Social Augmentations in Multi-User Virtual Reality: A Virtual Museum Experience

Roth D., Kleinbeck C., Feigl T., Mutschler C., Latoschik M. E.In: Proceedings of the International Symposium on Mixed and Augmented Reality (ISMAR) 2017.This work in progress report demonstrates a novel approach for behavioral augmentations in Virtual Reality (VR). Using a large scale tracking system, groups of five users explored a virtual museum. We investigated how augmenting social interactions impacts this experience, by designing behavioral transformations for behavioral phenomena in social interactions. Preliminary data indicate a reduction of perceived isolation, and a more thought-provoking experience with active behavioral augmentations.DOI: 10.1109/ISMAR-Adjunct.2017.28URL: Download


Clone (disk to disk) Ubuntu (14.x) LVM2 to a larger harddisk with Clonezilla and GParted and allocate free space within Ubuntu

How to clone Ubuntu 14.04.5 LTS (GNU/Linux 3.16.0-30-generic i686) to a larger disk?

CUDA (8.x, 9.x) problems with MATLAB (2017b) and Mac OS (10.12.6)

No matter if you mess around with energy savings ("GPU auto switch") or force your GPU to select either intern or discrete GPU mode ("gfxCardStatus" application): this thing will not work! Best way to use parallel computing in MATLAB though, uninstall CUDA and use MATLAB's "parallel cpu toolbox", or use an eGPU.         *This only holds for Apple MacBooks with an internal discrete GPU e.g. NVidia GT650M or GT750M (so models before 2016)


Uninstall Nvidia CUDA (8.x, 9.x) on Mac OS 10.x

According to  running just sudo /usr/bin/ should be enough to uninstall any version of NVidia's CUDA driver, but ... it fails (there's no such file at all)! So, I went through the following steps semi-manually to remove it successfully: sudo /Developer/NVIDIA/CUDA-8.0/bin/ sudo /Developer/NVIDIA/CUDA-9.0/bin/ sudo rm -rf /System/Library/Extensions/CUDA.kext sudo rm -rf /Library/Frameworks/CUDA.framework sudo rm -rf /Library/LaunchAgents/com.nvidia.CUDASoftwareUpdate.plist sudo rm -rf /Library/PreferencePanes/CUDA/Preferences.prefPane sudo rm -rf /System/Library/StartupItems/CUDA sudo rm -rf /Developer/NVIDIA/CUDA* sudo rm -rf /usr/local/cuda Restart your system and "right-click" and remove the CUDA preference icon in the system control app.


CryptoCoin NiceHash – nheqminer 5.0c for Mac OS (10.12)

Compiled the latest miner (cpu and gpu/cuda8 support) from the sources here Provide the binaries for miners interested to mine coins on Apple hardware and software. All you have to do is, 1) install cuda 8 and 2) run the miner e.g.:  ./nheqminer-cpu -d 0 -t 16 -e 1 -l -u workername -p workerpassword Maybe you have to adjust (r)paths of the executables, or export path in the runtime environment: LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib:/usr/local/cuda/lib/stubs" PATH="$PATH:/usr/local/cuda/" PATH="$PATH:/usr/local/cuda/bin" Download miner

QDirStat port: iDirStat monitors your disk space; QDirStat and WinDirStat for Mac OS

MAC OS X Sierra 10.12.X compatible disk space monitor and statistic user interface and editor (25.05.2017) Download Edited QDirStat: base at which based on Qt-based directory statistics: KDirStat without any KDE -- from the author of the original KDirStat. (c) 2015-2017 Stefan Hundhammer Target Platforms: Linux, BSD, Unix-like systems, License: GPL V2, Updated: 2017-05-25 QDirStat is a graphical application to show where your disk space has gone and to help you to clean it up. This is a Qt-only port of the old Qt3/KDE3-based KDirStat, now based on the latest Qt 5. It does not need any KDE libs or infrastructure. It runs on every…
