All ubuntu literature prepends "sudo" to just about everything. I assumed it was standard to invoke root access to do anything of importance in Ubuntu.
That's a dangerous way of thinking, and one of the reasons I hate Ubuntu. What's the importance (if any) of leaving off the "group" in your chown command above?
It's not left off, it's left blank (note the colon). Leaving it blank sets it to the login group of the specified user, which may just be the user itself, or it may be an actual group (the groups command will tell you which). (And leaving the group off entirely (by omitting the colon) will just leave the group set to "root", which isn't what you want at all.) |

Without it I get permission denied errors. I have to do everything in Ubuntu with sudo...
Let me guess, you ran something as root for whatever reason, it created a file owned by root, which means other programs can't access that file, so you ran those programs as root, and you ended up with half your files being owned by root and nothing not running as root will work. Is that pretty much how it went? If so, this should fix it (at the very least you'll need to do it for your Bitcoin data directory): sudo chown -R --from root:root ben: /home/ben It's either that or your path's messed up... |

It's not specifically the energy density that counts, but the thrust-to-mass ratio of the whole package. Based on NASA's test, the device alone (not even counting the power supply) has a thrust-to-mass ratio about 100 times worse than a solar sail, which puts it squarely in the "who cares?" category as far as practical applications go.
Thrust to mass ratio for the sail is measured at what distance from the sun? It falls off with R^2. That's at 1 AU, and further assumes current sail materials. Solar sails could theoretically be made at least 10 times lighter, which would even allow them to compete with ion drives (assuming ion drives aren't also improved in the meantime). |

I am using -daemon to daemonize it. It's the last flag on the command.
D'oh. I need more caffeine, apparently. |

Fun fact: 82% of "facts" are made up on the spot, but only 14% of people know that. Plutonium is the most toxic substance known to man, 1 part per billion will kill.
Case in point. In fact, it is believed to be not much more toxic than lead. I say "believed" because it turns out nobody (not even people who have been exposed to high concentrations of plutonium dust) has ever inhaled or ingested enough plutonium to show symptoms of poisoning, let alone die from it. |

You need to use the -daemon argument to daemonise it. Though, it should exit cleanly on hangup otherwise.

Technical Analysis Analysis Research? Is this where we analyse other people's analyses, and then research the resulting meta-analysis?  |

Not that i'm a conspiracy theorist, but I just have to wonder how you land on the surface of a planet covered in a grey dust that has the consistancy of talcolm powder using high powered rocket engines without kicking up some of that dust onto your shiny metal lander? Even the upturned concave lander feet appear to be devoid of debris.
First of all, the rocket engines are not high powered, as the moon has much lower gravity than Earth. This is also why it took a huge rocket to get to the moon, but only a tiny one to get back. Second, a rocket exhaust in a vacuum is very diffuse, as there's no air resistance to confine it to the narrow cone normally seen in rocket exhaust in an atmosphere. Finally, the dust that is kicked up does not travel anywhere near as far or high in a vacuum as it would in an atmosphere, since there's no wind to carry it. As far as landing on a "powder" surface, sure there would be some powder kicked up, but without any moisture that powder would not stick to any equipment and it would fall right off the landing equipment.
Actually, the opposite is the case. Moon dust is electrically charged, and as a result, sticks to absolutely everything. The Apollo astronauts found that out the hard way. |

This is the labour theory of value, and it is bogus. Just because something is difficult and expensive to produce, does not mean it is valuable.

It is illegal for any US company to refuse fiat payment.
No, it isn't. Whatever gave you that idea? |

OK now as this issue is settled, I get to dissect all your predictions and publish the orange numbers and the leaderboard. Tomorrow!  It's tomorrow. I even gave you the benefit of the doubt and waited an extra second. Where are the orange numbers and the leaderboard? |

But they will continue to accept Russian Ruble, European Euro, Chinese Yuan and Swiss Franc. What does it tell you?
Exactly. They will stop accepting USD does not mean they'll start accepting cryptos. Nothing to see here, move on. Did either of you two actually bother to read the damn statement? Thus, Amagi has planned that by the end of 2016, the company will no longer accept US dollars or other “fiat” currencies. Instead, Amagi plans to be trading exclusively in cryptocurrencies like Bitcoin.

Does bitcointalk.org show up in Google Analytics at all under Referral Traffic source ? It goes under Unknown Source for me.
It oughtn't to. Browsers aren't supposed to send cross-domain Referers from HTTPS sites, since the URL may contain sensitive information (such as session IDs). |

I've never understood what the big deal is with this drive. It does require energy, and nobody sensible is claiming it is reactionless. Sure, using the quantum vacuum as remass is pretty neat, but it's no means a revolutionary idea.

Since when are life forms that originated on Earth "extra-terrestrial"? What about the astronauts? Are they "extra-terrestrial" too? |

I think "special education instructor" is ambiguous in this context.  |
