雷军在今天以小米科技而闻名业界。
但现在可能不太为人所知的是：雷军更是中国老一代的优秀程序员，尤其以他与求伯君作为金山软件元老的经历而广为人知。
我们今天和您一起欣赏一份雷军在加入金山前（自己首次创业期间），在1992年以“黄玫瑰小组”一员的身份写的汇编代码。领略当时的技术手段和老一代程序员的程序人生。
参阅：雷军的首次创业
受《硅谷之火》中创业故事影响，在大学四年级的时候，雷军开始和同学王全国、李儒雄等人创办三色公
司。当时的产品是一种仿制金山汉卡，可是随后出现一家规模比他们更大的公司，把他们的产品盗版了，而且这家公司可以把同类的产品做得量更大，价格也更低。三色公司度日维艰，不要说公司运营，即使他们生活上也面临着等无米下锅的局面。半年以后，三色公司决定解散。清点公司资产时，雷军和王全国分到了一台286电脑和打印机，李儒雄分到了一台386电脑。
“在三色公司工作期间，雷军与王全国合作编写了雷军的第一个正式作品BITLOCK加密软件并组建了黄玫瑰小组；除此还用PASCAL编写免疫90，此产品获得了湖北省大学生科技成果一等奖。”
