Today I download the Windows binary version of the Apache Tomcat , after I follow the guide to install the tomcat , when I using the command line startup.bat the tomcat, a command prompt out then close automatically. while the command prompt only show this. Another command prompt is come out but exit automatically and the Apache tomcat Server is not start which test it using the browser key in localhost:8080, but turns out is connection timeout. I look through the startup.bat and found that it call catalina.bat with no arguments. The catalina.bat is too long , very lazy to look at it. I try to google it the way to stop the pop up command prompt close. Ok , no more story straight to the solution: 1) Type in "catalina.bat run" at the bin directory of your apache tomcat folder.(or in baby step type in "C:\tomcat\bin\catalina.bat run" replace the tomcat with the name of your Apache directory) 2) Then it come out the logs cannot create logs  org.a...

Spanning tree protocol is a network protocol that is used to ensure a loop-free topology. The basic function of the STP is to select which port will be use if there are occurs in redundant link which act as backup if the active link fails.The inventor of the STP is called Radia Perman, which is a software designer and network engineer, How the STP works? Root Bridge(bridge and switch is same thing) --> switch with the lowest mac address become root bridge,if and only if the priority is same Elect Root Port (RP) --> root port is port on the non root bridge pointing back to root bridge depend on speed (higher speed == lower cost) and port id (lowest port id win) Elect Designated Port (DP) --> port at root bridge pointing toward non root bridge Elect Non-designated Port (NDP) --> port on non-root bridge pointing towards root bridge that is block automatic become standard port The switch will sent Bridge Protocol Data Units (BPDU) to nearby switch (default sent every...

An agent is a computer system that capable of flexible autonomous action. While Agent architecture is the model for software agents and intelligent control system. Basically there are 3 type of architecture which are: Symbolic/logical (Proactive) Reactive Hybrid Symbolic Architecuture Symbolic Reasoning Agent At the beginning, all the agents is designed were symbolic reasoning agents. It is the expressions that can propose to the agents to use the expression logical reasoning to decide what to do.  To build an agent, there are exist a classical approach which is to view the system as a particular type of knowledge-based system. This paradigm we called as symbolic AI, it contain the intelligent behavior can be generated in a system by giving that system a Symbolic representation of its : Environment Desired behavior Syntactically manipulating this representation Symbolic is an architecture that : contains explicitly represented, symbolic model...

Practical reasoning is reasoning directed towards actions , which mean that it was the process to figuring out what to do. It weighing conflicting considerations for and against competing options, where relevant consideration are provided by what the agents desires/values/care about and what the agents believe. Example of practical reasoning: Mr Wong want go to Beijing, he think about the route to take to get to Beijing. He can use direct Beijing route which is faster and scenic route is longer but more enjoyable with less traffic. He in hurry but could probably arrive on time going either way. He eventually make a decision. This is the reasoning of Mr Wong goes through while deciding on what route to take is practical. He is deciding what to do. Differ from practical reasoning, theoretical reasoning is directed toward beliefs, which mean the process what conclude corresponding sense leads to belief and expectation. Example of Theoretical reasoning: At about the same time...

Android File transfer basically got two method or format which are Media device (MTP) and also for camera (PTP). However , the MTP is only suitable for windows or Mac computer, it was not compatible with the Linux. The PTP only allow you to transfer photos only but not others files. However you can let your ubuntu to support mtp by using the "mtpfs" or "jmtpfs". Below I will show step by step how to configure the MTP service in Ubuntu 14.04 LTS. First of all you need to install the mtp tools in linux, you can install by using the commands below. Open the terminal and type in the following 2 line. (ps:without the quote, and it may required you to key in your password) "sudo apt-get install libmtp-common mtp-tools libmtp-dev lilbmtp-runtime libmtp9" "sudo apt-get dist-upgrade" 2nd Step you have to edit the fuse.conf file. Fuse provide a secure method for non privileged users to create and mount their own file system implementation. =| You...

This tutorial is for Linux Distro that using bash in terminal, in my case is Ubuntu. If you just set the PATH just using the "export" command  , it wont able to set it permanently and will disappear after you close the terminal or restart computer.So follow the procedure below to set the PATH permanently. STEP: EXAMPLE SETTING JAVA Jdk-x-x-x at =usr/local/jdk-x-x-x 1) Open the terminal. 2) Type in the command "cd ~" 3) gedit .bashrc 4) Put the command "export PATH=$PATH:/usr/local/jdk-x-x-x" at the bottom of the .bashrc 5) Save it and exit gedit. 6) then type in the command "source .bashrc" You can try type java inside the terminal. restart the terminal and try. =D hope it help.
