  • Need Guidance Making HTML5 Canvas Game Engine

    - by Scriptonaut
    So I have some free time this winter break and want to build a simple 2d HTML5 canvas game engine. Mostly a physics engine that will dictate the way objects move and interact(collisions, etc). I made a basic game here: http://caidenhome.com/HTML%205/pong.html and would like to make more, and thought that this would be a good reason to make a simple framework for this stuff. Here are some questions: Does the scripting language have to be Javascript? What about Ruby? I will probably write it with jQuery because of the selecting powers, but I'm curious either way. Are there any great guides you guys know of? I want a fast guide that will help me bust out this engine sometime in the next 2 weeks, hopefully sooner. What are some good conventions I should be aware of? What's the best way to get sound? At the moment I'm using something like this: var audioElement = document.createElement('audio'); audioElement.setAttribute('src', 'paddle_col.wav'); audioElement.load(); I'm interested in making this engine lightweight and extremely efficient, I will do whatever it takes to get great speeds and processing power. I know this question is fairly vague, but I just need a push in the right direction. Thanks :)

  • Examples of datecentric LOB-application in Silverlight with creative design?

    - by Alexander Galkin
    I am a database developer and I have rather limited experience with interface design. I am currently working on a project in my free-time a freetime which is mostly data centric and I would like to develop an eye-catchy interface for it using Silverlight. What I am looking for are examples of nice and interesting LOB applications in Siverlight without the use of paid frameworks. So far, I could only find something like Telerik sample application, but it uses a lot of Telerik controls I can't afford to buy.

  • Translating Your Customizations

    - by Richard Bingham
    This blog post explains the basics of translating the customizations you can make to Fusion Applications products, with the inclusion of information for both composer-based customizations and the generic design-time customizations done via JDeveloper. Introduction Like most Oracle Applications, Fusion Applications installs on-premise with a US-English base language that is, in Release 7, supported by the option to add up to a total of 22 additional language packs (In Oracle Cloud production environments languages are pre-installed already). As such many organizations offer their users the option of working with their local language, and logically that should also apply for any customizations as well. Composer-based UI Customizations Customizations made in Page Composer take into consideration the session LOCALE, as set in the user preferences screen, during all customization work, and stores the customization in the MDS repository accordingly. As such the actual new or changed values used will only apply for the same language under which the customization was made, and text for any other languages requires a separate upload. See the Resource Bundles section below, which incidentally also applies to custom UI changes done in JDeveloper. You may have noticed this when you select the “Select Text Resource” menu option when editing the text on a page. Using this ensures that the resource bundles are used, whereas if you define a static value in Expression Builder it will never be available for translation. Notice in the screenshot below the “What’s New” custom value I have already defined using the ‘Select Text Resource’ feature is internally using the adfBundle groovy function to pull the custom value for my key (RT_S_1) from the ComposerOverrideBundle. Figure 1 – Page Composer showing the override bundle being used. Business Objects Customizing the Business Objects available in the Applications Composer tool for the CRM products, such as adding additional fields, also operates using the session language. Translating these additional values for these fields into other installed languages requires loading additional resource bundles, again as described below. Reports and Analytics Most customizations to Reports and BI Analytics are just essentially reorganizations and visualizations of existing number and text data from the system, and as such will use the appropriate values based on the users session language. Where a translated value or string exists for that session language, it will be used without the need for additional work. Extending through the addition of brand new reports and analytics requires another method of loading the translated strings, as part of what is known as ‘Localizing’ the BI Catalog and Metadata. This time it is via an export/import of XML data through the BI Administrators console, and is described in the OBIEE Admin Guide. Fusion Applications reports based on BI Publisher are already defined in template-per-locale, and in addition provide an extra process for getting the data for translation and reloading. This again uses the standard resource bundle format. Loading a custom report is illustrated in this video from our YouTube channel which shows the screen for both setting the template local and running an export for translation. Fusion Applications Menus Whilst the seeded Navigator and Global Menu values are fully translated when the additional language is installed, if they are customized then the change or new menu item will apply universally, not currently per language. This is set to change in a future release with the new UI Text Editor feature described below. More on Resource Bundles As mentioned above, to provide translations for most of your customizations you need to add values to a resource bundle. This is an industry open standard (OASIS) format XML file with the extension .xliff, and store translated values for the strings used by ADF at run-time. The general process is that these values are exported from the MDS repository, manually edited, and then imported back in again.This needs to be done by an administrator, via either WLST commands or through Enterprise Manager as per the screenshot below. This is detailed out in the Fusion Applications Extensibility Guide. For SaaS environments the Cloud Operations team can assist. Figure 2 – Enterprise Manager’s MDS export used getting resource bundles for manual translation and re-imported on the same screen. All customized strings are stored in an override bundle (xliff file) for each locale, suffixed with the language initials, with English ones being saved to the default. As such each language bundle can be easily identified and updated. Similarly if you used JDeveloper to create your own applications as extensions to Fusion Applications you would use the native support for resource bundles, and add them into the faces-config.xml file for inclusion in your application. An example is this ADF customization video from our YouTube channel. JDeveloper also supports automatic synchronization between your underlying resource bundles and any translatable strings you add – very handy. For more information see chapters on “Using Automatic Resource Bundle Integration in JDeveloper” and “Manually Defining Resource Bundles and Locales” in the Oracle Fusion Middleware Web User Interface Developer’s Guide for Oracle Application Development Framework. FND Messages and Look-ups FND Messages, as defined here, are not used for UI labels (they are known as ‘strings’), but are the responses back to users as a result of an action, such as from a page submit. Each ‘message’ is defined and stored in the related database table (FND_MESSAGES_B), with another (FND_MESSAGES_TL) holding any language-specific values. These come seeded with the additional language installs, however if you customize the messages via the “Manage Messages” task in Functional Setup Manager, or add new ones, then currently (in Release 7) you’ll need to repeat it for each language. Figure 3 – An FND Message defined in an English user session. Similarly Look-ups are stored in a translation table (FND_LOOKUP_VALUES_TL) where appropriate, and can be customized by setting the users session language and making the change  in the Setup and Maintenance task entitled “Manage [Standard|Common] Look-ups”. Online Help Yes, in fact all the seeded help is applied as part of each language pack install as part of the post-install provisioning process. If you are editing or adding custom online help then the Create Help screen provides a drop-down of which language your help customization will apply to. This is shown in the video below from our YouTube channel, and obviously you’ll need to it for each language in use. What is Coming for Translations? Currently planned for Release 8 is something called the User Interface (UI) Text Editor. This tool will allow the editing of all the text shown on the pages and forms of Fusion Application. This will provide a search based on a particular term or word, say “Worker”, and will allow it to be adjusted, say to “Employee”, which then updates all the Resource Bundles that contain it. In the case of multi-language environments, it will use the users session language (locale) to know which Resource Bundles to apply the change to. This capability will also support customization sandboxes, to help ensure changes can be tested and approved.  It is also interesting to note that the design currently allows any page-specific customizations done using Page Composer or Application Composer to over-write the global changes done via the UI Text Editor, allowing for special context-sensitive values to still be used. Further Reading and Resources The following short list provides the mains resources for digging into more detail on translation support for both Composer and JDeveloper customization projects. There is a dedicated chapter entitled “Translating Custom Text” in the Fusion Applications Extensibility Guide. This has good examples and steps for many tasks, especially administering resource bundles. Using localization formatting (numbers, dates etc) for design-time changes is well documented in the Fusion Applications Developer Guide. For more guidelines on general design-time globalization, see either the ‘Internationalizing and Localizing Pages’ chapter in the Oracle Fusion Middleware Web User Interface Developer’s Guide for Oracle Application Development Framework (Oracle Fusion Applications Edition) or the general Oracle Database Globalization Support Guide. The Oracle Architecture ‘A-Team’ provided a recent post on customizing the user session timeout popup, using design-time changes to resource bundles. It has detailed step-by-step examples which can be a useful illustration.

  • Apache proxy pass in nginx

    - by summerbulb
    I have the following configuration in Apache: RewriteEngine On #APP ProxyPass /abc/ http://remote.com/abc/ ProxyPassReverse /abc/ http://remote.com/abc/ #APP2 ProxyPass /efg/ http://remote.com/efg/ ProxyPassReverse /efg/ http://remote.com/efg/ I am trying to have the same configuration in nginx. After reading some links, this is what I have : server { listen 8081; server_name localhost; proxy_redirect http://localhost:8081/ http://remote.com/; location ^~/abc/ { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://remote.com/abc/; } location ^~/efg/ { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://remote.com/efg/; } } I already have the following configuration: server { listen 8080; server_name localhost; location / { root html; index index.html index.htm; } location ^~/myAPP { alias path/to/app; index main.html; } location ^~/myAPP/images { alias another/path/to/images autoindex on; } } The idea here is to overcome a same-origin-policy problem. The main pages are on localhost:8080 but we need ajax calls to http://remote.com/abc. Both domains are under my control. Using the above configuration, the ajax calls either don't reach the remote server or get cut off because of the cross origin. The above solution worked in Apache and isn't working in nginx, so I am assuming it's a configuration problem. I think there is an implicit question here: should I have two server declarations or should I somehow merge them into one? EDIT: Added some more information EDIT2: I've moved all the proxy_pass configuration into the main server declaration and changed all the ajax calls to go through port 8080. I am now getting a new error: 502 Connection reset by peer. Wireshark shows packets going out to http://remote.com with a bad IP header checksum.

  • DotNetNuke + PayPal

    - by Nuri Halperin
    A DotNetNuke i'm supporting has had a paypal "buy now" button and other variations with custom fields for a while now. About 2 weeks ago (somewhere in March 2010) they all stopped working. The problem manifested such that once you clicked the "buy now" button, Paypal site would throw a scary error page to the effect of: "Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log" Once I verified no cheeky content editor changed the page, I went digging for answers. The main source incompatibility of PayPal's simple HTML forms is that DNN includes a form on every page, and nested forms are not really supported. As blogged here and lamented here, the solution I came up with is simply to modify the form enctype to 'application/x-www-form-urlencoded' as illustrated below: 1: <input type="image" border="0" 2: src="https://www.paypal.com/en_US/i/btn/btn_buynowCC_LG.gif" 3: name="submit" 4: alt="PayPal - The safer, easier way to pay online!" 5: onClick="this.form.action='https://www.paypal.com/cgi-bin/webscr'; this.form.enctype='application/x-www-form-urlencoded';this.form.submit();" /> One would think that PayPal would want the masses submitting HTML in all manners of "enctype", but I guess every company has it's quirks. At least my favorite non-profit can now continue and accept payments. Sigh.

  • Trying to script rsync using pam_exec

    - by Ricky-Rose
    I'm trying to write a bash script that will execute rsync when called by pam_exec. I've tried a couple different ways, and I'm not sure what I'm doing wrong. When I try to run the script at login by adding session optional pam_exec.so /usr/bin/local/sync.sh to my sshd file, it gives me an exit code of 12. if I log in and then manually run my script, it allows me to connect to the remote server, and it lists my files, but it doesn't actually sync anything. I have tried the code below using buth $USER and $PAM_USER. $PAM_USER doesn't work at all. #!/bin/sh rsync -azv -e ssh $USER@remote_server:/home/html/$USER/ /home/html/$USER

  • Importing Delicious export into Firefox 3

    - by Jordan Reiter
    The HTML export file from Delicious creates an HTML file that, while importable into Firefox, loses all of the tags, which pretty much misses the point of delicious. Every link I've found to do the import doesn't work: The online converter Delicious-to-Firefox 3 keeps throwing a server error; the "better" version is down I tried using the trick of syncing Delicious bookmarks to Flock and then restoring that file to my Firefox browser. Although the bookmarks are in Firefox, they don't show up anywhere. I know they're in Firefox because when I create a backup file, they're in the JSON file but they refuse to show in the browser anywhere (clicking on any tag shows an empty list) Basically, I'm looking for someone who has successfully imported their delicious bookmarks, with tags, into Firefox 3.6.13 (Mac).

  • Use of c89 in GNU software

    - by Federico Culloca
    In GNU coding standard it is said that free software developer should use C89 because C99 is not widespread yet. 1999 Standard C is not widespread yet, so please do not require its features in programs. Reference here. Are they talking about developers knowledge of C99, or about compilers supporting it? Also, is this statement plausible as of today or is it somewhat "obsolete" or at least obsolescent.

  • PHP at the root directory using Ngnix on Linode and Ubuntu 12.04

    - by Steve Kinney
    I originally set up my Linode to use it with the Sinatra applications using Phusion Passenger that I was developing and I have it working great for that. However, as time goes on, I find myself needing just a wee bit of PHP to do a server-side thing here or there. My basic set up was based off of this Linode recipe (I copied and pasted the parts that I needed—I did not install Redis and Node). If I go to http://scholarsnyc.com/index.php everything works great. If I just go the base URL however, I get a 403 Forbidden error (I have a vanilla HTML page there for now). I've played with file permissions and the same file will work if I call it directly. I've done my homework and nothing I try seems to work. I'm sure there is an obvious error. I'm also sure that there are some rookie mistakes in my Nginx configuration (some of those mistakes are the artifacts of trying different fixes from my research. user www-data www-data; worker_processes 1; events { worker_connections 1024; } upstream php { server 127.0.0.1:9001; } http { passenger_root /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.12; passenger_ruby /usr/local/bin/ruby; include mime.types; default_type application/octet-stream; index index.php index.html index.htm; sendfile on; keepalive_timeout 65; server { server_name localhost scholarsnyc.com www.scholarsnyc.com; root /srv/www/scholarsnyc.com/public; location / { index index.php; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } server { server_name data.scholarsnyc.com; root /srv/www/data.scholarsnyc.com/public; passenger_enabled on; } server { server_name tech.scholarsnyc.com; root /srv/www/tech.scholarsnyc.com/public; location / { root /srv/www/tech.scholarsnyc.com/public; index index.php index.html index.htm; } } } Any other optimizations are also appreciated.

  • Making large scale changes to an economy in a social game

    - by Zach
    Are there any examples or case studies of social games, specifically on Facebook, where the developer has made drastic changes to the economy? I'm specifically interested in examples where the old economy was based off of purchasing items with Facebook credits then moving to a new model where the same inventory or similar inventory is sold with a soft currency. The closest comparisons I've been able to find so far are looking at iOS games that have gone from purchase models to freemium models, but haven't found a comparable scenario in a social game besides larger scale MMO's.

  • K-12 and Cloud considerations

    - by user736511
    Much like every other Public Sector organization, school districts in the US and Canada are under tremendous pressure to deliver consistent and modern services while operating with reduced budgets, IT personnel shortages, and staff attrition.  Electronic/remote learning and the need for immediate access to resources such as grades, calendars, curricula etc. are straining IT environments that were already burdened with meeting privacy requirements imposed by both regulators and parents/students.  One area viewed as a solution to at least some of the challenges is the use of "Cloud" in education.  Although the concept of "Cloud" is nothing new in education with many providers supplying educational material over the web, school districts defer previously-in-house-hosted services to established commercial vendors to accommodate document sharing, app hosting, and even e-mail.  Doing so, however, does not reduce an important risk, that of privacy.  As always, Cloud implementations are viewed in a skeptical manner because of the perceived reduction in sensitive data management and protection thereof, although with a careful approach and the right tooling, the benefits realized by Clouds can expand to security and privacy.   Oracle's comprehensive approach to data privacy and identity management ensures that the necessary tools are available to support regulations, operational efficiencies and strong security regardless of where the sensitive data is stored - on premise or a Cloud.  Common management tools, role-based access controls, access policy management and engineered systems provided by Oracle can be the foundational pieces on which school districts can build their Cloud implementations without having to worry about security itself. Their biggest challenge, and it is a positive one, is how to best take advantage of Oracle's DB Security and IDM functionality to reduce operational costs while enabling modern applications and data delivery to those who needs access to it.

  • Android game development in c++

    - by kamziro
    So being a primarily c/c++ developer, I've always thought that the only option for mobile game development for me was using iOS, which allows for c/c++ (and minimising objective C). I heard from a friend though, that android has a native development toolkit which allows for c++ code to work on android. Has anyone used this, and if so, how do you find it? I mean, will it "just work" like iOS, or are there more considerations that need to be taken care of due to the wide variety of android devices available?

  • How do I learn to develop financial software?

    - by Jack Smartie
    I would like to know what I have to learn to become a financial software developer in the area of brokerage/investment software. I apologize if this question is off topic. I'm not sure where to put it. What programming language(s) is most commonly used in the financial world? Financial software requires highly accurate and redundant features. Are these programming skills learned through experience, a class, or a book?
