, coined by Joseph Schumpeter in Capitalism, Socialism, and Democracy
, refers to the process by which new innovations kill old inefficient products or processes. But we are not talking about that but instead, of destroying data to create more useful information. By destroying
, we mean altering the data currently loaded in memory with no undo
button to rely to. When you load or open data into Stata, Stata stores the data in your machine’s RAM. Any changes made, therefore, are not permanent or saved in your hard drive until you call on
, but still be careful that you do not overwrite your raw data files.

I tried Uber in late May and since then it has been 131 Uber rides covering 1,200 kilometers and 80 hours on the road. Uber (and GrabTaxi) has eliminated the wait under the heat (and rain) and the dealing with the assholeness of most taxi drivers here in Metro Manila. But what I love most about Uber, apart from their customer service, is the data they send. Trip receipts are automatically sent as soon as the trip has ended. These do not only show how much I am charged but include time, distance, fare disaggregated by time and distance, and many more. GrabTaxi receipts, on the other hand, only show amount paid and manually encoded by drivers.
