Interesting links
If you are interested in structural biology or protein structures analysis then these links could be useful for you:

-"The structures of life" brochure will introduce you into the world of proteins in friendly manner.

-"Abbreviations and Symbols for the Description of the Conformation of Polypeptide Chains".

Bioinformatics' tools
Below you will find some tools useful for prediction and comparison of protein structures:

-MinRMS is a program for finding minimal root-mean-squared-distance (RMSD) alignments between two proteins as a function of the number of matching residue pairs.

-The DSSP program was designed by Wolfgang Kabsch and Chris Sander to standarize secondary structure assignment.

-Molmol is a molecular graphics program for displaying, analyzing, and manipulating the three-dimensional structure of biological macromolecules, with special emphasis on the study of protein or DNA structures determined by NMR.

- Rasmol and OpenRasMol are programs for molecular graphics visualization originally developed by Roger Sayle.

- PSI-BLAST - Position Specific Iterative Blast refers to a feature of BLAST 2.0 in which a profile (or position specific scoring matrix, PSSM) is constructed (automatically) from a multiple alignment of the highest scoring hits in an initial BLAST search.

- PDBSUP is a tool for superimposing protein structures.

- Deep View Swiss-PdbViewer is a tool for visualization and prediction of the protein structures.

-MODELLER is used for homology or comparative modeling of protein three-dimensional structures. The user provides an alignment of a sequence to be modeled with known related structures and MODELLER automatically calculates a model containing all non-hydrogen atoms.

Networking, systems and other

-Bonding (Port Trunking)interfaces on Linux is an interesting concept of merging network interfaces into groups in order to increase a capacity or a fault tolerance of the network connection.

-VLANs on Linux.It is a link to nice article that introduce in clear way the concept of Virtual Local Area Networking (VLANs) using Linux.
