Foss4G Japan 2021 シェープファイルの真の後継規格 FlatGeobufの普及啓蒙活動Kanahiro Iguchi
?
This document summarizes a presentation about FlatGeobuf, a new vector format standard that aims to replace Shapefiles. It introduces FlatGeobuf as a simpler format than GeoPackage that addresses Shapefile limitations like file size restrictions and character encoding issues. FlatGeobuf uses FlatBuffers and stores geometry and attributes in a single file, offering high performance for reading, writing, and streaming partial data compared to other formats. The document advocates for adopting FlatGeobuf as the new standard vector format.

IoT Devices Compliant with JC-STAR Using Linux as a Container OSTomohiro Saneyoshi
?
Security requirements for IoT devices are becoming more defined, as seen with the EU Cyber Resilience Act and Japan’s JC-STAR.
It's common for IoT devices to run Linux as their operating system. However, adopting general-purpose Linux distributions like Ubuntu or Debian, or Yocto-based Linux, presents certain difficulties. This article outlines those difficulties.
It also, it highlights the security benefits of using a Linux-based container OS and explains how to adopt it with JC-STAR, using the "Armadillo Base OS" as an example.
