Well, Milton Keynes was built incrementally as people arrived to fill it, and it and the other new towns definitely had an economic reason to exist - the existing towns couldn't handle increasing urbanisation and the growth of businesses that relied on that. It did end up with rather more light industrial space and slightly more offices than necessary due to the decline of British industry, but nothing like the kind of speculative building described here.

I don't think such mass speculative building would even have been economically possible; if I remember rightly, the housing construction was done by the usual home-building companies who needed to be able to sell off their houses to residents in order to afford the next tranche.

Great job SpaceX!!!

So proud of them for pushing human space exploration forward.
Going for 4 for 4! Let’s not forget the successful payload orbit insertion. :-) We’ll see in ~15 minutes. Edit: Congrats SpaceX!
Omg, this is awesome. I love this quote:

> "You don't count what day it is when counting days, I just explained that. If today is SATURDAY, it's not 2 days until SUNDAY now is it?"

The sheer concept that Sunday to Sunday = 1 week versus Sunday to Saturday = 1 week is kind of bending my brain.
I think it's not a good idea to talk about them as one thing and the use cases also differ. `const fn`s are deterministic ("pure") functions that can be evaluated at compile time if all arguments provided also can. `const A: B` generics are about compile-time value dependent typing. The former is important for the expressiveness of the latter but they are ultimately independent. Moreover, the implementation effort is also mostly independent (different people are doing the effort). Even having them in the same WG might not be a good idea.
I can't think of anything that beats the dual hoverslam for cool factor. What a breathtaking sight! Mad props to Elon and the team at SpaceX for getting the hat trick.

If Mozilla is a "bloated non profit" then they have no constitutional obligation to defend Gab's free speech. When you act like tech companies have the obligation to promote free speech you're actually giving them more legitimacy than they deserve because you implicitly accepted the idea that if speech isn't being propagated by them then it's impossible for it to spread.

In my opinion, Assange lost his moral high ground after it came out that he was communicating with Trump Jr. and helping the Trump campaign. And that he delayed and timed the DNC and Podesta leaks to cause maximum advantage to Trump, instead of just releasing them when ready.

Not to mention that DNC and Podesta were private entities, not government officials and zero illegality was revealed by those leaks. He later was asking Trump Jr to ask Trump to recommend himself as the Aussie ambassador to the US as payment for helping Trump win.
Thank you for your insightful comment!

I agree, people do choose a database based on its track record, and this is where EdgeDB will have to prove itself. Overall, I think that the decision to build on PostgreSQL is a great competitive advantage over other new databases: we can confidently say that the data will be safe with EdgeDB. And we can actually spend more time improving the ergonomics of the data model and the query language.
Can engineers please critique the following idea:

Design city size "Spidercam" style delivery systems
https://www.youtube.com/watch?v=dDGAa6ww7S4

3-4 tall pylons with heavy duty winches and kevlar cable linked in the middle to hold a winch system that can lower a delivery box anywhere in the city.

1/4 inch kevlar rope weighs 2lb per 100ft, therefore a 2 mile kevlar rope would weigh 210lbs, but has a load bearing capacity of 9500lbs. So this system would allow accurate delivery anywhere in a 2mile x 2 mile area.

Potentially these could be coupled to allow transfer between areas to allow deliveries to be passed along a chain.

Multiple winches could be stacked on pylons to allow multiple sets of ropes, with winches which are near to delivery/pickup points moved downwards and to lower rope tension to avoid other winches/ropes bumping into them.

We already limit astronauts and many other professions based on genetic properties: height, tollerance to high g-forces, eyesight etc. Even things used as health indicators like resting blood pressure are influenced to a significant degree by genetics.

I think we will survive adding a few more genetic properties to the job requirements, especially since jobs on planets will vastly outnumber jobs in outer space for the forseeable future.

Because sensors aren’t the hard part. We already have enough hardware to perform superhuman sensing but it’s meaningless without the massive amounts of mapping data and trained models to make sense of it.

Just watched the boosters come down on the Cape from near Cape Canaveral National Seashore. Amazing to watch be able to see the separation, boostback burn and landing burns with my own eyes. Beautiful and eerie sight.
In terms of use-cases, we see things differently from a product like Athena. We are focused on ETL-free real-time analytics and applications which make use of the fact that we construct multiple indexes automatically behind the scenes to enable low latency and scalable query serving.
what, exactly, is the problem with having “newblockbuster-movie.com” ? These sort of domains are usually abandoned within a couple years, anyway.

The drone ship does what it can to be as stationary as possible but the swell will always move the platform to some extent so the ocean landings are a lot more impressive than the land based ones.
I mean exponentially as in the experience is radically different. VW, BMW, etc will disengage multiple times during a trip by itself. Autopilot does not. 99% of my trips, I do not have to take over from autopilot. It just works. Sharp curves, stop and go traffic. The intelligence of the system - Tesla will look at cars in adjacent lanes, detect a blinker and slow the car to allow a merge. Tesla will look at cars approaching from an on-ramp merge and slow down to properly zipper merge. Tesla will detect a car in a blind spot during a lane change and automatically steer to avoid a collision. And yes the automatic lane changes are even further. They don't require perfect road conditions and there are no issues with proper speed or accurate changes. For me in SoCal traffic, the car will drive onramp to offramp, changing highways and avoiding slow traffic without me doing anything. This is what I mean by exponentially different. It is night and day.
> they were eventually filled

Which may or may not be true, but what you really want to know is what is the total value of property there vs. the total value of loans issued against it.

If they were only able to fill it by exploiting favorable central bank policies, all they've done is kick the can down the road.

Revealing unknown facts is a political act. It never occurs inside a vacuum. While it's frequently a good thing, the sort of broad statements you're making about politicians making criminals out of the 'good guys' just doesn't represent the political facts.

Assange almost certainly had access to hacked information related to both the DNC and the RNC[0]. Only the DNC hacked info got released. Are we supposed to thank him for withholding just the proper amount of information for us to make our voting decision? Or can we admit that he had an agenda in all of this that didn't align with the best interests of the American people?

Lucky you! Consider me slightly jealous, I have to do with the youtube feed, but I have yet to miss a launch. This one kept me up way past my bedtime but it was so worth it :)
The sonic booms were lovely as well! Gives you somewhat of a sense on how fast they were coming down.
> "where uber is not allowed or limited"

Doesn't that strengthen the argument for the network effect? The only places there have been successful 3rd party launches are in markets without Uber or Lyft, where there is no network effect to compete against.
I don't think that most people realise what an achievement this is. This is major, three boosters landing simultaneously and one of them is landing on a moving object in the middle of the ocean. And they will reuse the two side boosters for the next FH launch.
The exterior algebra by itself is not enough for physics, since it doesn’t “know” about the inner product, and so it cannot tell when vectors or wedges should be perpendicular.

Given the inner product, you can define the “hodge star”, which restores this information. Another way of restoring the information is to use a modification of the exterior algebra, where rather than having the product uv = u wedge v, we deform the product by setting uv = u wedge v + <u, v>. This is called a Clifford algebra [1], and when the input vector space is R^3 and the input inner product is the Euclidean dot product, this Clifford algebras is exactly the “geometric algebra”.

I prefer to read about Clifford algebras, because the language is much less sensationalistic than many of the articles I’ve seen on geometric algebra. It also generalises to not just inner products, but any symmetric bilinear form, such as the Minkowski form on R^4 which is used in the study of relativity.

In the days before the Internet you sold customers whatever you wanted, they did not know that there was a universe of choices out there. This was particularly the case in small towns and Tandy were in a lot of small towns.

Sure there were magazines, but, think of other stuff people bought back then, the local retailer was influential. The better products can be held off for quite a few years by a strong retailer presence. Maplin in the UK managed it for quite a few years in having a High Street presence selling so-so stuff.

There were also limits to how dealerships in better products could sell, you might have had to have gone to a different town to see a PCjr, they might have not been able to mail order it to you as that would be competing against rival shops and their respective areas. Plus the brand would not be able to sell mail order as they had good faith to keep with the dealer network.

In this way computer interested folk would get suckered into buying the Tandy products, having the local shop for support, showroom appearances, sales staff patter, a warranty, it all helps.

Amstrad in the UK had a business model at the time remarkably similar to the Tandy computer one - okayish hardware, not cutting edge, packaged well.
True freedom of speech ultimately comes from a society's culture and morality not a law. The 1st Amendment doesn't mean much if the powerful can harass and intimidate its opponents into silence while still remaining in the technical letter of the law. Just like you'd probably wouldn't like it if women were denied employment opportunities because only 'men were created equal' How is this such a hard concept for liberals, the supposed founders of the 'Free Speech Movement' to understand?
I am not alone on that then!
> volunteer staff

Why would some people work for free so that drivers can earn more or riders could pay less?

Uber racked up a $20 billion cumulative deficit by subsidizing both drivers and riders.

Even if you cloned the Uber app and had people volunteer to do customer support, you'd still wind up with a service where riders pay more, or drivers earn less, or both.

That works for BlaBlaCar [0] that's true carpooling, without drivers trying to make a living on the platform. Riders pay less and drivers get paid less.

But if Uber is losing $4 billion a year at the current prices, it's hard to see how there would be a sustainable market where drivers make more and riders pay less.

Why does Keybase allow a single remote identity to link to multiple Keybase accounts, but does not allow one Keybase account to link to multiple remote identities (on the same service)? If I run multiple Twitter accounts, I don't see why I shouldn't be able to link them all to my Keybase profile.

As far as I understood WikiLeaks was purely a publishing platform. Not sure if this is the case back then but they have had claimed anonymity through the submission process (via proxies, and encryption)... to protect both themselves and whistle blowers.

If all they were doing was publishing... that should be protected by first amendment.

If Assange conspired with manning that would be a different story, but it doesn't seem to be the case.

I have a lot of issues with Assange, particularly as it pertains to Wikileaks handling of the DNC leaks, and Assange's collaboration with nationalist parties around the world... but despite my distaste for the guy...in this case I don't think he committed a crime.

"Arguing for closed source by default is contrary to that, in my opinion."

I didn't, and never have ;)

It's mostly the opposite, which is that i usually am the person telling people to open source things by default.

Here, there turn out to be IMHO good reasons not to open source it at the start (it will be eventually).

The counter argument of "Google makes billions and they can certainly afford to do X" always seems to be a bit silly to me, since companies are made of people and not money, not to mention that most things companies open source will not be driving revenue in any meaningful way (again, some does, but it's the minority of open source for most companies). Open source is more of a development methodology than a sane economic model.

I've also changed over the years. After watching open source try to create a lot of products, these days i would definitely rather see good products than open source ones. Those things are 100% not mutually exclusive by any means, and in an ideal state you don't have to prioritize or choose between them. However it does mean that when i have to prioritize my choices, i'd rather have people concentrate on making good stuff than open source stuff. To start. In the end, i'd like it all to be open source :)

Others are different for sure.
Employees saw their share price go from $44 in June (private markets) to a range of $62-68 during the road show last month to an IPO at $72, to close today at $61.

Again, in less than a year, rose from $44 to $61 with a brief uptick to $72 in the middle.

How is that plummeting?
>>It's interesting the amount of adjusting it takes for you as pedestrian to get used to which side to make sure to look to before crossing

You should always look both ways regardless of which side a car is driving on. Reason is that bicycles sometimes drive in the opposite direction as cars. Also, sometimes cars, for whatever reason, will drive in reverse.
I've been in the tech community in Asia for 5~ years and traveled a lot around the area including to Singapore. The engineers I've met definitely do not want to move to Singapore.
The folks at magicstack have written some seriously cool libraries. Lots of neat cython stuff, postgres, libuv, http parsing. I really like reading their code.
Luckily, I heard about it on the radio on the way home from work and got home a couple minutes before the launch, so I could watch it from my front yard.
Keep in mind that the boosters flip around and initiate a burn to get back over land. As far as i'm aware, the core maintains a primarily ballistic trajectory and thus lands out in the ocean.
Any miscers checking in?
It's worth noting that hydrogen is orders of magnitude more energy-dense, by mass, than lithium-ion batteries.

As a benchmark: the DJI Phantom weighs roughly 1kg, and its battery can store about 80kJ of electrical energy. I found a NASA study [1] which estimated that the energy released when a li-ion battery combusts is roughly 2x the usable energy capacity. So let's say that a battery fire would release 160kJ of energy.

In contrast, a balloon capable of lifting a 1kg drone would need about 830 liters of hydrogen, with a mass of 75 grams. That amount of hydrogen, if burned in room-temperature air, would release about 9MJ -- roughly 50x as much energy as a battery failure.

(Of course, most of the hydrogen would burn itself up quickly and harmlessly, assuming the balloon isn't flying near any flammable objects.)

There is no sign at Gab saying 'no commies allowed' At its core, Gab itself is apolitical or at least far more so than its rivals. The left are welcome to use it as much as the right. The main difference is that Gab allows more freedom in many respects, which apparently is a rightwing thing to some people.
Ideally, yes. If you need to preserve the ability to get refunds earlier than April 15 then one of two things needs to happen:

1. Move up the deadline for companies to submit tax information to the IRS, or

2. Allow taxpayers to declare that the IRS will not receive any more tax information than what they already have, with penalties for lying (presumably, the same penalties as what happens today if you submit your taxes early and you yourself haven't received all the relevant information yet).

Or we could just pay the one-time hit of "you can't get your refund early" and have the IRS process taxes once the existing deadline has passed for companies submitting tax information to the IRS. I say one-time hit because after the first time, any refunds for following years would occur 1 year after the previous year's refund, just like it does today, it would just be at a different point in the year (assuming you even submitted taxes early to begin with; if you didn't, then no change).

Interesting S-1. I was actually kinda bearish on Uber in terms of scale for future growth/profit opportunities, compared to Lyft, but now I feel like Uber has the upper hand.

Yes, profitability is a big piece, but Uber is more diversified, in that they have other rev streams - Food Delivery and Freight, which they are ramping up (Focused on growth for now).

Also, by way of partnerships/equity, they have stakes in a lot of different market leaders in other markets/geographies. These companies are further diversified in terms of other rev streams (payments, commerce, food delivery etc).

Not sure how much of that is captured in the valuation.

SDCs (L5) are definitely a ways off in terms of becoming ubiquitous. Companies are doing fixed route or city/geo-fenced testing and for any of these companies to actually get to Uber's scale will take a long time and maybe Uber can acquire/partner with one/more of these before that happens.

Also, if we consider ride sharing as a commodity, Uber benefits from economies of scale as opposed to other competitors who may operate in smaller regions/markets so that's also going in their favor.

All of this is to say, they are definitely focusing on growth for now (which there is a lot of opportunity for), but at a certain point they could probably start becoming profitable by either reducing costs or ramping up prices (in tiny percentages) and still be better than the alternative.
