[FIX] Android XML Layout and Resource Design View Not Working In Eclipse

Hi sometimes XML views for your layouts and resources such as strings do not appear in the design view and you might be getting frustrated why this is happening. This post mentions a quick tip on how you can regain your original XML layout and/or resource design views.

The trick is simple. All you have to do is right click the layout or resource file in the "Package explorer" and then use the option "Open With" to open the file with the correct editor. In case of XML layouts, choose the Layout Editor option and in case of XML resources like strings, choose the Resource Editor option. Eclipse automatically saves your last choice so everything should work fine after doing these steps. I hope it comes useful sometimes. :)

How To Get Timeline In Your Facebook Profile

Earlier, many people were wondering how can they get timeline for their facebook page when they were helping us with votes in the library so I thought why not make a blog post so that it would help people out there to get the timeline feature in their profile.

What is timeline?: Who would better explain than facebook itself regarding its feature... Read about timeline.

Now to get timeline, go to Introducing Timeline page and if you are not already using timeline, a bottom footer will appear with the Get Timeline button at the right side.

All you have to do is click on that link to get timeline for your facebook. Timeline will be activated and you will be redirected to your timeline. I hope this helps you. :)

Adding Regular User To Sudoers File In Linux

Hi everybody, this time I am writing about the different command line methods of adding regular user to the sudoers file in linux or in more obvious way, giving access to root privilege to certain regular users. The sudoers file(located at /etc/sudoers by default[in my distro i.e. ubuntu]) contains the information of groups and users who can execute commands with root privilege. I'll list 3 ways of adding users to the sudoers list so continue reading the post.

Method 1
The first way is to use the usermod command to append the user to the admin group. Since the admin group has the privilege of executing commands with sudo privilege, adding the user to the admin group is one easy way to add regular user to the sudoers file. The example command is as below(Replace user with the proper username which you want to add to sudoers list):

sudo usermod -a -G admin user

Method 2
This method is similar as above however the command is adduser this time and the command is even more simpler to remember. Just specify the respective user to be added to the admin group as below:

sudo adduser user admin

Method 3
The last method I'm writing about is the safe way of editing sudoers files. Linux advises to use visudo command to edit /etc/sudoers so that possible errors while writing in sudoers file can be avoided. Typing just visudo would open the /etc/sudoers file for editing, and in case, if you want to edit sudoer file in alternate location, type visudo -f sudoer_with_path. Anyway, to add new user to the default sudoers file, type sudo visudo and add the line as below(Replace user with the proper username to whom you want to give sudo privilege) at the end of file:

user ALL = (ALL) ALL

I hope these methods come useful for you.

Hiding Information In Text Files Using Notepad [Windows]

Hi everybody, I had long ago read about hiding information inside text files using notepad and today I suddenly remembered while doing some other task. So I am sharing this little trick of hiding information inside the text file using notepad.

Open command prompt (Run-> Cmd) and then navigate to the directory (using cd command) where you want to save your text file. Now, type the following command:

notepad file.txt:mypassword

Replace filename part and password with yours as shown in the screenshot above and then you will be asked if you wish to create a new file or not(See the screenshot below) and then click on Yes to create the file.

Now enter your secret information in the file and save the file. Close the file and if you need to access the contents later, you will have to use the exact command you used while creating the file. If you or someone else edits your file without giving the password, your original hidden content will not be erased and you can still access the content with your original command.

I hope this trick is new for you. :)

Very Simple PHP Obfuscator Tool From Techgaun

Hi everybody, I've coded a very small snippet of code that will perform very basic PHP obfuscation so that programmers can protect their code from non-programmers. The obfuscation is by no means the advanced one and easily reversible. Only purpose is to prevent script kiddies and leechers from taking away your source code and distributing those as theirs.

Copying Files From Remote Server Using SCP In Linux

Hi everybody, sometimes you need to copy files from remote server and only thing you have access to might be SSh. If you can access remote server via SSh, then you can copy files from the remote server using scp(secure file copy). This short tip will help you copy files from remote server using scp.

Scp is remote secure file copy program that makes use of SSh for the data transfer and uses the SSh authentication. The general syntax is as below:

scp -P ssh_port user@server:remote_file_path local_file_path

Following was the command I used to copy a file from remote server to my computer. It will then ask for the password for the corresponding user before you can copy the file.

scp -P 222 netadmin@192.168.0.1:/home/kubh/Desktop/torrent_trackers_list.txt /samar/torrent_trackers.txt

Also, there are GUIs for this purpose as well such as WinSCP for windows and Krusader file manager and gftp for linux distros. GUI would make things easier but still I am used to with command lines and I hope you are as well.

I hope this helps. :)

Edit(Dec 19): Paths with whitespaces must be escaped with \ character. An example of this is as below:

samar@Techgaun:~$ scp -P 222 "netadmin@192.168.0.1:/home/netadmin/Downloads/Hostel\ Part\ III\ \(2011\)\ DVDRip\ 400MB/HOST.DVD_urgrove.com.mkv.002" /samar/Moviez/Hostel1.mkv.002
