Dave and Gunnar #55: Mike Guerette loves developers.

The Dave and Gunnar Show is run by two great guys and Red Hatters who do “government stuff”.  We crossed paths again recently and so did this podcast about Red Hat Enterprise Linux Developer Program, related developer subscriptions, etc.  Listen to our conversation and I hope you enjoy Dave and Gunnar’s creative hack of my pic – I don’t get no respect.  😉

An ultra-lightweight high-precision logger for OpenJDK

I had an interesting question from one of our developers here at Red Hat:

“When I was investigating a performance issue in our project after switched to oracle’s jdk7u40, I found a performance regression in class sun.net.www.protocl.http.HttpURLConnection.getOutputStream(). This method takes more cpu time than with jdk7u25.”

And it does, much more time. In fact, when fixedLengthStreamingMode is enabled HttpURLConnection.getOutputStream() takes ten times as long: about 1.2 milliseconds versus 47 microseconds.

What’s new in the core C, math, and thread libraries for Red Hat Enterprise Linux 7?

With the recent release of Red Hat Enterprise Linux 7, we have some great new features to pass along. In this post we walk through the core C, math, and thread libraries and see what is new for developers.

The GNU C Library, or “glibc” as we like to call it, is a core component of Red Hat Enterprise Linux 7 and provides several key OS components including the core ISO C functionality (including the math library), and both BSD and POSIX APIs (including the thread library). The project provides the vast majority of the low-level interfaces that developers use day in and day out with the Linux kernel. You might expect that not much would change, but actually Red Hat Enterprise Linux 7 glibc introduces a large number of changes and improvements. In this article we’ll walk through these.
