Class::Adapter is a Perl implementation of the "Adapter" Design Pattern.

The Class::Adapter class is intended as an abstract base class for creating any sort of class or object that follows the Adapter pattern.

What is an Adapter?

The term Adapter refers to a "Design Pattern" of the same name, from the famous "Gang of Four" book "Design Patterns". Although their original implementation was designed for Java and similar single-inheritance strictly-typed langauge, the situation for which it applies is still valid.

An Adapter in this Perl sense of the term is when a class is created to achieve by composition (objects containing other object) something that cant be achieved by inheritance (sub-classing).

This is similar to the Decorator pattern, but is intended to be applied on a class-by-class basis, as opposed to being able to be applied one object at a time, as is the case with the Decorator pattern.

The Class::Adapter object holds a parent object that it "wraps", and when a method is called on the Class::Adapter, it manually calls the same (or different) method with the same (or different) parameters on the parent object contained within it.

Instead of these custom methods being hooked in on an object-by-object basis, they are defined at the class level.

Basically, a Class::Adapter is one of your fall-back positions when Perls inheritance model fails you, or is no longer good enough, and you need to do something twisty in order to make several APIs play nicely with each other.

What can I do with the actual Class::Adapter class

Well... nothing really. It exist to provide some extremely low level fundamental methods, and to provide a common base for inheritance of Adapter classes.
The base Class::Adapter class doesnt even implement a way to push method calls through to the underlying object, since the way in which that happens is the bit that changes from case to case.

To actually DO something, you probably want to go take a look at Class::Adapter::Builder, which makes the creation of Adapter classes relatively quick and easy.

Modem.pl is a small script that scrapes the web interface of a Motorola SURFboard cable modem for various status conditions like signal strength and signal to noise.
The results are sent to STDOUT where they can be easily piped into a log file. The modem values are also checked for reasonable operating ranges.
If the modem values are outside of reasonable operating ranges, results are also sent to STDERR. When run from a cron job, modem.pl can be used to monitor the condition of the cable service and notify someone before conditions cause service interruptions.
Main features:
- Captures operating conditions of a Motorola SURFboard cable modem.
- Runs interactively or from a scheduled job (cron)
- Output is formatted with a standard log time stamp when scheduled.
- Checks modem values for reasonable operating ranges.
- Errors and warnings are duplicated to STDERR.

Null IBBS is an Internet Bulletin Board System derived from an old snapshot of NullLogic Groupware.

Null iBBS uses cleartext password transmission. If security is a concern, use https!

This program is derived from an earlier version of Sentinel Groupware. This program also shares code with Null Webmail.

Installation

Null iBBS installation is a bit of a do-it-yourself process for the time being.

1) Move all the files and directories to a directory of your choice. /usr/local/ibbs might be a good default.

2) Edit the Makefile and check the mysql and pgsql dependencies.

3) Type make mysql or make pgsql to build the binary.

4) Create your database and use ibbsdb.mysql or ibbsdb.pgsql to create the database schema.

5) Edit etc/ibbs.cfg to match your configuration.

6) Make sure the files/ directory is writable by the user Null iBBS will be run as.

7) Run ./ibbs from bin/ (NOT AS ROOT!).

8) Curse the crappy install process, and give up in disgust (optional).

With luck, you now have Null iBBS running as a standalone server. It can also be run as a cgi by copying the binary and ibbs.cfg to your cgi-bin directory (works for me).

Nmap Parser is a module that implements a interface to the information contained in an nmap scan. It is implemented by parsing the xml scan data that is generated by nmap.
This will enable anyone who utilizes nmap to quickly create fast and robust security scripts that utilize the powerful port scanning abilities of nmap.
Enhancements:
- Parsing of distance information was added. Ignoring of taskend, taskbegin, and taskprogress information was added.
- Tests for nmap 4.20 were added.
- The license was changed to the MIT-style.
- The "always null" bug for the service->protocol call was fixed.

NullableTypes for .NET are a very reliable and efficient version of built-in value-types that can be Null. NullableTypes pass more than 800 differents test cases and have close-to-optimal efficiency as built-in value-types. They may be used every time you need to store a Null value in a .NET built-in value-type.

Types implemented by NullableTypes are: NullableBoolean, NullableByte, NullableInt16, NullableInt32, NullableInt64, NullableSingle, NullableDouble, NullableDecimal, NullableString and NullableDateTime.

Helper functions provide seamless integration with Windows and ASP.NET user controls and with ADO.NET.

NullableTypes will let you write code like this:

public sealed class Order{
public int OrderID {get {/*...*/}}
public int CustomerID {get {/*...*/}}
public NullableDateTime RequestedDeliveryDate {get {/*...*/}}
// remaining members elided for clarity
}

where RequestedDeliveryDate can be either NullableDateTime.Null or a valid DateTime value.

The property RequestedDeliveryDate.IsNull tests if the date is Null, and when it is not Null the property RequestedDeliveryDate.Value returns a valid DateTime value.

Device::Modem is a Perl extension created to talk to modem devices connected via serial port.

WARNING

This is BETA software, so use it at your own risk, and without ANY warranty! Have fun.

SYNOPSIS

use Device::Modem;

my $modem = new Device::Modem( port => /dev/ttyS1 );

if( $modem->connect( baudrate => 9600 ) ) {
print "connected!n";
} else {
print "sorry, no connection with serial port!n";
}

$modem->attention(); # send `attention sequence (+++)

($ok, $answer) = $modem->dial(02270469012); # dial phone number
$ok = $modem->dial(3); # 1-digit parameter = dial number stored in memory 3

$modem->echo(1); # enable local echo (0 to disable)

$modem->offhook(); # Take off hook (ready to dial)
$modem->hangup(); # returns modem answer

$modem->is_active(); # Tests whether modem device is active or not
# So far it works for modem OFF/ modem ON condition

$modem->reset(); # hangup + attention + restore setting 0 (Z0)

$modem->restore_factory_settings(); # Handle with care!
$modem->restore_factory_settings(1); # Same with preset profile 1 (can be 0 or 1)

$modem->send_init_string(); # Send initialization string
# Now this is fixed to AT H0 Z S7=45 S0=0 Q0 V1 E0 &C0 X4

# Get/Set value of S1 register
my $S1 = $modem->S_register(1);
my $S1 = $modem->S_register(1, 55); # Dont do that if you definitely dont know!

# Get status of managed signals (CTS, DSR, RLSD, RING)
my %signal = $modem->status();
if( $signal{DSR} ) { print "Data Set Ready signal active!n"; }

# Stores this number in modem memory number 3
$modem->store_number(3, 01005552817);

$modem->repeat(); # Repeat last command

$modem->verbose(1); # Normal text responses (0=numeric codes)

# Some raw AT commands
$modem->atsend( ATH0 );
print $modem->answer();

$modem->atsend( ATDT01234567 . Device::Modem::CR );
print $modem->answer();

Device::Modem class implements basic AT (Hayes) compliant device abstraction. It can be inherited by sub classes (as Device::Gsm), which are based on serial connections.

Backup Monitor is an rsync backup front-end with a Web interface, which emails reports with an attached summary or logfile.
Backup Monitors configuration system is simple to use and can back up single servers or entire server farms from a single machine.
Custom email tags can be used to sort responses in your mail reader.
Enhancements:
- This release adds MySQL support for logging, cleans up email notifications, and fixes null additions and a whitespace issue.
- The installer [install.php] fills in most config fields automagically for you.
- Log size rotation is configurable.
- PID check has been updated, and now relies on Unix::PID cleanliness.
- RSYNC STDERR is now redirected for email notifications.
