Comment Refraction (Score 1) 156

If what they recently proposed about the expansion of the universe is true (that space does not expand evenly everywhere in the universe, because it primarily expands in the presence of galaxies), then perhaps it actually compresses between galaxies, and gravity waves are refracted as they pass through.

Well you can't transmit the keys in their entirety to anyone anywhere, even if they're Apple- they have to be exploded out into thousands of pieces so that the pieces are useless until they are deliberately re-assembled by the masses. If all it takes is a single authorization, it is completely vulnerable; if it takes 100,000 authorizations, it is very much harder to compromise.

Imagine that device encryption keys were disintegrated across a peer-to-peer network such that a high number of users could unanimously authorize the unlocking of a single device. The idea is that it would be possible to unlock a protected phone, but it would require a mass consensus.

Comment REGULAR EXPRESSIONS (Score 1) 140

If there is one discipline to serve as a common root for the fundamentally different learning experiences of "computer science" and "software engineering" in the sense that is meant in the posts above, regular expressions. Regular expression syntax is absolutely not object-oriented and does not share any resemblance to natural human language, which makes the experience more like dealing with individual bits and numbers as in computer science, but still abstract and relatively informal. Regex may be the most widely applicable scripting skill to have. A finely crafted regex exercise could segway nicely into a computer science exercise working with datagrams.
