The Spectre And Meltdown Server Tax Bill

  • The Spectre And Meltdown Server Tax Bill

    Much has been written about the nature of the Meltdown and Spectre threats, which leverage the speculative execution features of modern processors to give user-level applications access to operating system kernel memory. This is obviously a very big problem. Chip suppliers and operating system and hypervisor makers have known about these exploits since last June, and have been working behind the scenes to provide corrective countermeasures to block them. The idea was to wait until January 9 to have all the fixes lined up in the industry and then tell the world about the exploits. But rumors about the speculative execution threats forced the hands of the industry, and last week Google put out a notice about the bugs and then followed up with details about how it has fixed them in its own code for its own systems.

What Stratis learned from ZFS, Btrfs, and Linux Volume Manager

The reasons vary. First, let's consider ZFS. Originally developed by Sun Microsystems for Solaris (now owned by Oracle), ZFS has been ported to Linux. However, its CDDL-licensed code cannot be merged into the GPL-licensed Linux source tree. Whether CDDL and GPLv2 are truly incompatible is a subject for debate, but the uncertainty is enough to make enterprise Linux vendors unwilling to adopt and support it. Btrfs is also well-established and has no licensing issues. For years it was the "Chosen One" for many users, but it just hasn't yet gotten to where it needs to be in terms of stability and features. So, fuelled by a desire to improve the status quo and frustration with existing options, Stratis was conceived. Read more

How to Upgrade from Ubuntu 17.10 or Ubuntu 16.04 LTS to Ubuntu 18.04 LTS

Before we go through the upgrade process in more detail, there are a few things you should know. First and foremost, make sure you have a recent backup of your most important files on an external drive, do it now! Second of all, if you're upgrading from Ubuntu 16.04 LTS, you'll have to deal with some major desktop changes if you use Unity. Ubuntu 16.04 LTS (Xenial Xerus) uses the Unity desktop environment by default, but Ubuntu 18.04 LTS uses the GNOME desktop environment with a highly customized interface to make it look like Unity, which Canonical said it won't be removed during the upgrade process and will remain available as an alternative if you still want to use it.

Best Linux apps of 2018

While everyone knows that most Linux distributions (distros) are free to download, not everybody is aware that you also have access to thousands of cost-free applications through your operating system’s package manager. Many of the more user-friendly distros will come with a selection of software preinstalled to help you get started, but there are many more apps out in the wild, under continuous development.
