在Arch Linux下愉悦地截图

爱不起的Apple Music
十月初开的Apple Music试用。。。 那个时候网易的流量包月还在,还是投向了Apple的怀抱。。。 结果半个月下来,直观感受就是速度慢和曲库烂。。。
给Dell Tower 7910装系统
还是第一次跟工作站装系统,各种谨慎各种小心各种不敢瞎动手。。。 工作站自带的是Ubuntu 12.04 LTS,我一装nvidia-current就挂,不过这个挂的合情合理,然后发现重启的时候进不去BIOS了,一进去只有个什么LSI配置,F2按了,Enter也按了,DEL也按了,都没有反应,后来打电话问DELL客服,告诉我试一试F12,结果一试还真是。。。囧rz。。。
