sourcecodemania

Source Code Mania It is an interactive warehouse of programming source code and tricks. A tool to learn watching peaces of code or to simply store our code and keep it for future work. It is interactive since it doesn't only allow to consult the available code/tricks until the moment, but ... [More] rather, also, it allows the users to incorporate his own. A place to search solutions to our work , a place to store and organize our source code (funcitons , procedures, classes, and more) and when needed ,search a posible solution here copy , paste modify and use. Will be available to store code of: Delphi , Visual Basic, Java , C++ , PHP, Python and more, with a syntax highlated colored editor. The project mission is create a tool to help us the programmer to keep or source code organized in section acording to categories , like databse , file system ,gui, etc ... thinking in future works why to code again something that was coded???? add it to Source Code Mania(SCM) database and in the future , before code something search if it is something helpfull in the SCM database and dont lose a preciated time thinking how search it first ;-) this is the mission , help us to have more time sorry by my english !!!!

store4j

简介在Message系统中，经常会有数据大量的保存，并且在很短时间内删除的需求；很明显，这样的需求采用数据库是不合适的，本项目实现了通过文件来保存这类数据的方法。 ... [More] 在现在的硬盘数据存储中，对性能影响最大的就是随机读写，为了增加这个存储的性能，采用了以下方式避免大量的随机读写： 数据文件一直增加，顺序在文件后面添加数据，避免随机写。 不存在索引文件，通过一个日志文件来记录操作，也是顺序写日志文件。 索引建立在内存中，取数据是先通过内存中的索引获取数据位置，进行访问（该步骤存在随机读操作，但是由于索引在内存中，只会有一次读操作） 初始化时需要通过日志文件恢复内存索引。 由于数据是一直写的，没有回收操作，可能会导致数据过大，这里解决的办法是每nM作为一个文件，并且加入引用计数，当文件不存在有效数据后，删除之。 通过上面的方法，可以解决文件的读写性能，但是也会有一些限制： 索引在内存中，会引起数据不能过大（每个索引占用60字节左右） 数据不能过于分散，否则会导致数据文件不能被有效清理。 性能PC机可以实现每秒万次的读写删操作。 应用该存储方式比较适合消息发送、消费类的应用，现在应用在淘宝网notify系统中。 [Less]
