Run a Linux server farm for nix

Filed under
Linux

One great thing about Linux is its rock-solid nature even when you load it up with as many daemons and services as you like. Yet, often “best practice” dictates you separate out some apps across a couple of servers or at the very least provide a safe development environment which is distinct from your production environment.

Or you might be about to make a serious change in your environment and need a safe way of making a complete backup with instantaneous restore if need be. Or maybe you want to try out different Linux distros without reformatting, but Live CDs don’t let you customise enough and USB sticks are too slow.

The solution to all these problems and more is virtualisation and the key players we check out here are VMWare, XenSource and Microsoft Virtual PC.

  • Smartphones with fingerprint scanners under screen to hit market this year
    The majority of fingerprint scanners can be found either on the back of a smartphone or on the front, embedded in the home button. But it looks like that status quo is soon about to change. According to a report from The Investor, CrucialTec, a manufacturer of fingerprint modules based in South Korea, will launch its on-screen fingerprint scanning solution that allows you to unlock your device by placing a finger on the screen sometime this year. This means that we can expect to see the first smartphones featuring the new fingerprint technology hit the market in 2017. Unfortunately, CrucialTec did not reveal an exact time frame or the smartphone manufacturers it is currently working with.

    We reported earlier that Canonical published multiple security advisories to inform Ubuntu users about the availability of new kernel updates that patch several flaws discovered recently by various developers. We've already told you about the issues that are affecting Ubuntu 16.04 LTS and Ubuntu 16.04.1 LTS (Xenial Xerus) users, so check that article to see how you can update your systems is you're still using the Linux 4.4 LTS kernel.
