Submission + - The Intel 4004 Microprocessor Chip Turns 45 1

mcpublic writes: Today marks the 45th anniversary of the 4004, Intel’s first microprocessor chip, announced to the world in the November 15, 1971 issue of Electronic News . It seems that everyone (except Intel) loves to argue whether it was truly the “first microprocessor.” Ken Sherriff's recent article in IEEE Spectrum tells the more complicated story. But what’s indisputable is that the 4004 was the computer chip that started Intel’s pivot from a tiny semiconductor memory company to the personal computing giant we know today. Federico Faggin, an Italian immigrant who invented the self-aligned, silicon gate MOS transistor and buried contacts technology, joined Intel in 1970. He needed both his inventions to squeeze the 4004's roughly 2,300 transistors into a single 3x4mm silicon die. He later went on to design the Intel 8080 and the Zilog Z80 with Masatoshi Shima, a Japanese engineer with a “steel trap mind,” the once-unsung hero of the 4004 team.

So the FBI wants people to cooperate with them, to use weak encryption so they can unlock data when they need to. OK. Who is going to do that? Let's say law-abiding people will cooperate. What compels criminals to cooperate? What compels non-Americans to cooperate? What prevents people from use their own additional encryption, like putting a 2nd lock on your door? What prevents people from obfuscating their data? Here's the key, see, it's a Rick Astley video.

Yes, the Harvey's Casino bomb story is interesting. But saying "here's what a real bomb looks like" is like showing an image of a bowl of noodles and saying "here's what real food looks like." It doesn't help you identify whether or not another thing is food (or a bomb).

what if you're half a mile away from the south pole? i think that works. what about 3/4 of a mile? 7/8? as long as the one mile south gets you to a point on a circle around the south pole whose circumference is 1/2^n of a mile, I think you'd be good. Would he really ask about miles rather than km?

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
