With all the buzz around Twitter these days, it's no surprise that we see new clients popping up everywhere - on our desktops, the web and as mobile applications. While some applications are done quite well, it can be difficult to find the one that has the features that you want. But like all software developers, you have a choice - you can go ahead and build one of your own. That's where Twitter4J fits in.
I first became aware of Twitter4J as I was working on my Twitter client
using ECF. No matter what feature I needed from Twitter, it was
supported in Twitter4J. Of course, you can integrate into any Java
application from version 1.4.2, and there's also support for the
Android platform. In this article i'm going to give a brief overview of
how to use the framework to connect to, and use, Twitter. With the
basic building blocks that the library provides, you can create your
own rich Twitter interface.
It couldn't be easier to get going with this library - simply download the latest version, and add the core library to your classpath.

Hi,
I’ve been busy with things and so not too many updates lately. Not to worry thought, we have a brand new course and lots of free videos coming out soon on advanced MySQL.
In the following podcast (it was a video but I changed my mind …), I talk about the pragmatism of the Zend Framework dudes.

Here’s how this works:
You can guess the location of a user by their IP and Rasmus Lerdorf wrote a nice API to do that at http://geoip.pidgets.com/. Using that, you can read the IP in PHP and call the API with cURL:
if ($_SERVER['HTTP_X_FORWARD_FOR']) {
$ip = $_SERVER['HTTP_X_FORWARD_FOR'];
} else {
$ip = $_SERVER['REMOTE_ADDR'];
}
$url = 'http://geoip.pidgets.com/?ip='.$ip.'&format=json';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
$data = json_decode($output);
$lat = $data->latitude;
$lon = $data->longitude;Link To Full Story: ria.dzone.com
Data-centric development is an exciting new Rapid Application Development (RAD) feature in Flash Builder 4 beta 2, which helps traditional web and novice Flex developers to quickly build rich data-centric Flex applications that fetch data from various back-ends including ColdFusion, PHP, BlazeDS, LiveCycle Data Services ES, web services, and HTTP services.
Because web services are such a popular mechanism for exchanging data between different applications and platforms on the Internet, Flash Builder 4 provides easy and efficient ways to import, explore, and use web services. Through its unified workflow wizards, Flash Builder 4 helps developers quickly build Rich Internet Applications that leverage existing corporate or public service infrastructures, including web services.
In this article, I will demonstrate these capabilities by showing you how to build an application (see Figure 1) that uses Zenfolio's web service to display photos.

Web apps and web services multiply like rabbits. They’re all fun to play with (like rabbits) and fun to integrate into other projects (unlike rabbits). But learning a new API every other day isn’t feasible or fun. And that’s the problem the Yahoo Query Language (YQL) is out to solve.
Think of YQL as the API for the web, the one API to rule them all. It’s not a hard one to learn, so let’s get you up to speed right now!
Yahoo has put together a pretty nice console for us to flex our muscles with YQL. Load up that console, and let’s explore it.
In the right sidebar, you can choose a “table” in the “database”; a sample query will show up in the statement box at the top. To the right of the statement box, you can see what the corresponsing REST query would. Below, you have the data returned from the query; you can receive data in either XML or JSON.
So, let’s try a query!

90% of beginner PHP programmers trust their users. I may have completely made that statistic up – but I’m pretty sure it would be close enough to that figure. Sure, the majority of the people who will use your web application will be nice people who would never dream of damaging your website. However, all it takes is one a!*hole with enough knowledge about web applications to ruin the entire show. If you’re asking the user to enter a number, check that what they entered is actually a number. If you’re asking a user to enter their email address, check to make sure that what they entered was actually an email address.
if($condition) //do something
The above piece of code may work etc, but it makes your code far less readable. Instead, you should always try to use full parenthesis:
if($condition){ //do something }
It just makes your code easier on the eye and gives it some structure, that’s all.
When you are constantly assigning variables onto one another, you’re not only using up memory – you’re also making it difficult to track any bugs that might pop up:
require_once("inc/vars.php"); $tax_insurance = $total_tax; $cost = $tax_insurance + $other_variable; $another_cost = $cost + $other_variable; $cost = $another_cost; $goddamit = $another_cost;
Ugh.

During the last two years, I was involved in several projects deployed on the Amazon cloud. Being a relatively early adopter was a fantastic experience that provided lots of opportunities to burn my fingers and learn from mistakes. It also seriously challenged my view of scalable software architectures. I spoke about key lessons learned at CloudCamp London last week – here is the summary of that presentation.
Before I start, I’d like to point out that judging from this post it might seem that I have a negative view of cloud deployments, but nothing could be further from the truth. I have many nice things to say about the cloud, but lots of other presenters at CloudCamp do that all the time. I wanted to play the devil’s advocate a bit and expose some of the things that you won’t necessarily find in marketing materials.
Before the cloud, I was used to investing more in machines which were more important. Database boxes would have better power supplies than web servers, ideally redundant. Content servers got better disks and lots of them. A nice Cisco appliance would balance requests to web servers, and was infinitely more reliable than them. Web servers, for all I cared, could crash and burn at any time, as long as they did not all decide to do it at the same time. With the cloud, this isn’t possible. No matter how many virtual cores or memory you rent, all the boxes are running on very similar hardware. Or, putting it in another way:

I’ve never really got the hang of PHP frameworks and have tended to use my own custom built CMS but even with this I still find myself writing the same code over and over again. In the past I’ve dabbled with CakePHP and the Zend Framework and not really got very far, so a few days ago I downloaded CodeIgniter. Although I’m extremely new to this I was pretty blown away by the simplicity of setting things up and getting an actual webpage that processes something online.
CodeIgniter uses the MVC or Model View Controller architectural pattern, if your not familiar with MVC it is a logical object orientated development approach. below we look at a simple example of how we use the MVC.
