Thanks! Could super conductors help increase efficiency or density? Why or why not?

Could this be a viable space to launch a start up? With launch costs coming down there could be a lot of demand for more efficient thrusters.
> Again, what solutions?

I am talking about actual concrete solutions. “Do this code change and the bottleneck will go away”.

This person offered ACTUAL CONCRETE SOLUTIONS to performance issues. He literally opened bug-tickets and discussed with the team, and provided proof-of-concepts, but a FAANG manager attempted to shut him down.

This is not some snake oil salesman offering magic performance beans, this is someone who actually knew what they were talking about, and was able to diagnose performance problems in the operating system and solve it, for free. This isn’t some hypothetical, he REALLY did fix it despite being told it was impossible.

EDIT: Like the sibling poster said, the systemic solution is to "git gut". Which is clearly impossible as long as developers and managers foster a culture of dismissing performance, or in some cases inventing excuses not to work on it, as was seen in the Casey/Microsoft debacle.

But it's not actual money? The NFTs space seems to just be an extension of the old art appraisal scam: the asset can have whatever value happens to be convenient at a given time.
Biking also made me realize just how incredibly useful cars are, which completely explains why cities are willing to spend so much money effort and space for them.

I've tried biking walking public transportation, cars are just better. I still bike for certain trips, but it's limited in usefulness.

Yes agreed. Some countries and cities had better taxi service than others. But one of beauties of early day Uber was that I was able to use the same app globally (in the US, Taiwan, and even Chiba) and it used my prexisting saved credit cards even! No fumbling for the local currency, registering a local payment method, or worrying if I am going to be scammed by the driver—just a consistent note global taxi hailing experience.
No, the same doesn't apply because the payment gateway probably has terms of service and specific laws protecting it. It's protected by those laws.

Cryptocurrencies claim to be something else. Something that isn't government by terms of service, laws, etc. How else could you create a worldwide decentralized currency without adopting a rule that code is law.
> The stock market is a system that enables the buying and selling of shares in productive business

Ostensibly, yes. But in practice stocks are often pretty disconnected from business realities by algorithmic trading and high-frequency trading. Even manual trades made on a snap basis like a mass sales on a company posting a slightly less than stellar quarter on the back of a proven long-term, solid, growing business: is that company really "worth" 10% less today? Especially since that "value" is then often recouped even before the next quarterly report.

Most companies can't even explain many of their own stock price moves.
While what you say makes sense, the only solution is if people start calling out politicians within their party. Criticizing the other party doesn't promote internal change.
How so? How is being able to vote or not influencing people being informed or not? (which, by the way, is absolutely not what I was talking about in my previous comment)

Having voted before does not make you a better voter in the future. I don't think the fact that I had to wait with my first vote for almost full voting cycle longer because there were elections right before my 18th birthday that I couldn't take part in had influenced my political stances in any way.
I think a big factor is recovery time. When you’re young you can do some extreme activity and still be well rested the next day. Recovery time even for fit people just gets a bit slower when older. But if you’re not pushing yourself then you can usually recover fully by the next day.
Thanks for the link suggestion.
Yeah, I've already checked several things in Python and it seems similar. I'm a bit worried about the differences in implementing different design patterns for example. So not really the basics like variables, loops, modules etc.
Applying the incompleteness theorem wouldn't say that every piece of complex code has unpredictable outcomes, but that there exists some pieces of code that have unpredictable outcome.

Ethereum's revenue is the transaction fees it collects for people to use the network. Its expenses are the rewards it pays out to miners and stakers. Its profit is the difference between the collected fees and rewarded fees.

This difference between collected fees and rewarded fees is "burned", or ceases to exist. The process shares some similarities with stock buybacks.

> or is it?

That's the question, isn't it? We're being told that it is. We're told that 42 out of 54 rejected math books "incorporate prohibited topics or unsolicited strategies, including CRT." Of those 42 books, how many included CRT and not some other "prohibited topic" or "unsolicited strategy"? Doesn't say. What does an example of a math book including CRT even look like? Doesn't say.

And as much as I agree with your aside... this was done by the Florida Department of Education and textbook review is within their mandate and abusive policing is not. While I wish it wasn't a partisan issue, it seems that everything is a partisan issue these days, even chicken sandwiches.
Because real world assets already have frameworks governing their ownership, and those frameworks generally do not take NFTs into account. If the NFT actually grants you ownership of something tangible (like stock, IP, real estate, etc.) then to make that legally enforceable you need to also sign a traditional contract which makes the NFT pretty pointless.

If I bought your house and in addition to all the legal paperwork you also gave me a handwritten note saying "house is yours now, promise!" do you think I'll care about the handwritten note? If you only gave me the note and not all the normally required paperwork do you think I'd pay you?
I use alarms on multiple devices to maintain a strict 7 days schedule.

For me, a 2:30am to 7:30pm local time wake schedule allows direct daily communication in all important time zones; it has the added advantages of allowing for decent morning rituals and a solid 4 hours before anyone local is online, and eliminating the typical activities most people engage in after 8pm..

Along the same lines, I start my personal weekly schedule on Friday mornings with the aim of preemption of Friday afternoon crises and preparation for whatever looks likely to come along the following Monday.

My experience is that any schedule allowing for less than 8 hours sleep time needs vigilant protection of the time one actually goes to bed to avoid sleep deficit.

The issue is really whether people are aware of their own biases and actively try to counter them by trying to look at events through the lens of different biases, or just run with their own biases because they're trying to promote them, generally with ulterior motives in mind.

Hence George Orwell: "Those who control the present control the past, and those who control the past control the future."

I studied for the interview I wanted (by being a thoughtful software engineer in my day job) and not for the interview they offered (which would require me to either be a professional leetcoder or some algo/performance expert). If they didn’t want a good software engineer then they’d have to pass on me. I made it clear in every session that I was thinking through the problem, asked good questions, and when there were aspects I could write concrete code for I did. If you score by solution competence and performance I think I aced 2 of the coding sessions and did pretty mediocre in the other 2. My interviewers must have been willing to go a bit off of the default mode of operation as I managed to get an offer.

I don’t know if interview performance has anything to do with negotiating power, but I was able to get damn near the highest possible total compensation my level allows for without a competing offer.
It doesn't have anything to do with C/C++ support: .NET strings have never been null terminated C-style strings, they've always been Length encoded, garbage-collected strings and have always needed to be marshalled/converted to/from C-style strings no matter how "raw" bytecode you get.

It is possible to do unsafe pointer manipulation in the CLR, but using that for string manipulation was always a bad idea (too easy to fall into bad UCS-2 assumptions that don't apply to UTF-16), and in modern .NET not only is it the wrong approach but Span<T> and Rune APIs provide a much friendlier and better way to do it without unsafe pointer manipulation.

You are correct that there probably is more bad code using unsafe CLR pointer access for string manipulation in the wild than should probably exist in .NET and ever existed in the JVM, but .NET has made breaking changes to unsafe code before (.NET Framework 1 to .NET Framework 2 involved quite a few; it may be long ago in memory, but modern .NET transitions have been closer to that 1 to 2 transition than not; already gone are the days of .NET Framework 2 to 4.x where they were afraid to make low level breaking changes because the Framework was bundled with Windows).

The difference is that JavaScript is an interpreted language, rather than a compiled language.

Interpreted languages are distributed as source code, and an interpreter evaluates each line of code to transform it into machine language for execution on the CPU. This allows the same code to run on any CPU for which an interpreter is available.

Compiled language source is transformed into machine language once, at compile time, using a compiler that understands how to turn the source code into machine language for a given environment. Once it's been compiled it generally will only work on the CPU/OS for which it was compiled. If you're going to distribute the work, you will have to compile many different versions.

There are volumes written on the differences and advantages of each method. JavaScript was created as an interpreted language so that developers could write code which can be executed on any browser with a JavaScript interpreter- important for a language that is used on web pages which can be viewed on a very wide variety of devices and machine architectures.

Well for one thing you're also subsidising ('subsidising') all the people who earn less and pay less tax than you; not to mention all the people who are net paid by taxes.

I've never lived in the US and I do hear that perhaps it isn't particularly efficient with tax money, but still, if you looked at the average tax paid instead of your own it might not be nearly so amazing?

Detailed analysis: https://scribe.rip/@omniscia.io/beanstalk-farms-post-mortem-...

TL;DR: Beanstalk violated several commonly known best-practices and are now suffering the consequences. This kind of economic vulnerability can barely be called an attack - certainly does not clarify as a "hack" and it's several years since the community learned from bzx and similar almost identical incidents what happens when you make irreversible decisions based on on-chain price oracles like Curve (which is jot the fault of Curve - they should just not be used this way!)

Hopefully the FBI recognizes this. If anything, Beanstalk promoters are responsible for irresponsible marketing and shifting blame.

> The lightning hostile takeover raises fresh questions about the unregulated nature of digital currencies and the lack of protections for investors.

No it doesn't. It's quite clear that there weren't any protection mechanisms at all. The kind of investors who put funds into contracts that can have those funds transferred out at the whim of a threshold of governance votes that are tradable on the public market must be aware of these risks - in particular sine it's the umpteenth time that in principle identical scenarios have played out over several years now.
This isn't even a loophole.

Beanstalk apparently set up what amounts to staking system for votes. More money == more votes. Have enough money? Well, then you have the majority of votes and can do whatever you want.

This is precisely how the system was designed to work. They just didn't foresee someone building up a large enough stake to amass the voting power needed to undermine the system. And that is simply a failure of imagination and goes to show how naive these folks were.

The way this works in the real world is you have a limited number of shares that give individuals some number of votes, and those shares change hands. In order to build up a large enough position to control a company, you have to convince existing owners to give up their stake or vote with you.

But if every dollar contributed to a "silo" creates a new vote, then yeah, you're basically saying: If you're rich enough you can take control of the project by simply amassing a large enough fortune in the project.

There's probably things they could've done to reduce the likelihood of an event like this--e.g. requiring supermajority or unanimous voting for certain types of changes, for example--but they didn't, so here we are. The system worked as intended.

And yes, I really mean "intended". They intended for people with more money to have more of a voice. And this is the (extremely obvious) consequence of that choice.
It's also important to note, I think especially in this context, that this framework isn't really a matter of ideology. I'm not saying you think it is, but I think a fair number of people here are likely to interpret it that way. This view is so widespread because people who practice history find it valuable.

When you come across, for example, a widely known primary document that contradicts or undermines a view common to historians for many years, how do you explain that? The answer isn't in the facts of the documents, it's in the social construction of "history."

I think there's a really common implicit assumption that historians are just people who know a lot of things about history. But once you get away from that and into the understanding of it as a skill- and research-based social practice, you start to need something to explain why we know what we know, or think we do. This ends up being a fairly useful one!

Journalists used to say they they would need two independent sources that corroborated each other before they went with a story of note.

These days, two anonymous tweets "are corroborating sources" for them. It's such a joke of a profession, with a few exceptions where there is in-depth vetted reporting, but those are anomalous these days and not representative of the profession, to the detriment of society.
Putting any Google service connected to your account as a recovery method for your Google account seems like a problem to me. I don't know why the author didn't get any alternative recovery options if they had those configured like they said, but this is a good reason to only enter external services as any kind of contact or recovery mechanism.

Worryingly, after the whole ordeal the author still seems to choose to rely on their Google account now as much as before this all happened. It's kind of a miracle they got through to Google in the first place and it definitely won't happen again; it worries me that this post doesn't end with "and that's why I split my life across separate dedicated services". It feels like the author learned This One Cool Trick instead of the underlying lesson, which is that Google (or Apple, or Microsoft, or any big provider) cannot be trusted to not randomly cut you off without warning.
Or "what is your name"? Seems like spam is always trying to hide the actual identity of the sender. "This is Jack from the warranty department"? Yeah, sure you are. Whose warranty department? They won't get specific because they know that if they do, I'll know that I don't know these people. They're trying to pretend that they're someone that I already have a relationship with, but in doing so they get vague.

And, "The vehicle warranty is about to expire"? Yeah, which vehicle? They won't get specific because they don't know.

I don't know how to implement it, but a "who are you specifically?" filter would eliminate a lot of my phone spam.
