Debian GNU/Linux 8.7 Released (Update: ISOs Now Available)

The Debian Project has released the seventh update of Debian 8 Jessie. This release ships with tons of security updates, bug fixes, and updated packages. The existing users of Debian 8 need to point the apt package tool to one of the updated Debian mirrors and get the update. The new installation media and ISO images are yet to be published.
Update: Debian 8.7’s ISO images are now available for download. It can be grabbed via these mirrors or download the installation images from here.
Back in early 2015, Debian 8.0 Jessie was released after spending two years in development. This release switched back to GNOME as the default desktop environment choice. Now, the Debian Project is here with the latest update to this long-standing Linux distribution.
The seventh update of Debian 8, i.e. Debian GNU/Linux 8.7, has just been released. As expected, this release fixes tons of existing security issues. Notably, many of the included security advisories were already published and referenced.
Long time Linux users must be knowing that security is one of the primary concern of the Debian Project. The project handles all security-related issues brought to their attention and ensures their fixes in a reasonable time limit.
The release notes for Debian 8.7 include many bug fixes and security updates, which you can find here. The release has 80+ bugfixes and 80+ security patches.
One should also note that Debian GNU/Linux 8.7 isn’t a new version of Debian. Instead, it includes security updates and updated packages. So, if you’re already running Debian 8 Jessie, you don’t need to perform a fresh install. Just update via an updated Debian mirror to get all the new packages.
At the moment, new installation media and CD/DVD images are yet to be published. We’ll be updating the article when the ISO images will be available.
Did you find the Debian GNU/Linux 8.7 release exciting? Don’t forget to share your feedback.

Linux Founder Linus Torvalds: “I Don’t Really Love Other People. I Love Computers”

Do you know that the development of Linux was never started with the intention of making it an open source kernel? At the recent TED conference in Vancouver, Linus Torvalds revealed more interesting facts about his life and working style.
Linux kernel is the world’s biggest open source collaborative project. This would automatically trick your brain into thinking that the person behind the kernel would be someone who loves working with fellow programmers.
Well, proving you wrong, Linux founder, Linus Torvalds, admitted that he originally didn’t intend to make Linux open-source and began working on it as a solitary project. This happened at the TED (Technology, Entertainment and Design) conference in Vancouver.
“It wasn’t open source,” he said. “It was source that was open. There was no intention.”
“I’m actually not a people person. I don’t really love other people. I love computers,” the legendary software engineer Linus Torvalds said in an interview with Chris Anderson at the TED conference.
He accepted the fact that with time he has learned that having different people on a project is very important.
However, it shouldn’t be much shocking as Linus is known for his outspoken behaviour and occasional rants. In the interview, he was very open and revealed that he loves to work at home in an office.
“It is the most boring office you’ll ever see,” he said. “I often work in my bathrobe, and I have to have complete silence.”
When asked about his future plans or projects, he said he doesn’t have one. He said, “I don’t have an agenda” and he’s still happy working on Linux.
“I am not a visionary. I’m an engineer. I’m happy with the people who are wandering around looking at the stars but I am looking at the ground and I want to fix the pothole before I fall in.”
Another fact we came to know at the talk: Linus Torvalds considers Thomas Alva Edison greater than Nikola Tesla. Sorry, Larry Page and Elon Musk!
