发帖数: 626 | 8 The momentum to reclaim glory for USTC continues in
2007. First quarter is usually slow season for charity
donations, but the first month of 2007 became the best
ever January in AF history (toal $13920, comparing
with $6963 the 2nd best January back in Y2000).
USTCAF greatly appreciates following alumni, friends
and corporations for their generous contribution during
January of 2007 to our efforts in helping USTC and
its people.

That's an interesting question. I never thought finalize could
be used this way (or at least not for any practical reasons).
The javadoc of finalize does sound vague or even conflicting.
My guess is if an object is made available in its finalize, next time
it becomes unreachable, the VM won't call finalize and will reclaim
it directly.
I really can't think of any practical stuation where you want to
wait until finalize to "revive" an object. |

发帖数: 123 | 18
unreachable,
JVM only call finalize() once! If inside the code, this object is referred by
others, then it will never be reclaimed, so will cause memeory leak. So it
should be careful if you want to override this method(). |

发帖数: 1662 | 19 gc
public static void gc()Runs the garbage collector.
Calling the gc method suggests that the Java Virtual Machine expend
effort toward recycling unused objects in order to make the memory
they currently occupy available for quick reuse. When control returns
from the method call, the Java Virtual Machine has made a best effort to
reclaim space from all discarded objects.
The call System.gc() is effectively equivalent to the call:
Runtime.getRuntime().gc()

发帖数: 2421 | 20 well, theoratically, if JVM got killed, all memory claimed by JVM should be
reclaimed by OS, right? It is just a matter how can you be sure the JVM exit
gracefully. Correct me if I were wrong, to my understanding, once outofmem
exception occured, it would be quite unlikely to have JVM exit gracefully by
simply calling system.exit(), best way to do it is kill-9 |

发帖数: 21367 | 21 多谢各位大侠指点，先预祝新春佳节快乐 :)
我不是CS专业的，也没有学过operating system这门课，一直对
一个事情比较好奇，就是system calls是怎么实现的。
（linux kernel相关的书家里有，没有带过来，看也有点看不懂//blush）
系统已经在跑了，我写一个应用程序，包含一些头文件就能
调用系统提供的接口。那我的程序是怎么和系统内核交互的呢？
我的编译器怎么能告诉我的程序，运行到调用的时候跑去哪儿、用
什么方式取得系统资源呢？
比如说我写一个socket程序，调用了系统的socketcall()，
用blocked receive方法，系统是怎么把驱动那边收到的信息
送给我的程序的呢？通知可以是signaling，那怎么给我的程序
取走呢？如何保证万一我没取走，也能知道且及时reclaim memory？
另一个问题是，如果在用户态写一个程序，有办法设计一个接口，
使得其他程序也能调用并使用其资源么？假设其他程序不知道这个提供
接口程序的设计细节。
问题比较低级，还请多多指教，谢谢啊。 |

IMHO, you still need to read a good os (not kernel) book to understand the
concept of scheduling, context switch between kernel mode/user mode, IPC, .

发帖数: 7142 | 23 Look at the "Cached:" in /proc/meminfo.
Linux will try to cache memory whenever possible.
Memory at free is memory at waste.
As long as the kernel can reclaim those memory (by
dropping the cache). Kernel is not running out of
memory.
The free memory in kernel is memory that is currently
not used at all, in other words, wasted. The kernel
will try to cache stuff and keep the free memory low. |

发帖数: 34805 | 24 In java, you are still recommended to manually close an IOStream.
In certain case, you want to do it in a finally block,
that prevents some problem you may see in C++ coz the block is
guarranteed to be executed. It's also notable that since GC will reclaim an
non-referenced instance automatically, this is often not an issue even if
you didn't do that. |

发帖数: 1005 | 28 yes, we made the same conclusion after we evaluated OSGI.
On other drawback is that there's no guarantee the memory can be reclaimed a

main() is a function, program entry point.
If malloc memory in main, and do not free at the code,
the memory is freed after the program exits,the process
or thread is finished. The OS reclaims the resources.
But if this function is NOT main
and the function is called many times, it leaks memory.
You need to learn to program safely, defensively.
In a typical software, there is so many functions.
Each function can have multiple possible exit point.
