In addition to the advantages of trains over flights mentioned by some of the other commenters, trains also:

- Require less specialized crew training, and don't require as many crew members to be equivalently specialized (though you'd be surprised at the depth of training that's still required to crew an Amtrak).

- Can stop, and stop at offloading/transfer points, more easily than planes. In the event of issues this further increases flexibility of the system.

- Have considerably more built-in redundancy than planes, and some built-in swap-ability of components during a trip by removing or replacing cars. I say "some" in italics because I've recently been ... er, very directly acquainted with how critical a single pantograph failure can be to an entire rail line.

- Might, if implemented via state-operated rail or state-sponsored monopoly, offer the ability to replace, deploy, or reroute entire trains in the event of unexpected capacity/mechanical issues. This advantage is a bit of a wash, though, in that we'd probably have more redundancy in air travel if there were fewer larger carriers (this isn't guaranteed and trades off with other issues, but redundancy/flexibility is an advantage of consolidation).

- Are mechanically simpler than planes, and thus require less overhead before being deployed and have fewer "no-go" inspection conditions that can introduce unexpected unavailability.
People don't like to hear this now, but airlines chose the right thing to optimize for. Air travel is rarely that important to have these redundancies, and they vote with their wallets every time they buy economy tickets. Given that safe is a baseline, most people value price over reliability.
100% disagree but the market will decide whose right
I wish I got married in my 20s. Everything is so messed up now.
Unpopular opinion but airline tickets are way too cheap for what they are doing. My last trip to Vegas, the Uber ride to the airport was more expensive than the airline ticket. My Uber money went toward 1. The driver’s labor, 2. The car and gas, and 3. Uber’s (mostly engineering) overhead. That’s it. And it was like $150! My airline ticket pays for pilots with decades of training, dozens of trained professionals and support agents, baggage handling, security, airport operations, sometimes meal service and entertainment, not to mention the wizardry of launching me 30kft into the air so I can get to another state in an hour. All that for $99?

My application - WordfixerBot - was built to help users paraphrase, grammar checking, and summarise texts. The paraphraser tool currently offers basic features for language processing tools - paraphrasing tones to choose from and copy function for result text. I am currently working on adding more features to improve it.

Background story: I have always wanted to build an AI-based application, and when I first came across OpenAI GPT-3, I was amazed by its powerful NLP model, so I just gave it a try and hoped it might work out :D.

I would appreciate it if you guys could give it a go, and I would love to receive any feedback you guys have for my site.

Thanks, y'all :3

What is understanding if not correlations of words and ideas and concepts? I totally respect Penrose but unless he has an noncomputable alternative for the brain then that’s just magic (and completely unnecessary). Now I know Penrose used to have ideas how the brain is actually a quantum computer which uses entanglement. But that is still computable.

Nuclear is relatively slow, but this is a non-argument against it. This is more or less the conclusion I made out of that discussion. Feel free to make your own.
You bagging the username "airtag" just to share this comment is so funny.

Training for these scenarios may help with responding to true black swan events, like Rick Rescorla's WTC evacuation drills ahead of 9/11. But, nitpicking, if you've predicted something will happen, by way of simulating it, it's not a black swan when it does.
Since i use Google Authenticator for numerous services this is going to happen to me one day. So what I did was set it up on more than one phone.
> dying of Covid was considered to be a fine sacrifice to make to keep the economy flowing

What you call "the economy" is actually people living normal lives, trying their best to make joy in a finite lifetime. It is exactly quality of life. Covid shutdowns exactly prioritized quantity over quality.

If as a society we cannot permit the risk dying of Covid or indeed any other risk in life, we may as well stick people in a pod a la battery cells in The Matrix so that they live maximally safe lives.
I made my own, using WGPU and this basic graphics engine: https://github.com/David-OConnor/graphics_wgpu

Note that there's currently no docs or template/examples, and I'm rapidly breaking the API.

The surface plots are just meshes of a grid divided into triangles. When I need to manipulate them, I re-gen the meshes from a nested 3D array.

So, not a plotting lib at all; a flexible 3d and UI lib. Could probably made usable by others with a basic example of how you interact with the render and UI.

Have you tried the Plotter lib? I haven't used it, but looks nice from a skim. https://plotters-rs.github.io/book/basic/draw_3d_plots.html
Some ideas are good. Other ideas are bad.

If people are able to share ideas, some people will share bad ideas. This problem goes back to Gutenberg.

Some will argue that the powers that be owe it to the less intelligent and less powerful masses to make sure to remove bad ideas, and/or to promote good ideas.

Others will point to history and note that banning books, or forcing people to read the “good ideas” has rarely been a successful long term strategy.

I side with those who reference history. History tends to be cyclical. Most thoughts have been thought before. Students of history have learned that manipulating what people think by engineering the free flow of ideas may work great in the short term, but longer term it’s doomed to failure.
The answer? A scam call answering AI bot which engages with the scammer (or the scammer AI bot) and wastes as much of their time and international call fees as possible without giving them a valid bank account or gift card number, Kitboga[1]-style. As soon as you detect the call is coming from a scammer, you push a button and your phone takes it over from there.

Eventually we'll just have a network of AI scambots calling up AI scambaiters and having completely useless conversations in synthesized English with each other for hours upon hours and nobody will remember why.

Any thoughts on how to reverse engineer it to figure out how it is talking to the LEDs? I do not have an oscilloscope or other EE type tools.
This is just GPT3 right?
difference is a human can usually understand they are dealing with an edge case and can try to work-around it or solve it. "AI" just outputs garbage.
I'm sure they know exactly where every plane and every flight crew is at every moment. My point about algorithmic complexity is that even with perfect knowledge, fixing this is a computationally difficult problem. The idea was to show how the properties of algorithms that perform combinatorial optimization actually matter!

Blaming it on the user is a cop out.

At the end of the day they're using the system that we created, and they use it the way we tell them to, so we can hardly blame them for the design decisions we made.

For example, there's no technical reason bookmarks can't be added to the home screen via the app store, and appear more or less identically to apps.

Also: you can work with sub-optimal solutions. Decent approximations exist for many classes of certain problems. Even running simulated annealing or genetic algorithm will get you close to the optimum. I'm sure such a large airliner has a staff with sufficient knowledge of optimization.

Android already has C/C++(NDK, bionic) and Java. Google is stuck with JVM based languages for Android apps because the ecosystem depends on it. There are millions of apps that are written in Java. So that is not going to go anywhere. So the best alternative they could find for Java was Kotlin. Now comes the question of C/C++, for that Go is not an alternative but Rust is. C, C++ and Rust are systems programming languages, Go is not. For performance critical path systems programming languages are used. Watch the start of this[0] discussion and you will soon realise how out of place Rob Pike felt, with regards to Go, when the topic of systems programming languages came up. In early days Go was touted as "systems programming language" with later clarification that what they really meant was "suitable for server-side programming". So Go is not a replacement for C and C++ as a systems programming language.

I didn't make it clear but I think we should be building nuclear today. But that doesn't change the fact that there is little inertia on moving forward with nuclear.

All these discussions centre around changing policy but I have heard very little about actual change happening. Further, we have very little expertise left regarding building nuclear plants so even if we could start building as many reactors as we want, how would we? Then there are the financials, which are heavily compounded by the policy and lack of experience.

Since we need the policy to change to build more, we need to build more so we can actually predict the costs/time, and we need to predict the costs/time for the financials to work... And nothing seems to be being done any of it.

How exactly can nuclear be built in the current status quo?
From the article:

>The website also lacked a button for users to reject cookies as simply as accepting them, CNIL said, where two clicks were required to refuse all cookies while only one was needed to accept them.

No need for FUD and fear mongering, "oh no it's so complicated, every town in Europe has different laws, what can we doooooo we are doomed someone please help us"

And it's not even difficult. We do it every day. When I go to the shop I take products in my basket, and then I extend cash (or a card) to the cashier. I don't ask them if they are sure they want to accept payment, or offer them to take the money only in the form of 10,000 coins of 2 cents, or throw the money in the air and ask them to catch it, etc.

If American corporations were not run by psychopaths this would not even be a debate. Dark patterns are evil and I hope corporations using them cynically will continue to get punished to the tune of millions of dollars.
I know you're just making a straw-man, but can you be sure no vaccine will ever have a component that causes cancer? Even if you can be sure what's the benefit of suppressing those claims rather than just ask for evidence that supports the claim? It's not that difficult.
> Consciousness is an emergent property of your whole body, not just something attributable to parts of it.

What an arrogant statement to make!

All the wisdom traditions of all the ages and of all the places have always taught that consciousness is the Epiphenomenon. The first cause that has no cause.

This is even a scientific statement, because there is an experiment that can be reproduced (and has been reproduced since thousands of years)
If you meditate very deeply for hours upon hours (20.000 to 30.000 hours, is a rough estimate given by the tradition of kriya yoga) you will make the experience yourself.

I highly recommend to look at ORCH-OR (a theory on consciousness by nobel laureat Sir Roger Penrose and Prof. Stuard Hameroff. That substructures (microtubeli) inside biological neurons are taping into the state of the universe by going into superposition and collapsing... It is too much to further elaborate but worth checking out!

Better even, increase you meditations ;))
SSN are supposed to be unique. They are not. If you try to use them as a unique identifier in a database, your customers/end users will be sorry. In the payroll app that I'm currently working on, 111111111 is used as a temporary number. Which ends up not being temporary enough.

Yes, my point is precisely that you can celebrate one thing (moon landings) without celebrating other things (all those bad things the commenter listed that were closely associated with the moon landings).
Why does it need a kernel module, rather than just using the MSR API like similar tools do? Intel's PCM tools for example, show quite similar information, and are available on a variety of OSes..

I am always mystified by assertions that underground CAES systems suffer inefficiency. Earth is a superb insulator, so any heat pumped into an underground reservoir along with the compressed air would be still there when you draw it down later.
He thinks our biological brains get around it by using quantum computation.

Roger Penrose is a historical hero of the physics community and a current embarrassment from time to time. His ideas on things like computation and neurobiology are not worth taking seriously.

It’s unfortunate to see people like the one you’re responding to using his Nobel Laureate credentials to justify his nonsense.
Why oh why do people cite left-pad like this as an example of package bloat? It’s functionality was so valuable it was included in ECMAScript 2017!

> He argues that AI does in no way 'undestand' anything. He goes even further and uses Goedels Theorem to show that 'understanding' itself is non-computeable.

So how do brains understand things? Is he asserting that something is happening in the brain that can't be described/modelled computationally?
Ask HN: What interesting jobs for software engineers exist in climate tech?
On and off, I find myself wondering if the problems I work on as an engineer are important enough in the grand scheme of things. It's easy to conclude that climate change is one of the biggest problems we face today and for years to come.

Which leads me to wonder whether software engineering skills equip us to be part of the solution. Is there a demand out there?

I've been running searches for "climate tech jobs" occasionally, but what I find is sobering and doesn't make me very feel useful. Broadly speaking:

- There's a lot of startups or even more established companies providing SaaS solutions to do footprint monitoring, etc. Sadly, very often this business model seems to be paired with "greenwashing" type certifications. Cursory investigation often reveals plausible critique of the standards and due diligence involved. Some of this may be useful work, but I find it very hard to tell the good from the bad.

- I've looked into a few of the companies working on engineering solutions to climate change, e.g. Direct Air Capture and similar. The proble is that even when the technology works, right now it looks like fossil fuel burners are heavily leaning on them to get out of emission reductions. Additionally, these companies mostly post chemical and mechanical engineering jobs. Software is not core to these products.

- The most obviously-good stuff I've found is e.g. web apps that help inform the public and decision-makers with good interfaces and smart visualizations. For example the NDC viewer and others. But it feels like you have to be "at the right place at the right time" to get involved with one of these.

Overall the feeling I get is that mitigation and adaptation projects world-wide aren't sufficiently funded to lead the tech industry to optimize its portfolio to answer any demands. And even where it happens it's more a slow evolution of existing products or product portfolios rather than greenfield solutions. It seems hard to find an engineering job where you get to truly focus on this problem space - all the action with impact seems to be in the policy space instead.

What am I missing? Are any of you working software engineers in climate tech and have some suggestions for where you see capacity gaps right now?

"Optimizing for subproblems" itself has issues. For instance with a single hub (a complete hub and spoke model), the problem is algorithmically easy. But a) flight distance is much higher, and b) you run the risk of a single weather disaster taking out your entire network, and c) lots of other problems.
My point was to suggest that its useful to understand what's going on in terms of algorithmic complexity. Southwest, because of decisions that they made I should add, is facing an extremely difficult algorithmic problem, and some of the issues of what's going on can be understood by thinking out those problems.
I.E. your algorithms class actually matters
Not available in Europe. Also there’s no way I’m paying for 1 more service. Even if I subscribed to all of them, it passed the point where it’s annoying to check one by one where I can find what I want to watch. It’s time for a meta service in front of all the others, but there’s no way this is coming in the 5 years. At some point, Netflix was simpler than piracy. Now piracy is simple again.
The bar should not be “does the machine understand” but rather, “can the machine be distinguished from a typical human by a test”

And further, for any test we choose we must ask ourselves, “do we expect our ability to discriminate between these two classes, man and machine, to go to zero as machine performance continues to improve”

If we believe that only continued performance improvements are needed to make AI indistinguishable then that means today we’re only talking about differences in quality rather than differences in kind.
I took everything apart but I am not good at identifying circuit components but I suspected things would be easier to diagnose and repair or replace with a little more open info from the manufacturer but that is unlikely.

Knowing how to repair a prelit tree is key to designing a repairable prelit tree.

So to me, your first hurdle toward making what you are talking about would be learning to use a soldering iron, multi-meter, micro-controller programming to a level that you can fix a tree like yours without manufacturer support.

To me, that sounds like a lot of work over a non-trivial time window. Which is to say, the difficulty of making what you are thinking of is non-trivial. But that's almost always the answer to "How hard could it be?" ideas.

Yes, there are people for whom it would be of little difficulty. Those people would not need to ask because they would know how hard it would be and it would only be a choice of if it was worth the bother.

Good luck.
Say no and hang up. If they start something, respond in kind, and ask our allied countries to stand united.

This article made more sense pre-GPT. Now I’m not so sure. I think if a transformer based architecture was able to live update its weights and was trained on the proper abstraction of data, then it could possibly pass the Turing test.

Edit: actually I take it back. This article would not have made any sense pre-GPT either.
Sure, it's not exactly HTML, but looking at the examples it might as well be.
