• Real-Time Strategy Gameplay

  - by Ahmad Alkhawaja

  I am working on building a HTML5 RTS game, and my current state is that I am building the Campaign mode of the game, and want to define the gameplay (The Scoring, Unit Behaviors/Attributes). I am searching for links/articles/books about how to define the gameplay, for me this: The scoring Figuring out levels of control (in any RTS game, there is units, individuals and squads) Unit action/attributes/properties point timing (how long it will take to play?) Achievements ..etc I want to see how they usually define these areas in RTS games, I expect to see general document discussing this concept that I can use to build the gameplay. Any idea? Is my question clear or I need to provide more details?

• Differences between Dynamic Dispatch and Dynamic Binding

  - by Prog

  I've been looking on Google for a clear diffrentiation with examples but couldn't find any. I'm trying to understand the differences between Dynamic Dispatch and Dynamic Binding in Object Oriented languages. As far as I understand, Dynamic Dispatch is what happens when the concrete method invoked is decided at runtime, based on the concrete type. For example: public void doStuff(SuperType object){ object.act(); } SuperType has several subclasses. The concrete class of the object will only be known at runtime, and so the concrete act() implementation invoked will be decided at runtime. However, I'm not sure what Dynamic Binding means, and how it differs from Dynamic Dispatch. Please explain Dynamic Binding and how it's different from Dynamic Dispatch. Java examples would be welcome.

• Advice on SCRUM for the solitary developer [closed]

  - by ProfK

  Possible Duplicate: Agile for the Solo Developer I am looking for advice on the SCRUM process for a solitary developer. Most SCRUM resources I see focus on its use in a team environment, hence my question here. I'd like some guidance on structuring and managing my projects for SCRUM, with me as a solitary developer and business owner, but still occasionally including my clients for input and feedback. Areas I'm not clear on include resolving my backlog into 'sprintable' project areas and stories, defining user stories properly with a view to being digested by developer level users, defining feasible sprints for a single developer etc. Essentially I'm looking for advice on moving from using scrum in a team/office environment, with colleagues and project manager, and using chaos/cowboy-coding on my own, to assuming the role of PM myself and adopting scrum for work on my own. Any advice is welcome.

• What are the leading professional journals in software development?

  - by Austin Hyde

  In one of my classes, we were asked to research the top professional journals in our field. According to what I can dig up, the ACM and IEEE journals are the "best", as they come up at the top of my searches and this question. However, there are a dozen or so individually topic-ed journals for each, with no very clear measure of which one is most useful, popular, etc. For example, "IEEE Software" vs. "IEEE Transactions on Software Engineering". So, what do you consider to be the "leading" professional journals (specifically), and why? It doesn't have to be only ACM or IEEE, either. If you know of another, please add it.

• Mount drives at `/drivename` from nautilus

  - by Anwar Shah

  I want to mount my other drives (mostly ntfs and fat) on /drivename by clicking on the drive icon in the nautilus side pane, where "drivename" refers to the label of the drive. By default nautilus (actually the udisks program) mounts drives in /media/ folder with drive name. How can I achieve this?. Note: Please do not suggest doing this by editing /etc/fstab file. I want this feature in nautilus and after clicking the drive should also be seen in the side pane. (should not be hidden). Edit: Seems to be some have misunderstood this. I don't want to mount in / but as /Main, where "Main" is the label of my ntfs partition. To make it clear, suppose I have two partitions named as "Work" and "Main". I want them to mount at /Work and /Main respectively, when clicked on their icon in nautilus

• Generalize, or Fix The Problem?

  - by Droogans

  Which of these two programmers is "better", from a managerial standpoint? The first programmer is Albert. You tell Al to make a system that will pass you the salt at the dinner table. He does it in less than a day. It works fine. The second programmer is Ben. Ben is told to make a program to pass the salt, and after two days, he's still working on it. It will save time in the long run...if you need pepper, ketchup, etc. There isn't any clear indication that there will be a need for this, but it's not improbable. Who's the better programmer to have working under you, as a manager?

• View Docs and PDFs Directly in Google Chrome

  - by Matthew Guay

  Would you like to view documents, presentations, and PDFs directly in Google Chrome?  Here’s a handy extension that makes Google Docs your default online viewer so don’t have to download the file first. Getting Started By default, when you come across a PDF or other common document file online in Google Chrome, you’ll have to download the file and open it in a separate application. It’d be much easier to simply view online documents directly in Chrome.  To do this, head over to the Docs PDF/PowerPoint Viewer page on the Chrome Extensions site (link below), and click Install to add it to your browser. Click Install to confirm that you want to install this extension. Extensions don’t run by default in Incognito mode, so if you’d like to always view documents directly in Chrome, open the Extensions page and check Allow this extension to run in incognito. Now, when you click a link for a document online, such as a .docx file from Word, it will open in the Google Docs viewer. These documents usually render in their original full-quality.  You can zoom in and out to see exactly what you want, or search within the document.  Or, if it doesn’t look correct, you can click the Download link in the top left to save the original document to your computer and open it in Office.   Even complex PDF render very nicely.  Do note that Docs will keep downloading the document as you’re reading it, so if you jump to the middle of a document it may look blurry at first but will quickly clear up. You can even view famous presentations online without opening them in PowerPoint.  Note that this will only display the slides themselves, but if you’re looking for information you likely don’t need the slideshow effects anyway.   Adobe Reader Conflicts If you already have Adobe Acrobat or Adobe Reader installed on your computer, PDF files may open with the Adobe plugin.  If you’d prefer to read your PDFs with the Docs PDF Viewer, then you need to disable the Adobe plugin.  Enter the following in your Address Bar to open your Chrome Plugins page: chrome://plugins/ and then click Disable underneath the Adobe Acrobat plugin. Now your PDFs will always open with the Docs viewer instead. Performance Who hasn’t been frustrated by clicking a link to a PDF file, only to have your browser pause for several minutes while Adobe Reader struggles to download and display the file?  Google Chrome’s default behavior of simply downloading the files and letting you open them is hardly more helpful.  This extension takes away both of these problems, since it renders the documents on Google’s servers.  Most documents opened fairly quickly in our tests, and we were able to read large PDFs only seconds after clicking their link.  Also, the Google Docs viewer rendered the documents much better than the HTML version in Google’s cache. Google Docs did seem to have problem on some files, and we saw error messages on several documents we tried to open.  If you encounter this, click the Download link in the top left corner to download the file and view it from your desktop instead. Conclusion Google Docs has improved over the years, and now it offers fairly good rendering even on more complex documents.  This extension can make your browsing easier, and help documents and PDFs feel more like part of the Internet.  And, since the documents are rendered on Google’s servers, it’s often faster to preview large files than to download them to your computer.

• keybinding issues with xmodmap across synergy

  - by Rick

  I've got two systems I use across Synergy. On the main one I have a normal keyboard that I swap caps lock and ctrl for. So I do: xmodmap -e 'keycode 66 = Control_L' xmodmap -e 'clear lock' xmodmap -e 'add Control = Control_L' Where keycode 66 is my caps lock key. The trouble is that I can't get this key to act as a control key on the other machine I connect to with synergy. The strange thing is that if I plug a keyboard into the machine, and run xev, the control key there is keycode 37. When I then hit my modified control key (keycode 66 on the master) it's registering as keycode 37 on the remote machine. So according to xev, it should be picking it up as a control keypress. Anyone have any hints on if Synergy is doing something overly helpful for me?

• Talend Enterprise Data Integration overperforms on Oracle SPARC T4

  - by Amir Javanshir

  The SPARC T microprocessor, released in 2005 by Sun Microsystems, and now continued at Oracle, has a good track record in parallel execution and multi-threaded performance. However it was less suited for pure single-threaded workloads. The new SPARC T4 processor is now filling that gap by offering a 5x better single-thread performance over previous generations. Following our long-term relationship with Talend, a fast growing ISV positioned by Gartner in the “Visionaries” quadrant of the “Magic Quadrant for Data Integration Tools”, we decided to test some of their integration components with the T4 chip, more precisely on a T4-1 system, in order to verify first hand if this new processor stands up to its promises. Several tests were performed, mainly focused on: Single-thread performance of the new SPARC T4 processor compared to an older SPARC T2+ processor Overall throughput of the SPARC T4-1 server using multiple threads The tests consisted in reading large amounts of data --ten's of gigabytes--, processing and writing them back to a file or an Oracle 11gR2 database table. They are CPU, memory and IO bound tests. Given the main focus of this project --CPU performance--, bottlenecks were removed as much as possible on the memory and IO sub-systems. When possible, the data to process was put into the ZFS filesystem cache, for instance. Also, two external storage devices were directly attached to the servers under test, each one divided in two ZFS pools for read and write operations. Multi-thread: Testing throughput on the Oracle T4-1 The tests were performed with different number of simultaneous threads (1, 2, 4, 8, 12, 16, 32, 48 and 64) and using different storage devices: Flash, Fibre Channel storage, two stripped internal disks and one single internal disk. All storage devices used ZFS as filesystem and volume management. Each thread read a dedicated 1GB-large file containing 12.5M lines with the following structure: customerID;FirstName;LastName;StreetAddress;City;State;Zip;Cust_Status;Since_DT;Status_DT 1;Ronald;Reagan;South Highway;Santa Fe;Montana;98756;A;04-06-2006;09-08-2008 2;Theodore;Roosevelt;Timberlane Drive;Columbus;Louisiana;75677;A;10-05-2009;27-05-2008 3;Andrew;Madison;S Rustle St;Santa Fe;Arkansas;75677;A;29-04-2005;09-02-2008 4;Dwight;Adams;South Roosevelt Drive;Baton Rouge;Vermont;75677;A;15-02-2004;26-01-2007 […] The following graphs present the results of our tests: Unsurprisingly up to 16 threads, all files fit in the ZFS cache a.k.a L2ARC : once the cache is hot there is no performance difference depending on the underlying storage. From 16 threads upwards however, it is clear that IO becomes a bottleneck, having a good IO subsystem is thus key. Single-disk performance collapses whereas the Sun F5100 and ST6180 arrays allow the T4-1 to scale quite seamlessly. From 32 to 64 threads, the performance is almost constant with just a slow decline. For the database load tests, only the best IO configuration --using external storage devices-- were used, hosting the Oracle table spaces and redo log files. Using the Sun Storage F5100 array allows the T4-1 server to scale up to 48 parallel JVM processes before saturating the CPU. The final result is a staggering 646K lines per second insertion in an Oracle table using 48 parallel threads. Single-thread: Testing the single thread performance Seven different tests were performed on both servers. Given the fact that only one thread, thus one file was read, no IO bottleneck was involved, all data being served from the ZFS cache. Read File ? Filter ? Write File: Read file, filter data, write the filtered data in a new file. The filter is set on the “Status” column: only lines with status set to “A” are selected. This limits each output file to about 500 MB. Read File ? Load Database Table: Read file, insert into a single Oracle table. Average: Read file, compute the average of a numeric column, write the result in a new file. Division & Square Root: Read file, perform a division and square root on a numeric column, write the result data in a new file. Oracle DB Dump: Dump the content of an Oracle table (12.5M rows) into a CSV file. Transform: Read file, transform, write the result data in a new file. The transformations applied are: set the address column to upper case and add an extra column at the end, which is the concatenation of two columns. Sort: Read file, sort a numeric and alpha numeric column, write the result data in a new file. The following table and graph present the final results of the tests: Throughput unit is thousand lines per second processed (K lines/second). Improvement is the % of improvement between the T5140 and T4-1. Test T4-1 (Time s.) T5140 (Time s.) Improvement T4-1 (Throughput) T5140 (Throughput) Read/Filter/Write 125 806 645% 100 16 Read/Load Database 195 1111 570% 64 11 Average 96 557 580% 130 22 Division & Square Root 161 1054 655% 78 12 Oracle DB Dump 164 945 576% 76 13 Transform 159 1124 707% 79 11 Sort 251 1336 532% 50 9 The improvement of single-thread performance is quite dramatic: depending on the tests, the T4 is between 5.4 to 7 times faster than the T2+. It seems clear that the SPARC T4 processor has gone a long way filling the gap in single-thread performance, without sacrifying the multi-threaded capability as it still shows a very impressive scaling on heavy-duty multi-threaded jobs. Finally, as always at Oracle ISV Engineering, we are happy to help our ISV partners test their own applications on our platforms, so don't hesitate to contact us and let's see what the SPARC T4-based systems can do for your application! "As describe in this benchmark, Talend Enterprise Data Integration has overperformed on T4. I was generally happy to see that the T4 gave scaling opportunities for many scenarios like complex aggregations. Row by row insertion in Oracle DB is faster with more than 650,000 rows per seconds without using any bulk Oracle capabilities !" Cedric Carbone, Talend CTO.

• component Initialization in component-based game architectures

  - by liortal

  I'm develping a 2d game (in XNA) and i've gone slightly towards a component-based approach, where i have a main game object (container) that holds different components. When implementing the needed functionality as components, i'm now faced with an issue -- who should initialize components? Are components usually passed in initialized into an entity, or some other entity initialized them? In my current design, i have an issue where the component, when created, requires knowledge regarding an attached entity, however these 2 events may not happen at the same time (component construction, attaching to a game entity). I am looking for a standard approach or examples of implementations that work, that overcome this issue or present a clear way to resolve it

• Database vs Networking

  - by user16258

  I have completed my diploma in (IT) and now pursuing degree, i am in last semester of my B.E(I.T). I want to do specialization either in Database(oracle) or in Networking(cisco). Which one of two will be in more demand in near future, i know it's all about interest but still i would like to know your opinion. Most of people say that a network engineer is never paid as better as a programmer or a DBA, and few says they do get paid well. What would be the scope if i clear my CCNA and CCNP exams, or either OCA & OCP exams, what would be more rewarding. Also i have read somewhere that most of the task of DBA will be automated so in future demand of a DBA will reduce. I would also like to hear from Network engineers what's the scenario out there in India. Thanks

• Strategy to find bottleneck in a network

  - by Simone

  Our enterprise is having some problem when the number of incoming request goes beyond a certain amount. To make things simpler, we have N websites that uses, amongst other, a local web service. This service is hosted by IIS, and it's a .NET 4.0 (C#) application executed in a farm. It's REST-oriented, built around OpenRasta. As already mentioned, by stress testing it with JMeter, we've found that beyond a certain amount of request the service's performance drop. Anyway, this service is, amongst other, a client itself of other 3 distinct web services and also a client for a DB server, so it's not very clear what really is the culprit of this abrupt decay. In turn, these 3 other web services are installed in our farm too, and client of other DB servers (and services, possibly, that are out of my team control). What strategy do you suggest to try to locate where the bottleneck(s) are? Do you have any high-level suggestions?

• Understanding Ajax crawling of search site

  - by vacuum

  I have a couple of questions about Ajax crawling of site, which is kind of search engine itself. The base article explains the mechanism of making AJAX application crawlable. All this stuff with HTML-snapshots is clear and easy to implement, but I cant understand where will Google bot will get "the crawler finds a pretty AJAX URL"( ie www.example.com/ajax.html#key=value) to work with. First thing, that came on mind - is breadcrumb. In sitemap we can specify pages with breadcrumb on it. so bot will go to these pages and get HTML-snapshots from here. But I'm sure, there are exists other ways to give bot this "pretty AJAX URL". In our case, we have simple search site, where user enters keyword, presses "Find", js execute Ajax request, receives JSON reponce and fill page with results(without any refresh of course). In this case - how to make google bot crawle all the presults in addition to sitemap? Is there some example of solution, described in article above?

• Pay Per Click Software

  - by Eddy Freeman

  What software do sites like www.shopzilla.com, www.become.com, www.kelkoo.com etc.. use for the Pay-Per-Click product listing campaigns they offer for their retailers. I am asking what kind of software do they use to know that a certain retailer's products has been clicked 50 times or 100 times(and then the cost of the click is deducted from his money-account) etc... Can someone point me to those kind of softwares? EDIT *Some Explanation :: * In a site like www.shopzilla.com, retailers will upload thier products(list their products on the site). Anytime a buyer clicks on a product to go the retailer's website, an amount of money(say $0.20) is deducted from his account(the money he has deposited in his account with shopzilla). A retailer can see how many times buyers have clicked on his products and how much money remains in his shopzilla accounts. Am looking for such softwares that comparison sites like shopzilla uses to run this type of campaigns. I hope it is clear now.

• Modified Strategy Design Pattern

  - by Samuel Walker

  I've started looking into Design Patterns recently, and one thing I'm coding would suit the Strategy pattern perfectly, except for one small difference. Essentially, some (but not all) of my algorithms, need an extra parameter or two passed to them. So I'll either need to pass them an extra parameter when I invoke their calculate method or store them as variables inside the ConcreteAlgorithm class, and be able to update them before I call the algorithm. Is there a design pattern for this need / How could I implement this while sticking to the Strategy Pattern? I've considered passing the client object to all the algorithms, and storing the variables in there, then using that only when the particular algorithm needs it. However, I think this is both unwieldy, and defeats the point of the strategy pattern. Just to be clear I'm implementing in Java, and so don't have the luxury of optional parameters (which would solve this nicely).

  - by ultan o'broin

  Picked this up from a recent Dublin Google Technology User Group meeting: Android App Mistakes: Avoiding the Anti-Patterns by Mark Murphy, CommonsWare Interesting approach of "anti-patterns" aimed at mobile developers (in this case Android), looking at the best way to use code and what's in the SDK while combining it with UX guidance (the premise being the developer does the lot). Interestingly, the idea came through that developers need to stop trying to make one O/S behave like another--on UX grounds. Also, pretty clear that a web-based paradigm is being promoting for Android (translators tell me that translating an Android app reminded them of translating web pages too). Haven't see the "anti"-approach before, developer cookbooks and design patterns sure. Check out the slideshare presentation.

• How to control in the vertex shader where pixel ends up in the renderTarget?

  - by cubrman

  What if I have an arbitrary renderTarget, that is smaller than the screen (say it is 1x1 pixel) and I want to make sure in the VertexShaderFunction that all my pixels end up exactly in that 1 pixel region? No matter what I do, they all seem to get culled at some point, though GraphicDevise.Clear() works OK. Where is the top left corner of the renderTarget Vertex-shader-vise? I tried output.Position = (0,0,0,0)/(0,0,0,1)/(1,1,1,1)/(-0.5,0.5,0,1) NOTHING works! Fullscreen quad is not an option 'cause I actually need to process geometry in the shaders to get the results I need.

• YouTube: Tips by Bitwise Courses on NetBeans

  - by Geertjan

  I really like the potential of YouTube in providing a platform for short info clips that take not much time to produce and about as much time to consume. Huw Collingbourne's Bitwise Courses channel is full of exactly this kind of YouTube clip. Several of his YouTube clips are about or make use of NetBeans. The related Twitter account is @bitwisecourses and the homepage is bitwisecourses.com. Here's a great example, the latest YouTube clip created by Bitwise Courses. Very clear and simple explanation, on a specific and narrow topic, and very short and sweet. And very useful! Didn't know about this feature myself. Direct link to the movie: https://www.youtube.com/watch?v=b0fKT_hFQpU Here's to more of these, they're wonderful. More such YouTube clips are needed, short and precise, on very specific topics. And I'm very happy to promote them, as you can see.
