  • Kohana 3 - How do I make the Default Route pass arguments to the Controller's Action?

    - by John Himmelman
    My controller action requires a parameter, but I can't get KO3's router to pass this parameter in the Default route. This sort of thing works with other routes. Here is an example to clarify... In bootstrap.php... Route::set('default', '(<controller>(/<action>(/<the_required_param>)))') ->defaults(array( 'controller' => 'DefaultController', 'action' => 'index', 'the_required_param' => 'some_default_value', )); In controller file... class DefaultController extends Controller { public function index($the_required_param) { echo 'value: ' . $the_required_param; } }

  • UITableViewController executes delate functions before network request finishes

    - by user1543132
    I'm having trouble trying to populate a UITableView with the results of a network request. It seems that my code is alright as it works perfectly when my network is speedy, however, when it's not, the function - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath- still executes, which results in a bad access error. I presume that this is because the array that the aforesaid function attempts to utilize has not been populated. This brings me to my question: Is there anyway that I can have the UITableView delegate methods delayed to avoid this? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"AlbumsCell"; //UITableViewCell *basicCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; AlbumsCell *cell = (AlbumsCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (!cell) { **// Here is where the Thread 1: EXC_BAD_ACCESS (code=2 address=0x8)** cell = [[[AlbumsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } Album *album = [_albums objectAtIndex:[indexPath row]]; [cell setAlbum:album]; return cell; }

  • Why is the GUID structure declared the way it is?

    - by alabamasucks
    In rpc.h, the GUID structure is declared as follows: typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; BYTE Data[8]; } GUID; I understand Data1, Data2, and Data3. They define the first, second, and third sets of hex digits when writing out a GUID (XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXX). What I never understood was why the last 2 groups were declared together in the same byte array. Wouldn't this have made more sense (and been easier to code against)? typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; WORD Data4; BYTE Data5[6]; } GUID; Anyone know why it is declared this way?

  • Why is numpy c extension slow?

    - by Bitwise
    I am working on large numpy arrays, and some native numpy operations are too slow for my needs (for example simple operations such as "bitwise" A&B). I started looking into writing C extensions to try and improve performance. As a test case, I tried the example given here, implementing a simple trace calculation. I was able to get it to work, but was surprised by the performance: for a (1000,1000) numpy array, numpy.trace() was about 1000 times faster than the C extension! This happens whether I run it once or many times. Is this expected? Is the C extension overhead that bad? Any ideas how to speed things up?

  • scala coalesces multiple function call parameters into a Tuple -- can this be disabled?

    - by landon9720
    This is a troublesome violation of type safety in my project, so I'm looking for a way to disable it. It seems that if a function takes an AnyRef (or a java.lang.Object), you can call the function with any combination of parameters, and Scala will coalesce the parameters into a Tuple object and invoke the function. In my case the function isn't expecting a Tuple, and fails at runtime. I would expect this situation to be caught at compile time. object WhyTuple { def main(args: Array[String]): Unit = { fooIt("foo", "bar") } def fooIt(o: AnyRef) { println(o.toString) } } Output: (foo,bar)

  • Replace strings differently depending if is enclosed in braces or not.

    - by peroyomas
    I want to replace all instances of an specific words between braces with something else, unless it is written between double braces, while it should show as is it was written with single braces without the filter. I have tried a code but only works for the first match. The rest are shown depending of the first one: $foo = 'a {bar} b {{bar}} c {bar} d'; $baz = 'Chile'; preg_match_all( '/(\{?)\{(tin)\}(\}?)/i', $foo, $matches, PREG_SET_ORDER ); if ( !empty($matches) ) { foreach ( (array) $matches as $match ) { if( empty($match[1]) && empty($match[3])) { $tull = str_replace( $match[0], $baz, $foo ); } else { $tull = str_replace( $match[0], substr($match[0], 1, -1), $foo ) ; } } } echo $tull;

  • Data not entering the table

    - by Luke
    //loop through usernames to add to league table for ($i = 0; $i < count($user); $i++) { //set some new variables in an array $username = $user[$i]; $squad = $team[$i]; //add details to league table if ( $username != "Ghost") { $database->addUsersToLeagueTable($username, $squad); } } I use this code to add to the league table, the following is more code: function addUsersToLeagueTable($username, $squad) { $q = "INSERT INTO `$_SESSION[comp_name]` ( `user` , `team` , `home_games_played` , `home_wins` , `home_draws` , `home_losses` ,`home_points, `home_goals_for` , `home_goals_against` , `away_games_played` , `away_wins` , `away_draws` , `away_losses` , `away_points` , `away_goals_for` , `away_goals_against` ) VALUES ( '$username', '$squad', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0')"; return mysql_query($q, $this->connection); } Can you see any obvious reason why this isn't happening? Thanks

  • Haskell - generating all paths between nodes

    - by user1460863
    I need to build a function, which return all paths between certain nodes. connect :: Int -> Int-> [[(Int,Int)]] Data.Graph library gives me usefull function 'buildG' which builds graph for me. If I call let g = buildG (1,5) [(1,2),(2,3),(3,4),(4,5),(2,5)], I will get an array where every node is mapped to his neighbours. An example: g!1 = [2] g!2 = [3,5] .. g!5 = [] I was trying to do it using list comprehensions, but I am not very good in haskell and I am getting typing error which I can't repair. connect x y g | x == y = [] | otherwise = [(x,z) | z <- (g!x), connect z y g] I don't need to worry at this moment about cycles. Here is what I want to get: connect 1 5 g = [[(1,2),(2,3),(3,4),(4,5)],[(1,2),(2,5)]]

  • How to test obtaining a list of files within a directory using RSpec?

    - by John Topley
    I'm pretty new to the world of RSpec. I'm writing a RubyGem that deals with a list of files within a specified directory and any sub-directories. Specifically, it will use Find.find and append the files to an Array for later output. I'd like to write a spec to test this behaviour but don't really know where to start in terms of faking a directory of files and stubbing Find.find etc. This is what little I have so far: it "should return a list of files within the specified directory" do end Any help much appreciated!

  • Accessing loop iteration in a sub-function?

    - by DisgruntledGoat
    I'm using the Google Maps API to plot several points on a map. However, in the click event function below, i is always set to 4, i.e. its value after iterating the loop: // note these are actual addresses in the real page var addresses = new Array( "addr 1", "addr 2", "addr 3", "addr 4" ); for (var i = 0; i < addresses.length; i++) { geocoder.getLatLng(addresses[i], function(point) { if (point) { var marker = new GMarker(point); map.addOverlay(marker); map.setCenter(point, 13); GEvent.addListener(marker, "click", function() { // here, i=4 marker.openInfoWindowHtml("Address: <b>" + addresses[i] + "</b>"); }); } }); } So when the marker displays it's using addresses[4] which is undefined. How do I pass the correct value of i to the function?

  • Fastest method for SQL Server inserts, updates, selects

    - by Ian
    I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

  • Is there a way to make this C# method shorter and more readable with the help of Linq?

    - by Hamish Grubijan
    The following works, but I figured - since it is all based on IEnumerable, Linq can come handy here is well. By the way, is there an equivalent to Directory.GetFiles() which would return an IEnumerable instead of the array? If it exists, then would it make the code run any faster? The last part of the question is inspired by Python language which favors lightweight generators over concrete lists. private IEnumerable<string> getFiles(string strDirectory, bool bCompressedOnly) { foreach (var strFile in Directory.GetFiles(strDirectory)) { // Don't add any existing Zip files since we don't want to delete previously compressed files. if (!bCompressedOnly || Path.GetExtension(strFile).ToLower().Equals(".zip")) { yield return strFile; } } foreach (var strDir in Directory.GetDirectories(strDirectory)) { foreach (var strFile in getFiles(strDir, bCompressedOnly)) { yield return strFile; } } }

  • Force memcached to write to all servers in pool

    - by Industrial
    Hi everyone, I have thought a bit on how to make sure that a particular key is distributed to ALL memcached servers in a pool. My current, untested solution is to make another instance of memcached, something like this: $cluster['local'] = array('host' => '192.168.1.1', 'port' => '11211', 'weight' => 50); foreach ($this->cluster() as $cluster) { @$this->tempMemcache = new Memcache; @$this->tempMemcache->connect($cluster['host'], $cluster['port']); @$this->tempMemcache->set($key, $value, $this->compress, $expireTime); @$this->tempMemcache->close(); } What is common sense to do in this case, when certain keys need to be stored on ALL servers for reliability?

  • CakePHP delete() function is not working

    - by Logic Artist
    Hello, Im just cracking open cakePHP (v1.3.2). I set it up on my local wamp server, seems to work fine except the delete() function doesn't work. I'm following their blog tutorial exactly, its as simple as it can be so I don't understand why its not working. Heres the function in my PostsController class: function delete($id = NULL) { $this->Post->delete($id); $this->Session->setFlash('The post with id: '.$id.' has been deleted.'); $this->redirect(array('action'=>'index')); } The "Delete" link's url looks like http://localhost/posts/delete/id:1 (where the id number matches the particular post, obviously). It redirects and sets the flash message, however there is no number where $id should be in the message, and the post isn't deleted. It seems the proper id is passed through the url, but I don't think it is getting into the function. I dont get it. Any ideas???

  • IndexedDB and Relationships

    - by Josh Johnson
    Can I create relationships between my object stores in IndexedDB? For example, I have two object stores: artist and album. An artist has a one-to-many relationship with an album. album.artistId relates the album to artist.id. I'm thinking along the lines of Hibernate here. I would like to do a query for artists and have the albums belonging to that artist returned as an array called artists on the album object. artist.albums = [];

  • Why are configuration arrays acceptible parameters in PHP and Javascript?

    - by RenderIn
    In most other OO languages it would be sacrilege to have each function receive a single associative array of Objects rather than enumerating each in the method signature. Why is it acceptable and commonly used in most popular frameworks for both of these languages to do this? Is there some justification beyond wishing to have concise method signatures? I do see a benefit in this -- that the API could remain unchanged as new, optional parameters are added. But Javascript and PHP already allow for optional parameters in their method signatures. If anything, it seems like Java or another OO language would benefit from this more... and yet I rarely see this pattern there. What gives?

  • using a tileset with canvas

    - by Anonymous
    Yeah so I'm lost from the get-go. Alright let's say I have a big image with every tile for a 2D top-down RPG game. They're all the same width and everything. What I don't know is how would I save every individual tile from that image to their own image data for use on the canvas? Basically I want to take a big image with all my tiles, choose squares throughout it to make images out of the tiles, and store each image as a variable in an array. So, how would I do this?

  • C++ toLowerCase Function won't work - Access violation

    - by misaizdaleka
    Hi, I have a simple function which takes an array of characters as an argument, and converts all the characters to lower case. However, I get a weird access violation error. Here's the code: void toLower(char *rec) { int i=0; while (rec[i]!='\0') { if (rec[i]>='A' && rec[i]<='Z') rec[i]='a'+rec[i]-'A'; //this is where I get an error - assigning the //the value to rec[i] is the problem i++; } } Can you tell me what's my mistake? Thanks

  • ZendFramework Zend_Form_Element_File setDestination vs rename filter

    - by bibstha
    The code says Zend_Form_element_File::setDestination() is depricated and to use the rename filter. However the rename filter is currently codes such that when path is set, only temporary name is given. Original filename is lost. <?php $file = new Zend_Form_Element_File(); $file->setDestination('/var/www/project/public'); ?> vs <?php $file = new Zend_Form_Element_File(); $file->addFilter('Rename', array('target' => '/var/www/project/public')); ?> Any solution to upload files so that it preserves original filename structure but checks for existing file and appends _1.ext or _2.ext?

  • How to store matrix information in MySQL?

    - by dedalo
    Hi, I'm working on an application that analizes music similarity. In order to do that I proccess audio data and store the results in txt files. For each audio file I create 2 files, 1 containing and 16 values (each value can be like this:2.7000023942731723) and the other file contains 16 rows, each row containing 16 values like the one previously shown. I'd like to store the contents of these 2 file in a table of my MySQL database. My table looks like: Name varchar(100) Author varchar (100) in order to add the content of those 2 file I think I need to use the BLOB data type: file1 blob file2 blob My question is how should I store this info in the data base? I'm working with Java where I have a double array containing the 16 values (for the file1) and a matrix containing the file2 info. Should I process the values as strings and add them to the columns in my database? Thanks

  • PHP object help -> unexpected T_OBJECT_OPERATOR

    Please help me understand: print gettype(new CustomerObject()) prints: "object" (so it is an object) BUT print gettype((new CustomerObject())->get_customer()); prints: unexpected T_OBJECT_OPERATOR If I do it over two lines it works fine $object = new Customer($order->customer_id); print gettype($object); prints: object $customer = $object->get_customer(); print gettype($customer); prints: array It appears that the lines cannot be joined into a single call. Is this correct? and what is the logic behind that?

  • Programmatically get valid switch/case values

    - by craigim
    When MATLAB scans through cases in a switch/case block, does it remember the values that it skips, and is it possible to access that list? I have a few functions with long switch\case block and I would like to have them return a list of valid case values if they make it down to otherwise. For instance, I have a function that returns a set of optical constants for a material. It currently has about 20 different materials and it is growing as I consider new ones. I realize I can brute-force it and just re-type all of the valid cases into a cell array under otherwise and have the function throw an error and return the list of valid responses, but maintaining both lists without errors or laziness creeping in over time is challenging.

  • why assert_equal() in Ruby on Rails sometimes seem to compare by Identity and sometimes by value?

    - by Jian Lin
    it was very weird that yesterday, I was do an integration test in Rails and assert_equal array_of_obj1, array_of_obj2 # obj1 from db, obj2 created in test and it failed. The values shown inside the array and objects were identical. If I change the test to assert array_of_obj1 == array_of_obj2 Then it will pass. But today, the first test actually passed. What reason could it be? Is assert_equal always using == or .equal? in Rails 2.2 or 2.3.5?
