Samsung Wi-Fi PSM issue.

Sometimes samsung mobile users experience issue with their wifi connectivity. The icon shows it’s connected to wifi but wifi won't work. This is because of the wifi power saver mode (PSM) is set to ON.  
Wifi PSM (power saver mode)
Wifi uses more power. So system is designed to turn off or disable the wifi when the user is not using the internet! Some times this prediction fails, machine thinks you are sleeping even though you are actively browsing the internet and hence it switches of the wifi! So you run out of internet connectivity!
How to fix

To fix this disable the power saver mode. Set it to off.
Steps to disable wifi power saver mode. 
  1. Go to dial pad
  2. Dial *#0011#
  3. You will enter into the service mode screen
  4. Click the menu at the right corner
  5. Select Wifi
  6. You can see the Wifi Power Saver Mode button and it reads ON
  7. Click it and turn it OFF
  8. Exit the menu
  9. Try now - it should work without any hindrance. If not delete your wifi setting and rejoin to the wifi connection again!

Log4j multiple WAR files in single EAR configuration

Log4j multiple WAR files in single EAR configuration Problem: When you have multiple WAR files under the same EAR with multiple log4j config files in each of the war files, the logging API will pickup the first available config file and ignores the list. i.e, only a single log4j config file applies to entire EAR. Consider the below app app.ear |__admin.war    |__WEB-INF/classes/log4.xml |__web.war    |__WEB-INF/classes/log4j.xml When you deploy this app to the server all logs of two war files admin.war and web.war will go to admin.war' log. The log4j.xml in web.war has no effect here. There are some complex solutions for this like adding a logback, specifying package level log files in log4j configuration etc. Solution The easiest way is configuring the context param in web.xml In your web.xml add the following context param will send the log4j config locations specific to the contexts and fixes this issue. web.war/WEB-INF/classes/log4j...

Ubuntu cursor jumping problem Issue : When you type in Ubuntu/Kubuntu you may get annoyed by cursor jumping here and there in the screen. This happens across all the applications. You might have tried adjusting key board settings, key stroke speed etc. But this is not related to your key board, but the touch pad! Cause: The cause of this issue is your touch pad. Yes, while typing parts of your hand/fingers often touch the keyboard. In windows this touch will not be deducted while typing. But for Ubuntu it is.  So when you type something and un-intentionally unknowingly touch your touch pad will take your cursor to the appropriate mouse position with respect to your touch forgetting you are typing something!!! Solution: Simple. Say your touch pad not to care the touches while I am eagerly typing something important.. How to say that? Open Synaptix Touch pad manager  Check Automatically switch of touch pad on keyboard activity Time to wait before switc...
