Not technically true. NT meant N10.
One surprising fact about the first Windows NT: NT meant “New Technology,” and NT 3.1 wasn't built just for Windows apps. It was designed with multiple environment subsystems, supporting Win32, POSIX and character-based OS/2 apps on top of the same NT architecture. Windows was basically one personality on top of NT. Pretty wild for 1993.

After programming for 16 years, I finally learned the difference between “function arguments” and “function parameters”. I’ve been using them interchangeably assuming they’re synonyms.

AI Engineering in 2026 is basically 10 AI/DS jobs wearing a hoodie. You’re expected to know: → Python → SQL → ML / Deep Learning → LLMs + Prompt Engineering → RAG → MLOps → Data Engineering → System Design → Cloud → Deployment …and somehow make all of it work together. This is why I think a lot of Data Scientists feel overwhelmed moving into AI. They look at the AI Engineer skill stack and think: “Do I seriously need to learn ALL of this?” No. But you do need to understand how the pieces connect. That’s the big shift: Traditional Data Science was largely: Data → Model → Prediction AI Engineering is increasingly: Data → Models → LLMs → Tools → Agents → APIs → Infrastructure → Product You’re not just building a model anymore. You’re building a system that does work. And this is actually good news for Data Scientists. You already have a huge part of the foundation: Python. SQL. Statistics. Machine Learning. Data. You don’t need to start over. You need to layer AI Engineering on top of what you already know. That’s why the best career move right now is: Data Scientist → AI-Powered Data Scientist → AI Engineer Not abandoning Data Science. Expanding it. Want help? 🚨 Want to learn how to build + ship AI and Data Science projects (that businesses actually want in 2026)? On September 23rd, I am hosting a free workshop to help you get started with AI + DS projects in Python (free). Register here (500 seats): learn.business-science.io/ai…

People who think Office, Teams, or Outlook coming to Linux as native apps are stuck in a pre-@satyanadella idea of Microsoft. This was the memo 10 years ago!! microsoft.com/en-us/windows-…

I have stock in SpaceX and Tesla, not some big pile of cash. As my companies do more and more useful things, their value increases proportionate to their projected usefulness. All shareholders benefit along the way, including most retirement programs.
