"To be as precise as we possibly can is not a luxurious mannerism that the academic prig can afford himself in his (supposedly!) sheltered environment; for people facing the problems of "the real world" it is a Must." --E.W. Dijkstra, An Open Letter to L. Bass

From In Some Cases illustrating drawbacks of SQL in data computing and analytics: 

The computing power of SQL for mass structured data is complete, that is to say, it is impossible to find anything that SQL cannot compute. But its support layer is too low, which can lead to over-elaborate operation in practical application.

One of the four aspects of this "over-elaboration" is "computation without substep", but before we comment on it, the article glosses over an important matter.

Hey There Little Electron, Why Won't You Tell Me Where You Came From

Fascinating.

Israel is holding back channel talks with the 'Palestinian Authority' relating to Gaza, in which it is making concessions and receiving nothing in return.

The Tower cites a Wall Street Journal report that indicates that Western negotiators are so desperate for a deal with Iran that they are offering more significant sanctions relief for a deal that would not stop Iran from developing nuclear weapons.

The Wired article Ex-Googler Shares His Big-Data Secrets With the Masses touts a new tool that "mimics the way web giants like Google and Facebook rapidly analyze enormous amounts of online information." The article calls the tool "simple for analysts to query data from anywhere in a company with a single tool, regardless of where that data is stored, without the need to learn new programming languages."
