  1. Re:Reballed? on When You Really, Really Want to Upgrade a Tiny Notebook · · Score: 0

    Reballing I believe refers to the soldering process. Most desktop processors have pins, which are clamped and so therefore easily replicable. In most embedded processors and netbooks, the processor is hard-soldered to the motherboard and therefore very difficult to replace. I think that this is referring to the re-soldering of the processor to the motherboard, or at least re-soldering the connections to the processor "pins" as it were. Correct me if I am wrong, of course.

    Look, the government actually owns GM - Government Motors. .

    Uhhh...what? I think you mean General Motors. And no, they are not owned by the US government.

    On the other hand, if anyone wants to point me to how to move the minimize/maximize/close buttons to the top right hand side of windows I'd appreciate it

    This is quite simple to do, but it does require some text editing. Here is a simple step-by-step guide -Quartinae

  5. Re:Sounds familiar. on Mom Arrested After Son Makes Dry Ice "Bombs" · · Score: 1

    That's not crazy at all. What would be the range of a 6ft rocket?

    Depending on apogee, weight, impulse, deployment altitude, et cetera, it would entirely depend. I have seen a six-foot long rocket land 20 feet from the launchpad with an apogee of 200-300 feet, because it had a very small motor.

    What kind of damage can it do with fuel still in it?

    Well, if properly configured with a parachute and other recovery systems, very little. You would need some kind of automatic electronic recovery system (a PerfectFlite miniAlt/WD would suffice) for deployment.

    In today's age, if I started messing with liquid fuels, or built rockets over 6 feet tall, I would likely get harassed by local law enforcement (or more likely my neighbors would call for them), assuming I could even get the proper permits to be allowed to build the thing... permits to build something with my own two hands and then test it out on my friend's private property (a farm)? CRAZY, and wrong.

    While that may draw some odd looks, there is a regulated process by which you can build that kind of thing. Building a six-foot tall rocket is not illegal (I have done it many a time, the largest I have built was a two-stage 11 foot sounding rocket, staging from a K1100T (about 256 times more powerful than a C) to a J1299L (about 128 times more powerful than a C)), and no permits of any kind are required to build it. You do need a certification (or to know someone with a certification) to buy larger propellants, which basically help you to be less of a hazard to others (because presumably if you have a Level 1 or 2 or 3 certification, you know somewhat what you are doing). You do know about the NAR, right?

    In short, rocketry is not illegal, but you do need to know what you are doing so that you don't kill or injure people people.

    Yes, there will be the earths gravity, but the temp of space would freeze it?

  8. Re:dumb question... on Deformable Liquid Mirrors For Adaptive Optics · · Score: 2, Insightful

    That is how they make glass mirrors. I believe the purpose of making liquid mirrors is not only to get a good reflective surface, but to also use Adaptive Optics (nearly infinite possibilities for reflective surfaces, so it would be really easy to correct for atmospheric anomalies). So, a frozen mirror (e.g. a glass mirror) would not work nearly as well as a liquid mirror for this.
