Interviews

I think it started when I installed the same Linux distribution with the same set of applications, configuration and layout as mine, to my wife's and then to my colleague's computers. Then somebody asked me why should I not try to share my point of view with more people.

Ubuntu and the suite of GNU tools in any robust Unix system. A good text editor (currently Gedit)—I keep all of my working files at .txts. A robust, highly configurable browser (Firefox/Firefox for Android). A fast RSS reader (presently Google Reader, likely to be Newsblur next). A tetherable mobile connection—I use EasyTether for Android to circumvent tether-blocking as deployed by some of the carriers I use around the world, especially Rogers in Canada. AirDroid for moving files on/off Android devices in my life.

Here’s why Mark Shuttleworth is growing beard

Filed under
Interviews
Ubuntu

“There is a slightly serious angle to beard. One of my colleagues was stopped and held by transport police in UK. He was questioned for hours. There was no justification to it and so while he was leaving, he asked them the reason and they said it was the beard. This is disgusting. A society should be civilised enough to not judge people on the basis of how they look.”

SUSE

The code, set to be released in March, doesn't patch kernel code in-place but rather uses an ftrace-like approach to replace whole functions in the Linux kernel with fixed variants, said Pavlik. SUSE then plans to submit it to the Linux kernel community for upstream integration.

Linux
Interviews

Recently, a High School in Millersville Pa struck a cord with me personally. Like many east coast advocates of Linux, I often have to watch California, Europe, and other countries from the sidelines, engaging fun and interesting Open Source events and projects. Imagine my excitement when I learned of one such champion of Open Source, but not from Europe, from a place not more than a few hours from me. Deploying over 1700 laptops, armed to the teeth with Ubuntu and Open Software to students, I knew there was more to the story than the small stories floating around. Even if for my own personal education, I wanted to know more.

Breaking down geek stereotypes in open source

Filed under
Interviews

I nominate open source particularly because even by tech industry standards, this is the hardcore stuff. When I tell other IT people I work for a Linux company even they sometimes get the haunted look of somebody about to be bombarded with a bunch of stuff they don't know or care about. I really like it though. I like the passion people have. I like that innovation and progress are the big markers of success, and that good ideas are going to naturally work their way to the top. This sort of natural selection shouldn't be limited by who can produce some geek cred. I know it's worn like a badge of pride, but it shouldn't devalue other social structures, especially feminine social structures, in the process.

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
    The Linux Foundation has launched the LF Deep Learning Foundation, an umbrella organisation which will support and sustain open source innovation in artificial intelligence, machine learning, and deep learning. The organisation will strive to make these critical new technologies available to developers and data scientists everywhere, said a statement published by LF. Founding members of LF Deep Learning include Amdocs, AT&T, B.Yond, Baidu, Huawei, Nokia, Tech Mahindra, Tencent, Univa, and ZTE, among others. LF Deep Learning, members are working to create a neutral space where makers and sustainers of tools and infrastructure can interact and harmonise their efforts and accelerate the broad adoption of deep learning technologies.
  • 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.

Security: Updates, GrayKey, Google and Cilium

  • Security updates for Wednesday
  • 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.
  • It's not you, it's Big G: Sneaky spammers slip strangers spoofed spam, swamp Gmail sent files
    Google has confirmed spammers can not only send out spoofed emails that appear to have been sent by Gmail users, but said messages also appear in those users' sent mail folders. The Chocolate Factory on Monday told The Register that someone has indeed created and sent spam with forged email headers. These not only override the send address, so that it appears a legit Gmail user sent the message, but it also mysteriously shows up in that person's sent box as if they had typed it and emitted themselves. In turn, the messages would also appear in their inboxes as sent mail.
  • Cilium 1.0 Advances Container Networking With Improved Security
    For last two decades, the IPtables technology has been the cornerstone of Linux networking implementations, including new container models. On April 24, the open-source Cilium 1.0 release was launched, providing a new alternative to IPtables by using BPF (Berkeley Packet Filter), which improves both networking and security. The Cilium project's GitHub code repository defines the effort as Linux Native, HTTP Aware Network Security for Containers. Cilium development has been driven to date by stealth startup Covalent, which is led by CEO Dan Wendlandt, who well-known in the networking community for his work at VMware on software-defined networking, and CTO Thomas Graf, who is a core Linux kernel networking developer.

Applications: KStars, Kurly, Pamac, QEMU

  • KStars 2.9.5 is out!
    Autofocus module users would be happy to learn that the HFR value is now responsive to changing seeing conditions. Previously, the first successful autofocus operation would set the HFR Threshold value of which subsequent measurements are compared against during the in-sequence-focusing step.
  • Kurly – An Alternative to Most Widely Used Curl Program
    Kurly is a free open source, simple but effective, cross-platform alternative to the popular curl command-line tool. It is written in Go programming language and works in the same way as curl but only aims to offer common usage options and procedures, with emphasis on the HTTP(S) operations. In this tutorial we will learn how to install and use kurly program – an alternative to most widely used curl command in Linux.
  • Pamac – Easily Install and Manage Software on Arch Linux
    Arch Linux is one of the most popular Linux distribution available despite its apparent technicality. Its default package manager pacman is powerful but as time always tells, it is a lot easier to get certain things done using a mouse because GUI apps barely require any typing nor do they require you to remember any commands; and this is where Pamac comes in. Pamac is a Gtk3 frontend for libalpm and it is the GUI tool that Arch Linux users turn to the most when they aren’t in the mood to manage their software packages via the terminal; and who can blame them? It was specifically created to be used with Pacman.
