30 Lines of Code Could Cut Data Center Power Use by 30%

Well, if it works, they'll apply it. Saving 30% on your electricity bill would probably save a lot of money.

This is the actual change if you're curious: https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=80b6f094756f

And the paper: https://dl.acm.org/doi/abs/10.1145/3626780

That's way more than 30 lines or code and also their "We didn’t add anything." claim seems to be nonsense.
- Most of what you're looking at there is tests and comments, the actual additional code is minimal (I'm not gonna try and count the lines on my phone)

And yet we write giant web applications in frameworks like django and ExpressJS

Honestly I'm surprised Golang hasn't taken off more.

Because programmer hourly pay is way higher than server hourly cost. Abundant nodejs developers can pump shitty code faster, therefore delivering features faster. That’s all shareholders care about.
- See, in not so sure about that. Go has a lot of issues, things it doesn't do well, but one thing it is good at is being simple. I would argue that it's certainly not more complex than JavaScript, and in many cases, is easier simply because there are fewer "gotcha" edge cases that impact new developers. And Go is slowly eliminating those gotchas (such as the loop variable shadowing issue).
  
  Your argument holds for Rust v JS; the Rust learning curve is higher, and you have to understand many more technical computing topics to write good code. But I don't think the same holds for Go. Anyone capable of learning JS is capable of learning Go, in nearly the same time.
  
  Maybe you're saying that there's a veritable legion of JS script monkeys, and so it's cheaper because of supply and demand. I'd agree with that. JS programming skills are certainly far more fungible between companies, which encourages new developers to choose it. I just don't think it has as much to do with language complexity or difficulty.
- Almost like a system where the only consideration is maximizing profit margins isn't ideal. ://
  
  If I'm ever in politics I'll prioritize cooperatives. Nothing wrong with profit, but it doesn't have to be the only thing a corporation cares about.

A typical data center rack holds about 40 servers, each with at least two networking interfaces. According to Boote, the Ethernet interfaces of a single rack draw 160 watts in total.

“Reducing the power draw of a data center, which may have hundreds or thousands of racks, would be akin to an energy savings of switching a building from incandescent to more energy efficient LED lighting and be well worth the investment,” he told LinuxInsider.

According to Boote, this optimization fixes a part of the kernel written when lower-speed Ethernet interfaces drew a fraction of today’s electrical needs. The networking stack design did not account for the growing power budget required by modern networking interfaces.

“By changing the priority of how the computers schedule tasks during high bandwidth events, a computer can better deal with networking traffic and prioritize energy expenditure in a way that makes sense for modern hardware and architectures,” he reasoned.

Are one of those lines exec "shutdown -p now" ?

[ $((RANDOM % 100 + 1)) -le 30 ] && shutdown -p now

He explained that IRQ suspension enhances network performance while maintaining low latency during low-traffic conditions by reducing unnecessary CPU interruptions during high-traffic periods.

Am I overtired or is this nonsense?

I think, you have to read it like this:

He explained that IRQ suspension enhances network performance ... by reducing unnecessary CPU interruptions during high-traffic periods. It also maintains low latency during low-traffic conditions.
- See, that makes sense. You're probably right. They didn't paren their parenthetical.
He explained that IRQ suspension enhances network performance, while maintaining low latency during low-traffic conditions. It accomplishes this by reducing unnecessary CPU interruptions during high-traffic periods.

Maybe that makes more sense? The original was definitely a run-on sentence, and needed some punctuation.
