Puzzlotto has been about as hidden as the lemurs you can see in the screenshot over there, for some reason — the concept isn’t real easy to grasp, and if you just stumbled across the “game” in the App Store, odds are that you’d think you had $5 stolen from you. But there is a weird story hidden here, both literally and figuratively. The game itself was designed by people like Mike Lee of Delicious Monster and David Lanham of Iconfactory, but the screen you’re presented with on loading the game doesn’t seem anything like the Mac software those guys are known for — there’s just a picture of a forest, and a few eyes that you can touch to make lemurs and other creatures pop out. I would tell you more, but I haven’t actually figured it out yet — there’s a “fosa” that will scare away any lemurs or butterflies you’ve summoned, and I know that the butterflies are basically a progress meter, but other than that I have no idea.
But Puzzlotto isn’t just that perplexing app — it’s been dubbed “fundware” by Lee, and 10% of the proceeds from the game will go to the Madagascar Fauna Group to support the habitats of lemurs, fosas, and butterflies. And it’s actually a puzzle to be solved, with a cash prize — if you can be the first to figure out the “puzzle” behind Puzzlotto, United Lemur will give you a cash prize out of their prize pool, currently at $5000, and growing every day for 31 days. If no one claims the prize at the end of the 30 days, all the money will go to charity, project over. You can follow updates on their Twitter — it sounds like no one’s claimed any prizes yet, which is no surprise — if there are any clues in the app, they’re very, very hard to find. United Lemur claims that there is a game in there (and that it is worth the $5 entry fee), but so far, all players have found is a few screens of the weird lemur puzzle.
But it is a different kind of game — a cash prize handed out by a flabbergastingly tough puzzle disguised as an App Store game, all designed to benefit a charity. Lee says on his blog that they wanted to make a game where players couldn’t cheat by telling each other the answer, but maybe they didn’t realize that part of the fun of Myst is sharing the strategy with other players. And if you don’t want to shell out the $5 on Lee’s word, it might be fun to just wait until the solution gets posted somewhere anyway. Have you solved any part of Puzzlotto yet?

The SD memory cards known as the “Secure Digital” first began as miniature cards. Afterwards the new and advanced form of the SD memory card SDIO “Secure Digital Input/output” was introduced into the market. The SDA “Secure Digital Association” included new features and technology to the SD memory cards. The SDA included new varieties of card functions. These new card functions included wireless “Local Area Network LAN” devices, cell phones, GPS receiver, digital video camera etc. The memory card readers that were used in the Secure Digital devices connected to the Universal Serial Bus (USB). The Windows Operating System detects and manages the SD (Secure Digital) memory cards through the driver called the (USB) Universal Serial Bus mass storage. The (SD) Secure Digital host controllers are supported by the Operating System. The Operating System connects the host controller SD to the Peripheral Component Interconnect (PCI) bus. When the SD-host controller is detected by the operating system, the “SD Secure Digital bus driver” is loaded by the operating system OS. When the SD card is inserted by the user, the windows Operating system loads two drivers the “Storage mini-port” and the “SD Secure Digital Storage Class”. These two drivers are loaded on top of “Bus driver” by the Windows Operating System. On the other hand if the SD memory card of a different function like the wireless Local Area Network (LAN) or the Global Positioning System is inserted by the user, then the Windows Operating System loads the driver that is supplied by the vendor. It is necessary that both the vendor supplied and the native drivers in the (SD) Secure Digital stack communicate with “Secure Digital Bus”. The device drivers call the routines to communication with the “Secure Digital Bus”. These routines are called in the static “Secure Digital Bus library”. When the SD Secure Digital drivers compile, it is necessary that they link to the “Secure Digital SD Bus library”. There are some limitations for the SD device drivers. The “Host Controller Register” is not directly accessible by the Secure Digital device drivers.
The SD device drivers call the routines of “Secure Digital Library”. Then the Secure Digital Library forwards the Secure Digital commands to “Host Controller”. Music can be stored in the Flash Memory card and it is most advantageous than storing it in the Hard drives. The SD flash memory cards consume less power and are more portable. The SD flash cards also have resistance to shocks. The SD card facilities its users and they can easily record the data to their personal liking like music, pictures. The users can easily carry and move the data with ease and comfort. The SD memory card has the technology to fulfill the requirements of the future networked society. The tiny SD memory card provides many advantages to their users. These memory cards are highly compatible and they can link to different digital equipments. Because of the compatibility of the SD memory cards, their usage is more likely to expand even more in the future. The SD card has now become a standard of memory cards that are used for digital connectivity. In the near by future, the SD cards will be universally accessible to more wide array of Multimedia data. The size of the SD memory card is approximately 24mm x 32mm x 2.1mm. The design of the SD card is very compact and slim. Therefore, they are easy to handle and the user can easily transfer the data.
The devices that are compatible with SD card can play video clips & music with the help of “decoder software”. The DVD & CD players use “drive mechanism” while the SD memory cards do not require “drive mechanism” to play the video clips. So, this gives the product designers more freedom and they can be more creative and innovative. The other popular form of the SD memory card is the miniSD memory card. The size of the mini-SD card is approximately 20mm x 21.5mm x 1.4mm. The miniSD card is smaller in size than the SD card.
The SD memory cards have different recording capacitates, their capacity reaches up to 8GB. The large capacity helps to store the High quality videos. The demand for high capacity SD cards with fast data transfer speed has increased because of the increased digital content range. The SD cards also have the technology of “Copyright Protection”. This “Copyright Protection” technology enables new distribution system. This provides safety and security to the illegal copying of the data.The SD card has built in technology called the Key Revocation. The SD memory card has “Control Circuit”, which allows to read & write the after the detection of the external devices. The data is written and read within the “protection area” of the card. The authentication among the digital devices has to be enabled so that the SD card could be accessed.

SDelete is a free program from Microsoft’s TechNet Sysinternals collection. It runs from the command line, and can be used to wipe drives, wipe files, or wipe free space.
Time Needed: Varies; from a few minutes to several hours, depending upon size and speed of drive and computer
Software: TechNet Sysinternal’s SDelete
Available from http://technet.microsoft.com
Media: Can be run from Windows desktop
1. Download SDelete.
2. Extract the contents of the compressed file.
3. Copy sdelete.exe to c:\windows\system32\ (this will enable you to run it from any location)
4. Open a command prompt session with Administrator rights.
5. To wipe all files on drive X: and its subdirectories and to wipe free space, enter Sdelete -p 2 –s -z X:\*.* (to see all command-line switches, enter Sdelete with no options)
6. Wait; the program displays status messages as it runs. When the program is finished, you can reuse or dispose of the drive.
We used demo versions of two popular data recovery programs to evaluate some of the disk wiping programs discussed in this article. To determine whether a typical data recovery program could recover files on a SD card wipe with Roadkil’s DiskWipe, we first of all formatted the card using a card reader. Ontrack’s EasyRecovery Data Recovery (available from http://www.ontrack.com) had no difficulty finding folders and files to retrieve.
However, when we used DiskWipe to wipe the drive using a one-pass blank disk (zero fill) operation, EasyRecovery DataRecovery was unable to find the file system, let alone any files or folders.
After reformatting the card, taking a few photos, and deleting the photos, EasyRecovery Data Recovery was able to find the new photos, but the contents of the card before running WipeDisk were unrecoverable.
To evaluate SDelete, we used SDelete to wipe all of the files on a hard disk, but omitted the –z switch; when –z is not used, SDelete deletes files and renames them, but does not clear free space. To determine what might be visible, we used a demo version of Disk Doctors NTFS Data Recovery software, available from http://www.diskdoctors.net.
Disk Doctors were able to locate the deleted folder and Outlook Express message folders, but SDelete had renamed them from their original names and DBX extensions (Outlook Express message folders). If you use SDelete, it’s very important that you take time to use the –z switch to clear free space on the disk (once a file is deleted, the space it occupies is free space).
We also used Disk Doctors to evaluate the effectiveness of a freeware program called Eraser, which can delete and overwrite files and folders from the right-click menu. We created a documents folder with a subfolder called Figures and used Eraser to overwrite the folder and subfolder using its default settings.
Disk Doctors was able to locate the folders, but the contents are files with garbage names and are zero bytes in size – except for leftover word processing temporary files (files that begin with $). These filenames were not changed, which could enable a snooper to figure out the names of the files in the folder – although the files themselves were destroyed. By using more overwrites or different methods available with Eraser, a more thorough wiping may be possible.
We’ve highlighted a variety of free ways to protect data on castoff drives from being retrieved. As you can see, your best bet is to overwrite data directly, but you also might want to consider using a program such as SDelete to scramble filenames first and then use a disk wiper such as Eraser or WipeDisk to finish the job.
Use demo versions of data recovery programs such as Ontrack Easy Recovery Data Recovery, Disk Doctors Data Recovery (various editions for NTFS, FAT, and flash media), and others to evaluate the effectiveness of your data wiping procedures. Remember, the full versions of these and other data recovery programs can save your data if you accidentally format or partition a disk because, until the data is overwritten, it’s still there.
