发帖数: 287 | 1 thank you! I think you are right. At first, I allocated money to five
equities options to maximize the growth, but seems like the price per share
is increasing, the stock and bonds market are not good? I am losing

代都适用？
2。谁说的每个帐号都要达到一样的allocation了？不同资产，不同帐号的tax
efficiency 是不一样的。
3。aggregate 一下总的百分比，然后rebalance 一下能有多难？每个季度或是每年弄
一次，excel里顶多10分钟的事。你要是google sheet里弄一个就更是一劳永逸了。
你要喜欢花钱，当然也可以找收费的advisor或是robo-advisor。别找太creative的，

I understand that a1 will be in stack, a1's j, k will be in stack too; s wil

2， a[5]到底在内存里面占几个字节？是5个吗？但是最后一个已经给了 '\0', 对吗？
3, a[5]是在stack中还是在heap中啊？如果用new 给b分配地址的话是在heap中，对吧？
#include
using namespace std;
int main()
{
char * b;
char a[5] = "1234";
strcpy(b, a);
cout << a <
cout << b << endl;
cout << "size of b " << sizeof(b)<
cout << "size of a " << sizeof(a)<

发帖数: 1453 | 30 It's tricky,depends on the how c runtime is linked. If I remember correctly,
each dll with statically linked has its own heap. Otherwise they share when
the runtime version is the same. Exe and dll have different heap. It's
common issue to allocate in one heap while delete in another module which
causes memory corruption.

发帖数: 39 | 32 Hi,
I am trying to track the memory usage, especially the page faults during
allocation. I found there is a getrusage() method, which tracks page faults
and page reclaims. My questions are as follows:
1. what does "page reclaims" mean? how to interpret it? Does that mean (a) if
a page Pi was used for Ni times without page faults, then ru_minflt = \sum {
Pi * Ni} ?

发帖数: 61 | 39 I'm doing some research these days on asset allocation. The common framework
seems to be starting with a set of scenarios on macro variables such as GDP

forecasted yields, premium, etc. then serve as the inputs for an optimizer
that will spit out the presumably optimal weights for each asset class.

Problem with MV is it is static, one period, results unstable and counter-

fat-tail in asset & liability return. JPMAM has a model does exactly that.
