~ K Desktop Environment (KDE)

»K Desktop Environment (KDE)

General Overview
ξ KDE or the K Desktop Environment, is a network transparent contemporary desktop environment for UNIX workstations.
ξ KDE seeks to fulfill the need for an easy to use desktop for UNIX workstations,
ξ similar to desktop environments found on Macintosh and Microsoft Windows operating systems.
ξ The UNIX operating system is according to us the best available today.
ξ When it comes to stability, scalability and openness UNIX has no competition.
ξ In fact UNIX has been the undisputed choice of information technology professionals for many years.
ξ The lack of an easy to use contemporary desktop environment, however,
ξ has prevented UNIX from finding its way onto desktops of typical computer users in offices and homes.
ξ UNIX today dominates the server market and is the preferred computing platform for computing professionals and scientists alike.
ξ The Internet, a household name traces its heritage to UNIX.
ξ Inspite of such ubiquitous creations from the UNIX community,
ξ average computer users still expect it to be difficult to use and often stay away.
ξ This fact is particularly unfortunate since a number of implementations of UNIX,
ξ all of which are of exceptional quality and stability (Debian GNU/Linux, FreeBSD, NetBSD etc.) are freely available off the Internet.

KDE The Desktop Environment
ξ The KDE project aims to change all that.
ξ KDE now provides an easy to use contemporary desktop environment available for UNIX and compatible systems.
ξ Together with a free implementation of UNIX such as GNU/Linux, UNIX/KDE
ξ constitutes a completely free and open computing platform available to anyone free of charge.
ξ Source code is available for anyone to look at, learn from, modify and improve.
ξ Whilst there is always room for improvement, KDE today delivers a viable feature packed alternative to the more commonly found commercial operating systems/desktops combinations available.
ξ It is our hope and continued ambition that KDE will bring open, reliable, stable and monopoly-free computing
ξ enjoyed by scientists and computing professionals world-wide to the everyday user.

KDE The Application Development Framework
ξ KDE also brings to the forefront many innovations for application developers.
ξ An entire infrastructure has been designed and implemented to help programmers create robust and comprehensive applications in the most efficient manner,
ξ eliminating the complexity and tediousness of general UNIX application development.
ξ KDE recognizes the fact that a computing platform is only as good as the first class applications available to users.
ξ KDE's application framework, implements the latest advances in framework technology positioning it in direct competition with popular development frameworks like Microsoft's MFC/COM/ActiveX technology etc.
ξ KDE's innovative KParts compound document technology enables developers to quickly create first rate applications using cutting edge technology.

KDE The Office Application Suite
ξ Leveraging the KDE application development framework a great number of applications have been built for the K Desktop Environment.
ξ A selection of those applications is contained in the KDE base distribution.
ξ At this moment KDE is developing a complete office application suite based on KDE's innovative KParts technology.
ξ This modern day office suite offers spread-sheet applications, presentation creators, organizers, news clients and much more.
ξ KPresenter, a part of this application suite has already been successfully used for many presentations.

The Current KDE distribution
ξ KDE-Bindings: bindings for various programming languages (Python, Ruby, Perl, Java...)
ξ Web development applications and tools.
ξ

KDE Facts and Figures
ξ The KDE SVN source code repository holds currently over 4.0 million lines of code
ξ compare to The Linux kernel version 2.5.71 consists of about 3.7 million lines of code
ξ Over 1900 contributors help to develop KDE
ξ The translation team itself consists of about 300 individuals
ξ 11,014 SVN commits were made during May 2002
ξ KDE has more than 20 official website mirrors in over 14 countries
ξ KDE has more than 130 official download mirrors in over 40 countries

ξ delivers interoperability between applications and the Linux operating system
ξ all major distributions comply with the LSB
ξ many major application vendors, like MySQL, RealNetworks and SAP, are certifying
ξ offers a cost-effective way for application vendors to target multiple Linux distributions while building only one software package
ξ for end-users, the LSB and its mark of interoperability preserves choice
ξ by allowing them to select the applications and distributions they want while avoiding vendor lock-in
ξ LSB certification of distributions results in more applications being ported to Linux and
ξ ensures that distribution vendors are compatible with those applications
ξ LSB ensures Linux does not fragment
ξ If you are an end user looking for Linux distributions that support open standards, please see our list of LSB certified products
ξ If you are a developer looking to build portable Linux applications that will work on these distributions, please see the Linux Developer Network.

General
ξ an open source project to make programmers more productive
ξ expressive, concise, clean, and efficient
ξ its concurrency mechanisms make it easy to write programs
ξ that get the most out of multicore and networked machines,
ξ while its novel type system enables flexible and modular program construction
ξ compiles quickly to machine code yet has the convenience of garbage collection and
ξ the power of run-time reflection
ξ a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language

Concurrency, Channels, Threads
ξ Mutex: Lock and Unlock
ξ Select: lets a goroutine to wait on multiple operations
ξ Sender cal close the channel
ξ Buffered Channels
ξ Channels: Send (ch <- v) and Receive v := <-ch)
ξ Threads: go f(x,y,z) starts a new goroutine running f(x,y,z)
ξ Processes missing ?

Methods
Go does not have classes!
However, you can define methods on types.
A method is a function with a special receiver argument.
The receiver appears in its own argument list between the func keyword and the method name.
In this example, the Abs method has a receiver of type Vertex named v.
package main
import (
"fmt"
"math"
)
type Vertex struct {
X, Y float64
}
func (v Vertex) Abs() float64 {
return math.Sqrt(v.X*v.X + v.Y*v.Y)
}
func main() {
v := Vertex{3, 4}
fmt.Println(v.Abs())
}
Images
package main
import (
"fmt"
"image"
)
func main() {
m := image.NewRGBA(image.Rect(0, 0, 100, 100))
fmt.Println(m.Bounds())
fmt.Println(m.At(0, 0).RGBA())
}

Packages
ξ import (
"fmt"
"math/rand"
)
Exported names
In Go, a name is exported if it begins with a capital letter.
For example, Pizza is an exported name, as is Pi, which is exported from the math package.
When importing a package, you can refer only to its exported names.
Any "unexported" names are not accessible from outside the package.

Functions
A function can take zero or more arguments

Basic types
bool
string
int int8 int16 int32 int64
uint uint8 uint16 uint32 uint64 uintptr
byte // alias for uint8
rune // alias for int32
// represents a Unicode code point
float32 float64
complex64 complex128
