. rm filename: No such file or directory . The file or directory you are trying to copy does not exist. usage: rm [-rif] file ... You have used a non-existent option or you have failed to give a filename or directory_name . rm: override protection 600 for filename ? y . rm: filename not removed: Permission denied . You don't have permission to remove this file or directory. Most likely you're trying to erase a system file or another user's file.

A problem, that can arise when moving from Fortran 77 to Fortran 90, is dependent on a usual deviation from the standard, and has to do especially with user programs. ... With many Fortran 77 implementations we wrote PROGRAM TEST REAL X WRITE(*,10) 10 FORMAT('Give X = ',$) READ(*,*) X WRITE(*,*) X END In Fortran 90 we use "non-advancing I/O" instead. ... In some old Fortran dialects the statement TYPE was used to write on a typewriter terminal and PRINT was used to write on the line printer. ...

For all keywords that contain a red and a blue value, the blue value comes first. ... The full pathname, but without the trailing "b.fit" and "r.fit", that would be given to the next exposure if the basename argument is not given to the expose command. ccdHeaters=float,float . ... bluelambda2=float [M] . The center wavelength for the given grating: the 1 or 2 indicates the grating bay. The bluelambda and redlambda keywords match one set of these, depending on the position of the turret. ...

... I do have a problem with the realtime capabilities of Linux. I wrote a loadable driver which uses the RealTimeClock to generate periodic interrupt at a frequency of 1024Hz. With each interrupt the driver increments an internal counter. The 'read' function of the driver returns simply that counter. Next I wrote a realtime task (with the highest priority) which read that RTC continuously. This tasks checks if the read counter is incremented by one between two read calls. ...

The effect of an equilibrium flow on resonant absorption of linear MHD waves in cylindrical magnetic flux tubes is studied in compressible viscous MHD. ... A parametric analysis shows that there are values of the equilibrium velocity field for which the absorption rate becomes zero, even for rather small velocity shears. ... For other values of the equilibrium flow we find that the resonant absorption can be strongly enhanced, even up to total absorption of the incoming wave. ...

... Please note the following problems and workarounds: . ... Arrow keys . Arrow keys are used in SAOtng to move the mouse or markers. ... Unfortunately, error messages are generated if both sets are defined in the SAOtng code but are not supported by X. To get around this problem, we have added the -kbprefix command switch (and the SAOTNG_KBPREFIX environment variable) to SAOtng. This switch allows you to specify which arrow keys you want to use (assuming your version of X supports both). ...

... This article is part of the LWN Porting Drivers to 2.6 series . This article serves as a sort of final resting place for various small changes in the kernel programming API which do not fit elsewhere. The kdev_t type has been removed from the kernel; everything which works with device numbers should now use the dev_t type. ... Consider using these while fixing your code; the next time the type of i_rdev changes, you will be happier. ... Driver porting: miscellaneous changes, designated inits . ...

The revision of the MASS/DIMM star catalogue N. Shatsky, V. Kornilov March 16, 2008 Abstract The compilation of the (updated) version of the MASS (MASS/DIMM) device target catalogue is described. ... Then the list was cleaned according to following criteria: I. Remove stars too faint for a MASS device. ... Here the color equation of the Sternb erg device was taken: M AS S mag = V mag + 0.45 (B - V ); stars with M AS S mag > 3.2 were removed. ... This was made based on the GCVS4.2 catalogue data. ...

... Next: Star Finding and Up: Image Restoration and Previous: Multiresolution and Astronomical . ... Design improvements continue to be made in the filter developed using mathematical morphology principles for the Infrared Astronomical Satellite ( IRAS ) images. The purpose of this filter is to eliminate Galactic cirrus emission from extragalactic fields. ... With an appropriate normalization, the filter curve was applied to each pixel in the image to remove the Galactic cirrus. ...

Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... A most promising problem is to investigate the interaction of two VHF powerful radiowave beams in the ionosphere, whose difference frequency is equal to the plasma frequency in some ionospheric area (that is, the difference frequency is taken in the range 1-8 MHz). ... Two-frequency interaction effects are based on radiowave non-linear mixing, which is rather complicated when describing and modelling the experiment. ...

... For the past years I have been working on the problem of synthesis of light curves of close binary systems, consisting of a normal star and a compact object (point object with fixed X-ray luminosity). ... Possible existence of a
