Lubuntu Next Is Adopting the Calamares Installer, Continues to Be in Development

Filed under
Ubuntu

Lubuntu, the most lightweight official Ubuntu flavor, had a hard time these past few months, during the development cycle of the upcoming Bionic Beaver operating system series, with all sorts of problems, but its small development team managed to get past them and continued to work on both Lubuntu and Lubuntu Next.

While Lubuntu Next offers us the more modern LXQt desktop environment, built on the latest Qt 5 technologies, the upcoming Lubuntu 18.04 LTS release is still using the LXDE desktop environment by default. The switch from LXDE to LXQt for Lubuntu is in the testing phase since Lubuntu 15.10 (Wily Werewolf), but progress is being made on this front.

Review: Gatter Linux 0.8

Filed under
Reviews
Ubuntu

Gatter Linux is an Ubuntu-based distribution which features the Openbox window manager as the default user interface. The project claims to be developing a desktop operating system which is user friendly: "For people who want switch from Windows to [the] Linux world and for people who want [a] lightweight operation system and also fully functional." I could find very little other information on the distribution on its website.

The latest release of Gatter Linux is version 0.8 and it is based on Ubuntu 16.04 LTS. The distribution is available in one edition for 64-bit x86 computers. The ISO the project provides is approximately 830MB in size. Booting from this disc brings up a menu asking if we would like to boot into a live desktop environment, boot a live desktop displayed in safe graphics mode, or launch the project's system installer. Taking the live desktop option brings us to a graphical login screen where we can sign into the default account if we have the right password. I did not find any reference to a password on the project's website, but quickly got signed in by guessing the password "gatter".

The live disc features the Openbox window manager. Openbox has been set up with a fairly sparse layout. There is a panel placed at the top of the screen which shows four unlabeled buttons and a system tray. I soon found the four blank buttons are actually a virtual desktop switcher that lets us switch between workspaces. The theme is dark and minimal.

When we sign in a welcome window appears. This welcome screen features launchers which can open configuration tools. One button launches an application which will switch our keyboard's layout, another button opens a third-party driver manager, a third tool helps us set our time zone. One button marked Gatter Settings opens up a panel with options for changing the appearance of the Openbox environment. Another button is labelled Gatter Software. This button opens a terminal window and displays a menu of possible package-related actions such as updating the system, cleaning the package cache or performing a "dist upgrade".

Intel's Microcode Update for Spectre Makes a Comeback in Ubuntu's Repositories

Filed under
Security
Ubuntu

After it's been pulled from Ubuntu's repositories in late January at Intel's request due to serious hardware issues reported by numerous users, Inte's microcode update to mitigate the Spectre security vulnerability makes a comeback.

On January 22, 2018, Canonical replaced the Intel microcode firmware versioned 20180108 with the older 20170707 release at Intel's request, thus no longer protecting users' computers against the Spectre security vulnerability that could allow a local attacker to expose sensitive information from kernel memory.

"Jann Horn discovered that microprocessors utilizing speculative execution and branch prediction may allow unauthorized memory reads via side-channel attacks. This flaw is known as Spectre. A local attacker could use this to expose sensitive information, including kernel memory (CVE-2017-5715)," reads the security advisory.

How to install and use Gitkraken on Ubuntu with snap

Filed under
Ubuntu
HowTos

If you're a developer, you know Git. Most likely, you use Git on a regular basis. And you probably know Linux as well. In fact, you probably develop with Linux (as Linux is one of the most popular development platforms in the world). If you're a Git user on Linux, you might be using the command line to interact with the service.

However if you could have an outstanding GUI tool for that purpose, you'd probably use it to make your work a bit more efficient. One such tool is the cross platform Gitkraken. With Gitkraken you can easily interact with your Git account, without having to use the command line.

Search ‘Ubuntu based distros’ on Google and laugh at the recommendations as Google shows Arch, Debian etc in the search result.

Ubuntu is based on Debian. Debian is not based on other distribution. Arch Linux is a distribution independent of Debian or any other Linux distribution.

This is what every Linux user already knows.

Openwashing: Microsoft, Apple and Symphony Software Foundation

Linux Foundation: Real-Time Linux (RT Linux), LF Deep Learning Foundation, OpenTracing and More

  • Developers: Prepare Your Drivers for Real-Time Linux
    Although Real-Time Linux (RT Linux) has been a staple at Embedded Linux Conferences for years -- here’s a story on the RT presentations in 2007 -- many developers have viewed the technology to be peripheral to their own embedded projects. Yet as RT, enabled via the PREEMPT_RT patch, prepares to be fully integrated into the mainline kernel, a wider circle of developers should pay attention. In particular, Linux device driver authors will need to ensure that their drivers play nice with RT-enabled kernels. At the recent Embedded Linux Conference in Portland, National Instruments software engineer Julia Cartwright, an acting maintainer on a stable release of the RT patch, gave a well-attended presentation called “What Every Driver Developer Should Know about RT.” Cartwright started with an overview of RT, which helps provide guarantees for user task execution for embedded applications that require a high level of determinism. She then described the classes of driver-related problems that can have a detrimental impact to RT, as well as potential resolutions. One of the challenges of any real-time operating system is that most target applications have two types of tasks: those with real-time requirements and latency sensitivity, and those for non-time critical tasks such as disk monitoring, throughput, or I/O. “The two classes of tasks need to run together and maybe communicate with one another with mixed criticality,” explained Cartwright. “You must resolve two different degrees of time sensitivity.” One solution is to split the tasks by using two different hardware platforms. “You could have an Arm Cortex-R, FPGA, or PLD based board for super time-critical stuff, and then a Cortex-A series board with Linux,” said Cartwright. “This offers the best isolation, but it raises the per unit costs, and it’s hard to communicate between the domains.”
  • Clarifying the Linux Real Time Issue
    I recently posted an article about the increasing development and availability of Linux-powered automation devices. This is a clear industry trend that’s unavoidable for anyone following the automation technology industry. Shortly after posting the article, I heard from a reader who wrote: “I read your article and I am surprised that you would promote the idea that anyone would use Linux for anything critical. It isn’t even a real-time control system. It can be used for non-critical applications, but the article implies that industry is adopting it for everything.” This reader brings up a valid point. Linux is not a real-time OS in and of itself. As Vibhoosh Gupta of GE Automation & Controls noted in the original article, GE uses “Type 1 hypervisor technology to run a real-time OS, such as VxWorks, running traditional control loops alongside our PAC Edge technology operating on Linux.” [...] The Linux Foundation launched the RTL (Real Time Linux) Collaborative Project in October 2015. According to the Foundation, the project was “founded by industry experts to advance technologies for the robotics, telecom, manufacturing and medical industries. The aim of the RTL collaborative project is mainlining the PREEMPT_RT patch.” While there are plenty of mission critical applications running Linux OS with real-time extensions—as highlighted by GE, Opto and Wago—the Linux Foundation notes on its site that there remains “much work to be done.”
  • Linux Launches Deep Learning Foundation For Open Source Growth In AI

  • OpenTracing: Distributed Tracing’s Emerging Industry Standard
    What was traditionally known as just Monitoring has clearly been going through a renaissance over the last few years. The industry as a whole is finally moving away from having Monitoring and Logging silos – something we’ve been doing and “preaching” for years – and the term Observability emerged as the new moniker for everything that encompasses any form of infrastructure and application monitoring. Microservices have been around for a over a decade under one name or another. Now often deployed in separate containers it became obvious we need a way to trace transactions through various microservice layers, from the client all the way down to queues, storage, calls to external services, etc. This created a new interest in Transaction Tracing that, although not new, has now re-emerged as the third pillar of observability.

  • Hackers Leaked The Code Of iPhone Cracking Device “GrayKey”, Attempted Extortion
    The mysterious piece of hardware GrayKey might give a sense of happiness to cops because they can get inside most of the iPhone models currently active, including the iPhone X. The $30,000 device is known to crack a 4-digit iPhone passcode in a matter of a few hours, and a six-digit passcode in 3 days, or possibly 11 hours in ideal scenarios. That’s why security experts suggest that iOS users should keep an alphanumeric passcode instead of an all-number passcode.
  • Someone Is Trying to Extort iPhone Crackers GrayShift With Leaked Code
    Law enforcement agencies across the country are buying or have expressed interest in buying GrayKey, a device that can unlock up-to-date iPhones. But Grayshift, the company that makes the device, has attracted some other attention as well. Last week, an unknown party quietly leaked portions of GrayKey code onto the internet, and demanded over $15,000 from Grayshift—ironically, the price of an entry-level GrayKey—in order to stop publishing the material. The code itself does not appear to be particularly sensitive, but Grayshift confirmed to Motherboard the brief data leak that led to the extortion attempt.
