Firefox: Run it on a host even if it you have it open on another – Bruce

Firefox setting for users who’s home dir lives on NFS – Bruce Duffy May 2013

Here’s how to tell Firefox that your homedir is sitting on an NFS filesystem:

This update (10.8) also fixes the following bug:

* In certain environments, storing personal Firefox configuration files
(~/.mozilla/) on an NFS share, such as when your home directory is on a
NFS share, led to Firefox functioning incorrectly, for example, navigation
buttons not working as expected, and bookmarks not saving. This update
adds a new configuration option, storage.nfs_filesystem, that can be used
to resolve this issue.

If you experience this issue:

1) Start Firefox.

2) Type “about:config” (without quotes) into the URL bar and press the
Enter key.

3) If prompted with “This might void your warranty!”, click the “I’ll be
careful, I promise!” button.

4) Right-click in the Preference Name list. In the menu that opens, select
New -> Boolean.

5) Type “storage.nfs_filesystem” (without quotes) for the preference name
and then click the OK button.

6) Select “true” for the boolean value and then press the OK button.
(BZ#809571, BZ#816234)

All Firefox users should upgrade to these updated packages, which contain
Firefox version 10.0.8 ESR, which corrects these issues. After installing
the update, Firefox must be restarted for the changes to take effect.

IDL COLOR PLOTTING WITH FANNING ROUTINES – YUPINGS 2014 UPDATE

Published by jweisber on 2014-08-25

I just realized that fsc_color is no longer available because the shared Coyote library was updated a couple weeks ago. So yes the library was updated from its previous early 2000s version. The development for fsc_color stopped at 2011 so now it is not in the library any more, with CGPlot as its successor.

Hence, if you are calling Coyote stuff in idl and found idl telling you that it does not exist, you might want to check the latest Coyote source code online to see if it has been expelled from the library.

Make Evince Display IDL PS Filename on Banner: JUST USE EVINCE!

Published by admin-joel on 2014-08-19

AS OF 2020 Sep (and I believe much earlier), using the graphics displayer EVINCE automatically puts filename on banner, and furthermore the following did not work with other viewers. Therefore consider the following to be “deprecated” (withdrawn) –jmw

To  actually use evince from the command line, type evince <filename> &

To actually use evince in a nautilus file manager, select (click on) the desired file, and go to
file>>open with>>evince

Commonly when one prints plots to a postscript from IDL and open it with evince(as we always do), the banner of the evince window perennially shows “Graphics Produced By IDL”, which is not helpful at all especially when you’re plotting a thousand plots and trying to compare them.

Hence a pair of IDL routines (OPENPS and CLOSEPS )can be called now to make the output PS file display the file name at the banner and to make the plotting to file process slightly less complicated. The way to call them is as follows:

OPENPS, blablabla.ps      //Before you plot anything. This will set the output device to blablabla.ps and by default color plot

[ DEVICE, FONT_SIZE=9]  //This is the optional part if you want anything about the graph beyond color, see IDL documentation on DEVICE for more

//information. Note that you may overwrite the color attribute here by saying DEVICE,/COLOR=PS

plot,bla

overplot.bla //Plot and add labels and do whatever as you like

CLOSEPS //When you’re done with one graph, simply call CLOSEPS, it will save the file for you and set the plotting device back to xwindows

WARNING: DO CLOSEPS BEFORE YOU OPENPS A NEW FILE. IN OTHER WORDS, EACH PLOT FILE MUST BE ENCLOSED BY A PAIR OF

OPENPS-CLOSEPS statement.

For more information, the code locates at /usr/share/astro/idlshare/locallib, or email huangy@carleton.edu.

tempo2,fftw3 and cfitsio setup

Published by admin-joel on 2014-08-13

TEMPO 2 is the newer pulsar timing package. FFTW3 is a fast fourier transformation library. CFITSIO is the NASA library for reading FITS format images. All of them are installed under $PSRHOME.  there’s another installation documenting file 00READMECarleton under that folder. FFTW3 and cfitsio are the dependencies for some of the tempo2 plugins and psrchive.

1. FFTW 3.3.4 is obtained from http://www.fftw.org/download.html,  unzip the tar file then

./configure –prefix=$PSRHOME/FFTW3/
sudo make
sudo make check
sudo make install

This will install the double precision FFTW3 library for TEMPO 2. However, the single-precision fftw
library that psrchive might require is not installed yet.

2.CFITSIO 3.370 is obtained from http://heasarc.gsfc.nasa.gov/fitsio/, unzip, cd, then

./configure –prefix=$SOFTWARE_DIR
sudo make shared
sudo make install

3. TEMPO2 is obtained by CVS anonymous checkout
cvs -z3 -d:pserver:anonymous@tempo2.cvs.sourceforge.net:/cvsroot/tempo2 co tempo2

The installation requires an amount of modification of config files (pgplot compilation flag, fixing bugs).
See 00REAMECarleton for details. But basically you do

./bootstrap
 setenv TEMPO2 $PSRHOME/tempo2/
 ./configure --prefix=$PSRHOME/tempo2/ --with-cfitsio-dir=$PSRHOME/cfitsio/ --with-fftw3-dir=$PSRHOME/FFTW3/ F77=f77
 sudo make && sudo make install
 sudo make plugins && sudo make plugins-install
