Stack Overflow had a bad experience with excessively popular questions as described in https://stackoverflow.blog/2012/01/31/the-trouble-with-popul...

They gave it a try - https://stackoverflow.blog/2010/12/17/introducing-programmer... and it veered off into unmanageable and at the end of the day, uninteresting https://stackoverflow.blog/2010/09/29/good-subjective-bad-su...

It had a really big initial peak, but people didn't stick around. https://meta.stackexchange.com/a/200144

There's a place for such questions, it just isn't Stack Overflow. It isn't the trash either... but its that the structure and the framework of Stack Overflow doesn't work for that sort of question.

The problem is that the endless debates tend to drive away the people who provide the answers. Look at the questions on https://ai.stackexchange.com and consider some of the older ones https://ai.stackexchange.com/questions?page=30&sort=newest to the newest https://ai.stackexchange.com/questions?page=1&sort=newest . They really had a problem with the... science fiction questions https://ai.meta.stackexchange.com/q/1283 and appear to have a done a strong change. Sure, those are interesting, but if one wants to ask questions of the experts, they need to ask questions the experts want to answer. There's a site that handles those questions better... https://worldbuilding.stackexchange.com/questions/tagged/art...

The main thing is that it takes some degree of moderation to keep the people who have the answers that people want. This means matching the site to the vision of the site that the people who have answers want to visit... and that's a lot of clauses. Without that moderation striving for what the site could be, you get https://answers.yahoo.com/dir/index?sid=396545663&link=list and there's a reason that experts tend not to go there and try to answer those questions.

As to the its a human issue, not a technical one - I'd suggest giving http://www.shirky.com/writings/group_enemy.html a read. The first of the three things to accept.
At this point it is a request coming from an airline group.

Lots of people think that the fees and taxes should be made clear so that people are aware that they are paying them, but there's no reason that can't be done in addition to showing the actual cost of purchasing a given ticket.
That's how I found out.

It's also somewhat of a tautology because physicists don't really have a 'solid' understanding of what constitutes material. Pun intended.
I'm speaking from personal experience with the people I have met and observed. I do not subscribe to any conservative ideology or the hyper-liberalism espoused by many on this site. I am a reasonably intelligent white male with good parents born in the US with no disabilities so I am EXTREMELY fortunate. However, I also believe in the American social system that has produced virtually all of the technology in the world for the past 200 years that has drastically reduced global poverty and likely is the reason why slavery no longer exists, and I believe those who provide significant value to society should be lauded and allowed to "keep what they kill" to preserve our culture of achievement. While they should be taxed heavily, they should not be required to hand everything away so that people like you, who play doom and complain on the internet, can buy a new iPad with the proceeds of the redistributed wealth, or so that a new senator can spend the government surplus on a vacation and some hookers. Once social mobility, educational opportunity, access to similar healthcare, and basic human rights are preserved, rich people don't owe you crap despite what you think. Our society is clearly not perfect and certainly requires continuous work, but there is nothing stopping a hungry and intelligent kid in the US whose parents feed him and shelter him from becoming a multi-millionaire in this country or even president. If you want more, stop complaining and go earn it. If you think things are unfair, then stop complaining and go help people.
I will second Firebase. It has really matured as a platform over the past couple of years and is a much easier service to work with than AWS.

As to the parent’s question on switching cloud providers though I think it would be non trivial.

Tangentially, that's why upvote/downvote is inadequate — it squashes unpopular opinions and creates echo-chambers/groupthink. The solution is to have reactions that separate constructive/unconstructive, agree/disagree, and so on (a few other sensible categories) and only bury based on being unconstructive…
In which case the appropriate thing to do is answer the question that was asked, then provide the recommendation for the alternative.

Sometimes there are reasons you only have a hammer and really don't feel like getting into an argument on the internet about "how you should be doing it".
Thank you for the letter and the stickers, I have one of them on my bicycle to this day.

This is something I had to learn as well, I guess one of my most upvoted questions falls well in that territory [1].
I just think that Stack Overflow was best when you were its primary moderator and it's arch enemy was Experts Exchange [2]. That battle is won, but the war goes on. Nowadays when the first search result is Quora I have very much the same feeling I had regarding ExpertsExchange back in the day and I can't help thinking that there is lost opportunity for Stack Overflow and Stack Exchange.

I think Twitter's biggest problem with fake accounts is not that they are hard to identify, but that if they do identify them and shut them down, it'll hurt their "number of active users" stats
What is it about "hot reload" that is so appealing to people? Running an app takes less than a second on Xcode. And .NET had "modify, recompile and continue" in 2005 at the latest. I fail to see the revolution here.

Your nonchalant mention of "Xamarin or whatever" means to me you have little experience with that.

You say that Flutter takes the best ideas of UI toolkits, but then say it's mostly web engine developers. So which one is it? Let me guess, they are using Flex as layout? So hardly the "best ideas". Edit: Yes, flex [0]

On the other hand, I don't need to use it to predict how bad quality apps will turn out to be. Just like Electron and React Native apps are bad, so will Flutter apps be, for the simple facts no native controls are used. (React "Native" is not native at all.) Even the best implementation (which Electron and React Native do not have) would still mean bad apps simply because they are not using native widgets.

You seem to only care about developer experience—which I disagree as well. I only care about user experience. User experience is king and developer experience is complimentary.

This may be a large part of it, but its a reasonable approach for the airline to take. By "departing" on time they are showing that they did their job, the actual delays are FAA / Airport problems....so airlines view is "why should we take the blame" because airport ABC is incompetent.
Anticompetitive behavior is only illegal when practiced by a company with a monopoly.
As a person with ADD, I don't like taking the medications. It makes me feel like a zombie and emotionally dead inside. I hated it. It stripped everything of me but made me "productive" (as in acing school work - which did brilliantly). However, I feel it wasn't worth it.

It took months just to feel normal again. For those who were wondering, I took a mix of short and long releasing stimulants. Although, I mainly blame the short releasing ones for most of my troubles.
In the case of things like being rejected by a machine learning algorithm for a mortgage, it should be pretty easy to automate coming up with an explanation for the applicant.

Run the application again with $5k higher income. Keep raising income by $5k until you find an income level that results in approval. If that income level is reasonable for people in general who were approved for similar mortgage amounts and whose other inputs are in the same ballpark as the rejected application, tell the applicant the rejection was for income too low.

You can do a similar thing with other parameters, such as credit rating, length of employment, and whatever else is input to your algorithm that is under the applicant's control. In some cases you might not be able to find a good single parameter tweak for approval and will have to resort to combinations. There will usually be many different ways then to tweak for approval. Use comparisons to similar applications that were approved to pick a reasonable combination of tweaks to base the rejection explanation on.
I disagree. For wireframing, vector tools are essential because of the ease with which you can move and scale elements.

Sketch and Affinity Designer are perfectly capable of exporting production vector assets - Sketch can even export CSS attributes. Sketch in particular has a thriving eco-system of plugins.

An online search quickly reveals a plethora of Sketch templates with pre-made UI elements for all operating systems and platforms: not wireframes, but high fidelity mock-up designs.
Thank you!

That Red Kote recommendation looks great for anyone with a smaller and/or more accessible (and/or new?) tank. Hopefully, some other HN readers will get use from it.

Note that they have both an internal liner coating and an external one with plastic fibre reinforcement.

I wonder whether, if one is installing a new tank, one or both linings are advisable -- stop future problems before they occur. Or whether the lifespans of the liners indicate not applying until they are needed.

It won't solve my particular situation, I guess -- that's more a matter of how much I might end up having to replace, in addition to the tank, due to corrosion of the undercarriage. The cost of the tank, I was ready for. But in talking to my mechanic (good guy I've known a long time), he's come to the realization that once he goes after the tank, it's hard to predict how many additional parts would have to be replaced because they'd prove impossible to reinstall in their current condition. The job can be done, but it might exceed what's worth putting into the car versus towards a replacement vehicle.

I was hoping to get another year or two out of it, at least, but I had no expectation of making it last forever. (I.e. this is not a restoration or similar.)

My problem seems to be just the seam. If I felt I could get a good enough application just right at the seam, I'd pursue that. But that looks to be an ill-advised approach.

That's a nice trick, in the YouTube video. I guess it proves, too, there's a way to work duck tape into any repair! ;-)

I think people might be missing the finer details of this story. This is an example of the system working the way it is supposed to. They are getting a warrant and asking for very narrowly scoped information. If you take your argument to the logical extreme then businesses shouldn't have security cameras either. No crime would ever be solved.
Tesla tried to buy that knowledge by aquiring German robotics specialist Grohmann. When the acquisition was complete, Tesla in classic startup fashion tried to pressure employees into overtime and to cut all obligations Grohmann had to other, mostly German, car manufacturers. This resulted in Grohmann's CEO leaving the company in protest and unions threatening strikes. I image quite a few top execs and engineers left with the CEO and went to VW, BMW, and Daimler. Even lower level employees leaving would be hard on Tesla as those people, despite "just" doing blue-collar work, are highly trained specialists.
There will be a shakeout - but the Deepnet boom is useful because there are several other significant technologies that have been produced since the late 80's which are ready for mainstream adoption: answer sets, tractable bayesian reasoners (MCMC), SAT solvers.. and one of the technologies that enabled deep nets has enabled these massively : big data. And now streaming systems are mainstream they are enabling for another raft of applications using AI.

That's not really a "hack" though. Performance of lambda depends on warm processes, generally not just for connection pooling.

DB connection pooling is simpler in node.js + lambda than php + Apache.

I wold find surprising if Chinese people weren't creative; but what I would be curious to know is if that creativity wouldn't be stifled when it goes against the academic establishment, ie: how easy is it for a scientist to propose and pursue a novel theory that goes against the current scientific consensus - and thus, against his or her superiors' theories? Would that be a problem?

No CEO should earn 1,000 times more than a regular employee
Depends. At least a couple of times a month. And arranging rentals or owning another car for those trips is not really appealing.

Another big reason is that I don't buy new cars. So for an EV to make sense for me it would need to be a used one, at least 5 years old, and still have useful range and battery life.
The designers did well in picking datatypes, though they erred in not including a null value it's a real pain in the ass going to json and losing binaries and datetimes.

The library ecosystem is more mixed though. Python's support is great, Ruby's is serviceable, because it's schema-less Java is very verbose and not very fun, and PHP's stdlib support is just horrendous (though ripcord is good).
I believe that you can't be down-voted, and therefore lose your hard-won points, by commenting. But if you answer, you can be down-voted. So for some participants, commenting is prudent.
> Copyright still has 2017 for end date.

I don't know about this project, but unmaintained copyright years has been the case in almost every project that I've taken the time to look at (and that has them). Unless a project has an active legal team, I wouldn't use such dates to mean anything (for better or worse).

Their Perverse Incentive is probably to shut down fake accounts faster than they are created. Such that they are 90% effective in, say, 5 years so that the active users takes a haircut instead of a big drop.
Another issue with Lambda is that everything goes off the rails if you need to do something that Amazon hasn’t prioritized yet. Let’s say you want a GRPC endpoint, web sockets, http/2, mutual tls authentication, etc. Lambda won’t help you and you’ll be left building up your own patterns for those. Once you have those patterns, then Lambda’s use cases can be satisfied as well.

Also, Lambda doesn’t provide any sla’s on container reuse. They could restart your container multiple times per second or every few minutes. You are at their mercy to keep your containers warm.

Finally, with the meltdown example, would containers actually need to be patched if the parent OS gets patched since the kernels are shared between host and client containers? With Fargate, amazon would patch the base OS and your containers would be safe as they get rescheduled onto patched nodes.

> because nobody wants to check bags any more because fees

I hear this a lot but is there any truth to this? I would think the chance of loss and breakage is a much bigger problem than a few dollars. Aside from clothes and perhaps shoes there's little I am willing to risk checking in. And then again: my tshirts are carefully collected (I no longer wear conference tshirts) and would be hard to replace. My shoes and sandals are comfortable on unusual feet and can hold my arch support inserts well and it's unfeasible to replace them in a foreign city. Even in my base cities it takes a hell of a time to buy new footwear.
I'm not saying there is an equivalence between the nazis and modern day us. I am just pointing out that when we do horrible things, we have to not deny it, not say it's not a big deal because someone else did something worse. We aren't equivalent, but we do make mistakes.

Yes, this is the Apple "Walled Garden" philosophy, which can be looked at as (a) Apple make no money off it, so why allow it? But Apple can sell apps on Android if they wish.
(b) Android security is so bad for the safety of all IOS users we must guard it well.

Added together, Apple can act in an antitrust manner if it wants to, everyone likes to shoot fish in a barrel, and it would take 5 years of litigation to change it - unless some Government body can decide to do it
> a philosophical stance, that everything in the world is physical. It's not something that is likely to be solved empirically and it's not clear how you would even prove it one way or another. Anything as-yet unexplained might yet yield to a physical explanation, and insofar as physics is well-understood, skeptics can retreat into talking about mental states and so on.

Interesting. From a philosophical standpoint I see no quarrel. You could replace "physical" with "god" in your definition and it would read true to many religions. It's when dogmatism overrides doubt, questioning, and humility that people are misguided, in scientific theory and religion.
Sure for a minor incident. But any foreign airline would immediately move their planes out of the US if war broke out. And there would generally be warning signs before it happens, giving them plenty of time to discontinue flights.

If we think about possible real world applications of DL and related techniques, currently at most 5-10% of possible applications are introduced. We have many years of work ahead until the current technologies will achieve their benefits in real world applications.

> you should write a custom UI for each platform you're bringing your logic to

The question isn't of "bringing" your logic to a platform, though. The question is how people who you don't care enough to provide first-party support for, will run your application.

Consider a situation where someone codes native apps for Windows and macOS, but also provides an electron app as source. Who is that app for? Everyone who is using any other platform.

Also consider the "native-ized" apps that exist to wrap web-apps that never created a native app at all. For example, there are numerous Electron wrappers for the Facebook Messenger web-app created by third parties who just wanted to be able to use Facebook Messenger on their PCs as an "app" rather than a webpage.
The more opioids doctors prescribe, the more money they make
No, it isn't. Generally, in mass production, there is an acceptable failure rate where x parts are simply binned because they fail a quality check. It's built into the process. I would assume that Tesla does not over the available overhead to simply toss parts that can be fixed to work rather than tossing them out.

As others have pointed out, it's order n^2, not meant to be interpreted as exactly n^2. I will add that, having done hair simulation for DreamWorks, it's likely that their collision simulations are done on guide hairs, rather than interpolated hairs. So n is usually more like 1k, not 100k. Complete accuracy of hair simulations in film isn't required, nobody will notice individual hairs crossing each other, but you might notice big clumps behaving badly.
Not really, because the price increase sint actually due to real costs on Seagate/wd's side - everyone knows they will just drop prices if a competitor joins that's not part of the collusion. You'd be entering a market with huge startup costs, and once you'd ramped up production prices would drop and your margins would be razor thin.
Searle does not prove that the distinction between "actually understanding Chinese symbols" and "simulating the ability to understand Chinese symbols" is a real one. Physicalists, including me, believe this is just a confusion generated from our inside view of our consciousness, and that "really understanding" is just something a computer program thinks it can do once it gets complex enough to be conscious. At the bottom level it's still just pushing symbols around via syntactic rules (in the case of the mind, natural law).
