This blog post describes a research initiative aimed at eliminating vulnerabilities resulting from memory management problems in C and C++. Memory problems in C and C++ can lead to serious software vulnerabilities including difficulty fixing bugs, performance impediments, program crashes (including null pointer deference and out-of-memory errors), and remote code execution.
This blog post is the second in a series on Agile adoption in regulated settings, such as the Department of Defense, Internal Revenue Service, and Food and Drug Administration.
The adoption of new practices, such as agile or any new practice for that matter, is a task that is best undertaken with both eyes open. There are often disconnects between the adopting organization's current practice and culture and the new practices being adopted. This posting is the second installment in a series on Readiness & Fit Analysis (RFA), which is a model and method for understanding risks when contemplating or embarking on the adoption of new practices, in this case agile methods.
When a system fails, engineers too often focus on the physical components, but pay scant attention to the software. In software-reliant systems ignoring or deemphasizing the importance of software failures can be a recipe for disaster. This blog post is the first in a series on recent developments with the Architecture Analysis Design Language (AADL) standard. Future posts will explore recent tools and projects associated with AADL, which provides formal modeling concepts for the description and analysis of application systems architecture in terms of distinct components and their interactions. As this series will demonstrate, the use of AADL helps alleviate mismatched assumptions between the hardware, software, and their interactions that can lead to system failures.
In 2011, Col. Timothy Hill, director of the Futures Directorate within the Army Intelligence and Security Command, urged industry to take a more open-standards approach to cloud computing. "Interoperability between clouds, as well as the portability of files from one cloud to another, has been a sticking point in general adoption of cloud computing," Hill said during a panel at the AFCEA International 2011 Joint Warfighting Conference. Hill's view has been echoed by many in the cloud computing community, who believe that the absence of interoperability has become a barrier to adoption. This posting reports on recent research exploring the role of standards in cloud computing and offers recommendations for future standardization efforts.
