Tastefully tactile

Multitasking mojo

Ubuntu’s unique side stage places a phone and a tablet app on the same screen at the same time for amazing tablet productivity. True multitasking comes to the tablet.

Take calls in Skype while you work in a document, make notes on the side while you surf the web, tweet while you watch a movie.

Or use apps collaboratively – drag content from one app to another for a super-productive day. We’ve reinvented
the tablet as a bridge between phone and PC.

Safer sharing

Your Ubuntu tablet has multiple secure user accounts, and
a guest account. Perfect for families and friends, and ideal for the office, with secure multi-user logins that make using and sharing devices safe.

Data protection is world class with full disk encryption, and additional encryption for personal data, making Ubuntu perfect for sensitive environments and regulatory compliance in the medical, military, industrial and finance sectors.

Voice control in the HUD

The Ubuntu HUD makes complex application workflows simple on touch devices. This brings all the power of the
PC to your touch device. And with voice control, it’s as if
you had an extra set of hands – a truly personal assistant.

Take the tablet where it has never been before – image manipulation, movie editing, document management, CAD. With an interface that scales from the tablet to a PC, Ubuntu brings potent apps into focus on touch devices.

Savvy search

Ubuntu presents results from hundred of sources in
one gorgeous page, saving you the trouble of comparison shopping or hunting down the right provider. You’ll see information from your email and phone contacts alongside Facebook friends and followers on Twitter.

Looking for music? Ubuntu doesn’t just search the tunes
on your tablet, it also searches online, giving you a choice
of tracks you don’t yet own. It’s really one search to rule
them all.

Naturally neat home screen

The stylish home screen organises all your most important information, selected from hundreds of sources – online or
on board.

You can customise the screen and search for any kind of content. Watch what you want with a single touch – no need to worry which app to find it in.

Convergence that just clicks

Today’s tablets are as powerful as ultra-light laptops. Ubuntu uniquely supports a new category of convergence device – add a keyboard and mouse and your Ubuntu tablet becomes
a full PC and thin client, with access to Windows apps over standard protocols from Microsoft, Citrix, VMware and Wyse. That lets enterprise IT deploy a single, secure, portable corporate device for all kinds of applications.

Since it is pure Ubuntu, the tablet can be managed via Landscape, giving enterprises complete control over the users, apps, updated and access using the same tool they
use for Ubuntu servers and desktops today.

동기적으로 요청을 처리하는 아파치 웹서버와 달리 비동기적으로 요청을 처리하는 NGINX의 Non Blocking Event-driven 구조.

* 설치파일 내려받기

  http://nginx.org/en/download.html

  http://wiki.nginx.org/Install

* 설치  

압축해제폴더에 들어가서  ./configure 를 실행한다.

./configure -prefix 옵션을 사용하면 설치될 위칠르 지정할 수 있다.

디폴트는 /usr/local/nginx/ 에 설치된다. 

NGINX를 설치할때 필요한 라이브러리는 pcre,openssl, zlib 등이 있는데 yum을 이용해서 직접 설치 가능하다. 

설치가 됐다면 /설치폴더/sbin/nginx 명령어로 실행할 수 있다. 

실행 : /설치폴더/sbin/nginx

중지 : /설치폴더/sbin/nginx ?s stop

재실행 : /설치폴더/sbin/nginx ?s reload

* Configuration

서버 설정 파일 : /opt/nginx/conf/nginx.conf 

설정 파일을 따로 만들고 싶다면  /설치폴더/sbin/nginx ?c 설정파일명

설정 파일 구성은 Main, Event, http, server, location 블록의 계층구조이다.

nginx는 러시아인인 igor Sysoev가 만들었다.

웹(http)서버, reverse proxy, IMAP/POP3 서버.

C10K problem 을 해결하기 위해 기존의 아파치 방식처럼 사용하는 것이 아니라,

Event-driven(Asynchronus) 구조를 사용한다.  이와 유사하게 Node.js도 Event-driven 구조를 사용한다.

EDA(Event-driven Architecture)는 아파치보다 훨씬 적은 스레드개수로 많은 클라어언트를 처리할 수 있다.
