Keeping Linux containers safe and secure

Filed under
Linux
Interviews

Linux containers are helping to change the way that IT operates. In place of large, monolithic virtual machines, organizations are finding effective ways to deploy their applications inside Linux containers, providing for faster speeds, greater density, and increased agility in their operations.

While containers can bring a number of advantages from a security perspective, they come with their own set of security challenges as well. Just as with traditional infrastructure, it is critical to ensure that the system libraries and components running within a container are regularly updated in order to avoid vulnerabilities. But how do you know what is running inside of your containers? To help manage the full set of security challenges facing container technologies, a startup named Anchore is developing an open source project of the same name to bring visibility inside of Linux containers.

Linux
Interviews

AS PART of our visit to LinuxCon this week we’re going to ask five key players in the Linux story the same 10 questions to get an idea of where Linux has been, where it is and where it’s going.

And who better to start with than Linus Torvalds, the often outspoken creator of Linux itself. Torvalds isn’t actually attending the celebrations this year, but was kind enough to chat to the INQUIRER by email.

How I Use Android: Android Central Editor Emeritus Phil Nickinson

Android
Interviews

In the meantime, I was able to convince Phil to step out of his metaphorical kitchen for a few minutes to chat about how he uses Android in his day-to-day life. This is a man who has seen and used practically every Android device over the past several years, after all -- and a fair number of apps and customization tools, to boot.

So what devices does someone with so much knowledge carry around in his own trousers, and how does he make the most of what they have to offer?

Enough with the suspense already. In his own words, this is how Phil Nickinson uses Android.

Linux
Interviews

I started using Linux when I was in school. But at that point, I was limited to Installation and running a few commands. I really started learning and growing my interest in Linux while I was working on my degree in Computer Applications. My first distribution was Red Hat CentOS. I spent many hours learning Linux and enjoyed it.

2016 LiFT Scholarship Winner Ksenija Stanojevic: Learning Linux Driver Development

Filed under
Linux
Interviews

A few years ago I decided to try Linux and it was surprisingly easy to install and use. Since I started with Ubuntu there were already lots of tutorials online for beginners. Initially I was interested in learning about the Linux kernel but using Linux led me to discovery of new tools such as vim, git, and bash shell.

I started experimenting with the kernel over a year ago when I wrote a simple hello module and loaded it into the kernel. After that I started making simple fixes using scripts such as checkpatch.pl and submitting patches. My confidence grew and eventually I joined the Eudyptula challenge to deepen my knowledge and I started making even bigger changes to the kernel tree. After being accepted into the Outreachy program, I had the opportunity to learn more about driver development and also got to work on embedded ARM devices running the Linux operating system.

Ayoub Elyasir: How Do You Fedora?

Filed under
Red Hat
Interviews

Ayoub Elyasir was born and raised in Tripoli, Libya. He currently works as a data engineer at Almadar. He says he’s passionate about “humanity, technology, open source, literature and poetry,” and enjoys swimming, body building and reading. Ayoub includes Steve Jobs and Steve Wozniak as childhood heroes. His favorite food is grilled chicken and hummus.

Ayoub started using Linux years ago. In fact, he told us, “My migration to Linux dates back to 2008 with openSUSE 11.” Ayoub started to use Linux as a curiosity. However, today he uses Linux and open source products completely. He gradually shifted from KDE and openSUSE to Fedora with GNOME.

Linux
Interviews

I grew up with the Windows platform and I saw that we had to pay a license fee to be able to use it, which is something I didn’t want. Then I saw that Linux is the open source system that can be used for free, and we can pretty much do anything we want and more than can be done with Windows.

I've used many open source tools and technologies and I loved the way they work. I am a true fan of Linux and open source.

2016 LiFT Scholarship Winner Kurt Kremitzki: Solving Food Scarcity With Linux and Open Source

Filed under
Linux
Interviews

I was introduced to Linux in the era of Red Hat Linux 9, but I thought it *was* Linux, and when "Enterprise" was added I stopped using it. Several years ago, I picked up Ubuntu and started using it full time. More recently, besides use at home, I applied what knowledge I have of Linux to a robotics competition, using the Raspberry Pi, hosted by the American Society of Agricultural & Biological Engineers in New Orleans last year. When a similar competition was assigned to an introductory Control Theory class I took last semester, the professor opted to have me assist the TA and all my classmates in teaching basic Linux skills and Python programming to do a simple maze following project.

Getting to know elementary: An interview with elementary OS UX Architect

Filed under
GNU
Linux
Interviews

Sometimes the best way to get to know a platform is by "sitting down" with a developer and letting them do the talking about what they are passionate about. When I sent a selection of questions to the elementary OS development team, I had no idea that I'd get back such deep, and thoughtful answers. That's exactly what UX Architect, Cassidy James Blaede brought to the table. And with the release of the next iteration of elementary OS (called Loki) due to hit September 9, 2016, I couldn't think of a better time to have this chat.

Let's jump right in and see what Blaede had to say about elementary, developing, open source, UX, and more.

Keeping DOS alive and kicking with open source

OSS

No, I don't run FreeDOS as my primary system. That would really be impressive!

I run Linux at home. My laptop is a Lenovo X1 Carbon (first gen) running Fedora 24 with GNOME 3.

The tools I use every day include: Google Chrome, Firefox, and GNOMEWeb to browse the web; Gedit to edit text or simple code (such as Bash); GNU Emacs to edit program code (I prefer C); GNOME Terminal to SSH to my personal server and to the FreeDOS website; RhythmBox to listen to music.

I run FreeDOS in a virtual machine. I use DOSEmu if I'm writingFreeDOS code, so I can use GNU Emacs on Linux to write code and immediately compile it in FreeDOS via DOSEmu. That's really convenient because DOSEmu maps a folder in your home directory as the C: drive.

If I need to run FreeDOS as though it's running on hardware, such as testing the upcoming FreeDOS 1.2 release, I use qemu.

What’s the best Linux firewall distro of 2017?

You don’t have to manage a large corporate network to use a dedicated firewall. While your Linux distro will have an impressive firewall – and an equally impressive arsenal of tools to manage it – the advantages don’t extend to the other devices on your network. A typical network has more devices connected to the internet than the total number of computers and laptops in your SOHO. With the onslaught of IoT, it won’t be long before your router doles out IP addresses to your washing machine and microwave as well. The one thing you wouldn’t want in this Jetsonian future is having to rely on your router’s limited firewall capabilities to shield your house – and everyone in it – from the malicious bits and bytes floating about on the internet. A dedicated firewall stands between the internet and internal network, sanitising the traffic flowing into the latter. Setting one up is an involved process both in terms of assembling the hardware and configuring the software. However, there are quite a few distros that help you set up a dedicated firewall with ease, and we’re going to look at the ones that have the best protective open source software and roll them into a convenient and easy to use package.

GNOME and Other Software

  • Nautilus 3.24 – The changes
    Since Nautilus was created, if a user wanted to open a folder where the user didn’t have permissions, for example a system folder where only root has access, it was required to start Nautilus with sudo. However running UI apps under root is strongly discouraged, and to be honest, quite inconvenient. Running any UI app with sudo is actually not even supported in Wayland by design due to the security issues that that conveys.
  • GNOME hackaton in Brno
    Last week, we had a presentation on Google Summer of Code and Outreachy at Brno University of Technology. Around 80 students attended which was a pretty good success considering it was not part of any course. It was a surprise for the uni people as well because the room they booked was only for 60 ppl.
  • Peek Gif Recorder Gets Updated, Now Available from a PPA
    Peek, the nifty animated gif screen capture app for Linux desktops, has been updated. Peek 0.9 reduces the size of temporary files, adds a resolution downsampling option (to help the app use fewer resources when rendering your gif), and introduces fallback support for avconf should ffmpeg be unavailable.
  • Cerebro is an Open Source OS X Spotlight Equivalent for Linux
    Billed as an ‘open-source productivity booster with a brain’, Cerebro is an Electron app able to run across multiple platforms. It’s an extendable, open-source alternative to Spotlight and Alfred on macOS, and Synapse, Kupfer, Ulauncher, GNOME Do, and others on Linux.
  • JBoss Fuse 6.3 integration services for Red Hat OpenShift released
    Red Hat announced the latest update to the Red Hat JBoss Fuse-based integration service on Red Hat OpenShift. With the growth of the Internet of Things (IoT), cloud-based SaaS systems, and new data streams, organizations can face increasing pressure to more quickly deliver innovative new services. Traditional centralized, monolithic ESB-style integration approaches are often ill-suited to support the business in responding to this pressure.

  • Meet the chap open-sourcing US govt code – Paul, an ex-Microsoft anti-piracy engineer [Ed: Used to work for Microsoft and now spreads the GPL ("cancer" according to Microsoft) in the US government]
    The manager of the project, Berg said, really wanted to release MOOSE as open source, but didn't know how to do so. As a result it took 18 months to traverse government bureaucracy and to obtain the necessary permissions. It's now available under the GPL 2.1 license.
