CircleCI is an opinionated SaaS CI/CD platform that works hand in glove with GitHub Enterprise Cloud.

I just released a new Pluralsight course, Getting Started with CircleCI, focused on practical pipelines and how CircleCI thinks about CI/CD.

Check it out!

Microsoft has 3 paths for building agents and most orgs pick wrong:

πŸ”Ή M365 Copilot agents = glorified custom GPTs
πŸ”Ή Copilot Studio = where real power lives
πŸ”Ή Azure Foundry = nuclear option

They're layers, not competitors. Start low-code.

Case studies on Microsoft cert exams stress everyone out β€” until you have a system.

My 4-step strategy:

β†’ Skim for theme (90 sec max)
β†’ Find the callback hint in each question
β†’ Targeted tab search
β†’ Match and answer, keep moving

Work smarter, not harder.

GitHub Copilot Models Explained
YouTube video by Tim Warner GitHub Copilot Models Explained

GitHub Copilot has multiple AI models now - GPT, Claude, Gemini - but most devs don't know that Claude Opus costs 10x more per prompt than the default models.

Just dropped a full breakdown of model selection & premium request pricing.

GitHub Copilot Workspace Indexing: @workspace vs #codebase Explained
YouTube video by Tim Warner GitHub Copilot Workspace Indexing: @workspace vs #codebase Explained

GitHub Copilot has TWO ways to understand your code:

#codebase β†’ context variable (sculpts what it sees)
@workspace β†’ chat participant (adds LLM reasoning)

Most devs use them interchangeably. They're not.

How to Use GitHub Copilot Chat Modes in VS Code (MCP Management)
YouTube video by Tim Warner How to Use GitHub Copilot Chat Modes in VS Code (MCP Management)

Your Copilot agent hitting "degraded state" because you loaded 15 MCP servers at once?

Chat modes = surgical tool selection. Documentation MCPs for writing, GitHub tools for PRs, clean context for each.
