Hide files in JPEG images

hide%20files%20in%20images.png

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

Pavonine showcases 24-inch MIRACUBE stereoscopic LCD monitor

Posted Mar 19th 2007 7:48AM by Darren Murph

Filed under: Displays

While not quite as flashy as IO2's floating M3 Heliodisplay, Pavonine's forthcoming 24-incher still manages to put an interesting twist on your average computer LCD. Aside from touting a respectable 1,920 x 1,200 resolution, front-panel controls, and a DVI input, the MIRACUBE monitor boasts stereoscopic abilities most commonly associated with those gaudy head-mounted displays and cheap 3D gimmicks. The screen can only muster 1,920 x 600 resolution while displaying in the third-dimension, and requires (a presumably bundled) pair of glasses in order to experience the full effect. No word just yet on how much Pavonine plans on charging for the G240S once it departs the CeBIT floor, but we'd probably wait for a hands-on review before plunking down for such hit-and-miss technology.

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?

Luxio

[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
