Robotics TOOLBOX
The Toolbox provides many functions that are useful in robotics including such things as
kinematics, dynamics, and trajectory generation. The Toolbox is useful for simulation as
well as analyzing results from experiments with real robots.
Have fun with the toolbox. It is self-explanatory and very (robotics) user friendly...see the robot.pdf
The TMS320C64x™ DSPs (including the TMS320DM642 device) are the highest-performance fixed-point
DSP generation in the TMS320C6000™ DSP platform. The TMS320DM642 (DM642) device is based on
the second-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW)
architecture (VelociTI.2™ ) developed by Texas Instruments (TI), making these DSPs an excellent choice
for digital media applications. The C64x™ is a code-compatible member of the C6000™ DSP platform.
You know the rudiments of the SQL query language, yet you feel you aren t taking full advantage of SQL s expressive power. You d like to learn how to do more work with SQL inside the database before pushing data across the network to your applications. You d like to take your SQL skills to the next level.

FIST可堆疊文件系統，linux文件系統修改相關的開源軟件，使得對linux文件系統功能的改進很簡單了
The FiST (File System Translator) system combines two methods to solve the above problems in a novel way: a set of stackable file system templates for each operating system, and a high-level language that can describe stackable file systems in a cross-platform portable fashion. Using FiST, stackable file systems need only be described once. FiST s code generation tool, fistgen, compiles a single file system description into loadable kernel modules for several operating systems (currently Solaris, Linux, and FreeBSD). The project demonstrates that with FiST, code size and development time are reduced significantly, while imposing a small performance overhead of only 1-2％. These benefits are achieved, as well as portability, without changing existing operating systems or file system.
Ink Blotting
One method for escaping from a maze is via ‘ink-blotting’. In this method your starting square
is marked with the number ‘1’. All free, valid squares north, south, east and west around the
number ‘1‘ are marked with a number ‘2’. In the next step, all free, valid squares around the two
are marked with a ‘3’ and the process is repeated iteratively until :
The exit is found (a free square other than the starting position is reached on the very edge
of the maze), or,
No more free squares are available, and hence no exit is possible.
兩種解決方案 Richard just finished building his new house. Now the only thing the house misses is a cute little wooden fence. He had no idea how to make a wooden fence, so he decided to order one. Somehow he got his hands on the ACME Fence Catalogue 2002, the ultimate resource on cute little wooden fences. After reading its preface he already knew, what makes a little wooden fence cute.
A wooden fence consists of N wooden planks, placed vertically in a row next to each other. A fence looks cute if and only if the following conditions are met:
?The planks have different lengths, namely 1, 2, . . . , N plank length units.
?Each plank with two neighbors is either larger than each of its neighbors or smaller than each of them. (Note that this makes the top of the fence alternately rise and fall.)
To use the ATLTrace tool:
Debug an MFC or ATL project select Start from the Debug menu.
Select MFC/ATL Trace Tool in the Tools menu.
Expand the tree control list in the Trace List window. Here you will see the running application, any modules within that application, and the trace categories for each module.
Customize, for each process, module, and category, which information is displayed in the output window. The Trace level control in the Process group is related to the ATLTRACE2 level only those ATLTRACE2 messages with a level equal to or greater than the setting in the Trace level control will be displayed in the output window.
Select Apply to put your settings into effect.
You can save your settings, and load them the next time you debug the application use the Save and Load buttons.
