best hackathon ideas

Two months ago, at the invitation of the editor of the silver bullet magazine, he wrote an article on "process" and "microkernel, the title is "microkernel process engine design ideas and architecture ". Now the seventh issue of panyuan magazine has been published, and the full text is now transferred to my blog. The original address of the silver bullet: http://gocom.primeton.com/modules/gSpace/modules/techresource/article1803.htm After reading this

,. NET is much worse than Java, and in recent years, often Wangxiao a year than a year of bright.Second, to say some personal superficial viewsFrames and tools in 4.java. NET most also have, Java EE ssh,. NET can be found similar to ASP. Spring.net (or Castle Windsor) + NHibernate (or EF). In other words, it will be used. NET Platform framework and tools, will soon be able to get started with the Java Platform Framework and tools, because the idea of connecting.5. Java and. NET development metho

Linux system, here are a few suggestions: 1, when see *.tar, *.tar.zip, *.bz2, *.gz, *.rpm and other package files are, more skilled use of the man command, view tar, unzip, bzip2, RMP command execution instructions to help the correct management of the file; 2, for some of the installation components (from the official package), timely find the appropriate official documentation, according to the instructions of the document to operate; 3, the work, to timely and their direct responsibility to

. The distance difference between the elements on each row adjacent to the vertical column is a period, for example, when n=4, the period is 2*4-2 = 6, the element 0 and 6 are 6, the elements 1 and 7 differ by 6.In each row in the middle, there is an oblique element in the middle of each of the two vertical columns, for example, 1 and 7 are 5,7 and 13 in the middle is 11. The middle oblique element differs from the element on the previous vertical column to a period of -2* row index. As can be u

First, the basic concept1.collecction: A sequence of independent elements that obey one or more rules. Lists must hold elements in the order in which they are inserted; Set cannot have duplicate elements; queue determines the order in which objects are produced by queuing rules 2,map: Mapping table, a set of pairs of key-value pairs of objects, allowing the use of keys to find values1 PackageHolding;2 ImportJava.util.*;3 4 Public classsimplecollection {5 Public Static voidMain (string[] a

In this event, you should free up any critical resources (such as files, graphics objects, database connections, and so on) that might be used.After this event, and finally, the browser receives the HTTP response packet and displays the page.SummaryThe ASP.

Web pages are composed of controls that produce rich HTML-based user interfaces and can interact with the user through events. Previously, settin

testing, improve software quality.Coupling is also known as inter-block linkage. A measure of the degree of connection between modules in a software system structure. The tighter the connection between the modules, the stronger the coupling, the less the module's independence. The coupling between modules depends on the complexity of the interface between modules, the mode of invocation and the information transmitted.Cohesion Keyword: The most adequate use of each element of the function of th
