IT Technology: YouTube to Allow Offline Viewing in App from November 2013

YouTube videos will soon be watchable without an internet connection, the video sharing site has revealed.

From November you'll be able to download videos to watch later using the YouTube app on mobile devices.

Other video apps like BBC iPlayer and 4OD already let you download videos to watch later, which auto-delete in time.

But on its Creators blog, YouTube says you'll be able to watch videos you've downloaded as long as your device goes online at least once every 48 hours.

The blog says: "This upcoming feature will allow people to add videos to their device to watch for a short period when an Internet connection is unavailable.

"So your fans' ability to enjoy your videos no longer has to be interrupted by something as commonplace as a morning commute."

IT Technology: Will Domain Name System (DNS) Affect Browsing Experience / Internet Slow?

Yes. DNS will definitely affect your browsing experience or cause the Internet slow.

The Domain Name System (DNS) is an hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates easily memorized domain names to the numerical IP addresses needed for the purpose of locating computer services and devices worldwide. By providing a worldwide, distributed keyword-based redirection service, the Domain Name System is an essential component of the functionality of the Internet.

Improper DNS selection will cause packet drop and high latency. Thus, this will affect your browsing experience and Internet slow. 

In Malaysia, if you are using TM service, you may want to use the following DNS so that you can browse the Internet smoothly.

<<Streamyx>>

202.188.1.5 or 202.188.0.133

<<Unifi>>

1.9.1.9

In order to configure the DNS in your Windows 7 computer, please check out the website at http://windows.microsoft.com/en-my/windows7/change-tcp-ip-settings

Google: YouTube Disco

YouTube's got millions of songs on its servers, and now, thanks to Vevo, a hefty slice of them are totally aboveboard. In Disco, YouTube's built an official, media-player-like front-end for all this music, with a Pandora-like discovery tool.

Disco's playlisting functionality is still a bit limited, and it's hard to tell what metrics are driving the music recommendation service, which isn't nearly as astute as Last.fm's or Pandora's. And since this is YouTube, there's a very real risk that whatever song you think has been added to your playlist could be the Alp1ne Techno-y0del remixXx of said song. But it's a minor tradeoff, because good god, YouTube has everything.
