  • Getting useful emails from Hudson instead of tail of ant log

    - by Rick
    A team member of mine recently setup some Hudson continuous-integration builds for a number of our development code bases. It uses the built in ant integration configured in simple way. While, it is very helpful and I recommend it strongly, I was wondering how to get more more concise/informative/useful emails instead of just the tail of the ant build log. E.G., Don't want this: > [...truncated 36530 lines...] > [junit] Tests run: 32, Failures: 0, Errors: 0, Time elapsed: 0.002 sec ... (hundred of lines omitted) ... > [junit] Tests run: 10, Failures: 0, Errors: 0, Time elapsed: 0.001 sec > [junit] Tests FAILED > > BUILD FAILED I assume, that I could skip the build-in ant support and send the build log through a grep script, but I was hoping there was a more integrated or elegant option.

  • ruby-debug19: Can't get working with Ruby 1.9.1p376

    - by tk-421
    Hello, I'm trying to use ruby-debug19 with Ruby 1.9.1p376 but am getting the following error: test.rb:2:in `require': no such file to load -- ruby-debug19 (LoadError) from test.rb:2:in `<main>' Here's test.rb: require 'rubygems' require 'ruby-debug19' Here's the output of "gem list": *** LOCAL GEMS *** ruby-debug19 (0.11.6) (etc.) So running "ruby test.rb" generates the above error. Am I doing this wrong? I thought this was the correct way to run ruby-debug19 (by including the gem and adding "debugger" statements) and haven't been able to find any articles/posts with the same problem. I am using RVM but the above output is all under the same version of Ruby ("ruby -v" shows 1.9.1p376 as expected, and the gem list output is specific to that version and not the OS X system-installed version 1.8.7).

  • MySQL differences between to select queries

    - by bpmccain
    I have two mysql queries that return a column of phone numbers. I want am trying to end up with a list of phone numbers that are in one list, but not in the other. So the two queries I have are: SELECT phone FROM civicrm_phone phone LEFT JOIN civicrm_participant participant ON phone.contact_id = participant.contact_id WHERE phone.is_primary = 1 AND participant.id IS NULL and SELECT phone FROM civicrm_phone phone LEFT JOIN civicrm_participant participant ON phone.contact_id = participant.contact_id WHERE phone.is_primary = 1 AND participant.id IS NOT NULL And before anyone asks, the above two queries do not provide mutually exclusive results (based on using IS NULL and IS NOT NULL for the last WHERE statement), since we have related individuals in the database who use the same phone number, but do not necessarily all have a participant.id. Thanks for any help.

  • How to style alternating rows in asp.net mvc

    - by YeahStu
    I am using a <% foreach ...% loop to list a collection of items on my website. I want to add a different background color for the style of alternating rows in my list. I have found a way to do this but I am not satisfied with it as it seems like a hack. Here is what I have done to solve it so far: <table> <% int counter = 0; foreach (var item in Model) { counter++; if (counter % 2 == 0) { %> <tr class="colorfull"> <% } else { %> <tr> <% } %> ... Is there a best practice that I am missing that people are using for this scenario in ASP.NET MVC?

  • Undefined Results in jQuery Autocomplete

    - by CreativeNotice
    So I've got the latest versions of jQuery and UI running. I'm using the basic autocomplete invocation and returning valid JSON (validated via JSONLint). $("input#cust_id").autocomplete({ source: yoda.app.base + "/assets/cfc/util/autocomplete.cfc?method=cust", minLength: 2, select: function(event, ui) { log(ui.item ? ("Selected: " + ui.item.value + " aka " + ui.item.id) : "Nothing selected, input was " + this.value); } }); Both the value and label elements of the returned array show up in the list as undefined. I can watch the results returned via Firebug and the JSON is correct there as well. Also, while the list only says "undefined" it does say that the same number of times as records returned in JSON. [{"VALUE":"custid1","LABEL":"My Customer Name 1"},{"VALUE":"custname2","LABEL":"My customer name 2"}]

  • Remove linebreak at specific position in textfile

    - by williamx
    I have a large textfile, which has linebreaks at column 80 due to console width. Many of the lines in the textfile are not 80 characters long, and are not affected by the linebreak. In pseudocode, this is what I want: Iterate through lines in file If line matches this regex pattern: ^(.{80})\n(.+) Replace this line with a new string consisting of match.group(1) and match.group(2). Just remove the linebreak from this line. If line doesn't match the regex, skip! Maybe I don't need regex to do this?

  • Python "Every Other Element" Idiom

    - by Matt Luongo
    Hey guys, I feel like I spend a lot of time writing code in Python, but not enough time creating Pythonic code. Recently I ran into a funny little problem that I thought might have an easy, idiomatic solution. Paraphrasing the original, I needed to collect every sequential pair in a list. For example, given the list [1,2,3,4,5,6], I wanted to compute [(1,2),(3,4),(5,6)]. I came up with a quick solution at the time that looked like translated Java. Revisiting the question, the best I could do was l = [1,2,3,4,5,6] [(l[2*x],l[2*x+1]) for x in range(len(l)/2)] which has the side effect of tossing out the last number in the case that the length isn't even. Is there a more idiomatic approach that I'm missing, or is this the best I'm going to get?

  • luntbuild + maven + findbugs = OutOfMemoryException

    - by Johannes
    Hi, I've been trying to get Luntbuild to generate and publish a project site for our project including a Findbugs report. All other reports (Cobertura, Surefire, JavaDoc, Dashboard) work fine, but Findbugs bails out with an OutOfMemoryException. Excluding findbugs from report generation fixes the build --- although obviously without a Findbugs report. The funny thing is that I first encountered this problem locally and solved it by setting MAVEN_OPTS=-Xmx512m. This does not seem to be enough in Luntbuild, however: setting that exact same option as an environment variable of my builder doesn't make a difference. I've found a couple of posts on the 'net stating you should also add -XX:MaxPermSize=512m to MAVEN_OPTS and/or pass -Dmaven.findbugs.jvmargs=-Xmx512m to mvn.bat. None of these (or their combination) seem to help though so any hints would be greatly appreciated!

  • Chinese encoding issue while listing files

    - by Null Pointer
    I am running a Java application on a Solaris10 with Chinese. Now there are some files in a directory with chinese filenames. When I do files = new File(dir).list() where "dir" is the parent directory containing that chinese file, I get the result filename files[0] as ?????(some junk characters). Now the deal is that my programs file.encoding property is already set to GBK and I also do Charset.isSupported("GBK") and it returns true too. So where could be the problem. I am running out of ideas. NOTE: I am not trying to print the filename anywhere or copy the file or something. I am simply openeing a stream to it, something like below: files = new File(dir).list(); new FileInputStream(files[0]); Now this gives me a FileNotFoundExcpetion, so I debug just to find that value inside files[0] is "??????".

  • CSS Attribute Content Selector multiple declarations

    - by Dave
    I have this in my CSS: div#headwrap ul li a[href*="dev"] {background: #034769}; div#headwrap ul li a[href*="music"] {background: #A61300}; div#headwrap ul li a[href*="opinion"] {background: #b2d81e}; div#headwrap ul li a[href*="work"] {background: #ffc340}; So, my expected behavior is that where a link (a) within a list item (li) inside a unordered list (ul) inside a div with id "headwrap" has an href that contains "dev", the link will have a background color of #034769. If the link has an href that contains "music" it will have a background color of #A61300, and so on. However, what I am seeing is that the rule is only correctly applied to "dev". If I reorder the CSS declarations (putting music first, for instance), it only gets applied to "music". I'm testing in Firefox and Chrome, both are doing the same thing. Only the first one is applied. Anyone have any ideas why?

  • Adding a sortcomparefunction to Dynamic Data Grid in flex

    - by Tom
    Hi, I am trying to create a dynamic datagrid in Flex 3, I have a list of columns a list of objects which correspond to datapoints for those columns which I fetch from a url. While the grid works perfectly fine the problem is that sorting on the columns is done in lexical order. I am aware that this can be fixed by adding a sortcomparefunction to a column, which is not easy for this case. I have tried doing var dgc:DataGridColumn = new DataGridColumn(dtf); f1[dtf] = function(obj1:Object, obj2:Object):int { return Comparators.sortNumeric(obj1[dtf],obj2[dtf]); }; dgc.sortCompareFunction = f1[dtf];` But the problem is that the function object that I am creating here is being overwritten in every iteration (as I am adding columns) and eventually all the columns will have sorting done only on the last column added. Suggestions please.

  • SPGridView current item in Sharepoint

    - by pistacchio
    Hi, I'm making a custom webpart. I takes some items from a list and display them with a SPGridView. I bound the fields like this: // Grab data from a SP List into dvwTickets SPGridView grdMyTickets = new SPGridView(); grdMyTickets.DataSource = dvwTickets; [..] BoundField colTicketTypology = new BoundField(); colTicketTypology.DataField = "ID"; colTicketTypology.HeaderText = ticketList.Fields.GetFieldByInternalName("ID").Title; grdMyTickets.Columns.Add(colTicketTypology); [..] This works. Now, what a grid does behind the scene when binding data to it is cycling through the binded data. How can I access the "Current Item" to make operations on each item while binding? Thanks

  • CSS Horizontal sub-menu

    - by Develman
    Hello, I am working on a horizontal CSS dropdown menu. It is still working nearly fine for IE 7, IE 8 , Firefox and Chrome. But I want to make the top <ul> to be on top level (e.g. z-index: 100). I want this because the top level <ul> has a graphical background and the dropdown is just styled with css and in the current way it is destroying the layout. HTML Code: <div id="mainMenu"> <ul> <li><a href="t1">TOP1<!--[if gt IE 6]><!--></a><!--<![endif]--> <!--[if lte IE 6]><table><tr><td><![endif]--> <ul> <li><a href="l1">LINK1</a></li> <li><a href="l2">LINK2</a></li> <li><a href="l3">LINK3</a></li> <li><a href="l4">LINK4</a></li> </ul> <!--[if lte IE 6]></td></tr></table></a><![endif]--> </li> <li class="center"><a href="t2">TOP2<!--[if gt IE 6]><!--></a><!--<![endif]--> <!--[if lte IE 6]><table><tr><td></td></tr></table></a><![endif]--></li> <li><a name="t3">TOP3<!--[if gt IE 6]><!--></a><!--<![endif]--> <!--[if lte IE 6]><table><tr><td><![endif]--> <ul class="last"> <li><a href="l5">LINK5</a></li> <li><a href="l6">LINK6</a></li> <li><a href="l7">LINK7</a></li> </ul> <!--[if lte IE 6]></td></tr></table></a><![endif]--> </li> </ul> </div> CSS Code /* style the outer div to give it width */ #mainMenu { position: absolute; margin-left: 6px; margin-top: 180px; } /* remove all the bullets, borders and padding from the default list styling */ #mainMenu ul { position: absolute; width: 494px; padding: 0; margin: 0; list-style-type: none; background: #FFF url(../images/mainMenu_bg.gif) no-repeat; } /* float the list to make it horizontal and a relative positon so that you can control the dropdown menu positon */ #mainMenu li { position: relative; float: left; padding-left: 5px; width: 160px; vertical-align: middle; text-align: left; } #mainMenu li.center { padding-left: 0px; text-align: center; } /* style the links for the top level */ #mainMenu a, #mainMenu a:visited { display: block; font: bold 12px/1em Helvetica, arial, sans-serif; color: #FFF; text-decoration: none; height: 42px; line-height: 35px; } /* hide the sub levels and give them a positon absolute so that they take up no room */ #mainMenu ul ul { visibility: hidden; position: absolute; height: 0; top: 35px; left: -5px; width: 165px; } /* style the table so that it takes no part in the layout - required for IE to work */ #mainMenu table { position: absolute; top: 0; left: 0; } /* style the second level links */ #mainMenu ul ul a, #mainMenu ul ul a:visited { width: 165px; height: 20px; line-height: 19px; font: bold 10px Helvetica, arial, sans-serif; background: #EF7D0E; color: #FFF; text-align: left; padding: 6px 0 0 5px; border-top: 1px solid #C1650B; } #mainMenu ul ul.last a, #mainMenu ul ul.last a:visited { width: 162px; } /* style the top level hover */ #mainMenu a:hover, #mainMenu ul ul a:hover{ color: #FFF; text-decoration: underline; } #mainMenu :hover > a, #mainMenu ul ul :hover > a { color: #FFF; text-decoration: underline; } /* make the second level visible when hover on first level list OR link */ #mainMenu ul li:hover ul, #mainMenu ul a:hover ul{ visibility: visible; } I have still a problem with showing the table in IE 6 but my main problem here is to show the LINK1...6 under the TOP links. I have tried many settings with z-index but nothing worked here. I hope you can help me ;)

  • Populate Multiple PDFs

    - by gmcalab
    I am using itextsharp to populate my PDFs. I have no issues with this. Basically what I am doing is getting the PDF and populating the fields in memory then passing back the MemoryStream to be displayed on a webpage. All this is working with a single document PDF. What I am trying to figure out now, is merging multiple PDFs into one MemoryStream. The part I cant figure out is, the documents I am populating are identical. So for example, I have a List<Person> that contains 5 persons. I want to fill out a PDF for each person and merge them all into one, in memory. Bare in mind I am going to fill out the same type of document for each person. The problem I am getting is that when I try to add a second copy of the same PDF to be filled out for the second iteration, it just overwrites the first populated PDF, since it's the same document, therefore not adding a second copy for the second Person at all. So basically if I had the 5 people, I would end up with a single page with the data of the 5th person, instead of a PDF with 5 like pages that contain the data of each person respectively. Here's some code... MemoryStream ms = ms = new MemoryStream(); PdfReader docReader = null; PdfStamper Stamper = null; List<Person> persons = new List<Person>() { new Person("Larry", "David"), new Person("Dustin", "Byfuglien"), new Person("Patrick", "Kane"), new Person("Johnathan", "Toews"), new Person("Marian", "Hossa") }; try { // Iterate thru all persons and populate a PDF for each foreach(var person in persons){ PdfCopyFields Copier = new PdfCopyFields(ms); Copier.AddDocument(GetReader("Person.pdf")); Copier.Close(); docReader = new PdfReader(ms.ToArray()); Stamper = new PdfStamper(docReader, ms); AcroFields Fields = Stamper.AcroFields; Fields.SetField("FirstName", person.FirstName); } }catch(Exception e){ // handle error }finally{ if (Stamper != null) { Stamper.Close(); } if (docReader != null) { docReader.Close(); } }

  • Alpha Beta Search

    - by Becky
    I'm making a version of Martian Chess in java with AI and so far I THINK my move searching is semi-working, it seems to work alright for some depths but if I use a depth of 3 it returns a move for the opposite side...now the game is a bit weird because when a piece crosses half of the board, it becomes property of the other player so I think this is part of the problem. I'd be really greatful if someone could look over my code and point out any errors you think are there!

  • Scheme early "short circuit return"?

    - by Suan
    I'm trying to find out how I can do an "early return" in a scheme procedure without using a top-level if or cond like construct. (define (win b) (let* ((test (first (first b))) (result (every (lambda (i) (= (list-ref (list-ref b i) i) test)) (enumerate (length b))))) (when (and (not (= test 0)) result) test)) 0) For example, in the code above, I want win to return test if the when condition is met, otherwise return 0. However, what happens is that the procedure will always return 0, regardless of the result of the when condition. The reason I am structuring my code this way is because in this procedure I need to do numerous complex checks (multiple blocks similar to the let* in the example) and putting everything in a big cond would be very unwieldy.

  • Copy hashtable to another hashtable using c++

    - by zengr
    I am starting with c++ and need to know, what should be the approach to copy one hashtable to another hashtable in C++? We can easily do this in java using: HashMap copyOfOriginal=new HashMap(original); But what about C++? How should I go about it? UPDATE Well, I am doing it at a very basic level,perhaps the java example was a wrong one to give. This is what I am trying to implement using C++: I have this hash array and each element of the array point to the head of a linked list. Which has it's individual nodes (data and next pointer). And now, I need to copy the complete hash array and the linked list each node is pointing to.

  • Is there built-in method to tell if specific URL belongs to this SPWeb or other SPWeb?

    - by Janis Veinbergs
    Hello. I have a list of urls (content type usage url's). Now, content types are deployed across web's. I need to loop those content types and do some actions in each list, but opening new SPWeb instance every loop is too resource intensive. Is there built-in method to tell me if this URL belongs to certain SPWeb object? Example: SPWeb's may be http://server/web1 http://server/web2 http://server/web2/subweb1 http://server/web2/subweb2 With content type usage links like: /web2/Pages /web2/Lists/Tasks /web2/Lists/Documents /web2/subweb1/Lists/Tasks ... As you can see, for first 3 usages i don't need to open up new SPWeb

  • .NET MVC Ajax Form - How do you hide it?

    - by Tommy
    Ok, everything is 'functionally' working with what I am attempting to accomplish and once again, I am sure this is something dumb, but I cannot figure out how to do this one thing. I have an edit form for an entity, lets say a car. This 'car' can have 0 - many passengers. So on my edit form, I have all the fields for the car, then a list view showing each passenger (partial). I also have a 'add new passenger' button that will render a new partial view that allows you to enter a passenger. This has a cancel link and an add button to submit an Ajax form. When you add a passenger, the passenger is automatically added to the list, but I need the enter passenger form to go away. I have tried using the onSuccess and onComplete functions to hide the div that the form is in, but both render just the partial view HTML elements (white screen, text) and not the partialView in the context of the entire page. Sources: 1) Main Edit View <script type="text/javascript"> Function hideForm(){ document.getElementById('newPassenger').style.display = 'none'; } </script> <h2>Edit</h2> <%-- The following line works around an ASP.NET compiler warning --%> <%= ""%> <%Html.RenderPartial("EditCar", Model)%> <h2>Passengers for this car</h2> <%=Ajax.ActionLink("Add New Passenger", "AddPassenger", New With {.ID = Model.carID}, New AjaxOptions With {.UpdateTargetId = "newPassenger", .InsertionMode = InsertionMode.Replace})%> <div id="newPassenger"></div> <div id="passengerList"> <%Html.RenderPartial("passengerList", Model.Passengers)%> </div> <div> <%= Html.ActionLink("Back to List", "Index") %> </div> 2) AddPassenger View. The cancel link below is an action that returns nothing, thus removing the information in the div. <% Using Ajax.BeginForm("AddPassengerToCar", New With {.id = ViewData("carID")}, New AjaxOptions With {.UpdateTargetId = "passengerList", .InsertionMode = InsertionMode.Replace})%> <%=Html.DropDownList("Passengers")%> <input type="submit" value="Add" /> <%=Ajax.ActionLink("Cancel", "CancelAddControl", _ New AjaxOptions With {.UpdateTargetId = "newPassenger", .InsertionMode = InsertionMode.Replace})%><% end using %>

  • Stack overflow in OCaml and F# but not in Haskell

    - by Fernand Pajot
    I've been comparing for fun different languages for speed in execution of the following program: for i from 1 to 1000000 sum the product i*(sqrt i) One of my implementations (not the only one) is constructing a list [1..1000000] and then folding with a specific funtion. The program works fine and fast in Haskell (even when using foldl and not foldl') but stack overflows in OCaml and F#. Here is the Haskell code: test = foldl (\ a b -> a + b * (sqrt b)) 0 create 0 = [] create n = n:(create (n-1)) main = print (test (create 1000000)) And here is the OCaml one: let test = List.fold_left (fun a b -> a +. (float_of_int b) *. (sqrt (float_of_int b))) 0. ;; let rec create = function | 0 -> [] | n -> n::(create (n-1)) ;; print_float (test (create 1000000));; Why does the OCaml/F# implementation stack overflows?

  • Is it possible to interop with Thunderbird using C#?

    - by Jurily
    Here's the latest hurdle in my ongoing quest to automate my job: All email in the company goes through 4 different email adresses, switching randomly back and forth (with a note attached in the global share: please set "keep email on server") All logic related to email is contained in a nice big Thunderbird profile, which gets copied back and forth to new machines; this includes sorting invoices into 5 different "folders", the list of VIP adresses to send notifications, and the VIP level of those customers I only need the contents of those folders (the attachments, anyway) The question: is there a way to ask Thunderbird for those attachments and lists from C#? Alternatively, can Outlook be set up to synchronize with Thunderbird? Where do I start reading? Ditching Thunderbird is not an option right now, I need to keep up with changes to the VIP list. P.S. I will set up a real email server right after Monkey saves me enough time to convince people about it.

  • Populate InfoPath Combo Box

    - by fwm
    I am trying to populate a drop down and found this page, which provides part of the solution: http://www.bizsupportonline.net/infopath2007/programmatically-fill-populate-drop-down-list-box-infopath-2007.htm I got this to work, but if players.xml was changed, the drop down list didn't reflect it. I had to rename the file and add the new file as my secondary data source to see the change. For my purposes, the xml file that is used to populate the drop down box would need to be created anew. Each time the form is loaded, I programatically create a new xml file, but the drop down doesn't pick up the new file, even though I have named it as the secondary data source. It seems that once you set a file to be your secondary data source, it takes a snapshot of that file at the time the source was added as a secondary data source and if you change the file, you must rename and add it as your secondary source. How do I populate a drop down box from an XML file such that if the XML file changes, the contents of the drop down change accordingly?
