Extension August 26, 2025

Launching NtraBoost - Microsoft Entra Extension

For the past few weeks, I've been working on an extension designed to simplify and speed up many actions in the Microsoft Entra ID portal.

🔔 Want to be notified when it launches? I've just set up ntraboost.com so you can get an alert as soon as Ntra Boost goes live (no typo here - I preferred not to call it "Entra Boost" since "Entra" is a Microsoft trademark).

Workbook July 7, 2025

📢 New Summer Series: The PowerShell Summer Workbook

📚 Inspired by traditional summer revision workbooks, this series is designed to help you deepen and master the subtleties of the PowerShell scripting language.

👨‍💻 At a time when anyone can generate a PowerShell script with a single prompt to their favorite AI, I think it's important to revisit certain points that transform a simple 3-hour script into a (relatively) fast and robust script.

🔺 For the past few months, I've seen an explosion of PowerShell projects (which is great). Everyone can be a beginner or not know best practices: that's normal, but it's important to learn and apply them.

🔺 Like all my other summer workbooks, this is not a course starting from scratch on PowerShell. However, even if you're a PowerShell beginner, there will definitely be things that will be useful to you.

🔺 The goal of PowerShell can be seen as automation and standardization of work, we also talk about industrialization.

🔺 Publication twice a week: Monday and Thursday.

🧠 So, ready to level up your PowerShell skills?
