We suggest to consider computer viruses as this new specific form of life which is coming in the contact with our form of life. ... Computer life has been created by human being, the role of independent evolution of computer viruses seems to be still negligible. ...

The aim of this section of the course is to enable you to use simple computer programs to solve a variety of common astronomical tasks. ... I have (somewhat arbitrarily) decided to use Python for this course, because it seems to be gaining popularity fast for astronomical data handling, and because some of you will have encountered it at the ATNF course. ... We've put Python (plus all relevant libraries) on the Stromlo Linux computers moron and maggot. ... Now log in to moron (or maggot). ...

The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

... A well known problem with EOP prediction is that a prediction strategy proved to be the best for some testing period and prediction length may not remain as such for other period of time. In this paper we consider possible strategies to combine EOP predictions made using different analysis techniques to obtain a final prediction with the best accuracy corresponding to the least prediction error between input predictions. ...
