Box Percentile Plot

This is a new addition to my diagnostic tool kit. I had never used Box Percentile plot before. However this week, I had to look at outliers in a data. Histograms are not that good for outliers. Box Plots, same story(though whiskers in the box plot are useful in getting an idea about the data points 1.5 IQR away from the boxes). I usually prefer Box plots for the simple reason that it gives a sense of the data from a quartiles perspective.

On Flow

Via Mihaly Csikszentmihalyi((pronounced “CHICK-sent-me-high-ee”) , Chicago professor and the author of one the most influential books,"FLOW" says , being in flow means : Completely involved in what we are doing - focused, concentrated A sense of ecstasy - of being outside everyday reality Greater inner clarity - knowing what needs to be done, and how well we are doing Knowing that the activity is doable - that our skills are adequate to the task Sense of serenity - no worries about oneself, and a feeling of growing beyond the boundaries of the ego Timelessness - thoroughly focused on the present, hours seem to pass by in minutes Intrinsic motivation - whatever produces flow becomes its own reward

Quote for the day

A programmer can write tens of thousands of lines of code, and produce a lot of software that works. A less productive coder can write a tenth of the lines, perhaps even editing down what she writes so that there’s less code, but they’re better written. This small program might be the most useful thing on many people’s computers, flawless code that just works. - Leo Babauta
