Rooting Thrive ... Done!

Thanks to dalepl and his unbelievably awesome Universal Easy Flash Tool - I now have root on my Thrive.

The best part is the process to get there, it was as easy as

  • Install the correct ADB drivers on your laptop (available within the same zip file from dalepl)
  • Connect the Thrive to the laptop via USB mini and ensure it is connected to the charger at the same time.
  • Run the batch file Universal_Easy_Flash_Tool.bat

Confirm the fact that you want to root the device...

And pick the correct ROM that you are currently on...

And after about 4 reboots of the device - you are done!

Thank you @dalepl and @TurnYourBackAndRun - honestly Toshiba should be paying you for keeping their devices relevant. Now to kick some pre-installed crud off the device.

Dynamic DNS on my Tomato Router

Here is the problem statement - now that I had my router running a custom TomatoUSB build, I wanted to open it up to the Internet so that I could access my music and data from anywhere.

The first step though, was to establish a way to address my router via the Internet. Now, I get a dynamic IP address from my ISP; so I had to find a way to keep track of the latest address. The answer, of course, was to use a dynamic DNS (DDNS) solution, of which there are dozens available. But as it turned out, my case was more complicated than that.

I chose the FreeDNS service offered by afraid.org. Tomato firmware has native support for their dynamic DNS service built in. But more importantly the tagline on their website read “Why is it free? It's quite simple. We wanted a challenge... that's it.”.

To set my site up, I had to delegate the nameserver function for my domain to my hosting provider. My initial idea was to delegate a subdomain to the FreeDNS service, and then update the IP address directly from my router. Unfortunately my hosting provider did not allow delegation of sub-domains to a different DNS provider. In other words, they did not allow NS records to be created for their inconsequential customers like me. They only allowed A, TXT or CNAME records. CNAME records - that gave me a way out.

I created a sub-domain on one of the free domains provided by the FreeDNS service - in my case it was mooo.com. The name of the sub-domain did not really matter, any available one worked just fine. Then I set up my Tomato router to update the IP address of this sub-domain automatically.

Finally, I set-up a CNAME pointing a sub-domain from anarchius.org to the newly created sub-domain on mooo.com. Presto - sub-domain.anarchius.org now resolved to my WAN IP address. Here is how my DNS records look now:

There you are, Dynamic DNS on my Tomato router up and running, linked directly to my own domain. Bring on the possibilities.

Impulse Purchase

At long last, my Nokia 5800 has been retired from active service.

It has been replaced by my new Samsung Galaxy SII. And all this happened within a matter of a few hours.

I had been eyeing an Android phone for a while now. My first choice would have been the vanilla Nexus series - but they tend to be far too pricey and missing carrier specific frequency capabilities on their wireless chipsets. The next choice was the Galaxy series from Samsung. And that is when I saw this deal from RadioShack:

While this was about $50 more than the Black Friday deal from Radioshack, it was still a full $100 less than the discounted price on AT&T's website. And it hit my key checklist items.

  • A tried and tested phone chassis - the Galaxy S II is the second in the highly successful Galaxy series.
  • Minimal UI customization - unlike the HTC Sense UI, TouchWiz UI is relatively lightweight and optimized for speed.
  • A known upgrade path to Ice Cream Sandwich.
  • No known carrier hindrances to phone capabilities.
  • Speed and responsiveness.

The Galaxy SII hit all points on the checklist - making the decision to switch surprisingly quick and painless. And RadioShack was not that bad an experience, as far as the tactical switch went. On a side note, I need to remind myself that RadioShack is probably a better option for buying electronics when I want something outside the standard mainstream products.

RIP: my ageing Nokia 5800 - you were a trailblazer, and were better than you had any reason to be. Yet, the trail was left cold after you, for no fault of yours. You will be missed.

TomatoUSB on Netgear 3500L

Upgrading a Netgear 3500L to the latest TomatoUSB build. This worked for me as of December 01, 2011 - with no guarantees that will work for you or at any other time.

Required ingredients:

  • The trailed DD-WRT build to perform the first upgrade. Filename: dd-wrt.v24-15704_NEWD-2_K2.6_mini-WNR3500L.chk
  • The correct TomatoUSB version - Build 54, Kernel 2.6, CPU MIPSR2 and feature-set Extras or Ext. This is what I used, but you might check the latest version here. Filename: tomato-K26USB-1.28.9054MIPSR2-beta-Ext.rar
  • WinRAR or 7-zip or a related utility to unzip the RAR file.
  • Some timer - either an app on your phone or a watch with a seconds hand.
  • A pushpin of some sort.
  • A printout of a document that looks something like this.
  • A laptop or desktop of some kind that has a working modern browser.

Procedure:

  • Ensure your firmware files are identified, available and ready to go. See above for the two files you need to keep available. Use WinRAR or 7-Zip to unzip the .rar file. You will get a .trx file along with a changelog. Rename the .trx extension to .bin.
  • Connect your computer to the router using an Ethernet cable, if you do not have extra cords, use the one which used to connect the router to the external WAN. In either case, ensure the External WAN is disconnected.
  • Set your computer to a static IP of 192.168.1.8 (Ensure you are doing this to the wired LAN connection)
  • Perform a 30-30-30 reset using your push-pin on the depressed reset button on the back of the router. You might want to use the timer to ensure you are actually keeping it depressed for 30 seconds.
  • Wait for the router to boot back up. Using your browser, head over to http://192.168.1.1, and use your default credentials login: admin and password: password to log in.
  • Using the Upgrade option on the Netgear admin menu, use the .chk file you downloaded from the DD-WRT site. Note you are not using the bigger TomatoUSB firmware yet.
  • Wait, no seriously wait. Wait till the lights get back to normal. Wait. Wait to see that you can access the new admin interface.
  • Perform the 30-30-30 reset. Wait for the router to come back up.
  • Now head back over to http://192.168.1.1. You should be automatically logged in, but instead will be asked to set an admin account with password. You can set this to be whatever you want, your firmware is just about to be flashed.
  • Go to the Administration tab and then Firmware Upgrade sub-tab. Select the TomatoUSB file that you extracted from the RAR archive and renamed to a .bin file.
  • Again wait. For all the frenzy to subside. After you can see the router administration page again, wait some more.
  • Perform another 30-30-30 reset. Wait for the router to come back up.
  • Again head back over to http://192.168.1.1. Login using the Tomato default credentials: no login required and password: admin
  • Set up basic wireless services, located under. Disconnect the Ethernet cord, reconnect the router to the WAN network, get-up sit on the couch and continue configuring your brand new router firmware.
  • And yes, keep away the push-pin, the timer and set your wired connection back to dynamic IP.

That was it, and if you have been following along, my Toshiba thrive connects beautifully to the new router via SMB and I can now access all the media I have on my RAID, wirelessly over the home WiFi network. Cloud anyone?

Freedom to hack: 1 - Closed systems:0.

Upgrading my Netgear 3500L

The story so far...

My tablet could not access my ReadyShare NAS that ran on my Netgear 3500L. So far, it seemed as if the problem was with the router and it's implementation of SMB. After much wrangling of hands, cussing of SMB and praising the virtues of hackable gadgets, I decided to change the stock firmware on my router.

My Open Router, is a great resource for available after-market firmware. It also has that typical Open Source lack of polish, that makes the process of re-flashing a real journey - filled with uncertainty and trepidation. Here is an example, the initial page for the 3500L has a total of 5 open source options, and the very first article after the review is a “de-bricking” tutorial. If you were not aware, bricking happens when you mess things up so bad, that the only true use of your cuboidal device is to use it as - you guessed it - a brick.

The key with open source projects is to just jump in and start reading. Do not try to form an approach - you will mostly be wrong. The most useful nuggets are mostly hidden - like the curiously named Peacock thread, or Redhawk0's firmware recommendation thread. If you were planning on using DD-WRT, you should not be touching the reset button without reading both these threads.

After about 30 tabs worth of reading, I learnt a few things. In no particular order, but relevant to me were...

  • Doing the 30-30-30 reset.
  • If you do not do a 30-30-30 before and after a firmware upgrade, you could brick your device.
  • There are two kinds of kernels used in firmwares - 2.4 and 2.6, use the wrong one and you could brick your device.
  • There are different types of builds - using a Mega build could brick my particular device.
  • If you try to reboot routers too quickly within the flashing phase, you could brick your router.
  • Trailed builds, are builds specific to a particular router. They do not have all the features or a regular build, but are critical to get off the original stock firmware. Use the wrong trailed build, and you could brick your router.

And everything you learnt above had caveats, which could also cause you to brick your router.

Anyway, after several days of researching, and figuring out what my priorities were, I decided to skip the DD-WRT in favor of a different sort of firmware called Tomato, and in particular a fork called TomatoUSB, that seemed most appropriate. I still had to upgrade to the DD-WRT trailed build to get off the stock firmware, but that was only a rest-stop on the upgrade path.

Next post, doing the actual upgrade.

My little Tablet problem

My Thrive had a problem - no, not the earlier one with the cracked screen, but a different sort of a problem.

About an year ago, I set up an inexpensive Terabyte RAID accessible on our home wireless network - a free cloud if you please. All my photos are on said cloud, and I had hoped to use my new Thrive to actually browse through and check my photos out in style. Part of the reason to get a tablet, was to consume my own media.

Here is where standards were supposed to help. My router was technically capable of sharing the Terabyte via either HTTP, FTP or most importantly SMB (essentially Windows Share). And my Tablet was supposed to be able to browse via SMB. But, try as I might, I just did not seem to work.

ASTRO File Manager
AndSMB Samba Client

I tried all the usual suspects ASTRO File Manager, AndSMB Samba Client, File Manager HD and ES File Manager. All of which had rave reviews, all talking about successful connections to other Windows machines.

File Manager HD
ES File Explorer

But none of them seemed to work. Out of character for me - I created new accounts on two Thrive Forums, to ask for help - no luck there either.

After three days of frustration, I began to realize something. Maybe the problem was not with the Thrive at all. Maybe, the problem was with the router, that was just unable to play nice with all SMB clients, including that on the Thrive.

Luckily, here is where my obsession for freedom began to pay off. My router is a Netgear 3500L. It is about the closest to a poster child for open hackable routers, that one can buy. A fact that Netgear actually advertises on the flier for the router itself. So I figured I'd flash my router, and hopefully make the newer version of SMB play nice with my Tablet.

Whether that worked is another story, but the moral of the current post is this - having freedom is awesome. It opens up possibilities and opportunities. It makes you focus on answers, not problems. And it is green too - who knows, I could have been tempted to buy a new router and chuck this one out, instead of trying to fix it.

My Toshiba Thrive's Screen Cracks

Sunday did not start well for my Thrive. I settled down with a cup of coffee to consume some video material, while using a soft cloth to gently wipe down the fingerprints on the screen. Halfway through the video watching my left hand, which was holding the tablet, started to ache. So I switched hands, when I noticed this hairline crack right under where I had just been holding it.

As I was saying, Sunday did not start well for me either.

We obviously went into a tizzy, trying to figure out what went wrong - did we drop it (no), did we crack it against something (no), was there a goblin in the house that goes about cracking LCD screens (no). Until the answer was fairly obvious, the glass cracked as I was holding the tablet one-handed and cleaning screen while watching a video.

Turns out, I was not the only case of this happening. Amazon has an eerily similar story, another dealing with a hairline crack and one with a peel-off LCD. Others have stories of shattered glass after a short drop. ThriveForums.org has this heroic tale of a dropped tablet and it's reincarnation.

Now here is my experience. I called up Toshiba on their customer support number (1-800-457-7777) to see if this would be covered by the standard warranty - No. They suggested I instead contact their out of warranty repair services. Turns out their starting quote for repairing the LCD is $354. Which is about $55 more than what I paid for the tablet.

In summation, the warranty does not cover it, and repairing it costs more than what I paid for the tablet. The obvious choice, I thought, was to kiss the warranty goodbye and do it myself. That is when it started to really stink.

NPD (National Parts Depot) is the parts supplier for Toshiba in the US. At the beginning of the year, they carried the replacement touchscreen and (4) sponges for $82 plus shipping. At some point, Toshiba stopped fulfilling orders for that part, and instead started to just sell the top case assembly for $180 plus shipping.

I get that LCD screens crack. I understand if it is too expensive for Toshiba to repair it for me. But when it feels like Toshiba systematically believes it needs to make money by making cheap parts scarce - it is time to stop encouraging such companies. Sorry guys, no more Toshiba purchases from me. I am just going to use the Thrive as-is and see how long it lasts, while buying exactly diddly-squat worth of accessories.

Thanks for leaving a really bad taste in the mouth.

Pre-installed crud on the Thrive

Now that I've had a bit of time to play with my new fondle-slab, it is time to delve a bit more into what seems to be an odd philosophy from Toshiba in putting together the Thrive. The tablet comes with a near-vanilla version of the Android Honeycomb 3.1 OS, with a few useful Toshiba customizations and utilities. Then there is a curious collection of trial-ware and general crud, topped off with a collection of basic Google mobile goodies. Very little thought seems to have gone into in this - almost as if Toshiba was trying to be recklessly indifferent to its customers.

Android HoneycombFirst the good news - full marks for minimal changes to the stock Honeycomb installation. Keeps the tablet zipping along without additional overhead while keeping the option open for future upgrades (Ice Cream Sandwich anyone?). That said, there aren't too many indications that Toshiba is going to upgrade, unlike Samsung or HTC.

There is then the matter of custom tools that Toshiba built for the occasion. They range from the very useful, like the Service Station and File Manager to the bug-ridden Media Player and the after-thoughts like the App Place and BookPlace™. The App Place is the strangest. It does not offer much more than the Android Marketplace, is not mandatory and yet is an app one cannot uninstall. Clearly as useful as the points system on Who's line is it anyway?.

If Toshiba's app collection is a puzzle, it's third party catalog is a disaster. Outside of the plugins for Adobe® AIR® and Flash, the rest are trial versions of tools that we probably have better, free alternates available for. To add insult to injury, one cannot uninstall them - not even when you buy the full version.

I get that there is an economic reason to include trial versions, but the inability to uninstall is little more than spite. If ever the argument was, “Hey, we think these are must-have apps, so try them out and buy them so we can a cut of the revenue”, there is no sign of it. Instead, the pitch now is, “I don't know or care if you like these apps, but because others have uninstalled them in the past, we are not gonna let you.”. Seems like a rather haphazard way of gaining supporters among your customers. Just try searching for Kaspersky+ Thrive and you can sense the frustration.

Dictating how you want others to use your device is a futile exercise - Apple gets away with it, because they can. Toshiba cannot. So whoever is making the final call on what to include and what not to, remember this - you are not Apple. Don't act like them.

Thriving with a Tablet

I got me a tablet. Or as Register prefers to call it, a fondle-slab.

This Groupon, got things rolling for me. The price point was close enough, that I could get into the world of tablets without the worry that I'd have a super-expensive paper weight if I figured the fondle-slab form factor was not for me.

First impressions, the Thrive is a great device. Feels a tad chunky coming out of the box, but on the flip side, the rubberized back feels very safe and the thickness allows it to be gripped well. One is not constantly worried that it is a matter of time before sweat on your palm will cause the tablet to slip.

Logging in with your Google account means that all of your data comes synchronized right away. All your contacts are in the contacts app, Gmail is up and running and the Photo viewer displays all your Picasa albums - all with no further configuration from you. I know this is true of all Android gadgets, but the effect is scary and giddy at the same time.

Final first impression - the screen. The 10.1 inch display packs in a resolution of 1280 by 800 pixels. The device is powered by the NVIDIA Tegra chip, withe graphics handled by a GeForce card. This graphics focused setup churns out crisp and smooth graphics, without a hint of hesitation. The resolution is so good, that looking at my made-for-web 600x400 crops from Picasa in full screen, made them look - ugly. The capacitive multi-touch screen is very responsive, making the user interface thus far, a real pleasure.

Evercube

Came across this pretty awesome piece of hardware - a well-built open source Network Accessible Storage (NAS) - called Evercube.

The design is open hardware, available under a Creative Commons Attribution license. And it looks good as well - a stainless steel 6-inch cube, housing five 2.5" hard drives - not the big drives but those smaller laptop ones.

Which makes it quiet enough to run in the living room.

But then it is expensive. So - maybe not the best use of the monies, but never hurts to know that there are open source options that look good.

Addictive fitness with a fitbit

When I first heard about Fitbit, it seemed like one of those fads that seemed to sweep across the public conscience, for a few ephemeral moments before the destined disappearing to obscurity. A “glorified pedometer” someone called it. And strictly speaking it is one. But it had one redeeming quality in its favor - it makes being healthy fun, addictive.

At it's heart, the Fitbit is a nifty device that uses a 3-dimensional motion sensor, which gives it a very accurate way to measure movement. The other piece of cool technology is it's base station. Using an ultra-low power 2.4 GHz ANT radio transceiver, the base station silently talks to any device that is within 15 feet to collect motion data and post it to the fitbit website.

Which is when the real magic begins.

The fitbit experience has nailed two things - calibration and presentation. Armed with nothing more than motion data, the fitbit is able to translate that into steps, and further into calories burned all with just the minimum physiological data about the wearer. While this might not rank really high on the “accuracy” scale, it is tremendously useful on the “it just works” scale.

Once it does these translations, it does an equally good job with presenting the information without making it too overwhelming. The fitbit itself has an embedded screen with a single button, which gives enough information to whet your appetite. The website furthers this thirst for knowledge by presenting, plotting, tagging and socially comparing the fitness data. In addition, the website also allows you to log food intake, activities and other vital statistics - stuff the fitbit cannot dream of measuring.

Activity Tracker

That is me above - a relatively sedentary day, with frenzied activity getting to and from meeting rooms; and a tennis game to round the evening.

Fitbit takes the same motion tracker technology and does something else with it. By using a provided sleeve you can wear the tracker on your arm while you sleep and it keeps track of how many times you toss and turn to determine how restful a sleep you have had. Again, not the most accurate - not every toss and turn is bad and not every time you wake up do you have to move. But good enough to serve a purpose.

Activity Tracker
5,000 Steps in a Day10,000 Steps in a Day

But in the end, what makes fitbit really stick, is the nice balance it strikes in being fun yet earnest. It does not come across as that chiseled guy in the gym who seems to speak jargon no one else comprehends, or irreverent like Groupon which may be good for selling baubles but is not the best pose to strike when you are urging to get someone to be healthy.

Yet it has elements of both; making me, for the first time, want to challenge myself to be more active.

Cell phones & Cancer (infographic)

It was a strange feeling when I heard about CNN's breaking news that cell phones caused cancer. I had long known the need for caution, when it came to microwave radiation. But singling out the low power of a mobile phone in this age of electro-magnetic saturation seemed too fantastic.

Yet, the first few paragraphs in the CNN article seemed to portray it as a done deal. As if the most damning of evidence had quietly piled up. The strangest part was that there was no new studies being cited.

It took a little searching around and spending some time with comments on sites, that are not CNN, for things to start making sense. There were no new studies. Instead, based on the existing data (and wishy-washy footnotes that had been known for years) WHO had decided to formally include cell phone emitted EM radiation in the "needs confirmation" category. Yes, lead is in that category, but that is lead. Not inorganic lead compounds. Those are in another category which includes those items that actually do cause cancer.

The CNN article made it seem like cell phone radiation belonged to that other list.

Nevertheless, at the suggestion of a colleague, I figured the best way to reasearch this would be to put an infographic together. Here it is, on the left. It quickly introduces the EM spectrum and the ionizing vs non-ionizing nature of different radiation. And how the amount of energy emitted by a cell phone is limited. Before citing the tremendous body of research that has found no clear indication of a linkage between mobile phones and cancer. And finally a quick review of the grouping system used by the WHO and why Group 2B does not mean the sky is falling down.

This is one of the longest infographic I have made. Click for the full size.

GDesk on the Nokia 5800: more details

GDesk is a work in progress. This is painfully obvious when you begin trying to configure or edit the existing UI.

Toggling the "edit" mode happens via the Design menu item. Once you toggle the edit mode, you are now able to modify the content and placement of the various icons on the interface.

What you can do though is severely limited. The first, and most glaring problem is the lack of an undo option. This puts you in a strangely tentative mode while editing. To add to it, there is no easy way to manage the z-index. So if you have overlapping elements, it seems like what ends up on top is something you have no control over. A couple of slips of the stylus and the only option is to Discard Changes and start right over. Saving frequently is probably the only approach to successfully making big changes.

That said, there is still a lot you can do. You can set up icons and links, change their sizes and use many of the active elements supplied by GDesk.

Editing is not the only thing that is half-baked. After using the interface for a while, it feels like I am ready to get back to the original UI. There are several reasons for that.

  • First and most importantly, this is not a complete replacement of the UI. All applications still look exactly the same as under the original UI. This is merely an alternate home screen.
  • While on the subjects of home screens, GDesk does not really replace it. Instead, it is full screen program, configured to jump in everytime you go to the home screen.
  • Most elements on the UI are not configurable. It does seem to have a title-bar but no way to edit it's properties.
  • GDesk is limited in terms of how much you can talk to the underlying phone, and how much the phone can talk to you. Notification is the key gap here. Each notification capability needs to be programmed separately, and right now the only notifications programmed are the SMS and battery. This means you cannot see if you have missed calls, emails or other alerts.
  • The other capability I missed was the ability to choose the profile directly. This meant 5 or 6 taps to switch to and from silent; instead of the usual 2.

Overall GDesk is more a way to get some good eye candy and not really a replacement UI. But again, this was little more than a beta, and something Nokia never thought to run with.

Capture Camera Clip: on Kickstarter

I guess I joined the bandwagon. After all the case is so compelling. The video above is a great introduction.

tl;ds

The Capture Camera Clip System is a machined doodad that grabs onto belts and backpack straps that allows cameras to be clipped onto it. Using the tripod mount, the clip looks and sounds like a solution that can finally take on the problem of the swinging, dangling SLR.

This, also was my first attempt at backing something on the site Kickstarter. If you have not heard of the site yet, it is a creative way to fund projects. Everyone gets to be a venture capitalist, for a fixed reward of course, and not a direct equity stake. Nevertheless it has spawned several awesome projects including the TikTok+LunaTik Multi-Touch Watch Kit, Diaspora and GoPano, in addition to a ton of movies and documentaries.

Swapping the battery on an iAudio X5

The iAudio X5 running a Rockbox build has been my default music player practically forever. Even after a forgetful incident while deplaning a Lufthansa flight caused me to lose my first purchase of the X5L, my replacement was a 60 gig X5. It is bulky, clunky and rather plain but has everything else I needed in my player. Great hardware, FM radio, Aluminium chassis (survived two falls), good battery-life, wonderful sound and finally hackable hardware.

When it's battery finally started to give way, the portable player became a PMP at home, and when the input voltage fell to 1.8v it was time to change the battery. Thanks to this thread, I had enough of a peek into the internals of the player and the name of a replacement battery. RadioShack has the Dantona 3.7V/1100mAh Li-ion PDA Battery for Cowon/iAudio (Model: PDA-203LI | Catalog #: 55027810) available online for $25. If you find a local store that does "Ship to Store" you could get it delivered for free. This replacement has slightly lower capacity than the original, but there hasn't been much success in finding a battery with higher capacity that fits.

Dis Assembled

Replacing the battery is not that difficult. My only hesitation in starting with it was that I did not have a solder iron. And I was not going to buy an iron plus lead for what could be just two joins. I figured I could do a quick and dirty splice instead. The detailed steps are given below, with the numbers in the text referring to the numbers on the image.

You need a couple of small screwdrivers [1], one with a flat and the other with a Phillips head. I used a set that came as part of a spectacles repair kit. You also need to get the batteries [2] before you begin.

To get the back of the player [3] off, using the Phillips driver to unscrew the four screws holding it on. The first thing you will see is the hard-disk [4] and a tape holding it down along the top. There are also a couple of wires running down the sides as well. Carefully separate the wires, undo the tape and flick the top of the hard-disk to get it off. The hard-disk is connected to the body via a cable, which you should try your best to never damage.

Some versions, have a rubber cushion [5] between the hard-disk and the battery, use your flat screwdriver to gently ease it out. This will expose the battery [6] allowing you to pull it out and show the two wires connecting it to the circuit board.

Because I was not going to solder the battery on, the other approach was to cut the existing battery, stripping away the insulation for both the existing wires and the new battery and splicing them together. Which was when I realized I did not even have a decent insulation tape, so regular tape had to do instead.

Couple of tips. The wires are multi-strand. This is both good and back. Good, because it makes splicing that much easier. Bad because any weakness you introduce while stripping the insulation may cause the strands to break and short the board itself. Make sure you blow the board clean before re-assembly.

That is it. Repeat the steps in reverse to put everything together. In my case this left me with a player that is once again portable. And it still as great a media player.

What is behind my Kindle?


I had gotten used to having a couple of cryptic symbols on the back of my electronic devices. But when I recently got my new Kindle 3, there were two whole rows of ant-like hieroglyphics. What exactly was my Kindle telling me? Naturally, I had to go figure out what they were.

The symbols were so faint that multiple rounds of sharpening were required.
Click image for more detail.

Starting from the left on the top row, G.O.S.T. is the part of the federal regulation standard in Russia. Certificate of Conformity in GOST R system affirms that the goods delivered in Russia, and/or production line where they were manufactured, conform to the Russian Safety Standards. Haven't been able to figure out why the certification still says PCT, and I suspect the pages that may hold clues to that, on the Federal standards site are not in English.

Edit: As pointed out by anonymous below, that is not PCT but RST (in Cryllic alphabet), which stands for Russian Standard.

Anatel is the Brazilian regulatory authority, that has evolving and stringent guidelines around standards that are to be followed by all electronic devices to be sold in Brazil. The different thing about Brazil's standards authority is that it mandates testing in Brazil and does not accept results from external testing.

This squiggly guy took a little effort in tracing down. Turns out this is the National Communications Commission of Taiwan. Established in 2006, it is responsible for regulating telecommunications, information and broadcasting sectors.

KCC is the next C-infused icon on the back of my Kindle. KCC stands for Korea Communications Commission, which as you can surmise is regulatory and policy making body for Korea. KCC certification covers three schemes, namely EMC, Radio, and Telecom. As as it turns out they may be getting a new icon shortly.

Other than looking like part of a circuit diagram, this logo refers to Japan's telecom and radio certification authority. Certification is required before the device can be used in the country. Certification is no longer issued only by the government affiliated JATE, but also by private certification bodies. Testing to Japan's technical requirements may be conducted by many laboratories around the world.

This unnamed numerical double arrow took a while. Apparently this is a regulatory requirement for China RoHS (Restriction of Hazardous Substances). Apparently anyone shipping a product to China, that contains hazardous substances, should also specify how long the product can be used before the hazardous products, umm, leak out. In other words, Kindle 3 is designed to be obsolete in 20 years. Note to self: do not plan on bequeathing books to grandchildren. Bequeath book collection to enemies.

I am not quite sure why C is such a favored letter in these telecom regulatory insignia. Nevertheless, the next authority with three of the letter C in their logo belong to China. Effective 2003, the China Compulsory Certification mark is required for a wide range of manufactured products before being exported to or sold in the Peoples Republic of China market.

FCC - Federal Communications Commission is the US Government org that regulates devices which use wireless antennae. Without FCC approval no devices can be sold. You can search details of any device by using the FCC ID. The ID for Kindle 3 has the following parts:
Grantee Code: "X7N"
Product Code: "-0610"
The FCC submission, beyond its regulatory requirements is an interesting collection of technical details of the device, including its SAR.

UL is shortened from Underwriter Laboratories Inc. UL Laboratory is a non-governmental organization in the field of security test and appraisal. It is independent, non-profit and professional institution that performs the test for the public security. UL is mainly concerned with production attestation and business security certification. The purpose of UL is to ensure products are safe for public use.

The next icon takes a break from National Telecom regulatory authorities. WEEE is a EU regulation that imposes the responsibility for the disposal of waste electrical and electronic equipment on the manufacturers of such equipment. Also, the companies are compelled to use the collected waste in an ecologically-friendly manner, either by ecological disposal or by reuse/refurbishment of the collected WEEE.

The Normas Oficiales Mexicanas (NOM) Mark is a mandatory consumer protection program requiring that certain products such as cellular devices be certified before they can be sold in Mexico. NOM safety approval in Mexico requires in-country testing in order to create an appropriate safety report accepted by the Mexican safety agency NYCE.

ACMA is the compliance authority for Australia. EMC and radio communications compliance is labeled using the C-Tick mark. The compliance label indicates that the product complies with the applicable standard and establishes a traceable link between the equipment and the manufacturer, importer or their agent responsible for compliance and for placing it on the Australian market.

The CE Mark is a EU requirement that states that the product is assessed before being placed on the market and meets EU safety, health and environmental protection requirements. Kindle is categorized as a radio device and therefore needs to comply with requirements of the R&TTE directive

Last but not the least. And I really mean it this time. Of all the symbols, this is among the most cryptic, and actually needs you to do something - not use the device in Switzerland. This is called a class identifier, which is a graphical symbol intended to indicate that operation of the radiocommunications equipment to which it is affixed is subject to restrictions.

So kids, what have we learned so far? Use the Kindle 3 now, before lead starts leaking out in 20 years (pity future generations that can never discover books in the attic). Regulations do not really help a consumer (who in their right minds would try to do what I did above). Our design for the dump philosophy is alive and well. And finally, you cannot use your Kindle while skiing in the Alps.
