Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: A minor modification to the Linux kernel code can reduce data center energy consumption by 30-45%, offering a simple solution to the massive power demands of digital infrastructure.
📈 One key stat: Modifying just 30 lines of code in the Linux kernel can cut data center energy use by up to 45%, potentially transforming the environmental impact of the digital backbone that powers our online world.
💬 One key quote: “By modifying just 30 lines of code within the Linux kernel’s protocol stack, energy consumption could be reduced by 30 to 45 percent.“
1️⃣ The big picture: Researchers from the University of Waterloo have discovered that a simple coding modification to the Linux kernel can dramatically reduce data center energy consumption by 30-45%. Data centers form the backbone of our digital world, supporting everything from social media to online banking, but they consume enormous amounts of energy. The modification works by reorganizing operations within the Linux network protocol stack to improve efficiency and reduce unnecessary processor interruptions. This breakthrough is particularly significant since Linux is the operating system of choice for most global data centers.
2️⃣ Why is this good news: This energy-saving solution requires minimal effort to implement as it involves changing just 30 lines of code. The modification has already been incorporated into Linux kernel version 6.13, making it immediately available to data centers worldwide. The open-source nature of Linux ensures that these improvements can be quickly adopted globally without proprietary restrictions. Beyond immediate energy savings, this breakthrough demonstrates how software optimization can significantly reduce environmental impact without requiring new hardware or infrastructure. If widely adopted, this solution could substantially decrease the carbon footprint of the digital economy.
3️⃣ What’s next: Data center operators can implement this energy-saving modification by upgrading to Linux kernel version 6.13 or later. Companies will likely monitor their specific energy savings and performance metrics after implementation. This breakthrough may inspire further research into additional software optimizations that could yield even greater energy efficiency in digital infrastructure.
