  • Interview with Noemie Scherer

    Hi! I’m a European Krita user.

    [...]

    That was more than ten years ago. I was something like ten, maybe twelve at most. A friend of mine had a photographer father, so I went to their house and could try his drawing tablet, and it was really cool; some time later my parents got me one (one of those small A6 ones), and my brother downloaded Gimp, probably for a birthday (he was -still is- really into open source).

  • Toyota Prepping 'PASTA' for its GitHub Debut

    Carmaker's open source car-hacking tool platform soon will be available to the research community.
    The lead developer behind Toyota's new cybersecurity testing tool said the carmaker plans to make its so-called PASTA (Portable Automotive Security Testbed with Adaptability) available via GitHub as early as next month or April.

    Tsuyoshi Toyama, senior researcher at Toyota InfoTechnology Center, told Dark Reading that he and his team are currently working on getting the PASTA specifications ready for availability online, and plan to offer as open-source the platform's specs, CAN (controller area network) ID maps, ECU (engine control unit) program codes, and ECU circuit diagrams for vehicle testing. He says Toyota also hopes to offer PASTA's driving simulator programs as open source, as well.

Yesterday, FAIR announced new features and research results related to ELF OpenGo, including an updated model, a Windows executable version of the bot, and a unique archive analyzing 87k professional Go games.

    ELF OpenGo, an open-source reimplementation of the AlphaZero algorithm, is the first open-source Go AI that has convincingly demonstrated superhuman performance, achieving a (20:0) record against global top professionals.

  • Novel software offers possible reduction in arrhythmic heart disease

    Potentially lethal heart conditions may become easier to spot and may lead to improvements in prevention and treatment thanks to innovative new software that measures electrical activity in the organ.

    The heart's pumping ability is controlled by electrical activity that triggers the heart muscle cells to contract and relax. In certain heart diseases such as arrhythmia, the organ's electrical activity is affected.

    Cardiac researchers can already record and analyse the heart's electrical behaviour using optical and electrode mapping, but widespread use of these technologies is limited by a lack of appropriate software.

    Computer and cardiovascular experts at the University of Birmingham have worked with counterparts in the UK, Netherlands and Australia to develop ElectroMap - a new open-source software for processing, analysis and mapping complex cardiac data.

    Led by researchers from the School of Computer Science and the Institute of Cardiovascular Sciences, at the University of Birmingham, the international team has published its findings in Scientific Reports.

  • Open-science model for drug discovery expands to neurodegenerative diseases

    Medicines 4 Neurodegenerative Diseases (M4ND Pharma) will pursue promising new genetic drug targets for these intractable nervous system disorders, thanks to $1.5 million from the Krembil Foundation. It will be the world's second drug discovery company committed to open science after Medicines 4 Kids (M4K Pharma), which launched in 2017 to develop a novel drug for an uncommon but fatal childhood brain cancer.

    Open science is a way for researchers to share their data and knowledge quickly and publicly, unencumbered by patents and the peer review publishing process, with the aim of speeding up scientific discovery. The movement gathered force in the life sciences in the 1990s with the Human Genome Project, and spread to protein structures and then early-stage drug discovery through the Structural Genomics Consortium (SGC).

    The non-profit SGC has generated considerable private and public investment and several spin-out companies, but there remains a gap in late-stage drug development.

    "When we started M4K, many people thought an open approach to late-stage drug development might only be applicable to rare or neglected diseases, if at all," says Aled Edwards, a professor of molecular genetics at the University of Toronto and CEO of the SGC. "But we're getting unexpected funding and scientific contributions from industry, academic and clinical sources, and slowly but surely we're advancing a medicine through the pipeline. It's time to move the goal posts again on what's possible with open science."

How to use Spark SQL: A hands-on tutorial

In the first part of this series, we looked at advances in leveraging the power of relational databases "at scale" using Apache Spark SQL and DataFrames. We will now do a simple tutorial based on a real-world dataset to look at how to use Spark SQL. We will be using Spark DataFrames, but the focus will be more on using SQL. In a separate article, I will cover a detailed discussion around Spark DataFrames and common operations. I love using cloud services for my machine learning, deep learning, and even big data analytics needs, instead of painfully setting up my own Spark cluster. I will be using the Databricks Platform for my Spark needs. Databricks is a company founded by the creators of Apache Spark that aims to help clients with cloud-based big data processing using Spark.

4 questions Uber's open source program office answers with data

It's been said that "Software is eating the world," and every company will eventually become a "software company." Since open source is becoming the mainstream path for developing software, the way companies manage their relationships with the open source projects they depend on will be crucial for their success. An open source program office (OSPO) is a company's asset to manage such relationships, and more and more companies are setting them up. Even the Linux Foundation has a project called the TODO Group "to collaborate on practices, tools, and other ways to run successful and effective open source projects and programs". Read more

Kernel: LWN on Linux 5.1 and More, 'Lake'-named Hardware

  • 5.1 Merge window part 1
    As of this writing, 6,135 non-merge changesets have been pulled into the mainline repository for the 5.1 release. That is approximately halfway through the expected merge-window volume, which is a good time for a summary. A number of important new features have been merged for this release; read on for the details.
  • Controlling device peer-to-peer access from user space
    The recent addition of support for direct (peer-to-peer) operations between PCIe devices in the kernel has opened the door for different use cases. The initial work concentrated on in-kernel support and the NVMe subsystem; it also added support for memory regions that can be used for such transfers. Jérôme Glisse recently proposed two extensions that would allow the mapping of those regions into user space and mapping device files between two devices. The resulting discussion surprisingly led to consideration of the future of core kernel structures dealing with memory management. Some PCIe devices can perform direct data transfers to other devices without involving the CPU; support for these peer-to-peer transactions was added to the kernel for the 4.20 release. The rationale behind the functionality is that, if the data is passed between two devices without modification, there is no need to involve the CPU, which can perform other tasks instead. The peer-to-peer feature was developed to allow Remote Direct Memory Access (RDMA) network interface cards to pass data directly to NVMe drives in the NVMe fabrics subsystem. Using peer-to-peer transfers lowers the memory bandwidth needed (it avoids one copy operation in the standard path from device to system memory, then to another device) and CPU usage (the devices set up the DMAs on their own). While not considered directly in the initial work, graphics processing units (GPUs) and RDMA interfaces have been able to use that functionality in out-of-tree modules for years. The merged work concentrated on support at the PCIe layer. It included setting up special memory regions and the devices that will export and use those regions. It also allows finding out if the PCIe topology allows the peer-to-peer transfers.
  • Intel Posts Linux Perf Support For Icelake CPUs
    With the core functionality for Intel Icelake CPUs appearing to be in place, Intel's open-source developers have been working on the other areas of hardware enablement for these next-generation processors. The latest Icelake Linux patches we are seeing made public by Intel is in regards to the "perf" subsystem support. Perf, of course, is about exposing the hardware performance counters and associated instrumentation that can be exercised by user-space when profiling performance of the hardware and other events.
  • What is after Gemini Lake?
    Based on a 10 nm manufacturing process, the Elkhart Lake SoC uses Tremont microarchitectures (Atom) [2] and features Gen 11 graphics similar to the Ice Lake processors [3]. Intel’s Gen 11 solution offers 64 execution units, and it has managed over 1 TFLOP in GPU performance [4]. This can be compared with the Nvidia GeForce GT 1030 which offered a peak throughput of 0.94 TFLOPs [5]. Code has already been added in the Linux mainline kernel [6] suggesting a possible Computex announcement and mid to late 2019 availability [7].

GNOME Desktop: Parental Controls and GNOME Bugzilla

  • Parental controls hackfest
    Various of us have been meeting in the Red Hat offices in London this week (thanks Red Hat!) to discuss parental controls and digital wellbeing. The first two days were devoted to this; today and tomorrow will be dedicated to discussing metered data (which is unrelated to parental controls, but the hackfests are colocated because many of the same people are involved in both).
  • GNOME Bugzilla closed for new bug entry
    As part of GNOME’s ongoing migration from Bugzilla to Gitlab, from today on there are no products left in GNOME Bugzilla which allow the creation of new tickets. The ID of the last GNOME Bugzilla ticket is 797430 (note that there are gaps between 173191–200000 and 274555–299999 as the 2xxxxx ID range was used for tickets imported from Ximian Bugzilla). Since the year 2000, the Bugzilla software had served as GNOME’s issue tracking system. As forges emerged which offer tight and convenient integration of issue tracking, code review of proposed patches, automated continuous integration testing, code repository browsing and hosting and further functionality, Bugzilla’s shortcomings became painful obstacles for modern software development practices. Nearly all products which used GNOME Bugzilla have moved to GNOME Gitlab to manage issues. A few projects (Bluefish, Doxygen, GnuCash, GStreamer, java-gnome, LDTP, NetworkManager, Tomboy) have moved to other places (such as freedesktop.org Gitlab, self-hosted Bugzilla instances, or Github) to track their issues.
