> What's clear to me is that the FAA has no post deployment validation, hasn't tested its DR strategy, and that errors can go unseen for long periods of time.

It is possible to have all of those mitigations in place and still experience a failure like this.

Post deployment validation is only as good as the validations executed. 99% coverage still leaves the door open to failure.

A DR strategy is just that - a strategy.

A failure of this sort is not an automatic implication that those things do not exist, just that they failed in this particular case.

I would find it incredibly surprising that an organization of that complexity could have survived as long as they did without a major incident if none of those things were in place.

They’d be either incredibly lucky, or incredibly competent, and if they are the latter, they would not operate without such mitigations in place.

It seems far more believable that an organization of the FAA’s age and complexity missed something along the way.
This is not the same thing. Hacker News as a website is catered to an audience that is mostly familiar with programming. I would say it's safe to assume for any given visitor that they are probably aware of basic computing and programming terminology, but not that they would know what "NetworkX" means.

The new title is fitting (it specifies what it's a Python library now).
The US does use metric system (you can easily go and buy 2 liter bottle of Coke). What you probably mean, why the metric system is not mandated as the only one acceptable for basically everything? Why indeed.
In Colorado (where the bird flu is hitting us hard) Costco rarely has the two dozen cartons in stock.

I think Costco locally sources their egg suppliers in some capacity which would explain these regional differences.

Not really sure what you are trying to say here.

Criticizing gold and diamond mining isn't uncommon. A popular example coming to mind is the "Dirty Money" Netflix documentary series (https://www.imdb.com/title/tt11947154/). The existence of "Blood diamonds" is also a pretty commonly known fact.

Temperature should be easy. Don't try to convert it. Just know that it's based around people instead of water. Anything out of the bounds 0-100 is extreme and to be avoided. Maybe it's just so intuitive having grown up with it, but it just seems to make perfect sense that the numbers are based around how you feel in relation to heat.
if that same government is also funding wars through cats paws in other countries and oppressing their own people, you should be concerned. There are plenty of governments, especially authoritarian governments like in Iran, that I don't think should ever acquire nuclear weapons for any reason.

It's more like any dictator/autocrat who wants to stay in power by threatening the world will work on it. That isn't good for the world. Your statement is not a value judgement or even interested in first or second order effects of such a decision, so is essentially useless in evaluating whether something is good or bad.
Massachusetts recently mandated cage-free eggs, which I assume adds some cost, not sure if that's a thing elsewhere.
If said employee were actively defrauding the company and covering their tracks, they would be unable to make any fraudulent transactions or track covering in those 10 days. It's probably more like 16 days ultimately since it's probably business days, so there are 3 weekends as well. This would show up as a statistical difference in rejected transactions, contract overshoots, expense claims, something like that, I don't commit fraud.

It would also potentially expose any conspiritors, because the locked-out employee's responsibilities+communications would be forwarded to someone else for those 10 days. This wouldn't help you if the locked-out employee contacted conspirator's out-of-band to warn them however.

At least, that's the explanation. I guess the logic is that to avoid this, you would need to be making _larger_ fraudulent moves, less often. This would show up stronger against the background trade. Alternatively, simply the existence of these very obvious anti-fraud measures discourages people even if it's entirely possible they are a placebo. Similar to Lie Detectors, which only work on people who believe they work.

I think it's value for company resilience doing forced hit-by-a-bus tests on their employees on the regular is far more valuable in the long run.
Interesting read, thanks for sharing.

Adding to what was said about high quality customer feedback, a downturn will tend to more quickly expose weak product market fit. In lean times, companies are less likely to experiment with new tools or processes that don't have strong and clear value propositions. If you're targeting an emerging or growing market a downturn may be a good time to test that markets' staying power.
ChatGPT: What will the web look like if LLMs are successful?
Take Stackoverflow as an example: We've all seen how good ChatGPT is at explaining programming concepts and generating novel snippets of code replacing the need to go to stackoverflow for many questions. This is because ChatGPT benefits from the entire historical corpus of stackoverflow answers, along with information from the broader web. The incentive for Stackoverflow to exist and continuously improve is that people will visit seeking answers and click on ads / paid job postings / etc. If we are getting our answers from LLMs how does the content ecosystem survive?
You have to start with toy models before scaling up.
This is the social contagion part of the theory.

The idea is that many--especially very high profile companies--overhired, and the rest are following the leader.

Stir in media hysteria around purported recessions and you can understand why leadership might start to pull the reins.
I'm in the UK. Our gas is metered in m^3 but our energy suppliers typically bill and advertise based on the converted kWh price. My current prices for electricity and gas are 33.76p/kWh and 10.28p/kWh respectively. That's after a government price cap has been applied without it it's 49.15p/kWh and 14.00p/kWh

Based on those prices a heat pump would need to have at least an efficiency of 3.28 (3.5 uncapped) just to break even. Given that the total cost of installation is in the range of £3k-40k there really needs to be a compelling reason to retrofit an existing house.

Some of this is due to the vagaries of the UK energy markets. The outcome is that we often end up paying renewable providers of electricity based on the cost set by gas powered stations. At the moment that price has been grossly inflated due to profiteering, we're far less reliant on imported gas than mainland Europe.

I'd like to note that the price savings and break even point have probably gotten better compared to when I last checked. If we go back to much warmer, happier times - like September 2020 - I was paying 15.999p/kWh and 2.915p/kWh for electricity and gas respectively. Prior to that it was 14.150p/kWh and 2.920p/kWh. At that point I believe an air source pump resulted in a net increase in my bill and a ground source heat pump would have taken around 30 years to pay off. I should probably recalculate when things have settled down a bit.
I mean the UK still does roads/cars in MPH rather than KPH. Lots of people will still give their (body)weight/ask for (body)weight in stone and height in feet and inches, although I think that's slowly changing to KG and CM.

It's a strange one though, isn't it? I was watching an exercise/nutrition video on YouTube earlier and the presenter was saying "to work out how much protein a day you need, multiple your bodyweight in lbs by X and that will give you the protein number in grams." It seemed so bizarre to combine the systems.

Edit: Just to add - in the UK we're taught entirely in metric in school, the bits mentioned above are just hangups / how it's done.
I agree there. There's a lot an individual can do to dampen the compression waves if they leave 3 seconds instead of 2. I was being facetious with 5 seconds, but in some situations the 3 second distance is still not enough time to react. For example, when there is a stationary obstruction and the car in front obscuring it swerves instead of braking.

Additionally, there's a lot to be said about vehicles not acting like they have human drivers. This Tesla basically acted like a psychopath.

I have one car with regular cruise control and one with adaptive cruise. I am more relaxed with the standard one because I get the signals I need visually to know if I need to pass the car in front or not. I can't tell if my other car is going to drop from 80mph to 60mph all of a sudden until it's basically happened. Better autopilot could help, but then would I end up in this situation?
Blasphemy! More fun to deal with compatibilities of running in different browsers. Seems like we have returned full circle (25 yrs later) to a new form of ActiveX plugins.
And Medium with all respect is a not in the position of doing so. Facebook, Twitter ... these are candidates.
METARs more commonly use statute miles for visibility (indicated by SM), not meters. But they do use things like Celsius for temperatures, and air pressure in hectopascals instead of inHg.
I think the whole 'park' atmosphere actually made westworld more interesting. the stakes were high locally but not globally, and that left a lot of room for growth and interesting stories. Once they jumped out of the park and made the main characters pretty unlikable, the whole thing sort of flopped, to me. Season 2 was the last of that.

I never watched HBO's watchman because I was a fan of the original comic books and modern remakes of almost everything are terrible. You could be right though, I haven't seen it.
It is a thread about pizza, I'm not sure how that implicitly becomes a pizza-ranking contest, but I think you are making my point for me. Do you think I only went to those places because I had kids that played little league sponsored by the pizza place? So confused by your assertion. You are trying to turn everything into an ordinated list because you lack meaning in your life, and I'm sorry for you about that.

>"Also yeah, Ill go ahead and say elmhurst has better food than Bensonhurst just to see what your reaction is lol."

Interesting. They set up a seperate service for it.

I am hoping that companies will do a more "natural" implementation of ActivityPub. By simply making their existing services talk the protocol.

Then you could follow Medium authors via ActivitiyPub, comment on their articles and exchange messages with them.
> I was always taught that it was my responsibility to ensure that I have enough following distance, and am paying close enough attention, to stop if the car in front of you abruptly stops.

Brake testing (suddenly braking hard for no reason, what the Tesla did here) has always been a cause for the leading car to be the guilty party when they get rear ended.

In times prior to dashcams, it was difficult to prove the car ahead did brake to cause the accident, so the rule of thumb was the rear car is probably guilty. But if there was a way to show the lead car did brake, they're guilty.

Nowadays with dashcams, it's a lot easier to prove, so brake testers don't get away with it as much.
The vast majority of organizations in the US already use the metric system in places where the metric system makes sense. Basically everyone who wants to use it is already using it.

For everything else, what's the point in the government mandating it? There's no political desire for it because society in general doesn't care, and society doesn't care because the costs outweigh the benefits. There's no practical advantage to the average person to learn their height in meters instead of inches and feet, or to have to start shopping for hectograms of food when ounces work just fine.
Because they end up migrating more and more functionality to their web side? Deprecating desktop or mobile app functionality or entirely.

So you end up with piss poor “web apps” that half the time require a specific browser to work remotely well and have kludged “offline” modes that break every other day.

Do not want. I know I’m probably in the minority but it’s damned irritating. The UX on most is atrocious and you have to deal with a complete hodgepodge of interface styles and ideas and designs and also hope your browser keeps running smoothly after trying to use multiple more advanced webapps simultaneously.

Oh, but all these advancements on wasm and all will continue improving performance and fixing problems!!!

… you mean stuff that was already solved with native programs? “But you can work on your stuff from anywhere with just an account!”

Oh, like a native app’s data synchronization?

But but…

It would be nice if we had both and both were equals. But that isn’t the case. It won’t be the case. And most companies see this as a wonderful way to vendor lock in even more than before and implement more and more IAP and subscription crap.

No thanks.
I grew up in the US. I only learned the metric system. There was never any point at which we used the customary units.
We converted about 6.5k sqft of living and work space to heat pumps. Fujitsu. Some commercial products due to sizing. Can generally recommend. Controlling heat pump head units is a little different from typical HVAC. Good systems, very reliable, strong track record in residential and commercial space. New units have good tech.
Yes. OBC ~ 52%, SC/ST ~ 22%. Rest General.

Interesting idea. You would have a similar problem that you have with email. It's hard to own a fake .gov email, but many people could be tricked by something like mastodongov.com (which is still currently for sale)
Interesting. Is it possible that the addition of `will-change` caused browsers to relax their default heuristics, believing that websites would use the property as needed now that it's available?
SQLite WASM uses SharedArrayBuffers and Atomics to turn async OPFS apis into blocking APIs (really just _one_ api -- getSyncAccessHandle)

Given the use of SharedArrayBuffers and that SharedArrayBuffers can't be used in a shared worker (funny), SQLite WASM doesn't work in shared workers.

If getSyncAccessHandle was made synchronous then maybe everything would just work. It'd also improve SQLite WASM perf by 30% according to their measurements [1]

Yeah, I'm consoling myself that we're at least using 34% (Dec, 1°F colder this year) to 56% (Nov, 1°F warmer this year) less gas than same month last year, so we at least reduced our consumption significantly, even though it practically locks us into local burning fossil fuels for a couple decades.

The old boiler really was a disaster from an efficiency standpoint. 1950s General Motors (not a typo) oil burner, converted to gas with a single-stage [200K or 0 BTU/hr] burner, drawing combustion air from the basement, and sending 160°F-190°F water to the building and taking up an enormous footprint in the basement. Now has a 95% Bosch combi, drawing combustion air from the outside, using outdoor reset to send 118-136°F water to the building, and hangs on the wall taking up about as much space as two milk crates stack atop each other.

Our grid is ~40% natural gas anyway, so when taxes hit natural gas, they're going to hit heat pump users as well.

While true, the fact that all but 3 other nations managed to do it (though not with 100% transition - I still think of my height in feet and weight in lbs) means that "it's hard" isn't the only reason.
The issue with switching to metric in the US is that there isn't much practical benefit that would offset the downsides. Technically, the US switched to metric a long time ago. No one uses it in their day-to-day life. The US is economically big enough that it can easily sustain using its own standards.

Since there is no practical benefit, most people don't care and aren't going to go to the effort. A vast amount of non-metric physical tooling already exists -- replacing it would be extremely expensive. For things like engineering, it doesn't matter because the units have to follow the values anyway; there are many common unit systems in engineering that are neither metric nor US imperial, and working across unit systems is something you always have to do anyway.

tl;dr: low ROI and high cost to switch
I'm in the Portland area and got a heat pump installed in 2021.

I overbought for sure, as I got a hybrid system that has a gas furnace backup. I've never needed it, but I've had a couple times where I wanted it and it was nice to have. If I switch it from "Heat" to "Emergency Heat", then it overrides the automatic determination of which heat source to use and just uses gas.

I didn't lose power during that cold snap, but if I did, it would have probably brought the temp back up in under 4 hours.
I have no difficulty estimating sizes and weights in kilometers, meters and centimeters, in tons, kilograms or grams, or in assessing the weather in celsius.
But of course time works differently for different objects, which is a main point of mine.

Modern consumer non-business smartphones aren’t even 20 years old as a concept.

Imagine getting an Apple II and expecting application compatibility with a Power Macintosh from the 90s. That’s the exact same timeframe we’re talking about in years, and that’s a massive change because computers weren’t all that mature as a technology in the 70s.

Sure, it is bad that App Store distribution introduces this problem. I’m not saying it’s not bad. However, I’m doubtful that future OS changes from here on out will introduce as many incompatibilities as the ones that took place during the time when smartphones were changing chip architecture to 64-bit, implementing new concepts surrounding sensor and device permissions, and other more fundamental shifts that would affect app compatibility.

On top of that, we’re also talking about a marketplace of apps with an average price of under a dollar.

There’s a damn good argument for PEBKAC (or PEBPAC) if you manage to spend $1000 in the App Store in a lifetime.

Exactly this, someone shared a project they thought was cool and that they thought others might find cool as well.

The hostility displayed towards an open source project in this submission is completely excessive just because it doesn't meet the requirements of many/most users. I'd feel awful if I were the creator of it and read the comments here, which are being extremely harsh about what is otherwise a very nice little project.

Personally I find it very useful, but I'm the type of person who would.
One obvious problem: if a US factory has a surplus of drain pipes they cannot export them. US pipes are 1.5 inch = 38.1 mm whereas EU use 40 mm pipes.

So US companies cannot export surplus and will need new tooling when they want to export. That makes it much more difficult to expand into international markets.
The NVIDIA A100 is like 400W and being dumped by the truckload into datacenters as fast as the fabs can deliver them. I don't think a little "waste" in premium desktop CPUs that are going to struggle to sell more than a half million units is worth crying over.

For sure this is more fun to watch than another liquid cooling overclocking rig.
No, I think the question is why the metric system isn't used by default for most purposes -- like road signs.
The trouble is, I never became a stable after shipping 1.0 as the article predicted I would. But then maybe that's just because I was always pushed to do the next thing that required a volatile.
When that risk-adverse culture is carried over to another space, it just fails and never gets noticed. Risk-adverse organizations get outcompeted by more efficient risk-tolerant ones, every time that such competition is possible.

Risk aversion only works for an entity that has a forcible monopoly in its space. The FAA and FDA do. Another is the Nuclear Regulatory Commission, which exhibits the same behavior: their job is to prevent accidents, and the surest way to do that is to never approve anything at all.
Of course it was, but I am not talking about possibilities, but more on the probabilities side, just to point out:

In a socialist regime, job assignments are made by the state. The state controls most industries and companies, and is responsible for assigning jobs to citizens. However, there may be corruption in the system where individuals in positions of power use their influence to give jobs and favors. It's important to note that the reality of socialist systems can vary significantly depending on the country or region in question and may have different characteristics than described.

But the basics of the corruption system is the same. In fact, low level officials traded jobs, cigarettes, food, for sex if it was a woman who wanted a favor or a job, and rubles if they were males, there are accounts of men giving their wives in order to obtain promotions, jobs, or moving to a another city.

In Venezuela as an example, or Cuba, it happens the same. Citizens don't deal with the State, they deal with low level officials who have the veto power. Basically you become a slave.

That's the difference between a platform and an application using that platform. If SQLite is baked into your browser, you can only use the subset of functionality supported by the oldest / weirdest browser which your users use.

Think about the DOM APIs: jQuery was super popular in the 2000s. Say all of the browsers had decided to bundle it like WebSQL bundled SQLite. Would you be happy using a copy of jQuery 1.7 until all of Apple, Microsoft, Mozilla, and Google shipped 1.8 and all of your users upgrade or would you prefer to update your site to reference the version with the features you want to use? (or switch to a different framework in 5 years)

Browser developers always have to balance the tension of adding something new with the knowledge that they're going to need to support it for long periods of time. WASM is a good compromise position because it reduces performance as the reason why something should live in the browser engine rather than being shipped as an app resource.
No... I'm using Linux on my desktop, and a Macbook Air M1 for my personal laptop. But funny that you would assume so.
I’m sure the cost of daycare and the cost of college are huge factors on a couple’s decision. School schedules are also not built around dual working parent households. A lot more could be done to support parents.
Absolutely. Under Traditional PTO, PTO that isn't taken becomes a payroll line item that is measured and accounted for. Under Unlimited PTO, no such metric exists. I believe we all know what happens in large organizations with regard to the priorities given to things with metrics versus things without metrics?
