MySQL是一个精巧的SQL数据库管理系统,虽然它不是开放源代码的产品,但在某些情况下你可以自由使用。由于它的强大功能、灵活性、丰富的应用编程接口(API)以及精巧的系统结构,受到了广大自由软件爱好者甚至是商业软件用户的青睐,特别是与Apache和PHP/PERL结合,为建立基于数据库的动态网站提供了强大动力。 MySQL有瑞典的T.c.X公司负责开发和维护,MySQL的用户手册很单纯,只有一个集中的<MySQL Reference Manual>,但其内容覆盖了MySQL的所有信息,因此该手册是了解和掌握MySQL的绝佳文献。 虽然对MySQL的开发不能出一份力,但可为它的推广使用尽一份心,面对500多页的参考手册,知道要精确译出它决非易事,但愿几个月的心血能为大家提供一丝微薄的帮助。 由于本人水平有限,文中肯定有不准确的地方,敬请在阅读过程中不吝指出。文中不明之处,请参阅手册原文。 本文的内容针对MySQL 3.23.7alpla,实际上很多内容是通用的。另外,参考手册的几个附录也是很有价值的,但由于时间有限,未能译出,可参见原文。

The Valgrind distribution has multiple tools. The most popular is the memory checking tool (called Memcheck) which can detect many common memory errors such as: * touching memory you shouldn t (eg. overrunning heap block boundaries) * using values before they have been initialized * incorrect freeing of memory, such as double-freeing heap blocks * memory leaks.

工程计算MATLAB code to calculate the reorthogonalized sine tapers input: N = the length of the time series data to be tapered p = the number of tapers requested I = the gap structure a vector of length N I(t) = 1 if there is data at time t, t=1, ..., N I(t) = 0 if there is a gap at time t output: X = N-by-p vector of the reorthogonalized sine taper

zemax源码: This DLL models a standard ZEMAX surface type, either plane, sphere, or conic The surface also demonstrates a user-defined apodization filter The filter is defined as part of the real ray trace, case 5 The filter can be used at the stop to produce x-y Gaussian apodization similar to the Gaussian pupil apodization in ZEMAX but separate in x and y. The amplitude apodization is of the form EXP[-(Gx(x/R)^2 + Gy(y/R)^2)] The transmission is of the form EXP[-2(Gx(x/R)^2 + Gy(y/R)^2)] where x^2 + y^2 = r^2 R = semi-diameter The tranmitted intensity is maximum in the center. T is set to 0 if semi-diameter < 1e-10 to avoid division by zero.

his project was built and tested with WinAVR-20060125. Make sure the MCU target define in the Makefiles corresponds to the AVR you are using!! To build the code, just install WinAVR and run "make" from the console in echomaster and echoslave subdirs. "make program" will program the device if you have a AVRISP attached. Remember to set the AVR device to at least 8MHz. The AVR may use the programmable clock from MC1319x, just remember to check if the MC1319x and SPI communication is working FIRST! Otherwise you wont get any clock signal to the AVR and then you can t program it or reset the fuses! The MC1319x has default clock output of 32kHz so you will have to set your programmer to a very low frequency (<=32kHz/4) to be able to program it while it is running on that!

The Java Cookbook is a comprehensive collection of problems, solutions, and practical examples for anyone programming in Java. Developers will find hundreds of tried-andtrue Java "recipes" covering all of the major APIs as well as some APIs that aren t as well documented in other Java books.

THIS is really two books in one: a tutorial and a reference manual for JDBC, the application programming interface that makes it possible for programmers to access databases from Java. The goal is to be useful to a wide range of readers, from database novices to database experts. Therefore, we have arranged the book so that information needed only by experts is separated out from the basic material. We hope that driver developers as well as application programmers and MIS administrators will find what they need. Because different sections are aimed at different audiences, we expect that few people will read every page. We have sometimes duplicated explanations in an effort to make reading easier for those who do not read all sections. This book will be most helpful to those who have some knowledge of the Java programming language and SQL (Structured Query Language), but one doesn t need to be an expert in either to understand the basic concepts presented here.
