Tripoli 0.3.1

Tripoli 0.3.1


Tripoli project is a Python triplespace implementation. more>>
Tripoli project is a Python triplespace implementation.

Tripoli is a Python implementation of a "triple space": that is, a triple store with tuple space semantics. It supports the synchronization of concurrent processes via a shared data structure.

Processes can add triples to the store, and read or take triples from the store using pattern matching.

If a triple matching a pattern is not yet in the store, a query will block until a suitable triple is added by some other process.

Many synchronization patterns can be expressed using these primitives.

Tripoli extends the semantics of tuple spaces with two additional operations, copy_graph and copy_collect_graph.

These copy or move the graph of all triples that are connected to a given subject to a new triple space, and can be used together with the other pattern matching operations to express procedural queries over triple data.

TrueCrypt 4.3a

TrueCrypt 4.3a


TrueCrypt is free open-source disk encryption software. more>>
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.

#!/usr/bin/perl

use strict;
use GD::Simple;

my @color_names = GD::Simple->color_names;
my $cols = int(sqrt(@color_names));
my $rows = int(@color_names/$cols)+1;

my $cell_width = 100;
my $cell_height = 50;
my $legend_height = 16;
my $width = $cols * $cell_width;
my $height = $rows * $cell_height;

my $img = GD::Simple->new($width,$height);
$img->font(gdSmallFont);

for (my $c=0; $cfgcolor($color);
$img->rectangle(@topleft,@botright);
$img->moveTo($topleft[0]+2,$botright[1]+$legend_height-2);
$img->fgcolor(black);
$img->string($color);

RDQLPlus provides a Java RDQL tool, featuring zoomable query results.
It can work with existing RDF files, Jena2 RDF databases, and a native Java database called Mckoi.
Main features:
- INSERT and DELETE statements into/from RDF graphs ("Models")
- CREATE and DROP entire models in RDF storage locations ("Stores")
- DUMP and LOAD models in RDF/XML, N-TRIPLES, and N3 format
- Copy RDF graphs (or sub-graphs) from one model to another
- Query and work with inference models (using one of Jenas reasoners) given an ontology and an instance model
- Output query results in text form
Version restrictions:
- Some filesystem store files arent recognized, even though theyre listed with the STORES command. If youre having this problem, just rename the file to something simpler, like "myfile.rdf".
- After creating and DROPping an inference model, models that it depends on may not be DROPpable until re-starting RDQLPlus. When you try to DROP such a model, you will be told it was succesfully dropped. But listing MODELs will reveal it is still there.
- You absolutely need version 1.10 of GraphViz to run RDQLPlus. Older versions can create unexpected output, which causes ZVTM to throw a NullPointerException at times.
- On-line help via the HELP command doesnt provide much detail yet. The RIDIQL Reference does.

Jikes RVM 2.9.1

Jikes RVM 2.9.1


Jikes RVM is a virtual machine and runtime environment for Java. more>>
Jikes RVM is a compiler that translates JavaTM source files as defined in The Java Language Specification into the bytecoded instruction set and binary format defined in The Java Virtual Machine Specification.

You may wonder why the world needs another Java compiler, considering that Sun provides javac free with its SDK. Jikes has five advantages that make it a valuable contribution to the Java community: [OSI Certified Logo]

* Open source. Jikes is OSI Certified Open Source Software. OSI Certified is a certification mark of the Open Source Initiative.
* Strictly Java compatible. Jikes strives to adhere to both The Java Language Specification and The Java Virtual Machine Specification as tightly as possible, and does not support subsets, supersets, or other variations of the language. The FAQ describes some of the side effects of this strict language conformance.
* High performance. Jikes is a high performance compiler, making it ideal for use with larger projects.
* Dependency analysis. Jikes performs a dependency analysis on your code that provides two very useful features: Incremental builds and makefile generation.
* Constructive Assistance. Jikes strives to help the programmer write better code in two key ways. Jikes has always strived to provide clear error and warning text to assist the programmer in understanding problems, and now with release 1.19 Jikes helps point out common programming mistakes as documented in Effective Java.

Abridged from a FAQ entry which was adapted from some material by Lou Grinzo for an article he wrote.

The fact that Jikes is a high-performance, highly compatible Java compiler that can be used on almost any computing platform makes it an interesting program and worth investigating for almost any Java programmer. But Jikes is also notable because it lies at the center of two events: the adoption of open source philosophy and practice by large corporations, and the continued growth of Java for Linux.

Its worth pointing out that Jikes is not, and is not intended to be, a complete development environment -- it is simply a command line compiler. It should not be considered a replacement for more complete tools, such as Source Navigator or IBMs VisualAge for Java which provide sophisticated graphical IDEs (Integrated Development Environments).

The Jikes compiler was released in binary form in April 1997 on the IBM alphaWorks site. Jikes for Linux was released on 15 July 1998. The response was overwhelming -- Jikes had more downloads in the three months after the announcement than in the fifteen months before the announcement.

Around the end of March 2002, IBM opened a fledgling community hosting location attached to their developerWorks site with Jikes as a founding member. Approximately 3 years later this server was decommissioned and the most active projects migrated into SourceForge.net hosting options. During those three years Jikes was the #1 most popular project every month, often by a large margin. We approached nearly 250,000 downloads while residing at dw/oss, and had been consistently tallying triple digit daily downloads.

Release of Jikes for Linux was soon followed by requests to open up the source. Many notes and comments from users suggested this would be a good idea. The source was released under a liberal license in December 1998 to make a very visible demonstration of IBMs commitment to open standards and to Java Technology, to make Jikes more reliable and accessible, to encourage more widespread use of Java Technology, to encourage standardization of Java Technology, and to gain some experience actually running an open source project. This marked the start of one of IBMs first efforts in the open source arena.

The original alphaWorks version of Jikes was written by Philippe Charles and Dave Shields of the IBM T. J. Watson Research Center. For awhile after the release of the source they continued to work on the compiler as contributors; however, shortly after the project migrated to developerWorks Open Source Server they were officially moved off onto other projects within IBM. Today there are no IBMers who work on Jikes as part of their job description. Jikes survives today soley based on the free time contributions of members of the open source community.

The source code is available under IBMs Public License, which has been approved by the OSI (Open Source Initiative) as a fully certified open source license. The project provides access to the complete CVS development tree, which includes not only Jikes, but also the source for the Jacks Test Suite and the Jikes Parser Generator used to build Jikes. Jikes is included in many Open Source Operating Systems. The Jacks Test Suite is a replacement for the Jikestst package.

Bio::Ontology::Relationship 1.4

Bio::Ontology::Relationship 1.4


Bio::Ontology::Relationship is a relationship for an ontology. more>>
Bio::Ontology::Relationship is a relationship for an ontology.

SYNOPSIS

$rel = Bio::Ontology::Relationship->new( -identifier => "16847",
-subject_term => $subj,
-object_term => $obj,
-predicate_term => $pred );

This is a basic implementation of Bio::Ontology::RelationshipI.

The terminology we use here is the one commonly used for ontologies, namely the triple of (subject, predicate, object), which in addition is scoped in a namespace (ontology). It is called triple because it is a tuple of three ontology terms.

There are other terminologies in use for expressing relationships. For those who it helps to better understand the concept, the triple of (child, relationship type, parent) would be equivalent to the terminology chosen here, disregarding the question whether the notion of parent and child is sensible in the context of the relationship type or not. Especially in the case of ontologies with a wide variety of predicates the parent/child terminology and similar ones can quickly become ambiguous (e.g., A synthesises B), meaningless (e.g., A binds B), or even conflicting (e.g., A is-parent-of B), and are therefore strongly discouraged.

perlhack 5.8.8

perlhack is a Perl module that will show you how to hack at the Perl internals. more>>
perlhack is a Perl module that will show you how to hack at the Perl internals.

This document attempts to explain how Perl development takes place, and ends with some suggestions for people wanting to become bona fide porters.
The perl5-porters mailing list is where the Perl standard distribution is maintained and developed. The list can get anywhere from 10 to 150 messages a day, depending on the heatedness of the debate. Most days there are two or three patches, extensions, features, or bugs being discussed at a time.

A searchable archive of the list is at either:

http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/

or

http://archive.develooper.com/perl5-porters@perl.org/

List subscribers (the porters themselves) come in several flavours. Some are quiet curious lurkers, who rarely pitch in and instead watch the ongoing development to ensure theyre forewarned of new changes or features in Perl. Some are representatives of vendors, who are there to make sure that Perl continues to compile and work on their platforms. Some patch any reported bug that they know how to fix, some are actively patching their pet area (threads, Win32, the regexp engine), while others seem to do nothing but complain. In other words, its your usual mix of technical people.

Over this group of porters presides Larry Wall. He has the final word in what does and does not change in the Perl language. Various releases of Perl are shepherded by a "pumpking", a porter responsible for gathering patches, deciding on a patch-by-patch, feature-by-feature basis what will and will not go into the release. For instance, Gurusamy Sarathy was the pumpking for the 5.6 release of Perl, and Jarkko Hietaniemi was the pumpking for the 5.8 release, and Rafael Garcia-Suarez holds the pumpking crown for the 5.10 release.
In addition, various people are pumpkings for different things. For instance, Andy Dougherty and Jarkko Hietaniemi did a grand job as the Configure pumpkin up till the 5.8 release. For the 5.10 release H.Merijn Brand took over.

Larry sees Perl development along the lines of the US government: theres the Legislature (the porters), the Executive branch (the pumpkings), and the Supreme Court (Larry). The legislature can discuss and submit patches to the executive branch all they like, but the executive branch is free to veto them. Rarely, the Supreme Court will side with the executive branch over the legislature, or the legislature over the executive branch. Mostly, however, the legislature and the executive branch are supposed to get along and work out their differences without impeachment or court cases.

You might sometimes see reference to Rule 1 and Rule 2. Larrys power as Supreme Court is expressed in The Rules:

Larry is always by definition right about how Perl should behave. This means he has final veto power on the core functionality.

Larry is allowed to change his mind about any matter at a later date, regardless of whether he previously invoked Rule 1.

Got that? Larry is always right, even when he was wrong. Its rare to see either Rule exercised, but they are often alluded to.

New features and extensions to the language are contentious, because the criteria used by the pumpkings, Larry, and other porters to decide which features should be implemented and incorporated are not codified in a few small design goals as with some other languages. Instead, the heuristics are flexible and often difficult to fathom. Here is one persons list, roughly in decreasing order of importance, of heuristics that new features have to be weighed against:

Does concept match the general goals of Perl?

These havent been written anywhere in stone, but one approximation is:

1. Keep it fast, simple, and useful.
2. Keep features/concepts as orthogonal as possible.
3. No arbitrary limits (platforms, data sizes, cultures).
4. Keep it open and exciting to use/patch/advocate Perl everywhere.
5. Either assimilate new technologies, or build bridges to them.

Where is the implementation?

All the talk in the world is useless without an implementation. In almost every case, the person or people who argue for a new feature will be expected to be the ones who implement it. Porters capable of coding new features have their own agendas, and are not available to implement your (possibly good) idea.

Backwards compatibility

Its a cardinal sin to break existing Perl programs. New warnings are contentious--some say that a program that emits warnings is not broken, while others say it is. Adding keywords has the potential to break programs, changing the meaning of existing token sequences or functions might break programs.

Could it be a module instead?

Perl 5 has extension mechanisms, modules and XS, specifically to avoid the need to keep changing the Perl interpreter. You can write modules that export functions, you can give those functions prototypes so they can be called like built-in functions, you can even write XS code to mess with the runtime data structures of the Perl interpreter if you want to implement really complicated things. If it can be done in a module instead of in the core, its highly unlikely to be added.

Is the feature generic enough?

Is this something that only the submitter wants added to the language, or would it be broadly useful? Sometimes, instead of adding a feature with a tight focus, the porters might decide to wait until someone implements the more generalized feature. For instance, instead of implementing a "delayed evaluation" feature, the porters are waiting for a macro system that would permit delayed evaluation and much more.

Does it potentially introduce new bugs?

Radical rewrites of large chunks of the Perl interpreter have the potential to introduce new bugs. The smaller and more localized the change, the better.

Does it preclude other desirable features?

A patch is likely to be rejected if it closes off future avenues of development. For instance, a patch that placed a true and final interpretation on prototypes is likely to be rejected because there are still options for the future of prototypes that havent been addressed.

Is the implementation robust?

Good patches (tight code, complete, correct) stand more chance of going in. Sloppy or incorrect patches might be placed on the back burner until the pumpking has time to fix, or might be discarded altogether without further notice.

Is the implementation generic enough to be portable?

The worst patches make use of a system-specific features. Its highly unlikely that nonportable additions to the Perl language will be accepted.

Is the implementation tested?

Patches which change behaviour (fixing bugs or introducing new features) must include regression tests to verify that everything works as expected. Without tests provided by the original author, how can anyone else changing perl in the future be sure that they havent unwittingly broken the behaviour the patch implements? And without tests, how can the patchs author be confident that his/her hard work put into the patch wont be accidentally thrown away by someone in the future?

Is there enough documentation?

Patches without documentation are probably ill-thought out or incomplete. Nothing can be added without documentation, so submitting a patch for the appropriate manpages as well as the source code is always a good idea.

Is there another way to do it?

Larry said "Although the Perl Slogan is Theres More Than One Way to Do It, I hesitate to make 10 ways to do something". This is a tricky heuristic to navigate, though--one mans essential addition is another mans pointless cruft.

Does it create too much work?

Work for the pumpking, work for Perl programmers, work for module authors, ... Perl is supposed to be easy.

Patches speak louder than words

Working code is always preferred to pie-in-the-sky ideas. A patch to add a feature stands a much higher chance of making it to the language than does a random feature request, no matter how fervently argued the request might be. This ties into "Will it be useful?", as the fact that someone took the time to make the patch demonstrates a strong desire for the feature.

If youre on the list, you might hear the word "core" bandied around. It refers to the standard distribution. "Hacking on the core" means youre changing the C source code to the Perl interpreter. "A core module" is one that ships with Perl.
