• WordPress query posts into two Divs

  - by Cameron

  I want to display my wordpress posts in a category in two divs. So for example: <div id="left"> POST 1 POST 3 POST 5 POST 7 </div> <div id="right" POST 2 POST 4 POST 6 POST 8 </div> So want I need to do is tell the query_posts to somehow start spitting out the first 4 posts oddly and then evenly for each div. I don't want to have two seperate WP_Queries as this is a category.php file and needs to have the default loop. Not quite sure how to do this. Any help much appreciated.

• Resources on wordpress theme-development

  - by Espenhh

  What are the best resources for Wordpress theme-development? I am currently in the phase of starting my own blog, and don't want to use one of the many free themes. I already have a theme for my website, so I want to read about best-practices. Any advice on how to get started would be very welcome :) I have now created my theme (wohoo!), and thought I should summarize the best resources I found. Lets see.. Resources: ThemeTation's three-part guide to create a wordpress-theme from scratch Nettuts.com's guide: How to Create a Wordpress Theme from Scratch (And Part 2) Didn't actually use this, it's a quite new article, but anyway - it's great. It will get a follow-up in the next few days too.. Wordpress.org's own guide on templates Definatly a must-read for everyone new to wordpress-designing.. "The loop" Essential knowledge, also a must-read Directory of all the template tags Used by wordpress to actually output blog-content.. Inspiration: Smashing Magazine's lists: first, one more, yet another one Wordpress.org's theme-directory

• keeping xmphp bot always online

  - by Gunjan

  I created a simple xmpp bot in PHP which connects to google talk server. I basically modified the cli_longrun example. When I run the script in browser the bot comes online and stays online for a while even after I close the tab on which the script was running (as it is just an infinite loop listening for events on the stream). But after a while the bot becomes offline. The question is how do I keep the bot always online. One way I can think of is to run a cron that would disconnect the earlier one and start a new session. But is there a better approch?

• different overlay specification in different beamer modes?

  - by Matthew Leingang

  I have a beamer frame with about 150 slides on it. I want article and handout mode to only show frame 92. Reading section 8.6.2 of the beamer manual it seems like I should be able to do something like \begin{frame}<handout:92> ... \end{frame} but that seems to have no effect--all 150 slides are set in handout mode, overlaying (making the result unreadable). I have gotten the effect I want by taking all commands within the frame that have an overlay specification and adding "| handout:0" to make them not appear in handout mode. Annoying, but works. But for my 150-slide frame the different slides are generated by a PGF \foreach loop so I can't code slide 92 differently from the rest. But can I do this at the frame's overlay specification?

• Win32 call order

  - by DD

  Hi all, I have two windows that I send scripted input to. The procedure goes as this BringWindowToTop( window1 ); i = Build input structures( window1 ); SendInput(i); BringWindowToTop( window2 ); i = Build input structures( window2 ); SendInput(i); I was having trouble with inputs not being sent and the correct time. I put delays after each call and saw that input from the first SendInput() was processed after window2 is brought to top. Same thing at the end of the loop as well. Are SendInput calls buffered? If so, how can I make sure of a serial execution of this code? Thanks

• Multiple return points in scala closure/anonymous function

  - by Debilski

  As far as I understand it, there is no way in Scala to have multiple return points in an anonymous function, i.e. someList.map((i) => { if (i%2 == 0) return i // the early return allows me to avoid the else clause doMoreStuffAndReturnSomething(i) }) raises an error: return outside method definition. (And if it weren’t to raise that, the code would not work as I’d like it to work.) One workaround I could thing of would be the following someList.map({ def f(i: Int):Int = { if (i%2 == 0) return i doMoreStuffAndReturnSomething(i) } f }) however, I’d like to know if there is another ‘accepted’ way of doing this. Maybe a possibility to go without a name for the inner function? (A use case would be to emulate some valued continue construct inside the loop.)

• JSTL - Format date

  - by John Manak

  Hi! I have a loop that goes through all the news items we have on our site. One of the fields is date ${newsitem.value['Date']}, given in millliseconds. I'd like to display this date in month/day/year format on the webpage. I thought JSTL format tag, <fmt:formatDate>, would help, but I haven't succeeded. Do you know how to do it? <cms:contentaccess var="newsitem" /> <h2><c:out value="${newsitem.value['Title']}" /></h2> // display date here <c:out value="${newsitem.value['Text']}" escapeXml="false" />

• WindowsForms difference to simple Console App

  - by daemonfire300

  I currently started to "port" my console projects to WinForms, but it seems I am badly failing doing that. I am simply used to a console structure: I got my classes interacting with each other depending on the input coming from the console. A simple flow: Input -> ProcessInput -> Execute -> Output -> wait for input Now I got this big Form1.cs (etc.) and the "Application.Run(Form1);" But I really got no clue how my classes can interact with the form and create a flow like I described above. I mean, I just have these "...._Click(object sender....)" for each "item" inside the form. Now I do not know where to place / start my flow / loop, and how my classes can interact with the form.

• Does a Collection<T> wrap an IList<T> or enumerate over the IList<T>?

  - by Brian Triplett

  If I am exposing a internal member via a Collection property via: public Collection<T> Entries { get { return new Collection<T>(this.fieldImplimentingIList<T>); } } When this property is called what happens? For example what happens when the following lines of code are called: T test = instanceOfAbove.Entries[i]; instanceOfAbove[i] = valueOfTypeT; It's clear that each time this property is called a new reference type is created but what acctually happens? Does it simply wrap the IList<T> underneath, does it enumerate over the IList<T> and to create a new Collection<T> instance? I'm concerned about performance if this property is used in a for loop.

• GUI freezing after datagridviews have been updated using backgroundworkers

  - by Jhon

  I have made an application which runs three backgroundworkers simultaneously. It basically updates three datagridviews, which it is doing spot on. My problem is if I press maximizebox button or anywhere in any of the datagridview the program hangs for quite a long time. I am able to use the horizontal scroll but not vertical scrolls. I have tried Backgroundworker_runworkercompleted and it fires as required after threads have updated their respective datagridviews. Is it a normal behaviour or am i doing something wrong any suggestions would be helpful. P.S: I have run the whole program using step method and their is no infinite loop in the code. Thanks in advance Jhon

• C#, string replace russian to english

  - by Fabio Beoni

  Hello, I have a strange problem replacing chars in string... I read a .txt file containing russian text, and starting from a list of letters russian to english (ru=en), I loop the list and I WOULD like to replace russian characters with english characters. The problem is: I can see in the debug the right reading of the russian and the right reading of the english, but using myWord = myWord.Replace(ruChar, enChar), the string is not replaced. My txt file is a UTF-8 encoding. Any suggestions?? Thank you to all...

• Easiest way to pass a javascript array or its values to a servlet and convert to a HashMap

  - by Ankur

  I have a Javascript array. I want to pass it's data to a servlet using the ajax() method of jQuery. What is the easiest way to do this. The index values i.e. the i in array[i] are not in order, they are numbers that have meaning themselves, hence I cannot simply loop through and create a GET queryString, or so I believe. Maybe I should be converting the JavaScript array to a JSON Object and sending that to the server ?? I am stumped on this one.

• Problem displaying Vertex Buffer Object (OpenGL and Obj-C)

  - by seaworthy

  Hey, I am having a problem displaying or loading a buffer with an array of vertices. I know that array works fine because I am able to render it using a loop and a glVertex command. I can't figure out what's wrong. Your insight is highly appreciated. GLuint vboId; glGenBuffers( 1, &vboId ); glBindBuffer( GL_ARRAY_BUFFER, vboId); glBufferData( GL_ARRAY_BUFFER, count*sizeof( GLfloat ),array,GL_STATIC_DRAW_ARB ); glBindBuffer( GL_ARRAY_BUFFER, 0 ); printf("%d\n",count); glEnableClientState( GL_VERTEX_ARRAY ); glBindBuffer( GL_ARRAY_BUFFER, vboId ); glVertexPointer( 3, GL_FLOAT, 0, 0 ); glDisableClientState( GL_VERTEX_ARRAY ); printf("vboId: [%hd]",vboId); glDeleteBuffers(1, &vboId); Help?

• What is the right approach when using STL container for median calculation?

  - by sharkin

  Let's say I need to retrieve the median from a sequence of 1000000 random numeric values. If using anything but STL::list, I have no (built-in) way to sort sequence for median calculation. If using STL::list, I can't randomly access values to retrieve middle (median) of sorted sequence. Is it better to implement sorting myself and go with e.g. STL::vector, or is it better to use STL::list and use STL::list::iterator to for-loop-walk to the median value? The latter seems less overheadish, but also feels more ugly.. Or are there more and better alternatives for me?

• Can I use array_push on a SESSION array in php?

  - by zeckdude

  I have an array that I want on multiple pages, so I made it a SESSION array. I want to add a series of names and then on another page, I want to be able to use a foreach loop to echo out all the names in that array. This is the session: $_SESSION['names'] I want to add a series of names to that array using array_push like this: array_push($_SESSION['names'],$name); I am getting this error: array_push() [function.array-push]: First argument should be an array Can I use array_push to put multiple values into that array? Or perhaps there is a better, more efficient way of doing what I am trying to achieve?

• How's my pygame code?

  - by Isaiah

  I'm still getting the hang of lots of things and thought I should post some code I made with pygame and get some feedback^^. I posted code here: http://urlvars.com/code/snippet/39272/my-bouncing-program http://urlvars.com/code/snippet/39273/my-bouncing-program-classes There's tome things that I implemented that I'm not using yet I just realized like a timer at the bottom of the main while loop. If my code isn't readable, I'm sorry, I'm self taught and this is the first code I've ever posted anywhere. By the way I made some variables that take the screensize and half it to find a point to spit out the squares, but when I try to use it, it makes a weird effect :/ Try switching the list i have in the newbyte() function with the halfScreen variable and see it freak out o.O thank you

• Is looping through the entityreference the correct way?

  - by Jova

  I want to get all users that have a specific role to a list of usernames. Is using .Include to include all the users, and going through the UsersReference the best way to loop through all the users that are associated with the role? I noticed I could not do a foreach(User user in role.Users) but UsersReference seem to work, but is that how it's supposed to be done? Going through the reference? using (var context = new MyEntities()) { List<string> users = new List<string>(); Role role = (from r in context.Roles.Include("Users") where r.RoleName == roleName select r).FirstOrDefault(); foreach (User user in role.UsersReference) users.Add(user.UserName); return users.ToArray(); }

• How do I echo the number of items in an array?

  - by Joel

  A total newbie question I know. I'm sing Zend framework, and sending an array from the controller: $this->view->googleArray = $viewFeedArray; In the view, I have a foreach loop that is populating a table with the array contents. <?php foreach($this->googleArray as $row) { ?> <tr> <td><?php echo $row['when']; ?></td> ... ... </tr> <?php } ?> It all works fine. At the top of the table, I want to list the number of items in the array. Something like (which doesn't work): <?php echo $this->googleArray->totalResults; ?> event(s) found How would I do that? Thanks!

• How do I stall until a SharePoint List Item is Deleted with SPLongOperation?

  - by ccomet

  I have a workflow, which creates a task and deletes it after the task is edited and its useful information acquired. I created a custom edit form for the task, so I have an SPLongOperation that I can use to stall the page. This is necessary, because if I don't stall the page in some fashion, the person will see the task in the task list for the minute moment before the workflow gets to delete the task, and that is bad. So some code to stall the page until the task is fully deleted is necessary. I have currently implemented a solution for this, but I am unsatisfied with the approach. It basically is summed up to a while loop that calls SPList.GetItemById until it throws an error. Delibrately attempting to cause an error doesn't sit well with me, but I cannot think of a faster method for checking this. I'm looking for alternatives that would preferably work faster if not as fast, and preferably without relying on catching exceptions. Thank you in advance!

• Best way to access database from android

  - by Brandon Delany

  I am working on a Android app and I have a dilemma. I have a list of Objects. I have to update each of these objects with a database. I have 2 methods: Method 1: I can loop through the Objects. For each object I can connect to the server, update it, and then move on to the next Object, and so forth. Method 2: I can store the Objects in a list, send the whole list to the server, update it on the server side, then return a list of updated objects. My questions are: Which method is faster? Which method is easier on the phone's battery? By the way, Method 1 is easier for me to code :). Thank you.

• In what order does evaluation of post-increment operator happen?

  - by sum1stolemyname

  Given std::vector<CMyClass> objects; CMyClass list[MAX_OBJECT_COUNT]; Is it wise to do this? for(unsigned int i = 0; i < objects.size(); list[i] = objects.at(i++)); Or should I expand my loop to this? for(unsigned int i = 0; i < objects.size(); i++) { list[i] = objects.at(i); }

• Image processing in a multhithreaded mode using Java

  - by jadaaih

  Hi Folks, I am supposed to process images in a multithreaded mode using Java. I may having varying number of images where as my number of threads are fixed. I have to process all the images using the fixed set of threads. I am just stuck up on how to do it, I had a look ThreadExecutor and BlockingQueues etc...I am still not clear. What I am doing is, - Get the images and add them in a LinkedBlockingQueue which has runnable code of the image processor. - Create a threadpoolexecutor for which one of the arguements is the LinkedBlockingQueue earlier. - Iterate through a for loop till the queue size and do a threadpoolexecutor.execute(linkedblockingqueue.poll). - all i see is it processes only 100 images which is the minimum thread size passed in LinkedBlockingQueue size. I see I am seriously wrong in my understanding somewhere, how do I process all the images in sets of 100(threads) until they are all done? Any examples or psuedocodes would be highly helpful Thanks!

• Using Unix Process Controll Methods in Ruby

  - by John F. Miller

  Ryan Tomayko touched off quite a fire storm with this post about using Unix process control commands. We should be doing more of this. A lot more of this. I'm talking about fork(2), execve(2), pipe(2), socketpair(2), select(2), kill(2), sigaction(2), and so on and so forth. These are our friends. They want so badly just to help us. I have a bit of code (a delayed_job clone for DataMapper that I think would fit right in with this, but I'm not clear on how to take advantage of the listed commands. Any Ideas on how to improve this code? def start say "*** Starting job worker #{@name}" t = Thread.new do loop do delay = Update.work_off(self) break if $exit sleep delay break if $exit end clear_locks end trap('TERM') { terminate_with t } trap('INT') { terminate_with t } trap('USR1') do say "Wakeup Signal Caught" t.run end end

• What is the result of X(X,X)? [closed]

  - by Sorush Rabiee

  A friend who studies pure mathematics ask me to think about the following problem. Suppose that there is an algorithm named X that has 2 inputs: A and a_1...a_n, where 'A' stands for an arbitary algorithm and 'a_1..a_n' are inputs of A. X receives A and its inputs and returns true if A with a_1..a_n could be terminated, and false if A with a_1..a_n inputs fall into an infinite loop (never ends). Like this: A(n): while(n<5): write "I'm immortal!" and the result of X(A,6) is true and X(A,2) is false. So what is the result of X(X,X)? Also, do you know who was the first to introduce this problem?

• Throw of a dice in Java

  - by Arkapravo

  The throw of a dice is a popular program in Java, public class Dice { /* This program simulates rolling a dice */ public static void main(String[] args) { int dice; // The number on the dice. dice = (int) (Math.random() * 6 + 1); System.out.println (dice); } } What I wish to do is make it repeat, 500 times. I have not been able to put this program into a loop of 500. I usually program in Python, thus I guess my Java has rusted ! Any help is most welcome !
