Aviation is a sideshow. It accounts for around 2-4% of carbon, depending on how you count its impact. And be careful extrapolating today's trends into a straight line, it rarely works out that way.

You could stop the world from flying tomorrow and it wouldn’t make a dent in your PPM growth.

If aviation busts the carbon budget, so will most everything else, and by vastly larger margins.

Better to direct your limited resources at lower hanging fruit, unless you'd prefer the perfect to kill the good.
The worst ideologues are the ones who claim to be immune from ideology. It's absolutely impossible.
"Saw" doesn't seem like the right word. Granted, apparently, the sensors picked something up. What it failed to do is recognize and categorize; and from there properly take action.

Given the failure of the recognition + categorization system, it would be interesting to know what it thought it saw. Was it filed under IDK, a plastic bag blowing in the wind, what?
I still don't think you've explained how shifting solely to property taxation and away from overall income taxation would work. Your point appeared to be that rich people are better able to exploit the tax code, and I don't see how that would change by shifting to just taxing property. Why not just have large income reserves and not invest in real estate? Why not just get lawyers to better help you exploit the property tax code?

Taxing as a whole is not straight forward. But the idea is that you put a greater tax burden on corporate profits, prohibiting the accumulation of wealth by those who are already in possession of wealth. It's basically half-assed state-seizure of industry to make it palatable to the capitalists.

>Housing prices don't escape the basic economic principles of supply/demand merely because high paying jobs are present. For pricing to become an order of magnitude more expensive other factors must be present, such as limited supply (Emphasis mine)

It's not escaping supply and demand. There is greater demand than supply. This is also common in other urban areas across the country (see New York, Miami, etc) which are large job markets. SF is just particularly bad because of how poorly they address the issues.

>If, on the other hand, it merely exists to cure the ills of homelessness and hopelessness as a welfare system it may become a compromised system for enabling less economic contribution in impoverished social contexts.

Who cares? "From each according to his ability, to each according to his need." This isn't about getting the best economic value from the citizens. It's about taking care of other humans. The whole concept of giving people just enough to not starve but not enough to be satisfied seems like bourgeoisie nonsense to keep a lower working class.

You either destroy the capitalist paradigm, or you exploit people. There is no middle ground.
A self lubricating nut has a lower friction than other nut materials (usually plastic or bone). It'd be more accurate to call it a no-lubrication-needed nut but I guess that doesn't roll off the tongue as easily.

It's my experience that locking tuners do help with tuning stability but I've also seen plenty of guitars stable enough without them.

Even if they don't help a guitar with tuning stability, they definitely speed up the string changing process which is worth it for me.

edit: I've just noticed that the link in the parent comment is for "gotoh style" tuners, not tuners made by Gotoh, and I have to say I agree with you about the low quality of cheap tuners. That said, a good set of locking tuners should only cost you $50-$70. Not a bad price.
> The slippery slope fallacy isn't really a fallacy.

History shows that in the context of policy, especially that of a non-democratic authority, it isn't always a fallacy.

It seems absolutely absurd to me that YouTube should ban gun assembly videos. If the idea is to prevent "mass shooting"-type events (e.g. lone gunman, nonspecific victims targeted by social group), why would a website want to drive these videos further into the underground? It strikes me as sort of "selfish" - avoid responsibility, so a news anchor can't say "so-and-so learned how to assemble his AR-15 by watching videos on YouTube", much to the horror of the liberal retirees who still watch the news (/s).

I hope it doesn't become a trend.

Ask HN: How do you grow a new SaaS business?
I have started a business for my university project (link: https://OrderHappy.uk). I am looking now to grow my business customer base but I'm having trouble doing so. I've been having to devote more time than I'd like to marketing (I'd say a 70:30 split between marketing and developing) yet I'm still struggling to attract new users. I'd love to hear how you guys have grown your businesses and traps and pitfalls that you've fallen into.
It won't scale like that, costs of living will likely adjust up slightly but your landlord is fighting the grocery store for your additional income, ask too high and they'll lose a tenant.

Inflationary shifts like this have been shown to balance out pretty well and a UBI will reduce the ridiculousness of the income disparity by devaluing highly concentrated wealth.
I really thought Flutter was going to just fade away, but it really seems to be picking up speed, in no small part due to Fuchsia as you mentioned.

Looking at the line up for Google I/O, hearing the rumors as we're about to head into it, and with the newest beta release, I'm starting to think Flutter is past the point of being abandoned any time soon.

The real question for me is when will it be stable enough so that I can put it into production without worrying about major API changes breaking everything on the best update.
Many years ago I was coding the UI for one of the first touchscreen check-in systems at an airline. The guy in the next cube was doing weight and balance software for the actual flights. I realized that I could not handle the pressure of thinking that a bug in my code could lead to a crash, no matter how remote the chances actually were.

I'm sure that some of you work on code where lives are at stake, how do you deal with the possibility of truly fatal bugs?
Erlang is the top level user visible language. This gets transformed through several steps to at some point Core Erlang, which ultimately gets transformed into a binary representation that BEAM can interpret.

The only benefit is that it is easier for a machine to do the transformation from Core Erlang to BEAM bytecode than it would be if that machine would have to transform Erlang in one go, similar to how a C compiler will first make a tree like representation of the program in memory, will then convert that tree into some assembly (or a meta assembly language that is still platform independent) which will then be converted to binary. Each of those stages has a corresponding equivalent in the Erlang domain:

Erlang -> C

Abstract Format -> AST

Core Erlang -> Assembler

BEAM Bytecode -> binary

The equivalence is obviously not exact but good enough for this explanation.
>Where does YouTube censoring all videos with gun-assembly instructions fit into a culture where gun ownership is legally a human right?

It fits as part of an international website including many countries that don't see things that way. That's the conundrum the post you're replying to is addressing.

How to get a programming job without a degree – code(love)
A phrasing more to the point is that one expects the input to have some effect on the output. One usually obtains this by, colloquially speaking, performing actions on the input, since if you don't act upon the input in some way, you're going to get a constant result. Of course, you are correct in that some actions don't really do anything, but they're observationally indistinguishable from not acting on the input in the first place.
Reminds of similar stats on stop and frisk - where only a small percentage of stops actually resulted in some sort of criminal conviction. And only a tiny fraction of those convictions were related to the original reason for stop and frisk[1] - discovering illegal weapons.

From the cop's perspective they're looking for a needle in a haystack. Public pressures are especially intense when it comes to anticipating and preventing terrorist attacks or curbing violent crime. But predicting rare events is very difficult. Due to the nature of the problem it's going to be mostly haystack (false positives) most of the time.

So I can understand why the UK police remain unperturbed by 92% false positives. And why the NYPD was largely indifferent to a similarly high rate of failure with stop and frisk.

The problem though is we are the haystack. There's a bit of the snake eating it's own tail here. In order to keep you safe we need to own your privacy. In order to protect your person from violent crime must be able to search your body at any time. Whatever freedom might be I can be sure freedom is not that.

The free speaking engagements is the first step. After you do enough of those, you will get invited to international and big name conferences as a keynote speaker (if you're good at it).

At that point, hiring managers will start contacting you about new jobs with big name companies, for big time salaries. That is where you get the leverage. You'll also start getting offers for paid speaking gigs for both public and private talks. The private talks are nice because they pay well and you almost always walk out with a gift and a job offer.

I never finished the book I started because the publisher pulled the contract when 12 (yes 12) books on the subject came out in the same month.

But I did all those other steps and it worked out pretty good for me.

Using Tensorflow to Create Neural Network with Tripadvisor Data
Windows NT eclipsed Novell Netware for small-to-medium-sized business server usage by the late 90s, and today there still exists many, many businesses that use Windows 2008, 2012, and 2016, so I'm not sure what you're talking about with the "no-starter" comment.
Because it’s only your PR/diff/changeset that’s broken, and you don’t merge broken code?

Are you talking about a scenario where people are just freely pushing to master without a review/CI step? If you recognize the problem with this, why is “deter people from breaking a post-merge CI process” better than “make your CI process pre-merge”?
From the title I expected a piece about censoriousness. How did England go from the libertine Regency period to the social-policing Victorians? Is there a similar dynamic today, of course around different norms? That's something I've been wondering but haven't got to read about so far.
downvote-to-disagree is (or was) explicitly ok according to HN guidelines, so that's why I asked WHY the downvoters disagree. Are the things I wrote not factual (interestingly, this is the inverse of my above complaint...former matters of opinion are now considered matter of fact, but also things that were previously objectively factual are now "considered" matters of opinion)? I've been scolded for not being agreeable, should people who downvote facts not also get a talking to?

As for whether it might start a flame war....well, that is my ongoing concern, that free speech, or more specifically certain opinions are no longer tolerated, or even more specifically, you can say something (unacceptable) once, but if someone disagrees with you, any reply is considered "argumentative" or "not appropriate behavior".

Perhaps I'm completely wrong on some of my beliefs. Personally, I enthusiastically encourage people to disagree with me or challenge my ideas, it wasn't so long ago that this was considered admirable for a variety of very good reasons. When people start believing their ideas are beyond challenge, to me that seems like the sort of thing that's dangerous.
My apologies, I was just slow on the uptake, and this being HN, although I was incredulous, I was also fully prepared for you to come back with a link!

Anyway, I'll take my downvotes and move on. Thanks for sharing the story, I might try explaining it like this to my kids!

> He [Pelton] reportedly received $35,000 from the KGB for the intelligence he provided from 1980 to 1983, and for the intelligence on the Operation Ivy Bells, the KGB gave him $5,000.

Spend $40k to blow a multi million (billion?) dollar operation. That's a pretty good return on investment for the KGB.

> It remains unclear why it took the Soviets so long, although a plausible explanation is that it was used to feed disinformation to U.S. defense intelligence.[original research?]

Reading one of the memoirs of Victor Cherkashin, an ex-KGB officer they were certainly fond of running double agents and feeding disinformation in the process. Well I guess that's a standard spy tactic I suppose. Another reason was probably to not betray Pelton.

Also Cherkashin was working in the Russian Embassy in DC at the time and he recalls the story in his book. After Pelton walked in and was debriefed, they suspected he was probably followed. So they dressed him as a delivery/service person, shoved him into a van and drove away. Apparently it worked because FBI was unable to follow and discover him. He was found later, when he was betrayed by a defector.
Agree, though readers need to parse that advice carefully.

TLDR: Unless you are dying to have the O'Reilly animal in your book cover, go self-publishing or alike, and earn some real money. The OP doing earning-per-hour math on the task of writing a book is very very odd. You write a book investing what you learned in a life or in many years at least, the amount of time to write it is not a meaningful metric.
I really don't think there's as much of a conspiracy as you're implying. People want the best for their kids and upper class people are going to give their kids every opportunity they can to succeed. That means helping them prepare for exams like the SAT. Doing extracurricular activities to stand out, etc.

There are very few people actively trying to prevent lower class people from getting into the upper class, but it's competitive to be in the upper class and there are only so many spots. You don't get to be prestigious by letting everyone in.

The plus side is that if you are from a lower class background and somehow overcome your environment, the admissions committees are tripping over themselves to let you in.
Hence the "if". I certainly hope they will be feasible, but the fact that an alternative may be possible, contingent on the potential creation of currently nonextant materials, is absolutely not a reason to discourage development of supersonic aircraft.

Doesn't Google have a history of being unsuccessful at supply chain? Their Motorola acquisition was a failure on the production side (though some would say a net win on the patent and IP side). Instead of using their tech for supply chain recently, as another example, they went ahead and purchased many of HTC's knowledgable people in Taiwan...

Apple has an incredible grasp on supply chain, and Walmart and Amazon have a similar grasp on logistics. I think a lot of the knowledge in this space is about control and not necessarily solved by tech.
Yes, in Japan there is a custom of briefly tooting the horn to say thank you (for example when someone lets you in in front of them) and they still have problems when people have different ideas of what constitutes "too long".
I had to relocate an opossum recently and it was disappointing for that reason. Unfortunately it took up residence near my house (20ft away under a shed) and for the meantime it's a risk to a tiny puppy we have. It would not bother me if he made his way back in six months though.

Particularly, it's a tool for estimating a limit of an effect in a particular idealized policy circumstance and with other simplifying assumptions.

The simplifications don't represent real world conditions, so the computation is of little real-world relevance though the effect is.

Much of a first-year physics text will be simplifications that apply in idealized conditions that are broadly similar, IME.
Should You Bootstrap Your Startup?
Which used to be the case also for cars -- we even have a standard, ISO 7736 (aka DIN mount), for car stereos that can be swapped when the consumer wants to upgrade.

So in my 2002 el cheapo car, I can buy and install in ~ 15 minutes a 2018 infotainment system with a 7" IPS touch screen, Apple CarPlay, Android Auto, Waze, Spotify Connect, all the bells and whistles you can imagine.

But of course car manufacturers realized this was costing them sales, both in form of less incentive to buy a new car, and less incentive to spend $2k on the "upgrade" option for the stereo when a better aftermarket unit is <$1k, so they moved away from this standard.

First of all, in this scenario, the woman would have at least shared some of the blame.

Second of all, what are the odds that a human who just killed a woman would admit even to themselves that they were the one to blame in such an accident? Practically zero. Cognitive dissonance won't allow it. In their minds, they weren't distracted, at least not enough to take any of the blame.

Kubernetes is cool and all, but there needs to be a lot of simplification for it to be "nice to use". Essentially the problem is that it's the "opposite" of Golang - the number of ways to do the same thing is massive leading to huge numbers of headaches in trying to get things done.

Recently, I spun up a simple pod-to-pod communication example but I found it pretty difficult. If you look up cluster networking in Kubernetes (https://kubernetes.io/docs/concepts/cluster-administration/n...) you'll find a whole fire hose of different options from ingress to calico to fabric and on and on.

This is so awesome. I'm consistently amazed at how much kids can understand intuitively, even when they can't express their understanding in precise language. For example, my partner teaches lower elementary at a Montessori school. Not everyone understands it, but she's managed to teach some basic algebra, including to several of her first-graders.
