Reverse Engineer Finds Kindle's Hidden Features

bensafrickingenius writes "CNET's Crave site has an interesting article on Amazon's Kindle eBook reader, and the extensive reverse-engineering that fans of the device have accomplished. The site specifically points out the work of Igor Skochinsky at the Reversing Everything website. His work on the Kindle's Root Shell has revealed some fascinating goodies: 'Among the ones uncovered and described on his blog are a basic photo viewer, a minesweeper game, and most interesting, location technology that uses the Kindle's CDMA networking to pinpoint its position. There also are some basic location-based services that call up a Google Maps view to show where you are and nearby gas stations and restaurants.'"

    Honestly, why was it even included in the article posting? It's just a pointless summary of the content present in the original blog postings. 'course, I'm sure they appreciate the additional ad revenue...

      This is a problem with the "Blogosphere" in general. The vast majority (not all but certainly most) just echo news from other sources, or worse other blogs. They do not offer any insight, commentary or additional information on top of their source information. It's a crapshoot whether or not they actually write ANYTHING original rather than copy+paste.

      The worst is when you have a blog linking to a blog linking to the original info. FFS people...

      The net effect is old news gets constantly recycled and real news gets diluted. How many times have you seen a new blog post about something that actually happened months ago? The "9V battery contains AAAA cells" thing stands out as the most recent example for me: here (2 Jan 2008), here (9 Jan 2007), here (3 Jan 2007), here (23 Dec 2006). You have a "story" at LEAST a year old that has been copied verbatim at least four times!

      Original here (No date) as far as I can tell, since all of the above blogs link to it.

      Plus, all of these blogs have comment sections, which make them twice as redundant because the comments themselves also fail to add anything most of the time. If they do you'll never find them because there are so many other palces that run the same "story."

      Fight the watering down of information! NEVER link to a blog unless it provides something EXTRA to the news! ALWAYS take a few minutes to get as close to the original source as possible! If you run a blog yourself, work to ADD to articles you link to - personal thoughts, additional information, insightful discussion on the topic at hand - be UNIQUE. That's how you get a readership... by having something worth reading.

      If you want to duplicate and archive that's fine. But copy and pasting the same shit over and over with a new date is at best a lazy effort to get attention and at worst a dishonest excuse to keep the cobwebs off your otherwise worthless website. I would not criticize anyone for making a deliberate attempt to archive news, even trivial news. The "victories" of the Blogosphere are few and far between, and those victories are credited to that vanishingly small percentage of Blogs that actually do something relevant.

      And that is still no excuse for not adding to it. You can copy an article verbatim and still improve it's value by making some addition to it, either as a personal comment, further research into the topic, or a retrospective analysis of the article itself.

      The "Information Revolution" is more like an "Information Echo Box" - Plagarism is not revolutionary.

  5. Cellphone CDMA location by spaceyhackerlady · · Score: 5, Informative

    ...location technology that uses the Kindle's CDMA networking to pinpoint its position

    All current CDMA chipsets have location capability, due to E911 requirements for cellphones. They go through all sorts of gyrations to get a fix quickly when starting the GPS from cold (can't leave it running all the time or it would kill the battery), and to get a fix in "difficult" environments like urban canyons. They get a rough location by triangulating on cell towers, determine available satellites, doppler and code phase estimates, then tell the GPS what it should be listening for. Instead of taking several minutes from a cold start, they get a fix in a second or two.

    When you get a cellphone the service agreement will say that you agree to be located if you call 911 (read it, it's there). Any other location must be initiated by you, or with your permission, due to privacy issues. I did software for dedicated CDMA location devices and users got a special service agreement from Sprint. It said if you buy and use this thing, you are agreeing to be located.

    It's pretty slick.

      Do a search for "AFLT". They estimate the travel time from multiple cell towers (easy with CDMA) and work from there. They call it triangulation, though it's a lot closer to hyperbolic navigation.

  6. eBook readers are all wrong by charlie763 · · Score: 4, Interesting

    Okay, I's like to explain what makes ebook readers so bad and what needs to be done to fix them. Most Slashdotters will recall the days of the internet appliance (remember the i-opener?). What made them so bad is exactly what makes ebook readers so bad: they are only slightly less costly than computers, but are not nearly as useful. The internet appliances were essentially full computers with low specs because they only needed to browse the web. This made them almost as expensive as real computers. Their functionality was limited. They were proprietary and one had to purchase a service plan from a specific vendor. Now we see the same thing happening with ebook readers. They are as complex as computers and are just as expensive. They have limited functionality. They are proprietary. Here is the device I would like to see. A Bluetooth/USB ePaper display. Let a person's smart phone, computer render everything and tell the display what to do. The display wouldn't have to implement all sorts of complex file formats, the external device will take care of it. A display like this could be useful beyond ebooks. You might want one sitting next to your desk or in the server room displaying information. You might attach a keyboard to it with extra battery power and processing power. Maybe a bluetooth keyboard with extra battery power for charging your smart phone and ePaper display, allowing your smart phone to handle all the processing. The main point is that someone needs to produce a simple ePaper display around which others may innovate.

  7. Re:Tracking Hardware?!?!?! by orclevegam · · Score: 4, Interesting

    I think the important thing is that the kindle tracking is a pull, not push system. That is, the kindle unit can triangulate itself, and the firmware has a hidden routine for doing that and then pulling up your location on google maps, but it's not like it's an active tracking signal that anyone can lock onto. For this thing to be used to track someone without their knowledge extra software would have to be installed that constantly relayed to an outside source with the kindles own triangulated position. As a bonus this would likely do bad things to the kindles battery life, so just keep an eye out for sudden drops in battery life following any updates.
