etymology of jargon

etymologically interesting

Anything self-referential is amusing (blame/praise starts with GEB - how can one describe systems purely if you have any use/reference of anything in that system in the description of the system - HAHAHAH!) like a joke or pun. Etymology of words about language, jargon: old french jargon garrire bird-chatter gargle. from http://www.etymonline.com/index.php?term=jargon

http://catb.org/jargon/html/introduction.html
http://catb.org/jargon/html/distinctions.html
"communication, and of inclusion, and of exclusion."
And for hacker jargon as a technical language there is a complex level of detail which does seperate it from being just a plainer slang. Not easy to learn/understand unless you learn the whole culture (shared consciousness), descriptive of complex/different ideas/models/thinking... which is very useful and important for facilitation of communication, quite like a real language.

Oh yeah! so elitist :) too.

"we have attempted to ensure that everyone's sacred cows get gored, impartially. Compromise is not particularly a hackish virtue, but the honest presentation of divergent viewpoints is."

This digression started with http://www.faqs.org/docs/jargon/H/hexadecimal.html
"correct term for base 10, for example, is ‘denary’"

   ~"etymologically pure"~   real live language   decimal style words   "too racy and amusing for stuffy IBM", (incorrect and inconsistent anyway! :))
2  binary                    binary
3  ternary or trinary        ternary
8  octonary                  octal                octaval
10 denary                    decimal              decimal

library-check.pl, postfix config to forward/relay mail to smtp server

1. Move across library-check.pl script from suse to ubuntu
2. enable mail from command-line and perl WWW::Mechanize script dependancies
3. solve postfix trouble (i.e. config postfix properly)
4. WAH! 5 + 6 books two accounts 5*23 + 6*29 days overdue. oops.

Bill Coleman new music

Went out with P&P to see Bill in Doyles Ruby Sessions last night.
He has sprouted quite a healthy beard. And gotten 15 red t-shirts plus red-striped
band trousers. :) Slightly poorer than before with working part-time but lots of time for music.
He had last two weeks off completely from work and played 4 I think brand-new shiny songs.
I was very impressed, crowd was entranced - completely silent a few times - noticable when the music goes softer. COOL. I get blown away with the sounds and it's tremendously emotionally engaging.

Hard to describe new songs.
One of them was made in 12hrs and making was filmed for someone and it's
sent in as a pilot to rte for a musicians-compose song in 12hours type tv series.
Two of them using the voice/music capture and playback and sing/play in loop with self thingumbyjig.

scales balancing puzzle check weights40.pl

see perl script weight40.pl

#!/usr/bin/perl

=head1 NAME

weights40.pl - check you can make each weight from 1 to 40 balance

=head1 DESCRIPTION

This doesn't solve the puzzle but does prove that the solution works.

The puzzle is you have a balance (bilancia in Italian).
And you can choose some unit weights to help weigh things. 
If you get any unit weight from 1 to 40 you need to be able to determine the weight.
 (You have to make the scales balance, you're not allowed to measure 
  it as lighter than w+1 and heavier than w-1 hence is w.) 
What is the minimum number of weights you can do this in ?

If the puzzle is told properly then you probably have to bring the 
balance and weights up a big mountain with dragons on top so you wish to use the absolute minimum 
number of weights (or possibly minimum weight of weights - is it the same answer I wonder?)

=cut 

my @weights = ( 1, 3, 9, 27 );

for(my $w=-1; $w<=41; $w++) {

    # brute force, try balance all permutations, weights on both sizes

    # try position of not there, left, right for each weight 
    my @weight_pos = ( 0, 0, 0, 0 );
    my $wi = 0;

    # print terrible message if not found otherwise might miss one 
    my $terribleness = "BAH! :( not good, no match for $w\n";
    my $found = 0;

    for($weight_pos[0]=0; $weight_pos[0]<3 && $found==0; $weight_pos[0]++) {
    for($weight_pos[1]=0; $weight_pos[1]<3 && $found==0; $weight_pos[1]++) {
    for($weight_pos[2]=0; $weight_pos[2]<3 && $found==0; $weight_pos[2]++) {
    for($weight_pos[3]=0; $weight_pos[3]<3 && $found==0; $weight_pos[3]++) {

	# start with $w always on left
	my $left_tot = $w;
	my $right_tot = 0;
	my @leftside = ( $w );
	my @rightside = ();

	# print '$#weights is ' . $#weights . " (number of elements in weights array)\n";

	# put weights on balance
	for($wi=0;$wi<=$#weights;$wi++) {

	    #print "dbg w=$w wi=$wi pos=$weight_pos[$wi]\n";

	    if ($weight_pos[$wi] == 1) {
		#printf "L";
		push @leftside, $weights[$wi]; 
		$left_tot += $weights[$wi];
	    } elsif ($weight_pos[$wi] == 2) {
		#printf "R";
		push @rightside, $weights[$wi]; 
		$right_tot += $weights[$wi];
	    }
	    #$ls += "(".$weights[$wi].) ";
	    #$rs += "(".$weights[$wi].) ";
	}

	
	#print "dbg w: $w, balance $left_tot = $right_tot, left: @leftside - right: @rightside\n"; 

	if ($left_tot == $right_tot) {
	    print "w: $w, balance $left_tot = $right_tot, left: @leftside - right: @rightside\n"; 
	    $terribleness = "";
	    $found = 1;
	    break;
	}

    }
    }
    }
    }

    print $terribleness;
}

perldoc is a good reference, (command-line interface to perl docs)
not on all machines but is on slaine
same stuff as is on web in lots of places of course:
http://perldoc.perl.org/perl.html

e.g. perldoc perl, perldoc perldoc (for table of contents)
perldoc perlsyn
perldoc perlre

-f or -q to get function documentation or search faq:

perldoc -f printf
perldoc -q while

After you know all that perldoc then you can start thinking about using perl modules! :D


To read perl documentation _inside_ perl scripts or modules just do e.g.:

perldoc weight40.pl

"Oh ye broke me cups and saucers"

I've set me playing the recorder of the tune of "cups and saucers" as ringtone for Mum :)
I started with "Moll Dubh" for Fionnuala.
Quite a striking mobile ringtone! :-o

Mum remembers her dad singing this chorus, and only the chorus:

Oh ye broke me cups and saucers
Oh ye did ye rogue, oh ye did ye rogue
Oh ye broke me cups and saucers
Oh ye did ye rogue, oh ye did ye rogue

Much grepping of internet reveals those lyrics are nowhere!
Maybe on an album by Bobby Gardiner - The Clare Shout - song The Kerry Cow, Cups and Saucers
http://www.thesession.org/recordings/display/2330
Someone says on comments "It's called Cups and Saucers on Bobby Gardiner's album "The Clare Shout". He lilts the tune and runs it into the song "Cups and Saucers" (of the same tune).
Maybe that is song eilzab is talking about."

thesession.org seems to be quite a good source for information on irish tunes.
lyrics, sheet music and ABC music
http://www.thesession.org/tunes/display/1123
Also known as "Bhiosa La I BPort Lairge", Cups And Saucers, False Knight On The Road, The False Knight On The Road, I'll Cloot My Johnny's Breeches, Let's Pet The Pope, Little May Cullinane, O, I Courted A Farmer's Daughter, Port Lairgè, Portlairge, Portláirge, Dashing White Sergent, White Cockade

And in last.fm/youtube can find various renditions of "The False Knight on the
Road" ... and one or two of them have the same tune.
