[团购电子书] The Art of PostgreSQL 十五人豪华团

话说这两天 The Art of PostgreSQL 黑五打对折，最豪华的 Enterprise Edition 也只要 $114 ，如果 15 个人拼的话每个人只需要出 $7.6 ，四舍五入约等于不要钱好吗！顺便我解释一下为什么是 15 人团：因为 Enterprise Edition 附带的 sharing license 允许我 "Share the book and the docker instance with up to 15 people in your enterprise"

官网链接如下 https://theartofpostgresql.com/

有意向一起拼团的同学可以加我的微信，我们拉个群商量一下怎么支付，比如是直接走微信群收款还是怎么转账给我。另外我不太想直接公布自己的微信号，想必大家也不希望把自己的联系方式随随便便放到公网上，但这种小事自然难不倒身为程序员的我们嘿嘿嘿（本来想留邮箱的，但感觉那种异步交流方式协调起来会很麻烦）

your_wechat_id_here

你可以执行 echo "your_wechat_id_here" | openssl rsautl -encrypt -pubin -inkey ~/.ssh/id_taop.pub.pem -ssl | xxd 之后用 hexdump 的形式把自己微信号的密文发在回复里，我用私钥解密之后就会来加你好友，然后拉你进拼团群；但如果你嫌麻烦，或者完全不介意直接发微信号，那么直接评论明文也完全没有问题。

顺便楼主在美国中部时区，而且最近要期末考了（苦逼学生党啊啊啊），所以回消息可能不是很及时，请见谅！
