okteta 4:4.3.3-0ubuntu1 (i386 binary) in ubuntu lucid

 Okteta is a simple editor for the raw data of files. This type of program is
 also called hex editor or binary editor.
 The data is displayed in the traditional view with two columns: one with the
 numeric values and one with the assigned characters. Editing can be done both
 in the value column and the character column. Besides the usual editing
 capabilities Okteta also brings a small set of tools, like a table listing
 decodings into common simple data types, a table listing all possible bytes
 with its' character and value equivalents, a info view with a statistic and a
 filter tool. All modifications to the data loaded can be endlessly undone or
 redone.

 This package is part of the KDE 4 utilities module.
