Wxpython in Action by Noel Rappin

2010-03-23T13:59:00.000+07:00

Overview:

Because they are often large and complex, GUI programming tool kits can be hard to use. wxPython is a combination of the Python programming language and the wxWidgets toolkit, which allows programmers to create programs with a robust, highly functional graphical user interface, simply and easily. wxPython combines the power of an exceptionally complete user interface toolkit with an exceptionally flexible programming language. The result is a toolkit that is unique in the ease with which complex applications can be built and maintained.

GPS - Making Your Own Data Cables

2010-03-23T11:26:00.023+07:00

Now that you are familiar with the different types of cables that you can combine with your
GPS,it’s time to take a look at how to make some of them.I’ll begin by taking you through the
process of making a data cable.Specifically,this data cable is one for a Garmin eTrex GPS unit.
Materials You Will Need
To successfully build a data cable,you will need the following supplies and tools:

- A suitable connector for your GPS (these are available from www.pfranc.com or
www.lynks.co.uk).
- A cable with a 9-pin D connector on the end—any old serial port cable will do,such as an old
mouse or modem cable.Failing that,you will have to buy a cable).
Soldering iron
- Solder
- Pliers/wire cutters
- Screwdriver (Crosspoint or Phillips)
- Electronic multimeter or circuit tester (if you have a multimeter,it will have an “ohms”
setting—use this for circuit testing).

Cable Assembly You assemble the cable as follows:

1. Take the wire with the 9-pin D connector at one end and cut off any connector at the opposite
end. Cut the outer sheathing off the trimmed end and expose the inner core of wires,as shown in Figure :

2. Strip the ends of the wires,as shown in Figure

3. Using a multimeter,you need to determine which wires corresponds to the data in and
data out and ground pin on the 9-pin connector,as shown in Figure 2-7.To do this,set
the multimeter to “ohms”(the 20 ohms setting will do just fine).Attach one probe to the
bare wire;wrap a length of paper clip around the other probe,and probe the holes in the
connector.Try them in turn;you are looking for a reading of zero,indicating that you
have the right wire for the pin.The pins are as follows:
■ Pin 2:Data out
■ Pin 3:Data in
■ Pin 5:Ground
Carefully note which wires correspond to each pin.If each is colored,make a note ofthis.

4. Trim back all the unneeded wires and cut the wires from pins 2,3,and 5 to a length of
approximately 1 inch (25 mm).Trim the sheath from these wires back about 1 ⁄4 of an
inch (6 mm),as shown in Figure.

5. Now take a look at the pFranc eTrex connector shown in Figure .Notice that it has
four pins.The pins are numbered 1,2,3,and 4,with pin number 1 being the pin furthest
away from the cable.The pins are as follows:
■ Pin 1:Power supply (+)
■ Pin 2:RXD (data in)
■ Pin 3:TXD (data out)
■ Pin 4:GND (-)

6. Time to begin assembly of the pFranc connector.The connector includes five parts:
■ Three plastic parts that make up the connector assembly
■ One metal screw
■ One strip of metal that has the four or eight pins attached to it (depending on the kit you receive),as shown in Figure.

7. Carefully break off the pins (you only need three if you are making a data cable) from the
sheet of metal by bending them off the metal strip.Take care and you will end up with
four pins.

8. After breaking the pins free from the metal strip,bend them to 90 degrees as shown in
below Figure .

9. Now it’s time to solder the wires to the pins.At this stage,it doesn’t matter which pins
the wires are soldered to because you can rearrange them as necessary later.
After soldering,gently push each pin,one at a time,through the hole in the plastic piece
with the large rectangle opening,as shown in Figure .

10. Now you are ready to place the pins in the proper position in the plastic holder (the base
of the connector).The proper assembly is as follows:
■ The wire corresponding to pin 2 (data out on the 9-pin D connector) connects to
pin 3 (data out) on the GPS connector.
■ The wire corresponding to pin 3 (data in on the 9-pin D connector) connects to
pin 2 (data in) on the GPS connector.
■ The wire corresponding to pin 5 (ground on the 9-pin D connector) connects to
pin 4 (ground) on the GPS connector.

The fourth pin is only required if you are making a power cable or a combo cable. If you’re connecting to a 25-pin DB-25 connector, swap over pins 2 and 3 at the PC connector.

A clever way to hold the pins in place while assembling the connector is to use a piece ofwire (or a needle) through the loops of the pins to hold them in place,as shown in this Figure .This is the best hands-free way I’ve found of doing this. Remember to remove the wire after assembly.

Bring the two parts of the connector together and then place the plastic hood on theconnector. Make sure that all the cables seat properly and there is no chance ofshort-circuiting.Then add the screw and close the connector,as shown in Figure. Remove the pin,needle,or wire used to hold the pins in place and the connector is finished

Testing

You should always test your cables before first use to ensure that there are no short circuits or
bad connections.Use a multimeter to do this,as shown in Figure. Make sure that each
pin on the GPS connector corresponds to the appropriate pin on the 9-pin connector.Also
ensure there are no short circuits to any other pins. Refer to your multimeter’s user manual for details on how to operate it.

Allocating Memory and Storing Data

2010-03-23T10:23:00.010+07:00

One reason programmers use Windows API calls is to work with a lot of memory, and you can use the GlobalAlloc (allocate memory), GlobalLock (lock the memory and get a pointer to it), GlobalUnlock (unlock the memory), and GlobalFree (deallocate the memory) functions for that. We’ll take a look at the first two of these
functions in this topic, and the last two in the following topic. We’ll also see how to copy data into and out of our newly allocated memory with the MoveMemory function.

Here’s how you use GlobalAlloc to allocate memory; this function returns a non-zero handle to the memory if successful:

Function GlobalAlloc Lib "kernel32" (ByVal wFlags As Long, ByVal dwBytes As Long) As Long

You set the flags you want to use in wFlags, and the number of memory bytes you want in dwBytes. Here are the possible flags to use with GlobalAlloc:

GMEM_FIXED—&H0
GMEM_MOVEABLE—&H2
GMEM_NOCOMPACT—&H10
GMEM_NODISCARD—&H20
GMEM_ZEROINIT—&H40
GMEM_MODIFY—&H80
GMEM_DISCARDABLE—&H100
GMEM_NOT_BANKED—&H1000
GMEM_SHARE—&H2000
GMEM_DDESHARE—&H2000
GMEM_NOTIFY—&H4000
GMEM_LOWER—GMEM_NOT_BANK
GMEM_VALID_FLAGS—&H7F72
GMEM_INVALID_HANDLE—&H8000

To get a pointer to the memory and so put it to use, you use GlobalLock, passing it the memory
from GlobalAlloc. GlobalLock returns a non-zero pointer to the memory if successful:

Function GlobalLock Lib "kernel32" (ByVal hMem As Long) As Long

Besides GlobalAlloc and GlobalLock, you can move data into the memory you’ve allocated with MoveMemory:

Here are what the arguments to MoveMemory mean:
• dest—Pointer to the destination buffer
• src—Pointer to the source buffer
• length—Number of bytes to move
Let’s see an example. Here, we’ll store a string of text that the user types into a text box in memory; in the next topic in this chapter, we’ll read that string back. This example will give us a good general overview of working with memory and memory buffers.

We start by setting up a 40-character-long buffer for the string to store in the form’s (General) declarations section:

Const DataLength = 40
Dim outbuffer As String * DataLength
...
We also declare the memory handle and pointer we’ll use:
Const DataLength = 40
Dim outbuffer As String * DataLength
Dim hMemory As Long
Dim hMemoryPointer As Long

Finally, we declare the functions we’ll use, GlobalAlloc, GlobalLock, and MoveMemory, as well as the memory flag we’ll use, GMEM_MOVEABLE, which means that Windows can move the memory we are using if it needs to as part of its memory-handling operations:

Const DataLength = 40
Dim outbuffer As String * DataLength
Dim hMemory As Long
Dim hMemoryPointer As Long
Private Declare Function GlobalAlloc Lib "kernel32" (ByVal wFlags As_
Long, ByVal dwBytes As Long) As Long
rivate Declare Function GlobalLock Lib "kernel32" (ByVal hMem As Long) _
As Long
Private Declare Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" _
(ByVal dest As Any, ByVal src As Any, ByVal length As Long)
Const GMEM_MOVEABLE = &H2

When the user clicks a command button, Command1, we will allocate and lock the memory, and store the text string now in Text1 in it. We start by storing the text from the text box in the buffer we’ve named outbuffer:

Private Sub Command1_Click()
outbuffer = Text1.Text
...
Next, we use GlobalAlloc to allocate the memory we’ll use:

Private Sub Command1_Click()
outbuffer = Text1.Text
hMemory = GlobalAlloc(GMEM_MOVEABLE, DataLength)

Next, we pass the memory handle from GlobalAlloc to GlobalLock to get a pointer to the memory we’ve allocated:

Private Sub Command1_Click()
outbuffer = Text1.Text
hMemory = GlobalAlloc(GMEM_MOVEABLE, DataLength)
hMemoryPointer = GlobalLock(hMemory)

Finally, we copy the data from our buffer to our newly allocated memory with MoveMemory (note that because MoveMemory is a subroutine, we use the Call keyword instead of assigning a return value to a variable):

Private Sub Command1_Click()
outbuffer = Text1.Text
hMemory = GlobalAlloc(GMEM_MOVEABLE, DataLength)
hMemoryPointer = GlobalLock(hMemory)
Call MoveMemory(hMemoryPointer, outbuffer, DataLength)
End Sub

And that’s it—when the user clicks Command1, we copy the text string to our allocated memory.
We’ve stored data in allocated memory now—how do we read it back? We’ll take a look at that in the next topic.

Virtual SMSC Implementation and Transit by Agus S

2009-02-28T18:07:00.006+07:00

Business Model

Small or new telecommunications operators may want to minimize their initial capital
expenditures. The virtual SMSC offers these operators a way to provide SMS
service to their customers without buying an SMSC. They use a third-party SMSC
that charges them on the basis of the amount of SMS traffic, so revenues can be generated
without any investment.

Having transit agreements is a way for large or medium operators to get additional
revenues by renting their roaming agreements to a third party (the SMS interworking
network), but they retain full, legal responsibility for their use. The SMS
interworking network will pay the operator for any SMS sent within its roaming
agreements.

The subjects of virtual SMSC and transit agreements are treated within the same
chapter because any third party implementing a virtual SMSC for an operator (main
SMSC or backup SMSC) has access to all roaming agreements for the sending of
SMS-MT as explained in this chapter. The first part of the chapter covers SMS-MO
and virtual SMSCs; the second covers the various implementation of transit agreements.
The only setup is that of STPs or GMSCs to provide specific routing based on
a GT. The third part concerns the implementation of multiple transit agreements in
the same equipment and explains how several international gateways can be
addressed.

Principle of the Virtual SMSC: Architecture and Billing of SMS-MO
Architecture

The provision of SMS service can be entirely subcontracted to an SMS interworking
network. The real SMSC may be in another country, as illustrated by thats Figure on top page.

Teknologi Mengubah Bohlam Lampu menjadi Wi-Fi

2008-12-07T20:11:00.003+07:00

by Carie

Boston University (BU) mengumumkan dimulainya sebuah program yang disponsori National Science Foundation untuk mengembangkan teknologi komunikasi nirkabel yang berbasiskan cahaya, bukan gelombang radio (RF) yang biasa digunakan oleh sinyal Wi-Fi. Ilmuwan berharap teknologi ini kelak dapat digunakan untuk menumpangkan komunikasi data pada light emitting diodes (LED) hemat daya untuk menciptakan “Smart Lighting” yang lebih cepat dan aman daripada teknologi jaringan yang ada saat ini.
Tujuan akhir dari riset ini adalah untuk mengembangkan teknologi komunikasi yang dapat membuat LED setara dengan akses poin Wi-Fi secara fungsional.
“Bayangkan jika komputer, iPhone, TV, Radio dapat berkomunikasi dengan Anda saat memasuki ruangan hanya dengan menekan tombol lampu pada dinding tanpa menggunakan seperangkat kabel,” kata Profesor BU Engineering Thomas Little. “Ini dapat dilakukan dengan jaringan komunikasi berbasis LED yang juga sekaligus menyediakan cahaya — semua ini dengan penggunaan daya yang rendah, dapat diandalkan, dan bebas gangguan gelombang elektromagnetik.

Pada akhirnya, system ini diharapkan dapat menggantikan system pencahayaan yang ada saat ini, seperti mengganti bohlam lampu dengan LED.”
Ilmuwan Boston University akan berkonsentrasi pada pengembangan aplikasi jaringan komputer, khususnya teknologi optik solid state yang kelak akan menjadi tulang punggung jaringan ini.
“Ini adalah kesempatan unik untuk menciptakan teknologi penting yang tidak hanya memungkinkan efisiensi daya dalam pencahayaan namun juga menciptakan teknologi nirkabel yang aman,” tambah Little. “Sembari kita mengalihkan sistem pencahayaan tradisional menjadi LED dalam beberapa tahun mendatang, kita juga dapat secara simultan membangun infrastruktur komunikasi yang lebih cepat dan aman dengan biaya terjangkau bersamaan dengan aplikasi yang baru dan tak terpikirkan sebelumnya.”
Dengan semakin populernya sistem pencahayaan dengan LED, jaringan komunikasi berbasis cahaya besar yang luar biasa besar akan dapat diciptakan. Sebuah alat nirkabel yang berada dalam jangkauan LED dapat mengirimkan dan menerima data melalui cahaya, pada awalnya dengan kecepatan 1 hingga 10 megabit per detik — didukung oleh setiap LED yang berfungsi sebagai akses poin jaringan. Jaringan seperti itu akan menawarkan potensi penggunaan badwith yang jauh labih besar dari teknologi RF yang ada saat ini.
Terlebih lagi, karena cahaya tidak menembus permukaan seperti dinding, teknologi ini juga memberikan tingkat keamanan yang lebih tinggi karena komunikasi data tidak dapat disadap dari luar. Di sisi negatifnya, sifat cahaya ini akan menyulitkan akses jaringan dari ruangan yang berbeda, hal ini berarti juga koneksi jaringan hanya didapatkan saat lampu dinyalakan. Terlebih lagi cahaya LED membutuhkan jauh lebih sedikit daya dibandingkan teknologi RF sehingga akan lebih hemat biaya dalam jangka panjang.

Kerekayasaan Aplikasi SmartCard (Kartu Pintar)

2008-12-02T21:48:00.001+07:00

Secara garis besar Smart card adalah sebuah kartu yang terdiri atas sebuah microprocessor dan sebuah memory card. Atau bisa juga hanya berupa memory card tanpa logic programmable. Microprocessor dapat menambah, menghapus atau memanipulasi informasi pada kartu. Sementara untuk memory-chip hanya dapat digunakan pada aplikasi-aplikasi yang telah didefinisikan sebelumnya.

Smart card, tidak seperti magnetip stripe, dapat membawa informasi dan operasi yang dibutuhkan pada kartu. Oleh karena itu, dengan menggunakan smart card, kita tidak perlu mengakses database pada saat transaksi.Smart card tidak memiliki batrei, dan akan aktif ketika tersambung dengan card reader. Ketika tersambung dengan card reader, kartu akan bersifat pasif untuk menerima perintah dari aplikasi client.Smart card dapat berupa contact atau contactless. Sesuai dengan namanya, komunikasi dengan contact smart card mengharuskan kontak secara fisik antara card reader dengan smart card yang terdiri atas 8-pin contact, sementara contactless, komunikasi berlangsung melalui sinyal frekuensi radio, dengan batas maksimum 2 kaki.
Aplikasi Smart CArd lebih banyak dikembangkan dengan platform JAVA, untuk menambah kasanah dan pemahaman yang lebih mudah dimengerti maka telah saya develop dengan bahasa Visual Basic, screenshoot diatas adalah Program Smart Card Reader yang dimaksudkan.
Aplikasi ini memiliki fungsi sejumlah 22 fungsi dari berkas pustaka SCARD32.DLL,
agar dapat berfungsi pada card reader anda, anda harus mendownload file SCRAD32.DLL terlebih dahulu.

Aplikasi Location Base System (LBS) #1

2007-07-07T17:41:00.000+07:00

Aplikasi Location Base System (LBS) untuk Mobile Advertising berbasis J2ME Aplikasi LBS ini akan melakukan beberapa proses berikut :
- Aplikasi diaktifkan
- Ketika aplikasi J2ME kita mendapati CellID berubah, maka dia akan mengirimkan informasi itu ke Application Server untuk memproses berikut :

* mengambil informasi lokasi dari CellSpotting.com berdasar CellID saat ini (untuk melakukan ini, dari J2ME membuat koneksi dengan protokol HTTP methode POST agar dapat mengambil data dari database CellSpotting.com)

* mencari di database, iklan-iklan yang terdaftar di sekitar area CellID tersebut * setelah ditemukan, langsung dikirim kembali ke ponsel melalui SMS Catatan: - perlu diketahui bahwa database di cellspotting.com masih sangat terbatas, karena tergantung pada para pemakai yang memasukannya - kesulitan utama dalam penelitian ini adalah:

* mendapatkan data BTS berdasar CellID
* saat ini JSR 179 (untuk LBS) masih sangat terbatas diterapkan contoh ponsel yang sudah implementasi JSR 179:

http://www.forum.nokia.com/main/0,,018-2675,00.html?model=6265
* karena sebagian besar konfigurasi BTS di indonesia menjangkau area yang cukup luas, maka perlu batasan sistem yang sangat jelas di sini

Arabic Symbology
Although Arabic is SBCS language, it present a special challenge to programmers. Because they’re script language traditionally written with a pen, a character can take on a different shape depending on where it appears in a word. This is similar to use capital letters at the beginning of European and American words. Many Arabic characters, however, have four variations for when the character appears at the beginning, middle, or end of a word and for when it appears by itself. More...

SOA (Service Oriented Architecture)

2007-07-04T21:50:00.000+07:00

Service Oriented Architecture (SOA) merupakan satu konsep yang sedang hangat diperkatakan dan diperdebatkan dalam dunia IT beberapa tahun yang lepas. Hal ini merupakan paradigma dan konsep baru bagi mengoptimakan sebuah organisasi yang menggunakan teknologi IT agar dapat dimanfaatkan oleh organisasi lain yang memerlukannya, dengan mewujudkan sambungan (link), mengikut protokol tertentu antara organisasi berkenaan.

Protokol tersebut merupakan sesuatu yang boleh diterima oleh semua organisasi di atas platform yang berbeda. SOA perlulah diinspirasi oleh organisasi yang berasaskan manusia (human organization) dan seterusnya diterjemahkan kepada bahasa mesin dan teknologi. Layanan service, perlulah dirujuk kepada fungsi organisasi berkenaan, yang boleh ditawarkan kepada organisasi lain. Informasi yang ditawarkan perlulah dikawal oleh peraturan yang diwujudkan oleh organisasi berkenaan, atau badan lain untuk memastikan dan mengawal kualitas informasi yang bersangkutan, dan yang penting sekali untuk menentukan apakah informasi boleh diakses oleh organisasi lain.

Dari segi informasi, SOA adalah satu paradigma untuk pengaturan(organizing) dan penggunaan (utilizing) manfaat yang dapat diambil dan berada dibawah pengawasan pemilik domain yang berbeda. Capability boleh dilihat sebagai service yang diberikan oleh pelbagai organisasi yang berada pada lokasi yang berbeda.

Sudah pasti, organisasi perlu memahami konsep SOA, dan bersedia(willing) untuk menyediakan informasi tertentu melalui konsep SOA, menyediakan kaidah tertentu untuk interaksi dengan organisasi lain -communication, memastikan informasi agar dapat dilihat (visible) oleh organisasi lain dan yang panting sekali, bersedia untuk berkongsi data dan maklumat dengan organisasi lain (Sharing).

Sharing informasi dan data, tidaklah mudah dan bersifat ‘plug n play’, karena tidak akan bersahaja melihat dari sudut syntax(struktur/format) saja, tetapi juga makna dan maksud (semantic) .

Informasi Peta Multi Routing
Menggunakan GOOGLE MAPS, Ir Agus S

Google Maps menyediakan fitur untuk menampilkan Peta Routing (Direction) dengan menggunakan parameter HTTP.

Misalny kita hendak mendapatkan DIRECTION dari kota Minneapolis, MN menuju kota New York melewati kota San Fransisco dan Tampa, maka string parameter HTTP dapat secara langsung diketikkan pada adress web browser dengan syntax sebagai berikut

http://maps.google.com/maps?saddr=start+address&daddr=destination+address

implementasi sintaksis DIRECTION dari Source (Kota Minneapolis) ke Destination (Kota Tujuan New York) melewati kota San Fransisco dan Tampa menjadi sbb :

http://maps.google.com/maps?
saddr=minneapolis%2C+mn& daddr=san+francisco%2C+ca+to%3Atampa%2C+fl+
to%3Anew+york%2C+new+york

Agar lebih customize bagi user dan memberikan Information Value yang lebih aplikatif, kita dapat mengembangkan aplikasi untuk mengolah data spasial menggunakan fasilitas dari Google Maps tsb. dengan menggunakan bahasa pemrograman Delphi, VB, C dsb, sehingga dapat memberikan output berupa informasi Direction Map, waktu tempuh dan lain sebagainya.

This proved to be cumbersome and yielded inconsistent results, so some time was invested in designing a database to store the content of djstein.com in a relational database and to write documents in standardized form. The resulting application is an intermediary between a set of simple user forms and the HTML content of the website. (Most CMSes are web applications that generate this text on-the-fly. But djstein.com is a website with infrequent changes, so it is more efficient to generate static HTML in response to site changes. Thus, the database is hosted remotely, and pages are generated remotely and deployed to the djstein.com webserver.)

SerReg is a small home controller intended to turn your personal computer ( PC ) into a process control / data collection system. With the appropriate sensors SerReg can monitor physical variables such as pressure, temperature, light intensity, weight, movement etc, process the information and then use the result to control up to three physical devices such as motors, heaters, sirens, lights or other appliances around the home, office, laboratory or factory . You can program your appliances to operate automatically in conjunction with your weekly and daily schedule, manualy turn them on/off from your PC or use SerReg as a process ON/OFF controller to regulate some kind of physical variable ( process variable - PV ) to the desired value ( setpoint - SP ).

Hasil Tes Aptitude Pemrograman Mhs. Thn I United Kingdom

2007-02-03T16:58:00.000+07:00

Saeed Dehnadi dan Richard Bornat (paper pdf) melakukan sebuah tes apititude pemrograman
Learning to program is notoriously difficult. A substantial minority of students fails in every introductory programming course in every UK university. Despite heroic academic effort, the proportion has increased rather than decreased over the years. Despite a great deal of research into teaching methods and student responses, we have no idea of the cause.
It has long been suspected that some people have a natural aptitude for programming, but until now there has been no psychological test which could detect it. Programming ability is not known to be correlated with age, with sex, or with educational attainment; nor has it been found to be correlated with any of the aptitudes measured in conventional intelligence or problem-solving-ability tests.

We have found a test for programming aptitude, of which we give details. We can predict success or failure even before students have had any contact with any programming language with very high accuracy, and by testing with the same instrument after a few weeks of exposure, with extreme accuracy. We present experimental evidence to support our claim. We point out that programming teaching is useless for those who are bound to fail and pointless for those who are certain to succeed.
Berdasarkan hasil pengujian mereka, terdapat tiga kelompok dalam kelas pemrograman,

Kelompok yang ingin belajar lebih cepat
Kelompok yang mengatur diri dan berusaha supaya lulus
Kelompok yang belum memahami ide dasar pemrograman (sampai perkuliah selesai)

Tampaknya kesalahan bukan pada dosen (baik dari material maupun cara mengajarnya):
The cause isn’t to be found in inappropriate teaching materials or methods either. Essentially, the computer science community has tried everything (see section 2) and nothing works. Graphics, artificial intelligence, logic programming languages, OOP, C, C++, PROLOG, Miranda: you name it, we’ve tried it. We’ve tried conventional teaching, lab-based learning by discovery and remedial classes. We’ve tried enthusiasm and cold- eyed logical clarity. Nothing makes a difference. Even the UK’s attempt in the 1980s to teach the whole UK population to program on the BBC Micro ran into the sand.

Tips Mendesign Website

2007-02-03T09:48:00.000+07:00

Sering kita temui website yang tipikal: "Welcome to my homepage," animasi e-mail, background dengan tulisan miring (diagonal), animasi garis pembatas, tabel dengan border tiga-dimesi dan lain-lain. Hal ini terjadi akibat dari fasilitas Template yang disediakan oleh software pembuat web seperti: FrontpageT, Corel WebDesignerT, dan sebagainya yang ditujukan untuk mempermudah penggunanya dalam membangun website.
Jika anda puas dengan hasil kerja anda membangun website dengan fasilitas template, sudahlah cukup sampai disini. Tetapi jika anda tidak puas dengan apa yang anda buat, dan anda merasa ingin lebih baik, maka anda perlu mengetahui bagaimana Web Designer membangun suatu Website, terlepas anda punya bakat seni atau tidak.
Unik : Dalam membuat karya apapun seorang designer mempunyai kesadaran untuk tidak meniru atau menggunakan karya orang lain. Begitu pula seorang Web Designer harus mempunyai budaya malu untuk menggunakan icon, animasi, button, dll, yang telah digunakan atau dibuat oleh orang lain.
Komposisi : Seorang Web Designer selalu memperhatikan komposisi warna yang akan digunakan dalam website yang dibuatnya. Pergunakan selalu Palette 216 WebColor, yang dapat diperoleh dari Adobe.com, hal ini untuk mencegah terjadinya dither pada image yang berformat GIF. Dalam membangun website suatu perusahaan, Web Designer selalu menyesuaikan warna yang digunakan dengan Corporate Color perusahaan tersebut. Sebagai contoh: Telkom Corporate Color-nya adalah biru, Coca-Cola : merah dan putih, Standard-Chartered : hijau dan biru, dsb. Untuk kemudian warna-warna tadi digunakan sebagai warna dominan atau sebagai elemen pendukung (garis, background, button, dsb).
Simple : Web Designer banyak yang menggunakan prinsip "Keep it Simple", hal ini ditujukan agar tampilan website tersebut terlihat rapi, bersih dan juga informatif.
Semiotik : Semiotika adalah ilmu yang mempelajari tentang tanda-tanda. Dalam hal ini diharapkan dengan melihat tanda atau gambar, user/ audience dapat dengan mudah dan cepat mengerti. Sebagai contoh: Jangan membuat gambar/image yang berkesan tombol, padahal itu bukan tombol/ link.
Ergonomis : Web Designer selalu memperhatikan aspek ergonomi. Ergonomi disini adalah dalam hal kenyamanan user dalam membaca dan kecepatan user dalam menelusuri website tersebut. Web Designer memilih ukuran Fonts yang tepat sehingga mudah dibaca, Web Designer menempatkan link sedemikian rupa sehingga mudah dan cepat untuk di akses dan lebih penting lagi adalah Informatif.
Fokus : Tentukan hirarki prioritas dari pesan yang akan disampaikan, misalnya: Judul harus besar, tetapi jangan sampai akhirnya akan konflik dengan subjudul yang berukuran hampir sama. Hal ini akan membingungkan user/audience untuk menentukan pesan mana yang harus lebih dahulu dibaca/ dilihat.
Konsisten : Tentukan font apa yang akan digunakan sebagai Body-text, Judul, Sub Judul dan sebagainya, sehingga website tersebut akan terlihat disiplin dan rapi. Sesuaikan jenis huruf yang digunakan dengan misi dan visi website tersebut, misalnya: hindari menggunakan font Comic dalam membangun website suatu perusahaan resmi. Demikian beberapa aspek dan prinsip yang digunakan Web Designer dalam membuat website, selebihnya merupakan ekspresi dari pembuat website itu sendiri yang terwujud dalam penggayaan penyusunan website.
