Scientific Thinking in Business
While data is essential for scientific decision making, theory, intuition, and imagination remain important as well—to generate hypotheses in the first place, to devise creative tests of the hypotheses that we have, and to interpret the data that we collect. Data and theory, in other words, are the yin and yang of the scientific method—theory frames the right questions, while data answers the questions that have been asked. Emphasizing either at the expense of the other can lead to serious mistakes.

7 ways to transform into a connected leader
According to Delight Leadership Inc., a ‘connected leader’ is one who holds him/herself in high regard. These leaders take their personal care and growth seriously, and understand that in order to develop as a person and to lead thousands in a transformational way; they must first do the work – the inner work that lets them evolve into a better version of themselves (that can in turn profoundly captivate and influence others). Here are 7 Ways to begin to transform into a Connected Leader:

CIOs need a System of Engagement with the CMOs
CIOs are being asked to fast-track the implementation of Systems of Engagement. What options does the CIO have? Moore explains that the demand for Systems of Engagement is driven by the need to collaborate in the disaggregated ecosystem we find ourselves in today. Compelling technologies are easily accessible in the social media that control our personal lives. We get so used to (and spoiled by) these technologies that we expect the same experience at work.

Can problem solving be taught?
“Good innovative problem solving has to be collaborative,” he says. “You can do it on your own, but group conversations can spark new thoughts and solutions much quicker than individuals will. It will also, usually, be a much richer experience and, if you’re going to teach someone problemsolving techniques, then they, at least in part, have to be able to run a team of problem solvers.” The trick, it seems, is for leaders to design and empower teams to break problems down and design solutions.

Location-based services: Controversy at every level
Overall, location-based services use three different levels of accuracy -- vicinity to within a block or two (derived from GPS coordinates), presence (establishing that you are inside a given building or store) and department (pinpointing your location within a given store). Shopkick makes use of the presence level, primarily; it's also the level that's demonstrating the most commercial success and producing the most fears about Big Brother-style surveillance.

Dueling R and Python, Contest 1A
The Python and R code in this admittedly simple example is remarkably similar. Indeed, driven by the numpy/pandas libraries, Python reads more like R than it does core Python. Python/pandas is the performance winner with this exercise on my 16G Wintel notebook. In the early morning with plenty of wifi bandwidth, both download/unzips complete in about 10 minutes. The data frame creations, though, are much faster in Python-pandas than they are in R – 2.5 minutes vs 14 minutes – probably to some extent reflecting the R kluge for column selection.

7 Principles to Enable Agile Projects Through Enterprise Architecture
The strategy, governance and co-ordination of this changing landscape is often referred to as Enterprise Architecture. At this point you might be wondering there is a way to join Agile projects with EA in perfectharmony. If there is, I haven’t discovered it. What I can offer you is some principles, based upon what has worked in organisations that I have worked with.

Using Auto-Classification to Improve Your Information Governance Practices
Governance is still lacking in many organizations as around 85% of users still manually identify records, but are not clear which content is valuable and not valuable, and as a result, there is considerable fear towards the regulatory impact of deleting information. New auto-classification technologies can take the burden off the end user by eliminating the need for them to manually identify records, by providing automatic identification, classification, retrieval, archival, and disposal capabilities for electronic business records according to governance policies.

Sizing Up the Changing IAM Market
"The cloud versus enterprise divide to IAM was never a comfortable situation, but had become quite clear cut," says Andy Kellett. That's why Salesforce's move to offer an IAM that can be applied to both cloud and on-premises applications "breaks the mold," he says. ... Despite the moves by Salesforce and Microsoft, many organizations will still choose to work with separate IAM providers if their systems' features and capabilities match their needs, Gartner's Iverson says. However, the pressure is on these IAM providers to demonstrate why their technology is worth the extra investment, he says.

Highly-Available Load Balancing of Apache Tomcat using HAProxy, stunnel and keepalived
This article will describe the process required to set up a highly-available SSL-enabled load balancer using HAProxy, stunnel and keepalived to front a pair of Apache Tomcat instances. The configuration will start off simple, and extend and grow as more functionality is added. First, a session-aware HAProxy load balancer is configured. Next, Tomcat clustering is configured with session replication and the responsibility for maintaining session state is moved to Tomcat. Then, keepalived is added – providing a failover IP between HAProxy instances running on two nodes.
