PHP for Non-Developers

LinuxJournal - Tue, 2015, Jun30 - 07:00

After years of making it clear that I'm not a developer in just about every article I've written here at Linux Journal, I do have a confession to make. I can write the "Hello World" equivalent in almost every programming language out there. In assembly, it might have been "1+1", but my lack of advanced skills should be evident. more>>

LinuxJournal - Mon, 2015, Jun29 - 08:07
Centrally managing Windows users, group policy and entitlements through Active Directory is a blessing for Windows IT, but leaves RHEL IT out in the cold. Native tools only go so far. more>>

Secure Server Deployments in Hostile Territory

LinuxJournal - Thu, 2015, Jun25 - 11:25

Would you change what you said on the phone, if you knew someone malicious was listening? Whether or not you view the NSA as malicious, I imagine that after reading the NSA coverage on Linux Journal, some of you found yourselves modifying your behavior. The same thing happened to me when I started deploying servers into a public cloud (EC2 in my case). more>>

Django Templates

LinuxJournal - Wed, 2015, Jun24 - 07:00

In my last article (February 2015), I explained how to create a simple Django project ("atfproject") and inside that, create a simple application (atfapp). The application worked in that if you went to the URL http://localhost:8000/hello/Reuven, you got the text "hello, Reuven". more>>

Attack of the Drones

LinuxJournal - Tue, 2015, Jun23 - 08:24

With the price and size of computer hardware steadily decreasing, it's becoming more viable to use embedded Linux systems to control small robots and drones. There are plenty of projects for Raspberry Pi, but not everyone wants to build a drone from scratch. That's why enthusiasts will be pleased to hear about the new drones from Parrot.

Physics Analysis Workstation

LinuxJournal - Tue, 2015, Jun23 - 07:00

CERN is the European Laboratory for Particle Physics. It has been in the news quite a bit lately with the discovery of the Higgs Boson at the Large Hadron Collider. Something that many people may not know is that it also has a long tradition of developing software for scientific use. more>>

The AtoMiC Toolkit!

LinuxJournal - Fri, 2015, Jun19 - 09:57

If you're a cord cutter (and a nerd), you most likely have a server or two dedicated to serving and possibly retrieving videos from the Internet. Programs like Kodi and Plex are awesome for media delivery; however, there's more to a complete system than just playing the videos. more>>

diff -u: What's New in Kernel Development

LinuxJournal - Wed, 2015, Jun17 - 13:15

When you run a program as setuid, it runs with all the permissions of that user. And if the program spawns new processes, they inherit the same permissions. Not so with filesystem capabilities. When you run a program with a set of capabilities, the processes it spawns do not have those capabilities by default; they must be given explicitly. more>>

LUCI4HPC

LinuxJournal - Tue, 2015, Jun16 - 12:07

Today's computational needs in diverse fields cannot be met by a single computer. Such areas include weather forecasting, astronomy, aerodynamics simulations for cars, material sciences and computational drug design. This makes it necessary to combine multiple computers into one system, a so-called computer cluster, to obtain the required computational power. more>>

Gettin' Sticky with It

LinuxJournal - Thu, 2015, Jun11 - 14:12

In last month's issue, I talked about Linux permissions (see "It's Better to Ask Forgiveness..." in the May 2015 UpFront section). I could have covered SUID, GUID and sticky bit in the same article, but it seemed like a lot to cover in one sitting. more>>

Android Candy: Cloud Bonding

LinuxJournal - Tue, 2015, Jun09 - 13:48

Although the title might sound like some new-fangled tech jargon, I'm actually referring to a fairly simple Android app called "Unclouded." If you're a Dropbox user who also has things stored in Google Drive, Unclouded is a single interface to multiple file syncing backends. more>>

Jailhouse

LinuxJournal - Mon, 2015, Jun08 - 10:58

Because you're a reader of Linux Journal, you probably already know that Linux has a rich virtualization ecosystem. KVM is the de facto standard, and VirtualBox is widely used for desktop virtualization. Veterans should remember Xen (it's still in a good shape, by the way), and there is also VMware (which isn't free but runs on Linux as well). more>>

Non-Linux FOSS: Vienna, Not Just for Sausages

LinuxJournal - Tue, 2015, Jun02 - 12:51

Although the technology itself has been around for a while, RSS is still the way most people consume Web content. When Google Reader was ended a few years back, there was a scramble to find the perfect alternative. You may remember my series of articles on Tiny Tiny RSS, Comma Feed and a handful of other Google Reader wannabes. more>>
