Seastar is an advanced, open-source C++ framework for high-performance server applications on modern hardware. Applications using Seastar can run on Linux or OSv.
Seastar is the first framework to bring together a set of extreme architectural innovations, including:
Shared-nothing design: Seastar uses a shared-nothing model that shards all requests onto individual cores.
High-performance networking: Seastar offers a choice of network stack, including conventional Linux networking for ease of development, DPDK for fast user-space networking on Linux, and native networking on OSv.
Futures and promises: an advanced new model for concurrent applications that offers C++ programmers both high performance and the ability to create comprehensible, testable high-quality code.
Message passing: a design for sharing information between CPU cores without time-consuming locking.
CANtact is an open source Controller Area Network (CAN) to USB interface for your computer.
Lychee is a free photo-management tool, which runs on your server or web-space. Installing is a matter of seconds. Upload, manage and share photos like from a native application. Lychee comes with everything you need and all your photos are stored securely.

BRL-CAD (Ballistic Research Laboratory CAD) is a powerful cross-platform open source solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, image and signal-processing tools, a system performance analysis benchmark suite, libraries for robust geometric representation, with more than 20 years of active development.
Die Diskussion ist fast so alt wie die IT: Wie viel Dokumentation benötigt ein System? Während es für den Kunden oft nicht genug sein kann, möchte der typische Entwickler am liebsten ausschließlich Code erzeugen. Eine leicht falsch interpretierbare Aussage aus dem Agilen Manifest zum Thema Dokumentation hat die Diskussion noch weiter aufgeheizt. Guter Rat scheint teuer. Aber so schwierig ist es letztlich gar nicht und ein wenig Systematik bei den Dokumentationsarten sowie gerade die agilen Prinzipien helfen, Inhalt und Umfang einer guten Systemdokumentation zu optimieren. In diesem Artikel werden zwei einfache Werkzeuge vorgestellt, die helfen, Dokumentation nicht mehr auf “Verdacht” zu erstellen, sondern zielgerichtet nach Sinn und Wert zu optimieren.
In this tutorial I explain how to compile and install Kicad from the bzr source repositories and how to setup footprint library tables to use local copies of the footprint libraries. Windows users, please see the comment from Thomas Knapp for some advice on how to build on Windows.

Matrix is an open standard for decentralised communication, providing simple HTTP APIs and open source reference implementations for securely distributing and persisting JSON over an open federation of servers.
FreeCAD is a parametric 3D modeler. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters. FreeCAD is open source (LGPL license) and completely modular, allowing for very advanced extension and customization.
FreeCAD is multiplatfom, and reads and writes many open file formats such as STEP, IGES, STL and others.
