The BEAM is awesome, but both Elixir and Erlang are not really great for concurrency. They lack support for pure functional programming, which is really one of the most useful things in this area.
> Actually, being extraordinary is something most people can do.

I think that this isn't so different from the article's point, just phrased differently. But I also think it's worthwhile to remember that, while you can be extraordinary, you don't have to be. Giving someone permission just to enjoy something, without having to worry about whether they are extraordinary at it, is as important as reassuring them that they can be extraordinary.
Looks like the regulators failed. Where are the clean diesels now? Gone because the NOx limits created by the aforementioned regulators set the bar too high.

Instead we’re now only making ICEs that are gasoline-powered for passenger vehicles. Burning 1.5-2x the carbon for the same distance as clean diesel. IMO VW and the others who have since quietly withdrawn their clean diesels from the market hoped regulators would pull their heads out of their asses and get real on NOx limits. Cars like the TDI line were about 1/16th the NOx emission of a standard diesel-powered box truck.

Yeah, we had to intervene with respect to a particularly scummy financial planner from the church in particular. Completely idiotic fixed income products that made no sense relative to the alternatives. He was a non-fiduciary and taking commission plus absurd fees, of course.

> 2. The productivity gains of something like Bazel and Pants are pretty amazing if you are working within a monorepo.

In theory, maybe. But can anyone external honestly look at what Twitter has shipped for the last few years and justify that it was at all likely their productivity problems in engineering had anything to do with the build system.

I've worked as an FTE in a platform team for a major public tech company before, and I don't know many smart ones that came out of that thinking it was a good trade off to have teams whose very survival necessitated potentially unnecessary platform tooling / changes -- unless you're literally Google or FB and can see measurable results from optimizing that tooling.

Twitter never got close to that point.

Conversely, by choosing the axes differently, Olympic gold medal winners become ordinary people.

Also, being extraordinary in one thing (e.g. running) doesn't mean what people think it means because how many people actually try to become a professional runner? If everybody tried, Usain Bolt would be ranked #1000 or perhaps even lower.
There's also a tremendous difference between:

1. "Extension sees data on pages for which it's activated, and might modify that all kept locally", and

2. "Extension sends all page information to The Cloud^W^W Somebody Else's Computer where it is probably being shared with umpteen third parties, advertising^W behavioural manipulation and surveillance organisations, and will be preserved in crystal until the Heat Death Of The Universe.

Why desktop, and most especially mobile platforms / operating systems fail to either distinguish or permit control between these two scenarios is ... utterly beyond me.

There is Steve Krenzel's recent account of being pressured, by both a Twitter marketing exec and the phone company requesting the feature, to track "when users leave their house, their commute to work, and everywhere they go throughout the day".

> there is still some acceleration that occurs as the engine drops from 6-7k RPM down to idle.

Not in any vehicle I've operated. The moment I pull off the throttle completely, it stops flowing any more than idle speed fuel mixture into the motor. Without that combustion power, it starts to act more like an air compressor almost immediately, causing negative force output. It is taking energy from the crank to try and compress a mixture which, when combusted (if even combustable, most likely not), results in less expansive force than the force it took to compress. This is even more pronounced at high RPMs as that action happens more times every second.

If I let go of the throttle on my motorcycle at 9krpms and like 70mph or whatever it feels like I pressed hard on my rear brake instantly, for all intents and purposes. You'll feel your weight get thrown forwards immediately.

If your car continues to accelerate after you've taken your foot off the gas something is wrong with your car.

Last.fm probably changed hands a few times, yet, to me it is an example of how you don't need to keep shoving features into a product/service to be happy with it.

I would agree that MMOs in general are a time sink, but I am not sure I can absolutely equate that with a waste. There are some things I learned playing some MMOs including real microcosm of market psychology, interesting uses for linear regression and even some basic scripting. One of my best friends is effectively a result of a chance meet in an MMO. And that is before the argument that time enjoyed is hard(er) to label as a waste.

For the record, I agree with you in general, but I do not want to overgeneralize and add some nuance, because I do not want people to automatically say game time = useless. Tons of leisure activities do not yield immediate dividends ( reading books come to mind ), but are not without benefits.

Minor disclaimer: I am typing all this as an MMO recovering addict ( it got to the point where it was interfering with my work life ) so some take my opinion with a grain of salt.

One thing that lately really fascinates me is the Younger Dryas impact theory. The discovery journey was Joe Rogan (Podcast) -> Netflix Docu -> Joe Rogan (Youtube) -> Other Youtuber. Which in itself is a content consumption cycle that I had before.

What I find fascinating about this is that there are new discoveries of underground structures that really changed the game.

It solves the mystery why ancient megasites are looking at summer and winter solstice, because that's where the danger would come from.

It ties in with flooding myths that are found in many cultures.

I think the real and maybe not directly stated point is that every person on a planet with billions of people is virtually guaranteed not to be the best at something. It is statistically unlikely especially given how we do everything we can to label people into groups and funnel them accordingly to be used ( and be useful to ) by society.

That does not mean that a given person should not try to get better, because this is the only way you will start getting to a level of competency and maybe, with some additional luck and push, to a top performer level. Not everyone can be number one, but extraordinary ( the attached article ) definition allows for that. And being second best at 'whatever' sure beats just complaining about everything you did not get a chance to accomplish.

<< Is that not sufficient?

I honestly don't know. It is a very personal question each of us should answer internally. I, personally, want to do better and you do want to keep giving yourself progressively harder goals. I am currently working on a plan for 23-25 and I am getting kinda excited, because I believe it will move me to a better place in terms of my career ( and by extension better family life ) and interests, but I know it will require some buckling down and really polishing some skills. Maybe it is spending too much time on HN watching other people's 'Show HN' threads that got me to question myself "Why can't I do this?/"What is missing?"

I already know I can't be best. As mentioned in the very fist paragraph I do not believe it is even possible, but I still think there is a lot of untapped potential. Wasting it would be a shame.
Same here. Looking at a list of companies who have paused advertising on Twitter; I have zero interest in many of them. Like the California Lottery or DirecTV.

While I dislike advertising in general, if I have to see ads I hope it's an opportunity for smaller businesses to promote actually useful products for me.

Controversially I think the problem with taking this point of view is that it's also an argument for why seniors shouldn't be allowed to vote.

However, I think old people should be allowed to vote.

So really what we should be looking at is something more nuanced - that perhaps excessive screen time is wasteful, maybe even exploitative, even for seniors.

There is certainly an unevenness to the moral panic of children with screen time - but moderation is key, not blanket statements.
The cruelty does seem to be the point.

The thing about microgrids is that maintenance falls onto the owner.
You still require specialized knowledge and perhaps team of people who can handle it to maintain the microgrid and repair it.

You still require supply chains for the complicated parts that cannot be easily replaced, mostly batteries and inverters. In a shortage situation, central grids will be under pressure to be fixed immediately, but your single set of wind turbines or solar panels might not be.

So the way I see it, microgrids would be maintained by cities and communities instead. The level of distribution would make it similar in action to the times of old coal power plants, one per city.

It’s got to the point where if I find myself in cordial debate with so,embody whose thesis I disagree with (in 280 character chunks at the time) I thank them for the debate.

And that’s the thing: if you go into a conversation only to ‘right’ the other person’s views and are unwilling to revise/question yours then you’re not debating, you’re preaching… and there’s way too much of that already. Furthermore some of people are very ‘polite’ (in that they let you expound your views) but I’ve noticed many just wait for an option to lunch into their monologue. That isn’t debate either. It’s socially less jarring but in a way intellectually dishonest.

Limiting global warming now can preserve valuable freshwater resource
A research team has found that the Andean region of Chile could face noticeable snow loss and roughly 10% less mountain water runoff with a global warming of approximately 2.5 degrees Celsius compared to pre-industrial levels over the next three decades. The study also shows that what happens in the Andes could be a harbinger of what is to come for the California Sierra Nevada mountain range, and highlights the importance of carbon-mitigation strategies to prevent this from occurring.

> So we don't have those fixed costs - they are already paid.

No, that's generally not how infrastructure is funded. Infrastructure is funded by bonds that are sold and have to be serviced. So the payment for the fixed costs is spread out over time -- ideally over the lifetime of the asset -- and what happens when you add unreliable source that are cheaper -- like solar -- is that they cannibalize the revenue stream used to service the debt and those plants are taken offline right now, or they have to be subsidized somehow by the taxpayer -- which is why regions that make a big push to solar end up paying high energy prices and need to import a lot of energy. They are not paying high energy prices because solar is expensive, but they end up paying high prices to keep their reliable plants online. Or they require subsidies from the taxpayer. California is one example, but you see this often in Europe as well. California just got a billion dollar Federal subsidy to keep diablo online for a few more years, but the reason it was going to go offline was because it needed massive subsidies to remain operational in a market in which it competes with solar. But at the same time, solar can't replace Diablo without blackouts and water shortages - Diablo supplies 10% of California's energy and is used to pump water, so this is something that requires reliability, but it is losing money every year because it's cannibalized by solar. That's the situation of the household that chooses to buy both cars -- that household has to spend a lot more.

Solar has basically made nuclear uneconomical in the U.S. because nuclear has massive fixed costs but almost no variable costs, so it can't exist in a de-regulated market with solar -- the solar just drives it out of business. At the same time, solar is driving greater use of coal because coal plants have the cheapest fixed costs. So Germany was ditching nuclear and using more coal as a result of deploying all the renewables. If you don't pay extra to maintain your reliable capacity, you get blackouts or pay emergency rates to beg for energy from your neighbors (California has to import 20% of its electricity).

Rational actors -- like the household choosing between the two cars who knows they need to drive every day -- are required to plan for sufficient capacity look at this and say "we're not ready to deploy solar at scale" because they want to avoid the blackouts and price spikes. Politicized actors choose a different route, and you get the energy mess that is California, UK, Germany, etc. And all of that is solely because of storage, and it gets worse the more solar you deploy without storage.

It's because LISP has a "great filter" for high IQs.

Programming has many such filters:

Understanding pointers / references separates the python/script kiddies from the "real" C programmers and understanding von neumann architecture.

Recursion separates the programming-is-a-job with the beginnings of algorithmic understanding of computation.

LISP is heavy recursion, non-infix notation, lambda calculus, and other concepts that are simply too much for a garden variety programmer.

I suspect that $4m a day number Musk has been tossing around is rooted in his terrible financial investment. He purchased the company for $44b, which has something like $1.4b in interest every year? Which would be $3.8m a day.

To start with who will be the arbiter of value?

While I would agree that advertising can result in distorted priorities it isn't inherently evil. We used to have an internet with both ads and rational incentives. Even then the value of the internet service could not cover itself without advertising.

The main point though was that the cost of the internet is a mix of direct and indirect cost. I seriously doubt there will be enough people willing into incur the direct cost for modern services at a level that will co er those indirect cost incurred by the network and content providers.

While an ad free internet sounds great it isn't very practical or necessary. The answer is on the user end rather than the provider end though. Stop rewarding the perverse incentives instead of pretending we can wish them away.
