• Can't find a Wordpress image/photo gallery plugin

  - by mgroves

  I've been looking at Wordpress plugins for photo galleries (so maybe this is for superuser.com), and I've been very frustrated so far. It seems like what I'd like to do would be a very common use case: Admin: Be able to upload multiple pictures (at a time) Admin: Be able to assign a "gallery" to those pictures as I upload them User: Be able to go to a page with a (paged) list of all galleries User: Be able to click on gallery and view the images (again, probably paged) in that gallery User: Be able to click on an image to get larger/largest sizes User: Be able to leave comments on individual pictures (this is a "nice to have") The images/galleries could be totally independent of posts/pages, but it would be nice to be able to embed those images/galleries into posts/pages when necessary. Is there anything out there like this that I'm missing? I've tried a handful of plugins and none of them seem to be for a use case anywhere close to what I'm looking for. One of the reasons I'm trying to use Wordpress is to reduce time spent coding everything I want.

• schema for storing different varchar fields over time?

  - by Henry

  This app I'm working on needs to store some meta data fields about an entity. The problem is that we can already foresee that these fields are going to change a lot in the future. I'm using Hibernate (in ColdFusion) and each entity's properties are translated to one column in the entity table, but altering table columns later down the raod will be costly and error-prone right? Should I go for something like this? MetaDataField ----- metaDataFieldID (PK), name FieldValue ---------- EntityID (PK, FK), metaDataFieldID (PK, FK), value [varchar(255)] Is this common? Anything to watch out for? p.s. I also thought of using XML on SQL Server 05+. After talking to some ppl, seems like it is not a viable solution 'cause it will be too slow for doing certain query for reporting purposes.

• Forbid developer to commit code because of making weekly build

  - by Xinwang

  Our development team (about 40 developers) has a formal build every two weeks. We have a process that in the "build day", every developers are forbiden to commit code into SVN. I don't think this is a good idea because: Build will take days (even weeks in bad time) to make and BVT. People couldn't comit code as they will, they will not work. People will comit all codes in a hurge pack, so the common is hard to write. I want know if your team has same policy, and if not how do you take this situation. Thanks

• Passing arguments to java vm from NSIS script

  - by CodeBuddy

  I'm developing my first java application using Eclipse. I've recently needed to adjust the amount of memory allocated by passing -Xmx256M to the JVM. The application is currently package up as a runnable jar and installed using the NSIS. I'm having a problem passing arguments to the jar file once its installed. What is the common practice for doing this? Here is what I'm currently doing in my nsi file: CreateShortcut "$SMPROGRAMS\$StartMenuGroup\$(^Name).lnk" "$SYSDIR\javaw.exe" "-jar -Xmx256M $INSTDIR\Foo.jar" This results in the following being created as the shortcut Target on windows: C:\WINDOWS\system32\javaw.exe -jar -Xmx256M C:\Program Files\Foo\Foo.jar Unfortunately this does not work due to the space in C:\Program Files, If I change the link created manually to include quotes all is well: C:\WINDOWS\system32\javaw.exe -jar -Xmx256M "C:\Program Files\Foo\Foo.jar"

• disable text drag and drop

  - by maniek

  There is a common feature of modern browsers where a user can select some text and drag it to an input field. Within the same field it causes moving of text, between different fields it does copying. How do I disable that? If there is no portable way, I am mostly interested in firefox. This is an intranet webapp, so I am also interested in modifying the browser/getting a plugin to do this. Maybe some system-level settings (I`m on windows XP)? I need to keep the default select-copy-paste functionality. The background is I have multiple-field data entry forms, and users often drag something by mistake.

• How to make sure web services are kept stable from one release to the next?

  - by Tor Hovland

  The company where I work is a software vendor with a suite of applications. There are also a number of web services, and of course they have to be kept stable even if the applications change. We haven't always succeeded with this, and sometimes a customer finds that a service is not behaving as before after upgrading. We now want to handle this better. In general, web services shouldn't change, and if they have to, at least we will know about it and document the change. But how do we ensure this? One idea is to compare the WSDL files with the previous versions at every release. That will make sure the interfaces don't change, but it won't detect that the behavior changes, for example if a bug is introduced in some common library. Another idea is to build up a suite of service tests, for example using soapUI. But then we'll never know if we have covered enough cases. What are some best practices regarding this?

• Using free function as pseudo-constructors to exploit template parameter deduction

  - by Poita_

  Is it a common pattern/idiom to use free functions as pseudo-constructors to avoid having to explicitly specify template parameters? For example, everyone knows about std::make_pair, which uses its parameters to deduce the pair types: template <class A, class B> std::pair<A, B> make_pair(A a, B b) { return std::pair<A, B>(a, b); } // This allows you to call make_pair(1, 2), // instead of having to type pair<int, int>(1, 2) // as you can't get type deduction from the constructor. I find myself using this quite often, so I was just wondering if many other people use it, and if there is a name for this pattern?

• How do I branch an individual file in SVN?

  - by Michael Carman

  The subversion concept of branching appears to be focused on creating an [un]stable fork of the entire repository on which to do development. Is there a mechanism for creating branches of individual files? For a use case, think of a common header (*.h) file that has multiple platform-specific source (*.c) implementations. This type of branch is a permanent one. All of these branches would see ongoing development with occasional cross-branch merging. This is in sharp contrast to unstable development/stable release branches which generally have a finite lifespan. I do not want to branch the entire repository (cheap or not) as it would create an unreasonable amount of maintenance to continuously merge between the trunk and all the branches. At present I'm using ClearCase, which has a different concept of branching that makes this easy. I've been asked to consider transitioning to SVN but this paradigm difference is important. I'm much more concerned about being able to easily create alternate versions for individual files than about things like cutting a stable release branch.

• Using 'git pull' vs 'git checkout -f' for website deployment

  - by Michelle

  I've found two common approaches to automatically deploying website updates using a bare remote repo. The first requires that the repo is cloned into the document root of the webserver and in the post-update hook a git pull is used. cd /srv/www/siteA/ || exit unset GIT_DIR git pull hub master The second approach adds a 'detached work tree' to the bare repository. The post-receive hook uses git checkout -f to replicate the repository's HEAD into the work directory which is the webservers document root i.e. GIT_WORK_TREE=/srv/www/siteA/ git checkout -f The first approach has the advantage that changes made in the websites working directory can be committed and pushed back to the bare repo (however files should not be updated on the live server). The second approach has the advantage that the git directory is not within the document root but this is easily solved using htaccess. Is one method objectively better than the other in terms of best practice? What other advantages and disadvantages am I missing?

• The Definitive Guide To Website Authentication (beta)

  - by Michiel de Mare

  Form Based Authentication For Websites Please help us create the definitive resource for this topic. We believe that stackoverflow should not just be a resource for very specific technical questions, but also for general guidelines on how to solve variations on common problems. "Form Based Authentication For Websites" should be a fine topic for such an experiment. It should include topics such as: how to log in how to remain logged in how to store passwords using secret questions forgotten password functionality OpenID "Remember me" checkbox Browser autocompletion of usernames and passwords secret urls (public urls protected by digest) checking password strength email validation and much more It should not include things like: roles and authorization http basic authentication Please help us by Suggesting subtopics Submitting good articles about this subject Editing the official answer (as soon as you have enough karma) UPDATE: See the terrific 7-part series by Jens Roland below.

• Is there a decent JSON editor around?

  - by al4nis

  I'm looking for a JSON editor that is able to do syntax checking and outline view. Browser-based editors are not an option as they are clumsy for editing lots of local files. Eclipse plug-in would be ideal, but I would be happy with anything that works. I found only two so far, those in Aptana Studio Pro and Spket IDE (both available as plug-ins for Eclipse). While they have decent outline views, their syntax checking doesn't catch most of the common errors (like missing commas or braces) which makes them almost useless.

• PHP: session isnt saving before header redirect

  - by Matt

  Hi guys, I have read through the php manual for this problem and it seems quite a common issue but i have yet to find a solution. I am saving sessions in a database. My code is as follows: // session $_SESSION['userID'] = $user->id; header('Location: /subdirectory/index.php'); Then at the top of index.php after the session_start(), i have var_dumped the $_SESSION global and the userID is not in there. As i said ive looked through the PHP manual (http://php.net/manual/en/function.session-write-close.php) and neither session_write_close or session_regenerate_id(true) worked for me. Does anybody know a solution? Edit: I have session_start() at the top of my file. When i var_dump the session global before the header redirect, i see the userID in there, but not in the other file, which is in a subdirectory of this script Thanks, Matt

• getResourceAsStream not loading resource in webapp

  - by mangst

  I have a web application that uses a library which resides in TOMCAT_HOME/common/lib. This library looks for a properties file at the root of the classpath (in a class called ApplicationConfig): ApplicationConfig.class.getResourceAsStream("/hv-application.properties"); My Tomcat web application contains this properties file. It is in WEB-INF/classes, which is the root of the classpath right? However, at runtime, when it tries to load the properties file, it throws an exception because it can't find it (getResourceAsStream returns null). Everything works fine if my application is a simple, standalone Java application. Does Tomcat cause the getResourceAsStream method to act differently? I know there's a lot of similar questions out there, but none of them have helped unfortunately. Thanks.

• How do i get out of the habit of procedural programming and into object oriented programming?

  - by Shadi Almosri

  Hiya all, I'm hoping to get some tips to kinda help me break out of what i consider after all these years a bad habit of procedural programming. Every time i attempt to do a project in OOP i end up eventually reverting to procedural. I guess i'm not completely convinced with OOP (even though i think i've heard everything good about it!). So i guess any good practical examples of common programming tasks that i often carry out such as user authentication/management, data parsing, CMS/Blogging/eComs are the kinda of things i do often, yet i haven't been able to get my head around how to do them in OOP and away from procedural, especially as the systems i build tend to work and work well. One thing i can see as a downfall to my development, is that i do reuse my code often, and it often needs more rewrites and improvement, but i sometimes consider this as a natural evolution of my software development. Yet i want to change! to my fellow programmers, help :) any tips on how i can break out of this nasty habbit?

• How to organize code using an optional assembly reference?

  - by apoorv020

  I am working on a project and want to optionally use an assembly if available. This assembly is only available on WS 2008 R2, and my ideal product whould be a common binary for both computers with and without the assembly. However, I'm primarily developing on a Windows 7 machine, where I cannot install the assembly. How can I organize my code so that I can (with minimum changes) build my code on a machine without the assembly and secondly, how do I ensure that I call the assembly functions only when it is present. (NOTE : The only use of the optional assembly is to instantiate a class in the library and repeatedly call a (single) function of the class, which returns a boolean. The assembly is fsrmlib, which exposes advanced file system management operations on WS08R2.) I'm currently thinking of writing a wrapper class, which will always return true if the assembly is not present. Is this the right way to go about doing this?

• Method hiding with interfaces

  - by fearofawhackplanet

  interface IFoo { int MyReadOnlyVar { get; } } class Foo : IFoo { int MyReadOnlyVar { get; set; } } public IFoo GetFoo() { return new Foo { MyReadOnlyVar = 1 }; } Is the above an acceptable way of implementing a readonly/immutable object? The immutability of IFoo can be broken with a temporary cast to Foo. In general (non-critical) cases, is hiding functionality through interfaces a common pattern? Or is it considered lazy coding? Or even an anti-pattern?

• open source project requirements

  - by skidding

  I know it's a very common question, but I don't see a previous one to be asked, since I'm interested in the basic steps, nothing in particular. It's the first time I want to license one of my projects, and it turns out, I don't know much about it. Let's say I want to use the MIT License. Do I just take the definition and paste it into my files? Does it need to be in ALL the files, or just one? or? I don't want any fancy rights so MIT has been recommended to me, do you suggest something else? I'm looking for impartial opinions. Thanks. What other aspects must I take into account? It's PHP, btw.

• How to achieve table like rows within container using CSS

  - by Barry

  I'm helping an artist maintain her website and have inherited some pretty outdated code. Have moved lots of redundant common code to include files and am now working on moving from inline styles to more CSS-driven styles. For the gallery pages, e.g. http://artistsatlaketahoe.com/abstract.html, a lot of inline styling is used to force the current layout. My preference would be to replace this entirely with CSS that presents the following table-like layout within the "content" div: [image] [image descriptives and purchase button] [image] [image descriptives and purchase button] [image] [image descriptives and purchase button] I'd like to middle-align the image descriptives & purchase button relative to the image if possible. And then apply some padding above and below each row to stop using tags for vertical spacing. Any ideas how to create a div that I can use to get this kind of layout? Thanks!

• How to make .NET WebForm Routing work with Authorization

  - by jakmas

  I have routes that are being registered from the database into an asp.net website (non MVC). The routes register fine, they all work when I am logged in. What I am trying to do is create a landing page based on some route data: Page is [site]/landing/dell The route looks like: "landing/{client}" and it routes to my page Login.aspx, in there I get the client out of the route, then display some custom brand data based on the value. In my web.config, I have my authentication mode set to forms, with my loginUrl = "Login.aspx" When the user does not have the authorization cookie, it redirects the user to: [site]/Login.aspx?ReturnUrl=%2flanding%2fdell instead of keeping the route url, and displaying the correct data. The IIS server actually does not even process the route at all, just sends the user to the Login.aspx page. I have tried several additions to my web.config: etc, and many variations, but nothing seems to work. Ideas anyone? I assume this is a common issue, and it is just not well documented.

• Conseqences of assigning self

  - by Vegar

  Hi, Found a piece of code today, that I find a little smelly... TMyObject.LoadFromFile(const filename: String); begin if fileExists(filename) then self := TSomeObjectStreamer.ReadObjectFromFile(filename); end; If this code works, it will atleast leak some memory, but does it work? Is OK to assign to self in this manner? What if the streamed object is of a different subclass then the original self? What if the streamed object is of a different class with no common ancestore to the original self?

• Scale image to completely fill bounding box

  - by Larsenal

  For instance, if I need to fill a bounding box that is 100px wide by 50px tall, the following input images would have the following behavior: 200w x 200h gets scaled down 50% and 25% gets chopped off the top and bottom. 200w x 100h gets scaled down 50% with no cropping. 100w x 200h gets is not scaled, but 75px get chopped off top and bottom. This seems like it'd be a common resizing function, but I haven't been able to track down an example of the algorithm. Will accept answer in any language including pseudo code. A link to a page with the answer is great too!

• Groovy GDK equivalent of Apache Commons StringUtils.capitalize(str) or Perl's ucfirst(str)

  - by knorv

  Yes/no-question: Is there a Groovy GDK function to capitalize the first character of a string? I'm looking for a Groovy equivalent of Perl's ucfirst(..) or Apache Commons StringUtils.capitalize(str) (the latter capitalizes the first letter of all words in the input string). I'm currently coding this by hand using .. str = str[0].toUpperCase() + str[1 .. str.size() - 1] .. which works, but I assume there is a more Groovy way to do it. I'd imagine ucfirst(..) being a more common operation than say center(..) which is a standard method in the Groovy GDK (see http://groovy.codehaus.org/groovy-jdk/java/lang/String.html).

• PHP Dynamic Breadcrumb

  Hello, I got this code from someone and it works very well, I just want to remove the link from the last element of the array: //get rid of empty parts $crumbs = array_filter($crumbs); $result = array(); $path = ''; foreach($crumbs as $crumb){ $path .= '/' . $crumb; $name = ucfirst(str_replace(array(".php","_"),array(""," "), $crumb)); $result[] = "<a href=\"$path\">$name</a>"; } print implode(' > ', $result); This will output for example: Content Common File I just want a to remove the link from the last item - "File" to be just plain text.. I tried myself to count the array items and then if the array item is the last one then to print as plain text the last item.. but I'm still noob, I haven't managed to get a proper result.. Thank you!

• Cannot get mysql gem to work in Snow Leopard, unable to setup ruby on rails environment

• Are there any other Java schedulers besides Quartz(FOSS) and Flux(Commercial)

  - by mP

  I am interested in finding out about other job scheduling packages besides Quartz and Flux. Given the plethora of web frameworks i find it perculiar that there is really only one scheduler. Are there others that perhaps are very much unknown/unpopular ? Spring Batch Not really a scheduling solution but rather a batch job coordinator etc. http://static.springsource.org/spring-batch/faq.html#schedulers How does Spring Batch differ from Quartz? Is there a place for them both in a solution? Spring Batch and Quartz have different goals. Spring Batch provides functionality for processing large volumes of data and Quartz provides functionality for scheduling tasks. So Quartz could complement Spring Batch, but are not excluding technologies. A common combination would be to use Quartz as a trigger for a Spring Batch job using a Cron expression and the Spring Core convenience SchedulerFactoryBean .
