You neglect the friction that even laminar flow would experience while flowing into the tube.

If you make small fins at the top of the tube you can even exagerate the effect and introduce turbulence, which further reduces flow rate.

There is a reason why pipelines need pumping stations every couple miles, to keep the fluid at speed.

Sure the wave might propagate at the speed of sound but that doesn't matter much if its pressure gradient is slow enough.

To give a good analogy:
Electricity also travels at the speed of light through a cable, however due to resistance you will get different current reading depending on where you measure.

Edit2:
I reread your argument, and there is also a flaw in your energy calculation.
The energy per time is not proportional to the length of the tunnel, but proportional to the size of the inlet.

Your calculation would be if you remove the entire top of the tunnel at once, over it's entire length.
The article doesnt really give you a sense of what the frustration is until you look at a map. I'm surprised it's not in the article.

one of the things rail can do that an airliner increasingly cant do. is land downtown. maybe this hyperloop thing has a chance if its cheaper to build than rail.

not many places have that many 5m+ cities within 500km of each other like china.

Good Advice.

My number one advice is to take it slow learning the language and stick to a safe subset of language features. Focus on what you are trying to express from the problem domain rather than memorizing language constructs.

PS: See Multi-paradigm design for C++ by James Coplien for some ideas.
In the UK everything costs twice as much as originally estimated and takes twice as much time. I hope I will live to experience the 330km/h (operating speed of UK's HS2)
See my above reply.
Speed of sound doesn't mean much if there is a constantly softening gradient.

Even for that there is no need for dynamic typing anymore. This problem has been solves with type parameters (aka generics) and type-classes.
I don't doubt it. At least on non-server machines. They might not even do it intentionally. When every new machine manufactured in the last 20 years has some kind of secure boot system that prevents "unauthorised" operating systems from being installed, what then?

I like this video too. This guy seems to be an urban planner or civil engineer, and he gives some realistic criticism if you can get past the jokes (which are also good)
The problem is that some people will perceive you as weak when you admit having made a mistake, and will exploit that weakness, if only to throw cheap shots when given the chance. It creates a real incentive not to disclose mistakes in the first place.

I live in Calif. and have been watching the HSR debacle.

- You know, the Central Valley "ezpath" wouldn't be such a bad idea if it included a planned city with HSR to relieve SV congestion, rather than just being a "rail to nowhere."

- I like the idea of finishing the HSR terminals in SF and San Jose for long-term use

- I like the idea of blasting through any mountains on the route from SF to LA over time, for long-term use.

Somehow the state is fixated on a trillion dollars or bust right now, which just isn't going to happen.

And state politicians focus on HSR as a jobs program/scam, rather than a transportation project.

The corona lockdown is a great time to work on the San Jose terminal.

I do as well. Which is why I was sad to see mostly comments supporting the new chip without backing it up with more meaningful benchmarks, or being surprised that Apple would put out benchmarks that are half truths in order to sell a product. Neither of these are "news".
Funding for growth is not limited to h/w. SaaS also have similar behaviour, for enterprise sales you burn ~a year of revenue as acquisition cost, so first few you can do as PoC, but beyond that you need sales team and runway which may require funding.

"Train" is decidedly not before the industrial revolution but rather is part of it.

From https://en.wikipedia.org/wiki/Industrial_Revolution

> The Industrial Revolution .. the period from about 1760 to sometime between 1820 and 1840.

From https://en.wikipedia.org/wiki/Steam_locomotive

> Richard Trevithick built the first steam locomotive in 1802.

Further, https://en.wikipedia.org/wiki/History_of_rail_transport :

> William Murdoch produced a working model of a self-propelled steam carriage in [1784].

The definition of "train" meaning "locomotive and the cars coupled to it" dates to 1816 or 1820 - https://www.etymonline.com/word/train .

Let's see Swift when catches up with .NET 5 improvements.

Apple's talk about RC over GC is just marketing speak for the failure to have a tracing GC in Objective-C that wouldn't crash left and right when integrated with C like code.

It was a very sound decision given Cocoa semantics, and the difficulty to make anything written in C not to fall apart with segfaults, but lets not oversell it.

Likewise Swift RC makes sense from having to integrate with Objective-C runtime and existing ecosystem, but again that is all about it.

There is no RC implementation with comparable performance to tracing GC languages that isn't just yet another tracing GC from the amount of runtime support needed to make it actually fast.

(In the U.K. at least) Accident seems to have fallen out of favour as calling something an accident would suggest there’s no blame, which is not normally the case (definitely not in the case).

Pro apparently means it has an extra 100 nits and forced airflow to minimize processor throttling. It only has two serial ports and a small screen, so this was made for field use, though it does have support for a single 6K display when you get (or are confined to) home.

Might be better to go for a System76 or Dell if you can find all the apps you need for them.
I love my T460p, which is a lot like that T440, but a macbook it is not. There are no good macbook pro level screens to be had on those older thinkpads, the trackpad is abysmal, and the machine as a whole is cumbersome to carry around. Also, those 4th gen cpu’s in the T440p are getting long in the tooth, new machines are a lot more snappy (especially single core). On the plus side you have a nice selection of ports (but no thunderbolt) and the best laptop keyboard in the industry, and of course the repairability factor. I’d say that if you’re optimizing for developer comfort, other and newer laptops are better, but getting an older thinkpad is a bit like getting an older car for day to day usage, it is something for enthusiasts or people on a budget who are handy.

The pinebook is somewhat underpowered, if someone is considering a macbook and looking at linux alternatives then a system76 laptop or dell xps developer edition is more up their alley budget-wise and will be a far better experience to actually use.

I think as a community we sort of have to come to terms with the notion that repairability is dead. All modern laptops are basically mostly unrepairable, and when they break the old one gets recycled to component metals and you have to get a new one. On the plus side, they break less often. Repairable laptops in turn are just not as nice to use, so they will keep losing in the market. I only see this changing through regulation that forces a right to repair, but if that means thin and lights like a macbook air can no longer be sold, is that really better?
AMD should easily beat Apple in graphics…

Intel has stagnated itself out of the market, and has lost

Apple’s power efficiency. If Apple’s performance trajectory
continues at this pace, the x86 performance crown might
never be regained.

The real problem here is that you're dealing with a monopoly. Siemens simply has no reason to care, so they don't. It doesn't matter if they build an ICE or a Transrapid, it's not like the DB could switch suppliers.
The problem in Germany is not to travel between major cities. The real issue is if you have to reach a city which is not big enough to be connected to the ICE network, since missing your connection often times means waiting for an hour.

I don't disagree with your take. Xi isn't going to know everything that's going on.

It's just seems odd that it's a speech (and a relatively benign one from a layman's perspective) that set it all off. This was a world record setting IPO and I can't see China's leadership not knowing about it well in advance considering the international media attention it was getting far before it all blew up.

It just feels like there must be a lot more to the story.

Was Jack told he could have his IPO as long as he kept his mouth shut?

Was there something in the speech that directly contradicted what either Jack was told by leadership? Or what leadership had been telling the Chinese financial industry?

Bailouts are a necessary resort when the market fails to self regulate. Which spoiler alert, it has always done cyclically since capitalism is a thing.

The question is not if there will be another crisis, is when it will be. Under a free market, economical crisis are a certainty.
More importantly, there is a false choice between socialism + central planning on one hand, and capitalism + free market on the other.

In fact, all mainstream socialists and Marxists today are in favor of some kind of free market. Also, none of the centrally planned, soviet style economies had any feature of socialism - they were capitalist societies, where all of the power was concentrated in the hands of those who controlled capital. Sure, workers were paid lip service, but their power and control over their work was in fact even less than in the European or American capitalist countries. They were just as much socialist countries as they were democratic - in that it was simply a title they assigned to themselves, void of any meaning whatsoever.

The main difference between an actual socialist market-based economy and the capitalist market-based economy that we have today would be that essentially all enterprises competing on the market would be co-ops, where workers democratically decide how the company is run and get to share the profits (and losses), instead of getting a pre-determined (sometimes negotiated) wage.

The Irish would agree.
USSR, as the country, failed because of central planning. Bailout is not a good solution too, because capital flow from competitive players to incompetent, which is bad for evolution. US banking system is far behind other banking systems because of that.

> It's also build on pylons

High-speed rail can also be built on pylons.[1]

The hyperloop white paper argued that being able to build on pylons would be an advantage of hyperloop over conventional rail:

> The key advantages of a tube vs. a railway track are that it can be built above
the ground on pylons and it can be built in prefabricated sections that are dropped in place and joined with an orbital seam welder. By building it on
pylons, you can almost entirely avoid the need to buy land by following
alongside the mostly very straight California Interstate 5 highway, with only
minor deviations when the highway makes a sharp turn.

The author seemed completely unaware that conventional rail can also use pylons, and can (and does) use prefabricated elements.

The whole white paper seemed terribly uninformed about the realities of high-speed rail.

I learned the hard way that your job is not yours, it's theirs. People say "my job" as if they own that position. Of course this is false, you don't own anything, the employer owns that job/position. Hence he can do as he pleases.

So, are you at the mercy of your employer?, yes you are.
I've noticed when your organisation gets to a certain size, it is inevitable that you will end up working with someone who believes in an "everything is X" fervently enough to do damage. The most common one I've seen is backend developers trying to force frontend to adopt backend paradigms (such as everything is a service, even libraries, and must be communicated to over RPC calls).

They tend not to care about the collateral damage or nuances, they want to order the software according to their beliefs. Once you recognise this you can see the same pattern repeating in a lot of other non-software disciplines. I guess it's just a personality type.
