Radio Online di Linux dan Windows

Seringkan kita klo maen mIRC, trus join ke salah satu channel yang lumayan rame pasti kita melihat bot-bot irc yang promosi Radio Online yang URL nya http://radio.blabla.com:8000/listen.pls. Kira kira gitu deh URL nya… Pernah ga kita kepikir gimana ya buatnya, susah apa gampang sihhh. Gampang aja sih… Yuk kita mulai… Pertama kali, kita download dulu source bisa di ambil di http://shoutcast.com/, pada percobaan ini saya mencoba di Platform Linux SuSe, saya mengambil SHOUTcast Linux server (glibc) v1.9.8. Download dan masukkan ke server linux anda

sebelum mendownload sebaiknya kita membuat folder khusus untuk file streaming radio kita.

[prasetio@disconnected ~]$ mkdir radio
[prasetio@disconnected ~]$

setelah itu kita masuk ke folder radio yang telah kita buat tadi

[prasetio@disconnected ~]$ cd radio
[prasetio@disconnected ~/radio]$

Kini kita sudah berada di folder radio, kini siap untuk mendownload

[prasetio@disconnected ~]$ fetch http://www.shoutcast.com/downloads/sc1-9-8/sc_serv_1.9.8_Linux.tar.gz
sc_serv_1.9.8_Linux.tar.gz 100% of 61 kB 25 kBps
[prasetio@disconnected ~]$

setelah source file server streaming radio sudah di ambil kini kita proses instalasi. Proses instalasi sangat mudah sekali, karena kita disini hanya meng-ekstrak file yang sudah kita download tadi.

[prasetio@disconnected ~/radio]$ tar -zxvf sc_serv_1.9.8_Linux.tar.gz
x README.TXT
x sc_serv.conf
x sc_serv
[prasetio@disconnected ~/radio]$

File sudah di ekstrak, kini kita mempunya 3 buah file, yaitu README.TXT yang isinya sebagai readme dari semua file, sc_serv.conf yang merupakan sebuah config file untuk menjalan radio server, sc_serv merupakan file utama dari server radio kita.

sekarang kita akan menconfig file config agar server radio kita berjalan.. Untuk mengedit config file, gunakan file editor yang ada sukai

[prasetio@disconnected ~/radio]$ nano sc_serv.conf

maka kita akan melihat sederetan config-config dari server radio, disini kita hanya merubah beberapa config, untuk merubah yang lain silahkan anda baca-baca file readme atau baca keterangan di dalam sc_serv.conf

MaxUser=32

Disini kita dapat menentukan berapa maximal user yang dapat mendengarkan radio streaming kita, besar bandwidth internet kita sangat mempengaruhi maximal user, jika kamu punya bandwidth upload sebesar 256KBps dan ingin broadcast lagu dengan rate 24kbps maka kamu hanya dapat mensetting maximal user sebesar 10 orang (256/24=10)

Password=changeme

Password berguna untuk kita broadcast ke server, jika anda ingin memutar lagu dan membroadcast lagu tersebut melalui radio server, maka password ini sangat di butuhkan

PortBase=8000

Portbase merupakan port yang akan di gunakan untuk user yang ingin mendengarkan radio anda, defaultnya adalah port 8000

AdminPassword=adminpass (hilangkan tanda

Merupakan password admin untuk mengakses radio lewat web (web based)

jika semua sudah selesai di config, jangan lupa untuk di save.. Kemudian kita akan menjalankan radionya dengan cara

[prasetio@disconnected ~/radio]$ ./sc_serv

NEC Powermate P5000

Before there were PDAs, Smartphones or ultra-mobile PCs, there were simply desktops and laptops. Since then, this slew of new portable computing devices has swept onto the market, surpassing the laptop in portability, and filling every niche in between. But despite all the new products pushing the smaller-lighter mantra, the divide between laptops and PCs remains a wide one. Outside of bloated “desktop-replacement” laptops, not many machines have attempted to bridge the gap.

NEC’s new PowerMate P5000 ignores the old portable-versus-stationary dichotomy, carving out a niche for what NEC calls the “hybrid PC.” The P5000 takes the compact design of a laptop, the uncompromised interface from a desktop, and rolls them into one. Think “iMac” with a hefty extra dose of portability thrown in.

With a full 17.1-inch LCD screen and a weight of 8.8 pounds, it’s tempting to lump the P5000 in with the aforementioned desktop-replacement laptops and call it day, but the P5000 packs something extra. Unlike any laptop, its wireless keyboard can break away from its screen to be positioned anywhere around it, and a full-size wireless mouse is included as well. If that seems to edge it a little too close to the likes of a the iMac or another one-piece PC, the PowerMate still distinguishes itself by folding up into one compact unit for transport from one place to another with a built-in handle. In design, at least, it truly does find some middle ground.

Under the hood, the PowerMate’s hardware has more in common with a laptop than a desktop. Its AMD Turion X2 TL-52 processor is a mobile unit through-and-through, and the on-board ATI Radeon 1200 graphics processor also pushes things in that direction. Fortunately, there are still some desktop accoutrements, such as four-channel audio (rare on a notebook) and four USB ports. Other specs include a 200GB SATA hard drive, 13-in-1 card reader, built-in Wi-Fi radio, and 1GB or 2GB of DDR2 memory, depending on model.

The PowerMate wasn’t designed to sit in your lap and go anywhere, so users with a need for true mobility will probably want to stick to real notebook computers. However, for situations where laptops are used avoid clutter rather than to provide mobility, the P5000 may be right at home.

Head & Face Color 3D Scanner

The Model 3030 3D scan head is an advanced, general-purpose implementation of Cyberware's proven 3D digitizing technology. The 3030 incorporates a rugged, self-contained optical range-finding system, whose dynamic range accommodates varying lighting conditions and surface properties. Entirely software controlled, the 3030 requires no user adjustments in normal use.

In operation, the 3030 shines a safe, low-intensity laser on an object to create a lighted profile. A high-quality video sensor captures this profile from two viewpoints. The system can digitize thousands of these profiles in a few seconds to capture the shape of the entire object. Simultaneously, a second video sensor in the 3030 acquires color information.

The scanning process captures an array of digitized points, with each point represented by x, y, and z coordinates for shape and 24-bit RGB coordinates for color. The 3030 transfers this data via a USB interface to a graphics workstation for immediate viewing and modification.

Color information in 3D digitizing makes available nearly all the information a graphics application needs to fully describe an object. In addition to enhancing realism in graphic models, color denotes boundaries that are not obvious from shape alone. Color indicates surface texture and reflectance. And by marking an object's surface before digitizing, one can use color to transfer ideas from the object to the graphic model.

In specialized applications, color can reveal characteristics such as skin discoloration, the locations of landmarks, or other features. Working in the infrared region, a customized color subsystem could even detect surface temperature.

The PS motion system is designed to scan the head and face of live subjects quickly, comfortably, and safely. Because the system moves the digitizer while the subject remains stationary, the PS works well in many applications involving subjects that are inconvenient to move during digitizing.

The PS platform is popular for use in medical applications, such as reconstructive and/or plastic surgery and burn mask design. Similarly, designers of products such as helmets, which must fit the human head closely, find the PS motion system ideal. This system also serves well for personal portrait sculpture, in which a person's head is digitized, then reproduced on an automated milling machine or rapid prototyping system with remarkable fidelity.
