Games::Tournament::RoundRobin is a Perl module for Round-Robin Tournament Schedule Pairings.

SYNOPSIS

$schedule = Games::Tournament::RoundRobin->new;

$pairings = $schedule->indexesInRound($roundm);
$round = $schedule->meeting($member1, [$member2, $member3]);
...

Every member of a league of 2n players can be paired with every other member in 2n-1 rounds.

If the league members are (Inf, 1 .. 2n-1), then in round i, i can be paired with Inf, and a can meet b, where a+b = 2i (mod 2n-1).

METHODS

new

Games::Tournament::RoundRobin->new( v => 5, league => [Ha, Be, He])
Games::Tournament::RoundRobin->new( league => {A => $a, B => $b, C => $c})
where v (optional) is the number of league members, and league (optional) is a list (or a hash) reference to the individual unique league members. One of v, or league (which takes precedence) is necessary, and if league is not given, the members are identified by the numbers 0 .. n-1.

If the league is a list (or hash) of n objects, they should be instances of a class that overloads both string quoting with a name method and arithmetical operations with an index method. The index method, called on the n objects in order, should return the n numbers, 0 .. n-1, and in that order if they are presented as an array. If they are presented as a hash, the hash is stored internally as an array and the keys are discarded.

If the league is a list of strings or numbers, indexes are constructed for the values on the basis of their positions in the list, and if a hash of strings or numbers, on the basis of the lexicographic order of their keys. Each string is expected to be unique.
If n is odd, an additional n-1, Bye or object (a Games::League::Member object, by default) member, depending on the type of the first member in the league, is added at the end and n is increased by 1.
indexesInRound

$schedule->indexesInRound($m)

Returns an array reference of the pairings in round $m. This method is useful if you are using numbers to represent your league members. It is not so useful if you are using strings or objects and you dont know their index numbers. Positions in the array represent members. The values represent their partners. Each member is thus represented twice.

roundsInTournament

$t = $schedule-> roundsInTournament;
$round1 = $t[0];
$inRound1FourthWith = $t->[0]->[3];
$inLastRoundLastWith = $$t[-1][-1];

Returns, as a reference to an array of arrays, the pairings in all rounds of the tournament. This method is useful if you are using the algorithm indexes.
partner

$schedule->partner($member, $m)

Returns the partner of $member in round $m.

membersInRound

$schedule->membersInRound($m)

Returns an hash reference of the pairings in round $m. This method is useful if you are using strings or objects. Keys in the hash represent league members. If the league members are objects, their names are used as keys. If 2 names are the same, the names are changed to $name.1, $name.2 etc. The values are their partners. Each player is thus represented twice.

memberSchedule

$schedule->memberSchedule($member)

Returns, as an array reference, the partners who $member is matched with in the order in which they meet, ie round by round.

meeting

$schedule->meeting($member,$partner)

Returns the rounds (TODO and the venue) at which $member meets $partner.

meetings

$schedule->meetings($member1,[$member2,$member3,...])

Returns, as an array reference, the rounds (TODO and the venue) at which $member1 meets $member2, $member3, ...

index

$schedule->index($member)

Returns $members index, the number which is used to pair it with other members. The index is the position, 0..n-1, of the $member in the league argument to the constructor (if an array) or the constructed array (if a hash.)
If $member is not a member of the array, or is itself an index, undef is returned.

member

$schedule->member($index)
$schedule->member($name)
$bye = $schedule->member( $schedule->size-1 )

Returns the member represented by $index, a number which ranges from 0..n-1, or by $name, a string. If there is no such member, undef is returned.

partners

$schedule->partners($index)
$schedule->partners($name)

Returns an array reference of all the partners of the $indexed or $named member, in index order, or the order in the league argument.

realPartners

$schedule->realPartners($index)

Returns an array reference of all the partners of the $indexed member, excluding the Bye member. Dont use this if you have no Bye member, as it just leaves off the last member.

size

$schedule->size

Returns the number of members in the round robin. Sometimes this may not be the same as the number of league members specified, because the array of league members takes precedence if supplied, and a bye is added if the number is odd.

rounds

$schedule->rounds

Returns the number of rounds in the round robin. This equals the number of league members, minus 1.

fping is a ping like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping.

Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion.

If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

Problem and Issues:

With a large a number of IP addresses in use, its becomes more and more time consuming to check on which IP addresses are actively in use, and which critical machines (routers, bridges, servers, etc) are reachable. One example is we have a program which goes through all of our routers arp caches looking for IP addresses that are in use. After finding a list of IP addresses that arent in any arp caches fping can then be used to see if these IP addresses really arent being used, or are just behind the routers. Checking 2500 hosts (99% of which are unreachable) via ping can take hours.

fping was written to solve the problem of pinging N number of hosts in an efficient manner. By sending out pings in a round-robin fashion and checking on responses as they come in at random, a large number of hosts can be checked at once.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

mergelog provides a fast tool to merge HTTP log files by date.
mergelog is a small and fast C program, which merges HTTP log files by date in Common Log Format (Apache default log format) from Web servers, behind round-robin DNS.
It has been designed to easily process huge logs from highly stressed servers, and can manage gzipped files.
Enhancements:
- dont abort anymore on corrupted log lines
- set BUFFER_SIZE value to 32Ko
- fixed a major bug on a broken month initialization
- corrections on manpages
- fix in configure.in to abort if zlib is not present
- fixed a potential segmentation fault on malformed log lines
- autoconf compliant thanks to Igor Genibel

Ever wanted cute little penguins walking along the tops of your windows? Ever wanted to send an army of cute little penguins to invade the screen of someone else on your network? Probably not, but why not try this program out anyway - its free (licensed under the GNU GPL).
Xpenguins makes cute little penguins fall from the top of your screen and walk on the top of your windows under X11.
You need something that runs the X Window System (Linux, Unix etc), and have the ubiquitous XPM library installed.
Enhancements:
- The squish option: kill toons with your mouse!
- The themes Bill (images from XBill) and Big Penguins.
- The ability to run several themes simultaneously.
- Redraws erased desktop icons.

Class::ArrayObjects is a Perl utility class for array based objects.

SYNOPSIS

package Some::Class;
use Class::ArrayObjects define => {
fields => [qw(_foo_ _bar_ BAZ)],
};

or

package Other::Class;
use base Some::Class;
use Class::ArrayObjects extend => {
class => Some::Class,
with => [qw(_zorg_ _fnord_ BEZ)],
import => 1,
};

This module is little more than a cute way of defining constant subs in your own package. Constant subs are very useful when dealing with array based objects because they allow one to access array slots by name instead of by index.

phpQLAdmin is designed primarily for administration of a QmailLDAP user database, but also has (local/remote) EZMLM management, Bind9/LDAP (using the LDAP SDB driver), QmailLDAP/Controls and Apache Web server management abilities (using the mod_cfg_ldap module).
Version restrictions:
- Lots of Bind9 manager fixes (now supports AFSDB and round-robin pointers).
- Spelling errors in the use of some defines which led to broken user login and creation were fixed.
- The always-broken session handling was fixed.
- Some hardcoded attributes were replaced with corresponding (already existent) defines.
Enhancements:
- This is almost a complete rewrite of the automount manager.
- Small fixes were made in regard to deleting DNS host(s) when removing a Web server virtual host.
- The changing of a record type (from CNAME to A record for example) in the DNS manager was fixed.
- Copying or moving a virtual host from one physical Web server to another is supported.
- A long-standing problem was finally fixed regarding the initial folded branch tree in Opera.

Sound Studio is a Tcl/Tk application written by Paul Sharpe as his third year individual project, for which he received the Microsoft Prize for Software Engineering. It was subsequently improved by Robin Whitehead.

It enables recording, playback and simple cut & paste editing of sound files of diverse formats on a PC equipped with a soundcard and the OSS (formally VoxWare) sound drivers.

It uses Lance Norskogs Sox for format conversion; the version weve used is bundled together with this software in its entirety to prevent incompatibility problems, although you should try it with your own sox if you have a more recent one.

Sound Studio is now "finished", but no doubt there are loads of bugs still to be found and features to be added.

SuperShaper-SOHO is a traffic shaping setup for DSL connections which prioritizes VoIP and interactive traffic and makes sure P2P traffic doesnt saturate your uplink.
IPCop 1.3 and newer is known to work and is the preferred deployment setup. Firstly, be sure to disable the integrated traffic shaper in IPCop 1.4 if you use SuperShaper-SOHO.
