  • New Software::LicenseMoreUtils Perl module

    Debian project has rather strict requirements regarding package license. One of these requirements is to provide a copyright file mentioning the license of the files included in a Debian package.

    Debian also recommends to provide this copyright information in a machine readable format that contain the whole text of the license(s) or a summary pointing to a pre-defined location on the file system (see this example).

    cme and Config::Model::Dpkg::Copyright helps in this task using Software::License module.

  • 01:C++ Boost libraries can increase productivity

    Writing code for every function in a software can be time consuming and expensive, so many C++ developers prefer to use libraries which contain modules for different applications to increase productivity. While there are already some libraries integrated with the standard C++ programming language, one of the most popular sources of C++ portable libraries is Boost, https://www.boost.org . These boost

  • LLVM 6.0.1 Released

    Tom Stellard at Red Hat has continued with his duties of serving as the LLVM point release manager and today formally issued the LLVM 6.0.1 update.

  • Does your project suffer from technical drift?

    Certainly, if the developer had known this would happen, he or she would not have chosen this implementation (I hope). For you Angularities, we are converting all our apps to use the reactive forms approach. More code, fewer HTML directives—a much better choice for testing and understanding the flow in the application.

Qt/KDE: QtCon Brasil 2018, Qt 5.12 and Qt Creator 4.8.0 Beta 2

  • Talking about Qt and Computer Vision at QtCon Brasil 2018
    I had the opportunity to participate in QtCon Brasil 2018 as a speaker during the last weekend. It happened in São Paulo, which is a city that I haven’t visited for a long time. My talk was about the integration of Qt applications and Computer Vision, specially focused on the mobile environment with QtQuick and QML. During my presentation, I was focused on introducing some concepts to the people who just have heard or never had contact with Computer Vision. I talked a little bit about OpenCV, including an brief explanation about its modules and how they work, and I presented a little example of object recognition application made with QML (the code is available in the repository).
  • Qt Quick Performance Improvements with Qt 5.12 LTS
    Qt 5.9 LTS already shows a great improvement of the overall performance compared to the previous long-term supported Qt 5.6 LTS release. These are summarized in a blog post about Performance Improvements with Qt 5.9 LTS and Qt Quick Performance Improvements on 64-bit ARM. With Qt 5.12 LTS we have continued to tune these further and taken a deeper look into the areas of QML engine memory consumption and JavaScript performance.

  • Qt 5.12 Lowering The QML Memory Consumption, Better JavaScript Performance
    As part of The Qt Company's ongoing improvements to their tool-kit and with Qt 5.12 being an LTS release, this cycle they focused a lot on improving the performance. Qt 5.12 LTS will be releasing in the next few weeks and as part of their performance push they have been working to lowering the memory consumption of the QML engine. The QML data structures have been optimized to reduce their size and better handling around cached objects.
  • Qt Creator 4.8 Beta2 released
    We are happy to announce the release of Qt Creator 4.8.0 Beta2! This release comes with the many fixes that we have done since our first Beta release. Additionally we upgraded the LLVM for the Clang code model to version 7.0, and our binary packages to the Qt 5.12 prerelease.
