来自主题: MusicPlayer版 - How to determine the appropriate scale III
The easiest way to determine the correct scale or mode is to
find the scale or scales which contain that chord. For example,
if you want to solo over a Dm7 chord, you will notice that the
Dm7 appears in several different scales. It is in the Dorian
Mode in the C Major scale, the Phrygian in the Bb Major Scale,
the Aeolian in the F Major scale, the Dorian #4 in the A Harmonic
Minor and Dorian b2 in the C Jazz Melodic Minor. Any of these
scales will work over Dm7.(看到这的时候我很兴奋,呵呵). It all

How Body Fat Scales Work And Why It's Important
Body fat scales use a technique called Bioelectrical Impedance Analysis... o

A small and completely harmless electrical current is passed through your bo

Hot to Determine the Appropriate Scale or Mode
Determining the correct scale or mode to use requires a basic
understanding of the relationship between chords and scales.
Each note of a scale(or mode) generates a chord. These chords,
which form the basis of our harmonic system, are constructed by
combining the first, third and fifth notes of the scale or mode.
This is called three-part harmony. Certain musical styl

scale out难度
google最简单,google本身有技术,但是重点不在scale out本身
搜索引擎的scale out,yahoo已经实现过了,google的强项在于效率上的提升
facebook等social meadia略难
netflix等streaming比较难
payment gateway这种也比较难,都是transaction
但是transaction的scale out的难度跟streaming难度比
我觉得差不了多少,我在payment gateway公司干过
里面对于netflix非常推崇,文档经常说netflix怎么搞
所以我们也应该怎么搞

来自主题: Statistics版 - 关于SVM 数据scale的问题
我看别人的paper或是别的说明,都建议scale输入svm的数据到0-1。 但是我不清楚怎
样scale,以及这些方法对svm结果的影响。
假设: 一个人的年龄是输入数据,我找到数据中最大的年龄max和最小年龄min,然后,
new age= (old age-min)/(max-min),最后到[0,1]之间了。
但是,这样scale似乎是有问题的,因为60 虽然是20 的三倍,但是对结果的影响显然
不是3倍的关系。 假如我用另一个方法:我按照一定的规则,把年龄分段,假如5段的
话,这样就用5个取值 0或1的variable表示了这个连续变量年龄,这样会不会更好些?
类似的问题很多,比如我知道一个排名,从第一名到100名,显然第一名的影响不是第
100名的100倍,也许是10000倍。
有没有专门介绍常用scale方法的资料。
非常感谢。

【洒家学爬泳】速度不能scale,转身还是耐力?
对练过转身技术的人来说,转身是会提高还是会降低速度?
大家一般游一个直道50米还是两个25米夹一个转身蹬壁更快?
我现在25米在27秒左右,8-9 stroke cycle/length;50米1:01左右,9-10 stroke
cycle/length;100米常常是2:15左右,10-11 stroke cycle/length(游100米garmin
swim显示的速度四个length还是比较平均的,在32-34秒左右,有时后面的length时间
还短点儿)。在不同的距离中感觉用力程度大致是一样的,都没有all out。
从转身来说,没怎么练过,算是open turn,蹬壁以后会觉得有点缺氧(尽管转身前已
经大吸一口气),缺氧后腿会有点酸。从耐力来说,划频随着长度增加而增加。也不知
道到底是转身还是耐力的原因,速度不能scale。

比较距离double情况下速度的scaling
25-->50,1.13
50-->100,1.11
都偏大。
再看tempo的变化
25:3.18
50:3.21
100:3.21
假设你掉头蹬壁滑行的距离和你出发的时候差不多。你在100以下是典型的恒频选手。
scaling factor略大(1.13,1.11)的原因,估计主要是划水力量下降略快或者身体姿
态保持变差造成的;改善蹬壁也会减小一点,但贡献有限;因为蹬壁之后觉得憋气,可
能应该及早上浮。

来自主题: gardening版 - 求教如何消灭Scale
药物的话可以用除虫菊溶液盆,直接杀死。洗洁精溶液对 scales效果一般。
听说有一种 wasp是 scales的天敌,具体哪种我也不知道,要查一下。
杀虫后要控制根部蚂蚁的数量,以免复发。
