所有子节点都置0？感觉不需要，下面的python实现中仅把该节点下所有左孩子置0：

if 2*x+1<=n and A[2*x+1]==0:
A[2*x+1]=1
setbit_down(A,2*x+1,n)

A[2*x+2]=1

def set_bit(A, pos, length):
if not A or pos<0 or length<=0:

Under preemptive scheduling, the highest priority task executes until it enters the waiting or dead states or a higher priority task comes into existence. Under time
slicing, a task executes for a predefined slice of time and then reenters the pool of ready tasks. The scheduler then determines which task should execute next, based
on priority and
other factors.

发帖数: 112 | 7 第1个问题：
如果是个简单的controller
controller: doDevice(deviceID, commands)
这里doDevice不是一个固定的名称，而是针对不同设备定义的，比如doWashMachine()
，然后具体怎么调用设备命令就在里面具体实现。这样的好处是结构简单，很容易实现
，不利之处是随着设备增多和需求变化，controller会变得非常难以维护。
如果是要求比较复杂的controller：
controller: runTasks(), runTask()
Task: {multi-rooms, multi-devices} run(), pause(), stop(), restart()
Task类可以是个抽象类或者接口，供下层具体实现逻辑，得到device的实例然后调用相
应的方法。
第2个问题：
我用java，c++不是很懂。但是我觉得这里controller得用多线程的思路。
简单的做法是每个task开一个线程，然后自己去查询时间是否到了。好处是实现起来简
单，坏处是随着task增多，对系统资源的占用也比较大。

If some tasks run much quicker than some other tasks (and if there is a way
to classify tasks beforehand, before they are dispatched to queues), then it
is better to have more than one queue, with at least one queue dedicated to
the known fastest tasks and one dedicated to the known slowest tasks.
Queueing theory also explains why supermarkets have "express checkout queues

发帖数: 8565 | 20 知道什么原因了：
因为我在KDE上task-bar也是auto-hide，在windows上task-bar也是auto-hide。
Remmina全屏的时候，鼠标走到桌面最下方首先唤起的是KDE的task-bar。
而这个task-bar有被Remmina全屏遮住在下面，所以什么都看不到。
我试验把KDE的task-bar改成always visible，这样就可以唤起windows的taskbar了。
这里的原因是：Remmina不截获KDE的鼠标或键盘事件。
比如这个鼠标唤起task-bar的事件，既是KDE的事件，也是windows的事件，
Remmina不截获它，把它传给KDE了，结果windows的task-bar就不能唤起。
如果KDE的task-bar设为always visible，那么这个事件就不是KDE事件了，
这个事件就被Remmina传给windows，唤起了windows的taskbar.
Ctrl+Alt+Arrow在Remmina时好用也是一个道理。
另外Alt+Tab，这个组合既是KDE也是windows切换程序的事件，

发帖数: 417 | 27 说个在这个板上关于上升星座的不一样的看法。。同时也谈谈太阳和月亮。
我觉得区别一个上升、太阳和月亮的一个重要因素是在面对压力和放松时候的表现。
从这个角度看我觉得上升星座不是面具，而是灵魂和潜意识，在自己最轻松自在，没有
压力的时候的，毫不掩饰的真实的自己，一个大方向上的性格。无论有无压力，这个潜
意识一直都在那里。
想想一个人的时候，和最令自己放松的人在一起的时候，或者想象一下，没有任何压力
时自己是什么样的？平时喜欢表达情感的人还表达吗？喜欢服务的人还服务吗？要求高
的会不会就无所谓了？
在做一个task的时候，上升是一个大方向的舵，比如上升天秤，大的picture是这个
task要做得平衡有品位。上升水瓶，大picture是要独特并且innovative。如果不这
样，就会不喜欢这个task的 "idea"。
太阳星座是面具，在他人面前和压力面前表现出来的特质，有时也是想拥有的和完善的

Bookmark是我对什么东西特有兴趣，下次希望还能找到。我觉得没有和别人分享的理由。
如果要，理由是或许你看到某人的程序写的不对，想让大家都看看。这时bookmark的内容
会是important: .. 或者 fixme: ...。但这样的事情在团队开发里都是Task, 级别不同
的Task。
你的Task会是什么？Task内容是和源码紧密相关, 需要团队所有人能在第一时间看到的。
源码可以是广义的包括java, 配置文件，测试和例子等。和源码紧密相关的评论为什么要
和源码分开呢？你难道不希望一个人看到一段程序时，第一时间了解到还有什么没完成吗
？
Task是Javadoc里很重要的一部分，也是开发协作的重要部分。你会发现所有的开发工具

That Facebook is hugely distracting is hardly stop-the-presses kind of news,
but parents might be dismayed to learn that the social-media site can
hobble learning and make kids less healthy and more depressed.
Research has found that students in middle school, high school and college
who checked Facebook at least once during a 15-minute study period got lower
grades. Other studies have discovered that teens who use Facebook tend to
have more narcissistic ... 阅读全帖 |

By THOMAS M. BURTON and BETSY MCKAY
A government health panel on Monday for the first time recommended testing
for the human immunodeficiency virus for all Americans aged 15 to 65, in an
effort to slow its spread.
An estimated 200,000 people in the U.S. are infected with the virus that can
cause AIDS and don't realize it. The U.S. Preventive Services Task Force
said the new draft recommendation is aimed at preventing those people from
infecting others or develo... 阅读全帖 |

发帖数: 117 | 42 不是很明白这里第一题和第二题。
第一轮： offset 和 len 代表的含义是？ （binary tree是以array形式存储？这能解
释offset，但len呢？array的总长度？似乎不太make sense）
第二轮： 这里的考点是在call这两个方法时需要对队列加锁来达到正确性吗？
我基本思路是需要设置一个boolean变量 a 来确认是否已经trigger了。
trigger(){
aquire(mutex_a);
a = true;
dispatch all tasks in the queue;
head = null;
tail = null;
release(mutex_a);
}
addtask(){
aquire(mutex_a);
if(a)
dispatch the task;
else{
if(head == null){
head = task;
tail = task;
} else{
tail.next = task;
tail = task;
}

发帖数: 755 | 44 There are at most eight servers in a data center. Each server has got a
capacity/memory limit. There can be at most 8 tasks that need to be
scheduled on those servers. Each task requires certain capacity/memory to
run, and each server can handle multiple tasks as long as the capacity limit
is not hit. Write a program to see if all of the given tasks can be
scheduled or not on the servers?
Ex:
Servers capacity limits: 8, 16, 8, 32
Tasks capacity needs: 18, 4, 8, 4, 6, 6, 8, 8
For this example, th... 阅读全帖 |

发帖数: 3319 | 47 1. Introduction
My interest in studying creativity was inspired by the frustrations that I
felt as a student, then as a professor. I wanted to know how I could
encourage creativity in myself, my students, and my colleagues.
Politicians, industrial managers, academic administrators, and other leaders
often say that innovation is critical to the future of civilization, our
country, their company, etc. But in practice, these same people often act as
if innovation is an evil that must be suppressed,... 阅读全帖 |

背景不用交代太多，知道我的人，基本都知道我从事哪一行业，再多说了就被人肉了，
不过真被人肉了也不是很怕了，已经到了TMD这一步。。。。
背景是这样的，公司要换更新产品的硬件，所以软件也要相应调整，组了个team由一个
PM和一个部门经理管理，这个部门经理是去年到公司的，VP多年的朋友/同事，来了肯
定就直接是Senior 工程师，年底给升了另外两个部门的经理（这人确实很全面，估计
是奔着director去的，但是他现在不是我的直接领导，只是team leader），我在三周
前被安排了一个task，而且也确定了3个礼拜的action items （这个task，这个
manager 本来预估是20小时给软件，结果被我们软件的经理和lead争取到了120小时，
他一直耿耿于怀，念念不忘据说），但是后来的meeti... 阅读全帖 |
