Automatic CPU speed & power optimizer for Linux based on active monitoring of laptop's battery state, CPU usage, CPU temperature and system load. Ultimately allowing you to improve battery life without making any compromises.

One of the problems with Linux today on laptops is that CPU will run in unoptimized manner which will negatively reflect on battery life. For example, CPU will run using "performance" governor with turbo boost enabled regardless if it's plugged in to power or not.

Issue can be mitigated by using tools like indicator-cpufreq or cpufreq, but these still require manual action from your side which can be daunting and cumbersome.

Using tools like TLP can help in this situation with extending battery life but it also might come with its own set of problems, like losing turbo boost. With that said, I needed a simple tool which would automatically make "cpufreq" related changes, save battery like TLP, but let Linux kernel do most of the heavy lifting. That's how auto-cpufreq was born.

Please note: auto-cpufreq aims to replace TLP in terms of functionality and after you install auto-cpufreq it's recommended to remove TLP. If both are used for same functionality, i.e: to set CPU frequencies it'll lead to unwanted results like overheating. Hence, only use both tools in tandem if you know what you're doing.

Working from the assumption that one's well being is directly related to the well being of everyone close to them, supporting oneself is a side effect of supporting those around you. Information about gift economies, altruism, sympathy, compassion, decentralization and ad-hoc organization as health rather than as threat, and a definition of wealth which seems opposed to the traditional notion of wealth-as-money-and-exertable-power.
