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。
