Mempercepat Akses Internet

Saat anda browsing atau membuka suatu website di internet entah dari warung internet ataupun dari rumah, mungkin anda sering mengeluh akan lambatnya akses untuk menampilkan website tersebut. Padahal akses internet di Indonesia sekarang ini masih terhitung mahal.

Sebenarnya ada cara-cara mudah untuk meningkatkan kecepatan akses internat anda tanpa harus membayar biaya lebih mahal. Beberapa diantaranya adalah dengan menyetting browser kita, menggunakan openDNS, dan menggunakan Google Web Accelerator.Untuk menerapkan trik-trik tersebut sangat mudah.

Cara pertama yaitu menyetting browser dapat dilakukan oleh pengguna Internet Explorer dan Mozilla Firefox. Bagi pengguna Internet Explorer klik menu [Tools] [Internet Option], klik tab [General]. Pada opsi “Temperory Internet files”, klik [Settings] lalu Geser slider-nya. Hal itu untuk membuat cache (lokasi penyimpanan sementara) untuk web yang anda buka, sebaliknya disediakan sekitar 5% dari Hard disk.


Bagi pengguna Mozilla Firefox anda dapat mengetikkan “about:config” pada address bar,. setelah itu ubah “network.http.pipelining” dan “network.http.proxy pipelining” menjadi “true”, serta isi “network.http.pipelining.maxrequests” antara 30 –100 ( semakin besar semakin cepat ). Yang terakhir klik kanan dimana saja dan pilih New->Integer , tuliskan “nglayout.initialpaint.delay” lalu isi dengan 0.



Untuk trik kedua, pertama anda harus mendaftar di www.openDNS.com . Setelah itu masuk ke Control Panel dari start menu, pilih network connections lalu pilih koneksi anda dan klik tombol properties. Pada bagian Internet protokol anda bisa pilih TCP/IP dan klik properties. Masukkan angka 208.67.222.222 dan 208.67.220.220 pada opsi DNS dan restart komputer anda.



Setelah melakukan 2 tips di atas sekarang anda pasti akan mendapat kecepatan akses yang lebih kencang. Bagi yang masih belum puas dengan kecepatan aksesnya sekarang dapat menggunakan trik yang ke tiga yaitu Google Web Accelerator. Google Web Accelerator di desain khusus untuk mempercepat akses internet anda, khususnya anda yang menggunakan koneksi broadband (pita lebar) seperti Cable dan DSL. Untuk anda yang menggunakan koneksi lain seperti Dial-up (Telkomnet Instant atau Speedy) maupun satelit atau wave, Google Web Accelerator juga dapat mempercepat aksesnya.



Untuk memakai Google Web Accelerator anda harus memenuhi kriteria antara lain Operating System anda harus Windows XP atau Windows 2000 dan browser anda harus Internet Explorer 5.5+ atau Mozilla Firefox 1.0+. Kalau untuk browser lainnya sebenarnya juga bisa, tetapi anda harus meng-konfigurasi proxy settings dari browser anda dengan menambah 127.0.0.1:9100 pada HTTP. Setelah anda melakukan instalasi, Google Web Accelerator akan menampilkan icon kecil di atas browser anda dan icon tray di pojok bawah layar komputer.



Anda dapat mengunduh Google Web Accelerator di http://webaccelerator.google.com

DNA Evidence Can Be Fabricated

DNA Evidence Can Be Fabricated, Scientists Show - NYTimes.com

Scientists in Israel have demonstrated that it is possible to fabricate DNA evidence, undermining the credibility of what has been considered the gold standard of proof in criminal cases.

The scientists fabricated blood and saliva samples containing DNA from a person other than the donor of the blood and saliva. They also showed that if they had access to a DNA profile in a database, they could construct a sample of DNA to match that profile without obtaining any tissue from that person.

“You can just engineer a crime scene,” said Dan Frumkin, lead author of the paper, which has been published online by the journal Forensic Science International: Genetics. “Any biology undergraduate could perform this.”

Dr. Frumkin is a founder of Nucleix, a company based in Tel Aviv that has developed a test to distinguish real DNA samples from fake ones that it hopes to sell to forensics laboratories.

The planting of fabricated DNA evidence at a crime scene is only one implication of the findings. A potential invasion of personal privacy is another.

Using some of the same techniques, it may be possible to scavenge anyone’s DNA from a discarded drinking cup or cigarette butt and turn it into a saliva sample that could be submitted to a genetic testing company that measures ancestry or the risk of getting various diseases. Celebrities might have to fear “genetic paparazzi,” said Gail H. Javitt of the Genetics and Public Policy Center at Johns Hopkins University.

Tania Simoncelli, science adviser to the American Civil Liberties Union, said the findings were worrisome.

“DNA is a lot easier to plant at a crime scene than fingerprints,” she said. “We’re creating a criminal justice system that is increasingly relying on this technology.”

John M. Butler, leader of the human identity testing project at the National Institute of Standards and Technology, said he was “impressed at how well they were able to fabricate the fake DNA profiles.” However, he added, “I think your average criminal wouldn’t be able to do something like that.”

The scientists fabricated DNA samples two ways. One required a real, if tiny, DNA sample, perhaps from a strand of hair or drinking cup. They amplified the tiny sample into a large quantity of DNA using a standard technique called whole genome amplification.

Of course, a drinking cup or piece of hair might itself be left at a crime scene to frame someone, but blood or saliva may be more believable.

The authors of the paper took blood from a woman and centrifuged it to remove the white cells, which contain DNA. To the remaining red cells they added DNA that had been amplified from a man’s hair.

Since red cells do not contain DNA, all of the genetic material in the blood sample was from the man. The authors sent it to a leading American forensics laboratory, which analyzed it as if it were a normal sample of a man’s blood.

The other technique relied on DNA profiles, stored in law enforcement databases as a series of numbers and letters corresponding to variations at 13 spots in a person’s genome.

From a pooled sample of many people’s DNA, the scientists cloned tiny DNA snippets representing the common variants at each spot, creating a library of such snippets. To prepare a DNA sample matching any profile, they just mixed the proper snippets together. They said that a library of 425 different DNA snippets would be enough to cover every conceivable profile.

Nucleix’s test to tell if a sample has been fabricated relies on the fact that amplified DNA — which would be used in either deception — is not methylated, meaning it lacks certain molecules that are attached to the DNA at specific points, usually to inactivate genes.

depression

Ben Cousins reveals his battle with depression | Celebrity | News.com.au

* Cousins says he has battled depression
* "Couldn't leave the house"
* The Punch: Secret golf shame

BEN Cousins has revealed how he spiralled into depression after being told none of the 16 AFL clubs wanted him in the national draft.

The former Eagles star said he imprisoned himself in his house, refusing to speak to even his parents.

“I'm not a depressive person, but it was a state of depression,” Cousins told GQ Australia magazine.

“I had the life sucked out of me. I didn't feel like leaving the house.

“I slept a lot, I didn't talk to anyone. I wasn't on the phone to my parents or my mates. I just shut everything out.

“The process itself of getting me back to footy probably made me as vulnerable as I've ever been.

“That's the point that everyone has missed. The process itself was so counter-productive to what I was trying to achieve.

“I'd been given 12 months off, left to my own devices.

“The whole thing I wanted about getting back to playing footy was to give me the foundation that I needed. If I was in a perfect state of mind, I could have gone on and done anything, but I wasn't.”

Being overlooked in the November 29 draft was a wake-up call for Cousins.

Realising that the following pre-season draft was his last chance to extend his AFL career, he met AFL legend Kevin Sheedy to discuss the road back to football. He had talks with Richmond and convinced the club he was a chance worth taking.

Cousins, who starred in 238 games with West Coast, will today play his 250th, for the Tigers against the Swans at the MCG. He is scheduled to play against the Eagles on Friday, August 28.

“I wasn't born a great footballer. I've worked as hard as anyone I know my age,” he said.

Off the field, Cousins admits he continues to face his demons.

He says he watches what he drinks and is careful not to do anything that will put him on the path to destruction.

“I have to be careful with that sort of stuff (drinking),” he said. “I'm on a pretty strict regime.

“I can't afford to slip up, and enjoying the occasional drink is something I look forward to do. It's all in moderation.”

Cousins said drugs did not discriminate: “People from all walks of life can find themselves in trouble and strife, or mixed up with drugs. There's no right or wrong formula.”

Asked if his demons had left him, Cousins replied: “I'm not naive enough to think that I can just wash my hands of where I've come from and it's all in the past. The harsh reality is it's a struggle.”

Despite the tribulations of the past few years Cousins still showed a sense of humour during the interview and fashion shoot.

“Don't put me in an Elwood shirt. Every time I wear one of those I get arrested,” he quipped.
