Gartner positions Microsoft as a leader in the Magic Quadrant for Operational Database Management Systems

This is the new Gartner magic quadrant for operational (transnational, OLTP) DBMS (Oct., 2015). It appears that Microsoft’s hard work and licensing structure pay off to beat Oracle. I was hoping to see the rankings of big data vendors, such as MapR, Cloudera, Hortonworks, and others, to be a lot higher but they are not. Maybe, big data applications are still limited to a few big name companies such as Google, Amazon, or Netflix, but not the majority of businesses. And, those big data businesses are more related to streaming and internet searches, less about point-of-sales and logistics operations. Or, maybe, traditional DBMS is already sufficient to meet most business needs with reasonable cost.

An Amazon ‘pick-up’ store may be coming to a college near you

9/14/15 Mailroom by Mei Buzzell Students mail waiting

It makes perfect sense for Amazon to set up physical stores, or join existing Barnes and Noble stores in college campus, due to its shipping convenience and popularity in colleges. This would eliminate the need for those colleges to set up distribution centers in their campus, which is an completely unnecessary infrastructure cost to them.

Some people even suggested Amazon to buy out Postal Services. This is another interesting idea but does not actually solve the package problems to those colleges, because they simply do not have the space and labor to handle those increasing packages.

The link between gun deaths and gun ownership: What we know

Unfortunately, there is no strong evidence between the gun ownership and gun related homicides, as shown in the scatter plot below for homicides, i.e., an almost flat and horizontal line. The linear correlation between gun ownership and gun violence is mostly explained by gun related suicides, not homicides. The debate goes on.
