Start developing Android apps on Fedora in 10 minutes

Filed under
Android
Red Hat
HowTos

Android is one of the most popular mobile operating systems (and it is based on the Linux kernel too.) However, diving into developing apps for Android can appear to be a bit daunting at first. The following how-to runs you through the basics of setting up an Android development environment on your Fedora machine. The basic workflow is to download the Android SDK, use the SDK to generate a quick first “hello world” application, then test out that application with either a physical Android device or the Android emulator.

DNF v.s. Yum

Filed under
Red Hat
HowTos

A lot has been said on fedora-devel in the last few weeks about DNF and Yum. I thought it might be useful to contribute my own views, considering I’ve spent the last half-decade consuming the internal Yum API and the last couple of years helping to design the replacement with about half a dozen of the packaging team here at Red Hat. I’m also a person who unsuccessfully tried to replace Yum completely with Zif in fedora a few years ago, so I know quite a bit about packaging systems and metadata parsing.

Recovering Linux after catastrophic deletion

Filed under
GNU
Linux
HowTos

A recurring Linux joke / horror story is running the command rm –rf /. Imagine if it actually happened? What would or could you do to recover?

Linux specialist Kyle Kelley recently decided to see what happened if he launched a new Linux server and ran rm –rf / as root.

This command is the remove (delete) command, with the flags –rf indicating to run recursively down all folders and subfolders, and to force deletion even if the file is ordinarily read-only. The / indicates the command is to run from the top-most root directory in Linux.

KaOS ISO 2014.12

KaOS is very proud to announce the availability of the December release of a new stable ISO. This ISO marks two major milestones for this distribution. Since it’s inception almost two years ago, a need to be ready for UEFI installs has always been a priority. That was tied though to getting a modern Qt based installer that could handle such UEFI installs. With this ISO, both are implemented. Read more

Old FOSS Friend & Foe Represents Sony in Hack

Boies, along with three attorneys representing the States, brought Microsoft to it’s knees — or so it seemed at the time. On November 5, 1999, Judge Thomas Penfield Jackson found that Windows dominance on the PC made the company a monopoly and that the company had taken illegal actions against Apple, Java, Netscape, Lotus Notes, RealNetworks, Linux, and others in order to maintain that monopoly. He ordered Microsoft broken in two, with one company producing Windows and another handling all other Microsoft software. As we all know, Judge Jackson’s solution was never implemented. Although an appeals court upheld the verdict against Redmond, the breakup of the company was overturned and sent back to the lower court for a review by a new judge. Two years later, in September, 2001, under the Bush Administration, the DOJ announced that it was no longer seeking the breakup of Microsoft, and in November reached a settlement which California, Connecticut, Iowa, Florida, Kansas, Minnesota, Utah, Virginia and Massachusetts opposed. The settlement basically required Microsoft to share its APIs and appoint a three person panel that would have complete access to Microsoft’s systems, records, and source code for five years. The settlement didn’t require Microsoft to change any code or stop the company from tying additional software with Windows. Additionally, the DOJ did not require Microsoft to change any of its code.
