That sounds like a great way to get the formatting messed up.
I'm sympathetic to all of these ideas, and I think we should really be talking more about housing on a national level, but there are a few main issues I see that all of the public funding proposals ignore:

a) Housing is, at the limit, a positional good.

b) Construction costs are crazy, e.g. https://www.bizjournals.com/sanfrancisco/news/2018/04/26/con... and not just in the bay area, I spent a bunch of time looking this up with a focus on NYC and they were in the 400k+ price per unit range there.

c) Construction costs go up as density increases, particularly once you need to install an elevator.

d) NIMBYs/zoning/permitting costs.

As I see it, the insane costs associated with building new housing is why we're only getting "luxury" apartments - you just can't make any money because of the high costs.

So where does that leave us? IMO it means we need better transit, but at least for the NYC subway construction costs are insane, and we need a way to build things more cheaply.

I have my own pet idea in modular housing being promising for bringing down construction costs, but fundamentally it is an operational, not policy problem.

And I don't think anyone really has a solution for NIMBYism besides overriding them at a state level, which has not been very effective so far.
For a rather more technical comparison, 4,600 pages is more than the size of Intel's x86/64 Software Developer's Manual, which is ~3-4k pages.

Technically Waymo has been acting like cowboys longer than anyone. They smartened up and got serious about safety around 2015, but before that they were winging it. It was just a goofy science experiment back then.

The Google self-drivng car project was under the leadership of Sebastien Thrun and Anthony Levandowski, and as hardcore engineering types their thinking was 'We'll save more people than we kill', and it was as simple as that.
You haven't solved the fee problem if you haven't solved the energy problem.
Yeah, the chart gives the impression that land is land, and we just decide how to use it. But there are good reasons land is used the way it is. Farmland in the midwest is really really flat, with thick rich soil. A lot of forest land is pretty steeply sloped, with not so much soil. And so on.
Here's a fun invention for ya.

Yandex does it too with their own tech, just mentioning. I think if it actually were standardized properly without a monopoly it could become a good thing.
How about it not breaking in the first place? When people talk about their Macs with pride, the first thing you'll probably hear is "Apple has the best build quality".

A 2017 13" Macbook Pro should not require 5 service trips in its first year. Warranty or not, we're not talking about some $200 piece of crap that's made in China, we're talking about a premium laptop at a premium price.
> That hotel is still doing cash accounting though. If there isn't much at the front desk, how about the bar? The restaurant?

Many hotels have neither of these.
The Jacksons, who Waymo made available for this story, have largely ditched their own cars and now use self-driving vehicles to go almost everywhere within the 100 square-mile operating area: track practice, grocery shopping, movies, the train station.

All rides are free for volunteers, but the Waymo app recently started to show hypothetical prices.

A Waymo spokesperson says the placeholder price is a way to solicit feedback from volunteers and “does not reflect the various pricing models under consideration.” It’s certainly got the Jackson family wondering how the service they’ve come to rely on will soon fit into their lives.

I am assuming no one promised them free rides for life. How easy it is to become dependent on something "free" and not think about what it might cost in the future when you can no longer live without it.
Psychology is one of the worst offenders. A lot of junk science in that field. Some psych papers read more like advocacy than actual science.

A negative article. I spent 2 years writing a sci-fi about a guy who builds a blackhole powered computer to simulate another universe. It got less than 150 downloads in 18months. I did it because I was doing nothing else with my life. Ultimately it failed to be succesful. But I gained a lot. It really helped me get a lot of crap off my mind. I learned a lot. I also read 400 books and graphic novels over 4 years. It was a rewarding proccess and would recommend it to anyone. So in that respect I disagree with this article. You don't need financial reward or peoples approval to gain from the experience of writing a book. Everyone does have a book in them.
It'd actually be great to see something like this absorbed into browser dev-tools.
Chicken or the egg, eh?
It is a pretty significant diversion of land from a natural state though. Cattle grazing, thought it isn’t an ecological disaster like dam building, is quite different than leaving the land untouched.

Plus, a good portion of the country’s good farmland is diverted to growing feed for those animals.

Think of it like: how many acres have been changed from a natural ecosystem to an artificial one for meat eating.
I guess it's strange to assume that nagging hardware failures will just disappear when the warranty does run out
Hopefully this regulation materializes as a regulation on personal transit, rather than a regulation on autonomous transit.

That's the most sensible way to do things certainly. But the huge public resistance to regulation of this sort may mean th self-driving cars wind-up with no regulation and thus with the vast mess we can imagine. I mean, the average driver is going to get pretty angry with the idea that the coming of self-driving cars means they have to drive less. I mean, they spent their relatively scarce money on their car.

So what happens? The US has shown a willingness to ignore the need for basic regulation even the results are miserable chaos. I can't think of a more likely circumstance to continue that tradition than the coming of self-driving cars.
Why can't people abandon the journals that were purchased by text book publishers? If article submission and peer reviewing are completely independent from publishers, creating and migrating to a new journal should be feasible. The PDFs could be distributed via torrents; each author could seed his own work.

Apparently, people would rather submit to abusive high impact journals than help raise the impact factor of open access journals.

In other words: even if mushrooms grow on it, land is not fungible.
Most of that land out West is too dry for many trees. There are some really interesting experiments for improving scrub plant growth using wavy rollers (water collects at bottom of rippled soil), but the fuel to plow that much land would probably do more harm than good.

You don't understand what IEEE floating point numbers are.

IEEE 754 specifies a binary representation. There is no "normal" floating point literal notation. There are numbers in decimal or scientific notation, nothing about which will tell you what kind of internal representation the number should have (not even whether it should be floating point or not). You have to add syntax extensions (this is how Common Lisp does it: http://clhs.lisp.se/Body/02_cbb.htm) or pick an arbitrary representation. Is setting a variable to pick a representation more troublesome or "can go wrong more easily" that setting any other kind of variable for you, or is there something special about that particular variable? You might as well complain that the default Common Lisp reader/printer does not handle C99 hex float literals.

I think a related phenomenon plays a significant role in the current American political divide. Americans whose self-identity is threatened by increasing technology and connectivity make up for the loss by banding together against identifiable groups of others. Whether the opposing party did something to deserve the hostility seems to matter very little. What matters is that they can be blamed enough to facilitate a collective bond against them.

As of now, there's no easy and simple way to write messages on the Ethereum blockchain. MyEtherWallet doesn't count because it's not really something that tech-savvy non-coders can figure out.

Put in a low fee to recoup costs for hosting/domain and also to deter spamming the network. It's easy to circumvent if you know what you're doing though, so it's more of an honour-system thing.

Taiwan was a Japanese colony for 50 years and Japan deliberately "westernized" the local political and industrial culture. Whereas elsewhere the Japanese didn't see the locals as fit for modernization and so didn't bother. The KMT were beneficiaries of this when they took over the island, even though they implemented a program of sinicization.

Lee Kuan Yew famously fashioned Singaporean culture almost out of whole cloth as he believed that without a radical transformation in the social and economic culture that Singapore would quickly disintegrate. I can't find good quotes at the moment, but he had some really harsh opinions about the local ethnic Chinese culture from which he emerged; that it was corrupt, chaotic, criminal and an existential threat to the new nation.

Sort of. But the "Average Mac selling price (4q average)" is an abysmal chart. The first-glance takeaway is, "Wow! The average Mac price has almost quadrupled recently!" when in reality it has increased about $150, or about 12% from two years ago.

I was just thinking today - I read easily, but alphabetizing is relatively difficult. I'm trying to alphabetize some things, and I'm repeating the first few letters in my mind. Words and spellings are correlated in my head, but when I read I'm not automatically working with the letters; it takes work to produce them. I also sometimes have a momentary inability to compare letters, so I have to recall part of the alphabet in sequence to locate myself. Like, say, I suddenly can't remember whether "I" or "M" comes first until I run through "IJKLM".

I don't think I am or have been dyslexic, but I have no point of comparison.
If we leave it up to the free market to decide how they should be deployed and regulated it'll be a shitshow, no doubt about that. Of course, our roads are already a shitshow, because we let the car industry decide how we should design our cities, and then enshrined the resulting dysfunctions in law.

Waymo at least is signalling responsible deployment, they announced today a partnership with the Phoenix Valley transit authority to help encourage greater transit use.

One valid point they made was that while mass transit is great in high demand areas and along major transit corridors, out on the feeder routed the suburban sprawl it isn't so effective. Service is infrequent and off-peak busses run mostly empty. Robotaxis will be great for getting suburbanites from their homes to major transit hubs.

The 27" 5k iMac is the best Desktop I've ever owned - don't think there's anything else that comes close to that build quality + form factor. Monitor is gorgeous and performance is fantastic.

Personally I consider the USD $1,799.00 starting price great value for the 27" 5K iMac, although as I hang on them for a few years I always get the CPU upgrade + SSD options and always buy RAM elsewhere (where it's much better value).

I'm also a late 2013 MBP hold out who was waiting for a great MBP option to upgrade to, but didn't find the latest MBP's was compelling enough to upgrade to so got a 5k iMac instead, glad I did.
Its simple: opportunity cost.

If a testing plan was going to accelerate the adoption of autonomous cars which are twice as safe as human drivers by one month it would save the lives of approximately 40,000/2 / 12 = 1,666.6 people. To stop the aforementioned testing plan because it is expected to kill 1, 10, or even 100 people will increase the expected number of premature deaths.

There is of course an optimum between training deaths vs. future lives saved, accounting for uncertainty, and etc. but the number of expected training deaths will never be zero and considering the large number of future deaths currently expected, the optimum is likely to be much higher than zero.
If you're a vim user the touch bar mbp is pretty much a no-go.

Yes, it's a passage in the Republic that I'm particularly thinking of. I have only the vaguest memory now, something like that only a few of the oldest and wisest should be told the real reasons for rules, and the rest should get various levels of cover stories?

Agreed that there's a deliberate indirection in dialogs; that's why I included the caveat. But to take another example, the Turtle is not always Hoftstadter's mouthpiece, yet Hofstadter doesn't seem especially manipulative to me. Plato (at least in translation) does. The passage I brought up just crystallized that reaction. I started out reading Plato from the usual charitable standpoint, and ended feeling that's a mistake: whatever's he's up to, it's not primarily to help the reader become a better independent thinker, or to accurately report events.

I've read less Aristotle, but he gives a different impression: someone with faults like overconfidence, but who's honestly pitching in to the project of improving collective knowledge and thinking.
I went from the top-spec 2012 rMBP to the 2017, and was surprised just how small the performance difference was. Most of it was in the GPU (e.g. the 2012 struggled to play a video on an external monitor while working). The 2017 gets a lot less hot/throttles down less often too.
Yeah. I got my link from the Amazon "share" button. Apparently "a.co" is Amazon, but it does look obfuscated doesn't it?
My theory is that parents who drive their kids to school stay on the streets to do chores. This puts a lot more traffic on the roads at peak traffic times. During the summer, these extra people spread their chores out during the day. Thus, per day, the car total on the road is approximately the same during school, and not, but school hours change the distribution, and the school distribution is exponentially worse.
It's only 3.5 hours from Seattle in the summer when Washington Pass is open and about 5 hours in the winter. Beautiful and worth a weekend visit.
Land and not housing is a positional good, but socializing it can help reduce the effects.

Density only actually needs to be very high for a very, very tiny fraction of land. In SF, for instance, something like 80% of the land is zoned exclusively for single-family homes. You don't need elevators nor steel-frame construction to build 3-4 units where there previously was 1. A very substantial amount of inexpensive housing can be built where zoning currently disallows it. As you said though, transit becomes the next bottleneck.
There is no “energy problem”. Energy spent mining bitcoin is the price paid for security of the ledger in in-cheatable currency of the universe. Proof of stake systems are all castles in the air in that regard.
I think the car analogy is flawed; yes, mid-century US cars were not very economical/efficient, but they sacrificed that for comfort --- big roomy interiors, cushy seats, soft suspensions, automatic transmissions, A/C, etc. The automakers were simply obliging to please customers with these features. There's a reason "econobox" is mostly a pejorative.

In the 90's I cared about Apple not dying because I loved the Mac. Apple dying or discontinuing the Mac are the same thing to me. I would be fine with an Android instead of an iPhone, the difference there just isn't that big to me. OTOH every time I try Windows it makes me want to throw the thing out the window.
The whole forest doesn't die at once, the dead trees' biomass doesn't all break down at once, and said biomass largely gets incorporated into new seedlings that spring up in the now-open space.
>Cattle grazing, thought it isn’t an ecological disaster like dam building, is quite different than leaving the land untouched.

Leaving the land untouched is even more 'ecologically privileged' than using it to make expensive food.

>Plus, a good portion of the country’s good farmland is diverted to growing feed for those animals.

Growing feed (hay/grass) is much easier than growing things like almonds. If a farmer could grow something humans would pay for directly rather than hay, they would.
And when I first got online in the early 90's, my ISP had an additional subscription option to get real newspaper-type articles delivered in a special usenet newsgroup hierarchy (can't remember the name of the news service itself though).
>> I miss the old Apple.

Depends on what you mean by "old".

I was an Apple user from the mid 80s starting with the Apple //c. Moved from a IIgs to a Mac SE and a bunch of Macs in-between before switching to Windows in 97 and back to Mac in 05. The most expensive Mac I ever bought was a Powerbook 170 which was a whopping $4K CAD (in 1991 dollars), even with a friend's Apple employee discount. I also had a couple of Newtons along the way.

The second most expensive Mac I ever bought was an early 2011 15" Macbook Pro (yeah, that one), and that didn't end well for me. It was the first laptop I ever had of any brand that just up and died. It happened just after my AppleCare lapsed, but before they issued the repair order. That soured me on Apple for good, and I haven't looked back since.

I don't miss the "old" Apple. In my mind, Peak Apple was 2012, pre-Retina Macbook Pro. Macs in 2012 were still relatively user serviceable while being reasonably compact.
