最近收到这个协会在我们学校chapter发的加入邀请,要交70刀会费。我从来没听说过
这个组织。google了一下,wiki上的说法也有好有坏。有人说这个组织就是个scam. 想
问问大家是否知道更多关于这个组织的消息,是否有加入的必要?加入了真的对以后找
工作有好处么?

Just finished reading Nadia's comments on UK Open at DanceBeat. Actually, i
browsed the beginning part the other day, but did not notice the 'see next
page' stuff, so i did not even know she commented till the end of the comp,
haha...
Anyway, it is always enjoyable to read comments on couples' strength and
weakness, esp. the top ones. I wish i watched UK Open, so i could compare
notes. Still, i have some reflection --
1) Evgenij Voznyuk & Oksana Nikiforova: sounds like they are promising

A *p = new A[10](5);
编译不过吗?假设A 有合适的constructor.
A *p = new A[10]();可以编过,
难道 A 没有default ctor 就不能 动态分配数组?
(当然, 用allocator 和 operator , placement new 可以, 但是这也太底层了)
*************
答案:
动态分配的数组只能调用其default ctor,鉴定完毕! (有一本书上也是这样写的。)
I wrote some codes (no implementation is given) proving this conclusion as follows:

Google 就是个广告公司,软件和服务可以免费,甚至可以倒贴钱给你,但
广告过滤这种自短财路的事情是绝对不可能干的。
现在唯一能期望的就是尽快放出 Google Chrome 的源代码, 然后由第三方好事者
开发广告过滤插件。不过 Google 也有耍赖的办法 - 就像 Google Android 一样,
开放源代码项目宣布快一年了, binary sdk 放出了好几批,可就是打着 beta 的
幌子不公开源代码. Google Chrome 要像 gmail 那样 beta 四五年,借着测试
版的幌子像 Google Android 那样始终不公开源代码就无耻了。

天文学家发现了迄今为止最小的黑洞,同时,他们首次使用的新技术将帮助研究人员提
炼关于这些巨大天体如何形成的认识。
在恒星的生命周期中,质量是关键的一环。红矮星――其质量只相当于太阳的一小
部分――似乎不会毁灭。但特大恒星在爆发成为超新星之前却只有几百万年的寿命,它
们留下的密度惊人的内核最终会聚合成黑洞。在上述两类天体之间是一些“中量级选手
”,其中包括一种超新星残余――中子星,这种天体将与太阳相仿的质量装进一个小行
星般大小的外壳中。天体物理学家一直寻思中子星是在哪里终结而黑洞又是在哪里开始
的。理论模型预测,太阳质量的1.7倍到2.7倍是发生这一切的关键阈值。
由于无法直接观测这些天体,特别是难以找到那些小型的天体,天文学家不得不转
而测量它们对附近的恒星或周围的物质施加的引力或能量影响。然而这种方法的效果并
不十分理想。之前发现的最小黑洞的质量相当于太阳的6.3倍,比理论上的阈值大了许
多。
如今,两位美国宇航局(NASA)戈达德空间飞行中心的天体物理学家,利用一种新
技术找到了迄今为止最小的黑洞。它绝对是一个“小家伙”,其质量仅是太阳的3.8倍
,并且围绕一对双星伙伴运转,后者

google基本只做文字广告,我觉得搞个过滤图片广告的东西对他
不难。

I feel Nadia's comments on Oksana right on the spot, "sharp and clean."

She is very dynamic. I enjoyed their OSB show number "si no si."

I know the clip you are talking about. The dress is hideous for sure.
The dancing? I'm not a fan either.

Find it very hard to like them too. But I really want to watch the video.
She had a new hair style.

Totally agree with Nadia's comments. Sergei is semi god, Melia is too facial.
Yeah!

oops...i did notice that, which is very encouraging.

"Ke Qiang Shao & Na Yang (China)
have improved in that they refrained from overd
oingMalki-UK.jpg much of their dancing as
I have seen them do before. "
"Sonny Jin Zhang & Cher Wen Qing Luo (China)
had a strong Paso with very clearly
defined shapes. I enjoyed watching them as
the man had an especially nice delivery of
his dance movements. "

i am not very familiar with standard couples, so not much to reflect.
But there is something: i read some posts saying, both couple (Arunas &
Katusha, Jonathan & Hazel) are exciting to watch, but somehow the former
couple looks sharper or flows with more energy in the final than the latter.
I think this could be the reason:
"For couples who have not attained a top 24 place the year before there are
no exemptions. That makes it very hard for finalists who are competing from
11 am to 11 pm, thus

Following the lead of a self-claimed 'lazy' young lady isn't easy yah,
hohoho
Here you go:
"Into second place came the current World Champions, Maurizio Vescovo &
Melinda Torkgyorgy (Hungry) who are a charming couple with charisma plus.
They must have gone into this event feeling super confident as they have won
all major titles this past year. Maybe this was the problem! (A lesson
for all young and up and coming couples, never believe you have it in the
bag unless you are holding the trophy!
