编者：(美国)贝里(Lynn)

Lynn，一位困在技术撰稿人身体里的小说家。当她发现技术书籍可以带来实际收入后，终于慢慢地学着接受并享受这方面的工作。

重返校园取得计算机科学硕士学位后，她为NRL和LNAL工作。然后她发现了Flash的存在，并写出她的第一本畅销书。

Lynn选择移居硅谷的时机实在不太好，没过多久网络泡沫就发生了。接下来的几年，她在Yahoo!工作，同时也写了几本书并培训课程。最后她决定转到创意写作行业，因而搬到纽约，取得创意写作的MFA学位。

对着满屋子的教授和同学，她的HeadFirst风格的论文获得了极高的评价，她拿到了学位，也完成了《深入浅出SQL》，等不及要投入下一本书的创作中去。

Lynn喜欢旅游、烹饪、为完全不认识的人编织详细的背景故事。对了，她还有点小害羞。
