  • $_GET loading content before head tag instead of in specified div.

    - by s32ialx
    NOT EDITING BELOW BUT THANKS TO SOME REALLY NICE PEOPLE I CAN'T POST AN IMAGE ANYMORE BECAUSE I HAD a 15 Rep but NOW ONLY A 5 becuase my question wasn't what they wanted help with they gave me a neg rep. The problem is that the content loads it displays UNDER the div i placed #CONTENT# inside so the styles are being ignored and it's posting #CONTENT# outside the divs at positions 0,0 any suggestions? Found out whats happening by using "View Source" seems that it's putting all of the #CONTENT#, content that's being loaded in front of the <head> tag. Like this <doctype...> <div class="home"> \ blah blah #CONTENT# bot being loaded in correct specified area </div> / <head> <script src=""></script> </head> <body> <div class="header"></div> <div class="contents"> #CONTENT# < where content SHOULD load </div> <div class="footer"></div> </body> so anyone got a fix? OK so a better description I'll add relevant screen-shots Whats happening is /* file.class.php */ <?php $file = new file(); class file{ var $path = "templates/clean"; var $ext = "tpl"; function loadfile($filename){ return file_get_contents($this->path . "/" . $filename . "." . $this->ext); } function setcontent($content,$newcontent,$vartoreplace='#CONTENT#'){ $val = str_replace($vartoreplace,$newcontent,$content); return $val; } function p($content) { $v = $content; $v = str_replace('#CONTENT#','',$v); print $v; } } if(!isset($_GET['page'])){ // if not, lets load our index page(you can change home.php to whatever you want: include("main.txt"); // else $_GET['page'] was set so lets do stuff: } else { // lets first check if the file exists: if(file_exists($_GET['page'].'.txt')){ // and lets include that then: include($_GET['page'].'.txt'); // sorry mate, could not find it: } else { echo 'Sorry, could not find <strong>' . $_GET['page'] .'.txt</strong>'; } } ?> is calling for a file_get_contents at the bottom which I use in /* index.php */ <!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" xml:lang="en" lang="en"> <?php include('classes/file.class.php'); // load the templates $header = $file->loadfile('header'); $body = $file->loadfile('body'); $footer = $file->loadfile('footer'); // fill body.tpl #CONTENT# slot with $content $body = $file->setcontent($body, $content); // cleanup and output the full page $file->p($header . $body . $footer); ?> and loads into /* body.tpl */ <div id="bodys"> <div id="bodt"></div> <div id="bodm"> <div id="contents"> #CONTENT# </div> </div> <div id="bodb"></div> </div> but the issue is as follows the $content loads properly img tags etc <h2> tags etc but CSS styling is TOTALY ignored for position width z-index etc. and as follows here's the screen-shot My Firefox Showing The Problem In Action REPOSTED DUE TO PEOPLE NOT HELPING AND JUST BEING ARROGANT AND GIVING NEGATIVE VOTES and not even saying a word.

  • Transaction issue in java with hibernate - latest entries not pulled from database

    - by Gearóid
    Hi, I'm having what seems to be a transactional issue in my application. I'm using Java 1.6 and Hibernate 3.2.5. My application runs a monthly process where it creates billing entries for a every user in the database based on their monthly activity. These billing entries are then used to create Monthly Bill object. The process is: Get users who have activity in the past month Create the relevant billing entries for each user Get the set of billing entries that we've just created Create a Monthly Bill based on these entries Everything works fine until Step 3 above. The Billing Entries are correctly created (I can see them in the database if I add a breakpoint after the Billing Entry creation method), but they are not pulled out of the database. As a result, an incorrect Monthly Bill is generated. If I run the code again (without clearing out the database), new Billing Entries are created and Step 3 pulls out the entries created in the first run (but not the second run). This, to me, is very confusing. My code looks like the following: for (User user : usersWithActivities) { createBillingEntriesForUser(user.getId()); userBillingEntries = getLastMonthsBillingEntriesForUser(user.getId()); createXMLBillForUser(user.getId(), userBillingEntries); } The methods called look like the following: @Transactional public void createBillingEntriesForUser(Long id) { UserManager userManager = ManagerFactory.getUserManager(); User user = userManager.getUser(id); List<AccountEvent> events = getLastMonthsAccountEventsForUser(id); BillingEntry entry = new BillingEntry(); if (null != events) { for (AccountEvent event : events) { if (event.getEventType().equals(EventType.ENABLE)) { Calendar cal = Calendar.getInstance(); Date eventDate = event.getTimestamp(); cal.setTime(eventDate); double startDate = cal.get(Calendar.DATE); double numOfDaysInMonth = cal.getActualMaximum(Calendar.DAY_OF_MONTH); double numberOfDaysInUse = numOfDaysInMonth - startDate; double fractionToCharge = numberOfDaysInUse/numOfDaysInMonth; BigDecimal amount = BigDecimal.valueOf(fractionToCharge * Prices.MONTHLY_COST); amount.scale(); entry.setAmount(amount); entry.setUser(user); entry.setTimestamp(eventDate); userManager.saveOrUpdate(entry); } } } } @Transactional public Collection<BillingEntry> getLastMonthsBillingEntriesForUser(Long id) { if (log.isDebugEnabled()) log.debug("Getting all the billing entries for last month for user with ID " + id); //String queryString = "select billingEntry from BillingEntry as billingEntry where billingEntry>=:firstOfLastMonth and billingEntry.timestamp<:firstOfCurrentMonth and billingEntry.user=:user"; String queryString = "select be from BillingEntry as be join be.user as user where user.id=:id and be.timestamp>=:firstOfLastMonth and be.timestamp<:firstOfCurrentMonth"; //This parameter will be the start of the last month ie. start of billing cycle SearchParameter firstOfLastMonth = new SearchParameter(); firstOfLastMonth.setTemporalType(TemporalType.DATE); //this parameter holds the start of the CURRENT month - ie. end of billing cycle SearchParameter firstOfCurrentMonth = new SearchParameter(); firstOfCurrentMonth.setTemporalType(TemporalType.DATE); Query query = super.entityManager.createQuery(queryString); query.setParameter("firstOfCurrentMonth", getFirstOfCurrentMonth()); query.setParameter("firstOfLastMonth", getFirstOfLastMonth()); query.setParameter("id", id); List<BillingEntry> entries = query.getResultList(); return entries; } public MonthlyBill createXMLBillForUser(Long id, Collection<BillingEntry> billingEntries) { BillingHistoryManager manager = ManagerFactory.getBillingHistoryManager(); UserManager userManager = ManagerFactory.getUserManager(); MonthlyBill mb = new MonthlyBill(); User user = userManager.getUser(id); mb.setUser(user); mb.setTimestamp(new Date()); Set<BillingEntry> entries = new HashSet<BillingEntry>(); entries.addAll(billingEntries); String xml = createXmlForMonthlyBill(user, entries); mb.setXmlBill(xml); mb.setBillingEntries(entries); MonthlyBill bill = (MonthlyBill) manager.saveOrUpdate(mb); return bill; } Help with this issue would be greatly appreciated as its been wracking my brain for weeks now! Thanks in advance, Gearoid.

  • a program similar to ls with some modifications

    - by Bond
    Hi, here is a simple puzzle I wanted to discuss. A C program to take directory name as command line argument and print last 3 directories and 3 files in all subdirectories without using api 'system' inside it. suppose directory bond0 contains bond1, di2, bond3, bond4, bond5 and my_file1, my_file2, my_file3, my_file4, my_file5, my_file6 and bond1 contains bond6 my_file7 my_file8 my_file9 my_file10 program should output - bond3, bond4, bond5, my_file4, my_file5, my_file6, bond6, my_file8, my_file9, my_file10 My code for the above problem is here #include<dirent.h> #include<unistd.h> #include<string.h> #include<sys/stat.h> #include<stdlib.h> #include<stdio.h> char *directs[20], *files[20]; int i = 0; int j = 0; int count = 0; void printdir(char *); int count_dirs(char *); int count_files(char *); int main() { char startdir[20]; printf("Scanning user directories\n"); scanf("%s", startdir); printdir(startdir); } void printdir(char *dir) { printf("printdir called %d directory is %s\n", ++count, dir); DIR *dp = opendir(dir); int nDirs, nFiles, nD, nF; nDirs = 0; nFiles = 0; nD = 0; nF = 0; if (dp) { struct dirent *entry = 0; struct stat statBuf; nDirs = count_dirs(dir); nFiles = count_files(dir); printf("The no of subdirectories in %s is %d \n", dir, nDirs); printf("The no of files in %s is %d \n", dir, nFiles); while ((entry = readdir(dp)) != 0) { if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) { continue; } char *filepath = malloc(strlen(dir) + strlen(entry->d_name) + 2); if (filepath) { sprintf(filepath, "%s/%s", dir, entry->d_name); if (lstat(filepath, &statBuf) != 0) { } if (S_ISDIR(statBuf.st_mode)) { nD++; if ((nDirs - nD) < 3) { printf("The directory is %s\n",entry->d_name); } } else { nF++; if ((nFiles - nF) < 3) { printf("The files are %s\n", entry->d_name); } //if } //else free(filepath); } //if(filepath) } //while while ((entry = readdir(dp)) != 0) { if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) { continue; } printf("In second while loop *entry=%s\n",entry->d_name); char *filepath = malloc(strlen(dir) + strlen(entry->d_name) + 2); if (filepath) { sprintf(filepath, "%s/%s", dir, entry->d_name); if (lstat(filepath, &statBuf) != 0) { } if (S_ISDIR(statBuf.st_mode)) { printdir(entry->d_name); } } //else free(filepath); } //2nd while closedir(dp); } else { fprintf(stderr, "Error, cannot open directory %s\n", dir); } } //printdir int count_dirs(char *dir) { DIR *dp = opendir(dir); int nD; nD = 0; if (dp) { struct dirent *entry = 0; struct stat statBuf; while ((entry = readdir(dp)) != 0) { if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) { continue; } char *filepath = malloc(strlen(dir) + strlen(entry->d_name) + 2); if (filepath) { sprintf(filepath, "%s/%s", dir, entry->d_name); if (lstat(filepath, &statBuf) != 0) { fprintf(stderr, "File Not found? %s\n", filepath); } if (S_ISDIR(statBuf.st_mode)) { nD++; } else { continue; } free(filepath); } } closedir(dp); } else { fprintf(stderr, "Error, cannot open directory %s\n", dir); } return nD; } int count_files(char *dir) { DIR *dp = opendir(dir); int nF; nF = 0; if (dp) { struct dirent *entry = 0; struct stat statBuf; while ((entry = readdir(dp)) != 0) { if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) { continue; } char *filepath = malloc(strlen(dir) + strlen(entry->d_name) + 2); if (filepath) { sprintf(filepath, "%s/%s", dir, entry->d_name); if (lstat(filepath, &statBuf) != 0) { fprintf(stderr, "File Not found? %s\n", filepath); } if (S_ISDIR(statBuf.st_mode)) { continue; } else { nF++; } free(filepath); } } closedir(dp); } else { fprintf(stderr, "Error, cannot open file %s\n", dir); } return nF; } The above code I wrote is a bit not functioning correctly can some one help me to understand the error which is coming.So that I improve it further.There seems to be some small glitch which is not clear to me right now.

  • Fetch a specific tag from Rally in order to compute a value in another field

    - by 4jas
    I'm extremely new to Rally development so my question may sound dumb (but couldn't find how to do it from rally's help or from previous posts here) :) I've started from the rally freeform grid example - my purpose is to implement a Business Value calculator: I fill the score field with a 5-digit figure where each number is a score in the 1-5 range. Then I compute a business value as the result of a calculation, where each number is weighted by a preset weight. I can sort my stories by Business Value to help me prioritize my backlog: that's the first step, and it works. Now what I want to do is to make my freeform grid editable: I am extracting each of my digits as a separate column, but those columns are display-only. How can I turn them into something editable? What I want to do of course is update back the score field based on the values input in each custom column. Here's an example: I have a record with score "15254", which means Business Value criteria 1 scores 1 out of 5, Business Value criteria 2 scores 5 out of 5, and so on... In the end my Business Value is computed as "1*1 + 5*2 + 2*3 + 5*4 + 4*5 = 57". So far this is the part that works. Now let's say I found that the third criteria should not score 2 but 3, I want to be able to edit the value in the corresponding column and have my score field updated to "15354", and my Business Value to display 60 instead of 57. Here is my current code, I'll be really grateful if you can help me with turning that grid into something editable :) <!--Include SDK--> <script type="text/javascript" src="https://rally1.rallydev.com/apps/2.0p2/sdk-debug.js"></script> <!--App code--> <script type="text/javascript"> Rally.onReady(function() { Ext.define('BVApp', { extend: 'Rally.app.App', componentCls: 'app', launch: function() { Ext.create('Rally.data.WsapiDataStore', { model: 'UserStory', autoLoad: true, listeners: { load: this._onDataLoaded, scope: this } }); }, _onDataLoaded: function(store, data) { var records = []; var li_score; var li_bv1, li_bv2, li_bv3, li_bv4, li_bv5, li_bvtotal; var weights = new Array(1, 2, 3, 4, 5); Ext.Array.each(data, function(record) { //Let's fetch score and compute the business values... li_score = record.get('Score'); if (li_score) { li_bv1 = li_score.toString().substring(0,1); li_bv2 = li_score.toString().substring(1,2); li_bv3 = li_score.toString().substring(2,3); li_bv4 = li_score.toString().substring(3,4); li_bv5 = li_score.toString().substring(4,5); li_bvtotal = li_bv1*weights[0] + li_bv2*weights[1] + li_bv3*weights[2] + li_bv4*weights[3] + li_bv5*weights[4]; } records.push({ FormattedID: record.get('FormattedID'), ref: record.get('_ref'), Name: record.get('Name'), Score: record.get('Score'), Bv1: li_bv1, Bv2: li_bv2, Bv3: li_bv3, Bv4: li_bv4, Bv5: li_bv5, BvTotal: li_bvtotal }); }); this.add({ xtype: 'rallygrid', store: Ext.create('Rally.data.custom.Store', { data: records, pageSize: 5 }), columnCfgs: [ { text: 'FormattedID', dataIndex: 'FormattedID' }, { text: 'ref', dataIndex: 'ref' }, { text: 'Name', dataIndex: 'Name', flex: 1 }, { text: 'Score', dataIndex: 'Score' }, { text: 'BusVal 1', dataIndex: 'Bv1' }, { text: 'BusVal 2', dataIndex: 'Bv2' }, { text: 'BusVal 3', dataIndex: 'Bv3' }, { text: 'BusVal 4', dataIndex: 'Bv4' }, { text: 'BusVal 5', dataIndex: 'Bv5' }, { text: 'BusVal Total', dataIndex: 'BvTotal' } ] }); } }); Rally.launchApp('BVApp', { name: 'Business Values App' }); var exampleHtml = '<div id="example-intro"><h1>Business Values App</h1>' + '<div>Own sample app for Business Values</div>' + '</div>'; // Default app viewport uses layout: 'fit', // so we need to insert a container into the viewport var viewport = Ext.ComponentQuery.query('viewport')[0]; var appComponent = viewport.items.getAt(0); var viewportContainerItems = [{ html: exampleHtml, border: 0 }]; //hide advanced cardboard live previews in examples for now viewportContainerItems.push({ xtype: 'container', items: [appComponent] }); viewport.remove(appComponent, false); viewport.add({ xtype: 'container', layout: 'vbox', items: viewportContainerItems }); }); </script> <!--App styles--> <style type="text/css"> .app { /* Add app styles here */ } </style>

  • Work time in fullcalendar [Solution]

    - by Zozo
    Full calendar have no included options to work-time feature (selecting first and last rows in agenda view for any day - where in example company is not working). I managed something like that: viewDisplay: function(view){ $.ajax({ url: 'index.php?r=calendar/Default/worktime', dataType: 'json', success: function(data){ if(view.name=='agendaWeek') selectWorkTime(data, 30, 0, 24, false); else if(view.name=='agendaDay') selectDayWorkTime(data, 30, 0, 24, view, false); } }); } Where index.php?r=calendar/Default/worktime is php file returning json. It looks like that: $arr = array( 'mon' => array('8:00', '17:00'), 'tue' => array('9:00', '15:00'), 'wed' => array('9:30', '19:00'), 'thu' => array('6:00', '14:00'), 'fri' => array('0:00', '24:00'), 'sat' => array('9:00', '14:00'), 'sun' => array() ); foreach ($arr as &$day){ foreach($day as &$hour){ $tmp = explode(':', $hour); $hour = $tmp[0] * 3600 + $tmp[1] * 60; } } print json_encode($arr); and at the end, some functions using for counting and selecting work-time: function selectDayWorkTime(timeArray, slotMinutes, minTime, maxTime, viewObject, showAtHolidays){ var dayname; $('.fc-content').find('.fc-view-agendaWeek').find('.fc-agenda-body') .children('.fc-work-time').remove(); $('.fc-content').find('.fc-view-agendaDay') .find('.fc-work-time-day').removeClass('fc-work-time-day'); switch(viewObject.start.getDay()){ case 1: dayname='mon'; break; case 2: dayname='tue'; break; case 3: dayname='wed'; break; case 4: dayname='thu'; break; case 5: dayname='fri'; break; case 6: dayname='sat'; break; case 0: dayname='sun'; break; } for(var day in timeArray){ if(day == dayname){ if($('.fc-content').find('.fc-view-agendaDay').find('.fc-'+day).attr('class').search('fc-holiday') == -1 || showAtHolidays){ var startBefore = 0; var endBefore = timeArray[day][0] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var startAfter = timeArray[day][1] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var endAfter = (maxTime - minTime) * 60 / slotMinutes - 1; for(startBefore; startBefore < endBefore; startBefore++){ $('.fc-view-agendaDay').find('.fc-slot'+startBefore).find('div').addClass('fc-work-time-day'); } for(startAfter; startAfter <= endAfter; startAfter++){ $('.fc-view-agendaDay').find('.fc-slot'+startAfter).find('div').addClass('fc-work-time-day'); } } } } } function selectWorkTime(timeArray, slotMinutes, minTime, maxTime, showAtHolidays){ for(var day in timeArray){ var startBefore = 0; var endBefore = timeArray[day][0] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var startAfter = timeArray[day][1] / (60 * slotMinutes) - (minTime * 60) / slotMinutes; var endAfter = (maxTime - minTime) * 60 / slotMinutes - 1; if(startBefore > endBefore) endBefore = startBefore; if(startAfter > endAfter) startAfter = endAfter; try{ selectCell(startBefore, endBefore, 'fc-'+day, 'fc-work-time', false, showAtHolidays); selectCell(startAfter, endAfter, 'fc-'+day, 'fc-work-time', true, showAtHolidays); } catch(e){ continue; } } } function selectCell(startRowNo, endRowNo, collClass, cellClass, closeGap, showAtHolidays){ $('.fc-content').find('.fc-view-agendaWeek').find('.fc-agenda-body') .children('.'+cellClass+''+startRowNo+''+collClass).remove(); $('.fc-content').find('.fc-view-agendaDay') .find('.fc-work-time-day').removeClass('fc-work-time-day'); if($('.fc-content').find('.fc-view-agendaWeek').find('.'+collClass).attr('class').search('fc-holiday') == -1 || showAtHolidays){ var width = $('.fc-content').find('.fc-view-agendaWeek') .find('.'+collClass+':last').width(); var height = 0; if(closeGap && (startRowNo != endRowNo)){ height = $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).height(); } $('.fc-view-agendaWeek').find('.fc-agenda-body').prepend('<div class="'+cellClass+' ' + ''+cellClass+''+startRowNo+''+collClass+'"></div>'); $('.'+cellClass).width(width - 2); height += $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ endRowNo).position().top - $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).position().top; $('.'+cellClass+''+startRowNo+''+collClass).height(height); $('.'+cellClass+''+startRowNo+''+collClass) .css('margin-top', $('.fc-content').find('.fc-view-agendaWeek') .find('.fc-slot'+ startRowNo).position().top); $('.'+cellClass+''+startRowNo+''+collClass) .css('margin-left', $('.fc-content').find('.fc-view-agendaWeek') .find('.'+collClass+':last').offset().left - width / 2); } } Don't forget about CSS: .fc-work-time-day{ background-color: yellow; opacity: 0.3; filter: alpha(opacity=30); /* for IE */ } .fc-work-time{ position: absolute; background-color: yellow; z-index:10; margin: 0; padding: 0; text-align: left; z-index: 0; opacity: 0.3; filter: alpha(opacity=30); /* for IE */ } So, I've got some questions about - is the other way to make the same, but no using absolute div's in agendaWeek? And... How can I get in viewDisplay function actual slotMinutes, minTime and maxTime

  • New hire expectations... (Am I being unreasonable?)

    - by user295841
    I work for a very small custom software shop. We currently consist me and my boss. My boss is an old FoxPro DOS developer and OOP makes him uncomfortable. He is planning on taking a back seat in the next few years to hopefully enjoy a “partial retirement”. I will be taking over the day to day operations and we are now desperately looking for more help. We tried Monster.com, Dice.com, and others a few years ago when we started our search. We had no success. We have tried outsourcing overseas (total disaster), hiring kids right out of college (mostly a disaster but that’s where I came from), interns (good for them, not so good for us) and hiring laid off “experienced” developers (there was a reason they were laid off). I have heard hiring practices discussed on podcasts, blogs, etc... and have tried a few. The “Fizz Buzz” test was a good one. One kid looked physically ill before he finally gave up. I think my problem is that I have grown so much as a developer since I started here that I now have a high standard. I hear/read very intelligent people podcasts and blogs and I know that there are lots of people out there that can do the job. I don’t want to settle for less than a “good” developer. Perhaps my expectations are unreasonable. I expect any good developer (entry level or experienced) to be billable (at least paying their own wage) in under one month. I expect any good developer to be able to be productive (at least dangerous) in any language or technology with only a few days of research/training. I expect any good developer to be able to take a project from initial customer request to completion with little or no help from others. Am I being unreasonable? What constitutes a valuable developer? What should be expected of an entry level developer? What should be expected of an experienced developer? I realize that everyone is different but there has to be some sort of expectations standard, right? I have been giving the test project below to potential canidates to weed them out. Good idea? Too much? Too little? Please let me know what you think. Thanks.

  • Creating a new plugin for mpld3

    - by sjp14051
    Toward learning how to create a new mpld3 plugin, I took an existing example, LinkedDataPlugin (http://mpld3.github.io/examples/heart_path.html), and modified it slightly by deleting references to lines object. That is, I created the following: class DragPlugin(plugins.PluginBase): JAVASCRIPT = r""" mpld3.register_plugin("drag", DragPlugin); DragPlugin.prototype = Object.create(mpld3.Plugin.prototype); DragPlugin.prototype.constructor = DragPlugin; DragPlugin.prototype.requiredProps = ["idpts", "idpatch"]; DragPlugin.prototype.defaultProps = {} function DragPlugin(fig, props){ mpld3.Plugin.call(this, fig, props); }; DragPlugin.prototype.draw = function(){ var patchobj = mpld3.get_element(this.props.idpatch, this.fig); var ptsobj = mpld3.get_element(this.props.idpts, this.fig); var drag = d3.behavior.drag() .origin(function(d) { return {x:ptsobj.ax.x(d[0]), y:ptsobj.ax.y(d[1])}; }) .on("dragstart", dragstarted) .on("drag", dragged) .on("dragend", dragended); patchobj.path.attr("d", patchobj.datafunc(ptsobj.offsets, patchobj.pathcodes)); patchobj.data = ptsobj.offsets; ptsobj.elements() .data(ptsobj.offsets) .style("cursor", "default") .call(drag); function dragstarted(d) { d3.event.sourceEvent.stopPropagation(); d3.select(this).classed("dragging", true); } function dragged(d, i) { d[0] = ptsobj.ax.x.invert(d3.event.x); d[1] = ptsobj.ax.y.invert(d3.event.y); d3.select(this) .attr("transform", "translate(" + [d3.event.x,d3.event.y] + ")"); patchobj.path.attr("d", patchobj.datafunc(ptsobj.offsets, patchobj.pathcodes)); } function dragended(d, i) { d3.select(this).classed("dragging", false); } } mpld3.register_plugin("drag", DragPlugin); """ def __init__(self, points, patch): print "Points ID : ", utils.get_id(points) self.dict_ = {"type": "drag", "idpts": utils.get_id(points), "idpatch": utils.get_id(patch)} However, when I try to link the plugin to a figure, as in plugins.connect(fig, DragPlugin(points[0], patch)) I get an error, 'module' is not callable, pointing to this line. What does this mean and why doesn't it work? Thanks. I'm adding additional code to show that linking more than one Plugin might be problematic. But this may be entirely due to some silly mistake on my part, or there is a way around it. The following code based on LinkedViewPlugin generates three panels, in which the top and the bottom panel are supposed to be identical. Mouseover in the middle panel was expected to control the display in the top and bottom panels, but updates occur in the bottom panel only. It would be nice to be able to figure out how to reflect the changes in multiple panels.

  • c++ and c# speed compared

    - by Mack
    I was worried about C#'s speed when it deals with heavy calculations, when you need to use raw CPU power. I always thought that C++ is much faster than C# when it comes to calculations. So I did some quick tests. The first test computes prime numbers < an integer n, the second test computes some pandigital numbers. The idea for second test comes from here: Pandigital Numbers C# prime computation: using System; using System.Diagnostics; class Program { static int primes(int n) { uint i, j; int countprimes = 0; for (i = 1; i <= n; i++) { bool isprime = true; for (j = 2; j <= Math.Sqrt(i); j++) if ((i % j) == 0) { isprime = false; break; } if (isprime) countprimes++; } return countprimes; } static void Main(string[] args) { int n = int.Parse(Console.ReadLine()); Stopwatch sw = new Stopwatch(); sw.Start(); int res = primes(n); sw.Stop(); Console.WriteLine("I found {0} prime numbers between 0 and {1} in {2} msecs.", res, n, sw.ElapsedMilliseconds); Console.ReadKey(); } } C++ variant: #include <iostream> #include <ctime> int primes(unsigned long n) { unsigned long i, j; int countprimes = 0; for(i = 1; i <= n; i++) { int isprime = 1; for(j = 2; j < (i^(1/2)); j++) if(!(i%j)) { isprime = 0; break; } countprimes+= isprime; } return countprimes; } int main() { int n, res; cin>>n; unsigned int start = clock(); res = primes(n); int tprime = clock() - start; cout<<"\nI found "<<res<<" prime numbers between 1 and "<<n<<" in "<<tprime<<" msecs."; return 0; } When I ran the test trying to find primes < than 100,000, C# variant finished in 0.409 seconds and C++ variant in 5.553 seconds. When I ran them for 1,000,000 C# finished in 6.039 seconds and C++ in about 337 seconds. Pandigital test in C#: using System; using System.Diagnostics; class Program { static bool IsPandigital(int n) { int digits = 0; int count = 0; int tmp; for (; n > 0; n /= 10, ++count) { if ((tmp = digits) == (digits |= 1 << (n - ((n / 10) * 10) - 1))) return false; } return digits == (1 << count) - 1; } static void Main() { int pans = 0; Stopwatch sw = new Stopwatch(); sw.Start(); for (int i = 1; i <= 123456789; i++) { if (IsPandigital(i)) { pans++; } } sw.Stop(); Console.WriteLine("{0}pcs, {1}ms", pans, sw.ElapsedMilliseconds); Console.ReadKey(); } } Pandigital test in C++: #include <iostream> #include <ctime> using namespace std; int IsPandigital(int n) { int digits = 0; int count = 0; int tmp; for (; n > 0; n /= 10, ++count) { if ((tmp = digits) == (digits |= 1 << (n - ((n / 10) * 10) - 1))) return 0; } return digits == (1 << count) - 1; } int main() { int pans = 0; unsigned int start = clock(); for (int i = 1; i <= 123456789; i++) { if (IsPandigital(i)) { pans++; } } int ptime = clock() - start; cout<<"\nPans:"<<pans<<" time:"<<ptime; return 0; } C# variant runs in 29.906 seconds and C++ in about 36.298 seconds. I didn't touch any compiler switches and bot C# and C++ programs were compiled with debug options. Before I attempted to run the test I was worried that C# will lag well behind C++, but now it seems that there is a pretty big speed difference in C# favor. Can anybody explain this? C# is jitted and C++ is compiled native so it's normal that a C++ will be faster than a C# variant. Thanks for the answers!

  • Optimizing python code performance when importing zipped csv to a mongo collection

    - by mark
    I need to import a zipped csv into a mongo collection, but there is a catch - every record contains a timestamp in Pacific Time, which must be converted to the local time corresponding to the (longitude,latitude) pair found in the same record. The code looks like so: def read_csv_zip(path, timezones): with ZipFile(path) as z, z.open(z.namelist()[0]) as input: csv_rows = csv.reader(input) header = csv_rows.next() check,converters = get_aux_stuff(header) for csv_row in csv_rows: if check(csv_row): row = { converter[0]:converter[1](value) for converter, value in zip(converters, csv_row) if allow_field(converter) } ts = row['ts'] lng, lat = row['loc'] found_tz_entry = timezones.find_one(SON({'loc': {'$within': {'$box': [[lng-tz_lookup_radius, lat-tz_lookup_radius],[lng+tz_lookup_radius, lat+tz_lookup_radius]]}}})) if found_tz_entry: tz_name = found_tz_entry['tz'] local_ts = ts.astimezone(timezone(tz_name)).replace(tzinfo=None) row['tz'] = tz_name else: local_ts = (ts.astimezone(utc) + timedelta(hours = int(lng/15))).replace(tzinfo = None) row['local_ts'] = local_ts yield row def insert_documents(collection, source, batch_size): while True: items = list(itertools.islice(source, batch_size)) if len(items) == 0: break; try: collection.insert(items) except: for item in items: try: collection.insert(item) except Exception as exc: print("Failed to insert record {0} - {1}".format(item['_id'], exc)) def main(zip_path): with Connection() as connection: data = connection.mydb.data timezones = connection.timezones.data insert_documents(data, read_csv_zip(zip_path, timezones), 1000) The code proceeds as follows: Every record read from the csv is checked and converted to a dictionary, where some fields may be skipped, some titles be renamed (from those appearing in the csv header), some values may be converted (to datetime, to integers, to floats. etc ...) For each record read from the csv, a lookup is made into the timezones collection to map the record location to the respective time zone. If the mapping is successful - that timezone is used to convert the record timestamp (pacific time) to the respective local timestamp. If no mapping is found - a rough approximation is calculated. The timezones collection is appropriately indexed, of course - calling explain() confirms it. The process is slow. Naturally, having to query the timezones collection for every record kills the performance. I am looking for advises on how to improve it. Thanks. EDIT The timezones collection contains 8176040 records, each containing four values: > db.data.findOne() { "_id" : 3038814, "loc" : [ 1.48333, 42.5 ], "tz" : "Europe/Andorra" } EDIT2 OK, I have compiled a release build of http://toblerity.github.com/rtree/ and configured the rtree package. Then I have created an rtree dat/idx pair of files corresponding to my timezones collection. So, instead of calling collection.find_one I call index.intersection. Surprisingly, not only there is no improvement, but it works even more slowly now! May be rtree could be fine tuned to load the entire dat/idx pair into RAM (704M), but I do not know how to do it. Until then, it is not an alternative. In general, I think the solution should involve parallelization of the task.

  • Button in Update Panel doing full postback?

    - by sah302
    No this isn't a copy of this question: http://stackoverflow.com/questions/654423/button-in-update-panel-is-doing-a-full-postback I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel. Code Behind: Public accomplishmentTypeDao As New AccomplishmentTypeDao() Public accomplishmentDao As New AccomplishmentDao() Public userDao As New UserDao() Public facultyDictionary As New Dictionary(Of Guid, String) Public facultyList As New List(Of User) Public associatedFaculty As New List(Of User) Public facultyId As New Guid Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Page.Title = "Add a New Faculty Accomplishment" ddlAccomplishmentType.DataSource = accomplishmentTypeDao.getEntireTable() ddlAccomplishmentType.DataTextField = "Name" ddlAccomplishmentType.DataValueField = "Id" ddlAccomplishmentType.DataBind() facultyList = userDao.getListOfUsersByUserGroupName("Faculty") For Each faculty As User In facultyList facultyDictionary.Add(faculty.Id, faculty.LastName & ", " & faculty.FirstName) Next If Not Page.IsPostBack Then ddlFacultyList.DataSource = facultyDictionary ddlFacultyList.DataTextField = "Value" ddlFacultyList.DataValueField = "Key" ddlFacultyList.DataBind() End If gvAssociatedUsers.DataSource = associatedFaculty gvAssociatedUsers.DataBind() End Sub Protected Sub deleteUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) facultyId = New Guid(e.CommandArgument.ToString()) associatedFaculty.Remove(associatedFaculty.Find(Function(user) user.Id = facultyId)) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub btnAddUser_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddUser.Click facultyId = New Guid(ddlFacultyList.SelectedValue) associatedFaculty.Add(facultyList.Find(Function(user) user.Id = facultyId)) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Markup: <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="upAssociatedFaculty" runat="server" UpdateMode="Conditional"> <ContentTemplate> <p><b>Created By:</b> <asp:Label ID="lblCreatedBy" runat="server"></asp:Label></p> <p><b>Accomplishment Type: </b><asp:DropDownList ID="ddlAccomplishmentType" runat="server"></asp:DropDownList></p> <p><b>Accomplishment Applies To: </b><asp:DropDownList ID="ddlFacultyList" runat="server"></asp:DropDownList> &nbsp;<asp:Button ID="btnAddUser" runat="server" Text="Add Faculty" /></p> <p> <asp:GridView ID="gvAssociatedUsers" runat="server" AutoGenerateColumns="false" GridLines="None" ShowHeader="false"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" Visible="False" /> <asp:TemplateField ShowHeader="False"> <ItemTemplate> <span style="margin-left: 15px;"> <p><%#Eval("LastName")%>, <%#Eval("FirstName")%> <asp:Button ID="btnUnassignUser" runat="server" CausesValidation="false" CommandArgument='<%# Eval("Id") %>' CommandName="Delete" OnCommand="deleteUser" Text='Remove' /></p> </span> </ItemTemplate> </asp:TemplateField> </Columns> <EmptyDataTemplate> <em>There are currently no faculty associated with this accomplishment.</em> </EmptyDataTemplate> </asp:GridView> </p> </ContentTemplate> </asp:UpdatePanel> Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again. I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked. I know this is something simple, but all the combinations I've tried won't get it to work. How can I make this thing work?

  • textbox disappears in paging - php

    - by fusion
    i'm calling the search.php page via ajax to search.html. the problem is, since i've implemented paging, the textbox with the search keyword from search.html 'disappears' when the user clicks the 'Next' button [because the page goes to search.php which has no textbox element] i'd like the textbox with the search keyword to be there, when the user goes through the records via paging. how'd i achieve this? search.html: <body> <form name="myform" class="wrapper"> <input type="text" name="q" onkeyup="showPage();" class="txt_search"/> <input type="button" name="button" onclick="showPage();" class="button"/> <p> <div id="txtHint"></div> <div id="page"></div> </form> </body> search.php [the relevant part]: $self = $_SERVER['PHP_SELF']; $limit = 5; //Number of results per page $numpages=ceil($totalrows/$limit); $query = $query." ORDER BY idQuotes LIMIT " . ($page-1)*$limit . ",$limit"; $result = mysql_query($query, $conn) or die('Error:' .mysql_error()); ?> <div class="caption">Search Results</div> <div class="center_div"> <table> <?php while ($row= mysql_fetch_array($result, MYSQL_ASSOC)) { $cQuote = highlightWords(htmlspecialchars($row['cQuotes']), $search_result); ?> <tr> <td style="text-align:right; font-size:15px;"><?php h($row['cArabic']); ?></td> <td style="font-size:16px;"><?php echo $cQuote; ?></td> <td style="font-size:12px;"><?php h($row['vAuthor']); ?></td> <td style="font-size:12px; font-style:italic; text-align:right;"><?php h($row['vReference']); ?></td> </tr> <?php } ?> </table> </div> <?php //Create and print the Navigation bar $nav=""; if($page > 1) { $nav .= "<a href=\"$self?page=" .

  • pagination in css/php

    - by fusion
    two questions: --1-- it displays all the number of pages. but i'd like it to display as: << Prev . . 3 4 [5] 6 7 . . Next --2-- when i hover on the current page no, it should change color or increase the font-size, but when i modify the css of a:hover, all the page nos change color or size instead of the one which i'm pointing to. also, when modifying a:active, nothing happens. this is my paging code in php: $self = $_SERVER['PHP_SELF']; $limit = 2; //Number of results per page $numpages=ceil($totalrows/$limit); $query = $query."

  • jQuery programming style?

    - by Sam Dufel
    I was recently asked to fix something on a site which I haven't worked on before. I haven't really worked with jQuery that much, but I figured I'd take a look and see if I could fix it. I've managed to mostly clear up the problem, but I'm still horrified at the way they chose to build this site. On document load, they replace the click() method of every anchor tag and form element with the same massive function. When clicked, that function then checks if the tag has one of a few different attributes (non-standard attributes, even), and does a variety of different tasks depending on what attributes exist and what their values are. Some hyperlinks have an attribute on them called 'ajaxrel', which makes the click() function look for another (hidden) hyperlink with an ID specified by the ajaxrel attribute, and then calls the click() function for that other hyperlink (which was also modified by this same click() function). On the server side, all the php files are quite long and have absolutely no indentation. This whole site has been a nightmare to debug. Is this standard jQuery practice? This navigation scheme seems terrible. Does anyone else actually use jQuery this way? I'd like to start incorporating it into my projects, but looking at this site is giving me a serious headache. Here's the click() function for hyperlinks: function ajaxBoxA(theElement, urltosend, ajaxbox, dialogbox) { if ($(theElement).attr("href") != undefined) var urltosend = $(theElement).attr("href"); if ($(theElement).attr('toajaxbox') != undefined) var ajaxbox = $(theElement).attr('toajaxbox'); // check to see if dialog box is called for. if ($(theElement).attr('dialogbox') != undefined) var dialogbox = $(theElement).attr('dialogbox'); var dodialog = 0; if (dialogbox != undefined) { // if dialogbox doesn't exist, then flag to create dialog box. var isDiaOpen = $('[ajaxbox="' + ajaxbox + '"]').parent().parent().is(".ui-dialog-container"); dodialog = 1; if (isDiaOpen) { dodialog = 0; } dialogbox = parseUri(dialogbox); dialogoptions = { close: function () { // $("[id^=hierarchy]",this).NestedSortableDestroy(); $(this).dialog('destroy').remove() } }; for ( var keyVar in dialogbox['queryKey'] ) eval( "dialogoptions." + keyVar + " = dialogbox['queryKey'][keyVar]"); }; $("body").append("<div id='TB_load'><img src='"+imgLoader.src+"' /></div>"); $('#TB_load').show(); if (urltosend.search(/\?/) > 0) { urltosend = urltosend + "&-ajax=1"; } else { urltosend = urltosend + "?-ajax=1"; } if ($('[ajaxbox="' + ajaxbox + '"]').length) { $('[ajaxbox="' + ajaxbox + '"]').each( function () { $(this).empty(); }); }; $.ajax({ type: "GET", url: urltosend, data: "", async: false, dataType: "html", success: function (html) { var re = /^<toajaxbox>(.*?)<\/toajaxbox>+(.*)/; if (re.test(html)) { var match = re.exec(html); ajaxbox = match[1]; html = Right(html, String(html).length - String(match[1]).length); } var re = /^<header>(.*?)<\/header>+(.*)/; if (re.test(html)) { var match = re.exec(html); window.location = match[1]; return false; } if (html.length > 0) { var newHtml = $(html); if ($('[ajaxbox="' + ajaxbox + '"]').length) { $('[ajaxbox="' + ajaxbox + '"]').each( function () { $(this).replaceWith(newHtml).ready( function () { ajaxBoxInit(newHtml) if (window.ajaxboxsuccess) ajaxboxsuccess(newHtml); }); }); if ($('[ajaxdialog="' + ajaxbox + '"]').length = 0) { if (dodialog) $(newHtml).wrap("<div class='flora ui-dialog-content' ajaxdialog='" + ajaxbox + "' style='overflow:auto;'></div>").parent().dialog(dialogoptions); } } else { $("body").append(newHtml).ready( function () { ajaxBoxInit(newHtml); if (window.ajaxboxsuccess) ajaxboxsuccess(newHtml); }); if (dodialog) $(newHtml).wrap("<div class='flora ui-dialog-content' ajaxdialog='" + ajaxbox + "' style='overflow:auto;'></div>").parent().dialog(dialogoptions); } } var rel = $(theElement).attr('ajaxtriggerrel'); if (rel != undefined) $('a[ajaxrel="' + rel + '"]').click(); tb_remove(); return false; }, complete: function () { $("#TB_load").remove(); } }); return false; }

  • listbox isSelected databinding in DataTemplate

    - by Kinmarui
    I try to simply databind IsSelected property with IsSelected field in my class. But after I change the value in code its doesn't change the property, neither does clicking on ListBoxItem change the field value. XAML: <FlipView ItemsSource="{Binding Source={StaticResource itemsViewSource}}" ... > <FlipView.ItemTemplate> <DataTemplate> <UserControl Loaded="StartLayoutUpdates" Unloaded="StopLayoutUpdates"> <!-- other controls --> <ListBox Grid.Row="1" Grid.ColumnSpan="3" SelectionMode="Multiple" VerticalAlignment="Center" ItemsSource="{Binding Answers}"> <ListBox.Resources> <local:LogicToText x:Key="logToText" /> </ListBox.Resources> <!-- bind IsSelected only in one way from code to content --> <ItemsControl.ItemTemplate> <DataTemplate> <ListBoxItem IsSelected="{Binding IsSelected, Mode=TwoWay, Converter={StaticResource logToText}}" Content="{Binding IsSelected, Mode=TwoWay, Converter={StaticResource logToText}}"> </ListBoxItem> </DataTemplate> </ItemsControl.ItemTemplate> <!-- not working at all <ListBox.Resources> <Style TargetType="ListBoxItem"> <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}"/> <Setter Property="Content" Value="{Binding IsSelected, Mode=TwoWay}"/> </Style> </ListBox.Resources>--> </ListBox> </UserControl> </DataTemplate> </FlipView.ItemTemplate> </FlipView> Code: Answers private ObservableCollection<PrawoJazdyDataAnswer> _answers = new ObservableCollection<PrawoJazdyDataAnswer>(); public ObservableCollection<PrawoJazdyDataAnswer> Answers { get { return this._answers; } } Single item(Answer) public class PrawoJazdyDataAnswer : NPCHelper// PrawoJazdy.Common.BindableBase { public PrawoJazdyDataAnswer(String ans, bool ansb) { this._ans = ans; this._isSelected = ansb; } public override string ToString() { return _isSelected.ToString(); } //Only For debug purposes normally return _ans; private string _ans; public string Ans { get { return this._ans; } //set { this.SetProperty(ref this._ans, value); } } private bool _isSelected; public bool IsSelected { get { return this._isSelected; } set { _isSelected = value; FirePropertyChanged("IsSelected"); //this.SetProperty(ref this._isSelected, value); } } } FirePropertyChanged public class NPCHelper : INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public void FirePropertyChanged(string prop) { if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(prop)); } } Converter(which sometimes seems to be needed and others not..., I tried ~10 approaches from different tutorials/examples) public class LogicToText : IValueConverter { /// <summary> /// /// </summary> public object Convert(object value, Type targetType, object parameter, string language) { //if (value == null || (bool)value == false) // return "False"; return value.ToString(); } /// <summary> /// /// </summary> public object ConvertBack(object value, Type targetType, object parameter, string language) { return value.ToString().Contains("True") ? true : false; } Thanks in advance, and sorry for my English(still learning). @edit Thanks for quick reply. For test purposes i created a button and text block: It's in other controls part (above list box, but in FlipView) <Button Click="spr" >Sprawdz</Button> <TextBlock Text="{Binding Answers[0].IsSelected, Mode=TwoWay}" > </TextBlock> Click method private void spr(object sender, RoutedEventArgs e) { var ans = ((PrawoJazdyDataQuestion)this.flipView.SelectedItem).Answers; foreach (var item in ans) item.IsSelected = item.IsSelected ? false : true; } As I wrote when i'm changing data from code side its change text, but not appearance of ListBoxItem, and if i just select it on ListBox its doesn't change the date i textblock neither in ListBox itself.
