Explode function to divide string

This will show explode function .
it will divide the string into number of chunks


$someWords = "Please don't blow me to pieces.";

$wordChunks = explode(" ", $someWords);
for($i = 0; $i < count($wordChunks); $i++){  echo "Piece $i = $wordChunks[$i]
";
}

$wordChunksLimited = explode(" ", $someWords, 4);
for($i = 0; $i < count($wordChunksLimited); $i++){  echo "Limited Piece $i = $wordChunksLimited[$i]
";
}

File copy from one directory in Perl

It will copy file from one directory to other directory

it will copy file from its current directory to HTML directory


#!/usr/bin/perl
use File::Copy;

print "content-type: text/html \n\n"; #The header
$filetobecopied = "myhtml.html.";
$newfile = "html/myhtml.html.";
copy($filetobecopied, $newfile) or die "File cannot be copied.";

fetch data using Select query in perl

Here is code to fetch the data from database and display it with loop

#!/usr/bin/perl

use Mysql;

print "Content-type: text/html \n\n";

# MYSQL CONFIG VARIABLES
$host = "localhost";
$database = "store";
$tablename = "inventory";
$user = "username";
$pw = "password";

# PERL MYSQL CONNECT()
$connect = Mysql->connect($host, $database, $user, $pw);

# SELECT DB
$connect->selectdb($database);

# DEFINE A MySQL QUERY
$myquery = "SELECT * FROM $tablename";

# EXECUTE THE QUERY FUNCTION
$execute = $connect->query($myquery);

# HTML TABLE
print "


";

# FETCHROW ARRAY

while (@results = $execute->fetchrow()) {
 print "";
}

print "

product
quantity
"
 .$results[0]."
"
 .$results[1]."
"
 .$results[2]."
";

White Paper

Application DoS attacks exploit flaws in the bespoke application design and implementation to
prevent legitimate access to the victim’s services. They represent a subset of potential attacks
on such applications, as they are aimed specifically at disrupting operation rather than
subverting the application controls.
Attacks based on exploiting these flaws can offer the attacker a number of advantages over
traditional DoS attacks:
• The attacks will typically not be detectable or preventable by existing security
monitoring solutions1 – Since the attacks do not consume an unreasonable amount of
bandwidth and could, in many cases, be indistinguishable from normal traffic.
• Application attacks are more efficient – The attacker may not need as much resource at
their disposal to successfully complete the attack. Application level attacks target
bottlenecks and resources limitations within the application and do not require many
compromised “zombie” systems or a large amount of bandwidth. Furthermore, they
can be targeted at the weakest link in an environment – for example if a web-farm of a
hundred servers relies on a single back-office host to authenticate users, an application
attack may be able to directly target it.
• Application attacks are harder to trace – Application level attacks normally use HTTP or
HTTPS as their transport. Proxy servers can therefore be used to obfuscate the true
origin of the attacker; and many are available for an attacker to redirect his malicious
traffic. Many of these proxy servers do not keep logs of connection attempts and could
therefore successfully hide the true origin of the attacking host.

Quantum Teleportation

Teleportation is the name given by science fiction writers to the feat of making an object or person disintegrate in one place while a perfect replica appears somewhere else. How this is accomplished is usually not explained in detail, but the general idea seems to be that the original object is scanned in such a way as to extract all the information from it, then this information is transmitted to the receiving location and used to construct the replica, not necessarily from the actual material of the original, but perhaps from atoms of the same kinds, arranged in exactly the same pattern as the original. A teleportation machine would be like a fax machine, except that it would work on 3-dimensional objects as well as documents, it would produce an exact copy rather than an approximate facsimile, and it would destroy the original in the process of scanning it. A few science fiction writers consider teleporters that preserve the original, and the plot gets complicated when the original and teleported versions of the same person meet; but the more common kind of teleporter destroys the original, functioning as a super transportation device, not as a perfect replicator of souls and bodies.

Medical Text Analysis System - Natural Language Processing

The Medical Text Analysis System (MedTAS) is a UIMA-based, modular and flexible system that uses advanced Natural Language Processing (NLP) techniques to extract structured information from unstructured data sources, such as pathology reports, clinical notes, discharge summaries, and medical literature. MedTAS is also a development platform that is adaptable to customer and domain requirements. It has been designed to operate within institutional systems, and seamlessly integrates with IBM products, such as the DB2 Data warehouse.

Implementations of MedTAS have been developed for major medical institutions. MedTAS/P is a version customized for the pathology domain. It is based on a novel representation of cancer, its characteristics and disease progression.

SwiftFile - Artificial Intelligence

SwiftFile for Notes is an intelligent assistant for Lotus Notes that helps users organize their e-mail into folders. SwiftFile uses a text classifier to learn each user's mail-filing habits. SwiftFile uses the model it learns to predict the three folders in which the user is most likely to place each incoming message. The predictions are presented to the user as three shortcut buttons that allow the user to quickly file each message into one of the predicted folders. When one of SwiftFile's predictions is correct, the effort required to file a message is reduced to a single button click. An incremental classifier is used to allow SwiftFile to continuously update its model of the user.

We have performed a number of static and dynamic experiments with SwiftFile as well as some initial user studies. The results show that the shortcut buttons provided by SwiftFile are useful between 80% to 90% of the time, and this performance level is maintained over time despite the constantly-changing classification problem. We also find that the bootstrap period for the classifier is extremely short and that SwiftFile is useful from the moment it is first installed.

Important PHP Website

PHP.net: A Tourist's Guide

Everyone knows the www.php.net site. All of us went there sooner or later, and will keep going back there. This is the central reference point for PHP users, and there is a wealth of information there. Not all of it is obvious. Come with me, I'll show you.

www.php.net: Main Website

This is the primary web site. The front page is where major news is published: new PHP versions, security updates, and new projects launched. This site is also mirrored in dozens of countries worldwide.

This is the home of the download page, for everyone to get the latest version of the PHP source code and binaries for Windows. The current and next-to-current versions are available there. (There is also a PHP Museum, which has all of the source distributions since June 1996.)

The next most visited section is the documentation. The documentation is translated into twelve different languages, and is available in a variety of different formats. Users are able to read notes on the documentation left by other users, and contribute their own notes. The documentation is a real community project by itself!

The support page has all the directions to a wealth of resources both inside and outside of PHP.net. The community has built a huge network of knowledge bases, PHP user groups, and training sessions where anyone can have his or her questions answered. Non-English-speaking users also get a large share of attention.

Now, buckle up your seat belt, and stop smoking. Here are the no-light streets:

talks.php.net: Conference Materials

This is where speakers at various PHP-related conferences keep their slides. It covers all sorts of topics, from the famous 'Rasmus' introduction to PHP to the latest 'PHP system administration', through PEAR and advanced topics. All those slides are available within the PHP slide application.

news.php.net: Mailing Lists Web and NNTP Interface

news.php.net is the web interface to the PHP mailing lists. If you're not subscribed to the mailing lists, but you still want to keep in touch regularly, this is your place. An infinite pile of fresh news and trends of PHP. You can also point your news reader at the NNTP server at news.php.net to follow the lists.

pear.php.net: The PHP Extension and Application Repository

PEAR is the next revolution in PHP. This repository is bringing higher level programming to PHP. PEAR is a framework and distribution system for reusable PHP components. It eases installation by bringing an automated wizard, and packing the strength and experience of PHP users into a nicely organised OOP library.

pecl.php.net: The PHP Extension Community Library

PECL is a repository for PHP Extensions, providing a directory of all known extensions and hosting facilities for downloading and development of PHP extensions.
The packaging and distribution system used by PECL is shared with its sister, PEAR.

bugs.php.net: Bug Database

The bug database is where you can bring problems with PHP to the attention of developers (but don't forget to double-check that somebody else hasn't already reported the same problem!).

doc.php.net: Documentation collaboration

The documentation projects website tries to gather all PHP.net hosted documentation teams together with tools, status reports and an RFC system.

docs.php.net: Documentation dev server

The documentation developmental server is a PHP mirror that contains upcoming releases of the PHP documentation before it's pushed out to the mirrors. Documentation changes, such as layout, is tested here (with feedback requested) before being made official. Documentation is built here four times a day.

qa.php.net: Quality Assurance Team

The Quality Assurance team is one of the most important pieces of the PHP project, protecting users from bugs. It is gathered around the QA mailing list, and this site allows anyone to provide tests and experience to the release process.

cvs.php.net: CVS Repository

The PHP project is organized with a CVS server, and this website is the web interface to it. There you can browse the history (and latest versions) of the source code for all of the PHP projects. For example, the php-src module is the repository for the source code to the latest version of PHP itself.

lxr.php.net: Cross Reference

Cross reference for source code, based on the "Linux Cross Reference". This is the ultimate tool for exploring PHP code. Any time an important macro or function is detected within the code, it is linked to its definition, and all its usage locations. This will help you build your code, and understand the PHP source.

gtk.php.net: PHP-GTK

This web site is the home of the PHP-GTK project, which allows PHP to be used to build graphical interfaces, with slick interface and highly interactive content. You'll find the downloads and docs here, and the latest news from the project.

snaps.php.net: Daily PHP Snapshots

This is your first stop if you're looking for cutting edge development versions of PHP which are generated every day from the current stable and current development sources.

gcov.php.net: Test and Code Coverage analysis

This site is dedicated to automatic PHP code coverage testing. On a regular basis current CVS snapshots are being build and tested on this machine. After all tests are done the results are visualized along with a code coverage analysis.

wiki.php.net: The PHP Wiki

Home of the official PHP wiki, this site contains information related to php.net like RFCs, GSOC information, and TODO files. Most every aspect of the PHP project has a wiki section and everyone is able to apply for wiki commit access.
