  • 8 Top Free and Open source Desktop GIS mapping software

    Well, in the term “Open source GIS Software”, opensource refers to a program that is available to use free of cost; along with source code that one can modify either to improve the existing project or creating a new one under GPL. Whereas GIS means Geographical Information Systems, in terms of software, it is a program that one can run on their PC or server to analyze, store, manipulate, process and visualize data in a spatial context; and describes relevant geographical distribution data in the space of all or part of the earth’s surface (including the atmosphere), supported by computer hardware and software systems. [...] QGIS desktop geographic information system (GIS) application was earlier known as Quantum GIS. It supports cross-platform Windows, Linux and macOS. We can integrate it with other open-source GIS packages such as PostGIS, GRASS GIS, and MapServer. It supports extensions that are written in Python or C++ to extend its functionality. [...] SAGA stands for System for Automated Geoscientific Analyses that designed to implement spatial algorithms. It provides easy to understand and usable graphical user interface with a set of tools and with many visualisation options. It runs under Windows and Linux operating systems. It includes standard modules such as File access, Filter for grids, Gridding, Geostatistics, Grid calculator, Grid discretisation, Grid tools, 3D mapping, Projections, Terrain analysis and more…

  • Marketing Is Becoming Technology-Driven, and the Future Is Open Source

    The idea of buying proprietary software is arguably questionable. Still, the choice to acquire it could be driven by the lack of a talent pool to customize or integrate non-proprietary software, or peer pressure to go for bigger, bulkier proprietary applications.

Kernel: KVM Protected Memory Extension and MediaTek

  • Intel Engineer Proposes Software-Based KVM Protected Memory Extension

    While modern AMD EPYC CPUs support Secure Encrypted Virtualization (SEV) and Intel more recently has been working on MKTME for similarly offering hardware-backed total memory encryption, an Intel open-source engineer has now proposed a software-based solution for protected memory support for KVM virtualization. The proposed KVM protected memory extension is a software-based solution for protecting guest memory from unauthorized host access, at least in partial form. This prevents the host kernel from accidentally leaking guest data, host user-space access to guest data, and similar solutions. But unlike Intel MKTME and AMD SEV, this does not provide full protection against the host kernel being compromised or hardware-based attacks.

  • Many MediaTek Wireless Driver Improvements On Deck For Linux 5.8

    There is a lot of wireless (and wired) networking activity each kernel cycle but for the upcoming Linux 5.8 merge window it looks like there will be particularly a lot for MediaTek drivers. The MediaTek MT76 driver work now queued in wireless-drivers-next ahead of Linux 5.8 has around 14 thousand lines of new code. Among the MediaTek wireless highlights are: - New device support for MediaTek MT76x0 and MT76x2 hardware. - MT7615 and MT7663 fixes.
