Apple Consumer Survey: 4-inch iPhone and Apple Watch, March 2016
In March 2016, Apple is expected to announce a new model of iPhone that goes back to the smaller 4-inch screen of previous generations. Many current iPhone users are less than excited.
In a recent survey, 78% said they would not consider switching to this new 4-inch iPhone.
In addition to the smaller screen size, the new device will also miss out on the much-hyped 3D Touch.
For a company that’s so strongly identified with innovation, consumers may feel let down by a device that offers no new capabilities, but still comes with a hefty price tag.

The summary provides the following key points in 3 sentences:
iPhone is King - The analysis found that despite Android dominance in the general population, students used Apple phones and tablets at a 7-1 ratio, far outpacing Android devices, which has implications for how development resources should be allocated. Performance is King - The foremost driver of ratings and feedback was performance, as users placed responsibility on the publisher for any issues even if due to external configuration factors, and functionality was less important if it impacted performance.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
