How do I see high-precision query times in mysql command line?

阅读更多关于 How do I see high-precision query times in mysql command line?

问题 I'm working through some optimization work, and I've noticed that in some mysql dumps people post in articles and questions (which I cannot find again now that I'm actually looking), there are high-precision execution times (0.05985215 sec instead of 0.06 sec). How can I see these more precise times for my queries on the command line? EDIT Example of this is: +----------+ | COUNT(*) | +----------+ | 11596 | +----------+ 1 row in set (0.05894344 sec) Using profiling gets me part of the way

阅读更多关于 How to redirect from Audio Output to Mic Input using PulseAudio?

I'm working on a mobile app for Maemo/MeeGo and Maemo uses PulseAudio. I want to play a mp3 to caller (and cancel the mic when doing it, and not to listen caller, everything should be done on background), to do this, I have to redirect Audio Output from a certain (if not possible, all) app, fake it as a Input and make Phone app use it.
