kmandla.wordpress: A long time ago I was messing with xscreensaver and found you could paint the root window — the desktop — with a screensaver, and use it like an animated wallpaper image. I was experimenting with them on the Thinkpad today, and this time I set popsquares to use Tango colors.

Making a backup reminder script

HowTos

linux.com: I like to back up the data on my laptop computer as often as possible, just in case I have trouble with it. I have some large files on the laptop that prevent me from scheduling an Internet backup to my home machine, so I have written a script that reminds me to periodically plug in an external USB drive; then upon clicking continue, the reminder script runs my custom backup script.

Creating dynamic swap space

Filed under
HowTos

debian administration: When a GNU/Linux machine runs out of physical memory it will start to use any configured swap-space. This is usually a sign of trouble as swap files and partitions are significantly slower to access than physical memory, however having some swap is generally better than having none at all. Using a dynamic system can ease the maintainance of this size.

Automated user management with Expect

linux.com: At the large school in Mexico where I'm employed as a system manager, I proposed (and got) a Linux server to replace an old Windows 2000 file server and domain controller for the alumni. I then was faced with the task of adding 3,000 users to this new CentOS 5 server. I wasn't about to add thousands of users and their passwords one by one.

  • Open Source NFV Part Four: Open Source MANO

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.

  • BlueData Can Run Hadoop on AWS, Leave Data on Premises

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.
