Free bin software for linux

Algorithm::BinPack is a Perl module that can efficiently pack items into bins.

SYNOPSIS

Algorithm::BinPack efficiently packs items into bins. The bins are given a maximum size, and items are packed in with as little empty space as possible. An example use would be backing up files to CD, while minimizing the number of discs required.

my $bp = Algorithm::BinPack->new(binsize => 4);

$bp->add_item(label => "one", size => 1);
$bp->add_item(label => "two", size => 2);
$bp->add_item(label => "three", size => 3);
$bp->add_item(label => "four", size => 4);

for ($bp->pack_bins) {
print "Bin size: ", $_->{size}, "n";
print " Item: ", $_->{label}, "n" for @{ $_->{items} };
}

METHODS

new

Creates a new Algorithm::BinPack object. The maximum bin size is specified as a named argument binsize, and is required. A fudge factor may be specified as a named argument fudge. If a fudge factor is specified, item sizes will be rounded up to a number divisible by the fudge factor. This can help keep items with similar sizes in order by their labels.

my $bp = Algorithm::BinPack->new(binsize => 4);
my $bp = Algorithm::BinPack->new(binsize => 100, fudge => 10);

add_item

Adds an item to be packed into a bin. Required named arguments are label and size, but any others can be specified, and will be saved. An optional bin argument can be used to manually put an item into the specified bin.

$bp->add_item(label => one, size => 1);
$bp->add_item(label => two, size => 2, desc => The second numeral);
$bp->add_item(label => zero, size => 3, bin => 0);
$bp->add_item(qw(label three size 3));
$bp->add_item(qw(label four size 4 random key));

prefill_bin

(Deprecated method) add_item now knows how to handle the bin argument directly, so this method is redundant.

pack_bins

Packs the items into bins. This method tries to leave as little empty space in each bin as possible. It returns a list of hashrefs with the key size containing the total bin size, and items containing an arrayref holding the items in the bin. Each item is in turn a hashref containing the keys label, size, and any others added to the item. If a fudge factor was used, each item will contain a key fudgesize, which is the size this item was fudged to.

for my $bin ($bp->pack_bins) {
print "Bin size: ", $bin->{size}, "n";

for my $item (@{ $bin->{items} }) {
printf " %-6s %-20sn", $_, $item->{$_} for keys %{ $item };
print " ---n";
}
}

HacBurn is a frontend to cdrtools/mpg321/ogg123 written with gtk2-perl.

HacBurn is a script written in perl using gtk2-perl. It allows a user to use cdrtools and a couple other console applications in a graphical interface to burn CDs.

It can currently burn iso/bin images and audio discs, it can make iso images and also copy CDs. If you have 2 optical drives on the fly copying is available.

Pipebench shows the current throughput and amount of data going through a pipe. It can be used to show the progress of a large md5sum process: cat bigfile | pipebench | md5sum.

Pipebench measures the speed of a pipe, by sitting in the middle passing the data along to the next process. Works on at least Linux, OpenBSD, NetBSD, Solaris and x86, Alpha, HPPA, Sparc and Sparc64.

Compiling

Just type make to compile.

Type make install to have pipebench be installed in /usr/local/bin

Psunami Bulletin Board is an Open Source alternative to the popular Ultimate Bulletin Board software, and aims for speed, ease of use, and a full feature set.

For installation, do the following:

1)Recursively copy everything from ./cgi-bin/ into your servers cgi-bin/ directory.

2)Recursively chown (chown -R) the psunami/ directory to the user that your web server uses (www-data on Debian, nobody on Slack, httpd on RHat-based systems (Ive been told that it is nobody on someRHat systems), wwwrun on SuSE. Anyone know what it is for others?) If you are unable to chown (eg. you are not the superuser) then make sure it is all readable/writable by the user (777 works, but is probably much too generous). Also do this to the psunami.conf file in cgi-bin.

3)Make psunami.cgi, psunami_admin.cgi, and psunami_moderate.cgi executable by the user that your web server uses. (chmod u+x *.cgi)

4)Change the paths to your perl executable if necessary. The paths are at the top of psunami.cgi, psunami_moderate.pl, and psunami_admin.cgi and default to /usr/bin/perl. Type which perl at a command prompt if you dont know where the executable is.

5)Run psunami_admin.cgi and create a new board. The initial login is psunami and the password is bulletin (no quotes).

6)Make sure that your mail program is configured properly in the preferences. It defaults to /usr/bin/sendmail.

7)Once you have created an account for yourself and given it admin rights, make sure you delete the psunami user.

h4xx0ri5e is a service menu which renames files to give them a more hackerish look.

Exemple:

hacker -> h4xx0r
hack -> h4xx
the -> teh
a, A -> 4
l, L -> 1
o, O -> 0
s, S -> 5

Hope you may have fun with it.

Installation:

just copy (i assume youve got kde in the standard place):
h4xx0r15e.desktop to ~/.kde/share/apps/konqueror/servicemenus (for yourself), or
to /usr/share/apps/konqueror/servicemenus/ (for everyone), and
h4xx0r15e.sh to one of the $PATH directories, f.ex. /usr/local/bin, or /usr/bin

Known problems:

doesnt work with filenames with spaces. sorry, i just dont feel like trying to fix it now since i know the whole thing is useless and pure fun, anyway.
