A further exploration of the problems null brings when it shouldn't be needed. Simple mechanisms for dealing with the problem are presented.

Last month, I needed to use the metaphone and edit (Levenshtein) distance algorithms for a fuzzy search of a MySQL table. Of course, neither is available as a built-in MySQL function. So, I had to install them as UDFs. The MySQL source distribution includes a metaphone UDF function in udf_example.cc. However, I couldn't find a Levenshtein UDF anywhere, so I wrote one, by converting a C implementation by Lorenzo Seidenari. I suspect that other people could benefit from this code, and you can download it from joshdrew.com. I compared the function's output to that of the PHP levensthein() function for a couple million word pairs; the results agreed completely - that's good enough for me. (this code comes with no warranty whatsoever, but I really hope you find it useful)

一個脈寬調變（Pulse-width Modulation, PWM）訊號可控制一顆 DC motor 轉速，或決定一具 servo motor 的方向、位置或轉速。在複雜的機器人身上，常用上好幾顆馬達，因而能以一顆微控制器（microcontroller, uC）產生多組 PWM 訊號是非常實用的。
