Asynchronous JavaScript and XMLHTTP, or abbreviated AJaX, is a web-based programming technique for creating interactive web applications. The goal is to move most of the interactions on the web surfer's computer, to exchange data with the server behind the scenes, so that the web page does not have to be re-read in its entirety every time a user changes. This will increase interactivity, speed, and usability. Ajax is a combination of:

DOMs are accessed with client side scripting language, such as VBScript and ECMAScript implementations such as JavaScript and JScript, to dynamically display and interact with displayed information
XMLHTTP objects from Microsoft or XMLHttpRequest are more commonly implemented in some browsers. This object is useful as an asynchronous data exchange vehicle with web server. In some AJAX frameworks, the IFrame HTML element is preferred over XMLHTTP or XMLHttpRequest to exchange data with the web server.
XML is generally used as a transfer document, although other formats are also possible, such as HTML, plain text. XML is recommended in the use of AJaX techniques because of its easy access handling by using DOM
JSON can be an alternative choice as a transfer document, considering JSON is JavaScript itself so that handling is easier
Like DHTML, LAMP, or SPA, Ajax is not a specific technology, but rather a combination of technologies used together. In fact, Ajax-based derivative / composite technologies, such as AFLAX, are beginning to emerge.

Git is a version control system used by developers to develop software together. The main function of git is to set the version of the source code of your program by giving the line mark and which code is added or replaced.
Git is actually easier for programmers to know the source code changes than to create new files such as Program.java, ProgramRevisi.java, ProgramRevisi2.java, ProgramFix.java. In addition, with git we do not have to worry about the code that we do clashing, because every developer can create branches as workspace.Features no less cool again, in git we can comment on the source code that has been added / modified, this makes it easy for developers another to know what constraints experienced by other developers.
To know how to use git, here are the basic git commands:
Git init: to create a repository on a local file that will have a .git folder
Git status: to know the status of the local repository
Git add: add a new file to the selected repository
Git commit: to save changes made, but no changes to the remote repository.
Git push: to send the file changes after the commit to the remote repository.
Git branch: view all branches in the repository
Git checkout: switches the active branch with the selected branch
GIt merge: to merge the active branch and branch selected
Git clone: ​​make a copy of the local repository
Examples of version control system software are github, bitbucket, snowy evening, and much more. If you as a developer do not know this git feature, then you must try and use it. Because of the many benefits to be gained with this git.

Subversion, also known as svn or SVN, is an open source version control software that can manage software development processes performed by a separate group of programmers into traces and orderly. Subversion was created by CollabNet which holds the trademark "Subversion" and is still preserving this project. The latest version of Subversion is 1.4.4 released on June 8, 2007. Subversion is available in Linux, Windows, FreeBSD, OpenBSD, Solaris, Mac OS X and OS / 400 versions.

Subversion is specifically designed as a modern replacement for CVS. The use of Subversion as an alternative to CVS as a slow version controller began to widen. Projects that use Subversion include Apache Software Foundation, KDE, GNOME, GCC, Python, Samba, Mono, MediaWiki, etc. SourceForge.net has also provided Subversion hosting for open source projects.

What is Repository?
Repository is a storage place hundreds of applications or programs that have been arranged in such a way and available to be accessible via the internet. However, the repository is not only accessible via the internet but we can also use alternative repository through distribution on other media such as DVD which is of course very helpful for us who do not have a fast internet connection.

When updating the Ubuntu repository, we download the repository from the existing server address in /etc/apt/sources.list and the default server address that is located on the sources.list is an external server address, such as archive.ubuntu.com, security.ubuntu .com.Server repository here serves as a server that provides a collection of software packages or collection of applications from Linux distros that can be accessed via the internet.

The steps taken are as follows:

1. Open the Dashboard, then select Terminal

2. Once the terminal window opens, type "$ sudo su"

3. Enter your password

4. Edit the repository by typing "# gedit /etc/apt/sources.list"

5. Delete all existing repository server addresses in the text editor window

6. Open a web browser, for example Firefox, and open the server address repository that provides various software or applications, eg http://singo.ub.ac.id

7. Find the version of Linux that you use, then Copy and Paste the repository on this website Singo.ub.ac.id special Malang area want to quickly download the file repositorynya, according to your version of Linux.

Photoshop is a graphical application for creating and editing images. photoshop is already very popular among the community, because of its many features and easy to use. as a beginner photoshop, you must know how to create a new document in photoshop, here's a basic photoshop to start editing images.

The term new document must have often we hear. where each job definitely requires the stage of creating new files, new worksheets. at the stage of creating a new document, there are several settings that must be met, ranging from paper size, image resolution, and color mode. when the setting will determine the size of our file after it has finished working. the larger the size and resolution the greater the capacity of the image is created.

How to Create a New Document In Photoshop

In photoshop, it's easy to create a new document. the most important thing in this tutorial is to understand the function of the existing settings items. for those who want to continue the lesson photoshop, to the next stage please de list of budding photoshop tutorial.

Step 1

Open Photoshop App. Then Go to File Menu - New. after that will appear settings to create a new worksheet (new document). how fast, press CTRL N.

>Name = the name of our document.
>Preset = Option for paper size already set by photoshop. in it already has paper size A4, A3, Letter and      so on. if you want to set its own size, then select Custom.
>Width (width) and Heigth (height) = is the size of the worksheet calculated by the formula Panjag x Width.     beside it is the unit of measure, my friend can use other than pixels, like centimeters, millimeters, inchi and       so on.
>Resolution is the image quality that will be generated. the default is 300 DPI (dot per inch). the higher the      resolution value the smoother the resulting image will be. more details read graphic design terms.
>Color Mode is the color setting that will be used. the most commonly used is RGB. but if you create a          design for the print should use CMYK because all types of print using CMYK settings.
>Background Content = The color of the worksheet. there are three options: White (white), Black (black)      and Transparent (transparent).
>Click Ok to start the design work.

Step 2

The appearance when you have created a new document is as below. my friend brought directly to workspace photoshop. it's time to make a design.

More or less like that is how to create a new document in photoshop. the point is, my friend must know the size of the design, to where the quality to be produced, trakhir customize the ability of the computer. because the bigger the image size and the resolution the more it will consume computer RAM. can-can even slow and Error.

Using Photoshop, surely we can not escape the use of the layer, because every image that opens in photoshop will be organized into a layer. for my friend who wants to learn how to edit photos, then multiply the exercise using the layer. in the Layer panel is still a lot of stored settings that can be made experimental materials in your practice.
note:
>Occasionally learn Manipulation of photoshop tutorials that are widely circulated on the internet. but do not take too much headache first, which is important follow the steps - steps to complete. it is intended to refresh our basic knowledge through more Difficult levels.
>Create keywords in your practice. For example, Tricks using Layer, Tips using Color balance on photos and others. this is meant to be more specific training buddy.
>Many do Experiments. by self learning without any tutorial resources. combine some tools that have been studied. will surely find a trick. I'm sure of that. "It's based on my experience".

>When learning to edit photoshop from other people's tutorial material, be sure to understand the process, not see the result. many people can manipulate in Photoshop, but still hope from the material, because he does not understand what the function of all the techniques in the manufacturing process.

IMAGINATION OF BEAUTY

In the world of Editing, imagination determines the outcome to be achieved. because we can see a small picture of our results through this unlimited fantasy. according to my experience, when I was just learning to edit photos with photoshop I always confusion to make a photo becomes more interesting than ever. because of my lack of knowledge about beauty.

With so many times I read various theories then I conclude that. our brains must often receive an information of beauty. because it has a beautiful structure pembentuknya. from that structure I learned to shape the beauty in my imagination. whether it be color, shape or other.
Example. :
>The rose is one of the flowers with the beauty that has captivated the whole human eye in the world. Should you ask in yourself, what makes that beauty ?? if in view rose flowers have a red color, with the shape of the petals curved - curved so. in added typical fragrance. take this point into your brain. and make it into the formula that makes up the beauty. when my friend already has many formulas of beauty, I am sure any bad object that is in front of our eyes, would be beautiful in our imagination

Understanding and Function of UTP Cable
To understand UTP cable function then we better discuss first about what is the definition of UTP cable or stands Unshielded twisted-pair. UTP cable is a type of cable made of copper conductor, has a plastic insulation and is encased by an insulating material capable of protecting from fire and physical damage.
UTP cable consists of four pairs of interlocking cable cores each of which has different color codes. UTP cable has no protection from electromagnetic interference, but this type of cable is widely used because of the relatively cheap price and its function that is in accordance with the expected standards.

UTP cable function is used as a LAN network cable (Local Area Network) on a computer network system, and usually UTP cable has an impedance of approximately 100 ohm, and is divided into several categories based on its ability as a conductor of data.
In everyday use, UTP cable is very well used as a computer network cable for example in the use of office space or in a company's network system. Regarding some of the weaknesses and shortcomings of UTP cables that are not resistant to electromagnetic fields and damage to hard object collisions, can still be overcome by installing an outer protector such as a plastic pipe.
Definition of LAN Cable
1) LAN is composed of some basic elements that include components
hardware and software. Hardware components include: Personal
Computer (PC), Network Interface Card (NIC) and Cable. While
software components include: Network Operating System, Network
Driver Adapters and Network Protocols.

2) There are three types of cables that are known in general, namely:
· Coaxial cable
· Fiber Optics
· Twisted pair (UTP unshielded twisted pair and STP shielded twisted
pair)

2) Known two types of coaxial cable, ie thick coaxial cable (has
large diameter) and thin coaxial cable (has diameter
smaller).

3) There are 2 types of cable connection for computer network, that is
straight cable and crossover cable where each has
different functions of ynag. Straight cable is used to connect
client to HUB / Router, while crossover cable is used for
connect the client to the client or in a particular case is used
to connect HUB to HUB.
Here's the latest 6 will give you a glimpse of the experience of network cabling when it used to practice in the computer lab ..
hopefully all readers who have forgotten or have doubts how to make it can remember it again .. ..
the following stages or HOW TO MAKE LAN CABLE in straight and cross

First prepare first the necessary tools:

UTP cable does not pass 100 meters long

UTP cable

Jack RJ-45

RJ-45

Crimping Tool / Tang Clamp

crimping tool / clamp tang

If all the above equipment we need is available then we can already start to MAKE LAN CABLE.
cable lan or network cable has 2 types:

1. STRAIGHT LAN CABLE
Straight LAN cable is a cable that has the same way of mounting between the tip of one with the other end. Straight cable is commonly used to connect 2 different types of devices.
How to make :

Peel the outside of the UTP cable about 2cm until the inside cable looks like in the picture above UTP cable.
Separate the cables inside and straighten. Sort and trim based on Orange White, Orange, White Green, Blue, White Blue, Green, Brown White, and Brown. Then cut the ends so that they are flat on each other.
Insert the cables into the Jack RJ-45 pins in the following order:

lan straight sequence
2. LAN CROSS CABLE
LAN Cross cable is a cable that has a way of installation that has a different arrangement between one end with the other end.

A cross cable is commonly used to connect 2 devices of the same type directly. such as connecting the first computer with computer 2 directly without using another intermediary.

How to make :

Do exactly the same with a straight LAN cable for the first tip.
For the other end change the arrangement of cables inside RJ-45 to: White Green, Green, Orange Orange, Blue, White Blue, Orange, White Brown, Chocolate
When finished in the clamp with clamp pliers, the cable is ready for use.

Here is the final image of the ends of the cross cable:
lan cross sequence

Such are the ways and explanations about making lan cables for this article.
hopefully can be useful for all readers.

LAN LAN CABLE OPERATION SYSTEM
Ian cable is an Ethernet transmission medium that connects network devices in your computer network. It is very useful if you know better about the lan cable before you make network design. Good network cable design, is a supporting element that makes your computer network will be easy to maintain and reliable. So the lan cable is very useful once in the reality of the network. The following are the 2 types of lan cables commonly used in LAN networks.
