  • 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

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!

  • Duplicity 0.8.01

    Duplicity 0.8.01 is now in rawhide. The big change here is that it now uses Python 3. I’ve tested it in my own environment, both on it’s own and with deja-dup, and both work.

    Please test and file bugs. I expect there will be more, but with Python 2 reaching EOL soon, it’s important to move everything we can to Python 3.

This does not help the end user, because when people come searching for solutions to genuine concerns like this, they first have to filter through outbursts of pent-up frustration as a result of many years of salesy bullshit.

    From the technological point of view, there's nothing new here. However, the fact you now get non-security nonsense with security means you can't really trust updates from Microsoft anymore. So if anything, this will majestically backfire. People don't like being pushed, and I'm amazed with the repeated attempts to do so, again and again.

  • AMD resolves Destiny 2, Linux crashes via AGESA update

    AMD has confirmed that a bug causing Destiny 2 and selected Linux distributions to fail to run on its latest Zen 2-based Ryzen 3000 series processors will need a microcode update to resolve - but claims it has distributed the necessary code to its motherboard partners already.

    AMD's third-generation Ryzen processors, based on the company's Zen 2 microarchitecture, are undeniably impressive - but users of some software packages have been reporting incompatibility issues. For gamers, the headline was Destiny 2 refusing to run when running on any system with a Ryzen 3000 series processor installed; for Linux users, an incompatibility between the chips and selected versions of the systemd init system and related software suite. In both cases, the issue was the same: a complete inability to use the software without reverting to older hardware.

  • AMD Sends Out Linux Graphics Driver Patches For "Arcturus" As New Vega Derived GPU

    Remember last September when that AMD Arcturus codename dropped in our forums for what at first appeared to be a successor to Navi but later clarified to be used as a Linux driver enablement codename? Well, the Linux kernel driver patches for this "Arcturus" GPU have just been posted.

    This Radeon Arcturus support comes just a few weeks after the Radeon RX 5000 "Navi" Linux driver support was posted. But indeed this "Arcturus" part isn't based on Navi but rather a new swing on Vega based on Vega 20 in part. And we haven't heard of "Arcturus" at any recent AMD events nor from leaks on the more Windows focused sites.

Linux kernel announces a patch to allow 0.0.0.0/8 as a valid address range

Last month, the team behind Linux kernel announced a patch that allows 0.0.0.0/8 as a valid address range. This patch allows for these 16m new IPv4 addresses to appear within a box or on the wire. The aim is to use this 0/8 as a global unicast as this address was never used except the 0.0.0.0.

In a post written by Dave Taht, Director of the Make-Wifi-Fast, and committed by David Stephen Miller, an American software developer working on the Linux kernel mentions that the use of 0.0.0.0/8 has been prohibited since the early internet due to two issues.

    The x86 platform driver updates were sent in and already merged for the ongoing Linux 5.3 kernel. It's the x86 platform driver updates that bring the recently mentioned Intel Speed Select Technology for Linux driver but there is also more.

    Beyond the interesting Intel Speed Select support, the ASUS WMI driver has gone through a refactoring in order to support ASUS' TUF Gaming laptops. In the process, there's even been a regression fix for once popular Eee PC laptop models where their backlight were stuck permanently off.

  • Intel Speed Select Technology Comes To Linux With The 5.3 Kernel

    With the in-development Linux 5.3 kernel is now support for Intel Speed Select Technology (SST) that was introduced as part of Cascade Lake processors. Speed Select Technology allows optimizing the system with per-core performance configurations to prioritize certain workloads while lowering the performance envelope for other cores.

    With the Linux 5.3 kernel there is now an Intel Speed Select Technology driver with these granular power/performance controls. With Cascade Lake and newer, these power and performance profiles can be configured from the OS and done dynamically based upon the real-time needs.

  • Latest Gnu Octave Available to Install via Snap in Ubuntu

    Gnu Octave finally offers official Snap package for Linux desktops, so far in beta, which means you can now easily install the latest Octave via Ubuntu Software and always keep updated.

    Octave snap is a containerized software package comes with run-time libraries bundled and auto-updates itself once a new version package is published.

  • Octave turns to snaps to reduce dependency on Linux distribution maintainers

    Octave is a numerical computing environment largely compatible with MATLAB. As free software, Octave runs on GNU/Linux, macOS, BSD, and Windows. At the 2019 Snapcraft Summit, Mike Miller and Jordi Gutiérrez Hermoso of the Octave team worked on creating an Octave snap in stable and beta versions for the Snap Store.

    As Mike and Jordi explained, “Octave is currently packaged for most of the major distributions, but sometimes it’s older than we would like.” The goal of the Octave snap was to allow users to easily access the current stable release of the software, independently of Linux distribution release cycles. A snap would also let them release Octave on distributions not covered so far.

    Before starting with snaps, Octave depended on distribution maintainers, including those of CentOS, Debian, Fedora, and Ubuntu, for its binary packaging. With snaps, the situation has improved. The Octave team can now push out a release as soon as it ready for users eager to get it now, while other more conservative users wait for more traditional packages from their distribution. Mike and Jordi envisioned this to be the biggest benefit of coming to the Summit and creating an Octave snap.

OSI and Linux Foundation: Takeover by Proprietary Software Giants With Back Doors

Filed under
OSS
  • Thierry Carrez: Open source in 2019, Part 3/3

    As mentioned in part 2, since open source was coined in 1998, software companies have evolved ways to retain control while producing open source software, and in that process stripped users of some of the traditional benefits associated with F/OSS. But those companies were still abiding to the terms of the open source licenses, giving users a clear base set of freedoms and rights.
    Over the past year, a number of those companies have decided that they wanted even more control, in particular control of any revenue associated with the open source software. They proposed new licenses, removing established freedoms and rights in order to be able to assert that level of control. The open source definition defines those minimal freedoms and rights that any open source software should have, so the Open Source Initiative (OSI), as steadfast guardians of that definition, rightfully resisted those attempts.
    Those companies quickly switched to attacking OSI's legitimacy, pitching "Open Source" more as a broad category than a clear set of freedoms and rights. And they created new licenses, with deceptive naming ("community", "commons", "public"...) in an effort to blur the lines and retain some of the open source definition aura for their now-proprietary software.
    The solution is not in redefining open source, or claiming it's no longer relevant. Open source is not a business model, or a constantly evolving way to produce software. It is a base set of user freedoms and rights expressed in the license the software is published under. Like all standards, its value resides in its permanence.

Tizonia – powerful open source cloud music player for the Linux terminal

Filed under
Software

The Linux platform has matured into an excellent way of listening to streaming music services. There are clients available for most of the popular music streaming services. But what if you want a single app that covers the very popular ones without straying away from the Linux terminal. Step forward Tizonia.

Tizonia offers access to some excellent streaming music services — all from the command line. The software supports popular services such as YouTube, Spotify, Google Play Music, SoundCloud, Chromecast, and more.

Tizonia is innovative software. It doesn’t use FFmpeg, libav, gstreamer or libvlc for playback. Instead, the software’s multimedia framework is based on OpenMAX IL 1.2. OpenMAX (Open Media Acceleration) is a non-proprietary and royalty-free cross-platform set of C-language programming interfaces. It provides abstractions for routines that are especially useful for processing of audio, video, and still images.

Tizonia is C/C++ software which integrates online services with Python connectors/proxies. This means it should be fairly easy to integrate new services, assuming a Python-based API is accessible.

What Is AppImage in Linux?

Filed under
GNU
Linux

On a Linux distro, you should always install new software with the aid of your package manager when possible. It keeps things clean, and all files are tracked by the manager and can be easily removed later. This also helps avoid potential trouble when you later upgrade your distribution. But since your distribution might not have the software you need, or some might be too old, you sometimes have to resort to alternatives. Out of all these alternatives, though, only choose to download third party “.deb” or “.rpm” files as a last resort.

What Is AppImage?

On Windows, you can download a ZIP archive, extract the contents to a directory, and run the application within, without having to install it. This is called a portable app because you can copy it to a USB stick and then run it on any computer that uses the Windows operating system.

An AppImage, though technically constructed in a different way, works the same from the user’s perspective. You download one file and run the program on your Linux operating system without having to install anything. Furthermore, you can also copy this on a USB stick, and it will run on Debian, Ubuntu, Arch Linux, openSUSE, Fedora, or any other Linux distribution.

  • D9VK for translating D3D9 to Vulkan for Wine has another new version out, 0.13f - "Hypnofrog"

    Developer Joshua Ashton is certainly keeping busy, with another brand new release of D9VK now available.

    As a reminder: D9VK is based on DXVK. While DXVK focuses on translating D3D11 and D3D10 into Vulkan for use in Wine, D9VK focuses on D3D9. Eventually, they should hopefully merge into one awesome project.

    Version 0.13f - "Hypnofrog" is coming in less than a week after the last release, yet still manages to sound interesting given that's not a lot of time. There's some "New General API Stuff", "New Fixed Function Support", "New Shader Support" and bug fixes for "D3D9" and "DXSO (Shader Fixes)".

    Most of the changelog is highly technical language for those of you who understand graphics APIs. The main takeaway, as always, is that each new release should bring more compatibility with Windows games in Wine that use DirectX 9. Since D9VK uses Vulkan, it should perform better than vanilla Wine.

  • D9VK 0.13f Brings Extra Features For Direct3D 9 Over Vulkan

    It was just earlier this month that D9VK 0.13 was released with new features while now a "0.13f" Hypnofrog release is available in pre-release form.

Software

The LXD team is very excited to announce the release of LXD 3.15!

This release both includes a number of major new features as well as some significant internal rework of various parts of LXD.

One big highlight is the transition to the dqlite 1.0 branch which will bring us more performance and reliability, both for our cluster users and for standalone installations. This rework moves a lot of the low-level database/replication logic to dedicated C libraries and significantly reduces the amount of back and forth going on between C and Go.

On the networking front, this release features a lot of improvements, adding support for IPv4/IPv6 filtering on bridges, MAC and VLAN filtering on SR-IOV devices and much improved DHCP server management.

We’re also debuting a new version of our resources API which will now provide details on network devices and storage disks on top of extending our existing CPU, memory and GPU reporting.

And that’s all before looking into the many other performance improvements, smaller features and bugfixes that went into this release.

Google, Money and Censorship in Free Software communities

Alexander Wirt (formorer) has tried to justify censoring the mailing list in various ways. Wirt is also one of Debian's GSoC administrators and mentors, it appears he has a massive conflict of interest when censoring posts about Google. Wirt has also made public threats to censor other discussions, for example, the DebConf Israel debate. The challenges of holding a successful event in that particular region require a far more mature approach. Why are these donations and conflicts of interest hidden from the free software community who rely on, interact with contribute to Debian in so many ways? Why doesn't Debian provide a level playing field, why does money from Google get this veil of secrecy? [...] Google also operates a mailing list for mentors in Google Summer of Code. It looks a lot like any other free software community mailing list except for one thing: censorship. Look through the "Received" headers of messages on the mailing list and you can find examples of messages that were delayed for some hours waiting for approval. It is not clear how many messages were silently censored, never appearing at all. Recent attempts to discuss the issue on Google's own mailing list produced an unsurprising result: more censorship.

IBM, Red Hat and Fedora Leftovers

  • OpenShift 4: Image Builds

    One of the key differentiators of Red Hat OpenShift as a Kubernetes distribution is the ability to build container images using the platform via first class APIs. This means there is no separate infrastructure or manual build processes required to create images that will be run on the platform. Instead, the same infrastructure can be used to produce the images and run them. For developers, this means one less barrier to getting their code deployed. With OpenShift 4, we have significantly redesigned how this build infrastructure works. Before that sets off alarm bells, I should emphasize that for a consumer of the build APIs and resulting images, the experience is nearly identical. What has changed is what happens under the covers when a build is executed and source code is turned into a runnable image.

  • libinput's new thumb detection code

    The average user has approximately one thumb per hand. That thumb comes in handy for a number of touchpad interactions. For example, moving the cursor with the index finger and clicking a button with the thumb. On so-called Clickpads we don't have separate buttons though. The touchpad itself acts as a button and software decides whether it's a left, right, or middle click by counting fingers and/or finger locations. Hence the need for thumb detection, because you may have two fingers on the touchpad (usually right click) but if those are the index and thumb, then really, it's just a single finger click. libinput has had some thumb detection since the early days when we were still hand-carving bits with stone tools. But it was quite simplistic, as the old documentation illustrates: two zones on the touchpad, a touch started in the lower zone was always a thumb. Where a touch started in the upper thumb area, a timeout and movement thresholds would decide whether it was a thumb. Internally, the thumb states were, Schrödinger-esque, "NO", "YES", and "MAYBE". On top of that, we also had speed-based thumb detection - where a finger was moving fast enough, a new touch would always default to being a thumb. On the grounds that you have no business dropping fingers in the middle of a fast interaction. Such a simplistic approach worked well enough for a bunch of use-cases but failed gloriously in other cases.

While that statistic alone is eye popping, these numbers, according to the report, are only expected to grow in the coming years, fueled by more organizations embracing hybrid cloud infrastructures. As a result, there is immense opportunity for Red Hat partners and potential partners to capitalize on the growth and power of RHEL.

  • The NeuroFedora Blog: NEURON in NeuroFedora needs testing

    We have been working on including the NEURON simulator in NeuroFedora for a while now. The build process that NEURON uses has certain peculiarities that make it a little harder to build. For those that are interested in the technical details, while the main NEURON core is built using the standard ./configure; make ; make install process that cleanly differentiates the "build" and "install" phases, the Python bits are built as a "post-install hook". That is to say, they are built after the other bits in the "install" step instead of the "build" step. This implies that the build is not quite straightforward and must be slightly tweaked to ensure that the Fedora packaging guidelines are met.

Software: Genome Browsers, EtherCalc and Curl

  • Best Free Web Based Genome Browsers

    In the fields of molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus. The study of the genome is called genomics. In bioinformatics, a genome browser is a graphical interface for display of information from a biological database for genomic data. They are important tools for studying genomes given the vast amounts of data available. They typically load very large files, such as whole genome FASTA files and display them in a way that users can make sense of the information there. They can be used to visualize a variety of different data types. Genome browsers enable researchers to visualize and browse entire genomes with annotated data including gene prediction and structure, proteins, expression, regulation, variation, comparative analysis, etc. They use a visual, high-level overview of complex data in a form that can be grasped at a glance and provide the means to explore the data in increasing resolution from megabase scales down to the level of individual elements of the DNA sequence. There’s a wide range of web based genome browsers. We’re going to restrict our selection to the top 4.

  • Get going with EtherCalc, a web-based alternative to Google Sheets

    EtherCalc is an open source spreadsheet that makes it easy to work remotely and collaborate with others.

  • Daniel Stenberg: curl 7.65.2 fixes even more

    Six weeks after our previous bug-fix release, we ship a second release in a row with nothing but bug-fixes. We call it 7.65.2. We decided to go through this full release cycle with a focus on fixing bugs (and not merge any new features) since even after 7.65.1 shipped as a bug-fix only release we still seemed to get reports indicating problems we wanted fixed once and for all. Download curl from curl.haxx.se as always! Also, I personally had a vacation already planned to happen during this period (and I did) so it worked out pretty good to take this cycle as a slightly calmer one. Of the numbers below, we can especially celebrate that we’ve now received code commits by more than 700 persons!
