问题 How do I change chapter styles in LaTeX report class? I have found something about \makechapterstyle , but it doesn't seem to work on reports (or at least it doesn't work on my report :-) ) I'm prety sure there must be some way to change this. I know that LaTeX is not much of programming, but i dont't know any better place to ask this. 回答1: The package fncychap (pdf) seems to be what you're looking for. With it you should be able to format your chapters quite flexibly without the memoir class

问题 In my experience, package-private visibility for classes in Java is turning out to be redundant. Package-private visibility seems to be based on the premise that a class which is almost-privately used by another class is likely to be kept in the same package. Often this is not the case. Is someone exploring an improved access modifier/alternate mechanism? Problem with trying to use package-private visibility: We are tempted to put functionally unrelated classes in same package to get this

问题 This question already has answers here : Eclipse Shortcut to Split Long Strings (4 answers) Closed 6 years ago . Is there a way to make Eclipse wrap the line with the b's to a length of 120 per line? I wasn't able to configure the code formatter to wrap the line. This really drives me crazy... public class Position { public static void i() { error(

问题 I believe the PEP8 style guide says that both some_kind_of_list = [ 1, 2, 3, 4, 5, 6 ] def function_that_takes_long_arguments( long_argument_1, long_argument_2 ): return long_argument_1 and some_kind_of_list = [ 1, 2, 3, 4, 5, 6 ] def function_that_takes_long_arguments( long_argument_1, long_argument_2 ): return long_argument_1 are acceptable, but does it make sense to use one or the other, e.g., if I move onto C++ later on in my life? EDIT Apologies, for a function, the PEP8 style guide

问题 Is there a way in matlab to assign the output from a function in matlab to a vector within a single line? For example, this function should assign a perimeter and an area value function [p,a] = square_geom(side) p = perimeter_square(side) a = side.^2 [p,a] however when I try to store the data like this v = square_geom(3) It doesn't work. However it is possible to do it like this [p,a] = square_geom(3) v=[p,a] But that just doesn't look as good as keeping it to a single line. Any ideas? 回答1:

问题 Since the advent of AS3 I have been working like this: private var loggy:String; public function getLoggy ():String { return loggy; } public function setLoggy ( loggy:String ):void { // checking to make sure loggy's new value is kosher etc... this.loggy = loggy; } and have avoided working like this: private var _loggy:String; public function get loggy ():String { return _loggy; } public function set loggy ( loggy:String ):void { // checking to make sure loggy's new value is kosher etc...

问题 In the linked SO answer, Eric illustrates a way to call a subroutine, which accepts arrays by reference as arguments, and use the prototypes to allow the caller code to pass the array names without using reference operator \@ ; the way built-ins like push @array, $value do. # Original code: sub Hello { my ($x_ref, $y_ref) = @_; ...} Hello(\@x, \@y); # Same thing using array ref prototype: sub Hello (\@\@$) {...} Hello(@x, @y); My question is, is this considered to be a Best Practice? And what

问题 I'm trying to achieve simple 1px solid red border around each page generated in TCPDF. Previously using other PDF scripts I was forced to draw a rectangle after doing some rough calculations with getting the page width and height and -20px (to allow for 10px indentation on each side). However I'm unsure how I can achieve a similar result with TCPDF. Does anyone have any experience? 回答1: Here you go (this will draw a black line of 15 points around the current page) $pdf = new TCPDF(PDF_PAGE

问题 IMO all code that returns structure directly can be modified to return pointer to structure. When is returning a structure directly a good practice? 回答1: Modified how? Returning a pointer to a static instance of the structure within the function, thus making the function non-reentrant; or by returning a pointer to a heap allocated structure that the caller has to make sure to free and do so appropiately? I would consider returning a structure being the good practice in the general case. 回答2:

问题 Whenever someone starts using the STL and they have a vector, you usually see: vector<int> vec ; //... code ... for( vector<int>::iterator iter = vec.begin() ; iter != vec.end() ; ++iter ) { // do stuff } I just find that whole vector<int>::iterator syntax sickitating. I know you can typedef vector<int>::iterator VecIterInt , and that is slightly better.. But the question is, what's wrong with good ol': for( int i = 0 ; i < vec.size() ; i++ ) { // code } 回答1: When you use index to perform
