• Site returning 404 header to google, not sure why

  - by Damon

  A Drupal site that works fine for regular users returns a 404 not found error when I try to use the W3C validator on it; it is also not being indexed by google at all (which is the main issue but I suspect there is a connection). It is a https:// site with .htaccess rule to redirect any http:// request to the https://. I had had it running in google webmaster tools and thought it was fine, but it turns out I had not added the https domain. After adding the https domain it's also returning the header as HTTP/1.1 404 Not Found Date: Mon, 15 Oct 2012 19:37:43 GMT Server: Apache Expires: Sun, 19 Nov 1978 05:00:00 GMT Cache-Control: no-cache, must-revalidate, post-check=0, pre-check=0 Robots.txt just has User-agent: * Crawl-delay: 10 # Files Disallow: /cron.php How can I check what the issue is here?

• How do you usually manage callbacks in Java using Swing library?

  - by none

  I'm quite new to the Java Swing programming, and GUI development as well. As a beginner, I'm currently reading Design Pattern, but finding what I'm looking for is quite hard, most of the times. So far, I've never had huge problems defining a view hierarchy - I just use to subclass component from component. But the hard-to-do here is how managing callbacks, which often become hard to maintain due to the hard code. During my last projects, I tried to separate GUI, Listener and Callbacker objects which cooperated together, but in this way it was really hard adding new features. So, which kind of best patterns or best practices do you tend to use when trying to maintain, add new features or even worst avoid to hard-code classes which manage callbacks method in this kind of frameworks (mainly Java Swing)?

• 12.04 monitor brightness commands ignored

  - by jarvisschultz

  I cannot change the brightness of the monitor on a laptop either from the command line or from keyboard shortcuts. I have verified that the file in /sys/class/backlight/acpi_video0/brightness is changing. I have also verified that I am running the nvidia drivers. Things I have tried: Adding entries to /etc/default/grub The GRUB_CMDLINE_LINUX_DEFAULT and GRUB_CMDLINE_LINUX entries now read GRUB_CMDLINE_LINUX_DEFAULT="quite nosplash acpi_backlight=vendor" GRUB_CMDLINE_LINUX="noapic" I have also tried various commands here (with an update grub and reboot each time) but nothing has helped I enabled brightness control in /etc/X11/xorg.conf so that it now looks like Section "Device" Identifier "Default Device" Driver "nvidia" Option "NoLogo" "True" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection Investigated installing linux-kamal-mjgbacklight and determined it was not applicable to my system Nothing seems to have made any difference. I am using an Nvidia GeForce GT 330M with driver version 295.40. Does anyone have any other suggestions?

• Should I pass an object into a constructor, or instantiate in class?

  - by Prisoner

  Consider these two examples: Passing an object to a constructor class ExampleA { private $config; public function __construct($config) { $this->config = $config; } } $config = new Config; $exampleA = new ExampleA($config); Instantiating a class class ExampleB { private $config; public function __construct() { $this->config = new Config; } } $exampleA = new ExampleA(); Which is the correct way to handle adding an object as a property? When should I use one over the other? Does unit testing affect what I should use?

• What Design Pattern is separating transform converters

  - by RevMoon

  For converting a Java object model into XML I am using the following design: For different types of objects (e.g. primitive types, collections, null, etc.) I define each its own converter, which acts appropriate with respect to the given type. This way it can easily extended without adding code to a huge if-else-then construct. The converters are chosen by a method which tests whether the object is convertable at all and by using a priority ordering. The priority ordering is important so let's say a List is not converted by the POJO converter, even though it is convertable as such it would be more appropriate to use the collection converter. What design pattern is that? I can only think of a similarity to the command pattern.

• Dell L501X Display Port Screen issue

  - by jdflorezPA

  I got a Dell XPS L501X with a mini display port to VGA connector for my External Screen. On Displays it shows me: Acer Technologies 24" (which is the monitor) but only lets me up to 1024x768 resolution (The native resolution of this monitor is 1920x1200). I tried adding a new mode with xrandr, but when I applied it, it reverted back to 1024x768. As far as I know, the display port is controlled by the Intel card, right? Any ideas or suggestions would be appreciated. Thanks Using Ubuntu 11.10 32bit

• Which app can I use for easily annotating pictures/screenshots?

  - by koushik

  Often I need to annotate (draw some arrows, lines, basic shapes like squares, ellipses etc and enter some text) on top of pictures (JPG, PNG images) and screenshots (again png images). I would also need to be able to crop, resize etc. I tried the Gimp but I could only enter text and perform all image transformations but couldn't find a way to draw boxes etc. I finally settled to Openoffice.org draw, but I know that isn't what I want, because in oodraw I need to insert my pic into a drawing and resize it (or the drawing) to fit and then go about making changes and finally export to png... Is there any image editor that allows adding shapes and text to jpg & png files and save the modified file in its place? If the tool can also have template collections (like dia does) for shapes that is an added bonus.

• How can you build a C++ library to produce a .lib file for use in another project?

  - by Codereview

  I tried to use Cmake for the first time, I tried adding a library to my project (Specifically, PhysFS) but then I understood that the library had no .lib file or .a file at all, so I have to build those somehow. I have no clue where to even start around going this, what should I do? Someone suggested I'd go to the project folder and type "Cmake ..." then "Make ..." but I was clueless as to how I'd do that. How would I build the library headers and source files in a .lib file that I can link in C::B? I'm using Windows XP SP3

• Issue with permanent redirect implementation

  - by Argoron

  I have a tricky problem related to 301 redirections I badly need help with. I tried to implement these via .htaccess, but ran into trouble. The start of my .htaccess looks like this: SetEnv PHP_VER 5 Options +FollowSymlinks RewriteEngine on # Redirect non-www to www RewriteCond %{HTTP_HOST} !^(www\.|$) [NC] RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L] #--- GENERAL --- RewriteRule ^index\.html$ index.php [L] ... When I try to put a permanent redirect to index.php by adding R=301 in the square brackets, I get a 404, and I have no idea where the error comes from.

• Developing gnome shell extensions with eclipse as a IDE

  - by GAP

  I would like to know whether any body has used Eclipse JavaScript support for developing gnome-exensions. Actually aiming here for the context support which is available in eclipse. And i though if i could add all the java scripts that a extension is inheriting (base scrips) in to a user library, then i could included it as a dependency in my extension project. Have any once done this already ? Does all the methods that are used in a exentions exist in the base scripts ? In what directories does the base scripts exist ? So far i tried adding the scripts in the following directory but still i have error when i try to look at the journal gnome extension code. /usr/share/gnome-shell/js /usr/share/gjs-1.0 Thanks

• Does the user agent in any regular browser contain 'bot' or 'crawl'?

  - by Echo

  Does the user agent in any regular browser contain 'bot' or 'crawl'? I check the user agent on my site to see if it is coming from a bot or not. If it is, I can do some little optimizations since they don't login. (I don't change the content at all) After adding checks for 30-40+ bots, I'm getting tired of added them. So I was wondering if checking if it just contains 'bot' or 'crawl'. I know that wont get all bots, but it would get a lot of them. But if that could cause any false positives, then it would totally mess up the ability to add to cart, place an order, and login in.

• Where to start when digging into an existing J2EE codebase?

  - by Jacob Krustchinsky

  I work for a company that produces enterprise applications to be used by schools and districts to manage all of their tests and standards data. Their existing application is written in J2EE and is very large. I personally am a seasoned PHP and Ruby = RoR developer and I have been asked to attempt to implement easily added but crucial features to an existing J2EE codebase. I am very familiar with Java SE and know the architecture of a web application well. What I am asking for is, will this suffice for the task ahead and what tips can you give me in digging into the code base and actually efficiently adding these new features? Is there anything important I need to know before beginning and what can I expect in terms of problems and issues coming from a Java SE, PHP, RoR background? Time isn't too much of an issue, I should have plenty of time to familiarize myself with J2EE.Please also note, syntax will not be a problem here.

• Has the Appindicator or GtkMenu API changed in Saucy?

  - by marxjohnson

  I've written a custom application indicator, which isn't working properly on saucy. The menu is initialised with a few items, then updates regularly, adding or removing menu items. This worked fine <13.10, but on 13.10, the line that adds the menu to the indicator produces the following warning: Warning: /build/buildd/glib2.0-2.38.0/./gobject/gsignal.c:2475: signal 'child-added' is invalid for instance '0x24390e0' of type 'GtkMenu' self.ind.set_menu(self.menu) And the items added to the menu subsequently dont appear. A bug has been filed against several indicators for the same problem, but it's not clear to me whether this is a problem with the indicators as a result of an API change, or a bug in the GTK or Appindicator libraries. Does anyone know?

• Targeting a vehicle with complex movement?

  - by e100

  Targeting a vehicle with known constant velocity is simple, and collision is guaranteed. Imprecise AI can be modeled by adding a small error factor. But how would one go about targeting a vehicle whose movements are more complex? Perhaps it's evading the AI or another game object. I've been thinking about how I'd do it myself in a FPS (in which bullets have finite speed) and think there might need to be at least couple of targeting modes based on the target's movement in the previous second or so: If it's near linear (peak acceleration in a certain range) target with the linear model If it's highly irregular (perhaps size of bounding box of recent positions could be used?) , target at an average For now I can assume 2d space, AI is stationary and projectile moves linearly.

• Moving a LAMP set up from 32 bit to 64 bit

  - by user10157

  Hello everyone... I have setup an Ubuntu server 10.10 32bit on an old Dell D610 Laptop for testing. I have the latest PHP, MySQL and Apache with Wordpress installed. After the testing is over and once I finish adding material to my wordpress I will build a Ubuntu 10.10 64bit VM on Hyper-V. What I am wondering is , if it's best practice to build everything from scratch (which will take me more time and would like to avoid) or transfer the database and all other settings? If I choose to transfer how and what I need to do? Here's where I'd like some help as I am still an intermediate admin (If I can call it that!) I am looking forward for your help. Thanks!

• Organizing your Data Access Layer

  - by nighthawk457

  I am using Entity Framework as my ORM in an ASP.Net application. I have my database already created so ended up generating the entity model from it. What is a good way to organize files/classes in the data access layer. My entity framework model is in a class library and I was planning on adding additional classes per Entity(i.e per database table) and putting all the queries related to those tables in their respective classes. I am not sure if this is a right approach and if it is then where do the queries requiring data from multiple tables go? Am I completely wrong in organizing my files based on entities/tables and should I organize them based on functional areas instead.

• Is there ever a time when creating a level/world editor with your game is a bad idea?

  - by Borgel

  I have created a few smaller games on my own in the past. My approach has always been to create a completed editor where it has all the functionality needed to save a level file and load it into the game. This has always made most sense to me but I keep hearing from people that a game is never fully done in the editor. I have never worked in a game development team and so I don't have first hand experience, but not adding everything needed to make the game to the editor just seams wrong. Am I missing something? Is there ever a reason not to add a tool to the editor?

• best way of rendering more 3D models in three.js that not slow down page?

  - by GDevLearner

  I am in the way of creating a 3D web game using threeJS library. This is a multi-player game that players are 3D human models in game, and I need to add a human 3D model for each player that enters the game. Additionally, I want to animate the humans while they walking, but the problem, here is that adding a 3D model and animating that for each player will slow down the game or maybe cause the browser to crash. question: what is the better way of showing and animating the player's models that will not slow down the game?

• RadGrid Column Sizing

  - by Bunch

  I came across this column sizing weirdness the other day. Using a RadGrid the headers looked great. The rows with the data however sized however they felt like it, usually way too small. After looking around I came across this that solved my problem. Adding the meta tag of <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> in the head section of my aspx page was what I needed. My issue was pretty specific since I had to target IE8 for the app I was working on but it may apply to other scenarios as well. Tags: ASP.Net

• When do I bite the bullet and hire a developer? [closed]

  - by Paul Seattle

  I have an awesome URL, I've had it since the mid 90's, and up until around 2002 I was having an awesome time writing music reviews and features into static pages and adding their URL to static index pages and everything was just great. Then things got complicated really fast, and for one reason or another I handed the site over to a very talented friend who turned it into a db based site run by cf. Now, here I am around twelve years later putting it all back together using mysql, php and css on a need-to-learn basis and even though I'm sooo close to where I want it to be I realize, erm, it should have been written using mysqli etc etc ad infinitum. So I'm wondering at what point do I just give in and hire a developer to take over, how much does it even cost, and how do I know I'm working with someone who is better than I am?

• How can I pull data from PeopleSoft on demand?

  - by trpt4him

  I work in IT at a university and I'm working with about 5 different departments to develop a new process for students to apply to a specific school within the university (not the university as a whole). We're using a web-based college application vendor and adding the applicant questions for the school itself to the main university application. Currently the main application feeds into PeopleSoft. The IT staff here is building a new table to hold just our school's applicant data. I want to be able to access that data from PeopleSoft for use in external applications, but our IT staff doesn't really seem to understand what I'm requesting, as they simply tell me I can have access to the PS query tools. The problem is, I don't want to run just ad hoc queries, I want to be able to connect from outside PeopleSoft and show current data within the external app. I am unable to find documentation or get a clear answer to my question. Does PeopleSoft support access via a web services API or anything similar, and does that sound like the right direction for me to take?

  I am using xcart. In the checkout process, skip the step that appears after a customer clicks the add to cart button on the product page.
