• Can I insert a style tag and contents from a view with CakePHP?

  - by Richard

  From what I can see, CakePHP makes it easy to link to a CSS file in a view with the following: echo $html->css('my-css-filename',null,array(),FALSE); But what if I don't want to exclusively use hardcoded files? How can I get it to create a style tag with some dynamically generated rules in e.g. <style type="text/css" media="all">p {font-size:1.5em}</style> I am trying to do this in a view file, I'd like the CSS to be placed in the head tag, and I'm using CakePHP 1.2.7

• Sort vector<int>(n) in O(n) time using O(m) space?

  - by Adam

  I have a vector<unsigned int> vec of size n. Each element in vec is in the range [0, m], no duplicates, and I want to sort vec. Is it possible to do better than O(n log n) time if you're allowed to use O(m) space? In the average case m is much larger than n, in the worst case m == n. Ideally I want something O(n). I get the feeling that there's a bucket sort-ish way to do this: unsigned int aux[m]; aux[vec[i]] = i; Somehow extract the permutation and permute vec. I'm stuck on how to do 3. In my application m is on the order of 16k. However this sort is in the inner loops and accounts for a significant portion of my runtime.

• Java-Counting occurrence of word from huge textfile

  - by Naveen

  I have a text file of size 115MB. It consists of about 20 million words. I have to use the file as a word collection, and use it to search the occurrence of each user-given words from the collection. I am using this process as a small part in my project. I need a method for finding out the number of occurrence of given words in a faster and correct manner since i may use it in iterations. I am in need of suggestion about any API that i can make use or some other way that performs the task in a quicker manner. Any recommendations are appreciated.

• Is there an HTML code that can make my background picture transparent and my text non-transparent?

  - by user1831312

  Okay so I've been typing some HTML code for a technology class that I need to satisfy for my Education major. This is what i have for my background: body { background-image:url('islandbeach.jpg'); background-repeat:repeat; background-position:center; background-attachment:fixed; background-size:cover; } Now, I want to make my background transparent or faded so I can see the text and the other image that I have. The background is too colorful to be able to see the words without having to squint. Are there any HTML codes that can do this for me? I am not a pro at this stuff, I've just been following everything my professor has told me to do so please explain stuff in baby steps if you do have an answer. Thank you so so much!

• MySQL log files deletion

  - by aneez

  I have a master and slave database running on different nodes. The master DB is subjected to huge no. of inserts/updates. The master DB size is close to 6 GB, while the log files are now occupying a space of more than 120 GB. I am running out of disk space and need to get rid of the log files. Will deleting the log files in anyway affect the slave DB ? Presently, the slave is just a couple of seconds behind the master. Is there someplace where I can see what steps I need to follow to delete those files eg. 1)Shut down the slave 2)Shut down the master 3)Delete the log files 4)Start the Master 5)Start the Slave Do I need to inform the slave that the log files have been deleted ?? If yes, what is the way to do it ? Any help would be appreciated. Thanks

• Full background using :cover; makes adds horizontal scroll

  - by user1907341

  I am working on a website which needs a header with full background image & 650 height. At the moment i am using background-size: cover; property with 100% width. While, it's working it leaves an awkward horizontal scroll of about 50px on right side. Which is lot more prominent in smaller resolutions. I tried applying background to body instead of header div too. But same thing happens there as well. You can see a preview here - http://nitingarg.com/projects/tfe/

• Skip reading strings in matlab

  - by Paul

  Is there is easy command in matlab which prevents program from crashing when it reads characters? I use xlsread to read a (20 400) matrix data , the first row and column get disregarded as they have headers, so that: data = xlsread ( ' C:\file.xls') results in data with a size of (19 399). I have a problem, some cells have missing data and it's written ' missing' and on some data sets i have headers reappear in middle. Is there a way to skip these characters without the program crashing and me having to open the file in excel and deleting those fields? Thanks

• Removing an element from an array (PHP)

  - by morpheous

  I want to remove an element from a PHP array (and shrink the array size). Just looking at the PHP docs, it seems this can be done using array_slice() and array_merge() so I am guessing (off the top of my head) that some combination of array_merge() and array_slice will work. However, array_slice() requires an index (not a key), so I'm not sure how to quickly cobble these functions together for a solution. Has anyone implemented such a function before?. I'm sure it must be only a few lines long, but I cant somehow get my head around it (its been one of those days) ... Actually, I just came up with this cheesy hack when writing up this question.... function remove_from_array(array $in, value) { return array_diff($in, (array)$value); } too ugly? or will it work (without any shocking side effects)?

• Writing To The Response in Rails? (Like "echo" in PHP)

  - by Yar

  I know that I can do this in Rails: <%="hello" %> but is there any way to do this <% echo "hello" %> and get it to show up in the response? I have tried response.write which almost worked, but did not... Edit: print or puts do not do it, because I do not want to write to the console. I want to write to the browser/HTTP client. Edit: Here is an example: <% unless @research_activities.size == 0 concat(render(:partial => 'list')) end %> Why would I want to include two closing tags just to do that? It reads nicely in code, doesn't it?

• Why can't I set a layout for a page in a QStackedWidget in designer?

  - by cppguy

  Steps to reproduce in designer for Qt 4.8.0 I create a new dialog form in Qt Designer I add a QStackedWidget to the dialog I set the layout of the dialog to make the stacked layout size with the dialog I add a few controls to page one in the stacked widget I select the first page in the stacked widget in the right hand tree view of controls The icon next to that page (which is a QWidget) shows the page is missing a layout When I click one of the layout buttons above, it doesn't change the layout of the page QWidget, it changes the layout of the dialog even though I had explicitly selected the page. Is this a bug in designer? Am I missing something? I really don't want to add the layouts programatically as that prevents me from being able to layout the pages in designer in the same .ui file

• Simple list traversal in C++

  I have a code for simple list traversal. Could you please help me out to do this traversal more efficiently! mylist::traverse() { // this code traverses a list by index order of the elements (for int i=1; i<= thelist.size(); i++ ) /* find index numbers */ { int count=0; /* counter to find index */ Node * cursor; for ( cursor = head_ptr; cursor !=NULL ||count<i; cursor=cursor->link() ) { count++; } if ( cursor != NULL ) cout << “index: “ << i << “ value: “ << cursor->data() << endl; } }

• Why would you use a MyObject[] internally, but expose a List<MyObject>?

  - by timmyd

  I have come across a class that has an immutable property: MyObject[] allObjs The property is initialized like this: List<MyObject> objs = createAllMyObjects(); allObjs = objs.toArray(new MyObject[objs.size()]); When it is exposed through the accessor, it's done as a List: public List<MyObject> getAllMyObjects() { return Collections.unmodifiableList(Arrays.asList(allObjs)); } Why would a programmer do this? Is there a benefit that I don't know about? Performance is not a concern, as the array of objs will only ever number in a few dozen elements. It seems that we are going round and round in circles. The class is a sort of factory, so it's got a private constructor and exposes only static methods (not sure if this could be a reason for the madness).

• jQuery center image

  - by Aaron Moodie

  I've got an issue where I was tying to center images using the jQuery Cycle plugin. I found this solution, but it wasn't working on single images (there isn't always 2 images), so I wrote my own little bit of code, which seems to be working, except it sometimes doesn't subtract the height of the image from the height of the div, and so i end up with a margin of 310px. var $image_cnt = $("#images > img").size(); if($image_cnt < 2) { var $single_img = $("#images").children(':first-child'); var h = $single_img.height(); $single_img.css({ marginTop: (620 - h) / 2, }); $(".next").css("display","none"); $(".prev").css("display","none"); } I haven't used jQuery much, and just wanted to know if I'd missed something simple, or had written something wrong, which is why the marginTop wasn't playing nice.

• IE8 $('body').width() is 0 on $(window).load()

  - by allicarn

  On $(document).ready I run through a for loop twice and alert out the body's width ($('body').width();) each time through. I get a value I would expect (ex. 1092). On $(window).load I run through another for loop twice, also alerting out the body's width each time through. I get 0 the first time through (and the page looks completely blank behind the alert), and then a value I would expect the second time through (ex. 1092). This is an issue I am not able to replicate in a stripped-down example, nor any other browser (Chrome, Safari, Firefox, IE9, IE10). Does anyone have any ideas, or other things that I could test for? I am using $(window).load to cut up some divs based on their width, which is based on their font size, which is based on a webfont (which isn't necessarily loaded by the time $(document).ready fires).

• PHP Undefined index - Occuring when the variable has a value in it

  - by Adam

  I have the following code that is being used to successfully upload images: $fileName = $_FILES['file']['name']; $fileSize = $_FILES['file']['size']; $fileType = $_FILES['file']['type']; $fileTmp = $_FILES['file']['tmp_name']; list($origWidth, $origHeight) = getimagesize($fileTmp); The catch is I'm getting an 'Undefined index' on each line. I have print_r($_FILES) just before this code and each array variable exists and I've echo out varibles like $fileName and can see each has a value. Also I have put this before this code block and it makes no difference: $fileName = $fileSize = $fileType = $fileTmp = ''; Any suggestions how I can ensure these variables are defined? thankyou

• C++ - Implementing my own stream

  - by HardCoder1986

  Hello! My problem can be described the following way: I have some data which actually is an array and could be represented as char* data with some size I also have some legacy code (function) that takes some abstract std::istream object as a param and uses that stream to retrieve data to operate. So, my question is the following - what would be the easy way to map my data to some std::istream object so that I can pass it to my function? I thought about creating a std::stringstream object from my data, but that means copying and (as I assume) isn't the best solution. Any ideas how this could be done so that my std::istream operates on the data directly? Thank you.

  I put increment date of the calendar and add into arraylist, but when i loop them out, the date is all same. Calendar a = Calendar.getInstance(); ArrayList<Calendar> b = new ArrayList<Calendar>(); for (int i=0; i<3; i++) { a.add(Calendar.DATE, i>0 ? 1 : 0); b.add(a); } for (int i=0; i<b.size(); i++){ Log.d("xxx", "test=" + b.get(i)); } suppose i wan 10/11/2012, 11/11/2012, 12/11/2012 but it come out like 12/11/2012, 12/11/2012, 12/11/2012 Anyone know how to solve this?

• Best way to convert Stream (of unknown length) to byte array, in .NET?

  - by Frank Hamming

  Hello, I have the following code to read data from a Stream (in this case, from a named pipe) and into a byte array: // NPSS is an instance of NamedPipeServerStream int BytesRead; byte[] StreamBuffer = new byte[BUFFER_SIZE]; // defined elsewhere (less than total possible message size, though) MemoryStream MessageStream = new MemoryStream(); do { BytesRead = NPSS.Read(StreamBuffer, 0, StreamBuffer.Length); MessageStream.Write(StreamBuffer, 0, BytesRead); } while (!NPSS.IsMessageComplete); byte[] Message = MessageStream.ToArray(); // final data Could you please take a look and let me know if it can be done more efficiently or neatly? Seems a bit messy as it is, using a MemoryStream. Thanks!

• Is this a php memory leak?

  - by mseifert

  I have memory_get_usage() in the footer of my page and with each refresh of the page, I watch it increase by about 100k each time. My page load creates many objects and destroys them when done . My parent objects each have __destruct() which uses unset() with all child objects. Child objects with a reference back to the parent, have __destruct() to unset() these references. Inserting memory_get_usage() before and after processing different parts of my page only tells me how much of the total usage was added due to that part of the script. How do I go about determining what memory is lost and not recycled for garbage collection after the page finishes loading? I have one global $_SESSION var containing objects storing user info, but have verified using strlen(serialize($object)) that this object is not growing in size. I presume that what I am seeing is a memory leak and that php garbage collection should be in effect after the script ends. Any ideas how to debug this?

• Python if statement not working as expected

  - by Chris Esposito

  I'm searching for a string in a website and checking to see if the location of this string is in the expected location. I know the string starts at the 182nd character, and if I print temp it will even tell me that it is 182, however, the if statement says 182 is not 182. Some code f = urllib.urlopen(link) #store page contents in 's' s = f.read() f.close() temp = s.find('lettersandnumbers') if (htmlsize == "197"): #if ((s.find('lettersandnumbers')) == "182"): if (temp=="182"): print "Glorious" doStuff() else: print "HTML not correct. Aborting." else: print htmlsize print "File size is incorrect. Aborting."

• Find largest rectangle containing only zeros in an N&times;N binary matrix

  - by Rajendra

  Given an NxN binary matrix (containing only 0's or 1's), how can we go about finding largest rectangle containing all 0's? Example: I 0 0 0 0 1 0 0 0 1 0 0 1 II->0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 <--IV 0 0 1 0 0 0 IV is a 6×6 binary matrix; the return value in this case will be Cell 1: (2, 1) and Cell 2: (4, 4). The resulting sub-matrix can be square or rectangular. The return value can also be the size of the largest sub-matrix of all 0's, in this example 3 × 4.

• Git: Removing the object(s) associated with an old commit

  - by user362893

  A couple of months ago I added and committed a release tarball to a git code repository. A couple of commits later, I removed the file and committed the removal. This one file was nearly 10x the size of the whole repository, so the presence of that file in .git slows cloning down significantly. At this point there have been hundreds of commits since the pair of commits that added and removed the file. Is there a way to remove the two commits which cancel out (the add and the remove) and also remove the copy of the file in .git, without hosing the repository? Thanks..
