Internet, on the one side is the technology which is very useful for us. With the Internet, we can find information and news with a very easy and fast. Just a few clicks, we can find a variety of information from various parts of the world that will presented at our computer screen in a matter of seconds.

In addition, we can also utilize the Internet to conduct banking transactions through Internet Banking service with comfortable without having tired of waiting in line at the bank or ATM machine. Internet is also able to connect us with friends or acquaintances we even distance apart, and even so many years apart.

However, behind all the Internet also has the potential threats that we must not take for granted. It is worth our attention to some tips given by ENISA (European Network and Information Security Agency) in his article entitled “Internet Safety Tips for Parents and Guardians” :

1. Communicate with your child about his / her Internet experience. Discuss the importance of Internet safety and teach the basics

Parents should contribute actively to explain to their children how to access the Internet securely. For parents who have high educational backgrounds and often use the Internet may find it easier to communicate with children compared with parents of its Internet knowledge is still lacking.

In this case it should parents have to learn the Internet is also in order not to lose with their children. Minimum parents need to know the basics of the Internet.

2. Set house Internet and mobile phone rules

Sitemap has a very important role in accelerating the process of the index by search engines. Related to that, in this article I want to review the topics that are also associated with a sitemap that is about the ping.

What is pinging?

Ping is a method to notify the search engine updates that have occurred on our blog.

Complete definition according to Wikipedia is:

In blogging, ping is an XML-RPC-based push mechanism by Which a weblog notifies a server That its content has been updated. An XML-RPC signal is sent to one or more “ping servers” Which Can then generate a list of blogs That have new material.

With the expected ping the search engines crawlers will soon visit our blog to index a new page in the blog. How to ping the search engines? Fairly easy way is by sending an HTTP request to the server from the search engines. The following ping addresses from several popular search engines:

You have an account on Facebook? If yes, of course you know that Facebook has an application similar to the blog, called Facebook Notes. With Facebook Notes, we can make notes on Facebook just like creating a post on the blog, and share them with our friends. Even if we already have a blog before, we can also import existing articles on the blog to Facebook.

The difference with blogs, Facebook notes are only accessible by visitors who already have an account on Facebook. In addition, we also can make its own arrangements in each record, whether published or not willing.

Here’s how to import articles from blogs to Facebook. First, select the icon entry in the list contained the Applications menu at the footer of the Facebook application. If a list of the Applications menu is missing, maybe you need to make arrangements beforehand.

On the Settings entry, click the Import menu to import your blog from blog articles.

Enter the URL of the blog in the pages of Foreign Import a Blog Importing and click the Start button.

Can you imagine how troublesome if we have to upload a file or document which is quite a lot to the web server. If we just rely on the application we’ve ever uploaded, must be very tiring and boring. Why is that? Yes, of course, because the application is only able to send one document in a single upload.

Therefore we need to modify the application to be able to send many files in one upload. Sure makes our job easier if we can upload many documents at once with just one click. In addition to more practical, this approach can also save the bandwidth of the Internet.

We can create a web application to upload multiple files in a way to save the information which we will upload the file in an array variable. The technique is relatively easy by adding brackets or [] behind the name tag on a form input that we make.

For example we can see in the sample code below.

action=”upload.php” <form method=”POST” enctype=”multipart/form-data”>
<input <p> name=”userfile[]” type=”file” /> </ p>
<input <p> name=”userfile[]” type=”file” /> </ p>
<p> value=”Upload” /> <input type=”submit” name=”submit”
</ Form>

When we click the Upload button, automatically all the files that we send will be stored in a variable array $ _FILES . Almost the same as the previous application was not it? The difference only lies in the input tag name only.

So now how do I handle data at the server side? Not much different from the previous application. Only, in this case the data that is sent not just one but several pieces of data (in this example there are two) are all stored in the variable $ _FILES .

In addition to the NextGen Gallery, we can also install a photo album in WordPress by utilizing our existing collection of photos on Flickr. This mode is more interesting because we no longer need a large space on the web server to store the photos.

Flickr Gallery is one of the WordPress plugin that we can use for this purpose. After we install and activate the plugin, click the Settings menu – Flickr Gallery Flickr API and then enter the User ID that we have in the column that has been available.

If the Flickr API and User ID that you enter is valid, at the bottom of the Settings page you will see this collection of photos that we have on Flickr. The next step, we just insert a specific code (shortcode) to display images on the page Post / Page.

Examples are as follows:
