Now, depending on how stressed those CPUs are, Tux will feel healthy or not.\nSee, `dmesg` for more information.\n\n## Awesome! Let's run it in production ...\n\n*... to monitor our servers!\"*\n\nYeah! Great idea! Just, do not tell anyone ...\n\n![don't do it](https://media.giphy.com/media/SEp6Zq6ZkzUNW/giphy.gif)\n\n## I'm a sadist and want to hear Tux suffering ...\n\nWell ... okay. Install **[cpuburn](https://packages.debian.org/jessie/cpuburn)** and let'em burn! :fire:\n\n## So, what's next?\n\n- [ ] Implement as audio device\n- [ ] Improve sound samples\n- [ ] Cleanup code smells\n- [ ] A debian package would be awesome\n- [ ] Generate sound waves instead of having hardcoded data\n- [ ] Automated tests?!\n\n***\n\n*\u003cp align=\"center\"\u003eThis project is published under [MIT](LICENSE).\u003cbr\u003eA [Timo Furrer](https://tuxtimo.me) project.\u003cbr\u003e- :tada: -\u003c/p\u003e*\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftimofurrer%2Fdevheart","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftimofurrer%2Fdevheart","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftimofurrer%2Fdevheart/lists"}
