To understand whats happening in todays complex software ecosystems, you need comprehensive telemetry data to make it all observable. In fact, observability is essential for shaping how we design smarter, more resilient systems for the future. With so many types of technologies in software stacks around the globe, OpenTelemetry has emerged as the de facto standard for gathering telemetry data.

There are many ways to deploy your microservices, each offering different levels of control, simplicity, and scalability. One approach is using Elastic Beanstalk , a fully managed service that simplifies deployment, scaling, and management. Another option is to deploy manually, giving you full control over the infrastructure but requiring more setup and maintenance.

Managing MySQL through the command line is powerfulbut not always the most user-friendly experience, especially when working with large datasets, building queries, or handling administrative tasks. Thats where MySQL GUIs come in. A graphical user interface (GUI) helps simplify how you interact with your MySQL databases. Whether youre a developer, database administrator, or data analyst, a good GUI can make everyday tasks faster, clearer, and less error-prone.

As I recall our conversation, I told Sam I was intrigued, but with reservations. I explained to him that we could only license our data if they had some mechanism for tracking usage and compensating authors.

CPU cores have become significantly wider over the past decade. Ten years ago, the highest-performance CPUs could decode only up to four instructions simultaneously and execute up to eight instructions. However, top-tier CPUs released in recent years have grown to nearly twice this width. For example, Apple’s M4 processor , released in 2024, can decode 10 instructions simultaneously and execute up to 19 instructions.

TL;DR: Enterprise AI teams are discovering that purely agentic approaches (dynamically chaining LLM calls) dont deliver the reliability needed for production systems. The prompt-and-pray modelwhere business logic lives entirely in promptscreates systems that are unreliable, inefficient, and impossible to maintain at scale. A shift toward structured automation, which separates conversational ability from business logic execution, is needed for enterprise-grade reliability.
