There are a lot of reasons you might want to manually set your MAC address for your network card. I won’t ask you what your reason is.

To change this setting, we’ll need to edit the /etc/network/interfaces file. You can choose to use a different editor if you’d like.

Partition Image is a Linux/UNIX utility which saves partitions in many formats (see below) to an image file. The image file can be compressed in the GZIP/BZIP2 formats to save disk space, and split into multiple files to be copied on removable floppies (ZIP for example), … Partitions can be saved across the network since version 0.6.0.When using Partimage, the partitions must be unmounted.

Partimage is very useful in the following situations

First you can restore your linux partition if there is a problem (virus, file system errors, manipulation error) . When you have a problem, you just have to restore the partition, and after 10 minutes, you have the original partition. You can write the image to a CD-R if you don’t want the image to use hard-disk space.

This utility can be used to install many identical computers. For example, if you buy 50 PCs, with the same hardware, and you want to install the same linux systems on all 50 PCs, you will save a lot of time. Indeed, you just have to install on the first PC and create an image from it. For the 49 others, you can use the image file and Partition Image’s restore function.

If you want to create a system that is similar to a different system you have already set up, it can be difficult to remember each and every package you had installed.This method works best when you are exporting to and importing from the same distribution and, specifically, the same releasefor example, exporting from Ubuntu Dapper to Ubuntu Dapper or ubuntu edgy to ubuntu edgy.

Ubuntu uses the APT package management system which handles installed packages and their dependencies. If we can get a list of currently installed packages you can very easily duplicate exactly what you have installed now on your new machine.

Creating an optimal flexible layout (OFL) for a Xen cluster is more difficult than setting up a standalone box with just one environment running on it. This is especially true if you’re planning to let inexperienced users play on the boxes with escalated privileges, or if you are building your cluster to cope with disparate uses on the VMs. Databases, Web servers, and compute boxes can be difficult to manage in their own separate systems, and they’re much more difficult to manage in a Xen cluster if the sys admin of each VM is unaware of the load others are putting upon the architecture. The admins may not have sight of the other VMs’ hardware usage patterns and could encounter difficulty investigating bottlenecks and stoppages inside their own VMs caused by contention on the hypervisor’s other VMs. What is gained by using Xen in terms of flexibility and efficient use of hardware could easily be lost to complexity if initial plans of usage are poorly developed or inadequately tested. Gibbins shows how to set up a self-managed Xen cluster.

Red Hat, Fleet Commander, and Fedora 27

  • Fleet Commander Now Ready To Deploy Fedora & RHEL Desktops At Scale
    Fleet Commander is now declared "production ready" by the Red Hat developers working on this software project for easing the process of deploying and managing Fedora/Red Hat desktops across a large number of systems. Fleet Commander builds off the Cockpit web-based administration tools and FreeIPA for making it easier for system administrators to deploy Fedora and Red Hat based systems on a large scale within an organization.
  • A Look At The New Features For Fedora 27
    Fedora 27 is now under its final freeze for release in the next few weeks so here's a recap of the prominent changes coming to this next installment of the Red Hat sponsored Linux distribution. First and foremost, the Fedora Workstation 27 release is making use of GNOME 3.26 and its many exciting improvements, many of which upstream improvements were worked on by Fedora / Red Hat developers. GNOME 3.26 offers better Wayland support, some HiDPI improvements, initial built-in screencast / remote desktop support through Mutter, the reworked GNOME Control Center UI, many app improvements, and more as outlined in that aforelinked article.

Android: New Devices

  • ZTE launches crazy, foldable, dual-screened smartphone
    Budget Android company ZTE is launching what has to be its craziest-looking smartphone ever, the Axon M. The M looks like someone took a Nintendo DS, removed the controls, and stuck two big smartphone screens on each side. The Axon M is a whopping 12.1mm thick. A hinge runs along the long side of the phone, and it opens up, just like a Nintendo DS. On each side of the phone, you get a 5.2-inch, 1080p TFT LCD. Open the whole thing up, and when combined the screens sort of become a 6.75-inch, 8:9 aspect ratio, 1920x2160 display. I say "sort of" because of course there's a big seam down the middle.
  • Google's Pixel 2 Earns High Marks in Spite of Dull Design
    As Google's new Pixel 2 smartphones get ready to hit the shelves, reviews of the models have begun mushrooming online. While the new phones generally have received positive grades, many reviewers found the their design boring. "The Pixel 2 hardware is ho-hum," observed Patrick Moorhead, principal analyst at Moor Insights and Strategy.

  • Makerbot Labs Is One Step Toward Open Source 3D Printing
    3D printing feels a bit stuck. At the dawn of the 2010s, the device seemed destined to reimagine the creative process, putting the power of additive manufacturing within anyone's grasp. But trend has gone cold since reaching its popular zenith in 2013. While people continue to create amazing things with 3D printing, the "one in every household" promise has been put on temporary—or possibly permanent—hold. But the leader of the once great 3D printing revolution hasn't gone away quietly. In fact, it's done the opposite. Makerbot, the Brooklyn-based startup that sold its first printers back in 2009, is launching a brand new platform, Makerbot Labs, to help turn its 3D printing community into super-users, able to access parts of the printer that were otherwise inaccessible. Makerbot describes this new platform as a place, built for creators, who want to experiment with 3D printing but still have the bedrock of the platform to fall back on if need be.
  • IEEE to develop standard for automotive Ethernet of over 1 Gbps
