  • Windows 7 Enters the Last Six Months of Support [Ed: Microsoft propagandist (for ages) Bogdan Popa won't advise people to hop over to GNU/Linux (which he lies about, saying Microsoft "loves Linux")]

    According to third-party data provided by NetMarketShare, Windows 7 continues to be one of the most popular choices for desktop users.

  • Security bootcamp: 8 must-read books for leaders

    The threat of cybercrime constantly looms over business leaders – and it becomes more urgent as cyber attacks become more sophisticated. In 2019, security breaches happen more frequently, and the associated financial hit has increased, according to research from Accenture.

    Notably, the report points out that hackers increasingly target humans – the “weakest link in cyber defenses” – at all levels of organizations, through tactics like ransomware and phishing. (Witness the recent wave of ransomware attacks against U.S. cities, large and small.) That’s why it’s becoming essential for everyone – not just security professionals – to be well-versed in risk and their organization’s security efforts.

  • Security scanning your DevOps pipeline

    Security is one of the most important considerations for running in any environment, and using open source software is a great way to handle security without going over budget in your corporate environment or for your home setup. It is easy to talk about the concepts of security, but it's another thing to understand the tools that will get you there. This tutorial explains how to set up security using Jenkins with Anchore.

    There are many ways to run Kubernetes. Using Minikube, a prepackaged virtual machine (VM) environment designed for local testing, reduces the complexity of running an environment.

  • This Is Why We Have Betas. iOS 13 Beta Shows Saved Passwords

    There’s a reason we have beta versions of software: all the kinks need to be worked out. This is also why using beta versions always come with warnings and disclaimers that you’re using the software at your own risk.

    Users of the iOS 13 beta have discovered that there’s a bug that makes it easy to access the data in “Website & App Passwords” in the Settings app. Certainly, this is something Apple needs to get fixed before the official release, expected for September.

  • Hackers breached Bulgaria’s tax agency and leaked the data of 5M people

    Bulgaria has suffered what has been described as the biggest data leak in its history. The stolen data, which hackers emailed to local media on July 15, originates from the country’s tax reporting service – the National Revenue Agency (NRA).

    The breach contains the personal data of 5 million citizens, local outlet Capital reports. To put that into perspective, Bulgaria has a population of 7 million. Among other things, the trove includes personal identifiable numbers, addresses, and even income data.

  • The 2019 MacBook Air Has 35% Slower SSD Than 2018 Model

    Tests were conducted on MacBook Air variants with different internal storage options and the drop in the write speeds were witnessed in every variant regardless of the internal storage.

  • 11-Year-Old Girl’s iPhone 6 Exploded Burning Holes In Blanket

    With smartphones from various tech companies falling prey to the exploding game, it seems like it’s Apple’s turn, as this time an iPhone caught fire in Bakersfield, California.

    It is suggested that 11-year-old Kayla Ramos was sitting in her sister’s bedroom and was holding the iPhone 6 in her hands. She mostly used it for watching YouTube videos and sometimes gave it to her younger siblings.

  • How many kinds of USB-C™ to USB-C™ cables are there?

    Why did it come to this? This problem was created because the USB-C connectors were designed to replace all of the previous USB connectors at the same time as vastly increasing what the cable could do in power, data, and display dimensions. The new connector may be and virtually impossible to plug in improperly (no USB superposition problem, no grabbing the wrong end of the cable), but sacrificed for that simplicity is the ability to intuitively know whether the system you've connected together has all of the functionality possible. The USB spec also cannot simply mandate that all USB-C cables have the maximum number of wires all the time because that would vastly increase BOM cost for cases where the cable is just used for charging primarily.

    How can we fix this? Unfortunately, it's a tough problem that has to involve user education. [...]

Programming: Thread Synchronization, Python, C++

Development
  • Thread Synchronization in Linux and Windows Systems, Part 1

    In modern operating systems, each process has its own address space and one thread of control. However, in practice we often face situations requiring several concurrent tasks within a single process and with access to the same process components: structures, open file descriptors, etc.

  • Intro to Black – The Uncompromising Python Code Formatter

    There are several Python code checkers available. For example, a lot of developers enjoy using Pylint or Flake8 to check their code for errors. These tools use static code analysis to check your code for bugs or naming issues. Flake8 will also check your code to see if you are adhering to PEP8, Python’s style guide.

  • Report from the February 2019 ISO C++ meeting (Library)

    Back in February, I attended the WG21 C++ standards committee meeting in rainy Kona, Hawaii (yes, it rained most of the week). This report is so late that we’re now preparing for the next meeting, which will take place mid-July in Cologne.

    As usual, I spent the majority of my time in the Library Working Group (for LWG; for details on the various Working Groups and Study Groups see Standard C++: The Committee). The purpose of the LWG is to formalize the specification of the C++ Standard Library, i.e. the second “half” of the C++ standard (although in terms of page count it’s closer to three quarters than half). With a new C++20 standard on the horizon, and lots of new features that people want added to the standard library, the LWG has been very busy trying to process the backlog of new proposals forwarded by the Library Evolution Working Group (LEWG).

    One of the main tasks at the Kona meeting was to review the “Ranges Design Cleanup” proposal. The cleanup involves a number of fixes and improvements to the new Ranges library, addressing issues that came up during the review of the previous (much larger) proposal to add the Ranges library, which is one of the biggest additions to the C++20 library (most of the other significant additions to C++20 affect the core language, without much library impact). In fact, I’d say it’s one of the biggest additions to the C++ standard library since the first standard in 1998. The Ranges library work overhauls the parts of the standard that originated in the Standard Template Library (STL), i.e. iterators, algorithms, and containers, to re-specify them in terms of C++ Concepts. This has been a multi-year effort that has now landed in the C++20 working draft, following multiple proposals and several meetings of wording review by LWG.

  • Save and load Python data with JSON

    JSON stands for JavaScript Object Notation. This format is a popular method of storing data in key-value arrangements so it can be parsed easily later. Don’t let the name fool you, though: You can use JSON in Python—not just JavaScript—as an easy way to store data, and this article demonstrates how to get started.

Raspberry Pi 4 and Raspbian Buster: Hands-On

Filed under
Linux

In my previous two posts I looked at the Raspberry Pi 4 hardware and at the procedure for installing and booting the new Raspbian Buster Operating System on the Pi 4. With those basic steps out of the way, now it's time to look at both the hardware and software in more detail.

The first thing I want to mention is that when I wrote the previous post about Raspbian, I had not noticed that there is an updated version of Raspbian Buster (2019-07-10) available. This version was released sort of quietly (without the usual blog post announcing and explaining it), although there are release notes for it if you are interested. This release is extremely good news, because it fixes some of the biggest problems that I mentioned in my previous post...

Fedora Community Blog: Application service categories and community handoff

Filed under
Red Hat

The Community Platform Engineering (CPE) team recently wrote about our face-to-face meeting where we developed a team mission statement and developed a framework for making our workload more manageable. Having more focus will allow us to progress higher priority work for multiple stakeholders and move the needle on more initiatives in a more efficient manner than how we are working right now.

During the F2F we walked through the process of how to gracefully remove ourselves from applications that are not fitting our mission statement. The next couple of months will be a transition phase as we want to ensure continuity and cause minimum disruption to the community. To assist in that strategy, we analysed our applications and came up with four classifications to which they could belong.

  • A Vulkan Extension Is Being Worked On To Acquire Exclusive Control Of A Wayland Display

    Drew DeVault of Sway/WLROOTS fame has been dabbling with his first Vulkan extension as part of work with other upstream Wayland developers on DRM lease support and better supporting VR headsets under Wayland.

    Being worked on in-step with DRM lease protocol support for Wayland, Drew is also drafting a "VK_EXT_acquire_wl_display" extension for Vulkan. That new extension is akin to VK_EXT_acquire_xlib_display for X11 but for working on Wayland. The existing VK_EXT_acquire_xlib_display extension allows a Vulkan application / game engine to take exclusive control of a display currently associated with an X11 screen. This goes along with the DRM lease support and was spearheaded by Red Hat, Valve, NVIDIA, and Intel as part of Steam VR support on Linux.

  • AMDGPU DC Gets A Number Of Fixes For Navi & Other Clean-Ups

    The past few weeks while AMD open-source developers were busy getting their Navi enablement code public and aligned for the Linux 5.3 merge window, the display core "DC" frequent code drops ceased. Every so often AMD developers volley their DC patches from their internal development trees to the public mailing list for queuing ahead of the next cycle. Now that Navi is out there and getting stabilized, they've issued a new set of DC patches and it's coming in heavy.

    Given that it's been a while during Navi review and upstreaming, the AMDGPU DC patches sent out on Monday are 87 patches that add nearly ten thousand lines of new code.

  • AMDVLK 2019.Q3.2 Released With Navi 10 Support

    Just over one week after the Radeon RX 5700/5700XT "Navi" graphics cards began shipping, the AMDVLK open-source AMD Radeon Vulkan Linux driver support is now available for these first RDNA offerings.

    AMDVLK is the official open-source AMD Vulkan Linux driver and is based on the same sources as the Windows/Linux Radeon Software Vulkan driver. The open-source AMDVLK, however, uses their LLVM-based shader compiler rather than AMD's long-standing proprietary shader compiler. AMDVLK is an alternative to the Mesa RADV Vulkan driver maintained by the "community" (principally, Red Hat, Google, and Valve) that did see launch-day support last week for Navi.

Arduino from the Command Line: Break Free from the GUI with Git and Vim!

Filed under
Linux
Hardware

The word "Arduino" often invokes a wide range of opinions and sometimes emotion. For many, it represents a very low bar to entry into the world of microcontrollers. This world before 2003 often required costly, obscure and closed-source development tools. Arduino has been a great equalizer, blowing the doors off the walled garden. Arduino now represents a huge ecosystem of hardware that speaks a (mostly) common language and eases transition from one hardware platform to another. Today, if you are a company that sells microcontrollers, it's in your best interest to get your dev boards working with Arduino. It offers a low-friction path to getting your products into lots of hands quickly.

It's also important to note that Arduino's simplicity does not inhibit digging deep into the microcontroller. Nothing stops you from directly twiddling registers and using advanced features. It does, however, decrease your portability between boards.

  • Foliate Ebook Reader Picks Up Mobi & Amazon Kindle Support

    The Foliate ebook reader app for Linux has added support for additional ebook formats, including those used by the Amazon Kindle.

    Now, I’m conscious that I’ve mentioned Foliate a lot recently. I generally don’t like to do that — anyone remember the omg! docky! days? — but some developers are so dang prolific, able to knock out notable update after notable update at a regular clip, that I have no choice!

    Foliate’s developer, John Factotum, is one such dev — nice work!

  • The Gecko Hacker's Guide to Taskcluster

    I spent a good chunk of this year fiddling with taskcluster configurations in order to get various bits of continuous integration stood up for WebRender. Taskcluster configuration is very flexible and powerful, but can also be daunting at first. This guide is intended to give you a mental model of how it works, and how to add new jobs and modify existing ones. I'll try and cover things in detail where I believe the detail would be helpful, but in the interest of brevity I'll skip over things that should be mostly obvious by inspection or experimentation if you actually start digging around in the configurations. I also try and walk through examples and provide links to code as much as possible.

Events: Plasma Sprint, PyCon, SciPy and All Systems Go!

  • Plasma sprint, 2019 edition; personal updates

    In June, I had a great time at a series of KDE events held in the offices of Slimbook, makers of fantastic Neon-powered laptops, at the outskirts of Valencia, Spain. Following on from a two-day KDE e.V. board of directors meeting, the main event was the 2019 edition of the Plasma development sprint. The location proved to be quite ideal for everything. Slimbook graciously provided us with two lovely adjacent meeting rooms for Plasma and the co-located KDE Usability & Productivity sprint, allowing the groups to mix and seperate as our topics demanded - a well-conceived spatial analog for the tight relationship and overlap between the two.

    [...]

    In KDE e.V. news, briefly we stole one of the sprint rooms for a convenient gathering of most of our Financial Working Group, reviewing the implementation of the annual budget plan of the organization. We also had a chance to work with the Usability goal crew (have you heard about KDE goals yet?) on a plan for the use of their remaining budget -- it's going to be exciting.

    As a closing note, it was fantastic to see many new faces at this year's sprint. It's hard to believe for how many attendees it was their first KDE sprint ever, as it couldn't have been more comfortable to have them on board. It's great to see our team grow.

  • Real Python at PyCon US 2019

  • Gaurav Agrawal: GSOC Progress by Mid July

    July Marked the beginning of II GSOC coding month. This month our goal is to make the diff bar model as accurate and intuitive as possible.

    One of the biggest thing which I learnt so far is how to contribute on upstream repositories on which our project depends.

    In our case this was with Libgit2, we discovered a bug in Libgit2 while doing our project, and Albfan made this a perfect example to show me how to contribute on upstream, how to raise bugs and how to do discussions for getting it solved.

  • You can't say Go without Google – specifically, our little logo, Chocolate Factory insists

    Back in 2009, Google chose to name its latest programming language Go, a decision that is still giving it a migraine

    It could have called it "Google Go" to avoid confusion with Frank McCabe's Go! programming language. Despite criticism, it didn't do so. After almost a year of online grumbling, Google software engineer Russ Cox, in 2010, closed GitHub Issue #9, dismissing the complaints as "unfortunate."

    And the headaches over the thing's name still won't go away (no pun intended.) Last week, Google rebuffed a request to remove its logo from the Go website, golang.org, a change supported by some developers who feel Google takes Go developers for granted.

  • Achievement Unlocked: RetroArch is Coming to Steam

    Fans of retro (and not so retro) gaming will be pleased to hear that RetroArch is coming to Steam.

    Not familiar with RetroArch? It’s a user-friendly GUI that makes use of the libretro API. That API allows developers to create, among other things, modular ‘libretro’ cores that act as game emulators for systems like the SNES, Mega Drive and Game Boy.

    The famed front-end for the popular Libretro API will be available to install on Steam for Windows from July 30. Linux and macOS versions will follow.

    The libretro cores that power RetroArch can be used with other compatible frontends (like GNOME Games app) but RetroArch is arguably the best one.

IBM, Red Hat and Fedora

Filed under
Red Hat
  • IBM Takes A Hands Off Approach With Red Hat

    IBM has been around long enough in the IT racket that it doesn’t have any trouble maintaining distinct portfolios of products that have overlapping and often incompatible functions. The System/3, which debuted in 1969, is only five years older than the System/360, which laid the foundation and set the pace for corporate computing when it launched in 1964. Both styles of machines continue to exist today as the IBM i on Power Systems platform and the System z.

    With the $34 billion acquisition of Red Hat, which closed last week, neither of those two legacy products are under threat and IBM does not seem to be inclined whatsoever in ceasing development of the legacy operating system and middleware stacks embodied in the IBM i and System z lines.

    As Arvind Krishna, senior vice president in charge of IBM’s cloud and cognitive software products, put it bluntly in a call after the deal closed, IBM’s customers expect for Big Blue to maintain its own operating systems, middleware, storage, databases, and security software in the IBM i, AIX, and System z lines, and that is precisely what Big Blue is going to do. Krisha estimated that there is only about 5 percent overlap in products between Big Blue and Red Hat – something we talked about at length when the deal was announced last October – and added that in many enterprise accounts that use both Red Hat and IBM platforms, companies invest in both sets of software for different purposes – perhaps using JBoss in one case and WebSphere in another, for instance.

  • Tech cos go for Edtech tie-ups to get that ready workforce

    Companies like Wipro, Accenture, IBM and others are tying up with edtech partners like upGrad, Simplilearn and Udacity to have a ready-trained workforce they can deploy on projects. Additional benefits include minimal training cost incurred post recruitment and a lesser churn as learners develop more ownership in their roles.

    The edtech firms provide campus recruits the required platform, content, assignments and project work in their last semester of college to ensure they are prepared with programming skills and emerging digital skills before they join.

  • Red Hat Enterprise Linux 8 improves performance for modern workloads

    Red Hat Enterprise Linux (RHEL) 8 can provide significant performance improvements over RHEL 7 across a range of modern workloads. To put this in context, we used RHEL 7.6 to execute multiple benchmarks with Intel's 2nd generation of Intel Xeon Scalable processors, and our hardware partners set 35 new world record performance results using the same OS version. This post will highlight RHEL 8 performance gains over RHEL 7.

    How did we get here? The performance engineering team at Red Hat collaborates with software partners and hardware OEMs to measure and optimize performance across workloads that range from high-end databases, NoSQL databases packaged in RHEL, Java applications, and third party databases and applications from Oracle, Microsoft SQL Server, SAS, and SAP HANA ERP applications.

    We run multiple benchmarks and measure the performance of CPU, memory, disk I/O and networking. Testing includes the filesystems we ship with Red Hat Enterprise Linux, such as XFS, Ext4, GFS2, Gluster and Ceph.

  • Federation V2 is now KubeFed

    Some time ago we talked about how Federation V2 on Red Hat OpenShift 3.11 enables users to spread their applications and services across multiple locales or clusters. As a fast moving project, lots of changes happened since our last blog post. Among those changes, Federation V2 has been renamed to KubeFed and we have released OpenShift 4.

    In today’s blog post we are going to look at KubeFed from an OpenShift 4 perspective, as well as show you a stateful demo application deployed across multiple clusters connected with KubeFed.

    There are still some unknowns around KubeFed; specifically in storage and networking. We are evaluating different solutions because we want to we deliver a top-notch product to manage your clusters across multiple regions/clouds in a clear and user-friendly way. Stay tuned for more information to come!
