  1. Re:Explains a lot. on Taxpayer Subsidies To ULA To End · · Score: 2

    If you are referring to the recent delay which caused SpaceX to launch almost a week late and scrap a landing attempt due to an Air Force radar station idiot being trigger happy on the "no go" call, then I agree completely.

    Perhaps MI5 should hire him for penetration testing instead of putting him in jail!

    I think that having inmates penetration test each other is common only in American jails.

  3. Re: Just what the Moon always wanted on NASA's ARM Will Take a Boulder From an Asteroid and Put It In Lunar Orbit · · Score: 1

    Actually, it is pretty much accepted from what I understand that the Moon had several influences on the rise and development of life on this planet, from (among others) stabilizing our spin, to moderating the seasons, deflection of large asteroids, and even to the development of optic cones in addition to rods (or rods in addition to cones, I forget which), etc.

    I think that it was Asimov that pointed out that our Moon follows a fully concave path around the Sun, i.e. never travels backwards, and in his opinion that defined us (for him) as a dual-planet system.

    In order to account for binary systems, I generally look at the central axis of rotation - if it's inside one of the bodies, that body is the 'primary' - IE a planet, sun, whatever. If it's outside, then it's a double system.

    So if the moon were located about 20% further from Earth, then you would consider the Earth-Moon system a binary system?

  5. Re:Cooling on First Nuclear Power Plant Planned In Jordan · · Score: 1

    Hi neighbor! I've been to Aqaba though I haven't dived there. You should know that as an Israeli, I'm very happy to see Jordan building a nuclear power plant. We (humans) need _clean_ energy, even if it is more expensive than burning carbon. And anything that advances the Jordanian standard of living is good for the entire area, especially considering what is happening on Jordan's northern and eastern borders right now.

    The low gravity of Moon would allow the elderly (and other infirm) to remain mobile for many years after they would've become wheelchair-bound on Earth.

    In order to enjoy 0.3 g on the Moon, you need to suffer 3+g for a good ten minutes leaving Earth. I'm not sure that the elderly or infirm will stand for that.

    The Saturn V's actually were one of the slowest-accelerating human-rated craft to ever launch, and they hit a peak of 40 m/s^2, about 4 g, at MECO 1:

  14. Re:Selfies are just a logical extension.... on Major Museums Start Banning Selfie Sticks · · Score: 1

    The odds of another tourist stealing your camera when you ask them to take a picture is pretty much 0%.
    The odds of a someone (especially a poor local) who asks YOU if you would them to take a picture of you
    stealing your camerais pretty much 100%.

    My country (Israel) is full of tourists, and when I see them taking turns photographing each other I offer to photograph the group. I've never stolen a camera, and others do as I do without stealling cameras. I suppose that your advice might be culture-dependent.

    This is the same advice I give my kids. If you get lost, don't
    wait for someone to approach you, instead walk up to the first person you see and ask for help. Most people
    are normal law abiding citizens, if you play the odds and pick someone randomly then your chances of getting
    a criminal are very small. If instead you let them approach you then they are picking you which makes the
    odds of them being a criminal considerably higher.

    That is good advice for kids, and I will in fact start giving it.

    I never implied that systemd is not well tested. I stated that the beta release state is not the state to make major changes in the OS. The feature freeze for this release was one month ago:

    You are blaming the wrong person, if something like Gimp decided to interface with systemd, its the Gimp developers.

    I'm not placing blame, and you are right that it would be Gimp devs who would be responsible for including such a dependency.

    In any case, the assertion that Gimp depends on systemd seems to be rumour anyway. I hope that my GP post gets modded off the page, I have no way to retract it.

  17. Re:ABOUT FUCKING TIME! on Ubuntu To Officially Switch To systemd Next Monday · · Score: 1

    In a hurry? Systemd is almost five years old, distributions have now *years* of experience integrating it.

    Correct. Distros typically integrate software, especially system-critical software, at the beginning of a release cycle. We are now nearing the _end_ of the Ubuntu 15.04 release cycle. I have no problem with including systemd. I do find it unusual that such a critical system component is being swapped out so late in a release cycle. It should have happened three or four months ago for Ubuntu 15.04, or in two months from now for Ubuntu 15.10.

  18. Re:ABOUT FUCKING TIME! on Ubuntu To Officially Switch To systemd Next Monday · · Score: 1

    Gimp doesn't seem to depend on systemd (here is a brief discussion on the topic). It seems to be a rumor, but I don't know where it started.

    Thanks. That link doesn't seem to be much of a discussion, but I'll take your word for it being just a rumour as it certainly does not make much sense that an user-facing app would depend upon any specific init system. We know that there are quite a few rumours about systemd floating about.

  19. Re:ABOUT FUCKING TIME! on Ubuntu To Officially Switch To systemd Next Monday · · Score: 0

    Actually, the stick is the fact that Gimp and some other notable software now depend on systemd. I have no idea why an image manipulation application needs any particular init daemon, but that is the case.

    Interestingly enough, 15.04 is deep into the Beta status and due for release next month. A major change, such as swapping out the init daemon, should be done in Alpha, and far before any Beta release. Certainly not in the month before a release!

    Why is everything connected to systemd pushed out in such a hurry? Why isn't systemd getting proper time for review?

  21. Re:Nuclear ain't cheap any more. on French Nuclear Industry In Turmoil As Manufacturer Buckles · · Score: 1

    The tricky question(and the one that I've been bombarded with vehement and competing answers on, which has left me confused) is whether nuclear isn't cheap; but military procurement slush used to make it look that way; or whether nuclear could have become cheap; but military procurement slush made that unnecessary and potentially even directly inhibited it.

    That is pretty much what happened to the space industry, until SpaceX came along. And until SpaceX came along, nobody would have believed that space could be done both more cheaply _and_ more reliably.
