2016 DTrace conference 小结

DTrace conference举办周期同奥运会一样。今年的conference在上个月举行了,议程如下:

11:15   Graeme - Distributed DTrace
        Max - (Useful!) DTrace intro, including DTrace production golf?

12:30   George - D language improvements
        Matt - D syntactic sugar
        Robert - CTF everywhere!

1:30    Eric - DTracing apps
        JoshC - DTrace json() subroutine
        Dan - Dynamic asserts

2:30    James - DTrace and Go
        Dave - DTrace and Postgres
        George - DTrace performance improvements with always-on instrumentation
        Gordon - DTrace ustack() performance improvements

3:30    Bryan - DTrace in the zone
        Ben and Alex - DTrace vulns
        George and Mark - Implementing (or not) fds[] in FreeBSD

5:00    George - OpenDTrace

这次conference似乎不及4年前那次正式:没有T恤,也没有参会视频,只能从社交网络上找到一些零散图片和演讲材料。个人感觉DTrace好像有些没落,而其关注者看起来也并没有什么增长。原因可能是由于Linux正在吞噬服务器大部分市场,导致illumos/FreeBSD这些自带DTrace系统所占的份额越来越少。虽然越来越多的人开始使用Mac OS X,可是会有几个人在Mac OS X上使用DTrace呢?不过不管怎么说,这次conference还是有一些有趣的议题,像DTrace and Go。如果有兴趣,不妨找相关材料看一下,兴许能让你眼前一亮。
