a one way trip to Mars is the least of the problems. many have volunteered already.
For the first question, one answer is the high price of organics. For your second question, there are many options. One promising option is targeted pest and weed control using cameras and image recognition and maybe even lasers. A system like that was actually mentioned on HN a couple of weeks ago.

Another is using biochemistry to make pesticides that degrade and disappear before the food gets to market.

Another is to bury seeds individually in the soil without plowing the soil, thus protecting the seeds from pests and giving them advantage over weeds whose seeds have to start on top of the soil.

So there are many ideas out there.
"Scale free networks" dont collapse or something.
That sounds pretty big to me.
Earth's land surface is the same size as Mars':149 vs 144 million km².
Ask HN: Can anyone recommend a high-quality document camera?
I'm looking for a setup to scan handwritten notes (A4 and index card sizes).

I'm not interested in a janky cardboard setup, and it should be somewhat compact (maybe foldable), to conserve desk space.

Ideally, it should:

* show up as a high-resolution webcam and work on any OS.

* capture 4k @ 30fps, so I can use it as a "live whiteboard" too.

Thanks in advance!
I'm the author of FakeYou.com and can speak to Tortoise and the TTS field.

Tortoise produces quality results with limited training data, but is an extremely slow model that is not suitable for real time use cases. You can't build an app with it. It's good for creatives making one-off deepfake YouTube videos, and that's about it.

You're looking for Tacotron 2 or one of its offshoots that add multi-speaker, TorchMoji, etc. You'll want to pair it with the Hifi-Gan vocoder to get end-to-end text to speech. (Avoid Griffin-Lim and WaveGlow.)

Your pipeline looks like this at a high level:

Input text => Text pre-processing => Synthesizer => Vocoder => [ Optional transcoding ] => Output audio

TalkNet is also popular when a secondary reference pitch signal is supplied. You can mimic singing and emotion pretty easily.

These three models are faster than real time, and there's a lot of information available and a big community built up around them. FakeYou's Discord has a bunch of people that can show you how to train these models, and there are other Discord communities that offer the same assistance.

If you want to train your own voice using your own collected sample data, you can experiment with it on Google Colab and on FakeYou, then reuse the same model file by hosting it in a cloud GPU instance. We can also do the hosting for you if that's not your desire or forte.

In any case, these models are solid choices for building consumer apps. As long as you have a GPU, you're good to go. If you're not interested in building or maintaining your own, you can use our API! I'd be happy to help.

That’ll likely go about as well as making a deal in RuneScape. Though the hacker doesn’t have many options.

>How will Apple recoup the cost of designing a powerful chip for a product like the Mac Pro, which is presumably their lowest-selling product?

Which is the question I have been asking since 2015. From a cost prospective it never made any sense. Presumably they will wait until Mac Studio becoming powerful enough to fill the gap.

>but the Mac Pro seems to be a clear case where using a powerful off-the-shelf Intel chip makes more business sense right now.

It surely does. Except it will be the only Mac in the lineup without Metal Support and Apple's increasingly important NPU for Machine Learning features. I dont see it as a good trade off.
Isolation when you're a kid means that your parents spend more time with you (remote work) and you don't have to be bullied at school.

Win-win? I would have loved isolation when I was at primary school.
What do you mean? There are several such risks, including the ongoing mass extinction event.
Even if I expected to be able to collect, I wouldn't give good odds on a bet that the moon or mars will physically still exist 1000 years from now.

Von Neumann machines have an existence proof in ourselves, and make it fairly fast to disassemble planets into a Dyson swarm. (I think Dyson swarms are a bad idea, and will grind to dust that blows away to interstellar space in the solar wind in geologically short timescales, but that's a different problem).
> What if one of my inputs was an imaginary number?

Then the code would call that out and not compile and run until you handled that case (at least in F#, i believe ocaml and haskell have strong typing as well for this reason but it's been awhile).

One of the huge upsides of most FP is letting the compiler do a ton of the heavy lifting because it can better check the "sanity" of what you've told it to do. If it's possible to pass an imaginary number to that function, it will say "hey, you could pass an imaginary number to this, and you don't handle it, here's some red squiggly underlining until you deal with that".

There's lots written about this. Designing to not represent error states and domain driven design being the two main topics i've come across that really hammer home how a strong typing system and a functional mindset can create extremely bullet proof code.

It's trivial to debug (mostly because 90% of the time, if it compiles it runs) and it's trivial to adjust (because the compile errors light up everywhere you need to adjust and you just do that).
I figured he’s a guy who works in the national security sector and didn’t want his extra curricular work drawing attention to himself.

If he had to pass occasional polygraphs, it could create some weird situations.

And if he signed a contract giving all intellectual output to his employer (including side projects), he could find himself in a lawsuit.
Thanks! It has been excellent luck. I always know what I’m debugging because the input and output are the only factors I have to consider.
You aren't "most people" though.
I wish we'd charge a tax here in WA for people using studs. They're legal for part of the year but I see taxis and other cars rocking them all winter in Seattle tearing up the road, you can hear them coming. We get maybe a week of stud worthy traffic a year. This is not folks going up the mountains to ski. But they tear up the road something fierce.

Reading articles on Twitter? How about no?
I buy Mac Mini because OSHA once demanded (and I find it’s not a bad idea) that I use screens instead of laptops to avoid employees spending 7hrs bending to neck. So they have 2 displays at work and 2 displays at home, and a Mac Mini, total 2300€, better than a 2800€ Macbook Pro + screens.

What is the state of the art, do all of you simply buy a top-notch Macbook Pro and work on it all day?
Yeah, that’s a common analysis people seem to miss even though Apple is very clearly vertically integrated. Software maintenance costs are so much significantly higher that unifying HW is significantly more value even if the margins aren’t as good. The high end macs serve as cachet status symbols amongst the creators and designers which tend to contain a lot of trend setters + mind share + creative software being optimized around the macs which then means that hardware is purchased at disproportionately higher levels (+ potential downstream effects where if you’re mostly a max shop already, shouldn’t you just get the MacBook Air and other Apple devices to simplify corporate device management?). Also a unified HW platform ALSO reduces software maintenance costs for partners and which is a nice virtuous cycle of encouraging that porting to happen. Apple has a uniquely holistic view of the market place that they’ve cultivated over decades and I’ve seen no sign that they’ve ever lost sight of that like many competitors due at much smaller market caps.
OTOH, we can build a lunar space elevator with existing materials because of the lower gravity (even despite the longer distance to L1). Not sure, can we manage that with Mars?
You’re mistaken.

The principles of the economy are quite clear. If people have incentive to do something, they will. If you alter incentives, you alter behavior, everything stems from that.

The problem with making predictions is that the macro economy has billions of variables which obviously all cannot be realistically modeled. That doesn’t invalidate the validity of theory. Economic theory works just the same as physics if you were able to observe and model every value accurately. Most physics problems deal with far fewer variables and can be simulated and replicated quite easily.

In this case its easy to predict because Powell has indicated for all intents and purposes that he will create a recession. And if he wants to, he 100% has the power to do it regardless of any other variable.
So you missed the part where I wrote that I've run Linux on 2 of them for years with no issues. I didn't mention that I use it daily.
Kids are just allowed to get away with it. If adults were allowed to beat others with no consequences - it would be happening everywhere.

Sadly - teachers encourage the "macho" "don't tatter, be a man" attitude to have less work. Hence bullying. Imagine if judges did that :) "So he stole your book, so what, be a man, deal with it yourself". "I don't care who beat whom - just shake hands and leave me be"
The obvious choice at this point seems to be just abandoning grades at Harvard. Any reason not to?
In a group of 3 or more (especially more) people, there is probably no way to avoid this happening to at least some of the participants multiple times. There simply isn't enough time to get every word in before things get tiresome and people need to re-arrange.
There is something very wrong if they don't have reflection in 26. It is sorely needed.

I thought the same. Schools are very, very much like prison and the schedule is so intense. I have so many issues with it. Many children seem to say they enjoy school, but I bet they aren't the ones at risk of suicide. Bullying is a symptom/consequence of the unhealthy prison-like environment.

I've always wondered about the history of eating raw meat. My family personally doesn't eat anything raw because of the news reports we've read of people getting sick (or worse) after consuming raw meat, and we make sure to only eat fully cooked meat.

My grandparents' generation also seem more familiar with fully cooked meat, I'm wondering whether raw meat came along more recently and where it originated from. At least in the West.
Topological sorting! So important
In a world where it can be read and written at will, natural mutations will be irrelevant even when they occur.
Not really. The current admission system is such that students with slightly lower grade would likely not make it. So, only those who make it are the ones who haven't taken much risks, focused on their grades, kept taking the subjects where it's comparatively easier to get a higher grade, and then the curriculars which are standard and augment the profile. Tests/SATs are also standard ones, and since top Ivy-leaguers only focus on a handful of things, it's important to maintain high score in that. Many students who experimented with a tough (but interesting) course in high school/undergrad, and got bad grades in 1-2 subjects will likely not make it.

This results in a higher proportion of admitted students who are risk-averse and afraid of failure. If that is the input, very improbable that it would be much different with them once they are in college.
This assumes you're writing generic, mathematical code. Maybe that's common in Haskell, and I agree that there often aren't helpful names in that situation.

But usually, if you're working with a list, it's a list of something specific, and the names should reflect that. If we're doing graphics and those (x,y) points are interpreted as points on a graph, then it's really:

moveUpOne = (x,y) => (x,y + 1)
map(moveUpOne, points)

Or maybe it's moveDownOne? Depends on your coordinate system.

Similarly, you're probably prepending to a list for some application-specific reason. The code should use application-specific jargon.
It's already part of Bitcoin: You'd simply assign your coins to a 2 of 2 multisignature with your escrow service. It's implemented in practice too, in varrious forms including ones with timeouts in case the escrow service goes down or tries to extort you itself.

It turns out people mostly don't want this.
On teacher empowerment, there are two views :

One is that the teachers have been stripped off all powers. Just today I was reading some article from hacker news where the teacher was complaining that all kids from the latest freshman year gave her/him the finger when they were asked to show their hall pass.

Other side of the argument is that if teachers are empowered, then it is documented sufficiently that some teachers (not all) absolutely abuse their power and exploit/harm kids in even worse ways.

I dont know whats the solution. I hope I come out more wise from someones comment here.
What a weird comment. The rest of the Balkan is still outside Schengen. You are going to be fine. They are all stable countries.
why do we even care about all this. establishing a space station on mars to make it easier to travel the rest of the galaxy.. is already circular logic but we're 100s of years away from achieving that now. 20 to get a human there. 30 more to build anything habitable and then we don't even know if its self sustainable but if it is.. 20 or 30 more to build a viable space center anddddd... we haven't actually improved life at all, just explored a sliver more of the galaxy and none of us will even get to witness it .
i suggest using NeRFs instead of pont clouds... it's a fun experience with the toolkit
No it doesn't. Where are all the articles and stories from the last, oh idk, couple hundred years about how everyone is miserable at school? Sure, no one likes homework, but if you've ever been in a school, most people are having a good time.

Can we stop normalizing trauma and problems with ones social life? It's not the norm, stop pretending it is.
Grew up programming for fun as a hobby. Came to the same realization you did after working at a job that was not fulfilling after graduating in my field. Thought if I loved doing it for fun why not try it as a "real job".

Applied at a bunch of places even though I had zero work experience or matching degree credentials. What I did have though were a bunch of side projects that I had worked on...

Interviewed with some companies and found out that I was actually pretty competent. That process and working at said companies gave me the confidence boost that I needed to know I wasn't fully kidding myself about my skills. Rest is history.

I feel like if you love it as much as you say you do, you should probably have similar projects ready to show. Not these side projects for the sake of getting hired or bootcamp type demo things, but things born out of your passion.

Take this with a grain of salt for today's age, but this is what I did back then (10 years ago..showing my age here haha).

There are definitely applications of Smalltalk outside of GUI development, e.g. in robotics: http://www.esug.org/wiki/pier/Robotics

One example is NXTalk, a Smalltalk system (with its own VM implementation that differs from Smalltalk-80) developed in Robert Hirschfeld's research group (hi Michael! :)) at HPI. NXTalk runs on second generation (ARM7-based) Lego Mindstorms robots in 64kB RAM and 256kB Flash:

This is believable; "Online" culture, which has increasingly been occupied by young kids, has been on a worrying trajectory for a while now.
It set off nonsense alarms in my head, though I don't have first-hand experience - but I had some ideas on how it could be disproven. I went to archive.org and found a book about fish preparation from 1977. Searching for "sashimi" (raw fish sushi) shows several results, including an entire section about it. This tweeter is full of shit.

Low volume simply means higher unit prices, doesn't it? The Mac Pro as an explicitly professional high-end machine is OK to be expensive. Its USP compared to fast x86 machines is that it runs macOS.

The line blurring ones are the ones taking the comprising position right? So you're saying you prefer Javascript, Rust and Go?
Paging George P. Burdell, paging George P. Burdell.
Yeah, I've worked with dataflow languages and they're a very good fit for data transformations (not so much for complex runtime control flow). Functional-reactive languages like spreadsheets also make it way easier to reason about than imperative programming.

I like environments where you can keep visualization aids close to the code to which they apply; nowadays, that means using online notebooks a la Jupyter and ObservableHQ, or at least markdown files with a preview plugin integrated in your IDE. There you can represent diagrams as code, like Graphviz and Mermaid.

I long for the day that those visual representations can be accessed programmatically and used as part of the code itself, like VB6 interactive widgets were created graphically yet usable in the application; e.g. creating state machines visually by representing states and transitions as boxes and arrows, then compiling the diagram to add conditions and access their values from code (there are some libraries doing this in some environments and languages, but I'm not aware of one that is portable to many languages). I think we're really close to that being possible with modern languages.
A while ago someone mentioned an old test from an American high school somewhere. One of the questions on that test was "name the organ responsible for purification of the blood".

This question is impossible to answer because there is no organ uniquely responsible for that. It's an important function served by several organs. Most prominently:

1. The kidneys are responsible for filtering certain toxins out of the bloodstream and ultimately getting them excreted in urine.

2. The liver is responsible for filtering other toxins out of the bloodstream and ultimately getting them excreted in urine.

3. The spleen is responsible for filtering defective blood out of the bloodstream and ultimately getting it excreted in feces. (Which is why feces is brown, incidentally.)

Without having attended a 19th-century anatomy class, there's no way for me to know what the person who wrote that test was hoping I would say. It seems pretty likely that I know more than he did, but that won't get me a good score on his test. Was that an easy question? Hard?
> But there are certain cultural and demographic factors in play in such East Asian cities, which are often considered a bit taboo to mention.

If you aren't going to mention those factors, why hint at them? Just to annoy people and puff yourself up by insinuating you know something special that others aren't willing to hear? Just say what you mean -- or don't even bring it up.
One thing I actually really like about the big tech companies is they will ignore low grades if you interview well. I had a semester where I failed almost every class due to a life event and was too proud to admit to my parents I should probably just withdraw. This dropped my gpa from a 3.3 down to a 2.6. Two years later when I graduated my GPA was still below a 3. I remember I was sitting at an interview with John Deere and they told me that someone with my academic failings probably wouldn’t do well at John Deere. Broad rejections from General Motors, ford, Boeing, many others. But Microsoft and Google did not seem to care at all. I was told I got a solid yes from all my Microsoft interviewers and was actually able to negotiate a level bump up and a larger signing bonus. For me it showed that Microsoft/google are thinking holistically in their HR decisions, and only use GPA as a signal. I hope my success at Microsoft since then is an indication that they made the right call.
I mean, that's the argument these schools make.
That's not even remotely true. For one, we have barely scratched the surface of the psychology of living in an Antarctic outpost, and already what we've seen doesn't suggest long-term viability (decades instead of months). Perhaps with more people, the problems could go away, perhaps not - there's no reason to find out on Mars.

Yes, Harari echoes this term in some of his speeches, asking what to do with the “useless class of people” that emerge in the wake of the AI Revolution. Instead of asking whether we should be evaluating the materialistic “usefulness” of human beings in terms of the purely economic value they generate, or even whether we should be pursuing technologies that will create these conditions, he satisfies himself with questions about how to keep the “useless people” out of the way with drugs and the Metaverse.
