Genuine question: why nuclear over mass solar? Panels on every house, decentralized, etc.

I was having a discussion with a friend recently about this and he was very much pro-solar and thought nuclear wasn't the right way to go from a cost/centralization perspective. Figured smart people here might be able to color this a bit better.

-edit-

Ty to everyone who responded here. It's enjoying to read these different perspectives.
The big problem with older reactors is that they need active cooling for awhile after they are shut down.

That's why Fukushima exploded. The diesel generators flooded and couldn't run the cooling pumps. Chernobyl happened during an experiment shutting down the plant using the momentum in the generator to cool the plant.

Newer reactor designs can shut down safely without active cooling.
> I disagree with this. As an example, a video came out the other day of a Chicago Transit Authority employee getting into an altercation with some guy. "Some guy" pushed him to the ground and walked away. The employee very slowly (he was quite obese) rose to his feet, pulled a gun, walked after the guy, and then shot 14 times hitting him 3 times. In short, he murdered the guy on video in the middle of a crowded station. There's no way that's not irrational behavior.

"If someone seems irrational, it's because you don't understand the person"
"Thats not true, because I didn't understand why somebody did something, so he must be irrational."

IDK if you know what circular reasoning is, but you're suffering from it.

The video in your example doesn't fully explain the situation. You don't know these people, you don't know what happened before, you don't know if they know each other, you don't know what the other guy said/etc.

I personally don't know what the circumstances are, but I do at least admit, that in the infinite amount of possible circumstances there are at least a couple which allow for a sane/rational person to shoot somebody in broad daylight.

> There's no way that's not irrational behavior.

There's a book called 'Thinking fast & slow' that talks about questions like these. "Is someone's behavior rational?", is a very hard question to answer for your brain, unanswerable even. Still your brain quickly comes up with an answer: 'it's irrational', disregarding the fact that this by itself might arguably be irrational, how does the brain do this? What is this answer based on exactly?

To answer hard questions quickly like that, your brain has a trick: it doesn't actually answer THAT question, but secretly gives the answer to a different question, that merely looks a lot like the original question. In this case, I suspect your brain is actually answering: "If I had an altercation on a crowded station, and somebody pushes me to the ground, WOULD I slowly get up, draw a gun, and shoot the guy 14 times?" The answer is no, so the 'answer' to the question is this guy being rational is also 'no'.

So basically your brain is transplanting your own experience, your own set of learned behavior, yourself, into the situation that you saw in the video, and then decides: "Well, I wouldn't do that, so conclusion: this guy is crazy". But ofcourse out of all the possible upbringings, experiences, lifes you could have, you only have 1. So you will never truly know how it is to be someone else.

The only way to know if the shooter in your video was rational or not, is to ask why he did it.
There is also the alignment of schedules requirement for meetings, especially at higher levels. 8 hrs of productive work may not be required but calendar availability is to a certain extent, especially for higher-level roles.
Are there really that many kids getting perfect scores?

I got a pretty low/average score, but took the test early in junior year so I hadn't taken some of the more advanced math courses yet. I never took it again since I got into everywhere I applied to (didn't apply to ivy league, obviously). Seemed like most other kids I knew did similarly with the smartest kids maybe 150 points higher (2400 time-frame). Nobody I know got a perfect score, or even close to it.

Edit: man, after talking about this I want to see what my score was exactly. No way am I paying $30 for an archived score though. I want to say it was only 1200/1600 (the schools only wanted 2 of the sections). But I'm not sure I trust my memory for something so inconsequential from that long ago.

Extra edit: found my old score report. It's worse than I thought. The writing was 570 (74th percentile) and math was 510 (47th percentile). I'm a lot dumber than I remember.
Simple honest answer is any compiled language will likely beat it. Your big ones being C, C++, Go and Rust. I personally despise Go but it does categorically run faster than PHP so is a valid answer here. However there’s a ton of other compiled languages based on GCC and LLVM and many of them will likely have a web framework or two.

I’d personally recommend Rust if only for for better integration with the Erlang/Elixir ecosystem which is the other super powerful language that can be a real secret weapon in terms of scaling performance once you need more than a single hardware mode.
The extra $595 a year is paying someone else to run the infrastructure and security updates.
> Windows probably has at least one person dedicated to making battery life better

I think that person works for the hardware manufacturer, and wrote the Windows driver. I think that the likely problem here is that "Linux certified" just means that there are no showstopping bugs, "equal battery life to Windows" isn't a metric anyone is shooting for. I keep hoping that someone (maybe System 76 of Valve?) will take Linux hardware support REALLY seriously and get show what can be done.
I can't comment on law, but back when I took the SAT and ACT (granted, it was a previous millenium) you could retake the test. The issue was, unless you were sick or otherwise in an abnormal state, you would usually get a pretty similar score the second time. They provide a few examples of old tests, so you know going in what your score is likely to be, thus you will know if it is likely to improve much if you take it again.
Hitchens was brilliant. Very unfortunate that he passed away.

I wonder how he would take current events of today. He was a democratic socialist yet quite unlike Bernie Sanders. libertarian is oh so many ways.

he was pro-iraq and afghan war. Anti israel. Pro-life, anti-death penalty, pro-gun, end prohibition on all drugs, definite trans rights = human rights.

By todays standards he's a mix of left and right wing; yet if you listen to him he's very intelligent and eloquent.

Makes me wonder what he would think of characters like Trump and what he thinks we should do for Ukraine.

I totally forgot about the peace dividend. In a way humanity was hoping the economic sanctions against Russia would work. Obviously they didnt.

If the sanctions did work and russia, a nuclear G7 economy, was forced to end the war. It would make it clear to humanity that we are post-war. Anyone else waging war or even considering invading a neighbour would have to consider similar sanctions.

Unfortunately countries like India and China continued trade with Russia and enabled war to continue.

Unfortunately that means the only thing properly preventing war are nuclear bombs. Russia breaking their treaty of non-aggression with ukraine that was established by giving their nukes to Russia just told the world that was a bad decision. It just told the world that sanctions arent enough, that humanity will still live with the reality of war. That keeping nukes in reserve is the only way

What a disaster.

You're discounting the stories of all the people in those communities who dies of TB. It's indicative of the similar problem of vaccine hesitance - everyone remembers their grandparents living, and not the 2-3 great uncles/aunts who died before they bore children.

There'd probably be a lot less bad faith interpretation if it didn't end with a double-zinger of 'And once you reduce your life to a neo-liberal economic model, is when you will finally grow up and become an adult'.

That last part in particular poisons the rest. Sure, it could be interpreted in good faith, but as it's so damn condescending - why put the work in?
That's a great point. However, you're using the idiom of the tail wagging the dog incorrectly. The tail wagging the dog usually means something important or influential being controlled by something less so. In other words, the tail would be wagging the dog if I wrote a blog post that made people change their opinions on the SAT.
It's not clear at all that the founder had any understanding, beyond the most basic, of the market they were entering. You don't have to start out with a path to monetizing a business -- but if you don't understand the possibilities that you're opening up for yourself, then the odds of success go way down.

Once money was desperately needed...the response was to cold call small doctors offices? That, clearly, shows the deep lack of understanding of the market for this type of product.
Honestly every educated adult should understand calculus, and certainly anyone with a technical degree should. Sure many people will be unlikely to need to do the raw computation of calculating derivatives and integrals (even people doing machine learning are typically letting computers do that work), but to understand the way these two concepts work together and describe the world is really essential to understanding so many problems.
> transferring reputation ... between contexts

The problem is, the systems we have today don't put walls between contexts but between implementations.

If someone is a famous actor, and they have millions of followers on Twitter, then they can tweet out some hot take on vaccines and all their followers will see that. However, if a scientist has a lot of followers on Twitter, but wants to move their account over to Mastodon, they have to start from scratch and lose their audience.

Is there such a pushback? As in, is the percentage of the workforce refusing to take such tests increasing?

It is extremely expensive to get significant amount of energy from roof mounted solar. Solar doesn’t shine all of the time. Storage is extremely hard. Japan does not have a lot of wastelands to spare on mass solar power farms.

Nuclear, on the other hand, just works, 24/7.
Small scale nuclear reactors (and microreactors) would be a solution to that centralization problem. I know that NuScale had some controversy a couple years ago; not sure how that shook out. Whether that design should be modified or not, in theory there's nothing stopping reactors generating community-level power, except that nobody wants a reactor in their back yard. Not saying anyone would want a coal plant in their backyard either, but given the choice it seems like they'd choose the coal because it scares them less while hurting them more. I hate to say it, but it does really does seem to come down to dealing with irrational fear a lot of the time.
I have heard about this, but I coudn't find a license on their github page. Do you have a link for it?
Yeah no the study was definitely not about test prep getting people from 2370 to 2400 lmao. There is no test prep service in the world that will claim they can get you from a 2370 - 2400.

The mean SAT score is ~1600, so it's a 30 point increase for students scoring in that range.

If you're already capable of getting a 2350+, that means you know everything and it's just down to variance and not making a silly mistake.

A perfect 2400 score is actually really rare. From a stat in 2009, the collegeboard reported that 1 student out of every 5,000 taking the SAT gets a 2400.
I would argue that calculus is essential in discrete maths, but ML is not essential in Computer Science.

I absolutely respect and appreciate that the game wasn't trying to be "fun"; it was trying to communicate a message. And I firmly believe that not all games should be fun.

But at the same time... well, I have enough work to do in my life. There has to be a balance. Not every movie is "fun" but even art house films are generally "pleasant" to watch on some level.
> You are the boss of a company of one. Your company sells labor to the labor market, it makes investments in assets, it borrows funds, etc.
It’s your job to decide how that company is run. It’s your job to decide what investments that company needs to make to get good returns.

> It’s also your job to interpret the contracts your company enters into and decide what is acceptable, and to appropriately risk-manage legal hazard, reputational hazard, etc.

This is an argument that you have the responsibility alone to optimise your behaviour in the market. Yes, your utility function could be oriented towards something other than profit, but OP specifically oriented their argument towards getting "good returns".

While this is the direction that neoliberal capitalism pushes you in, what with the social alienation and commodification of everything in life, but that's because it's not aligned with human wellbeing. Your self-image should not be one of a company optimising its market behaviour; this precludes socialising, spending time in nature, exercising for reasons beyond increased economic productivity. It reduces human existence down to rational behaviour in a market.

To present an alternative, because criticism in a vacuum isn't very effective: I personally think that you should optimise your involvement in the economy, so that you are minimally involved in the economy, so that you can spend your precious little time on earth doing things that actually matter to you - whether that's social relationships, hobbies, communities, whatever. The market is something to be avoided, not exploited. To do this effectively you have to understand the market, sure, but it's the same way an accountant for an enterprise company has to deeply understand tax law in order to avoid paying taxes.

If that's also what OP was arguing for then that's a whole other thing, but that's not the impression I got at all with the whole "you are a company, start acting like one" spiel.
btw. i'm not claiming Next.js and Gatsby are misadvertising themselves, but instead i see lots of people categorising both frameworks as such, which is wrong

100%! As a parent of a child about to go through the college admissions process (with his heart set on MIT--of course), I want him to read this particularly for the later part of the article: "...you are also not your MIT application..." The acceptance rate is so low, that it should not be used as a measure of self-worth and accomplishment.
And many people know Americans who were attacked with a knife or gun one day and never return home.

At the end of the day you never know what's going to happen. Even in Cleveland OH, my bike got a flat in a neighborhood full of people of a different ethnicity as me, and as soon as the locals saw I would have a harder time getting away, the predators came out to try to rob me. On the flipside living in rural phillipines, a guy approached me menacingly with 2 machetes and when I just smiled like I was happy to see him, he invited me to eat the dog he was cooking over an open fire. Life is full of surprises, and these kind of things happen everywhere.

Anecdotally I also know a rural villager who was attacked by machete by a fellow villager in this fashion, and when he fought back it never happened again. I'm sure being an outsider was part of the attack, but that may have just been prison rules for the area to see if you'll stand your ground.
I'm not sure if this is a new trend, or if I've only just begun noticing it over the last decade. People seem to have completely lost the ability to infer the meaning of words if it lies beyond face value. What a trite, shallow interpretation.
Just curious, do you have any other recommendations that are more or less timeless?
So I wonder if "using fewer GPU calls" is the solution to Linux's battery problems, or if you've just found a parallel way to cut battery usage that counteracts it...
Nuclear doesn't require batteries for overnight power. It's an energy dense, clean process, where the primary externality is some nuclear waste.
Calculus is not just about gradients. Fundamentally, calculus is about calculation and symbolic logic, a much older concept that predates its usage in gradient-based machine learning. In this sense, calculus holds deep connections to logical reasoning, proof theory and the foundations of computer science. [1]

Re: Earn out.

1. My understanding is the earn out was discussed upfront, so not a reason to back out of a LOI.

2. I've been through an acquisition (different circumstances). IMO 1 year is critical to a good transition and honestly, weird but fun. Year 2 the main integration stuff is done, and you should be out, so things start to get akward. Year 3 you probably shouldn't be involved, you want the business to be sustainable on its own. Situations vary, but I think all parties would be better off with a "1 year full time then 1 hour/week for another 2 years." 1 hour/week should be easy to give, even if you take another gig, and is enough time to help continuity.
i feel like it's something that, on its own isn't worth much, but could be sold to a group like goodrx or webmd or something like that for a decent payout.
I guess not exactly. But still looks pretty crowded at the top end: https://www.prepscholar.com/sat/s/colleges/Harvard-SAT-score...

It could trivially enable millions or billions to 1 compression, though. It just needs the option of a longer length field. With even a single megabyte of repeated data, it has to split it into four thousand chunks. That's not exceptional in my book.

I'll call it exceptional when it can encode any real-drive-size repeated-character file into the size of a tweet.

I used to feel that way, but eventually figured out a set of design principles that took care of the parts of the game that were stressing me out. Turning off biters, building with a main bus, making a mall for yourself, and building with extra space so you can hack easily will go a long way to reducing the "ahh I'm gonna have to redesign this whole thing" stress.

The witty answer is: "nuclear works in the dark".

For most renewable energies, you need a baseline power plant that can stand in when the wind isn't blowing or the sun isn't shining. Often that is coal or gas.

Nuclear is cheap and has low emission, so it is a great candidate for such a role.

Distributed solar needs a huge rework of the electrical grid, if you want the panels to be able to give back power. The current power grid is setup to handle large power plants.
I kinda felt that way about Factorio, it reminded me too much of doing CPU metal-layer layout (running roads & rails) combined with microarchitecture design (optimizing pipelines).

But in reality, I think "The Stanley Parable" hit a little too close to home for me.

> Nuclear is not a panacea but railing against the technology because humans goofed up, then refused to pay more attention and do things correctly in the future is an irrational stance.

But we didn't even become more careful with existing reactors. The companies running them kept being textbook capitalists and cut costs wherever possible. Outsource maintenance to questionable Eastern European workers. Inspections reveal unexplainable micro fractures near the reactor core? Just declare it safe and carry on. Workers on-site monitoring the operations are retrained electricians, because well, both things have something to do with electricity right?

I'm not afraid the technology is inherently unsafe. I'm worried because it's run by companies maximizing profit, and regulated (indirectly) by politicians caring about getting re-elected, and maybe about their hometown/electoral district.
I took one of those expensive SAT prep courses and yes, I agree that those don't increase scores very much, the program I took was awful.

However, I totally disagree that rich people can't game the SAT. I used to be a moderator at /r/SAT and /r/ACT on reddit. All of the questions and answers for all of the exams, including subject tests are known and published online. Both SAT and ACT routinely reuse exams from prior years, and anyone who puts in enough time to study the old exams can do well on the exams. And rich people have the luxury of more time to study, because they don't have to work second jobs or cook for their families or clean the house after school and have more services that can save them time.
Technological evolution today is very slow, with products coming after years
of research or at best months:
Singularity is
when this evolution accelerates to "near-instant" level - i.e. products of idea are actualized and developed to
state of art instantly.
This would be my definition: it doesn't require a Sci-Fi AI overlords deciding whats optimal for you, just general technological capability that reduce time of development to 0.
