When solar and wind and sodium ion batteries are basically there and probably don't need as much investment and R&D (or it's happening anyway from 1000 existing funding sources), it's probably bad. Or at least unlikely to happen.

SMRs can potentially do something that renewables can’t: they could be placed near the loads in places with no space for renewables and without relying on the grid. Think industrial areas or even cities or towns that are surrounded by other developed land. The grid moves slowly, and electricity prices via existing transmission lines are, in many areas, hilariously inflated for a number of reasons. A hypothetical portable, easy-to-acquire SMR producing power at $100/MWh would not be an amazing deal if a large electric utility bought it, but a $100/MWh would be an amazing price in quite a few markets if a small utility could actually buy at that price and deliver via a small last-mile distribution system.

I am a bit more comfortable saying "Biological systems also have 'solutions' that emerged through evolution." That is certainly true. But unlike designers, evolution is perfectly happy to re-invent the wheel (even if it is a less functional wheel). So different, evolutionarily independent, processes may provide the same solution, and of course solutions are constantly re-used to provide slightly different solutions. So I'm not sure that "complexity" is the hardest problem, though it certainly doesn't make things easy. The diversity of solutions for the same problem makes generalization/abstraction even more difficult.

Why are you comparing the rate of change of battery storage capacity, the vast majority of which if grid connected will be used for at most diurnal storage, to yearly energy consumption?

Holy mother of all type errors there.

Multiply it by 365, and it implies that in 2030 alone, we will create enough battery storage to time shift almost 10% of our total electricity use today.

This is not a stat that should inspire pessimism.
Let me give you two anecdotes.

(1) Some time ago I'm at a coding interview and I'm tasked with an algorithm to calculate the biggest rectangle you can make of a set of segments. Or something similar. I'm presented with a computer, with VSCode, with an open file with some code already. I left my chair, approached the whiteboard available in the room and started thinking about how to address the problem. The interviewer was not pleased with my approach and eventually after I exchange my thought process he invited me back to the computer, asked to write some code, and when he saw I was doing for loops with vars he interrupted me, pointed at the beginning of the file which was "import lodash" and showed me the expected solution. A lot of functional mambo jumbo which was obviously very sexy at that time.

I looked at his code and asked him what's the computional complexity of his solution. He looked at the code, thought for a minute and said the session is over.

(2) About that time I was doing a web app that was a huge web form. The user could exit and resume a session at any given time so the input was stored in database and was supposed to be retrieved when the session resumed.

At one point I noticed that the initial loading time was noticeably slower, and after inspection it turned out that the init time raised from zero to about 800ms. It was the same time when our senior JS programmer with 9 years of experience shipped the code that was responsible for retrival of the data from the backend.

It was functional masterpiece. No loops, lots of map and reduce and he was very proud of it.

When I pointed out it had O(N^6) complexity and could be fixed with a simple for loop matching ids he got offended and stated that "we don't program that way anymore, functional is the future".
Many distros avoid the problem with something like

apt-get install libflac7 libflac8

If you look in Fedora 40 for example, you'll find nodejs, nodejs18, and nodejs22. Gentoo's ebuilds (packages) can often have multiple major versions installed simultaneously. If I really need something, I can unpack another Gentoo userland, or use a container.

AppImages, do exist. What seems to be the missing "glue" is putting a ui in front of users to choose what software they want to run. That problem has not yet been solved gracefully.

The author says he knows how to use Linux, but observably never graduated to be a particularly advanced user.
I don’t mean to be critical, but as someone with actual diagnosed ADHD it is kinda annoying. When I got diagnosed I did my research online about what to expect, and it was frustrating (and confusing) just how many blogs were talking about symptoms I could not relate with at all. Eventually I figured out these people were discussing coping with depression, and it was disheartening that they probably are still not treating their underlying illness appropriately.
Thanks! I understand now.
>Is that no longer the web?

I don't think so

Outside of HN and a few niche subreddits, I can't think of many. Most good communities I'm part of are off the web on things like Discord which isn't addressable by search engines.
ADHD isn’t diagnosable at age two… Oppositional Defiant Syndrome is something else.
Exactly. The large majority of Americans do NOT want to live in walkable cities or towns; they love using cars to get everywhere, even across the street, and get angry at any suggestions that challenge their car-based lifestyle. Car crashes are simply a necessary cost to this lifestyle that most Americans prefer.
I guess my point here is that being closed is directly against the goals of the technology. Apple's lock-in is either a side effect or potentially even beneficial to their goal of providing a good phone/computer/whatever, whereas commercial lock-in is fairly clearly opposed to creating an API ecosystem that is usable across a range of technologies/consumers/etc.

Agreed. I order more from Walmart than Amazon these days. Gets here faster, sometimes same day, and usually cheaper.

I think they'd be further ahead if not for their branding and lack of advertising. Walmart, at least in my life experience, is equated with low class, cheap, junky. IMO they should've kept the Jet brand as their web/delivery presence.
Not sure if that is sarcastic or not, but the whole article seems to be "middle manager doesn't like basic parts of being a middle manager".
I can imagine it being a lot harder. There are all sorts of arrangements that either enable or reinforce the types/volume of food that you eat. Still, I think people should try to be aware of their own situation and try to identify those factors that promote weight gain. Even if it was harder, I still think it's inappropriate to say it's "basically impossible" and to deny common sense.
I'm not sure I follow, do you have an example where merging makes things more obvious?

The name gosub reminds me of the BASIC command, and at first I was expecting it to be written in FreeBASIC or some other BASIC dialect.
Right now, I think only three things have been assembled from multiple launches like you are proposing: Mir, ISS, and Tiangong. All of which were super expensive and the result of years of careful design work. Definitely not the way to make something cheap!

There was some talk about using ISS as a base for on-orbit assembly but the orbit (half-way between best orbit from KSC and Baikonur) isn't great for that and it turns out that constant docking and un-docking ruins scientific experiments requiring microgravity, so ISS really isn't a great base for assembly. Ideally, if you want to start on orbit assembly you'd have another station in the right orbit for KSC which isn't doing any microgravity research, but now we're talking about massive up front investment to save money on research satellites, is NASA ever going to get the scale of research budget for that savings to be worth it?

If something like Space Based Solar Power ever become a thing then such an on orbit assembly station would make sense, but the case for assembly for science missions really only closes if you have the station already for something else.
Why stop at a $500 device?

I think it should also have NVMe and SFF-8644 for external disk shelves. At least 6x 10GbE, with 4 on SFPs and 2 on copper. A GPU with excellent hardware transcoding, and slotted VRAM for that local LLM fun. Plus an 8k projector for movie nights at the office.

And a pony; every single one of these fucking kitchen timers must also come with a pony.
The word "accurate" was the wrong choice of words. The machine itself is always going to be "accurate" if it's working correctly, and cuff is used right. Perhaps "proper" was a better word, since we're not talking about the accuracy of a measurement.

Since you'll get a higher readout after exercise, or even moderate daily activities, it's recommended that the person be perfectly relaxed for a few minutes before taking the reading. What I described is just my way of being perfectly relaxed, and what I know for a fact doctors do if they suspect an actual BP problem, and want to "scrutinize" it to find the true lowest resting reading.
There’s a difference between guided selection and natural selection, guided will Greatly increase the odds of survival for the selected selection criteria, and humans have been doing it for thousands of years.

My take on this: You're absolutely allowed to speak on your experience, but you should also take the feedback at face value and try to figure out whether it's useful or not. Plenty of feedback here on HN is good, but of course there's also plenty that misses the mark.

That being said, an ADHD diagnosis at the age of 2 goes against all current best practices, so it might be good to revisit the subject and ask to be evaluated again.

Even in the likely case that it's confirmed, you might get additional support, advice or diagnoses that can help you in the future.
I mean, you can have it you’ve just got to be happy to bear the cost of rewriting the file every time you mutate a row.

That's a bad analogy. Let's change it: the man with a mortal lung wound could use the lungs from the man with the mortal heart wound, but the reverse is not true for some reason involving tissue compatibility. So if nothing is done, both men die. If the heart man is killed and his lungs harvested, the lung man will live. If the lung man is killed, both men die. So either both men die, or the lung man lives. On top of all of this, the heart man is braindead, so he has no opinion and no ability to make a decision, and no real chance at a future anyway.

I'd say it's perfectly ethical to kill the man with the mortal heart wound and take his lungs.
You raise a fair point. I think some of this is likely reactionary to some degree. Very often the response to a person struggling with a condition is "just try harder", so it's really, really easy read statements like the one you quoted as being more prescriptive than they are likely intended.
The point was about how the set of exceptions handled by `except:` might not match what the programmer expects, especially a programmer coming from a different language. It's not about knowing what kinds of exception the code in the `try` could raise and it isn't about telling a called function what to do.

Other languages, notably Java, have tried the "functions document what they can raise" idea. Everyone seems to hate the result.
very interesting project! the docs don't use the phrase "virtual machine"; i wonder if they don't consider it one, and if so, what the distinction is.
The base model isn't entering production until next year but is quoted by Car and Driver as starting at $62,985. The original price was supposed to be $39,900. However there has been >20% inflation since then, and the base model should be eligible for the full $7,500 tax credit applied as an instant rebate at purchase time, which was not available at the time of announcement.

All that to say: the price actually paid will be $55,485, vs the inflation adjusted original base model price of $48,912 (possibly higher if there is more inflation before the release next year). So yes, the price you'd actually pay has gone up 13% in real terms over the announcement price. But I think the extra 4 years of delay (for the base model vs the announced availability date of 2021) is the bigger issue.

But ultimately all that matters from Tesla's perspective is that they are selling. My understanding is that even the current top end expensive models are selling about as many units as all other electric trucks combined.
Sheet metal can be wrapped around a mold (round, square, or other) and pressed together, though it's not common. I've got a couple diy electronics protected by "boxes" made of U-shaped steel or aluminum with holes cut for the controls. Alternatively, the technique used to create cardboard boxes also works with sheet metal, where you cut the correct shape out and fold the flaps at set locations; of the metal is thick enough you don't need flaps and it'll hold the shape on its own, and if you want to hide the seams better, use compression or notches.
If you go to an emergency room and say you've taken your BP and it's high, they'll do basically what I said. Lay you down, let you relax 10 min, and then take a reading. If the reading comes up 120/80 they'll say go home, you're fine, whatever you did to take the BP yourself was wrong. I've seen this happen to someone. That's how I know.
I don't think that's meant to be taken seriously/literally - seems like a tongue-in-cheek acronym for "GOSUB".
The tendons are as inelastic as possible. The compliance comes from direct drive motors with no gearing (or as minimal as possible).
My understanding was blau-gass was unpressurized propane, which is a little more dense than air. But I guess according to that article it's slightly less.

I'd expect that, like a lot of problems zeppelins had in the 1920s, burning hydrogen would be more feasible with modern technology.

I'd also point out that the thing that made hydrogen dangerous in those airships was that the skin was two layers. The inner skin was the gas bags, which were very fragile, and then the rigid structure and the outer skin to protect the fragile bags. This was a problem because hydrogen could accumulate and mix with air between the inner and outer skins. The outer skin also was quite flammable. Nowadays, we can make materials that are both strong enough to serve as an outer skin and impervious enough to serve as a gas bag for lifting gas, so modern airships have only one skin and nowhere for the lifting gas to mix with air inside the structure.
Air resistance matters, but is only one factor. A much more major factor that a rocket needs to overcome is just gravity - ie marginal mass considerations generally trump marginal aerodynamic considerations. Partly this is a result of engineers having much more ability to control the effects of aerodynamics through launch trajectory/profile design (since aero forces can be controlled by through controlling velocity and altitude, while gravity... much less control).

Here are some factors to consider that generally trend against just "increasing the fineness ratio".

Consider your fuel tanks. Assuming that you have liquid fuel, the static pressure at the bottom of the tank for a given fuel and gravity is purely a function of the height of the fuel column. This means that the taller your fuel tank, the stronger the tank needs to be (at the bottom) to contain it. This will tend to increase your non-payload, non-fuel mass - this is bad.

Similarly, as your rocket gets taller and taller, there is more and more structural mass sitting on top that needs to be supported - ie you need stronger structures.

When a rocket second stage is in vacuum, all of the sudden you want the largest possible nozzle you can get to get the most thrust out of your exhaust. Now having a larger diameter to work with is useful since it's now easier and simpler to have a large diameter nozzle.

Rockets exist to launch payload, which often cannot be shrunk below specific sizes and/or have difficulty being mounted in different orientation. The uh... extra phallic shape of the Falcon Heavy in this case is because the payload fairing needs to be large enough to encapsulate the payload. It's not possible (or really useful) to shrink rocket diameters much smaller than their expected payload.

For a size comparison, the Falcon Heavy's payload fairing is 5.2m in diameter. This isn't particularly a small space, but it's not particularly large either - it's basically exactly the length of a F-150 or two sheets of plywood/drywall stacked lengthwise.
IIRC it wasn't a big break from 5.7 unless you used some odd grouping or relied on its old+lossy defaults.

Though the single threaded performance fell off a cliff, tanking my CI performance.

The article said nothing about weather hazards or the fact that it’s a big fat target for a war drone to bring down.

It’s not just an easy target to hit, it’s a symbolic target.

Airships were abandoned because very large objects falling out of the sky did not appeal to the public… and too many of them fell.

Extremely severe weather brings down relatively tough aircraft, but once on the ground or in hangars they are relatively safe. Airships are flying cheesepuffs.

But that will open up the market for a "Seriously Guys, I'm Actually Really" device that can be attached on the left-hand side, and activated when you really mean it.

I see a lot of growth potential in this space.
This effort is just starting up? Flying Whales expect to have an airship in 2025 and be operational in 2028 per https://www.abc.net.au/news/2024-10-11/outback-town-launches... . Not that this is a race; better if several companies succeed.
You are carrying fuel and using oxygen from the atmosphere to combust it. When it's hot, it's a gas. By simply cooling it and recovering most of it, you are potentially left with more mass than you started off with... and Oxygen is relatively heavy.

Actual diagnosis? Did you answer “very often” to “How often do you have difficulty keeping your attention when you are doing boring or repetitive work?”

Maybe we shouldn’t be going around convincing ourselves we have a disorder we may or may not have. Blaming ADHD and hindering ourselves more.

That being said, if medication helps you thats a good thing.

This results in me trusting Tesla less.

If this was fake, how do we know the robovans were not remotely operated? They might as well be too to get the stock price up?

There is no way to know. I am really doubting Tesla now. It wouldn’t surprise me that, in order to prevent mishaps during the event, everything is remotely operated…

People will say: that’s not true. But where did Tesla clearly specify this upfront?

I saw the initial fullscreen disclaimer. But that might also apply to the robovans right?
I agree that it is not often helpful to to avoid the issue by redefining a term in a way not originally intended (though it may be justified if the original definition is predicated on an unjustifiable (and sometimes tacit) assumption.)

Furthermore, OP’s choice of putting “know” in quotes seems to suggest that author is not using the word as conventionally understood (though, of course, orthography is not an infallible guide to intent.)

IMHO, Gettier cases are useful only on that they raise the issue of what constitutes an acceptable justification for a belief to become knowledge.

Gettier clauses are specifically constructed to be about true beliefs, and so do not challenge the idea that facts are true. Instead, one option to resolve the paradox is to drop the justification requirement altogether, but that opens the question of what, if anything, we can know we know. At this point, I feel that I am just following Hume’s footsteps…
