n 1998, I got bored by the MS-DOS/Windows world. I was studying Civil Engineering, but in the neighborhood of my school was the Faculty of Computer Science, and I had some friends there. I began hearing about GNU/Linux from them. I bought a new computer and spent a weekend installing Debian 2.0 and, after a week, I had a graphical interface running on the box. The same year, I joined GPUL the Coruña Linux Users Group, where I learned a lot about tech and Free Software philosophy. Richard Stallman’s "The Right To Read" changed my life definitely. I'm very proud of my LUG (one that is still very much alive). In fact, this year we hosted the Akademy!
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.
Kubernetes and Docker are the latest buzz words in the IT sector. Businesses and IT enthusiasts alike are clamoring to learn more about containerization.
I managed to grab Red Hat software analyst Jason Brooks, who will be speaking at SCaLE 14x about Kubernetes, to ask him a few questions about the software and container movement.
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.
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.
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.
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.”
More kernel/Linux: Linux Update Improves Processor Support
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.
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.
