前些日子通勤路增加到了近60公里,每天骑行近3小时着实让自己感觉吃不消。趁着天热经常下雨的这段日子,动起了助力改装的念头。想着通过改装,让自己省些劲,尽量把时间缩回到每天2小时多点的程度。

怎么个改法自己琢磨了一下,目标确定为助力改装,首先需要保证车子仍然能骑,不能加电后出现踩空情况,也不能出现加电机后骑行阻力增加的情况。车子不能改成纯电动,需得是电动助力,主要需要用到的场合是起步和上坡。简单总结就是需要起步和上坡时帮出力,平路下坡时还不能拖后腿。这样把起步和爬坡费的劲和时间都补上的话,目的就能够达到了。安全性上要求脚不蹬轮不转,停车时踩脚踏也不加电,像正常骑行那样动力自主。

From time to time, you may come to a situation of trying to backup the entire system. While searching for an easiest way to do this, I found an easiest solution in Arch Linux wiki. I never thought that it was going to be that much simple. I copied my entire root (/) tree incrementally with Rsync using a single line command everytime I want to backup my system. While there there so many tools to backup your systems, I find this method super easy and convenient, at least to me. Also, this method is way better than disk cloning with dd command. Because It doesn’t matter if your hard drive is different size, or use different filesystem. This method will work on almost all Linux systems that have rsync installed.
