How to make a Link to Another Page

Making links is VERY easy. Here is the command:

For example, to make a link on your page to here it would look like this:


This will make a link but you won't be able to see it or use it, to make it work you have to put some text in between the command and the command. You have to include the tag at the end of every link or the rest of your page will be the link!
How to make a link to another page in the same directory

Making a link to a page in the same directory as your intitial page is VERY VERY easy. Here is the script to do it.




For Example, here is how I made a link from this page to the page that shows you colors:


How to make an Image on your Pag

OK, this is also an extremely simple command. It's basically a link but a little different. Here is the script:





How to make Images Into Links

Making images into Links is as easy as combining the two commands:



You have to make sure that the actual Link reference comes before the image. Also the link closing tag has to come last.

How to control the size of your Images

To do this all you have to do is add this into your image command:
width=whatever height=whatever
For example, here it is all together:




How to make text appear beside an image

Have you ever noticed that when you type beside an image the text only starts at the bottom of the pic and you end up with a big empty space? Well, this little addition to the image command will solve that problem:

align=right or align=left
For example, here it is all together:



You don't need to have the height and width in there. This command will do this:
Hey.. this text is at the top and not the bottom. How convenient eh?

How to make "freestyle" text

Making "freestyle"(in other words, text "as is") text is as easy as making it bold or italic. Here is the script:

Here you put your writing.

This way you can do whatever you want, write song lyrics without them turning into a paragraph, write words in list form, etc.

How to make a link that opens a new browser Window

This is as easy as adding a command at the end of the link command. Here is the command:

target=body
For example, here it is all together:



This will open a new window when you make a link, especially useful when making links in chats.

JAVA

The J2ME architecture is based on families and categories of devices. A category defines a particular kind of device; cellular telephones, simple pagers, and organizers are separate categories. A family of devices is made up a of a group of categories that have similar requirements for memory and processing power. Together, cellular phones, simple pagers, and simple personal organizers make up a single family of small-footprint devices.

Figure 1 defines the relationship between the famFigure 1. Families and categories of devices
Families and categories of devices

In order to support the kind of flexibility and customizable deployment demanded by the family of resource-constrained devices, the J2ME architecture is designed to be modular and scalable. This modularity and scalability is defined by J2ME technology in a complete application runtime model, with four layers of software built upon the host operating system of the device.

Figure 2 shows the J2ME architecture.

Figure 2. The J2ME architecture
The J2ME archtiecture

* Java Virtual Machine layer: This layer is an implementation of a Java Virtual Machine that is customized for a particular device's host operating system and supports a particular J2ME configuration.
* Configuration layer: The configuration layer defines the minimum set of Java Virtual Machine features and Java class libraries available on a particular category of devices. In a way, a configuration defines the commonality of the Java platform features and libraries that developers can assume to be available on all devices belonging to a particular category. This layer is less visible to users, but is very important to profile implementers.
* Profile layer: The profile layer defines the minimum set of application programming interfaces (APIs) available on a particular family of devices. Profiles are implemented upon a particular configuration. Applications are written for a particular profile and are thus portable to any device that supports that profile. A device can support multiple profiles. This is the layer that is most visible to users and application providers.
* MIDP layer: The Mobile Information Device Profile (MIDP) is a set of Java APIs that addresses issues such as user interface, persistence storage, and networking.

The Java Virtual Machine layer, configuration layer, and profile layer together constitute the Connected Limited Device Configuration (CLDC). The MID Profile and CLDC provide a standard runtime environment that allows new applications and services to be dynamically deployed on end-user devices.

Programming J2ME with MIDP APIs: The building blocks

The combination of CLDC and MIDP provides a complete environment for creating applications on cell phones and simple two-way pagers.

The core of a MID Profile is a MIDlet application. The application extends the MIDlet class to allow the application management software to control the MIDlet, retrieve properties from the application descriptor, and notify and request state changes.

All MIDlets extend the MIDlet class -- the interface between the runtime environment (the application manager) and the MIDlet application code. The MIDlet class provides APIs for invoking, pausing, restarting, and terminating the MIDlet application.

The application management software can manage the activities of multiple MIDlets within a runtime environment. In addition, the MIDlet can initiate some state changes by itself, and notify the application management software of those changes.

The whole set of MIDP API classes can be broken down into two categories:

* MIDP APIs for the user interface: These APIs are designed so that interaction with the user is based around a succession of screens, each of which presents a reasonable amount of data to the user. Commands are presented to the user on a per-screen basis. The APIs allow the application to determine what screen to display next, what computation to perform, and what request to make of a network service.
* MIDP APIs for handling the database: These APIs organize and manipulate the devices database, which comprises information that remains persistent across multiple invocations of the MIDlet.

The underlying CLDC API is used to handle strings, objects, and integers. A subset of the Java 2 API is also provided to handle I/O and network communications.

Figure 3 shows the building blocks of J2ME.

Figure 3. The building blocks of J2ME
The building blocks of J2ME

The relationship between the standard and micro edition Java APIs is shown in Figure 4.

Figure 4. The relationship between the J2ME and J2SE APIs
The relationship between the J2ME and J2SE APIs

Event handling in J2ME

Event handling in J2ME, in contrast to event handling on the desktop version of the Java platform, is based around a succession of screens. Each screen carries a certain small amount of data.

Commands are presented to the user on a per-screen basis. The Command object encapsulates the name and information related to the semantics of an action. It is primarily used for presenting a choice of actions to the user. The resulting command behavior is defined in a CommandListener associated with the screen.

Each Command contains three pieces of information: a label, a type, and a priority. The label is used for the visual representation of the command; the type and priority are used by the system to determine how the Command is mapped onto a concrete user interface.

Figure 5 shows the event handling mechanism in J2ME.

Figure 5. Handling user events in J2ME
Handling user events in J2ME

Designing the user interfaces

Although it maintains a constrained profile, the MIDP API provides a complete set of UI elements. The following are some of the most important ones:

* An Alert acts as a screen to provide information to the user about an exceptional condition or error.
* A Choice implements a selection from a predefined number of choices.
* A ChoiceGroup provides a group of related choices.
* A Form acts as a container for the other UI elements.
* A List provides a list of choices.
* A StringItem acts as a display-only string.
* A TextBox is a screen that allows the user to enter and edit text.
* A TextField allows the user to enter and edit text. Multiple TextFields can be placed in a Form.
* A DateField is an editable component for presenting date and time information. A DateField can be placed in a Form.
* A Ticker acts as a scrollable display of text.

A complete list of UI elements is available in the MID Profile API documentation that accompanies the J2ME Wireless Toolkit (see Resources below for more information).

Managing the device database

The MIDP provides a set of classes and interfaces to organize and manipulate a device's database: RecordStore, RecordComparator, and RecordFilter. A RecordStore consists of a collection of records, which remain persistent across multiple invocations of the MIDlet. Comparing records in a RecordStore or extracting sets of records from a RecordStore is functionality provided by RecordComparator and RecordFilter interfaces.

Developing J2ME applications

The previous sections have given an overview of J2ME. In this section, we will acquaint ourselves with the practical details of the platform through development of a real-world application on a phone interface.

A sample application: Phone calendar

One of the notable features in J2ME is its date manipulation functionality in a constrained environment. The DateField UI Item offered by J2ME is an editable component for presenting calender information (i.e., date and time). In this section, we will develop a J2ME application that displays a scrolling calendar on a cell phone UI, using DateField and Date functions.

A phone calendar application



// Import of API classes
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import java.util.*;

//A first MIDlet with simple text and a few commands.
public class PhoneCalendar extends MIDlet
implements CommandListener, ItemStateListener {

//The commands
private Command exitCommand;

//The display for this MIDlet
private Display display;

// Display items e.g Form and DateField
Form displayForm;
DateField date;

public PhoneCalendar() {
display = Display.getDisplay(this);
exitCommand = new Command("Exit", Command.SCREEN, 1);
date = new DateField("Select to date", DateField.DATE);

}

// Start the MIDlet by creating the Form and
// associating the exit command and listener.
public void startApp() {
displayForm = new Form("Quick Calendar");
displayForm.append(date);
displayForm.addCommand(exitCommand);
displayForm.setCommandListener(this);
displayForm.setItemStateListener(this);
display.setCurrent(displayForm);
}

public void itemStateChanged(Item item)
{
// Get the values from changed item
}

// Pause is a no-op when there is no background
// activities or record stores to be closed.
public void pauseApp() { }

// Destroy must cleanup everything not handled
// by the garbage collector.
public void destroyApp (boolean unconditional) { }

// Respond to commands. Here we are only implementing
// the exit command. In the exit command, cleanup and
// notify that the MIDlet has been destroyed.
public void commandAction (
Command c, Displayable s) {
if (c == exitCommand) {
destroyApp(false);
notifyDestroyed();
}
}


}


The PhoneCalendar MIDlet as defined above extends an ItemListener and a CommandListener. It gives the MIDlet the capability of tracking an item change on the screen and responding to user commands. The user interface initiative by this application begins by defining a display for the phone screen and attaching a Form to it. The Form acts as a container and can hold a number of user interface items. The commandAction() function acts a command handler in J2ME and defines the actions to be taken for a certain command.

Deploying J2ME

You can download an emulator from Sun that allows you to test J2ME applications on your desktop system. If you'd rather shun all that graphical overhead, you can also deploy J2ME on your command line.

Deploying in an emulated environment

Deploying and running a J2ME application in an emulated environment involves the installation and configuration of an emulator. The J2ME Wireless Toolkit provides an emulated environment for development and deployment of Java applications on top of resource-constrained devices. Here's how to get yourself up and running:

1. Install the J2ME Wireless Toolkit (see Resources). The installer program will guide you with necessary instructions. Choose a standalone mode for running these examples. Choose an integrated mode in case you want to integrate it with an IDE.
2. Create a new project through the user interface of KToolbar. Indicate a class name.
3. Place the class name from Step 2 in the C:\[J2ME Installation directory]\apps\[Project Name]\src directory.
4. Build the project.
5. Choose DefaultGrayPhone as a default device from J2ME Wireless Toolkit -> Default Device Selection.
6. Run the project.

The toolkit also provides an option to package the project into a jar file and a jad file. A double-click on the jad file will deploy the application indicated by the jar file.

Deploying on the command line

A number of command-line options are also available.

1. Create the classfile:

C:\J2ME\apps\PhoneCalendar>
javac _ tmpclasses _ootclasspath
C:\J2ME\lib\midpapi.zip -classpath tmpclasses;
classes src\*.java


2. Create a manifest file, manifest.mf:

MIDlet-1: PhoneCalendar,
PhoneCalendar.png,
PhoneCalendar
MIDlet-Name: Phone Calendar
MIDlet-Vendor: Sun Microsystems
MIDlet-Version: 1.0
MicroEdition-Configuration: CLDC-1.0
MicroEdition-Profile: MIDP-1.0


3. Create a jar file:

C:\J2ME\apps\PhoneCalendar>jar cfm .\bin\
PhoneCalendar.jar
manifest.mf -C classes . _ res .


4. Create a jad file:

MIDlet-1: PhoneCalendar,
PhoneCalendar.png,
PhoneCalendar
MIDlet-Jar-Size: 4490
MIDlet-Jar-URL:
F:\J2ME\apps\PhoneCalendar\bin\
PhoneCalendar.jar
MIDlet-Name: PhoneCalendar
MIDlet-Vendor: Sun Microsystems
MIDlet-Version: 1.0


5. Run the jad file:

C:\J2ME\bin> emulator -Xdescriptor:
C:\J2ME\apps\PhoneCalendar
\bin\PhoneCalendar.jad

wireles boardband MAC LINGSIS WRT

maff klo seandainya mengganggu pola pikir anda, soalnya belajarnya asal-asalan , kita mau belajar cara seting hardware ,yang bervungsi untuk mentransmisikan data secara nirkabel,untuk contoh kasusnya penulis menggunakan radio WRT lingsys , fabrikan dari cisco router,kebanyakan orang sering menggunakan radio ini sebagai periveral di rungan kerjanya ,untuk itu kita mulai aja sekarang ...teknik seting awall..
1. Buka kotaknya, terdapat Router broadband, CD, Adapter, Kabel.
2. Dibagian belakang terlihat terdapat beberapa konektor RJ 45, adapun fungsinya adalah ;
1. Konektor RJ 45 dari ISP
2. Terdapat konektor 1-4,ini dikoneksikan ke PC-PC / ke Switch
3. Ke Adapter Listrik
3. Koneksikan kabel Adapter ke lubang koneksi power lalu hubungkan ke listrik
4. Untuk mengkonfigurasinya, maka yang kita persiapkan adalah ;
1. Tancapkan kabel warna biru yang disertakan didalam kotak ke port di belakang
router dan tancapkan ujung kabel ke Ethernet (port RJ45) di laptop / PC.
2. Set IP PC / Laptop dengan cara,
3. Klik dua kali icon network connection / masuk ke control panel, klik network
connection, klik Local area connection, lalu pilih TCP/IP, lalu klik properties
4. masukan IP diatas, lalu tekan OK
5. Setelah IP address di laptop / PC kita diganti seperti langkah sebelumnya Buka Browser,
ketikan 192.168.1.1 maka akan muncul seperti dibawah ini

Masukan usernya : admin & passwordnya : admin
6. akan muncul, maka settinglah

1. pilih Static IP
2. Masukan IP ADDRESS yang didapat dari ISP nya….
3. Router name : ini nama alat router ini yang akan dibaca oleh PC Client, buat
namanya terserah kita
4. Local IP Address : pilih default aja 192. 168.1 .1 subnet 255. 255.255.0, pilih
DHCP, Starting IP Address buat aja : 192.168.1.100., maximum number DHCP
user : tergantung dari berapa jumlah komputer yang akan terkoneksi, misalnya
ada 8 PC berarti isi dikolom ini 8
5. Tekan save setting
7. Agar supaya hanya PC/ Notebook aja yang terdaftar di router ini dan tidak semua notebook
dapat terkoneksi ke internet, maka aturlah system keamanan wirelessnya, lakukan…klik
tab wireless, maka akan muncul

Lalu pilih Wireless WIRELESS MAC FILTER…

1. Pilih ENABLE, lalu pilih PERMIT ONLY PCs Listed to access the wireless network
2. Klik Edit MAC Filter list, maka akan muncul

3. di kolom MAC 01 sampai dengan 40 adalah nomer MAC address WIRELESS setiap
laptop yang kita daftarkan ke router ini, jika MAC laptop tersebut kita tidak
masukan maka laptop tersebut tidak dapat terkoneksi ke Internet.
4. bagaimana kita tahu alamat MAC address setiap laptop yang akan kita masukan ke
kolom MAC address ini, maka pada laptop yang akan terkoneksi kita lakukan
a. klik START | RUN | ketik cmd
b. ketikan IPCONFIG /ALL
c. maka akan muncul, seperti gambar dibawah ini. Maka perhatikan
• pada Ethernet adapter wireless network connection,
perhatikan physical addressnya, misalnya : 00-15-00-4F-48-E3

5. Lakukan langkah ke 4 untuk laptop yang lain juga.
6. Setelah mendapatkan alamat MAC nya masukan alamat tadi pada kolom MAC Router
seperti pada langkah 2 tadi.

7. Klik save setting untuk simpan,
8. perhatikan pada saat menyalin nomer MAC laptop ke MAC di router menggunakan :
bukan –
8. Nah setelah dilakukan langkah ke 6 sebelumnya, maka cobalah di laptop yang telah
didaftarkan tadi dengan mengetikan PING 192.168.1, seperti dibawah ini .

Selamat berarti kita telah berhasil mengkoneksikan laptop kita dengan menggunakan wireless
9. Biar bisa dikontrol dari jarak jauh (remote network) maka kita harus melakukan konfigurasi
di Administration

1. Password : masukan password anda dan Re-enter to confirm : masukan password
lagi
2. Access Server centang HTTP dan managemen port : 8080
3. klik save setting, jadi nanti kita bisa akses dari jarak jauh (dari Internet) router kita
dengan mengetikan di browser ip address dari ISP:8080, misalnya :
202.93.35.5:8080
10. Selamat Mencoba…

UBUNTU & TEKAT 2008

Aku jadi bingung , entah bagaimna cara belajar yang baik,emmm...akua mau belajar tentang ubuntu dari nol dimulai dari detik ini , karena akibat perubahan yang sangat derastis di bidang informatika , kita ditantang untukbisa mengikuti zaman yang kita alami sekarang ini, untuk itu kita mulai aja sekarang ya, ngak usah ditunda2 lagi..kata pepatah"gunakan waktu luangmu sebelum sempitmu"yakan, aku baru sadar 100% untuk ini, Oleh karena itu ,dihari ju'mat ini akan kujadikan sesuatu yang sangat sepesially for my live , ini adalah suatu tujuan yang sangat mulia,Untuk men jalani hari-hari yang akan mendatang diwaktu esok,kesimpulannya kita harus melangkah demilangkah untuk menuju sesuatu yang kita cita-dan cintakan,STARTING NOW JUMAT JAM SEMBILAN MALAM 28 mei 2008,(FREEDAY AT NINE PM) ADALAH sejarah dirisaya yang saat ini mengalami revolusi secara cepat, sehingga sempat banyak menghabiskan bayanyak pengorbanan,exsample :sepirit,moral,kepribadian, live stile,emm...semuanya deh pokonya semua yang ada di diri saya KELIHATANNNYA SUDAH MENGALAMI REORGANISASI SECARA INTERNAL ,emm..aku hampir terjebak dalam suatu perangkap yang amat sangat mengerikan,,,,alllhamduliilah , segala puji bagi Alloh & Rosulnya , yang telah mengingatkan kami pada jalan yang benar.....aminn,,,,yuk kita mualia aja sekarang untuk ini ,,,UBUNTU & PENGINSTALANNYA DENGAN KONDISI DUAL BOOT... Disini akan di jelaskan secara step by step cara menginstall Ubuntu Edgy. Sebagai catatan harddisk yang digunakan adalah 10Gb (belum di partisi) memory 256MB, Prosesor Intel P4 2.4GHz dan proses penginstallasian ini menggunakan VMware Workstation

Sebelum meng-install Ubuntu pada BIOS harus di set Boot Device Priority-nya dulu, dalam menginstall Ubuntu Boot Device Priority harus di arahkan ke CDROM. Untuk masuk ke BIOS tiap Motherboard mempunyai standart sendiri. Namun sebagian besar tinggal menekan tombol delete atau F2. Ketika membooting pertama kali tekan F2 atau del untuk masuk BIOS, anda harus menekan nya dengan cepat, sebab bila tidak komputer akan masuk ke OS di hardisk. Apabila anda “lebih cepat” dari loading komputer anda maka tampilanya akan muncul sebagai berikut:

1

Kemudian simpan konfigurasinya dan Kemudian reboot ulang



2

a. Mulai meng-install

Setelah di restart, maka akan muncul tampilan layar sebagai berikut (apabila komputer di booting via cdrom)

1

Pilih Start or Install Ubuntu, tunggu hingga muncul layar seperti di bawah

4

Gambar diatas menunjukkan bahwasanya kita telah berhasil menjalankan Ubuntu Live-CD. Di LiveCd kita dapat menjajal kemampuan Ubuntu tanpa harus menginstall ke harddisk, pada saat ini anda dapat menulis dokumen, berinternetan, layaknya anada sudah menginstall ke Harddisk. Dan perlu diingat bahwasanya ini hanya bersifat readonly yang berarti semua dokumen yang di simpan di /home hanya lah sementara dan akan hilang jika di reboot. Kita asumsikan anda mempunyai hardisk baru 10 GB belum di partisi dan akan di install Ubuntu.

Langkah selanjutnya kita harus mempartisi harddisk dulu, klik System>Administration>Gnome Partition Editor

5

Hingga muncul tampilan sebagai berikut

6

Karena kita akan membuat partisi baru maka klik kanan di area hitam muda hingga muncul seperti gambar diatas

7

Kilk create, kemudian tunggu

8

Kilk kanan di area hitam muda lagi hingga muncul gambar diatas. Dan jangan lupa kita harus menentukan berapa mesar partisi yang digunakan. Di sini saya mempunyai harddisk 10 GB dengan di partisi 2 yaitu 8,7 GB untuk ext3 dan sisanya untuk swap. Kilk add bila kita sudah mengkonfigurasinya

9

Setelah kita mengeklik add maka akan muncul warna biru pada areal hitam muda, pada gambar di atas masih terdapat area hitam muda hal ini di karenakan masih adanya ruang sisa. Untuk itu maka kilk kanan lagi pilh new

10

Pada gambar diatas areal yang kosong tadi akan digunakan sebagi partisi swap, kemudian klik add, (linux minimal membutuhkan partisi swap dan root) setelah itu bila kita ingin melakukan tindakan pemartisi hardisk yang telah di lakukan tadi maka klik apply hingga muncul tampilan sebagai berikut

11

Kilk aplly lagi, kmudian tunggu loadingnya

12

Setelah proses pemartisian harddisk selesai maka akam muncul tampilan sebagai berikut

3

Kemudian Klik close. Untuk langsung menginstallnya kita dapat mengeklik icon INSTALL di Desktop dan tunggu loadingnya hingga muncul tampilan sebagai berikut

13

Dalam gambar di atas kita disuruh untuk menentukan bahasa yang akan kita gunakan, dalam gambar di atas saya memilih bahasa Inggris sebagai Bahasa yang akan digunakan, namun bila menghendaki bahasa Indonesia bisa memilih Bahasa Indonesia. Kemudian klik Fordward hingga muncul gambar sebagai berikut

14

Di sini kita akan menunjukkan di mana kita berada, karena dengan menunjukkan dimana kita berada system Ubuntu akan menyetel Format waktu GMT di sini saya menggunakan jakarta, bila sudah selesai kilk fordward

4

Pada gambar di atas kita di susruh untuk menentukan Jenis Keyboard yang kita gunakan, di Indonesia kebanyakan menggunakan American English, klik Fordward hingga muncul gambar sebagai berikut

16

Tampilan in di maksudkan untuk mengisikan identitas kita perlu di ingat saat mengisi username huruf yang digunakan harus kecil semua dan tidak boleh ada spasi, hal yang sama saat kita mengisi nama komputer kita. Klik Fordward hingga muncul gambar sebagai berikut

17

Dari tampilan di atas ada dua pilihan yaitu erase disk dan manually edit. Yang dimaksud dengan erase disk adalah menghapus semua isi dari hard disk namun ini cukup berbahaya apa bila anda mempunyai data yang sudah di simpan di harddisk. Untuk amanya pilih manually edit partition. Klik Fordward hingga muncul gambar sebagai berikut

18

Karena kita tadi sudah membuat partisi maka Klik Fordward hingga muncul gambar sebagai berikut

19

Dari gambar di atas kita disuruh untuk menentukan mount point dari dua partisi yang telah kita buat tadi, buatlah seperti gambar di atas. Klik Fordward hingga muncul gambar sebagai berikut

20

Ini adalah konfigurasi global yang telah kita buat untuk menginstall, Klik install (bila kita sudah mantap dengan konfigurasinya) hingga muncul gambar sebagai berikut

21

Bila komputer anda menunjukkan gambar seperti ini, maka Ubuntu sedang menyalin system ke dalam komputer anda. Waktu yang dibutuhkan untuk selesai loadingnya tergantung dari performa dari komputer yang anda miliki, sebagai perbandingan ketika saya saya menggunakan Pentium 4 dengan memory 512 MB dibutuhkan waktu sekitar 15menit saja. Setelah itu tunggu hingga tampilan layar sebagi berikut

5

Bila tampilan layar di komputer tampak seperti diatas maka berarti intalasi ubuntu di komputer anda telah selesai.
