Given the increasing popularity of ChatGPT in solving questions of humankind, I decided to take a better look at the current state of AI. At the same time that I see database engineers relying on the tool, sites such as StackOverflow are banning ChatGPT. As the question comes from time to time, is my profession at risk of being extinct due to AI? As my mentor said when I started working in the tech area, the answer is: it depends.

Many organizations are adopting a DevSecOps approach to software delivery with the goal of accelerating release validation and ensuring frictionless, secure software delivery. But without intelligent automation, they’re running into siloed processes and reduced efficiency. Since the Log4Shell vulnerability of 2021, modern multicloud complexity and data proliferation have steadily increased, providing more opportunities for security vulnerabilities to stealthily enter the software delivery

The main purpose of this article and use case is to scrape AWS CloudWatch metrics into the Prometheus time series and to visualize the metrics data in Grafana. Prometheus and Grafana are the most powerful, robust open-source tools for monitoring, collecting, visualizing, and performance metrics of the deployed applications in production. These tools give greater visibility other than collecting the metrics also, where we can set up critical alerts, live views, and custom dashboards.

CPU isolation and efficient system management are critical for any application which requires low-latency and high-performance computing. These measures are especially important for high-frequency trading systems, where split-second decisions on buying and selling stocks must be made. To achieve this level of performance, such systems require dedicated CPU cores that are free from interruptions by other processes, together with wider system tuning.

Eighteen months ago, I wrote that there is a good case to be made that the tech cycle is more economically significant than the credit cycle. By way of example, customer-facing tech and corporate collaboration technology contributed far more to robust S&P 500 earnings during the pandemic than the Fed’s bond buying and money supply expansion. Having access to capital is great; it doesn’t do a bit of good unless it can be productively channeled.

Flutter is a free and open-source SDK that simplifies creating mobile apps for several platforms. You can quickly create natively generated apps for both iOS and Android without having to rewrite your code. A single set of codes can serve both systems. The benefits of using Flutter for mobile app development have been dis cussed in this post. Over 2 million developers have used the Flutter toolkit since its introduction in 2018, as Tim Sneath, Flutter’s product manager, reported last year.
