Rumors of COBOL's demise have been greatly exaggerated: Meet GnuCOBOL

Sunday 19th of June 2016 10:01:50 PM
A recent article on Slashdot points out with some chagrin that the Department of Homeland Security and Department of Veterans Affairs in the United States still use COBOL, originally invented in 1959, based on work by the late Rear Admiral Grace Hopper. The implication is—and has been for some years in the IT community—that COBOL is a completely dead language. Not so!read more

Snaps - A Good Way to Test the Latest Apps

Sunday 19th of June 2016 12:17:45 PM
As of the latest Ubuntu 16.04 LTS release, the core program 'snapd' is included out of the box, allowing you to install 'Snaps' right away.Now, as one would expect, there is and will continue to be some controversy about the nature of a new software packaging system and it's potential uses in the future. I don't really wish to go too much into that, as there is plenty of discussions out there in the Linux side of the interwebs, other than the purpose of this article is to state that if nothing else, Snaps are a good way to test different versions (stable, bleeding edge etc) of software.

Sunday 19th of June 2016 06:34:39 AM
This one was so easy to predict. For the past couple of decades, completely clueless US politicians and bureaucrats (and tech company execs) have been screaming about how China "doesn't respect" our intellectual property. They demanded that China "get more serious" about patents and respecting IP. And for nearly a decade we've been warning those people to be careful what you wish for.

OSS in the Back End

  • Open Source NFV Part Four: Open Source MANO
    Defined in ETSI ISG NFV architecture, MANO (Management and Network Orchestration) is a layer — a combination of multiple functional entities — that manages and orchestrates the cloud infrastructure, resources and services. It is comprised of, mainly, three different entities — NFV Orchestrator, VNF Manager and Virtual Infrastructure Manager (VIM). The figure below highlights the MANO part of the ETSI NFV architecture.
  • After the hype: Where containers make sense for IT organizations
    Container software and its related technologies are on fire, winning the hearts and minds of thousands of developers and catching the attention of hundreds of enterprises, as evidenced by the huge number of attendees at this week’s DockerCon 2016 event. The big tech companies are going all in. Google, IBM, Microsoft and many others were out in full force at DockerCon, scrambling to demonstrate how they’re investing in and supporting containers. Recent surveys indicate that container adoption is surging, with legions of users reporting they’re ready to take the next step and move from testing to production. Such is the popularity of containers that SiliconANGLE founder and theCUBE host John Furrier was prompted to proclaim that, thanks to containers, “DevOps is now mainstream.” That will change the game for those who invest in containers while causing “a world of hurt” for those who have yet to adapt, Furrier said.
  • Is Apstra SDN? Same idea, different angle
    The company’s product, called Apstra Operating System (AOS), takes policies based on the enterprise’s intent and automatically translates them into settings on network devices from multiple vendors. When the IT department wants to add a new component to the data center, AOS is designed to figure out what needed changes would flow from that addition and carry them out. The distributed OS is vendor-agnostic. It will work with devices from Cisco Systems, Hewlett Packard Enterprise, Juniper Networks, Cumulus Networks, the Open Compute Project and others.

  • A Seamless Monitoring System for Apache Mesos Clusters
  • All Marathons Need a Runner. Introducing Pheidippides
    Activision Publishing, a computer games publisher, uses a Mesos-based platform to manage vast quantities of data collected from players to automate much of the gameplay behavior. To address a critical configuration management problem, James Humphrey and John Dennison built a rather elegant solution that puts all configurations in a single place, and named it Pheidippides.
  • New Tools and Techniques for Managing and Monitoring Mesos
    The platform includes a large number of tools including Logstash, Elasticsearch, InfluxDB, and Kibana.
  • BlueData Can Run Hadoop on AWS, Leave Data on Premises
    We've been watching the Big Data space pick up momentum this year, and Big Data as a Service is one of the most interesting new branches of this trend to follow. In a new development in this space, BlueData, provider of a leading Big-Data-as-a-Service software platform, has announced that the enterprise edition of its BlueData EPIC software will run on Amazon Web Services (AWS) and other public clouds. Essentially, users can now run their cloud and computing applications and services in an Amazon Web Services (AWS) instance while keeping data on-premises, which is required for some companies in the European Union.

Industrial SBC builds on Raspberry Pi Compute Module

On Kickstarter, a “MyPi” industrial SBC using the RPi Compute Module offers a mini-PCIe slot, serial port, wide-range power, and modular expansion. You might wonder why in 2016 someone would introduce a sandwich-style single board computer built around the aging, ARM11 based COM version of the original Raspberry Pi, the Raspberry Pi Compute Module. First off, there are still plenty of industrial applications that don’t need much CPU horsepower, and second, the Compute Module is still the only COM based on Raspberry Pi hardware, although the cheaper, somewhat COM-like Raspberry Pi Zero, which has the same 700MHz processor, comes close.
