Thousands of cycles at what depth-of-discharge at what power? This use-case is pretty much the most aggressive, worst-case for batteries: ramp up to max power from a cold start, and then drain the whole thing.

The FAQ is also full of subtle weasel language:

> Our battery is designed to last beyond the average lifetime of standard appliances, and if a replacement is needed, the battery is modular and can be replaced upon request.

It talks about the battery being rated beyond some ambiguously-defined category lifetime. What is the "lifetime of standard appliances"? 3-5 years, going by average consumer dishwashers these days? That's not a lot for a $5k stovetop. Note though how they don't talk about THEIR appliance, and they don't talk about the battery being operated under THEIR usage.

My EV has a "10-year / 100,000mile" warranty, including battery, and they define battery performance as dropping below 70%. Unambiguous and straightforward. That the battery is the main justification of the price tag, they don't offer any specifics about the warranty, and they use ambiguous weasel language make for a huge red flag.

Best case: they're a startup and haven't figured this out yet. Worst case: the real-world performance will be a replacement money sink and this is vaporware. If you want to convince your early-adopters and instill confidence that this isn't expensive e-waste, offer a de-risking sweetheart warranty deal to your first batch of pre-order customers.
>Manufacturing never left the US - at $2.5T of output (2021) it's easily the highest it's ever been - almost 40% higher than 10 years previous.

It's not 40% higher in dollar value terms 10 years ago, that's for sure. You are leaving out the part about how the US dollar has lost value. Inflation is well in excess of 40% over the last ten years.
Re: shipping costs, see Universal Postal Union:

> The Universal Postal Union set up a fee so richer countries would pay more to have their international mail delivered than countries with developing economies.

> "The central idea is that any citizen or business should be able to send mail packages through the Global Postal Network to any destination," said Schoorl.

> At the time, China was considered a country with a developing economy, meaning the country would be charged less for international mail than other countries. And that went unchanged for decades.

> As e-commerce took off in the 2010s, China found itself with a major competitive advantage. It could ship to North America at a cheap rate. Canada Post and the U.S. Postal Service were delivering packages and not being compensated very well, says Schoorl.

* https://www.cbc.ca/radio/costofliving/shipping-canada-china-...

> China is still considered a “transitional” country by the UPU, which means it enjoys a lower rate for sending mail to a developed nation like the US. As a result, mail services from China to the US cost less than Americans are charged by their own postal service for a comparable domestic delivery. This gives Chinese sellers a competitive edge over American sellers, especially in e-commerce platforms like eBay or Amazon, where shipping cost is a major factor for buyers.

Are they not? What makes you think that? I honestly don't know myself, but am curious.

Maybe they already found all the high paying customers and now there's nobody left that will pay that much? No idea.
I too have been using this trick for many years on many cars since first seeing it done by Clarkson on Top Gear (circa 2006 IIRC and linked in the PSE question). I still baffle people with the considerable amount of extra range it can achieve. Half a football pitch was probably the best example I got on a 2008 Nissan Qashqai.

Check out what H100's are going for.

Also, as samspenc points out, that RTX 6000 is using the same AD102 chip found in a consumer RTX 4090, just with marginally more CUDA cores, TMUs, ROPs, etc.

The most substantial difference between the two is that the $10k card has twice the VRAM of the $2k card.

I know it sounds outrageously oversimplified, but Nvidia can indeed more or less print money by attaching a few extra memory chips to what is otherwise a flagship consumer-oriented graphics processor.

The profit margins on the H100, for reference, are estimated to be around one thousand percent (1000%), i.e., they sell for ~10x as much as it costs Nvidia to make them, and demand for them still grossly exceeds the total supply. See: https://the-decoder.com/nvidias-h100-gpu-sells-like-hot-cake...
Don't aluminum cans have a plastic liner?
Apple is the same as any car dealership nowadays. They give techs a very limited time, if any, to diagnose an issue. The solution is always to replace parts. Most of Apple’s solutions are replacing the logic board instead of fixing anything on it.

Once the computer is old enough I’d seek out an indie if possible, same for my cars if I can’t fix the issue or don’t have time.
Apple stands to benefit significantly as soon as they put base models for transcription, text generation, image generation, etc behind apis so their developers can leverage the latest improvements

When some of the best models are open source and allow commercial use (llama 2, Mistral), assuming there is economic value here [1], apple will be in the conversation

[1] feels like a big assumption, maybe! Isn't this just autocomplete? I think good semantic search is pretty valuable (as are other high level semantic concepts beyond similarity), but this is the part that needs more evidence for sure

Oh wow. I lived in the US for a year, so this doesn't come as a complete surprise. But Heatpumps? I thought everybody loved Aircon, regardless of polical party, or socioeconomical background.

This is just Aircon.

I'll despair with you. Unfortunately, trends that emerge in the US tend to find their way to the rest of the western world too..
I think it's largely a mismatch between type of manufacturing people want to see and type of manufacturing that's economically viable in the US. For example, people see low-margin consumer goods and electronics all the time, which largely come from China. But those same people only buy a car manufactured in the US once every decade and generally aren't buying Intel or TI chips directly. As another example, consumers are often oblivious to things around them that are made by GE.

I think the more interesting question is if it would even be economically possible to have a Shenzhen in the US, given US property prices, labor force, wages, environmental laws, zoning restrictions, etc.

I downvoted you because seeing conspiracies in progress is not reasonable. Heat pumps have been popular for a long time. Most of the houses around me have had them for decades.

This is a normal news cycle. A few articles pop up and then all the blogspam sites copy them. It's not a conspiracy, it's lazy publishers who won't do actual journalism combined with confirmation bias on your part.

And we have been using heat pumps for a long time in the US too. It is just that until recently heat pumps were not as efficient at lower temps and you would always have a backup heater source to heat during colder periods of the season.

Now heat pumps are able to reliably and efficiently heat most parts of the US. In combination there is a general push for electrification. We have increasingly cheap renewables, EVs and other interesting tech that in the electric space.

From a grid perspective over the long term it can make sense to electrify everything. You no longer need to maintain two energy types going to a home (thinking of natty or similar), you now only need to maintain an electrical grid.
Easy solution:

1) Be a good CEO
2) Don’t take on questionable board members.
3) Don’t take on questionable equity partners.

I don’t think this is easier said than done, just takes some discipline.
There are certainly exceptions, but in a very practical sense if the founder didn’t put the majority of capital into the business it’s unlikely and unrealistic that they’ll get some sort of special protection. The thing many founders struggle to comprehend when taking on outside capital is that there comes a point fairly early on when it’s not really your company anymore… you just work for it as a minority shareholder.

The other investors have a fiduciary duty to their own stakeholders that generally comes before the founder’s desire for special treatment. Good founders that know they’re not the right ones to lead the next phase of the business know when to step aside. Founders that don’t and try to cling on when they’ve long passed the threshold of their own competence to lead aren’t doing anyone favors by trying to cling on.

Over the years those processes have also frequently–at least for me–been the answer to “where did all my battery life go and why is my laptop so hot?”, as they’d rarely but inexplicably go haywire and peg the cpu at 100% until being killed manually.

Not inexperience. Motivated reasoning.
my take is that even without significant improvements over the current level of LLMs you are going to see significant impact on jobs and society over the coming years. There's so much low hanging fruit just by improving the UI around the existing models, I've seen prototypes that can automate a huge amount of grunge work and common manual workflows that office workers do every day. They just need to be integrated at the web browser or OS level so they can be used across apps and have some ability to preview/rollback any changes via human sanity check in the cases the AI agent messes up. Microsoft and Apple can destroy most of these AI startups by streamlining the workflow, Microsoft is already rolling stuff out. Apple really needs to back one of the open source models to support their on-device privacy message and include it with their devices as an improved Siri

and all of this is assuming we don't see the AGI exponential model improvement a lot of the AI bros hype up. If we continue to see improvements on the level of GPT-2 to GPT-3 to GPT-4, then the economy as we know it changes forever. I've already seen research prototypes using LLMs to do automated reinforcement learning and optimization for robotics, so you could rapidly see automation there as well
We’ve seen browsers behave differently in subtle ways. To mitigate impact while we figured out the correct fix, we’ve served different content to them so those users still get a working experience while we figure out and fix the underlying issue.

This had nothing to do with feature detection, so the usual suggestions simply won’t work.
For me personally, the cost isn't a factor. I'd gladly buy a small Android phone for up to $2000 if it would satisfy all my needs. Yes, I'm this desperate.

And by the way, high-quality Android phones cost comparable to iPhones. Keep in mind that Apple is simply not interested in the budget segment.
This but without any irony.

Half of the companies in the Russel 2000 are unprofitable and chronically mismanaged. By contrast he magnificent 7 are effectively monopolies with good management teams that make money hand over fist.

OK, Apple and Tesla are overvalued. They're both struggling with growth. But Microsoft has a market cap of 2.8 trillion and it's still growing at 15% year over year. It's absolutely unreal. Amazon, Meta and NVIDIA are also doing great.

It's easy to yell "bubble!" and certainly it's not hard to find stocks that are overvalued. But it's nothing like yesterday's zaniness of NFTs and DAOs.
Your getting downvoted because you raise no interesting counterpoints and are just leaving unfounded conspiracies like other brain damaged folks.
I’ve got a regular RX 6600 (non-XT), and it’s been fantastic for the mostly older and/or indie games I tend to play, even at 1440p.

Eager to know how this will compare. I’d like something beefier than what I have now, but what used to buy you a whole upper-mid-range PC barely covers an upper-mid-range GPU.
Yes, you're on spot! Surely, I can try this workaround. Do you have any references for this workaround?
I can confirm that the extension system is simple and nice to work with. I implemented a thin Go library for writing Dillo plugins (https://github.com/boomlinde/dpi) and made a plugin for the Gemini protocol (https://github.com/boomlinde/gemini.filter.dpi). I believe that in recent versions of Dillo, even https is implemented as a DPI plugin.

Show HN: Developed a AI-Driven Inside Sales Coaching/Review Tool
Hello HN community!

I'm excited to introduce Manja.AI, a AI-driven sales coaching tool developed specifically for inside sales professionals. Similar to using review after you play a chess game online, this allows you to analyse your calls and demos and get coaching based on how you handled the conversation.

Free Access: Launched with a free tier, no credit card required, perfect for individual sales agents. Built Manja.AI to help salespeople realise their full potential and would love to get feedback from the HN community, especially:

User Experience: How intuitive and user-friendly is the interface?
Coaching Quality: Are the AI's insights and recommendations helpful and accurate?
Impact on Sales Performance: Do you notice any improvement in your sales techniques or outcomes?

They don't like heat pumps mainly because their customers "don't feel the heat" from them. The heat comes out at lower than body temperature (85F/30C) so the customers don't feel like they're really working, whereas a gas furnace or electric heater usually heats to 120F/50C. So, customer satisfaction is often lower even though they are saving money and polluting less. But, you know, that 85F is plenty to heat a room to 72F and keep you warm.
Counter point, the war on heat pumps is mostly a British problem. Everytime I have heard it come up its in context of the UK. Don't think the US has anything to do with it.

The way I see it, either AI takes off and capital becomes an even greater proportion of production than in the late 19th century, or my job stays relevant.

To hedge against the first possibility, I want to at least have some presence in the stock market. (A broad presence, not only "AI stocks"). If the current AI boom is a bubble, I will stay employed for another couple of decades, and don't need those savings yet.
I like how he uses iso8601 dates even in conversational writing. I thought it was just me.

There are 2 limiting factors taken into account during design - regulations and peak current that the battery can supply.

The battery thing (usually a coin cell CR2032 that can supply ~13mA per spec) can be a bit mitigated with a beefy capacitor (though RF packet length and space in-between have to be appropriate for the capacitor recovery, not to brown out the system).

Usually the bigger bottleneck is the regulation, so you tune for best performance in a clean environment. Hand and body during operation are really unpredictable to model in/retune, but luckily usually adds for the better.
Anyways the range of the classical RF fobs (@3xx-4xx MHz and 8xx-9xx MHZ bands) is well beyond the real world needs that the 10-20% drop of performance due to certain fob positions will make a difference. If it does, you probably have a low battery.

Next gen fobs (if they hit the mass market) are BLE and there the range performance is more critical. Dunno what will be the approach there.

What can cause problems are ornament and the mechanical key insert. It has to be extensively tested that there is no coupling with those metal parts that are close to the antenna. Problem comes sometimes when they decide to redesign a bit the keyfob without going through the tests internally (e.g. oh it's just a minor tweak of the radius of the metal ring around the fob housing...) and then the certification fails and has to be repeated (not just money, but getting the slot for it...).
Some OEM might even be inclined to think they don't need a certification for such a minor change and push it to the market, making the problem worse if there is an issue.

Regarding the ornament things on fobs, there were even instances of them magnetically coupling with the wireless chargers or even immobilizers and that lead to some melting...
I can't imagine that a traditional furnace and AC could be less efficient than a heat pump, unless you almost never turn your heat on—a heat pump is many times more efficient, in terms of energy consumption, than a traditional furnace.

That said, if it's rare to run your heating then a standard AC unit is probably marginally more efficient than a heat pump for just the cooling operation

This means, that a lot of python libraries like polars or tensorflow are written not in python.

So python programs, that already spend most of its cpu time running these libraries code, won't see much of an impact.

Maybe, at that point it is basically similar to the struct-of-arrays vs array-of-structs trade-off, except with significantly worse ergonomics and less pay-off.

The issue is that intelligence itself is an ill-defined concept, and an unofficial but broadly-shared rough definition is "what separates humans (and some animals) from unanimated things". So, as soon as a machine can do something (whether it's having good memory, proving things, playing chess, translating texts, drawing a picture, driving a car, anything) it no longer belongs to "intelligence". Using that very definition, AI is an oxymoron.
Wouldn’t a shift to data science require more R people, not fewer?

I worry that they’re struggling so the “data science” bit is just marketing scrambling to reposition the good stuff it already does.
Maybe the IT recession is also related to the low hanging fruit having been picked. See the "IT employment grew by just 700 jobs in 2023" thread: https://news.ycombinator.com/item?id=38912125

No point hiring 20,000 people and having them work 10+ hours per day including weekends to do what? The Metaverse that noone asked and noone uses? And there's only so many social platforms specialized on people with curly hair one can make.

I know every generation said "this time this is is, there's not much to be invented anymore" but if we add "with little effort" (i.e. reaching for the low-hanging fruit), we might actually be it.
I can exactly imagine how it would happen in a large company:

1. It's a boiling frog problem which developed over several years. It started fast when the JSON file was small but then got a little bit slower each time new content is added.

2. It's also not exactly an "interesting" part of the code base. IIRC it's a JSON file which configures the ingame shop(?). This was probably delegated to a summer intern to implement in a couple of days, maybe in an entirely different department from the people who develop the actual core game.

3. New shop items are probably added by a content team without programmers in the loop who would know by instinct that something must be wrong. People on that content team also most likely don't stay on that team for very long, which together with the boiling frog problem above means that everybody thinks "it's always been like that".

4. Any specific feedback from the outside probably gets lost in the noise of other requests.

5. ...plus a general 'not my problem' attitude common in big organizations and an always-full kanban board ;)
Why Shrinkflation Works So Well (and When It Doesn't)
> This bugtracker is a work place, not a discussion forum.

that's actually an excellent way to frame what a bugtracker is actually for.

it is about workers getting shit done and its optimized for the people who work the issues.

it isn't optimized for the people posting comments on issues.

and the fact that a lot of users that have never had to deal with fixing software bugs think it looks like a forum website would explain the impedance mismatch that you often see.
1). Not actionable or even well defined
2). Not actionable, doesn't appreciate that questionable people won't present themselves as questionable in all cases or be easily detectable
3). Same thing
Oh come on. As soon as any issue hits any "social media" site, the comments turn to shit with people inserting their own clever meme or whatever.

The bug is well understood, there's nothing to gain from keeping the issue open and a lot to lose. Getting notifications for "shit posts" is pretty annoying.

_Maybe_ they could have avoided explicitly calling out HN and just said "social media" or whatever. But you're really pulling at straws to get offended here. I don't think their an asshole, I think they're pragmatic.
A jet airplane is low-drag and has thrust from its engines; a phone has neither. The phone’s downward velocity is constantly accelerated of gravity, so it will stay at terminal velocity downward. Its forward velocity begins rapidly decreasing immediately upon leaving the plane, due to air resistance. After just a few seconds, the phone will be traveling mostly-downward.
