  • Are nullable types preferable to magic numbers?

    - by Matt H
    I have been having a little bit of a debate with a coworker lately. We are specifically using C#, but this could apply to any language with nullable types. Say for example you have a value that represents a maximum. However, this maximum value is optional. I argue that a nullable number would be preferable. My coworker favors the use of zero, citing precedent. Granted, things like network sockets have often used zero to represent an unlimited timeout. If I were to write code dealing with sockets today, I would personally use a nullable value, since I feel it would better represent the fact that there is NO timeout. Which representation is better? Both require a condition checking for the value meaning "none", but I believe that a nullable type conveys the intent a little bit better.

  • Image Magic Make Fails - PHP extension

    - by Kyle Adams
    So I was doing the following: sudo apt-get install php-pear php5-dev sudo apt-get install imagemagick libmagickwand-dev sudo pecl install imagick It all works till I get the error: make: *** [imagick_class.lo] Error 1 ERROR: `make' failed Which according to blog posts and forms is because of libmagick9-dev, how ever when trying to install this I get: sudo apt-get install libmagick9-dev Reading package lists... Done Building dependency tree Reading state information... Done Package libmagick9-dev is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source However the following packages replace it: graphicsmagick-libmagick-dev-compat E: Package 'libmagick9-dev' has no installation candidate Thoughts?

  • Excel INDIRECT function and conditional formatting - highlighting a row

    - by Ehryk
    I'm having an issue with conditional formatting using the INDIRECT function. I'm doing something similar to Using INDIRECT and AND/IF for conditional formatting , but the only answer there isn't working for me. Basically, I want to highlight rows where B is not blank and F is blank. INDIRECT will work for ONE of the conditions, but = AND(INDIRECT("B"&ROW()) > 0, INDIRECT("F"&ROW()) = "") does not work at all. The answer in the question points to replacing the references with relative ones, so I'm thinking this should work: = AND ($B2 > 0, $F2 = "") But it does not, nor does ISBLANK($F@) or ISEMPTY($F2) (the cell contains a formula that sometimes will return "", I want the row highlighted in these cases but only when something is in column B). Am I missing something about relative references? Why doesn't INDIRECT work with AND/OR?

  • The Magic of Keywords

    When you ask this question of the search engines, there are many definitions all meaning the same thing. The one I liked the best is "Keywords are the words or phrases used in a Web Page that will be noticed and indexed by Search Engines, and guide people to your web site when they type in those words or phrases at the Search Engine." In fact keywords are a very necessary part of an internet marketer's resources, if you want people to find and read what you have written or advertised.

  • Function key taken by another program, how to default it

    - by Milox
    Everytime I press the F11 key it opens up a browser window with the same URL. This happens anywhere I press it and I need this key to have it's default behavior because I use it to program on Visual Studio (Windows 7). Any ideas why this is happening and how to go back to default function keys?, I haven't installed anything that I remember can cause this behavior. This is a standard Dell desktop key board, no multimedia keys, like this one: Firing URL is http://argos:8080/Login.jsp?jsessionid=55rh3obsahm9m seems like one of our company's internal addresses but IT guys say they have no idea about it. I don't see any suspicious software that can be causing this.

  • Bash/shell script - shell output redirection inside a function

    - by Josh
    function grabSourceFile { cd /tmp/lmpsource wget $1 > $LOG baseName=$(basename $1) tar -xvf $baseName > $LOG cd $baseName } When I call this function The captured output is not going to the log file. The output redirection works fine until I call the function. The $LOG variable is set at the top of the file. I tried echoing statements and they would not print. I am guessing the function captures the output itself? If so how do push the output to the file instead of the console. (The wget above prints to console, while an echo inside the function does nothing.)

  • SqlServer2008 - Can I Alter a Scalar Function while it is referenced in many places

    - by Casey C.
    We have a scalar function that returns a DateTime. It performs a couple of quick table selects to get its return value. This function is already in use throughout the database - in default constraints, stored procs, etc. I would like to change the implementation of the function (to remove the table hits and make it more efficient) but apparently I can't do that while it is referenced by other objects in the database. Will I actually need to update every object in the database that references it to remove the reference, update the function and then update all those objects to restore the reference to the function? Thanks for any insight you can give.

  • Vim: Call an ex command (set) from function?

    - by sixtyfootersdude
    Drawing a blank on this, and google was not helpful. Want to make a function like this: function JakPaste() let tmp = :set paste? if tmp == "paste" set nopaste else set paste endif endfunction map <F2> :call JakPaste()<CR> However this does not work. I have isolated the broken line: function JakPaste() let tmp = set paste? endfunction map <F2> :call JakPaste()<CR> Pressing F2 results in this error: Error detected while processing function JakPaste: line 1: E121: Undefined variable: set E15: Invalid expression: set paste? Hit ENTER or type command to continue How should I call an ex command (set) from a vim function? This seems somewhat relevant however I still don't get it.

  • How flexible is the 'indirect' function?

    - by Chuck
    My curiosity pushes me to ask this question. If I were to have a series of functions that referenced a different column in a worksheet but all ended on the same row of data is there a way to point the 'row' part of a cell reference to a blank cell and use it has a variable to show the results of the functions up to a desired row simultaneously? Example: =Average('worksheet 1'.$A$1:'worksheet 1'.$A100) =Max('worksheet 1'.$B$1:'worksheet 1'.$B100) =Min('worksheet 1'.$C$1:'worksheet 1'.$C100) =Sum('worksheet 1'.$D$1:'worksheet 1'.$D100) Pseudo formulas... =Average('worksheet 1'.$A$1:'worksheet 1'.$A*('worksheet 2'.$A$1)*) =Max('worksheet 1'.$B$1:'worksheet 1'.$B*('worksheet 2'.$A$1)*) =Min('worksheet 1'.$C$1:'worksheet 1'.$C*('worksheet 2'.$A$1)*) =Sum('worksheet 1'.$D$1:'worksheet 1'.$D*('worksheet 2'.$A$1)*) Where 'worksheet 2'.$A$1 would only contain a number corresponding to a row in 'worksheet 1'. After stumbling upon and playing with the indirect() function I have only been able to replace the entire cell reference (Column and Row) with any success. The formula so far =SUM('worksheet 1'.C3:INDIRECT(A1)) Where A1 is on 'worksheet 2' and contains a full cell reference pointing to 'worksheet 1'. Any pointers?

  • How to create a function with vectors and vertical asymptote using MATLAB

    - by Pedro J Trinidad
    Plot the function f(x) = 1.5x / x-4 for -10 equal or less than X equal or less than 10. Notice that the function have a vertical asymptote at x = 4. Plot the function by creating two vectors for the domain of x. The first vector (call it x1) with elements from -10 to 3.7, and the second vector (calle it x2) with elements from 4.3 to 10. For each of the X vector create a Y vector (call them y1 and y2) with the corresponding values of Y according to the function. To plot the function make two curves in the same plot (y1 vs. x1 and y2 vs. x2).

  • Lua : Dynamicly calling a function with arguments.

    - by Tipx
    Using Lua, I'm trying to dynamicly call a function with parameters. What I want to have it done is I send a string to be parsed in a way that : 1st argument is a class instance "Handle" 2nd is the function to be called All that is left are arguments "modules" is a a table like { string= } split() is a simple parser that returns a table with indexed strings function Dynamic(msg) local args = split(msg, " ") module = args[1] table.remove(args, 1) if module then module = modules[module] command = args[1] table.remove(args, 1) if command then if not args then module[command]() else module[command](unpack(args)) -- Reference 1 end else -- Function doesnt exist end else -- Module doesnt exist end end When I try this with "ignore remove bob", by "Reference 1", it tries to call "remove" on the instance associated with "ignore" in modules, and gives the argument "bob", contained in a table (with a single value). However, on the other side of the call, the remove function does not receive the argument. I even tried to replace the "Reference 1" line with module[command]("bob") but I get the same result.

  • [C++]Advantage of using a static member function instead of an equivalent non-static member function

    - by jonathanasdf
    I was wondering whether there's any advantages to using a static member function when there is a non-static equivalent. Will it result in faster execution (because of not having to care about all of the member variables), or maybe less use of memory (because of not being included in all instances)? Basically, the function I'm looking at is an utility function to rotate an integer array representing pixel colours an arbitrary number of degrees around an arbitrary centre point. It is placed in my abstract Bullet base class, since only the bullets will be using it and I didn't want the overhead of calling it in some utility class. It's a bit too long and used in every single derived bullet class, making it probably not a good idea to inline. How would you suggest I define this function? As a static member function of Bullet, of a non-static member function of Bullet, or maybe not as a member of Bullet but defined outside of the class in Bullet.h? What are the advantages and disadvantages of each?

  • How to run Jquery constructor from own function?

    - by Invidian
    I need to create a function which will returning jQuery.Color object and i have no idea how to do it. Here is code example function newcolor () { var obj = new $.Color( 'rgb(0,0,0)' ); return obj;} var foo = newcolor(); foo.red(); Edit: My full code: function my (element,a,b,c){ //class my this.target = $(elem); this.new_color = function (a,b,c) { return new $.Color( 'rgb('+a+','+b+','+c+')'); } this.base_color = new_color (a,b,c); this.colorize = function () ( this.target.css({ background-color: new_color }); } var div = new My($('foo'),0,0,0); div.new_color(255,255,255); div.colorize(); My goal is to create class which can hold jquery element and operate on it. Now I'm stuck on returning $.Color().
