Moved from a Linux server to a NAS…

One of my disk in my RAID6 array of my Linux server dropped from the disk array, so it was time to decide the future of my old and trusty server. I have been running a Linux server as my home storage for +15 years. But the family life is limiting my tinker time… So I decided to try an off-the-shelf storage solution (Synolog DiskStation DS918+), to see if this can serve my server needs, without the additional hassle of building and maintaining a Linux server.

Currently I’m running the NAS with 2x8TB WD Red in RAID1, and WD Black NVMe SSD 250GB as (read) cache.

C# – XBox 360 Controller library with a sample application

Created an easy to use XBox 360 Controller library in C# (with a sample application) using the SharpDX.XInput managed .NET wrapper of the DirectX API.

Screenshot of the sample application.

A BUG in SharpDX.XInput ci-ci217, resulting in issues with the  left Thumb Stick, Left Trigger, and Right Trigger! Please stick to SharpDX.XInput v4.1.0-ci184 for now.

Duck Hunt VR (for the HTC Vive)

My first little Unity 3D Virtual Reality project, inspired by my old friend the Nintendo Entertainment System. Please keep in mind the I have never used Unity 3D before, so this is my first sandbox application…

Download link to DuckHuntVR Alpha 04:

This Alpha 04 release incorporated a lot of used feedback from the Vive subreddit:

In particular the feedback gathered during this live coding session:
