I'm posting this as more of a "fun thought" than anything else.

It's generally considered a fact that Linux, along with many other open-source software projects, are more efficient than their propriety closed-source counterparts, specifically in terms of the code that they execute.

There are numerous reasons for this, but a large contributing factor is that open-source, generally speaking, incentivises developers to write better code.

Currently, in many instances, it can be argued that Linux is often less power-efficient than its closed-source counterparts, such as Windows and OSX. However, the reason for this lies not in the operating system itself, but rather the lack of certain built-in hardware support for Linux. Yes, it's possible to make Linux more power-efficient through configuring things differently, or optimizing certain features of your operating system, but it's not entirely uncommon to see posts from newer Linux laptop users reporting decreased battery life for these reasons.

Taking a step back from this, though, and looking at a hypothetical world where Linux, or possibly other open-source operating systems and software holds the majority market share globally, I find it to be an interesting thought: How much more power efficient would the world be as a whole?

Of course, computing does not account for the majority of electricity and energy consumption, and I'm not claiming that we'd see radical power usage changes across the world, I'm talking specifically in relation to computing. If hardware was built for Linux, and computers came pre-installed with optimizations and fixes targetted at their specific hardware, how much energy would we be saving on each year?

Nanny Cath watching her YouTube videos, or Jonny scrolling through his Instagram feed, would be doing so in a much more energy-efficient manner.

I suppose I'm not really arguing much, just posting as an interesting thought.

I own a pair of speakers which are powered by USB. I've had them plugged into my computer for a long while, but whenever I turned up the volume, I'd hear a high-pitched squealing sound from them which would fluctuate in pitch. For the longest while, I thought this was just an issue with the AUX cable, perhaps something relating to my GPU's coil whine.

Recently, though, I more or less completely rebuilt my PC minus 1 of the hard drives, which I'm still using now. I noticed that the speakers were still squealing even with the new motherboard, PSU and GPU.

A couple posts I found online indicated that the problem was likely due to an under insulated AUX cable receiving interference from EMF waves.

Despite that, for whatever reason, I decided I'd try to plug the speaker's power cable into the USB port on my power outlet. The squealing completely stopped! I'm not sure if there is a difference with the power delivered by computers USB ports vs the outlet (Please do let me know if there is!), but the issue has completely resolved itself.

Not sure if this is really the best place to post this, but I just really wanted to tell someone. I'm quite content!
