Domain Name Service of Amazon Web Services is know as Amazon Route 53. Its a great service to manage, domain names and load balancing on multiple servers. In this post, I am going how you can configure Route 53, so that your domain points to the EC2 instance you own. First of all you need to own a domain and have account on Amazon Web Services. Once you have these get ready to go for the configuration. Its not that hard to configure, but if you don't get it then you won't be able to have your domain resolved to your EC2 instance.  First thing you need to do is open you Amazon Console and go to Route 53 Services. There you can create a hosted zone. And you'll get about 4 name server details, that you need to update in your domain registrar.The hosted zone should have your domain as example.com. And now click on the hosted zone and create record sets. First record set should be an A record. For this name should be example.com and value should be the ip of your EC2 in...

GitHub, the Social Coding Web Platform is introducing a new concept. Its taken from the *nix systems: Unix /Linux. In the *nix systems, to avoid haphazard actions leading to cause there is a mode called sudo mode. In this mode, to makes changes or for any operation that can cause severe results, the systems asks for password before execution. This way many possible hazards are reduced. The very same concept is being introduced by GitHub for more security. Thus GitHub will be requiring to enter password for some actions that have severe effect. For example to list some of the activities that will require password are: Adding public keys Adding email address This is definitely a good step of GitHub. Yes, of course, it is not going to ask for password continuously for all the actions so that won't be bothering. 

WordPress is a very popular open source content management system. Not just a content management system but some also say it to be a PHP framework for web development. What ever, WordPress is very popular in the PHP community for developing simple blogging sites to enterprise and high scale e-commerce solutions. The great number of available plugins and themes make it a good choice for developers. WordPress was developed by    Matt Mullenweg  and  Mike Little  on 27th May of 2003. And now it is 10 years old already. It has a download of 21 million times. And the latest release till date is WordPress 3.5.1 downloadable from  http://wordpress.org/download/  . WordPress is in about 66 million websites to the date. The number is growing everyday. Its in 120 languages. WordPress communities around the world celebrate 27th May as WordPress Anniversary. This year it was the 10th Anniversary.

The giant Google has been doing upgrades and updates in many of its field. Its also retiring some of its services. This year on Google I/O, Google turned out to be enhancing most of its services for Android, Web, Music, Gaming, Google+ and more. But yes it is also discontinuing some of its services. Google one of the discontinued service is Google Checkout. Google Checkout has is going to be completely disabled now. The last date of Google Checkout would be November of this year. However, Google is enhancing it as Google Wallet. Though Google Checkout is discontinued, Google wallet is going to be more enhanced. So if you are using Google Checkout then you should think of it soon. Another discontinued service of Google is Google Buzz. Its going to be completely discontinued by Google. The existing contents will remain. But no new contents can be added now in Google Buzz. Its a farewell to Buzz. 

Here in this post, we are going to learn to use a very useful PHP library for date Conversions . You can download the library from http://adf.ly/PXdXQ  . The file contains the library file nepali_calendar.php and an example file ' example.php ' zipped in. This library can be used for conversion of dates in AD to BS and vice-verse. Besides date conversion there are a few helper functions too like checking leap year, getting name of the month, getting day of the week and so on. However, the library has limitations. The limitation is on the range of date that can be converted. For AD to BS conversion the range is 1944 to 2022 and for BS to AD it is 2000 to 2089. You can also extend this library for yourself. A simple usage of the library is: <?php include 'nepali_calendar.php'; $cal=new Nepali_Calendar(); print_r($cal->eng_to_nep('2013','09','04')); //for ad to bs conversion print_r($cal->nep_to_eng('2070,'02','10'));//...

In our previous post, we discussed how we can mount Amazon S3 bucket into an Amazon EC2 instance. Now in this post we are going to discuss how you can solve a issue that occurs with this kind of mounting over HTTP in Amazon Web Services First unmount the bucket, for this we use the following command: fusermount -u directory_where_bucket_was mount Mount the bucket again: s3fs bucket_name directory _where_bucket_mounts

While working in PHP, you might come to this weird situation where you want to redirect to a page or send header information and you get this warning ' Headers already sent '. In this post, I am trying to help you get this issue solved. The first thing you can do is check if headers have already been sent or not. To check this the function you need to use is headers_sent(). For example: if(!headers_sent()){    //headers not sent you can send header }else{ //headers already sent } This is just a simple method to test if headers were sent or not. Now what we wanted to do here is to send headers even if the headers went sent. To do this, there are a few steps. First thing to do is start output buffering on top of the page. This can be done by the PHP function ob_start();.   So output buffering has been enabled. Now we want to check if headers were sent if they were sent then we need to clear them. TO do this we check for the status, and if its not clear then we do clear...

Recently, I have been working on Amazon Web Services. I have been using Amazon S3, RDS, EC2 extensively.  For my recent project that I am working on, I have a WowzaMediaServer running on a m1.xlarge instance [ cent os 6.3  x86_64 ]. And I have a bucket named fiercecaptial. What my situation is I need to mount the bucket in Amazon S3 into Amazon EC2 instance. Now, my friend to help me do this is s3fs , which I need to download. Well I suggest you to download the latest version. Once the latest version is downloaded what we need to do is extract the file. 'tar -xvzf filename.tar.gz' would help you extract the files. And the other step to get it installed is pretty easy: ./configure --prefix=/usr make sudo make install These are the common steps that you need to follow and this should help you get your s3fs installed.  And incase you have not installed your development tools that are required to compile the souce code then you need to run the following commands:...

In this post, I am going to show you, how you can use python to check domain availability rather to go to godaddy.com or any other domain lookup website to make this check. Oh yeah that means you can use this to find out the available domains too. Well lets get started. First of all you need to install python-whois. You can do this using your favorite tool pip. Its just a single step. pip install python-whois to verify that python-whois is installed its even more easy. python -c 'import whois' Successful installation means you get no errors running the above command. If you get 'No module named whois' then this means you are installation wasn't successful. Not that python-whois installed, we are ready to start using it. Lets do it by not saving in a file but opening python interactive shell and explore. To open python open terminal and hit enter after typing python. You should be in the python interactive mode >>> import whois >>> result=whois.whoi...

This is an example of sending email using GoogleMail SMTP authentication. You can give a try in CakePHP, this would definitely be helpful. <?php class ExampleController extends AppController{           public $name="Example";           public function sendsmtpmail(){ $this->Email->smtpOptions = array(                                                                  'port'=>$smtp_settings['email_settings']['smtp_port'],                                                                   'timeout'=>$smtp_settings['email_settings']['smtp_timeout'],           ...

CakePHP is a rapid web development framework for PHP language. And yeah I believe you are here to read this post only because you want to get started with CakePHP. And if its not then probably you want to know more about CakePHP, for more details why no you check this out :  http://cakephp.org/  ? Okey now lets get started. Download the latest version of CakePHP from GitHub  or clone it. Extract the archive file to the webroot directory i.e. for apache2 its /var/www/html and if you are on windows then for xampp it would be htdocs and for wamp it would be www. And if you are on a cpanel hosted web server then it would possibly be /public_html. So anyways you should be able to place all the files to your webroot directory. Now the directory structure should look like this: ->app ->lib ->plugins ->vendors ->index.php ->travis.yml ->.editorconfig ->.gitignore ->CONTRIBUTING.md ->README.md -> build.properties -> build.xml -> index.php app...

This post is about how python can be used to post tweets in twitter . To get started with this we need to install twitter for python which can be done from  http://code.google.com/p/python-twitter/  . It really has a very good documentation of installing twitter. To verify the process is similar like other ones, you just need to run "python -c 'import twitter" in terminal and if no errors intallation was successful. That means we can proceed. Lets create a twitter application now. To create a twitter application go to  https://dev.twitter.com/apps  .Once you create the application you need to put Access token, Access token secret, consumer key, consumer key secret into the code as follows: #!/usr/bin/python from twitter import * t=Twitter(auth=OAuth('Access token', 'Access token secret', 'Consumer Key', 'Consumer Secret'))         status_text=raw_input('Enter your message: \n') t.statuses.update(status=status_text,source="http:...

In this post I am going to show how you can update your Facebook status using python. The first and foremost thing to do is install Facebook for python. You can do this by downloading or cloning from  https://github.com/pythonforfacebook/facebook-sdk . Installation is quite easy. Unzip the file and run 'python setup.py install'. To verify Facebook Python SDK is installed you can run "python -c 'import facebook'". This should do absolutely nothing. No errors. If you get any error then Facebook SDK is not installed. Once Facebook SDK is installed, you can login to  http://developers.facebook.com/ . And create a new app. I believe this much you can do by yourself. Once an app is created in Facebook. Now open Graph API Explorer   which should look like as follows: Here you need to do is get Access Token by clicking the 'Get Access Token' button on the right top side. In the screenshot you can see the Access Token is displayed on the text field. Copy this t...
