Linux Malware Detect (LMD) is a malware scanner for Linux released under the GNU GPLv2 license, that is designed around the threats faced in shared hosted environments. It uses threat data from network edge intrusion detection systems to extract malware that is actively being used in attacks and generates signatures for detection. In addition, threat data is also derived from user submissions with the LMD checkout feature and from malware community resources. The signatures that LMD uses are MD5 file hashes and HEX pattern matches, they are also easily exported to any number of detection tools such as ClamAV.

Unused RAM is wasted RAM, so why not put some of that VRAM in your graphics card to work?
vramfs is a utility that uses the FUSE library to create a file system in VRAM. The idea is pretty much the same as a ramdisk, except that it uses the video RAM of a discrete graphics card to store files. It is not intented for serious use, but it does actually work fairly well, especially since consumer GPUs with 4GB or more VRAM are now available.
On the developer's system, the continuous read performance is ~2.4 GB/s and write performance 2.0 GB/s, which is about 1/3 of what is achievable with a ramdisk. That is already decent enough for a device not designed for large data transfers to the host, but future development should aim to get closer to the PCI-e bandwidth limits. See the benchmarks section for more info.
