Picture your disk space with 3-D filesystem browsers
You don't need a Ph.D. in scientific visualization to have some fun with three-dimensional data. Whether you're searching for an unused nook in a cramped disk partition, or trying to find the bloated temp/ folder that's crashing your system, sometimes the flat folder view of a traditional GUI file browser is little help. Luckily, Linux offers a variety of 3-D filesystem that can make your disk usage statistics come alive.
Take File System Visualizer (FSV), for instance. When you launch FSV, the view port brings up a 3-D palette representing the current working directory.
The top surface of the directory is filled with smaller blocks depicting all of the items inside -- files, directories, even symbolic links -- and each block is scaled to show proportionally how much space it takes up out of the whole. That's real handy if you've been using the same hard drive for years, and forget how much space all those term papers you bought for your college Ethics class are eating up.
You can navigate around your entire filesystem with the tree view on the left side, but be careful -- whenever you switch directories, FSV has to calculate the sizes for your new location. If you go all the way to /, it could take a while.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |

re: Picture your disk space
I had a Bioinformatics professor that always said:
"You can hide a thousand lies in a simple graph, but numbers show only the truth" (which isn't 100% accurate, but gets the point across in a poetic way - or at least memorable, since it's been years and years since I had that class).
I never saw (no pun intended) the advantages these 3D systems say they offer. Unless you have just a handful of files, the clutter soon obscures anything but the most basic of patterns or exceptions (i.e the details are lost in the fog).
