  • Apache Getting Bogged Down By Certain Script (Wp-Cron.php) - How To Kill Process Automatically

    - by user50037
    I have a server that is running a number of wordpress blogs, and a number of them have several hundred/thousand posts. Every couple of days, the server slows to a crawl due to a file being run on Wordpress called WP-cron.php. My entire apache process log turns into this : http:// imgur.com/A7K9k.png Times that by quite a bit. And server no go. Each process takes up about 1.1% of ram. And when we have 50 of them on the go. It gets insane. Not all of them are coming from the same blog, they are pretty widespread. In the Apache process page of WHM, they are usually ALL set to the status of "C", which means closing. But they can sit there until they crash the server, and they still hold the memory. Just google "wp-cron.php load" and you will find plenty of people with similar issues. In anycase, we have think it is down to users adding a tonne of dead "pinglists" to their wordpress installation. Which in turn wordpress loops through them endlessly. Problem number 1. Does anyone have any other suggestions about what would cause the Wordpress file wp-cron.php to loop endlessly. I still think it is down to pings, because all of the people we have contacted about their account load going sky high, have had massive ping lists. Problem number 2. Even if it is down to excessive pinglists in wordpress. We cannot be babying every single account on the server waiting for it to start spawning the wp-cron processes. It often happens overnight, and I start getting SMS alerts at 2am about the load. I have CSF installed, which apparently would have ended the processes if they ran over XXX time. But I have been told that it won't catch the processes because they end up in this state of "closing" (They show up as "C" on the Apache page of WHM). Apparently CSF will only kill processes that are "running" which C does not count. I have seen various other scripts such as : http://dltj.org/article/die-apache-die/ . I took a look at the stat of /proc. But I was boggled at which delimited part was the time running. And if there was any way I could connect it back to an actual Apache process, so that I could see what file was running (So only close connections connected to wp-cron.php, with a state of "C"). Overall I know Problem 2 glosses over the real reason. But I do put the whole thing to excessive pinglists in Wordpress. But I just cannot sit there and babysit every single installation 24/7. So I need a way to save the server when I am not available. Any help would be much appreciated.

  • How do I make an external hard drive keep the same drive letter permanently?

    - by andygrunt
    I have a desktop PC (2002 vintage) running Windows XP that I turn on about 2 or 3 times per week. I have a mains powered 250Gb Western Digital hard disk connected to it via USB. I always turn the hard disk on before the PC so it's up and running as the PC boots. When I first connected the external hard disk, the PC assigned it a letter ('i' if it matters) and I've installed software to it, created shortcuts to various files and folders on the disk using that letter. For years everything was fine then I would boot the PC and the hard disk was assigned a different letter. I'd then have to go into 'my computer/manage/disk management' and manually change the letter back to 'i'. If I then rebooted the PC, the hard disk would usually still be 'i' but after the next reboot would be some other random letter and I have to manually change it back to 'i'. This would go on for some time then there'd be periods when the it would always be 'i' then, for no apparent reason (no new devices added, for example), the drive letter would start changing again. At the moment it's in random drive letter mood so I thought I'd ask the following question... How do I assign the external hard disk to be 'i' permanently? Answer: Thanks Molly that seems to have done the trick (after a little fiddling) - slightly disappointed there wasn't a way to do it within Windows without installing something else though. For anyone else trying this, it wasn't completely straightforward so here's what happened with me. I installed USBDLM as per the instructions on its website. I guessed that I had to assign the first USB letter to i so replaced the 'Letter1=' lines to 'Letter=I' in the ini file. To test it, I rebooted the PC only to find it came back up with the display set to 640x480 in 16 colours. After some investigation, I re-installed the display drivers and rebooted and set the display back to its usual setting. The external hard disk now gets set to 'i' but I found I had to re-apply sharing status to it so it was seen from my laptop which is on the same network. The end result of all this is that it now does what I wanted although it does act as though the hard drive has just been plugged in a few seconds after the Windows desktop appears i.e. the little box appears with a progress bar as it searches through the contents of the 'new' hard drive and I eventually get a dialogue box saying 'This disk or device contains more than one type of content. What do you want Windows to do?' and lists options such as play media files, print the pictures or open folder to view the files. This is a tiny pain I wish didn't happen but not exactly a huge price to pay. Other than that - it seems to work fine :) Looks like a spoke too soon... Every time I reboot, I have to re-share the 'i' drive (which I didn't have to do before) so it can be seen by my laptop on the same network. Any ideas how to make that permanent?

  • SharePoint 2010: CheckSuspiciousPhysicalPath exception

    - by Tommy Jakobsen
    I just installed SharePoint 2010 on my Windows Server 2008 R2 x64 server with SQL Server 2008. Everything is installed on this single server, and I configured SharePoint 2010 as described here: http://sharepoint.microsoft.com/blogs/fromthefield/Lists/Posts/Post.aspx?ID=112 Everything installed correct, and the SQL databases were created. But when I try to access the administration site through http://server:47632/_admin/adminconfigintro.aspx, I get the following exception: [HttpException] at System.Web.Util.FileUtil.CheckSuspiciousPhysicalPath(String physicalPath) at System.Web.CachedPathData.GetConfigPathData(String configPath) at System.Web.CachedPathData.GetConfigPathData(String configPath) at System.Web.CachedPathData.GetConfigPathData(String configPath) at System.Web.HttpContext.GetFilePathData() at System.Web.Configuration.CustomErrorsSection.GetSettings(HttpContext context, Boolean canThrow) at System.Web.HttpResponse.ReportRuntimeError(Exception e, Boolean canThrow, Boolean localExecute) at System.Web.HttpRuntime.FinishRequest(HttpWorkerRequest wr, HttpContext context, Exception e) The same error occurs when accessing http://server:47632/. Do you have any ideas whats causing this? I haven't been able to find anything about this issue. Edit 1: I just tried reinstalling SharePoint 2010 while monitoring the error log.

  • Wcf Facility Metadata publishing for this service is currently disabled.

    - by cvista
    Hey I'm trying to connect to my Wcf service which is configured using castles wcf facility. When I go to the service in a browser i get: Metadata publishing for this service is currently disabled. Which lists a load of instructions which i cant do because the configuration isnt in the web.config. when I try to connect using VS/add service reference i get: The HTML document does not contain Web service discovery information. Metadata contains a reference that cannot be resolved: 'http://s.ibzstar.com/userservices.svc'. Content Type application/soap+xml; charset=utf-8 was not supported by service http://s.ibzstar.com/userservices.svc. The client and service bindings may be mismatched. The remote server returned an error: (415) Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'.. If the service is defined in the current solution, try building the solution and adding the service reference again. Anyone know what I need to do to get this working? The end client is an iPhone app written using Monotouch if that matters - so no castle windsor on the client side. cheers w:// Here's the Windsor.config from the service: <?xml version="1.0" encoding="utf-8" ?> <configuration> <components> <component id="eventServices" service="IbzStar.Domain.IEventServices, IbzStar.Domain" type="IbzStar.Domain.EventServices, IbzStar.Domain" lifestyle="transient"> </component> <component id="userServices" service="IbzStar.Domain.IUserServices, IbzStar.Domain" type="IbzStar.Domain.UserServices, IbzStar.Domain" lifestyle="transient"> </component> The Web.config section: <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> <services> </services> <behaviors> <serviceBehaviors> <behavior name="IbzStar.WebServices.Service1Behavior"> <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> <serviceMetadata httpGetEnabled="true"/> <!-- To receive exception details in faults for debugging purposes, set the value below to true.

  • How to run Spring 3.0 PetClinic in tomcat with Hibernate backed JPA

    - by Zwei Steinen
    OK, this probably is supposed to be the easiest thing in the world, but I've been trying for the entire day, and it's still not working.. Any help is highly appreciated! What I did: Downloaded Tomcat 6.0.26 & Spring 3.0.1 Downloaded PetClinic from https://src.springframework.org/svn/spring-samples/petclinic Built & deployed petclinic.war. Ran fine with default TopLink persistence. Edited webapps/WEB-INF/spring/applicationContext-jpa.xml and changed jpaVendorAdaptor from TopLink to Hibernate. Edited webapps/WEB-INF/web.xml and changed context-param from applicationContext-jdbc.xml to applicationContext-jpa.xml Copied everything in the Spring 3.0.1 distribution to TOMCAT_HOME/lib. Launched tomcat. Saw Caused by: java.lang.IllegalStateException: ClassLoader [org.apache.catalina.loader.WebappClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:spring-agent.jar Uncommented line <Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/> in webapps/META-INF/context.xml. Same error. Added that line to TOMCAT_HOME/context.xml Deployed without error.

  • NSFetchedResultsController fetch request - updating predicate and UITableView

    - by Macatomy
    In my iPhone Core Data app I have it configured in a master-detail view setup. The master view is a UITableView that lists objects of the List entity. The List entity has a to-many relationship with the Task entity (called "tasks"), and the Task entity has an inverse to-one relationship with List called "list". When a List object is selected in the master view, I want the detail view (another UITableView) to list the Task objects that correspond to that List object. What I've done so far is this: In the detail view controller I've declared a property for a List object: @property (nonatomic, retain) List *list; Then in the master view controller I use this table view delegate method to set the list property of the detail view controller when a list is selected: - (void)tableView:(UITableView *)aTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSManagedObject *selectedObject = [[self fetchedResultsController] objectAtIndexPath:indexPath]; detailViewController.list = (List*)selectedObject; } Then, I've overriden the setter for the list property in the detail view controller like this: - (void)setList:(List*)newList { if (list != newList) { [list release]; list = [newList retain]; NSPredicate *newPredicate = [NSPredicate predicateWithFormat:@"(list == %@)", list]; [NSFetchedResultsController deleteCacheWithName:@"Root"]; [[[self fetchedResultsController] fetchRequest] setPredicate:newPredicate]; NSError *error = nil; if (![[self fetchedResultsController] performFetch:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } } } What I'm doing here is setting a predicate on the fetched results to filter out the objects so that I only get the ones that belong to the selected List object. The fetchedResultsController getter for the detail view controller looks like this: - (NSFetchedResultsController *)fetchedResultsController { if (fetchedResultsController == nil) { NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Task" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"FALSEPREDICATE"]; [fetchRequest setPredicate:predicate]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [aFetchedResultsController release]; [fetchRequest release]; [sortDescriptor release]; [sortDescriptors release]; } return fetchedResultsController; } Its almost unchanged from the default in the Core Data project template, the change I made is to add a predicate that always returns false, the reason being that when there is no List selected I don't want any items to be displayed in the detail view (if a list is selected the predicate is changed in the setter for the list property). However, when I select a list item, nothing really happens. Nothing in the table view changes, it stays empty. I'm sure my logic is flawed in several places, advice is appreciated Thanks

  • Card Shuffling in C#

    - by Jeff
    I am trying to write a code for a project that lists the contents of a deck of cards, asks how much times the person wants to shuffle the deck, and then shuffles them. It has to use a method to create two random integers using the System.Random class. These are my classes: Program.cs: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication3 { class Program { static void Main(string[] args) { Deck mydeck = new Deck(); foreach (Card c in mydeck.Cards) { Console.WriteLine(c); } Console.WriteLine("How Many Times Do You Want To Shuffle?"); } } } Deck.cs: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication3 { class Deck { Card[] cards = new Card[52]; string[] numbers = new string[] { "2", "3", "4", "5", "6", "7", "8", "9", "J", "Q", "K" }; public Deck() { int i = 0; foreach(string s in numbers) { cards[i] = new Card(Suits.Clubs, s); i++; } foreach (string s in numbers) { cards[i] = new Card(Suits.Spades, s); i++; } foreach (string s in numbers) { cards[i] = new Card(Suits.Hearts, s); i++; } foreach (string s in numbers) { cards[i] = new Card(Suits.Diamonds, s); i++; } } public Card[] Cards { get { return cards; } } } } classes.cs: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication3 { enum Suits { Hearts, Diamonds, Spades, Clubs } } Card.cs: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication3 { class Card { protected Suits suit; protected string cardvalue; public Card() { } public Card(Suits suit2, string cardvalue2) { suit = suit2; cardvalue = cardvalue2; } public override string ToString() { return string.Format("{0} of {1}", cardvalue, suit); } } } Please tell me how to make the cards shuffle as much as the person wants and then list the shuffled cards. Sorry about the formatting im new to this site.

  • PHP SimpleXML recursive function to list children and attibutes

    - by Phill Pafford
    I need some help on the SimpleXML calls for a recursive function that lists the elements name and attributes. Making a XML config file system but each script will have it's own config file as well as a new naming convention. So what I need is an easy way to map out all the elements that have attributes, so like in example 1 I need a simple way to call all the processes but I don't know how to do this without hard coding the elements name is the function call. Is there a way to recursively call a function to match a child element name? I did see the xpath functionality but I don't see how to use this for attributes. Any ideas? Also does the XML in the examples look correct? can I structure my XML like this? Example 1: <application> <processes> <process id="123" name="run batch A" /> <process id="122" name="run batch B" /> <process id="129" name="run batch C" /> </processes> <connections> <databases> <database usr="test" pss="test" hst="test" dbn="test" /> </databases> <shells> <ssh usr="test" pss="test" hst="test-2" /> <ssh usr="test" pss="test" hst="test-1" /> </shells> </connections> </application> Example 2: <config> <queues> <queue id="1" name="test" /> <queue id="2" name="production" /> <queue id="3" name="error" /> </queues> </config> Pseudo code: // Would return matching process id getProcess($process_id) { return the process attributes as array that are in the XML } // Would return matching DBN (database name) getDatabase($database_name) { return the database attributes as array that are in the XML } // Would return matching SSH Host getSSHHost($ssh_host) { return the ssh attributes as array that are in the XML } // Would return matching SSH User getSSHUser($ssh_user) { return the ssh attributes as array that are in the XML } // Would return matching Queue getQueue($queue_id) { return the queue attributes as array that are in the XML } EDIT: Can I pass two parms? on the first method you have suggested @Gordon public function findProcessById($id, $name) { $attr = false; $el = $this->xml->xpath("//process[@id='$id']"); // How do I also filter by the name? if($el && count($el) === 1) { $attr = (array) $el[0]->attributes(); $attr = $attr['@attributes']; } return $attr; }

  • Use Dojo Drag and Drop together with Dojo Moveable

    - by Select0r
    Hi, I'm using Dojo.dnd to transfer items between to areas. The problem is: the items will snap into place once I drop them, but I'd like to have them stay where I drop them, but only for one area. Here's a little code to explain this better: <div id="dropZone" class="dropZone"> <div id="itemNodes"></div> <div id="targetZone" dojoType="dojo.dnd.Source"></div> </div> "dropZone" is a DIV that contains two dojo.dnd.Source-areas, "itemNodes" (created programmatically) and "targetZone". Items (DIVs with images) should be dragged from a simple list out of "itemNodes" into "targetZone" and stay where they are dropped. As soon as they are dragged out of "targetZone" they should snap back to the list inside "itemNodes". Here's the code I use to create the items: var nodelist = new dojo.dnd.Source("itemNodes"); {Smarty-Loop} nodelist.insertNodes(false, ['<img class="dragItem" src="{$items->info.itemtext}" alt="{$items->info.itemtext}" border="0" />']); {/Smarty-Loop} But this way I just have two lists of items, the items dropped into "targetZone" won't stay where I dropped them. I've tried a loop dojo.query(".dojoDndItem").forEach(function(node) to grab all items and change them to a "moveable"-type: using dojo.dnd.move.constrainedMoveable will change the items so they can always be moved around (even in "itemNodes") using dojo.dnd.move.boxConstrainedMoveable and defining the "box" to the borders of "targetZone" makes it possible to just move the items around inside "targetZone", but as soon as I drop them, I can't grab and move them back out So here's the question: is it possible to create two dnd.Sources where I can move items back and forth and let the items be "moveable" only in one of the sources?Or is there a workaround like making the items moveable and if they're not dropped into "targetZone" they'll be moved back to the list in "itemNodes" automatically? Once the page is submitted, I have to save the position of every item that has been placed into "targetZone". (The next step will be positioning the items inside "targetZone" on page load if the grid has already been filled before, but I'd be happy to just get the thing working in the first place.) Any hint is appreciated. Greetings, Select0r

  • What is wrong with my PHP/MySQL code?

    - by James
    I am building a navigation menu which lists all my categories and subcategories. The problem is it returns only one of these and not all. I have the categories echoed inside the while loop so I'm not sure why it's only showing one result and not all: <?php $query = mysql_query("SELECT * FROM categories_parent"); while ($row = mysql_fetch_assoc($query)) { $id = $row['id']; $name = $row['name']; $slug = $row['slug']; $childStatus = $row['child_status']; // if has child categories if ($childStatus == "1") { echo "<li class='dir'><a href='category.php?slug=$slug'>$name</a>"; echo "<ul id='dropdown'>"; $query = mysql_query("SELECT * FROM categories_child WHERE parent=$id"); while ($row = mysql_fetch_assoc($query)) { $id = $row['id']; $name = $row['name']; $slug = $row['slug']; echo "<li><a href='category.php?slug=$slug'>$name</a></li>"; } echo "</ul>"; echo "</li>"; } // if singular parent else { echo "<li><a href='category.php?slug=$slug'>$name</a></li>"; } } ?> My database tables: -- -- Table structure for table `categories_child` -- CREATE TABLE IF NOT EXISTS `categories_child` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(1000) NOT NULL, `slug` varchar(1000) NOT NULL, `parent` int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=139 ; -- -- Dumping data for table `categories_child` -- INSERT INTO `categories_child` (`id`, `name`, `slug`, `parent`) VALUES (138, 'Britney Spears', 'category/celiberties/britney-spears/', 137), (136, 'Tigers', 'category/animals/tigers/', 136), (137, 'Horses', 'category/animals/horses/', 136), (135, 'Lions', 'category/animals/lions/', 136); -- -- Table structure for table `categories_parent` -- CREATE TABLE IF NOT EXISTS `categories_parent` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(1000) NOT NULL, `slug` varchar(1000) NOT NULL, `child_status` int(1) NOT NULL DEFAULT '0', PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=139 ; -- -- Dumping data for table `categories_parent` -- INSERT INTO `categories_parent` (`id`, `name`, `slug`, `child_status`) VALUES (137, 'Celiberties', 'category/celiberties/', 1), (138, 'TV Shows', 'category/tv-shows/', 0), (136, 'Animals', 'category/animals/', 1);

  • Oracle performance problem

    - by jreid42
    We are using an Oracle 11G machine that is very powerful; has redundant storage etc. It's a beast from what I have been told. We just got this DB for a tool that when I first came on as a coop had like 20 people using, now its upwards of 150 people. I am the only one working on it :( We currently have a system in place that distributes PERL scripts across our entire data center essentially giving us a sort of "grid" computing power. The Perl scripts run a sort of simulation and report back the results to the database. They do selects / inserts. The load is not very high for each script but it could be happening across 20-50 systems at the same time. We then have multiple data centers and users all hitting the same database with this same approach. Our main problem with this is that our database is getting overloaded with connections and having to drop some. We sometimes have upwards of 500 connections. These are old perl scripts and they do not handle this well. Essentially they fail and the results are lost. I would rather avoid having to rewrite a lot of these as they are poorly written, and are a headache to even look at. The database itself is not overloaded, just the connection overhead is too high. We open a connection, make a quick query and then drop the connection. Very short connections but many of them. The database team has basically said we need to lower the number of connections or they are going to ignore us. Because this is distributed across our farm we cant implement persistent connections. I do this with our webserver; but its on a fixed system. The other ones are perl scripts that get opened and closed by the distribution tool and thus arent always running. What would be my best approach to resolving this issue? The scripts themselves can wait for a connection to be open. They do not need to act immediately. Some sort of queing system? I've been suggested to set up a few instances of a tool called "SQL Relay". Maybe one in each data center. How reliable is this tool? How good is this approach? Would it work for what we need? We could have one for each data center and relay requests through it to our main database, keeping a pipeline of open persistent connections? Does this make sense? Is there any other suggestions you can make? Any ideas? Any help would be greatly appreciated. Sadly I am just a coop student working for a very big company and somehow all of this has landed all on my shoulders (there is literally nobody to ask for help; its a hardware company, everybody is hardware engineers, and the database team is useless and in India) and I am quite lost as what the best approach would be? I am extremely overworked and this problem is interfering with on going progress and basically needs to be resolved as quickly as possible; preferably without rewriting the whole system, purchasing hardware (not gonna happen), or shooting myself in the foot. HELP LOL!

  • This program runs but not correctly; the numbers aren't right.

    - by user320950
    this program runs but not correctly numbers arent right, i read numbers from a file and then when i am using them in the program they are not right.:brief decription of what i am trying to do can someone tell me if something doesnt look right. this is what i have to do: write a program that determines the grade dispersal for 100 students You are to read the exam scores into three arrays, one array for each exam. You must then calculate how many students scored A’s (90 or above), B’s (80 or above), C’s (70 or above), D’s (60 or above), and F’s (less than 60). Do this for each exam and write the distribution to the screen. // basic file operations #include <iostream> #include <fstream> using namespace std; int read_file_in_array(double exam[100][3]); double calculate_total(double exam1[], double exam2[], double exam3[]); // function that calcualates grades to see how many 90,80,70,60 //void display_totals(); double exam[100][3]; int main() { double go,go2,go3; double exam[100][3],exam1[100],exam2[100],exam3[100]; go=read_file_in_array(exam); go2=calculate_total(exam1,exam2,exam3); //go3=display_totals(); cout << go,go2,go3; return 0; } /* int display_totals() { int grade_total; grade_total=calculate_total(exam1,exam2,exam3); return 0; } */ double calculate_total(double exam1[],double exam2[],double exam3[]) { int calc_tot,above90=0, above80=0, above70=0, above60=0,i,j, fail=0; double exam[100][3]; calc_tot=read_file_in_array(exam); for(i=0;i<100;i++) { for (j=0; j<3; j++) { exam1[i]=exam[100][0]; exam2[i]=exam[100][1]; exam3[i]=exam[100][2]; if(exam[i][j] <=90 && exam[i][j] >=100) { above90++; { if(exam[i][j] <=80 && exam[i][j] >=89) { above80++; { if(exam[i][j] <=70 && exam[i][j] >=79) { above70++; { if(exam[i][j] <=60 && exam[i][j] >=69) { above60++; { if(exam[i][j] >=59) { fail++; } } } } } } } } } } } return 0; } int read_file_in_array(double exam[100][3]) { ifstream infile; int exam1[100]; int exam2[100]; int exam3[100]; infile.open("grades.txt");// file containing numbers in 3 columns if(infile.fail()) // checks to see if file opended { cout << "error" << endl; } int num, i=0,j=0; while(!infile.eof()) // reads file to end of line { for(i=0;i<100;i++) // array numbers less than 100 { for(j=0;j<3;j++) // while reading get 1st array or element infile >> exam[i][j]; infile >> exam[i][j]; infile >> exam[i][j]; cout << exam[i][j] << endl; { if (!

  • How does mysql define DISTINCT() in reference documentation

    - by goran
    EDIT: This question is about finding definitive reference to MySQL syntax on SELECT modifying keywords and functions. /EDIT AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax, but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best EDIT After asking the same question on mysql forums I learned that while parsing the SQL mysql does not care about whitespace between functions and column names (but I am still missing a reference). As it seems you can have whitespace between functions and the parenthesis SELECT LEFT (field1,1), field2... and get mysql to understand it as SELECT LEFT(field,1) Similarly SELECT DISTINCT(field1), field2... seems to get decomposed to SELECT DISTINCT (field1), field2... and then DISTINCT is taken not as some undefined (or undocumented) function, but as SELECT modifying keyword and the parenthesis around field1 are evaluated as if they were part of field expression. It would be great if someone would have a pointer to documentation where it is stated that the whitespace between functions and parenthesis is not significant or to provide links to apropriate MySQL forums, mailing lists where I could raise a question to put this into reference. EDIT I have found a reference to server option IGNORE SPACE. It states that "The IGNORE SPACE SQL mode can be used to modify how the parser treats function names that are whitespace-sensitive", later on it states that recent versions of mysql have reduced this number from 200 to 30. One of the remaining 30 is COUNT for example. With IGNORE SPACE enabled both SELECT COUNT(*) FROM mytable; SELECT COUNT (*) FROM mytable; are legal. So if this is an exception, I am left to conclude that normally functions ignore space by default. If functions ignore space by default then if the context is ambiguous, such as for the first function on a first item of the select expression, then they are not distinguishable from keywords and the error can not be thrown and MySQL must accept them as keywords. Still, my conclusions feel like they have lot of assumptions, I would still be grateful and accept any pointers to see where to follow up on this.

  • How to best design a date/geographic proximity query on GAE?

    - by Dane
    Hi all, I'm building a directory for finding athletic tournaments on GAE with web2py and a Flex front end. The user selects a location, a radius, and a maximum date from a set of choices. I have a basic version of this query implemented, but it's inefficient and slow. One way I know I can improve it is by condensing the many individual queries I'm using to assemble the objects into bulk queries. I just learned that was possible. But I'm also thinking about a more extensive redesign that utilizes memcache. The main problem is that I can't query the datastore by location because GAE won't allow multiple numerical comparison statements (<,<=,=,) in one query. I'm already using one for date, and I'd need TWO to check both latitude and longitude, so it's a no go. Currently, my algorithm looks like this: 1.) Query by date and select 2.) Use destination function from geopy's distance module to find the max and min latitude and longitudes for supplied distance 3.) Loop through results and remove all with lat/lng outside max/min 4.) Loop through again and use distance function to check exact distance, because step 2 will include some areas outside the radius. Remove results outside supplied distance (is this 2/3/4 combination inefficent?) 5.) Assemble many-to-many lists and attach to objects (this is where I need to switch to bulk operations) 6.) Return to client Here's my plan for using memcache.. let me know if I'm way out in left field on this as I have no prior experience with memcache or server caching in general. -Keep a list in the cache filled with "geo objects" that represent all my data. These have five properties: latitude, longitude, event_id, event_type (in anticipation of expanding beyond tournaments), and start_date. This list will be sorted by date. -Also keep a dict of pointers in the cache which represent the start and end indices in the cache for all the date ranges my app uses (next week, 2 weeks, month, 3 months, 6 months, year, 2 years). -Have a scheduled task that updates the pointers daily at 12am. -Add new inserts to the cache as well as the datastore; update pointers. Using this design, the algorithm would now look like: 1.) Use pointers to slice off appropriate chunk of list based on supplied date. 2-4.) Same as above algorithm, except with geo objects 5.) Use bulk operation to select full tournaments using remaining geo objects' event_ids 6.) Assemble many-to-manys 7.) Return to client Thoughts on this approach? Many thanks for reading and any advice you can give. -Dane

  • How to construct a flowchart/storyboard in a Func Spec

    - by PeterQ
    Hey I'm a bit embarrassed to write a post on this topic, but I would appreciate the help. At my school, the CS kids (myself included) have created a nice, little program that is built for incoming Chem/Bio students. It consists of several modules that reviews topics they should have a firm grasp on before they start their classes. It's a nice tool since it cuts down on reviewing the material in class but also allows the students to do a quick diagnostic to fix any problems. Now, I'm in charge of constructing a simple interface that reports on the progress of the group and individual students. The interface is pretty simple. It's just a window that pops up, and it has three tabs: the first tab is a "cumulative" report of all of students. The secnod tab has a drop down box that lists the students and once a student is selected, a report for him/her comes up. And the third tab is simply a description of all of the terms used in the 1st and 2nd tabs. Now, I'm trying to be a good CS student and write a func. spec for my interface. My problem comes with the fact that I'd like to insert a little flowchart using Visio. Problem is, and I'm quite embarrassed to admit this, I don't know how to construct the flowchart/storyboard. For instance, I know I start with a "Start/Click Icon" in a rectangle. Then where do I go? Do I draw three arrrows (one going to each tab) and then describing what goes on? In tab one, the only thing that happens is that the user will select a "sort" method in the drop down box. This will sort the list. The End. Similarly, if the user selects the second tab, then he will go to a drop down box with the student names. Selecting a name will bring up student info. And the third tab is just a list of unfamiliar terms coming from the first or second tab. I wanted to storyboard/flowchart what I'm doing, but I'm unclear how to go about it. Any help would be appreciated! (Just to clarify, I'm not having trouble with using Visio, but I don't know how one goes about construct a storyboard or determining the procedure for constructing one)

  • How to avoid using duplicate savepoint names in nested transactions in nested stored procs?

    - by Gary McGill
    I have a pattern that I almost always follow, where if I need to wrap up an operation in a transaction, I do this: BEGIN TRANSACTION SAVE TRANSACTION TX -- Stuff IF @error <> 0 ROLLBACK TRANSACTION TX COMMIT TRANSACTION That's served me well enough in the past, but after years of using this pattern (and copy-pasting the above code), I've suddenly discovered a flaw which comes as a complete shock. Quite often, I'll have a stored procedure calling other stored procedures, all of which use this same pattern. What I've discovered (to my cost) is that because I'm using the same savepoint name everywhere, I can get into a situation where my outer transaction is partially committed - precisely the opposite of the atomicity that I'm trying to achieve. I've put together an example that exhibits the problem. This is a single batch (no nested stored procs), and so it looks a little odd in that you probably wouldn't use the same savepoint name twice in the same batch, but my real-world scenario would be too confusing to post. CREATE TABLE Test (test INTEGER NOT NULL) BEGIN TRAN SAVE TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (1) COMMIT TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (2) COMMIT TRAN TX DELETE FROM Test ROLLBACK TRAN TX COMMIT TRAN TX SELECT * FROM Test DROP TABLE Test When I execute this, it lists one record, with value "1". In other words, even though I rolled back my outer transaction, a record was added to the table. What's happening is that the ROLLBACK TRANSACTION TX at the outer level is rolling back as far as the last SAVE TRANSACTION TX at the inner level. Now that I write this all out, I can see the logic behind it: the server is looking back through the log file, treating it as a linear stream of transactions; it doesn't understand the nesting/hierarchy implied by either the nesting of the transactions (or, in my real-world scenario, by the calls to other stored procedures). So, clearly, I need to start using unique savepoint names instead of blindly using "TX" everywhere. But - and this is where I finally get to the point - is there a way to do this in a copy-pastable way so that I can still use the same code everywhere? Can I auto-generate the savepoint name on the fly somehow? Is there a convention or best-practice for doing this sort of thing? It's not exactly hard to come up with a unique name every time you start a transaction (could base it off the SP name, or somesuch), but I do worry that eventually there would be a conflict - and you wouldn't know about it because rather than causing an error it just silently destroys your data... :-(

  • Setting up NCover for NUnit in FinalBuilder

    - by Lasse V. Karlsen
    I am attempting to set up NCover for usage in my FinalBuilder project, for a .NET 4.0 C# project, but my final coverage output file contains no coverage data. I am using: NCover 3.3.2 NUnit 2.5.4 FinalBuilder 6.3.0.2004 All tools are the latest official as of today. I've finally managed to coax FB into running my unit tests under NCover for the .NET 4.0 project, so I get Tests run: 184, ..., which is correct. However, the final Coverage.xml file output from NCover is almost empty, and looks like this: <?xml version="1.0" encoding="utf-8"?> <!-- saved from NCover 3.0 Export url='http://www.ncover.com/' --> <coverage profilerVersion="3.3.2.6211" driverVersion="3.3.2" exportversion="3" viewdisplayname="" startTime="2010-04-22T08:55:33.7471316Z" measureTime="2010-04-22T08:55:35.3462915Z" projectName="" buildid="27c78ffa-c636-4002-a901-3211a0850b99" coveragenodeid="0" failed="false" satisfactorybranchthreshold="95" satisfactorycoveragethreshold="95" satisfactorycyclomaticcomplexitythreshold="20" satisfactoryfunctionthreshold="80" satisfactoryunvisitedsequencepoints="10" uiviewtype="TreeView" viewguid="C:\Dev\VS.NET\LVK.IoC\LVK.IoC.Tests\bin\Debug\Coverage.xml" viewfilterstyle="None" viewreportstyle="SequencePointCoveragePercentage" viewsortstyle="Name"> <rebasedpaths /> <filters /> <documents> <doc id="0" excluded="false" url="None" cs="" csa="00000000-0000-0000-0000-000000000000" om="0" nid="0" /> </documents> </coverage> The output in FB log is: ... ***************** End Program Output ***************** Execution Time: 1,5992 s Coverage Xml: C:\Dev\VS.NET\LVK.IoC\LVK.IoC.Tests\bin\Debug\Coverage.xml NCover Success My configuration of the FB step for NCover: NCover what?: NUnit test coverage Command: C:\Program Files (x86)\NUnit 2.5.4\bin\net-2.0\nunit-console.exe Command arguments: LVK.IoC.Tests.dll /noshadow /framework:4.0.30319 /process=single /nothread Note: I've tried with and without the /process and /nothread options Working directory: %FBPROJECTDIR%\LVK.IoC.Tests\bin\Debug List of assemblies to profile: %FBPROJECTDIR%\LVK.IoC.Tests\bin\Debug\LVK.IoC.dll Note: I've tried just listing the name of the assembly, both with and without the extension. The documentation for the FB step doesn't help, as it only lists minor sentences for each property, and fails to give examples or troubleshooting hints. Since I want to pull the coverage results into NDepend to run build-time analysis, I want that file to contain the information I need. I am also using TestDriven, and if I right-click the solution file and select "Test with NCover", NCover-explorer opens up with coverage data, and if I ask it to show me the folder with coverage files, in there is an .xml file with the same structure as the one above, just with all the data that should be there, so the tools I have is certainly capable of producing it. Has anyone an idea of what I've configured wrong here?

  • Haskell newbie on types

    - by garulfo
    I'm completely new to Haskell (and more generally to functional programming), so forgive me if this is really basic stuff. To get more than a taste, I try to implement in Haskell some algorithmic stuff I'm working on. I have a simple module Interval that implements intervals on the line. It contains the type data Interval t = Interval t t the helper function makeInterval :: (Ord t) => t -> t -> Interval t makeInterval l r | l <= r = Interval l r | otherwise = error "bad interval" and some utility functions about intervals. Here, my interest lies in multidimensional intervals (d-intervals), those objects that are composed of d intervals. I want to separately consider d-intervals that are the union of d disjoint intervals on the line (multiple interval) from those that are the union of d interval on d separate lines (track interval). With distinct algorithmic treatments in mind, I think it would be nice to have two distinct types (even if both are lists of intervals here) such as import qualified Interval as I -- Multilple interval newtype MInterval t = MInterval [I.Interval t] -- Track interval newtype TInterval t = TInterval [I.Interval t] to allow for distinct sanity checks, e.g. makeMInterval :: (Ord t) => [I.Interval t] -> MInterval t makeMInterval is = if foldr (&&) True [I.precedes i i' | (i, i') <- zip is (tail is)] then (MInterval is) else error "bad multiple interval" makeTInterval :: (Ord t) => [I.Interval t] -> TInterval t makeTInterval = TInterval I now get to the point, at last! But some functions are naturally concerned with both multiple intervals and track intervals. For example, a function order would return the number of intervals in a multiple interval or a track interval. What can I do? Adding -- Dimensional interval data DInterval t = MIntervalStuff (MInterval t) | TIntervalStuff (TInterval t) does not help much, since, if I understand well (correct me if I'm wrong), I would have to write order :: DInterval t -> Int order (MIntervalStuff (MInterval is)) = length is order (TIntervalStuff (TInterval is)) = length is and call order as order (MIntervalStuff is) or order (TIntervalStuff is) when is is a MInterval or a TInterval. Not that great, it looks odd. Neither I want to duplicate the function (I have many functions that are concerned with both multiple and track intevals, and some other d-interval definitions such as equal length multiple and track intervals). I'm left with the feeling that I'm completely wrong and have missed some important point about types in Haskell (and/or can't forget enough here about OO programming). So, quite a newbie question, what would be the best way in Haskell to deal with such a situation? Do I have to forget about introducing MInterval and TInterval and go with one type only? Thanks a lot for your help, Garulfo

  • Conflict between Jquery Validate and Asp.net MVC

    - by chobo2
    Hi I am using asp.net mvc 2.0 and jquery validate 1.7 (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) What happens is this. A user can click on a link to edit a product. When a user clicks on which product they want to edit a jquery dialog box appears with a form of textboxes and dropdown lists. These html controls have information filled in them. Say if the user chooses to edit the Ipad product a dialog will appear and one of the form textboxes will have "Ipad" in it. Now this form gets rendered on the server side(the form is in a partial view). When loading the dialog box a ajax request is made to get that partial view and in the response part of the ajax call I do something like $('#EditDialog).html(ajaxresponse).dialog({...}); So I would have something like this rendered in my dialog box <form id="EditProduct"> Product Name: <input type="text" value="IPad" name="ProductName" /> </form> Now my jquery validate would be something like this. $("#EditProduct").validate( { errorContainer: "#Errorbox", errorLabelContainer: "#Errorbox ul", wrapper: "li", rules: { ProductName: "required" } }); So I know this works because I use the same validate for add product and if you try to leave ProductName blank it will show a validation error. Now it does not work with the edit one though and I think I know the reason why but not how to fix it. The value for the textbox is "IPad" this is how the Html.TextBoxFor() renders it. However if a user goes and changes the product name to "Iphone" or blank the value never changes. It is always "Ipad" in the html. So I think when the validate goes and looks it goes oh there is a value already in it. It is valid even though in reality it might be blank. When I post to the server through ajax it gets the right value and the server side validation stops it but my entire clientside validation is rendered useless because of this problem as it will never change the html.

  • Interactive Data Language, IDL: Does anybody care?

    - by Alex
    Anyone use a language called Interactive Data Language, IDL? It is popular with scientists. I think it is a poor language because it is proprietary (every terminal running it has to have an expensive license purchased) and it has minimal support (try searching for IDL, the language, right now on stack) . I am trying to convince my colleagues to stop using it and learn C/C++/Python/Fortran/Java/Ruby. Does anybody know about or even care about IDL enough to have opinions on it? What do you think of it? Should I tell my colleagues to stop wasting their time on it now? How can I convince them? Edit: People are getting the impression that I don't know or use IDL. Also, I said IDL has minimal support which is true in one sense, so I must clarify that the scientific libraries are indeed large. I use IDL all the time, but this is exactly the problem: I am only using IDL because colleagues use it. There is a file format IDL uses, the .sav, which can only be opened in IDL. So I must use IDL to work with this data and transfer the data back to colleagues, but I know I would be more efficient in another language. This is like someone sending you a microsoft word file in an email attachment and if you don't understand how wrong that is then you probably write too many words not enough code and you bought microsoft word. Edit: As an alternative to IDL Python is popular. Here is a list of The Pros of IDL (and the cons) from AstroBetter: Pros of IDL Mature many numerical and astronomical libraries available Wide astronomical user base Numerical aspect well integrated with language itself Many local users with deep experience Faster for small arrays Easier installation Good, unified documentation Standard GUI run/debug tool (IDLDE) Single widget system (no angst about which to choose or learn) SAVE/RESTORE capability Use of keyword arguments as flags more convenient Cons of IDL Narrow applicability, not well suited to general programming Slower for large arrays Array functionality less powerful Table support poor Limited ability to extend using C or Fortran, such extensions hard to distribute and support Expensive, sometimes problem collaborating with others that don’t have or can’t afford licenses. Closed source (only RSI can fix bugs) Very awkward to integrate with IRAF tasks Memory management more awkward Single widget system (useless if working within another framework) Plotting: Awkward support for symbols and math text Many font systems, portability issues (v5.1 alleviates somewhat) not as flexible or as extensible plot windows not intrinsically interactive (e.g., pan & zoom) Pros of Python Very general and powerful programming language, yet easy to learn. Strong, but optional, Object Oriented programming support Very large user and developer community, very extensive and broad library base Very extensible with C, C++, or Fortran, portable distribution mechanisms available Free; non-restrictive license; Open Source Becoming the standard scripting language for astronomy Easy to use with IRAF tasks Basis of STScI application efforts More general array capabilities Faster for large arrays, better support for memory mapping Many books and on-line documentation resources available (for the language and its libraries) Better support for table structures Plotting framework (matplotlib) more extensible and general Better font support and portability (only one way to do it too) Usable within many windowing frameworks (GTK, Tk, WX, Qt…) Standard plotting functionality independent of framework used plots are embeddable within other GUIs more powerful image handling (multiple simultaneous LUTS, optional resampling/rescaling, alpha blending, etc) Support for many widget systems Strong local influence over capabilities being developed for Python Cons of Python More items to install separately Not as well accepted in astronomical community (but support clearly growing) Scientific libraries not as mature: Documentation not as complete, not as unified Not as deep in astronomical libraries and utilities Not all IDL numerical library functions have corresponding functionality in Python Some numeric constructs not quite as consistent with language (or slightly less convenient than IDL) Array indexing convention “backwards” Small array performance slower No standard GUI run/debug tool Support for many widget systems (angst regarding which to choose) Current lack of function equivalent to SAVE/RESTORE in IDL matplotlib does not yet have equivalents for all IDL 2-D plotting capability (e.g., surface plots) Use of keyword arguments used as flags less convenient Plotting: comparatively immature, still much development going on missing some plot type (e.g., surface) 3-d capability requires VTK (though matplotlib has some basic 3-d capability)

  • SmoApplication.EnumAvailableSqlServers returns server names but not instance names (but only on one

    - by Matma
    Hi, There are a number of questions about this and a number of possible causes and thus far ive tried them all with no success. situation: i have an app that needs a db to work, onstartup it does a SmoApplication.EnumAvailableSqlServers(false) to get all the instances on the network, shows the user a dropdown, they pick one and i go connect to my db on that server. all good problem: this works on my machine, the guys next to me and others. HOWEVER it doesnt work on one of the tech guys machines (and potentially others). we are all on the same network domain, physically connected (no wireless), all logged on with network user names, all running the same sql express 2005 sp3, though im using win7 the other guys are running xppro. MSSMS on all machines can see all the instances when you select "Browse for more". yet on this one tech guys machine it lists his local instance (since its hardcoded to) and all the network servers, but has no instances names? i.e. .sqlexpress server1 server2 server3 server4 but on my machine and others we get: .sqlexpress server1/sqlexpress server2/sqlexpress server3/sqlexpress server4/sqlexpress the code im using: ' .... some code ' this populates my datatable dtServers = SmoApplication.EnumAvailableSqlServers(False) '.... some code '.... then later i ShowServers(...) Private dtServers As DataTable = Nothing Private Sub ShowServers(ByVal SQLInstance As String) ' Create a DataTable where we enumerate the available servers cmbServer.Items.Clear() cmbDatabase.Items.Clear() ' If there are any (network listed) servers at all If (dtServers.Rows.Count > 0) Then ' Loop through each server in the DataTable For Each drServer As DataRow In dtServers.Rows ' Add the name to the combobox cmbServer.Items.Add(drServer("Server") & "\" & drServer("Instance")) Next End If 'To make life simpler (add the local instance of sql express): cmbServer.Items.Add(SQLInstance) ' select first item If cmbServer.Items.Count > 0 Then cmbServer.SelectedIndex = 0 End If End Sub now i know this uses udp and its not 100%, but how come his machine is 100% consistent in not showing remote instances, and mine is 100 consistent showing them. even a udl file on his desktop cant see them, regarldess of provider i choose to use? some of the suggestions are to uninstall and re-install, but that doesnt seem like a solution as i (and most others) can see the instances, but one guy cant. this suggests its not the remote sql server but rather the local machine. Notes: ive tried firewall 1433, 1434 i can connect using a udl with full SERVERNAME\INSTANCENAME the browser service is running locally and on the remote machine ive tried stopping and restarting both the browser service on the local and remote machine. Ideas?

  • print a linear linked list into a table

    - by user1796970
    I am attempting to print some values i have stored into a LLL into a readable table. The data i have stored is the following : DEBBIE STARR F 3 W 1000.00 JOAN JACOBUS F 9 W 925.00 DAVID RENN M 3 H 4.75 ALBERT CAHANA M 3 H 18.75 DOUGLAS SHEER M 5 W 250.00 SHARI BUCHMAN F 9 W 325.00 SARA JONES F 1 H 7.50 RICKY MOFSEN M 6 H 12.50 JEAN BRENNAN F 6 H 5.40 JAMIE MICHAELS F 8 W 150.00 i have stored each firstname, lastname, gender, tenure, payrate, and salary into their own List. And would like to be able to print them out in the same format that they are viewed on the text file i read them in from. i have messed around with a few methods that allow me to traverse and print the Lists, but i end up with ugly output. . . here is my code for the storage of the text file and the format i would like to print out: public class Payroll { private LineWriter lw; private ObjectList output; ListNode input; private ObjectList firstname, lastname, gender, tenure, rate, salary; public Payroll(LineWriter lw) { this.lw = lw; this.firstname = new ObjectList(); this.lastname = new ObjectList(); this.gender = new ObjectList(); this.tenure = new ObjectList(); this.rate = new ObjectList(); this.salary = new ObjectList(); this.output = new ObjectList(); this.input = new ListNode(); } public void readfile() { File file = new File("payfile.txt"); try{ Scanner scanner = new Scanner(file); while(scanner.hasNextLine()) { String line = scanner.nextLine(); Scanner lineScanner = new Scanner(line); lineScanner.useDelimiter("\\s+"); while(lineScanner.hasNext()) { firstname.insert1(lineScanner.next()); lastname.insert1(lineScanner.next()); gender.insert1(lineScanner.next()); tenure.insert1(lineScanner.next()); rate.insert1(lineScanner.next()); salary.insert1(lineScanner.next()); } } }catch(FileNotFoundException e) {e.printStackTrace();} } public void printer(LineWriter lw) { String msg = " FirstName " + " LastName " + " Gender " + " Tenure " + " Pay Rate " + " Salary "; output.insert1(msg); System.out.println(output.getFirst()); System.out.println(" " + firstname.getFirst() + " " + lastname.getFirst() + "\t" + gender.getFirst() + "\t" + tenure.getFirst() + "\t" + rate.getFirst() + "\t" + salary.getFirst()); } }

  • Client-side templating frameworks to streamline using jQuery with REST/JSON

    - by Tauren
    I'm starting to migrate some html generation tasks from a server-side framework to the client. I'm using jQuery on the client. My goal is to get JSON data via a REST api and use this data to populate HTML into the page. Right now, when a user on my site clicks a link to My Projects, the server generates HTML like this: <dl> <dt>Clean Toilet</dt> <dd>Get off your butt and clean this filth!</dd> <dt>Clean Car</dt> <dd>I think there's something growing in there...</dd> <dt>Replace Puked on Baby Sheets</dt> </dl> I'm changing this so that clicking My Projects will now do a GET request that returns something like this: [ { "name":"Clean Car", "description":"I think there's something growing in there..." }, { "name":"Clean Toilets", "description":"Get off your butt and clean this filth!" }, { "name":"Replace Puked on Baby Sheets" } ] I can certainly write custom jQuery code to take that JSON and generate the HTML from it. This is not my question, and I don't need advice on how to do that. What I'd like to do is completely separate the presentation and layout from the logic (jquery code). I don't want to be creating DL, DT, and DD elements via jQuery code. I'd rather use some sort of HTML templates that I can fill the data in to. These templates could simply be HTML snippets that are hidden in the page that the application was loaded from. Or they could be dynamically loaded from the server (to support user specific layouts, i18n, etc.). They could be displayed a single time, as well as allow looping and repeating. Perhaps it should support sub-templates, if/then/else, and so forth. I have LOTS of lists and content on my site that are presented in many different ways. I'm looking to create a simple and consistent way to generate and display content without creating custom jQuery code for every different feature on my site. To me, this means I need to find or build a small framework on top of jQuery (probably as a plugin) that meets these requirements. The only sort of framework that I've found that is anything like this is jTemplates. I don't know how good it is, as I haven't used it yet. At first glance, I'm not thrilled by it's template syntax. Anyone know of other frameworks or plugins that I should look into? Any blog posts or other resources out there that discuss doing this sort of thing? I just want to make sure that I've surveyed everything out there before building it myself. Thanks!
