  • Does Wicket hamper SEO or search engines ability to crawl?

    - by Nick
    We're coming from GWT projects and because of problems with SEO not liking GWT for our next project we're going to move clear of GWT (mainly because seo is a high priority for this next project). In choosing a new framework, I'm looking at Wicket and liking what I've seen so far. I've only done a few tutorials, but in looking at the war layout (from these tutorials) it looks like most of the html pages are in the WEB-INF folder. It this going to cause problems for SEO and search engines crawling through the sites files? Ideally, I'd like to use Wicket with some AJAX and deploy to Google App Engine.

  • using libcurl to create a standalone site-polling program

    - by aitchnyu
    I am creating a standalone (no DLLs) windows C/C++ program that uses HTTP POST to periodically send data to an HTTP server. I identified libCURL as the HTTP client library as it seems simple and reliable. I still need to identify the environment (an IDE) which I can use to develop my project. My program has: poller- which checks the status of the connection a file writer when polled link is down a component which POSTs the file when link is up What is the appropriate IDE for this project? I heard endorsements for DevC++ and Visual C. I am a newb to coding and this site. Pardon me if I am unclear in anything.

  • [Zend Framework] Is there any way to use more than 1 bootstrap class?

    - by rasouza
    It should sound workaround or something like, but I'll tell you what: I chose to have a separated "project" with every library I could use. It's like a global library which I included Zend library, Doctrine ORM, JQuery, Blueprint CSS, etc. Then I set the include path. Nothing wrong. The problem is: I'd like to have also a global bootstrap class inside the library folder and an individual bootstrap class on each project I create for individual use. I don't know how to set more than 1 bootstrap class. Is it possible?

  • How to code for Alternate Course AKA Rainy Day Scenary?

    - by janetsmith
    Alternate course is something when user doesn't do what you expected, e.g. key in wrong password, pressing back button, or database error. For any programming project, alternate course accounts for more than 50% of a project timeline. It is important. However, most computer books only focus on Basic Course (when everything goes fine). Basic course is rather simple, compared to Alternate course, because this is normally given by client. Alternate course is what we, as a programmer or Business Analyst needs to take care of. Java has some built-in mechanism (try-catch) to force us to handle those unexpected behavior. The question is, how to handle them? Any pattern to follow? Any guideline or industry practice for handling alternate course?

  • Can't find AVD or SDK manager in Eclipse

    - by zigzag
    Seems like I'm having some problems after updating my android sdk tools and platform-tools using the sdk manager. The problem is that, after updating, I found that the avd or sdk options in the windows dropdown menu in eclipse are gone! And, I can't find any option to create an android project from file-new projects any more. I tried removing the ADT from eclipse and the software site "https://dl-ssl.google.com/android/eclipse/" from "available software sites" and then reinstalled the ADT from "https://dl-ssl.google.com/android/eclipse/" using help-install new software. The installation was successful, but I still don't have any option for shortcuts to the SDK manager or the AVD in eclipse, and neither can I create a new android project. By the way, the android perspectives are not gone, they are still here. Also, I can manually open the avd and sdk manager from the directory where I have installed them. Can anyone please show me a workaround? Any help would be greatly appreciated.

  • segmented reduction with scattered segments

    - by Christian Rau
    I got to solve a pretty standard problem on the GPU, but I'm quite new to practical GPGPU, so I'm looking for ideas to approach this problem. I have many points in 3-space which are assigned to a very small number of groups (each point belongs to one group), specifically 15 in this case (doesn't ever change). Now I want to compute the mean and covariance matrix of all the groups. So on the CPU it's roughly the same as: for each point p { mean[p.group] += p.pos; covariance[p.group] += p.pos * p.pos; ++count[p.group]; } for each group g { mean[g] /= count[g]; covariance[g] = covariance[g]/count[g] - mean[g]*mean[g]; } Since the number of groups is extremely small, the last step can be done on the CPU (I need those values on the CPU, anyway). The first step is actually just a segmented reduction, but with the segments scattered around. So the first idea I came up with, was to first sort the points by their groups. I thought about a simple bucket sort using atomic_inc to compute bucket sizes and per-point relocation indices (got a better idea for sorting?, atomics may not be the best idea). After that they're sorted by groups and I could possibly come up with an adaption of the segmented scan algorithms presented here. But in this special case, I got a very large amount of data per point (9-10 floats, maybe even doubles if the need arises), so the standard algorithms using a shared memory element per thread and a thread per point might make problems regarding per-multiprocessor resources as shared memory or registers (Ok, much more on compute capability 1.x than 2.x, but still). Due to the very small and constant number of groups I thought there might be better approaches. Maybe there are already existing ideas suited for these specific properties of such a standard problem. Or maybe my general approach isn't that bad and you got ideas for improving the individual steps, like a good sorting algorithm suited for a very small number of keys or some segmented reduction algorithm minimizing shared memory/register usage. I'm looking for general approaches and don't want to use external libraries. FWIW I'm using OpenCL, but it shouldn't really matter as the general concepts of GPU computing don't really differ over the major frameworks.

  • LINQ-to-SQL vs stored procedures?

    - by scottmarlowe
    I took a look at the "Beginner's Guide to LINQ" post here on StackOverflow (http://stackoverflow.com/questions/8050/beginners-guide-to-linq), but had a follow-up question: We're about to ramp up a new project where nearly all of our database op's will be fairly simple data retrievals (there's another segment of the project which already writes the data). Most of our other projects up to this point make use of stored procedures for such things. However, I'd like to leverage LINQ-to-SQL if it makes more sense. So, the question is this: For simple data retrievals, which approach is better, LINQ-to-SQL or stored procs? Any specific pro's or con's? Thanks.

  • Svn merging trunk and branches

    - by Darko Petreski
    Hi All, I have a huge project. I need to make a branch - this will be version 2 of the project, but I also need to keep the trunk and change it in parallel with the branch 1 as bug fix to the version 1. I need to merge bug fixes from the trunk to the branch 1 while adding new features to the branch. At the end I need to merge all changes back in the trunk and make new tag from it. So I need bug fix for version 1, new branch for version 2 and of course merging bug fixes in the version 2. I am using svn but the svn makes problems all the time. I cannot merge anything without conflicts. Can someone give me an advice what to do? Regards

  • How can should I set up Flex 3 projects that reference common controls?

    - by Amy
    I'm not a flash developer, I'm having issues figuring out how I should set up these two projects that I have in Flex Builder. I've already created projA which has a .mxml that references several custom controls & skins from com.xxx.controls within projA I now have to build projB which also has a .mxml that will create a different .swf. I want to use some of the same controls from projA I currently build projA through the command line and nant and will need to do the same for projB. Should I create a new project to move all of the common controls into? How do I then use this library project in both the projects & compile via command? Thanks!

  • Other SecurityManager implementations available?

    - by mhaller
    Is there any other implementation (e.g. in an OSS project) of a Java SecurityManager available which has more features than the one in the JDK? I'm looking for features like configurable at runtime policies updateable at runtime, read from other data sources than a security.policy file Thread-aware, e.g. different policies per Thread Higher-level policies, e.g. "Disable network functions, but allow JDBC traffic" Common predefined policies, e.g. "Allow read-access to usual system properties like file.encoding or line.separator, but disallow read-access to user.home" Monitoring and audit trace logging, e.g. "Log all file access, log all network access going NOT to knownhost.example.org" Blocking jobs "requesting" a permission until an administrator grants permission, letting the thread/job continue ... I'm pretty sure that application servers (at least the commercial ones) have their own SecurityManager implementation or at least their own policy configuration. I'm wondering if there is any free project with similar requirements.

  • Subversion: What to do with branches, tags and trunk folders?

    - by bartclaeys
    A little background first: I'm a designer/developer and decided to use subversion for a personal project. I'm the only one working on this project. I've setup a Beanstalk account and installed Versions on Mac. Locally I have MySQL and PHP running through MAMP. First thing I did in Versions is click the 'checkout' button. I selected my webroot folder and a folder has been created with three subfolders: branches, tags, trunk. I don't understand what to do with this. My code lives in the webroot and a bunch of subfolders and I can't move my code to any of the three folders without breaking things. So, my question is, how do I tell Versions that my code is in the webroot folder and not in the folder it created itself?

  • "_FILE_AND_LINE_ is not defined in this scope" (compiling RakNet NAT examples in OS X)

    - by Michael F
    Hello! I'm working on a RakNet-based project (using 3.8 on OS X 10.6), and I'm trying to work through the various examples that demonstrate the parts of RakNet I want to use. For the "NatCompleteClient" example, I've imported the source into a command-line project in XCode, along with the UPNP dependency. At compile time I've had a few errors in the UPNP section, though, and I can't find any guidance on this. In UPNPPortForwarder.mm, there are 7 lines that use _FILE_AND_LINE_, and the compiler is not happy; for example on line 232: foundInterfaces.Deallocate(r1,_FILE_AND_LINE_); causes: UPNPPortForwarder.mm:232: error: '_FILE_AND_LINE_' was not declared in this scope Can anyone tell me what this is all about? That variable doesn't seem to get talked about very often... or Google doesn't like to find it.

  • Java Session Like Object

    - by scriptmonster
    I have been developing a project and in this project i have designed my code to do the same job after a specified time interval continuously. The job that wanted to be done has a lot of distinct cycles. The interval is small to execute them normally thus i used threads. Until that point everything is clear for me. To decrease the process and information transaction i wanted to put an session like object that holds the given data and provide it to any thread at anytime. With this object i plan to not query the same configuration information from database at everytime but if it exists on the session take it else query and store on session. I'm not sure how to implement this structure. Regards,

  • What to Learn: Rails 1.2.4 -> Rails 3

    - by Saterus
    I've recently convinced my management that our outdated version of Rails is slowing us down enough to warrant an upgrade. The approach we're taking is to start a fresh project with current technology rather than a painful upgrade. Our requirements for the project have changed and this will be much easier. The biggest problem is actually that my knowledge of Rails is out of date. I've dealt only with Rails 1.2.4 while the rest of the world has moved on long ago. What topics have I missed by being buried in my work instead of keeping up with the current Rails fashion? I'm hesitant to dig through blogs at random because I'm not sure how much has changed between the intervening versions of Rails. It's no use to learn Rails 2.1-2.3 specific stuff that is no longer useful for Rails 3.

  • Maven profile properties are not "overriding"

    - by Nazar
    I have Maven multi-module project with such structure: parent-pom-project -- module1 -- module2 At the parent-pom-project I have such pom.xml <modules> <module>module1</module> </modules> ... <profiles> <profile> <id>local</id> <properties> <prop>local_prop</prop> </properties> </profile> <profile> <id>test</id> <modules> <module>module2</module> </modules> <properties> <prop>test_prop</prop> </properties> </profile> </profiles> At all pom.xml files I have such tag: <build> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> </resource> <resource> <directory>src/test/resources</directory> <filtering>true</filtering> </resource> </resources> </build> At module1 and module2 in resource directory I have properties files with such text: prop=${prop} The problem is that after mvn clean install or mvn clean install -Ptest or even mvn clean install -P test I get prop=local_prop If I user test profile for build module2 is also builded, but properties are used from local profile. I use Maven 3.0.3. Anybody have any ideas?
