• C++ 2d Array Class Function Call Help

  - by johnny-conrad

  I hope this question takes a simple fix, and I am just missing something very small. I am in my second semester of C++ in college, and we are just getting into OOP. This is my first OOP program, and it is causing me a little problem. Here are the errors I am getting: Member function must be called or its address taken in function displayGrid(int,Cell ( *)[20]) Member function must be called or its address taken in function Turn(int,int,Cell ( *)[20]) Member function must be called or its address taken in function Turn(int,int,Cell ( *)[20]) Warning: Parameter 'grid' is never used in function displayGrid(int,Cell ( *)[20]) Here is all of my code. I am aware It is much more code than necessary, sorry if it makes it more difficult. I was worried that I might accidentally delete something. const int MAX=20; //Struct Cell holds player and their symbol. class Cell { private: int Player; char Symbol; public: Cell(void); void setPlayer(int); void setSymbol(char); int getPlayer(void); char getSymbol(void); }; Cell::Cell(void) { Symbol ='-'; } void Cell::setPlayer(int player_num) { Player = player_num; } void Cell::setSymbol(char rps) { Symbol = rps; } int Cell::getPlayer(void) { return Player; } char Cell::getSymbol(void) { return Symbol; } void Turn(int, int, Cell[MAX][MAX]); void displayGrid(int, Cell[MAX][MAX]); void main(void) { int size; cout << "How big would you like the grid to be: "; cin >> size; //Checks to see valid grid size while(size>MAX || size<3) { cout << "Grid size must between 20 and 3." << endl; cout << "Please re-enter the grid size: "; cin >> size; } int cnt=1; int full; Cell grid[MAX][MAX]; //I use full to detect when the game is over by squaring size. full = size*size; cout << "Starting a new game." << endl; //Exits loop when cnt reaches full. while(cnt<full+1) { displayGrid(size, grid); //calls function to display grid if(cnt%2==0) //if cnt is even then it's 2nd players turn cout << "Player 2's turn." << endl; else cout << "Player 1's turn" << endl; Turn(size, cnt, grid); //calls Turn do each players turn cnt++; } cout << endl; cout << "Board is full... Game Over" << endl; } void displayGrid(int size, Cell grid[MAX][MAX]) { cout << endl; cout << " "; for(int x=1; x<size+1; x++) // prints first row cout << setw(3) << x; // of numbers. cout << endl; //Nested-For prints the grid. for(int i=1; i<size+1; i++) { cout << setw(2) << i; for(int c=1; c<size+1; c++) { cout << setw(3) << grid[i][c].getSymbol; } cout << endl; } cout << endl; } void Turn(int size, int cnt, Cell grid[MAX][MAX]) { char temp; char choice; int row=0; int column=0; cout << "Enter the Row: "; cin >> row; cout << "Enter the Column: "; cin >> column; //puts what is in the current cell in "temp" temp = grid[row][column].getSymbol; //Checks to see if temp is occupied or not while(temp!='-') { cout << "Cell space is Occupied..." << endl; cout << "Enter the Row: "; cin >> row; cout << "Enter the Column: "; cin >> column; temp = grid[row][column].getSymbol; //exits loop when finally correct } if(cnt%2==0) //if cnt is even then its player 2's turn { cout << "Enter your Symbol R, P, or S (Capitals): "; cin >> choice; grid[row][column].setPlayer(1); in >> choice; } //officially sets choice to grid cell grid[row][column].setSymbol(choice); } else //if cnt is odd then its player 1's turn { cout << "Enter your Symbol r, p, or s (Lower-Case): "; cin >> choice; grid[row][column].setPlayer(2); //checks for valid input by user1 while(choice!= 'r' && choice!='p' && choice!='s') { cout << "Invalid Symbol... Please Re-Enter: "; cin >> choice; } //officially sets choice to grid cell. grid[row][column].setSymbol(choice); } cout << endl; } Thanks alot for your help!

• How can I fix my program from crashing in C++?

  - by Rachel

  I'm very new to programming and I am trying to write a program that adds and subtracts polynomials. My program sometimes works, but most of the time, it randomly crashes and I have no idea why. It's very buggy and has other problems I'm trying to fix, but I am unable to really get any further coding done since it crashes. I'm completely new here but any help would be greatly appreciated. Here's the code: #include <iostream> #include <cstdlib> using namespace std; int getChoice(void); class Polynomial10 { private: double* coef; int degreePoly; public: Polynomial10(int max); //Constructor for a new Polynomial10 int getDegree(){return degreePoly;}; void print(); //Print the polynomial in standard form void read(); //Read a polynomial from the user void add(const Polynomial10& pol); //Add a polynomial void multc(double factor); //Multiply the poly by scalar void subtract(const Polynomial10& pol); //Subtract polynom }; void Polynomial10::read() { cout << "Enter degree of a polynom between 1 and 10 : "; cin >> degreePoly; cout << "Enter space separated coefficients starting from highest degree" << endl; for (int i = 0; i <= degreePoly; i++) { cin >> coef[i]; } } void Polynomial10::print() { for(int i=0;i<=degreePoly;i++) { if(coef[i] == 0) { cout << ""; } else if(i>=0) { if(coef[i] > 0 && i!=0) { cout<<"+"; } if((coef[i] != 1 && coef[i] != -1) || i == degreePoly) { cout << coef[i]; } if((coef[i] != 1 && coef[i] != -1) && i!=degreePoly ) { cout << "*"; } if (i != degreePoly && coef[i] == -1) { cout << "-"; } if(i != degreePoly) { cout << "x"; } if ((degreePoly - i) != 1 && i != degreePoly) { cout << "^"; cout << degreePoly-i; } } } } void Polynomial10::add(const Polynomial10& pol) { for(int i = 0; i<degreePoly; i++) { int degree = degreePoly; coef[degreePoly-i] += pol.coef[degreePoly-(i+1)]; } } void Polynomial10::subtract(const Polynomial10& pol) { for(int i = 0; i<degreePoly; i++) { coef[degreePoly-i] -= pol.coef[degreePoly-(i+1)]; } } void Polynomial10::multc(double factor) { //int degreePoly=0; //double coef[degreePoly]; cout << "Enter the scalar multiplier : "; cin >> factor; for(int i = 0; i<degreePoly; i++) { coef[i] *= factor; } }; Polynomial10::Polynomial10(int max) { degreePoly=max; coef = new double[degreePoly]; for(int i; i<degreePoly; i++) { coef[i] = 0; } } int main() { int choice; Polynomial10 p1(1),p2(1); cout << endl << "CGS 2421: The Polynomial10 Class" << endl << endl << endl; cout << "0. Quit\n" << "1. Enter polynomial\n" << "2. Print polynomial\n" << "3. Add another polynomial\n" << "4. Subtract another polynomial\n" << "5.

• Trouble passing a template function as an argument to another function in C++

  - by Darel

  Source of the problem -Accelerated C++, problem 8-5 I've written a small program that examines lines of string input, and tallies the number of times a word appears on a given line. The following code accomplishes this: #include <map> #include <iostream> #include <string> #include <vector> #include <list> #include <cctype> #include <iterator> using std::vector; using std::string; using std::cin; using std::cout; using std::endl; using std::getline; using std::istream; using std::string; using std::list; using std::map; using std::isspace; using std::ostream_iterator; using std::allocator; inline void keep_window_open() { cin.clear(); cout << "Please enter EOF to exit\n"; char ch; cin >> ch; return; } template <class Out> void split(const string& s, Out os) { vector<string> ret; typedef string::size_type string_size; string_size i = 0; // invariant: we have processed characters `['original value of `i', `i)' while (i != s.size()) { // ignore leading blanks // invariant: characters in range `['original `i', current `i)' are all spaces while (i != s.size() && isspace(s[i])) ++i; // find end of next word string_size j = i; // invariant: none of the characters in range `['original `j', current `j)' is a space while (j != s.size() && !isspace(s[j])) ++j; // if we found some nonwhitespace characters if (i != j) { // copy from `s' starting at `i' and taking `j' `\-' `i' chars *os++ = (s.substr(i, j - i)); i = j; } } } // find all the lines that refer to each word in the input map<string, vector<int> > xref(istream& in) // works // now try to pass the template function as an argument to function - what do i put for templated type? //map<string, vector<int> > xref(istream& in, void find_words(vector<string, typedef Out) = split) #LINE 1# { string line; int line_number = 0; map<string, vector<int> > ret; // read the next line while (getline(in, line)) { ++line_number; // break the input line into words vector<string> words; // works // #LINE 2# split(line, back_inserter(words)); // #LINE 3# //find_words(line, back_inserter(words)); // #LINE 4# attempting to use find_words as an argument to function // remember that each word occurs on the current line for (vector<string>::const_iterator it = words.begin(); it != words.end(); ++it) ret[*it].push_back(line_number); } return ret; } int main() { cout << endl << "Enter lines of text, followed by EOF (^Z):" << endl; // call `xref' using `split' by default map<string, vector<int> > ret = xref(cin); // write the results for (map<string, vector<int> >::const_iterator it = ret.begin(); it != ret.end(); ++it) { // write the word cout << it->first << " occurs on line(s): "; // followed by one or more line numbers vector<int>::const_iterator line_it = it->second.begin(); cout << *line_it; // write the first line number ++line_it; // write the rest of the line numbers, if any while (line_it != it->second.end()) { cout << ", " << *line_it; ++line_it; } // write a new line to separate each word from the next cout << endl; } keep_window_open(); return 0; } As you can see, the split function is a template function to handle various types of output iterators as desired. My problem comes when I try to generalize the xref function by passing in the templated split function as an argument. I can't seem to get the type correct. So my question is, can you pass a template function to another function as an argument, and if so, do you have to declare all types before passing it? Or can the compiler infer the types from the way the templated function is used in the body? To demonstrate the errors I get, comment out the existing xref function header, and uncomment the alternate header I'm trying to get working (just below the following commment line.) Also comment the lines tagged LINE 2 and LINE 3 and uncomment LINE 4, which is attempting to use the argument find_words (which defaults to split.) Thanks for any feedback!

• PHP 'Years' array

  - by J M 4

  I am trying to create an array for years which i will use in the DOB year piece of a form I am building. Currently, I know there are two ways to handle the issue but I don't really care for either: 1) Range: I know I can create a year array using the following <?php $year = range(1910,date("Y")); $_SESSION['years_arr'] = $year; ?> the problem with Point 1 is two fold: a) my function call shows the first year as 'selected' instead of "Year" as I have as option="0", and b) I want the years reversed so 2010 is the first in the least and shown decreasing. My function call is: PHP <?php function showOptionsDrop($array, $active, $echo=true){ $string = ''; foreach($array as $k => $v){ $s = ($active == $k)? ' selected="selected"' : ''; $string .= '<option value="'.$k.'"'.$s.'>'.$v.'</option>'."\n"; } if($echo) echo $string; else return $string; } ?> HTML <table> <tr> <td>State:</td> <td><select name="F1State"><option value="0">Choose a year</option><?php showOptionsDrop($_SESSION['years_arr'], null, true); ?></select> </td> </tr> </table> 2) Long Array I know i can physically create an array with years listed out but this takes up a lot of space and time if I ever want to go back and modify. ex: PHP $years = array('1900'=>"1900", '1901'=>"1901", '1902'=>"1902", '1903'=>"1903", '1904'=>"1904", '1905'=>"1905", '1906'=>"1906", '1907'=>"1907", '1908'=>"1908", '1909'=>"1909", '1910'=>"1910", '1911'=>"1911", '1912'=>"1912", '1913'=>"1913", '1914'=>"1914", '1915'=>"1915", '1916'=>"1916", '1917'=>"1917", '1918'=>"1918", '1919'=>"1919", '1920'=>"1920", '1921'=>"1921", '1922'=>"1922", '1923'=>"1923", '1924'=>"1924", '1925'=>"1925", '1926'=>"1926", '1927'=>"1927", '1928'=>"1928", '1929'=>"1929", '1930'=>"1930", '1931'=>"1931", '1932'=>"1932", '1933'=>"1933", '1934'=>"1934", '1935'=>"1935", '1936'=>"1936", '1937'=>"1937", '1938'=>"1938", '1939'=>"1939", '1940'=>"1940", '1941'=>"1941", '1942'=>"1942", '1943'=>"1943", '1944'=>"1944", '1945'=>"1945", '1946'=>"1946", '1947'=>"1947", '1948'=>"1948", '1949'=>"1949", '1950'=>"1950", '1951'=>"1951", '1952'=>"1952", '1953'=>"1953", '1954'=>"1954", '1955'=>"1955", '1956'=>"1956", '1957'=>"1957", '1958'=>"1958", '1959'=>"1959", '1960'=>"1960", '1961'=>"1961", '1962'=>"1962", '1963'=>"1963", '1964'=>"1964", '1965'=>"1965", '1966'=>"1966", '1967'=>"1967", '1968'=>"1968", '1969'=>"1969", '1970'=>"1970", '1971'=>"1971", '1972'=>"1972", '1973'=>"1973", '1974'=>"1974", '1975'=>"1975", '1976'=>"1976", '1977'=>"1977", '1978'=>"1978", '1979'=>"1979", '1980'=>"1980", '1981'=>"1981", '1982'=>"1982", '1983'=>"1983", '1984'=>"1984", '1985'=>"1985", '1986'=>"1986", '1987'=>"1987", '1988'=>"1988", '1989'=>"1989", '1990'=>"1990", '1991'=>"1991", '1992'=>"1992", '1993'=>"1993", '1994'=>"1994", '1995'=>"1995", '1996'=>"1996", '1997'=>"1997", '1998'=>"1998", '1999'=>"1999", '2000'=>"2000", '2001'=>"2001", '2002'=>"2002", '2003'=>"2003", '2004'=>"2004", '2005'=>"2005", '2006'=>"2006", '2007'=>"2007", '2008'=>"2008", '2009'=>"2009", '2010'=>"2010"); $_SESSION['years_arr'] = $years_arr; Does anybody have a recommended idea how to work - or just how to simply modify my existing code?

• Passing ActionListeners in Java, pack()

  - by Crystal

  Two questions. First question is I'm trying to create a simple form that when you press a button, it adds a Person object to the ArrayList. However, since I am not used to GUIs, I tried creating one and am first just trying to get the user input from the JTextField, create an ActionListener object of the appropriate type, so once that works, then I can pass in all the JTextField inputs to create my Person object. Unfortunately, I am not getting any data when I type in something to the firstName JTextField and was wondering if someone could look at my code below. import java.awt.*; import java.awt.event.*; import javax.swing.*;

System.out.println("Test" + text); } public void actionPerformed(ActionEvent e) { System.out.println("Hello" + name); } public void setName(String name) { this.name = name; } private String name; } } Second question is, how do I make my form not take up the whole center space. I don't like the stretch look and was hoping the JTextFields could be just one line long, not a big box. Same thing with the buttons. Any thoughts? Thanks.

• css menu for cross browser...mobile and desktop

  - by user1763319

  I made a cross browser drop down menu, which works well with IE6. However, I have problems with other browsers such as IE9, Firefox, Chrome... etc. How can I modify my HTML and CSS to get the same effect that works in IE6? Link to JSFiddle Here is my CSS: <style> .bar ul,li{ z-index:999; margin:0; padding:0; } .bar { color: #FFFFFF; font-weight: bold; text-align: center; } .bar a { padding: 11px; } .bar a:visited { color: #FFFFFF; font-weight: bold; text-decoration:none } .bar a:link { color: #FFFFFF; font-weight: bold; text-decoration:none } .bar a:hover { color: #FFFFFF; font-weight: bold; text-decoration:underline } #nav0{ list-style:none; font-weight:bold; /* Clear floats */ float:left; width:100%; } #nav0 li{ float:left; margin-right:10px; position:relative; } #nav0 a{ display:block; padding:5px; color:#fff; background:#003399; text-decoration:none; } #nav0 a:hover{ color:#fff; background:#333; text-decoration:underline; } /*--- DROPDOWN ---*/ #nav0 ul{ background:#fff; background:rgba(255,255,255,0); list-style:none; position:absolute; left:-9999px; } #nav0 ul li{ padding-top:1px; float:none; } #nav0 ul a{ white-space:nowrap; } #nav0 li:hover ul{ left:0; } #nav0 li:hover a{ text-decoration:underline; } #nav0 li:hover ul a{ text-decoration:none; } #nav0 li:hover ul li a:hover{ background:#333; } #nav0 li ul li a{ text-align: left; } #nav0 li:hover ul li ul { display:block; background:#003399; float:left; position:relative; padding-left:20px; } #nav0 li ul li:hover ul { display:block; background:#003399; float:left; position:relative; padding-left:20px; } </style> Here is my HTML: <body bgcolor="#79A6A6"> <div id="page" align="center"> <table class="bar" border="0" width="960" cellspacing="0" cellpadding="0" id="table_bar" bgcolor="#003399"> <tr> <td> <ul id="nav0"> <li><a><strong>Home</strong> </a> <ul> <li><a href="#" title>Top Item 1</a><ul> <li><a href="#" title="-">Item 1</a></li> <li><a href="#" title="-">Item 2</a></li> </ul> </li> <li><a href="#" title>Top Item 2</a><ul> <li><a href="@" title>Item 3</a></li> <li><a href="@" title>Item 4</a></li> </ul> </li> </ul> </li> <li><a><strong>Home</strong> </a> <ul> <li><a href="#" title>Top Title</a><ul> <li><a href="#" title="-">title</a></li> <li><a href="#" title="-">title123456789</a></li> </ul> </li> <li><a href="#" title>Top Hello</a><ul> <li><a href="@" title>hello</a></li> <li><a href="@" title>hello123456789</a></li> </ul> </li> </ul> </li> </ul> </li> <ul> </ul> </td> <td width="50" style="text-align: left">&nbsp;</td> </tr> </table> </div> </body> In ie6 Home Top Item 1 Item 1 Item 2 Top Item 2 Item3 Item4 In ie9 Home Top Item 1 Top Item 2 Item 2 Item 3 Item 4

  - by Subhransu

  I have website working fine before. But now its not able to connect to the server(I believe that is the problem). But its strange that the message not able to connect to the server is not coming and its keep connecting... for infinite time. Here is the screenshot. Here are some of the useful details about the status of the server. Application starts when server wakes up are: cd /etc/init.d/ Application server running in my server : Traceroute: UPDATE: ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 19204 744 ?

• Sendmail Failing to Forward Locally Addressed Mail to Exchange Server

  - by DomainSoil

  I've recently gained employment as a web developer with a small company. What they neglected to tell me upon hire was that I would be administrating the server along with my other daily duties. Now, truth be told, I'm not clueless when it comes to these things, but this is my first rodeo working with a rack server/console.. However, I'm confident that I will be able to work through any solutions you provide. Short Description: When a customer places an order via our (Magento CE 1.8.1.0) website, a copy of said order is supposed to be BCC'd to our sales manager. I say supposed because this was a working feature before the old administrator left. Long Description: Shortly after I started, we had a server crash which required a server restart. After restart, we noticed a few features on our site weren't working, but all those have been cleaned up except this one. I had to create an account on our server for root access. When a customer places an order, our sites software (Magento CE 1.8.1.0) is configured to BCC the customers order email to our sales manager. We use a Microsoft Exchange 2007 Server for our mail, which is hosted on a different machine (in-house) that I don't have access to ATM, but I'm sure I could if needed. As far as I can tell, all other external emails work.. Only INTERNAL email addresses fail to deliver. I know this because I've also tested my own internal address via our website. I set up an account with an internal email, made a test order, and never received the email. I changed my email for the account to an external GMail account, and received emails as expected. Let's dive into the logs and config's. For privacy/security reasons, names have been changed to the following: domain.com = Our Top Level Domain. email.local = Our Exchange Server. example.com = ANY other TLD. OLDadmin = Our previous Server Administrator. NEWadmin = Me. SALES@ = Our Sales Manager. Customer# = A Customer. Here's a list of the programs and config files used that hold relevant for this issue: Server: > [root@www ~]# cat /etc/centos-release CentOS release 6.3 (final) Sendmail: > [root@www ~]# sendmail -d0.1 -bt < /dev/null Version 8.14.4 ========SYSTEM IDENTITY (after readcf)======== (short domain name) $w = domain (canonical domain name) $j = domain.com (subdomain name) $m = com (node name) $k = www.domain.com > [root@www ~]# rpm -qa | grep -i sendmail sendmail-cf-8.14.4-8.e16.noarch sendmail-8.14-4-8.e16.x86_64 nslookup: > [root@www ~]# nslookup email.local Name: email.local Address: 192.168.1.50 hostname: > [root@www ~]# hostname www.domain.com /etc/mail/access: > [root@www ~]# vi /etc/mail/access Connect:localhost.localdomain RELAY Connect:localhost RELAY Connect:127.0.0.1 RELAY /etc/mail/domaintable: > [root@www ~]# vi /etc/mail/domaintable # /etc/mail/local-host-names: > [root@www ~]# vi /etc/mail/local-host-names # /etc/mail/mailertable: > [root@www ~]# vi /etc/mail/mailertable # /etc/mail/sendmail.cf: > [root@www ~]# vi /etc/mail/sendmail.cf ###################################################################### ##### ##### DO NOT EDIT THIS FILE!

• LSI 9285-8e and Supermicro SC837E26-RJBOD1 duplicate enclosure ID and slot numbers

  - by Andy Shinn

  I am working with 2 x Supermicro SC837E26-RJBOD1 chassis connected to a single LSI 9285-8e card in a Supermicro 1U host. There are 28 drives in each chassis for a total of 56 drives in 28 RAID1 mirrors. The problem I am running in to is that there are duplicate slots for the 2 chassis (the slots list twice and only go from 0 to 27). All the drives also show the same enclosure ID (ID 36). However, MegaCLI -encinfo lists the 2 enclosures correctly (ID 36 and ID 65). My question is, why would this happen? Is there an option I am missing to use 2 enclosures effectively? This is blocking me rebuilding a drive that failed in slot 11 since I can only specify enclosure and slot as parameters to replace a drive. When I do this, it picks the wrong slot 11 (device ID 46 instead of device ID 19). Adapter #1 is the LSI 9285-8e, adapter #0 (which I removed due to space limitations) is the onboard LSI.

After getting in contact with a very knowledgeable Supermicro tech, they provided us with a tool called Xflash (doesn't appear to be readily available on their FTP). When we gathered some information using this utility, my colleague found something very strange: root@mogile2 test]# ./xflash.dat -i get avail Initializing Interface. Expander: SAS2X36 (SAS2x36) 1) SAS2X36 (SAS2x36) (50030480:00EE917F) (0.0.0.0) 2) SAS2X36 (SAS2x36) (50030480:00E9D67F) (0.0.0.0) 3) SAS2X36 (SAS2x36) (50030480:0112D97F) (0.0.0.0) This lists the connected enclosures. You see the 3 connected (we have since added a 3rd and a 4th which is not yet showing up) with their respective SAS address / WWN (50030480:00EE917F). Now we can use this address to get information on the individual enclosures: [root@mogile2 test]# ./xflash.dat -i 5003048000EE917F get exp Initializing Interface. Expander: SAS2X36 (SAS2x36) Reading the expander information.......... Expander: SAS2X36 (SAS2x36) B3 SAS Address: 50030480:00EE917F Enclosure Logical Id: 50030480:0000007F IP Address: 0.0.0.0 Component Identifier: 0x0223 Component Revision: 0x05 [root@mogile2 test]# ./xflash.dat -i 5003048000E9D67F get exp Initializing Interface.

Expander: SAS2X36 (SAS2x36) Reading the expander information.......... Expander: SAS2X36 (SAS2x36) B3 SAS Address: 50030480:0112D97F Enclosure Logical Id: 50030480:0112D97F IP Address: 0.0.0.0 Component Identifier: 0x0223 Component Revision: 0x05 Did you catch it? The first 2 enclosures logical ID is partially masked out where the 3rd one (which has a correct unique enclosure ID) is not. We pointed this out to Supermicro and were able to confirm that this address is supposed to be set during manufacturing and there was a problem with a certain batch of these enclosures where the logical ID was not set. We believe that the RAID controller is determining the ID based on the logical ID and since our first 2 enclosures have the same logical ID, they get the same enclosure ID. We also confirmed that 0000007F is the default which comes from LSI as an ID. The next pointer that helps confirm this could be a manufacturing problem with a run of JBODs is the fact that all 6 of the enclosures that have this problem begin with 00E. I believe that between 00E8 and 00EE Supermicro forgot to program the logical IDs correctly and neglected to recall or fix the problem post production. Fortunately for us, there is a tool to manage the WWN and logical ID of the devices from Supermicro: ftp://ftp.supermicro.com/utility/ExpanderXtools_Lite/. Our next step is to schedule a shutdown of these JBODs (after data migration) and reprogram the logical ID and see if it solves the problem. Update 06/28/12 #2: I just discovered this FAQ at Supermicro while Google searching for "lsi 0000007f": http://www.supermicro.com/support/faqs/faq.cfm?faq=11805. I still don't understand why, in the last several times we contacted Supermicro, they would have never directed us to this article :\

• Lot's of errors by insserv on apt-get operations after trying to install tomcat

  - by yankee

  I wanted to install tomcat on my Debian 6.0.4 machine. I tried apt-get install tomcat6-user which worked fine. But then I changed my mind about the user installation and wanted to install the package tomcat6. This resulted in a bunch of errors (see below). Now whatever I try to do with apt-get or with aptitude (trying to remove tomcat6-user, trying to remove tomcat6, trying to perform an apt-get upgrade,...) just results in the same list of errors. How did I manage that? And how can I fix it? # apt-get install tomcat6 Reading package lists... Done Building dependency tree Reading state information...

• Kernel oops on Linux running in VirtualBox breaks some IO-related functionality on the server

  - by Kristoffer E

  We are having problems with CentOS release 6.3 running in VirtualBox on Windows 7 machines. The symptoms are the following: Everything works as normal for several hours, even days. Then something happens which breaks the system. What we still can do after this something happens: Access the web server Use existing SSH sessions to run top and free What does not work: Starting new SSH sessions (hangs after username and password is entered) Running ls in existing SSH sessions (hangs) SSI includes from our web servers that fetch data from remote machines probably more What we see on the server when this something happens is the following: Load average go from basically nothing to around 3 CPU usage is still low (5%) Disk activity is low (running iostat) Plenty of memory available Plenty of disk space available In /var/log/messages we get the following: Jun 14 01:10:48 devvm kernel: e1000 0000:00:03.0: eth0: Detected Tx Unit Hang Jun 14 01:10:48 devvm kernel: Tx Queue <0> Jun 14 01:10:48 devvm kernel: TDH <2e> Jun 14 01:10:48 devvm kernel: TDT <30> Jun 14 01:10:48 devvm kernel: next_to_use <30> Jun 14 01:10:48 devvm kernel: next_to_clean <2e> Jun 14 01:10:48 devvm kernel: buffer_info[next_to_clean] Jun 14 01:10:48 devvm kernel: time_stamp <1038284db> Jun 14 01:10:48 devvm kernel: next_to_watch <2f> Jun 14 01:10:48 devvm kernel: jiffies <103828b42> Jun 14 01:10:48 devvm kernel: next_to_watch.status <0> Jun 14 01:10:50 devvm kernel: e1000 0000:00:03.0: eth0: Detected Tx Unit Hang Jun 14 01:10:50 devvm kernel: Tx Queue <0> Jun 14 01:10:50 devvm kernel: TDH <2e> Jun 14 01:10:50 devvm kernel: TDT <30> Jun 14 01:10:50 devvm kernel: next_to_use <30> Jun 14 01:10:50 devvm kernel: next_to_clean <2e> Jun 14 01:10:50 devvm kernel: buffer_info[next_to_clean] Jun 14 01:10:50 devvm kernel: time_stamp <1038284db> Jun 14 01:10:50 devvm kernel: next_to_watch <2f> Jun 14 01:10:50 devvm kernel: jiffies <103829312> Jun 14 01:10:50 devvm kernel: next_to_watch.status <0> Jun 14 01:10:52 devvm kernel: ------------[ cut here ]------------ Jun 14 01:10:52 devvm kernel: WARNING: at net/sched/sch_generic.c:261 dev_watchdog+0x26d/0x280() (Not tainted) Jun 14 01:10:52 devvm kernel: Hardware name: VirtualBox Jun 14 01:10:52 devvm kernel: NETDEV WATCHDOG: eth0 (e1000): transmit queue 0 timed out Jun 14 01:10:52 devvm kernel: Modules linked in: vboxsf(U) ipv6 ppdev parport_pc parport microcode sg vboxguest(U) i2c_piix4 i2c_core e1000 snd_intel8x0 snd_ac97_codec ac97_bus snd_seq snd_seq_device snd_pcm snd_timer snd soundcore snd_page_alloc pcnet32 mii ext4 mbcache jbd2 sd_mod crc_t10dif ahci dm_mirror dm_region_hash dm_log dm_mod [last unloaded: scsi_wait_scan] Jun 14 01:10:52 devvm kernel: Pid: 0, comm: swapper Not tainted 2.6.32-279.el6.x86_64 #1 Jun 14 01:10:52 devvm kernel: Call Trace: Jun 14 01:10:52 devvm kernel: <IRQ> [<ffffffff8106b747>] ? warn_slowpath_common+0x87/0xc0 Jun 14 01:10:52 devvm kernel: [<ffffffff8106b836>] ? warn_slowpath_fmt+0x46/0x50 Jun 14 01:10:52 devvm kernel: [<ffffffff814595fd>] ? dev_watchdog+0x26d/0x280 Jun 14 01:10:52 devvm kernel: [<ffffffff81099138>] ? sched_clock_cpu+0xb8/0x110 Jun 14 01:10:52 devvm kernel: [<ffffffff81459390>] ? dev_watchdog+0x0/0x280 Jun 14 01:10:52 devvm kernel: [<ffffffff8107e897>] ? run_timer_softirq+0x197/0x340 Jun 14 01:10:52 devvm kernel: [<ffffffff810a21c0>] ? tick_sched_timer+0x0/0xc0 Jun 14 01:10:52 devvm kernel: [<ffffffff8102b40d>] ? lapic_next_event+0x1d/0x30 Jun 14 01:10:52 devvm kernel: [<ffffffff81073ec1>] ? __do_softirq+0xc1/0x1e0 Jun 14 01:10:52 devvm kernel: [<ffffffff81096c50>] ? hrtimer_interrupt+0x140/0x250 Jun 14 01:10:52 devvm kernel: [<ffffffff8100c24c>] ? call_softirq+0x1c/0x30 Jun 14 01:10:52 devvm kernel: [<ffffffff8100de85>] ? do_softirq+0x65/0xa0 Jun 14 01:10:52 devvm kernel: [<ffffffff81073ca5>] ? irq_exit+0x85/0x90 Jun 14 01:10:52 devvm kernel: [<ffffffff81505be0>] ? smp_apic_timer_interrupt+0x70/0x9b Jun 14 01:10:52 devvm kernel: [<ffffffff8100bc13>] ? apic_timer_interrupt+0x13/0x20 Jun 14 01:10:52 devvm kernel: <EOI> [<ffffffff810387cb>] ? native_safe_halt+0xb/0x10 Jun 14 01:10:52 devvm kernel: [<ffffffff810149cd>] ? default_idle+0x4d/0xb0 Jun 14 01:10:52 devvm kernel: [<ffffffff81009e06>] ? cpu_idle+0xb6/0x110 Jun 14 01:10:52 devvm kernel: [<ffffffff814e433a>] ? rest_init+0x7a/0x80 Jun 14 01:10:52 devvm kernel: [<ffffffff81c21f7b>] ? start_kernel+0x424/0x430 Jun 14 01:10:52 devvm kernel: [<ffffffff81c2133a>] ? x86_64_start_reservations+0x125/0x129 Jun 14 01:10:52 devvm kernel: [<ffffffff81c21438>] ? x86_64_start_kernel+0xfa/0x109 Jun 14 01:10:52 devvm kernel: ---[ end trace 2c7bb984812cf120 ]--- Jun 14 01:10:52 devvm kernel: e1000 0000:00:03.0: eth0: Reset adapter Jun 14 01:10:53 devvm abrtd: Directory 'oops-2013-06-14-01:10:53-1537-0' creation detected Jun 14 01:10:53 devvm abrt-dump-oops: Reported 1 kernel oopses to Abrt Jun 14 01:10:53 devvm abrtd: Can't open file '/var/spool/abrt/oops-2013-06-14-01:10:53-1537-0/uid': No such file or directory Jun 14 01:10:55 devvm kernel: Bridge firewalling registered After this we see for a while, every two minutes: Jun 14 01:14:22 devvm kernel: INFO: task events/0:19 blocked for more than 120 seconds.

• Cache Simulator in C

  - by DuffDuff

  Ok this is only my second question, and it's quite a doozy. It's for a school assignment, but no one (including the TAs) seems to be able to help me. It's kind of a tall order but I'm not sure where else to turn. Essentially the assignment was to make a cache simulator. This version is direct mapping and is actually only a small portion of the whole project, but if I can't even get this down I have no chance with other associativities. I'm posting my whole code because I don't want to make any assumptions about where the problem is. This is the test case: http://www.mediafire.com/?ty5dnihydnw And you run the following command: ./sims 512 direct 32 fifo wt pinatrace.out You're supposed to get: hits: 604037 misses 138349 writes: 239269 reads: 138349 But I get: Hits: 587148 Misses: 155222 Writes: 239261 Reads: 155222 If anyone could at least point me in the right direction it would be greatly appreciated. I've been stuck on this for about 12 hours. #include <stdio.h> #include <stdlib.h> #include <string.h> #include <math.h> struct myCache { int valid; char *tag; char *block; }; /* sim [-h] <cache size> <associativity> <block size> <replace alg> <write policy> <trace file> */ //God willing I come up with a better Hex to Bin convertion that maintains the beginning 0s... void hex2bin(char input[], char output[]) { int i;

• Is it possible to run an ng-switch directly on a select > option

  - by Asok

  Has anyone been able to run an ng-switch on a <select> -> <option> tag, like so?: <select ng-model="form.permitLocality" ng-switch on="localityTypeRadio"> <option ng-switch-when="County" ng-repeat="county in countyList"> {{ county.name }} </option> <option ng-switch-when="City" ng-repeat="city in cityList"> {{ city.name }} </option> <option ng-switch-when="Town" ng-repeat="town in townList"> {{ town.name }} </option> </select> I am not getting any errors or any options (all values verified), I just thought it would save me a couple lines and thought I'd try it. Here is my selector, in case you're curious (value verified): <label class="radio inline"> <input type="radio" name="localityTypeRadio" ng-model="localityTypeRadio" value="County"> County </label> <label class="radio inline"> <input type="radio" name="localityTypeRadio" ng-model="localityTypeRadio" value="City"> City </label> <label class="radio inline"> <input type="radio" name="localityTypeRadio" ng-model="localityTypeRadio" value="Town"> Town </label> This is not a big deal, just didn't know if this was a limitation / not recommended with an ng-switch EDIT I was mistaken when I initially said that nothing was happening (browser caching), there appears to be the correct number of options but the source code shows nothing but white space: <select ng-model="form.permitLocality" class="input-block-level ng-pristine ng-valid" ng-switch="" on="localityTypeRadio" ng-hide="form.permitLocality.length"><option value="? string: ?"></option> <!--

• How to recursively delete some xml elements using XSLT

  - by Monomachus

  Hi, So I got this situation which sucks. I have an XML like this <table border="1" cols="200 100pt 200"> <tr> <td>isbn</td> <td>title</td> <td>price</td> </tr> <tr> <td /> <td /> <td> <span type="champsimple" id="9b297fb5-d12b-46b1-8899-487a2df0104e" categorieid="a1c70692-0427-425b-983c-1a08b6585364" champcoderef="01f12b93-b4c5-401b-9da1-c9385d77e43f"> [prénom] </span> <span type="champsimple" id="e103a6a5-d1be-4c34-8a54-d234179fb4ea" categorieid="a1c70692-0427-425b-983c-1a08b6585364" champcoderef="01f12b93-b4c5-401b-9da1-c9385d77e43f">[nom]</span> <span></span> </td> </tr> <tr></tr> <tr> <td></td> <td>Phill It in</td> </tr> <tr> <table id="cas1"> <tr> <td ></td> <td >foo</td> </tr> <tr> <td >bar</td> <td >boo</td> </tr> </table> </tr> <tr> <table id="cas2"> <tr> <td ></td> <td >foo</td> </tr> <tr> <td ></td> <td >boo</td> </tr> </table> </tr> <tr> <table id="cas3"> <tr> <td >bar</td> <td ></td> </tr> <tr> <td >foo</td> <td >boo</td> </tr> </table> </tr> <tr> <table id="cas4"> <tr> <td /> <td /> </tr> <tr> <td>foo</td> <td>boo</td> </tr> </table> </tr> <table id="cas4"> <tr> <td /> <td /> </tr> <tr> <td>foo</td> <td>boo</td> </tr> </table> <tr> <td /> <td /> </tr> </table> Now the question is how would I recursively delete all empty td, tr and table elements? Now I use this XSLT <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output omit-xml-declaration="yes" indent="yes"/> <xsl:strip-space elements="*" /> <xsl:template match="node()|@*"> <xsl:copy> <xsl:apply-templates select="node()|@*"/> </xsl:copy> </xsl:template> <xsl:template match="td[not(node())]" /> <xsl:template match="tr[not(node())]" /> <xsl:template match="table[not(node())]" /> </xsl:stylesheet> But it doesn't do very well. After I delete td, a tr becomes empty but it doesn't handle that. Too bad. See the table element with "cas4". <table border="1" cols="200 100pt 200"> <tr> <td>isbn</td> <td>title</td> <td>price</td> </tr> <tr> <td> <span type="champsimple" id="9b297fb5-d12b-46b1-8899-487a2df0104e" categorieid="a1c70692-0427-425b-983c-1a08b6585364" champcoderef="01f12b93-b4c5-401b-9da1-c9385d77e43f"> [prénom] </span> <span type="champsimple" id="e103a6a5-d1be-4c34-8a54-d234179fb4ea" categorieid="a1c70692-0427-425b-983c-1a08b6585364" champcoderef="01f12b93-b4c5-401b-9da1-c9385d77e43f">[nom]</span> <span /> </td> </tr> <tr> <td>Phill It in</td> </tr> <tr> <table id="cas1"> <tr> <td>foo</td> </tr> <tr> <td>bar</td> <td>boo</td> </tr> </table> </tr> <tr> <table id="cas2"> <tr> <td>foo</td> </tr> <tr> <td>boo</td> </tr> </table> </tr> <tr> <table id="cas3"> <tr> <td>bar</td> </tr> <tr> <td>foo</td> <td>boo</td> </tr> </table> </tr> <tr> <table id="cas4"> <tr /> <tr> <td>foo</td> <td>boo</td> </tr> </table> </tr> <table id="cas4"> <tr /> <tr> <td>foo</td> <td>boo</td> </tr> </table> <tr /> </table> How would you solve this problem?

I thought any call to malloc or calloc allocated heap space; there is no other variable allocated here, right? Is it possible there's another allocation going on (the offending stack allocation) that I'm not seeing? You asked to see the code, here goes: /* Copyright 2010 Joel J.

• Google Maps API v3 - Different markers/labels on different zoom levels

  - by krikara

  I was wondering if it is possible that Google has a feature to view different markers on different zoom levels. For example, on zoom level 1, I want one marker over China with the label saying "5". And as the user zooms in, lets say on zoom level 4, I want the previous marker and label to disappear. And I want to have 5 new markers/labels, each on a different city in China all saying "1". Thus China will say a number and all the cities in China will say numbers adding up to China's number. The key concept I am trying to figure out here is how to hide markers and labels based on zoom levels. A constraint for me is that I am living in China currently where google is censored, so a lot of online documents are censored for me, including many of google's documentations. Here is my code thus far <!DOCTYPE html> <html> <head> <meta name="viewport" content="initial-scale=1.0, user-scalable=no" /> <title>TM China</title> <style type="text/css"> html, body, #map_canvas { margin: 0;

And when I copy the source code directly to my computer and replace all the icons with markers, the markers still don't appear. I can't seem to figure how to make markers appear using the marker Manager. http://google-maps-utility-library-v3.googlecode.com/svn/tags/markermanager/1.0/examples/weather_map.html

• o write a C++ program to encrypt and decrypt certain codes.

  - by Amber

  Step 1: Write a function int GetText(char[],int); which fills a character array from a requested file. That is, the function should prompt the user to input the filename, and then read up to the number of characters given as the second argument, terminating when the number has been reached or when the end of file is encountered. The file should then be closed. The number of characters placed in the array is then returned as the value of the function. Every character in the file should be transferred to the array. Whitespace should not be removed. When testing, assume that no more than 5000 characters will be read. The function should be placed in a file called coding.cpp while the main will be in ass5.cpp. To enable the prototypes to be accessible, the file coding.h contains the prototypes for all the functions that are to be written in coding.cpp for this assignment. (You may write other functions. If they are called from any of the functions in coding.h, they must appear in coding.cpp where their prototypes should also appear. Do not alter coding.h. Any other functions written for this assignment should be placed, along with their prototypes, with the main function.) Step 2: Write a function int SimplifyText(char[],int); which simplifies the text in the first argument, an array containing the number of characters as given in the second argument, by converting all alphabetic characters to lower case, removing all non-alpha characters, and replacing multiple whitespace by one blank. Any leading whitespace at the beginning of the array should be removed completely. The resulting number of characters should be returned as the value of the function. Note that another array cannot appear in the function (as the file does not contain one). For example, if the array contained the 29 characters "The 39 Steps" by John Buchan (with the " appearing in the array), the simplified text would be the steps by john buchan of length 24. The array should not contain a null character at the end. Step 3: Using the file test.txt, test your program so far. You will need to write a function void PrintText(const char[],int,int); that prints out the contents of the array, whose length is the second argument, breaking the lines to exactly the number of characters in the third argument. Be warned that, if the array contains newlines (as it would when read from a file), lines will be broken earlier than the specified length. Step 4: Write a function void Caesar(const char[],int,char[],int); which takes the first argument array, with length given by the second argument and codes it into the third argument array, using the shift given in the fourth argument. The shift must be performed cyclicly and must also be able to handle negative shifts. Shifts exceeding 26 can be reduced by modulo arithmetic. (Is C++'s modulo operations on negative numbers a problem here?) Demonstrate that the test file, as simplified, can be coded and decoded using a given shift by listing the original input text, the simplified text (indicating the new length), the coded text and finally the decoded text. Step 5: The permutation cypher does not limit the character substitution to just a shift. In fact, each of the 26 characters is coded to one of the others in an arbitrary way. So, for example, a might become f, b become q, c become d, but a letter never remains the same. How the letters are rearranged can be specified using a seed to the random number generator. The code can then be decoded, if the decoder has the same random number generator and knows the seed. Write the function void Permute(const char[],int,char[],unsigned long); with the same first three arguments as Caesar above, with the fourth argument being the seed. The function will have to make up a permutation table as follows: To find what a is coded as, generate a random number from 1 to 25. Add that to a to get the coded letter. Mark that letter as used. For b, generate 1 to 24, then step that many letters after b, ignoring the used letter if encountered. For c, generate 1 to 23, ignoring a or b's codes if encountered. Wrap around at z. Here's an example, for only the 6 letters a, b, c, d, e, f. For the letter a, generate, from 1-5, a 2. Then a - c. c is marked as used. For the letter b, generate, from 1-4, a 3. So count 3 from b, skipping c (since it is marked as used) yielding the coding of b - f. Mark f as used. For c, generate, from 1-3, a 3. So count 3 from c, skipping f, giving a. Note the wrap at the last letter back to the first. And so on, yielding a - c b - f c - a d - b (it got a 2) e - d f - e Thus, for a given seed, a translation table is required. To decode a piece of text, we need the table generated to be re-arranged so that the right hand column is in order. In fact you can just store the table in the reverse way (e.g., if a gets encoded to c, put a opposite c is the table). Write a function called void DePermute(const char[],int,char[], unsigned long); to reverse the permutation cypher. Again, test your functions using the test file. At this point, any main program used to test these functions will not be required as part of the assignment. The remainder of the assignment uses some of these functions, and needs its own main function. When submitted, all the above functions will be tested by the marker's own main function. Step 6: If the seed number is unknown, decoding is difficult. Write a main program which: (i) reads in a piece of text using GetText; (ii) simplifies the text using SimplifyText; (iii) prints the text using PrintText; (iv) requests two letters to swap. If we think 'a' in the text should be 'q' we would type aq as input. The text would be modified by swapping the a's and q's, and the text reprinted. Repeat this last step until the user considers the text is decoded, when the input of the same letter twice (requesting a letter to be swapped with itself) terminates the program. Step 7: If we have a large enough sample of coded text, we can use knowledge of English to aid in finding the permutation. The first clue is in the frequency of occurrence of each letter. Write a function void LetterFreq(const char[],int,freq[]); which takes the piece of text given as the first two arguments (same as above) and returns in the 26 long array of structs (the third argument), the table of the frequency of the 26 letters. This frequency table should be in decreasing order of popularity. A simple Selection Sort will suffice. (This will be described in lectures.) When printed, this summary would look something like v x r s z j p t n c l h u o i b w d g e a q y k f m 168106 68 66 59 54 48 45 44 35 26 24 22 20 20 20 17 13 12 12 4 4 1 0 0 0 The formatting will require the use of input/output manipulators. See the header file for the definition of the struct called freq. Modify the program so that, before each swap is requested, the current frequency of the letters is printed. This does not require further calls to LetterFreq, however. You may use the traditional order of regular letter frequencies (E T A I O N S H R D L U) as a guide when deciding what characters to exchange. Step 8: The decoding process can be made more difficult if blank is also coded. That is, consider the alphabet to be 27 letters. Rewrite LetterFreq and your main program to handle blank as another character to code. In the above frequency order, space usually comes first.

• HTML/jQuery/CSS Drop Down Menu Issue / Safari
