  • With ARC why use @properties anymore?

    - by trapper
    In non-ARC code retained properties handily take care of memory management for you using the self.property = syntax, so we were taught to use them for practically everything. But now with ARC this memory management is no longer an issue, so does the reason for using properties evaporate? is there still any good reason (obviously other than providing public access to instance variables) to use properties anymore?

  • will mmap use user cpu instead of whole sys cpu? (solaris)

    - by Daniel
    when use mmap to allocate some anonymous mem, we often set the start address as 0/null so mmap will figure out the starting address by itself. And to get the start address, it will work thought the whole virtual memory space to find a hole which could put the chuck of mem to be allocated. I guess this is calculated as user cpu instead of sys cpu. If the virtual memory is fragmented, then the time to find the starting address will use more user cpu, is my understanding correct

  • Accessing Element Count and Values Within a Hidden Div

    - by Tegan Snyder
    I'm having trouble grabbing the TR count in JQuery of a table that inside a DIV set to be hidden. Here is an example: <div id="questions" style="display: none;"> <table id="tbl_questions"> <thead> <tr> <th>Question</th> <th>Weight</th> </tr> </thead> <tbody> <tr id="q0"> <td id="td_question0">Some Question 0</td> <td id="td_wieght0">Some Weight 0</td> </tr> <tr id="q1"> <td id="td_question1">Some Question 1</td> <td id="td_wieght1">Some Weight 1</td> </tr> </tbody> </table> </div> Note the table is within the containing div. It's set to display: none. When I try to run this JQuery code it returns 0. var question_count = $("#tbl_questions> tr").size(); alert(question_count); Any ideas? I'm try to locate the count so I can then build an array of each question and weight in the table. Since the ID's provide me with an index this should be simple, but is the fact that it is contained in a hidden DIV going to be a problem just as the above question? Thanks, Tegan Snyder

  • Find out why Xcode has decided to link to a particular library

    - by andygeers
    I'm using the Unity 3D engine to build an iPhone app, and when I go to generate my Xcode project for compilation, it includes a few fairly large libraries: Mono.Security.dll.s, System.dll.s, System.Core.dll.s, etc. I don't know if this question is really an Xcode question or a Unity question, but I'm trying to figure out why each of those libraries is being linked - which functions / classes are being referenced - ideally so that I can rewrite my code to remove as many of the dependencies as possible. Does anybody know a way to find this information out?

  • Pre-load audio files at the client-side for later use

    - by awj
    I'm building an online test which implements audio (mp3) using the native audio player (i.e. non Flash-based). The test shows one question at a time and loads each subsequent question asynchronously. Some questions have an accompanying audio file, others don't, and the audio files can be several MB in size. So what I'm hoping to do is to preload the audio files client-side at the start of the test and then move these into place when the relevant question comes up. So far I've tried loading an audio file into a QuickTime player, then when that question comes up I use jQuery's clone(true) method to copy this into a part of the page which is displayed. However, when I do this the QuickTime player has to reload the audio file from source. Same is true for Windows Media Player. Does anyone have any suggestions as to how I can preload the audio client-side and then call it forward when needed?

  • Grading your programming ability?

    - by Farstucker
    I understand this is a subjective question and very likely could be closed, and although there is no right or wrong answer I do believe its a legitimate question. At what point do you no longer consider someone a beginner (ie knowledge of loops, encapsulation, instantiation), an intermediate (design patterns, reflection, delegates, interfaces) or an expert (architecture, multi-threadding). My rational for asking such a question is two-fold, first, when do I stop labeling my questions as beginner and during a job interview how should I categorize myself?

IdCategory : bigint (FK) How do I recursively count all Questions for a given Category (including questions in subcategories). I've tried it already based on several tutorials but still can't figure it out :(

  • Installing Mercurial on Windows Apache XAMPP Tutorial

    - by Tim Dellas
    After asking this question (http://stackoverflow.com/questions/2675764/xampp-mercurial-installation-on-windows-apache-hgwebdir-cgi-script-error) and reading though the whole internet including this question (http://stackoverflow.com/questions/644322/how-do-i-get-mercurials-hgwebdir-working-on-windows) and all its links for about 10 hours, I seem to not be able to find a solution. I begun with this tutorial http://mercurial.selenic.com/wiki/HgWebDirStepByStep ... and I really don't want to install ancient versions of Mercurial. I got my windows-apache to run Python scripts, CGI-Scripts, publish them in the wild, but hgwebdir just won't work. Question 1: Can someone please enrich his personal blog with a tutorial on how to install MERCURIAL on a WINDOWS XAMPP installation and make it visible to the world? I guarantee a lot of pageviews, as this is not a trivial problem. And this would sincerely help a lot of other people I guess. Question 2: For example, even after browsing half a day through everywhere, I just cannot find out, which version of python I need to pair with the freshest version of mercurial, and I get the "magic number is wrong"-error. This would be my question, if noone has time to make up a nice blogpost. Sorry for being a bit frustrated.

  • How to add Flex 4 spark List Item custom properties

    - by maik3l
    I'm trying to make a simple flash application providing interface for taking tests as a high school assignment. One of the requirements is to use an XML file as data source.Now, having a List component bound to the XML file with questions consisting of data such as question body, question type (ie. single choice, multiple choice, open, image etc.) and possible answers (where applicable), I was wondering if I could add some additional data (and what is the best possible way to do so) to each question upon its transfer to the List component. I am trying to achieve two main goals with this: firstly, to mark the questions to which an answer has already been given, like with such code in ItemRenderer class: <s:Label color="{data.color}" text="{data.label}"/> where data.color would be set whenever the user gives an answer to a question. Secondly, while at it, I thought of such possibility as a great way to store answers given to particular questions. In this case, the Class of the answer object would have been Object, since there has to be many type of questions (where the answer could also be a Bitmap for example). This is a question of both how to do it and if it seems a good idea at all (and if no, if there is a better way?), because I am quite new to the whole Flash Builder and Flex thing and I am not really accustomed to all the possibilities and best practices. Thanks!

  • Load large images into Bitmap?

    - by GuyNoir
    I'm trying to make a basic application that displays an image from the camera, but I when I try to load the .jpg in from the sdcard with BitmapFactory.decodeFile, it returns null. It doesn't give an out of memory error which I find strange, but the exact same code works fine on smaller images. How does the generic gallery display huge pictures from the camera with so little memory?

  • How to access the private variables of a class in its subclass?

    - by giri
    This is a question I was asked in an interview: I have class A with private members and Class B extends A. I know private members of a class cannot be accessed, but the question is: I need to access private members of class A from class B, rather than create variables with the same value in class B. I hope I am clear with this question. Thanks.

  • Can folks that edit tags make sure they preserve the information that they would be editing away?

    - by vkraemer
    I have notice that some folks edit the tags associated with questions to make the tag more generic, like converting netbeans6.8-netbeans. I think this is a good thing. BUT, most users/askers do not include version info in the text of their question and some of them do pick the 'versioned' tag. That additional info is valuable at that point. Please read the question before you edit version info out of tags. If the version info is not in the question's text.... take another moment to edit the text of the question, so the info is immediately available to folks that are trying to answer questions.

  • Function allocation

    - by novice_coder
    Where are functions stored in a C++ program? For example int abc() { //where am I stored? } I know that we can take the address of a function, that means functions are stored somewhere in memory. But I have already read at many places that no memory allocation for functions takes place. I am confused. My question may seem vague to many of you but I can't help.

  • How to develop an english .com domain value rating algorithm?

    - by Tom
    I've been thinking about an algorithm that should rougly be able to guess the value of an english .com domain in most cases. For this to work I want to perform tests that consider the strengths and weaknesses of an english .com domain. A simple point based system is what I had in mind, where each domain property can be given a certain weight to factor it's importance in. I had these properties in mind: domain character length Eg. initially 20 points are added. If the domain has 4 or less characters, no points are substracted. For each extra character, one or more points are substracted on an exponential basis (the more characters, the higher the penalty). domain characters Eg. initially 20 points are added. If the domain is only alphabetic, no points are substracted. For each non-alhabetic character, X points are substracted (exponential increase again). domain name words Scans through a big offline english database, including non-formal speech, eg. words like "tweet" should be recognized. Question 1 : where can I get a modern list of english words for use in such application? Are these lists available for free? Are there lists like these with non-formal words? The more words are found per character, the more points are added. So, a domain with a lot of characters will still not get a lot of points. words hype-level I believe this is a tricky one, but this should be the cause to differentiate perfect but boring domains from perfect and interesting domains. For example, the following domain is probably not that valueable: www.peanutgalaxy.com The algorithm should identify that peanuts and galaxies are not very popular topics on the web. This is just an example. On the other side, a domain like www.shopdeals.com should ring a bell to the hype test, as shops and deals are quite popular on the web. My initial thought would be to see how often these keywords are references to on the web, preferably with some database. Question 2: is this logic flawed, or does this hype level test have merit? Question 3: are such "hype databases" available? Or is there anything else that could work offline? The problem with eg. a query to google is that it requires a lot of requests due to the many domains to be tested. domain name spelling mistakes Domains like "freemoneyz.com" etc. are generally (notice I am making a lot of assumptions in this post but that's necessary I believe) not valueable due to the spelling mistakes. Question 4: are there any offline APIs available to check for spelling mistakes, preferably in javascript or some database that I can use interact with myself. Or should a word list help here as well? use of consonants, vowels etc. A domain that is easy to pronounce (eg. Google) is usually much more valueable than one that is not (eg. Gkyld). Question 5: how does one test for such pronuncability? Do you check for consonants, vowels, etc.? What does a valueable domain have? Has there been any work in this field, where should I look? That is what I came up with, which leads me to my final two questions. Question 6: can you think of any more english .com domain strengths or weaknesses? Which? How would you implement these? Question 7: do you believe this idea has any merit or all, or am I too naive? Anything I should know, read or hear about? Suggestions/comments? Thanks!

  • Why does GC not clear the Dialog references?

    - by Pavel
    I have a dialog. Every time I create it and then dispose, it stays in memory. It seems to be a memory leak somewhere, but I can't figure it out. Do you have any ideas? See the screenshot of heap dump for more information. Thanks in advance. http://img441.imageshack.us/img441/5764/leak.png

  • Can I add elements to a Java GUI?

    - by Asj
    I want to know how I can make a java program where an unknown amount of objects can be added to a GUI depending on user input. I can program in objects one at a time within the program, but I haven't seen a more dynamic program. Can I do that with Java? If not, what can I do it with? For more information, here's a picture. http://i6.photobucket.com/albums/y223/Asj127/CapProjIdea.jpg There can be more than one question per question block, and each question can have it's own question block.

  • ASP.Net Typed Datasets life span

    - by JBeckton
    What happens to a dataset when your done using it. For example if I create and fill a dataset for a grid, when the user leaves that page or logs out I assume the dataset is still in memory? Does each user get their own instance of the dataset? In other words, if 2 users hit the same page that uses a grid are they each served their own instance of the dataset from server memory?
