See my above reply. Speed of sound doesn't mean much if there is a constantly softening gradient. https://en.m.wikipedia.org/wiki/Hagen%E2%80%93Poiseuille_equ... Edit: To give a good analogy: Electricity also trav

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 i

Ok so somebody attacks it, with explosives. And manages to time them well enough that they go off right next to a cart, or inside one. They will get 1 passenger car. Which is what? 8 People? The tube will slowly fill with air, everybody els

Yeah but you have to remember the population density of the us. It's main population centers are west and east coast, with nothing but farmland in between. For them any system needs to be a lot cheaper per mile. Also the only reason wh

Ok let me rephrase, and actually make my point stronger. I'd take a shot at fully funding hyperloop with all the ressources that our current HSR system has, over keeping our ICEs any day. If it was up to me we'd fund Transrapid. I

1 bar is acutally not that bad. Hyoerloop pods are smaller, so less lives are at risk. And most importantly of all. It's not gonna be explosive, unless you rip the thing open with a bomb and you're right next to it. Even if you ri

Trains are what helped spark the industrial revolution, thus by definition they are preindustrial.

German here. ICE sucks majorly. ICE is engineered way over the limitations of the underlying technology. They break down easily and are constantly late. I'd take a hyperloop over an ICE any time. We had good tech, that that didn't

Exactly. But you also seem to miss it. Politicians have no will to fund old technology (and lets face it, high speed rail is PREindustrial tech). However they will fund new shiny technology that they think will make them look good and futur

It's really sad how apple killed their whole app ecosystem with their 99¢ pricing policy. A lot of the apps on there were once mac apps that you'd see on every std installation.

I think Erlangs approach is valuable: fail early and loud. There is no harm done by b), there will never be a costly mistake. If the programmer has to deal with it anyways, at least make them very aware of the fact, they can then still deci

As long as politics are driven by people from law and the humanities we will continue to see absurdities like this. There are too few tech people in politics. Sadly tech people ususally have a low tolerance threshold for bullshit, which mak

I don't see how a distributed system is an "extreme condition". If you don't have distributed ID generation, why not use an auto incrementing u64 and call it a day?

Immigration is NOT the issue. Corrupt government and corporatocracy is. With all those subsidies going to coal, oil, cars, planes and whatnot, we could pay and educate all the immigrants a thousand fold, and make them a super producive labo

The way you get the job done is also an expression of yourself. There is never only one way to do things. The issue is that if you work for a company like SAP, you most likely don't have enough personal flavour to come to interesting o

The fact that you bring up salaries perfectly represents everything wrong with SAP. A job is more than a money maker, it's a platform for expressing yourself. SAP wouldn't understand that though, so they hire the mediocre (to writ

When big banks stop maintaining their cobol bases, then I'll start worrying about the death of cobol. SAP is a backwater for programmers. They're at least 20 years behind the curve.
