  • What should a Java/SOA developer be able to do?

    - by Regular Joe
    Hello community. I got assigned the task to list the activities a Java Developer should be able to perform and create an estimate about the time it would take. I've came up with the following: S = Small complexity M = Medium complexity H = High complexity 1d = 1 day Create JDBC CRUD backend ( S=1d, M=5d, H=10d ) Create JSP/Servlet frontend for a CRUD app ( S=1d, M=10d, H=20d ) Create Swing desktop frontend ( S=1d, M=15d, H=30d) Create ORM based CRUD ... Create Webapp fronend with webframework ... This is thought for a Java "enterprise" developer. The other profile I have is SOA Developer, but I could not pass beyond: Create webservice ( S=.5d, M=2d, H=7d ) Q.- What other activities should a Java Developer be able to do? Q.- What activities should a SOA Developer be able to do? Please, help me with this, I know this is in the limit of the kind of questions that could be asked here, but I really need a little push on this, and I don't want to go to Yahoo Answers for this.

  • How can I convert HTML to Textile?

    - by Joe Van Dyk
    I'm scraping a static html site and moving the content into a database-backed CMS. I'd like to use Textile in the CMS. Is there a tool out there that converts HTML into Textile, so I can scrape the existing site, convert the HTML to Textile, and insert that data into the database?

  • Tiling rectangles seamlessly in WPF

    - by Joe White
    I want to seamlessly tile a bunch of different-colored Rectangles in WPF. That is, I want to put a bunch of rectangles edge-to-edge, and not have gaps between them. If everything is aligned to pixels, this works fine. But I also want to support arbitrary zoom, and ideally, I don't want to use SnapsToDevicePixels (because it would compromise quality when the image is zoomed way out). But that means my Rectangles sometimes render with gaps. For example: <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Background="Black"> <Canvas SnapsToDevicePixels="False"> <Canvas.RenderTransform> <ScaleTransform ScaleX="0.5" ScaleY="0.5"/> </Canvas.RenderTransform> <Rectangle Canvas.Left="25" Width="100" Height="100" Fill="#CFC"/> <Rectangle Canvas.Left="125" Width="100" Height="100" Fill="#CCF"/> </Canvas> </Page> If the ScaleTransform's ScaleX is 1, then the Rectangles fit together seamlessly. When it's 0.5, there's a dark gray streak between them. I understand why -- the combined semi-transparent edge pixels don't combine to be 100% opaque. But I would like a way to fix it. I could always just make the Rectangles overlap, but I won't always know in advance what patterns they'll be in (this is for a game that will eventually support a map editor). Besides, this would cause artifacts around the overlap area when things were zoomed way in (unless I did bevel-cut angles on the underlapping portion, which is an awful lot of work, and still causes problems at corners). Is there some way I can combine these Rectangles into a single combined "shape" that does render without internal gaps? I've played around with GeometryDrawing, which does exactly that, but then I don't see a way to paint each RectangleGeometry with a different-colored brush. Are there any other ways to get shapes to tile seamlessly under an arbitrary transform, without resorting to SnapsToDevicePixels?

  • To maximize chances of functional programming employment

    - by Rob Agar
    Given that the future of programming is functional, at some point in the nearish future I want to be paid to code in a functional language, preferably Haskell. Assuming I have a firm grasp of the language, plus all the basic programmer attributes (good communication skills/sense of humour/hygiene etc), what should I concentrate on learning to maximize my chances? Are there any particularly sought after libraries I should know? Alternatively, would another language be a better bet, say F#? (I'm not too fussed about the kind of programming work, so long as it's reasonably interesting and reasonably well paid, and with nice people)

  • PHP - Rotate a HEX color value (eg swap all colors with "next" hex)

    - by Joe
    I have a set of hex values in an array in PHP. On my page, I have a slider which the user can "slide" to return a value between 1-100. I want to then, based on this slider value, swap all the colors in the array based on the colors "next" color based on the position in the array. An example of the same sort of thing would be like in photshop where you can rotate the hue of a layer. I want to do the same thing, in PHP, for a hex value. Any clues?

  • Symfony sfDoctrineGuard plugin sfGuardUser module

    - by Joe Mc
    When using sfDoctrineGuard plugin, it automatically generates the backend administration functionality where I can edit users of the system and assign them permissions. So I visit http://.../backend_dev.php/sf_guard_user/:id/edit where I am presented with the user's information including the available permissions to select. By default the permissions are shown as a multiple select box, HTML follows: <select name="sf_guard_user[permissions_list][]" multiple="multiple" id="sf_guard_user_permissions_list"> <option value="1">Permission1</option> <option value="2">Permission2</option> <option value="3">Permission3</option> <option value="4">Permission4</option> </select> What I would prefer is a list of checkboxes. So I searched around and found that if I add the option "expanded" set to true to the following code: 'permissions_list' => new sfWidgetFormDoctrineChoice(array('multiple' => true, 'model' => 'sfGuardPermission', 'expanded' => true,)), The code is part of this file: lib/form/doctrine/sfDoctrineGuardPlugin/base/BasesfGuardUserForm.class.php. I don't think I should've edited this file (potential for changes to be overwritten should sfDoctrineGuard ever be re-installed) but couldn't think of another way to make it work. The generated HTML is as follows: <ul class="checkbox_list"> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="1" id="sf_guard_user_permissions_list_1" />&nbsp;<label for="sf_guard_user_permissions_list_1">Permission1</label></li> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="2" id="sf_guard_user_permissions_list_2" />&nbsp;<label for="sf_guard_user_permissions_list_2">Permission2</label></li> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="3" id="sf_guard_user_permissions_list_3" />&nbsp;<label for="sf_guard_user_permissions_list_3">Permission3</label></li> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="4" id="sf_guard_user_permissions_list_4" />&nbsp;<label for="sf_guard_user_permissions_list_4">Permission4</label></li> </ul> What I need to do now is split up the permissions based on their prefix. For example if I had permissions named user_action1, user_action2, file_action1, file_action2, they would display like: User checkbox (custom label) Action One checkbox Action Two File checkbox (custom label) Action One checkbox Action Two but have no idea where to start with this. It would be easy if there was a template to edit but since I'm dealing with the Forms framework it is my understanding that the templates are generated on the fly - I can see them in my symonfy cache folder. How would I go about this? I started writing my own sfWidgetFormDoctrineChoicePermission class that extends the same class as sfWidgetFormDoctrineChoice but am struggling to edit the rendering functions correctly for the desired output. Is this the correct way to go about this work? I also need to integrate my sfGuardUserProfile model into the edit user page (same as above), I read somwhere that editing the generator.yml file for the sfGuardUser plugin module and simply adding the field names from the sfGuardUserProfile table would make it work, but sadly it doesn't. Any help with any of my queries would be appreciated. Thanks

  • Database vs Networking

    - by user16258
    I have completed my diploma in (IT) and now pursuing degree, i am in last semester of my B.E(I.T). I want to do specialization either in Database(oracle) or in Networking(cisco). Which one of two will be in more demand in near future, i know it's all about interest but still i would like to know your opinion. Most of people say that a network engineer is never paid as better as a programmer or a DBA, and few says they do get paid well. What would be the scope if i clear my CCNA and CCNP exams, or either OCA & OCP exams, what would be more rewarding. Also i have read somewhere that most of the task of DBA will be automated so in future demand of a DBA will reduce. I would also like to hear from Network engineers what's the scenario out there in India. Thanks

  • ActiveMQ broker configuration error when specifying persistenceAdapter: "One of '{WC[##other:"http:/

    - by Joe
    I am setting up a simple ActiveMQ embedded broker. It works fine, until I try to configure a persistence adapter. I am basically just copying the configuration from http://activemq.apache.org/persistence.html#Persistence-ConfiguringKahaPersistence. When I add this configuration to my Spring configuration, like so: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:amq="http://activemq.apache.org/schema/core" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core-5.3.0.xsd"> <amq:broker useJmx="true" persistent="true" brokerName="localhost"> <amq:transportConnectors> <amq:transportConnector name="vm" uri="vm://localhost"/> </amq:transportConnectors> <amq:persistenceAdapter> <amq:kahaPersistenceAdapter directory="activemq-data" maxDataFileLength="33554432"/> </amq:persistenceAdapter> </amq:broker> </beans> I get the error: cvc-complex-type.2.4.a: Invalid content was found starting with element 'amq:persistenceAdapter'. One of '{WC[##other:"http://activemq.apache.org/schema/core"]}' is expected. When I take out the amq:persistenceAdapter element, it works fine. The same error happens no matter which persistence adapter I include in the body, e.g. jdbc, journal, etc. Any help would be greatly appreciated. Thanks.

  • Algorithm for digit summing?

    - by Joe
    I'm searching for an algorithm for Digit summing. Let me outline the basic principle: Say you have a number: 18268. 1 + 8 + 2 + 6 + 8 = 25 2 + 5 = 7 And 7 is our final number. It's basically adding each number of the whole number until we get down to a single (also known as a 'core') digit. It's often used by numerologists. I'm searching for an algorithm (doesn't have to be language in-specific) for this. I have searched Google for the last hour with terms such as digit sum algorithm and whatnot but got no suitable results. Any help would be great, thanks.

  • iPhone sdk Cocoa Touch - Pass touches down from parent UIView to child UIScrollview

    - by Joe
    I have a UIView inside my xib in IB and inside that is a UIScrollview that is a small 80x80 square and dynamically loaded with 8 or so 80 x 80 thumbnail images. The UIScrollview is not clipping the images so that they extend out either side so you can swipe left and right to scroll a chosen image into the the centre, paging is on so they snap ti each image. I have researched and found this is the best and possibly only way to do this. The UIScrollview sits in a 'container' UIView for one reason, it is there to receive the touches/swipes and pass them down to it's child the UIScrollview as otherwise all touches would have to start in the small 80x80 UIScrollview area and I wan them to be anywhere along the row of images. I have seen some sample code somewhere for doing this but just can not implement it. Treat me as a noob, starting from beginning to end, how should the UIView and UIScrollview be set up in IB to allow any touches to be passed, and what code should I put into where? The UIView is set up as scroll_container and the child UIScrollview is char_scroll At the moment I have got it all working except for the touches being passed from the parent to the child, and at the moment the touches have to always start inside the UIScrollview (tiny 80x80 box in centre) when I want to be able to swipe left or right in the long 480X80 horizontal parent UIView and have this still scroll the child UIScrollview. Hope you can help and understand what I mean!

  • ruby Test::Unit Command line options?

    - by Joe Soul-bringer
    Hi all, When running tests in Ruby's unit::test framework, is there a really easy way to specify, from the command-line, that only one test should be run (that is, specify the test class and test member variable)? If not, is there another framework that has this feature?

  • Text encoding in HTML text fields

    - by joe
    I have a site up that has a form on it. The form POSTs to a php script which then inserts the data into my database. The page has a charset=UTF-8 attribute in the <meta> tag, and the database is setup to use UTF-8. However, when I copy and paste characters from MS Word into the field, the output is messed up. For example, the quotes in I am using "Microsoft Word" '''' become I am using “Microsoft Word†???? in the database. Anyone have any idea why this might occur?

  • What Is The Proper Location For One-Offs In VCS Repos?

    - by Joe Clark
    I have recently started using Mercurial as our VCS. Over the years, I have used RCS, CVS, and - for the last 5 years - SVN. Back 13 years ago, when I primarily used CVS and RCS, large projects went into CVS and one-offs were edited in place on the specific server and stored in RCS. This worked well as the one-offs were usually specific to the server and the servers were backed up nightly. Jump forward a decade and a lot of the one-off scripts became less centralized - they might be needed on any server at some random time. This was also OK, because now I was a begrudging SVN user. Everything (except for docs) got dumped into one repo. Jump to 2010. Now I am using Mercurial and am putting large projects in their own repo again. But what to do with the one-offs? The options as I see them: A repo for each script. It seems a bit cluttered to create a repo for every one page script that might get ran once a year. RCS Not an option. There are many possible servers that might need a specific script. Continuing to use SVN just for one-offs. No. There no advantage I see over the next option. Create a repo in Mercurial named "one-offs". This seems the most workable. The last option seems the best to me - however; is there a best practice regarding this? You also might be wondering if these scripts are truly one-offs if they will be reused. Some of them may be reused 6 months or a year from now - some, never. However, nearly all of them involve several man-hours of work due to either complex logic or extensive error checking. Simply discarding them is not efficient.

  • Visual Studio 2005 "Add Web Deployment Project..." not showing up for web application projects.

    - by Joe Sands
    I downloaded the Web Deployment Project plug-in for Visual Studio 2005. I installed it. I have a project that I am working on that is a Web Application Project. The Add Web Deployment Project Build menu selection is not in the Build Menu or Solution Explorer. If I create a raw test Web Site Project, the menu item magically appears. Is this by design or am I missing something. Also, I am completely up to date on all the VS 2005 updates.

  • linq Except and custom IEqualityComparer

    - by Joe
    I'm trying to implement a custom comparer on two lists of strings and use the .Except() linq method to get those that aren't one one of the lists. The reason I'm doing a custom comparer is because I need to do a "fuzzy" compare, i.e. one string on one list could be embedded inside a string on the other list. I've made the following comparer ` public class ItemFuzzyMatchComparer : IEqualityComparer { bool IEqualityComparer<string>.Equals(string x, string y) { return (x.Contains(y) || y.Contains(x)); } int IEqualityComparer<string>.GetHashCode(string obj) { if (Object.ReferenceEquals(obj, null)) return 0; return obj.GetHashCode(); } } ` When I debug, the only breakpoint that hits is in the GetHashCode() method. The Equals() never gets touched. Any ideas?

  • Best hardware for a Ubuntu Computer?

    - by Dante Ashton
    Hey all. I'll be needing a new PC soon, but I've decided to build my own, so my question is...what's the best hardware for Ubuntu? Specifically, in terms of graphics cards; I'm looking for something that will run smoothly (for Compiz's effects and Unity) but will be quite modern (IE: have a HDMI output) The machine itself is just a generic computer, nothing special; I just want to future-proof it. I'm looking at quad-core chips and 3-4 gig of RAM. I want something that will play nice with Ubuntu; now, and in the future... I used to build machines years ago, but I've fallen behind (that was in the Windows 98 era...so yeah, quite a while ago!) My main problem is the graphics card; I'd prefer to stick with NVIDIA, but only a tiny amount of computers I've seen play nice with Nouveau.

  • Actionscript 3.0 - drag and throw with easing

    - by Joe Hamilton
    I'm creating a map in flash and I would like to have a smooth movement similar to this: http://www.conceptm.nl/ I have made a start but I'm having trouble taking it to the next stage. My code currently throws the movieclip after the mouse is release but there is no easing while the mouse button is down. Any tips on how I would achieve this? Here is my current code: // Vars var previousPostionX:Number; var previousPostionY:Number; var throwSpeedX:Number; var throwSpeedY:Number; var isItDown:Boolean; // Event Listeners addEventListener(MouseEvent.MOUSE_DOWN, clicked); addEventListener(MouseEvent.MOUSE_UP, released); // Event Handlers function clicked(theEvent:Event) { isItDown =true; addEventListener(Event.ENTER_FRAME, updateView); } function released(theEvent:Event) { isItDown =false; } function updateView(theEvent:Event) { if (isItDown==true){ throwSpeedX = mouseX - previousPostionX; throwSpeedY = mouseY - previousPostionY; mcTestMovieClip.x = mouseX; mcTestMovieClip.y = mouseY; } else{ mcTestMovieClip.x += throwSpeedX; mcTestMovieClip.y += throwSpeedY; throwSpeedX *=0.9; throwSpeedY *=0.9; } previousPostionX= mcTestMovieClip.x; previousPostionY= mcTestMovieClip.y; }

  • 'Invalid column name [ColumnName]' on a nested linq query.

    - by Joe
    I've got the following query: ATable .GroupBy(x=> new {FieldA = x.FieldAID, FieldB = x.FieldBID, FieldC = x.FieldCID}) .Select(x=>new {FieldA = x.Key.FieldA, ..., last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault().Timestamp}) results in: SqlException: Invalid column name 'FieldAID' x 5 SqlException: Invalid column name 'FieldBID' x 5 SqlException: Invalid column name 'FieldCID' x 1 I've worked out it has to do with the last query to Timestamp because this works: ATable .GroupBy(x=> new {FieldA = x.FieldAID, FieldB = x.FieldBID, FieldC = x.FieldCID}) .Select(x=>new {FieldA = x.Key.FieldA, ..., last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault()}) The query has been simplified. The purpose is to group by a set of variables and then show the last time this grouping occured in the db. I'm using Linqpad 4 to generate these results so the Timestamp gives me a string whereas FirstOrDefault gives me the whole object which isn't ideal. Update On further testing I've noticed that the number and type of SQLException is related to the class created in the groupby clause. So, ATable .GroupBy(x=> new {FieldA = x.FieldAID}) .Select(x=>new {FieldA = x.Key.FieldA, last_seen = x.OrderByDescending(y=>y.Timestamp).FirstOrDefault()}) results in SqlException: Invalid column name 'FieldAID' x 5
