Why the result of Top is not consistent with Psutil
Dear all,
I have written a script and measure the CPU utlization of the script using psutil inside it. When I compare the result with Top, there was a big differece even thought I used -d to minimize the delay? Why ?
Thank you!
Best,

Announcing Our First SysAdmin Linux Certification Workshop at LinuxCon
Are you looking for a way to jumpstart your IT career or move mid-career to managing Linux systems? The 2015 Linux Jobs Report showed that certification is a great way to do this, with 44 percent of managers reporting they are more likely to hire someone with a certification. That’s one reason we created our Linux Foundation Certified SysAdmin program. If you have Linux skills, show it off with a convenient, neutral exam that has the backing of the Linux Foundation.
This year for the first time we’ll host an in person SysAdmin certification prep workshop the day prior to LinuxCon in Seattle, Sunday, August 16, 2015. It’s only $69 which is a huge bargain on its own, but as an added bonus includes $100 towards your certification exam. And if you’re attending LinuxCon, CloudOpen and ContainerCon, the cost of the workshop is included in your registration.
Taught by Dr. Jerry Cooperstein, The Linux Foundation’s Training Program Director who developed the Essentials of System Administration course, this workshop will provide the opportunity to dig into topics relevant to taking the exam and to get your questions answered live. Jerry is an amazing Linux talent and teacher so this is a wonderful chance to learn from the best at a very small price.
Since the launch of the Linux Foundation Certified System Administrator exam last August, we have worked to make exam prep materials and courses as accessible as possible. This workshop builds on those initiatives, such as the release of our certification exam prep guide, the bundled Essentials of System Administration course and certification exam offered at an affordable price point, and allowing those who do not pass the exam on their first attempt to retake it for free. But this is a chance to visit Seattle, meet many of us in person and learn a lot about Linux, containers and the newest cloud technologies.
We believe this is a great opportunity to take the first step toward an outstanding career in Linux. Register today, and we’ll see you in Seattle!

Beautiful Material Design-Inspired Papyros Linux Distro Getting Closer to Release
Papyros is getting closer to working release, and the developers are putting the final touches. We’ll soon be able to play with the new distro, even if it’s going to be just a development version.
The Papyros is a Linux distribution that follows the guidelines from Material Design, which have been implemented in the latest Android 5.x Lollipop from Google. There are already a number of themes out there that have been inspired by Material Design, but no one has gone through … (read more)

Buick and GMC join GM’s list of CarPlay and Android Auto brands
![]()
GM has been moving quickly to announce wide-ranging support for Apple’s CarPlay and Google’sAndroid Auto in recent weeks, and the automaker can add two more of its brands to the mix: Buick and GMC, both of which will start adding compatibility this year. CarPlay comes first, hitting the 2016 Buick LaCrosse and Regal alongside GMC’s 2016 Canyon, Yukon and Sierra; Android Auto will follow later. If that approach sounds familiar, it should — it’s the same one that GM is employing with Chevrolet and Cadillac, both of which have already made their connected car announcements.

A Template for Starting Project Documentation

Let’s say you’ve created a program or launched an open source project, and now you have people’s attention. They start to ask more and more questions, taking more and more of your precious developer time to answer. They fill your mailbox, sometimes even spam your IRC channel, often repeating the same questions. You know that you need to provide something in writing to help your users. But where should you start? What tools can you use? What output format do you choose? What subjects must you cover?
