Millions of people in third world countries have escaped hyperinflation by storing their wealth in bitcoin. The revolution has already happened. You see it as crime though, because revolutions are always criminal while they're happening.
In this life you can be selfish, stupid or a burden. Selfishness creates the most value in the world.
Solar is great in deserts, where the sun always shines and were the main use of electricity is air conditioning during the hottest parts of the day.

Solar is near-useless in colder areas, where you want to use the power for heating in the winter.

If you include the storage + grid expansion needed to compensate for the intermittent nature of most renewables (especially if you don't want to rely on fossil fuels when the wind is not blowing), the LCOE of many of them will be many times higher than just the production cost.

Meanwhile, Korea claims to be able to construct Nuclear capacity at prices down to $0.03/kwh with their APR1400 reactors:

That's at least an order of magnitude lower than the cost of renewables when constant output is required.

Operation Revive Coin
I know many poor country citizens who have had their families lifted into middle class even by american standards because companies were able to pay them in bitcoin whereas USD wasn't possible.

You aren't alone, though. There are many in their first-world bubble that don't see the benefits of crypto because their fiat fulfills all their needs. The same way you've never gone hungry, that doesn't mean food scarcity doesn't exist.
Well, I think a bigger issue is so many of the options not really mattering at all.
The correct phrasing then should be embezzlement.
> why do startups do leetcode too?

A point that I didn't see yet made. The truth is that lots (though of course not all) startup companies just have no idea what they are doing.

I had to deal with the complexities that imagined possible future scalability issues introduced into our stack when the whole customer base could be served by a raspberry pi, and it happened in multiple companies.

And it is not just infrastructure, but also code. I have to follow the twisted clean architecture rules and write tons of boilerplate code (that could make sense on the backend for a complex system) for a mobile app that is basically just a skin over a graphql API (basically no business logic on the client).

The same happens when hiring: we need top talent like FAANG companies do (but we can't pay for it), because we are awesome, where in reality anyone with a sceptical, product-focused mindset and a "get things done" attitude would do.

In my opinion this happens because we don't want to admit that our startups will likely not need the scalability for years, we won't need to follow fancy architecture patterns because our app is simple, and we could do well with developers who don't have top computer science skills.
Yeah you're so right about that. People my age will just pull up sport streams like it's just a regular simple thing. Often it's so easy that I've realized many people don't even realize it's an illegal stream. It's always such a sad state when you can get better quality, no blackouts, at no cost. The incentives are really in the favour of pirating.

Just like how I've gone back to pirating tv shows. It's just easier and more reliable. I don't want to hunt for where each tv show is on which network. Streaming is starting to feel no different than having to buy cable packages. It used to just be simple and cost effective to just have Netflix. But now each company got greedy and switched to exclusivity. Each with their own shitty video players.

I have Amazon Prime and have a better experience watching Amazon Exclusives via a downloaded file on Plex than I do using their player. Especially considering Amazon's service has ads that play mid tv show.

I guess a lot of this comes down to the same principle I mentioned in my original comment. Exclusivity is almost never a good thing for a customer. Whether it's streaming or ISPs that have a monopoly on internet infrastructure, it's never good for the customer.
If you'd prefer to donate using conventional currencies that is still quite available. I'm not sure if it really counts as a big positive when governments just incur additional overhead trying to process strange currencies instead of letting banks handle the exchange and just ending up with useful and liquid local currency.

And countries at war often use auctions of memorabilia or other objects to raise funds - selling an NFT is just a shift in medium.
I think the GP meant "still waiting" in the sense that they don't believe it will ever happen, not in the sense that they're optimistic.
Honestly I feel its the exact opposite. Anyone whose ever purchased a home or business should rightfully have cringed at the ~35% premium Musk is paying, and doubly so once he waved due diligence.

It seems like the people who are supporting this move assume Elon has some secret plan we're not privy too, but if so why would his actions be so erratic?
I'd like a physics analysis of how flat/hard a surface you need to roll a D65536, how long it would take to settle, and how good a microscope you'd need to read the top face.

Is there, like, 99designs for physics questions? I'd happily pay $99 for the answer, then post it here like I worked it out myself.
This is where projects should be more strict about operating (in some sense) as a DAO, with transparent voting and resourec/fund allocation based on proposals. Even if its a "centralized" single organization like Terra Labs or the Luna Foundation.

Seems silly to advocate for the future of finance and the trustless verifiable web, when the projects building on it still use traditional corporate mechanics and the veil to go along with it.

EDIT: DOA/DAO typo*
In the corporate world, "leaders" are incentivized by having more people in their orgs. It makes them have more "power". So they constantly broaden the scope and try to hire more people. The leaders in software orgs never benefit from finishing projects early with less engineers. Nor do they benefit from maintaining stable and robust software. Making the project take longer with more engineers with complicated architectures makes them gain more power. Yeah, this makes me sad.
Hmm, you are right. If the host chooses randomly, we get this tree:

- 1/3 it is behind your door

- 1 host picks a goat

- switching always loses -> 1/3 chance of losing

- 2/3 it is behind one of the other two doors

- 1/2 host picks the goat

- switching wins always -> 2/3 * 1/2 = 1/3 chance of winning

- 1/2 host picks the prize

- result undefined -> 1/3 chance of ending up here

So you get 1/3 wins, 1/3 losses, 1/3 undefined. So given the goat is revealed, you have a 1/2 chance to win by switching.

On reflection, this makes sense. The host is indeed leaking information by not be able to pick the around the prize. If the prize is not behind your door, his choice is constrained. So his revealing it supplies information about that constraint. If he is not constrained, then you are both picking doors at random. I'm sold.
If this was happening as often on Volvos or GM vehicles don’t you think they would be looking into it too?
> The problem with Windows or Mac isn't that it looks, feels and works the same everywhere.

Did you use Win 10 ? One GUI in Teams, another in Office 365, a calculator which comes from outher space, 2 interfaces for configuration, disable microfon for admin account -> no microfone for user account.
What are the use cases for these buzzwords? I've been waiting a decade for solid models to emerge.
I don't know, this seems like it was a pure CPU problem on good hardware. But anyway a developer who has 10 hour days and backlog stretching beyond the horizon will not have idle time to go try things out. It needs to be someone's explicit job to go hunt down things like this.

And given it was data-size dependent, I wouldn't be surprised this was not an issue at the start while someone who's job it was to look for this kind of issue was looking. And the issue appeared after they got retasked to something else.

In fact maybe this is the only kind of issue that you end up with after all is said and done. Just like in WW2 they reinforced the parts of the fuselage on returning fighter craft without bullet holes, because if a bullet hit there, the craft would not return.
Lots of good advice here. One important one is not to be afraid to pause* and think. Someone asks you a question and of course you want to answer right away to be responsive, enthusiastic, and all the other things people correctly tell you to be which are all swirling in your head.

So the interviewer asks you "I see you're a Java programmer: what are the most common library datastructures you use?" You could easily jump into "Yes, I have a lot of java experience, having worked on X and Y, and once I had to implement a custom hashmap because we had some unusual constraints blah blah". Just take a second to make sure you are answering the question actually asked: "Well in my Java code it sometimes feels like the only datastructure is ArrayList! Which is funny because when I write Python code I predominantly use maps".

This is good when you have some pre-planned answers (as has been suggested elsewhere) to make sure you use the right one. Also good when you have to think up the right answer: when you know what you want to say you can concentrate on saying it.

This problem affects those interviewing in their native language as well as those not in their native language, as with you. Everybody is nervous.

Couple months back a seemingly talented promising colleague quit for croinspace.

He had some arguments like "I don't want to pay taxes so gov blocked my accounts, it's an unfair system" and "it's a scammy field now, but we can solve that by simply automating scam assessment".

When I talked to his superior turned out he shown himself not nearly as good a dev as my impression was, they were strapped for resources yet not sad to see him go. Makes me think it's not usually the best brain power that goes there.

Knock the egg’s “butt” gently against a hard surface. You want to crack and smash the outer shell, but not break the inner skin. A small, bean sized area is enough. Then, boil it. The cracks allow water and steam to get in between the egg and the shell. You’ll never again have to deal with egg sticking to the shell while peeling.

Twitter has been calling Elon's bluffs since the start of this entire episode.
There is not enough financing in place to buy twitter and they both know that but Elon can't just say he's not rich enough. Instead twitter accepted his bid knowing full well that the deal will fall through (and pocket 1B in the process).
Unlikely; they're quite careful in their wording. From their latest annual report: https://s22.q4cdn.com/826641620/files/doc_financials/2021/ar...

> We estimate that the average of false or spam accounts during the fourth quarter of 2021 continued to represent fewer than 5% of our mDAU during the quarter. However, this estimate is based on an internal review of a sample of accounts and we apply significant judgment in making this determination. As such, our estimation of false or spam accounts may not accurately represent the actual number of such accounts, and the actual number of false or spam accounts could be higher than we have currently estimated.
Also I want to add a somewhat representative anecdote story.

Preface - my corp issues same laptops to all engineers, including developers actually writing code. Codebase is 100% for Linux, we don't need write anything Windows related. Developers have complete freedom at what to use as a host system on the laptop, there are some guides to help set up host Linux, there are people who already did it and can give advise.

Around half of them just opt to host Windows 10 and run all their tools in the Linux virtual machine. That's a group of people who are second in world most suited to run Linux - actual Linux application devs. (first group would be Linux admins I think)

I used opera as main browser from Opera 5 to Opera 10. Use to have Opera mini on my J2ME phone as well. With every new version, the stack of bugs from previous versions was piling up and features were being reduced or getting lost to bugs. There were bugs in mouse gestures which was my main way to navigate Opera. Stopped using it when Chrome came.

If you remember, at some point Opera even use to ship custom build for you. With name or custom title or something, don't remember the exact customization.

My most used utility in Opera use to be notes and irc client which I used to ask questions basically. Never used mail though.
Vivaldi promise features at the cost of performance. I have tried to use it 2 or 3 times. It feels sluggish, every click feels late. Can't use all the packed in features like that. Opera was always fast, Vivaldi is just not.

There was no false information provided by Twitter /because he waived due diligence/.

> Musk waived due diligence when he moved to buy the company, seemingly to hasten the acceptance of his bid.

> He wrote in a letter to Twitter Chairman Bret Taylor on April 24, "As we discussed, $54.20 has been and will remain my best and final offer, period. This is binary – my offer will either be accepted or I will exit my position."

> Twitter announced the company had accepted his offer the next day.

> But in the weeks that followed, Musk vocally criticized Twitter during media interviews and on Twitter, where he has tens of millions of followers.
Do you transribe it by hand? Or via software?
Well, during decommissioning that would be a tricky thing to do, but during maintenance I could image a way to slide the mu metal in front of the magnets shunting the field away in a safe way. But you are right, working on such gear requires strict precautions and attention to safety detail.

Let me give you one example of how hard it is to work with these: while building the windmill I had decided on an 'inside out' model where the rotor rotates around the stator, this has a bunch interesting properties, such as pushing the magnets onto the drump while they rotate instead of trying to eject them from the rotor in the normal designs. And because magnets get hot any kind of glue or other adhesive would be subject to all kinds of thermal stresses, might let go or melt. So that was a pretty neat solution. My rig for installing the drum was a half ton crane over a very heavy steel workbench that had the stator mounted to it.

As I lowered the rotor suddenly the whole assembly, table and all lifted off the ground and perfectly centered itself around the rotor. I swear I never ever saw that one coming and it really scared the crap out of me because only minutes before then I was still fiddling with pushing some wires in place inside the stator while the rotor was already floating above it. A bit earlier and I could have easily gotten pinched, in spite of all my precautions.

> - Noisy neighbor problems from other threads messing with your TLB and L1 cache

Switching between threads within the same process doesn't require a TLB or L1 cache flush. Not sure if you were implying this, just wanted to point that out.

> - High cost of context switches

Userspace schedulers (like rust's tokio) do make context switching cheaper, however, most of the context switching in the case of a web server is due to blocking I/O and the most expensive part of the switch, entering the kernel, is already accounted for by the I/O request. Kernel context switching is unlikely to be your bottleneck.

> Unpredictable scheduling/priority inversion in the scheduler

This can definitely be an issue at scale, but a general purpose async scheduler like most use is unlikely to be any better.
I'm pretty sure most people saying Yes or No to this don't have the information or legal background to actually give that answer.

> horrible people

When someone calls an entire population of a state, nation, or region as "horrible people"; we call them bigots. It is time for introspection and reflection when you get to a point where everyone you don't agree with are horrible people. And it is not even true, most cities in Florida are democrats, but IMO that shouldn't matter.

Usually this would be flagged, but it goes with the party lines I suppose so it is allowed.
In addition to other good suggestions here, make sure you get enough sleep. Lack of sleep reduces my speech to idiot level.

The same goes for food, exercise, keeping yourself healthy in general. I find sleep to be the one that has outsize and immediate effects.

Let's be honest, the vast majority of things we spend money on is a complete waste, focused solely on producing short-term feel-good chemicals in our brain.

Tasty food? Waste.

Fine wine? Waste.

Any car that costs more than $20k? Waste.

Blockbuster hollywood movies? Waste.

Housing that goes beyond our basic need for shelter? Waste.

The resources we've spent on crypto are, at the very least, pushing technological frontiers. And experimenting with new systems of finance that could improve on the foundations of our entire economy. Compared to all the other crap we spend money on, this is far less wasteful.
This notion that every bad decision made by a billionaire is a strategic chest move where they come out on top, is odd.

This is silly. Musk will produce evidence that a material fraction of tweets are fake. Everybody knows it's actually true, and even if his evidence isn't as compelling as advertised, it will still probably achieve what he wants -- which is the ability to force Twitter to negotiate a lower price.

I guess I am the anomaly. I like being the office! Working at home is great too. But the office offers a mental refresh that I can’t replicate elsewhere - working with/talking to people about my day-to-day with all of the nuance that comes with in-person communication. I know I can go for walks, or garden, or use my own bathroom, but there is something zen about taking the train to work (suburb to NYC) to feel the energy of the city and the office, even if it isn’t jam packed with people.
What EU country are you from where someone would be confused by another saying a proposed EU law is "unconstitutional" in the native language?
