https://ruby-china.org/heimirror en-us <p>我要解决的问题主要是打字好多年了手指痛，现在每天上班手指都隐隐作痛，尤其是下班的时候感觉明显 目前用的键盘是 MAC PRO 的键盘，感觉很硬，一天下来手指痛到不行 这两天也在网络上包括 ruby-china 社区看有关键盘的帖子 综合下来主要在红轴和茶轴之前徘徊，因为据说这两个轴打起来比较轻 品牌的话也还不知道选哪一个，不过 hhkb 是超预算的</p> <p>前几天因为看到网上说小米的机械键盘很轻，所以买了一个小米的机械键盘， 买来后试用了一下除了 shift/回车/退格键之前其他键用着还是挺舒服的，不过那几个键用着太垮了 所以退掉了，跑来社区求大家推荐</p> <p>总结下来就两个问题： 1、红轴 or 茶轴 2、品牌</p> <p>PS：强烈建议预计未来很多年要敲代码的朋友换一个好键盘和鼠标（如果你也用鼠标的话），不然等到手指痛就真的晚了</p> heimirror Sat, 04 Mar 2017 22:41:51 +0800 https://ruby-china.org/topics/32443 https://ruby-china.org/topics/32443 <p>这两天在 ubuntu14.04.2

男就是木讷、没情趣？近日，汉口的余女士却记录下生活点滴，发帖赞扬自己的 IT 界老公，短短数日吸引近三万网友围观，不少单身女网友更高呼“求介绍”。于是，余女士还创建了 IT 男交友 QQ 群，以推荐更多 IT 行业的单身朋友。</p> <p> 余女士今年 29 岁，从事教育培训工作。2009 年底，她与丈夫周先生在一次同学聚会上相识。起初，对“IT 男”有偏见的余女士对周先生并无好感，觉得他肯定很无趣。但很快，她就在聊天中发现，周先生性格朴实，热爱生活，也有自己独特的幽默感。2011 年 12 月，两人喜结良缘。</p> <p> 顺从老婆，每个月工资准时上交；生活节俭，一件 30 元钱的短袖穿了四年；准时回家，绝不会让老婆独守空闺……周先生总是让老婆特别安心。而且，他每年都会带余女士旅游几次，出发前他会规划路线写好攻略，余女士什么都不用操心。</p> <p> 上个月，余女士将这些生活点滴写成帖子《找个 IT 男做老公吧》发布在论坛上，目前已有近三万网友围观。不少女网友留言表示羡慕，其中更有人私信余女士，请她帮忙介绍 IT 界朋友。余女士干脆创建一个交友 QQ 群，为大家搭建交流的平台，目前已有百余人加入。“希望更多人和我一样，打破对 IT 男的固有印象，发现他们的优点。”余女士说。</p> heimirror Mon, 14 Oct 2013 11:45:50 +0800 https://ruby-china.org/topics/14726 https://ruby-china.org/topics/14726 <p>RT
