bottom panel in unity

Friday, May 13th, 2011

in ubuntu natty 11.04 with unity, there is no bottom panel any more which shows the open windows etc. this can be changed following http://askubuntu.com/questions/39069/how-do-i-use-the-gnome-panel-in-unity:

  • Run gnome-panel in the terminal (Don’t close the terminal until finished with the instructions)
  • A Gnome Classic desktop will appear over unity
  • Remove the top panel for we can use the Unity panel
  • Add gnome-panel to Start with the System.

special characters in postscript

Monday, May 2nd, 2011

in the postscript files produced by FRIDA, there is a macro to insert special characters:

1
2
3
4
5
6
7
8
/grec {
   showif
   /Symbol findfont fontsize scalefont setfont
   } def
/endgr {
   showif
   regularfont setfont
   } def

so for example a small omega is produced by {() grec (w) endgr ()}.

it can be used to print special characters, using this map
a table of symbols accessable in postscript

take value of column times ten (that’s what the x means) and add the number of the column. example: degree sign: 26*10+0=260.

then use: {() grec (\260) endgr ()}

blog…

Saturday, April 30th, 2011

i’ve decided to delete the main page and replace it with the blog — it tended to be incomplete, and i found myself not using it but the sidebar and the search, anyway.

i’ll use the opportunity to advertise the free software foundation newsletter. you might have guessed already: it’s free! ;)
