• Manage groups of build configurations in Hudson

  - by Lóránt Pintér

  I'm using Hudson to build my application. I have several branches that come and go. Whenever there's a new branch, I have to set up the following builds for it: a continuous build that runs after every change in SVN a nightly build a nightly site generation (I'm using Maven under the hood) and a weekly integration build for some branches currently this means I need to copy four template configurations and set them up with the branch URL. I don't like this for two reasons: It's redundant, so modifying something is error-prone and takes a lot of time. I need four full checkouts of the product per branch on every build slave, plus four separate private Maven repository, not to mention the built artifacts. This is a lot of space wasted. What I'd like instead is to have one workspace and one configuration for allthese builds. Is this possible with Hudson?

• Coldfusion CFC creation taking a variable amout of time to execute.

  - by Bazza

  I've been doing some logging of object creation times in our open account process in production. Periodically, initializing an object would take way longer than expected. By initializing I mean calling it's init() and passing a couple of arguments that may be simple variables or objects. e.g. <cfset validateObj = createObject("component", "compExample").init( productionMode = VARIABLES.productionMode, ipWhiteListed = isWhiteListed, ipLocatorObj = VARIABLES.ipLocatorObj ) /> Thats all that happens in init() methods. Generally the execution time would be 0ms, but at random times I might get 3 or 3.5 seconds. This is not specific to one particular server or to our generally busy period. It appears to be quite random. One thought was that these templates were being evicted from our template cache as they are not especially frequently used, although I checked cfstat on a number of servers and the max CP/Sec is -1. Running CF 8,0,1 Has anybody else ever come across this?

• Resources for dashboard app backend design

  - by Nix

  I am looking for examples of code/data/infrastructure design for a dashboard-style webapp. I am designing an interface for staff and faculty at a university to access departmental resources and be alerted of cyclical processes, events, deadlines, etc. Technologies I am working with: apache tomcat 6 and a mySQL database, JSP (including JSTL), bootstrap 3, and javascript/jquery. I have basic experience most of these technologies building smaller web apps but was hoping someone could direct me towards a book or other resource that discusses how to design the db architecture (and maybe how to template) for a dashboard, esp. for something like a notification systems. Any suggestions?

• Most efficient way to fetch and output Content with 2-Level Comments?

  - by awegawef

  I have some content with up to 2-levels of replies. I am wondering what the most efficient way to fetch and output the replies. I should note that I am planning on storing the comments with fields content_id and reply_to, where reply_to refers to which comment it is in reply to (if any). Any criticism on this design is welcome. In pseudo-code (ish), my first attempt would be: # in outputting content CONTENT_ID all_comments = fetch all comments where content_id == CONTENT_ID root_comments = filter all_comments with reply_to == None children_comments = filter all_comments with reply_to != None output_comments = list() for each root_comment children = filter children_comments, reply_to == root_comment.id output_coments.append( (root_comment, children) ) send output_comments to template Is this the best way to do this? Thanks in advance. Edit: On second thought, I'll want to preserve date-order on the comments, so I'll have to do this a bit differently, or at least just sort the comments afterward.

• CompareValidator works in listview's editItemTemplate but not in insertitemtemplate

  - by Sam

  Hi, I have a validation problem I have a listview, in the edit item template I have two composite controls with a textbox inside I put a comparevalidator on it <asp:CompareValidator ID="myCompareValidator" runat="server" ControlToValidate="mycompositecontrol1" ControlToCompare="mycompositecontrol2" Operator="GreaterThanEqual" Type="Date" Display="Dynamic" ErrorMessage="there is an error !"

If you know that problem, help me please thanks in advance

• Forcing a templated object to construct from a pointer

  - by SalamiArmi

  I have a fictional class: template<typename T> class demonstration { public: demonstration(){} ... T *m_data; } At some point in the program's execution, I want to set m_data to a big block of allocated memory and construct an object T there. At the moment, I've been using this code: void construct() { *m_data = T(); } Which I've now realised is probably not the best idea... wont work under certain cirumstances, if T has a private assignment operator for example. Is there a normal/better way to do what I'm attempting here?

• Service for converting SWFs with ActionScript to Video (MPEG, AVI, or MOV)

  - by pcooley

  The SWF files generated by our application are a basic template that reference external resources (images, and textual data) that actionscript uses to fuel the display. Thus the SWF is responsible for the creative layout of the screen the flash player. It is the results of this actions script, images, and textual data that need to be converted to a video format. Is anyone familiar with an online service that would be able to convert such .swf files that our site generates to a video format (say .avi, .mpeg, .mov). Or an application? Note: A more common case might be the conversion of an embedded FLV to a video, but this is not our need

• Spring + Hibernate session management

  - by toc777

  I have been reading about using Spring with Hibernate and I am really confused about session management. Hopefully someone can clear a few things up for me, First of all I have no idea how sessions are managed when using HibernateTemplate. Is a session opened and closed when you call a method Eg Save() on the template? When you use the find() method, are detached objects returned? I have read the Spring section on transactions but it mostly talks about handling exceptions. I was hoping to find some way of binding a hibernate session to a Spring transaction so that I can commit changes to hibernate objects when the transaction finishes. Is there a way to achieve this?

• How can I recursively read out directories in Perl?

  - by Przemek

  Hi, I want to read out a directory recursively to print the data-structure in an HTML-Page with Template::Toolkit. But I'm hanging in how to save the Paths and Files in a form that can be read our easy. My idea started like this sub list_dirs{ my ($rootPath) = @_; my (@paths); $rootPath .= '/' if($rootPath !~ /\/$/); for my $eachFile (glob($path.'*')) { if(-d $eachFile) { push (@paths, $eachFile); $paths[$i] = &list_dirs($eachFile); } else { push (@files, $eachFile); } } return @paths; } How could I solve this problem?

• wordpress filters documentation? Trying to understand add_filter()

  - by Chris J. Lee

  I read over the documentation several times and have been having a hard time trying to figure out what is going on with the function. I'm more and more confused after looking at the documentation, looking over the source code as well. add_filter($tag, $hook, $priority, $args); it seems to me the new function extends the parent function. What puzzle's me is what parts of the hook becomes overridden. in some examples in the documentation i see that some variables are replaced with the $args in your new $tag. I almost understood it all here: http://www.andrewnacin.com/2010/05/18/rethinking-template-tags-in-plugins/ but then i couldn't figure out how you pass arguments and which eventually get overriden. thanks in advance.

• "Mail merge"-like functionality in Dreamweaver, or in any other web editing tool?

  - by Chris Farmer

  I have inherited several related, low-traffic web sites to manage and edit. These sites are implemented with static html, and they've accrued lots of stray tags and other cruft. I want to try to clean these up and migrate them to some common page template framework to simplify design and data changes and improve overall consistency. The pages will change on the timescale of weeks, and since the current web hosting plan does not support any dynamic server technologies, I was hoping to just use Dreamweaver or some other tool to merge my content data with some templating structure. I'd like to do content updates every several days and then run the content back through my templates, resulting in new static html that I can upload to the host. Do any tools support this kind of poor-man's data-driven web application? Are there better ways to approach this problem, aside from moving to a new hosting plan and using ASP.NET or PHP?

• Consolidating files in a single directory before you link them into the final executable

  - by David

  I am working on Solaris 10, Sun Studio 11. I am refactoring some old code, and trying to write unit tests for them. My make file looks like: my_model.o:my_model.cc CC -c my_model.cc -I/../../include -library=stlport4 -instances=extern unit_test: unit_test.o my_model.o symbol_dictionary.o CC -o unit_test unit_test.o my_model.o symbol_dictionary.o -I../../include \ -library=stlport4 -instances=extern unit_test.o: unit_test.cc CC -c unit_test.cc -I/../../include -library=stlport4 -instances=extern symbol_dictionary.o: cd ../../test-fixtures && ($MAKE) symbol_dictionary.o mv ../../test-fixtures/symbol_dictionary.o . In the ../../test-fixtures makefile, I have the following target: symbol_dictionary.o: CC -c symbol_dictionary.cc -I/../../include -library=stlport4 -instances=extern I do the instances=extern because I had linking problems before, and this was the recommended solution. The consequence is in each directory that is being compiled, a SunWS_Cache directory is created to store the template instances. This is the long way to get to this question. Is it a standard practice to consolidate object files in a single directory before you link them?

• How to find image width and height dynamically and specify height, width attibutes if over certain d

  - by Wbdvlpr

  Hi, I display some data on my website and one of the data feed elements is an image. [title] => Product title [description] => some description [image] => www.some-domain.com/product-image/p12345.jpg I then display this image using <img alt="product" src="<?=$data['image']?>" /> Most of the images are 80x80, 120x100 or other less than 150 in width, which perfectly fit in the website template, but some of them are quite large such as 800x600 which distort the layout. I want a control on these types. I tried to set WIDTH="150", but as the width vary they dont look good. I was thinking If I could set a fixed width to images, say, larger than 250px then I can live with it for now. Any ideas how to achieve this? Thanks

• How does SWTBOT run a custom eclipse based application? I don't know how to specify my target application

  - by jlisam13

  I have an eclipse based application. I have heard of swtbot however I am having a hard time understanding how exactly does this tool run my application and how would I specify that. This eclipse based application has an executable and various configuration/plugin/features files. I have done the tutorials about swtbot and I have successfully completed them but they all just create a template application to test on. Is this even possible? If not do you guys have any alternatives for UI automation testing on eclipse based apps? Thanks.

• Apache server-side files caching via .htaccess?

  - by purpler

  Hi, I'm starting new website and gonna include several JS libs and would like to know how .htaccess file template should look like with caching of media and JS files on? Whats better for compression, GZip or Deflate? Is it better/faster solution to serve those JS libs of the Google CDN perhaps then locally? I'm asking CDN question since some of scripts served off GoogleCDN are potentially going to update and eventually break the website layout so i thought it would be better for me to host them locally and cache via webserver if its going to work with same/near-same speed.

• Changing the namespace for a Web Reference

  - by kdmurray

  When I add a web reference to a project, it comes up with a default namespace of: com.wpdevs.myservice. This is the namespace I'd have expected it to use in the application. When I add the using statement to the project, I have to add: using MyProject.com.wpdevs.myservice; I'd like to find a way to eliminate having to reference the project name in the using statement. The project I'm putting together now is destined to be converted into a VS Project template and having that rather strange reference in there, or even having a per-project reference, isn't something I'd like to have in the project.

• django url tag performance

  - by zxygentoo

  I was trying to integrate django-voting into my project following the RedditStyleVoting instruction. In my urls.py, i did something like this: url(r'^sections/(?P<object_id>\d+)/(?P<direction>up|down|clear)vote/?$', vote_on_object, dict( model=Section, template_object_name='section', template_name='script/section_confirm_vote.html', allow_xmlhttprequest=True ), name="section_vote", then, in my template: {% vote_by_user user on section as vote %} {% score_for_object section as score %} {% vote_by_user user on section as vote %} {% score_for_object section as score %} {{ score.score|default:0 }} It takes over 1.3s to load the page, but by hard coding it like this: {% vote_by_user user on section as vote %} {% score_for_object section as score %} {{ score.score|default:0 }} I got 50ms. Just avoid the url tag resolving stuff I got a 20+ times performance improvement. Is there something I did wrong? If not, then what's the best practice here, should we do things the right way or the fast way?

• Modular HTML in Adobe AIR? Is It Possible?

  - by Greg Bulmash

  When I write HTML with a PHP backend, I usually have a single header file and a single footer file with some PHP variables in them. The base skeleton for every page calls the header, contains the body content, and then calls the footer. That way, if I want to make changes to the header sitewide, I change one file. I'm working on developing the UI in my first Adobe AIR app and I'm wondering if there's some way to include such files in an HTML based page template there. Obviously, with the file read/write abilities in AIR, I can write a Javascript routine to pull data from a header file, parse it, and inject it into a placeholder. It just seems like such a kludge. I'm thinking there's gotta be some simple way to import a block of HTML into a page without an iFrame or complex post-processor. Something like a PHP include statement or perhaps the old Server Side Includes. Any methods you guys can recommend?

• Dynamic order by without using dynamic sql ?

• Is there a way to undo Mocha stubbing of any_instance?

  - by Steve Weet

  Within my controller specs I am stubbing out valid? for some routing tests, (based on Ryan Bates nifty_scaffold) as follows :- it "create action should render new template when model is invalid" do Company.any_instance.stubs(:valid?).returns(false) post :create response.should render_template(:new) end This is fine when I test the controllers in isolation. I also have the following in my model spec it "is valid with valid attributes" do @company.should be_valid end Again this works fine when tested in isolation. The problem comes if I run spec for both models and controllers. The model test always fails as the valid? method has been stubbed out. Is there a way for me to remove the stubbing of any_instance when the controller test is torn down. I have got around the problem by running the tests in reverse alphabetic sequence to ensure the model tests run before the controllers but I really don't like my tests being sequence dependant.

• file_get_contents() removing tab and new line characters

  - by Patrick Murray

  I am having an issue today with the file_get_contents() function. When reading large files, the newline and tab characters are often removed. Here is a minified example of how I am using this. I hope I am not the only one who has encountered this issue! :O Thank you for your time! <?php $file_name = "template.html"; $data = array( 'title' => 'Hello, World!', 'content'=> 'Hey stackoverflow!'); $file_contents = file_get_contents($file_name); foreach($data as $comment_name => $replacement_value){ $search = "<!-- ".strtoupper($comment_name)." -->"; $file_contents = str_replace($search, $replacement_value, $file_contents); } echo $file_contents; ?>

• Are pointers primitive types in C++?

  - by Space_C0wb0y

  I was wondering about the last constructor for std::string mentioned here. It says: template<class InputIterator> string (InputIterator begin, InputIterator end); If InputIterator is an integral type, behaves as the sixth constructor version (the one right above this) by typecasting begin and end to call it: string(static_cast<size_t>(begin),static_cast<char>(end)); In any other case, the parameters are taken as iterators, and the content is initialized with the values of the elements that go from the element referred by iterator begin to the element right before the one referred by iterator end. So what does that mean if InputIterator is a char * ?

• Why is url not registered?(Drupal 6.x)

  - by Andrew

  I'm using hook_menu to register new url so that accessing this url would return some data to ajax function. As title suggested, this url is not registered. How do I know that? I've tried typing this in address bar but, drupal, return main template only rather than the tests string that I created. I'm positive that my module is working for php issues error if I intentionally write wrong syntax. And, yes, I clear cache whenever I make changes. Here's the code - function test_menu() { $my_form['test'] = array( 'title' => 'Test address', 'page callback' => 'test', 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); return $my_form; } function test(){ $a= "testing"; return $a; }

• Getting the hang of CodeIgniter - Templating / loading views

  - by kilrizzy

  Attempting to learn CI and going through the docs to get a better understanding. Without getting a separate library, I could make a template by including a list of views like so: $this->load->view('header'); $this->load->view('navigation'); $this->load->view('sidenav_open'); $this->load->view('blocks/userinfo'); $this->load->view('blocks/stats'); $this->load->view('sidenav_close'); $this->load->view('content',$data); $this->load->view('footer'); This makes sense but would I actually have that on each of my controllers (pages)? Not sure if there is a way to include this in the initial controller (welcome) and then in the others somehow reference it? Or perhaps there is something I am missing completely
