NewsWhat are Agents & How they Work? #agent #llm #genai
AI agents combine a large language model for reasoning, external digital tools for executing actions, and memory for tracking context to complete complex tasks autonomously. This architecture allows the system to continuously loop through planning, executing, and adjusting steps until a defined goal, such as organizing a chaotic folder of files, is fully achieved.
NewsForward Deployed Engineers (FDE) vs Data Engineers (DE) #fde #dataengineering
Forward deployed engineers embed with business executives to build custom AI models that solve specific problems like customer churn directly within legacy systems, contrasting with traditional data engineers who maintain data infrastructure and pipelines. They command premium salaries because they combine production-level coding skills with management consulting expertise to implement solutions without disruptive migrations.
TutorialsDatabricks All Purpose vs Serverless Computes #databricks #databrickstutorial
Databricks all-purpose compute provides traditional persistent clusters with manual configuration and continuous uptime costs. Serverless compute offers fully managed infrastructure that boots in seconds, scales dynamically, and bills only for active execution time.

This video teaches how to build AI agents using the LangChain framework in Python. It demonstrates initializing a model, registering Python functions as structured tools, and creating both single agents and supervisor-sub-agent architectures.
NewsSpark vs SDP, What the difference? #spark #pyspark #dlt
Traditional Apache Spark requires developers to manually write complex procedural code for processing steps, state management, and checkpoints. Spark declarative pipelines allow users to define the desired final data state in SQL or Python while the engine automatically handles execution order, dependencies, and incremental processing.
NewsWhat is RAG and How it Works? #genai #llm #generativeai #coding
RAG solves AI hallucination by chunking large private documents into searchable segments and retrieving relevant context for each user query. The system then augments the user's question with the retrieved context before sending it to the AI, enabling factually accurate answers without guessing.
