First OpenWrt Summit co-locates with ELCE

The Imagination backed Prpl Foundation announced a free OpenWrt Summit to be held in Dublin on Oct. 8, and co-located with Embedded Linux Conference Europe. The Prpl Foundation, which Imagination Technologies founded last year to promote the development of MIPS-based Linux and Android software, is hosting a one-day conference devoted to the lightweight OpenWrt Linux distribution. The OpenWrt Summit will be held in Dublin, Ireland on Oct. 8, directly following the LinuxCon + CloudOpen + Embedded Linux Conference Europe (ELCE) conference, which is being held Oct. 5-7. The free OpenWrt Summit will be located at the same Conference Centre Dublin venue.

Migrate a LAMP application to Bluemix

LAMP is a commonly used open source stack for running dynamic websites and web applications. Originally, the acronym stood for the Linux operating system, the Apache HTTP Server, the MySQL database, and the PHP programming language. Over time, LAMP has come to represent a more generic open source software stack for PHP apps. For example, the Apache web server can be replaced by nginx, and the MySQL database server has alternatives such as PostgreSQL.

Disney home networking is not just for toys

Disney Research has demonstrated an LED-to-LED networking method whereby toys, wearables, mobile devices, and IoT gizmos could communicate with one another. Disney Research has demonstrated an LED-to-LED “Linux Light Bulb” networking technology that would let toys communicate with each other, thereby bringing us one step closer to the reality of Disney/Pixar’s Toy Story. Instead of lip-syncing to the voice of Tom Hanks, however, Woody would argue with Buzz Lightyear with a flash of his eyes.

How to Install and Set Up Tor Browser on Linux

  • Howtoforge Linux Howtos and Tutorials; By Bill Toulas (Posted by Scott_Ruecker on Sep 17, 2015 3:42 PM EDT)
  • Story Type: News Story; Groups: Linux
Tor Browser is the official internet browser tool of the Tor Network project. This software is aimed at serving users who want to browse in full anonymity, preventing surveillance of any kind. This is achieved by bouncing your communications around a distributed network or relays, making eavesdropping very difficult, if not practically impossible.

Rugged, secure SMARC COM runs Yocto on Tegra K1

Calao claims its “SMC-NTKECalao claims its “SMC-NTKE1? is the first SMARC COM with a Tegra K1 SoC. The rugged module offers Yocto Linux, crypto and TPM security, and up to 64GB eMMC. Nvidia’s quad-core Tegra K1 SoC, which features a 192-core Kepler GPU, has appeared on Linux-ready computer-on-modules including Seco’s SECOMExp-TK1 COM Express Type 6 Compact COM and the GE Intelligent Platforms mCOM10K1 COM Express Type 10 Mini module. Now, Calao Systems has launched what it claims is the first Tegra K1-based module to adopt the 82 x 50mm SMARC form-factor. Other Tegra-based SMARC modules include Kontron’s SMARC-sAT30, which used the earlier Tegra 3.

Tor becomes extra secure as .onion becomes Special-Use Domain Name

The dark web browser Tor has now become extra secure as the .onion url has now been assigned special-use status. The Engineering Task Force (IETF) along with Internet Assigned Numbers Authority, part of ICANN, has granted formal recognition to the .onion domain, adding it to the list of Special-Use Domain Names.

SUSE – “Will not diverge from its Open Source roots!”

No one had a busier LinuxCon show than the folks at SUSE. Yet still they were gracious enough, and care enough about the community, to sit down for a talk with Linux Journal. We had the distinct pleasure of sitting down for a few minutes during LinuxCon with Michael Miller, SUSE’s VP of Global Alliances and Marketing, to talk about their announcements, their future and the future of Linux,

5 open source alternatives to Gmail

Gmail has enjoyed phenomenal success, and regardless of which study you choose to look at for exact numbers, there's no doubt that Gmail is towards the top of the pack when it comes to market share. For certain circles, Gmail has become synonymous with email, or at least with webmail. Many appreciate its clean interface and the simple ability to access their inbox from anywhere.

Server monitoring with Munin and Monit on CentOS 7

In this article, I will describe how you can monitor your CentOS 7 server with Munin and Monit. Munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas Monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.

Spiderlike bots controller runs Snappy Ubuntu on Raspberry Pi 2

Erle Robotics has launched a six-legged Erle-Spider robot on Indiegogo, with an Erle-Brain 2 controller that runs Ubuntu Snappy and ROS on a Raspberry Pi 2. Spain’s Erle Robotics was the first company to create an Unmanned Aerial Vehicle (UAV) using the Linux version of 3DR’s typically Arduino-based APM (ArduPilot Mega) drone autopilot platform. The company started with the Erle-Copter Ubuntu Edition quadrotor, and then shipped its almost identical Ubuntu Snappy based Erle-Copter Ubuntu Core Special Edition. Now, Erle Robotics has gone to Indiegogo to launch a six-legged “Erle-Spider” robot that similarly runs on Snappy Ubuntu Core and the Robot Operating System (ROS) open source robotics platform.

OpenSSL Security: A Year in Review

Over the last 10 years, OpenSSL has published advisories on over 100 vulnerabilities. Many more were likely silently fixed in the early days, but in the past year our goal has been to establish a clear public record. In September 2014, the team adopted a security policy that defines how we handle vulnerability reports. One year later, I'm very happy to conclude that our policy is enforced, and working well.

Intel unveils its 6th Gen Core processors

Intel debuted its 6th Gen Core (Skylake) processors, ranging from 4.5 Watt TDP SoCs with internal I/O hubs, to 45+ Watt honkers with external I/O hub chips. Intel bills the 6th Gen Intel Core as its “most scalable processor family ever.” After more than four years of development, Intel’s “Skylake” architecture is now breathing life into 48 processors organized in four sets — Y-series, U-series, H-series, and S-series — and ranging from 4.5 to 91 Watt TDPs.

How to automatically dim your screen on Linux

When you start spending the majority of your time in front of a computer, natural questions start arising. Is this healthy? How can I diminish the strain on my eyes? Why is the sunlight burning me? Although active research is still going on to answer these questions, a lot of programmers have already adopted a few applications to make their daily habits a little healthier for their eyes. Among those applications, there are two which I found particularly interesting: Calise and Redshift.

News: Linux 4.2 Released Improving Cryptography Options

After eight release candidates, Linux 4.2 is now available, marking one of the longer development cycles in the last few years. The longer cycle was likely only the result of an abundance of caution on Linus Torvalds' part and some travel (Linuxcon) too.

How to switch from NetworkManager to systemd-networkd on Linux

In the world of Linux, adoption of systemd has been a subject of heated controversy, and the debate between its proponents and critics is still going on. As of today, most major Linux distributions have adopted systemd as a default init system.

Linux helps rural student transform rocky academic start into FOSS confidence

Perundurai is a small town in the district of Erode, located in the state of Tamilnadu in southern India. From Perundurai, it is a ~1 hour car ride west to a small, rural village called Sullippalayam. This is the town where I was born, grew up, and still live, with my family.

Rugged Bay Trail Pico-ITX SBC has multiple expansion paths

Advantech’s COM-like “MIO-3260? Pico-ITX SBC runs Linux on a Bay Trail SoC and offers a PCIe/mSATA slot, MI/O expansion, and optional -40 to 85°C operation. Like Advantech’s MIO-2263, which was announced in May, the MIO-3260 is a 100 x 72mm Pico-ITX board that supports a quad-core Intel Celeron or dual-core Intel Atom from the 22nm Bay Trail generation. Like the earlier, Atom Cedarview generation MIO-2262, the MIO-3260 lacks real-world ports, thereby acting as much like a computer-on-module as a single board computer.

The Raspberry Pi is succeeding in ways its makers almost imagined

Kids don't want to code. They want to solve problems us oldies can't perceive. “Grandpa is getting pretty old. Out there all alone on that farm, he has no one to look in on him, just to see if he’s ok. He’ll use the landline, but he’s beyond of the range of mobile, and he’s never been really great with computers. No Skype or emails. Grandpa does have internet. So I built this for him."

Another root hole in OS X. We know it, you know it, the bad people know it, and no patch exists

Be careful what you run. If you're using OS X Yosemite, watch out for malware exploiting a new way to take complete control of your Mac. A vulnerability has been found in Apple's operating system that allows ordinary software on the computer to gain all-powerful root privileges, allowing dodgy apps to install new programs, create users, delete users, trash the system, and so on, without the owner's permission.
