welcome to issue 194 of linux user & developer

Welcome to the UK and North America’s No.1 Linux and open source magazine. I was chatting to Michael Meeks at the Collabora offices recently (see p12) and something struck me about his response to the GitHub acquisition. He was less interested in Microsoft as the buyer and more focused on the new CEO, Nat Friedman. Friedman has made serious contributions to the open source movement and he’s someone – along with Miguel de Icaza, a founder of GNOME – who’s attributed with encouraging Microsoft to open-source projects such as .NET. So maybe we need to give GitHub a chance? However, we know some of you are considering your Git hosting options, so flip to p34. Just to emphasise we’re not being mean, we’ve got a tutorial on Azure Powershell as well…

private equity buys suse for $2.5 billion

British technology company Micro Focus International has agreed the sale of its business-focused SUSE Linux operating system to private equity firm EQT Partners, for $2.53 billion (around £1.9 billion). Now in its 26th year, SUSE has been under the wing of Micro Focus International since 2014, when the company merged with Attachmate, which had previously purchased SUSE as part of Novell in 2011. SUSE had been part of Novell’s plan to get its business back on track with an acquisition in 2003; Novell’s technologies will remain with Micro Focus. Originally developed in Germany, SUSE has long seen itself as a competitor to Red Hat Linux. Just as Red Hat Linux has the free Fedora, so SUSE has openSUSE. As with Red Hat Linux, SUSE generates revenue from technical support (PC and server),…

new cpu flaw hits older linux systems

Hot on the heels of the Meltdown and Spectre CPU bugs comes Lazy FPU, a newly discovered bug that enables floating point data to be misused. But while this is a vulnerability that can be exploited in a similar way to its infamous predecessors, it is one that can be patched far more easily, and without the performance hits that patching Meltdown and Spectre incurred. Indeed, mitigation of this bug actually improves system performance. Better still, Lazy FPU doesn’t affect modern versions of Linux (kernel 4.9 onwards), Windows or the most recent OpenBSD and DragonflyBSD. However, the Linux team is reported to be working on mitigation measures for pre-4.9 kernels. The bug – discovered by chance during ongoing investigation into Spectre-Meltdown – is found only in Intel Core (Nehalem and later) and…

raspbian update brings new pi features

“ The Recommended Software tool helps to reduce menu clutter” Fresh from the Raspberry Pi Foundation is a new version of the Debian-based Raspbian desktop, optimised for the Raspberry Pi 3 B+ and boasting a number of new features. Primary among these is the ‘first-boot setup’ wizard, a long-overdue inclusion that guides the user through setup options, as with most other Linux distributions. Adding the ability to set location, check for updates, add a password (ending, at last, the security issue of the default username and password), and choose Wi-Fi networks, this feature is automatically disabled for subsequent boots. It can, however, be accessed at any time using the piwiz command in the terminal. Following the launch of the Raspberry Pi in 2012, the short-lived Pi Store provided an easy way to install approved…

canonical shares desktop metrics

Canonical has revealed that 67 per cent of users opted-in to the collection of desktop metrics when installing Ubuntu 18.04 LTS. Controversial upon its announcement, the Ubuntu Report tool was integrated into setup to record hardware and localisation options. Intended to help Canonical understand what systems are running Ubuntu – and how it can improve the OS – the decision to include the tool has reportedly turned long-term Ubuntu users away from the distro. That’s despite assertions from Canonical that the reporting is not an actual privacy breach (no user-identifiable information is shared), and the fact that all data is available to review by the user before it’s even sent. While some of the information revealed is a little dry, Canonical has been able to get an idea of the current state…
