Statistics::Forecast 0.3


Statistics::Forecast is a Perl module that calculates a future value. more>>
Statistics::Forecast is a Perl module that calculates a future value.

This is a dummy Oriented Object module that calculates a future value by using existing values. The new value is calculated by using linear regression.

SYNOPSIS

use Statistics::Forecast;

Create forecast object

my $FCAST = Statistics::Forecast->new("My Forecast Name");

Add data

$FCAST->{DataX} = @Array_X;
$FCAST->{DataY} = @Array_Y;
$FCAST->{NextX} = $NextX;

Calculate the result

$FCAST->calc;

Get the result

my $Result_Forecast = $FCAST->{ForecastY);

INTERNALS

The equation for Forecast is:
a+bx, where x is the predicted value and
_ _
a = y + bx

b = sum((x+x)(y-y))/sum(x-x)**2

METHODS

new

Receives a forecast name, only to remember and returns the blessed data structure as a Statistics::Forecast object.
my $FCAST = Statistics::Forecast->new("My Forecast");

calc

Calculate and return the forecast value.
$FCAST->calc;

dump

Prints data for debuging propose.
$FCAST->dump;

SumX

Returns the sum of X values.
my $SumOfX = $FCAST->{SumX};

SumY

Returns the sum of Y values.
my $SumOfY = $FCAST->{SumY};

SumXX

Returns the sum of X**2 values.
my $SumOfXX = $FCAST->{SumXX};

SumXY

Returns the sum of X * Y values.
my $SumOfXY = $FCAST->{SumXY};

AvgX

Returns the average of X values.
my $AvgX = $FCAST->{AvgX};

AvgY

Returns the average of Y values.
my $AvgY = $FCAST->{AvgY};

N

Return the number of X values.
my $N = $FCAST->{N};

EXAMPLE

use Statistics::Forecast;

my @Y = (1,3,7,12);
my @X = (1,2,3,4);

my $FCAST = Statistics::Forecast->new("My Forecast");

$FCAST->{DataX} = @X;
$FCAST->{DataY} = @Y;
$FCAST->{NextX} = 8;
$FCAST->calc;

print "The Forecast ", $FCAST->{ForecastName};
print " has the forecast value: ", $FCAST->{ForecastY}, "n";

Forecastfox 0.9.5.2

Forecastfox 0.9.5.2


Forecastfox is a Firefox extension to get international weather forecasts from AccuWeather.com. more>>
Forecastfox is a Firefox extension to get international weather forecasts from AccuWeather.com, and display it in any toolbar or statusbar with this highly customizable and unobtrusive extension.

Why the switch from Weather.com to AccuWeather.com?

Several factors contributed to us switching our data provider from Weather.com to Accuweather.com. The "Terms of Use" for the feed from Weather.com, was very restrictive. It kept us from implementing some of the things we hope to implement. They had also warned us that they were changing the feed and that we were in breach of the license (25,000 users max on the public XOAP weather.com feed). They offered another feed we could use, which would have limited the amount of data we received. At the same time several companies were contacting us about using their data. Accuweather.com was the most responsive, and provided us with greatest flexibilty and room to grow.

Please note that version 0.7.5 and higher "pings" our server when it is installed or uninstalled. No information is sent other than what version is being installed or uninstalled, and on what program (Mozilla vs Firefox). We simply increment a value in a database everytime it gets pinged so that we can have a rough estimate of the number of Forecastfox users. You can see the statistic page that we use at http://forecastfox.ensolis.com/logs/status.php. By knowing how many users we have and how many users upgrade, we will have a better idea of what we need to work on. For example, we will know if we should spend time supporting Mozilla and Netscape, and if we need to support migrating/upgrading from early versions. Thank you for understanding.

MySQL PHP to Posgres Converter 0.94

MySQL PHP to Posgres Converter 0.94


MySQL PHP to PostgreSQL is a program that takes a php page that uses mysql calls and changes them into PostgreSQL calls. more>>
MySQL PHP to PostgreSQL is an application that takes a php page that uses mysql calls and changes them into PostgreSQL calls.
This allows any website (if it converts properly) that was written in PHP for MySQL to run as a website written to run on PostgreSQL.
- Step 1: Download and uncompress
To uncompress simply type: tar xvzf mysqlphp2postgres.tar.gz
If youre on a non-GNU system you might have to type: gzip -dc mysqlphp2postgres.tar.gz | tar xvf -
- Step 2: Compile
To compile simply type: make
If youre on a non-GNU system youll have to edit the make file to change the compiler to cc instead of gcc
- Step 3: Install
Type: make install
This will simply copy the binary file to /usr/local/bin/
- Step 4: Convert
Type: mysqlphp2postgres inputfile.php outputfile.php
The input file is the php page that uses mysql. The outfile is the page you want to create. You will probably need to tell mysqlphp2postgres the name of the postgreSQL database since mysql_select_db doesnt translate. You can do this by using a -d switch. So if, for example, the database youre connecting to is called blah, you could type: mysqlphp2postgres -d blah inputfile.php outputfile.php
Problems:
I have had the following problems from using this program:
MySQL has a lot more functions in PHP than PostgreSQL that do more things. I havent had a problem with any unsupported functions in my programs, but someone probably will. If you want to help write code for this to support those functions (if thats even possible) feel free to help.
Enhancements:
- Fixed some stuff.
- Cleaned up some code.
- This program now produces code optomized for PHP 4.1.0 and above.

Gem to rpm converter 0.5.1

Gem to rpm converter 0.5.1


Gem to rpm converter creates an RPM spec file from a Ruby gem. more>>
Gem to rpm converter creates an RPM spec file from a Ruby gem. The project uses the gem metadata to fill out most of the information needed for building an RPM containing the gem.

Usage:

Run gem2rpm --help for options

At its simplest, download a gem (lets call that file GEM) and run

gem2rpm $GEM

This will print an rpm spec file based on the information contained in the gems spec file. In general, it is necessary to edit the generated spec file because the gem is missing some important information that is customarily provided in rpms, most notably the license and the changelog.

Rather than editing the generated specfile, edit the template from which the specfile is generated. This will make it easier to update the RPM when a new version of the Gem becomes available.

To support this process, it is recommended to first save the default template somewhere:

gem2rpm -T > rubygem-GEM.spec.template

Now, edit the template and then run gem2rpm to generate the spec file using the edited template:

gem2rpm -t rubygem-GEM.spec.template > rubygem-GEM.spec

With that, you can now build your RPM as ususal. When a new version of the gem becomes available, you should edit the saved template and rerun gem2rpm over it.

Template Details:

The template is a standard erb file; there are three main variables available in the template file:

format - The Gem::Format for the gem
spec - The Gem::Specification for the gem (the same as format.spec)

Conventions:

A typical source RPM for a gem should consist of three files: the gem file itself, the template for the spec file and the spec file. To ensure that the template will be included in the source RPM, it must be listed as one of the sources in the spec file.

The resulting rpms should follow the naming convention rubygem-$GEM where GEM is the name of the packaged gem. The default template also makes sure that the resulting package provides ruby($GEM), according to general packaging conventions for scripting languages

C to C++ is a Python script that converts C code to C++ code. more>>
C to C++ is a Python script that converts C code to C++ code.

The main program is ctocpp.py that performs successive stages for converting C to C++. A script, ctocpp gives it as parameter to the python interpreter with options you add.

The archive also includes scripts that may help you:

- mover.py changes the location of a project.
- search.py performs searches and replacements.
- mkheader.py corrects a header file.

The C to C++ program with all the python sources is under the GNU GPL license,
that minds you may use it and distribute it freely, providing the copyright is unchanged.

See at the COPYING file for details. This doesnt mean GNU encourages you to convert your C sources to C++. In fact, most of the tools here included may help C programmers outside C++ conversion.

Installing:

Type:
./configure
./setup
mkdoc ...this will generate an html and info manuals.

Booting Ubuntu To RAM

Booting Ubuntu To RAM


Booting Ubuntu To RAM is an article aims to document the process of creating a customized Ubuntu that loads an image in RAM. more>>
Booting Ubuntu To RAM is an article aims to document the process of creating a customized Ubuntu that loads an image from the hard disk to RAM, then boots an entire Ubuntu session out of RAM. It is intended for intermediate to advanced Ubuntu users who are familiar with the shell, and may have limited experience customizing the livecd (LiveCDCustomization) and shell scripting. We will customize a LiveCD and copy it to the hard drive, and make a few modifications to bootup scripts so that it copies to RAM via our good friend tmpfs.
WARNING: The author asserts that this procedure works for him, but cannot guarantee that this procedure works for anyone else. Although this procedure is meant to be 100% safe, it is feasible that there may be mistakes, or a chance of misunderstanding the instructions in a manner that causes loss of data. Please make a backup and do not attempt on mission critical systems. Read through this article thoroughly, and do not attempt if you do not comprehend or feel comfortable about any of the instructions!
CAUTION: I hope this is intuitively obvious, but Ill humor you and state it bluntly: Changes you make under the live session are NOT saved and WILL BE LOST when you reboot or shut down. Dont save anything important to the "home directory" and expect it to still be around! If you want to save data permanently, mount a permanent medium (such as your hard drive), plug in a thumbdrive, or use some network functionality built into Ubuntu to save your data to a non-volatile destination.
There are many cases where one would like to boot Ubuntu to RAM:
- Performance: The desktop performance is dramatically improved. A 400MB squashed filesystem in RAM, that holds 1200MB of data, is read back on a 1.6GHz Core Duo in about 3 seconds, including decompression time.
- Power, Noise, Durability: Although modern hard disks dont use much power compared to other system components, this may still be important for some. In laptops, hard disks are often the noisiest components, so this setup can reduce system noise. With the hard disk spun down, a laptop can potentially withstand greater shocks without damage.
- Abrupt poweroff: Since the hard disk is only momentarily used in read-only mode during boot, then never touched again, there are few or no negative consequences of an abrupt poweroff. If a system is used where power is inconsistent, or the system is regularly used in a context where fast shutoffs are required, this is very handy.
- Privacy: Anything you do in this session are lost when you reboot or power off. This is great for kiosks or other systems where permanent modification are not desired. (Note that by default the livecd user has full sudo access, so potentially a malicious user can still make permanent changes by mounting the hard drive and following this HOWTO)

IRC to MSN gateway 0.1

IRC to MSN gateway 0.1


This is the IRC gateway for Microsoft(tm) Messenger. more>>
This is the IRC gateway for Microsoft(tm) Messenger.

You probably wonder what this is and why I wrote this. Some more information can be found in the DESIGN document that is included in this package.

This software is written by Johannes Verelst and is licensed through the GPL license (http://www.gnu.org/licenses/gpl.html).

Note that this is pre-alpha code, it probably does a bit that you want, but dont email me bugreports or feature requests. It is under heavy development.

If this program doesnt run try to install corectly all required perl modules yourself.

The idea for this program came when I was getting annoyed by the fact that I had to use different programs for both IRC and MSN. Since I dont know of any good MSN clients that can do IRC too (on unix, ofcourse), I started thinking about the other way around: an IRC client that can do MSN.

When I saw a piece of software written by Adam Swann that allows easy connectivity to MSN with perl, I decided to write an IRC server in perl that would connect to MSN for you. This is the result.

Scriptol to C++ for Linux 5.5

Scriptol to C++ for Linux 5.5


A modern programming language, designed to be simple and easy to learn. more>> Scriptol is a modern programming language, designed to be simple and easy to learn, allowing new users ready to program in some hours. The programming time is largely decreased.
Scriptol is object-oriented, xml-oriented, extensible, universal, uses C++, PHP or Java APIs, and GTK for graphical user interface. It is universal, that means it is convenient for scripting, to build applications or to make dynamic web pages.
Free scriptol interpreter and compilers are currently available for Windows and Unix.
Features of Scriptol
Scriptol is :
objectively modern: it has been designed according to seven rules for simplicity, safety, and doesnt carry ancient obsolete syntax.
object-oriented, even simple scalar as "int", or literal as "123", are objects and have methods.
typed: the compiler can check for content and type of variables, that is not possible with usually untyped scripting languages.
natural: types are not based on computers hardware but on humans concepts or mathematical sets: these are text, number, integer, real, etc...
powerful and safe: new control structures has been introduced with scriptol.
Examples:
- composite if, that is both an if statement and a switch case with any kind of values.
- while let, that protects from infinite loop.
- for .. in array, or for .. in a..b, the simplest way to express ranges.
simple: no symbols as -> or ::, just a dot in any case.
Adding 1 to x is just written: x + 1, and not x += 1.
No memory management required, executables have a garbage collector.
C++ compatible: you have just to link C++ object files or library files, and use the functions they hold, no any extension required to write!
For example, you have just to add the GTK import libraries in the configuration file of a scriptol source to use the GTK user interface...
PHP compatible: you can program web pages in Scriptol, your code is converted to Php and all Php functions may be used.
