You've clearly never played it nor read any of the community discussions about the game. The #1 complaint is (or was) loading times. It's why I've personally stopped playing years ago.
>Why are nuclear power construction costs so high?

Because there isn't enough will to make them cost less.

China is building lots of nuclear power plants.
Meanwhile GitLab 15 just launched with features that actually help devs...
Even more brilliant that any Russian speaker can realize exactly same without a dictionary, it is just a rare form of делить word which means "to share".
According to the results, 53.62 percent of ApeCoin participants intend to stay on Ethereum in the medium term.
Off topic but I’m really curious, why are these taxes a percentage? What justifies paying $0.1 for every $10 transfer, but $1 for $100? Is it more complicated to move $100 than it is to move $10? In the end it’s still a single transaction, right?
MedCrypt (YC W19) Is Hiring
No, that's not right.

You need to read up on it more as it's clear you haven't truly understood the puzzle.

The host knows what's behind the doors so he'll always eliminate a wrong answer.

In the opening, you pick one door. That's a 1 in 3 chance of being right.

So there's a 2 in 3 chance it's in either of the two remaining doors. He simply eliminates a wrong answer.

Thus, 2 out of 3 times you win by switching. You win 1 in 3 times by staying with your original choice.
This kind of exercise is underrated. A similar one from a former job: the takehome assignment was something like "Here are some CSV files with sanitized real data from our business. It needs to be converted to XML. Use Java (the language our team mostly used then and there) and expect to be judged on your code readability" IIRC there may have been something along the lines of "Bonus: Now we want to be able to convert to/from JSON and perhaps other unknown as yet formats. Refactor your code accordingly"

Other than not using a library, nobody can complain it's unrealistic. Real enterprise devs spend a fair amount of time munging data from one format to another or otherwise "gluing" pieces together. And the kind of person I'd want to hire should be able to complete it to quickly to complain about a "time consuming take home assignment"

And it provides plenty enough opportunity to make sure you're hiring someone who writes code that is pleasant for their teammates to work with.

IIRC the process before that was just the usual 5min recruiter chat and after it was a single on site panel interview before offer.
This reminds me of the two envelopes problem

https://en.wikipedia.org/wiki/Two_envelopes_problem
I want to second or third the recommendation for Ted Chiang. Basically all of Chiang's stories could go on any "best short stories" list.
Credit card fees include reward systems (points), zero liability fraud protection, extended warranties, car rental protection, dispute resolution/chargeback systems, customer service, support for tens of thousands of transactions per second, airline lounge access, priority entertainment tickets, airline miles - the list goes on and on.

Whether you need any of these is debatable of course but it’s extremely disingenuous to consider it an apples to apples comparison seeing as blockchain provides literally none of these things.

For large transfers (a billion dollars) the banking transfer fee is likely zero. I don’t pay for wires with no limit and my status/relationship with banks is nowhere near where it would be for a billion dollar transfer.

Oh and wire transfers provide quite a bit of protection too. I recently had an international wire transfer where the recipient provided the wrong account number. For $10 the funds were returned. With blockchain they would’ve gone up in smoke and lost forever.

People make mistakes. Payment information gets compromised. Fraud happens. As long as blockchain is based on ignoring these fundamental truths it will never achieve any meaningful adoption.
It's all good and well that bitcoin is cheaper than credit cards for billion dollar transactions, but that is not really important for all of us non-billionaires. For smaller amounts, the fixed cost of a bitcoin transaction can make it a significant amount of the total. L2 networks would be nice, but "work is being done" for years now so let's wait to see if they ever get that working properly before touting possible future innovations as a current benefit.

I don't imagine anyone ever uses credit cards for billion dollar transfers anyway, normal banking is good enough for that. I just checked and the business account that I use for contracting has EUR 0.10 flat fee costs per transfer to anywhere in the SEPA region.
I agree on filtering people out. Most I try to teach, but really just want the end product, and that's not nice.

I'll try next time on filtering thanks!
They didn’t say that’s what they were doing. Now they do. The feature still exists today on brand new phones.
L2 is pushing the problem a bit further away, but it's not a long term solution. All L2 solutions in existence are fundamentally centralizing (it doesn't have to be, but it's a lot harder and since most cryptocurrency speculators don't actually care about centralization it's much easier to do it that way, and L2 solutions are already super complicated anyway) and they only offer a maximum theoretical transaction count improvement of about 500x in a very optimistic case[1].

Except 500x is not nearly enough. It may be enough to temporarily drop the fees but it a post-blockchain world where everybody does dozens of blockchain transactions a day, be it to play a game or buy a coffee or ride the subway, it's not ever close to being sufficient. Your scaling factor needs to be millions of times better.

So what's the solution? Even more complexity on top of this ridiculous Rube Goldberg machine? All that to emulate solutions that already exist and already work well and vastly more efficiently?

Why?

Make the time. It’s worth it I promise. The freedom that comes with Linux is astonishing. I’ve been using it for a decade now and haven’t looked back. ‘If you want to move mountains you start by picking up small stones’
> if the mention is dishonest, then it necessarily follows that the author is dishonest.

Not really. If someone did something stupid it does not follow they are stupid. The same for evil, dishonest or irritating acts.

Though maybe "weird" would be better than "dishonest"? I posted in this form in comments on the original article.
> Yeah but the fragmentation is the problem.

Yes, exactly. It's the same problem all over, too - look at transport! You shouldn't ride a bike, you should drive a massive V8-powered 4x4 like I do. It meets my needs, so it must meet yours, right?
You are assuming curiosity was the problem instead of a lot of other possible factors like bandwidth.

I don't have a running narrative; there is some correlation probably with being left-handed and not having a strong internal narrative.

But I can let my thoughts out when I hand-write on paper but in a crowded room, I usually just stay quiet.
> If the entire field turn into toxic waste that no one wants to touch it will be extremely undervalued.

Bagholders will always try to find new victims. Crypto is praised even when it's in the shitter. "Buy the dip, it will be $200k before years end, I'd buy it myself but..." etc.
This is noise at best. I appreciate them trying -- how much can you actually change github to be a better product? This just feels like a manager or team creating work for themselves.
If the host has knowledge what matter is whether the host has the freedom to not open a second door (which they often have in TV shows where time is of the essence), and deprives you of a second round. If the host has this freedom, and he is adversarial and assumes you know the monty-hall paradox, then the only time where he will offer you to show a second door is if you have guessed right to make you change.
Accepted in what sense? Everyone I know who is involved with cryptocurrencies is so for “investment”, not for other kinds of usage.

Japan ceased all construction of nuclear reactors in response to Fukushima daiichi, and since that was a decade ago I'm betting that all the competence they built up has disappeared.

In other words, very similar to what happened in the US in response to Three Mile Island: after a scary nuclear incident there was a lengthy pause in nuclear construction which meant that all of the skills and learning-by-doing that had accumulated up to that point went away, and starting again would be significantly more expensive and subject to massive schedule and cost overruns.
You actually can turn them off. You can use mu-metal to short circuit the magnetic field.

https://en.wikipedia.org/wiki/Mu-metal
Well, not all at all. But there is so much desktop software going on the web and that is a good thing. You don't have to install it to use it and it doesn't need the performance and native capability of the bare metal.
This article is a rebuttal to a letter, that in his interpretation, claims:

>[...] that the entire technology field is worthless and cannot be used for any practical purpose.

However, instead of addressing the core issue of whether cryptocurrency or DLT serves any practical purpose, the article instead cherry-picks specific issues that he thinks are resolvable:

* Energy waste

* Transaction speed

* Privacy

The author seems to be missing the forest (that he himself identified) for the trees. Why doesn't he provide a real world use case for DLT? I'm still waiting for that.
Saying that cryptocurrency is widely accepted within cryptocurrency communities seems tautological. Meanwhile many attempts to force NFTs into games have been met with a lot of pushback from the "general" gaming public. I think it's fair to say that there's definitely a group of people for whom cryptocurrency is a "no way, no how" issue. Whether this group is large enough to justify the "widely" in "widely hated" is open to debate.
Such as? And are these features that GH already has in some capacity?
I would say record yourself speaking and then listen back to it. It will take a little bit of time to get over the discomfort of it, but you'll be happy you did once you get used to it. Not only will it improve your ability to speak, but it can also have added therapeutic benefits (not real medical advice :). The reason why this can be helpful is because you notice that, though it might feel like you are stammering while speaking, you are actually more eloquent than you realize. The small pauses are actually not that noticeable and you are already more coherent than you realize.
Personally, I find hand-writing useful but it seems like you've tried that already based on your comment history.
> If I just wanted to browse the web, and work in a terminal, then linux is great.

Or edit video, or make music, or write all the stuff that makes this possible.
I mean that's fair, but I'm talking about wanting to be curious and encouraging environments where curious individuals can be lauded instead of dismissed. Not everyone on a team HAS to be curious but for those that aren't they shouldn't be smacked upside the head with corporate bureaucracy.
So is “subverting the government” in Chinese one. (I suppose.)
There was a discussion about this a few days ago, and this comment thread [0] featured some criticism from experts on these claims.

I agree. I think the way the problem is often described and explained is terrible.

Why would the game show host want me to win? or want me to lose? What's his motivation behind giving me the option to switch? What knowledge does he have?
I guess these traces should depend on users network (location/latency/throughput/tor-enabled) and CPU. Did you use these as additional features for your model? Or was it a single configuration being tested?
> If you answer immediately, you will "ummmm uhhh" a lot. Learn to take a breather and buy time.

Not just in interviews (I don't interview that often), but just in general, I've trained myself to smile and say, "That is an interesting question!" (and subtle variants so I'm not a robot). It buys me a second or two if it's not that hard, and even more if it is a hard question because now they know I'm thinking about the answer and, well, that is okay.

Edit: And it often buys you points, so to speak, with the person asking.
While generally true, this is on income over 110K and you can get a US tax credit for foreign taxes payed.

It is strange that the US is one of the only countries in the world to tax citizens abroad.
THanks!!!!!!!! Yeee I love helping people - I like the suggestion on charging for profits - I definitely need to try that out next time :))

I'll probably write up a contract with explicit mentions of profits.

On mentoring - ye I have some nice friends and company founders - they're nice, but I just can't seem to synthesise myself to be better, so hence I'm asking on HN
A common way to explain this is to increase the number of doors.

You have 100 doors, select one blindly, and have a 1% chance of being correct.

The host removes all but one other door. Do you stay with the door you chose, a random guess of 100, or the one remaining after the host has removed all others? A door that is now statistically much more likely to be the correct choice?
> The problem is that threads just don’t work in practice for massive concurrency.

That's an assumption that is repeated very often recently, and measured very rarely. Truth is that they amount of applications for which they don't work is surprisingly low. I'm working at a well known cloud provider, and lots of people would really be suprised which applications at largest scale are working fine with a thread-per-request model. 50k OS threads are not really an issue on modern server hardware. While it might not be the most efficient [1], it will not perform so bad that it causes an availaiblity impact either.

There's obviously some exceptions to that [2] - but I encourage people to measure instead of making assumptions. Unless one finds themselves in a weekly meeting about server efficiency or scaling cliffs both models probably work.

[1] it really depends on the workload, but people might find an efficiency degradation (e.g. measured as BYTES_TRANSFERRED/CPU_CORES_USED) of 20% at a concurrency level of 1000, or maybe only at a concurrency level of 10k. Coarse-grained work items (e.g. send a large file to a socket) will show a lower degradation.

[2] Load balancers, CDN services, and e.g. chat applications which maintain a massive amount of mostly idle client connections can be such environments. They have a high amount of concurrency that needs to be managed, but less so of "active concurrency". If all clients would be active at the same time, those environments would run out of disk IO or network bandwidth far before CPU or memory become an issue.
> Someone should make a business out of selling them pre-flashed with valetudo for a less technical audience…

Please don't. Attracting a less technical audience to the project would be immensely harmful to it.
It is already quite difficult to deal with issues that technical people might have. You simply do not want everyone to use your open source project. There is also no point in doing so. Why would one want to make their own life harder?
What else does "host opens a door without prize" mean?
There is so much value in doing this in a normal application with a UI that lets you see what you're doing. ffmpeg is a fantastic utility if you already know what you need, but it's absolutely terrible for jobs where you need to be able to see and do things between the two states of "having input" and "having final output".
Check out Cloudready. I use it for leveraging the Google ecosystem.
Not trying to impress anyone, but I can see or think of an object, say a headset with cables wrapped around and color changing lights, and rotate it in any direction, even apply transformations. I've been exposed to a lot of 3D design, so I'm not sure if everbody can do the same?
Even if it would be 0% then it is still wasting energy and removing that consumption would reduce overall waste.

And "green" energy still have massive environmental and economical costs.
They weren’t slowing down ageing devices, only handsets that had degraded batteries. It’s an important distinction. The change that they made is now when your battery degrades you can choose to get peak performance at the risk of reboots.
You could use the ancient Microsoft logic questions. They are equivalent as easy. Leetcode is sticky for a reason even if it's not the intended reason.
Sure - but then it gets harder to exactly define the Mac Pro compared to the Studio (especially since right now the defining thing would be video cards, which isn't something that the M* processors really support yet).
Take the easy gig that pays better. Work on something in your spare time that scratches your itch.

Also, don't neglect your personal life. Mid 20s turns into mid 30s faster than you think. If you want a family there's a clock ticking. Either way, you ought to find something outside of work that will provide you long term fulfillment.
I agree that the customization is a huge draw for me.

But... I also want things like hibernate to just work, screen tearing to not happen on X11, etc etc.

The polish is absolutely not there, and I agree w/ the article that's a result of the fragmented ecosystem. If the Linux community could agree to invest in the underlying APIs for desktop stuff, it seems we'd be in a much better place and still have lots of customization options on top.

Of course, I understand that's a huge coordination challenge.
You forgot to mention: if you lose your keys, youre fucked. That is, of course unless you trust a centralized unregulated entity to manage them for you.

Some good examples by Elon Musk and Steve Jobs described in this article.

A small bit of nuance that could explain why the range could be $3.5 to $22 on a given day would be that they could be referring to different token types. The native token of ethereum (Ether) costs a fixed, smaller number of units of computation to send, whereas custom tokens (erc-20) have to do some additional bootstrapping work during transactions and cost more to send.

So there's the units of computation used x "gas price".

But yes, the "gas price" that serves to price congestion on the network is wildly variable due to congestion and low throughput. And that limited throughput is currently a real practical problem as you've pointed out in that the fees are too high.

The answer will likely be in L2s as other people are pointing out. I think one interesting side effect of this ecosystem is it is actually driving new research and application for cryptography (including substantial funding): for example practical uses of zero knowledge proofs.
Use the simplest sentence to answer, which is not a yes or no. And if you are the one that wants to lead the conversation, follow it up with a question.

But don't force the direction of the conversation, only follow-up with subject related questions.

If the interviewer is bothered because you are leading the conversation that is a job you want to avoid. At least as a person that is doing consulting work, that is what I would suggest.
The forum/mailing list format is over, most good discussions happen on discord now (some people swear by telegram - mostly Russians).

I'm not claiming it's a change for the better. I'm old enough to have caught the tail end of phpBB forums about every niche so I know what was lost. From a technical perspective forums are superior for long term discussions (especially for non-members!), but in terms where new stuff happens and where community forms - it's over. The closest replacement are specific channels on discord that allow sometimes for week-long discussions.

One of main social effects I see is that knowledge starts to get siloed. There are many technical details that exist online only on specific chats, which aren't google searchable. The main negative is that if you don't even know where to look or ask, it's way harder to figure out anything. There's also a positive: because people are forced to join they are more likely to contribute. In fact I have observed this in myself: often I only join some discord to look for one thing, but I just leave the server on afterwards. In many cases I see something worth responding to and morph from an observer into an active participant. This would never have happened on a forum. It's possible this factor is solely responsible for the current dominance of discord/telegram.

One future shift I can see is a move away from chats into VR. I don't think it's going to happen with zoomers, but alpha gen - assuming they grow up in VR spaces may find it natural to prefer literal talking as anime and furry avatars, with (almost) full nonverbal communication, instead of writing text messages to each other. In a way, it would be a return to the historical norm of human communication.

From a social trend perspective it's the same direction as the move away from forums into chats: worse information search (basically gone with VR). More emphasis on contributing and on personal relationships. The main disadvantage I can see is that it's going to place much stronger emphasis on people's characteristics: age, gender, native language.
> Mastercard and Visa charge a percentage (?!), Bitcoin is a fixed amount per transaction.

No, Bitcoin transaction fees are dynamic. https://bitinfocharts.com/comparison/bitcoin-transactionfees...
The truth is they’re completely irrelevant to 99% of the internet population. Pick the top 20 coins. Look at their respective block explorers and check tx/day, unique address/day, etc. You’ll quickly come to the conclusion that maybe 100M people actually use cryptocurrencies in any meaningful way. The internet has 5B users. Cryptocurrency use is irrelevant.

The cryptocurrency debate in technical circles reminds me of two extremely obscure religious sects screaming at each other while meanwhile the rest of the world doesn’t know either of them exists.
