DevOps Fundamentals, Part 5: Consistency in the Pipeline

In this article, we’ll do a quick review of some of the tools and then discuss how to achieve consistency in the pipeline.

Protect the White Hat Hackers Who Are Just Doing Their Jobs

The great irony of defending the world against malware is it requires security researchers to, well, mess with malware. This often leads them into gray areas, where something they might consider legitimate investigation or essential software development could, in the eyes of the law, be seen as criminal behavior.

Tails 3 Offers Easy Anonymity for All

If you’re seriously concerned about privacy, you want to ensure you’re doing all the right things and not leaving behind a trace of what you’ve browsed. There are many reasons for this—some good, some bad...

Automotive Grade Linux Moves to UCB 4.0, Launches Virtualization Workgroup

The Linux Foundation’s Automotive Grade Linux (AGL) project released Unified Code Base (UCB) 4.0 (“Daring Dab”) for Linux-based in-vehicle infotainment (IVI) systems, and added seven new members. The open source group also launched a new virtualization working group that will enable new UCB profiles for telematics, instrument clusters, and head-up-displays (HUDs). In other Linux automotive news, Ubuntu has been spotted in an Uber self-driving car trial (see below).

Linux kernel hardners Grsecurity sue open source's Bruce Perens

In late June, noted open-source programmer Bruce Perens warned that using Grsecurity's Linux kernel security could invite legal trouble. "As a customer, it’s my opinion that you would be subject to both contributory infringement and breach of contract by employing this product in conjunction with the Linux kernel under the no-redistribution policy currently employed by Grsecurity," Perens wrote on his blog. The following month, Perens was invited to court. Grsecurity sued the open-source doyen, his web host, and as-yet-unidentified defendants who may helped him draft that post, for defamation and business interference.

DevOps Fundamentals, Part 4: Patterns and Practices

We are back with more information in our series previewing the DevOps Fundamentals: Implementing Continuous Delivery (LFS261) course from The Linux Foundation. So far, we've looked at high-performing organizations, the value stream, and Continuous Delivery and Deployment.

64-bit Odroid SBC runs Linux on 2GHz quad-core Cortex-A53

Hardkernel unveiled its first 64-bit hacker SBC. The Odroid-C2 matches the layout of the C1+, but has a quad-core, 2GHz Cortex-A53 SoC and a $40 price.

How to monitor OpenFlow messages with packet sniffer

OpenFlow was initially introduced in the academia as a way to enable innovation on production networks which had traditionally been built with close and proprietary networking hardware. OpenFlow offloads the high-level routing/forwarding decisions (control plane) from networking devices such as switches, and moves the control plane on to a separate controller. The networking devices then simply forward traffic, as instructed by the external OpenFlow controller. It is the OpenFlow protocol that is used by the OpenFlow controller to program the networking devices.

Top 10 open source Android app development frameworks

Each of these app development frameworks supports HTML5 or JavaScript as well as CSS, and is open source with at least some version of a free app. If you’re developing Android-based games or complex apps with extensive cloud integration, you’ll probably want to seek out native application development tools. These range from the Java-oriented Android SDK and Android Development Tools (ADT) Eclipse plugin to game-oriented engines like Corona to commercial enterprise platforms like the cloud-oriented Monaca toolsuite.

Google Chrome gets ready to mark all HTTP sites as 'bad'

Google's push for all websites to be HTTPS has so far been all carrot. But the company is now using its big stick: a large red cross through every website that doesn't offer an encrypted connection. A year after Google's Chromium Security team proposed marking all HTTP sites which are non-secure, the company is preparing to implement the policy in Chrome.

5 ways to have a more inclusive event

Girl Develop It is a national non-profit that provides technical education for women—and Sarah Kahn is a co-leader of Raleigh’s local chapter. In this video, she responds to a question she receives quite often: Why don’t more women attend technical conferences and other events? "If you want more women to come to your event, make it friendly," Kahn tells her audience, just before offering fives ways to do so: make the event accessible, post (and enforce) a code of conduct, publicize via non-traditional communication platforms, build networks, and extend personal invitations.

$10 Orange Pi One pits quad-core Cortex-A7 against Pi Zero

Shenzhen Xunlong launched a $10, Linux- and Android-friendly “Orange Pi One” hacker board with a quad-core Cortex-A7 SoC and a Pi-compatible expansion port. Even with competition from the $9 Chip and $5 Raspberry Pi Zero, 2015’s biggest price/performance breakthrough among open-spec SBCs was arguably the $15 Orange Pi PC. Unlike the single-core Chip and Zero, the Orange Pi PC delivered the performance goods with a quad-core Cortex-A7 Allwinner H3 SoC, while offering more ports, including HDMI, Ethernet, quad USB, and Pi-compatible expansion. Now Shenzhen Xunlong has spun a similar, stripped down Orange Pi One variant for only $10 — or $13.77 if you want it shipped to the U.S.

Good leaders know what economics can't explain about open source

  • Story Type: News Story
Last week, I lucked into 30 minutes on the phone with one of my favorite people: author, speaker, blogger, and activist Cory Doctorow. Our conversation ran the gamut—from open source's role in building a better future, to the function of science fiction literature today, to Cory's preference for prose over code. At one point, Cory offered a rather succinct and evocative explanation of what motivates people to contribute to open source projects. And what he said got me thinking about open organizations.

Learn Linux, 101: Manage disk quotas

Learn to set and check disk quotas on your Linux filesystems to prevent individual users from using more space than allowed and to prevent whole filesystems from filling up unexpectedly. You can use the material in this tutorial to study for the LPI 101 exam for Linux system administrator certification, or just to learn about quotas.

IndiaHacks online code sprint includes month-long open source track

Open source software contributions often spring from passion—the passion to give back to the community, or simply the burning desire to create something new. The same passion that drives individual contributors also drives the team behind IndiaHacks to help develop the skills and networks of those individual contributors.
