  I'm using PostgreSQL. I have a table with 3 fields person, recipe and ingredient person = creator of the recipe recipe = the recipe ingredient = one of the ingredients in the recipe I want to create a query which results in every person who whenever has added carrot to a recipe, the person must also have added salt to the same recipe. More than one person can have created the recipe, in which case the person who added the ingredient will be credited for adding the ingredient. Sometimes the ingredient is used more than once, even by the same person. If this the table: person1, rec1, carrot person1, rec1, salt person1, rec1, salt person1, rec2, salt person1, rec2, pepper person2, rec1, carrot person2, rec1, salt person2, rec2, carrot person2, rec2, pepper person3, rec1, sugar person3, rec1, carrot Then I want this result: person1 Because this person is the only one who whenever has added carrot also have added salt.

• Add links to specific words within span tag in PHP

  - by dazhall

  I have a list of words that I'd like to add a link to, I can do this fairly easily using preg_match_all and preg_replace: $str = "<span class=\"cz\">Dám si jedno pivo prosím.</span> = I'll have a beer please."; preg_match_all('/[a-ztúuýžácdéeínórš]+/i',$str,$matches); $matches = array_unique($matches[0]); foreach ($matches as $match) { if(!empty($words[$match])) { $str = preg_replace("/(^|[^\w]){1}(".preg_quote($match,"/").")($|[^\w]){1}/i", '\\1<a href="#">\\2</a>\\3', $str); } } echo $str; What I'd like to do is restrict the linking to only within the span tag. My brain is all regex-ed out, so any help would be appreciated! Thanks! Darren.

• simple XML question for perl - how to retrieve specific elements

  - by Jeff

  I'm trying to figure out how to loop through XML but I've read a lot and I'm still getting stuck. Here's the info: I'm using the wordnik api to retrieve XML with XML::Simple: $content = get($url); $r = $xml->XMLin("$content"); The actual XML looks like this: <definitions> - <definition sequence="0" id="0"> - <text> To withdraw one's support or help from, especially in spite of duty, allegiance, or responsibility; desert: abandon a friend in trouble. </text> <headword>abandon</headword> <partOfSpeech>verb-transitive</partOfSpeech> </definition> - <definition sequence="1" id="0"> - <text> To give up by leaving or ceasing to operate or inhabit, especially as a result of danger or other impending threat: abandoned the ship. </text> <headword>abandon</headword> <partOfSpeech>verb-transitive</partOfSpeech> </definition> - <definition sequence="2" id="0"> - <text> To surrender one's claim to, right to, or interest in; give up entirely. See Synonyms at relinquish. </text> <headword>abandon</headword> <partOfSpeech>verb-transitive</partOfSpeech> </definition> - <definition sequence="3" id="0"> ... What I want is simply the FIRST definition's part of speech. I'm using this code but it's getting the LAST definition's POS: if($r->{definition}->{0}->{partOfSpeech}) { $pos = $r->{definition}->{0}->{partOfSpeech}; } else { $pos = $r->{definition}->{partOfSpeech}; } I am pretty embarrassed by this since I know there's an obviously better way to do it. I would love to get something as simple as this working so I could more generally loop through the elements. BUt it just isn't working for me (no idea what to reference). I've tried many variations of the following - this is just my last attempt: while (my ($k, $v) = each %{$r->{definitions}->{definition}[0]->{sequence}->{partOfSpeech}}) { $v =~ s/'/'"'"'/g; $v = "'$v'"; print "export $k=$v\n"; } Lastly, when I do "print Dumper($r)" it gives me this: $VAR1 = { 'definition' => { '0' => { 'partOfSpeech' => 'noun', 'sequence' => '6', 'text' => 'A complete surrender of inhibitions.', 'headword' => 'abandon' } } }; (And that "noun" you see is the last (6th) definition/partofspeech element).

• Apply a specific class to the first item in a series with PHP

  - by Thomas

  I have a php script that echoes a series of uploaded images and I need to apply a class to the first image echoed in the series. Is this possible? For example, if I want to display 10 images and apply a class to only the first image, how would I go about it? Here is the code, I am working with: <div id="gallery"> <?php query_posts('cat=7'); while(have_posts()) { the_post(); $image_tag = wp_get_post_image('return_html=true'); $resized_img = getphpthumburl($image_tag,'h=387&w=587&zc=1'); $url = get_permalink(); $Price ='Price'; $Location = 'Location'; $title = $post->post_title; echo "<a href='$url'><img src='$resized_img' width='587' height='387' "; echo "rel=\"<div class='gallery_title'><h2>"; echo $title; echo "</h2></div>"; echo "<div class='pre_box'>Rate:</div><div class='entry'>\$"; echo get_post_meta($post->ID, $Price, true); echo "</div><div class='pre_box'>Location:</div><div class='entry'>"; echo get_post_meta($post->ID, $Location, true); echo "</div>\""; echo "'/></a>"; echo ""; } ?> On line 13, the code looks like this: echo "<a href='$url'><img src='$resized_img' width='587' height='387' "; For the first item only, I need it to look like this: echo "<a href='$url' class='show'><img src='$resized_img' width='587' height='387' ";

• How to deploy jar artifacts directly from a maven repository to appserver specific directories

  - by Joshua

  I have JDBC driver dependencies (e.g. h2, mysql ..) which have to be copied under ${jboss.home}/common/lib before it is used by my EAR application. What would be the best way to directly copy from a maven repository into the above location instead of doing a manual copy. I would not prefer to store copies of the drivers as part of my SVN. Note: I currently specify this as a maven dependency and copy this artifact from the local repository, not sure if this is the best way to do solve this.

• Server.TransferRequest returns blank page on specific server

  - by jishi

  I'm facing an issue that seems to be related to configuration. I have a webapplication based on MonoRail, where we utilize the routing feature from MonoRail. On the first request after the application has started, the routing isn't initialized. To circumvent this, I have the following code in Application_OnError(): public virtual void Application_OnError() { if ( // identified as routing error ) Server.TransferRequest( Context.Request.RawUrl, false ); return; } Problem beeing that on our development server (which runs server 2008 R2, with IIS 7.5 and .NET 3.5) returns a blank page without headers, but on my workstation (which runs win7, IIS 7.5 and .NET 3.5) it works fine. What could be the cause of this? If the code in Application_OnError() throws an exception, what would be the expected output? I have verified the following: The access-log shows one entry, I'm not sure if a TransferRequest would show up as a second entry when invoked successfully The application actually do some work according to my internal logs, and it doesn't die since a subsequent requests works flawlessly (because routing will be active) Any hints on what to look for would be greatly appreciated!

• How to strip specific contents of a String in Java

  - by user2974877

  So I have a string, and I want to strip out some parts of it using, for example, the firt and last characters of the "interesting" part. String dirty = "$!$!%!%$something interesting&!!$!%$something interesting2"; And the output something like: String clean = "something interesting:something interesting2"; Note: The code needs to work without knowing the random part, changing everytime the program runs. I researched and only found code that does it, but only knowing the random segment.

• How to call a method of a specific class from another class (created in this specific class) ?

  - by choise

  I created a TTModelViewController. in the createModel Method i created a TTURLRequestModel. after Loading content in the TTURLRequestModel i want to call a method in my TTModelViewController. TTModelViewController - (void) createModel { requestModel = [[singlePostModel alloc] initWithId:@"54"]; } - (void)didLoadModel:(BOOL)firstTime { NSLog(@"loaded"); } TTURLRequestModel (singlePostModel) - (void)requestDidFinishLoad:(TTURLRequest*)request { //doing something [super requestDidFinishLoad:request]; } first i thought "didLoadModel" gets called after requestDidFinishLoad was called, but its before. So, how can i call a method in my TTModelViewController after request is finished loading? is there a method that already does that and i only have to overwrite this? or something else? thanks // if knowbody knows how to do this with three20, anybody can tell me how to do this in general?

• matlab: how to transform screen pixels into specific coordinates

  - by user3137385

  I have to draw a curve captured on a image using screen pixels (mouse clicks) into a coordinate system. E.g.: Pixels on the screen, from left to right (130 px to 970 px) correspond to the x-axis of my coordinate system (1000 to 6000). Pixels from bottom to top (670 to 99) correspond to the y-axis of coordinate system (0 to 1.2). How can this be done? Maybe there's a function in matlab doing something like that? Some more explanation: I have a jpg image of a curve on a coordinate system. I've got pixel positions (x,y) of several points on that curve. Now I want to plot same curve into a matlab figure with same x and y axis as on the jpg image.

• Set a datetime for next or previous sunday at specific time

  - by Marc

  I have an app where there is always a current contest (defined by start_date and end_date datetime). I have the following code in the application_controller.rb as a before_filter. def load_contest @contest_last = Contest.last @contest_last.present? ? @contest_leftover = (@contest_last.end_date.utc - Time.now.utc).to_i : @contest_leftover = 0 if @contest_last.nil? Contest.create(:start_date => Time.now.utc, :end_date => Time.now.utc + 10.minutes) elsif @contest_leftover < 0 @winner = Organization.order('votes_count DESC').first @contest_last.update_attributes!(:organization_id => @winner.id, :winner_votes => @winner.votes_count) if @winner.present? Organization.update_all(:votes_count => 0) Contest.create(:start_date => @contest_last.end_date.utc, :end_date => Time.now.utc + 10.minutes) end end My questions: 1) I would like to change the :end_date to something that signifies next Sunday at a certain time (eg. next Sunday at 8pm). Similarly, I could then set the :start_date to to the previous Sunday at a certain time. I saw that there is a sunday() class (http://api.rubyonrails.org/classes/Time.html#method-i-sunday), but not sure how to specify a certain time on that day. 2) For this situation of always wanting the current contest, is there a better way of loading it in the app? Would caching it be better and then reloading if a new one is created? Not sure how this would be done, but seems to be more efficient. Thanks!

• Disable page cache on a specific page

  - by David Brunelle

  Hi, Not sure if I really am on the right forum, but if not, just tell me. I have a page that is coded in ASP (not .net) which is used to send email. We are currently having a problem in which the page seem to be sent twice sometime. Upon checking, we found out that those who have this problem are coming from big organisation, so it was suggested that their server might cache the file for some reason. I would like to know, is there a way in HTML (or ASP ) to prevent that from happening ? Or is it in IIS that we must set this up ? Thanks,

• How to estimate memory need by XPathDocument for a specific xml file

  - by bill seacham

  Is there any way to estimate the memory requirement for creating an XpathDocument instance based on the file size of the xml? XpathDocument xdoc = new XpathDocument(xmlfile); Is there any way to programmatically stop the process of creating the XpathDocument if memory drops to a very low level? Since it loads the entire xml into memory, it would be nice to know ahead of time if the xml is too big. What I have found is that when I create a new XpathDocument with a big xml file, an outofmemory exception is never fired, but that the process slows to a crawl, only 5 Mb of memory remains a available and the Task Manager reports it is not responding. This happened with a 266 Mb xml file when there was 584 Mb of ram. I was able to load a 150 Mb file with no problems in 18. After loading the xml, I want to do xpath queries using an XpathNavigator and an XpathNodeIterator. I am using .net 2.0, xp sp3.

• Pull specific information from a long list with Perl

  - by melignus

  The file that I've got to work with here is the result of an LDAP extraction but I need to ultimately get the information formatted over to something that a spreadsheet can use. So, the data is as follows: DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData displayName: John Doe name: ##userName DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData displayName: Jane Doe name: ##userName DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData DataDataDataDataDataDataDataDataDataDataDataDataDataDataDataData displayName: Ted Doe name: ##userName The format that I need to export to is: firstName lastName userName firstName lastName userName firstName lastName userName Where the spaces are tabs so I can then impor that file into a database. I have experience doing this in VBScript but I'm trying to switch over to using Perl for as much server administration as possible. I'm not sure on the syntax for what I want which is basically while not endoffile{ detect "displayName: " & $firstName & " " & $lastName detect "name: ##" & $userName write $firstName tab $lastName tab $userName to file } Also if someone could point me to a resource specifically on the text parsing syntax that Perl uses, I'd be very grateful. Most of the resources that I've come across haven't been very helpful.
