• Pass PHP variables without being seen when working with a database generated list

  - by Wilcoholic

  Looking for any help regarding the problem. Here's the deal: I have a database that has a teams table and it contains team_id. On one of my pages, I generate a list of links that contain the team_id of the creator in their get URL. I need the team_id on the next page but can't figure out how to pass it through any other way. Using a form and POST isn't an option because this method would only pass through the last links data on the list. Storing in a session isn't an option either because there is no way to discretely pass the the variables I need to a function to set the session variables. I have tried and it can pretty easily be viewed from viewing the source code. So here's some sample code to see exactly what I'm dealing with. <? if(mysql_num_rows($result2)>0){ ?> <a class="fltrt btn btn-danger btn-small" onclick="test()" href="acceptmatch-exec.php?match_id=<?php echo $match_id; ?>&team_id=<?php echo $team_id;?>&action=cancel">Cancel Match</a> <?}else{?> <a class="fltrt btn btn-success btn-small" href="acceptmatch-exec.php?match_id=<?php echo $match_id; ?>&team_id=<?php echo $team_id;?>&action=accept">Accept Match</a> <?} ?> The code above is generated multiple times on a page via a while loop that was excluded. I want to pass the match_id and team_id variables without being seen anywhere. If I made this a form, it wouldn't pass the correct variables unless there is only one result at the time (not likely). I'm sure there has to be an easy method that is eluding me, so please share thoughts on how to solve this. I feel as though I am not explaining it well enough, but it's not really easy to explain. I basically want something that works like GET but acts like POST and can be hidden from people viewing source code or link locations. Thanks

• How to calculate where bullet hits

  - by lkjoel

  I have been trying to write an FPS in C/X11/OpenGL, but the issue that I have encountered is with calculating where the bullet hits. I have used a horrible technique, and it only sometimes works: pos size, p; size.x = 0.1; size.z = 0.1; // Since the game is technically top-down (but in a 3D perspective) // Positions are in X/Z, no Y float f; // Counter float d = FIRE_MAX + 1 /* Shortest Distance */, d1 /* Distance being calculated */; x = 0; // Index of object to hit for (f = 0.0; f < FIRE_MAX; f += .01) { // Go forwards p.x = player->pos.x + f * sin(toRadians(player->rot.x)); p.z = player->pos.z - f * cos(toRadians(player->rot.x)); // Get all objects that collide with the current position of the bullet short* objs = _colDetectGetObjects(p, size, objects); for (i = 0; i < MAX_OBJECTS; i++) { if (objs[i] == -1) { continue; } // Check the distance between the object and the player d1 = sqrt( pow((objects[i].pos.x - player->pos.x), 2) + pow((objects[i].pos.z - player->pos.z), 2)); // If it's closer, set it as the object to hit if (d1 < d) { x = i; d = d1; } } // If there was an object, hit it if (x > 0) { hit(&objects[x], FIRE_DAMAGE, explosions, currtime); break; } } It just works by making a for-loop and calculating any objects that might collide with where the bullet currently is. This, of course, is very slow, and sometimes doesn't even work. What would be the preferred way to calculate where the bullet hits? I have thought of making a line and seeing if any objects collide with that line, but I have no idea how to do that kind of collision detection. EDIT: I guess my question is this: How do I calculate the nearest object colliding in a line (that might not be a straight 45/90 degree angle)? Or are there any simpler methods of calculating where the bullet hits? The bullet is sort of like a laser, in the sense that gravity does not affect it (writing an old-school game, so I don't want it to be too realistic)

• Wake up thread blocked on accept() call

  - by selbie

  Sockets on Linux question I have a worker thread that is blocked on an accept() call. It simply waits for an incoming network connection, handles it, and then returns to listening for the next connection. When it is time for the program to exit, how do I signal this network worker thread (from the main thread) to return from the accept() call while still being able to gracefully exit its loop and handle it's cleanup code. Some things I tried: 1. pthread_kill to send a signal. Feels kludgy to do this, plus it doesn't reliably allow the thread to do it's shutdown logic. Also makes the program terminate as well. I'd like to avoid signals if at all possible. pthread_cancel. Same as above. It's a harsh kill on the thread. That, and the thread may be doing something else. Closing the listen socket from the main thread in order to make accept() abort. This doesn't reliably work. Some constraints: If the solution involves making the listen socket non-blocking, that is fine. But I don't want to accept a solution that involves the thread waking up via a select call every few seconds to check the exit condition. The thread condition to exit may not be tied to the process exiting. Essentially, the logic I am going for looks like this. void* WorkerThread(void* args) { DoSomeImportantInitialization(); // initialize listen socket and some thread specific stuff while (HasExitConditionBeenSet()==false) { listensize = sizeof(listenaddr); int sock = accept(listensocket, &listenaddr, &listensize); // check if exit condition has been set using thread safe semantics if (HasExitConditionBeenSet()) { break; } if (sock < 0) { printf("accept returned %d (errno==%d)\n", sock, errno); } else { HandleNewNetworkCondition(sock, &listenaddr); } } DoSomeImportantCleanup(); // close listen socket, close connections, cleanup etc.. return NULL; } void SignalHandler(int sig) { printf("Caught CTRL-C\n"); } void NotifyWorkerThreadToExit(pthread_t thread_handle) { // signal thread to exit } int main() { void* ptr_ret= NULL; pthread_t workerthread_handle = 0; pthread_create(&workerthread, NULL, WorkerThread, NULL); signal(SIGINT, SignalHandler); sleep((unsigned int)-1); // sleep until the user hits ctrl-c printf("Returned from sleep call...\n"); SetThreadExitCondition(); // sets global variable with barrier that worker thread checks on // this is the function I'm stalled on writing NotifyWorkerThreadToExit(workerthread_handle); // wait for thread to exit cleanly pthread_join(workerthread_handle, &ptr_ret); DoProcessCleanupStuff(); }

• No warning from gcc when function definition in linked source different from function prototype in h

  - by c_c

  Hi, I had a problem with a part of my code, which after some iterations seemed to read NaN as value of a int of a struct. I think I found the error, but am still wondering why gcc (version 3.2.3 on a embedded Linux with busybox) did not warn me. Here are the important parts of the code: A c file and its header for functions to acquire data over USB: // usb_control.h typedef struct{ double mean; short *values; } DATA_POINTS; typedef struct{ int size; DATA_POINTS *channel1; //....7 more channels } DATA_STRUCT; DATA_STRUCT *create_data_struct(int N); // N values per channel int free_data_struct(DATA_STRUCT *data); int aqcu_data(DATA_STRUCT *data, int N); A c and header file with helper function (math, bitshift,etc...): // helper.h int mean(DATA_STRUCT *data); // helper.c (this is where the error is obviously) double mean(DATA_STRUCT *data) { // sum in for loop data->channel1->mean = sum/data->N; // ...7 more channels // a printf here displayed the mean values corretly } The main file // main.c #include "helper.h" #include "usb_control.h" // Allocate space for data struct DATA_STRUCT *data = create_data_struct(N); // get data for different delays for (delay = 0; delay < 500; delay += pw){ acqu_data(data, N); mean(data); // printf of the mean values first is correct. Than after 5 iterations // it is always NaN for channel1. The other channels are displayed correctly; } There were no segfaults nor any other missbehavior, just the NaN for channel1 in the main file. After finding the error, which was not easy, it was of course east to fix. The return type of mean(){} was wrong in the definition. Instead of double mean() it has to be int mean() as the prototype defines. When all the functions are put into one file, gcc warns me that there is a redefinition of the function mean(). But as I compile each c file seperately and link them afterwards gcc seems to miss that. So my questions would be. Why didn't I get any warnings, even non with gcc -Wall? Or is there still another error hidden which is just not causing problems now? Regards, christian

• I can I separate multiple logical pages in a text file I create in Perl?

  - by Micah

  So far, I've been successful with generating output to individual files by opening a file for output as part of outer loop and closing it after all output is written. I had used a counting variable ($x) and appended .txt onto it to create a filename, and had written it to the same directory as my perl script. I want to step the code up a bit, prompt for a file name from the user, open that file once and only once, and write my output one "printed letter" per page. Is this possible in plain text? From what I understand, chr(12) is an ascii line feed character and will get me close to what I want, but is there a better way? Thanks in advance, guys. :) sub PersonalizeLetters{ print "\n\n Beginning finalization of letters..."; print "\n\n I need a filename to save these letters to."; print "\n Filename > "; $OutFileName = <stdin>; chomp ($OutFileName); open(OutFile, ">$OutFileName"); for ($x=0; $x<$NumRecords; $x++){ $xIndex = (6 * $x); $clTitle = @ClientAoA[$xIndex]; $clName = @ClientAoA[$xIndex+1]; #I use this 6x multiplier because my records have 6 elements. #For this routine I'm only interested in name and title. #Reset OutLetter array #Midletter has other merged fields that aren't specific to who's receiving the letter. @OutLetter = @MiddleLetter; for ($y=0; $y<=$ifLength; $y++){ #Step through line by line and insert the name. $WorkLine = @OutLetter[$y]; $WorkLine =~ s/\[ClientTitle\]/$clTitle/; $WorkLine =~ s/\[ClientName\]/$clName/; @OutLetter[$y] = $WorkLine; } print OutFile "@OutLetter"; #Will chr(12) work here, or is there something better? print OutFile chr(12); $StatusX = $x+1; print "Writing output $StatusX of $NumRecords... \n\n"; } close(OutFile); }

• PHP Array Not Working in Function

  - by lemonpole

  Hello all. I'm currently experimenting with arrays in PHP, and I created a fake environment where a team's information will be displayed. $t1 = array ( "basicInfo" => array ( "The Sineps", "December 25, 2010", "lemonpole" ), "overallRecord" => array (0, 0, 0, 0), "overallSeasons" => array ( 1 => array (14, 0, 0), 2 => array (9, 5, 2), 3 => array (12, 4, 0), 4 => array (3, 11, 2) ), "games" => array ( "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />", "<img src=\"images/cs.gif\" alt=\"Counter-Strike\" />" ), "seasonHistory" => array ( "Season I", "Season II", "Season III", "Season IV" ), "divisions" => array ( "Open", "Main", "Main", "Invite" ) ); // Displays the seasons the team has been in along // with the record of each season. function seasonHistory() { // Make array variable local-scope. global $t1; // Count the number of seasons. $numrows = count($t1["seasonHistory"]); // Loop through all the variables until // it reaches the last entry made and display // each item seperately. for($v = 0; $v <= $numrows; $v++) { // Echo each season. echo "<tr><td>{$t1["games"][$v]}</td>"; echo "<td>{$t1["seasonHistory"][$v]}</td>"; echo "<td>{$t1["divisions"][$v]}</td></tr>"; } } I have tested several possible problems out and after narrowing them down I have come down to one conclusion and that is my function is not connecting to the array for some reason. I don't know what else to do because I thought making the array global would fix that problem. What works: I can echo $t1["games"][0] on the page I need it to display and it gives me the content. I tried echo $t1["games"][0] INSIDE the function and then calling the function and it doesn't display anything.

• Change xml attribute in foreach statement c#

  - by user1913479

  I need to save XML-attribute value in a database, using information if checkbox is checked. If checkbox is checked, the attribute value is "TRUE", otherwise it's false. When I use foreach statement, the last enumerated value is usually assigned. Here is the part of my code: XmlAttribute xmlAttribute = xmlDoc.CreateAttribute("BooleanValue"); foreach (string value in list) //list is a List<object> { XmlNode xmlNode = xmlDoc.CreateNode(XmlNodeType.Element, "VALUE", ""); if (checkBox1.Checked || checkBox2.Checked || checkBox3.Checked) xmlAttribute.Value = "TRUE"; if (!checkBox1.Checked || !checkBox2.Checked || !checkBox3.Checked) xmlAttribute.Value = "FALSE"; xmlNode.Attributes.Append(xmlAttribute); xmlNode.InnerText = val; childNode.AppendChild(xmlNode); } When I run my application, I get an XML attribute xmlAttribute "FALSE" value anyway. What I need to have: I need to have the following XML: <ROOT><NODE><VALUE ATTRIBUTE="TRUE">Value 1</VALUE></NODE> <NODE><VALUE ATTRIBUTE="TRUE">Value 2</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 3</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 4</VALUE></NODE> <NODE><VALUE ATTRIBUTE="TRUE">Value 5</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 6</VALUE></NODE> </ROOT> What I actually get: <ROOT><NODE><VALUE ATTRIBUTE="FALSE">Value 1</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 2</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 3</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 4</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 5</VALUE></NODE> <NODE><VALUE ATTRIBUTE="FALSE">Value 6</VALUE></NODE> </ROOT> Because in C# FALSE value is stayed at last position in foreach loop The question is: how do I do to assign the correct values of my attribute. Thanks

• Check Avaibility of a page before loading using jquery/ajax

  - by overcomer

  Is it possible check the Accessibility of a page before loading it? I have a form, running on mobile device using wireless connection. The problem is: not always this connection is avaible and i would like to alert the user when is doing a submit or an unload of the page. The problem is that the page contains elements doing redirect like this: <input type="button" value="MyText" onClick="script1;script2;...window.location='mylocation" /> If the user click on this button and the server is not achievable, i will recive some undesiderable errors. Also if I want to generalize my script i do not know the value of "mylocation" previously. The page contains elements to submit the Form also: <input type="submit" name="SUBMIT" value="MyValue" onClick="return eval('validationForm()')" /> For the submitting I'm using the ajaxForm plugin and it works quite well. This is a snippet of code: Thanks to your answer I found the solution to the problem. That's the code: function checkConnection(u,s){ $.ajax({ url:u, cache:false, timeout:3000, error: function(jqXHR, textStatus) { alert("Request failed: " + textStatus ); }, success: function() { eval(s); } }); } $(document).ready(function() { // part of the function that checks buttons with redirect // for any input that contain a redirect on onClick attribute ("window.locarion=") $("input[type=button]").each(function(){ var script = $(this).attr("onClick"); var url = ""; var position = script.indexOf("window.location") ; if (position >= 0) { // case of redirect url = script.substring(position+17, script.lenght); url = url.split("\'")[0]; url = "\'"+url+"\'"; // that's my url script = "\""+script+"\""; // that's the complete script $(this).attr("onClick","checkConnection("+url+","+script+")"); } }); // part of the function that checks the submit buttons (using ajaxForm plugin) var is_error = false; var options = { error: function() { if (alert("Error Message")==true) { } is_error = true; }, target: window.document, replaceTarget: is_error, timeout: 3000 }; $("#myForm").ajaxForm(options); }); I hope that this will be usefull.

• Manipulating values from database table with php

  - by charliecodex23

  I currently have 5 tables in MySQL database. Some of them share foreign keys and are interdependent of each other. I am displaying classes accordingly to their majors. Each class is taught during the fall, spring or all_year. In my database I have a table named semester which has an id, year, and semester fields. The semester field in particular is a tinyint that has three values 0, 1, 2. This signifies the fall, spring or all_year. When I display the query instead of having it show 0 or 1 or 2 can I have it show fall, spring etc? Extra: How can I add space to the end of each loop so the data doesn't look clustered?

• Calling a webservice synchronously from a Silverlight 3 application?

  - by Lasse V. Karlsen

  I am trying to reuse some .NET code that performs some calls to a data-access-layer type service. I have managed to package up both the input to the method and the output from the method, but unfortunately the service is called from inside code that I really don't want to rewrite in order to be asynchronous. Unfortunately, the webservice code generated in Silverlight only produces asynchronous methods, so I was wondering if anyone had working code that managed to work around this? I tried the recipe found here: The Easy Way To Synchronously Call WCF Services In Silverlight, but unfortunately it times out and never completes the call. Or rather, what seems to happen is that the completed event handler is called, but only after the method returns. I am suspecting that the event handler is called from a dispatcher or similar, and since I'm blocking the main thread here, it never completes until the code is actually back into the GUI loop. Or something like that. Here's my own version that I wrote before I found the above recipe, but it suffers from the same problem: public static object ExecuteRequestOnServer(Type dalInterfaceType, string methodName, object[] arguments) { string securityToken = "DUMMYTOKEN"; string input = "DUMMYINPUT"; object result = null; Exception resultException = null; object evtLock = new object(); var evt = new System.Threading.ManualResetEvent(false); try { var client = new MinGatServices.DataAccessLayerServiceSoapClient(); client.ExecuteRequestCompleted += (s, e) => { resultException = e.Error; result = e.Result; lock (evtLock) { if (evt != null) evt.Set(); } }; client.ExecuteRequestAsync(securityToken, input); try { var didComplete = evt.WaitOne(10000); if (!didComplete) throw new TimeoutException("A data access layer web service request timed out (" + dalInterfaceType.Name + "." + methodName + ")"); } finally { client.CloseAsync(); } } finally { lock (evtLock) { evt.Close(); evt = null; } } if (resultException != null) throw resultException; else return result; } Basically, both recipes does this: Set up a ManualResetEvent Hook into the Completed event The event handler grabs the result from the service call, and signals the event The main thread now starts the web service call asynchronously It then waits for the event to become signalled However, the event handler is not called until the method above has returned, hence my code that checks for evt != null and such, to avoid TargetInvocationException from killing my program after the method has timed out. Does anyone know: ... if it is possible at all in Silverlight 3 ... what I have done wrong above?

• stringindexoutofbounds with currency converter java program

  - by user1795926

  I am have trouble with a summary not showing up. I am supposed to modify a previous Java assignment by by adding an array of objects. Within the loop, instantiate each individual object. Make sure the user cannot keep adding another Foreign conversion beyond your array size. After the user selects quit from the menu, prompt if the user want to display a summary report. If they select ‘Y’ then, using your array of objects, display the following report: Item Conversion Dollars Amount 1 Japanese Yen 100.00 32,000.00 2 Mexican Peso 400.00 56,000.00 3 Canadian Dollar 100.00 156.00 etc. Number of Conversions = 3 There are no errors when I compile..but when I run the program it is fine until I hit 0 to end the conversion and have it ask if i want to see a summary. This error displays: Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 0 at java.lang.String.charAt(String.java:658) at Lab8.main(Lab8.java:43) my code: import java.util.Scanner; import java.text.DecimalFormat; public class Lab8 { public static void main(String[] args) { final int Max = 10; String a; char summary; int c = 0; Foreign[] Exchange = new Foreign[Max]; Scanner Keyboard = new Scanner(System.in); Foreign.opening(); do { Exchange[c] = new Foreign(); Exchange[c].getchoice(); Exchange[c].dollars(); Exchange[c].amount(); Exchange[c].vertical(); System.out.println("\n" + Exchange[c]); c++; System.out.println("\n" + "Please select 1 through 4, or 0 to quit" + >"\n"); c= Keyboard.nextInt(); } while (c != 0); System.out.print("\nWould you like a summary of your conversions?

• Drupal's profile_save_profile Doesn't Work in hook_cron, When Run by the Server's cron

  - by anschauung

  I have a problem with the following implementation of hook_cron in Drupal 6.1.3. The script below runs exactly as expected: it sends a welcome letter to new members, and updates a hidden field in their profile to designate that the letter has been sent. There are no errors in the letter, all new members are accounted for, etc. The problem is that the last line -- updating the profile -- doesn't seem to work when Drupal cron is invoked by the 'real' cron on the server. When I run cron manually (such as via /admin/reports/status/run-cron) the profile fields get updated as expected. Any suggestions as to what might be causing this? (Note, since someone will suggest it: members join by means outside of Drupal, and are uploaded to Drupal nightly, so Drupal's built-in welcome letters won't work (I think).) <?php function foo_cron() { // Find users who have not received the new member letter, // and send them a welcome email // Get users who have not recd a message, as per the profile value setting $pending_count_sql = "SELECT COUNT(*) FROM {profile_values} v WHERE (v.value = 0) AND (v.fid = 7)"; //fid 7 is the profile field for profile_intro_email_sent if (db_result(db_query($pending_count_sql))) { // Load the message template, since we // know we have users to feed into it. $email_template_file = "/home/foo/public_html/drupal/" . drupal_get_path('module', 'foo') .

• How to avoid my script to freeze

  - by jemz

  I have socket server script that continuously running listening for the GPS device that runs in PHP CLI,my problem is that my socket will freeze if it executes long time,how do I prevent this so that my script will not freeze.I have no idea on this socket.this is the first time that I use socket connection. I appreciate someone can help my problem. <?php error_reporting(-1); ini_set('display_errors', 1); set_time_limit (0); $address_server = 'xxx.xxx.xx.xx'; $port_server = xxxx; $isTrue = true; socketfunction($address_server,$port_server,$isTrue); function socketfunction($address,$port,$done){ $sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); socket_set_option($sock, SOL_SOCKET, SO_REUSEADDR, 1); socket_bind($sock, $address, $port); socket_listen($sock); $clients = array($sock); while ($done ) { $file = fopen('txt.log','a'); $read = $clients; $write = NULL; $except = NULL; $tv_sec = 0; if (socket_select($read, $write , $except, $tv_sec) < 1){ continue; } // checking client if (in_array($sock, $read)) { $clients[] = $newsock = socket_accept($sock); $key = array_search($sock, $read); unset($read[$key]); } //handle client for reading foreach ($read as $read_sock) { $data = @socket_read($read_sock, 1024, PHP_NORMAL_READ); if ($data === false) { $key = array_search($read_sock, $clients); unset($clients[$key]); echo "client disconnected.\n"; echo "Remaining ".(count($clients) - 1)."client(s) connected\r\n"; continue; } $data = trim($data); if (!empty($data)) { echo("Returning stripped input\n"); fwrite($file,$data."\n"); } } // end of reading foreach fclose($file); }//end while socket_close($sock); } ?> Thank you in advance.

• Command prompt in debug mode for Eclipse? (OpenCV + Eclipse + Win7)

  - by Tony

  I am a beginner for Eclipse. I now have Eclipse C/C++ IDE with OpenCV library running on Windows 7. So far it works after spending hours trying to get it running. But then I realize that Eclipse does not pop up a command prompt as VS2010 does while debugging. And moreover Eclipse's debug mode is just stuck in there and refuse to output anything. But if the code doesn't involve the OpenCV things it works again. Below is the code I use for testing. It captures images from webcam and output it to the screen. The infinite loop (until you press 'q') makes sure it constantly grabs new inputs from the camera. I browsed through the workspace and run the exe just compiled and it worked flawlessly. So I don't think there's anything wrong in the code (it's an example code anyway In brief, can I just pop up a command prompt window in debug mode? And why is Eclipse console stuck when the code involves some OpenCV functions? #include <stdio.h> #include <stdlib.h> #include <tchar.h> #include <cv.h> #include <cxcore.h> #include <highgui.h> #include <iostream> int _tmain(int argc, _TCHAR* argv[]) { CvCapture *capture = 0; IplImage *frame = 0; int key = 0; /* initialize camera */ capture = cvCaptureFromCAM( 0 ); /* always check */ if ( !capture ) { printf("Cannot open initialize webcam!\n"); return 1; } /* create a window for the video */ cvNamedWindow( "result", CV_WINDOW_AUTOSIZE ); while( key != 'q' ) { /* get a frame */ frame = cvQueryFrame( capture ); /* always check */ if( !frame ) break; /* display current frame */ cvShowImage( "result", frame ); /* exit if user press 'q' */ key = cvWaitKey( 1 ); } /* free memory */ cvDestroyWindow( "result" ); cvReleaseCapture( &capture ); return 0; }

• Where can I find "canonical" sample programs that give quick refreshers for any given language? [on hold]

  - by acheong87

  Note to those close-voting this question: I understand this isn't a conventional programming question and I can agree with the reasoning that it's in the subjective domain (like best-of lists). In other ways though I think it's appropriate because, though it's not a "a specific programming problem," nor concerning "a software algorithm", nor (strictly) concerning "software tools commonly used by programmers", I think it is a "practical, answerable [problem that is] unique to the programming profession," and I think it is "based on an actual [problem I] face." I've been wanting this for some time now, because both approaches of (a) Googling for samples as I write every other line of code and (b) just winging it and seeing what errors crop up, distract me from coding efficiently. This note will be removed if the question gains popularity; this question will be deleted otherwise. I spend most of my time developing in C++, PHP, or Javascript, and every once in a while I have to do something in, say, VBA. In those times, it'd be convenient if I could just put up some sample code on a second monitor, something in between a cheat sheet (often too compact; and doesn't resemble anything that could actually compile/run), and a language reference (often too verbose, or segmented; requires extra steps to search or click through an index), so I can just glance at it and recall things, like how to loop through non-empty cells in a column. I think there's a hidden benefit to seeing formed code, that triggers the right spots in our brains to get back into a language we only need to brush up on. Similar in spirit is how http://ideone.com lets you click "Template" in any given language so you can get started without even doing a search. That template alone tells a lot, sometimes! Case-sensitivity, whitespace conventions, identifier conventions, the spelling of certain types, etc. I couldn't find a resource that pulled together such samples, so if there indeed doesn't exist such a repository, I was hoping this question would inspire professionals and experts to contribute links to the most useful sample code they've used for just this purpose: a keep-on-the-side, form-as-well-as-content, compilable/executable, reminder of a language's basic and oft-used features. Personally I am interested in seeing "samplers" for: VBA, Perl, Python, Java, C# (though for some of these autocompleters in Eclipse, Visual Studio, etc. help enough), awk, and sed. I'm tagging c++, php, and javascript because these are languages for which I'd best be able to evaluate whether proffered sample code matches what I had in mind.

• Java Sorting "queue" list based on DateTime and Z Position (part of school project)

  - by Kuchinawa

  For a school project i have a list of 50k containers that arrive on a boat. These containers need to be sorted in a list in such a way that the earliest departure DateTimes are at the top and the containers above those above them. This list then gets used for a crane that picks them up in order. I started out with 2 Collection.sort() methods: 1st one to get them in the right XYZ order Collections.sort(containers, new Comparator<ContainerData>() { @Override public int compare(ContainerData contData1, ContainerData contData2) { return positionSort(contData1.getLocation(),contData2.getLocation()); } }); Then another one to reorder the dates while keeping the position in mind: Collections.sort(containers, new Comparator<ContainerData>() { @Override public int compare(ContainerData contData1, ContainerData contData2) { int c = contData1.getLeaveDateTimeFrom().compareTo(contData2.getLeaveDateTimeFrom()); int p = positionSort2(contData1.getLocation(), contData2.getLocation()); if(p != 0) c = p; return c; } }); But i never got this method to work.. What i got working now is rather quick and dirty and takes a long time to process (50seconds for all 50k): First a sort on DateTime: Collections.sort(containers, new Comparator<ContainerData>() { @Override public int compare(ContainerData contData1, ContainerData contData2) { return contData1.getLeaveDateTimeFrom().compareTo(contData2.getLeaveDateTimeFrom()); } }); Then a correction function that bumps top containers up: containers = stackCorrection(containers); private static List<ContainerData> stackCorrection(List<ContainerData> sortedContainerList) { for(int i = 0; i < sortedContainerList.size(); i++) { ContainerData current = sortedContainerList.get(i); // 5 = Max Stack (0 index) if(current.getLocation().getZ() < 5) { //Loop through possible containers above current for(int j = 5; j > current.getLocation().getZ(); --j) { //Search for container above for(int k = i + 1; k < sortedContainerList.size(); ++k) if(sortedContainerList.get(k).getLocation().getX() == current.getLocation().getX()) { if(sortedContainerList.get(k).getLocation().getY() == current.getLocation().getY()) { if(sortedContainerList.get(k).getLocation().getZ() == j) { //Found -> move container above current sortedContainerList.add(i, sortedContainerList.remove(k)); k = sortedContainerList.size(); i++; } } } } } } return sortedContainerList; } I would like to implement this in a better/faster way. So any hints are appreciated. :)

• PHP send batch email [closed]

  - by qalbiol

  Possible Duplicate: Sending mass email using PHP I have a PHP script that sends an individual email to all users in my DB, such as a monthly / weekly newsletter. The code I am using goes as follows: $subject = $_POST['subject']; $message = $_POST['message']; // Get all the mailing list subscribers. $query = $db->prepare("SELECT * FROM maildb"); $query->execute(); // Loop through all susbcribers, and send and individual email. foreach ($query as $row) { // Setting maximum time limit to infinite. set_time_limit(0); $newMessage = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> </head> <body>'; // Search for the [unsubscribe] tag and replace it with a URL for the user to unsubscribe $newMessage .= str_replace("[unsubscribe]", "<a href='".BASE_URL."unsubscribe/".$row['hash']."/".$row['email']."'>unsubscribe</a>", $message); $newMessage .= '</body></html>'; $to = $row['email']; // Establish content headers $headers = "From: [email protected]"."\n"; $headers .= "Reply-To: [email protected]"."\n"; $headers .= "X-Mailer: PHP v.". phpversion()."\n"; $headers .= "MIME-Version: 1.0"."\n"; $headers .= "Content-Type: text/html; charset=iso-8859-1"."\n"; $headers .= "Content-Transfer-Encoding: 8bit;"; mail($to, $subject, $newMessage, $headers); // Send email to each individual user } This code works perfectly with a REALLY small database... I recently populated my test db with 200k+ users, and obviously this script fails, gets out of memory, and dies... I know this is a bad way to send so many emails, thats why I'd like to ask you for much more efficient ways to do this! Thank you very much!

• Why does Cacti keep waiting for dead poller processes?

  - by Oliver Salzburg

  sorry for the length I am currently setting up a new Debian (6.0.5) server. I put Cacti (0.8.7g) on it yesterday and have been battling with it ever since. Initial issue The initial issue I was observing, was that my graphs weren't updating. So I checked my cacti.log and found this concerning message: POLLER: Poller[0] Maximum runtime of 298 seconds exceeded. Exiting. That can't be good, right? So I went checking and started poller.php myself (via sudo -u www-data php poller.php --force). It will pump out a lot of message (which all look like what I would expect) and then hang for a minute. After that 1 minute, it will loop the following message: Waiting on 1 of 1 pollers. This goes on for 4 more minutes until the process is forcefully ended for running longer than 300s. So far so good I went on for a good hour trying to determine what poller might still be running, until I got to the conclusion that there simply is no running poller. Debugging I checked poller.php to see how that warning is issued and why. On line 368, Cacti will retrieve the number of finished processes from the database and use that value to calculate how many processes are still running. So, let's see that value! I added the following debug code into poller.php: print "Finished: " . $finished_processes . " - Started: " . $started_processes . "\n"; Result This will print the following within seconds of starting poller.php: Finished: 0 - Started: 1 Waiting on 1 of 1 pollers. Finished: 1 - Started: 1 So the values are being read and are valid. Until we get to the part where it keeps looping: Finished: - Started: 1 Waiting on 1 of 1 pollers. Suddenly, the value is gone. Why? Putting var_dump() in there confirms the issue: NULL Finished: - Started: 1 Waiting on 1 of 1 pollers. The return value is NULL. How can that be when querying SELECT COUNT()...? (SELECT COUNT() should always return one result row, shouldn't it?) More debugging So I went into lib\database.php and had a look at that db_fetch_cell(). A bit of testing confirmed, that the result set is actually empty. So I added my own database query code in there to see what that would do: $finished_processes = db_fetch_cell("SELECT count(*) FROM poller_time WHERE poller_id=0 AND end_time>'0000-00-00 00:00:00'"); print "Finished: " . $finished_processes . " - Started: " . $started_processes . "\n"; $mysqli = new mysqli("localhost","cacti","cacti","cacti"); $result = $mysqli->query("SELECT COUNT(*) FROM poller_time WHERE poller_id=0 AND end_time>'0000-00-00 00:00:00';"); $row = $result->fetch_assoc(); var_dump( $row ); This will output Finished: - Started: 1 array(1) { ["COUNT(*)"]=> string(1) "2" } Waiting on 1 of 1 pollers. So, the data is there and can be accessed without any problems, just not with the method Cacti is using? Double-check that! I enabled MySQL logging to make sure I'm not imagining things. Sure enough, when the error message is looped, the cacti.log reads as if it was querying like mad: 06/29/2012 08:44:00 PM - CMDPHP: Poller[0] DEVEL: SQL Cell: "SELECT count(*) FROM cacti.poller_time WHERE poller_id=0 AND end_time>'0000-00-00 00:00:00'" 06/29/2012 08:44:01 PM - CMDPHP: Poller[0] DEVEL: SQL Cell: "SELECT count(*) FROM cacti.poller_time WHERE poller_id=0 AND end_time>'0000-00-00 00:00:00'" 06/29/2012 08:44:02 PM - CMDPHP: Poller[0] DEVEL: SQL Cell: "SELECT count(*) FROM cacti.poller_time WHERE poller_id=0 AND end_time>'0000-00-00 00:00:00'" But none of these queries are logged my MySQL. Yet, when I add my own database query code, it shows up just fine. What the heck is going on here?

• Ubuntu 10.10 Ad-Hoc Setup (from Wireless Router, to Ubuntu Server/Desktop to Wireless Router)

  - by user60375

  Okay, so I know there are different approaches for this, but I will explain my story briefly before getting to the technical stuff. My fiancée and I are going through some financial issues (as I assume a lot of us are). We ended up having to move from our house and stay with some friends/family for 6 months, just to get ourselves caught up. (Medical bills, among other issues,etc). So this is where it gets fun. At our friends house, we are staying in the loft setup which is not near the cable modem and wireless router. I have a "hand-crafted" media center running XBMC, an Ubuntu 10.10 Server/Desktop (multi-purpose, very powerful and tons drive space), two working laptops, a between the two of us we have multiple wireless devices/phones. Now our friends Wireless router doesn't have any options for assigning IP addresses, but my router does. My current setup is: Friends Cable Modem -- Friend's Wireless Router -- Ubuntu 10.10 Server -- My Wireless Router (local-link from Friend's wireless (incoming) to sharing connection on ETH0 (outgoing)) -- to all devices. (Wireless Modem, Ubuntu Server that share's it's wireless incoming connection to the ethernet port my Wireless router share's with the rest of the devices). I setup my router to use default settings from my friend's router, using Google's DNS on my router (disabled DNS setup on Ubuntu Server), everything is assigned nicely and runs smooth. My Ubuntu server was given the address 10.42.43.1 (assuming standard from Network-Manager). (On the Ubuntu machine that shares to my wireless router; I have some server apps installed, but mainly just use Samba/NFS/Tangerine action. My problem/goal is that every device has no problem of accessing the internet from my router, the media-center has an assigned ip address, all services from all devices (ZeroConf, Avanhi, Bonjour, GIT, SSH, FTP, Apache2, etc) all work correctly except from my Ubuntu Server (which serves the wireless connection to ETH0 to another Wireless Router). The Ubuntu 10.10 Server/Desktop is not broadcasting anything (the Zeroconf Service Discovery 0.4 Gnome Applet shows the services from the Ubuntu server but no other computers can see them). I can access it from my Media-Center (Running Xbuntu 10.04) if I direct it to 10.42.43.1, no problem. But I cannot access Tangerine (Daapd) and the Samba shares do not show up on any computers for 10.42.43.1 (not in the WORKGROUP which Samba is setup simple and default but I can direct computers to that address and the shares will add except on a damn Windows 7 parition). Is this an issue with how I have my router setup and possible the gateway? An issue with Network-Manager? And issue with my Ubuntu Server/Desktop? I know there is a lot to that, but it's simpler than I probably have explained? Any help would be appreciated. If you need more details, I can provide them. If there is a better way of my attempting this home-network, please let me know. Thanks in advance for the help.
