The first and most obvious thing you will need to have your own server is an Internet connection. This connection can be dedicated to the server or shared with other computers, however, there are a few things to consider when choosing an service plan for a server. The first is upstream speed. Because most Internet users download far more data than they upload to the Internet, most service plans have a drastically higher downstream speed than upstream speed. The amount needed will vary according to the type of server you wish to run. So it’s important to estimate your needs and, when shopping for service, read the fine print to ensure that the plan provides enough upstream bandwidth.
Static Internet Protocol (IP) Address
The other important consideration when shopping for service is how IP addresses are assigned. An IP address is a number that is used to identify a computer on the Internet. With most service plans, this number will often change each time a computer reconnects. This is called a Dynamic IP address. This works fine, unless you have a server that intends to have its own domain name. Domain names (such as www.ehow.com) must be looked up using a special service to translate them into a server’s IP address. However, if a server’s IP address is constantly changing, this can create problems when users try to look up your server by domain name. Therefore, it is important to purchase a Internet service plan that promises you a Static IP, one that does not change.
Dedicated Computer
While it’s quite possible to use a server computer as a desktop computer also, there are a number of reasons why this is not advisable. The biggest reason is security: servers are visible to the Internet in a way that a well-maintained desktop system usually isn’t. Running server software is essentially opening a window into a computer that is usually kept closed and locked.
Server Software
You will need software to serve the content you wish to serve. What you choose will depend on your own needs. If you wish to serve a website, the open source and very widely used program Apache is the most common. If you wish to serve an online game, you will need server software from the game’s publishers.
Security Software
Finally, and sadly, you will need security software. While you ought to have security software such as antivirus protection and a firewall running on every machine in your network, this becomes doubly important with a server. As mentioned above: running server software opens gateways into your computer that are normally left closed, and that makes it easier and more likely that your computer will be targeted by malicious hackers.

How to Add a Site to Coda (FTP/SFTP)In Feburary 2016 09,
In Feburary 2016 09,
Open Coda on your Mac. At the top of the application are a few icons showing various options. Click the Sites icon.
Look at the bottom of the window for the Add Site button. Click this button. A window comes up that allows you to add all the server credentials for the site you want to add to Coda.
Fill in the text boxes with the necessary information. Beside Nickname, type the name you will use to identify the site. Add the homepage address next to Root URL to grab a screenshot of the site to display. Under Connecting, add the server address, user name and password. You can change the transfer protocols from FTP to SFTP in the Protocol drop-down menu if you wish to use the secure transfer protocol instead. Adjust any other settings as needed.
Click the 'Save' button to save all your needed settings. If your settings are correct, you will see a screenshot in the Coda app. Click it to connect to your server. If you didn't input the settings correct, Coda will let you know and you will have the opportunity to edit the settings.

Easy Ways of Adding Subtracting IntegersIn Feburary 2016 01,
In Feburary 2016 01,
The sum of two negative integers is found in the same manner as the addition of two positive integers. The two values are summed and retain the sign of the added values. For example, the sum of -2 + -3 is -5, while the sum of 2 + 3 is 5.
Addition of a Positive and Negative Integer
The sum of a positive and negative integer can easily be found by following three simple steps: identify the integer with the largest absolute value (a number's value irrespective of sign), subtract the integer with the smaller absolute value from the integer with the larger absolute value and retain the sign of the larger. For example, the sum of -5 and +3 is -2. The absolute value of the two integers is 5 and 3, respectively, so -5 has the largest absolute value. The difference between the number with the larger absolute value and the number with the smaller absolute value (5 - 3) is 2. Applying the sign of the integer with the larger absolute value then gives a final answer of -2.
Subtraction of Negative Integers
The procedure for finding the difference of two integers is the same for both two positive and two negative integers. Change the subtraction sign to an addition sign, reverse the sign of the integer being subtracted and then follow the addition rules for integers. For example, -3 - 5 is rewritten as -3 + -5. The values are then summed, and the sign of the two integers is retained, resulting in a difference of -8. Now take the opposite case. You would rewrite 3 - 5 as 3 + -5 and then use the directions in Section 2, subtracting the integer with the smaller absolute value from the integer with the larger absolute value (5 - 3 = 2) and then applying the sign of the integer with the larger absolute value, getting -2.
Follow the Rules
Subtraction of negative integers is the most difficult of the procedures to perform. However, if you follow the rules for addition in Sections 2 and 3, the process becomes very easy. Begin by transforming the problem from one of subtraction to one of addition as in Section 3. That is, transform the minus sign into a plus and then reverse the sign on the number being subtracted. For example, rewrite -3 - (-5) as -3 + (+5) or -3 + 5. Subtract the integer with the smaller absolute value from the integer with the larger absolute value (5 - 3 = 2) and then apply the sign of the integer with the larger absolute value, getting 2.
