linux 下面的mail只需要输入receiver的email，比如说[email protected]。

在server上有这样一个函数:
void getinput() {
int count;
char buf[12];
...
gets(buf);
...
}
gets()读入一段input到buf中。如果buf够大，可以放一段shellcode到stack上，实现
buffer overflow的攻击。问题是现在buf只有12 bytes,放不下一段shellcode,那么这

一个比较民科的想法，大家帮忙看看
假如A国家有100 A元 currency，B国有100 B元currency，
没有其他asset比如checking etc。A元和B元的汇率是1:1
如果一个A国人想到B国投资10元，是找B的央行用10 A元换10 B元么？
B的央行需要印出10 B元么？ 这时候B的economy里有110 元，B国通货膨胀了么？

I am not international economics, so I am just giving my intuition here.
First, that 10 A's currency is not circulating in country B. As a resulty,
it is not increasing the money supply directly and won't cause inflation.
Second, Country B's bank can loan that 10 A currency to country A's
investors.
Third, A's investor should exchange the currency with B's commercial bank,
not central bank.
If anyone in International fields can give some hints, that will be great.

有点大的说。
何况还没那么大必要~~
MacTeX-2012
MacTeX-2012 installs updated versions of the GUI applications that were
already in MacTeX-2011.
MacTeX has optional packages to install two font collections (Latin Modern
and TeX Gyre) in /Library/Fonts; these TeX fonts are already in TeX Live,
but installing them in /Library/Fonts makes them available to standard
Macintosh applications like Adobe Illustrator. By default, these fonts are
not installed.
MacTeX installs the latest version of Ghostscript, 9.05, and an updated "
Convert" from ImageMagick 6.7.6-9. These packages are self-contained; MacTeX
installs no libraries in /usr/local/lib.
In previous years, MacTeX was provided as a zip file. The install package
was rewritten this year using Apple's modern PackageMaker, so this year's
MacTeX-2012.pkg is a flat file which doesn't have to be zipped for a server
or unzipped after downloading. The package is signed so it can be installed
on Mountain Lion.
TeX Live 2012
MacTeX-2012 installs a completely unmodified copy of the full TeX Live 2012
distribution. This is exactly the same distribution that runs on OS X,
Windows, GNU/Linux, various BSD Unix systems, and other systems.
MacTeX-2012 contains two binary directories. The first, universal-darwin,
contains 32 bit binaries for both Intel and PowerPC processors; these run on
all Macs which have OS X 10.5 or later. The second, x86_64-darwin, contains
64 bit Intel binaries compiled on Snow Leopard; these programs run only on
Intel machines which are 64 bit capable and are running Snow Leopard, Lion,
or Mountain Lion. Our tests show that the 32 bit binaries run very fast on
64 bit machines, so most users won't notice the difference between these two
sets of binaries. Since the 32 bit binaries run fine on Leopard, we had the
luxury of compiling 64 bit binaries only for Snow Leopard, where we could
use Apple's modern libraries.
Two programs in x86_64-darwin are still 32 bit versions: xetex and xdv2pdf.
That is because the Mac versions of these programs use a deprecated font
library which Apple did not port to 64 bits.
