Recently I have been through the 1 and 2 . Here is some notable things to remember as an effective learner. The idea is to study more is not necessarily effective. Instead, it may worst the performance. One of the underlying theory is that things are reinforced when we tend to do more off. Things that are punished or ignored when manage to do less off.  Rules It is worth to note down few rules 1. Rule the moment you started to slide, you're shovelling against the tide.: take a break. Pomodoro technique there are two modes in your brain _focus mode_: tight pattern of Knowledge control your thinking. There is very less opportunity to grasp the new things or being creative. _diffuse mode_: the relax mode. Models of knowledge are weakened. Ready for the new concepts.

I have to separately upload the images to google photos. However later found the iPic image upload app which work with typora . But following two work flows are efficient as I found. Blog workflow this is how I create my new blogs. The basic tools are as follows: iPad Apple pencil MWeb app here the benifs of this workflow: I can work on same document both iPad and the mac computer Mweb support images and Malh for my documents In addion to that , Mweb publishes the web blog post to my Blogger site.

The main challenge is to debug the remote tomcat server via SSH port 22 only because that is the only allowed path. Even I cannot ping the server. Instead of catalina.sh, I have to always run the "sudo service tomcatx start|stop" because tomcat is installed as a service using redhat yum. From this blog I found the details to setup the tomcat. I changed the TOMCAT_HOME/conf/tomcat6.conf file to have the following JAVA_OPTS JAVA_OPTS="${JAVA_OPTS} -Xdebug -Xrunjdwp:transport=dt_socket,address=15005,server=y,suspend=n" This is just a one line.
