1979: Vietnam invaded by China

When first noticed the title was a little shocking although the fact it is. Then the keywords anti-Chinese and pro-Soviet, plus “the passive voice” of the title retain the neutrality.

薛定谔方程

-\frac{\hbar^2}{2m}\nabla^2\Psi+V(r)\Psi=-i\hbar\frac{\partial\Psi}{\partial\,t}

四种类型的积分方程

Volterra 1st:

\int_a^xK(x,t)u(t)\,\mathrm{d}t=\upsilon(x)

Fredholm 1st:

\int_a^bK(x,t)u(t)\,\mathrm{d}t=\upsilon(x)

Volterra 2nd:

u(x)=\upsilon(x)+\int_a^xK(x,t)u(t)\,\mathrm{d}t

Fredholm 2nd:

u(x)=\upsilon(x)+\int_a^bK(x,t)u(t)\,\mathrm{d}t

If you wish to get a comprehensive idea on this Q&A, just follow here.

Q: What do you think about the regular hype about the release of a new version of Microsoft Windows or Apple OS X?

A: An o/s should never have been something that people (in general) really care about: it should be completely invisible and nobody should give a flying f*** about it except the technical people.

……

To Microsoft and Apple the o/s is important as a way to control the whole environment, from a marketing and money-making standpoint, to force people to upgrade their applications, and your hardware.

Q. Do you have a favorite between Leopard and Vista?

A. I don’t think they’re equally flawed. I think Leopard is a much better system. On the other hand, (I’ve found) OS X in some ways is actually worse than Windows to program for. Their file system is complete and utter crap, which is scary. I think OS X is nicer than Windows in many ways, but neither can hold a candle to my own (Linux). It’s a race to second place!

Q. Are Asian countries embracing open source as developers?

……

In summary, language barrier & cultural barrier .

Well, apple fans never want to hear that from Linus, maybe they don’t care^-^, let’s hope ZFS will happen in Leopard someday…….
