8 hours 28 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.

  • This open-source, multicloud serverless framework claims faster-than-bare-metal speed
    The move toward fast, serverless computing technology got a boost this month from Iguazio Systems Ltd. The data platform company (named from the Iguazu waterfalls in South America) announced the release of Nuclio, an open-source, multicloud serverless framework that claims faster-than-bare-metal speed. “We provide one platform, all the data services that Amazon has, or at least the ones that are interesting, serverless functions, which are 100 times faster, and a few more tricks that they don’t have,” said Yaron Haviv (pictured), founder and chief technology officer of Iguazio Systems. “We do fewer services, but each one kicks ass; each one is much faster and better engineered.”
  • CORD Says It’s the De Facto Choice for Edge Computing
    The Open Networking Foundation (ONF) today released 4.1 of its Central Office Re-architected as a Data Center (CORD) code. CORD has only been around as an independent project within ONF for about a year and a half, but with this release a couple of things have gelled for the project. First, it has merged its residential-CORD, mobile-CORD, and enterprise-CORD into one overarching project. Secondly, the ONF has realized CORD’s relevance in edge computing and edge cloud data centers.

  • AMD Moving Forward In Their RadeonSI Support For ARB_gl_spirv
    AMD open-source developer Nicolai Hähnle has spent the past few months working on the ARB_gl_spirv extension as mandated by OpenGL 4.6. Some of the prep work for supporting that extension has landed in Mesa 17.4-dev Git. ARB_gl_spirv is about bringing SPIR-V support to OpenGL drivers, the IR shared by Vulkan and OpenCL 2.1+. ARB_gl_spirv allows for loading SPIR-V modules into OpenGL programs and allows for GLSL to be a source language in creating SPIR-V modules. This is basically for creating better interoperability between OpenGL and Vulkan/SPIR-V.
  • Mesa Glthread Gets Adds Another Game, AMDGPU Winsys Gets Performance Workaround
    This week has started off to being another busy time in Mesa Git just ahead of the holidays. First up, Mount & Blade: Warband is the latest game to be white-listed by the Mesa glthread functionality for enabling OpenGL threading on this Steam Linux game. Mount & Blade: Warband was actually whitelisted back in July but then disabled a few days later as it turned out not to be working.
  • VESA Rolls Out DisplayHDR As Its Latest Standard
    VESA has rolled out DisplayHDR 1.0 as its newest standard. As implied by the name, the standard is in regards to specifying HDR (High Dynamic Range) quality for displays.
  • VC5 OpenGL & Vulkan Driver Advancing
    Broadcom developer Eric Anholt has offered an update on the state of the VC5 Gallium3D driver for OpenGL support as well as the work being done on the "BCMV" Vulkan driver. Additionally, the VC4 Gallium3D driver for existing Raspberry Pi devices continues to get better.
  • Initial Tessellation Shader Support For RadeonSI NIR
    The RadeonSI Gallium3D driver's NIR back-end is moving one step closer to feature parity with the existing OpenGL capabilities of this AMD GCN graphics driver. Timothy Arceri working for Valve has been focusing on the NIR back-end recently for RadeonSI. This NIR intermediate representation handling is being driven in order to add SPIR-V ingestion support to RadeonSI with code sharing for RADV's existing NIR-based infrastructure.

If You're Ready for Arch, ArchMerge Eases the Way

Newcomer ArchMerge Linux offers a big change for the better to those switching from the Debian Linux lineage to the Arch Linux infrastructure. ArchMerge Linux is a recent spinoff of ArchLabs Linux. I recently reviewed Archlabs and found it to be a step up from most Arch Linux offerings in terms of installation and usability. Arch Linux distros, in general, are notorious for their challenging installation and software management processes. ArchMerge Linux brings a few extra ingredients that make trying it well worth your while if you want to consider migrating to the Arch Linux platform. Still, no Arch Linux distro is a suitable starting point for Linux newcomers. That reality does not change with ArchMerge, although it helps ease the process considerably for those who are ready for it. Read more
