I bought it at Jim Joyce 's bookshop that was set up in one of the hotel suites possibly one of the first attempts to sell books at a Usenix conference .

我是在JimJoyce的书店买的这本书，这个书店开在酒店的一个套间 里， 他可能也是第一个尝试在 Usenix大会上卖书的人。

The best way to contact publishers is to go to a technical conference ( Usenix Interop etc. ) and go to their booths and talk to them .

联系出版公司的最佳途径是参加技术会议（ Usenix、Interop，等等），到他们的展台 前当面谈。
