前面2个客服也比较nice,
然后呢,
说到traceroute的时候,客服说这个time是incremental的,但是我说是each hop的,
后来跑来一个女的又说是incremental的,粗鲁了一下。呵呵。
我觉得吧,虽然是个简单问题,但是这个time是怎么算出来的呢?TTL只能算多少跳吧
,每一跳的时间怎么算呢?好奇啊。

use /capture /verify switch when you want to backup, and use /append /verify
switch when you do incremental backup.
For example, you installed OS and all drivers, use /captuer /verify to do
your first backup, and then you install Office, use /append /verify to do
incremental backup. The 2nd step append to the first backup file you created
. Later you can decide only restore to the first backup, or revert to the
1st+2nd backup.

simplest and cheapest is windows backup.
incremental backup is the most efficient. You only backup the files that
changed since the previous backup. But if anything happens to the base
backup, everything after it become useless.
Best solution: 1 whole disk image for the fresh installed disk. 1 whole
disk image for the last successful major change to your disk and you are
sure you don't need to go back further than that. Incremental/differential
backup for everything since that image. And t... 阅读全帖

我刚刚按一下的方法作了一边:
1. With acpi-support 0.109 (hardy) or 0.114 (intrepid) installed and laptop-
mode *not* enabled in either /etc/default/laptop-mode or /etc/default/acpi-
support, monitor the load cycle count of your hard drive by running 'sudo
smartctl -a /dev/sda|grep Load_Cycle_Count' over an interval of several
minutes, and observe that it is incrementing. (If it does not increment,
your hard drive's manufacturer defaults are sane and you are not affected by
this problem.)

The presence of increment operator changed the execution order. It is
compiler dependent, since standard c++ doesn't define the order explicitly.
Your k++ is evaluated to 0 first, and then it increments k to 1. Then ip[k]

Agreed.
If parallelism only occurs at the framework level, then the latency of
processing cannot be reduced, and the CPU will be under-utilized (if there
are not enough requests at the framework level).
Certain image processing operations are non-parallelizable - when considered
alone. Examples are image decoding and encoding. However, that doesn't mean
other image operations had to wait until these operations finish - other
image operations can use partial results, and can do so from a differe... 阅读全帖

系统主要特点:
- 多线程。(老魏没有给出具体多少个线程,假定100个吧。我的12 core intel xeon轻
轻松松100 thread)
- 无锁。
- 单机。
数据结构:
1. 全国1000条线 (X1, X2, X... , X1000), 每条20个区段 (S1, S2, S3... S20)。
2. 每条线的每个区段的票的总数计为:T[X1,S1], T[X1, S2]....... T[X1000, S20]
抢票程序(注意举得例子是联票)
1. 100个thread处理收到的请求
2. 每个请求包括三个参数(线路, 起始站,结束战). 比如(234次列车, 济南, 上
海)。 (注意, 234次列车是从沈阳出发,到上海的, 济南是第5个区的开始,上海最
后一个区段的结束)
3. 计算过程就是把234次列车从济南到上海的每个区段的票数做interlocked.

来自主题: Programming版 - 测试用例在此,看还有什么说的。
跟你说了decrement再increment不是原子操作,你真是连基础知识都没有。
假如现在就剩一张票a->b, 来了两个单子a->b->c 和 a->b.
DB transaction保证了无论以任何顺序执行,a->b得票都能卖出去。
decrement再increment得做法,当单子同时到得时候,就有可能产生这样得执行顺序。
decrementAndGet(a->b) = 0, decrementAndGet(a->b) = -1
decrementAndGet(b->c) = -1.
结果就是票子没卖出去。
卖票得原则大家都很清楚,不许错票重票,不许有票不出。这个case可能最终导致好好
的票子卖不掉,正确性都不能保证,还谈个屁性能。没有正确性的高性能没有意义。
那几个捧臭脚的好好反思吧,到底谁是半瓶醋。
至于魏公公,不能把这个测试用例驳倒,就永远做太监吧。

你觉得想想就累,没想对方向而已。现在大家都还没想对方向。
真想对方向了,一切就都显而易见了。我也还没想对方向。
机会在于,大部分人根本没有创造力。他们还会一根筋地往穷举法

穷尽,他们就会接着往下走。只要他们还在那条路上走,
我就还有优势。

电灯早已经存在,白炽灯也早已经存在,而且都在他“发明”之前就已经诞生。爱迪生靠对电灯的“卓越”的制造品质以及营销大赚了一笔,多么恶心卑鄙。
这些家喻户晓的名字还有故事,你一定不会陌生:爱迪生发明了电灯,贝尔发明了电话,惠特尼发明了轧棉机。
不过你可能不信,事实上这些并不是他们发明的。他们可不是雅典娜下凡,那些创想也非灵光一现,总之肯定不是他们的一人之力。 其实,没有一项发明创造是由某人单独完成——发明家和他们的“发明时刻”的神话。
“任何发明创造,即使是那些改变时代的、不同凡响的发明,都是由瞬间的灵感以及在此基础上不断地改进相结合而完成的。” 马克.A.莱姆利(Mark A. Lemley)在他那篇著名的文章《唯一的发明者之谜》中这样说过。莱姆利的这篇文章中主要讨论了发明专利的历史及存在的问题。 不过,其中他也记述了19世纪和20世纪最著名的发明家的故事——只不过重点很独特,主要阐述了这些发明家的发明并不是一人之力完成,有些发明甚至跟他们没有任何关系,张冠李戴了而已。 莱姆利对过去200年间的“协作创新”做了非常精彩的描写,下面几段故事就是对其描写的提炼。

Liu Xiaobo wins Nobel, reform loses
China has many unsung heroes pushing for democracy. Their task gets harder
when the west rewards high-profile dissidents
* Nick Young
Liu Xiaobo, the jailed Chinese pro-democracy activist who has just been
awarded a Nobel peace prize, is certainly a brave man, and his imprisonment
is deplorable. But it is hard to see what contribution he has made to peace,
in China or beyond, or how... 阅读全帖
