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

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.”

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.

Minimal Linux Live

Minimal Linux Live is, as the name suggests, a very minimal Linux distribution which can be run live from a CD, DVD or USB thumb drive. One of the things which set Minimal Linux Live (MLL) apart from other distributions is that, while the distribution is available through a 7MB ISO file download, the project is designed to be built from source code using a shell script. The idea is that we can download scripts that will build MLL on an existing Linux distribution. Assuming we have the proper compiler tools on our current distribution, simply running a single shell script and waiting a while will produce a bootable ISO featuring the MLL operating system. Yet another option the MLL project gives us is running the distribution inside a web browser using a JavaScript virtual machine. The browser-based virtual machine running MLL can be found on the project's website, under the Emulator tab. This gives us a chance to try out the operating system in our web browser without installing or building anything. I decided to try the MLL build process to see if it would work and how long it would take if everything went smoothly. I also wanted to find out just how much functionality such a small distribution could offer. The project's documentation mostly covers building MLL on Ubuntu and Linux Mint and so I decided to build MLL on a copy of Ubuntu 16.04 I had running in a virtual machine. The steps to build MLL are fairly straight forward. On Ubuntu, we first install six packages to make sure we have all the required dependencies. Then we download an archive containing MLL's build scripts. Then we unpack the archive and run the build script. We just need to type four commands in Ubuntu's virtual terminal to kick-start the build process. Read more
