Smart Cache is shared cache dynamically allocated to each processor core, based on workload. This efficient, dual-core-optimized implementation increases the probability that each core can access data from the fast cache, significantly reducing latency to frequently used data and improving performance.

Sharing folder using ssh



FUSE - Filesystem in Userspace

FUSE is a Linux kernel module also available for FreeBSD, OpenSolaris and Mac OS X that allows non-privileged users to create their own file systems without the need to write any kernel code. This is achieved by running the file system code in user space, while the FUSE module only provides a "bridge" to the actual kernel interfaces. FUSE was officially merged into the mainstream Linux kernel tree in kernel version 2.6.14.

You need to use SSHFS to access to a remote filesystem through SSH

Step # 1: Download and Install FUSE

Browse fuse home page and download latest source code tar ball.

Untar source code:

# tar -zxvf fuse-2.6.5.tar.gz

Flying butterfly animation


Start Maya. Go to Side view. Select EP Curve tool.
Draw a profile curve for the main body of butterfly.
Right-click on the Curve and select Vertex mode.
Refine the shape by moving vertices using move tool.
Make sure “Surfeces” menu-set is selected (‘F4’ is shortcut for Surface menu-set). While the curve is still selected, go to Surfaces > Revolve.
