i am graduate student and my X colleague gave me this Fortran 77 program to run my result files with. She is no longer reachable. I compiled the following program with gfortran, it compiled well but, when i run it, gave me end of file error. My output file (which is the input file for this program (DFILE1) ) has about 78,000 lines of velocities of atoms (Vx, Vy, Vz with 1000 steps.. an example of some of the atom's velocities in the 1st step is given at the end of this program).

Fedora :: Cannot Set Time Of Clock

Jul 29, 2009

When installing I perhaps mistakingly told Fedora it should use the BIOS clock and now it shows the wrong time, 1 hour ahead of my time-zone GMT+0. If I try and go to the preferences and set the time the 'Advanced Options' one of which I need are grayed out, I need the 'Use local time source' option to be unchecked. Could somebody tell me a workaround or the command-line commands to tell it not to do this anymore?

Programming :: Calculate Length Of My Array?

Jun 30, 2010

I want to calculate length of my array, say Unix here.

Code:
[linux1@HMLINUX1 abc]$ declare -a Unix=('Debian' 'Red Hat' 'Suse' 'Fedora');
[linux1@HMLINUX1 abc]$
[linux1@HMLINUX1 abc]$ echo ${#Unix[@]}
5

This should be ideally 4, but somehow it is showing as 5. However, when I am removing the space as RedHat instead of Red Hat, it is working perfectly.

Code:
[linux1@HMLINUX1 abc]$ declare -a Unix=('Debian' 'Redhat' 'Suse' 'Fedora');
[linux1@HMLINUX1 abc]$ echo ${#names[@]}
4

Programming :: Calculate The Blade Offset In Python?

Dec 30, 2010

I'm using pyqt3 for my app and am lost on even how to attempt this task... On a vinyl cutter to have the blade pivot it must be offset from the center of the shaft it's on so say for example a .25mm offset would leave a .25mm unwanted vinyl attachment when the cutting is done. I somehow have to average or extrapolate that .25mm xy coordinate and add it to the hpgl plot file as a PUx,y; command? I have enclosed a simple sample file that has three images in it. In the corresponding hpgl file everything between the PU commands that are starting with PD are the code for that image (star for eg the pu to move to next image and then all PD for the next image and so on, so once the formula or procedure is figured out it can be applied to as many images there are in the file. Placing the new command at the head of each image PD group. Since there are absolute and relative cutters I enclosed the same exact plot for both types as the coordinates on relative can be negative numbers. Only PU and PD commands and a ";" as a command delimiter as sometimes many commands are on one line.The offset variable will come from a spinbox but .25 is good for an example.

Programming :: Sudoku - Calculate The Correct Box For A Given Square?

Apr 8, 2011

Im doing a sudoku-solver as a school assigment in Java. It is supposed to solve both 6x6, 9x9 and 12x12 boards.Im pretty much done with my algorithm(brute force), but I'm having a hard time figuring out how to calculate the right Box for a Square. I found this snippet:

Code:

// calculate BoardPos for index, where index is 0..80
void loadBoardPosFromIndex(BoardPos &pos, int index) {
pos.index = index;

[code]...

This works on 9x9 boards, but I really dont get the math behind this, and how I can create a generic rule for both 6x6, 9x9 and 12x12 boards.

Ubuntu :: Alarm Clock Program Goes Off?

Sep 24, 2010

I'm looking for an easy to use alarm clock program that I can suggest to new users. The two I have tried so far have fallen short of my expectations. "Alarm Clock" from the Ubuntu software repository starts out okay, but when the alarm actually goes off, getting it to stop seems pretty unintuitive. Click on the Alarm Clock icon, then click a Stop button in the new window that pops up. Sounds easy enough except that the icon used for "Stop" is just this grey square, so for users who are not familiar with linux or this program, it isn't even obvious that it is a button. I had one user actually uninstall the thing in order to get it to shut up. Preferably one should be able to silence the alarm by click on the alarm icon (or right clicking, if a 'doze' behavior is preferred) The other one I tried was alarm-clock-applet, which wants me to locate an alarm sound on my filesystem. Uh, no.

Does anyone know of a simple, basic alarm clock system that anyone can just sit down and immediately use without having to 'get in to the head' of the developer? Are the KDE alarms better? Am I missing something about either of these programs which would make them easier to use?

Fedora :: Clock - Can't Get Accurate Time On Systems

Jul 7, 2009

I have dual boot on my comp. Windows XP and Fedora 11 Now in both systems time zone is set to Belgrade ( which is my time zone), but when I setup clock in fedora to be, let's say 16.15h, then when I swich to windows it says time is 14.15h. When I setup in windows on 16.15h, and I swich to fedora, it says time is 18.15h. So I can't get accurate time on both systems in no way.

Fedora :: Show Clock To Civilian Time?

Nov 12, 2009

By default, Fedora 11 sets my clock to military time. For example it says 16:22. I would like it to show civilian time (or at least know how to do it) I logged into the clock settings and had to put in the root password, but couldn't find where you do this. If you scroll on the time for hours, it just goes from 0 to 23 and back, not to AM and PM like some others.

OpenSUSE :: Time / Clock Resets - Random On 11.3

Sep 3, 2010

I done searches for "clock" and found similar threads, but no real fix that is working for me. My clock resets when I boot into linux. It does not happen in windows or bios even on cold boots. The battery is replaced and good** the old battery was by all measures dead (0.6v), but still seemed to have enough power for the clock, since windows tested fine with it.

I have tryed setting it to local time, UTC.. etc... My timezone is GMT (london). "sudo /sbin/hwclock --systohc" Although I have windows, I do not use it except the few times to test this, so no conflict.

Ubuntu :: System Clock Will Not Set To Local Time

Aug 15, 2010

Try as I might I cannot seem to get the system clock to display local time. It looks like it's stuck on GMT. In the System>Administration>Time and Date I have my local time zone set correctly and also set to update automatically with an appropriate time server selected. It still displays my local time +5 hours (I'm central time, USA).
