The problem with project risk management
If risk management could prevent projects from failing or being adversely affected by external circumstances, all projects would be successful, and, clearly, they aren't. So should we bother expending time and effort planning for predictable risks that are a natural part of most projects? Would it be more effective to simply deal with the problems when they occur.
Prescriptive analytics is coming to a future near you
In prescriptive analytics, algorithms basically run wild. "We use rules, but minimally," Basu said. That's because rules don't scale. They are dependent upon human beings, and in a big data world, human beings cannot keep up. "You end up being as good as the guy making the rules." Instead, the algorithms are allowed to take over but are programmed to adapt automatically based on changes in established parameters.
Why agile isn't enough for many software projects
"It would be nice if we were all collocated in small teams, and we didn’t have to talk to anybody else, but that’s not a reality," Mark Lines continues. "What if you’re in situations where you need to more than what a classic agile project would ask for?" Examples of software projects beyond the scope of agile include applications subject to regulatory mandates, or complex programs such as software for rocket ships or medical devices.
Active/Active Data Center Design - Complexity & Challenges
Not only can it be expensive, but it's also complex. For example, if you share sessions across cells, this means that you're relying on a single database server (or database server and failover server), or trying to replicate data between data centers. As a result, maintenance on the database server(s) of any type results in an outage (or the steps to avoid an outage) across two cells. This adds complexity.
Wirelessly-charged electric buses start public route in South Korea
The power is transmitted wirelessly via Shaped Magnetic Field in Resonance (SMFIR), a technology developed by the Korea Advanced Institute of Science and Technology (KAIST) that essentially runs 100 kilowatts of power through some cables at a very specific frequency (20 kHz in this case), creating a 20 kHz electromagnetic field. The underside of the bus is equipped with a pick-up coil that’s tuned to pick up that frequency, and thus AC electricity is produced via magnetic resonance.
The cloud is a revolution-enabler for SMBs
As cloud computing evolves and as providers bring more and higher-level services to the market, computing resources stop being so much of a constraint to the development of systems and applications, and become simply building blocks that we can employ. Less constraints means more opportunities, especially for small and medium companies who are more agile and quicker to react to market trends than their bigger competitors.
Bank Finds that Active/Active is Better than the End of the Rainbow
The bank realizes that going active/active is not as simple as moving to a sizzling-hot standby. Several problems must be faced when running an application in a distributed environment. For instance, the applications may need to be modified to correctly handle memory-resident data structures that are not replicated. Another problem is data collisions. A data collision occurs if applications at two nodes modify the same data object within the replication latency of the replication engine.

Cisco’s remedy for connected car security: Treat the car like an enterprise
Cisco Systems and auto components maker Continental believe they have an answer to the security threat facing the vehicle of the future: treat it like an enterprise. Each car should have security and access permissions of a self-contained enterprise network, and every incoming and outgoing communication would be monitored and managed the same way an IT department walls off a corporate network from the outside world.
Data Center I/O Bottlenecks Performance Issues and Impacts
The continued need for accessing more storage capacity results in an alarming trend: the expanding gap between server processing power and available I/O performance of disk storage (Figure-2). This server to I/O performance gap has existed for several decades and continues to widen instead of improving.
