I checked your numbers, and you are right.

The Hindenburg had a total mass of about 240 tons. In its last voyage it burned 42 tons of fuel over 77 hours. It was an unusually long voyage due to high winds, but presumably the engineers who built it took these type of conditions into account, so the takeoff fuel was probably 50 tons or so.

A modern airplane of the same size (mass) is A-330. It has a (fully loaded takoff) mass of 240 tons, and a takeoff fuel mass of about 110 tons, so more than double the Hindenburg's.

Hindenburg's speed was about 125 km/h, while A-330's speed is about 1000 km/h, so about 8 times faster. Indeed, a Frankfurt-New York flight takes about 8-9 hours in an Airbus, it used to take about 60 to 70 hours in a Hindenburg.

Of course, if it takes you 2 days to cross the Atlantic, you need a bed. So, Hindenburg was able to accommodate only about 70 passengers, while an A-330 can easily fly 250.

Finally, regarding solar power. Hindenburg's area as seen from above was about 10000 m2. Current solar panels can produce up to 220 w/m2, so if we cover a Hindenburg with such panels we'd get 2.2 MW peak power, or about 3000 horse-power. Hindenburg's engines were producing about 3300 HP in cruise mode. Today, with better propellers and CFD modeling, you may not need more than 3000 HP to get the same thrust, so at peak solar radiance (noon), you would not need to burn any gas at all. Of course, during the night, the solar panels' output will be zero, but the modern engines may be more efficient, so all in all it's likely that instead of 50 tons you may only need 25 tons.

I've gotten more sympathetic to this over time. A few years ago I lived in a young (and constantly under construction) neighborhood. after weeks hearing jack hammers and other construction noise, it starts to get old. especially if you work night shift and try to sleep in the morning...

If it ever stopped that would be one thing, but it never does. It just moves around a bit but never stops. The noise, the bad traffic, the unpredictability, the random power outages, etc start to get really old and for the several years we lived there, it was never "done." Maybe I'm just old now, but I really understand the appeal of an established and static neighborhood that doesn't change.

> If your best hire is somebody you had less confidence in, then it's a sign your confidence function is not fully tuned to what's causal to success.

I think it's unreasonable to think that you can guess so well as to how performance will be over 6 months-1 year+ periods in several hours of measurement.

> If your average tenure is < 2 years, there's something wrong

My average tenure was much higher than that. But again, about 1 in 6 didn't make it a year. Turnover rate past that year was very low.

I'm not sure why you think having 15-20% of people not working out in the first year (after which turnover drops) translates to an average tenure of less than 2 years. It implies one greater than 5 years.

> If your best hire is somebody you had less confidence in, then it's a sign your confidence function is not fully tuned to what's causal to success.

If I had a fully tuned confidence function, it would output 1.0 for candidates that would work out and 0.0 for candidates that wouldn't. This isn't realistic.

Nor is it realistic for it to monotonically increase with candidate quality (in which case it could be transformed to the above function with a threshold).

> Finally, it's pretty bad for company culture and morale to have a high fire rate.

I don't think getting up to 1 in 6 (first year) freaks people out too bad. Rates across a broad variety of industries and employers are more than 1 in 3 quitting or being fired in the first 18 mos. I think one can do significantly better than this, but I also think 1 in 10 isn't attainable and question your numbers.

There is indeed a way for technical users to troubleshoot battery usage, although this does not necessarily help even technical users when the app turns out to be important.

iOS tends to make it significantly harder for applications to justify background processing, so I myself tend to find battery statistics less useful - you have apps which have a more voracious appetite than others, but typically only when you are actively gaining value from them.

My feeling (I'm not an American) is that America got attacked and partly lost its mind and partly just had to lash out at somebody in retaliation to keep up its deterrence as a superpower. That climate made the Iraq invasion look like a good idea at the time.

As far as I understood it, 9/11 was never stated as an excuse to invade Iraq (as opposed to Afghanistan). At best as a reason to take the region more seriously. The government was convinced Saddam Hussein had connections to terrorism, but that wasn't really the reason to knock him out, they thought he had weapons of mass destruction. And yes, the Bush administration really was convinced of that, they just lied about the degree of evidence they had.

Going through the sample chapters and within 30 seconds finding myself chuckling at the beginner mistakes the book is pointing out not to make, for example presenting labels and values where values on their own would be sufficient [1]. And further down on the same page 'Combining labels and values' (I would almost always make the mistake of not combining them) - seeing the wrong and right ways side by side makes it obvious, even to me.

A huge amount of NIMBYism (although certainly not all) is about what other people can do with property they already own, or what the gov't can do with property it owns.

The GP groups eminent domain in with NIMBYism, you are grouping NIMBYism in with eminent domain. Oversimplification dilutes the conversation in the same way that substituting terms does.

His example of building a protected bike lane on a city road does not require eminent domain and in my opinion requires far less scrutiny than project where a person's property is considerably affected (as far as I'm aware most people interpret the backyard in NIMBY in the metaphorical sense rather than the literal one). I would assume that the GP feels similarly given the type of projects they want to see completed. They seem primarily concerned with local projects which usually don't need eminent domain because they have a decent level of flexibility in their location, unlike highways or train tracks.

This is based off of the people I've actually met.

I'm not meeting people who are living with their parents so they can save up enough money to buy a house.

Again, this is just based off of my experiences. One of my own uncles never moved out or did anything with his life, unfortunately there's just a lot of people like this.

I have had a very unique life, and according to the lessons I've learned I'm extremely selective of who I'm around. If you're in your late 20s or 30s and you live with your parents, I'm going to have major doubts about your maturity. This is fine, not everyone is going to be attractive to me, and vice versa.

The biggest issue is when you deal with someone who's used to having mommy and daddy take care of them, they'll want someone new to take care of them. I've known guys like this, I've known girls like this.
> Are you asking this genuinely to find some items that Webkit doesn't implement

I’m trying to find standard items that WebKit doesn’t implement. Comment chains usually devolve like so:

X: “Safari doesn’t implement Z feature I like and chrome does”

Y: “Z feature is not a web standard but a chrome pushed feature”

Conversation ends and then repeats on another thread. Over and over and over again. Chrome-backed features muddy the discussion we should actually be having: What standards does WebKit not implement and why

Since caniuse lacks the labeling of what stages an API are in , it’s a misleading answer to a very specific question. A better answer would be a link to MDN web docs that does show if a feature is experimental and shows browse capability (all though not to the extent that caniuse can)

> or are you coming in with the conclusion already that WebKit implements everything

No. It doesn’t make sense to make a thread actively searching for standards not implemented. I could’ve just not if I believe foolishly that Safari implements everything.

> if you really want to learn what features safari may not have, why not actually go down cyanydeez's post and eliminate each as not real standards

More so than wanting to see what feature safari may not have, I believe HackerNews will benefit from an outright guided discussion. Could I do it? Sure I’m hell right tempted to take caniuse & MDN web Docs data and export them out as a categorizable & filterable table of standard, experimental, and exclusive API’s but I believe this approach is far more engaging. It is something I’m actively experimenting in my head about how to go about it.

> It's a massive chore to have a teammate that causes stuff like this and I don't envy your teammates or lead (even worse if you're the lead, obviously).

It gets tricky. I haven't had to deal with this friction for many years, but it's not because I entirely avoid the type of directness described in OP's last two examples. It's because I'm careful about who I'm direct with, and because I've ended up in environments that are increasingly devoid of the emotionally-fragile.

I start out with a baseline of assuming that people are as fragile and childish as what your comment alludes to. In many companies, I'm sure this is actually the case. But as I get to know a coworker, it's very often the case that they have the talent, maturity, and emotional stability to handle direct communication (in both directions) without spiraling into an episode.

In my early career, I joined a company with an awful hiring pipeline as the first employee. That was my first introduction to the idea that a lot of people react violently to being treated with respect if they think they don't deserve it. I quickly started treating them like children as you suggest, and the problem immediately vanished.

But as I've progressed in my career, the amount of time I spend around mediocrities has plummeted, and my prior that the person I'm communicating with is a mental adult has risen. I've found that high-productivity professional contexts weed out the emotionally-unstable in the same way they weed out (eg) the disorganized; the value of good-faith efficient communication without mental breakdowns is simply too high.
In what context did they reveal the existence of their recordings to you? Was it a gotcha situation, or something like the two of you were having a hard time remembering something, and they said they would just check their logs.
Much more often than they choose to do so on iOS.
It’s easy to forget that a central job of the Embassy was to support Saudis going to school and they had been providing this service formally and informally for many years and to many people -- the vast majority of whom went back to their community with an expanded outlook on life influenced by the tolerance and social freedoms of spending some formative years in the west. If the Embassy didn't know these guys were terrorists (due to the for-eyes-only information stovepipes which affected the FBI just as much) then they would treat them just the same as any Saudi in the USA -- on-board them into the US (advice on accommodation/where the mosques are/where they serve hallal food/introduce to other Arabs in the community/play cards/etc), then check up on their situation from time to time. And then try to hide the fact they had any contact at all after the passports turned up in the wreckage.

Not saying it’s impossible for any specific bad actor collusion by some individual(s)/institution(s) with overlapping goals - just that proof there was Embassy contact and some support for these terrorists is not conclusive evidence because the same could be said for several hundred thousand non-terrorists.
My experiences with ROS have mostly been klunky. The documentation is really sub par, the Python portions completely highjack the logging module, and (if my memory serves me) the messages types aren't backwards compatible like other IDLs and so it can be a maintenance nightmare. I also felt like it was too easy to outgrow, like when wanting to communicate using something other than ROS messages, or upgrading the codebase to a C++ version that ROS noetic doesn't support.

It's a hard battle against status quo and bureaucratic institutions but I still think it's possible to reduce that by a lot. I'm willing to bet that a lot of those people are below basic because they weren't given chance to succeed due to child poverty, schools playing numbers game[1] and various other factors. We don't even have to add new curriculums. Just by getting the "basics" right, we can lift those numbers up.

> Having lived in cities with rent control, what I've observed is people who get into a rent-controlled apartment simply NEVER leave it.

Yes, because they're rare, and the only way to not be uprooted. How are you posing this as a bad thing? If there were more rent control, then this wouldn't be a problem. Why should rent get to rise so drastically above inflation? The core reason it does today is because people are buying them endlessly as investments, and as the property exchanges hands at completely arbitrary values, the new owners have to raise rents.
Yeah in practice the Rust community writes a lot of code that uses experimental features, that need an explicit feature gate and the nightly build of the compiler. This is less common now, but it was huge during earlier development; a lot of the async work only ran on nightly compilers.

If the Rust team refuses to ship the features in stable releases, people are just going to use unstable releases and that will make the experience worse for everyone.

There is no way to artificially restrict features unless you have multiple software in the ecosystem that needs time to update: for C it is the other compilers following the C standard, for Python it is the Python executable on your end- user's machine. The minute rustc updates, Rust developers have little reason not to use the features.
Anyone with a modicum of awareness of politics at the time knew the Bush administration:

1) wanted to be in a war, since it historically makes the administration more significant

2) wanted to invade Iraq to "finish Dad's business" (and show him up)

3) oil

4) military industrial complex loves war

Sadly, #3 is the most sane reason we got in that war.

Oh yeah, and Halliburton made a mint on Iraq war support. The corruption was that blatant.
i had some more crackpot thoughts if you don't mind hearing them lol

the set of all strings is countably infinite like the natural numbers

however human language when actually spoken can contain recursive implicit meanings and subtext, so maybe even though it's just strings, if you made the implicit context explicit it would be uncountably infinite, much like the real numbers, even though in practice the meaning a human can grok from any given sentence is bounded like a ieee floating point number.

but i find it somewhat interesting that whereas all ieee floats have a certain amount of meaning they can carry around/a set amount of decimal places, the way we encode implicit meanings and tones into language is uneven, it's not character by character (but it can be if you add an accent or tone to a character even in non tonal languages),

like, what if you could design a number system more like human language where the decimal places somehow only showed up under certain conditions (maybe you could argue complex numbers are kinda like that, since the imaginary or real parts will appear and re apper under certain operations)

could you design a number system or an algebra in such a way that it was up for interpretation lol (or if not why not)

one thing is that you can interpret numbers in terms of geometry, but the interpretation is one to one, and thus boring compared to the interpretability of strings.

also maybe lambda calculus is somewhat interpretable in this way, and it can encode numbers and algebraic rules

maybe logical conclusion of this train of thought is the IO monad XD
> Obviously if the Saudi had been there involved in 9/11 directly or indirectly they would have been a invaded the next day

9/11 happened because al-Qaeda said the US had already had invaded "Saudi" Arabia eleven years earlier. 9/11 was successful in that it was the catalyst for removing US military bases from Saudi Arabia within two years of 9/11.
> major gun control

This comment (and often the "correlation != causation" discussion more generally) seems to equate "causation" with "proof of causation" (in a mathematical sense), which is a flawed criteria for science IMO. The causation part (not the mere association) is the substance, so it's appropriate to use causal language.

Of course any such explanation is provisional. I might think your comment is just to complain the provisional aspect isn't mentioned in the quote (I think it'd be tiresome to say that in every statement, and the public's understanding of science being provisional is underestimated), but you seem to think it's a problem that causal language is used at all?

While quote may have been offhand, look at what the actual paper says [1]: "[the study] design prevent[s] strong conclusions regarding causation." Note that it doesn't say it prevents any conclusions regarding causation.

By the way, it seems weird that you yourself have come to believe it's causal, while seemingly denying that this paper provides any basis. How did you come to that conclusion then?

Remapping bad sectors to the end of the drive doesn't solve much. For starters, GPT actually expects the end of the drive to be usable, so we'd need to introduce a new partition table format or make the drive an active participant in updating the partition table.

But more importantly, you cannot simply hand-wave away the challenges of having NAND erase blocks that are huge compared to both NAND page sizes and the allocation units used by host software. If you make a drive that is at first glance "compatible" with existing software and filesystems but behind the scenes has to do eg. 24MB read-modify-write cycles for any size of host write, the drive may be much simpler than current SSDs but will be dead within a week or two at most (and painfully slow until then).
> An alternative to sealing is embedding the whole object in a substance whose surface forms a mosaic that is difficult to reproduce and changes when manipulated.

The problem with a QR code is the “difficult to reproduce” part —- if you can organize the rice in such a way that it’s recognized as a valid QR code, surely the attacker can recreate the same QR code (or an equivalent, since QR codes have redundancy/ECC).
