membuka situs yang diblokir

Beberapa situs yang ada di Internet memang kadang-kadang membuat kita lupa waktu ketika mengakses Web tersebut, contohnya facebook, friendster dsb, hal ini mengakibatkan beberapa internet share memblokir situs-situs tersebut, biasa nya blokir web ini dilakukan oleh tempat-tempat seperti di kantor, kampus dll.
Nah, khusus situs-situs yang di blokir melalui server ini kita ternyata bisa juga nembus web-web yang di blok tersebut, caranya mudah, kita tinggal pake proxy saja , jadi intinya kalo kita menggunakan proxy adalah komputer kita tidak akan me-request IP komputer yang sebenarnya.
Jadi kalo di ilustrasikan begini:
Tanpa Proxy: Komputer kita–>Website
Dengan proxy: Komputer Kita–>Komputer Lain–>Website




Jadi secara tidak langsung kita mengakses web yang terblokir tapi dengan terlebih dahulu “dijembatani” oleh komputer lain, sehingga IP yang kita kunjungi bukan lagi dari IP web yang terblokir, melainkan dari IP komputer lain. dan untuk mengubah proxy bisa dilakukan dengan cara di bawah ini:
Mozilla firefox:
- Tools –> Options
- Lalu kita memilih “tab Advanced”–>dan dilanjutkan dengan “tab Network” –> kemudian kita klik Setting
- kita Klik opsi “ Manual proxy configurations “ –> dan kemudian kita isikan nomor IP Proxy server yang bisa di cari di Proxy4free.com, misalnya : 313.287.279.221 dan portnya : 8888.
- Dan pada sesi yang terakhir kita kasih ceklist di “ Use this proxy for all protocol “
Internet Exploler :
- Pilih “Menu Tools”–>Kemudian klik “Internet Options”–>Lalu klik “tab Connections”.
- Lalu setelah itu pilih “LAN Setting” –>Kemudian kasih ceklist di opsi “ Automatically detect setting “ –>lalu di pilihan “Proxy server”, ceklist optional “ Use a proxy server for LAN”.
- Lalu pada step ini silahkan isi nomor proxy, misal : 313.204.279.221 dan di port : 8888. kemudian pada langkah terakhir ceklist “Bypass proxy server for local address” , dan OK.

cara membuat web/blog versi mobile

Sudah banyak web sekarang yang menggunakan versi mobile, seperti friendster.com yang menjadi m.friendster.com, Facebook.com menjadi m.facebook.com, detik.com menjadi m.detik.com, kask.us menjadi m.kask.us dll, memang tampilan nya kurang memuaskan, memang ini merupakan salah satu kekurangan nya, tetapi ada juga kelebihan nya, yaitu web/ blog kita bisa di buka di HP dengan bandwidth yang relatif sedikit.
Kemajuan penggunaan handphone saat ini memang sudah sangat maju, sehingga untuk mengunjungi sebuah web atau blog dapat dengan browser di HP saja. Nah mulai sekarang mobilisasi kan web/blog kamu!
Nah berikut ini cara untuk bagaimana membuat web/blog anda ke versi mobile:
1. Masuk ke website mofuse.com
2. Lalu register/create an account ke web tersebut (mofuse.com)
3. Setelah itu anda klik “Get Going! Create a New Mobile Site!”
4. Lalu anda anda diminta untuk isi form tentang identitas blog anda.
5. Setelah langkah 4 selesai maka klik “Launch Your Mobile Site”.
Selesai!, sekarang anda sudah mempunyai web/blog versi mobile.

ATI Radeon HD 5970 : A Real Monster

The new graphics card is monstrous because it virtually doubles the already impressive specs of a single Radeon HD 5870. The choice of the Hemlock’s official model number is somewhat odd since the Radeon HD 5970 uses the same graphics chips as the Radeon HD 5800 series. For example, the Radeon HD 4890 used to have an RV790 processor, which was a greatly revised version of the RV770, but this only affected the third rather than second numeral in its model name. A model name like Radeon HD 5870 X2 would look reasonable enough, but ATI must be willing to finally unify and standardize its product nomenclature by getting rid of the numerous suffixes and additions in product names that used to confuse customers before.
Now, let’s take a look at the Radeon HD 5970’s specs:

ATI’s engineers could not repeat the same trick as with the Radeon HD 4870 X2, on which they had installed two RV770 cores and two sets of GDDR5 memory chips without lowering the clock rates. The trick did not work with the Radeon HD 5970. To keep the new card’s heat dissipation within reasonable limits, the GPU and memory clock rates have been reduced from 850 to 725MHz and from 1200 (4800) to 1000 (4000) MHz, respectively. We wouldn’t worry about that if CrossFire technology worked at all times. The reduced GPU frequencies would be made up for by the double amount of computing and texture-mapping resources whereas the graphics memory bandwidth is colossally high even at the reduced clock rate. But we know that every implementation of the multi-GPU concept available today depends on software support on the side of the driver and game engine. So, if a 3D application proves to be incompatible with ATI CrossFire technology, the Radeon HD 5970’s performance may fall below the level of the Radeon HD 5870 whose single processor is clocked at 850MHz and does not need any special software support. Considering that the Radeon HD 5970 comes at a recommended price of $599, this may be quite disappointing.
Anyway, the Radeon HD 5970 is indeed the highest-performance single graphics card on this planet. And it is going to enjoy this status for a long while. The official announcement of Nvidia’s GeForce 300 series is postponed to 2010. Nvidia’s new core codenamed Fermi is far more complex than the RV870 Juniper and dual-processor Fermi-based cards won’t come out soon (if such products will be released at all) while single-processor Fermi-based solutions are going to be inferior to the Radeon HD 5970 in performance. The new card is all about big numbers: 640 unified execution processors, 3200 ALUs, 160 texture-mapping modules and 64 RBEs. Such specs are going to entice even the most skeptically-minded gamer to shell out 6 hundred bucks. As a matter of fact, nothing – except for financial considerations – prevents you from purchasing two such cards and building a truly marvelous CrossFireX subsystem capable of delivering playable frame rates even at a resolution of 7680x1600 pixels! 
Developing this graphics card was not easy for ATI’s people. Particularly, they had to renovate the cooling system of the Radeon HD 4870 X2 which had been criticized widely. Running a little ahead, we can say that the task has been solved well. The two RV870 are not just effectively cooled. The new cooler is good at overclocking and AMD puts an emphasis on that. We will discuss this issue later on. Right now, let’s take a closer look at the Radeon HD 5970 itself.
