First stable release of Apricity debuts

System administration professionals and home users alike share a need for the ability to be able to quickly and reliably make one-to-one copies of entire disks, both for the purposes of backup and recovery, as well as the process of easing deployments and complete refresh repairs and upgrades of existing systems. read more

Is it possible to produce professional media on Linux using free, open source software? We at Dototot believe so. We run Linux exclusively (Mint is our preferred flavor) and use free, open source software when viable.

Flaws were being discussed public, but not officially revealed to users The developers of FreeBSD have announced they'll change the way they go about their business , after users queried why known vulnerabilities weren't being communicated to users.…

I've said it before, and I'll say it again: In open organizations, leaders can emerge from anywhere. read more

In my last article, "Fancy Tricks for Changing Numberic Base", I explored the surprising ability of the Linux shell to convert numeric bases on the fly, including this sweet little snippet that converts FF hexadecimal into decimal notation:

10787 files changed, 612208 insertions, 272098 deletions and lots of doc updates Linux overlord Linus Torvalds has loosed the first release candidate for version 4.8 of the Linux Kernel.…

Versalogic’s sandwich-style “Osprey” SBC offers Atom E3800 SoCs, dual GbE ports, dual mini-PCIe slots, MIL-STD-202G ruggedization, and -40 to 85°C support. Like Versalogic’s recent BayCat and earlier Bengal single-board computers, the Osprey is based on Intel’s “Bay Trail” Atom E38xx family of SoCs. Unlike those boards, which conform to 4.2 x 3.8-inch (107 x 97mm) […]

Welcome to part 6 of our Linux Foundation Certified Engineer Training Course sneak peek blog. This is the last blog in this series, and today we will test our knowledge with quizzes and exercises. The answers are at the bottom.

FOSS (free and open source software) conferences are full of talks about how to improve your code, or how you manage your code, or what the latest and greatest languages and tools are. But a successful open source project is about more than good code. First, let's talk about what success is, because success isn't a guarantee. read more

Video editing and visual effects are two closely related fields. They're also dominated by expensive proprietary software. There are open-source alternatives to some of these packages, and some of them stand up very well by comparison.

This article explains how to use the nginx HttpLimitReqModule to limit the number of requests for a given session. This is useful, for example, if your site is hammered by a bot doing multiple requests per second and thus increasing your server load. With the ngx_http_limit_req_module, you can define a rate limit, and if a visitor exceeds this rate, he will get a 503 error.

Docker and microservices-based architectures have expanded our horizons with respect to how the industry builds and supports applications at scale, says Corey Quinn, Director of DevOps at FutureAdvisor and an early developer behind SaltStack. Nonetheless, Quinn, in his LinuxCon and ContainerCon North America talk — called “Heresy in the Church of Docker” — will preach caution and present an alternative view of the containerization craze.

"I really appreciate you helping me out," I said as I followed the industrial/organizational psychology expert to the coffee machine, seeking help with a feedback survey for my newly formed associate engagement program. "I've never done anything like this before, so I have absolutely no clue what I'm doing." She looked incredulous. "I'm convinced you know exactly what you're doing," she said. read more

Kirigami, KDE’s lightweight user interface framework for mobile and convergent applications, which was first announced in March, is now publicly released! This framework allows Qt developers to easily create applications that run on most major mobile and desktop platforms without modification (though adapted user interfaces for different form-factors are supported and recommended for optimal user experience). It extends the touch-friendly Qt Quick Controls with larger application building blocks, following the design philosophy laid out in the Kirigami Human Interface Guidelines.

Fundamentally, all major software, even open source, was designed before image-based containers. This means that putting software inside of containers is fundamentally a platform migration. This also means that some programs are easy to migrate into containers, while others are more difficult. read more

Less is more, from EE to SE The future of Java Enterprise Edition is on many developers' minds. After the community came to the conclusion that the platform’s progress has come to a standstill, a plethora of initiatives has arisen with the goal of encouraging Oracle to pick up the work on Java EE 8 again.…

Back in 1998 when I discovered Linux and open source, I never would have believed that I would make a career out of this. Back in those days I didn't have a clue about what I wanted to do, but I knew I wanted it to involve technology in some way. read more

The latest Android vulnerability to fret about isn't limited to any particular device, or any specific firmware version. That's because it doesn't start with Android at all, but with Qualcomm, the company that provides internal components for hardware manufacturers. Lots of them. In this case, 900 million Android smartphones with Qualcomm inside are at risk, and fixing them will be no easy task.

Released in 1995, Java went from a language running in a browser to the ubiquitous platform of today, one which underpins the entire industry and with deep tentacles in enterprise IT.
