The simplest thing I tried and that solved my problem by the following way:

if I one to search 1 space:

SELECT * FROM tbl_name where str_field LIKE '% %'

if I one to search 2 space:

SELECT * FROM tbl_name where str_field LIKE '% %% %'

if I one to search 3 space:

SELECT * FROM tbl_name where str_field LIKE '% %% %% %'

The writer Adam Griffiths nicely describes details of this framework. Beside codeigniter framework, the writer also mentioned how to add external libraries like facebook,twitter, memcache to develop web application using codeigniter framework.

Amazon opted to build their own content delivery network (CDN) while Rackspace chose to partner with Limelight Networks, a leading, global CDN provider.  Limelight serves some of the largest media customers in the world (including Disney, MSNBC, NetFlix, Microsoft Xbox, and Amazon Video on Demand) and has an extensive world-wide network. For a brief comparison read this article.

If you have wordpress powered sites and want to use CDN either amazon s3 or rackspace cloud files, then you could easily integrate them using the following plugins.

1. CDN Tools for Rackspace Cloud Files
2. W3 Total Cache for caching and using amazon cdn

I’m using CDN Tools and its an excellent plugin. Just install the plugin and configure it by providing your rackspace cloud username and api key. Then by clicking Load Attachment your existing static contents will be uploaded in rackspace and on the fly the static content will load from cdn. You can also disable the feature when you want. And another good option of this plugin is that it uploads files side by side. So when you upload your files in wordpress this plugin copy the file in rackspace. So if for any case you don’t want to continue with rackspace, you can just disable the plugin and the static content will load from your server again.

If you want to integrate Amazon S3 in your site then you can use  W3 Total Cache. This is also a nice plugin but it doesn’t support Rackspace yet. You will get brief information by visiting the plugin page.

There is a function in php named array_unique($array); that removes duplicate elements from array. So in php I could easily use

    $arr = array('a', 'b', 'a', 'c', 'd', 'b');
    $arr = array_unique($arr); //removes duplicate entries

But there is no such type of built in function in actionscript 3 for array. So I created my own function and used it

function removeDuplicate(arr:Array) : void{
    var i:int;
    var j: int;
    for (i = 0; i < arr.length - 1; i++){
        for (j = i + 1; j < arr.length; j++){
            if (arr[i] === arr[j]){
                arr.splice(j, 1);
            }
        }
    }
}

Now just call the function and pass an array

var arr:Array = new Array("a", "b", "a", "c", "d", "b");
removeDuplicate(arr);

splice(startIndex:int, deleteCount:uint); method removes elements from an array. So using 2 simple loops I solved my problem. But as my arrays are short 20 elements max so I don’t need to optimize this function.

In 2008, first time I bought shared hosting account and domain from GoDaddy.com using my debit card. I’ve still one of my site is hosted there as I bought for 3 years hosting.  I don’t like their control panel to mange my host. It looks slow for me.  And regarding their server, if you host facebook application that has low traffic sometimes you’ll see timeout. So think what happen if you have moderate level traffic application. I think their server is sharing many accounts and thus response time is slow most of the time. I don’t recommend Godaddy for any purpose.

In 2009, I bought another shared hosting and domain from umbrahosting.com. Their service and support was awesome at the first time. Their server is very good as they share few accounts per server. I’ve no complain to their server, if you host your facebook application you’ll get very good server response time. You can also use their shared hosting for moderate level traffic for your site. But some months ago I found downtime of my site in their server. When I sent ticket to them they solved it after 8 hours. So I’m very much angry about their support. Just imagine your high priority ticket is not solved within 8 hours. Though they have a chat system but most of the time that is unavailable. Another interesting thing is that, I ordered a managed VPS with CPanel + WHM from them and they took more than 24 hours to setup fully. And when I going to test I found php is not working. I canceled that VPS after 2 days and later I canceled my shared hosting from them. If you need less support but cheap and good performance shared hosting then definitely go with them.

In middle of 2009, I bought a server from Rackspace Cloud, and it was awesome. If you have a web site or applications that are getting high traffic, you should definitely go with them. You can buy one, two… many servers from them as you want. When you don’t need a server you can just delete that from your account and you’ve to pay for what you have used.

In the late 2009, I bought an unmanaged VPS (virtual private hosting) from hostlatch.net. Price is cheap as I bought in Christmas offer.  I am using free webmin+virtualmin to manage that hosting myself.  Never buy from this company. Their server performance is very bad. I’m totally disappointed about their server performance and I lost some regular users from my facebook application.

In 2010, I first bought shared hosting from hostmonster.com and I’m quiet unhappy about their server performance and so why I moved to hostgator.com shared hosting. I’m using hostgator.com’s business plan for shared hosting that has a free dedicated IP and SSL. I found hostgator’s server performance is very good. Regarding support hostmonster and hostgator have serious in their supports. You can chat any time with them. They response fast and I appreciate their supports.

If you want to store your static files in CDN, then you should select rackspace cloud files over Amazon S3. Amazon s3 is slower than rackspace cloud files. I’m currently using rackspace cloud files and I recommend it to others.

To register domain, I recommend name.com. Their service is awesome and their DNS servers update quickly. They also provides free private whois and google apps including system.

Before you buy hosting from any company you should check reviews from webhostingtalk.com . And also never forget to see TOS of a company before proceed. Some companies like hostgator, hostmonster, umbrahosting accept 30 days unconditional money back guarantee and prorated refund when cancel account after 30 days. So you’ve no chance to loose your money if you don’t like their service.

So if you want to get alert message when your site is down you could use third party service like site24x7, siteuptime , 100pulse

All of them has free services and paid services. Personally I use site24x7 . Here You could set 2 urls and http port check in 60 min interval as a free service. You can pay 1$/month for 1 Url to check between 1 min to 60 min. They will send email to you if your site is down. You can also purchase SMS package so that they can also send sms message as alert.

So checkout these sites and use which site suits best to you.

Actually this is not a big or complex post. I am a part time ActionScript 3.0 developer and recently in my company i2we, inc. I developed a customized jobs search widget for them. Where one of the criteria was when we include flash object in html, we can provide external parameter. Based on the parameter the flash widget customize its result.

So in this post, I will show how you can pass parameter from html and get them in your flash object. Please keep in mind that my code is based on ActionScript 3.0

Look at the html code

<object classid="clsid:xxxxxxxxxxxxxx" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=10,0,0,0" width="250" height="370" id="widget" align="middle">
            <param name="allowScriptAccess" value="sameDomain" />
            <param name="allowFullScreen" value="false" />
            <param name="movie" value="http://mysite.com/widget.swf?company=facebook" />
            <param name="quality" value="high" />
            <param name="bgcolor" value="#ffffff" />
            <embed src="http://mysite.com/widget.swf?company=facebook" quality="high" bgcolor="#ffffff" width="250" height="500" name="widget" align="middle" allowScriptAccess="sameDomain" allowFullScreen="false" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer" />
            </object>

Look I pass parameter company = facebook

http://mysite.com/widget.swf?company=facebook

Now I capture this parameter in my flash widget using actionscript by the following way

var globalParam = LoaderInfo(this.root.loaderInfo).parameters;
for (var element:String in globalParam) {
     if (element == 'company'){
           company =   globalParam[element];
     }
}

This actionscript 3.0 codes first loads global parameters and put them in globalParam variable. Now I just check whether there is a parameter named company or not. As I provided the company parameter in html so within flash object, I will get company = facebook

Very easy, right? Cheers!
