Linux kernel 6.12 is one of the most significant releases of the year, delivering a feature nearly 20 years in the making: true real-time computing.

Realtime doesn't necessarily mean low latency, it means consistent latency.

This is such a critical distinction which can be counter-intuitive. In this case, their game may run slower, they just won't get lags resulting from local resource contention. And even that statement has caveats.

One of the biggest difference between self-taught developers and ones with CS degrees is that the ones with degrees usually understand a lot of important theory, such as O(1) means constant time, not necessarily fast time.

It doesn't help that its not well named, realtime makes it sound fast.

One of the few things I remembered from my degree was the realtime programming course, because we got to program a model train set in Ada, on a 286(?), running on floppies. This was in ~2015, so ancient hardware even then, and it was slow, but it was "realtime".

Interestingly, my compsci degree never covered O notation, so that I've had to pick up along the way :/
