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. — Adam Pash

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've been waiting for your chance to buy a hot, hot Tesla electric car (such as their Roadster or Whitestar), good news. The electric car company is planning on opening 5 dealerships around the country 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. –Adam Frucci

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">
Technovision is showing off their 205-inch 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. –Brian Lam

Panasonic 1080p Projector: Visions of Heaven, Stratospheric Price
Definitely not in the budget for most home theaters, we think this high-end Panasonic PT-DW10000U 1080p projector might fit nicely into the HGTV Dream Home that the Gizmodo team is anticipating moving into this Sunday when they announce us as the big winners.
For $75,000, it comes with 3-chip DLP, four bulbs rocking 10,000 lumens, 1080p (1920x1080), 5000:1 contrast ratio, and an "auto cleaning robot" to extend filter life to 2000 hours. The unit can operate in temps up to 113 degrees thanks to a liquid cooling system and three big exhaust fans. Could get noisy. Definitely useful for those screening rooms in hell. – Charlie White and Curtis Joe Walker

New Video Watermark Tech Traces Bootlegs Back to Pirates
Future set-top boxes and gateways from Thomson SA are going to come with video watermarking tech that will allow investigators to pinpoint the origin of pirated videos. The tech, NexGuard, identifies "individual copies of the films distributed digitally to cinemas or on DVD as preview copies for reviewers and awards juries." Before video content leaves a gateway or set-top box, it embeds a watermark unique to each device using the box's digital video chip.
The watermarks identify both the "network operator distributing the content" and the individual device. A spokesman said that people "should not be upset about this unless they are widely redistributing content." Thomson sees it as a way to "slow down piracy without limiting the use of the consumer."
So, if you feel upset or limited, that means you're a pirate. – Matt Buchanan

Fujitsu flaunts color e-ink, future tech concept horn o' plenty
Posted Mar 20th 2007 4:00PM by Jeannie Choe
Filed under: Displays, Misc. Gadgets
We're feelin' what Fujitsu's done so far this year, but now we've got an idea of what it might bust out with in the near future. Last week's Fujitsu North American Technology Forum 2007 was an opportunity to flaunt not-yet-real (at least not in the US) concepts like color e-paper and FPcodes, among a few others. We've seen Fujitsu's elusive e-paper prototype before, and it's still not ready, but at least now we know that the 8-inch, 640 x 480 color display is about 0.03-inches thick, with a 12-inch version in the works and an ambitious goal to reach 2.5-meters. It requires virtually no power and can operate with a teeny boost of focused energy like radio waves from a cellphone. In addition to this e-paper flight of fancy, Fujitsu was showing off a waterproof RFID tag, along with those QR-killin' FPcodes and their vein pattern identification system we've seen before.Posted by Augustine at 10:59 PM

Siemens' Ostar LED: It's On
We have such a hard-on for LEDs that it seems like fate when this announcement comes from a company named Siemens. They have developed Ostar, an LED bulb that despite its 1 square millimeter size can put out 1,000 lumens of angelic light. Siemens explains the significance:
So LEDs are bright enough to light our houses and last 10 times longer than even halogen technology. We're ready to upgrade.A 60-watt light bulb emits 730 lm, while a 50-watt halogen lamp has an output of approximately 900 lm
If only we had a price or release date. – Mark Wilson

Raytheon claims world's first "polymorphic" computer
Posted Mar 22nd 2007 12:57AM by Evan Blass
Filed under: Misc. Gadgets
In what sounds like a pretty big deal, defense contractor Raytheon has developed what it claims is the world's first polymorphic computer -- a machine that can adjust its architecture on the fly and thus be equally adept at "front-end signal processing or back-end control and data processing." Specifically, the MONARCH chips, as they're known (for Morphable Networked Micro-Architecture, apparently), contain six microprocessors each running at 64 gigaflops and delivering more than 60 gigabytes per second of memory bandwidth and more than 43 gigabytes per second of off-chip data bandwidth. What's more, Raytheon says that its beautiful butterfly is simultaneously one of the most powerful and power-efficient chips available, outperforming a quad core Xeon by a claimed factor of ten. But don't get too attached, as you won't be seeing these DARPA-funded chipsets on the market anytime soon; instead, they're destined for GPS devices, radar, video processing systems, space gear, and anything else in which the military needs small, low-power, and radiation tolerant components.
