Its past midnight but I can't sleep despite not being able to sleep last night. I'm with the graveyard shift but there happens to be a scheduled office drill today that I was not invited but rather, I was being mandated to attend.

Still, I managed to attend to the office drill and of course I was late. I placed two toothpicks between my eyelids to prevent them from closing and dropped some Visine to get the red out in sixty seconds. Gee it did not help. A lesson not to believe everything you see on television.

 Everybody noticed when I arrived; it's like walking in an isle when you're getting married. It's a feeling that is so inspiring until the facilitator started to mention my mistakes and failures in the office. I felt I was pushed into a tub full of soap water. I consider it to be one of my most embarrassing moments. "I should have left earlier", I said it to myself, if I had some clothes to put on. But because I forgot to get my laundry yesterday which I believed my uniform was with it. To my surprise when I came home, it turned out to be placed right inside my closet. At that time, I had a feeling that my moronic side is starting to overpower me.

Then lunch came I'm still wet with soap all over my body and  I thought everybody forgot about my tardiness  but it seems I was wrong for I was again called to lead the prayer.  I don't have that priestly look; it's more of a punishment for being late. I tried to hide, not that I do not want to say the prayer but I don't want them to notice my eyes. So no more bath soap, this time it I was soaked with detergent.

The office drill didn't go along smoothly as planned.  Office drill is not a drill about digging something in the office or preventing fire accident but it was more of like a protocol drill to freshen up our team and getting the respective jobs done. The result was a successful failure, we totally sucked. It was expected anyway; otherwise we won't be having that sort of drill.

The afternoon came; the toothpicks between my eyelids were removed not because I'm not sleepy anymore but because they broke. Apparently, they can no longer handle the weight of my eyelids. So I got these 3 sachets of Nescafe instant coffee 3-in-1 mix in a single mug and drank it. It was so effective that up until now at 3AM, I'm still awake.

Source Codes
To add source code listing we use the @ symbol
@print "hello world";@ is equivalent to <code>print "hello world";</code>

While downloading some pictures from a camera, I found them hard to manually rename its filename to a more meaningful title and not some random "DSC001323.JPG". After rename 10 or 15 files, i got bored, thinking this would take me forerver to rename them all for they are more than a thousand in total. If you can still recall that neat application called Irfan View, my life would have been alot easier.

Well anyway, lets change things we normally do and instead of using batch files we use vb script. A zipped version of the mass renaming script is also available for download.

I'm usually in front of the computer almost 12 hours everyday, except on weekends (I do have a life you know). In order to combat Carpal Tunnel Syndrome, I use an ergonomic keyboard and mouse. You can find some good stuff about office ergonomics at ergoware.com. To combat CTS, I use my left hand to operate the mouse even though I'm right handed. I only use my right hand when I play games (he he he).

The best thing to do though to prevent CTS is to always take a break in between work specially if you just sit in front of the computer the whole day. Remember, all work and no play makes Jack a dull boy.

Using the Ampersand ( & ) operator, it allows us to merge cells in an excel worksheet. you can create a formula to merge cells in excel or just insert it right away on the cell formula bar.

Problem:
And you wish to merge the two cells at A1 and A2 to the cell at A3

Given:
Cell A1 has the text "Lastname"
Cell A2 has the text "Firstname"

Solution:
* First position your active cell on A3.
* On the formula bar input the following: =A1&A2 [ENTER]

It should display LastnameFirstname on cell A3

To add a space and a comma, use the following:
=A1&", "&A2
it will output: Lastname, Firstname

alternatively you can also use the concatenate function, like this:
=CONCATENATE(A1,", ",A2)

Option Explicit 
 
Sub DeleteDups() 
     
   Dim x               As Long 
   Dim LastRow         As Long 
     
   LastRow = Range("A65536").End(xlUp).Row 
   For x = LastRow To 1 Step -1 
       If Application.WorksheetFunction.CountIf(Range("A1:A" & x), Range("A" & x).Text) > 1 Then 
           Range("A" & x).EntireRow.Delete 
       End If 
   Next x 
     
End Sub

Back with the good old days, we could use doskey to assign shortcuts to DOS commands. So, we could just assign ls to its windows equivalent like this:

Now, whenever we type ls, dir command is executed. We could also do that in Windows XP Command prompt, but the problem is after you have closed the window the doskey is also removed as well and we have to type it again every time we would run cmd.

There is actually a work around with that, we could modify our cmd shortcut in the start menu to add the doskey instructions there so that everytime the cmd is loaded the extra line is also executed as well.

i have modified my shortcut target from

the /k makes the window stay after the doskey is executed. For more additional options about cmd you can issue the command

here are a few common options:
/C Carries out the command specified by string and then terminates
/K Carries out the command specified by string but remains
/S Modifies the treatment of string after /C or /K
/Q Turns echo off
/D Disable execution of AutoRun commands from registry

Alternatively, you could also change the value of your registry at

to

Value name: AutoRun
Value data: doskey ls=dir

Actually, its better to use the registry option because after adding the code to the shortcut properties; the code completion for the command prompt no longer works.

Making a tarball and adding all files in the current directory then naming it as example.tar:

Compressing the tarball by zipping it (.gz):

Restoring a tarball gzip file example.tar.gz

Now, what if we are going to add a dynamic URL? It would be best explained by example, so here it goes.

For example: We are asked to check multiple sites for the following internet standards; W3C HTML Validator and WDG HTML Validator.

We have a reference cell A1 have the text http://tildemark.com. We all know the URL for the respective standards as:

W3C - http://validator.w3.org/check?uri=http://www.tildemark.com
WDG - http://www.htmlhelp.com/cgi-bin/validate.cgi?url=http://www.tildemark.com&warnings=yes

Now, all we need to create an entry such that each time we change the domain names the entry on each validator also changes.

Do the following on Excel:

Cell A1 - http://www.tildemark.com

I have some simple techniques you can use in order to remove multiple hyperlinks on a page:

Removing just one hyperlink
1. Right-Click on the cell and select Remove Hyperlink on the context menu.

Removing the cell format
1. Select the cells having hyperlinks. You can use CTRL+LEFT CLICK to randomly select a cell.
2. On the menu click on Edit. Hover your mouse to the option Clear and select Fomats. Please note that the cell is still clickable to remove the hyperlink completely you have to select Clear->All.

Remove hyperlink on selected cells the better way
1. Type in any text or number in a blank cell
2. Right-click and select Copy on the context menu.
3. While pressing CTRL, select each hyperlink you wish to be removed
4. On the Edit menu, select Paste Special.
5. Under Operation, click Multiply and then click OK.

Removing using a macro
Assuming you know excel programming you could create a macro to automatically remove the hyperlinks.
1. Start Visual Basic Editor. Alternatively you can press ALT-F11 to start the editor.
2. Double click the workbook you are using on the Project Explorer.
3. Type the following text:
