    5. List of running applications aka task manager
    “Home” key (long key press) any time, any where

    6. Another used of back space key
    During the listing of sms or notes, use Tip 1 to select the desire sms or notes then press “back space” to delete the sms or notes.

    7. Additional short cut keys to launch application
    Other then “Left selection key” & “Right selection key”, “navigation keys” (left, right, up & down) can also be used to launch applications. The “navigation keys” can be set through “Menu -&gt Tools -&gt Settings -&gt General -&gt Personalisation -&gt Home Screen -&gt Key shortcuts” (long deep menus…).

    The other way to launch application using shortcut key can also be done with the “One-touch″ keys. Its config can be accessible through “Menu -&gt Tools -&gt Settings -&gt General -&gt Personalisation -&gt One-touch″. There are 3 keys available but with combination of “Short press” & “Long press”, it can set up to maximum of 6 shortcuts. As for the “Home” key, it is not available as by default the short key press is set to “Menu” and long key press is set to “List of applications” aka Task Manager.

    8. Quick search on contact during sms
    Type in the search criteria on the “To:” field at the top then press the center button of the “navigation” button and the valid search list will appear.

    9. Page up, page down for scrolling

    Wireless Mesh Networks: Example and Application

    En March 31, 2009
    Categorias: Network

    Example of three types of wireless mesh network:
    Wireless Infrastructure-mesh networks: mesh routers form an infrastructure for customers.
    Client-mesh wireless networks: the nodes are the customer’s route network to carry out the configuration and functionality.
    Hybrid wireless mesh networks: Mesh clients can perform mesh grid with other clients, as well as access to the network. Wireless mesh network having a relatively stable topology except for the occasional lack of nodes or adding new nodes. The traffic is aggregated from a large number of end users, changes infrequently. Virtually all traffic in an infrastructure mesh network that is transmitted to or from a gateway, while in ad hoc networks or mesh client network traffic flows between arbitrary pairs of nodes.

    Applications
    Mesh networks may involve either fixed or mobile devices. The solutions are as varied as the needs of communication, e.g. in harsh environments such as emergency situations, tunnels and oil rigs to battlefield surveillance and high-speed mobile video applications on board public transport or Real-time racing car telemetry. An important application of wireless mesh networks is VoIP. By using a Quality of Service scheme, the mesh can support wireless local telephone calls are made through the mesh.
    Management

    This type of infrastructure can be decentralized (with no central server) or centralized (with a central server); both are relatively inexpensive and very reliable and resilient, as each node must transmit only in so far as the next node. Nodes act as routers to transmit data from nearby nodes to peers that are too far away to reach in one leap, resulting in a network that can span long distances. The topology of a mesh network is also more reliable, as each node is connected to other nodes. If you drop a node on the network due to hardware failure or any other reason, neighbors can find another route using a routing protocol.
    Operation

    The principle is similar to the way packets travel around the Internet Wired – data hop from one device to another until it reaches its destination. Dynamic routing algorithms implemented in each device allow this to happen. To implement such dynamic routing protocols, each device must communicate routing information to other devices on the network. Each device then determines what to do with the data it receives – either pass it to the next device or keep it, according to the protocol. The routing algorithm used should always try to ensure that data is most appropriate (fastest) route to your destination.

    Wireless Mesh Networks: Technology and Definition

    En March 31, 2009
    Categorias: Network

    Currently, wireless networks offer a number of advantages, one is able to access internet on our PC from any point where we are, and always good when our computer has the necessary components in order to access this type of connection. But in the beginning this type of wireless infrastructure was costly, since we still were needed cables to connect computers (nodes) between them.
    With mesh technology in the wireless network could eliminate this kind of disadvantage, as the inclusion of such technology can be installed quickly and easily. To operate, each node needs nothing but power.
    The mesh technology using WiFi standards set in an innovative way. The set of nodes provides a WiFi coverage area, or an access point, an area in which the user can surf the internet without cables, using your laptop. The nodes are capable of establishing a connection between themselves regarding their coverage areas overlap, if multiple overlapping zones of coverage, but fail one or more nodes, the network is sustained and continues to operate. You probably not aware of this, because your computer will automatically connect to the next access point in the network.

    MESH Technology
    A wireless mesh network (WMN) is a radio communication network of nodes arranged in a mesh topology. The coverage area of the radio nodes working as a single network is sometimes called a mesh cloud. Access to this mesh cloud is dependent on the radio nodes working in harmony with one another to create a radio network. A mesh network is reliable and offers redundancy. When a node can no longer work, the remaining nodes can still communicate with each other directly or through one or more intermediate nodes.
    A wireless mesh network can be viewed as a kind of ad hoc wireless network where all nodes are static and radio not the direct experience of mobility.

    Network structure
    Wireless mesh architecture is a first step towards providing high-bandwidth network through a coverage area. Architecture wireless mesh infrastructure is, in effect, a network router unless the wiring between the nodes. These are pairs of radio devices that do not have to be connected to a wired port traditional WLAN as access point (AP) do. Mesh architecture sustains signal strength by breaking long distances in a series of short jumps. Intermediate nodes not only boost the signal, but forwarding to make cooperative decisions based on their knowledge of the network, perform the routing. That may this architecture with a careful design to provide wide bandwidth, spectral efficiency and the economic advantage of the coverage area.

    Macam-Macam Teknik Data Recovery

    En February 22, 2009
    Categorias: Computer

    Di bawah ini adalah beberapa teknik data recovery yang bisa kita terapkan jika kita menghadapi masalah hard disk terutama yang berhubungan dengan physical failure.

    Mengganti Circuit Board / PCB
    Teknik ini sempat saya coba beberapa tahun lalu ketika hard disk 13Gb saya terbakar. Teknik ini harus dilakukan dengan hati-hati jangan sampai merusak salah satu komponen dalam hard disk.

    Mengganti Firmware
    Firmware pada hard disk adalah informasi yang digunakan oleh komputer yang mengijinkan komputer itu ‘berkomunikasi’ dengan hard disk. Firmware bisa diganti dengan yang terbaru.

    Mengganti Head Stack
    Kalau di tape ada yang namanya head, di hard disk juga ada yang namanya head. Di tape biasanya kalau lagu gak jernih, head-nya bisa kita bersihin pake tape-head-cleaner. Tapi kalau head di hard disk bentuknya sangat kecil sekali, seperti chip berukuran kecil yang berada dalam head stack yang dinamakan Preamplifier. Untuk mengganti head stack lebih baik di kerjakan dalam sebuah tempat yang benar-benar secure karena kesalahan kecil bisa menyebabkan kerusakan fatal.

    Memindahkan Disk ke Hard Disk Lain
    Jika circuit board yang berada di luar hard disk dan komponen-komponen dalam hard disk seperti head stack tadi rusak dan hanya kepingan disk yang masih berfungsi, data recovery bisa dilakukan dengan cara memindahkan disk tersebut ke hard drive lain.

    Spin-Stand Testers
    Spin-Stand ini digunakan untuk melakukan test terhadap hard disk terutama pada preamplifier dan read channel suppliers agar bisa berfungsi dengan akurat. Tester ini sering dipakai oleh pabrik hard disk.

    Magnetic Force Microscopes (MFM)
    Magnetic Force Microscopes adalah sebuah tool yang sangat mutakhir untuk high-resolution magnetic imaging dari hampir semua media storage. Data recovery menggunakan Magnetic Force Microscopes ini merupakan data recovery yang canggih, jadi memang harus dilakukan oleh ahlinya.

    Intel Virtualization Technology

    En February 22, 2009
    Categorias: Computer

    Intel Virtualization Technology adalah teknologi yang memungkinkan sebuah processor bekerja seperti memiliki beberapa processor yang masing-masing bisa menjalankan operating system yang berbeda beserta program-programnya secara bersamaan.

    Virtualization Technology ini sebenarnya bukan hal baru. Dulu pada jaman memakai 486DX2, sebenarnya teknologi ini sudah dikenal. Yang mana saat itu bisa membuat beberapa virtual machine yang menjalankan operating system atau program-program/games under DOS secara bersamaan.

    Saat ini ada beberapa software di pasaran yang mampu membuat virtualization technology seperti ini, seperti VMware yang merupakan salah satu software yang paling terkenal. Walaupun kita bisa memanfaatkan software-software seperti VMware untuk virtualization technology ini, menggunakan processor yang memiliki feature virtualization technology ini sebenarnya memberikan keuntungan lebih seperti selain ada banyak instruksi-instruksi baru yang memudahkan pengaturan virtualisasi itu sendiri tentu saja memberikan performance yang lebih baik dibandingkan hanya mengandalkan software.

    Mungkin Anda bingung membedakan Virtualization dengan Multitasking atau bahkan dengan Hyperthreading. Pada teknologi multitasking yang berjalan hanya 1 sistem operasi dengan beberapa program yang dijalankan di dalamnya. Pada virtualization technology, kita bisa menjalankan beberapa sistem operasi secara bersamaan dan masing-masing sistem operasi tersebut bisa menjalankan beberapa program. Masing-masing sistem operasi ini berjalan pada Virtual Machine atau Virtual CPU. Sedangkan teknologi hyperthreading mensimulasikan 2 CPU pada 1 CPU yang berfungsi untuk menyeimbangkan performance menggunakan SMP (Symmetric Multi Processing) dan kedua CPU tersebut tidak bisa dipakai secara terpisah.

    Dasar-dasar Program Affiliasi

    En January 30, 2009
    Categorias: Business

    Ringkasan : Disini akan diberikan pengertian dasar tentang program affiliasi, apa dan bagaimana cara kerjanya.

    Program Affiliasi (juga dikenal sebagai program referral atau program partnership/ kemitraan) menawarkan sebuah cara untuk memanfaatkan traffic yang datang ke website anda untuk memberikan pendapatan (uang) bagi anda, tanpa perlu repot dan biaya untuk menjual sesuatu. Sebaliknya anda mendapat komisi karena telah menciptakan sebuah transaksi. Apa yang disebut “transaksi” dan berapa nilainya, berbeda untuk setiap program affiliasi.

    Program Affiliasi umumnya ditawarkan oleh situs yang menjual barang atau jasa, walaupun ada juga yang menawarkan transaksi dalam bentuk lain, seperti misalnya dengan membawa pengunjung untuk mendaftar untuk berlangganan free newsletter, mengisi formulir, atau sekedar mengunduh sebuah screensaver.

    Kebanyakan program affiliasi memberi komisi berdasarkan persentase pendapatan yang terjadi akibat pembelian dari pengunjung yang berasal dari website anda. Sebagai contoh, jika anda berpartisipasi dalam sebuah program affiliasi yang menawarkan komisi 10% dan anda mengirimkan seorang pengunjung yang membeli barang seharga $100, maka anda akan mendapat komisi sebesar $10. Besar komisi bervariasi mulai dari 1% (biasanya untuk barang mahal dari produsen terkenal) hingga 50% (biasanya untuk barang kecil seperti eBook,dll).

    Sebagian program affiliasi menawarkan Pay-per-lead ketimbang Pay-per-sale – dengan arti kata, anda membawakan mereka calon pelanggan dan mereka membayar komisi yang besarnya telah ditetapkan, sebagai “imbalan” atas peluang yang mereka dapatkan untuk memasarkan barang/jasa bagi calon pelanggan tersebut. Praktek affiliasi model ini banyak diselenggarkan oleh industri asuransi dan kartu kredit.

    Ada juga model affiliasi lain yang menawarkan pembayaran (dengan nilai yang sangat kecil) untuk setiap pengiriman pengunjung ke sebuah situs, atau pembayaran untuk setiap unit iklan yang tertayang (biasanya berupa banner atau iklan pop-up/pop-under). Program affiliasi demikian memberikan pembayaran tanpa memandang apakah seorang pengunjung berubah menjadi pelanggan mereka atau tidak.

    Apabila anda bergabung dalam sebuah program affiliasi, anda akan diberikan sebuah URL (atau serangkaian URL) berformat khusus yang akan anda pergunakan untuk menciptakan link ke situs pemilik/provider program affiliasi tersebut. Hal ini akan memungkinkan provider affiliasi (bisa produsen barang/jasa, atau pihak ketiga atas nama produsen barang/jasa) untuk menelusuri traffic yang berasal dari website anda dan mencatat apabila ada tindakan (pembelian,pengisian form, dll) berlangsung.

    Kesimpulan :

    Program affiliasi sangat beragam dalam hal kualitas dan keandalan menyeluruh, tingkat komisi yang ditawarkan, bentuk dan cakupan bantuan/dukungan dari situs induk yang ditawarkan dalam memasarkan produk atau jasa yang dijual, dan sebagainya. Dengan memahami benar apa dan bagaimana cara kerja program affiliasi, anda diharapkan mampu meminimalkan resiko tidak dibayar, serta memaksimalkan potensi pendapatan anda.
