• Can a domain specific language be used to representing the Open SRD

  - by NeoModulus

  I am in the early stages of creating an open source C# library that would allow developers to drop in the open SRD (http://www.d20srd.org/) into an existing project. Abstracted it is a complex set of tightly coupled business rules. Having previously worked on an adaptive object model project for health care risk management I began with that pattern in mind. Due to the high coupling of rules it is becoming apparent that the project may require some kind of scripting. Have started researching DSL implementation I am now considering scraping the adaptive object model for a domain specific language. I have not work with domain specific languages so my question is it reasonable to assume a domain specific language can be used to representing the open SRD?

• What technology(s)would be suitable for the front end part of a Java web game?

  - by James.Elsey

  As asked in a previous question, I'm looking to create a small MMO that will be deployed onto GAE. I'm confused about what technologies I could use for the user interface, I've considered the following JSP Pages - I've got experience with JSP/JSTL and I would find this easy to work with, it would require the user having to "submit" the page each time they perform an action so may become a little clumsey for players. Applet - I could create an applet that sits on the front end and communicates to the back end game engine, however I'm not sure how good this method would be and have not used applets since university.. What other options do I have? I don't have any experience in Flash/Flex so there would be a big learning curve there. Are there any other Java based options I may be able to use? My game will be text based, I may use some images, but I'm not intending to have any animations/graphics etc Thanks

• How can I make the boostrap js carousel automatically cycle as soon as the page loads?

  - by Jonathan Larkin

  Using bootstrap.js version 2.02 I'm trying to get the Twitter Bootstrap Carousel to automatically cycle as soon as someone visits my site. Right now, the auto cycling works only after you click one of the cycle buttons at least once. I want the carousel to begin cycling at the interval right away. Does anyone know how to do this? My site is hotairraccoon.com You'll see how after you click the carousel once, it begins to cycle every 5 seconds or so, but I don't want the click to be required to reveal carousel content. Thanks!

• conditional while loop in php?

  - by julio

  I'm pretty sure there's an obvious answer for this-- hoping someone can help me-- I need to do a PHP while loop, but only if a variable is true. And I can't really put the while loop in an "if" statement, which seems like the obvious thing to do, since the code block is huge and it would be ugly and confusing. Do I need to break out the code in the loop into a function, or is there an easier way to deal with this? Here's the basic idea: if(condition){ while(another_condition){ //huge block of code loops many times } } else { // huge block of code runs once } I want the huge block of code to execute regardless of the state of the condition variable-- but only to execute once if condition is false, and execute for as long as another_condition is true if condition is true. Hope that's clear! The following code doesn't work, but gives an idea of what I want to accomplish: if(condition){ while(another_condition){ } // huge block of code if (condition){ } } // closes the while loop-- obviously throws an error though! thanks in advance.

• drop-down combo box-like functionality for queries.

  - by Frank Developer

  Is it possible to provide the following type of fuctionality with informix client tools? As the user types the first two characters of a name, the drop-down list is empty. At the third character, the list fills with just the names beginning with those three characters. At the fourth character, MS-Access completes the first matching name (assuming the combo's AutoExpand is on). Once enough characters are typed to identify the customer, the user tabs to the next field. The time taken to load the combo between keystrokes is minimal. This occurs once only for each entry, unless the user backspaces through the first three characters again. If your list still contains too many records, you can reduce them by another order of magnitude by changing the value of constant conSuburbMin from 3 to 4.

• What are the Search engine affects of registering the same domain on multiple top level domains (ie. .com, .ie, .nl etc.)?

  - by user1020317

  I'm looking to register a few more domains for my company, I have my-company.com at the moment, but now require my-company.com.au and my-company.nl and some others.. I'm running through my options and wondering what is the best.. Duplicate all the content on the .com package and make a replica at the other domains Buy the other domains but do a 301 redirect back to the .com domain. Create a full new website with different content for the new domains, thus having no text duplication We currently sell over the world so would like to raise our Search rankings in various countries, can this be done by buying the domain in the country, and if so, how will the above methods affect our search rankings. Any other suggestions are welcome!

• Zend autloading different namespaces from the same directory?

  - by Sled

  Hey guys, I have a models directory in my project, and I would like to save/files classes there with different namespaces. Example: models/User.php with classname Model_User models/Table_User.php with classname Model_Table_User For the first namespace I have this in bootstrap.php $resourceLoader->addResourceTypes(array( 'model' => array( 'namespace' => 'Model', 'path' => 'models' ) )); I can't figure out how to add the second namespace so it detects files starting with Table_ Any ideas? For now I've added a second directory named 'tables' but it's getting confusing because I have each model name twice (once in the models diretory and once in the tables directory)

• Classless tables possible with Datamapper?

  - by barerd

  I have an Item class with the following attributes: itemId,name,weight,volume,price,required_skills,required_items. Since the last two attributes are going to be multivalued, I removed them and create new schemes like: itemID,required_skill (itemID is foreign key, itemID and required_skill is primary key.) Now, I'm confused how to create/use this new table. Here are the options that came to my mind: 1) The relationship between Items and Required_skills is one-to-many, so I may create a RequiredSkill class, which belongs_to Item, which in turn has n RequiredSkills. Then I can do Item.get(1).requiredskills. This sounds most logical to me. 2) Since required_skills may well be thought of as constants (since they resemble rules), I may put them into a hash or gdbm database or another sql table and query from there, which I don't prefer. My question is: is there sth like a modelless table in datamapper, where datamapper is responsible from the creation and integrity of the table and allows me to query it in datamapper way, but does not require a class, like I may do it in sql?

• jQuery: What listener do I use to check for browser auto filling the password input field?

  - by Jannis

  Hi, I have a simple problem that I cannot seem to find a solution to. Basically on this website here: http://dev.supply.net.nz/vendorapp/ (currently in development) I have some fancy label animations sliding things in and out on focus & blur. However once the user has logged in once the browser will most likely remember the password associated with the users email address/login. (Which is good and should not be disabled.) However I run into issues triggering my label slide out animation when the browser sets the value on the #password field automatically as the event for this is neither focus nor blur. Does anyone know which listener to use to run my function when the browser 'auto fills' the users password? Here is a quick screenshot of the issue:

• MySQL/PHP: How to insert logged in user id into another table that is gathering data from a form tha

  - by Lisa

  For the first time I am needing to join information from two tables and am quite nervous about doing it without any advice first. Basically, I am building a secure site that is accessed by authorised users. I have my login table with user_id, username, password Once the user is on the site, they have the option of inputting data into another table called input. At the moment this table only captures the information that is entered, not the user_id or username of the inputter. I would like the form to be able to input the user_id and/or username from the login table into the input table. Please could somebody talk me through this process? I am sure that once this is amended, I will then be able to use the table to only allow the logged in user to access the information that he or she have inputted, is that correct? Many thanks

• Is there a database with git-like qualities?

  - by Mat

  I'm looking for a database where multiple users can contribute and commit new data; other users can then pull that data into their own database repository, all in a git-like manner. A transcriptional database, if you like; does such a thing exist? My current thinking is to dump the database to a single file as SQL, but that could well get unwieldy once it is of any size. Another option is to dump the database and use the filesystem, but again it gets unwieldy once of any size.

• Do ALL your variables need to be declared private?

  - by shovonr

  I know that it's best practice to stay safe, and that we should always prevent others from directly accessing a class' properties. I hear this all the time from university professors, and I also see this all the time in a lot of source code released on the App Hub. In fact, professors say that they will actually take marks off for every variable that gets declared public. Now, this leaves me always declaring variables as private. No matter what. Even if each of these variables were to have both a getter and a setter. But here's the problem: it's tedious work. I tend to quickly loose interest in a project every time I need to have a variable in a class that could have simply been declared public instead of private with a getter and a setter. So my question is, do I really need to declare all my variables private? Or could I declare some variables public whenever they require both a getter and a setter?

• How can a regular user be notified of a required reboot?

  - by Andre

  I am administrating multiple machines on which I am admin and the users have not admin-rights. The machines are configured to pull and install updates automatically. A new kernel will require a reboot. On Ubuntu Precise this was made visible to the user through the color change of the shutdown-menu in the upper right corner (it turned red). Now, on Ubuntu Trusty, there is not color change anymore. Also, the Update Manager will not pop up for regular users reminding them of an outstanding reboot. How can a regular user know that a reboot is required?

• Button in App on iOS 4.2 won't work properly

  - by MatthiasC

  My app, written for the iPad contains several UIButtons. One of them starts and stops an AVAudioPlayer: hitting the button once starts the player, hitting it again stops it accordingly. Rinse and repeat. This all works nicely on iOS version pre 4.2. When installing the App on an iPad with iOS 4.2, the button turns on and off the audio player exactly once, then stops working properly: after hitting the button, it turns into its selected state, but it does not start the audio player (as it should) and hitting the button again doesn't return it to its default state, either. As previously said: it's all fine and dandy pre 4.2, the problem only arises on the most current OS version. XCode 3.2.4 iPad with iOS 4.2

• What Does It Usually Mean for a Feature to be "Supported"?

  - by joshin4colours

  I'm currently working some testing for a particular area of an application. I had to write some automated tests for a particular feature but due to the circumstances, this was not easy to do. When I asked one of the other testers about it, he mentioned that the same features exist in a sister application our company produces but isn't documented anywhere (end-user documentation or otherwise). He also said that the feature doesn't typically get tested at all in the sister application and isn't usually tested in the application I work on. Apparently this feature isn't heavily used but removing it would require a fair bit of work so the benefit-cost ratio doesn't work out. All of this has left me with some questions. Other than "The documentation says so" or "We told the client it is", what usually makes a feature "supported" versus an unsupported feature?

• quickest way to research a set of pages backlinks

  - by JeremyB

  I have a list of 300+ pages (they were chosen based on which pages rank for a keyword I'm interested in) and I want to compile a list all the (known) inbound links to those pages. What's the fastest way to do this? It seems like the only tools out there-- Yahoo Site Explorer, SEOMoz, Majestic, require you to either a) manually export each set of links by hand, or b) get data at the domain level (e.g. Majestic's clique hunter). Does anyone know of any efficient way to do this? I ask because I'm about to write a bunch of code and I don't want to waste my time if there's another tool that will work. I know SEOMoz and Majestic have API's but I'm wondering if there's a more user-friendly option.

• Flash Overlapping HTML. CSS Problem In IE??

  - by Jascha

  HELP, this is a very unique problem and I can't for the life of me figure it out. My flash content is overlapping the HTML above it. This only happens if I've just launched IE after being restarted and goes away once I refresh the page. I even added a jQuery $(document).ready function that sets a margin between the html and the flash content to add 1px of space when the page is loaded. It's so hard to figure out, because once I refresh the page, it goes away. Any input GREATLY appreciated. Here is the site. http://www.californiaremodels.com (This only happens in IE) here is a screen shot of the problem.

• Making Separate Assemblies For Different Types Of Tests For The Same Component?

  - by sooprise

  I was told by a few members here that splitting up my unit tests into different assemblies for different components is the best way to structure unit tests. Now, I have a few questions about that idea. What are the advantages of this? Organization, and isolation of errors? Let's say I have a component named "calculator", and I create an assembly for the unit tests on "calculator". Would I create a separate assembly for the integration tests I want to run on "calculator"? Or is the definition of an integration test a test across multiple components, like "calculator" and whatever else, which would require a separate assembly to test both of them together? In that case, would I have one assembly to do all of the integration testing for every component combination?

• Is there an imperative language with a Haskell-like type system?

  - by Graham Kaemmer

  I've tried to learn Haskell a few times over the last few years, and, maybe because I know mainly scripting languages, the functional-ness of it has always bothered me (monads seem like a huge mess for doing lots of I/O). However, I think it's type system is perfect. Reading through a guide to Haskell's types and typeclasses (like this), I don't really see a reason why they would require a functional language, and furthermore, they seem like they would be perfect for an industry-grade object-oriented language (like Java). This all begs the question: has anyone ever taken Haskell's typing system and made a imperative, OOP language with it? If so, I want to use it.

• Static variable for optimization

  - by keithjgrant

  I'm wondering if I can use a static variable for optimization: public function Bar() { static $i = moderatelyExpensiveFunctionCall(); if ($i) { return something(); } else { return somethingElse(); } } I know that once $i is initialized, it won't be changed by by that line of code on successive calls to Bar(). I assume this means that moderatelyExpensiveFunctionCall() won't be evaluated every time I call, but I'd like to know for certain. Once PHP sees a static variable that has been initialized, does it skip over that line of code? In other words, is this going to optimize my execution time if I make a lot of calls to Bar(), or am I wasting my time?

• Looking for best approach to create new projects for enviroment specifics files

  - by Ness

  ClearCase Question... Overview of requirements: There are 3 diff environments (DEV, TEST and PROD) which have a folder called 'common' that users across all envs. There are multiple servers in those 3 envs and we want to store their server environment specific configuration files in Clearcase. The executables files are different for each environment. Thus there will not be cross delivery require between dev/test/prod. Any thoughts on how we can approach this? Is keeping it simplest is the best approach here? One component to one vobs as (DEV_Serv1, TEST_Serv1, PROD_Serv1, Dev_Serv2, Test_Serv2 and etc)? OR Have multiple components VOB? One other thing is developers here like to use snapshots views.
