Samsung Manager YH-820 is a manager for the Samsung YH-820 digital audio player (an maybe others).

Samsung Manager YH-820 manages song for the digital audio player from Samsung.

The program aims to be as more user friendly as possible, using HAL and Dbus for player detection and provides a gobject based library that, eventually, may be integrated with a music player (for example Rhythmbox).

In the spirit of "release early, release often", it lacks song removing. Please report any bug and backup your player, a new release will follow soon.

UFFS is an ultra low cost flash file system for embedded system.
UFFS is a NAND flash file system designed for embedded system, it performs some unique and advanced features:
Low cost:
For NAND flash with 512 page size:
NAND flash | Total Blocks | Buffers/Caches | Total RAM cost
128M | 8192 | 40/30 | 164K
32M | 2048 | 40/30 | 68K
16M | 1024 | 10/10 | 26K
Tree Nodes: 16 * toatl_blocks
Page Buffers: page_size(512) * buffers (10 ~ pages_per_block)
Block info caches: (14 * pages_per_block) * block_info_caches ( 5 ~ 20)
Total Memory usage = Tree Nodes + Page Buffers + Block info caches + Others(1~2K)
For NAND flash with 2K page size:
NAND flash | Total Blocks | Buffers/Caches | Total RAM cost
512M | 8192 | 40/30 | 180K
128M | 512 | 40/30 | 70K
Tree Nodes: 16 * toatl_blocks
Page Buffers: page_size(2048) * buffers (10 ~ pages_per_block)
Block info caches: (14 * pages_per_block) * block_info_caches ( 5 ~ 20)
Total Memory usage = Tree Nodes + Page Buffers + Block info caches + Others(1~2K)
Fast booting
UFFS read only one spare area for each NAND flash block to build up the in-memory nodes tree. Typically, UFFS needs less then 1 second to mount a full loaded 128 Mbytes NAND flash.
Superb Reliability
Guaranteed integrity across unexpected power losses.
Bad-block tolerant, ECC enable and ware-leveling
Nothing new for flash file system, but UFFS implements these in a simple yet effective way.
No garbage collection needed for UFFS
UFFS collect the dirty blocks on the fly, no garbage collection needed.
Support direct flash interface, no operating system needed
UFFS can be build on top of direct flash interface,easy to port to any embedded system.
Fully tested
UFFS is fully tested on PC (via UFFS PC emulator). Moreover, UFFS is not just proof-of-concept but has been successfully used in real world product for tens of thousands of copies.
What UFFS "IS", "IS NOT" ?
UFFS is not a Linux kernel module.
UFFS is not running in a separated thread rather than application.
UFFS is a library to be linked with your embedded application.
UFFS should be used when JFFS/YAFFS cant be used (because of the insufficient of memory)
UFFS is not the substitute of JFFS or YAFFS.
Why UFFS ?
- Hardware resource is limited (typically 64~512K RAM), but need a reliable flash file system
- JFFS/JFFS2 sucks (useless without Linux/MTD, also memory monster)
- YAFFS/YAFFS2 is excellent, but still consumes too much memory
- Others ? ... not available... (open source of course)
Enhancements:
- Support large page size, e.g. 1K, 2K, support all Samsung NAND flash.

BitPim is a program that allows you to view and manipulate data on many CDMA phones from LG, Samsung, Sanyo and other manufacturers.

BitPim includes the PhoneBook, Calendar, WallPapers, RingTones (functionality varies by phone) and the Filesystem for most Qualcomm CDMA chipset based phones.

You need a cell phone that BitPim can talk to (details).

You will need a cable that plugs into your computer and into the cellphone. The page for your cell phone lists details of the cables.

If you use Windows, a driver is required for your cable. The driver should be supplied by the supplier/manufacturer of the cable. Drivers may also be available online from the manufacturer of the cable or the phone. The "section" of the help pages for your phone may have pointers to these drivers. Mac OS X and most recent Linux distributions include the drivers, if required.

BitPim is a Python-based app that allows you to view and manipulate data on LG VX4400/VX6000 as well as many Sanyo Sprint cell phones. This includes the PhoneBook, Calendar, WallPapers, RingTones (functionality varies by phone), and the embedded Filesystem for most Qualcomm CDMA chipset-based phones (expert users).

Note: You should to use the test releases if you have any phone other than the LG VX4400, with the LG VX4400 you should use this version. Also, straight USB cables for the LG VX4400 phone WILL result in errors.
Supported phones:

- Audiovox CDM-8900
- LG-VX4400
- LG-VX4500
- LG-VX6000
- Sanyo SCP-4900
- Sanyo SCP-5300
- Sanyo SCP-5500
- Sanyo SCP-7200
- Other CDMA phones

RT-Thread is a real-time operating system. It is designed specifically for small memory footprint platforms. The kernel supports the tranditional RTOS services, such as multiple threads, semaphores, mutexes, event flags, mailboxes, etc.
RT-Thread project also provides a C-expression interpreter shell, from which a programmer can access kernel variables and invoke system functions.
Main features:
Kernel Object System
- There is a kernel object system, which can access and manage all of the kernel objects. Kernel objects include most of the facilities in the kernel, for example, thread, semaphore etc. Kernel objects can be static objects, whose memory is allocated in compiling. It can be dynamic objects as well, whose memory is allocated from system heaps in runtime. Through the kernel object system, RT-Thread operating system can be independent from the memory management system and greatly enhance the scalability of the system.
Multi-Task/Thread Scheduling
- RT-Thread operating system supports multi-task systems, which are based on thread scheduling. The scheduling algorithm used in RT-Thread operating system is a full preemptive priority-based scheduling algorithm. It supports 256 priority levels, in which 0 is the highest and 255 the lowest. The 255th priority is used for idle thread. The scheduling algorithm also supports threads running at same priority level. The shared time-slice round-robin scheduling is used for this case. The time of scheduler to determine the next highest ready thread is determinant. The number of threads in the system is unlimited, only related with RAM.
Synchronization Mechanisms
- RT-Thread operating system supports the traditional semaphore and mutex. Mutex objects use inherited priority to prevent priority reversion. The semaphore release action is safe for interrupt service routine. Moreover, the block queue for thread to obtain semaphore or mutex can be sorted by priority or FIFO.
Inter-Thread Communication
- RT-Thread operating systems supports event/fast event, mail box and message queue. The event mechanism is used to awake a thead by setting one or more corresponding bit of a binary number when an event ocurs. The fast event supports event thread queue. Once a one bit event occurs, the corresponding blocked thread can be found out timing accurately, then will be waked up. In mailbox, a mail length is fixed to 4 byte, which is more effective than message queue. The send action for communication facilities is also safe for interrupt service routine.
Clock and Timer
- In default, the system uses clock tick to implement shared time-slice scheduling. The timing sensitivity of thread is implemented by timers. The timer can be set as one-shot or periodic timeout.
Memory Management
- RT-Thread operating system supports two types memory management: static memory pool management and dynamic memory heap management. The time to allocate a memory block from the memory pool is determinant and when the memory pool is empty, the allocated thread can be blocked (or immediately return, or waiting for sometime to return, which are determined by a timeout parameter). When other thread releases memory blocks to this memory pool, the blocked thread is wake up.
Enhancements:
- More porting was done to Samsung S3C44b0 CPU, AMTEL AT91SAM7S64, Nintendo DS, and Intel i386.

Free60 Gentoo LiveCD Xenon is a liveCD for Linux on the Xbox 360. It is based on the experimental gentoo liveCD that can be found here:
http://gentoo.mirrors.pair.com/experimental/ppc64/livecd/
It has a few changes to boot on the Xbox 360 (codename xenon).
How does it work ?
Burn gentoo-livecd-xenon-beta-v2.iso. Upload the cdreader binary via serial, or use the new king kong patcher with built-in readcd code, this will open the dvd tray. Put the gentoo-livecd-xenon-beta CD in the drive. cdreader will automatically start the xell bootloader located at lba 0x20 on this cd and boot the Linux Kernel.
Thanks to stonersmurf for the compilation of the liveCD.
