But 110 m/s - that's 396 km/h or 246 mph - about the speed of a high speed train in Asia or Europe, give or take. And that is when the pods are empty. Sure, without the friction of the rails and the air you save energy, and maybe you can build the whole thing cheaper, and that's lovely and all.

But wasn't the ambition to go much faster than a train? I thought this was about reaching speeds of airplanes...

If we are at speeds around or below 200 mph when the pods are full, SF - LA would still take a couple of hours. A French wheeled TGV could have done that 35 years ago. A Japanese wheeled Shinkansen could have done that even before. A Japanese or Chinese maglev version of the last 1-2 decades could easily beat that. And that's without being stuck in a dumb tube. By the time the hyperloop becomes a reality, if ever, there will be tens of thousands of miles of high speed rails around the world.

The hyperloop is a sizeable amount of current hype and a future loop with pods that barely match yesterday's high speed trains. These high speed trains, engineering wonders that actually exist, don't receive any attention in press. I'd say that the hyperloop has been remarkably good at sucking the air out of the room.

Icelander here, I'm more concerned how well does this house work in icelandic conditions? Does it handle earthquakes well? What about regular storms? Being wet for months end? Constant freezing and thawing? Can you put it in an active volcano? Does if float on magma? There are lot of questions here!
One thing that I like about CBOR is that with very little knowledge it's surprisingly readable in a hex-dump. Low value positive integers are the value of the byte itself, strings all have the form "0x6L [string]" or "0x7X [len] [string]". Arrays and maps are similarly obvious.

Of course, anything more than a simple construct you're better off using a decoder (e.g. a Wireshark one).

Also, the fact that it's compatible with JSON means that you can use JSON in your development, and then switch to CBOR at the end for the reduction in packet size. In python it's as simple as changing:

import json as encoder

to

import cbor as encoder

>Rent does not build wealth. Rent is the act of transferring wealth from the poor to the rich.

That's not a general rule. It really depends on rents, interest rates, and the cost to purchase housing. In a functioning market rents bring in just a tiny bit more than the monthly mortgage payment, including taxes and fees. There have been times in my area where you came out ahead renting, and times when you came out ahead owning.

The government makes a terrible mistake when it pushes home ownership for people who cant afford it. In the US home ownership is a characteristic of the middle class, not a cause. It's as much consumption as it is savings.

A friend of mine does that, but there are a few problems with that model:

- it's harder than you think and a lot of work to find new customers

- customers usually want more than "just a website"; you also need to offer things like newsletters, online reservation, etc.

- if you get enough customers to make it worthwhile, you will be get lots of support requests

> This is not an issue with Go because everything is compiled to an x86_64 binary there

I don't think the situation is all that different. All the Java code ends up being binary as well, at least after running a while.

At the moment, I think most people's Go projects simply have fewer dependencies. If you poke about on some of the popular Go projects, you'll see some of the bad coding practices that will result in upgrade breakages like checking for exact error strings (unfortunately needed sometimes, I know), so I foresee the same issues over time.
My point is what is the real cost of living in this house, can the folks living under the poverty live really afford to live in it?
Indeed. My house is 20 minutes away from the centre of one of the financial capitals of the world. You couldn't buy enough land to build one of those houses on for half a million. You wouldn't get planning permission anyway, and I doubt it meets the local building regulations.
> "If… you have 'binders of lore' and no book... you’re living with serious Idea Debt."

Moving from a daydream to some actual artefacts the first step _away_ from Idea Debt, not further into it.
In technical terms, this could be writing a script instead of building an application or creating a spec and some documentation before writing some code. I'd argue that this is where you start to flesh-out and make real your idea.

Binders of "lore" would be an amazing resource to have at hand when you actually do come to writing your book. Surely this isn't a waste of time but it's where the idea ruminates, develops and matures. If anything, it improves the quality of an idea and can help make that idea a reality.
It doesn't look very sturdy, which seems to be a wrong assumption on my part [1], but 20k for a decent house is nice...assuming you own the land already.
For comparison, how much do the Amish-houses cost (materials) and how long do they take to build them? I only know them from movies but they seem like low-cost/quickbuild type houses, too.

Edit: Building instructions for this could be a good application for a VR-based tutorial :)

[1]: "They're built more like airplanes than houses, which allows us to have them far exceed structural requirements. ... We're using material much more efficiently. But the problem is your local code official doesn't understand that. They look at the documents, and the house is immediately denied a permit simply because the code officials didn't understand it."
The nice thing about a cheaper house is you then have more money to spend on a better plot of land.
It's been tried a few times... Probably the best challenge was the USFL, but they couldn't make a go of it over the long term, and that was when the NFL media machine was much less entrenched.

I moved from algorithmic optimisation and old fashioned stats and computer science into data science, I was mostly shoehorned into it back when it wasn't hot.

The money is ok, but the problems you solve tend to be extremely inane and unfulfilling, mostly having to do with clicks, products, and how to divert people's attention to generate revenue. Sometimes I really feel I am just contributing to the evil of the world.

There is an emerging market for data science into energy, one of the few industries where you can do some good. I have been trying to move into it but seems DS is extremely tied to web and finance...

I would stay in physics if I was you, it is an intrinsically beautiful science along with mathematics.

Disclaimer: I will leave the field soon and dedicate myself to bug farming, among other projects.
Material cost of houses is already 'cheap'.

But you also need a place to build it. In The Netherlands ground prices range from $100 - $500 per m².

Then you need sewage, electricity, gas, labor, and so on. I don't think you could make those much cheaper.

How Nix solved the issue:

1. Each go package has an attribute name in nix, like anything else, that is not tied to its url.

2. Each go package has an url where to fetch the source from, which is not the import path to use the package.

3. Each go package has a number of old import url aliases (e.g. "code.google.com/...")

4. Whenever a package X depends on Y with an old import url, then X is rewritten to use the new url path of Y using govers.

So the problem is solved at our packaging level.

This is not to say it's the best solution, but certainly a good alternative solution.
I think people generally think luck is more of a factor in success than it is, rather than it being under-appreciated as you claimed.

You might think there's some luck in joining Google in 2001, but that ignores a prior decade spent on information retrieval, which was VERY MUCH NOT a hot CS field -- it was arguably the opposite. It's not luck when you spent huge amounts of time on something you care about, but other people don't care about. And when you happen to join some like-minded people well before they were successful.

There are also plenty of brilliant people who also joined Google in 2001 who never became VP of search. Based on that, I'm saying there is NO possibility that he doesn't have extreme talent. You don't get to the top at Google accidentally.

Extreme success obviously involves both luck and talent, but luck isn't that much of it. Bill Gates got lucky in many ways, but he would have been tremendously successful no matter what. To a lesser degree, I'm sure the same is true of Amit.

If he wasn't viewed as a top student, well that means diddly squat and isn't surprising at all. Contrary to the grandparent, I would NOT expect the top students in the class to become the most successful. People who overoptimize for academic success are generally somewhat obedient... Early engineers who become VPs, founders, and other successful people are not obedient (whatever their other flaws).

This is a really old argument too, which your comment isn't really doing justice.

I really don't get this at all. The JVM is a program. It sits in a single directory. I routinely have several installed on my laptop. There are no operational complexities from having multiple different versions installed, if you want that.

I suspect this really boils down to operational complexities of Linux distros, not Java. If your package manager only lets you install one JVM then maybe this seems "complicated" relative to Go, but that's not a Java problem.

WRT the standard library, yes the Java standard library doesn't expose UNIX specific syscalls. It exposes stuff at a higher level instead because it tries to be portable. That's a different tradeoff to what Go makes but I wouldn't say that makes it badly written. To me badly written would mean buggy, confusingly designed, too small or too big etc. If you want to write non-portable software then that means you may have to link in an extra library or so (like JNA).

Creating sockets does not do DNS lookups in Java. You may be thinking of the URL class, which does, and there's a URI class that avoids that.
Building something on land that isn't standard reduces the value of the land because it has to be removed as annoying.

Undeveloped land is risky to finance because you have no idea how the borrower will develop it. There are a lot of whacky people out there.
GoPro to axe low-end action cameras
I used to have ideas on a to-do list, but it was torturing me (especially as it takes a few orders of magnitude to come up with an idea, however elaborate, than to do it; and doing it is also a reality check - some things seam clever until you start doing it and meeting contradictions).

Now it is a separate list, entitled "n-th-priority-tasks-tml.md". And I try to keep no regret for not doing things.

For doing, as cheap as it may sound "just do it". As I heard from one writer "Imperfect books have one advantage: they exist". (At least for me perfectionism is the prime reason for delaying such projects.)

And one advice from a friend of mine, when I was delaying (for 2 years) writing a quantum game (http://quantumgame.io, coming this March!): "the only thing you lack is sitting on your ass and writing code". She was right.

Point taken, but I still think that the device should be protected against supplying it with a "malicious" input voltage, as there are cheap and robust components to do this. The NCP373 for example (http://www.onsemi.com/pub_link/Collateral/NCP373-D.PDF) protects against voltages between -30 to 30 V and is designed exactly with the "faulty USB cable" use case in mind, and the low-volume cost is just 50 cents (large-volume cost is probably much lower). So I think there really is no excuse for letting a faulty 5 $ USB cable destroy your 1000 - 2000 $ device, even if it supplies an input voltage of the wrong polarity.
So, the US favours owning residences because renters have nigh zero legal protection?
Experience with C/C++ is exactly why people tend to value compaction. I've absolutely encountered servers and other long-lived apps written in C++ that suffer from heap fragmentation, and required serious attention from skilled developers to try and fix things (sometimes by adding or removing fields from structures). It can be a huge time sink because the code isn't actually buggy and the problem is often not easily localised to one section of code. It's not common that you encounter big firefighting efforts though, because often for a server it's easier to just restart it in this sort of situation.

As an example, Windows has a special malloc called the "low fragmentation heap" specifically to help fight this kind of problem - if fragmentation was never an issue in practice, such a feature would not exist.

CMS was never designed for 100GB+ heaps so I am not surprised your experience was poor. G1 can handle such heaps although the Intel/HBase presentation suggested aiming for more like 100msec pause times is reasonable there.

The main thing I'd guess you have to watch out for with huge Go heaps is how long it takes to complete a collection. If it's really scanning the entire heap in each collection then I'd guess you can outrun the GC quite easily if your allocation rate is high.

Flats usually suck because you have noise from neighbors. Of course, you can build flats with better sound insulation, but that obviously costs more, although I'm not sure how much more.

I chose the name "ideas" instead of "n-th-priority-tasks" to clearly distinguish this list from actual tasks. Because they aren't. None of those entries deserves to be named "task", until one starts to get serious about them and creates a prototype. And this will happen only to a tiny fraction of those entries.

News flash: being a public figure attracts attention and some of that attention is negative.

I just don't see what the problem is. If you don't want negative attention, don't be a public figure. I can say random stuff on Twitter because I have ~300 followers—even if every single one of them tweeted at me, it wouldn't matter.

Obviously the reason that Mallory got a bunch of repetitive responses to her tweet is because she has 64k followers.

The rank-and-file football player, arguably, is underpaid, particularly in comparison to their colleagues in MLB or the NBA. I think the median salary for non-rookie deal NBA players is north of $5 million/year now. Baseball is similarly outrageous for veterans that reach free agency (the Red Flops were handing out $10 million deals like candy the last couple of years). Not to mention that those deals are guaranteed, unlike the NFL, where players are routinely cut when injured or just before they reach thresholds where bonuses kick in. s
