我不知道这是有趣还是悲伤..但是和我一起工作的一个实习生有这个小宝石来计算每个单位的价格

...

// get the units from the form 
int numUnits = Integer.parseInt(request.getParameter("num_pieces")); // this break at random times

//price 
float price = Float.parseFloat(request.getParameter("price")); // same as above

// Under certain conditions the following code blows up. I don't know those conditions.
float pricePerUnit = price / (float)numUnits;

...

$dnstime = time() + 60 * 60 * 24 * 7 * 2; //how long are you staying for vacation on mars? twooo weeeeeks. give dees people air

//我穿上长袍，戴上巫师帽……

// Hack-er-ama

- (void)smartInsertForString:(NSString *)pasteString replacingRange:(NSRange)charRangeToReplace beforeString:(NSString **)beforeString afterString:(NSString **)afterString;
- (NSString *)smartInsertBeforeStringForString:(NSString *)pasteString replacingRange:(NSRange)charRangeToReplace;
- (NSString *)smartInsertAfterStringForString:(NSString *)pasteString replacingRange:(NSRange)charRangeToReplace;

/* Java note: The second and third methods are the primitives and are the 
methods exposed in Java.  The first method calls the other two.  All 
Objective-C code calls the first method.  In either Objective-C or Java any 
overriding should be done for the second and third methods, not the first 
method.  This will all work out correctly with the exception of existing code 
that overrides the first method.  Existing subclasses that do this will not 
have their implementations available to Java developers. Isn't Java wonderful? */
