  FUCK PASSWORDS

I'm so tired of passwords. So, so, so tired. Most people don't understand this. Most people use the same password everywhere. Most people can just mechanically type out password3 in every password box, smirking to themselves at how clever they are, because who would ever guess 3 instead of 1? I don't do that. Let me tell you what i do. I generate a different password for every service, based on a convoluted master password and the name of the thing. I do this because it's what you're...

  Data Scientists and Their Harder Skills than Big Data

The field of data science is often confused with that of big data. Data science is an aid to decision makers in a company with a logical approach.  Who is a Data Scientist?  A Data Scientist reviews a huge collection of data(that may extend to a couple of terabytes of disk space or thousands of excel sheets). This humongous chunk of data is not feasible for being handled, sorted and analyzed by a single person. Here we require the help of data science, and most recently, the field of A...
