If your #Microsoft365 subscription is about to end: First, disable auto-renewal and wait until it has finished. Then, continue it for just one month. After that, you will see a banner allowing you to buy one year with a 25% discount. For me, this cost €113 for 13 months of the family plan.

📱 This actually popped up two weeks ago on my #Pixel phone but didn’t have time to post— #Android warning me about an #AirTag riding along. Kinda creepy, but also cool that #Google catches this stuff now.
Screenshot of a Google Play Services notification warning about an unknown Apple AirTag traveling with the user. The alert states that the tracker’s owner can see its location, highlighting a potential privacy and safety concern. Screenshot showing an Apple AirTag alert with details: first detected on 10 Nov at 17:35, warning that the tracker’s owner can see its location. Instructions are given to locate and disable the tracker if it’s not yours.

Didn't know that #GitHubCopilot has a CLI version. At work, I mostly use the #AmazonQ #VSCode extension because of the company licence. It's much worse than Copilot, but they have a CLI version for #Linux which is pretty good, especially for fixing problems with OS. github.com/features/cop...

GitHub Copilot CLI reads, writes, and runs code where you work. Code faster, smarter, together.

I'm mostly a UI-first dev—only touch the console when absolutely necessary. But for installing and updating apps on #Windows11, I've fully switched to #winget. CLI wins here: faster, cleaner, and way more convenient than manual installs.
#Windows #DevLife #CLIconvert #ProductivityTools
Terminal window showing the output of the winget upgrade command on Windows 11. A table lists installed applications with columns for Name, Id, Version, Available (update version), and Source. Apps like Git, Microsoft Edge, Python, Visual Studio, Discord, and Microsoft Teams are shown with newer versions available via the winget source.
