event has been processed. The agent can respond to the message of the event sent by the main object by updating the UI interface or other state of the object. Or, in some cases, return a value to affect how other upcoming events should be handled. The main value of the agent is that it allows you to easily customize the behavior of various objects. Note that the agent here is a noun, which is itself an object that is specifically representative of th

cache part of the JSP page or HTTP request without restriction, any Java object can be cached. Having a comprehensive Api--oscache API gives you a comprehensive program to control all the Oscache features. Persistent caching-caches can write to the hard disk at will, so it allows expensive creation (expensive-to-create) of data to keep the cache, even allowing the app to restart. Support cluster--the cluster cache data can be configured by a single parameter without the need to modify the code.

SummarizeLightweight applications and their dependent packaging and deployment tools The advent of Docker was an exciting thing, and the Linux community quickly adopted it and tried to use it in a production environment. For example, Red Hat announced in December that it will support Docker in the upcoming Red Hat Linux Enterprise Edition 7. However, Docker is still a young project and is

for storage pools.Memory at least 8GB (1GB for Ubuntu, then increase 1GB RAM per 1TB data added)Any decent CPU.Suggestions:I strongly recommend using the LTS (long-term support) version of Ubuntu on any file server.To create a raid-z, you need at least two SATA hard disks with the same storage capacity. If you have a hard disk with different capacity, the total storage will be the size of the smaller hard drive.I strongly recommend having a third external hard drive so that you can back up your

ScenariosBecause Redis is an emerging solution that offers more features, Redis is generally a better choice than memcached. Memcached may be a better choice in two specific scenarios., such as HTML code snippets. Memcached's memory management is not as complex as Redis, so the performance is higher because memcached's metadata metadata smaller , The extra overhead is relatively small. The only supported data type for memcached is the string string , which is ideal for caching read-only data be

Mozilla is working to implement JavaScript "parallel (parallelism) computing" to take full advantage of hardware performance. Dave Herman is the chief researcher and strategy director at Mozilla Research. In a recent blog post, he mentions that they are experimenting with their JavaScript engine SpiderMonkey.They tried to add a more flexible and powerful parallel computing primitive to JavaScript through a bottom-up, incremental approach. He first noted that: What I'm talking about is n
