How to take care of your leather seats ?

Use hair dryer to remove wrinkles from leather seat.
1. Wipe down the leather seat with mild soap and water or a specifically formulated leather cleaner. Use the cloth to rinse and dry the leather seat so that no soap or cleaner residue remains on the surface of the leather.

2. Inspect the leather seats and find all the places that have wrinkles.

3. Turn on the hair blow dryer to its hottest, strongest setting.

4. Position the end of the dryer eight to 10 inches away from the wrinkled leather surface. Move the end back and forth so that the hot air from the dryer is not hitting a single portion of the leather for too long. This prevents the dryer from burning the leather.

5. Wait for the wrinkles to disappear. The heat from the hot air in the dryer will gradually shrink the leather, tightening its surface and effectively removing the wrinkles. Hair blow dryers operate at a lower temperature than the professional heat guns that are typically used to remove leather wrinkles. As a result, it might be several minutes before the wrinkles are completely gone.

6. Apply a light coat of premium leather conditioner and work it into the surface of the leather. This helps to protect the leather from the environment, and it might prevent or minimize future wrinkles. Buff lightly with a cloth. A high-quality leather conditioner might cost slightly more than some other brands, but it has less wax and can extend the life of your leather. Popular leather conditioners include Mothers Leather Conditioner and Meguiar's Gold Class Rich Leather Cleaner and Conditioner. Such products may be purchased at your local automotive store or online.

How to generate a thread dump ?

Generating a Thread Dump
Windows
The Java application that you want to produce a thread dump for must be running / started in a command console. When you want to produce a thread dump press Ctrl-Break
Note: it's easier to produce a thread dump on Linux as the JVM doesn't need to be started in a console window.
Linux
If the JVM is running in a console then simply press Ctrl-\.
If the JVM is running in the background then send it the QUIT signal:kill -QUIT process_id

Note: the thread dump will show on the console where the to-be-kill process is running on, not the console where you issue the kill command.
