Virtualization With VirtualBox 3.1.x On A Headless Mandriva 2010.0 Server

Filed under
MDV
HowTos

This guide explains how you can run virtual machines with Sun VirtualBox 3.1.x on a headless Mandriva 2010.0 server. Normally you use the VirtualBox GUI to manage your virtual machines, but a server does not have a desktop environment. Fortunately, VirtualBox comes with a tool called VBoxHeadless that allows you to connect to the virtual machines over a remote desktop connection, so there's no need for the VirtualBox GUI.

HowTos

This data includes information about the position of the camera when the image was taken... However, some image programs use this data to rotate the image when displaying it while others don't, leaving the user to face inconsistent behaviour. This can be fixed.

Creating An NFS-Like Standalone Storage Server With GlusterFS On CentOS 5.4

Filed under
HowTos

This tutorial shows how to set up a standalone storage server on CentOS 5.4. Instead of NFS, I will use GlusterFS here. The client system will be able to access the storage as if it was a local filesystem. GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. Storage bricks can be made of any commodity hardware such as x86_64 servers with SATA-II RAID and Infiniband HBA.

BeagleBone based 3D printer focuses on ease of use

The “Voladd 3D Printer” features a Linux-driven BeagleBone SBC that connects to a cloud-based sharing site, plus a unique cartridge and cooling system. San Sebastián, Spain based Voladd has won Kickstarter funding for a Voladd 3D printer that runs Debian Linux on a BeagleBone Black single board computer. Like several other Linux-based printers we’ve seen (see farther below) the Voladd connects to a cloud service, and does not require an attached computer. The printer stands out with its mobile app remote control, as well as a streamlined cloud interface that lets you download one of thousands of free designs in 25 categories and share designs and printer access with others. Kickstarter pricing starts with early bird packages of 499 Euros ($591), with shipments due in December. Read more

OSS: Open Source Initiative, Open Xchange, OpenOffice, MakerBot

  • Open Source Initiative Welcomes Cumulus Networks As Premium Sponsor
    The Open Source Initiative® (OSI), the internationally recognized home of the open source software movement working to raise awareness and adoption of open source software, announced today the generous sponsorship of Cumulus Networks. Cumulus joins OSI's growing community of corporations that recognize the importance of not only investing in open source software projects and development, but also building a diverse ecosystem that promotes collaboration, enables innovation, and ensures quality. Cumulus Networks has a strong tradition of internally-driven development of original open source software, including most notably, contributions to the Linux kernel that complete the data center feature set for Linux such as Virtual Routing and Forwarding (VRF), MPLS, MLAG infrastructure, multicast routing features, etc. Cumulus' most recent open source effort is FRRouting, co-developed by a group of contributing companies in the open networking space, to enhance routing protocols. Cumulus Networks has also been a key driving member of the Open Network Install Environment (ONIE) with contributions to the Open Compute Project, Prescriptive Topology Manager--which simplifies the deployment of large L3 networks--and ifupdown2, a rewrite of Debian's tool for configuring networks that greatly simplifies large, complicated networking configurations.
  • Let's dig into how open source could KO the Silicon Valley chat silos
    There's never been a better opportunity for the world to start untangling itself from the giant Silicon Valley data harvesters than now. Last week, we revealed a plan to embed open-source chat into three quarters of the world's IMAP servers. And this may be an important development. Maybe. Google, Yahoo!, Apple and Microsoft handle around half the world's email, some 2.5 billion users, while open-source IMAP servers handle the rest, around 2.5-3 billion. Of these the Dovecot open-source server, part of the German business Open Xchange, is installed on 75 per cent of boxes. Quietly drop IM into the mix, and you've given the world a reason to leave WhatsApp.
  • Open source, agility powering enterprise IT
    Looking back over the past decade, history has certainly demonstrated that trying to predict the pace and nature of technology development is a near impossible task, writes Quentin Barnard, lead architect at redPanda Software. While analysts, business leaders and policymakers have certainly made wise predictions, businesses and individuals have to remain agile, responsive and open-minded to a wide possibility of outcomes and developments. It is also helpful, however, to reflect on key trends that have emerged in recent times — and to use this information to prepare for the years ahead. For software developers and development houses, several prominent themes emerged in 2017.

  • MakerBot Labs: new experimental 3D printing platform is MakerBot's olive branch to open source community
    New York 3D printing company MakerBot has launched MakerBot Labs, an experimental platform with open APIs, custom print modes, and an online resource-sharing site. The platform purportedly allows users to “push the limits” of 3D printing.
  • MakerBot attempts to embrace the open-source community with its new Labs platform
    The topic of open source has been a touchy one for MakerBot over the past decade. The one-time 3D-printing darling was the subject of some serious smack talk among the maker community when it stopped disclosing machine design in 2012 — a departure from the company’s roots as in the open-source Rep-Rap community. Announced this week, MakerBot Labs doesn’t mark a full return to those roots, but it does find the company carving out a niche for the DIY community that was once a driving force in its rapid growth. “I understand the history,” CEO Nadav Goshen told TechCrunch during a phone call this week, “This is one step in the direction. It’s a step to understand that there are limitations to openness. Openness for us doesn’t mean we have to compromise on quality or ease of use. We’re trying to take responsibility for both.”
