I am looking quite forward to that announcement. While other manufacturers have shown some electric semis, they were all in the demo stage. If Tesla manages to get a practical electric semi into production, the impact could be huge.

For those, who think that Tesla should concentrate on the Model 3 first, this is the early product announcement for the semi - production is probably starting in a year only, so there are no real conflicts.

> Building more housing will allow more people to move there

I live in New York. Nobody moves here because they want to live in a nice building that happens to be in New York. They move to New York and then find housing. Demand is largely unaffected by new supply in large cities. Also, I live in the Flatiron neighbourhood. A bunch of new development has held my rent flat for 3 years now. My building tried raising rents; I met a potential tenant looking at a unit on my floor. She went to the new luxury building down the street for his $50 more. My building, facing the new competition, dropped their ask by $100.
While I'm glad they are offering more APIs there will always be a difference between what they decide to offer and basically everything.

> So in the real world, with limited yearly construction, developers' aims will be to build upmarket housing.

I don't understand the line of thinking where this itself is a problem. Who cares what the new housing is, what matters is the total supply of housing. If we build new affordable housing, then lower-middle-class people will move there and upper-middle-class people will move to the older buildings. If we build new upmarket housing, then upper middle class people move there and lower middle class people stay in existing housing.

The problem with building only affordable housing, is that 1. it doesn't seem like you could ever build enough because as soon as you do you create pressure for more people who qualify to move to the city, and 2. there will always be a step function where someone just barely doesn't qualify for affordable housing but can't afford market-rate housing because you've been restricting the supply. Building a lot of both is the only reasonable way forward.

> That's the biggest problem with the US: our cities are just simply too far apart for HSR to be viable in most of the country. And where they aren't, they tend to be in the worst pattern for utilizing HSR effectively.

Naw, the biggest problem is lack of strong centralized authority and planning. The California HSR debacle is a perfect example: death by a thousand cuts. Places like Belmont want to kill HSR with a variety of faux concerns (e.g. opposing electrification and grade separation due to noise concerns). Meanwhile in San Francisco politicians are still bickering over how to extend the tracks to the new transbay terminal (which is currently just a billion dollar bus station). And, of course, the California Republican delegation is trying to tank Caltrain electrification because one of the consequences is that electrification will help HSR. See Also: BART's Oakland Wye clusterfuck.

Or take a look at New York. The high speed train, Acela, is being strangled by Connecticut and MetroNorth. Average speed along the Acela route is 70 mph, give or take.

Meanwhile in Spain, RENFE is second only to China for amount of high speed rail. They're even in the process of switching from Iberian to "standard" gauge track (and even have trains that can switch track gauge without stopping). Meanwhile in New York... Penn station is… a mishmash of electrification projects (Amtrak, LIRR, NJT).

In fact, I think you're putting to much emphasis on time in motion versus time door-to-door. The big advantage that rail has over air travel is that you can build the stations in very central locations. New York is a great example with JFK all the way out in the boonies (unless you live in / are going to Queens) and Penn Station right in midtown. Being able to go from Penn Station to Union station right on the Loop could easily shave an hour off of your travel time... and the hassle of unpacking your bags and taking your shoes off. New York is also at a disadvantage with no easy options to add more flights to either of the New York airports (LGA, JFK).
Indeed. Take for example the City Tunnel in Malmö which finished ahead of time and a million dollars under budget[1]. At Triangeln it has dancing lights on the walls that are somewhat mesmerizing[2].

Bingo!

There is no future where Uber is profitable and there isn't someone with deep pockets who wants to undercut them starting with their most profitable markets.

Most riders don't have much customer loyalty, they just want the cheapest price. Drivers don't mind driving for multiple services.

When a deep pocketed competitor launches with zero market share, they can compete with lower prices. If Uber responds too early, Uber would need to cut down prices on their full market share. If Uber waits too long, the competitor gets more traction.

In the end it is a zero sum game for Uber, unless they could have used their money and focus to create Autonomous Driving Tech. Not sure if that is going to happen now! Their new CEO's mandate is to do the IPO and get investors their return ASAP.

My prediction:

In the next 2 years, Amazon will enter as an Uber competitor starting with Seattle and then slowly expand to Uber's most profitable markets.

Any bets :)

I my college syntax (linguistics) class, most of the teaching was done by the teacher giving us a (carefully curated) set of data to explain as homework.

Class time was spent making sure everyone got to the same answer and understood the arguments behind it. When there are multiple reasonable answers, they also made sure that students understand the other ones and why we rejected them (sometimes the reason is as simple as 'we need to pick an answer, lets just vote'; other times it is 'both are reasonable explanations, the field went with B, read Chomsky 1987 if you want to know why.'). We would then generally talk about problems we still have (especially if the data was English, and students could come up with new data that didn't work as nicely).
That is all good, but what will they do with transportation? When the supply of the housing is increased, it will attract a ton of people who now simply can't afford (as many not-so-top, but still good coders - i know a ton of people who would move in, but can't afford the Valley rent). Can you imaging the traffic then?

It seems a bit odd to export the data in the command line to then work with it in pandas, given that it's a stock sqlite3 database. I'd just use sqlite3.connect and pd.read_sql_query directly.

I call bullshit on the standing seats. "May introduce"...

That's a marketing gag to establish the airline as low budget. Ryanair did the same thing some years ago.

Such seats would need to get approved by the FAA and I'm pretty sure they haven't been.
Same here. If there is a train to go there I’ll pay extra and take the train. Flying sucks so much. It’s not just the airport and the plane. But getting to the airport or back home is also a hassle here in London.
France doesn’t run many trains over the Alps and they aren’t running 200 mph. Geneva to Marseille for example is a pain in the ass trip and driving is always faster, and flying even better.

I don’t think you have any idea how much it costs to run high speed rail lines through the mountains. It’s mind blowing expensive and difficult and the environmentalists seeem to lose their minds. Look at the history of the TGV for examples of how farmers and environmentalists obstructed that project for years.

> other than that which is necessary in a democratic state ruled by law

Well the thing is that is open to interpretation. You can define anything as "necessary".

From what I have heard the typical "foot in the door", if you will, is AML/KYC. There's a convenient intersection there between anti-terrorism (national security) and the everyday (banking). Bring those together and now you have a perfectly plausible excuse to build a biometric database on everyone with a bank account - ie, everyone. And once you've got that DB, wouldn't it be positively remiss not to start using it at the borders?

This is the legal basis of the DB in a certain large asian country you've heard of and, on information and belief, it's being expanded to airports too under the guise of national security. The DB has never been announced or confirmed but its existence can be inferred from KYC banking processes there. The future is now!

> but yet the governments aren't doing it

I would be very surprised if a biometric database doesn't exist in most moderately wealthy countries, even in Poland. They may not (yet) be able to use it legally but knowing the general climate you'd think the various intelligence organisations almost aren't doing their job if they didn't have it.
Typing wasn't the hard part of using shells, either, and yet GUIs have displaced them for many classes of users. One of the very hard parts is "knowing what things you can type." GUIs solved that problem for UI much better than shells did -- it was much easier to discover what the computer could do in an early GUI. A good visual programming language (not that I've seen one yet) could bring similar discoverability to programming.

> If I buy the equipment now I don't have to pay taxes. If I wait I do.

If you wait until the next year, you'll don't have to pay the taxes next year instead of not paying them this year.

But my point is about income vs sales tax:

- 0 % sales tax, 10% income tax:

You don't pay taxes on what you invest (assuming deduction)

- 10 % sales tax, 0% income tax:

You don't pay taxes on what you invest (assuming deduction)

Result: You cannot claim that people are investing more just because you have income tax.

You could of course assume that putting a tax on everything except investment will encourage investment. But it's the same as if you raise the price of everything except water to encourage the consumption of water.

If you ask why this wouldn't work, think about how taxes affect disposable income.

That is simply not true.

Building a CPU can be "easy" if you want to build something that works. If you want to build something that is power efficient and, at the same time, quite performant, then the complexity of the problem escalates very quickly.

Sticking at 30-50 MHz? What is this even supposed to mean? Digital hardware design hardly takes clock speeds into consideration, except during physical implementation in the later stages of the hardware development.

TSMC or Global Foundries will help translating HDL into a reliable node? Do you even know what you are talking about? This "translation" that you refer to is called synthesis and physical implementation and it is done by the design house. The foundry only provided the logic cells their technology and they manufacture the final die that is going to ship on the product.

The CPUs you mentioned were simple micro-controllers, they were not designed for heavy processing tasks, they don't even have a branch predictor which is something fundamental to have some significant performance.

Nothing about your post made any shred of sense in terms of hardware design.

Yea, every time the company fails to work, he shows up, and tells about other mystery projects. I'm not sure how he started to be so trust-worthy, and why people give him loads of money, as he is simply an unrealistic dreamer. And then we hear that the workers in the factories are quite badly treated, and that he personally is the smartest man on the world. This is so ridiculous.

So I suppose he will show some special-ultra-super-hiper-cool project like "cold fusion generator for every house", and people will throw even more money into that black hole. Next year, after all other things he say will not work, he will probably show super ultra Tesla Model Black Hole 5. And he will get even more money.

Saudi Arabia is trying to buy all these assets to secure their future. Returns will likely be reinvested or stashed abroad!

However with the dismal future of oil based economies and the unstable situation in Middle East - only scenario their would be able to retain these assets would be if they are somehow able to transition into a functioning (hopefully democratic), educated and productive society - which would be awesome! It's better for them and the world. I would love it if they are able to use this money to achieve that!

If not they would descend into chaos and all assets would likely be seized by whichever country hosts them. E.g. Gaddafi!

"are physically related such that, in a sense..." I didn't say they were equivalent, I said they were connected. You can't transform a time-like interval into a space-like one, but you can transform one time-like interval into another such that the separation on time increase and the separation in space decreases.

I don't know what to tell you except that more residents equals more property taxes equals more available money to make those investments in infrastructure.
