How To Tell If The Image Is Fake Or Original?

Posted by Blues with 122 comments


Many a times we come across images where we are stuck into thinking if it is original or photoshopped (fake). Image Error Level Analyzer or simply ELA, is a free web service which helps you in determining if the photo is real or not. 

How does it work?


Error Level Analysis allows you see to see the difference in quality level, represented by brightness. Things which are very bright have been edited most recently, whilst duller parts have been resaved multiple times. This allows you to see not just which parts of the image have been changed, but in what order the changes occurred.


You just have to provide an image URL and hit Process. It will then analyze the image and show results instantly after the processing is complete. You can easily compare and tell if the image is original or modified using Photoshop or any other image editor.

Microsoft Office Tricks

Posted by Blues with 2 comments

No matter how long you've been using Microsoft Office, you probably don't know every trick and shortcut there is. Maybe you've stumbled upon a few shortcuts by accident after years of doing things the hard way. There are an incredible number of shortcuts hidden within each Microsoft Office application that can cut time and frustration out of your daily activities. Here are just a few of the techniques you can use to get even more out of Microsoft Office.

Special symbols
Special symbols can be inserted by using "Insert/Symbol" on the menu. However there are many shortcuts that make inserting symbols even easier.

The Autocorrect function allows you to enter common symbols quickly. A few examples:

(c) will become the copywrite symbol
(r) will become the registered symbol

If there are symbols you use a lot, such as foreign currency symbols, you can edit the autocorrect list to create your own combinations.

International characters are a snap. Simply type "CTRL+(symbol)" followed by a letter to add a diacritical mark to a letter. Some valid symbols are:

apostrophe (') creates an acute accent
grave accent (`) creates a grave accent
carat (^) creates a circumflex
colon (:) creates a diaresis
tilde (~) creates a tilde
the at sign (@) creates a ring
comma (,) creates a cedilla

So to create the letter "A" with a tilde type CTRL+^ (which is CTRL+SHIFT+6) then type "a". This trick doesn't work in all Microsoft Office applications, but it does work in Word and Outlook which are where they are needed most often.

Format Painter
An often-overlooked feature in Microsoft Office is the Format Painter. It appears as a little paintbrush on the toolbar. When this icon is selected, it makes a copy of the formatting of the text where the cursor is located. The cursor changes to a paintbrush, allowing you to "paint" that format into a new section of text. By double clicking on the icon, you can paint the format over and over again. To cancel Format Painter simply press ESC.

Shortcut keys
All Microsoft Office applications have huge collections of shortcut keys. While it might be overwhelming to memorize them all, skim the list of shortcuts in the help document to see if there is an easier way to do your work.

Also remember that you can access menus by pressing ALT-letter where the letter is the underlined letter in the menu. For example, to insert a row in Excel you can press ALT-I (to select the Insert menu) then R (to select Row). Often it's easier to use keyboard commands rather than take your hand off they keyboard to use the mouse.

Many more Microsoft Office tips
These are just a few of the tips that users can pick up by enrolling in Microsoft Office training courses. Even if you use Office in your job every day, you might be surprised just how much you are missing. A day's course could save you hundreds of hours of lost productivity as you learn to do your work more efficiently.

Access Any Website Or Forum Without Registering

Visit any forum or website to find something useful and they will ask you to register. Every time a forum asks me to register, I simply close the site. You would probably do the same. But this time, lets face it.
Before I begin, you should know how things work. All websites and forums will block unregistered users, but they won’t block Google Bot. What we will do is to switch our User Agent to that of Google Bot and freely browse any website or forum without registering.
First grab the add-on for Firefox called ‘user agent’ here and install it. Now go to Tools > User Agent Switcher > Options and then again to Options.
 

Select User Agent from the left sidebar and click Add. Now in the description field type:
crawl-66-249-66-1.googlebot.com
and in user agent field type:
Googlebot/2.1 (+http://www.googlebot.com/bot.html)
as shown in the screenshot below.
 
Select Google Bot as your User Script by going to Tools > User Agent Switcher.

 
Now browse any website or forum without registering. Alternatively you can also check out BugMeNot, it is a free online service where people share login information of thousands of websites and forums. Enjoy!
