Calculate all keys of maximum times occurring value from HashTable in JAVA  ------------------------------------------------------------------------------- Recently one of my friend had come across one problem, where he had a hashtable (or just consider its just a key/value map), and in our case it was of type Hashtable(String, ArrayList(Long)) and now the arraylist size may vary, it can have duplicate long type values. and he needed to get the maximum times occurring long number's all keys from values ArrayLists (i.e. for which all keys its present in values ArrayList) So we did it this way - Its just my try,  as it was a interesting programming challenge, so posting for others who need this kind of data mining in java (logic remains same for other programming languages too) FileName - LogicProHashTB.java //FileName - LogicProHashTB.java package logic.others; import java.util.ArrayList; import java.util.Arrays; import java.util.Collection; impor...

Here is one more interesting search query by Google, 1) Open Google.com (Make sure you have enabled .. Google Instant search) 2) Type " let it snow " 3) and hit search Wait... Now you will see snow and fog all over your screen as if you are having heavy snowfall on your screen. Only button "defrost" will be visible on the screen, anything else will be invisible in heavy icy fog. One more interesting search query on Google is - askew - It has same effect of "TILT" query, as i had mentioned in my previous blog about " Interesting Google ", it tilts search results screen to left by few degrees. recursion - It gives "you do you mean - recursion" all the time, as meaning of word recursion. I hope Google engineers will also have "let it rain" query implemented soon. Anyways thanks Google for being innovative.

Now-a-days, a talk-show on CNBC TV18 channel named "Business Sutra" is making news. Its a talk-show between TV anchor Menaka Doshi and Devdutt Pattanaik (Mythologist) who is also Chief Belief Officer of Future Group. The talk is about, is there a Indian way of doing business and what are they, and what Indian mythology teaches us about business, and what is ethically right in business according to Indian mythology... a worth watching..  I believe its a worth sharing video link - I am giving link to the first Episode of this talk show, other links you can easily get in YouTube.

Sometimes when you try to start a process/application (mostly observed during server start ups), we get exception/error saying xxxx port is in use cannot start process/application. Sometimes I get this exception while starting application servers like JBoss, WebSphere, WebLogic, etc and even sometimes with DB servers installed on my machine. This is even possible while starting a LAN Game, so here is short, smart solution. Actual problem here is we might not be aware of which process is using this port, i.e. which process to kill(if not critical). Use following commands to get to know - >>netstat -ano | findstr which gives you PID (Process ID) number, use this number to get process name - >>tasklist | findstr PID OR to get complete status about process, you can run (If you are running UNIX-based Applications on windows then few UNIX commands e.g.grep to would have been added to the Windows command shell) >>ps -ef|grep PID This will give you name of proces...

Google runs a daily puzzle challenge called "A-Google-A-Day". In order to solve the puzzle, you need to search in right direction and with right keywords from puzzle. Each day your searching skills will be tested for little more to get you ultimately to Google mastery. Each morning at 12:01 a.m. Eastern time you’ll see a new puzzle. If you are unable to get to right answer, you can check out hints, and still if you fail to find the correct answer, you can find it out there. But one thing for sure is that this will surely improve your knowledge by searching, reading and understanding. No matter whether you knew the thing you searched or its something you are/were totally unaware of. So don't waste any time and check out today's puzzle challenge at - http://agoogleaday.com

Recently I had a requirement where in our UI screen (which we have built using ExtJS Framework) we had a data-tree-panel and we wanted to expand that tree till a particular depth, and there is no built-in method available in API, so I had written a custom function (I think this will work for all versions of ExtJS). This is the code to expand the treenode to certain depth, i have written 2 functions, in which one function gets recursively called till it completes expansion of given node till its given depth or till it gets to leaf node. //This Function recurses through Every Node till conditions are met //Currently Depth is hard-coded to 4 but can be given a variable value to change as //per situation myfunction = function(Mynode){ if(Mynode.hasChildNodes() == false || Mynode.getDepth() >= 4){ return; }else if(Mynode.hasChildNodes()){ Mynode.expand(false); Mynode.eachChild(myfunction); } } //this Function expands given node till depth given //As of n...

In previous post, I had uploaded an image of a painting of famous people till today in the history of mankind, here are names of those which I was able to recognize.  Background images -   a) In right top-corner - Moai - These are monolithic human figures carved from rock on the  Chilean Polynesian island of Easter Island between the years 1250 and 1500. b) Stonehenge c) Egyptian Pyramids Names Of People from Painting :-  1) Charlie Chaplin 2) Saddam Husain 3) Pele - original Name - Edson Arantes do Nascimento 4) Vladimir Lenin 6) Aldolf Hitler 5) Mao Zedong 7) Steve Jobs 8) Bill Clinton 9) Vladimir Putin 9) Karl Marx 10) Goerge Bush 11) Genghis Khan 13) William Shakespeare 14) Ludwig van Beethoven 15) Mahatma Gandhi - Mohandas Karamchand Gandhi 16) Kobe Bryant 17) Mother Teresa 18) Leonardo Da Vinci 19) Yasser Arafat 20) Muhammad Ali 21) Albert Einstein 22) Queen Elizabeth II 23) bruce Lee 24) Winston Churchill 25) Abraham Lincoln ...

This is the image of a painting which I received few days back in a mail, actually its a painting of all important personalities since existence of human being. There are more than 100 world known   personalities  on this painting.   If you can name a   minimum of 25, you may consider yourself a well-informed person. I could recognize only 50-55% of names, but will try to collect others too. And will upload all the names in next blog.
