I started digitizing my Blu-ray collection (again) for a Plex server and I am shocked — one simple tweak and my old drive can magically handle 4K UHD discs I don't own a Blu-ray drive for my PC that says it can read 4K discs. But, thanks to the Internet, it seems I do now.

In the process of digitizing my Blu-ray collection, I presumed I'd need to upgrade my hardware for the 4K UHD discs.
Turns out that wasn't the case.

With one simple tweak, my old drive can magically handle them on Windows.

Who really pays for tariffs?

Most .NET devs ignore this.

But it makes debugging 10x easier.

Instead of {Namespace.ObjectName}, you can show:

The trick?

How To: Resolve Poor Performance on Raspberry Pi 4 When Running Visual Studio Code Occasionally, I will hack around on a Raspberry Pi 4 with my son.  Recently, we had been creating a fun home motion detection home security system. We had been using Thonny as it shipped with the Pi installation and was running smoothly. The simple interface was good for my son. I installed Visual Studio Code.  It was unusable. The performance was terrible. The slightest click or cursor movement took ages. The PI has 8GB of RAM so should be fine. After a little digging, it turns out, you need to disable hardware acceleration. ~ Visual Studio Code To do this, press F1 in VS Code, type runtime:   Select: Preferences, Configure Runtime Arguments The file will load, you need to set this to the following: That’s it. Visual Studio Code is now useable in the Pi. In a future post, I will share how we built an AI home security system using .NET, Semantic Kernel, Telegram, and Raspberry Pi. Stay tuned. ~

How Much Energy Does AI Use? The People Who Know Aren’t Saying A growing body of research attempts to put a number on energy use and AI—even as the companies behind the most popular models keep their carbon emissions a secret.

AI this, AI that, what about how much energy AI actually uses?

“It blows my mind that you can buy a car and know how many miles per gallon it consumes, yet we use all these AI tools every day and we have absolutely no efficiency metrics, emissions factors, nothing." From the experts:

The image features three white icons on a gradient background transitioning from blue on the left to green on the right. The first icon, located on the left, depicts a network or molecular structure with interconnected circles. The middle icon shows a laptop with an attached mouse. The third icon, on the right, represents a hierarchical organizational chart with connected squares.

Can You Build Agent2Agent Communication on MCP? Yes! - Microsoft for Developers MCP has evolved significantly beyond its original goal of “providing context to LLMs.” With recent enhancements including resumable streams, elicitation, sampling, and notifications (progress and resources), MCP now provides a robust foundation for building complex agent-to-agent communication systems.
