welcome to issue 191 of linux user & developer

Welcome to the UK and North America’s favourite Linux and open source magazine. It’s been another fascinating month in the open source world. Of course, Ubuntu 18.04 LTS has landed, but we’ve also seen strong open source advocate Nextcloud snag a seven-figure deal to supply the German federal government with a private Bundescloud for 300,000 civil servants. Then Microsoft floored a lot of people by revealing an entirely Linux-based OS for a microcontroller it is touting for IoT devices. The Linux Foundation’s Jim Zemlin describes Microsoft’s Linux usage as the “new normal” – and we shouldn’t be surprised, plenty of companies now use Linux and FOSS when it makes money and practical sense. To that end we turn to our main feature this month, where we’ll show you how to use…

facebook investigated, apologises for breach of trust

The headline-grabbing Cambridge Analytica scandal has hit users of all platforms, highlighting once again the importance of openness when it comes to the treatment of personal data by online services such as social networks. Keeping in mind that just 270,000 people used the ‘thisisyourdigitallife’ app, it is staggering that data for 50 million people (including friends and family of the app users) was then farmed, and used for political-campaign targeting in a process that began in 2014. Mark Zuckerberg, as ever doing his best to distance Facebook from scandal, took the time to issue a full-page apology in several newspapers. In it, the billionaire CEO apologises for the 2014 breach of trust “that leaked Facebook data of millions of people” and reveals that along with limiting data to third-parties, Facebook is…

gnome shell memory leak bug discovered

Memory leaks have most famously affected browsers in the past, so the idea that a desktop environment should be subject to one of these resource-draining bugs is surprising. But GNOME Shell 3.26.2, which is most commonly found in Ubuntu 17.10, has a leak that has been spotted by a number of users, and reported as a bug. It appears the bug is triggered by performing actions with an associated animation. Things such as opening the overview, minimising windows or simply switching them can result in a system that grinds to a halt after a few hours of use, hitting productivity. That’s not ideal, especially if you’re using a laptop; you can’t just reboot your way out of trouble if the added load has also drained your battery. Once triggered, RAM use increases…

steam machines on the way out?

Once touted as the brave new future for PC gaming, Steam Machines – console-like PCs running the Linux-based SteamOS and produced by Alienware, Asus and others – somehow went largely unnoticed. Perhaps it was SteamOS’s lack of traction, or perhaps Steam’s own Link game-streaming boxes nixed the idea of Steam Machines before it could really get going. “It’s true Steam Machines aren’t exactly flying off the shelves” Whatever the case, Valve is no longer promoting Steam-powered PCs via the Hardware link on the Steam website or its desktop client – although the page itself has not been removed. When its “routine cleanup” eventually morphed into an ‘anti-Steam Machines’ conspiracy theory, Valve opted to address concerns. Overall, it appears to be a general change of strategy, although the Steam Machines are still available; they…

intel discontinues its graphics updater

As Linux distributions develop and improve, it isn’t unusual for third-party tools and software to adapt. The Intel Graphics Update Tool is a good example. Released in 2013 to give Linux users a safe and reliable way to install and upgrade to stable drivers and firmware on Intel graphics hardware, five years down the line the software has become largely redundant. The Intel graphics blog announced on 8 March that “users will notice Fedora 27 and Ubuntu 17.10 and beyond are very current. Therefore, we are discontinuing the Update Tool as of version 2.0.6. The final version 2.0.6 of the update tool was targeted specifically at both Ubuntu 17.04 and Fedora 26. Earlier revisions for those Linux distributions are no longer being supported.” Previously known as the Intel Graphics Installer for Linux,…
