Solution

If you are quite well in database you can simply rewrite the URL key in the database, else the best way to solve this problem is to write a redirect. To define a redirect follow the below steps.

1. In the admin page, select Catalog -> URL Rewrite Management.
   

   Magento Catalog URL Key Rewrite

2. Click on Add URL Rewrite button.
3. Select Custom from the drop down button.
4. In the new page that is opened, select the ID Path of the URL. For example if you need to change www.bytechip.com/about-us to www.bytechip.com/about , then the ID would be www.bytechip.com/ and the Request Path is about-us and the Target Path is about.
5. Select Permanent(301) as the redirect type and click on save to apply the changes.

Hide all Posts from a Friends, Pages and Apps in Facebook

   Facebook Hide Posts

2. Click on “hide this post” option in the drop down.
3. Now you will be provided with three options, to restore the hidden post, to unfriend the person and to hide all the posts from the person.
   

   Facebook

4. Click on Hide all by <friend_name> link to hide all the posts from the person.

Note : Earlier blocking people used to be one option when you click on the x button in the top right but now they have modified it, may be because users tend to click on it accidentally.

Proxifier

This is the probably the best and the fastest of the three proxy softwares. Proxifier works on MacOS and in Windows. Using proxifier you can connect using the HTTPS or the SOCKS proxy. Proxifier lets you browse any blocked websites. The good thing is you could download torrents in your restricted internet. There is no Linux version of Proxifier and its not compatible with WINE or other emulators.

Proxifier

UltraSurf

This proxy isn’t that fast as compared to Proxifier. Ultrasurf is completely free to use. Torrent download is somehow not possible using Ultrasurf. The good thing is it runs on Linux with WINE emulator. So if you are Linux user, you can very well use this.

Ultrasurf

Tor

Tor project is one of the widely proxy softwares. Tor supports Windows, Linux, MacOS. The best thing is you can use Tor to bypass restrictions in your smartphones too. The bad thing is the speed. Tor is the slowest of all three applications listed here. Torrent downloads are possible using Tor, if readers insist we would also like to write a tutorial for that.

Restrictions are made to maintain some order in the workspace, but breaking them for a good purpose is never wrong. I hope that these applications will solve your network restrictions problem. In our next tutorial we will introduce how to bypass file size limit restrictions made using Squid and other firewall services.

Magnify Screen using Shortcut

The shortcut for magnifying the Screen is

Zoom Up – Windows Key + Scroll Up

Zoom Down – Windows Key + Scroll Down

The Level of Zoom depends on the amount of the scroll. To my amazement the tool can zoom to a much greater level than expected.

Persisting an Object

A custom function has been created to persist a single object using Hibernate. The arguments are the Class name and the object to be persisted. The function at present takes a single object, however you can tweak to persist a collection of objects. My project demanded me to mostly persist a single object, so I have designed it this way. While persisting an object SaveOrUpdate method is used. Therefore if an entry already exists it overwrites it else creates a new entry.

Retrieving an Collection of Object

Another function getObjects is used to get the collection of objects in a List (java.util.List). The arguments are the class name and the query. In both the functions a new SessionFactory has been created to avoid runtime errors.

1. Constructor to give the DB details such as Database Drive Name, Database URl, Database Name, Username and Password.
2. Execute Method to perform executeQuery().
3. Updatea Method to perform executeUpdate().
4. Method to close the Database connection.

Usage of Database_connector

The usage of this class is relatively much simpler. The below code illustrates the usage of this class to connect to a Database and perform the three methods.

/* Database_connector class with constructor(driver_name,db path,db url,username, password) */
Database_connector db = new Database_connector("com.mysql.jdbc.Driver", "jdbc:mysql://localhost:3306/", "myDatabase", "root", "password");
 
/* Execute method - Argument is the statement*/
ResultSet student_resultSet=db.execute("select * from student where department="computer");
/* Do things like printing or other actions from the ResultSet */
 
/* Update method */
int result =  db.update("update student set status="dismissed" where id="56");
 
/* Close Db */
db.close();

Note

1. Always call the constructor when a object of Database_connector is created.
2. The ResultSet returned could be null if no record found, so in your actions part, check for this condition before calling the next() function.
3. Update will return -1 if it failed or other integers corresponding to the original executeUpdate() method.
4. Best practice is to call the close() method once the work is over.
