MLOps and AIOps both sit at the union of DevOps and AI. They may sound like the same thing, but they represent completely different ideas.
Here’s a quick explanation.

Leila Gharani shows us how to use Microsoft Forms you can collect data from different people via fillable forms that you can control from Excel.
With Microsoft Forms you can easily create surveys, quizzes and polls. You can export the data to Excel to analyze and share the results with your audience. No programming is necessary, no VBA, no add-ons. Just a Microsoft 365 account (free or paid).
We’ll cover how you can use Microsoft forms to add dropdowns, multiple choice, calendar date selection, number checks, net promoter score, and even star ratings.

freeCodeCamp.org has made the Practical Deep Learning for Coders is a course from fast.ai available .
This course was created to make deep learning accessible to as many people as possible. The only prerequisite for this course is that you know how to code (a year of experience is enough), preferably in Python, and that you have at least followed a high school math course.
This course was developed by Jeremy Howard and Sylvain Gugger. Jeremy has been using and teaching machine learning for around 30 years. He is the former president of Kaggle, the world’s largest machine learning community. Sylvain Gugger is a researcher who has written 10 math textbooks.
Jeff Geerling puts the Compute Module 4 through its paces and compares it to the Raspberry Pi 4 and Compute Module 3+, highlighting some great new features like a PCI Express 1x slot on the IO board and NVMe support.

Einstein’s special theory of relativity combines space and time into one dynamic, unified entity – spacetime.
But if time is connected to space, could the universe be anything but deterministic? And does that mean that the future is predestined
PBS Space Time explores what this means.
Linked servers enable the SQL Server and Azure SQL Database Managed Instance to read data from remote data sources and execute commands against the remote database servers.
In this video, Anna Thomas and Colin Murphy go over configuring linked servers in Azure SQL Database Managed Instance.
At the end, Anna briefly mentions creating a linked server to the readable secondary replica for read-heavy workloads.
It’s Tuesday and you know what that means: High Impact Tuesday!
