In the previous tutorial, we learned how to create zpool's and a ZFS filesystem or dataset. In this tutorial, I will show you step by step how to work with ZFS snapshots, clones, and replication. Snapshot, clone and replication are the most powerful features of the ZFS filesystem.

The $15 “Pine A64” SBC runs Linux or Android on a quad-core 64-bit Allwinner A4 SoC, and features dual expansion buses, one of which is Pi 2 compatible. Roll over Raspberry Pi — there’s a new price/performance leader among hacker SBCs, and its name is Pine A64. Fremont, Calif. based startup Pine64 quickly blew past […]

Not all users worry about the kernel. Often the kernel becomes more important to users when: system hardware is new and not yet working perfectly in Linux system hardware behaves differently after a kernel update Arguably, though, the kernel’s the most important part of... Continue Reading →

Linux capabilities are one of the more fluid and less defined regions of kernel development. Linus Torvalds typically has no trouble violating POSIX standards if he sees a better way of doing something. In the case of filesystem capabilities, however, there's no standard to violate.

The power of Git, Docker, and continuous integration (CI) can be leveraged to make TeX document compilation easy while keeping track of different variants and versions. On the top of these technologies, a flexible workflow can be developed to reflect successive changes in TeX documents in each PDF—versioned with a progressive number, say document-v4.pdf.

Mozilla has ceased development and sales of its open source, Linux-based Firefox OS mobile distribution, although the code may infuse future IoT projects.

Do you think music software is only the domain of expensive proprietary software? Think again. There are literally hundreds of applications out there designed by, and for, those with a musical bent. Music projects, including many projects specifically for the Linux operating system, flourish in the open source community as musicians take to coding to produce tools to make their lives easier. read more

Buying a media device that needs a special driver and/or connectivity suite to navigate and update its contents is a common case nowadays, and has been ever since manufacturers decided that it would be a good idea to just limit the access that users can have on the products that they bought. This may not be a huge problem to Windows and Mac OS users who can simply download the manufacturer's suite and use it to connect to their device, but Linux is often (if not always) left unsupported in that part. The first time I encountered this problem was with the first generation of iPods and Creative Zen players that refused to show any contents on the File Manager when connected via the USB port, and then came the newest generations of Android devices which do the same. In this quick guide, we will see how we can overcome this problem, and connect our media device on our Linux system.

Best couples complement each other, and each member of the couple contributes unique and irreplaceable parts to the whole. But some couples are very odd. Such is the case with our best couple this year: the tar and ssh commands. read more

Now that encryption has been elevated to a default technology on mobile devices, the government has heightened its “Going Dark” rhetoric, again on Wednesday insisting during a Senate Judicial Committee hearing that Silicon Valley figure out how to deliver plain-text communication between criminal and terror suspects to law enforcement.

It may be a relatively niche market, but not all video editing is done in post production. There are use cases for live, on-the-fly video editing and basic compositing. You've seen it done yourself, whether you realize it or not—news broadcasts, live webcasts, and live TV events usually use multiple-camera setups controlled by one central software suite. read more

We recently interviewed Dan Mossor on how he uses Fedora. This is part of a series on the Fedora Magazine where we profile Fedora users and how they use Fedora to get things done.

Aimed at variety of embedded, data storage, medical and industrial applications, the CSB502SSD follows Bud Griffin’s successful Kickstarter launch this summer of the PiDrive SSD expansion card. Like the PiDrive, which was offered to backers for $29, or $79 with a 128GB mSATA solid state drive, the CSB502SSD plugs directly into one of the Raspberry Pi’s USB ports.

Welcome back to our continuing series on systemd features. As you've seen in our previous articles, systemd brings more power and flexibility to service startup and management. Some features in systemd we've covered are for compatibility with the old SysVinit.

Drupal, one of the largest open source projects in the world, is a content management system and application framework that powers millions of websites, web services, and mobile applications.

Like many LJ readers these days, I've been leading a bit of a techno-nomadic lifestyle as of the past few years - jumping from network to network, access point to access point, as I bounce around the real world while maintaining my connection to the Internet and other networks I use on a daily basis.

For years, people have wondered when Google would combine Android and Chrome OS. That day appears to be coming.

Everything is connected around us. This revolution has already started and it will be bigger than previous technology revolutions, including the mobile smartphone revolution. Internet of Things, as many call it today, will fundamentally affect all of us.
