I think using KJV is good for enhancing the joke though.
Having >2/3rds of validators (or >50% of power in PoW) let's you rewrite the chain back in history, censor txs, etc. You control what transactions go in blocks, and to a certain extent also recent history.
HOWEVER, this does not give you the power to steal or rewrite state as you please. You cannot convince the rest of the network that you now own someone else's ETH just because you have supermajority validator power. To take away ETH or change the cabin state in any other way, you need to include a valid and correctly signed transaction.
If you include an invalid state change (not caused by a successful and correct transaction) then all other nodes will reject that block, no matter how much validator power or hashing work went into it.
> The problem is at this point I have been on the team too long to ask any basic questions, one of the senior engineers even pointed out they shouldn't be helping me with certain processes at this point.
This is both mean and unhelpful. And possibly a sign that they don't realize how bad they are at training a junior.
I realize I'm a total armchair advisor here and what the hell do I know. But reading how this person approached potential customers I kept thinking "oh man I wonder what will happen when he talks to the insurance companies, why would they not be interested?"
I like it. Part of a good proof is a rigorous derivation. There is plenty of thing sto be said about what intuition can lead us towards such a proof. But at the end of the day, a good proof is ideally almost machine-checkable. Most proofs (much like code) lives two lives: the one in which they are written, and the one in which they are read. It should be almost trivial for a student to go back, on their own, days or weeks later, and see that each step is valid. And I think prose interspersed between column-style proofs do a better job than what margin notes do. The reason two columns work well is that the step and it's justification are of both condensed and almost always of similar length. Justification (much like code comments) may or may not need a good chunk of space. And surely nothing is stopping anyone from inserting little margin notes here and there in a two-colum proof, right?
I'd say odds are that the website is wrong, but you can always load those keys in a wallet and see if they give you control over the actual address.
If that works, I'd assume it's the case that some people have used weak keys (for example, a popular Ethereum wallet would actually generate 256 bits of entropy but accidentally truncate it to 32 bits in an operation), and any funds in those wallets will have been snagged long ago.
Point being: generate a private key properly, and no one will ever find it.
EDIT: I realize this is another page then the one I've seen previously, but I think the same idea applies. That one had support for Ethereum, too, and on the final page was an account with a balance.
The reason that we don't want the government to set minimum wages and benefits is because that's too crude a tool. The best trade-offs, sacrifices and share of spoils varies, and having the unions of different sectors negotiate with the employers (themselves usually organized in unions) is that you can optimize a lot more so that everyone wins.
And the bug wasn't really obvious, although the lack of input sanitation is something an auditor (given enough time) would probably point out.
I think the best way to think of it is that "WebAssembly" is a great marketing name, but what it does is be a modern-day JVM: a byte code language that can run anywhere.
Maybe it's not the most fail-safe way to get a good answer, but the article make it sound like the recruiters/interviewers are adverserial and have rehearsed talking points about shilling culture. If you can't get an honest answer from a recruiter to genuine questions, that's a red flag.
My main issue with the deathbed advice is exactly what he calls "hindsight bias". The deathbed advice is more of a wish-list -- it's not like they were thinking at the time "I should work harder" or "I don't live as my true self, and that's fine". I try to not work too hard, but I also try to make a good and meaningful career for myself. Do I just work less hard? I try to live as my authentic self, but looking back 5 years I see I was probably not doing, in a bunch of ways that seem obvious now but weren't at the time. I wish I had stayed in touch with some of my friends, but quite a few of them I'm happy I cut ties with.
I take no big offence with the advice in general. I think most people recognize that list as things that are sensible and lead to a higher-quality life. If these advice came from a generic life-coach, we'd shrug and say "good points, seems about right, easier said than done". But somehow, because they are "deathbed regrets" they get a veneer of sage-likeness.
Then again, here we are arguing about articles on Hacker News, so what the hell do we know about happiness?
Actually 1/3rd to disrupt consensus, and 2/3rds + 1 to take control of the chain like you could with a 51% attack on a PoW chain, only you'd get almost immediate and complete control over the consensus.
Generally, the best way to find bike routes in Japan (or most countries) is to ask Google for car directions and avoid highways and toll roads. But this time, it drove me straight into the radioactive danger zones of the old Fukushima plant. You were only allowed on those roads if you went by car, as a radiation shield. So I got stuck in a dead end, in a literal ghost town, trying to hitchhike. Man, I still remember the frustration and anger. Weird adventure.
I agree with the UX problem. I think the decentralized exchanges will manage to scale, research is ongoing. And the UX of decentralized exchanges is not much worse than/different from using Coinbase or Kraken, for example. The big UX challenge is self-custody of keys.
Also, wen stablecoins?
