  • JavaScript: function returning NAN

    - by Michael
    I'm working on a codecademy.com lesson with instructions to write the calculateTotal function below. When I click run, it's returning NaN. Anyone know what's wrong with the calculateTotal function as I wrote it that's making it return NaN. Note, I understand that NaN means not a number... // runner times var carlos = [9.6,10.6,11.2,10.3,11.5]; var liu = [10.6,11.2,9.4,12.3,10.1]; var timothy = [12.2,11.8,12.5,10.9,11.1]; // declare your function calculateTotal here var calculateTotal = function(raceTimes){ var totalTime; for(i = 0; i < raceTimes.length; i++){ totalTime += raceTimes[i]; return totalTime; } }; var liuTotal = calculateTotal(liu); console.log(liuTotal);

    I have a function that works on other pages but on this particular page its not working 100% the piece of code that is failing to work is: $query = "SELECT * FROM rank_punting JOIN rank_player ON rank_player.full_name=rank_punting.name WHERE active='1' AND class='$class' ORDER BY ABS(`rank_punting`.`rank_final`) ASC"; $rank = 0; $lastpct = 0; $db->setQuery($query); $result = $db->query(); if(mysql_num_rows($result) > 0) { while($row = mysql_fetch_array($result, MYSQL_ASSOC)) { if ($row['rank_final'] > $lastpct) { $rank++; $lastpct = $row['rank_final']; } $name = $row['name']; $s1= $row['s1']; $s2= $row['s2']; $s3= $row['s3']; $s4= $row['s4']; $s5= $row['s5']; $s6= $row['s6']; $s7= $row['s7']; $s8= $row['s8']; $s9= $row['s9']; $c1= $row['c1']; $c2= $row['c2']; $c3= $row['c3']; $c4= $row['c4']; $c5= $row['c5']; $c6= $row['c6']; $v1= $row['v1']; $v2= $row['v2']; $comp= $row['comp_rank_final']; $season= $row['season_rank_final']; $final=$row['rank_final']; $link = "website_url"; $link2 = "<a href=\"http://{$link}\" target='_blank'>{$name}<br>Profile Page</a>"; if ($link = ''){$link2 = "<a href='index.php?option=com_ranking&view=playerprofile&player={$name}' >{$name}<br>Profile Page</a>";} echo '<tr>'; echo " <th scope'row'>{$link2} {$lastpct} </th>"; echo "<td>"; echo 'DEBUG: '; echo $row['rank_final']; echo $lastpct;echo "{$rank}</td>"; echo "<td> Competition</td>"; echo "<td> {$comp}</td>"; echo "<td> {$c1}</td>"; echo "<td> {$c2}</td>"; echo "<td> {$c3}</td>"; echo "<td> {$c4}</td>"; echo "<td> {$c5}</td>"; echo "<td> {$c6}</td>"; echo "<td> {$c7}</td>"; echo "<td> {$c8}</td>"; echo "<td> {$v2}</td>"; echo "</tr>"; echo '<tr>'; echo "<th scope'row'> </th>"; echo "<td> </td>"; echo "<td> Game Film</td>"; echo "<td> {$season}</td>"; echo "<td> {$s1}</td>"; echo "<td> {$s2}</td>"; echo "<td> {$s3}</td>"; echo "<td> {$s4}</td>"; echo "<td> {$s5}</td>"; echo "<td> {$s7}</td>"; echo "<td> {$s8}</td>"; echo "<td> {$s6}</td>"; echo "<td> {$v1}</td>"; echo "</tr>"; } } //---------------- echo '</tbody> </table>'; }

  • How do I sync iPad Notes without Mail?

    - by Michael
    The default Notes app on the iPad is fine for my note taking needs. I see how it syncs through iTunes to Mail, but if one doesn't use Mail for e-mail management, is there any other way to sync and view the iPad notes on the desktop? (We use Eudora for mail management, and Apple's Mail is not great if all you want to do is view your notes with it.)

  • OSX Equivalent of Winsock LSP

    - by Michael
    On Windows, it's possible to program an LSP service on top of Winsock which provides the ability to do a lot of manipulation/etc. with networked applications. For instance, some anti virus applications register an LSP and analyse network traffic that way. Is there a friendly way to accomplish the same sort of thing on OSX?

  • Cannot access NSDictionary

    - by michael blaize
    I created a JSON using a PHP script. I am reading the JSON and can see that the data has been correctly read. However, when it comes to access the objects I get unrecognized selector sent to instance... Cannot seem to find why that is after too many hours !!!! Any help would be great ! My code looks like that: `NSDictionary *json = [[NSDictionary alloc] init]; json = [NSJSONSerialization JSONObjectWithData:receivedData options:kNilOptions error:&error]; NSLog(@"raw json = %@,%@",json,error); NSMutableArray *name = [[NSMutableArray alloc] init]; [name addObjectsFromArray: [json objectForKey:@"name"]];` The code crashes when reaching the last line above. The output like this: raw json = ( { category = vacancies; link = "http://blablabla.com"; name = "name 111111"; tagline = "tagline 111111"; }, { category = vacancies; link = "http://blobloblo.com"; name = "name 222222222"; tagline = "tagline 222222222"; } ),(null) 2012-06-23 21:46:57.539 Wind expert[4302:15203] -[__NSCFArray objectForKey:]: unrecognized selector sent to instance 0xdcfb970 HELP !!!

  • Creating an XmlNode/XmlElement in C# without an XmlDocument?

    - by Michael Stum
    I have a simple class that essentially just holds some values. I have overridden the ToString() method to return a nice string representation. Now, I want to create a ToXml() method, that will return something like this: <Song> <Artist>Bla</Artist> <Title>Foo</Title> </Song> Of course, I could just use a StringBuilder here, but I would like to return an XmlNode or XmlElement, to be used with XmlDocument.AppendChild. I do not seem to be able to create an XmlElement other than calling XmlDocument.CreateElement, so I wonder if I have just overlooked anything, or if I really either have to pass in either a XmlDocument or ref XmlElement to work with, or have the function return a String that contains the XML I want?

  • How to Detect Trusted Connection in Crystal Reports using VB.NET?

    - by Michael
    I have some Crystal Reports connecting to a Sql Server db that I would like to detect whether the connection is trusted or whether I need to supply the log on info (reports are not supplied by me so I can't control the connect method). If I just blindly supply login credentials, it won't connect if it is a trusted connection. The following does not work: oRpt = oCR.OpenReport("C:\MyReport.rpt") if oRpt.Database.Tables(1).ConnectionProperties.Item("Integrated Security") = True then 'trusted connection else 'supply login credentials end if It gives the following error: Operator '=' is not defined for type 'IConnectionProperty' and type 'Boolean'. I cannot find how create a construct in vb.net for IConnectionProperty. I can't find any documents from Crystal that explain it. I am using Crystal Reports XI - Developer

  • Are there any NOSQL-compatible CMS projects?

    - by Michael
    This question is partially related to an older question (Any CMS is Google App Engine compatible?) , but is slightly more general. It seems that in most CMS systems, the most fragile failure point is the database. Traditional database implementations scale poorly and will never be able to handle unforeseen spikes of traffic. Since Google App Engine was designed to help even small businesses overcome that problem, I had the same question that was asked earlier this year with less than satisfactory answers. But more generally, where are the CMS projects that support NOSQL databases? Looking over Wikipedia's list of CMS platforms, I see without much effort that only traditional RDBMS are supported by every single vendor on the list. I would have expected to see at least one or two projects handling CouchDB or similar engines. I understand the complexities of implementing a NOSQL solution to a problem that is typically solved using the relations cleanly expressed in any RDBMS, but there seems to be a rather wide market gap. Since databases are, today, easily outsourced to Google, Amazon, and others which use NOSQL models, I am amazed that there are not more projects actively pursuing this path. Am I simply not aware? Can someone please point me to projects that have real momentum that are developing on this path? I'm looking for two things: a CMS that has as its backbone a NOSQL database enabling easy database outsourcing (hosted MySQL clusters and similar solutions are not what I'm looking for) a project that is built to run on either a PaaS architecture like Google App Engine or an IaaS architecture like Amazon EC2 Any pointers in that direction would be most welcome.

  • Non class files with Java Web Start

    - by Michael Munsey
    How do you distribute other files needed by your application that aren't in a jar file? For example, the application at http://www.javabeginner.com/java-swing/java-swing-shuffle-game . The download contains Shuffle.jar, Shuffle.bat, Score.dat, and an images folder with 3 images in it. I can see possibly putting the images directly in Shuffle.jar, but you wouldn't want to put Score.dat in the jar file because it changes. Is there somewhere you could identify this type of file in the jnlp?

  • Cakephp beforeFind() - How do I add a JOIN condition AFTER the belongsTo association is added?

    - by michael
    I'm in Model-beforeFind($queryData), trying to add a JOIN condition to the queryData on a model which has belongsTo associations. Unfortunately, the new JOIN references a table in the belongsTo association, so it must appear AFTER the belongsTo in the query. Here is my Tagged-belongsTo association: app\plugins\tags\models\tagged.php (line 192) Array ( [Tag] => Array ( [className] => Tag [foreignKey] => tag_id [conditions] => [fields] => [order] => [counterCache] => ) [Group] => Array ( [className] => Group [foreignKey] => foreign_key [conditions] => Array ( [Tagged.model] => Group ) [fields] => [order] => [counterCache] => ) ) Here is the JOIN added in Tagged-beforeFind(), notice that the belongsTo joins have not yet been added: app\plugins\tags\models\tagged.php (line 194) Array ( [conditions] => Array ( [Tag.keyname] => europe ) [fields] => Array ( [0] => DISTINCT Group.* [1] => GroupPermission.* ) [joins] => Array ( [0] => Array ( [table] => permissions [alias] => GroupPermission [foreignKey] => [type] => INNER [conditions] => Array ( [GroupPermission.model] => Group [0] => GroupPermission.foreignId = Group.id [or] => Array ( ... ) ) ) ) [limit] => [offset] => [order] => Array ( [0] => ) [page] => 1 [group] => [callbacks] => 1 [by] => europe [model] => Group ) When I check the output, it fails with "1054: Unknown column 'Group.id' in 'on clause'" because the Permissions join appeared BEFORE the Groups join. SELECT DISTINCT `Group`.*, `GroupPermission`.* FROM `tagged` AS `Tagged` INNER JOIN permissions AS `GroupPermission` ON (`GroupPermission`.`model` = 'Group' AND `GroupPermission`.`foreignId` = `Group`.`id` AND (...)) LEFT JOIN `tags` AS `Tag` ON (`Tagged`.`tag_id` = `Tag`.`id`) LEFT JOIN `groups` AS `Group` ON (`Tagged`.`foreign_key` = `Group`.`id` AND `Tagged`.`model` = 'Group') WHERE `Tag`.`keyname` = 'europe' But this SQL (with Permissions joined moved to the end) works fine: SELECT DISTINCT `Group`.*, `GroupPermission`.* FROM `tagged` AS `Tagged` LEFT JOIN `tags` AS `Tag` ON (`Tagged`.`tag_id` = `Tag`.`id`) LEFT JOIN `groups` AS `Group` ON (`Tagged`.`foreign_key` = `Group`.`id` AND `Tagged`.`model` = 'Group') INNER JOIN permissions AS `GroupPermission` ON (`GroupPermission`.`model` = 'Group' AND `GroupPermission`.`foreignId` = `Group`.`id` AND (...)) WHERE `Tag`.`keyname` = 'europe' How do I add my join in beforeFind() after the belongsTo join?

  • Is it possible to tie nested generics?

    - by Michael Deardeuff
    Is it possible to tie nested generics/captures together? I often have the problem of having a Map lookup of class to genericized item of said class. In concrete terms I want something like this (no, T is not declared anywhere). private Map<Class<T>, ServiceLoader<T>> loaders = Maps.newHashMap(); In short, I want loaders.put/get to have semantics something like these: <T> ServiceLoader<T> get(Class<T> klass) {...} <T> void put(Class<T> klass, ServiceLoader<T> loader) {...} Is the following the best I can do? Do I have to live with the inevitable @SuppressWarnings("unchecked") somewhere down the line? private Map<Class<?>, ServiceLoader<?>> loaders = Maps.newHashMap();

  • Is there a way to wrap some local cache around a URLConnection

    - by Michael Neale
    I am using a URLConnection class - I want to be able to grab a stream to a given URL even if said URL is unavailable (ie cache the last known cope of the content on a URL, to some local file system dir) - now I have written this code a few times (never happy with it) and was wondering if there is something better out there that might be able to do this.

  • Should I use interface builder or not?

    - by Michael Waterfall
    I'd like to know more about the pros and cons of using interface builder when developing iPhone/iPad apps. I've written a fairly complex and customized app that's on the app store right now, but all of the interfaces are hand coded as they are fairly complex. I've customised the navigation and tab bars with backgrounds, table view cells are manually drawn for speed, and some views are complex and scalable with many subviews. I'm pondering whether or not to start using interface builder but I'm not sure to what extent I'll use it and whether it's worth it at all. Is it quicker? Can things still be easily customised? Any advice would be most welcome!
