  • Hazelcast joins Eclipse Foundation to collaborate on open source enterprise Java

    Hazelcast, the open source In-Memory Data Grid (IMDG) with tens of thousands of installed clusters and over 39 million server starts per month, announced it had joined the Eclipse Foundation, bringing extensive Java-driven community experience to a host of open source projects.

    Working collaboratively with other members of the Eclipse community, Hazelcast’s primary focus will be on JCache, the Eclipse MicroProfile and EE4J.

    In particular, Hazelcast will be collaborating with members to popularise JCache, a Java Specification Request (JSR-107) which specifies API and semantics for temporary, in-memory caching of Java objects, including object creation, shared access, spooling, invalidation, and consistency across JVM’s. These operations help scale out applications and manage their high-speed access to frequently used data. In the Java Community Process (JCP), Hazelcast’s CEO, Greg Luck, has been the co spec lead and then maintenance lead on “JCache – Java Temporary Caching API” since 2007.

  • GitLab update: Moving to the next step

    I have good news, after few meetings and discussions with GitLab we reached an agreement on a way to bring the features we need and to fix our most important blockers in a reasonable time and in a way that are synced with us. Their team will fix our blockers in the next 1-2 months, most of them will be fix in the release of 22th of December and the rest if everything goes well in the release of 22th of January. The one left that out of those 2 months is a richer UI experience for duplicates, which is going to be an ongoing effort.

    Apologies for the blockage for those that regularly asked to migrate their project, I wanted to make sure we are doing things in the right steps. I also wanted to make sure that I get feedback and comments about the initiative all around in my effort to make a representation of the community for taking these decisions. Now it’s the point where I’m confident, the feedback and comments both inside and outside of our core community has been largely that we should start our path to fully migrate to GitLab.

  • Khronos Releases SYCL 1.2.1 With TensorFlow Acceleration, C++17 Alignment

    SYCL as a reminder is Khronos' higher-level OpenCL programming model based on C++. It's been a while since the last update, but a new point release is now available.

    SYCL 1.2.1 is based on OpenCL 1.2 and improves support for machine learning tasks, supports TensorFlow acceleration, and aligns with the latest C++17 standard. SYCL 1.2 had previously been based on C++11/C++14. The C++17 standard was just firmed up this month.

  • Python data classes

    The reminder that the feature freeze for Python 3.7 is coming up fairly soon (January 29) was met with a flurry of activity on the python-dev mailing list. Numerous Python enhancement proposals (PEPs) were updated or newly proposed; other features or changes have been discussed as well. One of the updated PEPs is proposing a new type of class, a "data class", to be added to the standard library. Data classes would serve much the same purpose as structures or records in other languages and would use the relatively new type annotations feature to support static type checking of the use of the classes.

    PEP 557 ("Data Classes") came out of a discussion on the python-ideas mailing list back in May, but its roots go back much further than that. The attrs module, which is aimed at reducing the boilerplate code needed for Python classes, is a major influence on the design of data classes, though it goes much further than the PEP. attrs is not part of the standard library, but is available from the Python Package Index (PyPI); it has been around for a few years and is quite popular with many Python developers. The idea behind both attrs and data classes is to automatically generate many of the "dunder" methods (e.g. __init__(), __repr__()) needed, especially for a class that is largely meant to hold various typed data items.

New: NuTyX 9.93 and Linux Mint 18.3

  • NuTyX 9.93 available with cards 2.3.105
    The NuTyX team is please to annonce the 9.93 release of NuTyX. NuTyX 9.92 comes with kernel LTS 4.14.6, glibc 2.26, gcc 7.2.0, binutils 2.29.1, python 3.6.0, xorg-server 1.19.5, qt 5.10.0, KDE plasma 5.11.3, KDE Framework 5.41.0, KDE Applications 17.12.0, mate 1.18.2, xfce4 4.12.4, firefox 57.0.2 Quantum, etc...
  • Linux Mint 18.3 'Sylvia' Xfce and KDE editions are available for download
    Linux Mint is killing the KDE version of its operaring system -- a move some people applaud. That's what makes the new 18.3 version -- named "Sylvia" -- so frustrating. It's bizarre to release a new version of an operating system that essentially has no future. But oh well, here we are. After a short beta period, the KDE distro is now available for download -- if you still care. I recommend that KDE loyalists just switch to Kubuntu or Netrunner, but I digress. Despite being the final version of Linux Mint KDE, it is still a great alternative to the consistently disappointing Windows 10. After all, it has been discovered that Microsoft is bundling a bug-ridden password-manager with its operating system without user consent! How can you trust such an OS?! Sigh.
  • Linux Mint 18.3 "Sylvia" KDE and Xfce Editions Officially Released, Download Now
    The Linux Mint team released the final Linux Mint 18.3 "Sylvia" Xfce and Linux Mint 18.3 "Sylvia" KDE editions to download, as well as an upgrade for existing Linux Mint 18.2 "Sonya" users. Previously in beta, the Linux Mint 18.3 "Sylvia" KDE and Xfce editions are now officially released and ready for production use. Just like the Cinnamon and MATE flavors, they are based on Canonical's long-term supported Ubuntu 16.04 LTS (Xenial Xerus) operating system and use the Linux 4.10 kernel by default for new installations.

GNU: Glibc, GIMP, GCC

  • Glibc 2.27 Lands Yet More Performance Optimizations
    Earlier this month I wrote how Intel engineers have been busy with continuing to tune glibc's performance with FMA and AVX optimizations. That work has continued but also other architectures continue tuning their GNU C Library performance ahead of the expected v2.27 update. There has been a ton of optimization work this cycle, particularly on the Intel/x86_64 front. For those with newer Intel 64-bit processors, this next glibc release is shaping up to be a speedy update.
  • GIMP PIcks Up Support For The New Flatpak/FreeDesktop.org Screenshot API
    Hot off the release of the new GIMP 2.9.8 and ahead of the expected GIMP 2.10 release candidates that are expected to begin, a new addition to GIMP is a plug-in supporting the new FreeDesktop.org/Flatpak screenshot API. The org.freedesktop.portal.Screenshot specification aims to be a screenshot API that will work not only cross-desktop (e.g. KDE, GNOME, etc) but also work for sandboxed applications (i.e. Flatpak) and also work regardless of whether you are using Wayland or X11.
  • GCC Prepares For Fortran 2018 Support
    The Fortran committee decided last month to rename the upcoming Fortran 2015 programming language update to Fortran 2018. GCC support is being prepped. With this updated programming language technical specification not expected to be published until mid-2018, the committee behind this long-standing programming language decided to rename Fortran 2015 to Fortran 2018. Fortran 2018 should further improve interoperability with C code, improve its parallel programming capabilities, support hexadecimal inputs/outputs, and other improvements over Fortran 2008.

Security: Hackers, Back Doors, Microsoft Scam and Bots

  • Why Hackers Are in Such High Demand, and How They're Affecting Business Culture
    News headlines often focus on the hackers who launch cyber attacks and leak confidential data such as National Security Agency exploits, sensitive political emails, and unreleased HBO programming, but hackers can also affect organizations in positive ways. White hat hackers (as opposed to black hats) increasingly are finding employment in companies as security researchers. From conducting penetration tests and identifying vulnerabilities in software to providing companies with guidance about emerging threats, white hat hackers bring considerable value to organizations and play an instrumental role in helping them defend against today's advanced threats. White hats are highly coveted not only for their knowledge but also for their unique mindsets and ability to change corporate culture.
  • We need to talk about mathematical backdoors in encryption algorithms
    Security researchers regularly set out to find implementation problems in cryptographic algorithms, but not enough effort is going towards the search for mathematical backdoors, two cryptography professors have argued. Governments and intelligence agencies strive to control and bypass or circumvent cryptographic protection of data and communications. Backdooring encryption algorithms is considered as the best way to enforce cryptographic control. In defence of cryptography, researchers have set out to validate technology that underpins the secure exchange of information and e-commerce. Eric Filiol,  head of research at ESIEA, the operational cryptology and virology lab, argued that only implementation backdoors (at the protocol/implementation/management level) are generally considered. Not enough effort is being put into looking for mathematical backdoors or by-design backdoors, he maintains.
  • How a Dorm Room Minecraft Scam Brought Down the Internet
     

    Originally, prosecutors say, the defendants hadn’t intended to bring down the internet—they had been trying to gain an advantage in the computer game Minecraft.
