Human Computation - Outsourcing complex problems to Human


Computer technology has become more and more powerful over the last few decades. Yet still there’s a clear margin - actually a gap - between Computers’ (artificial) decision making ability when compared with human intellect. 

Filling out this gap is one of the most important problems that needs to be addressed, because this digitalizing world requires devices and applications that human can use more comfortably and effectively. Truth is, to make the human feels comfortable, the ‘dumb’ devices or applications should anticipate what he requires and consider his preferences. Therefore, artificial decision making algorithms should at least resemble (if not match up with) human intelligence.

SQL Query Result into Comma Separated List


During my work I had encountered a situation where I need to get a comma separated list as an output from the values in a SQL query result.

The Story Never Ends ! [UCSC Batch 6]

End of a journey, But still couldn’t believe it! Though it was already expected, I never realized that end of my undergraduate life would make me this much sad. Even though we (my batch mates, UCSC 6th batch, 2007/2008) are not graduated yet, yesterday was the final remarkable day at university for most of us except our friends who’ll be doing the fourth year.

Logins, Users and Guest users in MSSQL

Recently I was working with some database restoring and configuring stuff. And I was getting errors due to the conflicts on database users, server logins and their permissions.

In the ideal scenario, there should be a 'login' in the database server, and a corresponding 'user' for the database. Sometimes people get confused with the difference of these two. But they are for two entirely different purposes.

It has been a long time since my last post. I was busy with exams, projects and ofcourse with my first job! Few months back, we were supposed to do a project (topic selection was in our interest) which was essential for academic curriculum. So me and my friends were into virtual tour using available web resources and finally to provide a better user experience with GIS.
