welcome to issue 190 of linux user & developer

Welcome to the UK and North America’s favourite Linux and FOSS magazine. We’re looking back somewhat wistfully at this past month as we reflect on the passing of Professor Stephen Hawking, a giant in the field of theoretical physics and ‘most intelligent guest star on The Simpsons’. On the flipside, we had the pleasant surprise of a Pi-shaped blip appear on our radar (see p86 for our Raspberry Pi B+ review). It seemed clear that 2018 was to be bereft of new Pis, so we’d consoled ourselves with a big, fat Electronics for Pi Hackers feature (p18) on building circuits and ways to interface with the Pis we did have. But the new Pi 3 B+ is a great addition with its appealing networking charms, and we’ve already pencilled in tutorials…

purism ups the ante for laptop security

Purism’s continued focus on producing the most secure, private laptops has resulted in a new partnership with eclectic hacker Trammell Hudson. His Heads security firmware has been integrated into Trusted Platform Module chips, delivering enhanced protection for users of Purism’s Linux hardware. The result of 12 months’ development, the enhancement required some hardware changes, coreboot modifications, and of course operating system updates. As Purism CEO Todd Weaver noted: “Your privacy is dependent on your freedom. We believe that having true privacy means your computer and data should be under your control, and not controlled by big tech corporations.” Librem laptop users can now take control of the secure boot process, using Heads to establish if software has been tampered with at the boot level. “By activating Heads in our TPM-enabled coreboot by default…

canonical installs data-collection tool in ubuntu

Paranoia has struck the Ubuntu community over the past few weeks following news that a data-collection tool has been placed in the Ubuntu 18.04 LTS installer by Canonical. While this only collects system hardware information, rather than the far more intrusive usage data collected by Microsoft in Windows 10, the decision has been met with controversy. In an announcement to the Ubuntu development mailing list, Canonical’s Will Cooke explained that the data collected was not meant to be intrusive. “Information from the installation would be sent over HTTPS to a service run by Canonical’s IS team. This would be saved to disk and sent on first boot once there is a network connection. The file containing this data would be available for the user to inspect. The results of this data would…

five ubuntu 18.04 lts features

1 New default apps Several new default apps are being included with Ubuntu (or made available at the setup screen), following a community consultation in 2017. VLC, LibreOffice and GIMP line up alongside Kdenlive, Mozilla Thunderbird and Shotwell. 2 Xorg display server Wayland remains the shape of future display servers, we’re reassured, but thanks to the myriad applications and games that failed to run properly with it, Ubuntu 18.04 restores Xorg. 3 Colour emoji are here This is the feature you’ve really been waiting for. In previous versions, emoji were monochromatic; this is set to change in 18.04 with the arrival of Android’s full-colour, open source versions. 4 Minimal installation Not a replacement for the Ubuntu Minimal ISO, but an actual feature in the installation screen, it’s possible to install Ubuntu 18.04 without all of the additional…

‘linux on galaxy’ demonstrated

“Linux shares the same kernel at the heart of Android OS” The idea of turning a smartphone into a PC is nothing new; it’s already been seen in Microsoft’s Windows 10 Mobile with Continuum, Ubuntu Touch’s Convergence, and the inclusion of Debian in Maru OS. But it hasn’t quite caught on. Realising that most people probably don’t want an actual PC in their pockets, Samsung has been busy working on a new approach. Unofficially known as ‘Linux on Galaxy’, Samsung DeX is currently aimed at high-end Samsung Galaxy smartphones (typically with octa-core processors), and a small section of users: programmers. Based on the idea that developers have notepads and other coding tools installed on their phones for downtime work, Samsung has created a new Linux experience. “Developing applications on a mobile device has…

ubuntu is a ‘first class’ guest under hyper-v

Microsoft’s accommodation of Ubuntu is either pleasing or desperate, depending on how you look at it. Regardless, it’s set to continue, following the release of plans to make it a ‘first-class’ guest under the Hyper-V virtualisation platform available in Windows. Under Enhanced Session Mode, Ubuntu 18.04 will be ready to run at any time. In a blog post, Microsoft’s Craig Wilhite, a program manager, explains how his team is “partnering with Canonical on the upcoming Ubuntu 18.04 release to make this experience a reality […] to provide a solution that works out of the box. Hyper-V’s Quick Create VM gallery is the perfect vehicle to deliver such an experience.” The implication is that the “VM experience is tightly integrated with the host […]. With only three mouse clicks, users will be able…
