Hi Neo...

Even the best written code can be hard to understand after we have not touched it for a month or two, let alone a year or more.
Yup, I often do a search for something and come across an upload I have written and totally forgotten about. I read it and think did I actaully write that?

So, I learned the hard way many years ago not to write "fancy one liners" and write well documented code and scripts.
Going slightly off topic here with the second quote I was on a Python ML, (they were so obnoxious that I have long since left), and the big guns on there said there was no need to add comments as it was easy to work out what a python script does. I gave them this challenge:-
(Before reading the answer I wonder if the Python experts on here can work out what it does?)
Code:
# SomeSound.py

audio=file('/dev/dsp', 'wb')
def main():
	for a in range(0,25,1):
		for b in range(15,112,1):
			for c in range(0,1,1):
				audio.write(chr(127+b)+chr(127+b)+chr(127+b)+chr(127+b)+chr(127-b)+chr(127-b)+chr(127-b)+chr(127-b))
		for b in range(112,15,-1):
			for c in range(0,1,1):
				audio.write(chr(127+b)+chr(127+b)+chr(127+b)+chr(127+b)+chr(127-b)+chr(127-b)+chr(127-b)+chr(127-b))
main()
audio.close()

NAME
send-uucp - Send Usenet articles via UUCP SYNOPSIS
send-uucp [site ...] DESCRIPTION
The send-uucp program processes batch files written by innd(8) to send Usenet articles to UUCP sites. It reads a configuration file to control how it behaves with various sites. Normally, it is run periodically out of cron to put together batches and send them to remote UUCP sites. It makes it possible to reduce bandwidth usage and to send news to remote UUCP sites which cannot receive a real-time feed (for instance if they are over dial-up connections). OPTIONS
Any arguments provided to the program are interpreted as a list of sites specified in send-uucp.cf for which batches should be generated. If no arguments are supplied then batches will be generated for all sites listed in that configuration file. CONFIGURATION
The sites to which articles are to be sent must be configured in the configuration file send-uucp.cf in pathetc as set in inn.conf. Each site is specified with a line of the form: site[:host[:funnel]] [compressor [maxsize [batchtime]]] site The news site name being configured. This must match a site name from newsfeeds(5). host The UUCP host name to which batches should be sent for this site. If omitted, the news site name will be used as the UUCP host name. funnel In the case of a site configured as a funnel, send-uucp needs to flush the channel (or exploder) being used as the target of the funnel instead of flushing the site. This is the way to tell send-uucp the name of the channel or exploder to flush for this site. If not specified, default to flushing the site. compressor The compression method to use for batches. This should be one of "bzip2", "compress", "gzip" or "none". Arguments for the compression command may be specified by using "_" instead of spaces. For example, "gzip_-9". The default value is "gzip". maxsize The maximum size in bytes of a single batch before compression. The default value is 500000 bytes. batchtime A comma separated list of hours during which batches should be generated for a given site. When send-uucp runs, a site will only be processed if the current hour matches one of the hours in batchtime. The default is no limitation on when to generate batches. Fields are separated by spaces and only the site name needs to be specified, with defaults being used for unspecified values. If the first character on a line is a hash sign ("#") then the rest of the line is ignored. EXAMPLE
Here is an example for the send-uucp.cf configuration file: zoetermeer gzip 1048576 5,18,22 hoofddorp gzip 1048576 5,18,22 pa3ebv gzip 1048576 5,18,22 drinkel bzip2 1048576 5,6,18,20,22,0,2 manhole compress 1048576 5,18,22 owl compress 1048576 able pern::MYFUNNEL! This defines eight UUCP sites. The first three and the last two use "gzip" compression, the fourth site ("drinkel") uses "bzip2" and the remaining sites ("manhole" and "owl") use "compress". The first six use a batch size of 1 MB, and the two last sites ("able" and "pern") use the default of 500,000 bytes. The "zoetermeer", "hoofddorp", "pa3ebv", and "manhole" sites will only have batches generated for them during the hours of 05:00, 18:00, and 22:00, and the "drinkel" site will only have batches generated during those hours and 06:00, 20:00, 00:00, and 02:00. There are no restrictions on when batches will be generated for "owl", "able" and "pern". The "pern" site is configured as a funnel into "MYFUNNEL!". send-uucp will issue "ctlinnd flush MYFUNNEL!" instead of "ctlinnd flush pern". As for the newsfeeds file, the usual flags used for a UUCP feed are "Tf,Wnb". Here is a typical entry for "zoetermeer", where the batching is kept between 4 KB and 1 KB: zoetermeer :*,!junk,!control,!control.*/!foo :Tf,Wnb,B4096/1024: FILES
pathbin/send-uucp The Perl script itself used to create news batches from the outgoing files. pathetc/send-uucp.cf The configuration file which specifies a list of sites to be processed. HISTORY
