Carakan F.A.Q.

By Bruce Lawsonbrucelawson. Thursday, February 5, 2009 9:47:24 AM

What is Carakan?

Carakan is Opera's new JavaScript engine. It's still in development, but is already 2.5 times faster than our Opera 10 alpha engine (which itself is 30% faster on real websites than previous versions of Opera). Some aspects are between 5 and 50 times faster!

Why are we developing it?

Because we can! Opera has always been about speed, security and a small memory footprint, so we're constantly improving these aspects of the browser. Many of today's web applications depend heavily on JavaScript, and we're developing what will be the fastest ECMAscript engine on the market.

When will Carakan be available?

Soon. We've chosen to talk about it now as we're discussing it at the Web Directions North conference, but we're still combing its hair and straightening its tie before we're ready to let you see it.

How does it work?

It's a combination of brilliant coding and Scandinavian voodoo magic ("Snowdoo"). If you want more details about the brilliant coding, you can read all about register-based bytecode, automatic object classification and native code generation on the Opera Core Concerns Blog. We're sworn to secrecy about the Snowdoo. By a ~~Yeti~~ troll.

What does "Carakan" mean?

We thought about naming it "Unicorn-badger", "StackDonkey" or "Shouting Otter". But, we've chosen the name "Carakan" (pronounced "Jarakan"), which is the original alphabet from the Indonesian island of Java.

In other words, it's the purest Java Script. When you try it, you'll agree.

I love the Opera attitude, rock on devs, can't wait for Opera 10 (and a wii browser update... pretty please)

You'll have to ask Nintendo about Wii updates...

Why the name is "Carakan" not "Hanacaraka"??

I'm from Indonesia

Nicklas Westinkilsmo # Thursday, February 5, 2009 3:34:22 PM

Yes, we found out about the alternative name Hanacaraka after a few days (I'm not from Indonesia), but Carakan was the one that we got first, and Carakan sounds cooler to me.

Oh, please don't say so, because I'm already waiting for the best web developer tools on the market.

All thumbs for you guys, I really love the name since I'm a Javanese

Yeni Setiawansandalian # Friday, February 6, 2009 7:36:18 AM

FYI, 'carakan' in Indonesian and Javanese language is pronounced as 'carakan'. Some articles wrote 'carakan' as 'tjarakan' because 'tj' is an old way to write letter 'c' in Indonesian language (prior 1970s).

The letter 'c' in 'carakan' is pronounced like 'c' in 'charm'.

i imagined j can't be c

sandalian, thank you very much for the information about how it should be pronounced. The good thing is that is how we have been pronouncing it, so we do not have to change.

They said, almost 6 months ago, that it WAS between 2.5 and 50 times faster in SunSpider. In initial tests back then.

You might as well do what google and mozzerella did and write your own benchies to prove you're quickest. I have used Opera for over a decade because it feels the fastest and most responsive. It feels safe and sleek. Also it has a much smaller footprint in memory and on disk than any other browser (Save IE where most of it is in the OS). As I said I hope this is real world performance enhancing. Also Fx only comes out better in benchies not real world apps. Thats why all the Fx users thought chrome was fast when it was released - had they been using Opera they wouldn't have been so wowed.

lucideer # Monday, August 10, 2009 3:24:08 PM

Opera is still the fastest browser around, but the Sunspider benchmark, while obviously completely irrelevant in the "real" world, has become a de-facto statistic for blogs and those of influence to quote when comparing browsers. So targeting it is good for marketing, which is inevitably good for Opera users.

Good info to read. Wish you the best, Opera devs.

Nostradances # Thursday, January 21, 2010 2:10:56 PM

Monikers aside, Opera is still a "peoples browser". (more like the Swiss Army knife of the internet).
Been using it since it's creation, and now it's an addiction. One can imagine how hard it must be to avoid the pre-alpha release; but what a fine way to begin another Decade. Rock em' boys. Proper job....eh?

Carakan is already available in 10.50.

Hi

I was using this javascript http://lexi.ucoz.ru/userjs/show-ip.js to get IP on opera but it's not working on newer version of opera from v10.20 of Opera. It works in lower version than v10.20.

Any input will be helpful to get this script working.
