Hello World,           I was having one weird issue with an Android device and that is key code value is 229 and I wanted to prevent it. What I wanted to Achieve? The numeric keyboard on android device The keyboard can only press 0-9 digits no dot or no + - or anything limit character to 4 digit What is the problem? I was using onKeyUp or onKeyDown and more, but I was getting 229 or couldn't get the value at all.

Suppose originally there were 3 commits,  A , B , C : Then developer D created commit  D , and developer E created commit  E : Obviously, this conflict should be resolved somehow. For this, there are 2 ways: MERGE : Both commits  D  and  E  are still here, but we create merge commit  M  that inherits changes from both  D  and  E . However, this creates  diamond  shape, which many people find very confusing. REBASE : We create commit  R , which actual file content is identical to that of merge commit  M  above. But, we get rid of commit  E , like it never existed (denoted by dots - vanishing line). Because of this obliteration,  E  should be local to developer Ed and should have never been pushed to any other repository. Advantage of rebase is that  diamond  shape is avoided, and history stays nice straight line - most developers love that!
