5 steps to becoming a quality Docker contributor
But getting started on a new codebase can be daunting. Docker has many, many lines of code. Fixing even the smallest issue can require reading through a lot of that code and understanding how the pieces all fit together.

LUCI4HPC
The software described in this article is designed for a Beowulf-style cluster. Such a cluster commonly consists of consumer-grade machines and allows for parallel high-performance computing. The system is managed by a head node and accessed via a login node. The actual work is performed by multiple compute nodes. The individual nodes are connected through an internal network. The head and login node need an additional external network connection, while the compute nodes often use an additional high-throughput, low-latency connection between them, such as InfiniBand.

Linode introduces KVM to help it move away from Xen
The upgrade to KVM is very easy to carry out, on a Xen Linode’s dashboard, there is a link on the right sidebar titled ‘Upgrade to KVM’. Once you do the upgrade you should then be switched over to KVM. If you want to set your account to default to KVM for new Linodes just go to your Account Settings and set the ‘Hypervisor Preference’ to KVM, any new Linodes you create will be KVM. On a 1GB instance, one user reported the downtime to be between 8-9 minutes while he switched to KVM.

Who's Afraid of Systemd?
Last year, the free software community was full of debates about systemd, the system manager that replaces init, the process that boots a Linux system. Now that systemd is uneventfully running the latest releases of major distributions like Debian, Fedora, and Ubuntu, you might imagine that opposition to it is melting away -- but you'd be wrong.
Instead, casual references on social media show that the rumors are as common as ever. And while you don't hear much recently about Devuan, the anti-systemd fork of Debian, it is still trudging towards a release while making the same arguments as ever.
The situation is not unique. Some free software circles have always seemed to require an enemy. For instance, in the first decade of the millennium, it was Mono, an adaptation for Linux of Microsoft's .Net. Hundreds of thousands of words were written denouncing Mono, yet today it attracts no attention, although it is still available in repositories.
Perhaps, too, free software users are becoming conservative as they age, as indicated by the user revolts against GNOME and KDE. Yet no precedent comes close to the viciousness of attacks on systemd, or had so little foundation, either.

What will be the future of Linux without Linus?
Linus: I’ve never been much of a visionary — instead of looking at huge plans for the future, I tend to have a rather short time frame of ‘issues in the next few months’. I’m a big believer in that the ‘details’ matter, and if you take care of the details, the big issues will end up sorting themselves out on their own.

If I get hit by a bus, Linux will go on just fine says Linus Torvalds
Just a few days after asking the Linux community to let him take a break, Linus Torvalds has said the project he kicked off 1991 can now get along without him.
He was, characteristically, blunt in his recent interview with Bloomberg, saying Linux would survive his death.

Examining the design patterns
I wanted to share a brief update on the Outreachy project that Gina and I are working on, where Gina is preparing for a usability test in GNOME.
So far, we've been in an "information gathering" mode, where she has been learning about some of the basics of usability testing. In our next step, Gina will now start doing an analysis in preparation for a usability test.

Plans for GNOME’s apps
I’ve been a bit quiet about GNOME’s applications of late. This isn’t because nothing has been happening, though – quite the opposite. We’ve been steadily working away behind the scenes, and our application designs have evolved considerably.

Why I use Gentoo Linux (and if you develop software you should too)
I first discovered Gentoo Linux when I left Oracle/Sun in 2010, gave up my Mac and decided to experiment with creating a mac-like desktop experience on Linux. The initial reason was the optimizations you can do to squeeze every bit of performance out of your hardware (I'd bought a cheap Lenovo laptop).

Fedora 22 - workstation - Gnome - Do not disturb
Fedora 22 comes with the newest version of Gnome - 3.16. You've probably heard about this already. The new version brought quite a few shiny changes, a major one of which was a brand new notification area. You don't have a notification bar at the bottom any more, your notifications now come up at the top with the calendar. It's really neat! More information can be found in the release notes here.

Testing rawhide apps using xdg-app
An important aspect of xdg-app is application sandboxing, which will require application changes to use sandbox-specific APIs. However, xdg-app is also a good way to deploy and run non-sandboxed (or partially sandboxed) regular applications.

IRC on Hubs
Still, since the idea for hubs is also to help new contributors get integrated more smoothly into the Fedora community, an effective way to message people did seem like it would be valuable. Since the team/project hubs will have the ability to include an embedded IRC channel, using IRC to send private messages seemed logical. But Fedora Hubs is not an IRC client – it will use IRC to send private messages between users and to enable the channel discussions, but every channel must be directly associated with a hub and the messaging interface will only support messages between Hubs users, not to anyone external. This is an active design choice that Mo and I made, based on the concept of keeping the hub as the central organizing principle of this app in order to help fend off scope creep.

Linux Mint 17.2 'Rafaela' RC now available
Ubuntu is one of the best overall Linux distributions, but it does have its fair share of detractors. Many people dislike the direction Canonical takes sometimes, including the much-maligned Unity desktop environment. Truth be told, I rather like Unity, but I can understand why some people prefer different desktop environments.

US Navy Soliciting Zero Days
The National Security Agency may find and purchase zero days, but that doesn’t mean it’s sharing its hoard with other government agencies such as the U.S. Navy, which apparently is in the market for some unpatched, undisclosed vulnerabilities of its own.
A request for proposal posted last Wednesday—which has since been taken down—to FedBizOpps.gov was a solicitation by the Naval Supply Systems Command seeking a CMMI-3 (Capability Maturity Model Integration) contractor capable of producing operational exploits that integrate with commonly used exploitation frameworks, the RFP said.

Your data is at risk if you are running iOS or Mac OS X
Six university researchers from Indiana University have revealed that Apple’s password manager, Keychain, is susceptible to hackers. If exploited, the flaw would give a hacker access to the users passwords. The really worrying thing here is that Apple has known about the issue for months and still hasn’t managed to issue a fix.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
