  • And the Race is On! 2018-2019 openSUSE Board Elections Enter Campaign Phase

    Marina is a very active Italian openSUSE Advocate, involved in the Project since 2009, deeply involved in LibreOffice.  She relocated to Munich last June, where she is working for CIB mainly on its LibreOffice team as Senior Migrations & Deployments Engineer.  You may read more about Marina on her Wiki User page.

    Marina joins an already impressive line-up of Quality Candidates who announced they were stepping up during the past week, adding to what will be very tough decisions for the Voters in the upcoming Elections.  Official openSUSE Members in Good Standing are qualified to vote in the Elections, and they will have to make difficult choices for who should take the three open Board Seats, choosing between Marina, incumbent Christian Boltz aka cboltz, Dr. Axel Braun aka DocB, incumbent Sarah Julia Kriesch aka AdaLovelace, Sébastien Poher aka sogal, Vinzenz Vietzke aka vinzv, and Nathan Wolf aka futureboy and CubicleNate on IRC.

    Sarah and Sébastien’s run for the Board was announced in last Wednesday’s openSUSE News, while the Candidacies of Christian, Dr. Braun, Vinzenz, and  Nathan were announced in the next day’s news article.

  • Entry-level Bay Trail SBC ready for workhorse duty

    Acrosser’s 3.5-inch “AMB-BT19S1” SBC runs on an Intel Bay Trail SoC and offers up to 8GB RAM, dual display support, plus SATA, mSATA, mini-PCIe, serial, USB 3.0, and GbE ports.

    With newer Atom processor families such as Cherry Trail, Braswell, Apollo Lake, and now Gemini Lake, the popular, five-year old Bay Trail product line appears to be close to “legacy” status. Yet, aside from graphics capabilities and support for the latest memories and peripherals, there’s not that much separating Bay Trail from Gemini Lake in terms of CPU performance and power consumption. Depending on the price, an “entry level” Bay Trail SBC like Acrosser’s 3.5-inch AMB-BT19S1 board could be the smart move for some applications.

Particularly with the FP16 cuDNN support, this chess engine can be super fast on NVIDIA's latest Turing GPUs with tensor cores. 

    With LCZero's build process being sane for its different back-ends and the program turning out to be benchmark-friendly and meeting my requirements, it's now available via the Phoronix Test Suite with a simple phoronix-test-suite benchmark lczero (granted, the back-end support may obviously vary depending upon your hardware/driver support) and more details over on OpenBenchmarking.org.

  • Smith and Winston Enters Early Access for Linux and Windows

    The rise of Geometry Wars 15 years ago on the original Xbox led to a slew of imitators across all platforms. However, the biggest thing it did was revive the long-dead twin-stick shooter genre. Small attempts had been made to revive it in the form of a new Robotron game in the late '90s, but nothing stuff until Bizarre Creations' fun little side game brought the shooting sub-genre back into the limelight again. Later full-fledged entries saw it gain even more popularity, and since then, it's had a bit of a downward turn once again. Enter Smith and Winston - beyond its gun brand-inspired name, you have a game that blends retro with modern in a unique way.

  • Etch a Sketch lives on in browser-based Chrome Labs project

    Everyone who remembers the Etch A Sketch slabs of yesteryear remembers how difficult it was to translate your vision onto its "magic screen," and how proud you felt upon success. Now, Google's Chrome Labs has translated that experience (quite literally) for the digital age with the fun Web A Skeb project. It's a browser-contained version of an Etch A Sketch that you can use to draw and doodle—if you can get the hang of its dials.

    [...]

    Google's Chrome Labs lets developers make weird, fun, and interesting projects to show the power that a simple Web browser has. Those involved have produced things like the open source image compression tool Squoosh, the Web actor library Clooney, and Project VisBug, a Chrome extension that lets users edit webpages using design tool interactions and hotkeys.

    Web A Skeb is available not only in Chrome but in other desktop and mobile browsers as well. It's actually a bit easier to draw on mobile, since you can use both of your thumbs to turn the dials at the same time. Those interested can check out the source code on GitHub.

  • AWS, MongoDB database collision stirs open source tensions

    AWS' introduction of the DocumentDB managed database service sparks competition with the backers of the popular MongoDB database, as well as debate over the nature of open source licensing.

    DocumentDB is a fully managed document database service that is compatible with MongoDB workloads. Rather than build on MongoDB's core code base, it implements an API that supports workloads from MongoDB 3.6 and earlier. This effectively emulates the responses that a MongoDB client expects from a MongoDB server, and customers can use their existing MongoDB drivers and tools, AWS said.

    MongoDB is the fifth-most popular database today, according to ranking site DB-Engines.com. Its parent company provides commercial support for the service, which went public in October 2017 and is now valued at more than $4 billion.

  • Texas Linux Fest 2019 in Dallas

    A few years ago I started to suggest to TXLF staff that coming to Dallas was a good idea. I wanted there to be more tech conferences in Dallas, and I love the community organized nature of TXLF and similarly SCALE. Plus, it was Texas Linux Fest, it can't always be in Austin! This year I was able to convince them to take the risk and try a year in Dallas. It is a huge risk, as it is likely that many sponsors and regular attendees might not be interested in traveling up I-35 to attend. Being in Dallas also opens up huge opportunity to reach new audiences and new sponsors. Now to prove that.

  • Linux Fu: The Kitchen Sync

    One of the great things about Linux and similar operating systems is they are configurable. If you don’t like something, there’s a great chance you can change it easily with a few entries in a file somewhere. For example, take bash — a very popular shell by any measure. If you want a different style of command line editing, there’s an option. You want the tab key to match files regardless of case? Another option. Usually, these are set in one of your so-called profile files like .bashrc in your home directory.

    As long as you are sitting in front of your single computer working, this is great. You customize your .bashrc and other files to your heart’s content and then you work in an environment that acts the way you want it to. The problem is when you have a lot of computers. Maybe you have a web server, a desktop, a firewall machine, and a few dozen Raspberry Pi computers. How do you keep all the configurations the same? Then once they are the same, how do you keep them up to date?

  • AWS gives open source the middle finger

    AWS launched DocumentDB today, a new database offering that is compatible with the MongoDB API. The company describes DocumentDB as a “fast, scalable, and highly available document database that is designed to be compatible with your existing MongoDB  applications and tools.” In effect, it’s a hosted drop-in replacement for MongoDB that doesn’t use any MongoDB code.

    AWS argues that while MongoDB is great at what it does, its customers have found it hard to build fast and highly available applications on the open-source platform that can scale to multiple terabytes and hundreds of thousands of reads and writes per second. So what the company did was build its own document database, but made it compatible with the Apache 2.0 open source MongoDB 3.6 API.

  • Open-source microscope targets brain imaging and disease diagnosis

    A team of researchers at Tel Aviv University in Israel has developed a new multiphoton microscopy tool, known as Pysight, for rapid 2D and 3D imaging of the brain and other tissues.

    Among other things, the team hopes that the tool could soon boost scientists' efforts to attain a deeper understand of brain dynamics, assisting in the discovery of groundbreaking treatments for a range of health problems including stroke, epilepsy and dementia.

    Pablo Blinder, who heads up the team at the Neurobiology, Biochemistry and Biophysics School and Sagol School for Neuroscience at Tel Aviv University, explains that PySight combines commercially available, off-the-shelf hardware with open-source software tailored for photon-depleted imaging conditions, such as those characteristic of rapid multiphoton microscopy.

    “[PySight’s] commercial hardware converts the noisy output of each photodetector into uniform photon detection events, and registers their absolute arrival time with a temporal precision of 100 picoseconds,” he says.

    “Its software package then reads the resulting list of photon arrival times, determines the respective origin within the brain of each detected photon, and generates volumetric movies over time.”

    In a recent paper published in the journal Optica, Blinder and his co-authors demonstrate the benefits of using PySight for tracking neuronal activity in awake mice and fruit flies. While initially developed with neuroimaging purposes in mind, Blinder reveals that the tool could just as easily be used for a range of other imaging applications - including detection of malignant cells in human patients during surgical procedures.

  • Gergely Nagy: One hat less

    At the time, I was... a different person. I was full of myself at times, I was angry, perhaps a tad too elitist at times too. I'm not proud of old me, but it's part of me. I grew, and became a better person, there's no shame in being able to grow - quite the contrary. And Debian helped immensely. I've had role models in the project, who I look up to even to this day, who helped shape me one way or the other.

    There are two people I need to mention specifically: Martin Michlmayr and Rhonda D'Vine.

    Martin was my Application Manager when I applied, I considered him a mentor, a friend. The example he set were instrumental in shaping me too. Rhonda helped me get to my first ever conference: I got on a train to Vienna, and she took me to LinuxTag in her car from there, and then back again. That first LinuxTag, the path that led there, the conference itself, was formative, and both Martin and Rhonda had a big part in it being so. Thank you again - so many years later, I still smile when I think back. Those years we were in touch, meant a lot to me.

These tweaks have been usually set in the runtimes and applications using these runtimes automatically inherited all the needed permissions during the build. This has some weak spots, because changing permissions in the runtime requires all applications to be rebuild to pick up the changes, or applications not using the runtimes at all had to allow all the access themself and really not everyone knows what everything needs to be enabled.

Nate Swanner, editor of Dice Insights, noted that Kubernetes – and to a lesser extent Terraform – led the demand of skill requests toward “containerization of apps and services, as well as the cloud.” Terraform is an infrastructure as code software by HashiCorp.

  • The Quest to Topple Science-Stymying Academic Paywalls

    SCIENCE IS BUILT, enhanced, and developed through the open and structured sharing of knowledge. Yet some publishers charge so much for subscriptions to their academic journals that even the libraries of the world’s wealthiest universities such as Harvard are no longer able to afford the prices. Those publishers’ profit margins rival those of the most profitable companies in the world, even though research is largely underwritten by governments, and the publishers don’t pay authors and researchers or the peer reviewers who evaluate those works. How is such an absurd structure able to sustain itself—and how might we change it?

    When the World Wide Web emerged in the ’90s, people began predicting a new, more robust era of scholarship based on access to knowledge for all. The internet, which started as a research network, now had an easy-to-use interface and a protocol to connect all of published knowledge, making each citation just a click away … in theory.

    Instead, academic publishers started to consolidate. They solidified their grip on the rights to prestigious journals, allowing them to charge for access and exclude the majority of the world from reading research publications—all while extracting billions in dollars of subscription fees from university libraries and corporations. This meant that some publishers, such as Elsevier, the science, technology, and medicine-focused branch of the RELX Group publishing conglomerate, are able today to extract huge margins—36.7 percent in 2017 in Elsevier’s case, more profitable than Apple, Google/Alphabet, or Microsoft that same year.

  • The Solderdoodle Open Source Iron Rides Again

    Now, [Isaac] is back with an updated version he calls the Solderdoodle Plus. It’s still based on the heating element from the Weller BP645, but now boasts twice the power, an improved 3D printed case, an intuitive touch-based user interface, and even some LED blinkenlights for good measure. As with the original Solderdoodle the hardware and software for the device are open source and you’re invited to build your own, though kits are also available through an already fully-funded Kickstarter campaign.

    [Isaac] says that the temperature control functions on traditional corded soldering irons waste energy due to the large thermal mass they have to bring up to temperature. But with less thermal mass and a system of variable duty cycle pulsed power, he says the Solderdoodle Plus can do the same work as an old-school 60 watt iron while only consuming 10 watts. This allows the iron to maintain a constant 500°C for over an hour on the dual internal Panasonic NCR18500A lithium-ion batteries, and means you can charge it up with nothing more exotic than a micro USB cable.

  • How Trulia began paying down its technical debt

    As every software company knows, over time as code ages and workarounds build on work-arounds, the code base becomes bloated. It becomes ever more difficult to get around the technical debt that you’ve built up over time. It’s really impossible to avoid this phenomenon, but at some point, companies realize that the debt is so great that it’s limiting their ability to build new functionality. That’s precisely what Trulia faced in 2017 when it began a process of paying down that debt and modernizing its architecture.

    Trulia is a real estate site founded way back in 2005, an eternity ago in terms of technology. The company went public in 2012 and was acquired by Zillow in 2014 for $3.5 billion, but has continued to operate as an independent brand under the Zillow umbrella. It understood that a lot had changed technologically in the 12 years since its inception when engineering began thinking about this. The team knew it had a humongous, monolithic code base that was inhibiting the ability to update the site.

  • NetBSD Exploring LLVM's LLD Linker For Lower Memory Footprint
    The NetBSD project has been making good progress in utilizing the LLVM compiler stack not only for the Clang C/C++ compiler but also for the different sanitizers, the libc++ standard library for C++, and other improvements most of which are working their way into the upstream code-bases. One area of NetBSD's LLVM support being explored most recently is using the LLD linker. NetBSD is exploring the use of the LLVM LLD linker over GNU's ld linker due to the lower memory footprint. LLD generally goes through far less RAM than the current GNU ld linker.
  • Finding Compiler Bugs With C-Reduce
    Support for a long awaited GNU C extension, asm goto, is in the midst of landing in Clang and LLVM. We want to make sure that we release a high quality implementation, so it’s important to test the new patches on real code and not just small test cases. When we hit compiler bugs in large source files, it can be tricky to find exactly what part of potentially large translation units are problematic. In this post, we’ll take a look at using C-Reduce, a multithreaded code bisection utility for C/C++, to help narrow done a reproducer for a real compiler bug (potentially; in a patch that was posted, and will be fixed before it can ship in production) from a real code base (the Linux kernel). It’s mostly a post to myself in the future, so that I can remind myself how to run C-reduce on the Linux kernel again, since this is now the third real compiler bug it’s helped me track down.

  • Intel Vulkan Linux Driver Adds Conditional Rendering, Draw Indirect Count
    First up, the Intel Vulkan driver now supports VK_EXT_conditional_rendering after a lengthy review/revision process. VK_EXT_conditional_rendering was added to Vulkan 1.1.80 last July and allows for rendering commands to be made selective based upon a value in the buffer memory, in order to allow discard rendering commands based upon a result in GPU memory without having to wait on the application/engine. The conditional rendering can be used with Vulkan draws, compute dispatches, and clearing of attachments. VK_EXT_conditional_rendering is supported by Haswell "Gen 7.5" graphics and newer with the upcoming Mesa 19.0.

Get started with Roland, a random selection tool for the command line

There seems to be a mad rush at the beginning of every year to find ways to be more productive. New Year's resolutions, the itch to start the year off right, and of course, an "out with the old, in with the new" attitude all contribute to this. And the usual round of recommendations is heavily biased towards closed source and proprietary software. It doesn't have to be that way. Here's the seventh of my picks for 19 new (or new-to-you) open source tools to help you be more productive in 2019. Read more

Nginx vs Apache: Which Serves You Best in 2019?

For two decades Apache held sway over the web server market which is shrinking by the day. Not only has Nginx caught up with the oldest kid on the block, but it is currently the toast of many high traffic websites. Apache users might disagree here. That is why one should not jump to conclusions about which web server is better. The truth is that both form the core of complete web stacks (LAMP and LEMP), and the final choice boils down to individual needs. For instance, people running Drupal websites often call on Apache, whereas WordPress users seem to favor Nginx as much if not more. Accordingly, our goal is to help you understand your own requirements better rather than providing a one-size recommendation. Having said that, the following comparison between the two gives an accurate picture. Read more
