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 The goal of her project was replacing out-of-date API uses and deprecated functions and macros in the Linux kernel with more modern equivalents.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.”

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.
Last week we published an article regarding the ongoing feud between the Android-x86 and Console OS projects, and it looks like there is an intense debate in the community. Since we already know what the Android-x86 leader thinks, we also had a talk with the CEO of Console OS Inc. to get his side of the story.
Sylvia Sanchez is a Fedora user and contributor living in Uruguay. She started using Linux ten years ago when she bought her first computer. Sanchez recalls, “My first computer came with Guadalinex, an Ubuntu-based distribution, promoted by the government of Andalusia, Spain.” In an odd twist, Sylvia was converted to Fedora at an Ubuntu release party. She has been a Fedora user since Fedora 16. Her childhood heroes are Wonder Woman and Spiderman. Milanesas with salad and fried potatoes is her favorite food. She is an aviation enthusiast who loves airplanes and studying history. She recently started a personal blog called Crossing the Air.
