Today, it's just links and information, I came across recently.


If you set the environment variable BLOCK_SIZE like this:

     BLOCK_SIZE=\'1

Then the GNU  coreutils  show  a  thousands  separator  in  large
numbers, like generated by `ls -l' or `du -s'.

Of course, you could supply `-h' to these commands, but  then  it
is  difficult  to  spot  the  magnitude  of  the numbers at first
glance.  You need to look at the unit prefixes. By  leaving  `-h'
out,  you  see  the  magnitude  of the number at once. BLOCK_SIZE
helps you to count the digits in this case.

I haven't investigated deeper, but it seems as if BLOCK_SIZE is a
GNUism. Hence I'm not sure if I should go for it.

I found BLOCK_SIZE on [0].  There's also this  interesting  usage
of abiword, which I should try out (in German):

     Konvertieren von Textfiles mit AbiWord

     Mit AbiWord lassen sich Textdateien  ganz  einfach  auf
     der Kommandozeile wandeln:

          abiword --to=pdf document.doc

     Wandelt beispielsweise eine Microsoft Word-DOC Datei in
     das  PDF-Format  um. AbiWord kennt eine ganze Reihe von
     Dateiformaten, z.B. abw, txt, rtf und html.

          abiword --to=txt --exp-props="encoding:utf-8" test.wri

     Abiword  kann  auch  Zeichensaetze   konvertieren.   Im
     Beispiel  wird  eine  Textdatei  von Windows nach Linux
     UTF8 gewandelt.

     Wenn man Skript gesteuert  mittels  AbiWord  eine  neue
     leere RTF-Datei erstellen moechte, oeffnet sich AbiWord
     mit "unbekannt0". Als Workarround dazu in einem Skript:

          echo "x" > $name.txt
          abiword --to=rtf $name.txt
          abiword $name.rtf

     So laesst sich eine neue RTF-Datei skriptgesteuert  mit
     AbiWord  anlegen. Das x am Dateibeginn muss man in Abi-
     word noch loeschen.


Then, there's Pentadactyl [1], a (it seems) not so fat-grown Vim-
perator.  I should compare them soon.


This [2] shows the magnitudes of size, through time in  computing
well.  Understanding these differences in size is a motivation to
value small software.


And here [3] the railway and telegraph lines at about 1900.

That should do it for now.
