In Ubuntu by default file browser will be hide folders from user if its name starts with ‘.‘ (dot). In this post I will list the different ways to see the hidden folders in Ubuntu.

1)Command line fans can use ‘ls -al‘ command to see the hidden folders.

GUI Fans can follow any one of these listed below:

2) Select Applications > System Tools > Configuration Editor

If System Tools doesn’t exists in Applications menu activate it as follows.

Do a right click at the left end of your gnome panel and select “Edit Menus” option. A window will appear in that check “System Tools option”. (See the image for reference).

Now select Applications > System Tools > Configuration Editor.

In the Configuration Editor window select desktop > gnome > file_views from the left column .

After that check show_hidden_files option. (See the image for reference).

3) Next is by navigating into the folder in which hidden folders exists and select View > show hidden files from the file browser menu.

4)But an easy shortcut exists for this. Navigate into the folder in which hidden folders were present and press ‘ctrl+h‘ and thats it, now file browser displays all folders starts with .(dot). Press ‘ctrl+h‘ again to hide the folders.

Using Magic SysRq key in linux

DK — Wed, 10 Jun 2009 08:51:12 +0000

Magic “SysRq” key, Have you used this key before?. Today i will give you a small tip based on this “SysRq” key.

In short Magic SysRq is a key combination in Linux which allows user to give some low level commands regardless of system’s state. You can read more about Magic SysRq key here.

Certainly when your system freezes you cannot do anything right?
Here is the procedure to use the SysRq key to reboot your linux distro (myself tested in UBUNTU) without any lose of data.

After your system got hanged. Press Alt+SysRq in your keyboard then by holding the those keys press the following keys one by one R S E I U B

For Example:
Press Alt+SysRq then press R for 2-3 seconds then release R (remember you should release only R not Alt+SysRq) and now move to S and press it for 2-3 seconds and release S then move to E and so on…
Please remember you should not release Alt+SysRq throughout the sequence (i.e until you finish releasing ‘B’)

Try to remember the key sequence using the sentence “Reboot Even If System Utterly Broken” .

The key sequence to shutdown the system is Alt+SysRq+R+S+E+I+U+O . Follow the same procedure as above.

Is it clear enough?

Today’s Ubuntu (Linux) tip is “how to install .bin extension file in Ubuntu?”.

When you are trying to install some .bin extension file for your Ubuntu OS for example RealPlayer11GOLD.bin you can’t install it directly as you are doing it in windows. To install such .bin extension file you need to know some simple terminal commands, which will change the .bin file so that Ubuntu can executes it.

After downloading the .bin file move it to desktop or other folder in your Home directory.

Then open the terminal (applications > accessories > terminal)

Type the following command if have you stored the file in desktop. (Remember type all the mentioned commands in this post without quotes.)

“cd desktop”

or replace the word “desktop” in the above command with the folder name where you stored your .bin file.

Then hit enter

Type “ls” and hit enter to verify your file is present in that folder.

Next type the following important command.

“sudo chmod +x filename.bin”

In the above command change the word “filename” with name of the file which you are installing.

For example if you are installing RealPlayer11GOLD type the following command

sudo chmod +x RealPlayer11GOLD.bin”

Hit enter.

Then it will ask for password. Give your login password. It will not appear in screen when you type, so don’t get confused. Type it without any mistake.

Now the you have changed the bin file into application that can be executed by ubuntu

To execute it type the following command

“./filename.bin”

Replace the word “filename” with name of the file which you are installing.

For example:

“./RealPlayer11GOLD.bin’

Hit enter. Then it will start the installation. It will alert you when installation is over.

Little Android Vs Windows 7

DK — Fri, 09 Jan 2009 12:32:00 +0000

To know basics about Google’s Android click here to view our early post.

We thought Google’s Android is for mobile but, people at VentureBeat experimented Android in Asus EEEPC 1000H laptop.And got success within 4 hours

Nearly all the hardwares in Asus EEEPC 1000H laptop were running perfectly with Android

As we already mentioned in our pervious post that Microsoft is building windows 7 to work more perfectly in netbook (to view the post click here).

Now after this big step the little Android can give some tough competition for windows 7 in Microsoft’s netbook market.

Most of the technologists were expecting that we can see a netbook can run with Android OS within 2010.

I think Microsoft want to face lot of challenges in both netbook and mobile market due to Android.

Really it is great work by Google because a single product (Android) of Google is giving trouble for two products (windows 7 and windows mobile) of Microsoft.

Expecting to see more fight with Microsoft in feature !!!
