1. I plan to build my own website. It is purely learning new technologies recently. Client: Uses Silverlight as the client.Database: cloud computing is used.Server: ASP. net mvc is used as the server. The first idea is to use Silverlight, embed web pages into Silverlight without using JavaScript technology, that is, develop the Silverlight full site. The second idea is to use the Silverlight technology t

In the 2013, the field of cloud computing became more of a noun "Docker". Known for its light weight, it's better to solve application packaging and deployment. We've been building IaaS before, but it's quite complex and complex to achieve unified functionality through IaaS. Encapsulation of particularity into the image to achieve an almost consistent deployment method, it is "Docker", the container as the

Today, I checked Sina's public cloud computing platform Sina App Engine. I just looked at development-related things and didn't actually do anything. I feel that there are still some gaps in conventional Web servers.ProgramIt should take a bit of effort to transplant (this should be consistentCodeThe writing quality is related, and a good design should not be changed much ). After reading the development i

returning? Yes, why do you have to update it regularly? The answer is very simple, because if the majority of the cache is the latest data, only compare the version without the actual update operation, the performance is very small and small, so the regular update, in the event of slave node downtime from the backup node to work, a great help.Finally, say the push (push) mode, that is, every time a data change is forced to update all caches. This approach consumes performance, but is more secur

, sort, uniq, tail, head to analyze the log, then you need to Splunk. Can handle the regular log format, such as Apache, squid, System log, Mail.log these. Index all logs first, then cross-query to support complex query statements. And then show it in an intuitive way. Logs can be sent to the Splunk server via file, or it can be transmitted in real time via the network. or a distributed log collection. In short, a variety of log collection methods are supported.

The current core workload is still running on the enterprise-level system platform.The reason for this is that we are not mature enough in cloud computing technology. We process and analyze client data,AlgorithmThe design is not smart enough. In the current view, tens of thousands of clients only serve as the port for collecting information, but do not implement intelligent data processing.

Python version, the different version of the compiled PYc file is different, 2.5 compiled PYC files, 2.4 version of Python is not executable. Why need PYC file: This demand is very obvious, because the py file can be directly see the source code, if you are developing commercial software, it is impossible to release the source code too? So it needs to be compiled into PYc and then released. Of course, PYC files can also be anti-compilation, different versions of the compiled PYC file is dif
