lizhao — Mon, 06 May 2013 06:16:44 +0000

At ubuntu command line, make sure
1. curl and git are installed
2. http_proxy and htts_proxy are set
3. use http url of the git repository to access it
3. ~/.gitconfig has ‘[http] sslverify = false’, if met ‘https://lizhao.ok%40gmail.com@git2.projectlocker.com/lizhao/DanceVee.git’

1. 打开kisbook.xlsm

2.把生字放进这个excel表

3.选中要生成的字

4.点’generate’键

5.如果你不满意生成的缺省字体，可以改新打开的word文档

对于外婆的要求，我要改成虚线字体，如图：

6.点’generate’键

7.打印（可以调整页面布局，让所有列打印在一页内）

Mondrian Config

lizhao — Mon, 22 Oct 2012 08:13:16 +0000

Notes: for Mondrian 3.4.1, the install.html is problematic, for mysql, here is a working config (mysql):

/WEB-INF/datasources.xml:
Provider=Mondrian;DataSource=MondrianFoodMart; Mondrian FoodMart Data Warehouse http://localhost:8080/mondrian/xmla Provider=mondrian;Jdbc=jdbc:mysql://localhost/foodmart?user=foodmart&password=foodmart;Catalog=/WEB-INF/queries/FoodMart.xml;JdbcDrivers=com.mysql.jdbc.Driver; Mondrian MDP Unauthenticated /WEB-INF/queries/FoodMart.xml

for /WEB-INF/web.xml, change connectString parameters

connectString

Provider=mondrian;Jdbc=jdbc:mysql://localhost/foodmart?user=foodmart&password=foodmart;Catalog=/WEB-INF/queries/FoodMart.xml;JdbcDrivers=com.mysql.jdbc.Driver;

When trying xmla queries, please replace FoodMart with Provider=Mondrian;DataSource=MondrianFoodMart;

Ubuntu package dependency error

lizhao — Thu, 04 Oct 2012 09:48:24 +0000

Trying to use quantlib/boost at Ubuntu, failed to install at both Ubuntu 12.10 and 12.04, due to wrong package dependency.

For ubuntu 12.10, libquantlib0-dev needs libboost, which is a dummy package pointing current libboost package (boost 1.49), however, libboost-program needs boost 1.50, so that you cannot install both packages.

An easier way to bypass this problem is to:

1. apt-get source boost-defaults 2. cd boost-defaults-1.49.0.1 3. vi debian/control (then replace all 1.49 with 1.50) 4. dpkg-buildpackage -rfakeroot -b 5. install required deb generated

PDFEdit code example I used to remove background of powerpoint slides.

for (i=0;i<188;i++) { cnt = page().getContentStream(0);


    it = cnt.getFirstOperator().iterator();

    while (!it.isEnd()) {

        num = it.current().childCount();

        if (num>2) {

            if ( "q" == it.current().childs().element(num-2).getName()) {

                it.current().childs().element(num-2).remove();

            }

        }

        it.next();

    }

    PageSpace.nextPage();

}
