  • CMS for managing plain-text content, with tagging

    - by user575606
    Hi, We have some quite-specific requirements for our app that a CMS may help us with, and were hoping that someone may know of a CMS that matches these requirements (it's quite a laborous task to download each CMS and verify this manually). We want a CMS to allow users to create and manage articles, but storing the articles in plain-text only. All of the CMSs that we have looked at so far are geared towards creating HTML pages. We want the CMS to manage workflow (approval process), and tracking of history. The requirements for plain text only is that the intent is to allow business people to generate content which we are going to display in our Silverlight application - we don't want to go down the route of hosting and displaying arbitrary HTML in the app as we want the styling to be seamless with our app, amongst other reasons. We would also want to allow the user to be able to link between articles, but not to external sites (i.e. HTML with no formatting, or some other way of specifying article links), and the third requirement is the ability to tag articles and search on articles. Does anyone know of any non-HTML targetted CMS systems that may match these requirements? Thanks, Gary

  • Creating a Linq->HQL provider

    - by Mike Q
    Hi all, I have a client application that connects to a server. The server uses hibernate for persistence and querying so it has a set of annotated hibernate objects for persistence. The client sends HQL queries to the server and gets responses back. The client has an auto-generated set of objects that match the server hibernate objects for query results and basic persistence. I would like to support using Linq to query as well as Hql as it makes the queries typesafe and quicker to build (no more typos in HQL string queries). I've looked around at the following but I can't see how to get them to fit with what I have. NHibernate's Linq provider - requires using NHibernate ISession and ISessionFactory, which I don't have LinqExtender - requires a lot of annotations on the objects and extending a base type, too invasive What I really want is something that will generate give me a nice easy to process structure to build the HQL queries from. I've read most of a 15 page article written by one of the C# developers on how to create custom providers and it's pretty fraught, mainly because of the complexity of the expression tree. Can anyone suggest an approach for implementing Linq - HQL translation? Perhaps a library that will the cleanup of the expression tree into something more SQL/HQLish. I would like to support select/from/where/group by/order by/joins. Not too worried about subqueries.

  • getting service from wsdd via xpath not wroking

    - by subes
    Hi, I am trying to get the XPath "/deployment/service". Tested on this site: http://www.xmlme.com/XpathTool.aspx <?xml version="1.0" encoding="UTF-8" standalone="no"?> <deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org /axis/wsdd/providers/java"> <service name="kontowebservice" provider="java:RPC" style="rpc" use="literal"> <parameter name="wsdlTargetNamespace" value="http://strategies.spine"/> <parameter name="wsdlServiceElement" value="ExposerService"/> <parameter name="wsdlServicePort" value="kontowebservice"/> <parameter name="className" value="dmd4biz.container.webservice.konto.internal.KontoWebServiceImpl_WS"/> <parameter name="wsdlPortType" value="Exposer"/> <parameter name="typeMappingVersion" value="1.2"/> <operation xmlns:operNS="http://strategies.spine" xmlns:rtns="http://www.w3.org/2001/XMLSchema" name="expose" qname="operNS:expose" returnQName="exposeReturn" returnType="rtns:anyType" soapAction=""> <parameter xmlns:tns="http://www.w3.org/2001/XMLSchema" qname="in0" type="tns:anyType"/> </operation> <parameter name="allowedMethods" value="expose"/> <parameter name="scope" value="Request"/> </service> </deployment> I absolutely can't find out why it always tells me that my xpath does not match...

  • Problem executing trackPageview with Google Analytics.

    - by dmrnj
    I'm trying to capture the clicks of certain download links and track them in Google Analytics. Here's my code var links = document.getElementsByTagName("a"); for (var i = 0; i < links.length; i++) { linkpath = links[i].pathname; if( linkpath.match(/\.(pdf|xls|ppt|doc|zip|txt)$/) || links[i].href.indexOf("mode=pdf") >=0 ){ //this matches our search addClickTracker(links[i]); } } function addClickTracker(obj){ if (obj.addEventListener) { obj.addEventListener('click', track , true); } else if (obj.attachEvent) { obj.attachEvent("on" + 'click', track); } } function track(e){ linkhref = (e.srcElement) ? e.srcElement.pathname : this.pathname; pageTracker._trackPageview(linkhref); } Everything up until the pageTracker._trackPageview() call works. In my debugging linkhref is being passed fine as a string. No abnormal characters, nothing. The issue is that, watching my http requests, Google never makes a second call to the tracking gif (as it does if you call this function in an "onclick" property). Calling the tracker from my JS console also works as expected. It's only in my listener. Could it be that my listener is not deferring the default action (loading the new page) before it has a chance to contact Google's servers? I've seen other tracking scripts that do a similar thing without any deferral.

  • PHP/Javascript limiting amount of checkboxes

    - by Carl294
    Hi everyone Im trying to limit the amount of checkboxes that can be checked, in this case only 3 can be checked. When using plain HTML this works fine. The code can be seen below. HTML example <td ><input type=checkbox name=ckb value=2 onclick='chkcontrol()';></td><td>Perl</td> Javascript Function <script type="text/javascript"> function chkcontrol(j) { var total=0; for(var i=0; i < document.form1.ckb.length; i++){ if(document.form1.ckb[i].checked){ total =total +1;} if(total > 3){ alert("Please Select only three") document.form1.ckb[j].checked = false; return false; } } } </script> The problem appears when replacing the fixed HTML values with values from a MYSQL database. All the information appears correctly, and can be posted to another page via a submit button. However, it seems like the 'value' assigned to each record from the database is not making its way too the javascript function. <td><input name="checkbox[]" type="checkbox" value="<?php echo $rows['TCA_QID'];?>" onclick="chkcontrol();"></td> I have tried changed the name in the javascript function to match the 'checkbox' name.Any advice would be greatly appreciated Thanks

  • Facebook SSO authorize in safari but not in facebook app

    - by Pedro Calero
    My problem: I has developed an app with Facebook SSO in my iPhone/iPad. It was working OK. But I have changed the certificate of my app (so now it has new app ID). I also have changed the "iOS pack ID" property in Facebook: I deleted the old app ID and I added the new one. But now my app doesn't do the Facebook SSO when Facebook app is installed. It does it OK when Facebook app is not installed and it uses Safari. I have read this question and this question that say the problem is the "iOS pack ID" and app ID don't match. I have checked it a lot of times, and it is the same. I have put the old app ID in the "iOS pack ID" property of Facebook, but it still doesn't work. I don't know if Facebook take a time to check if my app ID is valid, and how they show the result. I have been a lot of time with this issue. It seem like the problem is the iOS pack ID is not exactly the app ID, but it is not the problem: they are exactly the same. Thank you very much.

  • Combine Lists with Same Heads in a 2D List (OCaml)

    - by Atticus
    Hi guys, I'm working with a list of lists in OCaml, and I'm trying to write a function that combines all of the lists that share the same head. This is what I have so far, and I make use of the List.hd built-in function, but not surprisingly, I'm getting the failure "hd" error: let rec combineSameHead list nlist = match list with | [] -> []@nlist | h::t -> if List.hd h = List.hd (List.hd t) then combineSameHead t nlist@uniq(h@(List.hd t)) else combineSameHead t nlist@h;; So for example, if I have this list: [[Sentence; Quiet]; [Sentence; Grunt]; [Sentence; Shout]] I want to combine it into: [[Sentence; Quiet; Grunt; Shout]] The function uniq I wrote just removes all duplicates within a list. Please let me know how I would go about completing this. Thanks in advance!

  • problem using the xsl method for-each

    - by joe
    Using XSL I am trying to turn this XML: <book><title>This is a <b>great</b> book</title></book> into this XML: <book>This is a <bold>great</bold> book</book> using this xsl: <xsl:for-each select="book/title/*"> <xsl:choose> <xsl:when test="name() = 'b'"> <bold> <xsl:value-of select="text()"/> </bold> </xsl:when> <xsl:otherwise> <xsl:value-of select="text()"/> </xsl:otherwise> </xsl:choose> </xsl:for-each> but my output is looking like this: <book><bold>great</bold></bold> Can anyone explain why the root text of <title> is getting lost? I believe my for-each select statement may need to be modified but I can't figure out what is should be. Keep in mind that I cannot use an <xsl:template match> because of the complexity of my style sheet. Thanks!

  • Most efficient way to bind a Listbox with SelectionMode=Multiple

    - by Draak
    Hi, I have an ASP.NET webform that has a listbox (lbxRegions) with multi-select option enabled. In my db, I have a table with an xml field that holds a list of regions. I need to populate the listbox with all available regions and then "check off" the list items that match the regions in the db table. The list options also need to be ordered by region name. So, I wrote the following code that works just fine -- no problems. But I was wondering if anyone can think of a better (more succinct, more efficient) way to have done the same thing. Thanks in advance. Dim allRegions = XElement.Load(Server.MapPath(Request.ApplicationPath) & "\Regions.xml").<country>.<regions>.<region> Dim selectedRegions = (From ev In dc.Events Where ev.EventId = 2951).Single.CEURegions.<country>.<regions>.<region> Dim unselectedRegions = allRegions.Except(selectedRegions) Dim selectedItems = From x In selectedRegions Select New ListItem() _ With {.Value = x.@code, .Text = x.Value, .Selected = True} Dim unselectedItems = From x In unselectedRegions Select New ListItem() _ With {.Value = x.@code, .Text = x.Value} Dim allItems = selectedItems.Union(unselectedItems).OrderBy(Function(x) x.Text) lbxRegions.Items.AddRange(allItems.ToArray()) P.S. You can post code in C# if you like.

  • How does this RegEx for parsing emails work in PHP?

    - by George Edison
    Okay, I have the following PHP code to extract an email address of the following two forms: Random Stranger <[email protected]> [email protected] Here is the PHP code: // The first example $sender = "Random Stranger <[email protected]>"; $pattern = '/([\w_-]*@[\w-\.]*)|.*<([\w_-]*@[\w-\.]*)>/'; preg_match($pattern,$sender,$matches,PREG_OFFSET_CAPTURE); echo "<pre>"; print_r($matches); echo "</pre><hr>"; // The second example $sender = "[email protected]"; preg_match($pattern,$sender,$matches,PREG_OFFSET_CAPTURE); echo "<pre>"; print_r($matches); echo "</pre>"; My question is... what is in $matches? It seems to be a strange collection of arrays. Which index holds the match from the parenthesis? How can I be sure I'm getting the email address and only the email address? Update: Here is the output: Array ( [0] => Array ( [0] => Random Stranger [1] => 0 ) [1] => Array ( [0] => [1] => -1 ) [2] => Array ( [0] => [email protected] [1] => 5 ) ) Array ( [0] => Array ( [0] => [email protected] [1] => 0 ) [1] => Array ( [0] => [email protected] [1] => 0 ) )

  • How to patch an S4 method in an R package?

    - by Richie Cotton
    If you find a bug in a package, it's usually possible to patch the problem with fixInNamespace, e.g. fixInNamespace("mean.default", "base"). For S4 methods, I'm not sure how to do it though. The method I'm looking at is in the gWidgetstcltk package. You can see the source code with getMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk")) I can't find the methods with fixInNamespace. fixInNamespace(".svalue", "gWidgetstcltk") Error in get(subx, envir = ns, inherits = FALSE) : object '.svalue' not found I thought setMethod might do the trick, but setMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk"), definition = function (obj, toolkit, index = NULL, drop = NULL, ...) { widget = getWidget(obj) sel <- unlist(strsplit(tclvalue(tcl(widget, "selection")), " ")) if (length(sel) == 0) { return(NA) } theChildren <- .allChildren(widget) indices <- sapply(sel, function(i) match(i, theChildren)) inds <- which(visible(obj))[indices] if (!is.null(index) && index == TRUE) { return(inds) } if (missing(drop) || is.null(drop)) drop = TRUE chosencol <- tag(obj, "chosencol") if (drop) return(obj[inds, chosencol, drop = drop]) else return(obj[inds, ]) }, where = "package:gWidgetstcltk" ) Error in setMethod(".svalue", c("gTabletcltk", "guiWidgetsToolkittcltk"), : the environment "gWidgetstcltk" is locked; cannot assign methods for function ".svalue" Any ideas?

  • Connect Rails model to non-rails database

    - by the_snitch
    I'm creating a new web application (Rails 3 beta), of which pieces of it will access data from a legacy mysql database that a current php application is using. I do not wish to modify the legacy db schema, I just want to be able to read/write to it, as well as the rails application having it's own database using activerecord for the newer stuff. I'm using mysql for the rails app, so I have the adapter installed. How is the best way to do this? For example, I want contacts to come from the old database. Should I create a contacts controller, and manually call sql to get the variables for the views? Or should I create a Contact model, and define attributes that match the fields in the database, and am I able to use it like Contact.mail_address to have it call "SELECT mailaddr FROM contacts WHERE id=Contact.id". Sorry, I've never done much in Rails outside of the standard stuff that is documented well. I'm not sure of what the best approach would be. Ideally, I want the contacts to be presented to my rails application as native as possible, so that I can expose them RESTfully for API access. Any suggestions and code examples would be much appreciated

  • Five unique, random numbers from a subset

    - by tau
    I know similar questions come up a lot and there's probably no definitive answer, but I want to generate five unique random numbers from a subset of numbers that is potentially infinite (maybe 0-20, or 0-1,000,000). The only catch is that I don't want to have to run while loops or fill an array. My current method is to simply generate five random numbers from a subset minus the last five numbers. If any of the numbers match each other, then they go to their respective place at the end of the subset. So if the fourth number matches any other number, it will bet set to the 4th from the last number. Does anyone have a method that is "random enough" and doesn't involve costly loops or arrays? Please keep in mind this a curiosity, not some mission-critical problem. I would appreciate it if everyone didn't post "why are you having this problem?" answers. I am just looking for ideas. Thanks a lot!

  • How to make ActionController::Base.asset_host and Base.relative_url_root independent?

    - by GSP
    In our Intranet environment we have a decree that common assets (stylesheets, images, etc) should be fed from Apache root while Rails apps runs from from a "sub directory" (a proxy to a Mongrel cluster). In other words: <%= stylesheet_tag '/common' %> # <link href="http://1.1.1.1/stylesheets/common.css" /> <%= link_to 'Home', :controller=>'home', :action=>'index' %> # <a href="http://1.1.1.1/myapp/" /> What I would like to do is define the assets and relative url in my configuration like this: ActionController::Base.asset_host=http://1.1.1.1 ActionController::Base.relative_url_root=/myapp But when I do this, the relative_url_root value gets appended to the asset_host value. (e.g. <link href="http://1.1.1.1/myapp/stylesheets/common.css"> ) Is there a way to stop this? And, more importantly, is there a best practice for how to deploy a rails app to an environment like this? (BTW, I don't want to simply hard code my asset paths since the development environment does not match the test and production environments.) Environment: Rails 2.3.4 Ruby 1.8.7 RedHat Linux 5.4?

  • What should i do for accomodating large scale data storage and retrieval?

    - by kailashbuki
    There's two columns in the table inside mysql database. First column contains the fingerprint while the second one contains the list of documents which have that fingerprint. It's much like an inverted index built by search engines. An instance of a record inside the table is shown below; 34 "doc1, doc2, doc45" The number of fingerprints is very large(can range up to trillions). There are basically following operations in the database: inserting/updating the record & retrieving the record accoring to the match in fingerprint. The table definition python snippet is: self.cursor.execute("CREATE TABLE IF NOT EXISTS `fingerprint` (fp BIGINT, documents TEXT)") And the snippet for insert/update operation is: if self.cursor.execute("UPDATE `fingerprint` SET documents=CONCAT(documents,%s) WHERE fp=%s",(","+newDocId, thisFP))== 0L: self.cursor.execute("INSERT INTO `fingerprint` VALUES (%s, %s)", (thisFP,newDocId)) The only bottleneck i have observed so far is the query time in mysql. My whole application is web based. So time is a critical factor. I have also thought of using cassandra but have less knowledge of it. Please suggest me a better way to tackle this problem.

  • PHP 'smart' search engine to search Mysql tables advice

    - by Anonymous12345
    I am creating a search engine for my php based website. I need to search a mysql table. Thing is, the search engine must be pretty 'smart', so that users can easily find their items (it's a classifieds website). I have currently set up a FULLTEXT search with this piece of code: MATCH (headline) AGAINST ($querystring) But this isn't enough... For instance, lets say the field headline contains something like Bmw 330ci. If I search for 330, I wont get any results. The ending ('ci') is just one of many endings in car models which must be taken into account when searching the table. Or what if the headline field is bmw330? Also no results, because it only matches full words. Or also, what if the headline is bmw 330, and I search for bmw 520, still with FULLTEXT I will get the bmw 330 as a result, even though I searched for bmw 520... Not good! How should I solve this problem?

  • Truncating a string while storing it in an array in c

    - by Nick
    I am trying to create an array of 20 character strings with a maximum of 17 characters that are obtained from a file named "words.dat". After that the program should truncate the string only showing the first 17 characters and completely ignore the rest of that string. However My question is: I am not quite sure how to accomplish this, can anyone give me some insight on how to accomplish this task? Here is my current code as is: #include <stdio.h> #include <stdlib.h> #define WORDS 20 #define LENGTH 18 char function1(char[WORDS][LENGTH]); int main( void ) { char word_array [WORDS] [LENGTH]; function1(word_array); return ( 0 ) ; } char function1(char word_array[WORDS][LENGTH]) { FILE *wordsfile = fopen("words.dat", "r"); int i = 0; if (wordsfile == NULL) printf("\nwords.dat was not properly opened.\n"); else { for (i = 0; i < WORDS; i++) { fscanf(wordsfile, "%17s", word_array[i]); printf ("%s \n", word_array[i]); } fclose(wordsfile); } return (word_array[WORDS][LENGTH]); } words.dat file: Ninja DragonsFury failninja dragonsrage leagueoflegendssurfgthyjnu white black red green yellow green leagueoflegendssughjkuj dragonsfury Sword sodas tiger snakes Swords Snakes sage Sample output: blahblah@fang:~>a.out Ninja DragonsFury failninja dragonsrage leagueoflegendssu rfgthyjnu white black red green yellow green leagueoflegendssu ghjkuj dragonsfury Sword sodas tiger snakes Swords blahblah@fang:~> What will be accomplished afterwards with this program is: After function1 works properly I will then create a second function name "function2" that will look throughout the array for matching pairs of words that match "EXACTLY" including case . After I will create a third function that displays the 20 character strings from the words.dat file that I previously created and the matching words.

  • parse.json of authenticated play request

    - by niklassaers
    I've set up authentication in my application like this, always allow when a username is supplied and the API-key is 123: object Auth { def IsAuthenticated(block: => String => Request[AnyContent] => Result) = { Security.Authenticated(RetrieveUser, HandleUnauthorized) { user => Action { request => block(user)(request) } } } def RetrieveUser(request: RequestHeader) = { val auth = new String(base64Decode(request.headers.get("AUTHORIZATION").get.replaceFirst("Basic", ""))) val split = auth.split(":") val user = split(0) val pass = split(1) Option(user) } def HandleUnauthorized(request: RequestHeader) = { Results.Forbidden } def APIKey(apiKey: String)(f: => String => Request[AnyContent] => Result) = IsAuthenticated { user => request => if(apiKey == "123") f(user)(request) else Results.Forbidden } } I want then to define a method in my controller (testOut in this case) that uses the request as application/json only. Now, before I added authentication, I'd say "def testOut = Action(parse.json) {...}", but now that I'm using authentication, how can I add parse.json in to the mix and make this work? def testOut = Auth.APIKey("123") { username => implicit request => var props:Map[String, JsValue] = Map[String, JsValue]() request.body match { case JsObject(fields) => { props = fields.toMap } case _ => {} // Ok("received something else: " + request.body + '\n') } if(!props.contains("UUID")) props.+("UUID" -> UniqueIdGenerator.uuid) if (!props.contains("entity")) props.+("entity" -> "unset") props.+("username" -> username) Ok(props.toString) } As a bonus question, why is only UUID added to the props map, not entity and username? Sorry about the noob factor, I'm trying to learn Scala and Play at the same time. :-) Cheers Nik

  • Using LINQ to map dynamically (or construct projections)

    - by CodeGrue
    I know I can map two object types with LINQ using a projection as so: var destModel = from m in sourceModel select new DestModelType {A = m.A, C = m.C, E = m.E} where class SourceModelType { string A {get; set;} string B {get; set;} string C {get; set;} string D {get; set;} string E {get; set;} } class DestModelType { string A {get; set;} string C {get; set;} string E {get; set;} } But what if I want to make something like a generic to do this, where I don't know specifically the two types I am dealing with. So it would walk the "Dest" type and match with the matching "Source" types.. is this possible? Also, to achieve deferred execution, I would want it just to return an IQueryable. For example: public IQueryable<TDest> ProjectionMap<TSource, TDest>(IQueryable<TSource> sourceModel) { // dynamically build the LINQ projection based on the properties in TDest // return the IQueryable containing the constructed projection } I know this is challenging, but I hope not impossible, because it will save me a bunch of explicit mapping work between models and viewmodels.

I'm trying to put image from db to be cached on client side To render image I use ( http://struts.apache.org/2.x/docs/how-can-we-display-dynamic-or-static-images-that-can-be-provided-as-an-array-of-bytes.html ) where special result type render as follow: public void execute(ActionInvocation invocation) throws Exception { ...//some preparation HttpServletResponse response = ServletActionContext.getResponse(); HttpServletRequest request = ServletActionContext.getRequest(); ServletOutputStream os = response.getOutputStream(); try { byte[] imageBytes = action.getImage(); response.setContentType("image/gif"); response.setContentLength(imageBytes.length); //I want cache up to 10 min Date future = new Date(((new Date()).getTime() + 1000 * 10*60l)); ; response.addDateHeader("Expires", future.getTime()); response.setHeader("Cache-Control", "max-age=" + 10*60 + ""); response.addHeader("cache-Control", "public"); response.setHeader("ETag", request.getRequestURI()); os.write(imageBytes); } catch(Exception e) { response.sendError(HttpServletResponse.SC_NOT_FOUND); } os.flush(); os.close(); } But when image is embedded to page it is always reloaded (Firebug shows code 200), and neither Expires, nor max-age are presented in header Host localhost:9090 Accept image/png,image/*;q=0.8,*/*;q=0.5 Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 300 Connection keep-alive Referer http://localhost:9090/web/result?matchId=1 Cookie JSESSIONID=4156BEED69CAB0B84D950932AB9EA1AC; If-None-Match /web/_srv/teamcolor Cache-Control max-age=0 I have no idea why it is dissapered, may be problem in url? It is forms with parameter: http://localhost:9090/web/_srv/teamcolor?loginId=3

  • Is it possible to guarantee a unique id for multiple items using the same id variable at a point in

    - by Scarface
    First of all, do not be overwhelmed by the long code, I just put it for reference...I have a function that preg_replaces content and puts it in a jquery dialog box with a matching open-link. For example, if there is a paragraph with two matches, they will be put inside two divs, and a jquery dialog function will be echoed twice; one for each div. While this works for one match, if there are multiple matches, it does not. I am not sure how to distribute unique ids at a point in time for each of the divs and matching dialog open-scripts. Keep in mind, I removed the preg replace function since it kind of complicates the problem. If anyone has any ideas, they will be greatly appreciated. <?php $id=uniqid(); $id2=uniqid(); echo "<div id=\"$id2\"> </div>"; ?> $.ui.dialog.defaults.bgiframe = true; $(function() { $("<?php echo"#$id2"; ?>").dialog({hide: 'clip', modal: true ,width: 600,height: 350,position: 'center', show: 'clip',stack: true,title: 'title', minHeight: 25, minWidth: 100, autoOpen: false}); $('<?php echo"#$id"; ?>').click(function() { $('<?php echo"#$id2"; ?>').dialog('open'); }) .hover( function(){ $(this).addClass("ui-state-hover"); }, function(){ $(this).removeClass("ui-state-hover"); } ).mousedown(function(){ $(this).addClass("ui-state-active"); }) .mouseup(function(){ $(this).removeClass("ui-state-active"); }); });

  • Project euler problem 3 in haskell

    - by shk
    I'm new in Haskell and try to solve 3 problem from http://projecteuler.net/. The prime factors of 13195 are 5, 7, 13 and 29. What is the largest prime factor of the number 600851475143 ? My solution: import Data.List getD :: Int -> Int getD x = -- find deviders let deriveList = filter (\y -> (x `mod` y) == 0) [1 .. x] filteredList = filter isSimpleNumber deriveList in maximum filteredList -- Check is nmber simple isSimpleNumber :: Int -> Bool isSimpleNumber x = let deriveList = map (\y -> (x `mod` y)) [1 .. x] filterLength = length ( filter (\z -> z == 0) deriveList) in case filterLength of 2 -> True _ -> False I try to run for example: getD 13195 > 29 But when i try: getD 600851475143 I get error Exception: Prelude.maximum: empty list Why? Thank you @Barry Brown, I think i must use: getD :: Integer -> Integer But i get error: Couldn't match expected type `Int' with actual type `Integer' Expected type: [Int] Actual type: [Integer] In the second argument of `filter', namely `deriveList' In the expression: filter isSimpleNumber deriveList Thank you.
