Devel::Profile 1.04
Devel::Profile is a Perl module to tell me why my perl program runs so slowly. more>>
Devel::Profile is a Perl module to tell me why my perl program runs so slowly.
SYNOPSIS
perl -d:Profile program.pl
less prof.out
The Devel::Profile package is a Perl code profiler. This will collect information on the execution time of a Perl script and of the subs in that script. This information can be used to determine which subroutines are using the most time and which subroutines are being called most often.
To profile a Perl script, run the perl interpreter with the -d debugging switch. The profiler uses the debugging hooks. So to profile script test.pl the following command should be used:
perl -d:Profile test.pl
When the script terminates (or periodicly while running, see ENVIRONMENT) the profiler will dump the profile information to a file called prof.out. This file is human-readable, no additional tool is required to read it.
Note: Statistics are kept per sub, not per line.

Netprofiler 1.0.2
Netprofiler is a software that can write network settings into config files. more>>
Netprofiler is a software that can write network settings into config files.
Netprofiler saves the settings of network devices into files with appropriate names for each device into a folder with a name specified by the user.
These are called netprofiles. It is then easy to change the network settings to those saved in the profiles.
Netprofiler is released under the GNU Public License version 2 or any higher version if avaliable.
Enhancements:
- Added a checkif_root function to install.sh to make life easier for users who want to at least view the help for the installer.
- Added checks for hostx in case host from bind-utils isnt installed to resolv hostnames for get_defaultroute.
- Added masked filtering as a config file option. When enabled it excludes any devices that start with the device names in filtered.list. For example if eth appeared in filtered.list then no ethernet devices would be configured by netprofiler despite those devices being present in the profile that was being activated.
- Root permission checks are now only executed when activating a profile or generating one. This allows normal users to list profiles, see the --help messages, see the current settings etc.
- Added path checks for id. (used to be just /bin/id but added /usr/bin/id ).
- Changed default permissions for the netprofiler script to 755 to enable users to run it.
- Big thanks go to Bogdan Duda for spotting and fixing these bugs as well as writing the patch which included most of these features. Cheers!

Params::Profile is a Perl module for registering Parameter profiles.
SYNOPSIS
package Foo::Bar;
use Params::Profile;
### Single profile
Params::Profile->register_profile(
method => subroto,
profile => {
testkey1 => { required => 1 },
testkey2 => {
required => 1,
allow => qr/^d+$/,
},
testkey3 => {
allow => qr/^w+$/,
},
},
);
sub subroto {
my (%params) = @_;
return unlesss Params::Profile->validate(params => %params);
### DO SOME STUFF HERE ...
}
my $profile = Params::Profile->get_profile(method => subroto);
### Multiple Profile
Params::Profile->register_profile(
method => subalso,
profile => [
subroto,
{
testkey4 => { required => 1 },
testkey5 => {
required => 1,
allow => qr/^d+$/,
},
testkey6 => {
allow => qr/^w+$/,
},
},
],
);
sub subalso {
my (%params) = @_;
### Checks parameters agains profile of subroto and above registered
### profile
return unlesss Params::Profile->validate(params => %params);
### DO SOME STUFF HERE ...
}
Params::Profile provides a mechanism for a centralised Params::Check or a Data::FormValidater profile. You can bind a profile to a class::subroutine, then, when you are in a subroutine you can simply call Params::Profile->check($params) of Params::Profile->validate($params) to validate against this profile. Validate will return true or false on successfull or failed validation. Check will return what Data::FormValidator or Params::Check would return. (For Params::Check this is simply a hash with the validated parameters , for Data::FormValidator, this is a Data::FormValidator::Results object)

DBI::ProfileData can manipulate DBI::ProfileDumper data dumps.
SYNOPSIS
The easiest way to use this module is through the dbiprof frontend (see dbiprof for details):
dbiprof --number 15 --sort count
This module can also be used to roll your own profile analysis:
# load data from dbi.prof
$prof = DBI::ProfileData->new(File => "dbi.prof");
# get a count of the records (unique paths) in the data set
$count = $prof->count();
# sort by longest overall time
$prof->sort(field => "longest");
# sort by longest overall time, least to greatest
$prof->sort(field => "longest", reverse => 1);
# exclude records with key2 eq disconnect
$prof->exclude(key2 => disconnect);
# exclude records with key1 matching /^UPDATE/i
$prof->exclude(key1 => qr/^UPDATE/i);
# remove all records except those where key1 matches /^SELECT/i
$prof->match(key1 => qr/^SELECT/i);
# produce a formatted report with the given number of items
$report = $prof->report(number => 10);
# clone the profile data set
$clone = $prof->clone();
# get access to hash of header values
$header = $prof->header();
# get access to sorted array of nodes
$nodes = $prof->nodes();
# format a single node in the same style as report()
$text = $prof->format($nodes->[0]);
# get access to Data hash in DBI::Profile format
$Data = $prof->Data();

XML User Profiles 0.2.3
XML User Profiles is a system that allows for remote and transferable user accounts. more>>
XUP is an attempt to replace static per-site user accounts, which most present dynamic web sites use in absence of an easy to use and open/shared user account system. It allows people to use a single account or profile with many sites, or one of their existing user profiles on multiple other web sites.
It is best suited to so called "community" sites, where the account serves mainly for lax identification of people among each other. It does not stipulate strong authentication (while OpenID or LID can be used) and is therefore only useful for applications with mediocre security and privacy demands.
Chat and discussion sites are the main target, but profiles in different applications can often also be enriched with them. They are meant to get used secondarily (as alternative) to static/local user accounts.
The XML format of user profiles is extremely simple, as is the associated login service API. Both are outlined and explained in the introduction (HTML). The format is basically an XMLified vCard with a few additions targetted at online/web communities. It is easy to parse and generate and therefore also suitable for profile exchange or import.
Theres also a more authoritative RFC-style text version of the current proposal, which provides further hints and explanations for implementors. Future extensions will get listed in the project Wiki however (field names in the XUP format are not regulated).
This effort is quite new, and therefore only very few actual (real-world) implementations are known so far.
Some software, like discussion boards (which mostly suffer from spaghetti code), are of course hard to extent with XML User Profiles. Even those that abstract their internal user database and UI logic reasonably well can often be difficult to adapt. It is however expected that the more professional systems will sooner than later be XUP compatible.

KProf 1.4.2
KProf is a visual tool for developers, which displays the execution profiling output generated by code profilers. more>>
KProf is a visual tool for developers, which displays the execution profiling output generated by code profilers.
The output of profilers being usually difficult to read (beyond the flat profile information), KProf presents the information in list- or tree-views that make the information very easy to understand.
Main features:
- Flat profile view displays all function / methods and their profiling information.
- Hierarchical profile view displays a tree for each function / method with the other functions / methods it calls as subelements.
- Object profile view, for C++ developers, groups the methods in a tree view by object name.
- Graph view is a graphical representation of the call-tree, requires GraphViz to work.
- Method view is a more detailed look at an individual method - cross referenced.
- Recursive functions carry a special icon to clearly show that they are recursive.
- Right-clicking a function or method displays a pop-up with the list of callers and called functions. You can directly go to one of these functions by selecting it in the pop-up menu.
- The flat profile view provides an additional filter edit box to filter the display and show only the functions or methods containing the text that you enter.
- Function parameters hiding if the function name is unique (i.e. no different signatures)
- C++ template abbreviation (template parameters can be hidden)
- Automatic generation of call-graph data for GraphViz and VCG, two popular graph image generators.
- Diff mode support to compare two profile results.

Prasi 1.4
Prasi is a single-sign-on system for your Perl or PHP scripts, similar to MS Passport. more>>
Prasi is a Protocol for Remote Authentication and Shared Information.
Prasi is a single-sign-on system for your Perl or PHP scripts, similar to MS Passport. All your enabled services can save and share user profile data, and need not be one the same physical server. Available in 7 languages.
Prasi was originally written as an in-house tool to power our internal-use web applications. Due to one of the tools now being publically released (Wefis) it was decided to make Prasi an open-source project, despite its similarity to other existing open-source projects.
Prasi can be used on two levels. Firstly, it enables all CGI (Perl or PHP) scripts residing on any server to perform user management without the hassle of user management. One perl procedure call, and the browsing user is identified or challenged. The exact behaviour is easily customisable.
On the second level, Prasi is also able to keep track of user data (for example, profiles) and seamlessly share that profile information with other Prasi-enabled scripts. Using Prasi in this way gives scripts the power of mySQL and other types of databases without needing to manage the data themselves. Its quite nearly magic.
For the end user, one login, one password - all Prasi-enabled scripts instantly know who the user is and customise content accordingly.
Enhancements:
- This release adds minor bugfixes and increased compatibility with "cgi-bin"-type systems.
<<lessPrasi is a single-sign-on system for your Perl or PHP scripts, similar to MS Passport. All your enabled services can save and share user profile data, and need not be one the same physical server. Available in 7 languages.
Prasi was originally written as an in-house tool to power our internal-use web applications. Due to one of the tools now being publically released (Wefis) it was decided to make Prasi an open-source project, despite its similarity to other existing open-source projects.

Apcon 0.2.4 build 68
Apcon is a systemtray application for KDE. more>>
Apcon is based on IBMs Access Connections tool for the Thinkpads.
It is a systemtray application for KDE, that makes it very easy for users to specify and manage different network/connection profiles and connect/disconnect to/from them.
Furthermore a user can get several details and informations about a connection.
This can be very useful for people using notebooks on different locations. Under normal circumstances this should be the expected situation.
If the location will be changed, Apcon makes it possible to enable and configure the needed interface (to get a network connection) with just two clicks.
A profile can be created easily and quickly in four simple steps. An integrated wizard leads the user through this process.

Devel::DProf 19990108
Devel::DProf is a Perl code profiler. more>>
Devel::DProf is a Perl code profiler.
SYNOPSIS
perl5 -d:DProf test.pl
The Devel::DProf package is a Perl code profiler. This will collect information on the execution time of a Perl script and of the subs in that script. This information can be used to determine which subroutines are using the most time and which subroutines are being called most often. This information can also be used to create an execution graph of the script, showing subroutine relationships.
To profile a Perl script run the perl interpreter with the -d debugging switch. The profiler uses the debugging hooks. So to profile script test.pl the following command should be used:
perl5 -d:DProf test.pl
When the script terminates (or when the output buffer is filled) the profiler will dump the profile information to a file called tmon.out. A tool like dprofpp can be used to interpret the information which is in that profile. The following command will print the top 15 subroutines which used the most time:
dprofpp
To print an execution graph of the subroutines in the script use the following command:
dprofpp -T
Consult dprofpp for other options.
PROFILE FORMAT
The old profile is a text file which looks like this:
#fOrTyTwO
$hz=100;
$XS_VERSION=DProf 19970606;
# All values are given in HZ
$rrun_utime=2; $rrun_stime=0; $rrun_rtime=7
