What do you do when you receive a "bad superblock" error on a USB or other Flash drive? Well, firstly you kick yourself for not backing up important data on said drive for the past nine days; you're old enough to know better than that. Secondly, you kick yourself for using that piece of rubbish called the FAT32 filesystem which was default for Windows 95, but is what every USB drive ships with because it's the last file format released by Microsoft that actually communicates with other operating systems, despite the fact that it's as buggy as hell and is prone to disaster.

From their website.
VAMP/VASP [Vienna Ab-initio Simulation Package] is a package for performing ab-initio quantum-mechanical molecular dynamics (MD) using pseudopotentials and a plane wave basis set. The approach implemented in VAMP/VASP is based on a finite-temperature local-density approximation (with the free energy as variational quantity) and an exact evaluation of the instantaneous electronic ground state at each MD-step using efficient matrix diagonalization schemes and an efficient Pulay mixing. These techniques avoid all problems occurring in the original Car-Parrinello method which is based on the simultaneous integration of electronic and ionic equations of motion. The interaction between ions and electrons is described using ultrasoft Vanderbilt pseudopotentials (US-PP) or the projector augmented wave method (PAW). Both techniques allow a considerable reduction of the necessary number of plane-waves per atom for transition metals and first row elements. Forces and stress can be easily calculated with VAMP/VASP and used to relax atoms into their instantaneous groundstate.
Or, in other words...

Body Language and Conversation
Conservative dressing in Indonesia consists of a collared shirt for men and long pants. Women are expected also to wear pants or skirts that go beyond the knee and tops which cover the shoulder. Shorts and t-shirts are accepted in tourist areas and bikinis on tourits beaches, but otherwise they are best avoided, and certainly must be avoided when visiting an Indonesian home or place of worship. Sarongs, short-pants and t-shirts are normally worn around the home. In Balinese Hindu temples, a sash should be worn around the waist.

Prepositions establish relationships between words and are therefore useful in building phrases. Some common examples in Bahasa Indonesia include the following:
At, In, On (all referring to place), use "Di".
At, In, On, For (all referring to time, use "Pada jam", "Dalam", "Pada", "Selama", respectively.
For (a purpose) use "Untuk"
From use "Dari"
Towards use "Ke"
Inside, Outside use "Di dalam", "Di luar", respectively
Since and Until use "Sejak", "Sampai", respectively
About and With use "Tentang" and "Dengan", respectively

Greetings and Responses
In any language basic introductions must be learned. Introductions in Indonesia may include a gentle handshake and the touching of the heart afterwards to indicate goodwill. Always use the right hand.
"Selamat" is the basic greeting word, derived from the Arabic "salam", meaning peace.
"Selamat pagi" (Good morning), "Selamat siang" (Good day, from about 11am to 2-3pm), "Selamat sore" (Good afternoon), "Selamat malam (good evening, after nightfall), "Selamat tidur" (good night, "tidur" = to sleep).

Whilst rote-learning should be avoided in most cases when learning a second language in some cases, as people learn sentences, not words, in some basic cases it is an effective way to ingrain knowledge. Specifically, basic pronunciation, the alphabet and numbers should be practised until they become second nature.

Further adventures in attempting to install Underworld 1.2 on Wexstan.
Previous instruction for installing Mesa largely work, but with the following exceptions.
Use a new directory name and run the configuration as modified...
mkdir -p /usr/local/mesa/7.4
... and discover a new and interesting failure.

Mesa (why does their website use frames?) is an open source 3D graphics library based on the OGL specification. It's been around since 1993 and is still in regular development, making it quite popular for scientific applications.
