I was reading a newspaper the other day and I came across an article plugging a new book “365 Ways To Change The World”. That’s one for every day of the year.

There are some good things in there that are easy to do and the author claims they can make a real difference to the world.

Here are some of the best ones:

• Stop eating prawns - More than four million tonnes of prawns are shipped every year. For every 1000 people who stop eating them, 5.4 tonnes of marine life can be saved. More information
• Join in the beautiful game - Buy three footballs. Keep one for yourself to play with, kick the second into a school ground as an act of generosity and donate the third to a youth football project in an African slum. Send it to the National Youth Organisation (Bidii Foundation) PO Box 28838, 00200 Nairobi, Kenya
• Stamp out junk mail - Contact the Mail Preference Service via the Post Office and tell them you don’t want unsolicited mail. You will be removed from mailing list for five years.
• Share your car - The average UK commuter drives 19 miles a day. Cutting that by half through car sharing would save 648kg of carbon dioxide over a year - the same as that absorbed by 216 trees.
• Don’t use plastic bags - There are 46000 pieces of plastic waste in every square mile of sea. Bags kill 100000 birds, whales, seals and turtles every year.
• Recycle your mobile phone - Fonebank is a scheme which lets you take your old phone to a collection point or put it in an envelope and post it to them for free. They distribute the phones all over the world. www.fonebank.com
• Save enery in the home - Replace three standard bulbs with low-energy alternatives and prevent 136kg of carbon being released into the atmosphere each year. If you turn your thermostat down two degrees you can save a further 272kg of carbon.
• Turn a loved one into a diamond - LifeGem in Chicago, Illinois, will take a few grains of your cremated remains and subject them to high temperature and pressure. After 18 weeks you emerge as a sparkling one-carat diamond.
• Ride a bike naked - The World Naked Bike Ride in June is an annual event where cyclists protest against oil dependancy and celebrate the power of the human body - naked.

I came across this article today that shows you how to hide a file inside a jpeg image using WinRar. It’s very cool but you can’t use it for top secret stuff as the information is stored in plain text and the large file size of the image looks a bit suspicious. However, if you want to keep something secret this is a good way of doing it.

First of all create your jpeg picture and your text file that you want to hide. I have a picture of Frank Lampard and a text file containing some secrets I never want anybody to see. Create a rar archive containing the files you want to hide.

Open up the Windows Command Prompt. Navigate to the folder where your files are stored and type: 'copy /b lampard.jpg + secret.rar football.jpg' where lampard.jpg is the original picture, secret.rar is the file to be hidden, and football.jpg is the file which contains both.

Open up the newly created jpeg image to see if it displays the original image. Then open it with WinRar and look at the files contained inside. There you have it. Your secret text file is hidden inside an innocent looking jpeg.

Take a look at the original article for more details.
