发帖数: 69 | 6 It is understood that auto_ptr should not be used with STL container.
For example, it is seriously wrong to call sort from header to
sort a vector>, if the implementation uses quick sort and a
pivot, a copy of some element, is used.
Unique_ptr has the same feature of taking ownership when copying as auto_ptr
. I know that unique_ptr's assignment operator uses rvalue reference, but
the same problem in the above example remains: the pivot takes ownership of
some element, ... 阅读全帖 |

init(s) was called by the order of dependency tree.
if in same folder level, called alphabetical order.
e.g. if two init functions have concurrent writings to same map, then god

BTW: you can avoid such thing happen by using sync.Mutex or concurrent map

发帖数: 79 | 11 I have a program with 2 threads running on Solaris using g++.
I noticed that I got core-dumped at one thread's:
new char[2];
gdb trace tell me it's inside malloc.
And I checked my program, it happend when one thread 1 send data
to another thread 2. In thread 1 it will delete some data, thread 2
will use new to create an instance.
After I comment the delete of thread 1, I got no core-dump at all.
So, I am very suspicious of g++'s new/delete is not thread safe.

I have some problems with removing the external usb hd using "Safely

Sometimes, a pop-up window says "Can not stop the drive because

Is there anyway to figure out which program/process is using the drive

于是小小研究一下，从统计学数据上来说，小车是比大车在事故中死亡率更高。我本来

于是看到这个

但是值得一提的是，pickup的事故死亡率，大和非常大的pickup几乎和small car一样
，small pickup的死亡率更是高过small car，而pickup基本上比不管大小的SUV死亡率
高一倍。
有网站的人讨论，这是因为司机最重要。开pickup的一般比较redneck，教育程度可能
较低，可能更aggressive。开小车的年轻人更多，比如大学生，高中生，刚工作的，因
为穷。这些人经验不足，年轻气盛，不少刚可以喝酒，酒后驾车也多。确实另外有数据
