CPUfreq is the part of the Linux kernel that changes your CPU's frequency to save power or increases it to make your system run faster. Obviously the settings you use there are essential for you performance and battery consumption. I read an extensive article by IBM some time ago analysing the different Linux cpu frequency governors. It makes lots of fancy tests and has great diagrams etc. What it boils down to is that these are the perfect setttings for low power at high performance in Linux.

This is the sort of article that really pees me off. This time, it's Android partisanship. More often, it's $SOME_SPECIFIC_DISTRO partisanship. The article is about how to control cpufreqd, which is information applicable to any box on which cpufreqd is being used. Why bring up Android specifically, when at the bottom of the article $AUTHOR even says it's applicable to any box on which cpufreqd is being used.

In Hollywood, this is called product placement. Android is irrelevant to this article, except as an example of cpufreqd mgmt.

Frankly, I liken this to Google Astroturfing in this case.

Explain your ideas/tech, then perhaps mention example implementations, WITHOUT astroturfing your employer/distro/yada yada first.
You know, I agree with you on this one.

This is applicable to just about any distro you care to name. Targetting it at android seems a tad ... pedantic I think is the word I'm looking for.
For me, this sort of thing just plays up all the, "Why so many distros?!?" shiat. The tech is what's important. Learn the underlying tech, and you'll have little trouble applying it anywhere it's applicable.

We don't need partisanship. It's divisive.
Well, on the other hand, I already knew you could do this in "proper" Linux distributions, but it hadn't occurred to me that it was also accessible in Android, which tends to lack a lot of "standard" Linux capabilities (X11, real root shell access without having to fight against the installed OS, etc).
