Hide files in JPEG images
The Tech Tray weblog has posted a tutorial for hiding secret files inside JPEG images using the popular Windows archiver, WinRAR, and a little command line magic.
Basically, you create a .rar archive of your to-be-hidden file, then run a copy command from the Windows command line (with the /b binary switch) to embed your secret file in your image. After you complete the process, you can open and view the JPEG like any other image - the only thing that might tip off that the image has got a secret is a potentially bloated file size. To grab the secret file, you just use WinRAR to extract the file from the image.
It may sound like a lot of work, but it's a pretty simple process (watch the video to see how easy it is). This is a neat trick, but if you want to get really serious about encryption, you'll want to encrypt your data with TrueCrypt.

Hiding Files in Jpg's
Introduction
Here is a tutorial on how to hide files in Jpg's. Please note it isn't the most secure method, because the information is stored in plain text but it's still cool to play with. A simple solution to make this more secure, is to use encryption on the RAR file when your create it, but thats not the point of this tutorial :) The idea is to show how files can be 'slammed' together, to stop the average PC user from finding them.Video Tutorial
Please click here to see the video tutorial.Step by Step Instructions
You will need the following..- Windows 2000 / XP (probably Vista, too!)
- Basic Knowledge of the Command Prompt
- WinRar
- Gather your image and the files you wish to lodge into it. Here I have a meeting.txt which which I will slap inside my secret.jpg
- Add the files you want to hide into a new RAR archive
- Open Command Prompt
- Go to the folder where your files are located, in this case 'C:\hidden'
- Type 'copy /b secret.jpg + meeting.txt.rar lizard.jpg' where secret.jpg is the original picture, meeting.txt.rar is the file to be hidden, and lizard.jpg is the file which contains both.
- Test the JPG by opening it, and verifying it still opens. If it does, try opening the file with WinRar!
- The completed RAR file!
- Here is the image I created when making this tutorial!

Tesla Opening Electric Car Dealerships This Fall
If you live in NYC, Chicago, Florida, Northern California or Southern California, you're in luck. They hope to open more dealerships soon after, as they're able to pump out more product. Is this the start of the age of the mainstream electric car? We sure hope so.
CNET [via Mobile Mag]Introducing the 205-inch Technovision Luxio LED TV/HDTV : Big Enough to Park Two Mini Coopers On
LCD HDTV : Big Enough to Park Two Mini Coopers On">
LCD LED HDTV at CeBit, that makes the formerly buff Sharp 108-inch LCD feel downright pathetic. That's enough space to park two mini coopers on, side by side. Wait...TechnovisionWho?
[UPDATED: Aha! It's an array of LEDs, not an LCD]
The Italian company, in operation since 1987, specializes in displays for outdoor areas. Ohhh. So this is like a jumbotron. Except for inside, and HD. I refuse to believe that these are single pieces of glass. Likely they're comprised of a few panels joined together like some of the "big" TVs we saw at CES.
Regardless, that much glass -- over 15 feet by 8 feet -- forming a single picture, is rad. They unveiled them at a yacht show in February, so you can imagine the market they're aiming for. We've no idea if these will ship soon, or in the US. But that doesn't matter. You can't afford this TV.
