Go: Google’s new open source programming language

IncreaseDecrease

Go mascotGoogle never seems to just be satisfied with the status quo, and when they run out of fields to compete in they create their own! Google’s new “Go” programming language is one of their newest ventures, a language which is an amalgamation of Python and C++.



The Go language, in development since September 2007, has been unveiled by Google along with the release of a free and open source compiler. In fact, Google has released both a stand-along compiler implementation with cryptic names such as 6g (amd64 compiler), 8g (x86 compiler), and 5g (ARM compiler) and one which is a front-end for GCC (gccgo).


Born out of frustration with existing system languages, Go attempts to bring something new to the table, and mix the ease of dynamically typed and interpreted languages with the efficiency of compiled languages.


So why make a new programming language?



Google believes that the current languages have run their course. The prominent languages in use today (C/C++, Java, C#) are all based around a similar syntax, and updating and adding new features in these language consists of piling on libraries, with little or no upgrade to the core of the language itself. What Google intends to do requires more than just the addition of a new library.

-------------------------------------


Hello World in Go

package main

import "fmt"

func main() {
fmt.Printf("Hello, ??n")
}

---------------------------------------


The landscape of computing has changed a lot since C, and as Google notes “Computers are enormously quicker but software development is not faster.” Languages have had to morph quite a bit to take on support concepts such as parallel processing, and garbage collection.



Go, on the other hand has been designed by Google from the ground up as “a concurrent, garbage-collected language with fast compilation”.



In order to not alienate the majority of developers though, its syntax is quite similar to C, and would not take much time for a developer to catch on to.



Go has accomplished some impressive feats. The language is designed to compile fast and Go can compile a “large" program in a few seconds on a single computer. It is designed to simplify the creation of application which can better utilize today’s multi-core processors. The language supports concurrent execution and communication between concurrent processes natively, and is fully-garbage collected.



Goroutines allowed are Google’s answer to threading in Go, and any function call which is preceded by the go statement runs in a different goroutine concurrently. A feature called channels allows for easy communication and synchronization between such routines.



Unlike other object oriented languages, Go has a much “simplified” type structure, which disallows sub-classing! Go offers a different flavour of object oriented programming using interfaces, which Google believes will simplify use.



By using interfaces, explicit type hierarchies need not be defined, instead, a type will satisfy all interfaces which are subsets of its methods. The relationships between types and interfaces need not be defined explicity! This can have some interesting implications as people can add interfaces to connect unrelated types even later in the development of an application.



Go seems inspired by Python as well. Python has been one of Google’s favoured languages and was the sole language supported on Google’s AppEngine when it launched. Like Python, Go supports “slices”, which allow you to refer to parts of arrays using a simple syntax. Thus for an array “a” with 100 elements, a[23,42] will result in an array with elements 23 through 42 of a. Go also tracks the length of arrays internally, further simplifying array usage. Additionally, Maps in Go allow you to create “arrays” with custom index types, and are a native feature of the language.



One consistent point in the features of Go is that it is better to have one excellent implementation of commonly used features such as garbage collection, strings, maps etc. rather than have them rethought and re-implemented in each program.



As nearly all Google products, Go is “beta” and not yet suitable for production use. By releasing it early Google hopes to garner a community around it and hopes that enough people will be interested in it to justify continued development.



Get out there and grab Go now! Like any Google product it has the capacity to become standard for the next generation.

How to Hide the drives(c:,d:,e:,a:...etc)
This is a great trick you can play on your friends. To disable the display of local or networked drives when you click My Computer.




1.Go to start->run.Type regedit.Now go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Now in the right pane create a new DWORD item and name it NoDrives(it is case sensitive). Now modify it's value and set it to 3FFFFFF (Hexadecimal) .Now restart your computer. So, now when you click on My Computer, no drives will be shown(all gone...). To enable display of drives in My Computer, simply delete this DWORD item that you created.Again restart your computer.You can now see all the drives again. Magic........lol....

Different ways to shutdown ur PC

Different ways to shutdown ur pc

There are so many different ways to turn off your Windows XP computer, let's look at some of them:


1. The standard approach - click the Start Button with your mouse, then select the Turn Off menu and finally click the Turn Off icon on the Turn Off computer dialog. blink.gif

2. Press Ctrl+Esc key or the Win key and press u two times - the fastest approach.

3. Get the Shutdown utility from Download.com - it add the shut down shortcuts for you. Else create them yourself using approach 4.

4. Create a shutdown shortcut on your desktop. Right click on the desktop, choose New Shortcut and type shutdown -s -t 00 in the area where you are asked to specify the location of the program file. Now you can just double click this icon to turn off the computer. The best location would be your quick launch bar.

5. Press the Win key + R key to open the run window. Type shutdown -s -t 00. [s means shutdown while t means the duration after which you want to initiate the shutdown process].

If some open processes or application won't let you turn off, append a -f switch to force a shut down by closing all active processes.



6. Win+M to minimize all windows and then Alt+F4 to bring the Turn Off computer dialog.

7. Open Windows Task manager (by right clicking the Windows Task bar or Alt+Ctrl+Del) and choose Shut down from the menu. Useful when the Windows are not responding.


8. open task manager--->click on shutdown--->hold the ctrl key and click on Turn off::::::: pc will be turned off in 3 secs.. fastest method other than hard shutdown
