The state of container security

Filed under

Security

This is a gross over-simplification, but multiple containers on a host is just the next logical step from multiple virtual machines on a host. Because those containers are tightly controlled by the kernel namespaced, Security Enhanced Linux, Linux kernel capabilities, and the like, you can be assured that the risk is minimal.

Young maker talks software defined radio, open source, and mentors

Interviews
OSS

Schuyler St. Leger is one of the superheroes of the maker movement. He's a speaker, young maker, and was featured in Make magazine. His famous presentation, Why I love my 3-D Printer has received over 300,000 views on YouTube.

Schuyler is keynoting at SCaLE 14x, where he'll talk about open source radio and how it's impacting the world around us. We're surrounded by radios in smartphones, tablets, laptops, and Wi-Fi access points, yet we often fail to realize their ubiquitous presence. The airwaves are a fantastic space for exploration, but where do we begin? Open source radio combined with open hardware is a rich space for exploration and experimentation.

Using strace to track system calls in Linux

Filed under
Linux
Interviews

Strace is a tool used to intercept system calls from your application to the Linux kernel. I find strace is invaluable for system administrators for two main reasons.

First off, we do not always have the source code of an application available, but we may still need to know what an application is doing. This can be anything from which files are opened, how much memory is being allocated or even why an application is crashing repeatedly.
Secondly, even if we do have the code, being a system administrator doesn't imply being a developer. We may not know how to follow the code. I find that looking at system calls as opposed to lines of code is a bit more descriptive

I have been involved with Linux and open source since the mid-1990s, and Scylla is a natural progression for open source to move up the stack and provide more value for some of the most demanding companies out there. The problems involved in running a resilient database are some of the hardest and most valuable in IT today.

3 smart GIMP tricks

Filed under
GNU
Interviews

Honestly, I think a lot of the people claiming GIMP isn't as good as Photoshop are people who have invested a lot in learning Photoshop and want an excuse not to learn a new and different tool. If the GIMP team spent much time trying to make everything just like Photoshop, they'd never have time to implement great new features.

It's true there are some nice features Photoshop has that GIMP doesn't. Some are being addressed for GIMP 3.0, like high-color images. A lot of people will be very happy to see that. Other features, like non-destructive editing and CMYK, are still wish-list items that will have to wait until later.

Linux Foundation Scholarship Recipient: Vaishali Thakkar

Linux
Interviews

The Linux Foundation’s Training Scholarship Program has awarded 34 scholarships totaling more than $100,000 in free training to students and professionals during the past five years. In this series, we are featuring recent scholarship recipients with the hope of inspiring others.

Vaishali Thakkar is a scholarship recipient in the Kernel Guru category. She lives in India and recently completed an Outreachy internship on project Coccinelle. The goal of her project was replacing out-of-date API uses and deprecated functions and macros in the Linux kernel with more modern equivalents. She began contributing to the Linux kernel almost a year ago, and her first contribution was running a Coccinelle semantic patch over staging directory files. She says the excitement of having that first patch accepted was amazing, and she hopes some day to have her dream job of “Linux Kernel Engineer.”

Brian Proffitt: How do you Fedora?

Red Hat
Interviews

Brian has been involved with Linux for a long time. In the summer of 1999, he was asked to write a book about Sun StarOffice 5.1 for Linux. This was a challenge for Brian as he had never run Linux before. “I got a hold of a Caldera OpenLinux CD set and installed it on a friend’s spare PC.” He was hooked on Linux when he was able to play an in-memory game of Tetris while the operating system was being installed.

Open source communities need mentors

Filed under
Interviews
OSS

To me it seems a natural pairing because they are two things I am passionate about and things that I do and use every single day. So many of the principles of open source correlate with the positive outcomes most desired for children: collaboration, participation, and transparency (honesty, integrity, openness). For children who are interested in how things work, open source software can give them that behind-the-scenes peek. I love teaching children about open source because there are so many ways they can get their hands dirty and get involved in communities and meet people who share their particular interests. There are many projects that were developed with children in mind, like the great work done by Sugar Labs.

HTC U11 Life (Android One) review: Keep it simple

Android One has arrived in Europe, and HTC is one of the first manufacturers to ship an affordable, Google-branded phone. The Android One badge made its debut in India and parts of Asia, as Google emphasized quality software on super-cheap hardware. But with its latest round of "One" handsets, the prices are higher, the products more premium, and the hand on the software rudder a little firmer. The Android One U11 Life — unlike the T-Mobile U.S. version we reviewed separately, running HTC Sense — runs Android 8.0 Oreo out of the box, and comes with the promise of timely updates to future versions. It takes the fundamentals of HTC's flagship phone and downscales it into a smaller size, while trimming the specs back to the essentials. There's a Snapdragon 630 processor — Qualcomm's latest mid-ranger, and the successor to the very capable 625/626 — along with 3GB or 4GB of RAM, and 32 or 64GB of storage, plus microSD. I've been using the 3/32GB model for the past couple of weeks, however the UK will be getting the more capacious 4/64GB model when it goes on sale. Read more

The power of open source: Why GitLab's move to a Developer Certificate of Origin benefits the developer community

Over the past few years, open source software has transformed the way enterprises operate and ship code. In an era where companies are striving to deliver the next best application, enterprises are turning to the sea of open source contributors to create projects faster and more effectively than ever before. For instance, 65 percent of companies surveyed in The Black Duck Future of Open Source Survey reveal they are contributing to open source projects – with 59 percent doing so to gain a competitive edge. As open source continues to have a positive influence on software development, it’s important for developers to continue to participate in and contribute to open source projects. Read more
