  • Linux signals with extra information parameter

    - by Tester
    I was to have some extra information in the callback to sa_sigaction handler, it does not seems possible. So I was wondering if you could suggest me alternatives. Basic requirements: Function A raises an signal/event with a pointer to a struct Handler function tackles the event. The handler function would only be called on an event and a loop to wait for the event, as in select() , is undesirable. TIA

  • jQuery .ajax doesn't load Google Adsense

    - by Sahas Katta
    Hey Everyone, Just ran into an odd issue. I have a simple WP loop and instead of regular NEXT/BACK pages, I use a jQuery powered $.ajax get to append the following page to the current page. It works perfectly. However, I choose to insert a Google Adsense unit every 5th story. Unfortunately, the Adsense unit that is brought in with a second, third, or etc page load don't render. Here's my loop: 10 stories per page, Adsense after the 4th one. <?php $count = 0; ?> <?php if ( have_posts() ) : ?> <?php while ( have_posts() ) : the_post(); ?> <?php $count++; ?> <div class="card"> <div class="title"> <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><span><?php the_title(); ?></span></a> </div> </div> <?php if ($count == 4) : ?> <div class="card"> <!-- ADSENSE CODE HERE (Straight from Google Adsense Panel, no tweaks.) --> </div> <?php endif; ?> As for my jQuery script, here's how that looks: $.ajax({ url: nextPageLink, type: 'GET', success: function(data) { $(data).find('#reviews .card').appendTo('#reviews'); }, error: function(xhr, status, error) { $('.loadination').addClass('hidden'); } }); Keep in mind, I just simplified my code to give you guys an example. The code above was just the essentials. All the loading stuff works perfectly. Images, text, links, etc all load just fine. However, the Google Adsense unit doesn't. Any help would be appreciated. Thanks and Happy Holidays!

  • How can I find the number of highlighted chunks of text in an MS Word Document

    - by Majid
    Hi all, I am writing a macro in MS Word which should find all highlighted text in a document and perform some action on each. I am planning a loop to do the search and manipulation part and have no problem with this part of the code. But I don't know how to find how many iterations I'm going to need. Is there a vay to determine the number of highlights in VBA? Many thanks in advance.

  • [^.] causing headache in RewriteRule

    - by Ollie2893
    I am struggling with a very basic regex problem in my .htaccess file that I hope someone may be able to shed some light on. The basic premise is that I would like to teach Apache to switch any .html extension into a .var extension. I had thought that the rule would be positively trivial: RewriteRule ^([^.]+)\.html$ $1.var But the [^.] part simply doesn't work. Bizarrely, it works like so RewriteRule ^([^A-Z]+)\.html$ $1.var I do not understand why this latter rule works. Assume I am looking for a file called "index.html" then $1 should match to "index." and the ".html" bit should actually fail to match. To widen the scope of the question slightly, I am actually racking my brain on how to implement a multi-lingual site. I don't like Apache's MultiView option because it forces upon me a flat directory structure with file extensions that aren't recognizable to many development tools. I could go the .var type-map route but am finding that the default config for Apache doesn't support this all that well either (hence my excursions into regex land). So while I am using mod_rewrite, I am thinking that I might go the whole hog: whenever a request for a name.html file is received and this file does not exist, check whether there exists a XX/name.html file instead, where "XX" is the language code according to the user's preferences. This would give me a neater directory structure, though it does perhaps not perform as well as the .var approach in a situation where the language preference of the user's browser is not supported in by my site (in which situation .var would substitute EN or similar). Any thoughts? Thanks.

  • ListView exception for Images + Text

    - by drozzy
    I am trying to create a simple Icon+Text ListView but it does not work. I am using 2.1 Android SDK. My main class is very small slightly modified from the tutorial: public class Stuffs extends ListActivity { static final String[] COUNTRIES = new String[] {"A", "B","C"}; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, R.id.title, COUNTRIES)); } } and my list_item.xml file is this: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation = "horizontal"> <ImageView android:id = "@+id/icon" android:src="@drawable/icon" /> <TextView android:id = "@+id/title" android:padding="10dp" android:textSize="16sp" > </TextView> </LinearLayout> I have also created a "drawable" directory in my res directory and copied a "icon.png" into it. But any time I try to run this the application hangs up unexpected in my android emulator. Am I missing something?

  • WPF/C#: Images rotating from a listview?

    - by eibhrum
    I just want ask for your comments/suggestions on how to create a customized listview (if that's a good implementation) in WPF that displays images coming from a table from a database (more like a playlist) that rotates similar to a film (moving horizontally - on loop) Any ideas?

  • Dojo treemodel- adding large number of items

    - by Ashley
    I am trying to add a large number of items (100+) to my tree via ForestStoreModel by calling newItem in a loop. This seems to be quite slow and locks up the browser. Is there any way I can do something similar to grid's beginUpdate & endUpdate? I want to basically 'turn off' my tree, add 100 items in a batch, then 'turn on' my tree. Any ideas? Thanks!

  • Configuring visual subversion to exclude

    - by douglasrahn
    I have been searching for any documentation on how to exclude files for visual svn but have not found any. All the documentation I find seems to not match my file structure or I am missing some files/directories referenced. For example the only file I find with configuration items in it seems to be completely commented out and missing the miscellaneous section as well as any auto properties enable - etc... Ultimately I need to exclude some files so that my development can continue without SVN errors. I am constantly receiving errors for pbuser and other project files and would like to make sure this is not causing some of my other headaches. Here is information I would love to use but cant as it doesnt match: How to “fix” Subversion in XCode 3 Posted on December 10, 2008 by Rodney Aiglstorfer in Xcode If you don’t take the necessary steps to prepare for subversion, you will run into problems using it in XCode. This is because XCode produces files that “confuse” Subversion because it either thinks they are text files when they are really binary files or the reverse. To overcome these limitations, you need to make some simple changes to the subversion configuration file in your user home directory. Here are some steps you can follow to ensure that you will be able to use Subversion within XCode without any issues. Step 1. Open the subversion configuration file ~/.subversion/config NOTE: If the “.subversion” directory doesn’t exist yet then run this command which fails but will create the necessary files to get you started: svn status Step 2. Enable “global-ignores” and add new things to ignore Find the line that contains the text “global-ignores” and append the following text: build *~.nib *.so *.pbxuser *.mode* *.perspective* What I am looking for really is how to exclude the files I know I need to for Visual subversion - it shouldnt be different really from regular svn as it claims to use the same product just places a gui on it.

  • How can I check if an object has a specific method?

    - by Ghommey
    I want to use a method of an object. Like $myObject->helloWorld(). However there are a couple of methods so I loop through an array of method names and call the method like this: my $methodName ="helloWorld"; $myObject->$methodNames; This works quite nice but some objects don't have all methods. How can I tell whether $myObject has a method called helloWorld or not?

  • What happens inside the try block?

    - by dontWatchMyProfile
    Example: @try { // 1) do bad stuff that can throw an exception... // 2) do some more stuff // 3) ...and more... } @catch (NSException *e) { NSLog(@"Error: %@: %@", [e name], [e reason]); } If 1) throws an exception, is the block immediately canceled like a return in a function or a break in a loop? Or will 2) and 3) be processed no matter what happens in 1)?

  • hash fragments and collisions cont.

    - by Mark
    For this application I've mine I feel like I can get away with a 40 bit hash key, which seems awfully low, but see if you can confirm my reasoning (I want a small key because I want a small filename and the key will be converted to a filename): (Note: only accidental collisions a concern - no security issues.) A key point here is that the population in question is divided into groups, and a collision is only relevant if it occurs within the same group. A "group" is a directory on a user's system (the contents of files are hashed and a collision is only relevant if it occurs for files within the same directory). So with speculating roughly 100,000 potential users, say 2^17, that corresponds to 2^18 "groups" assuming 2 directories per user on average. So with a 40 bit key I can expect 2^(20+9) files created (among all users) before a collision occurs for some user somewhere. (Or IOW 2^((40+18)/2), due to the "birthday effect".) That's an average 4096 unique files created per user, for 2^17 users, before a single collision occurs for some user somewhere. And then that long again before another collision occurs somewhere (right?)

  • ASP.NET MVC model state as text

    - by David Moorhouse
    Is there an easy way to get a summary string of the errors that have been added to a controller's modelstate? I'm looking to return this in an Ajax method and want the validation errors etc to be returned to the client (i.e. the view does not exist for this method call). Or do I have to loop through the modelstate and look at each object and extract the error text manually?

  • Can I do a reduce on a list comprehension into two lists, based on two values?

    - by pdknsk
    I've got the following code. sum_review = reduce(add,[book['rw'] for book in books]) sum_rating = reduce(add,[book['rg'] for book in books]) items = len(books) avg_review = sum_review/items avg_rating = sum_rating/items What I'd like is this. sum_review,sum_rating = reduce(add,([book['rw'],[book['rg']) for book in books]) items = len(books) avg_review = sum_review/items avg_rating = sum_rating/items Obviously this doesn't work. How can I solve this redundancy, without a regular loop?

  • Where to create/keep secret files for license information/trials on Windows/Mac OS X/Linux?

    - by BastiBense
    I'm writing a commercial product which uses a simple registration mechanism and allows the user to use the application for a demo period before purchasing. My application must somewhere store the registration information (if entered) and/or the date of the first launch to calculate if the user is still within the demo/trail period. While I'm pretty much finished with the registration mechanism itself, I now have to find a good way to store the registration information on the user's disk. The most obvious idea would be to store the trial period in the preferences file, but since user tend to delete/tinker with those from time to time, it might be a good idea to keep the registration information in a separate, more hidden file. So here's my question: What is the best place/strategy to keep and create such hidden files on Windows, Mac OS X and Linux? Here is what came to my mind so far: Linux/Mac OS X Most Unix-like systems are rather locked down when it comes to places a user can write files to. In most cases this is only the /tmp directory and the user's home directory. I guess the easiest here is probably to create a file with a dot-prefix to make it less visible, then give it a name that won't make it obvious that it's associated with my application. Windows Probably much like Linux/Mac OS X - more recent Windows versions become more restrictive when it comes to file system permissions. Anyway, I'd like to hear your ideas and thoughs. Even better if you have already implemented something similar in the past. Thanks! Update For me the places for such files is more relevant than the discussion of the question if this way for copy protection is good or bad.

  • Scalable way to store files on server (PHP)?

    - by Nathaniel Bennett
    I'm creating my first web application - a really simplistic online text editor. What I need to do is find the best way to store text based files - a lot of them. These text files can be past 10,000 words in size (text words not computer words.) in essence I want the text documents to be limitless in size. I was thinking about storing the text files in my MySQL database - but thought there was a better way. Instead I'm planing on storing the text files in XML based format in a directory on my server. The rows in the database define the name of the xml based text file and the user who created the text along with basic metadata. An ID is generated using a V4 GUID generator , which gives the text an id and stores the text in the "/store" directory on my server. The text definitions in my server contain this id, and the android app I'm developing gets the contents of the text file by retrieving the text definition and then downloading the text to the local device using the GUID in the text definition. I just think this is a botch job? how can I improve this system? There has been cases of GUID colliding. I don't want this to happen. A "slim" possibility isn't good enough - I need to make sure there is absolutely no chance in a GUID collision. I was planning on checking the database for texts that have the same id before storing the text with a particular id - I however believe with over 20,000 pieces of text in my database this would take an long time and produce unneeded stress on the server. How can I make GUID safe? What happens when a GUID collides? The server backend is going to be written in PHP.

    Is it possible to do mass updates on a given entity in Core Data? Given an Person entity for example, can I do something like this: Person.update(@"set displayOrder = displayOrder + 1 where displayOrder > 5") Or is my only option to fetch all the entities needed and then loop through and update them individually???

  • Which is more efficient in mysql, a big join or multiple queries of single table?

    - by Tom Greenpoint
    I have a mysql database like this Post – 500,000 rows (Postid,Userid) Photo – 200,000 rows (Photoid,Postid) About 50,000 posts have photos, average 4 each, most posts do not have photos. I need to get a feed of all posts with photos for a userid, average 50 posts each. Which approach would be more efficient? 1: Big Join select * from post left join photo on post.postid=photo.postid where post.userid=123 2: Multiple queries select * from post where userid=123 while (loop through rows) { select * from photo where postid=row[postid] }

  • Get spiral index from location

    - by ricick
    I'm using Alberto Santini's solution to this question to get a spiral grid reference based on an items index Algorithm for iterating over an outward spiral on a discrete 2D grid from the origin It's not the accepted solution, but it's the best for my needs as it avoids using a loop. It's working well, but what I want now is to do the inverse. Based on a known x and y coordinate return the index of a location. This is as a precursor to returning the items surrounding a given location.

  • Ordered hash in JavaScript

    JavaScript objects have no order stored for properties (according to the spec). Firefox seems preserve the order of definition of properties when using a for...in loop. Is this behaviour something that I can rely on? If not is there a piece of JavaScript code somewhere that implements an ordered hash type?
