Open SourceCommunityThere are often a lot of projects that are unexpected, and people are often excited. For example, the pearpc that runs the Apple Computer System on a general PC. Convert Microsoft Game console Xbox into the Xbox-Media Center of the home audio and video center, and install linux ipodlinux on the iPod. Of course, there are also many outstanding open-so

C # high-speed, high-performance, open-source log writing code,1. Requirements
The requirement is very simple, that is, writing logs at high speed in C # development. For example, in high concurrency and high traffic, logs must be written. We know that the program is time-consuming when operating the disk. Therefore, writing logs to the

4. LinkedIn's Kafka
Kafka is the December 2010 Open source project, using Scala language, the use of a variety of efficiency optimization mechanisms, the overall architecture is relatively novel (push/pull), more suitable for heterogeneous clusters.
Design objectives:

For daily terabytes of data collection, these systems typically require the following characteristics:
Construct the bridge of application system and analysis system, and decouple the association between them;
Support for near real-time online analysis systems and offline analysis systems like Hadoop;
With high scalability. That is, when the amount of data increases, it can be scaled horizontally by increasing the nodes.

, it is dependent on the Actionbarsherlock project. There is also a problem in the code that needs to be changed to inherit Sherlockfragmentactivity (that is, actionbarsherlock in the slidingfragmentactivity). Because this question I also looked for for a long time did not solve (has not doubted the code problem), then really did not look at the code to discover.

If a Web site has a duplicate site structure, using a database that is intermittently updated (rather than continuously updating the database), the same results are repeatedly searched, and the performance and scalability of the cache can be improved by performing a caching approach.EHCacheEHCache is a pure Java in-process cache that has
