A city will not stay a pure "investment vehicle" forever - the RE-values bubble has to deflate at some point. But it can take some time because the market is so illiquid, and a downwards correction is especially likely to be erratic. Then the gentrification/speculation process starts all over again and we're back to square one. Want to improve things? Tax away urban rents by raising property taxes (the opposite approach to California Prop 13) and the relevant market will become far more liquid, and less prone to excessive real estate costs.

> this is one of those policies which is both environmentally friendly and makes piles of economic sense

To a broader point, this is how real change is enacted: make it matter to enough folks, usually by means of economic pressures. I.e., make bad things cost more than good things. Although obviously ham-fisted tariffs, etc. aren't very effective for a host of reasons. You gotta be more subtle than that.

It's almost as if capital is too concentrated, to the point that the people with who control it don't know what to do with it. Oh wait.

The basis of capitalism is markets, and the wisdom of the crowd (the "invisible hand") controlling them and making them efficient. VC's (and wealth concentration in general) are the opposite of that. They are the very-much-visible hand.

We'd solve this problem with progressive taxation and a basic income (a healthy side-helping of better funding for public services wouldn't go amiss either).

IMO, if you believe in free markets, then your position is inconsistent if you also believe if you also believe in unconstrained wealth collection. Because once that wealth is concentrated, the market is automatically distorted.

> So, why are we teaching it?

Here's a list of random, unresearched reasons:

1. It teaches fine motor skills

2. Some people learn reading and writing better when writing by hand. Some people learn better in lectures when taking notes by hand.

3. Tech isn't always available. Sometimes pen/pencil and paper are all you have when you really need to write something.

4. Drawing, painting and other art require learning how to hold and use pencils, brushes, pens, and other tools in a fine, controlled manner. If people are going to learn to make art with manual instruments, they may as well learn to write at the same time.

5. Text input is genuinely more awkward on keyboards for many non-Latin languages, and is less emphasized in development of software products. That relegates those language learners to second-class status as they grapple with tools built for the Latin/Cyrillic world.

6. There's a ton of cultural significance to writing by hand: calligraphy, religious or legal rites.

I can probably come up with a dozen more but to get to your next point.

> And the time schools save can be used for any number of other things.

If you want to talk about outdated holdovers in children's education, summer vacation is the biggest one, dating from when kids were needed on farms to help bring in the harvest. Schools could simply eliminate summer vacations if they really wanted more time to educate. No more complaints about teachers only working 9 months/year, no more summer learning slump (or whatever it's called), no more paying for daycare or summer camp 3 months/year. A lack of time is not a real problem.
The article doesn't really touch on how this plays with generics, if at all. Anyone know if we can do:

public record MktOrder(T currency, int amount)<T> { }

or

public record MktOrder<T>(T currency, int amount) { }

Would be a bummer if it breaks the idiomatic (and canonical) way of working with generics. In any case, it's a much needed and welcome feature.
That’s “AI” alright.
I wonder what the breakdown is on overall effectiveness, sometimes you can get some very perverse results.

I do see a lot of shear curtains, the sort of light gauzy material that's easier to see out of than inward. Heavy, opaque curtains tend to draw a bit of gentle curiosity, as though the occupants might have a reason to hide their stuff. It's not a big deal either way, but living in a house without a clear front window would be terribly depressing for me.

I bet it'll be easier for your wife to accept once you get to know your neighbors. Most Dutch neighborhoods are intensely pedestrian, and waving through front windows buys you consistent contact with your neighbors for little effort.
I think especially in politics a lot of people don’t really want to know what’s true but latch onto whatever “fact” that feels good to them. When the whole birther issue came up I had several discussions with my right wing neighbor who even after all evidence pointing towards this being nonsense still thought that Obama was born in Kenya. When you look at the stock market or unemployment there was continuous improvement since 2008 but plenty of people hold the idea that the country was in bad shape either before or after trump’s election. No fact or chart can convince them otherwise.

That’s why a lot of people fall for fake news because they don’t really want to know the real (and often very complicated) facts.

Why should interstellar travel be realizable? If FTL is not possible--and there is no reason to think it is--then interstellar travel requires a craft that is capable of maintaining a colony-sized group of people for centuries or millennia, industrial bootstrap capabilities, repairs for everything in the meanwhile, food and energy for the trip, and the fuel reserves to slow it down at the end and land. The size that such a craft needs to be plausible suggests that the fuel amount in question will probably be best measured in something like "years of total Earth natural gas production."

Can be used in lambdas, all libraries are modified and aware of it etc. C# Nullable<T> is near useless because it only works on value types. I.e., you know, the types that are least likely to generate NullReferenceException for you.
So, at first we encouraged military companies mergers to save our money (back from 1980s?) and left only with a few monopolies, then suddenly there is only one company that can make our military chips? What a surprise! And now we have to pay premium to have them made on our soil? Same situation with non-military monopolies and near-monopolies.

Though if they really dug that much tunnel under a city in such a short time, maybe there's an actual innovation in a better way to make subway tunnels?

Don't believe the hype that this is "under a city." It's under a bunch of parking lots, which have little to zero underground utilities or other infrastructure.

It's not like they're burrowing under New York. But it might be good practice.
But it's not actually AI, it's just programmable probability.
> ELI5... why is digging a tunnel tech news? Does Elon dig them faster or more cheaply or something?

Honestly as a 5 year old you are not going to get it.

This is multi levelled. Some people just like Elon. But what's really however interesting is how Elon is changing manufacturing. It's like a new Kanban

But it's not 5 year old stuff. I'd just say,

I know all the other kids like rockets and think they are cool to watch take off, but tunnels are pretty cool to watch too.... and so are processes but that's adult stuff for now kido (and give them a wink)

How would you compare records to c# language features then? Are records value or ref types? Do they live in the stack or the heap?
Google as ChromeOS/Android owner can do whatever they feel like it, regardless of the driver model.

In fact, Android since project Treble has a driver model similar to Windows.

Linux drivers are considered legacy on Android.

Likewise they could have contracts in place that would force their suppliers to provide updates for X years.

You are conflating SAP the company with SAP the ERP with SAP the NetWeaver/ABAP platform.

From my experience the actual platform, while certainly showing its age, is surprisingly well designed and still very much relevant, despite SAP the company doing its best to replace it with something “modern”/“nosql”/“bigdata”/buzzword-of-the-day. I think that it would do good to many web-oriented developers to study how SAP/ABAP works, because it follows the web-style request/response + background tasks architecture since it’s inception. One interesting thing is that the low-level network protocol used by NetWeaver is ugly undocumented binary thing that you are supposed to use through binary blob, but API of said binary blob has very much the “POST random JSON somewhere and get JSON back” feeling.

For the ERP itself there are many people downthread saying exactly same thing: the ERP works and is well thought-out. And almost always breaks horribly when you start to customize it to match your random ad-hoc business processes.
According to Valuewalk, they had $6.5M AUM as of July 2019.[0] Their size is primarily a function of the passive indexing they offer, do you consider that AUA? Or AUM? I'd argue that it's AUM. The reason their revenue is so low (by bps) is that indexing is extremely low-fee.

It's interesting to look at a history of the biggest firms.

- America's Top 50 Companies 1917-2017 [1]

- A Century of America's Top 10 Companies, in One Chart [2]

- Top 15 Largest U.S. Companies by Revenue (1954-2018) [3] (video 5')

(Note: the USA is best documented and as the world's #1 GDP for a century it's a good sample of leading trends).

What we see is a clear shift from primary products to intragrators — makers of final products. It's unclear to me whether "tech" should be seen as either, because software can be very low-level or very high-level, it's pervasive vertically to the whole pre-existing technology stack of civilization. Hence why, perhaps, it's so mesmerizing to us now.

Among the 4 companies cited here, Google is strangely the one that I'm the less confident about in terms of very-long-term prospects. Apple has clearly become a luxury brand, and these last centuries; Microsoft is as strong as it's ever been with all things enterprise; Amazon is, well, Amazon.

Google however, it's an engineer ethos at first (my first tech love), but it seems like corporate drove that away enough to resemble other companies (looking at Facebook, Tesla..). But said corporate management seems aimless, opportunistic more than vision-driven, more about the what/how and not a clear why. The moon projects counter-illustrate that fact but how many of those will actually become Google's main drive to rock the 2030s, 2040s, and beyond?

And yet, as far as the heart goes, Google is the one I'd love to become something more, it's the one I wish I had founded bar none but Musk's. I just don't see it top 10 past 2030, if even that.

The article actually hints that there are too many VCs (with lots of money, sure) and not enough good deals.

OP is talking about affecting astronomy the science, not astrophotography the hobby. Land-based survey telescopes are incredibly useful cheap tools that do not have alternatives.
Configurable I like, customizable I don't.

My experience is that customisation gets turned off eventually, it always breaks something. Either that or it just doesn't get used. Companies are much more similar than they would like to admit. If an ERP is not going to work for you 95% out-of-the-box you should probably find something with a better fit.
But case classes are also algebraic data types so Java is not yet as great.
"A spacefaring species could easily settle the entire Milky Way given billions of years"

That's somewhat of a wild assumption. What's a "spacefaring species"? Are we one since we've built a few ships and went to the moon?

Have they solved problems that might be intractable, like being able to travel anywhere remotely far in anything else than a "generation ship"?

Have they found the power to deploy those ships, and the materials (and amounts required of them) to withstand the radiation of space, incoming meteors and space debris over decades of flying, while still being able to propel their spaceships out of their gravity?

And why would those settlements even be able to survive in space, going out on some remote systems, and not knowing what they'll find there, and what exactly their Earth-like planets will provide them?

>William Newman and Carl Sagan later wrote a major rebuttal to Hart’s work, in which they argued that the timescales to populate the entire galaxy could be quite long. In particular, they noted that the colonization fronts Hart described through the Milky Way might move much more slowly than the speed of the colonization ships if their population growth rates were so low that they only needed to spread to nearby stars very rarely. They also argued that being a long-lived civilization is inconsistent with being a rapidly-expanding one, so any species bent on settling the galaxy would not last long enough to succeed. In other words, they reasoned that the galaxy could be filled with both short-lived rapidly expanding civilizations that don’t get very far and long-lived slowly expanding civilizations that haven’t gotten very far—either way, it’s not surprising that we have not been visited.

That sounds much more logical!
Respiratory problems are greatly decreased by further adoption of electric transportation, especially in chinese megacities where the situation was dire.

Autonomous bus and taxi services led to less casualties on the streets because less people are still driving themselves (less DUI, being distracted, tired or otherwise not fit to drive).

Taxi services got a lot cheaper because there are no longer drivers who need to be paid which in turn accelerated the transition away from car ownership.

Traffic flow also improved because having a small fraction of autonomous vehicles on the road already prevents traffic jams out of nowhere by cushioning the density waves that can appear in traffic by human drivers (that's really a thing!).

Overall look of cities improved since less parking spots are required. Rules that regulated required parking spaces for customers were lifted which gave the opportunity to open more shops in closer proximity.

I will add it later if I can think of more.
I have sciatic issues--my leg feels either numb, or on fire when it acts up.

I bought an inversion table. I get in it backwards and hang from the affected leg (the other I leave free) for about a 40 count. It brings me from pain to fine in usually a single session. Mind you, I don't have anything herniated and I think scoliosis is pinching the nerve in my case. I am not a doctor, and try this at your own risk. For me it is life changing.

The Shadow of the Past,The Fellowship of the Ring. [Frodo expresses his disgust for Gollum to Gandalf having just learned that Gollum likely informed Sauron that the ring is with Bilbo in the Shire]

[Frodo] “What a pity that Bilbo did not stab that bile creature, when he had the chance!”

[Gandalf] “Pity? It was Pity that stayed his hand. Pity, and Mercy: not to strike without need. And he has been well rewarded, Frodo. Be sure that he took so little hurt from the evil, and escaped in the end, because he began his ownership of the Ring so. With Pity.”

“I am sorry,” said Frodo. “But I am frightened; and I do not feel any pity for Gollum” “

You have not seen him,” Gandalf broke in.

“No, and I don’t want to,” said Frodo. “I can’t understand you. Do you mean to say that you, and the Elves, have let him live on after all those horrible deeds? Now at any rate he is as bad as an Orc, and just an enemy. He deserves death.”

“Deserves it! I daresay he does. Many that live deserve death. And some that die deserve life. Can you give it to them? Then do not be too eager to deal out death in judgement. For even the very wise cannot see all ends. I have not much hope that Gollum can be cured before he dies, but there is a chance of it. And he is bound up with the fate of the Ring. My heart tells me that he has some part to play yet, for good or ill, before the end; and when that comes, the pity of Bilbo may rule the fate of many.“
> For some of them, the www-data's home directory is the DocumentRoot

“Well, there’s your problem.”

Don't expose any ${HOME} to the world! SSH keys are not the only exploitable file in a typical homedir (or even auto-generated from /etc/skel/)! A few files that come to mind:

# other keys
~/.gnupg/

# probably lots of app-specific risks
# (e.g. saved login info)
~/.cache/
~/.config/
~/.local/share/

# if it's also a desktop system running X
~/.Xauthority
~/.mozilla/

Yes, protecting ~/.id* with a passphrase is important and leaking ~/.ssh/known_hosts can have consequences, but this type of exploit shouldn't even be possible. Don't share your homedir - which contains most user-level config files on UNIX systems - with the world. DocumentRoot needs to be contained in a subdir. (edit: or even better, contained somewhere outside of /home where it won't overlap with common file paths)
I tend to think of aging as an overall degradation of the system. For instance, there’s loss of hair cells in the ear that reduces hearing higher frequencies. There’s clouding of the eye lens as the proteins there aggregate. Long lived cells like neurons accumulate oxidation and probably die at some slow rate.

I can’t quite see how drugs which modulate existing biochemical pathways can stop, let alone reverse the processes I’ve named.
