I am not against hydrogen, but seems to me as if nobody in the space is noticing the disruption what electrical batteries already are. If battery trends continue by 2030 the value of refitting infrastructure to hydrogen easily becomes questionable [note], when there's a way to both transport and store energy more efficiently and at the same price if not cheaper. There are no signs of battery improvements to stop anytime soon or price to stop dropping.

[note] for pure hydrogen eventually everything except the pipelines will have to be replaced

Tesla said that they will use LFP batteries from now on in all "standard range" cars.

https://www.cnbc.com/2021/10/20/tesla-switching-to-lfp-batte...

As I understand it, the "standard range" cars are no different from the long range cars, other than a software flag that allows a greater battery discharge.

So this will complicate the Tesla fast battery swap stations if they ever actually build any of those.

It's the other way around. WebApps at the time would have been a complete joke since mobile browsers were so limited. At least that's how I understand it. He just didn't want any third party apps. He wanted to make every app in-house. (For example the original YouTube app was an in-house project.)

It sounds crazy but at the time the wild west of apps on the desktop meant that the user experience was pretty poor and allowed malware to explode.

It has been said that Microsoft's failure to fix these issues is really what drove web application development. No one realized a viable alternative was to lock down the device to a single store/publisher and then take a 30% cut.

Now that WebApps probably could replace nearly all native apps, it's in Apple's best interest to not fully support PWAs, WASM, etc. because the app store is so lucrative.

No, parent comment isn't false, even if the wording could be more precise. It is true that M1 CPUs do not execute x86 instructions, but the machines do, in effect, execute x86 binaries. Also, M1 does have added instructions for TSO to improve performance of translated code.
With TimescaleDB compression, 1000 rows of uncompressed data are compressed into column segments, moved to external TOAST pages, and then pointers to these column segments are stored in the table's "row" (along with other statistics, including some common aggregates).

So while the query processor might still be "row-by-row", each "row" it processes actually corresponds to a column segment for which parallelization/vectorization is possible. And because these column segments are TOASTed, the row itself are just pointers, and you only need to read in those compressed column segments that you are actually SELECTing.

Anyway, might have known this, just wanted to clarify. Thanks for discussion!

Variety is good for evolution, so I guess having only ideas being fit when they are close to a majority cultural aspiration would actually limit the applicability of the gene-meme analogy in this context.

I am actually afraid that the error correction mechanism is this oligoculture we witness which to me indicates that memevolution is short lived and will have to evolve itself. Wondering whether oligo culture and the move of Overton windows is for memeevolution to use physical survival in the context of conflicts as a means to error correct.
Well. In such situations, I turn to HN. Now what does that say about me?
You can do third party verification without storing the physical credentials. Parler was many things, and poorly designed was one of them.
It's really hard to come up with a sane reason why you would ever implement a PAKE with a browser HTTPS application. Probably the best-known use of any PAKE is in Magic Wormhole, where the PAKE passphrase (auto-generated) is a fundamental part of the trust model, and the application itself never touches a browser.

It's a problem with PAKEs that they're kind of neat to think about and play with, so people look for things to stick them onto. They're usually not the answer, which is why you don't see them used all that often, and why they're used almost exclusively in custom protocol settings.

(It doesn't help PAKE adoption that most custom protocols are better served by standard authenticated key exchanges based on real cryptographic secrets, rather than passphrases).
Listen, I know we're all senior developers working at a FAANG, making between $300k-500k/year in total compensation, but $160k/yr is a giant pile of money for many, many Americans. The fact that it's $160k + health insurance plan that qualifies as "really fucking good" makes that $160k far more than the already-above-average Joe's 160k.
That's awesome! Good luck! :D

> I shudder to think how much of the world economy would grind to a halt if Amazon or another significant cloud provider had a sustained, multi-region outage (say 24-48 hours).

Amazon and Microsoft cannot afford to go to these lengths for the market they serve.
"The worlds smartest man means no more to me than the worlds smartest ant". Dr Manhattan

I am not the smartest person in the room nor the least. But I know my smartness / IQ lies on a spectrum - just like my tolerance for cold or for oxygen etc.

It's pretty easy to find places where my tolerance for cold is utterly exhausted, and there are situations where the same is for my IQ. And it's fairly easy to find animals or other organisms who can easily handle temperatures I cannot.

I suspect in the big universe there are plenty of creatures whose intelligence and smartness extends out past the spectrum on which I, pg or Einstein sit.

I would like to know the answers they have to these questions - and I wonder if I would ever understand them.

One day we might meet such a species. Will we be happy as the pet?
Dunno, I think I’d rather wait in blissful silence.
> So this will complicate the Tesla fast battery swap stations if they ever actually build any of those.

I don’t think they’ll ever build those. Huge infrastructure requirement, gigantic overhead, most people don’t take long-distance trips often and when they do a 20 minute supercharge is good enough for people to not really demand a battery swap station.

You also can expand the footprint of “cords” much faster and much farther. Not to mention battery swap stations probably wouldn’t be designed to service other cars, unlike future charging stalls.

Interestingly, and only slightly related, Apple seems to be expanding the number of devices that it's on.

There was an apple.com web site recently that stated that either Apple Music or AppleTV was available on game consoles. Naturally, as soon as someone noticed and made it public, it was pulled. But it's interesting to see how readily the big content producers are willing to add and remove themselves from people's boxes.
It’s better used as an app on these devices. A webpage would be very cumbersome to use with a basic remote and lower powered processor. I also assume they integrated into search and other roku functionality.
This is actually pretty cool. Most network configuration tools I know (eg netplan) do not go down to the level of 'clusters'(eg defining how multiple vms would talk to each other in one file) and don't even cover namespaces.
I have a similar (hack) at work to configure physical clusters. Would consider switching to something like this mechanism if you supported specifying physical nics. Mine is nowhere as clean as yours.

Main thing that's missing specifying 'machines', nics by mac, irq_assignment of nics(auto, vs cpu-ranges or numa names)
Tesla has no plans to develop battery swap stations. They abandoned them back in 2015 or so.

Standard range cars have fewer cells than long range cars, so it's not just software, they physically output less power.
If I was, I picked the wrong topic. Far more likely to start a punch-up here by mentioning affirmative action, US partisan politics or Rust.
Could you quote a specific sentence that supports any of your claims here?

> I grew up thinking that being smart was the thing most to be desired. Perhaps you did too. But I bet it's not what you really want. Imagine you had a choice between being really smart but discovering nothing new, and being less smart but discovering lots of new ideas. Surely you'd take the latter. I would.

This seems like the closest thing. But it's perfectly fine to mention one's own childhood experiences.

You might want to read http://paulgraham.com/disagree.html, since it sounds like you don't actually disagree with him on anything. Which is to say, your reply is a DH2 at best.

"So this will complicate the Tesla fast battery swap stations if they ever actually build any of those."

They aren't planning do battery swapping. None of their recent designs have any provisions for it. That was something they considered early on and then abandon once they advanced their fast charging technology.
Twitter gives you engagement, interaction and feedback in a way blog posts don't. I still dream of someday figuring out how to get such engagement. I feel like I'm suffocating and it's hurting my writing. I need engagement to know what to write about and I'm not really getting the kind of engagement I need.

If you are socially plugged in at work or something and somehow magically know what the pulse of some segment of society is, good for you. Different strokes for different folks.

For some people, Twitter is how they take that pulse. Why rain on their parade?

Not clear that’s the case. BEV will become more common as production ramps up. Unit costs will come down. No way BEV are the dominant form of transportation at a sales price >$40k.
A side benefit of burning the petroleum is trees do grow much faster and bigger.

Somehow there is a synergy here we haven’t quite accessed.

Burn petroleum => release CO2 => tree grows, sequesters CO2 => use tree for something that doesn’t burn it or compost it …

I feel like we are on the edge of figuring this out.

I really, really like The Art of Programming Embedded Systems but I think that (1) it's out of print now and (2) it has some dated advice (that was excellent at the time) that can send a modern programmer down the wrong path. OTOH, Jack has a mailing list: http://www.ganssle.com/tem/tem432.html that is current and very informational.

I agree that Arduino is not a good start if you intend to become a professional. Arduino works really well for the non-technical person who will never progress beyond the arduino ecosystem, and for the experienced embedded programmer who is well aware of its limitations. Beyond that, if your intent is to learn embedded systems professionally, pick up an ST Discovery development system (about $20 IIRC) and have at it. Although I worked for a company that standardized its embedded development on Nordic processors, I don't recommend them unless you need wireless in your project.
I wonder to what degree anybody's mind changed in that subreddit, as opposed to the individuals being replaced with others of different beliefs. That's always a question when people attribute a collective with beliefs and other similar characteristics. The 'collective' is an ever-shifting amalgamation of different individuals.

This is why I look for sales training in my hires. Its clear that the Apple rep was asking probing questions trying to wrestle him into a decision funnel. I've sold laptops to a bunch of grandmas who've given me questions like that, and never to a "CPU designer".

It's interesting how a comment can be so differently interpreted depending on what you extrapolate from the term 'collapse'. It might conjur up preppers spouting about TEOTWAWKI, WROL, and SHTF as they lock down in their bunkers waiting for the bombs to drop. On that basis I understand your response.

But there is also much discussion on peak oil and climate change that apply 'collapse' differently, as shorthand for a simplifying of the economy and civilisation as a result of no longer having the cheap abundant energy needed to sustain the level of complexity which it has grown into during the age of fossil fuel extraction.

If (and it's a big if) you anticipate the fossil fuel boom ending without the advent of an equal or greater replacement energy source, collapse by the latter definition is a useful term to discuss what that might look like. It's certainly true that we have extensive supply chains, dense living, abstraction from the fundamentals of survival, and many aspects of our current way of living exclusively dependent on fossil fuel and petrochemicals. So it follow that without equivalent or better energy source to sustain those things there must come about, either by choice or circumstance, a simplification (or collapse) of many aspects of present-day civilisation.
I would really like them to elaborate on exactly how these changes reduced their revenue by a couple of houndred million.

To be fair to apple, the global supply chain interruptions and labor shortages reduces the "short-term appetite to generate additional customer demand through advertising." which loosely translates to companies had empty shelves so didnt bother paying for ads to drive customers to their sites for stuff that isnt in stock
Depends on what part of the game you’re working on, I imagine. Building a game (or any software product) is probably more like building a house. You need architects and designers and painters and carpenters and masons and electricians and plumbers. If you do frontend stuff you’re more like a mason or carpenter. Backend more like electrician and plumbing. Systems design -> architect. Interaction/UX design -> designer.
"Acceptable" is a stretch. There is no way of discovery, say via the App Store. There is no "Add to Home Screen" button (apps can only tell users to open safari settings and do it themselves).

If some government wants to control what you say online, they will make sure you do not have any anonymity at all, like China does with Uigurs by forcing them to use devices with pre-installed tracking software. Many countries do not have technical capabilities to do so, but this also means that main beneficiaries of anonymity there are radical political and criminal groups rather than ordinary people, which may not even have good access to the Internet.

Dan's posts are usually a pretty good mix of engineering, analysis, and engineering org dynamics. I think his diagnosis is correct that a lot of junior engineers prioritize avoiding looking dumb than coming out of a meeting knowing more than you started.

In this case, the post leans more heavily on personal anecdotes than survey data, so I can see why people are finding it a bit grating. And that mcguffin about laptop boxes isn't helping =)

That's an article about toilet paper usage, not building material. There's no petroleum toilet paper, by the way.

Wood is biodegradable, renewable, and recyclable. It can be grown and harvested sustainably; I know because I used to work with a guy who made a living off surveying forestry for sustainable timber harvesting.

It causes no environmental issues if left to rot, doesn't have to be disposed of in a particular way.

The vast majority (well over 90%) of plastic is not recycled.

Plastic never goes away. Plastic just breaks down into microparticles that are now so pervasive there's basically no part of the planet that doesn't have microplastics, no animal that doesn't have them in its digestive system. And all the while, it's leeching out toxic chemicals.

Brace yourself for the op-eds about "learning to live with less" and shaming people about their consumption / prosperity.

You're correct. In fact, as I type this reply my cloudflare diagnostics are indicating I am talking to a datacenter 200 miles further away than would otherwise be ideal. That said, its still within an extremely reasonable distance. This is a "risk" I am willing to take. It's certainly a better starting point than guaranteed 70ms minimums.

You could use Nuclear energy to extract oil. If you really need oil that could make a lot of sense. For example if you need it for chemical processes or as fuel.

The EROI is only a limiting factor if you look at all your energy sources combined. For example, Saudia Arabia (or rather Canada with their oil sands) could invest in Solar and Nuclear to keep extracting and exporting oil even though the EROI of the oil wells themselves fall below unity.

Maybe this is the root of the problem. Should you need that deep knowledge in order to be proficient? I mean, the point of so many libraries and frameworks was to remove the need for a deep understanding of the underlying technology.

Perhaps the need to understand it deeply indicates that they've largely failed?
