Do you support the inclusion of creationism alongside evolution in high school curricula? If so, how can you justify teaching a science class with creationism's Christian slant? Also, how can you justify the potential unequal representation of Christianity's story when compared to creation stories told by other major religions?
Let's get a unified vision, build a stable and streamlined foundation of a set UI, default apps, and packaging system. If this happened, Linux might actually be as useable and as easy to use as a commercial OS. Playing around and making your own distro should still be done and encouraged, but I can't see much progress without at least one solid default base from which others could spring off of, add ideas to, play around, and experiment with.
Just a slight correction: the solid rocket boosters (SRBs) dont use monomethyl hydrazine or dinitrogen tetroxide. They primarily use aluminum perchlorate.
In addition to the destruct switch, there are other flight plans for an intact abort in case of problems. These abort modes are: Return to Landing Site (after SRBs are jettisoned, shuttle returns to Kennedy Space Center); East Coast Abort Landing where the orbiter lands on a different runway somewhere up the East Coast of the US; Transoceanic Abort Landing where the orbiter lands somewhere in Europe or Africa; Abort to Orbit; and Abort Once Around.
The Solid Rocket Boosters can't be stopped once they are started, but they have their own navigation system (rate gyro assemblies, and inertial measurement units) that are considered as/more reliable as those on the orbiter due to the rigidity of the SRBs. So the reason this "self destruct" button exists is because there is no "off" button for the SRBs, but, as far as I know, it is only an issue if its quad-redundant navigation system fails and somehow its thrust gets stuck in an unsafe vector, and that is very unlikely.
With a real book, there's something magical about turning pages. Just like there is something magical about owning a record or CD, which is why music will never shift to digital formats. Oh wait...
