• Configuring gmail for use on mailing lists

  - by reemrevnivek

  This is really two questions in one. First, are nettiquette guidelines still accurate in their restrictions on ASCII vs. HTML, posting style, and line length? (Here's a recent metafilter discussion of the topic.) Second, If they are not, should these guidelines be respected? If they are (or if they should still be respected), how can modern mail programs be configured to work properly with them? Most mailing list etiquette statements appear to have been written by sysadmins who loved their command lines, and refuse to change anything. Many still reference rfc1855, written in 1995. Just reading that paginated TXT should give you an idea of the climate at the time. Here's a short, fairly random list of mailing list etiquette statements with some extracted formatting guidelines: Mozilla - HTML discouraged, interleaved posting. FreeBSD - No HTML, don't top post, line length at 75 characters. Fedora - No HTML, bottom-post. You get the idea. You've all seen etiquette statements before. So, assuming that the rules should be obeyed (Usually a good idea), what can be done to allow me to still use a modern mail program, and exchange mail with friends who use the same programs? We like to format our mail. Bold headings, code snippets (sometimes syntax highlighted, if the copy-paste pulls RTF text as from XCOde and Eclipse), free line breaks determined by your browser width, and the (very) occasional image make the message easier to read. Threaded conversations are a wonderful thing. Broadband connections are, I'm sure, the rule for most of the users of SU and of developer mailing lists, disk space is cheap, and so the overhead of HTML is laughable. However, I don't want to post a question to a mailing list and have the guru who can answer my question automatically delete it, or come off as uncaring. Until I hear otherwise, I'll continue to respect the rules as best I can. For a common example of the problem, Gmail, by default, sends HTML formatted messages with bottom-posted quotes (which are folded in, just read the last message immediately above), and uses the frame width to wrap lines, rather than a character count. ASCII can be selected, and quotes can be moved and reversed, but line wraps of quotes don't work, line breaks are tedious to add (and more tedious to read, if they're super small in comparison to the width of the frame). Is there a forwarding, free mail program which can help with this exercise? Should an "RFC1855 mode" lab be written? Or do I have to go to the command line for my mailing lists, and gmail for my other mail?

• Apache refusing to change DocumentRoot

  - by mingos

  I've installed Zend Server CE 5.1.0 on Windows 7 Ultimate 64 bit in its default location, meaning the path to my htdocs is C:\Program Files (x86)\Zend\Apache2\htdocs. Not something that I would like to type each time I check out a project from SVN in Eclipse or something. I'd like to set the DocumentRoot to a different folder, namely D:\www. What I've done I edited conf/httpd.conf, with the significant lines being: DocumentRoot "D:\www" <Directory "D:\www"> Options Indexes FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> Include conf/extra/httpd-vhosts.conf I edited conf/extra/httpd-vhosts.conf to add a virtual host: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot D:\www ServerName localhost ServerAlias localhost SetEnv APPLICATION_ENV development SetEnv APPLICATION_DOMAIN localhost </VirtualHost> <VirtualHost *:80> DocumentRoot D:\www\UmbraCMS ServerName umbracms.local ServerAlias umbracms.local SetEnv APPLICATION_ENV development SetEnv APPLICATION_DOMAIN umbracms.local </VirtualHost> I edited C:\Windows\System32\drivers\etc\hosts to add this line: 127.0.0.1 umbracms.local And I also added a PHP project to D:\www\UmbraCMS. And restarted Apache. Actually, I restarted the computer, too, just in case. What's supposed to happen After typing http://umbracms.local/ in the browser's address bar, I want to see my PHP project launch, obviously. What's actually happening No matter whether whether I type http://umbracms.local/ or http://localhost/, I'm taken to the test zend page, located in C:\Program Files (x86)\Zend\Apache2\htdocs\index.html, as if neither DocumentRoot was changed nor name-based virtual hosting worked. Interestingly, when I put another project in C:\Program Files (x86)\Zend\Apache2\htdocs\bugraid\ and then, in the browser, typed http://localhost/bugraid, the project actually opened, or at least tried to, as it completely ignored the project's .htaccess file. Extra considerations Zend Server's Apache version is 2.2.16, PHP version is 5.3.0 I've installed MySQL CE 5.5.13 separately, and it works, both from command line and via MySQL Workbench. I have XAMPP installed, but none of its components are started up. It's got its own install of Apache 2.2.17 and MySQL 5.5.1. PHP version is 5.3.5 (I think). Question Have you had a similar situation before? What else might need taking care of in order to have Zend Server's Apache use D:\www as document root for my PHP projects?

• Getting an boot error when starting computer

  - by Rob Avery IV

  I was in the middle of watching a movie on Netflix, then suddenly everything started crashing. First, explorer.exe closed down, then Google chrome. I had multiple things running in the background (Steam, Raptr, etc.). Individuality, each of those apps closed down also. When they did, a small dialog box popped up for each of them, one at a time, saying that it was missing a file, it couldn't run anymore, or something similar to that. It also had some jumbled up "code" with numbers and letters that I couldn't read. Ever since then, everytime I turn my computer on, it will run for a few seconds and give this error "Reboot and select proper boot device or insert boot media in selected boot device and press a key_". No matter how many times I try to reboot it, it always gives me the same error. A day later after this happened I was able to start the computer, but before it booted, it told me that I didn't shut down the computer properly and asked how I wanted to run the OS (Run Windows in Safety Mode, Run Windows Normally, etc.). Once I logged, everything went SUPER slow and everything crashed almost instantly. The only thing I opened was Microsoft Security Essentials and only got in about two clicks before it was "Not Responding". Then, after that the whole computer froze and I had to restart it. Now, it's back to saying what it originally said, "Reboot and select proper boot device or insert boot media in selected boot device and press a key_". I built this PC back in February 2012. Here are the specs: OS: Windows 7 Ultimate CPU: AMD 8-core GPU: Nvidia GTX Force 560 Ti RAM: 16GB Hard Drive: Hitachi Deskstar 750GB I'm usually very good taking care of my PC. I don't download anything that's not from a trusted site or source. I don't open up any spam email or such or go to any harmful websites like porn or stream movies. I am very clean with the things I do with my PC and don't do many DIFFERENT things with it. I use it pretty often especially for video games and doing homework in Eclipse. Also, good to note that I don't have any Norton or antisoftware installed. I have Microsoft Security Essentials installed but never did a scan. Thanks!

• Suspected network performance issue on VirtualBox Ubuntu guest on Win7 host

  - by Adam

  I set up Ubuntu 12.04 in VirtualBox on the Win7 machine I was allocated on my new project. I am running Java, Eclipse, Tomcat to develop a large data-intensive application and I noticed that this application runs at half the speed of my colleague's identical machine, where he runs it all under Windows. I think I have narrowed down the performance issue to the network, after comparing and equalising all the Java VM settings with my colleague. Is there a ping test I can do or some other network diagnostic test to flag up any problems? To give some background, the network performance is confusing. Running a network speed test to my colleague's machine with iperf shows speeds of 6 Mb/s from my Ubuntu guest, and 90 Mb/s from the win7 host. Large downloads, e.g. the Java SDK, come down at about 1.2 MB/s on both the guest and the host. Pings are sub-1ms on the host, but 1.5ms on the guest. I also did a broadband speed test, and got 10Mb/s download speed on both, but the host has an upload speed of 10Mb/s but the guest only uploads at 3Mb/s. I've been trying to diagnose any MTU problems with ping -M do to identify any kind of packet fragmentation problem but it's progressing very slow because I don't have much experience in this area. From what I read on other people's networking issues with VB and Linux guests on Win7 hosts, I should be able to get the speed on the guest up to the same level as the host. I installed a fresh VM with Ubuntu again to see if I'd foobar'd it somehow, but I'm getting the same readings with iperf on the virgin installation. My setup is: Adapter 1: Intel PRO/1000 MT Desktop (NAT) Adapter 2: ditto (host-only adapter) eth0 Link encap:Ethernet HWaddr 08:00:27:0b:76:bf inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fe0b:76bf/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:86236 errors:0 dropped:0 overruns:0 frame:0 TX packets:49369 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:69163946 (69.1 MB) TX bytes:3530535 (3.5 MB) eth2 Link encap:Ethernet HWaddr 08:00:27:a3:26:b8 inet addr:192.168.56.101 Bcast:192.168.56.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fea3:26b8/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:59 errors:0 dropped:0 overruns:0 frame:0 TX packets:57 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:9148 (9.1 KB) TX bytes:7648 (7.6 KB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:701 errors:0 dropped:0 overruns:0 frame:0 TX packets:701 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:66321 (66.3 KB) TX bytes:66321 (66.3 KB)

• 2010 Collaboration Summit Impressions

  It's a bit late, but there you have it anyway. April 14 to 16 I attended the Linux Foundation Collaboration Summit in SFO. I was running two tracks, one on tracing and one on tools. You can see the tracks and the slides here: http://events.linuxfoundation.org/events/collaboration-summit/slides I was pretty busy both days, Thursday with a whole day tracing track, Friday with a half day toolchain track. The sessions were well attended, the rooms were full, with people spilling in the hallways. Some new things were presented, like Kernelshark, by Steve Rostedt, a GUI (yes, believe it or not, a GUI) written in GTK. It is very nice, showing a timeline for traced kernel events, and you can zoom in and filter at will. It works on the latest kernels, and it requires some new things/fixes in GTK. I don't recall exactly what version of GTK though. Dominique Toupin from Ericsson presented something about user requirements for tracing. Mostly though about who's who in the embedded world, and eclipse. Masami and Mathieu presented an update on their work. See their slides. The interesting thing to me was of course the new version of uprobes w/o underlying utrace presented by Jim Keniston. At the end of the session we had a discussion about the future of utrace. Roland wasn't there, butTom Tromey (also from RedHat) collected the feedback. Basically we are at a standstill now that utrace has been rejected yet again. There wasn't much advise that anybody could give, except jokingly, we decided that the only way in is to make it a part of perf events. There needs to be another refactoring, but most of all, this "killer app" that would be enabled because of utrace hasn't materialized yet. We think that having a good debugging story on Linux is enough of a killer app, for instance allowing multiple tracers, and not relying on SIGCHLD etc. I think this wasn't completely clear to the kernel community. Trying to achieve debugging via a gdb stub inside the kernel interfacing to utrace and that is controlled via the gdb remote protocol also lost its appeal (thankfully, since the gdb remote protocol is archaic). Somebody would have to be creative in how to submit utrace. It doesn't have to be called utrace (it was really a random choice, for lack of a letter that was not already used in front of the word "trace"). So basically, I think the ideas behind utrace are sound, and the necessity of a new interface is acknowledged. But I believe the integration/submission process with the kernel folks has to restart from scratch, clean slate. We'll see. There are many conferences and meetings coming up in the near future where things can be discussed further. On the second day, Friday, we had the tools talks. It was interesting to observe the more "kernel" oriented people's behavior towards the gcc etc community. The first talk was by Mark Mitchell, about Gcc and its new plugin architecture. After that, Paolo talked about the new C++1x standard, which will be finalized in 2011. Many features are already implemented in the libstdc++ library and gcc and usable today. We had a few minutes (really, the half day track was quite short) where Bradley Kuhn from the Software Freedom Law Center explained the GPLv3 exception for gcc (due to the new gcc plugin architecture and the availability of the intermediate results from the compilation, which is a new thing). I will not try to explain, but basically you cannot take the result of the preprocessing and then use that in your own proprietary compiler. After, we had a talk by Ian Taylor about the new Gold linker. One good thing in that area is that they are trying to make gold the new default linker (for instance Fedora will use gold as the distro linker). However gold is very different from binutils' old linker. It doesn't use a linker script, for instance. The kernel has been linked with gold many times as an exercise (the ground work was done by Kris Van Hees), but this needs to be constantly tested/monitored because the kernel linker script is very complex, and uses esoteric features (Wenji is now monitoring that each kernel RC can be built with gold). It was positive that people are now aware of gold and the need for it to be ported to more architectures. It seems that the porting is very easy, with little arch dependent code. Finally Tom Tromey presented about gdb and the archer project. Archer is a development branch of gdb mostly done by RedHat, where they are focusing on better c++ printing, c++ expression parsing, and plugins. The archer work is merged regularly in the gdb mainline. In general it was a good conference. I did miss most of the first day, because that's when I flew in. But I caught a couple of talks. Nothing earth shattering, except for Google giving each person registered a free Android phone. Yey.

• Installing SOA Suite 11.1.1.3

  - by James Taylor

  With the release of Oracle SOA Suite 11.1.1.3 last week (28 April 2010) I thought I would attempt to implement a complete SOA Environment with SOA Suite, BPM and OSB on the WLS infrastructure. One major point of difference with the 11.1.1.3 is that is is released as a point release so you must have 11.1.1.2 installed first, then upgrade to 11.1.1.3. This post is performing the upgrade on Linux, if upgrading on windows you will need to substitute the directories and files accordingly. This post assumes that you have SOA Suite 11.1.1.2 installed already. 1. Download 11.1.1.3 software from the following site: http://www.oracle.com/technology/software/products/middleware/htdocs/fmw_11_download.html WLS 11.1.1.3   RCU 11.1.1.3 SOA Suite 11.1.1.3 OSB 11.1.1.3 Copy files to a staging area. For the purpose of this document the staging area is: /u01/stage  2. Shutdown your existing SOA Suite 11.1.1.2 environment 3. Execute the WLS 11.1.1.3 install from the stage directory. wls1033_linux32.bin 4. Choose the existing 11.1.1.2 Middleware Home 5. Ignore the security update notification 6. Accept the default products to be upgraded. 7. Upgrade of WebLogic has been completed   8. Upgrade the SOA Suite database schemas using the RCU utility. Unzip the RCU utility into the staging area and run the install ./u01/stage/rcuHome/bin/rcu 9. Drop the existing Repository and provide connection details 9. Install SOA Suite patch set 11.1.1.3. Unzip the SOA Suite patchset and execute the runInstaller with the following command. ./u01/stage/Disk1/runInstaller –jreLoc $MW_HOME/jdk160_18/jre 10. Choose the existing 11.1.1.2 middleware home 11. Start Install 12. Your SOA Suite Install should now be completed. Now we need to update the database repository. Login to SQLPlus as sysdba and execute the following command. SELECT version, status FROM schema_version_registry where owner = 'DEV_SOAINFRA'; the result should be similar to this: VERSION                        STATUS      OWNER ------------------------------ ----------- ------------------------------ 11.1.1.2.0                     VALID       DEV_SOAINFRA As you can see the version if these repositories are still at 11.1.1.2. 13. To upgrade these versions you have 2 options. 1 install via RCU, but this will remove any existing services. The second option is to use the Patch Set Assistant. From the $MW_HOME directory run the following command ./Oracle_SOA1/bin/psa -dbType Oracle -dbConnectString 'localhost:1521:xe' -dbaUserName sys -schemaUserName DEV_SOAINFRA 14. Install OSB. For the OSB install I did not install the IDE, or the Examples. run the runInstaller from the command line, unzip the OSB download to the stage area. ./u01/stage/osb/Disk1/runInstaller –jreLoc $MW_HOME/jdk160_18/jre 15. Choose Custom Install NOT to install the IDE (Eclipse) or Examples. 16. Unselect the, Examples and IDE checkboxes. 17. Accept the defaults and start installing. 18. Once the install has been completed configure the domain by running the Configuration Wizard. $MW_HOME/oracle_common/common/bin/config.sh You can create a new domain. In this document I will extend the soa_domain. 19. Select the following from the check list. I have selected the BPM Suite, this is unrelated to OSB but wanted it for my development purposes. To use this functionality additional license are required. 20. Configure the database connectivity. 21. Configure the database connectivity for the OSB schema. 22. Accept the defaults if installing on standard machine, if you require a cluster or advanced configuration then choose the option for you. 23. Upgrade is complete and OSB has been installed. Now you can start your environment.

• How to build Open JavaFX for Android.

  - by PictureCo

  Here's a short recipe for baking JavaFX for Android dalvik. We will need just a few ingredients but each one requires special care. So let's get down to the business.  SourcesThe first ingredient is an open JavaFX repository. This should be piece of cake. As always there's a catch. You probably know that dalvik is jdk6 compatible  and also that certain APIs are missing comparing to good old java vm from Oracle.  Fortunately there is a repository which is a backport of regular OpenJFX to jdk7 and going from jdk7 to jdk6 is possible. The first thing to do is to clone or download the repository from https://bitbucket.org/narya/jfx78. Main page of the project says "It works in some cases" so we will presume that it will work in most cases As I've said dalvik vm misses some APIs which would lead to a build failures. To get them use another compatibility repository which is available on GitHub https://github.com/robovm/robovm-jfx78-compat. Download the zip and unzip sources into jfx78/modules/base.We need also a javafx binary stubs. Use jfxrt.jar from jdk8.The last thing to download are freetype sources from http://freetype.org. These will be necessary for native font rendering. Toolchain setup I have to point out that these instructions were tested only on linux. I suppose they will work with minimal changes also on Mac OS. I also presume that you were able to build open JavaFX. That means all tools like ant, gradle, gcc and jdk8 have been installed and are working all right. In addition to this you will need to download and install jdk7, Android SDK and Android NDK for native code compilation.  Installing all of them will take some time. Don't forget to put them in your path. export ANDROID_SDK=/opt/android-sdk-linux export ANDROID_NDK=/opt/android-ndk-r9b export JAVA_HOME=/opt/jdk1.7.0 export PATH=$JAVA_HOME/bin:$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools:$ANDROID_NDK FreetypeUnzip freetype release sources first. We will have to cross compile them for arm. Firstly we will create a standalone toolchain for cross compiling installed in ~/work/ndk-standalone-19. $ANDROID_NDK/build/tools/make-standalone-toolchain.sh  --platform=android-19 --install-dir=~/work/ndk-standalone-19 After the standalone toolchain has been created cross compile freetype with following script: export TOOLCHAIN=~/work/freetype/ndk-standalone-19 export PATH=$TOOLCHAIN/bin:$PATH export FREETYPE=`pwd` ./configure --host=arm-linux-androideabi --prefix=$FREETYPE/install --without-png --without-zlib --enable-shared sed -i 's/\-version\-info \$(version_info)/-avoid-version/' builds/unix/unix-cc.mk make make install It will compile and install freetype library into $FREETYPE/install. We will link to this install dir later on. It would be possible also to link openjfx font support dynamically against skia library available on Android which already contains freetype. It creates smaller result but can have compatibility problems. Patching Download patches javafx-android-compat.patch + android-tools.patch and patch jfx78 repository. I recommend to have look at patches. First one android-compat.patch updates openjfx build script, removes dependency on SharedSecret classes and updates LensLogger to remove dependency on jdk specific PlatformLogger. Second one android-tools.patch creates helper script in android-tools. The script helps to setup javaFX Android projects. Building Now is time to try the build. Run following script: JAVA_HOME=/opt/jdk1.7.0 JDK_HOME=/opt/jdk1.7.0 ANDROID_SDK=/opt/android-sdk-linux ANDROID_NDK=/opt/android-ndk-r9b PATH=$JAVA_HOME/bin:$ANDROID_SDK/tools:$ANDROID_SDK/platform-tools:$ANDROID_NDK:$PATH gradle -PDEBUG -PDALVIK_VM=true -PBINARY_STUB=~/work/binary_stub/linux/rt/lib/ext/jfxrt.jar \ -PFREETYPE_DIR=~/work/freetype/install -PCOMPILE_TARGETS=android If everything went all right the output is in build/android-sdk Create first JavaFX Android project Use gradle script int android-tools. The script sets the project structure for you.   Following command creates Android HelloWorld project which links to a freshly built javafx runtime and to a HelloWorld application. NAME is a name of Android project. DIR where to create our first project. PACKAGE is package name required by Android. It has nothing to do with a packaging of javafx application. JFX_SDK points to our recently built runtime. JFX_APP points to dist directory of javafx application. (where all application jars sit) JFX_MAIN is fully qualified name of a main class. gradle -PDEBUG -PDIR=/home/user/work -PNAME=HelloWorld -PPACKAGE=com.helloworld \ -PJFX_SDK=/home/user/work/jfx78/build/android-sdk -PJFX_APP=/home/user/NetBeansProjects/HelloWorld/dist \ -PJFX_MAIN=com.helloworld.HelloWorld createProject Now cd to the created project and use it like any other android project. ant clean, debug, uninstall, installd will work. I haven't tried it from any IDE Eclipse nor Netbeans. Special thanks to Stefan Fuchs and Daniel Zwolenski for the repositories used in this blog post.

• Running Jetty under Windows Azure Using RoleEntryPoint in a Worker Role

  - by Shawn Cicoria

  This post is built upon the work of Mario Kosmiskas and David C. Chou’s prior postings – from here: http://blogs.msdn.com/b/mariok/archive/2011/01/05/deploying-java-applications-in-azure.aspx  http://blogs.msdn.com/b/dachou/archive/2010/03/21/run-java-with-jetty-in-windows-azure.aspx As Mario points out in his post, when you need to have more control over the process that starts, it generally is better left to a RoleEntryPoint capability that as of now, requires the use of a CLR based assembly that is deployed as part of the package to Azure. There were things I liked especially about Mario’s post – specifically, the ability to pull down the JRE and Jetty runtimes at role startup and instantiate the process using the extracted bits.  The way Mario initialized the java process (and Jetty) was to take advantage of a role startup task configured as part of the service definition.  This is a great quick way to kick off processes or tasks prior to your role entry point.  However, if you need access to service configuration values or role events, that’s where RoleEntryPoint comes in.  For this PoC sample I moved the logic for retrieving the bits for the jre and jetty to the worker roles OnStart – in addition to moving the process kickoff to the OnStart method.  The Run method at this point is there to loop and just report the status of the java process. Beyond just making things more parameterized, both Mario’s and David’s articles still form the essence of the approach. The solution that accompanies this post provides all the necessary .NET based Visual Studio project.  In addition, you’ll need: 1. Jetty 7 runtime http://www.eclipse.org/jetty/downloads.php 2. JRE http://www.oracle.com/technetwork/java/javase/downloads/index.html Once you have these the first step is to create archives (zips) of the distributions.  For this PoC, the structure of the archive requires that the root of the archive looks as follows: JRE6.zip jetty---.zip Upload the contents to a storage container (block blob), and for this example I used /archives as the location.  The service configuration has several settings that allow, which is the advantage of using RoleEntryPoint, the ability to provide these things via native configuration support from Azure in a worker role. Storage Explorer You can use development storage for testing this out – the zipped version of the solution is configured for development storage.  When you’re ready to deploy, you update the two settings – 1 for diagnostics and the other for the storage container where the /archives are going to be stored. <?xml version="1.0" encoding="utf-8"?> <ServiceConfiguration serviceName="HostedJetty" osFamily="2" osVersion="*"> <Role name="JettyWorker"> <Instances count="1" /> <ConfigurationSettings> <!--<Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="DefaultEndpointsProtocol=https;AccountName=<accountName>;AccountKey=<accountKey>" />--> <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" /> <Setting name="JettyArchive" value="jetty-distribution-7.3.0.v20110203b.zip" /> <Setting name="StartRole" value="true" /> <Setting name="BlobContainer" value="archives" /> <Setting name="JreArchive" value="jre6.zip" /> <!--<Setting name="StorageCredentials" value="DefaultEndpointsProtocol=https;AccountName=<accountName>;AccountKey=<accountKey>"/>--> <Setting name="StorageCredentials" value="UseDevelopmentStorage=true" />   For interacting with Storage you can use several tools – one tool that I like is from the Windows Azure CAT team located here: http://appfabriccat.com/2011/02/exploring-windows-azure-storage-apis-by-building-a-storage-explorer-application/  and shown in the prior picture At runtime, during role initialization and startup, Azure will call into your RoleEntryPoint.  At that time the code will do a dynamic pull of the 2 archives and extract – using the Sharp Zip Lib <link> as Mario had demonstrated in his sample.  The only different here is the use of CLR code vs. PowerShell (which is really CLR, but that’s another discussion). At this point, once the 2 zips are extracted, the Role’s file system looks as follows: Worker Role approot From there, the OnStart method (which also does the download and unzip using a simple StorageHelper class) kicks off the Java path and now you have Java! Task Manager Jetty Sample Page A couple of things I’m working on to enhance this is to extract the jre and jetty bits not to the appRoot but to a resource location defined as part of the service definition. ServiceDefinition.csdef <?xml version="1.0" encoding="utf-8"?> <ServiceDefinition name="HostedJetty" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition"> <WorkerRole name="JettyWorker"> <Imports> <Import moduleName="Diagnostics" /> <Import moduleName="RemoteAccess" /> <Import moduleName="RemoteForwarder" /> </Imports> <Endpoints> <InputEndpoint name="JettyPort" protocol="tcp" port="80" localPort="8080" /> </Endpoints> <LocalResources> <LocalStorage name="Archives" cleanOnRoleRecycle="false" sizeInMB="100" /> </LocalResources>   As the concept matures a bit, being able to update dynamically the content or jar files as part of a running java solution is something that is possible through continued enhancement of this simple model. The Visual Studio 2010 Solution is located here: HostingJavaSln_NDA.zip

• using Unity Android In a sub view and add actionbar and style

  - by aeroxr1

  I exported a simple animation from Unity3D (version 4.5) in android project. With eclipse I modified the manifest and added another activity. In this activity I put a button that it makes start the animation,and this is the result. The action bar appear in the main activity but it doesn't in the unity's activity :( How can I add the action bar and the style of the first activity to unity's animation activity ? This is the unity's activity's code : package com.rabidgremlin.tut.redcube; import android.app.NativeActivity; import android.content.res.Configuration; import android.graphics.PixelFormat; import android.os.Bundle; import android.view.KeyEvent; import android.view.MotionEvent; import android.view.View; import android.view.ViewGroup; import android.view.Window; import android.view.WindowManager; import com.unity3d.player.UnityPlayer; public class UnityPlayerNativeActivity extends NativeActivity { protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code // Setup activity layout @Override protected void onCreate (Bundle savedInstanceState) { //requestWindowFeature(Window.FEATURE_NO_TITLE); super.onCreate(savedInstanceState); getWindow().takeSurface(null); //setTheme(android.R.style.Theme_NoTitleBar_Fullscreen); getWindow().setFormat(PixelFormat.RGB_565); mUnityPlayer = new UnityPlayer(this); /*if (mUnityPlayer.getSettings ().getBoolean ("hide_status_bar", true)) getWindow ().setFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); */ setContentView(mUnityPlayer); mUnityPlayer.requestFocus(); } // Quit Unity @Override protected void onDestroy () { mUnityPlayer.quit(); super.onDestroy(); } // Pause Unity @Override protected void onPause() { super.onPause(); mUnityPlayer.pause(); } // eliminiamo questa onResume() e proviamo a modificare la onResume() // Resume Unity @Override protected void onResume() { super.onResume(); mUnityPlayer.resume(); } // inseriamo qualche modifica qui // This ensures the layout will be correct. @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); mUnityPlayer.configurationChanged(newConfig); } // Notify Unity of the focus change. @Override public void onWindowFocusChanged(boolean hasFocus) { super.onWindowFocusChanged(hasFocus); mUnityPlayer.windowFocusChanged(hasFocus); } // For some reason the multiple keyevent type is not supported by the ndk. // Force event injection by overriding dispatchKeyEvent(). @Override public boolean dispatchKeyEvent(KeyEvent event) { if (event.getAction() == KeyEvent.ACTION_MULTIPLE) return mUnityPlayer.injectEvent(event); return super.dispatchKeyEvent(event); } // Pass any events not handled by (unfocused) views straight to UnityPlayer @Override public boolean onKeyUp(int keyCode, KeyEvent event) { return mUnityPlayer.injectEvent(event); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { return mUnityPlayer.injectEvent(event); } @Override public boolean onTouchEvent(MotionEvent event) { return mUnityPlayer.injectEvent(event); } /*API12*/ public boolean onGenericMotionEvent(MotionEvent event) { return mUnityPlayer.injectEvent(event); } } And this is the AndroidManifest.xml android:versionCode="1" android:versionName="1.0" > <!-- android:theme="@android:style/Theme.NoTitleBar"--> <supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:smallScreens="true" android:xlargeScreens="true" /> <application android:icon="@drawable/app_icon" android:label="@string/app_name" android:theme="@android:style/Theme.Holo.Light" > <activity android:name="com.rabidgremlin.tut.redcube.UnityPlayerNativeActivity" android:configChanges="mcc|mnc|locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|screenLayout|uiMode|screenSize|smallestScreenSize|fontScale" android:label="@string/app_name" android:screenOrientation="portrait" > <!--android:launchMode="singleTask"--> <meta-data android:name="unityplayer.UnityActivity" android:value="true" /> <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="false" /> </activity> <activity android:name="com.rabidgremlin.tut.redcube.MainActivity" android:label="@string/title_activity_main" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="17" android:targetSdkVersion="19" /> <uses-feature android:glEsVersion="0x00020000" /> </manifest>

• A little primer on using TFS with a small team

  - by johndoucette

  The scenario; A small team of 3 developers mostly in maintenance mode with traditional ASP.net, classic ASP, .Net integration services and utilities with the company’s third party packages, and a bunch of java-based Coldfusion web applications all under Visual Source Safe (VSS). They are about to embark on a huge SharePoint 2010 new construction project and wanted to use subversion instead VSS. TFS was a foreign word and smelled of “high cost” and of an “over complicated process”. Since they had no preconditions about the old TFS versions (‘05 & ‘08), it was fun explaining how simple it was to install a TFS server and get the ball rolling, with or without all the heavy stuff one sometimes associates with such a huge and powerful application management lifecycle product. So, how does a small team begin using TFS? 1. Start by using source control and migrate current VSS source trees into TFS. You can take the latest version or migrate the entire version history. It’s up to you on whether you want a clean start or need quick access to all the version notes and history of the bits. 2. Since most shops are mainly in maintenance mode with existing applications, begin using bug workitems for everything. When you receive an issue/bug from your current tracking system, manually enter the workitem in TFS right through Visual Studio. You can automate the integration to the current tracking system later or replace it entirely. Believe me, this thing is powerful and can handle even the largest of help desks. 3. With new construction, begin work with requirements and task workitems and follow the traditional sprint-based development lifecycle. Obviously, some minor training will be needed, but don’t fear, this is very intuitive and MSDN has a ton of lesson based labs and videos. 4. For the java developers, use the new Team Explorer Everywhere 2010 plugin (recently known as Teamprise). There is a seamless interface in Eclipse, but also a good command-line utility for other environments such as Dreamweaver. 5. Wait to fully integrate the whole workitem/project management/testing process until your team is familiar with the integrated workitems for bugs and code. After a while, you will see the team wanting more transparency into the work they are all doing and naturally, everyone will want workitems to help them organize the chaos! 6. Management will be limited in the value of the reports until you have a fully blown implementation of project planning, construction, build, deployment and testing. However, there are some basic “bug rate” reports and current backlog listings that can provide good information. Some notable explanations of TFS; Work Item Tracking and Project Management - A workitem represents the unit of work within the system which enables tracking of all activities produced by a user, whether it is a developer, business user, project manager or tester. The properties of a workitem such as linked changesets (checked-in code), who updated the data and when, the states and reasons for change, are all transitioned to a data warehouse within TFS for reporting purposes. A workitem can be defines as a "bug", "requirement", test case", or a "change request". They drive the work effort by the individual assigned to it and also provide a key role in defining what needs to be done. Workitems are the things the team needs to do to accomplish a goal. Test Case Management - Starting with a workitem known as a "test case", a tester (or developer) can now author and manage test cases within a formal test plan subsystem. Although TFS supports the test case workitem type, there is a new product known as the VS Test Professional 2010 which allows a tester to facilitate manual tests including fast forwarding steps in the process to arrive at the assertion point quickly. This repeatable process provides quick regression tests and can be conducted by the business user to ensure completeness during UAT. In addition, developers no longer can provide a response to a bug with the line "cannot reproduce". With every test run, attachments including the recorded session, captured environment configurations and settings, screen shots, intellitrace (debugging history), and in some cases if the lab manager is being used, a snapshot of the tested environment is available. Version Control - A modern system allowing shared check-in/check-out, excellent merge conflict resolution, Shelvesets (personal check-ins), branching/merging visualization, public workspaces, gated check-ins, security hierarchy capabilities, and changeset/workitem tracking. Knowing what was done with the code by any developer has become much easier to picture and resolve issues. Team Build - Automate the compilation process whether you need it to be whenever a developer checks-in code, periodically such as nightly builds for testers in the morning, or manual builds to be deployed into production. Each build can run through pre-determined tests, perform code analysis to see if the developer conforms to the team standards, and reject the build if either fails. Project Portal & Reporting - Provide management with a dashboard with insight into the project(s). "Where are we" in each step of the way including past iterations and the current burndown rate. Enabling this feature is easy as it seamlessly interfaces with existing SharePoint implementations.

• Oracle Fusion Middleware gives you Choice and Portability for Public and Private Cloud

  - by Michelle Kimihira

  Author: Margaret Lee, Senior Director, Product Management, Oracle Fusion Middleware Cloud Computing allows customers to quickly develop and deploy applications in a shared environment.  The environment can span across hardward (IaaS), foundation layer software (PaaS), and end-user software (SaaS). Cloud Computing provides compelling benefits in terms of business agility and IT cost savings.  However, with complex, existing heterogeneous architectures, and concerns for security and manageability, enterprises are challenged to define their Cloud strategy.  For most enterprises, the solution is a hybrid of private and public cloud.  Fusion Middleware supports customers’ Cloud requirements through choice and portability. Fusion Middleware supports a variety of cloud development and deployment models:  Oracle [Public] Cloud; customer private cloud; hybrid of these two, and traditional dedicated, on-premise model Customers can develop applications in any of these models and deployed in another, providing the flexibility and portability they need Oracle Cloud is a public cloud offering.  Within Oracle Cloud, Fusion Middleware provides two key offerings include the Developer cloud service and Java cloud deployment service. Developer Cloud Service Simplify Development: Automated provisioned environment; pre-configured and integrated; web-based administration Deploy Automatically: Fully integrated with Oracle Cloud for Java deployment; workflow ensures build & test Collaborate & Manage: Fits any size team; integrated team source repository; continuous integration; task/defect tracking Integrated with all major IDEs: Oracle JDeveloper; NetBeans; Eclipse Java Cloud Service Java Cloud service provides flexible Java deployment environment for departmental applications and development, staging, QA, training, and demo environments.  It also supports customizations deployments for SaaS-based Fusion Applications customers.  Some key features of Java Cloud Service include: WebLogic Server on Exalogic, secure, highly available infrastructure Database Service & IDE Integration Open, Standard-based Deploy Web Apps, Web Services, REST Services Fully managed and supported by Oracle For more information, please visit Oracle Cloud, Oracle Cloud Java Service and Oracle Cloud Developer Service. If your enterprise prefers a private cloud, for reasons such as security, control, manageability, and complex integration that prevent your applications from being deployed on a public cloud, Fusion Middleware also provide you with the products and tools you need.  Sometimes called Private PaaS, private clouds have their predecessors in shared-services arrangements many large companies have been building in the past decade.  The difference, however, are in the scope of the services, and depth of their capabilities.  In terms of vertical stack depth, private clouds not only provide hardware and software infrastructure to run your applications, they also provide services such as integration and security, that your applications need.  Horizontally, private clouds provide monitoring, management, lifecycle, and charge back capabilities out-of-box that shared-services platforms did not have before. Oracle Fusion Middleware includes the complete stack of hardware and software for you to build private clouds: SOA suite and BPM suite to support systems integration and process flow between applications deployed on your private cloud and the rest of your organization Identity and Access Management suite to provide security, provisioning, and access services for applications deployed on your private cloud WebLogic Server to run your applications Enterprise Manager's Cloud Management pack to monitor, manage, upgrade applications running on your private cloud Exalogic or optimized Oracle-Sun hardware to build out your private cloud The most important key differentiator for Oracle's cloud solutions is portability, between private and public clouds.  This is unique to Oracle because portability requires the vendor to have product depth and breadth in both public cloud services and private cloud product offerings.  Most public cloud vendors cannot provide the infrastructure and tools customers need to build their own private clouds.  In reverse, traditional software tools vendors typically do not have the product and expertise breadth to build out and offer a public cloud.  Oracle can.  It is important for customers that the products and technologies  Oracle uses to build its public is the same set that it sells to customers for them to build private clouds.  Fundamentally, that enables skills reuse,  as well as application portability.

• Five development tools I can't live without

  - by bconlon

  When applying to join Geeks with Blogs I had to specify the development tools I use every day. That got me thinking, it's taken a long time to whittle my tools of choice down to the selection I use, so it might be worth sharing. Before I begin, I appreciate we all have our preferred development tools, but these are the ones that work for me. Microsoft Visual Studio Microsoft Visual Studio has been my development tool of choice for more years than I care to remember. I first used this when it was Visual C++ 1.5 (hats off to those who started on 1.0) and by 2.2 it had everything I needed from a C++ IDE. Versions 4 and 5 followed and if I had to guess I would expect more Windows applications are written in VC++ 6 and VB6 than any other language. Then came the not so great versions Visual Studio .Net 2002 (7.0) and 2003 (7.1). If I'm honest I was still using v6. 2005 was better and 2008 was simply brilliant. Everything worked, the compiler was super fast and I was happy again...then came 2010...oh dear. 2010 is a big step backwards for me. It's not encouraging for my upcoming WPF exploits that 2010 is fronted in WPF technology, with the forever growing Find/Replace dialog, the issues with C++ intellisense, and the buggy debugger. That said it is still my tool of choice but I hope they sort the issue in SP1. I've tried other IDEs like Visual Age and Eclipse, but for me Visual Studio is the best. A really great tool. Liquid XML Studio XML development is a tricky business. The W3C standards are often difficult to get to the bottom of so it's great to have a graphical tool to help. I first used Liquid Technologies 5 or 6 years back when I needed to process XML data in C++. Their excellent XML Data Binding tool has an easy to use Wizard UI (as compared to Castor or JAXB command line tools) and allows you to generate code from an XML Schema. So instead of having to deal with untyped nodes like with a DOM parser, instead you get an Object Model providing a custom API in C++, C#, VB etc. More recently they developed a graphical XML IDE with XML Editor, XSLT, XQuery debugger and other XML tools. So now I can develop an XML Schema graphically, click a button to generate a Sample XML document, and click another button to run the Wizard to generate code including a Sample Application that will then load my Sample XML document into the generated object model. This is a very cool toolset. Note: XML Data Binding is nothing to do with WPF Data Binding, but I hope to cover both in more detail another time. .Net Reflector Note: I've just noticed that starting form the end of February 2011 this will no longer be a free tool !! .Net Reflector turns .Net byte code back into C# source code. But how can it work this magic? Well the clue is in the name, it uses reflection to inspect a compiled .Net assembly. The assembly is compiled to byte code, it doesn't get compiled to native machine code until its needed using a just-in-time (JIT) compiler. The byte code still has all of the information needed to see classes, variables. methods and properties, so reflector gathers this information and puts it in a handy tree. I have used .Net Reflector for years in order to understand what the .Net Framework is doing as it sometimes has undocumented, quirky features. This really has been invaluable in certain instances and I cannot praise enough kudos on the original developer Lutz Roeder. Smart Assembly In order to stop nosy geeks looking at our code using a tool like .Net Reflector, we need to obfuscate (mess up) the byte code. Smart Assembly is a tool that does this. Again I have used this for a long time. It is very quick and easy to use. Another excellent tool. Coincidentally, .Net Reflector and Smart Assembly are now both owned by Red Gate. Again kudos goes to the original developer Jean-Sebastien Lange. TortoiseSVN SVN (Apache Subversion) is a Source Control System developed as an open source project. TortoiseSVN is a graphical UI wrapper over SVN that hooks into Windows Explorer to enable files to be Updated, Committed, Merged etc. from the right click menu. This is an essential tool for keeping my hard work safe! Many years ago I used Microsoft Source Safe and I disliked CVS type systems. But TortoiseSVN is simply the best source control tool I have ever used. --- So there you have it, my top 5 development tools that I use (nearly) every day and have helped to make my working life a little easier. I'm sure there are other great tools that I wish I used but have never heard of, but if you have not used any of the above, I would suggest you check them out as they are all very, very cool products. #

• VirtualBox appliance for the Oracle Communications Service Delivery Platform (SDP) Products

  - by chlander

  It's been quite awhile since we last blogged. This blog is written by Leif Lourie, a Curriculum Developer for the Oracle Communications Service Delivery Platform (SDP) products. For the last 8 years, Leif has worked as a Curriculum Developer for many of the telecom-oriented products that Oracle offers. He has been working in the telecom industry for about 25 years and has also worked as a software developer, project manager, and solutions architect. He is currently working on courseware for an upcoming release for one of the Service Delivery Platform products. Thanks to Leif not only for this blog, but for making the VM described in the blog available. Cheryl Lander, Oracle Communications InfoDev Senior Director To be able to download, install and test a product within a day is many times very important for people that are doing the primary evaluation of a software product. If it takes longer, it will require a bigger effort, like a proof-of-concept project with many people involved. Of course, if the product is chosen for a more thorough test, it will probably happen anyway, but then maybe with focus on integration instead of product features. We have a long tradition of creating complex software that is easy to install and test and we have often been praised for the ease of getting our products up and running. One key for this has been that there has always been an installer for Windows, as well as for the production environments that usually are Unix and Linux. And, the windows installer has, in most cases, been released for developing and testing purposes. Lately, this has changed. Our products are very seldom released for the Windows platform, at all. And even the Linux versions are almost always released for 64-bit systems. This is creating problems for many of the people that want to try out our products, since few have access to a 64-bit Linux system of the right platform. Most of us are using a laptop with Windows or Mac OS. Some of us are using Linux or Solaris, but probably a non certified distribution for the product you want to test. My job, among other things, is to develop hands-on practices for our products. For me, it is crucial to have access to environments for installing and using our products. For this reason I have been using virtual machines for many years.I have a ready-made base system, with the necessary tools installed for all the products I create hands-on practices for. Whenever I start working on hands-on practices for a new product or a new version, I just copy the base system and start working with a clean slate. This saves me a lot of time! Now, I would like to start saving time for my favorite student: You! If you are using our products and regularly test new versions you might benefit from the virtual machine that is now available on Oracle Technology Network: The Virtual Machine for the Oracle Communications Service Delivery Platform (SDP) Products. This virtual machine contains an installation of the 64-bit version of Oracle Enterprise Linux, version 6. It also has Oracle Database Express Edition (XE), Oracle Java and Oracle Enterprise Pack for Eclipse installed. By using Oracle VM VirtualBox you may use Windows, OS X, Linux or Solaris on your laptop. VirtualBox can be installed on top of any of these platforms and give you the ability to run virtual machines in your laptop. After downloading and starting the virtual machine you will also need to download the installation files for the product you want to test; for example Oracle Communications Services Gatekeeper or Oracle Communications Online Mediation Controller. In some cases there are lessons and practices available for the products. The freely available courses are listed in Oracle Learning Library as a Collection of Oracle Communications Service Delivery Platform Courses. As time goes by, we will make this list collection bigger. Also, the goal is to update the virtual machine about one to two times per year. So you will always be able to get a well maintained virtual machine for the Service Delivery Platform products from us. We Value Your Feedback If you would like to suggest improvements or report issues on any of the product documentation, curriculum, or training produced by the Oracle Communications Information Development team, you can use these channels: Email [email protected]. Post a comment on this blog. Thanks for reading!

• Performance issues when using SSD for a developer notebook (WAMP/LAMP stack)?

  - by András Szepesházi

  I'm a web application developer using my notebook as a standalone development environment (WAMP stack). I just switched from a Core2-duo Vista 32 bit notebook with 2Gb RAM and SATA HDD, to an i5-2520M Win7 64 bit with 4Gb RAM and 128 GB SDD (Corsair P3 128). My initial experience was what I expected, fast boot, quick load of all the applications (Eclipse takes now 5 seconds as opposed to 30s on my old notebook), overall great experience. Then I started to build up my development stack, both as LAMP (using VirtualBox with a debian guest) and WAMP (windows native apache + mysql + php). I wanted to compare those two. This still all worked great out, then I started to pull in my projects to these stacks. And here came the nasty surprise, one of those projects produced a lot worse response times than on my old notebook (that was true for both the VirtualBox and WAMP stack). Apache, php and mysql configurations were practically identical in all environments. I started to do a lot of benchmarking and profiling, and here is what I've found: All general benchmarks (Performance Test 7.0, HDTune Pro, wPrime2 and some more) gave a big advantage to the new notebook. Nothing surprising here. Disc specific tests showed that read/write operations peaked around 380M/160M for the SSD, and all the different sized block operations also performed very well. Started apache performance benchmarking with Apache Benchmark for a small static html file (10 concurrent threads, 500 iterations). Old notebook: min 47ms, median 111ms, max 156ms New WAMP stack: min 71ms, median 135ms, max 296ms New LAMP stack (in VirtualBox): min 6ms, median 46ms, max 175ms Right here I don't get why the native WAMP stack performed so bad, but at least the LAMP environment brought the expected speed. Apache performance measurement for non-cached php content. The php runs a loop of 1000 and generates sha1(uniqid()) inisde. Again, 10 concurrent threads, 500 iterations were used for the benchmark. Old notebook: min 0ms, median 39ms, max 218ms New WAMP stack: min 20ms, median 61ms, max 186ms New LAMP stack (in VirtualBox): min 124ms, median 704ms, max 2463ms What the hell? The new LAMP performed miserably, and even the new native WAMP was outperformed by the old notebook. php + mysql test. The test consists of connecting to a database and reading a single record form a table using INNER JOIN on 3 more (indexed) tables, repeated 100 times within a loop. Databases were identical. 10 concurrent threads, 100 iterations were used for the benchmark. Old notebook: min 1201ms, median 1734ms, max 3728ms New WAMP stack: min 367ms, median 675ms, max 1893ms New LAMP stack (in VirtualBox): min 1410ms, median 3659ms, max 5045ms And the same test with concurrency set to 1 (instead of 10): Old notebook: min 1201ms, median 1261ms, max 1357ms New WAMP stack: min 399ms, median 483ms, max 539ms New LAMP stack (in VirtualBox): min 285ms, median 348ms, max 444ms Strictly for my purposes, as I'm using a self contained development environment (= low concurrency) I could be satisfied with the second test's result. Though I have no idea why the VirtualBox environment performed so bad with higher concurrency. Finally I performed a test of including many php files. The application that I mentioned at the beginning, the one that was performing so bad, has a heavy bootstrap, loads hundreds of small library and configuration files while initializing. So this test does nothing else just includes about 100 files. Concurrency set to 1, 100 iterations: Old notebook: min 140ms, median 168ms, max 406ms New WAMP stack: min 434ms, median 488ms, max 604ms New LAMP stack (in VirtualBox): min 413ms, median 1040ms, max 1921ms Even if I consider that VirtualBox reached those files via shared folders, and that slows things down a bit, I still don't see how could the old notebook outperform so heavily both new configurations. And I think this is the real root of the slow performance, as the application uses even more includes, and the whole bootstrap will occur several times within a page request (for each ajax call, for example). To sum it up, here I am with a brand new high-performance notebook that loads the same page in 20 seconds, that my old notebook can do in 5-7 seconds. Needless to say, I'm not a very happy person right now. Why do you think I experience these poor performance values? What are my options to remedy this situation?

• My 3D Games crashing in these scenarios

  - by desaivv

  I have a situation here which I am unable to solve. I bought a PC last year March, here are my specs: Intel Core i3 550 @ 3GHz 4 GB RAM @400 MHz XFX GeForce 9500 GT graphics card 1GB @550MHz 500 GB HDD Lately as soon as I load my save game of Skyrim, it crashes. I have been playing Skyrim since I joined Gaming.SE site. Crashes as in the entire scene gets red lines. I can not ALT + TAB back or even CTRL + ALT + DEL either. My only recourse is a hard reset via the power button. Can not take a screen shot either. I have the latest Forceware 296.10 drivers also. This has been happening since the last 2 weeks. I always use Driver Sweeper to clean my old drivers, since that is what XFXForce recommends before installing new drivers. I installed MSI Afterburner lately to see my GPU temperature. My GPU is default, never over-clocked it. In MSI's Afterburner, I can not adjust fan speed. It is greyed out. Also in settings there is no fan tab. With normal Internet browsing it stays at 51 C. Ran Memtest86 over night with level 11. Took about 13 hours, but no errors in my RAM. I even re-installed my OS, with just the 296 drivers. The fan for the GPU does come on. I can play Diablo 2. I can not get past Warcraft 3's menu selection. There WAS some dust in my machine, but I always try and keep everything clean, since in my home town dust is an issue. Always keep cool my entire PC cabinet. My friend came with his functioning graphics card, we bought our PCs at the same time with exact same specifications. His card did not work either. Same problem with the scene freezing with red lines. I did do my research before posting here. That is how I was able to learn about MSI Afterburner, Driver Sweeper, SpeedFan etc. I followed posts on Tom's Hardware too regarding people that had similar problems. One person suggested and was followed by worked as well the suggestion to "Bake the card in an oven". Since I bought it, played Diablo 2 for months, Starcraft 2 campaign for months and Skyrim recently for months. Bought ME3 also. I am at my wits end. I do not know what else to do. I can go out and buy a card, but my friend's card did not work either. I can use the machine for Eclipse or VS2010 development just fine. Just not with 3D gaming. I originally posted this question on Gaming.SE But I was directed here. I have browsed the SU database for my problem and found this, this, and this. But none of these cover my question. My machine is only one year old. Can some experienced superuser(s) shed some light on this scenario? Is it a 3D graphics card problem? Will a brand new card work? What else can I try to pin point the problem? Can it be the Motherboard? Thanks.

• Sorting Android ListView

  - by aeoth

  I'm only starting with Android dev, and while the Milestone is a nice device Java is not my natural language and I'm struggling with both the Google docs on Android SDK, Eclipse and Java itself. Anyway... I'm writing a microblog client for Android to go along with my Windows client (MahTweets). At the moment I've got Tweets coming and going without fail, the problem is with the UI. The initial call will order items correctly (as in highest to lowest) 3 2 1 When a refresh is made 3 2 1 6 5 4 After the tweets are processed, I'm calling adapter.notifyDataSetChanged(); Initially I thought that getItem() on the Adapter needed to be sorted (and the code below is what I ended up with), but I'm still not having any luck. public class TweetAdapter extends BaseAdapter { private List<IStatusUpdate> elements; private Context c; public TweetAdapter(Context c, List<IStatusUpdate> Tweets) { this.elements = Tweets; this.c = c; } public int getCount() { return elements.size(); } public Object getItem(int position) { Collections.sort(elements, new IStatusUpdateComparator()); return elements.get(position); } public long getItemId(int id) { return id; } public void Remove(int id) { notifyDataSetChanged(); } public View getView(int position, View convertView, ViewGroup parent) { RelativeLayout rowLayout; IStatusUpdate t = elements.get(position); rowLayout = t.GetParent().GetUI(t, parent, c); return rowLayout; } class IStatusUpdateComparator implements Comparator { public int compare(Object obj1, Object obj2) { IStatusUpdate update1 = (IStatusUpdate)obj1; IStatusUpdate update2 = (IStatusUpdate)obj2; int result = update1.getID().compareTo(update2.getID()); if (result == -1) return 1; else if (result == 1) return 0; return result; } } } Is there a better way to go about sorting ListViews in Android, while still being able to use the LayoutInflater? (rowLayout = t.GetParent().GetUI(t, parent, c) expands the UI to the specific view which the microblog implementation can provide)

• android include tag - invalid layout refernce

  - by Dalibor Frivaldsky

  Hello, I'm having a problem including a different layout through the include tag in the android layout xml file. When specifing the layout reference ( @layout/... ), i'm getting a InflateException in the Eclipse ADT with the following error: InflateException: You must specifiy a valid layout reference. The layout ID @layout/func_edit_simple_calculator_toolbox is not valid. the reference should be valid, as I've selected it from the the list of my other layouts and didnt type it in. I'm using android sdk v2.1 these are the layout files func_edit_simple_calculator_toolbox.xml <?xml version="1.0" encoding="utf-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="wrap_content"> <TableRow android:id="@+id/TableRow01" android:layout_width="wrap_content"android:layout_height="wrap_content"> <Button android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="1"></Button> <Button android:id="@+id/Button02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="2"></Button> <Button android:id="@+id/Button03" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="3"></Button> <Button android:id="@+id/Button04" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="+"></Button> </TableRow> <TableRow android:id="@+id/TableRow02" android:layout_width="wrap_content" android:layout_height="wrap_content"> <Button android:id="@+id/Button05" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="4"></Button> <Button android:id="@+id/Button06" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="5"></Button> <Button android:id="@+id/Button07" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="6"></Button> <Button android:id="@+id/Button08" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="-"></Button> </TableRow> </TableLayout> function_editor_layout.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <com.calculoid.FunctionView android:id="@+id/function_view" android:layout_width="fill_parent" android:layout_height="fill_parent"/> <include android:id="@+id/include01" android:layout_width="wrap_content" android:layout_height="wrap_content" layout="@layout/func_edit_simple_calculator_toolbox"></include> </LinearLayout> Does any one know what could be the problem? thanks in advance

• Problem running android HelloTabWidget example - NullPointerException on addTab()

  - by Poindextrose

  I've tried the Tab Layout example, and I've also fixed the few typos in the example (and added all the activities to the manifest). However, when I run it on the emulator I get a NullPointerException on the first line that says tabHost.addTab(spec); So my question, of course, is. What is wrong with the example that would cause this exception? I'm using Eclipse Galileo and set the target package as Android 1.5. So far I've had no other problems with the other examples on the android dev site. package com.example.hellotabwidget; import android.app.TabActivity; import android.content.Intent; import android.content.res.Resources; import android.os.Bundle; import android.widget.TabHost; public class HelloTabWidget extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) throws RuntimeException { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); // Resource object to get Drawables TabHost tabHost = getTabHost(); // The activity TabHost TabHost.TabSpec spec; // Reusable TabSpec for each tab Intent intent; // Reusable Intent for each tab // Create an Intent to launch an Activity for the tab (to be reused) //final Context context = getApplicationContext(); intent = new Intent().setClass(this, ArtistsActivity.class); // Initialize a TabSpec for each tab and add it to the TabHost spec = tabHost.newTabSpec("artists").setIndicator("Artists", res.getDrawable(R.drawable.ic_tab_artists)) .setContent(intent); tabHost.addTab(spec); //******** NullPointerException after running this line // Do the same for the other tabs intent = new Intent().setClass(this, AlbumsActivity.class); spec = tabHost.newTabSpec("albums").setIndicator("Albums", res.getDrawable(R.drawable.ic_tab_artists)) .setContent(intent); tabHost.addTab(spec); intent = new Intent().setClass(this, SongsActivity.class); spec = tabHost.newTabSpec("songs").setIndicator("Songs", res.getDrawable(R.drawable.ic_tab_artists)) .setContent(intent); tabHost.addTab(spec); tabHost.setCurrentTabByTag("artists"); } } main.xml: <?xml version="1.0" encoding="utf-8"?> <TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp"> <TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp" /> </LinearLayout> </TabHost>

• WCF, Rampart, ADFS2 and SAML Interop issue

  - by user317647

  Hi, I'm working on establishing interoperability between .NET WCF 3.5 and Axis2/Rampart using ADFS2 as the STS and using SAML authentication. Initially I used Axis 1.4.1/Rampart 1.4 but in an attempt to rule out issues relating to WS-* standards compatbility have also created a duplicate environment running Axis 1.5.1/Rampart 1.5. Both envionment use Eclipse 3.5.1 (Galileo)/Tomcat 5.5 for the Java service side. My objective is: WCF-ADFS2-SAML token-Axis2/Rampart Using Kerberos authentication to obtain a SAML token from ADFS2 and propagating this to Rampart. Much progress has been made so far, but the error I'm now getting on Rampart is as follows (on both versions 1.4 & 1.5): [ERROR] General security error (SAML token security failure) org.apache.axis2.AxisFault: General security error (SAML token security failure) Caused by: org.apache.ws.security.WSSecurityException: General security error (SAML token security failure) at org.apache.ws.security.saml.SAMLUtil.getSAMLKeyInfo(SAMLUtil.java:169) at org.apache.ws.security.saml.SAMLUtil.getSAMLKeyInfo(SAMLUtil.java:73) at org.apache.ws.security.processor.DerivedKeyTokenProcessor.extractSecret(DerivedKeyTokenProcessor.java:170) at org.apache.ws.security.processor.DerivedKeyTokenProcessor.handleToken(DerivedKeyTokenProcessor.java:74) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:326) at org.apache.ws.security.WSSecurityEngine.processSecurityHeader(WSSecurityEngine.java:243) at org.apache.rampart.RampartEngine.process(RampartEngine.java:144) After building source versions for Rampart (just 1.4 so far) I've traced this problem to the following source code: SAMUtil.java Element e = samlSubj.getKeyInfo(); X509Certificate[] certs = null; try { KeyInfo ki = new KeyInfo(e, null); if (ki.containsX509Data()) { X509Data data = ki.itemX509Data(0); XMLX509Certificate certElem = null; if (data != null && data.containsCertificate()) { certElem = data.itemCertificate(0); } if (certElem != null) { X509Certificate cert = certElem.getX509Certificate(); certs = new X509Certificate[1]; certs[0] = cert; return new SAMLKeyInfo(assertion, certs); } } The line ki.containsX509Data() above return false and fails. The value from the Element e is as follows: CN=Root Agency -147027885241304943914470421251724308948 JMYzUkmrT13JoYj2pGN5o/vxpGq8bKFXI1m18iEFu+5rF0wA4MYURGIEWE9/zg1apgjElQHus5qb4ZRCzg7IHyENCGq7um2w1SXxPzstoMsZ7oZ83Uq08lDdNV51QGzCCOdCi+YizKT7AJ1B6gaplxMnFEJ8TlnzFBCavMxSCho= The attempt to obtain the X509 data above is failing even when it appears in the message? (IssuerSerial). All references I've seen so far indicate that the style of X509 reference is supported by Rampart and WSS4J (default?!). This key reference is the certificate that ADFS2 has used to encrypt the message. Any help at all would be greatly appreciated! Thanks Jason
