Mr Yan Xin, Senior Development Manager of Microsoft, finished reading the famous "migration path". Before reading it, he thought that if he only looked at the directory, what kind of questions do I have or what do I want to know most? Today, after reading a book, you can select a few topics you are interested in and share them with you in Q . 1. Q: What do you think?CodeReview and pairing programming?

porting libraries requires considerations (how the files generated by the migration Library are used) General induction of the migration of simple libraries 1. File location After migration general Select a new folder under the opt/directory, such as Opt/lib-codec 2. Configuration options typically require the identification of compilation tools and link Tools ,

Through the previous introduction we know that the main line link is due to the db_block_size of the database is not large enough for some large fields can not be stored in a block, resulting in a row link. For row links We have nothing to avoid except to increase db_block_size, but since the database was built Db_block_size is immutable (before 9i), we can specify different table spaces for the oracle9i database db_ Block_size, therefore, the production of line links is almost inevitable, there

The original Web project was run on Weblogic8, but now the requirement is to run into JBOSS5, preparing for a later migration to a later version of JBossBecause I did not study WebLogic, so the previous steps have been carried out by others, in the half of the time, due to certain circumstances, and gave me to complete.At this point he encountered two main problems, the following is the main log:2016-03-31 03:36:59,787 ERROR [org.apache.catalina.core.

Cocos2d-x provides the source code for the Libnetwork library, and it also provides visual Studio 2012 project file Libnetwork.vcxproj for the Libnetwork library, which makes porting easier.Tip Some cocos2d-x engineering templates in the solution, there are already libnetwork libraries, the process described in this section is not required.Since the bottom of the Libnetwork library is dependent on the Libcurl library, we will first migrate the Libcurl library as described in the previous section

can be obtained (which is the inverse of the eigenvalue matrix), and this c is the required composite transformation matrix.For each image to be processed, there are different transition matrix C. The values of the lαβ color space are calculated by using the adaptive processing of color images and shape images. Instead of using a fixed c to process all the images. Although this algorithm pays a little price in the computation time, the adaptive method accords with the color distribution of the
