Free triple triad silver software for linux

Clearlooks-XPSilver is yet another excellent addition for Gnome users. It is actually a theme that aims to replicate Windows XP Silver color scheme, but the final result is a little different.

RDF::Simple::Parser is a simple RDF/XML parser that reads a string containing RDF in XML.

SYNOPSIS

my $uri = http://www.zooleika.org.uk/bio/foaf.rdf;
my $rdf = LWP::Simple::get($uri);

my $parser = RDF::Simple::Parser->new(base => $uri)
my @triples = $parser->parse_rdf($rdf);

# returns an array of array references which are triples

smf-grey is a Sendmail milter that implements the GreyList Anti SPAM technology.
This technology can significantly reduce the amount of SPAM and viruses going from zombie computers (infected Windows PC), which produce more than 80% of SPAM.
GreyList Sendmail milter has a very effective GreyList algorithm on the base of the tuple: sender IP address (C class subnet), sender envelope and recipient envelope.
Its very recommended to use the smf-grey milter combined with the smf-zombie and the smf-spf milters. Its a triple impact on SPAM and viruses, that will seriously increase the efficiency of filtration.
This milter aims to be lightweight, reliable and simple. Its written in C.
Main features:
- It has a hosts/networks whitelist;
- It has an autowhitelist;
- It can add the information header with GreyList results to scanned messages;
- It can log all milter activities through the syslog service.
Advantages:
- Small code;
- Fast work;
- Stability (production quality);
- Few system resources are required.
Enhancements:
- Whitelists auto reloading was implemented.
- Autowhitelisted records regular dumping and reloading was implemented.
- The default greylisting time period was increased.
- New TODO tasks were added.
- Cosmetic enhancements were made.

TrueCrypt is free open-source disk encryption software.
Main features:
- It can create a virtual encrypted disk within a file and mount it as a real disk.
- It can encrypt an entire hard disk partition or a device, such as USB memory stick, floppy disk, etc.
- Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:
- 1) Hidden volume (more information may be found here).
- 2) No TrueCrypt volume can be identified (TrueCrypt volumes cannot be distinguished from random data).
- Encryption algorithms: AES-256, Blowfish (448-bit key), CAST5, Serpent (256-bit key), Triple DES, and Twofish (256-bit key). Supports cascading (e.g., AES-Twofish-Serpent).
- Based on Encryption for the Masses (E4M) 2.02a, which was conceived in 1997.
Enhancements:
- Access rights are now elevated using sudo.
- Volumes can be dismounted only by the user who mounted it or by root.
- Support for writing data to file-hosted volumes located on devices that use a sector size other than 512 bytes (e.g. new HDD types, DVD-RAM, some flash drives) was added.
- A TrueCrypt volume is now automatically dismounted if its host device is inadvertently removed.
- The maximum allowed size of FAT32 volumes was increased to 2 TB.
- Support for big-endian platforms was improved. 64-bit block ciphers are being phased out; such volumes can still be mounted, but not created.

GD::Simple is a subclass of the GD library that shortens many of the long GD method calls by storing information about the pen color, size and position in the GD object itself. It also adds a small number of "turtle graphics" style calls for those who prefer to work in polar coordinates. In addition, the library allows you to use symbolic names for colors, such as "chartreuse", and will manage the colors for you.

The Pen

GD::Simple maintains a "pen" whose settings are used for line- and shape-drawing operations. The pen has the following properties:

fgcolor

The pen foreground color is the color of lines and the borders of filled and unfilled shapes.

bgcolor

The pen background color is the color of the contents of filled shapes.

pensize

The pen size is the width of the pen. Larger sizes draw thicker lines.

position

The pen position is its current position on the canvas in (X,Y) coordinates.

angle

When drawing in turtle mode, the pen angle determines the current direction of lines of relative length.

turn

When drawing in turtle mode, the turn determines the clockwise or counterclockwise angle that the pen will turn before drawing the next line.

font

The font to use when drawing text. Both built-in bitmapped fonts and TrueType fonts are supported.

fontsize

The size of the font to use when drawing with TrueType fonts.

One sets the position and properties of the pen and then draws. As the drawing progresses, the position of the pen is updated.

Methods

GD::Simple introduces a number of new methods, a few of which have the same name as GD::Image methods, and hence change their behavior. In addition to these new methods, GD::Simple objects support all of the GD::Image methods. If you make a method call that isnt directly supported by GD::Simple, it refers the request to the underlying GD::Image object. Hence one can load a JPEG image into GD::Simple and declare it to be TrueColor by using this call, which is effectively inherited from GD::Image:

my $img = GD::Simple->newFromJpeg(./myimage.jpg,1);

The rest of this section describes GD::Simple-specific methods.

$img->moveTo($x,$y)

This call changes the position of the pen without drawing. It moves the pen to position ($x,$y) on the drawing canvas.

$img->move($dx,$dy)
$img->move($dr)

This call changes the position of the pen without drawing. When called with two arguments it moves the pen $dx pixels to the right and $dy pixels downward. When called with one argument it moves the pen $dr pixels along the vector described by the current pen angle.

$img->lineTo($x,$y)

The lineTo() call simultaneously draws and moves the pen. It draws a line from the current pen position to the position defined by ($x,$y) using the current pen size and color. After drawing, the position of the pen is updated to the new position.

$img->line($dx,$dy)
$img->line($dr)

The line() call simultaneously draws and moves the pen. When called with two arguments it draws a line from the current position of the pen to the position $dx pixels to the right and $dy pixels down. When called with one argument, it draws a line $dr pixels long along the angle defined by the current pen angle.

$img->clear

This method clears the canvas by painting over it with the current background color.

$img->rectangle($x1,$y1,$x2,$y2)

This method draws the rectangle defined by corners ($x1,$y1), ($x2,$y2). The rectangles edges are drawn in the foreground color and its contents are filled with the background color. To draw a solid rectangle set bgcolor equal to fgcolor. To draw an unfilled rectangle (transparent inside), set bgcolor to undef.

$img->ellipse($width,$height)

This method draws the ellipse centered at the current location with width $width and height $height. The ellipses border is drawn in the foreground color and its contents are filled with the background color. To draw a solid ellipse set bgcolor equal to fgcolor. To draw an unfilled ellipse (transparent inside), set bgcolor to undef.

$img->arc($cx,$cy,$width,$height,$start,$end [,$style])

This method draws filled and unfilled arcs. See GD for a description of the arguments. To draw a solid arc (such as a pie wedge) set bgcolor equal to fgcolor. To draw an unfilled arc, set bgcolor to undef.

$img->polygon($poly)

This method draws filled and unfilled polygon using the current settings of fgcolor for the polygon border and bgcolor for the polygon fill color. See GD for a description of creating polygons. To draw a solid polygon set bgcolor equal to fgcolor. To draw an unfilled polygon, set bgcolor to undef.

$img->polyline($poly)

This method draws polygons without closing the first and last vertices (similar to GD::Image->unclosedPolygon()). It uses the fgcolor to draw the line.

$img->string($string)

This method draws the indicated string starting at the current position of the pen. The pen is moved to the end of the drawn string. Depending on the font selected with the font() method, this will use either a bitmapped GD font or a TrueType font. The angle of the pen will be consulted when drawing the text. For TrueType fonts, any angle is accepted. For GD bitmapped fonts, the angle can be either 0 (draw horizontal) or -90 (draw upwards).

For consistency between the TrueType and GD font behavior, the string is always drawn so that the current position of the pen corresponds to the bottom left of the first character of the text. This is different from the GD behavior, in which the first character of bitmapped fonts hangs down from the pen point.
This method returns a polygon indicating the bounding box of the rendered text. If an error occurred (such as invalid font specification) it returns undef and an error message in $@.

$metrics = $img->fontMetrics

($metrics,$width,$height) = GD::Simple->fontMetrics($font,$fontsize,$string)

This method returns information about the current font, most commonly a TrueType font. It can be invoked as an instance method (on a previously-created GD::Simple object) or as a class method (on the GD::Simple class).

When called as an instance method, fontMetrics() takes no arguments and returns a single hash reference containing the metrics that describe the currently selected font and size. The hash reference contains the following information:

xheight the base height of the font from the bottom to the top of
a lowercase m

ascent the length of the upper stem of the lowercase d

descent the length of the lower step of the lowercase j

lineheight the distance from the bottom of the j to the top of
the d

leading the distance between two adjacent lines

($delta_x,$delta_y)= $img->stringBounds($string)

This method indicates the X and Y offsets (which may be negative) that will occur when the given string is drawn using the current font, fontsize and angle. When the string is drawn horizontally, it gives the width and height of the strings bounding box.

$delta_x = $img->stringWidth($string)

This method indicates the width of the string given the current font, fontsize and angle. It is the same as ($img->stringBounds($string))[0]

($x,$y) = $img->curPos

Return the current position of the pen. Set the current position using moveTo().

$font = $img->font([$newfont] [,$newsize])

Get or set the current font. Fonts can be GD::Font objects, TrueType font file paths, or fontconfig font patterns like "Times:italic" (see fontconfig). The latter feature requires that you have the fontconfig library installed and are using libgd version 2.0.33 or higher.

As a shortcut, you may pass two arguments to set the font and the fontsize simultaneously. The fontsize is only valid when drawing with TrueType fonts.

$size = $img->fontsize([$newfontsize])

Get or set the current font size. This is only valid for TrueType fonts.

$size = $img->penSize([$newpensize])

Get or set the current pen width for use during line drawing operations.

$angle = $img->angle([$newangle])

Set the current angle for use when calling line() or move() with a single argument.

Here is an example of using turn() and angle() together to draw an octagon. The first line drawn is the downward-slanting top right edge. The last line drawn is the horizontal top of the octagon.

$img->moveTo(200,50);
$img->angle(0);
$img->turn(360/8);
for (1..8) { $img->line(50) }

$angle = $img->turn([$newangle])

Get or set the current angle to turn prior to drawing lines. This value is only used when calling line() or move() with a single argument. The turning angle will be applied to each call to line() or move() just before the actual drawing occurs.
Angles are in degrees. Positive values turn the angle clockwise.

$color = $img->fgcolor([$newcolor])

Get or set the pens foreground color. The current pen color can be set by (1) using an (r,g,b) triple; (2) using a previously-allocated color from the GD palette; or (3) by using a symbolic color name such as "chartreuse." The list of color names can be obtained using color_names().

$color = $img->bgcolor([$newcolor])

Get or set the pens background color. The current pen color can be set by (1) using an (r,g,b) triple; (2) using a previously-allocated color from the GD palette; or (3) by using a symbolic color name such as "chartreuse." The list of color names can be obtained using color_names().

$index = $img->translate_color(@args)

Translates a color into a GD palette or TrueColor index. You may pass either an (r,g,b) triple or a symbolic color name. If you pass a previously-allocated index, the method will return it unchanged.

$index = $img->alphaColor(@args,$alpha)

Creates an alpha color. You may pass either an (r,g,b) triple or a symbolic color name, followed by an integer indicating its opacity. The opacity value ranges from 0 (fully opaque) to 127 (fully transparent).
@names = GD::Simple->color_names

$translate_table = GD::Simple->color_names

Called in a list context, color_names() returns the list of symbolic color names recognized by this module. Called in a scalar context, the method returns a hash reference in which the keys are the color names and the values are array references containing [r,g,b] triples.

$gd = $img->gd

Return the internal GD::Image object. Usually you will not need to call this since all GD methods are automatically referred to this object.

($red,$green,$blue) = GD::Simple->HSVtoRGB($hue,$saturation,$value)

Convert a Hue/Saturation/Value (HSV) color into an RGB triple. The hue, saturation and value are integers from 0 to 255.

($hue,$saturation,$value) = GD::Simple->RGBtoHSV($hue,$saturation,$value)

Convert a Red/Green/Blue (RGB) value into a Hue/Saturation/Value (HSV) triple. The hue, saturation and value are integers from 0 to 255.

COLORS

This script will create an image showing all the symbolic colors.

Sepia is a simple Emacs-Perl Interface.

@compls = completions($string [, $type])

Find a list of completions for $string with glob type $type. Completion operates on word subparts separated by [:_], so e.g. "S:m_w" completes to "Sepia::my_walksymtable".

@locs = location(@names)

Return a list of [file, line, name] triples, one for each function name in @names.

@matches = apropos($name [, $is_regex])

Search for function $name, either in all packages or, if $name is qualified, only in one package. If $is_regex is true, the non-package part of $name is a regular expression.

@names = mod_subs($pack)

Find subs in package $pack.

@decls = mod_decls($pack)

Generate a list of declarations for all subroutines in package $pack.

$info = module_info($module, $type)

Emacs-called function to get module information.

$file = mod_file($mod)

Find the likely file owner for module $mod.

@mods = package_list

Gather a list of all distributions on the system. XXX UNUSED

@mods = module_list

Gather a list of all packages (.pm files, really) installed on the system, grouped by distribution. XXX UNUSED

@mods = doc_list

Gather a list of all documented packages (.?pm files, really) installed on the system, grouped by distribution. XXX UNUSED

lexicals($subname)

Return a list of $subnames lexical variables. Note that this includes all nested scopes -- I dont know if or how Perl distinguishes inner blocks.

$lisp = tolisp($perl)

Convert a Perl scalar to some ELisp equivalent.

printer(@res [, $iseval])

Print @res appropriately on the current filehandle. If $iseval is true, use terse format. Otherwise, use human-readable format.

repl(*FH)

Execute a command interpreter on FH. The prompt has a few bells and whistles, including:

* Obviously-incomplete lines are treated as multiline input.

* C< die > is overridden to enter a recursive interpreter at the point
C< die > is called. From within this interpreter, you can examine a
backtrace by calling "bt", return from C< die > with "r EXPR", or
go ahead and die by pressing Control-c.

Behavior is controlled in part through the following package-globals:

$PS1 -- the default prompt

$STOPDIE -- true to enter the inspector on die()

$STOPWARN -- true to enter the inspector on warn()

%REPL -- maps shortcut names to handlers

$PACKAGE -- evaluation package

$WANTARRAY -- evaluation context

$PRINTER -- result printer (default: print_dumper)
