Facebook | Quantitative finance tool for everybody
Facebook | Quantitative finance tool for everybody: "online soon
the ultimative finance tool for everybody
Systematic equity trading
Issue of the traditional stock analysis
- With the flood of financial information it has become for the investor impossible to accurately filter and interpret all performance-relevant information.
- Analysis are mostly realized ad-hoc and therefore neglect ex-post performance-relevant information
- Decision making processes are often based by emotions. This affects adversely the performance.
The majority of the financial industry applies the traditional stock analysis. Because clients have not demanded higher added value so far, hardly any financial institution goes unconventional and progressive ways. But, this would be exactly necessary for delivering clients a high added value as possible.
The solution for investors
The prerequisite for archieving higher added value are disciplined processed of decision making,which analyse systematcally over the entire time-axis all performance-relevant factors of the financial markets and provide unambiguous trading instructions. This methodical approach avoids adverse emotional patterns and generates above average returns even in turbulent market conditions.
Furthermore, it enables a consistent and broad coverage of financial markets through which opportunities can be used on a global basis in an effective and efficient way.
All this is accomplished by combining comprehensive financial knowledge with most modern IT, which based on objective data and information delivers systematic evaluations.

Test Ez Publish 4.0.2
2009/2/13,In my ubutun server in VMware, I test install Ez publish 4.0.2 CMS system.
Download Ez Publish from http://ez.no, copy file to share directory, so my vmware ubutun can see the file.
config mysql database
mysql -u root -pmypassword //replace real passwd to mypassword, no space after'-p'.
Create new database:
CREATE DATABASE ezpublish CHARACTER SET utf8;
GRANT ALL ON ezpublish.* TO ezpublish@localhost IDENTIFIED BY 'ezpublishsqlpassword';
FLUSH PRIVILEGES;
Then I uncompress eZ Publish:
cd ~/share
tar zxvf ezpublish-4.0.0-gpl.tar.gz -C /var/www
This creates the directory ezpublish-4.0.0 in /var/www which I rename to ezpublish:
mv /var/www/ezpublish-4.0.0 /var/www/ezpublish
Then we should change 'Php.ini' , change 'mem_limits=16M' to 'mem_limits=64M', because Ez publish need 64M memory in PHP:
cd /etc/php5/apache2/
sudo vi php.ini
Then we need restart apache server:
/etc/init.d/apache2 restart
Next we need to install "imageMagick":
sudo apt-get install imagemagick
Next we set proper access permision:
cd /var/www/
sudo chmode -R a+rwx ezpublish
Now, we can visit "http://192.xxx.xxx.xxx/ezpublish/index.php" to continue install ezpublish. It really work.

Install Samba in Ubuntu
In my ubuntun server in VMWare, I test samba which I use to tranfer file between host XP system with VMware ubuntun server.
First, backup the original config file: /etc/samba/smb.conf like this:
> cd /etc/samba
> sudo cp smb.conf smb.conf.old
> sudo cp smb.conf smb.conf.master
> sudo vi smb.conf.master
Only Add a new share directory [share], don't change other contents.
Create a new subdirectory in your home directory, my home directory is /home/wjh,
I create a subdirectory 'share' under '/home/wjh', and change the access permit:
>cd /home/wjh
>mkdir share
>chmod 666
Edit '/etc/samba/smb.conf.master, add content below:
[share]
read only = no
locking = no
path = /home/wjh/share
guest ok = yes
browseable = yes
run ' testparm -s smb.conf.master >smb.conf '
restart samba server: /etc/init.d/samba restart
In the XP, you can search host, in address bar "//192.xxx.xxx.xxx/share", then you can visist sambar share directory

[转载]VIM的剪贴板小技巧收藏
VIM是Linux下功能非常强大的一款字符处理软件，功能如何，在这里就不再做过多的评述了。很多朋友在使用VIM的时候，可能都会遇到一个非常简单，但是又很奇怪的问题，就是关于VIM的剪切板。
我们先做这样一个小小的尝试，请打开浏览器，从网页上随便复制一段文字，然后打开VIM，用“p”粘贴一下，你会发现，什么都没有站贴过来，呵呵……原因是这样的，不同于Windows，VIM具有多个剪贴板，并且和系统剪贴板是完全独立的，所以当你复制浏览器里的文字的时候，这段文字保存在了系统剪贴板，当你是用“p”来粘贴的时候，实际上，他读取的是VIM的剪切板。
那怎么方便的将系统剪贴板的内容复制过来呢？简单！用另外一个快捷方式“Shift+Insert”就可以了，如果你在使用Gvim的话，直接用鼠标中键也可起到相同的作用。是不是很简单？
好了！现在您已经学习到了VIM剪贴板技巧的基础！OK！我们开始进阶！
我们前面说过，VIM具有多个剪切板，目的是为了用户在做较复杂的字符处理的时候，可以更方便的复制粘贴。请现在使用一下“:reg”命令（先按ESC 键，退出编辑模式，然后按:进入命令模式，然后输入reg回车），看到了？屏幕上的输出结果！是不是特别眼熟，对了！就是您之前复制过的所有内容！也许这时候您还发现，VIM的剪切板原来有这么多个，按照数字还有符号一个一个的区分开的，这里举一个编号的例子——"5，看到了吗？是以"开头的。还有！有没有看到编号为"+的剪切板？里面的内容是不是刚才你在浏览器里复制的那段文字啊？呵呵……没错了！系统剪切板的编号就是"+。
好了，这时候您已经知道了如何查看之前的所有剪贴板内容，我们现在就试着把某一个特定剪切板的内容复制进我们正在编辑的文件中。我们知道，vi的粘贴指令是 “p”，但是如果要粘贴一个特定的剪贴板，只是用p就不行了，那怎么办？简单！把剪贴板的编号带上不就可以了？现在先按ESC，退出编辑模式，然后一词按 "+p这三个字符（怎么按？不会吧！"和+怎么按？用Shift啊！），好了！你看看，之前在浏览器中复制的这段文本，是不是被粘贴进文档中了？
如何将系统剪切板里的内容复制进VIM当中，您已经清楚了。那如何将ViM中复制的字符粘贴到其他地方呢？很简单，我们只需要把要复制的文字，复制进" +剪切板不就可以了？（"+剪切板是系统剪切板，忘记了？）在VIM中，复制的指令是y（在非编辑模式下按y就可以了），那要将文本复制进指定的剪切板，和粘贴指定剪切板内容的方法一样，只需要加上剪切板的编号就可以了。举个例子，我们希望把VIM中的一段文本复制下来，然后粘贴到浏览器的地址栏中：第一步，现把需要复制的文字选中（非编辑模式下），然后在键盘上依次按"+y这三个字符，OK！已经复制下来了，现在用:reg命令看看，是不是在"+剪切板中了？
