  • Constructive criticism for my bounce rate being so high [closed]

    - by Daniel
    The bounce rate on my website's product pages is 80%, which is terrible. Could you offer any opinions on whether you consider the user experience to be bad, and how I could possibly improve it? Other pages, such as the home and category pages, have acceptable bounce rates, but the vast majority of my traffic lands on the product pages. I already tried removing some Google ads for a couple of days, but this didn't seem to help at all. I'm working on doing A/B testing at the moment. (It's tricky, as the site is based on a CMS - I custom coded the [Joomla] component, so hopefully I can get this testing working.)

  • CAMeditor v1.9 &ndash; thoughts and reflections

    - by david.webber(at)oracle.com
    We recently published the latest iteration of the CAMeditor tool on Sourceforge.net including more enhancements to the NIEM capabilities. This release represented an incremental improvement over the prior version with mostly bug fixes and patches. We’re now working on the full v2.0 release which will feature substantial improvements and new features in practically all areas.  Most importantly we are improving the dictionary handling and providing the ability to visually design new exchange schema directly from dictionary sets of components. In addition we are doing some interim release work on 1.9.x with patches and enhancements particularly to support running on Ubuntu and non-Windows platforms. And we are also providing an Ant script based deployment for the CAMV validation engine so you can do unit testing of batches of templates and XML instance samples using command line scripts. More updates will be forthcoming as we make early release versions available for testing purposes.

  • When does a game idea cross the line between homage/parody to ripoff?

    - by Daniel T.
    I'm not sure where this question belongs, but as it pertains to the development of a game idea, I figured I'd try to post it here. Recently I've been inspired to create a game based on another game I've played. However, the idea that I have is very similar to the original game. I was wondering, when does a game idea cross from being a homage or parody into the realm of being a ripoff? Are there any hard or fast rules or does this cross into a gray area?

  • Is there an equivalent to the Max OS X software Hazel that runs on Ubuntu?

    - by Stuart Woodward
    Is there an equivalent to the Max OS X software Hazel that runs on Ubuntu? "Hazel watches whatever folders you tell it to, automatically organizing your files according to the rules you create. It features a rule interface [..]. Have Hazel move files around based on name, date, type, what site/email address it came from [..] and much more. Automatically put your music in your Music folder, movies in Movies. Keep your downloads off the desktop and put them where they are supposed to be." This question probably won't make sense unless you have used Hazel, but basically you can define rules via the GUI to move and rename files automatically to make an automated workflow.

  • Java Developers: Open-source Modules, Great Tools, Opportunity.

    - by Paul Sorensen
    The role of Java developer may just be better than ever. An excellent article in Java Magazine discusses the availability of web-based tools that help development teams more effectively manage their projects and modules. If you are a Java developer you should definitely read this article. I especially like the Expert Opinions scattered throughout the article. These highlight real-world usage of the latest and greatest development tools.  As you consider steps to move your career forward, consider Java certification. Oracle has over 15 unique Java certification credentials available. The process of becoming certified in Java and preparing for your exams will require you to study, learn and practice (code). All of this activity will help you sharpen your skills and increase your working knowledge of Java - making you a better developer and more valuable member of your team. You can use the Certification Finder on the Oracle certification homepage to find a Java certification that is right for you. Thanks!

  • How to modify VBO data

    - by Romeo
    I am learning LWJGL so i can start working on my game. In order to learn LWJGL I got the idea to implement the map builder so I can get comfortable with graphics programming. Now, for the map creation tool I need to draw new elements or draw the old one's with different coordinates. Let me explain this: My game will be a 2D scroller. The map will be consisting of multiple rectangles ( 2 strip triangles). When I click my left-mouse button i want to start the rectangle and when I release it I want to stop the rectangle bottom-right at that position. As I want to use VBOs I want to know how to modify data inside the VBO based on user input. Should i have a copy of a vertex array and then add the whole array to the VBO at each user input? How is usually implemented the VBO update?

  • Where to draw the line between front end and back end

    - by Twincascos
    I was recently contracted to develop a smarty theme for an automated SOHO phone answering service. The team who had built the backend wouldn't allow me access to any of the back end nor tell me anything about it, their smarty set up, smarty plugins, data base interface api, server set-up, nothing. Nor could I have access to the server nor a beta domain, basically zero co-operation. So I set up a local server with Smarty and built the template based on what I guessed would be their best practice, commented my code like crazy, wrote all the needed javascript, css, and template files. Then I sent them packaged to the backend team and hoped for the best. With half of a project team failing to cooperate or even communicate I am now concerned that they may reply saying that everything is wrong and they may refuse to implement the new front end. I'm curious to know if others encounter this type of situation and what you may have done to protect yourselves.

  • Squid3 not caching simple request and response

    - by Nick Spacek
    Hi folks, I've pared down my squid.conf to try to figure this out: http_port 80 accel defaultsite=host.to.cache cache_peer ip.to.cache parent 80 0 no-query originserver acl our_sites dstdomain host.to.cache http_access allow our_sites refresh_pattern . 1 20% 4320 Requests are being proxied correctly, so that's a start. Here's a request: GET http://host.to.cache/path?some_param=true Accept: */* Accept-Charset: ISO-8859-1,utf-8 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en Connection: keep-alive Host: host.to.cache User-Agent: myuseragent And the response: Connection: keep-alive Content-Length: 585 Content-Type: application/xml Date: Thu, 06 Jan 2011 18:33:11 GMT Via: 1.0 localhost (squid/3.0.STABLE19) X-Cache: MISS from localhost X-Cache-Lookup: MISS from localhost:80 The response has no caching-related headers, but I thought that refresh_pattern would set a default behavior for responses without caching-related headers. For my test, I wanted to cache everything for one minute at minimum. Am I missing something obvious? I did take a peek at this question: Squid isn't caching ...and ran through the page here: http://www.mnot.net/cache_docs/ briefly, but didn't see anything relevant (not to say that there isn't, I could have missed something). Thanks for any help.

  • Interacting with scene from controller/app delegate cocos2d

    - by cjroebuck
    I'm attempting to make my first cocos2d (for iphone) multiplayer game and having difficulty understanding how to interact with a scene once it is running. The game is a simple turn-based one and so I have a GameController class which co-ordinates the rounds. I also have a GameScene class which is the actual scene that is displayed during a round of the game. The basic interaction I need is for the GameController to be able to pass messages to the GameScene class.. such as StartRound/StopRound etc. The thing that complicates this is that I am loading the GameScene with a LoadingScene class which simply initialises the scene and replaces the current scene with this one, so there is no reference from GameController to GameScene, so passing messages is quite tricky. Does anyone have any ways to get around this, ideally I would still like to use a Loading class as it smooths out the memory hit when replacing scenes.

  • A Visual Studio Release Grows in Brooklyn

    - by andrewbrust
    Yesterday, Microsoft held its flagship launch event for Office 2010 in Manhattan.  Today, the Redmond software company is holding a local launch event for Visual Studio (VS) 2010, in Brooklyn.  How come information workers get the 212 treatment and developers are relegated to 718? Well, here’s the thing: the Brooklyn Marriott is actually a great place for an event, but you need some intimate knowledge of New York City to know that.  NBC’s Studio 8H, where the Office launch was held yesterday (and from where SNL is broadcast) is a pretty small venue, but you’d need some inside knowledge to recognize that.  Likewise, while Office 2010 is a product whose value is apparent.  Appreciating VS 2010’s value takes a bit more savvy.  Setting aside its year-based designation, this release of VS, counting the old Visual Basic releases, is the 10th version of the product.  How can a developer audience get excited about an integrated development environment when it reaches double-digit version numbers?  Well, it can be tough.  Luckily, Microsoft sent Jay Schmelzer, a Group Program Manager from the Visual Studio team in Redmond, to come tell the Brooklyn audience why they should be excited. Turns out there’s a lot of reasons.  Support fro SharePoint development is a big one.  In previous versions of VS, that support has been anemic, at best.  Shortage of SharePoint developers is a huge issue in the industry, and this should help.  There’s also built in support for Windows Azure (Microsoft’s cloud platform) and, through a download, support for the forthcoming Windows Phone 7 platform.  ASP.NET MVC, a “close-to-the-metal” Web development option that does away with the Web Forms abstraction layer, has a first-class presence in VS.  So too does jQuery, the Open Source environment that makes JavaScript development a breeze.  The jQuery support is so good that Microsoft now contributes to that Open Source project and offers IntelliSense support for it in the code editor. Speaking of the VS code editor, it now supports multi-monitor setups, zoom-in, and block selection.  If you’re not a developer, this may sound confusing and minute.  I’ll just say that for people who are developers these are little things that really contribute to productivity, and that translates into lower development costs. The really cool demo, though, was around Visual Studio 2010’s new debugging features.  This stuff is hard to showcase, but I believe it’s truly breakthrough technology: imagine being able to step backwards in time to see what might have caused a bug.  Cool?  Now imagine being able to do that, even if you weren’t the tester and weren’t present while the testing was being done.  Then imagine being able to see a video screen capture of what the tester was doing with your app when the bug occurred.  VS 2010 allows all that.  This could be the demise of the IWOMM (“it works on my machine”) syndrome. After the keynote, I asked Schmelzer if any of Microsoft’s competitors have debugging tools that come close to VS 2010’s.  His answer was an earnest “we don’t think so.”  If that’s true, that’s a big deal, and a huge advantage for developer teams who adopt it.  It will make software development much cheaper and more efficient.  Kind of like holding a launch event at the Brooklyn Marriott instead of 30 Rock in Manhattan! VS 2010 (version 10) and Office 2010 (version 14) aren’t the only new product versions Microsoft is releasing right now.  There’s also SQL Server 2008 R2 (version 10.5), Exchange 2010 (version 8, I believe), SharePoint 2010 (version 4) and, of course, Windows 7.  With so many new versions at such levels of maturity, I think it’s fair to say Microsoft has reached middle-age.  How does a company stave off a potential mid-life crisis, especially when with young Turks like Google coming along and competing so fiercely?  Hard to say.  But if focusing on core value, including value that’s hard to play into a sexy demo, is part oft the answer, then Microsoft’s doing OK.  And if some new tricks, like Windows Phone 7, can gain some traction, that might round things out nicely. Are the legacy products old tricks, or are they revised classics?  I honestly don’t know, because it’s the market’s prerogative to pass that judgement.  I can say this though: based on today’s show, I think Microsoft’s been doing its homework.

  • How to design a leaderboard?

    - by PeterK
    This sounds like an easy thing but when i considering the following Many players Some have played many games and some just started Different type of statistics ...on what information should the actual ranking be based on. I am planning to display the board in a UITableView so there is limited space available per player. However, I am not bound to the UITableView if there is a better solution. This is a quiz game and the information i am currently capturing per player is: #games played totally #games played per game type (current version have only one game type) #questions answered #correct answers Maybe i should include additional information. I have been thinking about having a leaderboard property page where the player can decide on what basis the leaderboard should display information but would like to avoid the complexity in that. However, if that is needed i will do it. Anyone that can give me some advice on how to design the presentation of this would be highly appreciated?

  • Why Wireshark does not recognize this HTTP response?

    - by Alois Mahdal
    I have a trivial CGI script that outputs simple text content. It's written in Perl and using CGI module and it specifies only the most basic headers: print $q->header( -type => 'text/plain', -Content_length => $length, ); print $stuff; There's no apparent issue with functionality, but I'm confused about the fact that Wireshark does not recognize the HTTP response as HTTP--it's marked as TCP. Here is request and response: GET /cgi-bin/memfile/memfile.pl?mbytes=1 HTTP/1.1 Host: 10.6.130.38 User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:11.0) Gecko/20100101 Firefox/11.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: cs,en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip, deflate Connection: keep-alive HTTP/1.1 200 OK Date: Thu, 05 Apr 2012 18:52:23 GMT Server: Apache/2.2.15 (Win32) mod_ssl/2.2.15 OpenSSL/0.9.8m Content-length: 1048616 Keep-Alive: timeout=5, max=100 Connection: Keep-Alive Content-Type: text/plain; charset=ISO-8859-1 XXXXXXXX...

Can somebody explain why Wireshark does not recognize it? Is there something wrong with the response?

  • What's the best way to version CSS and JS URLs?

    - by David Eyk
    As per Yahoo's much-ballyhooed Best Practices for Speeding Up Your Site, we serve up static content from a CDN using far-future cache expiration headers. Of course, we need to occasionally update these "static" files, so we currently add an infix version as part of the filename (based on the SHA1 sum of the file contents). Thus: styles.min.css Becomes: styles.min.abcd1234.css However, managing the versioned files can become tedious, and I was wondering if a GET argument notation might be cleaner and better: styles.min.css?v=abcd1234 Which do you use, and why? Are there browser- or proxy/cache-related considerations that I should consider?

  • Seeking some advice on pursuing MS in CS from Stanford or Carnegie Mellon or Caltech

    - by avi
    What kinds of projects are given preference in top notch colleges like Stanford, Caltech, etc to get admission into MS programme in Computer Science? I have an average academic portfolio. I'm pursuing Btech from a not so popular university in India with an aggregate of 67%. I'm good at designing algorithms and possess good knowledge of core subjects but helpless with my percentage. So, I think the only way I can impress them is with my project(s). Can anyone please suggest me the kinds of projects that are given preference by such top level institutes? Could you please also suggest some good projects? My area of interest would be Artificial Intelligence or any application/software/algorithm design which could be of some help to common people. Or if you have any other random idea for my project then please share it with me. Note: Web based projects and management projects like lib management wouldn't be my priority.

  • Why does qt-creator need to connect to google-analytics?

    - by Nanda
    I just installed qt-creator to work on non-qt C++ projects. The installed version is 2.5.0 (Based on Qt 4.8.2 32-bit) If I click on any of these pages: I get this error: I realized that /etc/hosts file has the following entry: 127.0.0.1 www.google-analytics.com I don't want to remove the entry from the hosts file because it's always been there along with thousands of other similar adservices/porn/malware addresses. I do not intend to say that qt-creator is looking to create problems in my computer, but I am genuinely interested to know why qt-creator needs to connect to google-analytics? Can this be disabled and qt-creator can still be functional?

  • Tiny Wings - Placing items

    I'm currently developing a Flash game like 'Tiny Wings'. I have a lot of work done, but i'm currently working on placing the items ( coins and obstacles ) on the terrain. My player it is moving on a auto-generated terrain (based on Emanuele Feronato's tutorials) so every time the player's x position is greater than (screenWidth + x) another hill is generated and so on. I'm currently having problems placing the items in a correct angle and put 5 or more items together on a hill. Could you please help me with this? Thanks, Regards.

  • AndEngine Sprite position

    - by Kirill Kulakov
    I had noticed the AndEngine a few days ago, and I tried to create basic game with a few Sprites.Sure, the engine makes the development process much more easier.However I found the sprite lacking a major functionally: Whenever there is a need to refer to the position of an Sprite the engine manipulates the position based on the top-left corner of sprite,this is not the best thing because there is a need to subtract/add the width/height to its position in order to refer to its center.However when we refer to he scale of the Sprite it scaled according to its center point (which is great) I find it very confusing to refer to its position each time differently.I solved that by extending the Sprite class and implementing my methods of setCenter and getCenter, I guess that not the best way to do so. Do you have any suggestion?

  • Asynchronous update design/interaction patterns

    - by Andy Waite
    These days many apps support asynchronous updates. For example, if you're looking at a list of widgets and you delete one of them then rather than wait for the roundtrip to the server, the app can hide the one you deleted, giving immediate feedback. The actual deletion on the server will happen in the background. This can be seen in web apps, desktop apps, iOS apps, etc. But what about when the background operation fails. How should you feed back to the user? Should you restore the UI to the pre-deletion state? What about when multiple background operations fail together? Does this behaviour/pattern have a name? Perhaps something based on the Command pattern?

  • Is my webserver being abused for banking fraud?

    Since a few weeks i'm getting a lot of 403 errors from apache in my log files that seem to be related to a bank frauding scheme.

I suspect not, because it's giving 403 to all requests. But any extra checks that I can do to ensure that my server is not being abused are welcome. I'm also curious on how the "bad guys" expected my server to behave. I.e. are they just expecting my server to act as a proxy to hide the ip of the fake site, or are they expecting that my server will actually serve the fake banking website? Is the ip 1.2.3.4 more likely to be the ip of a victim or the ip of a bad guy. I suspect a bad guy, because it's quite unlikely that a real person would visit 4 bank sites in a second. If it's from a bad guy I'm very curious at what he is trying to do.

  • Are keyboard layouts inherently flawed for programmers?

    - by Craige
    Lately I've been noticing my keyboard usage more and more and how it affects my productivity. It brought to mind a question/problem that I believe has not been truly solved in the programming community (partially based on individual preferences). Are all/most keyboard layouts inherently flawed for programmers? What changes to your keyboard layout do you feel would increase your productivity most? Edit Remember when answering that there are a number of different factors that could make a keyboard layout flawed. For instance, if you type as fast as you believe you need to, but hitting common keys is uncomfortable, said keyboard layout could be considered flawed.
