10分钟学会SQl第三版 Sams Teach Yourself SQL in 10 Minutes has established itself as the gold standard for introductory SQL books, offering a fast-paced accessible tutorial to the major themes and techniques involved in applying the SQL language. Forta s examples are clear and his writing style is crisp and concise. As with earlier editions, this revision includes coverage of current versions of all major commercial SQL platforms. New this time around is coverage of MySQL, and PostgreSQL. All examples have been tested against each SQL platform, with incompatibilities or platform distinctives called out and explained.

Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.

解决时钟问题，acm竞赛题 A weird clock marked from 0 to 59 has only a minute hand. It won t move until a special coin is thrown into its box. There are different kinds of coins as your options. However once you make your choice, you cannot use any other kind. There are infinite number of coins of each kind, each marked with a number d ( 0 <= 1000 ), meaning that this coin will make the minute hand move d times clockwise the current time. For example, if the current time is 45, and d = 2. Then the minute hand will move clockwise 90 minutes and will be pointing to 15. Now you are given the initial time s ( 0 <= s <= 59 ) and the coin s type d. Write a program to find the minimum number of d-coins needed to turn the minute hand back to 0.

graspForth is my humble attempt at a Forth-in-C that has the following goals: GCC ......... to support all 32-bit micros that GCC cross-compiles to. Relocatable . to be able to run in-place in either Flash or Ram. Fast ........ to be "not much" slower than an assembly based native Forth. Small ....... to fit-in approx 300 words in less than 25Kbytes on a 32-bit machine. Portable .... to achieve a 5 minute port to a new 32bit micro-processor, or micro-controller.

his folder contains the following files: 1. 02490rxP802-15_SG3a-Channel-Modeling-Subcommittee-Report-Final.doc: This is the final report of the channel modeling sub-committee. 2. cmx_imr.csv (x=1, 2, 3, and 4) represent the files containing the actual 100 channel realizations for CM1, CM2, CM3, and CM4. The columns are organized as (time, amp, time, amp,...) 3. cmx_imr_np.csv (x=1, 2, 3, and 4) represent the files containing the number of paths in each of the 100 multipath realizations. 4. cmx_imr.mat (x=1, 2, 3, and 4) are the .mat files that can be loaded directly into Matlab (TM). 5. *.m files are the Matlab (TM) files used to generate the various channel realizations.
