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.

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.

+ - Windows 8 Leaked, Microsoft Looks To Apple->

Submitted by j0hnyquest
j0hnyquest (1571815) writes ""Over the weekend, the Italian Windows site Windowsettea got ahold of some super secret squirrel Microsoft presentations apparently laying around on the internet somewhere." The leaked presentation contains a large number of seemingly legitimate slides from a Windows planning committee. Of special note is a slide entitled "How Apple Does It: A Virtuous Cycle" where they make the groundbreaking assertion that product satisfaction leads to brand loyalty. The "Mac Envy," detailed here: doesn't stop at just product loyalty — Microsoft even has plans to introduce their very own "App Store.""

Spitzer Telescope Witnesses Star Being Born 34

from the get-off-my-cosmic-lawn dept.
Arvisp tips news of a discovery by astronomers using the Spitzer Space Telescope and the Submillimeter Array in Hawaii of the youngest known star in a nearby star-forming region. From the Yale press release: "Astronomers think L1448-IRS2E is in between the prestellar phase, when a particularly dense region of a molecular cloud first begins to clump together, and the protostar phase, when gravity has pulled enough material together to form a dense, hot core out of the surrounding envelope. ... Most protostars are between one to 10 times as luminous as the Sun, with large dust envelopes that glow at infrared wavelengths. Because L1448-IRS2E is less than one tenth as luminous as the Sun, the team believes the object is too dim to be considered a true protostar. Yet they also discovered that the object is ejecting streams of high-velocity gas from its center, confirming that some sort of preliminary mass has already formed and the object has developed beyond the prestellar phase. This kind of outflow is seen in protostars (as a result of the magnetic field surrounding the forming star), but has not been seen at such an early stage until now."

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.

The Mass Production of Living Tissue 157

Posted by Soulskill
from the syfy-has-already-bought-movie-rights dept.
An anonymous reader sends in this moderately disturbing quote from Gizmodo: "I'm touching a wet slab of protein, what feels like a paper-thin slice of bologna. It's supple, slimy, but unlike meat, if you were to slice it down the center today, tomorrow the wound would heal. It's factory-grown living tissue. The company behind the living, petri-dish-grown substance known as Apligraf hates my new name for it: meat band-aid. 'It's living,' Dr. Damien Bates, Chief Medical Officer at Organogenesis, corrects me. 'Meat isn't living.' But no one argues with me that this substance is really just a band-aid. A living, $1500 band-aid, I should say. Apligraf is a matrix of cow collagen, human fibroblasts and keratinocyte stem cells (from discarded circumcisions), that, when applied to chronic wounds (particularly nasty problems like diabetic sores), can seed healing and regeneration. But Organogenesis is not interested in creating boutique organs for proof of concept scientific advancement. They're a business in the business of mass tissue manufacturing — and the first of its kind."
