• Triangle - Rectangle Intersection in 2D

  - by Kevin Boyd

  I had previously asked this for 3D but now I changed my strategy and would like to do the intersection in 2D. The Rectangle is axis aligned and will always be in a fixed position, and has a constant shape and size, basically I want to clip the red areas of the triangles that extend outside the bounds of the rectangle The triangles could be in any position, shape or size, I my code I have a loop where I check the triangles one by one however I am still clueless about the math. I have identified 5 cases of triangle rectangle intersection as shown here. How do I find the intersection points of the triangle and the rectangle?

• Isometric drawing "Not Tile Stuff" on isometric map?

  - by Icebone1000

  So I got my isometric renderer working, it can draw diamond or jagged maps...Then I want to move on...How do I draw characters/objects on it in a optimal way? What Im doing now, as one can imagine, is traversing my grid(map) and drawing the tiles in a order so alpha blending works correctly. So, anything I draw in this map must be drawed at the same time the map is being drawn, with sucks a lot, screws your very modular map drawer, because now everything on the game (but the HUD) must be included on the drawer.. I was thinking whats the best approach to do this, comparing the position of all objects(not tile stuff) on the grid against the current tile being draw seems stupid, would it be better to add an id ON the grid(map)? this also seems terrible, because objects can move freely, not per tile steps (it can occupies 2 tiles if its between them, etc.) Dont know if matters, but my grid is 3D, so its not a plane with objects poping out, its a bunch of pilled cubes.

• Autostart app with proper icon in unity launcher

  - by kyleN

  One can autostart an application such that it launches on session start with an xdg desktop file in ~/.config/autostart (or /etc/xdg/autostart). But my application (a python/gtk/webkit/html5 app) when autostarted has a unity (and a unity-2d) launcher icon that is a gray question mark, even though: when I find it in dash, the dash shows the icon I specify in my main desktop file (in /usr/share/applications) when I launch it from dash, the launcher shows the icon I specify in my main desktop file when I add it as a favorite, the launcher shows the proper icon There are two cases where I get the gray question mark icon: autostart launch from terminal (this use case is not essential though and doesn't involve the desktop file anyway: but should/does ubuntu have an xdg desktop file interpreter à la #!/usr/bin/desktop or something) So: what is needed such unity (3d/2d) launcher panel shows the icon specified in an autostart desktop file?

• Is inline SQL still classed as bad practice now that we have Micro ORMs?

  - by Grofit

  This is a bit of an open ended question but I wanted some opinions, as I grew up in a world where inline SQL scripts were the norm, then we were all made very aware of SQL injection based issues, and how fragile the sql was when doing string manipulations all over the place. Then came the dawn of the ORM where you were explaining the query to the ORM and letting it generate its own SQL, which in a lot of cases was not optimal but was safe and easy. Another good thing about ORMs or database abstraction layers were that the SQL was generated with its database engine in mind, so I could use Hibernate/Nhibernate with MSSQL, MYSQL and my code never changed it was just a configuration detail. Now fast forward to current day, where Micro ORMs seem to be winning over more developers I was wondering why we have seemingly taken a U-Turn on the whole in-line sql subject. I must admit I do like the idea of no ORM config files and being able to write my query in a more optimal manner but it feels like I am opening myself back up to the old vulnerabilities such as SQL injection and I am also tying myself to one database engine so if I want my software to support multiple database engines I would need to do some more string hackery which seems to then start to make code unreadable and more fragile. (Just before someone mentions it I know you can use parameter based arguments with most micro orms which offers protection in most cases from sql injection) So what are peoples opinions on this sort of thing? I am using Dapper as my Micro ORM in this instance and NHibernate as my regular ORM in this scenario, however most in each field are quite similar. What I term as inline sql is SQL strings within source code. There used to be design debates over SQL strings in source code detracting from the fundamental intent of the logic, which is why statically typed linq style queries became so popular its still just 1 language, but with lets say C# and Sql in one page you have 2 languages intermingled in your raw source code now. Just to clarify, the SQL injection is just one of the known issues with using sql strings, I already mention you can stop this from happening with parameter based queries, however I highlight other issues with having SQL queries ingrained in your source code, such as the lack of DB Vendor abstraction as well as losing any level of compile time error capturing on string based queries, these are all issues which we managed to side step with the dawn of ORMs with their higher level querying functionality, such as HQL or LINQ etc (not all of the issues but most of them). So I am less focused on the individual highlighted issues and more the bigger picture of is it now becoming more acceptable to have SQL strings directly in your source code again, as most Micro ORMs use this mechanism. Here is a similar question which has a few different view points, although is more about the inline sql without the micro orm context: http://stackoverflow.com/questions/5303746/is-inline-sql-hard-coding

• "Never hide" Unity launcher via CCSM & gconf doesn't work

  - by Jim Holman

  All: I am running Unity 3D and I want to set my launcher to never hide. I first ran ccsm, and set "Hide Launcher" to "Never". I rebooted then logged back in and it was still auto-hiding. I then ran gconf-editor, I navigated to /apps/compiz-1/plugins/unityshell/screen0/options and then set launcher_hide_mode to 0. I again rebooted and logged back in. The launcher is still auto-hiding. Checking gconf-editor, launcher_hide_mode is set to 0, but this setting isn't active however. What can I do to get the launcher to Never hide? Thanks, Jim

• BAM design pointers

  - by Kavitha Srinivasan

  In working recently with a large Oracle customer on SOA and BAM, I discovered that some BAM best practices are not quite well known as I had always assumed ! There is a doc bug out to formally incorporate those learnings but here are a few notes..  EMS-DO parity When using EMS (Enterprise Message Source) as a BAM feed, the best practice is to use one EMS to write to one Data Object. There is a possibility of collisions and duplicates when multiple EMS write to the same row of a DO at the same time. This customer had 17 EMS writing to one DO at the same time. Every sensor in their BPEL process writes to one topic but the Topic was read by 1 EMS corresponding to one sensor. They then used XSL within BAM to transform the payload into the BAM DO format. And hence for a given BPEL instance, 17 sensors fired, populated 1 JMS topic, was consumed by 17 EMS which in turn wrote to 1 DataObject.(You can image what would happen for later versions of the application that needs to send more information to BAM !).  We modified their design to use one Master XSL based on sensorname for all sensors relating to a DO- say Data Object 'Orders' and were able to thus reduce the 17 EMS to 1 with a master XSL. For those of you wondering about how squeaky clean this design is, you are right ! This is indeed not squeaky clean and that brings us to yet another 'inferred' best practice. (I try very hard not to state the obvious in my blogs with the hope that everytime I blog, it is very useful but this one is an exception.) Transformations and Calculations It is optimal to do transformations within an engine like BPEL. Not only does this provide modelling ease with a nice GUI XSL mapper in JDeveloper, the XSL engine in BPEL is quite efficient at runtime as well. And so, doing XSL transformations in BAM is not quite prudent.  The same is true for any non-trivial calculations as well. It is best to do all transformations,calcuations and sanitize the data in a BPEL or like layer and then send this to BAM (via JMS, WS etc.) This then delegates simply the function of report rendering and mechanics of real-time reporting to the Oracle BAM reporting tool which it is most suited to do. All nulls are not created equal Here is yet another possibly known fact but reiterated here. For an EMS with an Upsert operation: a) If Empty tags or tags with no value are sent like <Tag1/> or <Tag1></Tag1>, the DO will be overwritten with --null-- b) If Empty tags are suppressed ie not generated at all, the corresponding DO field will NOT be overwritten. The field will have whatever value existed previously.  For an EMS with an Insert operation, both tags with an empty value and no tags result in –null-- being written to the DO. Hope this helps .. Happy 4th!

• SPARC T3-1 Record Results Running JD Edwards EnterpriseOne Day in the Life Benchmark with Added Batch Component

  - by Brian

  Using Oracle's SPARC T3-1 server for the application tier and Oracle's SPARC Enterprise M3000 server for the database tier, a world record result was produced running the Oracle's JD Edwards EnterpriseOne applications Day in the Life benchmark run concurrently with a batch workload. The SPARC T3-1 server based result has 25% better performance than the IBM Power 750 POWER7 server even though the IBM result did not include running a batch component. The SPARC T3-1 server based result has 25% better space/performance than the IBM Power 750 POWER7 server as measured by the online component. The SPARC T3-1 server based result is 5x faster than the x86-based IBM x3650 M2 server system when executing the online component of the JD Edwards EnterpriseOne 9.0.1 Day in the Life benchmark. The IBM result did not include a batch component. The SPARC T3-1 server based result has 2.5x better space/performance than the x86-based IBM x3650 M2 server as measured by the online component. The combination of SPARC T3-1 and SPARC Enterprise M3000 servers delivered a Day in the Life benchmark result of 5000 online users with 0.875 seconds of average transaction response time running concurrently with 19 Universal Batch Engine (UBE) processes at 10 UBEs/minute. The solution exercises various JD Edwards EnterpriseOne applications while running Oracle WebLogic Server 11g Release 1 and Oracle Web Tier Utilities 11g HTTP server in Oracle Solaris Containers, together with the Oracle Database 11g Release 2. The SPARC T3-1 server showed that it could handle the additional workload of batch processing while maintaining the same number of online users for the JD Edwards EnterpriseOne Day in the Life benchmark. This was accomplished with minimal loss in response time. JD Edwards EnterpriseOne 9.0.1 takes advantage of the large number of compute threads available in the SPARC T3-1 server at the application tier and achieves excellent response times. The SPARC T3-1 server consolidates the application/web tier of the JD Edwards EnterpriseOne 9.0.1 application using Oracle Solaris Containers. Containers provide flexibility, easier maintenance and better CPU utilization of the server leaving processing capacity for additional growth. A number of Oracle advanced technology and features were used to obtain this result: Oracle Solaris 10, Oracle Solaris Containers, Oracle Java Hotspot Server VM, Oracle WebLogic Server 11g Release 1, Oracle Web Tier Utilities 11g, Oracle Database 11g Release 2, the SPARC T3 and SPARC64 VII+ based servers. This is the first published result running both online and batch workload concurrently on the JD Enterprise Application server. No published results are available from IBM running the online component together with a batch workload. The 9.0.1 version of the benchmark saw some minor performance improvements relative to 9.0. When comparing between 9.0.1 and 9.0 results, the reader should take this into account when the difference between results is small.

Oracle offers 70 JD Edwards EnterpriseOne application modules to support a diverse set of business operations. Oracle's Day in the Life (DIL) kit is a suite of scripts that exercises most common transactions of JD Edwards EnterpriseOne applications, including business processes such as payroll, sales order, purchase order, work order, and other manufacturing processes, such as ship confirmation. These are labeled by industry acronyms such as SCM, CRM, HCM, SRM and FMS. The kit's scripts execute transactions typical of a mid-sized manufacturing company. The workload consists of online transactions and the UBE workload of 15 short and 4 long UBEs. LoadRunner runs the DIL workload, collects the user’s transactions response times and reports the key metric of Combined Weighted Average Transaction Response time. The UBE processes workload runs from the JD Enterprise Application server. Oracle's UBE processes come as three flavors: Short UBEs < 1 minute engage in Business Report and Summary Analysis, Mid UBEs > 1 minute create a large report of Account, Balance, and Full Address, Long UBEs > 2 minutes simulate Payroll, Sales Order, night only jobs. The UBE workload generates large numbers of PDF files reports and log files. The UBE Queues are categorized as the QBATCHD, a single threaded queue for large UBEs, and the QPROCESS queue for short UBEs run concurrently. One of the Oracle Solaris Containers ran 4 Long UBEs, while another Container ran 15 short UBEs concurrently. The mixed size UBEs ran concurrently from the SPARC T3-1 server with the 5000 online users driven by the LoadRunner. Oracle’s UBE process performance metric is Number of Maximum Concurrent UBE processes at transaction rate, UBEs/minute. Key Points and Best Practices Two JD Edwards EnterpriseOne Application Servers and two Oracle Fusion Middleware WebLogic Servers 11g R1 coupled with two Oracle Fusion Middleware 11g Web Tier HTTP Server instances on the SPARC T3-1 server were hosted in four separate Oracle Solaris Containers to demonstrate consolidation of multiple application and web servers.

  - by StefanE

  Possible Duplicate: How do I build a 2D physics engine? If we take the game Angry Birds that had big success lately I were thinking how do they implement the physics in a game like that? Your are shooting of your birds and they hit something that will fall off and in turn creating a chain reaction of things either falling or exploding.. Are all this happening with calculations with rules considering all collisions together with gravity etc.?

• Corrupt plymouth boot screen when using properietary Nvidia drivers

  - by Tejas Hosangadi

  I recently got the final version of Ubuntu Natty Narwhal x64 and everything is working just fine. The only thing I am having trouble with is the boot screen. After I installed the proprietary nVidia drivers, the boot screen becomes corrupt and only shows text (as it has been doing since Ubuntu 10.04). When I followed the instructions to fix the boot screen in 10.04 and 10.10, the boot screen still remains the same and the problem isn't resolved. Please give a full guide on how to fix this problem. Machine Details Computer : HP Pavilion p6240in Processor : Core 2 duo Memory : 4096 megabytes Graphics : nVidia G210 3d graphics Monitor : Dell 17 inch lcd Another question I would like to ask is whether it is possible to use this script (http://www.webupd8.org/2010/10/script-to-fix-ubuntu-plymouth-for.html) with 11.04. I am asking this question because it says that the script works only with 10.04 and 10.10.

• What's new in the RightNow November 2012 release?

  - by Richard Lefebvre

  What new in the RightNow November 2012? In order to find out, please watch this tutorial with imbedded demonstration or read the November 2012 Release notes.   News Facts The November 2012 release of     Oracle’s RightNow CX Cloud Service marks the completion of development efforts for 2012 and continues Oracle’s commitment to enhancing the Oracle RightNow offering following the acquisition. New release delivers key capabilities designed to help organizations improve customer experiences in order to increase customer acquisition and retention, while reducing total cost of ownership. Part of the Oracle Cloud, Oracle RightNow CX Cloud Service now integrates Oracle RightNow Chat Cloud Service with Oracle Engagement Engine Cloud Service, helping organizations intelligently and proactively engage with customers through the right channel at the right time. Chat solutions have emerged as an important component of a cross-channel customer experience strategy. According to Forrester Research, Inc., chat adoption has risen dramatically between 2009 and 2011 from 19% to 37%, and it has the highest satisfaction level of all customer service channels at 62% satisfaction. (*) To help companies deliver enhanced customer experiences, Oracle has made significant investments in Oracle RightNow Chat Cloud Service throughout 2012. With the addition of rules-based engagement to existing capabilities such as co-browse, mobile chat, and cross-channel knowledge integration with the contact center, all delivered via the cloud, Oracle RightNow Chat Cloud Service is differentiated as the industry-leading chat solution. The Oracle Cloud offers a broad portfolio of software as-a-service applications, including Oracle Customer Service and Support Cloud Service, which is based on the Oracle RightNow CX Cloud Service. New Capabilities Key Oracle RightNow Chat Cloud Service and other cross-channel capabilities include: Chat Business Rules, with over 70 built-in rule conditions, leverage the Oracle Engagement Engine to help enable organizations capture rich visitor data and invoke complex actions and triggers. Chat Business Rules allow granular control over when to engage a customer via the chat channel based on customer behavior, customer profile information and operational information. Click-to-Call provides the option for a customer to engage with a live agent over the phone during the Web browsing experience. Chat Availability Controls provide organizations with the ability to throttle volume through the chat channel based on real-time agent availability and wait time thresholds. This ability to manage the channel more efficiently allows organizations to provide a better experience to customers using the chat channel. Strategic and Operational Chat Channel Analytics provide better insight into channel and agent productivity and utilization and effectiveness with both out-of-the-box reports and ad hoc reports. New chat channel analytics provide comprehensive metrics with full data transparency. Background Service Updates improve high availability metrics for Oracle RightNow Chat Cloud Service during service update periods, setting the industry leading standard for sales and service delivery to customers via the chat channel. Additional Capabilities include: Improved Web developer tools for more efficient self-service user interface design Improved administration for enhanced user sessions management Increased cross-channel community collaboration Enhanced extensibility widgets and syndication management Streamlined content management and analytics capabilities Read the full announcement here
