with increasing numbers of non EU immigrants, from India and Vietnam.

Not that they are in the millions though. But nonetheless the state of affairs in the UK is extremely bad.

Doubtful. I'm not sure they have the talent/knowledge to pull it off while Apple Silicon is a moving target with a new generation introduced in each new iPhone.

Is this true? I don't think so. When they buy a public company, both sides surely have investment banks that help them to correctly value the deal.

Also, "pays below market prices" is probably commentary about his value strategy.

Raspberry really needs to pick up the pace to compete with newer (albeit more expensive) SBCs with Intel N100 and similar processors. The TDPs are very comparable, but the x86_64 still blows it out of the park performance-wise. Also, software support is a non-issue on Intel platforms, which still is not the case for Arm platforms.

It's a phrase that pretty much every major American politician has used. Of course there are dog whistlers and conspiracy theorists, but I think the less problematic usages predominate. Not that the phrase really means anything as far as I can tell, but that's a separate issue.

I do see what you mean though. There's something inherently gross about juxtaposing two sentences like that. I'm not doing it to suggest any equivalence between them. The point is exactly the opposite (and I would have thought an uncontroversial one): that switching out the major vocabulary items in a sentence can take it from being innocuous to offensive or vice versa.

Old news, posted already a few days ago
Yes, but this seems fairly off topic when my complaint is about Slack and general software bloat. I know there exists responsive software, but much of it isn't.
It does support USB-PD. It just doesn't do it in a way that many USB-PD power supplies work with.

Whereas lots of USB-PD devices (at each end) will negotiate higher voltages in order to accomplish greater power delivery, the Pi 5 only ever wants 5V -- not 9V, not 12V, 15V, not 20V, and not PPS.

Ideally, it wants up to 5A of 5V.[1]

And many (I dare say "most," or "nearly all") USB-PD power supplies top out at 3A when in 5V mode.

Also: Getting 5A of USB-PD also requires a special e-marked cable because that's getting into the realm of current flow where things can get melty. A dumb cable will never be expected to transmit 5A of current with a USB-PD device at each end.

---

The Pi 5 still can still work even if it can't detect that it is running from a 5 Amp-capable supply, though. It may be slower (due to detected voltage sags), and there will be less power available for USB devices attached to the Pi (which can be toggled in config.txt). But it can work.

It can also be powered through the GPIO header, just as other models in the past: Nothing prevents those who think they know what they're doing from using whatever they have laying around that they think is adequate, and just powering the device up in full capacity.[2]

For one thing an 18 wheeler has 10 brakes, not 18. So that's an obvious thing to fix.

The weight of the truck acts as an acceleration force when going downhill. The tire friction of a car and truck is the same - but then the truck has extra force trying to accelerate the vehicle when it's downhill.
It will consume a lot of power. But there are alternatives, depending on what language you are programming in, how challenging the tasks are, and how powerful your laptop is.

Take a look at r/localllama on Reddit. I have heard good things about the DeepSeek Coder and some others like Mixtral or larger models such as Codellama or Llama 70b (which probably won't run on your laptop).

My laptop is a bit old and doesn't have adequate memory to run models large and sophisticated enough to make it worthwhile for my programming tasks.

It's crazy to think that just one week before all of this started me and my girlfriend were hiking to Gunnuhver hot springs and stayed at pretty much the exact spot over the night where the eruption happened next to Grindavik, mostly because there's nearly absolute darkness ... except for the bright light above Grindavik that looks like an island of light in the middle of nowhere, it was really magical.

Iceland is such a beautiful place.. although I was angry and sad for most part of the trip seeing how tourism changed Iceland over the last 20 years. As recently as 2014 we had to ask the locals in mostly sign language and paper maps how to navigate the Westfjords; there's 5G now in even the last corner of the island.. guess I'll need to resort to Svalbard and Greenland to go truly off-grid in the future :-)

As a young child, one day at school we had to fill in a "travel to school" questionnaire. I remember finding it funny that one option was "hovercraft", when the only one applicable to me was "walk".

Years later, I lived on the edge of Southsea Common in Portsmouth, and would regularly walk past these hovercraft terminals. The hovercraft do make quite a roar, as the article says, but were always fun to watch. I especially enjoyed "take-off" (if that's the right term?) when they would slide back off the beach into the sea and do a 180 simultaneously.

They do like to advertise the Portsmouth hovercraft service as being "unique", and say that no where else has such a service. So it's interesting to read that hovercraft are being used for regular services elsewhere in the world, such as in Japan, "to deliver passengers straight to the doors of the airport terminal across the Oita Bay without the need for a quay or even a connecting bus." Clever!

Several times I got the hovercraft in Portsmouth across to the Isle of Wight. One time I recall seeing a group of school children, presumably on their way back home to the Isle of Wight after a day of school on the mainland, and it brought back memories of my childhood questionnaire. I guess that option wasn't quite so ridiculous after all.
If so, you need to adjust your critical thinking skills. Deeply unnuanced posts about highly debated topics - like the one you replied to - should set off alarm bells.

That’s a beautifully produced magazine.

I’ve lived in Japan for forty years. While I would not consider myself a train enthusiast, it’s hard not to get affectionate about them after having ridden them for so many years. My four-year-old grandson, who lives with me, is definitely already a fan. He can identify dozens of different trains and train lines, and currently his favorite song is about railway crossings [1]. It helps that we live a five-minute walk from one of the busiest places for trains in Japan [2].

For his birthday last month, I bought him a huge, incredibly detailed picture book about trains [3] that we have been reading together. It will be interesting to see how his interests evolve as he gets older. Fans tend to focus on particular aspects of trains—riding them, photographing them, recording their sounds [4], learning their schedules, etc.—and there are terms for each type of enthusiast [5].

What, you never heard of them doing big concrete pours when building the classic performance houses in the 1800s?

Lifelong passion projects really resonate with me (sorry) and frankly, I have no doubt that this guy knew 10x more about sound systems than both of us put together.

My frustration is that I think this kind of extreme audiophile stuff is a legitimate mental illness. The sad truth about the fireplace and the porcelain dogs is that no, it literally doesn't make any difference that a human could perceive. Put them in or take them out, there's no way a 70+ year old man could tell you if he was blindfolded.

Still, I'm glad that he finished his project. Getting 4-5 years to enjoy something like this puts him in an incredibly rare demographic of human.

Squint, and I see Colin Furze's ever-growing tunnel system under his house in the same light.

Yes, 90% of companies do not check where you are from and will comply with your request, however data brokers and other companies who's business model depends on personal data usually do check just to add more friction to the opt-out process. Still, I recommend trying.
If the sample clock edges aren't very (very very very) regular, on a sample-and-hold ADC, the waveform isn't sampled evenly and that manifests as noise that swamps the detail provided by the higher bit depth.

This is called "sample aperture jitter". Requirements scale linearly with frequency and exponentially with bit depth.

These a calculator here:

https://www.analog.com/en/design-center/interactive-design-t...

https://www.analog.com/en/technical-articles/aperture-jitter...

Sure enough, 32 bits sampling a 96kHz signal, which is the Nyquist frequency of 192kHz sampling rate, is 0.3fs. At 24 bits, it's more like 100fs, which is much more doable, but still not easy.
Which is why audio bit depths usually don't go to 32 bits, despite formats like FLAC supporting that.

The practical upshot of this and other noise sources is that higher audiophile-grade bit depths and sampling frequencies are quite likely to have at least some of those bits swamped out by noise on real hardware.

This is just getting the audio recorded. Playing it back as physical sound waves adds something between quite a bit and radically more noise to the signal, even if there's never any lossy compression.
I assume your suggestion here is just to embrace a framework for data fetching and try not to think too hard about how they in turn implement it?

Can't really fault developers for falling into this useEffect trap when even the official docs show that data fetching is indeed handled via useEffect[1], while at the same trying to yell at the reader to "NOT TRY THIS AT HOME" and just go use a framework because it's such a complex problem... which naturally just creates more questions than answers for the poor developer trying to understand how it all works.

Exactly, especially with some types of batteries this is relevant. Redox flow batteries that are being experimented with for grid storage now use a reservoir for storing the anolyte and catolyte fluids. The bit that allows those to interface where the power is generated is much smaller though. So you can take the same battery and trivially double or triple the storage capacity by simply using bigger reservoirs and more liquid but the power delivery would stay the same. These types of battery are potentially great for longer term storage but they aren't necessarily able to deliver the stored energy quickly. It could take days/weeks to deplete them and a similar amount of time to charge them back up.

Lithium ion grid batteries are sort of the opposite. They can deliver a lot of power but usually only for a few hours at maximum capacity until they are depleted. So, you see companies install a few hundred gwh of capacity being able to deliver most of that power in a few hours.
