Mixture (Sanskrit - मिश्रण) of Interesting Topics

It is a simple problem, and many of us must have had such problem either in exam or exercises or math-quiz or may be in real life. There are many ways to solve this, here is one efficient way to solve it. I do not claim it is to be most efficient or the only method. I found it out so I thought its good to share. It is not programming, its just logic. Consider three numbers a, b, c First I will put the (what I think is) dumbest way - step by step, considering each scenario,  //Finding 2 biggest numbers from list of three numbers i.e. a, b, c //Considering all values are different like 12, 45, 48 if( a>c && b>c ){ "Two big numbers are a & b" }else if( b>a && c>a ){ "Two big numbers are b & c" }else if( a>b && c>b ){ "Two big numbers are a & c" } //in case any 2 values are equal like 22, 22, 1212 //so there are three cases either a=b or b=c or a=c //a=b case ...

Here is one interesting modification to LOVCombo ux plugin in ExtJS 3.4. The original ExtJS ux Lovcombo i.e.Ext.ux.form.LovCombo plugin was developed by Jozef Sakáloš and can be still found at  http://lovcombo.extjs.eu/ . In Ext 4.x onwards, similar modifications can be applied to combo-box through plugin property. Following modification to Ext.ux.form.LovCombo, enables it to have "Select All", "Deselect All", "Text Filtering on values", "bubbling up and down of selection events". Its just a toolbar added in xtemplate of combo-box's dropdown list, and this toolbar has all these buttons, filter text-fields, etc. Here is how it looks like - It has five features - 1) Select All / Deselect All checkbox - to check/uncheck all values and its not part of your data, so selection / deselection logic is separate from user's data. 2) Text Filter - In case of long lists, this will be handy, to filter out values and select /deselec...

Before I start today, I would like to clear that these are not my tweaks, or code snippets. While searching for a solution to one of my problems, I came across these short, cool things for Windows. These can be helpful for me too in future, if I forget these tricks, so I am posting them here. 1)  How to open Command-prompt in a windows directory location directly :- When you open command prompt in windows, it by default opens in desktop directory in XP or in windows-7 it opens in that user's home-space directory. And if you open cmd using "Run as Administrator", then it opens up in "C:/windows/system32" folder. There are multiple ways to open command prompt at a particular directory location in windows- Traditional (dumbest one) is navigate to that directory using cd (change directory) commands. Go inside your directory (the directory in which you wish to open command prompt), and hold Shift key and right-click (inside that directory) , a...
