  • What license (eg. BSD, GPL, etc) can I use for an open source app that can be used commerically, for free?

    - by Pure.Krome
    Hi folks, I've got an application on Codeplex. It's based on some other free open source code which comes with a BSD license. As such, people keep asking if they can use my open source code/library in their commercial apps. I want them to be able to, provided they give credit to the source app (the project which i based my code, from .. and that has the BSD license) and also my code. They can take my code and do whatever (fork it, etc).. Just make sure they give credit, of course. So - what license could I use? Currently, I've set it to be GPL .. so is that ok? NOTE: Yes yes, I know that any answers are not from a lawyer and it's just all personal thoughts and I need to consult a special lawyer if I want some professional advice, etc. etc. I'm happy to take that risk, here.

  • Strange behaviour of mb_detect_order() in PHP

    - by termopro
    I would like to detect encoding of some text (using PHP). For that purpose i use mb_detect_encoding() function. The problem is that the function returns different results if i change the order of possible encodings with mb_detect_order() function. Consider the following example $html = <<< STR ????????????????????????????????????????????????????????????????????????????????????????????????????????? STR; mb_detect_order(array('UTF-8','EUC-JP', 'SJIS', 'eucJP-win', 'SJIS-win', 'JIS', 'ISO-2022-JP','ISO-8859-1','ISO-8859-2')); $originalEncoding = mb_detect_encoding($str); die($originalEncoding); // $originalEncoding = 'UTF-8' However if you change the order of encodings in mb_detect_order() the results will be different: mb_detect_order(array('EUC-JP','UTF-8', 'SJIS', 'eucJP-win', 'SJIS-win', 'JIS', 'ISO-2022-JP','ISO-8859-1','ISO-8859-2')); die($originalEncoding); // $originalEncoding = 'EUC-JP' So my questions are: Why is that happening ? Is there a way in PHP to correctly and unambiguously detect encoding of text ?

  • Serialize object from within

    - by Maximus
    I have the class testClass which has the method save. This method saves object to a database. But it needs to serialize object before saving. How can I serialize object from within the class to do that? class testClass { private $prop = 777; public function save() { $serializedObject = serialize(self); DB::insert('objects', array('id', 'object')) ->values(array(1, $serializedObject)) ->execute(); } } serialize(self) obviously doesn't work.

  • jquery integrate form parameter in one object

    - by jesse
    There are many forms in my page. I want to merge them in one object and submit them in one object. But I find serializeArray() or serialize() do not match my request, the serializeArray function will generate a array object and serialize is used by get model, it is not an object. is there a jquery or local function can merge them in one object. I have one solution but it is not perfect, loop the array object generated by serializeArray, use $.extend to merge them in one object. is there a better method? kindly help, thanks.

  • jquery: find common elements in 2 sets of divs

    - by tsiger
    For a markup like this: <div id="set1"> <div id="100">a div</div> <div id="101">another div</div> <div id="102">another div 2</div> <div id="120">same div</div> </div> <div id="set2"> <div id="105">a different div> <div id="101">another div</div> <div id="110">more divs</div> <div id="120">same div</div> </div> As you can see both #set1 and #set2 contain 2 divs with the same id (101, 120). Is it possible somehow with jQuery to find the common elements and add a class to the divs in #set1 that have the same id with divs in #set2? In other words after the script run the above code would look like this: <div id="set1"> <div id="100">a div</div> <div id="101" class="added">another div</div> <div id="102">another div 2</div> <div id="120" class="added">same div</div> </div> <div id="set2"> <div id="105">a different div> <div id="101">another div</div> <div id="110">more divs</div> <div id="120">same div</div> </div> EDIT playing around with it i did something but i am not sure it can go anywhere. I created an array with the ids in both sets and in Firebug i can see an array with the values var arrEl = []; $('#set1 div, #set2 div').each( function(index) { var id = $(this).attr('id'); arrEl.push(id); //maybe somehow check the array for the values that appear twice, and add the class to the //matching divs? });

  • How do I change the background image of my app?

    - by user356387
    Hello I have looked around and found some code which so called chooses an image from an array of image objects, but cant find an explanation. I would like to make my app have a background image and the user can select next and previous buttons to scroll through some full screen images, setting them as the background image as they scroll. I know how to do this in java, but cant seem to do it for this app. How or what code is linked to a next button to grab the next image in the array and reverse for the back button? Then that needs to be displayed obviously. I have used a layered architecture with a MVC style approach but cant seem to put it together with Objective-C. Would the buttons call the appropriate methods of the so called delegates, which the delegates handle fetching and returning the Images? Would the buttons use the returned images and actually handle the redrawing? I would really appreciate the help. Regards Jarryd

  • How to assign variable dynamically to php list function

    - by ravisoni
    What I am doing that I want to generate a list based on how many items are in an array, so I have counted the items and loop over them, create a number based var and construct a string $var which contains $a1,$a2.... and assigns the $var to list list($var) and tried to access $a1 but it gives me the error "Undefined variable: a1" Is there any other way to do it? Here is my code: $arr = array('1','2','3'); $listsize = count($arr); $var=''; for($i=1;$i<=$listsize;$i++){ $var.='$a'.$i; if($i!=$listsize){ $var.=','; } } list($var) = $arr; echo $a1;

  • How to choose programaticaly the column to be queried by Linq using PropertyInfo???

    - by Richard77
    Hello, I would like to control how linq querries my database programaticaly. For instance, I'd like to query the column X, column Y, or column Z, depending on some conditions. First of all, I've created an array of all the properties inside my class called myPropertyInfo. Type MyType = (typeOf(MyClass)); PropertyInfo[] myPropertyInfo = myType.GetProperties( BindingFlags.Public|BindingFlags.Instance); The myPropertyInfo array allows me to access each property details (Name, propertyType, etc) through the index*[i]* Now, how can I use the above information to control how linq queries my DB? Here's a sample of a querry I'd like to exploit. var myVar = from tp in db.MyClass select tp.{expression}; Expression using myPropertyInfo[i] to choose which property(column) to query. I'm not sure if that's the way of doing it, but if there's another way to do so, I'll be glad to learn. Thanks for helping.

  • strategy to allocate/free lots of small objects

    - by aaa
    hello I am toying with certain caching algorithm, which is challenging somewhat. Basically, it needs to allocate lots of small objects (double arrays, < 256 elements), with objects accessible through mapped value, map[key] = array. time to initialized array may be quite large, generally more than 10 thousand cpu cycles. By lots I mean around gigabyte in total. objects may need to be popped/pushed as needed, generally in random places, one object at a time. lifetime of an object is generally long, minutes or more, however, object may be subject to allocation/deallocation several times during duration of program. What would be good strategy to avoid memory fragmentation, while still maintaining reasonable allocate deallocate speed? I am using C++, so I can use new and malloc. Thanks. I know there a similar questions on website, http://stackoverflow.com/questions/2156745/efficiently-allocating-many-short-lived-small-objects, are somewhat different, thread safety is not immediate issue for me.

  • I am getting duplicates in UITableView, cellForRowAtIndexPath

    - by Martol1ni
    I am getting duplicates of my array, and wrongly displayed cells in this method: Here I am initializing the array, and adding it to the tableView: NSArray *sectionsArray = [NSArray arrayWithObjects: @"Location", @"Front Post", @"Front Fixing", @"Front Footplate", @"Rear Post", @"Read Fixing", @"Rear Footplate", @"Horizontal Bracing", @"Diagonal Bracing", @"Front Beam", @"Front Lock", @"Rear Beam", @"Rear Lock", @"Guard", @"Accessories", @"Comments", @"Off load ref", @"Loc Empty", @"Loc Affected", nil]; [_tableArray setObject:sectionsArray atIndexedSubscript:2]; [_tableView reloadData]; For some weird reason there are always the 4th object that is messed up, and is either duplicated, or do not have the views from IB. Here is the cellForRowAtIndexPath: method: - (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell; if (indexPath.section == 2) { cell = [tableView dequeueReusableCellWithIdentifier:@"EntryCell"]; cell.tag = indexPath.row; UILabel *label = (UILabel *)[cell viewWithTag:3]; [label setText:[[_tableArray objectAtIndex:2] objectAtIndex:indexPath.row]]; } return cell; } I have logged the string [[_tableArray objectAtIndex:2] objectAtIndex:indexPath.row], and it logs the right string.

  • MySQL Query : Advise Needed.

    - by Rachel
    "SELECT id as Id from dbTable WHERE code = ? AND CURDATE() BETWEEN start_date AND end_date AND offerId IN ('12321', '12124')"; //Passing arguments for the query $args = array_merge(array(51342),$offerid); //Execute the prepared query $statement->execute($args); Now array(51342) represents combination of code+value, aside my database has value, code columns and so I want a query which would look logically like "SELECT id as Id from dbTable WHERE code and value (Note here I do not know the syntax, what am looking at is (code+value = ?), please advise on query) = ? AND CURDATE() BETWEEN start_date AND end_date AND offerId IN ('12321', '12124')";

  • Squid logs on mongodb

    - by user306241
    Hi, I'm planning to log my squid instances to a mongodb, but the actual problem is that we have a huge traffic to be logged, every access authenticated with user/pass. Eventually we have to make some reports based on logs. I was thinking to insert the logs distributed by months and by users, so my collection will look like this: {month: 'april', users: [{user: 'loop0', logs: [{timestamp: 12345678.9, url: 'http://stackoverflow.com/question/ask', ... }]}] So if I want to generate my reports based on the month of april I just have to get the right month instead of looking in zillions of lines to fetch the lines that timestamp match between April, 1 and April, 30. Of course this type of insert will be slower than just insert the log line directly. So my question is: is there a best way to do this? Nowadays we have around 12 million lines of log by day.

  • localhost/live - detect by HTTP_HOST

    - by Adam Kiss
    Hello, let's say I develop locally and debug small things on live server. Is it good idea to have something like this in my code? : $is_local = (strpos($_SERVER['http_host'], 'localhost') !== false); define ('DEBUG',$is_local); And then use it through my code, when setting stuff? $mysql_settings = (DEBUG) ? array(/*localhost settings*/) : array(/*live settings*/); This way, I can use the same files live and on localhost, so I can sync without any fear of having wrong e.g. connection settings on live server. Is it good or wrong idea?

  • In Perl, is there a built in way to compare two arrays for equality?

    - by Bill
    I have two arrays of strings that I would like to compare for equality: my @array1 = ("part1", "part2", "part3", "part4"); my @array2 = ("part1", "PART2", "part3", "part4"); Is there a built-in way to compare arrays like there is for scalars? I tried: if (@array1 == @array2) {...} but it just evaluated each array in scalar context, and so compared the length of each array. I can roll my own function to do it, but it seems like such a low-level operation that there should be a built-in way to do it. Is there? Edit: sadly, I don't have access to 5.10+ or optional components.

  • Access a static variable by $var::$reference

    - by chuckg
    I am trying to access a static variable within a class by using a variable class name. I'm aware that in order to access a function within the class, you use call_user_func(): class foo { function bar() { echo 'hi'; } } $class = "foo"; all_user_func(array($class, 'bar')); // prints hi However, this does not work when trying to access a static variable within the class: class foo { public static $bar = 'hi'; } $class = "foo"; call_user_func(array($class, 'bar')); // nothing echo $foo::$bar; // invalid How do I get at this variable? Is it even possible? I have a bad feeling this is only available in PHP 5.3 going forward and I'm running PHP 5.2.6. Thanks.

  • Python point lookup (coordinate binning?)

    - by Rince
    Greetings, I am trying to bin an array of points (x, y) into an array of boxes [(x0, y0), (x1, y0), (x0, y1), (x1, y1)] (tuples are the corner points) So far I have the following routine: def isInside(self, point, x0, x1, y0, y1): pr1 = getProduct(point, (x0, y0), (x1, y0)) if pr1 >= 0: pr2 = getProduct(point, (x1, y0), (x1, y1)) if pr2 >= 0: pr3 = getProduct(point, (x1, y1), (x0, y1)) if pr3 >= 0: pr4 = getProduct(point, (x0, y1), (x0, y0)) if pr4 >= 0: return True return False def getProduct(origin, pointA, pointB): product = (pointA[0] - origin[0])*(pointB[1] - origin[1]) - (pointB[0] - origin[0])*(pointA[1] - origin[1]) return product Is there any better way then point-by-point lookup? Maybe some not-obvious numpy routine? Thank you!

  • Arrays and application data

    - by s0mmer
    Hello everyone, At the moment i'm making an application where it is possible to make profiles with different settings. Which datatypes would you recommend me saving these information in? I have a table which is showing the profile name and the version number. But for each profile there need to be stored more information. Therefore the idea i'm working on have 2 arrays. 1 for all the profile information and 1 who is being made when loading the information. The second array is the one going to be showed in the table. Because the table doesnt show all the stored information. .. but this seems kinda stupid. Is there a more suitable method for saving the information in like 1 array, and just pass part of the data to the tableview?

  • login with users, groups and permissions

    - by Dan Bemowski
    OK, I have a set of tables that I want to use for my user logins. I am guessing that I need a separate model for each table in the database. My tables are as follows: Users - user information such as first and last name, groups_id, status, etc... groups - defines the user groups with id, name, description permissions - defines a list of permissions that a group can have permission_assignments - groups_id and permissions_id. many to many relationship table I am not sure how to go about populating an array that would contain the list of permissions that a user would have based on the group they are in after a successful login. Basically, a user belongs to a group, and the group gets assigned permissions. I want to then be able to validate functions/methods based on weather the logged in user has certain permissions. Any help is appreciated

  • Display random image when page loads without utilizing onload in the body tag

    - by Peachy
    I'm trying to create a fairly simple piece of JavaScript that displays a random image from an array each time the page loads. I need to figure out a way to get this running without adding code to the body tag. Is there a way to accomplish this without, say, an onload funtion placed in the body tag? Here's what I have that relies on the onLoad: ImageSwitch=new Array(); ImageSwitch[0]='1.jpg'; ImageSwitch[1]='2.jpg'; ImageSwitch[2]='3.jpg'; ImageSwitch[3]='4.jpg'; function swapImage() { document.getElementById("theImage").setAttribute("src", ImageSwitch[ Math.round(Math.random()*3)]) } Any alternative ideas to accomplish this? Thanks.

  • How do I link to another action in Magento whilst passing a parameter to the controller?

    - by desbest
    I need to pass a parameter, because I would like to redirect back to the module and query string of the current page. So I can get from showdown/index?id=35 --click--- showdown/vote?id=1 showdown/vote?id=1 --redirect-- showdown/index?id=35 The vote action is not seen. (The redirect method doesn't work as it takes the index.php url only and no actions, and I cannot find a helper in Magento for creating hyperlinks.) Does Magneto have a link helper for this? Example of stuff I want: <a href="<?php echo Mage::Helper->Link->($url, $array); ?> then $array or whatever variables gets sent to the controller.

  • Programmatic gradient stops with Javascript

    - by TomcatExodus
    Working with Javascript (jQuery), given 2 color values (2033ff and 3300a0 for example) how can I determine certain gradient stops between them? Reason being is, I intend on using an array of color values: 0 => '000000' 8400 => 'f0ff00' 44000 => '2033ff' 68400 => '3300a0' There being 86400 seconds in a day, 12:00AM maps to 0, and 11:59PM maps to 86399. As time passes, the background color of a specified element changes to the appropriate color in gradient list via window.setInterval(function(e){ ... }, 1000). For example 2:32:11PM = 52331, which from the example would be somewhere between 2033ff and 3300a0. I don't need to populate the array with the values (unless that would be easier) but instead use the index and value as references.

  • How can I find if an arbitrary process is running under wow64?

    - by LCC
    I need a tool which will discover whether an arbitrary process is running in x86 or x64 mode on a machine. I need to do this programatically from C++, based on a process ID. There has to be some way to do this (as you can clearly see it from the task manager). Does anyone know of a windows api that will tell you, given a process ID, whether the application is running under wow64? Another approach would be to figure out, based on the process id, the executable name/path that is running and try to read the PE headers out of the file. Does anyone have a code snippet that would accomplish that?
