Usually, what I hear from folks is that you come out of using Mithril with more transferable knowledge than something like React.

One example that comes to mind was when someone realized you could implement an incredibly simple atomic CSS composition framework by basically doing this:

/* some atomic CSS */
.primary-color-700 {color:blue;}
.pad-700 {padding:1em;}

/* a bog standard CSS selector string */
const MyWidget = '.primary-color-700.pad-700';

/* a Mithril element */
m(MyWidget) // <MyWidget /> in JSX

So you can get a fairly aggressive CSS optimization scheme for basically free, and you can iteratively improve the quality of your atomic CSS as you learn more about plain CSS / semantic taxonomy practices. And meanwhile, you're still just writing bog standard CSS and Mithril templates. There's no compile-time shenanigans to dedupe styles, no extra library runtime, and CSS is actually CSS so if you server-render you stay on the browser's streaming rendering happy path instead of waiting blocked on scripts.

Now compare with what one would do with most frameworks: one would pick some CSS-in-JS library, get things done and over with, but probably learn nothing interesting in the process and have little idea of what sort of code is actually getting shipped to customers.

They have the power to censor posts on their platforms, and use it, just like the Chinese government has the power to censor the internet in China, and use it.

Portland cement is at least 80% CaO, so in theory it's 63% of the cement's dry mass (CaO + CO2 -> CaCO3)[1]. In practice it's ~43% that value, or 27% of the cement's dry mass.[2]

The problem with trying to replace meat. Is the unknowns about why we survived as carnivores for thousands upon thousands of years and our current obsession to suddenly play god with a food supply.

We don’t know what we don’t know. And impossible doesn’t know why there would be side effects. Or they do and you’ll not know.

Buy grass fed organic meat and eat less of it. We already eat too much.

But how can you say that’s ideal for all? And that’s even suggesting that the mechanisms underlying keep that going for real and not just in name.

America is losing is democracy as the money in politics is determining policy more than the constituents voting [1]. China, meanwhile, is vastly expanding its empire and economy under totalitarian control that’s lifting millions out of poverty [2]. Other countries have populations that want clerics or other religious folks at top (e.g. Iran), or tend to have a history of authoritarian rule and a population that respects that. There are many different forms, and I find it to be cultural imperialism to suggest there is an ultimate form of government for all people. That is coming from your own values, which is due to where you were raised and the larger social norms.... not some commandments from the heavens that dictate what it must be.

Democracy can be great (in theory), but it’s not the only way.

You might want to get outside of your bubble a little instead of making accusations like that.

Perhaps you could explain the case of Elizabeth Heng, a candidate in CA of the US Congress?
If a newspaper published an ad for real estate for “Whites only”. They would be held responsible.
Better free tier to make sure it goes viral. Even more important as it's appeal is limited to devs and marketing types. Charge corporate clients for volume and service. This could have been the Google of source code but you need to take the risks Google took in making their search engine free to the masses otherwise it remains a niche product.

So if I get a radio license and then broadcast an illegal ad, it's the FCC's fault.

Why is everyone trying so hard to turn facebook (and google, twitter, etc...) into a filter on everything we say?

When facebook gets held responsible for all content in all jurisdiction it will err on the side of proscription. It was only about 10 years ago that many now acceptable (mandatory even) progressive positions were not in favor.

It won't be another day or two before there is another article bemoaning google acquiescing to China. Pick one. I'll take the one that is open, the crazies broadcast their fake news and we have the occasional illegal ad.

By the way, if these ads are illegal and conducted through facebook, how easy is it for the FHA to look up who is responsible and go after them. Their whole job is done for them. Going after Facebook is sensational and feels good I guess.

> Someone needs to watch the stacking process.

Why do you say that? We have fully automated CNC machines and 3D printers that can make things to amazing tolerances without human intervention. Stacking blocks neatly isn't a hard AI problem like self-driving cars are.

> If there is a single error the whole tower can collaps and do a lot of damage.

My reading of it is that the whole thing is fenced off anyway, since it contains an autonomous crane. Just put it somewhere that land isn't too valuable. If it all does collapse, the worst that can happen is it damages itself. Most wind turbines are similarly situated in places where, if they fail, there's nothing else really there to damage anyway.

> Is the low-cost-concrete a strong enough building material?

Presumably so, or if it's not, then it won't be used. I'd leave that to the engineers.

> The generator needs cooling (in hydro pump it is cooled by the water flowing through)

Cooling is not a hard problem. There are much larger plants generating way more power that operate 24/7 that handle cooling just fine. This idea is only generating as much power as a tower crane typically uses anyway, so whatever a tower crane has for cooling its motors should be fine. Probably some kind of closed loop liquid cooling system going to a big radiator with fans, like for a typical automobile engine.

There still needs to be the equivalent of a series of O-rings between the piston and the cylinder bore to prevent the piston from sinking. I'd guess that it is the second-hardest technical problem, after the considerable challenge of isolating the piston.
> I think social media sites are removing people at .1% outlier belief system that most people deem disgusting enough to warrant taking action to not have associated with their brand.

I don't think that's true. Tommy Robinson's beliefs about Muslims are held by a good deal more than 0.1% of the UK population, yet he was banned from Twitter.
The difference is that tower cranes capable of carrying 35 tonne blocks can be bought off the shelf.

As for lifting an entire landfill, how the hell would you accomplish that? No such machine exists, and the support columns required to do so would be utterly massive.

Also, I don't think a strong enough material exists to make that sheet out of.
Not at even remotely the same cost, no.
Survivorship bias. Agrarian societies that were based on male dominance, hierarchical social strata, and conquest of competitors were the ones that developed into the early empires that today's societies are descended from. There are and have been matriarchal societies and also more egalitarian and less confrontational ones, but they did not expand at the same rates or compete as well with those that ultimately won out on geographic and resource control.

This does not mean male dominance and social hierarchy are preferable. It just explains why they are the norm. There are many good reasons to reject them as the norm now that we can.
To be honest, it would have been better to explain how they do the spectroscopy than to just say "you don't understand" and downvote. I should have raised a question instead of making a statement, the response should have been an explanation, instead of basically "you're an idiot" (which still no one has done as of this time). They are making the same error I did. The article posted didn't explain, the paper costs $9 to read. I wouldn't call this a productive discussion at this point.

Edit: someone just attempted to explain the technology behind it, thanks amluto
And none of that represents a legal sanction for copyright trolling. Nobody hates them for their identity theft, shell companies, and lies to the court. Everyone hates them for copyright trolling! And copyright trolling is the only thing they did that the court says is fine! But all the coverage headlines how the court is smacking down "copyright trolls". No it isn't. What is the cause to celebrate?
Late stage pre-IPO stock is usually fairly valued, and very few companies at this stage would consider ISOs (which have somewhat of a tax benefit).

Therefore no hard rule, just run the numbers on an offer-by-offer basis. Depending on your fit and skill set some employer might kick in some premium to tilt the scale in their favor.
Sounds less efficient than just using a high efficiency electric motor to power a crane as in this proposal.
That doesn't decrease the openness of the internet, just the "openness" of Facebook, doesn't it?

I happen to think whether they should be allowed to do this considering their size is worthy of a public discussion, but it doesn't affect the overall internet, at least how I think of it.

The only part of that page that discusses diet talks about how okinawa owes it's longevity to "A diet that is heavy on grains, fish, and vegetables and light on meat, eggs, and dairy products.'

If you look at the Wikipedia article for blue zones(areas with especially high levels of centenarians). https://en.m.wikipedia.org/wiki/Blue_Zone

They mention that one of the things that unites these areas is a mostly plant based diet.
I have always loved fountain pens. But I am currently using a mechanical pencil(Staedtler 925-25-05) only. I guess fountain pens are not suitable for note taking and drafting and maintenance makes using them a luxury for me. Mechanical pencils provide fewer options but still a great joy of writing experience(but nowhere near a proper gold nib pen).
You're accusing me of engaging in diatribe? Audacious!

Google has 88,000 employees. I don't know what their definition is for "All Hands", but it's probably a lot of people. I think there's a saying about this. 88,000 people can keep a secret if 87,999 are dead?

I know you're hardly the first, but I laughed when you called them "Googlers" instead of Google Employees. I can't wait until Google calls up its levy of Googlers to arms and they hit the campaign with retinues holding bright blue-red-orange-blue-green-red standards. I believe the feeling of betrayal is real but it's still funny.

I assert this is more about loyalty to your liege/realm/company than a practical thing to be upset about. The people doing the cursing on a hot mic seem to have built their identity around the company they work for. I get how that could happen but it's still peculiar to me, I firmly believe that no matter how many times they say it, the company you work for is NOT your family, unless it's a family owned business and they are.

It just occurred to me that you might think I'm being anti-corporate because of the comparisons to feudalism. Maybe you felt an instinctually negative reaction when you read the word. I'm much more dispassionate myself. Taking the emotion out of the words allow you to see that the systems have enormous similarity with merely different vocabulary, like angular vs. react, except feudalism isn't as dystopian as angular (Ha Ha, google joke). Peasant::Non Managerial Employees, Youtube:Google:Alphabet::Duchy:Kingdom:Empire. It's there, you just have to look!
Millions of people live in abject poverty too, so what? It’s on par with an entry level fast food job, but a lot more risky given the inherent dangers of spending a lot of time on the road, and with no possibility of advancement. Given that entry level burger flipping is considered the bottom of the barrel, I wouldn’t be too impressed. I think it’s worth fighting for jobs that have a future, the possibility of a living wage, benefits like healthcare, and at least the possibility of advancement don’t you?
Some people are way better at finding issues than others, even in other's code bases.

Another good skill to have though, that is unfortunately not super duper common either, is being able to figure out and match conventions and patterns in code bases when introducing changes.
The idea involves lifting thousands or tens of thousands of blocks, not just one. Of course it's ridiculous to have an entire tower crane dedicated to lifting a single block, but that's not what they're proposing. The linked article has a rendering showing how many blocks are involved.
There are no good guys.
> History shows this kind of thing is just incredibly dangerous. If everybody likes culture that's enjoyable and easy, easy, self-satisfied thinking predominates. Then suddenly everybody is marching waving big flags and wearing funny hats, because it's a lot of fun, and makes you feel great to be part of something.

Please provide a reference for this. It sounds too much like a just-so story for me to take that at face value.
If they don't call themselves Sisyphus Energy they're missing out on a great poetic opportunity.

> In Greek mythology Sisyphus was the king of Ephyra (now known as Corinth). He was punished for his self-aggrandizing craftiness and deceitfulness by being forced to roll an immense boulder up a hill only for it to roll down when it nears the top, repeating this action for eternity.

Its quite an ingenious idea. Could even hollow out a mountain to do this, avoiding the co2 cost of concrete.
Looks amazing and fast, congratulations. If you don't mind sharing, What is your tech stack ? How many developer hour were consumed developing it and how many to maintain it ?
There are no good guys.

And yet, there are bad guys. Churchill was a bastard, and no kind of “good guy” yet Hitler and the Nazis were the bad guys. C‘est la vie. Stalin was one of the bad guys, and so was Slobodan Milosovic, and so is Dick Cheney, Tony Blair, Pol Pot, etc. Good guy is a tough category to fill, but history is full of inexcusable monsters and we should be careful with our moral relativism.
Jeff Bezos doesn't like the idea of 'work-life balance'
This explains why Japanese train conductors make a big deal out of delays of a few seconds. It’s very common to hear announcements like “sorry we were delayed by 20 seconds because someone was holding the door.” Because that delays the entire line and all connecting trains by 20 seconds. And I’m sure these delays are tracked to measure performance of the conductors.
I wouldn’t worry too much. Just take a look at Chinese tech companies trying to enter new markets and how they’re not doing too well. Alibaba has the right idea. They just invest.
> the difference is excluding (discriminating) versus targeting. Targeting is legal, discriminating is not.

Can you articulate a difference between "targeting" and "discriminating", other than one being legal and one being illegal?
It’s Not Technology That’s Disrupting Our Jobs
I think Buddhists would disagree that humanity has survived solely as carnivores for thousands of years. Plenty of other cultures have existed on solely vegetarian/vegan diets as well, throughout history. Peasants within meat-eating cultures also did not always have frequent access to meat, and thus ate primarily vegetarian, or perhaps pescatarian. The idea that humans have always eaten meat and that it’s an essential part of the human diet is a myth.

Someone would need to run the costs per GWh stored and generated. To me it looks like once you built your rail loop you could run a lot of cars on it. Still, building instead quite a lot of cranes might be cheaper.
You're orders of magnitude off on the scale involved.

A single one of these concrete blocks is 35 tonnes. To get useful stored energy levels you need thousands of blocks. So you're looking at something like 100 kilotonnes of total mass. That's way, way, way more than any movable bridge weighs. Bagger 288, the largest mobile machine ever built, only weighs 13.5 kilotonnes, and all of that weight is supported by the ground on massive treads. To be able to lift many times the weight of Bagger 288 over 100 m in the air defies imagination as to what would be required. It would require billions of dollars to achieve, most likely.

Contrast with an off-the-shelf tower crane that costs a few million.
It's displaced several competitive ecosystems.

Many of the things Facebook is used for were originally disparate services-- think of the smaller social groups that would have been mailing lists, or at least message boards. Event management-- RSVPing and messaging participants-- used to be a fairly competitive space too.

If you need services in those spaces, and lack the technical skills to roll everything from scratch-- but it doesn't fit with the Facebook model or business tastes-- you've got far fewer options than you had 10 years ago.

I'm thinking, for example, a community I enjoyed many years ago. It was for collaborative writing so most everyone posted under pen names. In 1998 it was implemented by a mailing list which got cross-posted to a newsgroup. In 2005 it would have probably been thrown up on a cheap "hosted forum" service like ProBoards. In 2018 it would be a Facebook group, and almost certainly stuck with posting under real names. And that's the most benign "we lost something" outcome I can picture.
this is a consequence of facebook owning the network (on purpose obviously), as opposed to something like the web or the air which is not centrally owned. yay capitalism!
I can imagine living next to one of these facilities and thinking "What the hell are they trying to build?"

I think they're saying that the tool may have been used like this:

1) Create an ad targeting straight couples, and hide it from gay couples.
2) Create an ad targeting gay couples, and hide it from straight couples.

If you query for "is anyone running an ad hidden from gay couples", this would return "yes".

However, my hunch (hope?) is that the prosecution was clever enough to account for this, and are specifically finding ad campaigns which are "unbalanced" (eg; there is no ad targeting group X).
It is almost as if we have geographic areas larger than zip codes such as cities, states, regions, that can be targeted without running afoul of laws about targeted advertising of real estate.
How does one conclude that a kernel panic means the T2 is insecure? The kernel trusts the T2, not the other way around.

I agree.
> Even C has a bunch of functions to work with the date struct as an opaque type....

Yes, for conversion to/from time_t, formatting, and parsing. That's my point; you use the integral type whenever you don't care whether it was a Thursday because the integral type isn't going to waste your time.

> And then you use a better class. In Java you use something like JodaTime in .Net you use NodaTime - a .Net library written and maintained by Jon Skeet (the person with the highest ranking on Stack OverFlow). If that’s not good enough you write a custom extension or mixin to handle your special snowflake handling and still let all of the consumers treat it as an opaque type.

Stop with the hero worship. You should do things that make sense in context. Recommending that everyone use a library in all contexts because it's written by Jon Skeet is a ridiculous thing to do. (BTW, it seems like the Joda-Time people recommend you use the standard java.time package instead.)

> We were talking about an accountId that just happens to be represented as an int. You’re not going to be doing math on an account id. Also neither .Net with generics or even C++ templates have the boxing and unboxing issue.

Who are you to say I won't do math on account ids?

> If there was a business case to change the underlying structure - by definition there was a “good reason”.

In the situations the two of us have discussed, there is no business case to create these interfaces in the first place. Where is the good reason?

> Even so, you should still not send your internal representation that may change across the wire and do some type of mapping. Are you going to send the same model that came from your ORM that’s tied directly to your database across as the representation to the outside world?

What ORM? What database? If I'm using an ORM and a database, high-performance time operations are likely out of the question.

That is exactly like a Dollar General. Small food section in cans and boxes.
Rolling stock isn't cheap either, though. Not even remotely close to how cheap a concrete block is. Rolling stock typically costs in the millions per car. The rail might not even be the most expensive part.

The nice thing about the crane idea is you don't even need a lot of cranes, you just need a lot of stackable mass. The rail idea needs a lot of movable mass on wheels, and a lot of siding to store it on. It seems like the rail idea would need more land as well, plus it only works on hillsides.
