On the Removal of toSet(), toList() and Others or “How Do I Convert a QList to QSet in Qt 6?”
by Giuseppe D’Angelo
Between Qt 5.14 and Qt 5.15, my colleague, Marc Mutz, and I submitted a series of patches to Qt that added “range constructors” to the Qt containers. This brought Qt containers one step closer to…C++98 feature parity! 🙂
State of Native Big File Handling in Git
by Miłosz Kosobucki
After many struggles with using git LFS on repositories that need to store big files, I decided to spend some time on checking the status of the built-in partial clone functionality that could possibly let you achieve the same (as of git 2.30).
TL;DR: The building blocks are there, but server-side support is spotty and critical tooling is missing. It’s not very usable yet, but it’s getting there.
Kuesa Object Picking
by Andrew Hayzen
In a 3D scene, you may want to allow the user to select entities within the scene and then the scene to react depending on what has been selected. For example, if a certain object within a scene is selected, a popup could be shown displaying extra information or a visual hint could point towards the selected object.
Kuesa 3D Studio accelerates time-to-market by taking the pain out of rapid customization and iteration of 3D designs. Designers and developers love it.
