Two boxes have been setup , each one having 2 NICs (enp2s0,enp5s1) for Controller && Compute Nodes setup. Before running `packstack --answer-file=TwoNodeVXLAN.txt` SELINUX set to permissive on both nodes.Both enp5s1's assigned IPs and set to promiscuous mode (192.168.0.127, 192.168.0.137 ). Services firewalld and NetworkManager disabled, IPv4 firewall with iptables and service network are enabled and running. Packstack is bind to public IP of interface enp2s0 192.169.1.127, Compute Node is 192.169.1.137 ( view answer-file ).

Tiny Raspberry Pi-compatible SBC targets wearables

Wednesday 30th of July 2014 12:06:54 AM
Hardkernel launched a $30, 60 x 36mm Raspberry-Pi compatible “Odroid-W” wearables oriented SBC, adding eMMC, ADC, RTC, a fuel gauge, and step converters. Hardkernel’s Odroid project developed the Odroid-W (Odroid-Wearable) for a partner’s Internet of Things prototyping platform, after first considering and dismissing its quad-core Odroid-U3 single board computer. The Odroid-U3, which was rated as the third most popular Linux hacker SBC in our recent survey, used too much power for use as an IoT and wearables platform. The Raspberry Pi was more power efficient, but too large. No doubt, RPi compatibility also had its attractions, as the project ended up building its own Raspberry Pi pseudo-clone implemented on a COM (computer-on-module) style form factor.

Who's using Docker?

Tuesday 29th of July 2014 11:09:43 PM
I've spent the last couple of months working an internship for The Linux Foundation, doing research on new developments and adoption trends in the open source industry. If you have spent any amount of time reading about open source over the last year, you have probably heard about Docker; a lot of people are talking about it these days and the impact it's going to have on virtualization and DevOps.read more

6 open source tools for data journalism

Tuesday 29th of July 2014 04:29:26 PM
When I was in journalism school back in the late 1980s, gathering data for a story usually involved hours of poring over printed documents or microfiche.A lot has changed since then. While printed resources are still useful, more and more information is available to journalists on the web. That’s helped fuel a boom in what’s come to be known as data journalism. At its most basic, data journalism is the act of finding and telling stories using data—like census data, crime statistics, demographics, and more.read more

Hybrid RAID 1 (Mirror) of RAM drive & SATA HDD Using LVM with LUKS [and systemd unit file] on Fedora Linux

Tuesday 29th of July 2014 03:32:15 PM
Hybrid RAID 1 (Mirror) of RAM drive & SATA HDD Using LVM with LUKS [and systemd unit file] on Fedora LinuxThe IT industry has a continual balance between security and usability. Within this balance, performance usually affects usability. In the realm of protecting "Data at Rest" (i.e. encryption) one may find three factors affecting performance, and therefore usabilty: The harddrive, CPU and RAM. Of these, the harddrive will always prove to be a bottleneck (yes, even with an SDD).Free Software has a rather elegant solution for protecting Data at Rest, called Linux Unified Key Setup (LUKS). In the spirit of "Freedom 0: The freedom to run the program for any purpose." please enjoy my contribution to our collective knowledgebase of a solution to the fascinating problem of "how can we speed up encyption"?

Cloudy CoreOS Linux distro declares itself production-ready

Tuesday 29th of July 2014 01:37:53 PM
The developers behind the stripped-down CoreOS Linux distribution have pushed version 367.1.0 to the Stable release channel, marking the first time the project has delivered a production-ready release. Unlike other Linux distros, CoreOS is a minimal OS that ships each new version as a single unit, rather than updating individual software packages. Updates are pushed to users via "channels," similar to how web browser vendors deliver their releases.

Windows comes to Raspberry Pi-style board in Microsoft/Intel project

Tuesday 29th of July 2014 06:57:36 AM
Even Microsoft wants a piece of the development board market made famous by Arduino and Raspberry Pi...At $300, Sharks Cove is significantly more expensive than non-Windows alternatives. Hobbyists will probably be more inclined to buy the ARM-based Raspberry Pi, which is just $35, or the $55 BeagleBone Black. Even the Intel-based MinnowBoard, which is compatible with Linux and Android, starts at just $99. CircuitCo also makes both the BeagleBone Black and MinnowBoard.
