13 hours 40 min ago

You may need to step out of your comfort zone if you want to advance your career in an open organization. Taking a backseat approach and letting your managers drive you where they think you should go may not always get you to the best destination.

What is a blockchain smart contract?

Monday 11th of December 2017 08:03:00 AM

The first thing to know about blockchain smart contracts is they're not contracts, smart, or necessarily on a blockchain. They are, in fact, singularly ill-named.1 Let's address these issues in reverse order, and we should find out exactly what a smart contract actually is along the way. First, an introduction to what transactions are and things that aren't transactions.

How to use WeKan to manage your work

Monday 11th of December 2017 08:02:00 AM

Managing your work—figuring out which tasks to carry out and scheduling them—can be difficult. Not only are other things competing for your attention, there's only so much time in the day for you to do what you need or want to do.

There are any number of tools that you can use to help manage your workflow. You've probably used or test driven as many (or maybe even more) than I have. One that I find effective is WeKan.

Top 15 resources for learning JavaScript

Thursday 7th of December 2017 08:01:00 AM

HTML, cascading stylesheets (CSS), and JavaScript have experienced massive growth and evolution over the past two decades, which should come as no surprise given the ever-expanding role of the internet in our lives. JavaScript development has come a long way since the early 1990s and IBM's famous commercial depicting business' early recognition of the internet's significance. That commercial forever changed the role of the web developer.

Preparing your organization for a future built on blockchain

Thursday 7th of December 2017 08:00:00 AM

In the first part of this review of Blockchain Revolution by Don Tapscott and Alex Tapscott, I presented some of the ways the authors suggest blockchain technology will impact organizations. In particular, I examined the open organization principles (transparency, inclusivity, adaptability, collaboration, community) and the reasons we practice them (building a network of people dedicated to a purpose and sharing the same ethical standards, for example).

Running storage services on Kubernetes

Wednesday 6th of December 2017 08:06:00 AM

With the advent of containers, it's a good time to rethink storage completely. As applications now consist of volatile sets of loosely coupled microservices running in containers, ever-changing in scale, constantly being updated and re-deployed, and always evolving, the traditional mindset of serving storage and data services must change.

Is blockchain a security topic?

Wednesday 6th of December 2017 08:05:00 AM

Blockchains are big news at the moment. There are conferences, startups, exhibitions, open source projects (in fact, pretty much all of the blockchain stuff going on out there is open source—look at Ethereum, Zcash, and Bitcoin as examples); all we need now are hipster-run blockchain-themed cafés.1 If you're looking for an initial overview, you could do worse than the Wikipedia entry—but that's not the aim of this post.

Getting started with Turtl, an open source alternative to Evernote

Wednesday 6th of December 2017 08:04:00 AM

Just about everyone I know takes notes, and many people use an online note-taking application like Evernote, Simplenote, or Google Keep. Those are all good tools, but you have to wonder about the security and privacy of your information—especially in light of Evernote's privacy flip-flop of 2016. If you want more control over your notes and your data, you really need to turn to an open source tool.

10 must-read DevOps resources

Wednesday 6th of December 2017 08:00:00 AM

Continuous learning is a key component of DevOps and digital transformation. If you are not learning from your day-to-day operations, your operational mindset will never change. If you don't put effort into pushing the limits of each team member's mind, your team will never reach its fullest potential. To quote Andrew Clay Shafer: "You are either building a learning organization, or you will be losing to someone who is."

7 rules for avoiding documentation pitfalls

Tuesday 5th of December 2017 08:04:00 AM

English serves as lingua franca in the open source community. To reduce translation costs, many teams have switched to English as the source language for their documentation. But surprisingly, writing in English for an international audience does not necessarily put native English speakers in a better position. On the contrary, they tend to forget that the document's language might not be the audience's first language.

  • Juniper Networks Reinforces Longstanding Commitment to Open Source by Moving OpenContrail's Codebase to the Linux Foundation
    Juniper Networks (NYSE: JNPR), an industry leader in automated, scalable and secure networks, today further bolstered its support for open standards during its annual NXTWORK user conference, by announcing its intent to move the codebase for OpenContrail™, an open-source network virtualization platform for the cloud, to the Linux Foundation. Juniper first released its Juniper® Contrail® products as open sourced in 2013 and built a vibrant user and developer community around this project. Earlier this year, Juniper expanded the project's governance, creating an even more open, community-led effort to strengthen the project for its next growth phase. Adding OpenContrail's codebase to the Linux Foundation's networking projects will further its objective to grow the use of open source platforms in cloud ecosystems.
  • Hyperledger Hub Supports Open Source Blockchain Development
    Hyperledger is a global blockchain collaboration hub created and hosted by nonprofit The Linux Foundation. Its members are leaders in finance, banking, the Internet of Things, supply chains, manufacturing and technology. Now two years in, Hyperledger compares closely to the Ethereum Enterprise Alliance. Hyperledger is a hub for communities of software developers building blockchain frameworks and platforms. These developers, on the other hand, are a mix of individuals and teams from organizations around the world.
  • Linux Foundation Continues to Emphasize Diversity and Inclusiveness at Events
    This has been a pivotal year for Linux Foundation events. Our largest gatherings, which include Open Source Summit, Embedded Linux Conference, KubeCon + CloudNativeCon, Open Networking Summit, and Cloud Foundry Summit, attracted a combined 25,000 people from 4,500 different organizations globally. Attendance was up 25 percent over 2016. Linux Foundation events are often the only time that developers, maintainers, and other pros who contribute to Linux and other critical open source projects — like AGL, Kubernetes and Hyperledger to name a few — get together in person. Face-to-face meetings are crucial because they speed collaboration, engagement and innovation, improving the sustainability of projects over time.

  • Huawei Collaborated with the Developers of Phoenix OS for the Mate 10’s Easy Projection Feature
    Though the company has virtually no presence in the United States, Huawei is a top 3 smartphone manufacturer in the world. Its subsidiary, Honor, aims to penetrate the Indian market with budget smartphones. Elsewhere, Huawei recently launched the Huawei Mate 10 and Mate 10 Pro in several markets around the world, and rumors have it the device will launch in the United States as well. Apart from the AI features powered by the company’s HiSilicon Kirin 970 SoC, one of the company’s most publicized features is Easy Projection. While not as powerful as Samsung DeX, it brings a desktop OS-like experience without needing to purchase an expensive accessory. Huawei is pushing the feature on its flagship devices, though there’s something about Easy Projection that hasn’t really been mentioned in the press yet. Behind Huawei’s Easy Projection feature is a relatively unheard of player—Beijing Chaozhuo Technology, developers of Phoenix OS.

From this initial commit, since I found this data quite cool, I improved the support a bit (auto-detection of the variants and special-casing in particular, as well as making an API for scripts). So what is HGT? That’s topography data basically just containing elevation in meters of various landscape (HGT stands for “height“), gathered by the Shuttle Radar Topography Mission (SRTM) run by various space agencies (NASA, National Geospatial-Intelligence Agency, German and Italian space agencies…).
  • What You Need To Know About The Intel Management Engine
    Over the last decade, Intel has been including a tiny little microcontroller inside their CPUs. This microcontroller is connected to everything, and can shuttle data between your hard drive and your network adapter. It’s always on, even when the rest of your computer is off, and with the right software, you can wake it up over a network connection. Parts of this spy chip were included in the silicon at the behest of the NSA. In short, if you were designing a piece of hardware to spy on everyone using an Intel-branded computer, you would come up with something like the Intel Managment Engine. Last week, researchers [Mark Ermolov] and [Maxim Goryachy] presented an exploit at BlackHat Europe allowing for arbitrary code execution on the Intel ME platform. This is only a local attack, one that requires physical access to a machine. The cat is out of the bag, though, and this is the exploit we’ve all been expecting. This is the exploit that forces Intel and OEMs to consider the security implications of the Intel Management Engine. What does this actually mean?
