• What types of programming contest problems are there?

  - by Alex

  Basically, I want to make a great reference for use with programming contests that would have all of the algorithms that I can put together that I would need during a contest as well as sample useage for the code. I'm planning on making this into a sort of book that I could print off and take with me to competitions. I would like to do this rather than simply bringing other books (such as Algorithms books) because I think that I will learn a lot more by going over all of the algorithms myself as well as I would know exactly what I have in the book, making it more efficient to have and use. So, I've been doing research to determine what types of programming problems and algorithms are common on contests, and the only thing I can really find is this (which I have seen referenced a few times): Hal Burch conducted an analysis over spring break of 1999 and made an amazing discovery: there are only 16 types of programming contest problems! Furthermore, the top several comprise almost 80% of the problems seen at the IOI. Here they are: Dynamic Programming Greedy Complete Search Flood Fill Shortest Path Recursive Search Techniques Minimum Spanning Tree Knapsack Computational Geometry Network Flow Eulerian Path Two-Dimensional Convex Hull BigNums Heuristic Search Approximate Search Ad Hoc Problems The most challenging problems are Combination Problems which involve a loop (combinations, subsets, etc.) around one of the above algorithms - or even a loop of one algorithm with another inside it. These seem extraordinarily tricky to get right, even though conceptually they are ``obvious''. Now that's good and all, but that study was conducted in 1999, which was 13 years ago! One thing I know is that there are no BigNums problems any more (as Java has a BigInteger class, they have stopped making those problems). So, I'm wondering if anyone knows of any more recent studies of the types of problems that may be seen in a programming contest? Or what the most helpful algorithms on contests would be?

• Good Laptop .NET Developer VM Setup

  - by Steve Brouillard

  I was torn between putting this question on this site or SuperUsers. I've tried to do a good bit of searching on this, and while I find plenty of info on why to go with a VM or not, there isn't much practical advise on HOW to best set things up. Here's what I currently HAVE: HP EliteBook 1540, quad-core, 8GB memory, 500GB 7200 RPM HD, eSATA port. Descent machine. Should work just fine. Windows 7 64-bit Host OS. This also acts as my day-to-day basic stuff (email, Word Docs, etc...) OS. VMWare Desktop Windows 7 64-bit Guest OS with all my .NET dev tools, frameworks, etc loaded on it. It's configured to use 2 cores and up to 6GB of memory. I figure that the dev env will need more than email, word, etc... So, this seemed like a good option to me, but I find with the VM running, things tend to slow down all around on both the host and guest OS. Memory and CPU utilization don't seem to be an issue, but I/O does. I tried running the VM on an external eSATA drive, figuring that the extra channel might pick up the slack. Things only got worse (could be my eSATA enclosure). So, for all of that I have basically two questions in one. Has anyone used this sort of setup and are there any gotchas either around the VMWare configuration or anything else I may have missed here that you can point me to? Is there another option that might work better? For example, I've considered trying a lighter weight Host OS and run both of my environments as VMs? I tried this with Server 2008 Hyper-V, but I lose too much laptop functionality going this route, so I never completed setup. I'm not averse to Linux as a host OS, though I'm no Linux expert. If I'm missing any critical info, feel free to ask. Thanks in advance for your help. Steve

• Why is testing MVC Views frowned upon?

  - by Peter Bernier

  I'm currently setting the groundwork for an ASP.Net MVC application and I'm looking into what sort of unit-tests I should be prepared to write. I've seen in multiple places people essentially saying 'don't bother testing your views, there's no logic and it's trivial and will be covered by an integration test'. I don't understand how this has become the accepted wisdom. Integration tests serve an entirely different purpose than unit tests. If I break something, I don't want to know a half-hour later when my integration tests break, I want to know immediately. Sample Scenario : Lets say we're dealing with a standard CRUD app with a Customer entity. The customer has a name and an address. At each level of testing, I want to verify that the Customer retrieval logic gets both the name and the address properly. To unit-test the repository, I write an integration test to hit the database. To unit-test the business rules, I mock out the repository, feed the business rules appropriate data, and verify my expected results are returned. What I'd like to do : To unit-test the UI, I mock out the business rules, setup my expected customer instance, render the view, and verify that the view contains the appropriate values for the instance I specified. What I'm stuck doing : To unit-test the repository, I write an integration test, setup an appropriate login, create the required data in the database, open a browser, navigate to the customer, and verify the resulting page contains the appropriate values for the instance I specified. I realize that there is overlap between the two scenarios discussed above, but the key difference it time and effort required to setup and execute the tests. If I (or another dev) removes the address field from the view, I don't want to wait for the integration test to discover this. I want is discovered and flagged in a unit-test that gets multiple times daily. I get the feeling that I'm just not grasping some key concept. Can someone explain why wanting immediate test feedback on the validity of an MVC view is a bad thing? (or if not bad, then not the expected way to get said feedback)

• Creating country specific twitter/facebook accounts

  - by user359650

  I see many companies that have an international presence trying to localize their social media presence by creating country or language specific accounts. However some seemed to have done so without following a consistent pattern, one example being the World Wildlife Fund when you look at their Twitter accounts: World_Wildlife : verified account with 200K followers WWF : main account with 800K followers www_uk : lower case with underscore between WWF and country indicator WWFCanada : upper case with country indicator attached to WWF ... I am planning to build a website which hopefully will grow global and would like to avoid this sort of inconsistencies. Also, I was comparing what Twitter and Facebook allow in their username and found out that they don't allow the same characters to be used (e.g. for instance that the former doesn't allow . whereas the latter does) making difficult to ensure consistency across social networks. Hence my questions: Are there known naming schemes for creating localized Twitter and Facebook accounts while maintaining a certain consistency between them (best effort)? Are there any researches out there that have proven whether some schemes were better than others in terms of readability and/or SEO?

• Would you refactor this and if so, would you charge your client?

  - by Julius

  I am working on a freelance job at home. The client wants me to write some new functionality for his CMS, but it is taking me a lot of time to figure out what the code is doing, because it is written in a very unreadable style. Below is just an example of what I mean. The previous programmer made extensive use of anonymous functions, of eval(), he uses deeply nested ternary operators, he didn't indent code, didn't use comments, and he uses funny constructions like misusing the behaviour of logical operators || and && for creating if/else conditions (the second condition of && only gets tested if the first one is true, opening the possibility to use && as an if/else construction). All in all it's insane code and it's costing me a lot of time to find out how the current code works. return ($this->main->context != "ajax" || in_array($this->type, $this->definition->ajax)) ? eval('return method_exists($this,"Show'.ucfirst($this->type).'") ? $this->Show'.ucfirst($this->type).'('.(count($args) ? join(",",array_map(create_function('$a','return (is_numeric($a) || preg_match("/^array/",$a)) ? $a : "\"".$a."\"";'),$args)) : "").') : null;') : ''; Would you refactor this code and how would you handle this sort of thing with your client, I mean financially?

• How to analyze a scenario where a bug didn't get caught and adjust development workflow to prevent similar errors

  - by durron597

  I had a bug that was really difficult to track down, because all the unit tests were green, but the production application didn't work properly. Here's what happened: I had a filter class that set my application to ignore data that was not in some specified time windows. The unit test, which seemed thorough to me, turned green. Additionally, my integration tests also produced results as expected. Production, however, did not work. As a result of the first two bullets, this problem was very difficult to find. It turned out the problem was that my test dates were using my time zone (America/Chicago) but the production data was providing dates in UTC, which I did not realize, and the logic for the filter wasn't correct for UTC dates. (I was using joda time DateTime objects). Where did my workflow break down? Did I fail to produce a spec that specified that the logic needed to handle dates in any time zone? Did I fail to thoroughly consider all cases at the unit test level? Did I fail to insure the integration test was sufficiently similar to production? Other? What changes can I make to my workflow to better prevent this sort of mistake in the future? How can I more effectively debug a problem when there is an issue in production but not in testing?

• How can create the smallest possible mirror of the archive?

  - by Registered User

  I need to create an http url at my laptop to have a Ubuntu installation begin within my laptop on a Xen environment. This is how the final thing will look like. The host and client are both going to be my laptop, I Googled and came across apt-mirror and some other packages. I do not want to archive entire 15 GB Ubuntu repositories on my machine. It is not possible to use a CD,ISO,loop mounted disk (reason mentioned below). I have tried using netboot image on local machine which failed because if you are attempting to create a virtual machine on a hardware which does not support VT virt-manager installer necessarily needs a URL of this sort http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images/netboot/ Any other option to create guest OS is simply grayed out. The unfortunate part is my Ethernet connections do not work when I boot with Xen-4.0 and a pv-ops Dom0 kernel from Jeremy's tree. Which is where I have to do this work. So I have to create a URL structure which is similar to Ubuntu mirrors. So how can I do this in bare minimum so that at least the console boots and once the console comes I can do some work.

• I've been hired on as a entry-level game developer at a company and have little/no experience in API programming, what should I expect?

  - by Mr. Geneth

  So, I've been hired on as an entry level game developer with little/no experience working with any API other than Win32. This will be an overall learning experience for me as a person and I have gone over this multiple times with the boss and he has no problem with my inexperience. He says that if I'm not worth it now, I will be later. This gives me confidence, but I still feel that I should know a lot more before tackling this position. I would be stupid to pass it up. This is one of my favorite places to come for advice and help and have tried to just accept this, but it just keeps bothering that I can't go in knowing how to at least do the basics. I want to give the company its money's worth. Ya know? My questions are: What should I expect from the other programmers in this project (In terms of patience with me and working together, and being taught)? Is this normal? Any other advice on this sort of thing would be wonderful. I just want to feel comfortable with it.

• Understanding Service Compensation part of Industrial SOA series

  - by JuergenKress

  Some of the most important SOA design patterns that we have successfully applied in projects will be described in this article. These include the Compensation pattern and the UI mediator pattern, the Common Data Format pattern and the Data Access pattern. All of these patterns are included in Thomas Erl's book, "SOA Design Patterns", and are presented here in detail, together with our practical experiences. We begin our "best of" SOA pattern collection with the Compensation pattern. Compensation is required in error situations in an SOA, as multiple atomic service operations cannot generally be linked with classic transactions this would violate the principle of loose coupling. An error situation of this sort will occur, particularly if service operations are combined into processes or new services during orchestration or by applying the Composite pattern, and the transaction bracket has to be expanded as a result. We need mechanisms to undo the effects of individual services (the status changes in the overall system) and to ensure that a consistent system state is maintained at all times, so as to preserve system integrity. For the Compensation pattern, we would like to address the following questions: Why is compensation important in relation to SOA? How is the topic of compensation linked with the topic of transactions? What are the challenges with regard to compensation... Read the full article in the Service Technology Magazine or at OTN.

• Game Resource Generation

  - by Darthg8r

  I am currently building a game that has a "City" entity. These cities generate and consume resources such as food variably over a period of time. I need to be able query the server often to find exactly how much food the city at any given point. These queries can take place multiple times per minute. There could also be 400,000 cities to track at a given time. How would you handle tracking these resources? Would you do it in real time, keeping an instance of the city in memory on the server, with some sort of a snapshot in time of the resources, then computing the growth/consumption from that snapshot time for subsequent queries? Would you work exclusively with a database, using a similar "snapshoting" scheme? Maybe a mixture of the 2, caching recently queried cities in memory for a period of time? There is also a lot of other data that each city needs to track. A player can queue units to build in a barrack. The armies available in the city will need to be updated as units complete. I'm interested in everyone's input on where/when/how you'd manage the real time data.

• .NET Reflector Pro T-shirt contest - and the winner is...

  - by Laila

  Three weeks ago, I kicked off a T-shirt design contest. We've been eagerly poring over the results and today, it's finally announcement time! Although many of you raced to design some great t-shirts for us, we ended up with a clear winner who came up with a nice design and an original slogan that accurately represents what .NET Reflector Pro lets you do: decompile and debug C# and VB.NET code. So, the winner is... Mandeep Sangha! Mandeep sent us the following awesome design via the Twitter account, mss_10: We liked the combination of detective and superhero elements through the magnifying glass and the slogan. Batman (possibly the most eminent of detective-superheroes?) would be proud to wear this under his suit. Mandeep will become the happy owner of a free copy of .NET Reflector Pro and an exciting box of Red Gate goodies... as well as a copy of their very own t-shirt once it's been brought to life by our printing shop! The t-shirts will bear the name of their designer, and will be made available at .NET developer events around the world, such as conferences, tradeshows and user group events. Congratulations, Mandeep! We'll be in touch to sort out the details of your prizes. But that wasn't the only great design we received. We chose three runners-up as well: Sam Beauvois: http://twitpic.com/1vvsi9 Sherwin Rice: http://www.greenwaytechno.com/img/tee-1.png Mathieu Grétry: http://blog.section9.be/public/tshirt_reflector_01.png Thanks to you all for taking part in the contest. You'll all receive a free license for .NET Reflector Pro! We'll get in touch with you individually through twitter, so that we can get you your prizes. Keep an eye out for this T-shirt - it'll soon be making its way to an event near you!

• Adding sub-entities to existing entities. Should it be done in the Entity and Component classes?

  - by Coyote

  I'm in a situation where a player can be given the control of small parts of an entity (i.e. Left missile battery). Therefore I started implementing sub entities as follow. Entities are Objects with 3 arrays: pointers to components pointers to sub entities communication subscribers (temporary implementation) Now when an entity is built it has a few components as you might expect and also I can attach sub entities which are handled with some dedicated code in the Entity and Component classes. I noticed sub entities are sharing data in 3 parts: position: the sub entities are using the parent's position and their own as an offset. scrips: sub entities are draining ammo and energy from the parent. physics: sub entities add weight to the parent I made this to quickly go forward, but as I'm slowly fixing current implementations I wonder if this wasn't a mistake. Is my current implementation something commonly done? Will this implementation put me in a corner? I thought it might be a better thing to create some sort of SubEntityComponent where sub entities are attached and handled. But before changing anything I wanted to seek the community's wisdom.

• Podcast Show Notes: By Any Other Name: Governance and Architecture

  - by Bob Rhubart

  The OTN ArchBeat Podcast returns from a brief summer hiatus with a three-part conversation about IT architecture and governance. My guests for this conversation are Eric Stephens , an Oracle Enterprise architect and a frequent guest on this program. Joining Eric on the panel is Tim Hall , Senior Director of product management for the Oracle Enterprise Repository, Oracle Service Registry, and Oracle Application Integration Architecture. Tim made his first appearance on ArchBeat as panelist on the recent program featuring Thomas Erl. The Conversation Listen to Part 1:Why it's important to revive the dormant conversation about IT governance. Listen to Part 2 (Sept 19): Balancing functional, technical, operational requirements to meet the challenge of defining appropriate governance "guardrails." Listen to Part 3 (Sept 26): Bringing IT architecture out of the ivory tower to make governance a less intimidating, more collaborative process. Additional Resources Leveraging Governance to Sustain Enterprise Architecture Efforts, an Oracle white paper by Eric Stephens. SOA, Cloud, and Service Technologies, a transcript of an ArchBeat interview with Thomas Erl, Tim Hall, and Demed L'Her, in which Tim says the following about governance: "For a long time people have argued that SOA governance is sort of an awkward name, no one wanted to be audited. There's 50% of the world that think, yes, we're going to have to tops down initiative to address this and there's 50% of the world that says that it feels like a heavy weight process that I want no part of. So what I think we should do is change the name…"

• Should I have seperate business and personal websites?

  - by Thomas Clowes

  I have my business website - I am a web designer and developer, and also buy/sell websites/domain names. As such my website links to 'Our sites' = the websites which we design and run as well as a variety of tools such as a domain whois tool. These are obviously relevant to the business. As an individual, I like to travel and do white water kayaking as a hobby. I also have a degree in economics. I have thus created a blog on my business website where I write about domain names, web design, kayaking, travelling and economics. I've just begun researching SEO and am looking into optimizing my business website. I don't actually directly offer any services to clients at the moment, my main aim is to have a business website which supports my websites. If for example a potential advertise on one of my sites checks out the business website, I want them to think professional, down to earth, quirky. Given this is having my business/personal interests intertwined a problem? For SEO.. on my homepage for example when I'm writing a headline and a paragraph about what we do.. what do I put? and how do I optimize for SEO with keywords and the like? Further to the above, my company sponsors me and a group of accquantances as a kayaking team.. as such my personal interests do sort of overlap (just to add a complexity :))

• Should Professional Development occur on company time?

  - by jshu

  As a first-time part-time software developer at a small consulting company, I'm struggling to organise time to further my own software development knowledge - whether that's reading a book, keeping up with the popular questions on StackOverflow, researching a technology we're using in-depth, or following the front page of Hacker News. I can see results borne from my self-allocated study time, but listing and demonstrating the skills and knowledge gained through Professional Development is difficult. The company does not have any defined PD policy, and there's a lot of pressure to get something deliverable done now! when working for consultants. I've checked what my coworkers do, and they don't appear to allocate any time to self-improvement; they just work at the problems they're given, looking up specific MSDN references, code samples, and the like as they need them. I realise that PD policy is going to vary across companies of different size and culture, and a company like my own is probably a bit of an edge case. I'd love to hear views and experiences from more seasoned developers; especially those who have to make the PD policy choices in their team or company. I'd also like to learn about the more radical approaches to PD, even if they're completely out there; it's always interesting to see what other people are trying. Not quite a summary, but what I'm trying to ask: Is it common or recommended for companies to allocate PD time? Whose responsibility is it to ensure a developer's knowledge and skills are up to date? Should a part-time work schedule inspire a lower ratio of PD time : work? How can a developer show non-developer coworkers that reading blogs and books is net productive? Is reading blogs and books actually net productive? (references welcomed) Is writing blogs effective as a way of PD? (a recent theme on Hacker News) This is sort of a broad question because I don't know exactly which questions I need to ask here, so any thoughts on relevant issues I haven't addressed are very welcome.

• Newly installed Ubuntu 12.10 and weird graphics

  - by Benji Marshall

  My machine: 2 GB RAM Intel Pentium Dual core E2180 @ 2 GHz NVIDIA GeForce 6200 LE My friend had recommended Ubuntu to me and I thought I might as well get used to Linux in anticipation for my Raspberry Pi. He said that Wubi was the easiest way to install and I installed it using Wubi. On my first ever boot up of Ubuntu from the Windows Bootloader started normally, and I logged on in a normal fashion, and my desktop loaded normally. I then pressed the Windows key/Power key and everything went wrong. Random lines of yellow and blue appeared on my screen, and changed location when I moved my mouse. The lines stayed for a few seconds and then partially went to I could sort of use my computer. I tried moving my mouse and the entire desktop looked like it broke apart, fragments of it just scatter across my screen at random angles. I could move my mouse and the pointer would move but clicking did nothing. I had to turn off my machine by removing the plug. I would love to get off Windows, but at least the doesn't completely mess up the graphics, and is relatively usable. Please help me solve this....

• Whois status "pending delete" with expiration date in November 2011???

  A friend of mine is in the process of being scammed by a domain registrar and I am trying to sort out the mess. However I could use a hand understanding some of the details. He paid for 2 years of domain name registration on 6 november 2009. The whois record reads: Domain ID:XXXXXXXXXX Domain Name:XXXXXXXXX.ORG Created On:06-Nov-2009 09:23:12 UTC Last Updated On:17-Dec-2010 00:15:10 UTC Expiration Date:06-Nov-2011 09:23:12 UTC Sponsoring Registrar:OnlineNIC Inc. (R64-LROR) Status:CLIENT TRANSFER PROHIBITED Status:HOLD Status:PENDING DELETE SCHEDULED FOR RELEASE Registrant ID:ONLC-XXXXXXX-X Registrant Name:My friend's name ... Registrant Email:Old email The registrar charged a renewal fee a week ago and is now asking an extra $150 to "reclaim" the domain name, even though the domain name is apparently still in my friend's name and it looks like there is still another 10 months before the expiry date. The expiration date on the WhoIs record looks right (Nov 2011), so I don't understand why the domain status says "PENDING DELETE SCHEDULED FOR RELEASE". Can someone explain me better what the deal is and explain what I need to do get the domain name transfered to a more honest registrar? I already have a registrar for my own domain names, been using them for 10 years without problems, so I know where to transfer the domain names to, I just don't know how to proceed.

• My father is a doctor. He is insisting on writing a database to store non-critical patient information, with no programming background

  - by Dominic Bou-Samra

  So, my father is currently in the process of "hacking" together a database using FileMaker Pro, a GUI based databasing tool for his small (4 doctor) practice. The database will be used to help ease the burden on reporting from medical machines, streamlining quite a clumsy process. He's got no programming background, and seems to be doing everything in his power to not learn things correctly. He's got duplicate data types, no database-enforced relationships (foreign/primary key constraints) and a dozen other issues. He's doing it all by hand via GUI tool using Youtube videos. My issue is, that whilst I want him to succeed 100%, I don't think it's appropriate for him to be handling these types of decisions. How do I convince him that without some sort of education in these topics, a hacked together solution is a bad idea? He's can be quite stubborn and I think he sees these types of jobs as "childs play" How should I approach this? Is it even that bad an idea - or am I correct in thinking he should hire a proper DBA/developer to handle this so that it doesn't become a maintenance nightmare? NB: I am a developer consultant of 4 years and I've seen my share of painful customer implementations.

• How do I draw a point sprite using OpenGL ES on Android?

  - by nbolton

  Edit: I'm using the GL enum, which is incorrect since it's not part of OpenGL ES (see my answer). I should have used GL10, GL11 or GL20 instead. Here's a few snippets of what I have so far... void create() { renderer = new ImmediateModeRenderer(); tiles = Gdx.graphics.newTexture( Gdx.files.getFileHandle("res/tiles2.png", FileType.Internal), TextureFilter.MipMap, TextureFilter.Linear, TextureWrap.ClampToEdge, TextureWrap.ClampToEdge); } void render() { Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT); Gdx.gl.glClearColor(0.6f, 0.7f, 0.9f, 1); } void renderSprite() { int handle = tiles.getTextureObjectHandle(); Gdx.gl.glBindTexture(GL.GL_TEXTURE_2D, handle); Gdx.gl.glEnable(GL.GL_POINT_SPRITE); Gdx.gl11.glTexEnvi(GL.GL_POINT_SPRITE, GL.GL_COORD_REPLACE, GL.GL_TRUE); renderer.begin(GL.GL_POINTS); renderer.vertex(pos.x, pos.y, pos.z); renderer.end(); } create() is called once when the program starts, and renderSprites() is called for each sprite (so, pos is unique to each sprite) where the sprites are arranged in a sort-of 3D cube. Unfortunately though, this just renders a few white dots... I suppose that the texture isn't being bound which is why I'm getting white dots. Also, when I draw my sprites on anything other than 0 z-axis, they do not appear -- I read that I need to crease my zfar and znear, but I have no idea how to do this using libgdx (perhaps it's because I'm using ortho projection? What do I use instead?). I know that the texture is usable, since I was able to render it using a SpriteBatch, but I guess I'm not using it properly with OpenGL.

• Are Intel compilers really better than Microsoft ones?

  - by Rocket Surgeon

  Years ago I was surprised when discovered that Intel sells Studio compatible compilers. I tried it in particular for C/C++ as well as fantastic diagnostic tools. But the code was simply not that computationally intensive to notice the difference. The only impression was: did Intel really did it for me just now, Wow, amazing tools with nanoseconds resolution, unbeleivable. But the trial ended and team never seriously considered a purchase. From your experience, if license cost does not matter, which vendor is a winner ? It is not broad or vague question or attemt to spark a holy war. This sort of question about 2 very visible tools. Nobody likes when tools have any mysteries or surprises. And choices between best and best are always the pain. I also understand the "grass greener" argument. I want to hear all "what ifs" stories. What if Intel just locally optimizes it for the chip stepping of the month, and not every hardware target will actually work as well as Microsoft compiled ? What if AMD hardware is the target and everything will slow down for no reason ? Or on other hand, what if Intel's hardware has so many unnoticable opportunities, that Microsoft compiler writers are too slow to adopt and never implement in the compiler ? What if both are the same exactly, actually a single codebase just wrapped into 2 different boxes and licensed to both vendors by some 3rd party shop? And so on. But someone knows some answers.

• A Cautionary Tale About Multi-Source JNDI Configuration

  - by scott.s.nelson(at)oracle.com

  Here's a bit of fun with WebLogic JDBC configurations.  I ran into this issue after reading that p13nDataSource and cgDataSource-NonXA should not be configured as multi-source. There were some issues changing them to use the basic JDBC connection string and when rolling back to the bad configuration the server went "Boom".  Since one purpose behind this blog is to share lessons learned, I just had to post this. If you write your descriptors manually (as opposed to generating them using the WLS console) and put a comma-separated list of JNDI addresses like this: <jdbc-data-source-params> <jndi-name>weblogic.jdbc.jts.commercePool,contentDataSource, contentVersioningDataSource,portalFrameworkPool</jndi-name> <algorithm-type>Load-Balancing</algorithm-type> <data-source-list>portalDataSource-rac0,portalDataSource-rac1</data-source-list> <failover-request-if-busy>false</failover-request-if-busy> </jdbc-data-source-params> so long as the first address resolves, it will still work. Sort of.  If you call this connection to do an update, only one node of the RAC instance is updated. Other wonderful side-effects include the server refusing to start sometimes. The proper way to list the JNDI sources is one per node, like this: <jdbc-data-source-params> <jndi-name>weblogic.jdbc.jts.commercePool</jndi-name> <jndi-name>contentDataSource</jndi-name> <jndi-name>contentVersioningDataSource</jndi-name> <jndi-name>portalFrameworkPool</jndi-name> <algorithm-type>Load-Balancing</algorithm-type> <data-source-list>portalDataSource-rac0, portalDataSource-rac1, portalDataSource-rac2 </data-source-list> <failover-request-if-busy>false</failover-request-if-busy> </jdbc-data-source-params>(Props to Sandeep Seshan for locating the root cause)

• Space-efficient data structures for broad-phase collision detection

  - by Marian Ivanov

  As far as I know, these are three types of data structures that can be used for collision detection broadphase: Unsorted arrays: Check every object againist every object - O(n^2) time; O(log n) space. It's so slow, it's useless if n isn't really small. for (i=1;i<objects;i++){ for(j=0;j<i;j++) narrowPhase(i,j); }; Sorted arrays: Sort the objects, so that you get O(n^(2-1/k)) for k dimensions O(n^1.5) for 2d and O(n^1.67) for 3d and O(n) space. Assuming the space is 2D and sortedArray is sorted so that if the object begins in sortedArray[i] and another object ends at sortedArray[i-1]; they don't collide Heaps of stacks: Divide the objects between a heap of stacks, so that you only have to check the bucket, its children and its parents - O(n log n) time, but O(n^2) space. This is probably the most frequently used approach. Is there a way of having O(n log n) time with less space? When is it more efficient to use sorted arrays over heaps and vice versa?

• Turn-based JRPG battle system architecture resources

  - by BenoitRen

  The past months I've been busy programming a 2D JRPG (Japanese-style RPG) in C++ using the SDL library. The exploration mode is more or less done. Now I'm tackling the battle mode. I have been unable to find any resources about how a classic turn-based JRPG battle system is structured. All I find are discussions about damage formula. I've tried googling, searching gamedev.net's message board, and crawling through C++-related questions here on Stack Exchange. I've also tried reading source code of existing open source RPGs, but without a guide of some sort it's like trying to find a needle in a haystack. I'm not looking for a set of rules like D&D or anything similar. I'm talking purely about code and object structure design. A battle system asks the player for input using menus. Next the battle turn is executed as the heroes and the enemies execute their actions. Can anyone point me in the right direction? Thanks in advance.

• Capitalizing on JavaScript's prototypal inheritance

  - by keithjgrant

  JavaScript has a class-free object system in which objects inherit properties directly from other objects. This is really powerful, but it is unfamiliar to classically trained programmers. If you attempt to apply classical design patterns directly to JavaScript, you will be frustrated. But if you learn to work with JavaScript's prototypal nature, your efforts will be rewarded. ... It is Lisp in C's clothing. -Douglas Crockford What does this mean for a game developer working with canvas and HTML5? I've been looking over this question on useful design patterns in gaming, but prototypal inheritance is very different than classical inheritance, and there are surely differences in the best way to apply some of these common patterns. For example, classical inheritance allows us to create a moveableEntity class, and extend that with any classes that move in our game world (player, monster, bullet, etc.). Sure, you can strongarm JavaScript to work that way, but in doing so, you are kind of fighting against its nature. Is there a better approach to this sort of problem when we have prototypal inheritance at our fingertips?
