Google Does 13 Things Other Than Search!!!

 Google Search Features

Google have some features to get specialized or specific results.

1. Weather: To see the weather for worldwide cities, type “weather” followed by the city and state, or city and country. i.e, for weather information in Dhaka, Bangladesh, type "weather Dhaka, Bangladesh" in the google search box and you'll see the weather condition of Dhaka, the capital city of Bangladesh.
• similarly you can type time, sunset,sunrise.
2. Calculator: To use Google’s built-in calculator function, simply enter the calculation you’d like done into the search box. suppose: 5*9+(sqrt 10)^3+ln(3E8)=
3. Converter: You can use Google to convert between different units of measurement of height, weight, and volume among many others. Just enter your desired conversion into the search box and Google will do the rest. Search example: 1light year in km or -40 celsius in fahrenheit.
4. Public Data: To see trends for population and unemployment rates of  states and counties, type "population" or "unemployment rate" followed by an US state or any county. i.e: GDP Bangladesh, or unemployment rate US.
5. Synonym Search: If you want to search also for your search terms synonyms, place the tilde sign (~) immediately in front of your search term. ex: ~fast food
6. Dictionary: To see a definition for a word or phrase, simply type the word “define” then a space, then the word(s) you want defined. Note that the results will define the entire phrase. example: Define ambiguous.

Syntax Highlighter wordpress

How to hightlight codes you published in wordpress.com?

Here is the solution:

You have to post your code in between the tag. Write down your language name replacing your_language. That's all. :)

[sourcecode language="your_language"]
//your code here
[/sourcecode]

Here is an example of how to represent a python code in WordPress:

[sourcecode language="python"]
import turtle # allows us to use the turtles library
window = turtle.Screen() # creates a graphics window
rightAngle = turtle.Turtle() # create a turtle named rightAngle
rightAngle.forward(150) # tell rightAngle to move forward by 150 units
rightAngle.left(90) # turn by 90 degrees
rightAngle.forward(75) # complete the second side of a rectangle
window.exitonclick() # graphics window wait for your click to exit
[/sourcecode]

This will look similar to this:

import turtle # allows us to use the turtles library
window = turtle.Screen() # creates a graphics window
rightAngle = turtle.Turtle() # create a turtle named rightAngle
rightAngle.forward(150) # tell rightAngle to move forward by 150 units
rightAngle.left(90) # turn by 90 degrees
rightAngle.forward(75) # complete the second side of a rectangle
window.exitonclick() # graphics window wait for your click to exit

The language parameter in the tag controls how the code is syntax highlighted. Default language parameter
is "text"[No highlighting].

At this moment wordpress.com is supported the following language:

1. actionscript3
2. bash
3. coldfusion
4. cpp
5. csharp
6. css
7. delphi
8. erlang
9. fsharp
10. diff
11. groovy
12. html
13. javascript
14. java
15. javafx
16. matlab (keywords only)
17. objc
18. perl
19. php
20. text
21. powershell
22. python
23. r
24. ruby
25. scala
26. sql
27. vb
28. xml

The shortcode also takes variety of parameter to customize output, but they are optional:

1. autolinks (true/false) — Makes all URLs in your posted code clickable. Defaults to true.
2. collapse (true/false) — If true, the code box will be collapsed when the page loads, requiring the visitor to click to expand it. Defaults to false.
3. firstline (number) — Use this to change what number the line numbering starts at. It defaults to 1.
4. gutter (true/false) — If false, the line numbering on the left side will be hidden. Defaults to true.
5. highlight (comma-seperated list of numbers) — You can list the line numbers you want to be highlighted. For example “4,7,19?.
6. htmlscript (true/false) — If true, any HTML/XML in your code will be highlighted. This is useful when you are mixing code into HTML, such as PHP inside of HTML. Defaults to false and will only work with certain code languages.
7. light (true/false) — If true, the gutter (line numbering) and toolbar (see below) will be hidden. This is helpful when posting only one or two lines of code. Defaults to false.
8. padlinenumbers (true/false/integer) — Allows you to control the line number padding. true will result in automatic padding, false will result in no padding, and entering a number will force a specific amount of padding.
9. toolbar (true/false) — If false, the toolbar containing the helpful buttons that appears when you hover over the code will not be shown. Defaults to true.
10. wraplines (true/false) — If false, line wrapping will be disabled. This will cause a horizontal scrollbar to appear for long lines of code.

All folder became shortcuts!!!

This is new kind of virus, I guess.I was infected by it too. All my folder in external hard-drive had become shortcut. I didn't know how to get my folder back that had turned to shortcut to become a folder again without loosing any files. I was searching through web, and suddenly found a strange solution, which worked nice.

Go to Start->Run ->cmd
change your directory to the affected drive or folder. i.e  H:/  and press Return/Enter.
Now write or paste this in your command prompt: attrib -r -a -s -h /s /d


After a while it'll be OK and you'll get access to your data.  But it'll be safe if you update your anti-virus and run a full check and open the drive.
Hope this will solve the problem.
