Ubuntu 11.10 (Oneiric Ocelot)

Has been released yesterday, this edition includes the Ubuntu desktop, server, cloud, Kubuntu, Xubuntu, Lubuntu, Edubuntu, Mythbuntu, and Ubuntu Studio. Not too much difference with the previous edition 11.04 / Natty, just adding a few additional applications one of them: Deja DUP for backing up data.

Merger unity and compiz is a different side view of its predecessor, the login screen is also another. But as a whole can be spelled similar to the previous edition.

Because similar to the reply already installed, I just try and then delete it because of who got the laptop says "what is windows 8?"
Even more fun is waiting for 12.04 Ubuntu LTS (Precise pangolin) which is planned to release on April 26 next year (I think it's what Precise, was an anteater). 10.04 Maybe it could replace the LTS as well, because according to its developers this is a tough, durable and a little bug.

Good luck to those interested:

Ubuntu 11.04 Natty Narwhal Review


After waiting many months, the latest ubuntu release has been published a few weeks ago. What and how the performance of the Natty this.

Here's the latest test release ubuntu 11:04 uses several different hardware. Incidentally kompeter could borrow from friends and laptop to have someone (only intel, amd who do not have the love and loans)

1. Booting requires only 50-10 seconds (I3 processors or more)
booting requires 10-30 (under the dual cores, or netbook)

2. Desktop look a little different than previous releases, since it uses unity ubuntu 11:04.


glance for Apple users if somewhat similar, because the application is on the left desktop.

3. In the latest Ubuntu, there are some applications that change, which is very striking is that Open Office is no longer a default install of ubuntu. His replacement is the Libre Office, but its user exactly like other office applications like openoffice and microsoft office. Separate also is gimp, applications for the designer is also already there when the installation is not automatic, but we can still download through the application sypnatic or via terminal (apt-get install)



4. Browser Mozilla Firefox on ubuntu still, what a coincidence when released yesterday, also firefox has just launched its latest version. To support the performance of Ubuntu users. The latest version of Firefox has become the default browser on this Natty.



5. Natty is the latest breakthrough in cloud computing. If you want to store data in the cloud of ubuntu, ubuntu just use one application. This application is suitable for users who are super mobile.



So Ubuntu Natty review, we wait for the latest terobasan in the next Ubuntu release Oneiric Ocelot 11:10

PHP and Javascript Autocomplete Search

Starting from the case when the search data using a key word table in a MySQL database. Search results can be done in several ways, but the accuracy and convenience take precedence. What is desired is to enter one character per word, it will display the results of database queries associated with that character.

Suppose we look for the word or the name of someone in a database, simply by memasukkam word Y, then Y is related to the word will be displayed in a list table: Yoyo, Sandy, Bayu and others. Next we discussed the script. In this case the language of php and javascript. Search techniques using javascript function showHint.


<head>
<script type="text/javascript">
function showHint(str)
{
if (str.length==0)
{
document.getElementById("txtHint").innerHTML="";
return;
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","search1.php?q="+str,true);
xmlhttp.send();
}
</script>
</head>
<form>
Input Name : <input type="text" onkeyup="showHint(this.value)" size="20" />
</form>
<p><span id="txtHint"></span></p>

Save the script above with the name of search.php. Next create another php file with the name search1.php to invoke a MySQL database (database query) based on input from the file search.php

if (isset($_GET[q])) {
//load database from php
include ('../config/db_connect.php');
$q=$_GET[&quot;q&quot;];
$query = mysql_query(&quot;SELECT * FROM staff where name like '%$q%'&quot;);
?&gt;
&lt;table bgcolor=&quot;#000000&quot; cellspacing=&quot;1&quot; cellpadding=&quot;3&quot;&gt;
&lt;tr bgcolor=&quot;#DDDDDD&quot;&gt;
&lt;th&gt;ID&lt;/th&gt;
&lt;th&gt;Name&lt;/th&gt;
&lt;/tr&gt;
&lt;? while($row = mysql_fetch_object($query)): ?&gt;
&lt;tr bgcolor=&quot;#FFFFFF&quot;&gt;
&lt;td&gt;&lt;?=$row-&gt;ID?&gt;&lt;/a&gt;&lt;/td&gt;
&lt;td&gt;&lt;?=$row-&gt;name?&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;? endwhile; ?&gt;
&lt;/table&gt;
&lt;? }

So hopefully can help
