A tour of Google's 2016 open source releases
Open source software enables Google to build things quickly and efficiently without reinventing the wheel, allowing us to focus on solving new problems. We stand on the shoulders of giants, and we know it. This is why we support open source and make it easy for Googlers to release the projects they're working on internally as open source.
We've released more than 20-million lines of open source code to date, including projects such as Android, Angular, Chromium, Kubernetes, and TensorFlow. Our releases also include many projects you may not be familiar with, such as Cartographer, Omnitone, and Yeoman.
Viewing Linux Logs from the Command Line
At some point in your career as a Linux administrator, you are going to have to view log files. After all, they are there for one very important reason...to help you troubleshoot an issue. In fact, every seasoned administrator will immediately tell you that the first thing to be done, when a problem arises, is to view the logs.
And there are plenty of logs to be found: logs for the system, logs for the kernel, for package managers, for Xorg, for the boot process, for Apache, for MySQL… For nearly anything you can think of, there is a log file.
At Long Last, Linux Gets Dynamic Tracing
When the Linux kernel version 4.9 will be released next week, it will come with the last pieces needed to offer to some long-awaited dynamic thread-tracing capabilities.
As the keepers of monitoring and debugging software start using these new kernel calls, some of which have been added to the Linux kernel over the last two years, they will be able to offer much more nuanced, and easier to deploy, system performance tools, noted Brendan Gregg, a Netflix performance systems engineer and author of DTrace Tools, in a presentation at the USENIX LISA 2016 conference, taking place this week in Boston.
