packets on the Linux NAT router in the replacement IP header does not consider tracert this function, directly changed, and then passed directly to the destination address, the destination address has an ICMP echo Reply. So I'm 2.If you use Traceroute on Linux, the UDP protocol is used by default, except for the first hop, the rest is * * *. Probably is due to the virtual machine NAT router, which discards the port>32767 package by default. So it's all explained. A complete.From: http://blog.cs

The screen (above the fold) refers to a screen that is visible to users without scrolling through the Web page screen. World famous Web usability expert Nielsen has reported that the first screen above the attention level of 80.3%, the first screen below the attention of only 19.7%. These two figures are enough to show that the first screen is important for every site that needs to be converted, especially the website of the electric dealer. 　　Related reading: E-commerce website Design

MySQL series: innodb source code analysis-redo log structure, mysqlinnodb In innodb Engine implementation, a redo log system is built to ensure transaction persistence. Redo log is composed of two parts: the memory log buffer and the redo log file. The purpose of this design is obvious. The log buffer is to speed up log writing, and redo log files to provide persistence for log data. In the innodb redo log

Data structure and Algorithm series catalogRecently took time to collate the "data structure and algorithm" related articles. In the finishing process, for each data structure and algorithm to give the "C", "C + +" and "Java" the implementation of the three languages, the implementation of the language is different, but the principle is the same. Therefore, the reader in the process of understanding and lea

In the first installment of this series, the installation of SEQUOIADB and the deployment of a (pseudo) cluster are briefly described.The second and third section of the SEQUOIADB cluster is simple to operate.In this article, we will make a simple analysis of the architecture of the sequoiadb.Because of their own limited ability, for the architecture of such a tall theme, dare not speak lightly. Therefore,

Complete analysis of array pointers and pointer arrays in C ++ (Series 1)Select blog from zosatapo Recently, we often see discussions about array pointers and pointer arrays at airports in forums. This is an indispensable step in learning C ++ and other languages,However, pointers are useful but difficult to use, so it is not easy to learn. Recently, I haveThere is no project to do, so you can write you

Spout can send a message if Overflow-buffer is empty and pending stores less than max-spout-pending, or if max-spout-pending,topology is not set to active Sleeps 100 milliseconds If the topology is inactive. Call Spout's Nexttuple callback method to send the message, Nexttuple will use the emit or Emitdirect method of the incoming Spoutoutputcollector to send the message. And eventually calls the

In order to solve the suspension problem and promotion failed problem, finally I set up-xx:survivorratio=1, and maxtenuringthreshold removed, so that there is no pause and there will be no promotoin failed, And more importantly, the old generation and the permanent generation rise very slowly (because many objects can not be recycled in the old generation), so the CMS e

architecture of ES, because of the invariance of event records, also makes it easier for us to migrate data. Moreover, we also make reasonable use of the features of the CQRS architecture, that is, the update of the read library is entirely based on the event table. So, as long as we ensure that the event tables are absolutely fully synchronized, it is always possible to ensure that the last read library can be completed synchronously. This is also very cool.Finally, the question I'm thinking i
