  • Is there a good .Net CSS aggregator that combines style sheets and minifies them?

    - by vfilby
    I am looking to see if there is an open source/free project that provides a CSS manager. I am looking for this mainly for performance tweaking and hoping there is a readymade project rather than building from scratch. Features I am looking for include: Combines multiple .css files into a single css file Optionally minifies the resulting .css file Works well with .Net (a user control, custom handler, etc) Is there a project out that that handles this?

  • MVC and jQuery data retrieval.

    - by user337542
    Hello, I am using mvc and jQuery and I am trying to display someone's profile with some additional institutions that the person belongs to. I am new to this but I've done something like this in ProfileControler: public ActionResult Institutions(int id) { var inst = fr.getInstitutions(id); return Json(inst); } getInstitutions(id) returns Institution objects(with Name, City, Post Code etc.) Then in a certain View I am trying to get the data with jQuery and display them as follows: $(document).ready(function () { $.post("/Profile/Institutions", { id: <%= Model.Profile.userProfileID %> }, function (data) { $.each(data, function () { var new_div = $("<div>"); var new_label = $("<label>"); new_label.html(this.City); var new_input_b = $("<input>"); new_input_b.attr("type", "button"); new_div.append(new_label); new_div.append(new_input_b); $("#institutions").append(new_div); }); }); }); $("#institutions") is a div where i want to display all of the results. .post works correct for sure because certain institutions are retrieved from database, and passed to the view as Json result. But then I am affraid it wont itterate with .each. Any help, coments or pointing in some direction would be much appriciated

  • Defining your own Ord for a data type

    - by mvid
    I am attempting to make some data structures to solve a graph puzzle. I am trying to define an edge's comparison criteria, but I am not sure how. So far: data Edge = Edge (Set String) Bool How do I tell let the compiler know that I want edges to be declared equal if they have identical sets of strings, and not have equality have anything to do with the boolean value?

  • Avoid an "out of memory error" in Java(eclipse), when using large data structure?

    - by gnomed
    OK, so I am writing a program that unfortunately needs to use a huge data structure to complete its work, but it is failing with a "out of memory error" during its initialization. While I understand entirely what that means and why it is a problem, I am having trouble overcoming it, since my program needs to use this large structure and I don't know any other way to store it. The program first indexes a large corpus of text files that I provide. This works fine. Then it uses this index to initialize a large 2D array. This array will have nXn entries, where "n" is the number of unique words in the corpus of text. For the relatively small chunk I am testing it on(about 60 files) it needs to make approximately 30,000x30,000 entries. this will probably be bigger once I run it on my full intended corpus too. It consistently fails every time, after it indexes, while it is initializing the data structure(to be worked on later). Things I have done include: revamp my code to use a primitive "int[]" instead of a "TreeMap" eliminate redundant structures, etc... Also, I have run eclipse with "eclipse -vmargs -Xmx2g" to max out my allocated memory I am fairly confident this is not going to be a simple line of code solution, but is most likely going to require a very new approach. I am looking for what that approach is, any ideas? Thanks, B.

  • Java converting to Jython-Getting a class object within itself

    - by Bggreen
    I am attempting to convert Java code to Jython and am using the apache Log and LogFactory imports. I am attempting to emulate Foo.class in Jython The chunk of code is as follows: in Java import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class MyClass { private static final Log log = LogFactory.getLog(MyClass.class); public MyClass(Document dom) { //code } How can I emulate this same behavior of MyClass.class in Jython/Python?

  • Cilk or Cilk++ or OpenMP

    - by Aman Deep Gautam
    I'm creating a multi-threaded application in Linux. here is the scenario: Suppose I am having x instance of a class BloomFilter and I have some y GB of data(greater than memory available). I need to test membership for this y GB of data in each of the bloom filter instance. It is pretty much clear that parallel programming will help to speed up the task moreover since I am only reading the data so it can be shared across all processes or threads. Now I am confused about which one to use Cilk, Cilk++ or OpenMP(which one is better). Also I am confused about which one to go for Multithreading or Multiprocessing

  • Should I go along with my choice of web hosting company or still search?

    - by Devner
    Hi all, I have been searching for a good website hosting company that can offer me all the services that I need for hosting my PHP & MySQL based website. Now this is a community based website and users will be able to upload pictures, etc. The hosting company that I have in mind, currently lets me do everything... let me use mail(), supports CRON jobs, etc. Of course they are charging about $6/month. Now the only problem with this company is that they have a limit of 50,000 files that can exist within the hosting account at any time. This kind of contradicts their frontpage ad of "UNLIMITED SPACE" on their website. Apart from this, I know of no other reason why I should not go with this hosting company. But my issue is that 50,000 file limit is what I cannot live with, once the users increase in significant number and the files they upload, exceed 50,000 in number. Now since this is a dynamic website and also includes sensitive issues like payments, etc. I am not sure if I should go ahead with this company as I am just starting out and then later switch over to a better hosting company which does not limit me with 50,000 files. If I need to switch over once I host with this company, I will need to take backups of all the files located in my account (jpg, zip, etc.), then upload them to the new host. I am not aware of any tools that can help me in this process. Can you please mention if you know any? I can go ahead with the other companies right now, but their cost is double/triple of the current price and they all sport less features than my current choice. If I pay more, then they are ready to accommodate my higher demands. Unfortunately, the company that I am willing to go with now, does NOT have any other higher/better plans that I can switch to. So that's the really really bad part. So my question(s): Since I am starting out with my website and since the scope of users initially is going to be less/small, should I go ahead with the current choice and then once the demand increases, switch over to a better provider? If yes, how can I transfer my database, especially the jpg files, etc. to the new provider? I don't even know the tools required to backup and restore to another host. (I don't like this idea but still..) Should I go ahead and pay more right now and go with better providers (without knowing if the website is going to do really that well) just for saving myself the trouble of having to take a backup of the 50,000 files and upload to a new host from an old host and just start paying double/triple the price without even knowing if I would receive back the returns as I expected? Backup and Restore in such a bulky numbers is something that I have never done before and hence I am stuck here trying to decide what to do. The price per month is also a considerable factor in my decision. All these web hosting companies say one common thing: It is customers responsibility to backup and restore data and they are not liable for any loss. So no matter what hosting company that I would like to go with, they ask me to take backup via FTP so that I can restore them whenever I want (& it seems to be safer to have the files locally with me). Some are providing tools for backup and some are not and I am not sure how much their backup tools can be trusted considering the disclaimers they have. I have never backed-up and restored 50,000 files from one web host to another, so please, all you experienced people out there, leave your comments and let me know your suggestions so that I can decide. I have spent 2 days fighting with myself trying to decide what to do and finally concluded that this is a double-edged sword and I can't arrive at a satisfactory final decision without involving others suggestions. I believe that someone must be out there who may have had such troublesome decision to make. So all your suggestions to help me make my decision are appreciated. Thank you all.

  • How do I extend the classpath used for 'grails run-app'

    - by Eric
    I have the following in my Config.groovy file: grails.config.locations = [ "classpath:env.groovy" ] Now, where exactly am I supposed to place "env.groovy" such that it is available on the CLASSPATH during grails run-app? The documentation here is sorely lacking. I am able to get it to work on the pure commandline by placing "env.groovy" in $APP_HOME/etc and then running: $ grails -classpath ./etc run-app This seems a little hackish, but I can live with it... However, I am unable to get any such configuration working when I launch run-app using the Grails eclipse plugin (STS): Unable to load specified config location classpath:env.groovy : class path resource [env.groovy] cannot be opened because it does not exist I've seen related posts here, here, here, and here but the answers have been unfulfilling. I am looking for a CLASSPATH-based solution that will work with 'run-app' in development mode (both commandline and from eclipse). I know how to set up the CLASSPATH for my deployment servlet container, so that is not an issue.

  • CURL issue in PHP while getting location list

    - by Ajay
    I am retrieving the nearest locations available from a given address (Longitude/Latitude) from geolocation website. It works fine, but for some places it gives junk characters in the name. Moreover, in browser I am getting different characters compared to my PHP CURL functionality. Here is the URL http://www.geoplugin.net/extras/nearby.gp?lat=17.7374669&long=83.3214858&limit=5&radius=50&format=php One of the location is "Sitampeta" in original location name, but in browser I am getting "Sitammapeta" where as in CURL function I am getting "Sītammapeta". Please tell me why this difference. I wrote a function to convert browser output to original which works fine. function convert ($old) { $n=""; for ($i=0; $i<strlen($old); $i++) { $n .= chr(ord(substr($old,$i,1))); } return $n; } But I dont understand how I convert the CURL output to original name.

  • Flash Builder 4 debug issue

    - by Tempname
    I am trying to debug an application in Flash Builder 4. The application I am working makes use of php session variables to ensure that the user is logged in. When not debugging, after logging in I can simply path to the container html file and everything works fine. However, when I am debugging a new IE window is launched but for some odd reason the previously logged in php session does not exist for this window. Is this an issue with IE?

  • How do I tell the difference between a success that is preceded by a momentary failure and failure?

    - by user128807
    When I'm trying out a new technology, I often fail. Sometimes I succeed, sometimes I continue to fail. So, in the first few moments after I try a new technology and experience failure, I cannot tell if I am on the path to success and have just experienced a momentary failure or if I am going to fail. I am wondering if anyone has a way to tell the difference between these two scenarios.

  • firefox render order problem with div tag

    - by flavour404
    I have a div tag which I populate dynamically. The problem is that in Firefox when i do a test for size(height) I seem to need to run it twice in order to get the correct size. This is the code: alert("h = " + h + " height:" + document.getElementById("thumbDiv").clientHeight); Ignore 'h' for the time being, what I am curious to know is what is the correct way to get the div tags height in firefox. In ie I use offsetHeight which works for my purposes perfectly. The other thing is the render order in firefox. I populate the div and then query the height with .clientHeight and I get 102, which is I am assuming the empty height of the tag as I have set no height via style, if I press the button again I then get the height of the div with the enlcosed html page which I am pushing into the div. Its odd, and slightly annoying. I am trying to determine if there is enough room in the browser to display the div contents in their entireity, if not then I am disabling certain features otherwise I get into an infinite scroll problem... Thanks, R. Thanks R.

  • prettyphoto and nivoslider

    - by Gabriel Ciprian Magda
    I have added the nivoslider and prettyphoto lightbox to a page. What I am trying to do: when you click one of the nivoslider images, prettyphoto should load a video. Everything works ok, except that whenever the nivo slider is sliding the images, the video in prettyphoto lightbox is reloading. How can I prevent the video from reloading once the sliding images are changing? I am not a javascript nija but I am guessing it can be done with changepicturecallback: function(){} from prettyphoto...

  • Stored procedures vs. parameter binding

    - by Gagan
    I am using SQL server and ODBC in visual c++ for writing to the database. Currently i am using parameter binding in SQL queries ( as i fill the database with only 5 - 6 queries and same is true for retrieving data). I dont know much about stored procedures and I am wondering how much if any performance increase stored procedures have over parameter binding as in parameter binding we prepare the query only once and just execute it later in the program for diferent set of values of variables.

  • Standardizing camera input in OpenCV? (Contrast/Saturation/Brightness etc..)

    - by karpathy
    I am building an application using OpenCV that uses the webcam and runs some vision algorithms. I would like to make this application available on the internet after I am done, but I am concerned about the vast differences in camera settings on every computer, and I am worried that the algorithm may break if the settings are too different from mine. Is there any way, after capturing the frame, to post process it and make sure that the contrast is X, brightness is Y, and saturation is Z? I think the Camera settings themselves can not be changed from code directly using the current OpenCV Python bindings. Would anyone be able to tell me about how I could calculate some of these parameters from the image and adjust them appropriately using OpenCV?

  • regressions with many nested categorical covariates

    - by eric
    I have a few hundred thousand measurements where the dependent variable is a probability, and would like to use logistic regression. However, the covariates I have are all categorical, and worse, are all nested. By this I mean that if a certain measurement has "city - Phoenix" then obviously it is certain to have "state - Arizona" and "country - U.S." I have four such factors - the most granular has some 20k levels, but if need be I could do without that one, I think. I also have a few non-nested categorical covariates (only four or so, with maybe three different levels each). What I am most interested in is prediction - given a new observation in some city, I would like to know the relevant probability/dependent variable. I am not interested as much in the related inferential machinery - standard deviations, etc - at least as of now. I am hoping I can afford to be sloppy. However, I would love to have that information unless it requires methods that are more computationally expensive. Does anyone have any advice on how to attack this? I have looked into mixed effects, but am not sure it is what I am looking for.

  • Python and database

    - by axl456
    hello.. Am working on a personal project, where i need to manipulate values in a database-like format.. Up until now, am using dictionaries, tuples, and list to store and consult those values. Am thinking about starting to use SQL to manipulate those values, but I dont know if its worth the effort, because I dont know anything about SQL, and I dont want to use something that wont bring me any benefits (if I can do it in a simpler way, i dont want to complicate things) if am only storing and consulting values, what would be the benefit of using SQL? PS: the numbers of row goes between 3 and 100 and the number of columns is around 10 (some may have 5 some may have 10 etc)

  • Using memory mapping in C for reading binary

    - by user1320912
    I am trying to read data from a binary file and process it.It is a very large file so I thought I would use memory mapping. I am trying to use memory mapping so I can read the file byte by byte. I am getting a few compiler errors while doing this. I am doing this on a linux platform #include <unistd.h> #include <sys/types.h> #include <sys/mman.h> int fd; char *data; fd = open("data.bin", O_RDONLY); pagesize = 4000; data = mmap((caddr_t)0, pagesize, PROT_READ, MAP_SHARED, fd, pagesize); The errors i get are : caddr not initialized, R_RDONLY not initialized, mmap has too few arguments. Could someone help me out ?
