We figured it wouldn’t be long before someone figured out how to remove the ads from the ‘Special Offers’ versions of the Amazon Kindle hardware. There are two things that made this obvious to us, the huge flaw that lets code be easily run as root, and the MP3 tag forming that makes it possible to unlock the device.

[Pat Hartl] knows his way around a *nix shell, so once he gained SSH access to the device he started a search for the ad images that make up the special offers feature. He found them in a few different places, making backups of the files in an alternate location, then removing them with some simple commands. He even rolled the process into a one-click installer like the Jailbreak package. It makes us wonder if Amazon has a way to tell if your device is not longer pulling down content for these offers?

At risk of sounding preachy, Amazon does offer this hardware without ads for a one-time fee. Circumventing the unobtrusive ads may lead to higher hardware prices in the future, and [Pat] mentions that. He pulled off this hack to show the holes in Amazon’s security, and hitting them in the pocketbook is a powerful way to do it.

Amazon’s new tablet reader, the Kindle Fire has been rooted. Early this morning [Death2All110] posted the steps he took to gain root access to his device (which is so fresh out of the box it still smells new). The heavy lifting is done by a package called SuperOneClick which aims to root all manner of phones and devices running Android.

There’s a bit more than the one click necessary, but not by much. Using the Android Developer Bridge in conjunction with the SDK you need to put in a value that will be recognized as the VID. From there, turn on the ability to install apps from unknown developers, re-enumerate the device on your PC and run the one-click package.

What can you do with this? Well, it completely opens up the Android OS so that you can bend it to your will. We haven’t seen any demonstrations yet, but it should be even better than what we saw done with the Sony PRS-T1.

Having read books on a Palm device for years we were excited when Amazon came up with the Kindle. Our problem is that if you’re going to carry around a portable device it should do a whole lot more than just display text from a few books. [Jesse Vincent] managed to get Ubuntu 9.04 Jaunty Jackalope running on the Kindle 2. This opens up endless possibilities to run whatever you want on this hardware.

The new functionality was presented in a talk at OSCON 2009. Be warned, [Jesse] has a very high geeky-hacker level. Make sure you have a tech dictionary and Google at the ready when you watch the video embedded after the break. His talk starts at about two minutes in and runs for five minutes total.

The people at iFixit have shown that they’re still on top of their game by tearing down the new Kindle 2 eBook reader. The main processor is a 532MHz ARM-11 from Freescale. Interestly, there isn’t any significant circuitry behind the large keyboard; it seems its existence is just to hide the battery.

Bittorrent is a great distribution method for large files, but its heavy bandwidth usage can be disruptive to both work and home networks. [Brett O'Connor] has decided to push all of his torrenting activity into the cloud. Amazon’s EC2 service lets you run any number of Amazon Machine Images (AMI, virtual machines) on top of their hardware. You pay for processing time and data transferred. [Brett] put together a guide for building your own seedbox on the service. First, you set up the Security Group, the firewall for the machine. Next, you specify what AMI you want to use. In this example, it’s a community build of Ubuntu. Once you have your SSH keypair, you can start the instance and install Apache, PHP, and MySQL. TorrentFlux is the web frontend for bittorrent in this case. It manages all the torrents and you just need to click download when you want to grab the completed file.

Even if you don’t plan on setting up a seedbox, the post is a straightforward example of how-to get started with EC2. He’s not sure what the cost will be; the current estimate is ~$30/mo.

For those willing to build machines themselves, there are several NAS focused distributions available. FreeNAS is based on FreeBSD and takes up less than 32MB even though it has a full featured web interface. Openfiler can be used for building full fledged NAS/SAN appliances. It can be deployed on bare metal or as a virtual machine and 2.3 has new features like bonding multiple NICs. CryptoNAS is a liveCD that helps you build a user friendly NAS device with full hard disk encryption.

Many consumer NAS devices have chosen to run Linux. This makes them good hacking targets for adding new functionality and we’ve covered many of them in the past. The Linksys NSLU2 “slug” has been very popular. Buffalo has sold many different devices: the Kurobox, Linkstation, and Terastation have a dedicated modification community. We’ve got a LaCie Ethernet Disk mini unopened in our office that was initially purchased because we knew they could be hacked. NAS-Central has a list of many of the other online communities dedicated to NAS devices.

Not that excited about administrating one more Linux box? When Apple released the Time Capsule earlier in the year it introduced the world to high capacity storage that “just works”. Although not exactly server grade, it brought the idea of regular backups to the home user. 1TB is nice, but it’s not upgradeable or easily replaceable; look to the Drobo for that. Drobo has built a fan base by making storage management easy for anyone. Just throw your commodity drives into the box and you’re ready to go. Unfortunately, turning it into a NAS is a $200 addition. They’ve published an SDK, so you should see new applications coming for it soon.

All of these options are just for in house serving, but none of them are true backup solutions since your data still goes away when your house burns down. A couple years ago, [Jeremy Zawodny] looked into moving his backup servers to Amazon’s S3 and compiled a list of tools that work with the service. Jungle Disk is probably the most user friendly. It’s multiplatform and mounts as a local disk. There’s an add-in for Windows Home Server too. If you’re looking to set up a simple personal backup system, we highly recommend [jwz]‘s advice for regular backups.

That’s a fairly thorough rundown of hacker friendly backup options, but we want to know what you use. How do you store, serve, and protect your data? What custom features have you added to commercial NAS devices?
