• Good, free isometric game engine?

  - by posfan12

  Any recommendations for a good isometric game engine that is also free? Should be possible to develop entirely using freely available tools (meaning: no Flash, and no I don't want to learn haXe...) Works-in-a-browser is a plus, but not required. Support for 32-bit images is required! Good performance. Excellent documentation. I have looked at FIFE but it is still too unfinished, and the documentation sucks! Thanks!

• Oracle Service Bus duplicate message check using Coherence by Jan van Zoggel

  - by JuergenKress

  In a situation where you need some sort of duplicate message check for an Oracle Service Bus project you would need some custom code. Since the Oracle Service Bus is stateless, when it handles a proxy service call it will not know if this specific message was handled before. So there needs to be some sort of logic in your service for validating it’s a new unique message id. Read the full article here.

• Shader effect similar to Metro 2033 gasmask

  - by Tim

  I was thinking about effects in games the other day and I was reminded of the Gasmask effect from Metro 2033. Once you put the gasmask on it blurred a bit in the corners and could ice up and even get cracked. I assume that something like that is done using a shader. I have been experimenting a bit with game development, so far mostly playing with existing rendering engines and adding physics support etc. I would like to learn more about this sort of effect. Can someone give me a simple example of a shader that would alter the entire scene like this. Or if not a shader then an idea on how it would be done. Thanks. Edit : Include screenshot of the metro 2033 gasmask effect.

• Powershell STA watin

  - by Mike Koerner

  Wow, two posts on the same day. I was working on a quick DLL project to do some web scripting using the awsome power of Watin.  In the past I use to create a vbscript as the test handler to call the DLL but lately I got a Powershell bug to call .NET DLLs. When I tried to debug the Watin call I received: The CurrentThread needs to have it's ApartmentState set to ApartmentState.STA to be able to automate Internet Explorer. I couldn't find a quick google answer to powershell apartmentstate .  Apparently you can set the powershell apartment state by the command line -STA.  http://technet.microsoft.com/en-us/library/dd315276.aspx I've found that the powershell documentation and examples is lacking compared to the Microsoft support I've come to expect.  Why is the Powershell v2.0 in C:\WINDOWS\SYSTEM32\windowspowershell\v1.0 ?

• JavaScript Intellisense Improvements with VS 2010

  This is the twentieth in a series of blog posts Im doing on the upcoming VS 2010 and .NET 4 release.  Todays blog post covers some of the nice improvements coming with JavaScript intellisense with VS 2010 and the free Visual Web Developer 2010 Express.  Youll find with VS 2010 that JavaScript Intellisense loads much faster for large script files and with large libraries, and that it now provides statement completion support for more advanced scenarios compared to previous versions...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  - by Vibhore Tanwer

  I am new to DirectX, and trying to learn best practice. Please suggest what are the best practices for rendering on multiple monitors different things at the same time? how can I boost performance of application? I have gone through this article http://msdn.microsoft.com/en-us/library/windows/desktop/bb147263%28v=vs.85%29.aspx . I am making use of some pixel shaders to achieve some effects. At most 4 effect(4 shader effects) can be applied at same time. What are the best practices to achieve best performance with DirectX 9.0. I read somewhere that DirectX 11 provides support for parallel rendering, but I am not able to get any working sample for DirectX 11.0. Please help me with this, Any help would be of great value.

• Often "running in low-graphics mode” with NVidia GeForce GT 430

  - by user42228

  Often (every fifth time perhaps) when I turn on my system, I'm greeted with the "running in low-graphics mode” window. Sometimes all I have to do is reboot and the system will start correctly, sometimes there can be a longer series of failed starts. If I go to the terminal and log in, I can run startx and my desktop will appear without problems. At the end of /var/log/Xorg.1.log I see this: [ 77.459] (EE) Screen(s) found, but none have a usable configuration. [ 77.459] Fatal server error: [ 77.459] no screens found [ 77.459] Please consult the The X.Org Foundation support at http://wiki.x.org Is the NVidia creating the appropriate XOrg configuration dynamically on every boot, or what could explain that the configuration error above only occurs sometimes?

• Oracle Unbreakable Enterprise Kernel and Emulex HBA Eliminate Silent Data Corruption

  - by sergio.leunissen

  Yesterday, Emulex announced that it has added support for T10 Protection Information (T10-PI), formerly called T10-DIF, to a number of its HBAs. When used with Oracle's Unbreakable Enterprise Kernel, this will prevent silent data corruption and help ensure the integrity and regulatory compliance of user data as it is transferred from the application to the SAN From the press release: Traditionally, protecting the integrity of customers' data has been done with multiple discrete solutions, including Error Correcting Code (ECC) and Cyclic Redundancy Check (CRC), but there have been coverage gaps across the I/O path from the operating system to the storage. The implementation of the T10-PI standard via Emulex's BlockGuard feature, in conjunction with other industry player's implementations, ensures that data is validated as it moves through the data path, from the application, to the HBA, to storage, enabling seamless end-to-end integrity. Read the white paper and don't miss the live webcast on eliminating silent data corruption on December 16th!

• Any Good Cocos2d Pause Menu Library

  - by Mahbubur R Aaman

  Background : From http://code.google.com/p/cocos2d-iphone/issues/detail?id=173 Scenes/Nodes doesn't support the CocosNodeOpacity protocol. From http://playsnackgames.com/blog/2011/09/cocos2d-tutorial-creating-a-reusable-pause-layer/ Cocos2d offers a simple method to pause and resume itself, but these methods stop the CCDirector (the class that manages most aspects of a Cocos2d’s app lifetime) from running actions and lower the fps to 5 to conserve battery life.

• Why are there so many spaces and line breaks in Unicode?

  - by maaartinus

  Unicode has maybe 50 spaces \u0009\u000A-\u000D\u0020\u0085\u00A0\u1680\u180E\u2000-\u200A\u2028\u2029\u202F\u205F\u3000][\u0009\u000A-\u000D\u0020\u0085\u00A0\u1680\u180E\u2000-\u200A\u2028\u2029\u202F\u205F\u3000 and 6 line breaks not only CRLF, LF, CR, but also NEL (U+0085), PS (U+2029) and LS (U+2028). Maybe I could understand most of the spaces and PS ("Paragraph separator"), but what are "Next Line" and "Line separator" good for? It all looks like invented by a very big committee where everybody wanted their own space and the leaders were granted one line break each. But seriously, how do you deal with it when your programming language doesn't support it (or does it wrong as e.g. Java does)?

• How to export ECC key and Cert from NSS DB and import into JKS keystore and Oracle Wallet

  - by mv

  How to export ECC key and Cert from NSS DB and import into JKS keystore and Oracle Wallet In this blog I will write about how to extract a cert and key from NSS Db and import it to a JKS Keystore and then import that JKS Keystore into Oracle Wallet. 1. Set Java Home I pointed it to JRE 1.6.0_22 $ export JAVA_HOME=/usr/java/jre1.6.0_22/ 2. Create a self signed ECC cert in NSS DB I created NSS DB with self signed ECC certificate. If you already have NSS Db with ECC cert (and key) skip this step. $export NSS_DIR=/export/home/nss/ $$NSS_DIR/certutil -N -d . $$NSS_DIR/certutil -S -x -s "CN=test,C=US" -t "C,C,C" -n ecc-cert -k ec -q nistp192 -d . 3. Export ECC cert and key using pk12util Use NSS tool pk12util to export this cert and key into a p12 file      $$NSS_DIR/pk12util -o ecc-cert.p12 -n ecc-cert -d . -W password 4. Use keytool to create JKS keystore and import this p12 file 4.1 Import p12 file created above into a JKS keystore $JAVA_HOME/bin/keytool -importkeystore -srckeystore ecc-cert.p12 -srcstoretype PKCS12 -deststoretype JKS -destkeystore ecc.jks -srcstorepass password -deststorepass password -srcalias ecc-cert -destalias ecc-cert -srckeypass password -destkeypass password -v But if an error as shown is encountered, keytool error: java.security.UnrecoverableKeyException: Get Key failed: EC KeyFactory not available java.security.UnrecoverableKeyException: Get Key failed: EC KeyFactory not available        at com.sun.net.ssl.internal.pkcs12.PKCS12KeyStore.engineGetKey(Unknown Source)         at java.security.KeyStoreSpi.engineGetEntry(Unknown Source)         at java.security.KeyStore.getEntry(Unknown Source)         at sun.security.tools.KeyTool.recoverEntry(Unknown Source)         at sun.security.tools.KeyTool.doImportKeyStoreSingle(Unknown Source)         at sun.security.tools.KeyTool.doImportKeyStore(Unknown Source)         at sun.security.tools.KeyTool.doCommands(Unknown Source)         at sun.security.tools.KeyTool.run(Unknown Source)         at sun.security.tools.KeyTool.main(Unknown Source) Caused by: java.security.NoSuchAlgorithmException: EC KeyFactory not available         at java.security.KeyFactory.<init>(Unknown Source)         at java.security.KeyFactory.getInstance(Unknown Source)         ... 9 more 4.2 Create a new PKCS11 provider If you didn't get an error as shown above skip this step. Since we already have NSS libraries built with ECC, we can create a new PKCS11 provider Create ${java.home}/jre/lib/security/nss.cfg as follows: name = NSS     nssLibraryDirectory = ${nsslibdir}    nssDbMode = noDb    attributes = compatibility where nsslibdir should contain NSS libs with ECC support. Add the following line to ${java.home}/jre/lib/security/java.security :      security.provider.9=sun.security.pkcs11.SunPKCS11 ${java.home}/lib/security/nss.cfg Note that those who are using Oracle iPlanet Web Server or Oracle Traffic Director, NSS libs built with ECC are in <ws_install_dir>/lib or <otd_install_dir>/lib. 4.3. Now keytool should work Now you can try the same keytool command and see that it succeeds : $JAVA_HOME/bin/keytool -importkeystore -srckeystore ecc-cert.p12 -srcstoretype PKCS12 -deststoretype JKS -destkeystore ecc.jks -srcstorepass password -deststorepass password -srcalias ecc-cert -destalias ecc-cert -srckeypass password -destkeypass password -v [Storing ecc.jks] 5. Convert JKS keystore into an Oracle Wallet You can export this cert and key from JKS keystore and import it into an Oracle Wallet if you need using orapki tool as shown below. Make sure that orapki you use supports ECC. Also for ECC you MUST use "-jsafe" option. $ orapki wallet create -pwd password  -wallet .  -jsafe $ orapki wallet jks_to_pkcs12 -wallet . -pwd password -keystore ecc.jks -jkspwd password -jsafe AS $orapki wallet display -wallet . -pwd welcome1  -jsafeOracle PKI Tool : Version 11.1.2.0.0Copyright (c) 2004, 2012, Oracle and/or its affiliates.

• MonoGame: PC + Mobile?

  - by ashes999

  I'm researching Monogame. Their goal is to allow "easy" porting of an existing XNA/Windows game to mobile. Does this mean you can have one solution (theoretically) with shared code, and it works on all three platforms (PC, Android, iPhone)? Or do you need to port your game from PC to Android, and then again to iPhone? I'm sure "write once, run anywhere" works 80% of the time, I'm not worried about that other 20% like support for GPS, acceleratometer, etc. which doesn't exist on all platforms.

• Wozu eigentlich Oracle Linux?

  - by Manuel Hossfeld

  Zur Abwechslung gibt es heute mal einen kürzeren Artikel, und zwar zum Thema "Oracle Linux". Der eine oder andere mag sich vielleicht schon mal gefragt haben, warum man sich mit diesem "Red Hat Klon" überhaupt auseinandersetzen sollte. Gibt es neben dem "Support aus einer Hand"-Argument noch andere Gründe, warum sich Kunden dafür entscheiden, Oracle Linux einzusetzen? Diese und ähnliche Fragen hat eine kürzlich erschienene IDC-Studie beleuchtet. Sie trägt den Titel: "Oracle Linux Takes Its Place in the Operating Systems Market". Interessant ist vor allem ein konkretes Kundenbeispiel am Ende der Studie. Da es thematisch gerade passt sei zum Schluss noch ein kleiner Hinweis in eigener Sache erlaubt:Viele der in dem Paper erwähnten Aspekte und Features (wie z.B. KSplice für Reboot-freie Kernel-Updates) werden auch auf der diesjährigen DOAG-Konferenz in Nürnberg behandelt. Mein Kollege Lenz Grimmer und ich halten dort einen Vortrag mit dem Titel: "Oracle Linux - Best Practices und Nutzen (nicht nur) für die Oracle DB"20.11.2012, 15:00 - 15:45 Uhr, Raum Kiew
