>Is BTC really more stupid way to burn resources than making sports cars? F1 racing? Gold mining?

Considering the array of competing cryptocurrencies that consume far less energy while providing more transactions per second and additional features like smart contracts, yes it is. For example. Ethereum has twice as many transactions per second while consuming a third of the energy.

> Why is the thing I consider moral not attractive to the market

Because markets are notoriously unable to price in externalities on their own.

I realize there is a temptation here to throw up your hands and say "well, all human activity emits carbon", especially if you are long bitcoin, but it's a false equivalency. Bitcoin is an energy consumption monster by design, and its difficulty adjustment mechanism neutralizes any attempt at making mining more efficient.

Ask HN: Resources and tips for getting into Machine Learning Research
Hello again HN,
I'm interested in getting into machine learning, but purely for the purpose of contributing to the field. Short term I have no plans of moving to a machine learning job or pursuing an academic career, so what I'd like to focus on instead is on building a solid knowledge foundation and eventually the ability to understand and contribute to on-going research.

I'm currently a software engineer with an electrical/computer engineer background. Had a few courses on signals and machine learning but they left a lot to be desired.

Currently I've started by going through the Fast.ai foundations course which seems like a good start.

I'd like some suggestions on the following:
1) Useful resources for the math background needed. I would prefer resources which actually go into the gritty details as I already have some math background, but also appreciate resources with good insight on how to learn about concepts eg. 3B1B.

2) What path would you suggest to get a decent overview and a solid foundation on the field? For example, suppose you were starting in the field with hindsight, what knowledge would you seek as a foundation and how would you get an overview of the field?

Thanks in advance
There are two aspects. One is the hardware. Coin production is held nearly constant by adjusting the difficulty. Hardware evolves such that hardware from a few years ago is drastically less effective than current hardware, and the difficulty is similarly higher. This means it takes new hardware to mine effectively. With jumps in prices comes jumps in prices of the hardware. And difficulty acquiring it.

Also, the economics change with the price of btc (obviously). When btc is $50k, you can mine very profitably with $.12 kw/h domestic electricity (ie your house). When btc was $10k, you'd break even or lose money.

So if you can get the hardware, and get access to cheap power, yes you can print money. Neither of those are easy. That's the challenge and why it's so easily dismissed as you observe.

The really provocative question is imo, how high will the price of btc go? A lot of people speculate $100-300k. That kind of price justifies a lot of capital expenditure.
I think part of the value of the project is the human curation and attention to detail. The "good enough" semi-automated approach is what is already being done by Project Gutenberg and the like.
Maybe not, but if it turns out a KKK member or Robin Deangelo gave a racist talk, they should apologize for having their employees being "trained" with it. I don't think the conference analogy works fully though. They're optional. These training things are usually mandatory, so they were required to choose something that this insanely racist content was a part of.
I understand the spyware part but one thing i noticed is that i dont get any ads which a lot of people I saw complaining about online. I think ads are location based and i'm outside their zone.
What is their utility beyond being a lottery ticket? That was my original question. Lotto winners have mixed outcomes, so I'm not sure that its clear if those lives were improved. We may come find out they weren't.

State governments have had a monopoly on lotteries for my entire lifetime, so if we've granted that crypto is nothing beyond a lottery ticket, then there is no issue with society regulating it to whatever degree we can agree on.
Sort of related, i've always appreciated Postfix error 221 "I can break rules, too. Goodbye." Nobody would normally see this curt attitude as it is hidden in the protocol, but I find it cute.

This question is open for invention. A blockchain can have no money at all. People can just play games on it and everyone will agree on the objective history of all games played.

For example, you can assume that there is a fixed amount of money initially distributed somehow (many cryptocurrencies do just that).
"point of the tests"

The point of the tests should be to determine what topics a student has successfully mastered and which they need to spend more time on. If each school is allowed to come up with their own standard, it will be difficult to tell which schools are lowering standard. Using it as a measure of school effectiveness is a secondary measure that is really not possible without longitudinal data.
There is one problem with this: It will get on the nerves of the developers that love simplicity.

I'm one of those, and it really gets on my nerves when systems are overengineerd, or use tech that has more drawbacks than benefits for our specific case.

This part especially is so familiar. It tends to get emotionally pretty exhausting, when you've put in countless hours to make so many things good, only to get constantly reminded that the not-as-important problems that were scoped out for the time being, are bad.

In software under active development there is never a shortage of things that could be improved, especially wrt developer experience. It is very hard not to take personally the whining – especially when it typically comes with very, very little actual effort to make it better.

Because I know this pain so well, I only make these kinds of "suggestions" when I know I can commit the hours to make at least a PoC of what I'm suggesting.
I've not seen numbers for that but the difference is usually quite large. For example, Atlanta Public Schools is 14k per pupil while the Georgia state average is 10k.

Wow. This analogy makes zero sense.
Awesome response! I love that @ HN for every shortsighted person there is a longsighted one providing a non-mainstream view. What ratio do we have on other platforms or even in real life? 1 to 100?
What are you talking about here? My argument is rather simple and you are wilfully misinterpreting it to make your statement. If you want to game, at 1080p, there is very little reason to spend money on a big upgrade, even going with 3xxx series is an overkill.

> Last time I checked, there weren’t all that many games that run at 60Hz 1080p and never dip.

CITATION NEEDED.

The 3060ti is benchmarked at 4k hitting mid to low 50s in high settings in Shadow of the Tomb Raider and hitting 100fps at 1440p with 0.1% minimums at 90fps.
Oh, pish and tosh! That's too much engineering! Instead, handwave about "eventual consistency" and save millions in infrastructure costs! Totally worth it for the benefits of being truly abstracted from your data storage layer. Because, you know, people change their database back ends more often than they change their sheets.
Very interesting, thanks for the explanation!

When you get someone who’s willing to offer up a lot of information, it’s great. And when you don’t, then really honestly try to understand them and their frustration. When you get to the bottom of it, you’ll come away with something useful and they’ll know that you care enough to try to make it better.

I recently jumped on a call with some people from Miro. One of them had left a calendar booking link in a forum for something else and I tenaciously scheduled myself in. When I spoke to them I said “here are my frustrations and I want to give them to you know before I just get into the product and learn to live with them and can’t articulate them anymore”. To their credit they took the call and listened. They got something and I was happy.
One thing I always wished for was a comment to visually show how much work/though/research/effort the commenter put into it, as described here: https://news.ycombinator.com/item?id=23078161

Telegram is not at all secure compared to Signal (in theory). However it has an awesome UI and lots of nice features (most of which are lost using secret chats).

For the longest time these were exclusive features to telegram compared to Signal:

* Delete messages at other party ("undo"), critical for deleting accidentally sent nudes.
* Username only communication
* Stickers (silly, but well kinda fun)
* Bots (very easy to make your computer talk to your phone or a group this way)
* link preview
* Self messages as easy link/file sharing between devices. Super useful.

Signal is slowly catching up, but it's so buggy at times, I am starting to really hate it/distrust it (I also dislike MM's personality/opinions). Matrix seems to move at a better pace, with more useful features already (e.g edit, markdown, some fun things). I am happy to get rid of telegram for Matrix. One feature better then the other already: resync of lost messages from the distributed network and no reliance on telephone numbers as UID.
Yeah; even without frontend code, JS is surprisingly compelling. It's easy to hire for, easy to write reasonably performant IO code in, the footguns are pretty much all well documented and generally understood (rather than requiring knowledge of the deep magic to debug), library support is top notch, and as a language it supports both OO and FP, while being pretty small in scope, terse without encouraging too much code golf.
Regarding the criticism: How is it different from any pentesting tool, portscanner, meta search engine, shodan.io (which you could use to try to find unprotected babycams and whatnot), et cetera, on principle? I know it's creepy, but obviously this is portraying a serious and widespread flaw in how we treat privacy on the net, and for that flaw to be fixed, proclaiming the tool as evil doesn't do it, and actually is counter productive?
>But there's a decent chance that the cyanobacteria and friends would survive and, after hundreds of millions of years, restart the evolutionary process.

I think it's worth noting that on this timescale, we don't have forever:

"In about one billion years, the solar luminosity will be 10% higher than at present. This will cause the atmosphere to become a "moist greenhouse", resulting in a runaway evaporation of the oceans. As a likely consequence, plate tectonics will come to an end, and with them the entire carbon cycle... Four billion years from now, the increase in the Earth's surface temperature will cause a runaway greenhouse effect, heating the surface enough to melt it. By that point, all life on the Earth will be extinct." - from https://en.wikipedia.org/wiki/Future_of_Earth

I submit that this is probably Earth's only chance at a spacefaring civilization, and therefore Earth life's only chance at escaping the planet (and thus surviving the death of the planet). If we flub it and cause a mass extinction without anything to show for it, it is the beginning of the end of Earth's story.

You don't even have to go that drastic. I was also tired of the "new technology treadmill" in software development, so I just changed roles in the same industry. Did a little product management for a while then settled on project management--for those same software companies. The pay is much worse but at least I'm not spending my time re-writing working software into "non-working software, but hey, it's in Scala."
It is. It's funny how some neolibs don't see it that way, but the vast majority of people see it.

Also its limited market cap and halving schedule will probably eventually phase out the energy consumption. Provided people are not willing to pay hundreds or thousands of (current day) dollars for transactions.

Edit: And if they are willing to pay that much that should be a clear sign of the value provided by the network

Edit2: And wether this will also phase out Bitcoins security model will be very interesting to observe across the next 10-20 years (depending on when btc will hit its market cap threshold in real terms)
Script-Fu has been based on TinyScheme for quite some years now.

I think Diplomacy is a super interesting domain for AI research, too. It has a lot of natural language (over a limited set of topics) as an important component, and multiple agents taking turns simultaneously, with fluctuating alliances.
South Australia, which generated 60% of its electricity with renewables last year, is installing synchronous condensers to provide some kind of grid stabilisation. (The current conservative government is aiming for net 100% renewables by 2030 and 500% by 2050.)
Given the enourmous costs of decommissioning nuclear power plants already I fail to see how a reactor containment that lasts 10-20 years at best improves the situation.
ETH2 doesn't 'exist'. There is a heartbeat chain right now, but it doesn't actually do anything. Getting to the next step(s) is the hard part.

Full PoS decentralization does not exist yet. Many attempts exist. Some better than others. Sadly, the complexity (rube goldberg) of PoS far outweighs the simplicity of PoW.
>is Bitcoin an objectively worse usage of those chips than playing video games?

I have done a lot of activities in video games that would require significant CO2 emissions in real life. Potentially millions of tons. So yes, it's much better. There is also a significant population of software developers that picked up programming because of video games. Economic simulation games can help you develop an intuition on how to run a company and how they work without having to risk starting a real company with the potential to fail and ruin you financially.

Meanwhile the only worthy claim that Bitcoin has is that it's a middleman for central bank money. Yes it probably funded a lot of good economic activity, but it's the job of the central bank and government to do that. If they didn't fail then Bitcoin would have literally nothing to do.
>Atleast until the inevatible hack

LOL, yeah, I always forget about this one.

This, btw, is also something that makes crypto "different": the exchange can always pretend it wasn't a scam and blame it on a hack.
Agreed. Vitalik time = Valve time. I figure two years, Q1-Q2 2023 is most likely.

> I am complaining because it goes against my interests.

So you are already certain you want to buy a used 3060 next year?

> I never said mining isn't affecting demand

You said "NVDA's stance is that miners are the reason for scarce GPUs, but it is not."

> the crypto rally started loooong after NVDA had supply issues

This is irrelevant. You mean this time, right? There wasn't a supply problem last time before bitcoin miners bought everything. It doesn't make any difference to gamers which contributor to scarcity came first, when you're talking about 3060 sales that haven't started yet.

> I am tired of this conversation and you are either taking my sentences out of context and blow them out of proportion.

I think you're taking this entire issue out of context and blowing it out of proportion. You claimed gamers are being screwed, when they're not, they're actually being helped. Many gamers here and on other threads are happy that Nvidia is taking steps to curb miner scalping of the 3060. The change here is to a single model, the 3060. Segmenting that market over this single model helps gamers today, and is not going to kill the second hand market for gaming cards. All other models will be untouched, and the 3060 will still be available second hand.
I’m guessing that is because nuclear is often framed as a solution to the climate disaster.

If the discussion was simply: “see how cool of a technology nuclear power is; see how nuclear powers the latest mars rover” I would not guess there would be a lot of backlash. However in this thread you see a lot of: “wind and solar has some problems too”, or “nuclear waste is better then the warming of the planet”.

The problem with pitting nuclear as a solution to the climate disaster is that there are existing technologies that can solve the energy part of it, those technologies are primarily wind and solar. And there is ample reason to be skeptical about how well nuclear could solve it. So naturally when someone states that nuclear is good actually at solving the climate crisis, a natural response would be: “well actually, it isn’t. Wind and solar is”.
There are other technological fields in which capable tech has been kept out of commonly available products in order to prevent people from abusing it.

For whatever reason, techies that are in the information discovery space can't help themselves from showing off how clever they are despite there being very real security risks to random bystanders.

You mention penetration tests here (?), are those really less time consuming and more effective than taking 30 minutes to review a library?
Lifetime analysis doesn’t even show up in Rust compiler profiles. It takes 0 seconds.

Rust lifetime analysis is a function-local pass. It never needs to access any state outside the function. It can be done on all functions in parallel, etc.

I've been using React since 2014 or so.

I can't speak for Angular or Vue, but I'm 100% sold on Svelte. It cuts out all of the crap that React and Redux introduced (lifecycles, hooks, boilerplate, etc.) and boils it all down to fundamentals. You can read the entire docs in a day and fully understand how everything fits together. I dare say it, but Svelte's docs are a breath of fresh air. It's rare that I read documentation and want to keep reading it.

To me, that's what boring tech is about. It's about finding the simplest, cleanest way to do what you need to do. I hope Svelte takes the path of long-term stability over features and complexity and innovation for the sake of it. What they have right now is a solid foundation.

> convoluted bullshit like redux-saga

Wait until you meet saga's bigger brother RxJS/redux-observable. Someone on HN once mentioned JIRA was using RxJS and I realized "ah, that explains why JIRA is the slow pile of absolute shit it is." From just knowing a company is using RxJS I can already guess at the type of internal communication and politics at play in the company, as well as what their code base looks like.
