Airborne data collection solution to solve the challenges of managing assets and equipment across organizations, across large geographical areas or industrial spaces, while improving safety, productivity and data accuracy. While airborne, the drone is collecting a wide range of data from ground based sensors, on-board sensors, and can also include variety of video imaging. This data provides location based information on equipment, materials, and assets located in the monitored space. Cloud data platform securely manages and analyzes the data and provides organizations with a high quality of item and location data.

How to evaluate open-source projects security can reduce the risks In the last year, we have seen at least two important supply-chain attacks, on Solarwind and Codecov products, and a new technique, named Dependency Confusion, to hack software dependencies. Protecting software from supply-chain attacks has become a priority both for companies and open-source projects. So, how can developers and engineers evaluate the security health of an open-source project? The answer is evaluating the right metrics for every dependency.

SensorBench is a benchmark suite for wireless sensor networks. The design of wireless sensor network systems sits within a multi-dimensional design space, where it can be difficult to understand the implications of specific decisions and to identify optimal solutions. SensorBench enables the systematic analysis and comparison of different techniques and platforms, enabling both development and user communities to make well informed choices. The benchmark identifies key variables and performance metrics, and specifies experiments that explore how different types of task perform under different metrics for the controlled variables. The benchmark is demonstrated by its application on representative platforms. Full details of the benchmark are available from http://dl.acm.org/citation.cfm?id=2618252 (DOI: 10.1145/2618243.2618252)

In this episode, Darren talks about the history of applications and how recent changes, primarily due to the onslaught of data from the Internet of Things, is affecting data-centric architectures. The infrastructure is ready, but we don’t yet have a suitable way to manage all our data. There are three elements that need to change to facilitate this process: people (organization), process (operation), and architecture (technology). Darren focuses on the architecture where data and compute are spread over thousands of edge devices and across public and private clouds. https://www.embracingdigital.com/2020/01/episode-11-history-of-data-centric.html

The Kubernetes community has made major strides in supporting stateful workloads, but it’s just the beginning of how Kubernetes could be leveraged as a standard to revolutionize data: to make data declarative, just like Kubernetes. The Data on Kubernetes Community (DoKC) is an openly governed community of practitioners who share an interest in making this a reality. In this talk, Logan will provide an update on the DoK Community and share results from the first-ever Data on Kubernetes survey (https://dok.community/dokc-2021-report/). This talk was given by Melissa Logan as part of DoK Day at KubeCon NA 2021, watch it below. You can access the other talks here (https://youtube.com/playlist?list=PLHgdNuGxrJt2twht-2suDZaV2zlptDJIf).

Whether you’re an enterprise migrating to cloud native or born in the cloud, most of today’s APM and Observability tools don’t support how your engineers and DevOps teams need to develop, deploy, and support their software. Observability needs to shift left and reflect the modern way companies organize their development teams and their vital interdependencies. Chronosphere is the only vendor addressing the unique requirements for observability in a cloud native world. Join this webinar to learn: - What cloud native observability is and how it is different from the promises made by traditional cloud APM and observability vendors - How to use cloud native observability to do more “Dev” and less “Ops” so you can dramatically improve developer and engineer workflows and productivity - How to make on-call shifts less stressful so your engineers aren’t getting burned out

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.
