How Twitter Avoids the Microservice Version of “Works on My Machine”

Wednesday 17th of August 2016 02:03:07 PM

Apache Mesos and Apache Aurora initially helped Twitter engineers to implement more sophisticated DevOps processes and streamline tooling, says software engineer David McLaughlin. But over time a whole new class of bespoke tooling emerged to manage deployment across multiple availability zones as the number of microservices grew.

Flatpak: A Containerized Approach to Developing Linux Applications

Tuesday 16th of August 2016 03:00:29 PM

Containers are becoming increasingly popular in the enterprise world, which has come to realize that containers not only solve many problems, but also bring agility, scalability, and other benefits to the IT infrastructure. This idea is now trickling down to the desktop world.

Cloud-Based Systems Can Accelerate the Benefits of Big Data

Tuesday 16th of August 2016 02:30:34 PM

Cloud platforms enable enterprise companies to begin their big data journey much faster than on-premises systems because of centralization of control and administration, massive geographic reach, and because of the elasticity of Infrastructure-as-a-Service (IaaS) that allows you to create just the right amount of computing power on the fly, according to Ashish Thusoo, co-founder and CEO of Qubole and former head of Facebook’s big data initiatives, speaking at the Apache Big Data conference in May.

IBM Watson Researchers Share Tips for Serverless Computing on Mesos

Monday 15th of August 2016 05:50:08 PM

Serverless computing is the latest trend in cloud computing brought about by the enterprise shift to containers and microservices.

Serverless computing platforms promise new capabilities that make writing scalable microservices easier and more cost effective, say IBM software engineer Diana Arroyo and research staff member Alek Slominski.

Testing Network Connectivity for Applications in Containers

Monday 15th of August 2016 03:00:30 PM

Testing applications is a critical part of software development as illustrated by the rise of continuous integration and automated testing. In his upcoming LinuxCon + ContainerCon talk -- Testing Applications with Traffic Control in Containers -- Alban Crequy will focus on one area of testing that is difficult to automate: poor network connectivity. He will describe a testing approach which emulates network connectivity and which integrates existing Linux kernel features into higher level tools such as Kubernetes and Weave Scope.

Virtual Machine Introspection: A Security Innovation With New Commercial Applications

Thursday 11th of August 2016 01:00:20 PM

A few weeks ago, Citrix and Bitdefender launched XenServer 7 and Bitdefender Hypervisor Introspection, which together compose the first commercial application of the Xen Project Hypervisor’s Virtual Machine Introspection (VMI) infrastructure. In this article, we will cover why this technology is revolutionary and how members of the Xen Project Community and open source projects that were early adopters of VMI (most notably LibVMI and DRAKVUF) collaborated to enable this technology.

Be Cautious With Containers Says FutureAdvisor’s DevOps Director

Wednesday 10th of August 2016 03:00:00 PM

Docker and microservices-based architectures have expanded our horizons with respect to how the industry builds and supports applications at scale, says Corey Quinn, Director of DevOps at FutureAdvisor and an early developer behind SaltStack. Nonetheless, Quinn, in his LinuxCon and ContainerCon North America talk — called “Heresy in the Church of Docker” — will preach caution and present an alternative view of the containerization craze.

  • MPlayer-Based MPV 0.20.0 Video Player Released with New Options and Commands
    The popular, open-source, and cross-platform MPV video player software received a new update, version 0.20.0, which comes only two weeks after the previous 0.19.0 maintenance release. MPV 0.20.0 is not a major update, and, according to the release notes, it only implements a couple of new options and commands, such as "--video-unscaled=downscale-big" for changing the aspect ratio. Additionally, the MPlayer-based video playback application also gets the "--image-display-duration" option for controlling the duration of image display, and a new "dcomposition" flag for controlling DirectComposition.

  • Report: If DOD Doesn't Embrace Open Source, It'll 'Be Left Behind'
    Unless the Defense Department and its military components levy increased importance on software development, they risk losing military technical superiority, according to a new report from the Center for a New American Security. In the report, the Washington, D.C.-based bipartisan think tank argues the Pentagon, which for years has relied heavily on proprietary software systems, “must actively embrace open source software” and buck the status quo. Currently, DOD uses open source software “infrequently and on an ad hoc basis,” unlike tech companies like Google, Amazon and Facebook that wouldn’t exist without open source software.
  • The Honey Trap of Copy/Pasting Open Source Code
    I couldn’t agree more with Bill Sourour’s article ‘Copy.Paste.Code?’ which says that copying and pasting code snippets from sources like Google and StackOverflow is fine as long as you understand how they work. However, the same logic can’t be applied to open source code. When I started open source coding at the tender age of fourteen, I was none the wiser to the pitfalls of copy/pasting open source code. I took it for granted that if a particular snippet performed my desired function, I could just insert it into my code, revelling in the fact that I'd just gotten one step closer to getting my software up and running. Yet, since then, through much trial and error, I’ve learned a thing or two about how to use open source code effectively.
  • Affordable, Open Source, 3D Printable CNC Machine is Now on Kickstarter
    The appeals of Kickstarter campaigns are many. There are the rewards for backers, frequently taking the form of either deep discounts on the final product or unusual items that can’t be found anywhere else. Pledging to support any crowdfunding campaign is a gamble, but it’s an exciting gamble; just browsing Kickstarter is pretty exciting, in fact, especially in the technological categories. Inventive individuals and startups offer new twists on machines like 3D printers and CNC machines – often for much less cost than others on the market.
  • Open Standards and Open Source
    Much has changed in the telecommunications industry in the years since Standards Development Organization (SDOs) such as 3GPP, ITU and OMA were formed. In the early days of telecom and the Internet, as fundamental technology was being invented, it was imperative for the growth of the new markets that standards were established prior to large-scale deployment of technology and related services. The process for development of these standards followed a traditional "waterfall" approach, which helped to harmonize (sometimes competing) pre-standard technical solutions to market needs.

  • The Voicemail Scammers Never Got Past Our OpenBSD Greylisting
    We usually don't see much of the scammy spam and malware. But that one time we went looking for them, we found a campaign where our OpenBSD greylisting setup was 100% effective in stopping the miscreants' messages. During August 23rd to August 24th 2016, a spam campaign was executed with what appears to have been a ransomware payload. I had not noticed anything particularly unusual about the bsdly.net and friends setup that morning, but then Xavier Mertens' post at isc.sans.edu Voice Message Notifications Deliver Ransomware caught my attention in the tweetstream, and I decided to have a look.
