  • why can't I call methods on a for-yield expression?

    - by 1984isnotamanual
    Say I have some scala code like this: // outputs 1, 4, 9, 16, 25, 36, 49, 64, 81, 100 println( squares ) def squares = { val s = for ( count <- 1 to 10 ) yield { count * count } s.mkString(", "); } Why do I have to use the temporary val s? I tried this: def squares = for ( count <- 1 to 10 ) yield { count * count }.mkString(", ") That fails to compile with this error message: error: value mkString is not a member of Int def squares = for ( count <- 1 to 10 ) yield { count * count }.mkString(", ") Shouldn't mkString be called on the collection returned by the for loop?

  • Firebird 2.1 + EXISTS = query bug?

    - by Atlas
    Using Delphi 2009 + Firebird 2.1.3. Database is ODS 11.1, default char set is UTF8. My prepared query is as follows: SELECT a.po_id, a.po_no FROM purchase_order a WHERE EXISTS (SELECT 1 FROM sales_order_item z1 JOIN purchase_order_item z2 ON z2.so_item_id = z1.so_item_id AND z2.po_id = a.po_id WHERE z1.so_id = :soid) ORDER BY a.po_no Now when I loop this say 1000 times because I have 1000 x so_id, the CPU usage get at 100% for FBSERVER.EXE Anyone encountered this problem?

  • 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!

  • Retrieve all records in a table with nHibernate

    - by brainimus
    I need to retrieve all the records in a table with nHibernate. If I had the key for all the records in the table I could loop and use nHibernate's Get method (this seems inefficient though) but I don't have the keys. I could also use FindAll but this requires criteria or a stored procedure. How can I get all the records from the table?

  • How can I split a list with multiple delimiters?

    - by Rob
    Basically, I want to enter text into a text area, and then use them. For example variable1:variable2@variable3 variable1:variable2@variable3 variable1:variable2@variable3 I know I could use explode to make each line into an array, and then use a foreach loop to use each line separately, but how would I separate the three variables to use?

  • Is this a good approach to dealing with tagging?

    - by Mel
    Can this code be optimized or re-factored? Is this an optimal approach to tagging? The following code is a callback in my posts model. It creates a record that associates a tag with a post in a QuestionsTags joiner table. When necessary, if a given tag does not already exist in the tags table, the function creates it, then uses its id to create the new record in the QuestionsTags table. The difficulty with this approach is the QuestionsTags table depends on data in the tags table which may or may not exist. The function assumes the following tables: tags(id, tagName), posts(tags) // Comma delimited list questionsTags(postId, tagId) The idea is to loop over a delimited list of tags submitted with a post and check to see if each tag already exists in the tags table If tag exists: Check to see if there's already a QuestionTag record for this post and this tag in the QuestionTags table. If yes, do nothing (the association already exists) If no, create a new QuestionTag record using the id of the existing tag and the postId If tag does not already exist: Create the new tag in the tags table Use its id to create a new QuestionsTags record Code /** * @hint Sets tags for a given question. **/ private function setTags() { // Loop over the comma and space delmited list of tags for (local.i = 1; local.i LTE ListLen(this.tags, ", "); local.i = (local.i + 1)) { // Check if the tag already exists in the database local.tag = model("tag").findOneByTagName(local.i); // If the tag exists, look for an existing association between the tag and the question in the QuestionTag table if (IsObject(local.tag)) { local.questionTag = model("questionTag").findOneByPostIdAndTagId(values="#this.postId#,#local.tag.id#"); // If no assciatione exists, create a new QuestionTag record using the tagId and the postId if (! IsObject(local.questionTag)) { local.newQuestionTag = model("questionTag").new(postId = this.id, tagId = local.tag.id); // Abort if the saving the new QuestionTag is unsuccesful if (! local.newQuestionTag.save()) { return false; } } } // If the tag does not exist create it else { local.newTag = model("tag").new(tagName = local.i, userId = this.ownerUserId); // Abort if the the new tag is not saved successfully if (! local.newTag.save()) { return false; } // Otherwise create a new association in the QuestionTags table using the id of the newly created tag and the postId local.newQuestionTag = model("questionTag").new(postId = this.id, tagId = local.newTag.id); // Abort if the new QuestionTag does not save correctly if (! local.newQuestionTag.save()) { return false; } } } } FYI: I'm using CFWheels in my application, which explains the ORM functions used.

  • Indexing through Android string resources

    - by gssi
    OK, I've got the code to allow me to index through the string resources. Now, how do I get the value of a specific resource item without knowing its name? Here's the index loop: Field[] fLst = R.string.class.getFields(); for(Field f : fLst){ Log.i(dbgTag, "Field Entry: R.string." + f.getName()); } Thanks for your efforts ...

  • Get last/newly added element in std::set

    - by Dave17
    can you get the last or newly added element in std::set? for example say if the loop runs to collect the elements to fill in the std::set. if on the first run the set was, [0] "A" [1] "B" [2] "D" and, on second run, the set becomes [0] "A" [1] "B" [2] "C" [3] "D" How would you check if 'C' is the new element that was added?

  • 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.

  • Unexpected output while using Microsoft Visual Studio 2008 (Express Edition) C++ Command Line Tool

    - by Sujith S Pillai
    One of my friends sent this code to me, saying it doesn't work as expected: #include<stdio.h> void main() { int a [10] ={23, 100, 20, 30, 25, 45, 40, 55, 43, 42}; int sizeOfInput = sizeof(a)/sizeof(int); int b, outer, inner, c; printf("Size is : %d \n", sizeOfInput); printf("Values before bubble sort are : \n"); for ( b = 0; b < sizeOfInput; b++) printf("%d\n", a[b]); printf("End of values before bubble sort... \n"); for ( outer = sizeOfInput; outer > 0; outer-- ) { for ( inner = 0 ; inner < outer ; inner++) { printf ( "Comparing positions: %d and %d\n",inner,inner+1); if ( a[inner] > a[inner + 1] ) { int tmp = a[inner]; a[inner] = a [inner+1]; a[inner+1] = tmp; } } printf ( "Bubble sort total array size after inner loop is %d :\n",sizeOfInput); printf ( "Bubble sort sizeOfInput after inner loop is %d :\n",sizeOfInput); } printf ( "Bubble sort total array size at the end is %d :\n",sizeOfInput); for ( c = 0 ; c < sizeOfInput; c++) printf("Element: %d\n", a[c]); } I am using Micosoft Visual Studio Command Line Tool for compiling this on a Windows XP machine. cl /EHsc bubblesort01.c My friend gets the correct output on a dinosaur machine (code is compiled using TCC there). My output is unexpected. The array mysteriously grows in size, in between. If you change the code so that the variable sizeOfInput is changed to sizeOfInputt, it gives the expected results! A search done at Microsoft Visual C++ Developer Center doesn't give any results for "sizeOfInput". I am not a C/C++ expert, and am curious to find out why this happens - any C/C++ experts who can "shed some light" on this? Unrelated note: I seriously thought of rewriting the whole code to use quicksort or merge sort before posting it here. But, after all, it is not Stooge sort...

  • how to send text to a process in a shell script?

    - by Martin
    So I have a Linux program that runs in a while(true) loop, which waits for user input, process it and print result to stdout. I want to write a shell script that open this program, feed it lines from a txt file, one line at a time and save the program output for each line to a file. So I want to know if there is any command for: - open a program - send text to a process - receive output from that program Many thanks.

  • how to remove location block from $uri in nginx configuration?

    - by Jason
    I have a rewrite in my ngix conf file that works properly except it seems to include the location block as part of the $uri variable. I only want the path after the location block. My current config code is: location /cargo { try_files $uri $uri/ /cargo/index.php?_REWRITE_COMMAND=$uri&args; } Using an example url of http://localhost/cargo/testpage the redirect works, however the value of the "_REWRITE_COMMAND" parameter received by my php file is "/cargo/testpage". I need to strip off the location block and just have "testpage" as the $uri I am pretty sure there is a regex syntax to split the $uri and assign it to a new variable using $1 $2 etc, but I can't find any example to do just a variable assignment using a regex that is not part of a rewrite statement. I've been looking and trying for hours and I just can't seem to get past this last step. I also know I could just strip this out on the application code, but the reason I want to try to fix it in the nginx conf is for compatibility reasons as it also runs on Apache. I also should say that I have figured out a really hacky way to do it, but it involves an "if" statement to check for file existance and the documentation specifically says not to do it that way. -- UPDATE: ANSWERED BY theuni: The regex goes in the location block definition. one note of caution is that php handler location needs to be ABOVE this location, otherwise you will get a server error because it goes into an infinite redirect loop location ~ ^/cargo/(.*) { try_files $1 /cargo/$1/ /cargo/index.php?_REWRITE_COMMAND=$1&args; }
