• Are there any good html 5 mmo design tutorials? [on hold]

  - by Dwight Spencer

  Hey all. I got a rather inspired after playing gaia online's zOMG and wanted to revive an old project idea I've had laying around for a few years now. I'm looking to work with html5 (ie canvas, svg based sprites, & WebGL) to build a graphical web based MUD/MMO. Obviously, this is a new take on an old idea and after searching google I haven't really turned up many good resources. But does anyone have any tutorials or other resources to point me in the right direction?

• I want to consolidate two sites into a third. Will my search engine rankings be penalized if I rewrite and redirect pages one by one?

  - by Patrick Kenny

  I have two Drupal sites with different content-- let's call them Apple and Orange. I recently developed a much more sophisticated third Drupal site-- let's call it Tree. For a large number of reasons, the content on Apple and Orange is useful for the users of Tree, so I want to move the content to Tree. However, much of the content is out of date. (This whole process took about five years.) To update the content, I will rewrite it one article at a time myself. Now here's my question: if I move the articles one by one (as I rewrite them) and then redirect the old articles (using a 301 redirect) on Apple/Orange to the new site on Tree, will this have a huge negative effect on my search engine rankings? Is there a good way to redirect among sites when they merge like this, or would I be better off keeping the old articles on Apple/Orange and simply linking them to the new, rewritten articles on Tree?

• CCUserDefault, iOS/Android and game updates

  - by Luke

  My game uses cocos2d-x and will be published on iOS platform first, later on Android. I save a lot of things with CCUserDefault (scores, which level was completed, number of coins taken, etc...). But now I have a big doubt. What will happen when the game will receive its first update? CCUserDefault uses an XML file stored somewhere in the app storage space. This file is created and retained until one uninstalls the app. I am wondering what happens when the app is updated. Will the old XML file be maintained? Because if not, how should I handle app updates (updates in the sense that 2, 3 or more new level packages will be added, but the informations about the old ones, like scores, which level was finished and which not, number of coins, etc., need absolutely not to be lost)?

• Problems with EmusicJ on Ubuntu 14.04

  - by Michael Dykes

  I am running Ubuntu 14.04 in my new machine and have a subscription to emusic (because I used it before in my Windows days because of the great selection of classical music). I have used it on my old machine (running older versions of Ubuntu) with some success but am having difficulties doing so now. I am trying to use EmusicJ but do not/cannot remember how to do so. I have downloaded the program and unzipped it and ran the following command in a terminal: ./emusic If I remember correctly, once I go to the emusic site and download my music, the EmucisJ program should open and begin downloading the music through that program but this time it is not and I have already wiped my old box in order to give it to a friend. Any help is appreciated as I would like to continue with Emusic, but if I cannot get this resolved I will likely have to cancel my subscription and find a better alternative. Thanks.

• Video crashes with 10.10

  - by John Mahon

  I have installed both the 64bit and 32 bit versions of 10.10 on my Compaq Presario PC. I first installed the 64 bit version of the OS.The video often crashed when switching user. It also went haywire occasionally when I visited some web-sites. I read that there may be some problems with the 64 bit OS. So I installed the 32 bit version on another disk. This version seemed even less well behaved. HP's model number for the computer is SR1838NX. The hardware is listed at http://bizsupport1.austin.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00628274&lang=en&cc=us&contentType=SupportFAQ&prodSeriesId=1841793&prodTypeId=12454&printver=true#A0 I think the important info is that the chip set is "ATI Radeon Xpress 200" and the processor is "Athlon 64 (S) 3700+ 2.2 GHz" Has anyone else had video problems with similar machines? Is there a work around or an update? I have had previous versions of Ubuntu working on this machine and other flavors of Linux as well. Thanks in advance. John

• New Paper on the PeopleSoft Interaction Hub-PeopleTools Relationship

  - by Matthew Haavisto

  A new paper has just been published that explains the relationships and dependencies between the PeopleSoft Interaction Hub (formerly the PeopleSoft Applications Portal), and PeopleTools.  This paper will help you understand which versions of the Hub work with which versions of Tools.  The paper contains information on how new customers can install the PeopleSoft Interaction Hub, and existing PeopleSoft Interaction Hub customers can apply PIH 9.1 Feature Pack 1 functionality if they are on an earlier version. It also describes how PeopleSoft Interaction Hub releases are aligned with PeopleTools releases, the general upgrade process within the Feature Pack model, and how customers can expect this to work with subsequent feature packs, maintenance packs, and bundles. You can get the paper from Oracle support.

• Java JRE 1.6.0_35 Certified with Oracle E-Business Suite

  - by Steven Chan (Oracle Development)

  The latest Java Runtime Environment 1.6.0_35 (a.k.a. JRE 6u35-b10) is now certified with Oracle E-Business Suite Release 11i and 12 desktop clients.   What's new in Java 1.6.0_35?See the 1.6.0_35 Update Release Notes for details about what has changed in this release.  This release is available for download from the usual Sun channels and through the 'Java Automatic Update' mechanism. 32-bit and 64-bit versions certified This certification includes both the 32-bit and 64-bit JRE versions. 32-bit JREs are certified on: Windows XP Service Pack 3 (SP3) Windows Vista Service Pack 1 (SP1) and Service Pack 2 (SP2) Windows 7 and Windows 7 Service Pack 1 (SP1) 64-bit JREs are certified only on 64-bit versions of Windows 7 and Windows 7 Service Pack 1 (SP1). Worried about the 'mismanaged session cookie' issue? No need to worry -- it's fixed.  To recap: JRE releases 1.6.0_18 through 1.6.0_22 had issues with mismanaging session cookies that affected some users in some circumstances. The fix for those issues was first included in JRE 1.6.0_23. These fixes will carry forward and continue to be fixed in all future JRE releases.  In other words, if you wish to avoid the mismanaged session cookie issue, you should apply any release after JRE 1.6.0_22.All JRE 1.6 releases are certified with EBS upon release Our standard policy is that all E-Business Suite customers can apply all JRE updates to end-user desktops from JRE 1.6.0_03 and later updates on the 1.6 codeline.  We test all new JRE 1.6 releases in parallel with the JRE development process, so all new JRE 1.6 releases are considered certified with the E-Business Suite on the same day that they're released by our Java team.  You do not need to wait for a certification announcement before applying new JRE 1.6 releases to your EBS users' desktops. Important For important guidance about the impact of the JRE Auto Update feature on JRE 1.6 desktops, see: URGENT BULLETIN: All E-Business Suite End-Users Must Manually Apply JRE 6 Updates References Recommended Browsers for Oracle Applications 11i (Metalink Note 285218.1) Upgrading Sun JRE (Native Plug-in) with Oracle Applications 11i for Windows Clients (Metalink Note 290807.1) Recommended Browsers for Oracle Applications 12 (MetaLink Note 389422.1) Upgrading JRE Plugin with Oracle Applications R12 (MetaLink Note 393931.1) Related Articles Mismanaged Session Cookie Issue Fixed for EBS in JRE 1.6.0_23 Roundup: Oracle JInitiator 1.3 Desupported for EBS Customers in July 2009

• Java update alert: issue with EAS 11.1.2.3

  - by inowodwo

  (in via Nancy) Customers using EPM 11.1.2.3 and a web browser to launch the Essbase Administration Services Console will lose the ability to launch EAS Console via the Web URL if they apply Java 1.7 build 45. Development is currently investigating this issue. Workaround: If Java 1.7 Update 45 has been installed, it will need to be uninstalled and a previous version will need to be installed. Older versions of Java are available in the Java Archive Note: Though it may work, Java 1.7 is not supported in previous versions of EAS. Customers running a version of EAS Console prior to 11.1.2.3 need to install the supported version of JRE. Follow this in the Community

• OpenGL behaviour depending on the graphics card?

  - by Dan

  This is something that never happened to me before. I have an OpenGL code that uses GLSL shaders to texture a 3D model. The code involves a lot of GPU texture processing, blending, etc... I wanted to check how the performance of my code improves using a faster graphics card (both new and old are NVIDIA, using always the NVIDIA development drivers). But now I have found that once I run the code using the new graphics card, it behaves completely different (the final render looks wrong), probably because some blending effect is not performed correctly. I haven't really look into what has changed, but I am guessing that some OpenGL states are, by default, set different. Is this possible? Have you ever found different OpenGL/GLSL behaviour using different graphics cards? Any "fast" solution? (So far I've thought of plugging back the old one, push all OpenGL default states, and compare with the ones I initially get using the new card..)

• Examples of "Lost art" on software technology/development

  - by mamcx

  With the advent of a new technology, some old ideas - despite been good - are forgotten in the process. I read a lot how some "new" thing was already present in Lisp like 60 years ago, but only recently resurface with other name or on top of another language. Now look like the new old thing is build functional, non-mutable, non-locking-thread stuff... and that make me wonder what have been "lost" in the art of development of software? What ideas are almost forgotten, waiting for resurface? One of my, I remember when I code in foxpro. The idea of have a full stack to develop database apps without impedance mismatch is something I truly miss. In the current languages, I never find another environment that match how easy was develop in fox back them. What else is missing?

• Dual Boot 10.10 and 11.04 can't boot into 10.10 after an update.

  - by Gaurav Butola

  I've been dual booting my system with Ubuntu 10.10 (Maverick Meerkat) and 11.04 (Natty Narwhal) but today after an update, I can't boot into 10.10, there's only option to boot into 11.04 and Grub also looks a bit different. Before this update, I used to see first option for 11.04 and an other option called /dev/sda1 for 10.10 but now there is a new option called Previous Linux Versions, but when I Enter into that menu, there is no option to boot into 10.10 all the options take me to 11.04 now it looks like this... And when I click on Previous Linux Versions...

• Can't get into the admin console after migrating to new server

  - by Emerson

  I migrated my WordPress blog to a new server, and everything seemed to be working fine until it started giving me the error when entering the admin area: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 4864 bytes) in /home/neworder/public_html/blog/wp-admin/includes/plugin.php on line 729 The line 729 has: $protected = array( '_wp_attached_file', '_wp_attachment_metadata', '_wp_old_slug', '_wp_page_template' ); I had installed the maintenance-mode, and I have suspicions that this is what broke the forum. If I remove the plugin it then gives another error: Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 19456 bytes) in /home/neworder/public_html/blog/wp-admin/includes/post.php on line 1158 And that line has: $content .= '<p class="hide-if-no-js">' . esc_html__( 'Remove featured image' ) . '</p>'; } I tried to restore the blog file-system from the old server and also to restore the database from the old server (2x), but still it gives me the same error. The blog itself seems to be working fine: http://blog.antinovaordemmundial.com/

• How to design a separated tutorial mode?

  - by Sylpheed

  I'm working on a "social" game that's about 90% completion. One of the remaining features is the tutorial mode. Basically, the tutorial mode will restrict the user to access some parts of UI and limit the features (like store items). The tutorial will only progress if a certain event is triggered, specifically following the tutorial. The code is ready and we already have an "almost" working game. The problem is I haven't foreseen the tutorial mode while I was doing those 90%. My requirement is there shouldn't be any loading/transition from tutorial mode to normal mode. This means I have to pick up the progress from the tutorial (no re-rendering of assets and stuff). How should I design this in a way where I won't touch anything from my old code? I want it to be as easy as just plugging it in. I don't want to jam the tutorial in my old code since this will lead to many bugs.

• Wrong statistics in AUX_STATS$ might puzzle the optimizer

  - by Mike Dietrich

  We do recommend the creation of System Statistics for quite a long time. Since Oracle 9i the optimizer works with a CPU and IO cost based model. And in order to give the optimizer some knowledge about the IO subsystem's performance and throughput - once System Statistics are collected - they'll get stored in AUX_STATS$. For this purpose in the old Oracle 9i days some default values had been defined - and you'll still find those defaults in Oracle Database 11g Release 2 in AUX_STATS$. But these old values don't reflect the performance of modern IO systems. So it might be a good best practice post upgrade to create fresh System Statistics if you haven't done this before.  You can collect System Statistics with: exec DBMS_STATS.GATHER_SYSTEM_STATS('start'); and end it later by executing: exec DBMS_STATS.GATHER_SYSTEM_STATS('stop'); You could also run DBMS_STATS.GATHER_SYSTEM_STATS('interval', interval=>N) instead where N is the number of minutes when statistics gathering is stopped automatically. Please make sure you'll do this on a real workload period. It won't make sense to gather these values while the database is in an idle state. You should do this ideally for several hours. It doesn't affect performance in a negative way as the values are anyway collected in V$SYSSTAT and V$SESSTAT. And in case you'd like to delete the stats and revert to the old default values you'd simply execute:exec DBMS_STATS.DELETE_SYSTEM_STATS; The tricky thing in Oracle Database 11.2 - and that's why I'm actually writing this blog post today - is bug9842771. This leads to wrong values in AUX_STATS$ for SREADTIM and MREADTIM by factor 1000 guiding the optimizer sometimes into the totally wrong directon. The workaround is to overwrite these values manually and divide them by 1000. Use the DBMS_STATS.SET_SYSTEM_STATS procedure. See this MOS Note:9842771.8 for the above bug for some further information. This issue is fixed in Oracle Database 11.2.0.3 and above. To get some background information about the statistics collected in please read this section in the Oracle Database 11.2 Performance Tuning Guide. And gathering System Statistics might have some implication if you have mixed workloads - and interacts with DB_FILE_MULTIBLOCK_READ_COUNT. For more information please read section 13.4.1.2.

• Optical Character Recognition software recommendations?

  - by Tim

  I have seen some ebooks/papers that were apparently scanned from their paper versions but the text in the ebooks/papers can amazingly be copied out. I suppose the directly-scanned versions must have been processed by some Optical Character Recognition software. So I would like to know what are the recommended Optical Character Recognition softwares? Especially those that are either for Ubuntu or free? If those for Windows are far more superior, please let me know as well. I am particularly interested in those OCRs that can accept a scanned pdf file as input and still produce as output another pdf file that looks the same as the input one but with its text copyable. Thanks and regards! Please limit one software per answer

• eDelivery (Delivery Cloud) Housekeeping - removal of obsolete EPM products

  - by THE

  You may have noticed that Weblogic Server (WLS) 9.2.X and WLS 10.0.X releases have been removed from the Oracle Software Delivery Cloud. The Delivery Team has been asked to remove or update any product pack or product that embeds WLS 10.3.2 or earlier versions. This is consistent with general Oracle practice of removing old product versions from public distribution systems, and encourages customer usage and adoption of newer product releases such as WLS 10.3.3 or newer.  For the convenience of existing supported customers, a media request SR on My Oracle Support can be entered to obtain any removed media.  Information on how to open such an SR can be found on  MOS Doc ID 1071023.1 . OTN will also be reviewed and similar modifications may potentially be done.  The following media packs will be removed from E-Delivery this week, as of the above reason. Hyperion 9.3.1 Hyperion 9.2.1 Hyperion Pre-system 9 EPM 11.1.1.3 EPM 11.1.1.4

• Dev Lop

  - by Jason Franks

  Back in the early 90s, before I was a professional geek--much less a geek with a blog--I saw this old chop socky movie. I don't remember what it was called, or who was in it... all I remember is that, in one scene, the venerable sensei tells the hero: "You must develop your nunchaku technique." This became a bit fo a catchphrase amongst my high school mates. Well folks, I am developing my technuique. This blog has been renamed and the old posts removed--I could go into my reasons for this, but that would defeat the point of the exercise. Sorry if you liked 'em. It has been a good couple of years since I wrote anything here, so I doubt that I am putting out any regular readers. Will I be posting here more often, now that I've renamed and rethemed the place? I don't know. In the meantime, check it out: Bruce Lee playign ping pong with nunchaku. --JF

• How can I get started programming OpenGL on Mac OS X?

  - by Michael Stum

  I'm trying to start OpenGL programming on a Mac, which brings me into unknown territory on a lot of things. During the day, I'm a Web Developer, working in C# and before that in PHP and Delphi, all on Windows. During the night, I try to pick up Mac/OpenGL skills, but everything is so different. I've been trying to look for some books, but the OpenGL books are usually for iOS (tons of them out there) and the Mac Books usually cover "normal" application Development. I want to start simple with Pong, Tetris and Wolfenstein. I see that there are a bunch of different OpenGL Versions out there. I know about OpenGL ES 1&2, but I don't know about the "big" OpenGL Versions - which ones are commonly supported on 10.6 and 10.7 on current (2010/2011) Macs? Are there any up to date (XCode 4) books or tutorials? I don't want to use a premade Engine like Unity yet - again, I know next to nothing about any Mac development.

• Google Webmaster Tools shows invalid data

  - by Altar

  Webmaster Tools shows 1 URL error (not found page). The report says that 5 pages are linking to a page (let's call it x) that does not exist (and because it doesn't exists it returns a soft 404). HOWEVER, I look in those 5 pages (in the source code) and none is linking to the x page. It is like Google sees an old page that was indeed pointing to x. What is the problem? How do I know if Google cached an old version for those 5 pages?
