• Root certificate authority works windows/linux but not mac osx - (malformed)

  - by AKwhat

  I have created a self-signed root certificate authority which if I install onto windows, linux, or even using the certificate store in firefox (windows/linux/macosx) will work perfectly with my terminating proxy. I have installed it into the system keychain and I have set the certificate to always trust. Within the chrome browser details it says "The certificate that Chrome received during this connection attempt is not formatted correctly, so Chrome cannot use it to protect your information. Error type: Malformed certificate" I used this code to create the certificate: openssl genrsa -des3 -passout pass:***** -out private/server.key 4096 openssl req -batch -passin pass:***** -new -x509 -nodes -sha1 -days 3600 -key private/server.key -out server.crt -config ../openssl.cnf If the issue is NOT that it is malformed (because it works everywhere else) then what else could it be? Am I installing it incorrectly? To be clear: Within the windows/linux OS, all browsers work perfectly. Within mac only firefox works if it uses its internal certificate store and not the keychain. It's the keychain method of importing a certificate that causes the issue. Thus, all browsers using the keychain will not work.

• Allowing connections initiated from outside

  - by Mark S. Rasmussen

  I've got an old Juniper SSG5 running ScreenOS 5.4.0r6.0. Once a day, more or less, it'll start randomly dropping packets at a rate of ~5-10%. We currently solve this issue by simply rebooting the unit, after which it resumes working in perfect condition. As this error has started appearing randomly, without any configuration or hardware changes, I'm assuming I've got an aging unit about to fail. As such, I've got a replacement SSG5 running ScreenOS 6.0. I've dumped the config on the 5.4 and imported it into a clean 6.0, and it seems to gladly accept it, and all my configuration seems to be A-OK. However, upon connecting the new unit, all outside-initiated connections seem to be blocked. If I browse our external IP from the inside, everything works perfectly, and it's not just port 80, SSH, Crashplan - all of our policies route correctly. All normal networking, initiated from the inside, work perfectly as well. If on the other hand I browse our external IP from the outside, everything is blocked. Barring differences between ScreenOS 5.4 and 6.0, the config is identical. Is there a setting somewhere that defines whether outside/inside initiated connections are allowed? unset key protection enable set clock timezone 1 set vrouter trust-vr sharable set vrouter

• More interruptions than cpu context switches

  - by Christopher Valles

  I have a machine running Debian GNU/Linux 5.0.8 (lenny) 8 cores and 12Gb of RAM. We have one core permanently around 40% ~ 60% wait time and trying to spot what is happening I realized that we have more interruptions than cpu context switches. I found that the normal ratio between context switch and interruptions is around 10x more context switching than interruptions but on my server the values are completely different. backend1:~# vmstat -s 12330788 K total memory 12221676 K used memory 3668624 K active memory 6121724 K inactive memory 109112 K free memory 3929400 K buffer memory 4095536 K swap cache 4194296 K total swap 7988 K used swap 4186308 K free swap 44547459 non-nice user cpu ticks 702408 nice user cpu ticks 13346333 system cpu ticks 1607583668 idle cpu ticks 374043393 IO-wait cpu ticks 4144149 IRQ cpu ticks 3994255 softirq cpu ticks 0 stolen cpu ticks 4445557114 pages paged in 2910596714 pages paged out 128642 pages swapped in 267400 pages swapped out 3519307319 interrupts 2464686911 CPU context switches 1306744317 boot time 11555115 forks Any ideas if that is an issue?

• rsync over ssh is not working anymore, while ssh itself is working fine (Write failed: broken pipe)

  - by brazorf

  This issue started happening after i changed router. This is the scenario: Windows7 Host Ubuntu 10.04 Guest (VirtualBox) Ubuntu 10.04 remote server What i used to do is run a very basic rsync command: rsync -avz --delete /local/path/ username@host:/path/to/remote/directory This worked perfect until i did change adsl provider, and i changed router aswell: now, this happens: rsync on Ubuntu Guest is not working anymore (to any random server), if using this new router rsync on Ubuntu Guest is WORKING, if i switch back to old router i tried a new virtual box ubuntu install, and the command is WORKING with both the routers So, the not-working-combo is oldUbuntu + newRouter. To get things worst, i can state that (on the not-working ubuntu) i ping the remote host plain ssh connection to the remote host is working fine (i can auth, connect, and do stuff on the remote host) scp is NOT working (this is just a further thing i tried) This is the console output of the execution, with ssh verbose set to vvvv: root@client:~# rsync -ae 'ssh -vvvv' /root/test-rsync/

• Unity3D draw call optimization : static batching VS manually draw mesh with MaterialPropertyBlock

  - by Heisenbug

  I've read Unity3D draw call batching documentation. I understood it, and I want to use it (or something similar) in order to optimize my application. My situation is the following: I'm drawing hundreds of 3d buildings. Each building can be represented using a Mesh (or a SubMesh for each building, but I don't thing this will affect performances) Each building can be textured with several combinations of texture patterns(walls, windows,..). Textures are stored into an Atlas for optimizaztion (see Texture2d.PackTextures) Texture mapping and facade pattern generation is done in fragment shader. The shader can be the same (except for few values) for all buildings, so I'd like to use a sharedMaterial in order to optimize parameters passed to the GPU. The main problem is that, even if I use an Atlas, share the material, and declare the objects as static to use static batching, there are few parameters(very fews, it could be just even a float I guess) that should be different for every draw call. I don't know exactly how to manage this situation using Unity3D. I'm trying 2 different solutions, none of them completely implemented. Solution 1 Build a GameObject for each building building (I don't like very much the overhead of a GameObject, anyway..) Prepare each GameObject to be static batched with StaticBatchingUtility.Combine. Pack all texture into an atlas Assign the parent game object of combined batched objects the Material (basically the shader and the atlas) Change some properties in the material before drawing an Object The problem is the point 5. Let's say I have to assign a different id to an object before drawing it, how can I do this? If I use a different material for each object I can't benefit of static batching. If I use a sharedMaterial and I modify a material property, all GameObjects will reference the same modified variable Solution 2 Build a Mesh for every building (sounds better, no GameObject overhead) Pack all textures into an Atlas Draw each mesh manually using Graphics.DrawMesh Customize each DrawMesh call using a MaterialPropertyBlock This would solve the issue related to slightly modify material properties for each draw call, but the documentation isn't clear on the following point: Does several consecutive calls to Graphic.DrawMesh with a different MaterialPropertyBlock would cause a new material to be instanced? Or Unity can understand that I'm modifying just few parameters while using the same material and is able to optimize that (in such a way that the big atlas is passed just once to the GPU)?

• SQL SERVER – Fix : Error 3623 – An invalid floating point operation occurred

  - by pinaldave

  Going back in time, I always had a problem with mathematics. It was a great subject and I loved it a lot but I only mastered it after practices a lot. I learned that mathematics problems should be addressed systematically and being verbose is not a trick, I learned to solve any problem. Recently one of reader sent me an email with the title “Mathematics problem – please help!” and I was a bit scared. I was good at mathematics but not the best. When I opened the email I was relieved as it was Mathematics problem with SQL Server. My friend received following error while working with SQL Server. Msg 3623, Level 16, State 1, Line 1 An invalid floating point operation occurred. The reasons for the error is simply that invalid usage of the mathematical function is attempted. Let me give you a few examples of the same. SELECT SQRT(-5); SELECT ACOS(-3); SELECT LOG(-9); If you run any of the above functions they will give you an error related to invalid floating point. Honestly there is no workaround except passing the function appropriate values. SQRT of a negative number will give you result in real numbers which is not supported at this point of time as well LOG of a negative number is not possible (because logarithm is the inverse function of an exponential function and the exponential function is NEVER negative). When I send above reply to my friend he did understand that he was passing incorrect value to the function. As mentioned earlier the only way to fix this issue is finding incorrect value and avoid passing it to the function. Every mathematics function is different and there is not a single solution to identify erroneous value passed. If you are facing this error and not able to figure out the solution. Post a comment and I will do my best to figure out the solution.

  I was running 11.10 and decided to do the full upgrade and come up to 12.04 after the update SSH (not SSHD) is now misbehaving when attempting to connect to other OpenSSH instances. I say OpenSSH as I am running a DropBear sshd on my router and I am able to connect to it. When attempting to connect to an OpenSSH server risk@skynet:~/.ssh$ ssh -vvv risk@someserver OpenSSH_5.9p1 Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012 debug1: Reading configuration data /home/risk/.ssh/config debug3: key names ok: [[email protected],[email protected],[email protected],[email protected],ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,ssh-rsa,ssh-dss] debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to someserver [someserver] port 22. debug1: Connection established. debug1: identity file /home/risk/.ssh/id_rsa type -1 debug1: identity file /home/risk/.ssh/id_rsa-cert type -1 debug1: identity file /home/risk/.ssh/id_dsa type -1 debug1: identity file /home/risk/.ssh/id_dsa-cert type -1 debug3: Incorrect RSA1 identifier debug3: Could not load "/home/risk/.ssh/id_ecdsa" as a RSA1 public key debug1: identity file /home/risk/.ssh/id_ecdsa type 3 debug1: Checking blacklist file /usr/share/ssh/blacklist.ECDSA-521 debug1: Checking blacklist file /etc/ssh/blacklist.ECDSA-521 debug1: identity file /home/risk/.ssh/id_ecdsa-cert type -1 ssh_exchange_identification: read: Connection reset by peer risk@skynet:~/.ssh$ DropBear instance risk@skynet:~/.ssh$ ssh -vvv root@darkness OpenSSH_5.9p1 Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012 debug1: Reading configuration data /home/risk/.ssh/config debug3: key names ok: [[email protected],[email protected],[email protected],[email protected],ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,ssh-rsa,ssh-dss] debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to darkness [192.168.1.1] port 22. debug1: Connection established. debug1: identity file /home/risk/.ssh/id_rsa type -1 debug1: identity file /home/risk/.ssh/id_rsa-cert type -1 debug1: identity file /home/risk/.ssh/id_dsa type -1 debug1: identity file /home/risk/.ssh/id_dsa-cert type -1 debug3: Incorrect RSA1 identifier debug3: Could not load "/home/risk/.ssh/id_ecdsa" as a RSA1 public key debug1: identity file /home/risk/.ssh/id_ecdsa type 3 debug1: Checking blacklist file /usr/share/ssh/blacklist.ECDSA-521 debug1: Checking blacklist file /etc/ssh/blacklist.ECDSA-521 debug1: identity file /home/risk/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 2.0, remote software version dropbear_0.52 debug1: no match: dropbear_0.52 ...

• SQL SERVER – Mirroring Configured Without Domain – The server network address TCP://SQLServerName:50

  - by pinaldave

  Regular readers of my blog will be aware of my friend who called me few days ago with very a funny SQL Problem SQL SERVER – SSMS Query Command(s) completed successfully without ANY Results. This time, it did not take long before he called me up with another interesting problem, although the issue he was facing this time was not that interesting and also very specific to him, however, he insisted me to share with all of you. Let us understand his situation at first. My friend is preparing for DBA exam Exam 70-450: PRO: Designing, Optimizing and Maintaining a Database Server Infrastructure using Microsoft SQL Server 2008 and for the same, he was trying to set up replication on his local laptop. He had installed two different instances of SQL Server on his computer and every time when he started the mirroring, it failed with common error message. The server network address “TCP://SQLServer:5023? cannot be reached or does not exist. Check the network address name and that the ports for the local and remote endpoints are operational. (Microsoft SQL Server, Error: 1418) Well, before he contacted me, he searched online and checked my article written on the error in mirroring. However, he tried all the four suggestions, but it did not solve his problem. He called me at a reasonable time of late evening (unlike last time, which was midnight!). I even tried all the seven different suggestions myself, as previously proposed in my article; however, none of them worked. While looking at closely at services, I noticed something very simple. He was running all the instances on ‘Network Services’. In fact, his computer was a stand-alone computer. There was no network at all. Also, there was no domain or any other advance network concepts implemented. I just changed services from ‘Network Services’ to ‘Local System’ as his SQL Server was running on his local system and there were no network services. This prompted to restart the services. As this was not the production server and his development machine, we restarted the services on the laptop (do not restart services on production server without proper planning). After changing the ‘services log on’ account to localsystem, when he attempted to reconfigure the mirroring it worked right away. As usually in production server, proper domains are configured and advance network concepts are implemented I had never faced this type of problem earlier. My friend insisted to post this solution to his situation, wherein there was no domain configured and setting up mirroring was throwing an error. According to him, this is bound to help people, like him, who are preparing for certification using single system.

• Using DEBUG Mode in Oracle SQL Developer to Log SQL

  - by thatjeffsmith

  Curious how we’re getting the data you see in SQL Developer when you click on something? While many of the dialogs provide a ‘SQL’ panel that shows you the SQL ABOUT to be generated, I’d rather see the SQL AS it’s executed. True, you could set a TRACE or fire up a Monitor Sessions report, but both of those solutions leave me hungry for more. Did you know that SQL Developer has a ‘debug’ mode? It slows the tool down a bit and spits out a lot of information you don’t care about, but it ALSO shows you ALL the SQL that is sent to the database, as you click around the tool! See ALL the SQL that SQL Developer sends to the database on your behalf Enable DEBUG Mode When you see the splash screen as SQL Developer fires up, frantically hit Up, Up, Down, Down, Left, Right, Left, Right, B, A, SELECT, Start. Wait, wrong game. No, all you need to do is go to your SQL Developer directory and navigate down to the ‘bin’ directory. In that directory, find the ‘sqldeveloper.conf’ file. Install Directory - sqldeveloper - bin - sqldeveloper.conf Open it with a text editor. Find this line IncludeConfFile sqldeveloper-nondebug.conf And replace it with this line IncludeConfFile sqldeveloper-debug.conf Save the file. Start up SQL Developer. Observe the Logging Page – Log Panel for the SQL There’s going to be more than just SQL here. You’ll actually see a LOT of other information. If you’re having general problems with the tool and you want to see the nitty-gritty of what’s going on, then this is a good place to satisfy your curiosity and might help us diagnose your issue if you post to the forums or open a ticket with My Oracle Support. You’ll find ‘INFO’ entries that look a little something like this - This is the query used to populate your Tables list in the connection tree. You can double-click on the sql text and get a pop-up window that’s much easier to read. See all that typing we’re saving you? I don’t recommend running in DEBUG mode all the time. Capturing this information and displaying it is more expensive than not doing so. And it provides a lot of information you don’t normally need to see. But when you DO want to know what’s going on and why, this is an excellent way of getting that information. When you’re ready to go back to ‘normal’ mode, just close SQL Developer, go back to your .conf file, and add the ‘nondebug’ bit back.

• Microsoft, please help me diagnose TFS Administration permission issues!

  - by Martin Hinshelwood

  I recently had a fun time trying to debug a permission issue I ran into using TFS 2010’s TfsConfig. Update 5th March 2010 – In its style of true excellence my company has added rant to its “Suggestions for Better TFS”. <rant> I was trying to run the TfsConfig tool and I kept getting the message: “TF55038: You don't have sufficient privileges to run this tool. Contact your Team Foundation system administrator." This message made me think that it was something to do with the Install permissions as it is always recommended to use a single account to do every install of TFS. I did not install the original TFS on our network and my account was not used to do the TFS2010 install. But I did do the upgrade from 2010 beta 2 to 2010 RC with my current account. So I proceeded to do some checking: Am I in the administrators group on the server? Figure: Yes, I am in the administrators group on the server Am I in the Administration Console users list? Figure: Yes, I am in the Administration Console users list Have I reapplied the permissions in the Administration Console users list ticking all the options? Figure: Make sure you check all of the boxed if you want to have all the admin options Figure: Yes, I have made sure that all my options are correct. Am I in the Team Foundation administrators group? Figure: Yes, I am in the Team Foundation Administrators group Is my account explicitly SysAdmin on the Database server? Figure: Yes, I do have explicit SysAdmin on the database Can you guess what the problem was? The command line window was not running as the administrator! As with most other applications there should be an explicit error message that states: "You are not currently running in administrator mode; please restart the command line with elevated privileges!" This would have saved me 30 minutes, although I agree that I should change my name to Muppet and just be done with it. </rant>   Technorati Tags: Visual Studio ALM,Administration,Team Foundation Server Admin Console,TFS Admin Console

• Why do apache2 upgrades remove and not re-install libapache2-mod-php5?

  - by nutznboltz

  We repeatedly see that when an apache2 update arrives and is installed it causes the libapache2-mod-php5 package to be removed and does not subsequently re-install it automatically. We must subsequently re-install the libapache2-mod-php5 manually in order to restore functionality to our web server. Please see the following github gist, it is a contiguous section of our server's dpkg.log showing the November 14, 2011 update to apache2: https://gist.github.com/1368361 it includes 2011-11-14 11:22:18 remove libapache2-mod-php5 5.3.2-1ubuntu4.10 5.3.2-1ubuntu4.10 Is this a known issue? Do other people see this too? I could not find any launchpad bug reports about it. Platform details: $ lsb_release -ds Ubuntu 10.04.3 LTS $ uname -srvm Linux 2.6.38-12-virtual #51~lucid1-Ubuntu SMP Thu Sep 29 20:27:50 UTC 2011 x86_64 $ dpkg -l | awk '/ii.*apache/ {print $2 " " $3 }' apache2 2.2.14-5ubuntu8.7 apache2-mpm-prefork 2.2.14-5ubuntu8.7 apache2-utils 2.2.14-5ubuntu8.7 apache2.2-bin 2.2.14-5ubuntu8.7 apache2.2-common 2.2.14-5ubuntu8.7 libapache2-mod-authnz-external 3.2.4-2+squeeze1build0.10.04.1 libapache2-mod-php5 5.3.2-1ubuntu4.10 Thanks At a high-level the update process looks like: package package_name do action :upgrade case node[:platform] when 'centos', 'redhat', 'scientific' options '--disableplugin=fastestmirror' when 'ubuntu' options '-o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold"' end end But at a lower level def install_package(name, version) run_command_with_systems_locale( :command = "apt-get -q -y#{expand_options(@new_resource.options)} install #{name}=#{version}", :environment = { "DEBIAN_FRONTEND" = "noninteractive" } ) end def upgrade_package(name, version) install_package(name, version) end So Chef is using "install" to do "update". This sort of moves the question around to "how does apt-get safe-upgrade" remember to re-install libapache-mod-php5? The exact sequence of packages that triggered this was: apache2 apache2-mpm-prefork apache2-mpm-worker apache2-utils apache2.2-bin apache2.2-common But the code is attempting to run checks to make sure the packages in that list are installed already before attempting to "upgrade" them. case node[:platform] when 'debian', 'centos', 'fedora', 'redhat', 'scientific', 'ubuntu' # first primitive way is to define the updates in the recipe # data bags will be used later %w/ apache2 apache2-mpm-prefork apache2-mpm-worker apache2-utils apache2.2-bin apache2.2-common /.each{ |package_name| Chef::Log.debug("is #{package_name} among local packages available for changes?") next unless node[:packages][:changes].keys.include?(package_name) Chef::Log.debug("is #{package_name} available for upgrade?") next unless node[:packages][:changes][package_name][:action] == 'upgrade' package package_name do action :upgrade case node[:platform] when 'centos', 'redhat', 'scientific' options '--disableplugin=fastestmirror' when 'ubuntu' options '-o Dpkg::Options::="--force-confdef" -o Dpkg::Options::="--force-confold"' end end tag('upgraded') } # after upgrading everything, run yum cache updater if tagged?('upgraded') # Remove old orphaned dependencies and kernel images and kernel headers etc. # Remove cached deb files. case node[:platform] when 'ubuntu' execute 'apt-get -y autoremove' execute 'apt-get clean' # Re-check what updates are available soon. when 'centos', 'fedora', 'redhat', 'scientific' node[:packages][:last_time_we_looked_at_yum] = 0 end untag('upgraded') end end But it's clear that it fails since the dpkg.log has 2011-11-14 11:22:25 install apache2-mpm-worker 2.2.14-5ubuntu8.7 on a system which does not currently have apache2-mpm-worker. I will have to discuss this with the author, thanks again.

• Getting started with Blocks and namespaces - Enterprise Library 5.0 Tutorial Part 2

  This is my second post in this series. In first blog post I explained how to install Enterprise Library 5.0 and provided links to various resources. Enterprise Library is divided into various blocks. Simply we can say, a block is a ready made solution for a particular common problem across various applications. So instead focusing on implementation of common problem across various applications, we can reuse these fully tested and extendable blocks to increase the productivity and also extendibility as these blocks are made with good design principles and patterns. Major blocks of Enterprise Library 5.0 are as follows.   Core infrastructure Functional Application Blocks Caching Data Exception Handling Logging Security Cryptography Validation Wiring Application Blocks Unity Policy Injection/Interception   Each block resides in its own assembly, and also some extra assemblies for common infrastructure. Assemblies are as follows. Microsoft.Practices.EnterpriseLibrary.Caching.Cryptography.dll Microsoft.Practices.EnterpriseLibrary.Caching.Database.dll Microsoft.Practices.EnterpriseLibrary.Caching.dll Microsoft.Practices.EnterpriseLibrary.Common.dll Microsoft.Practices.EnterpriseLibrary.Configuration.Design.HostAdapter.dll Microsoft.Practices.EnterpriseLibrary.Configuration.Design.HostAdapterV5.dll Microsoft.Practices.EnterpriseLibrary.Configuration.DesignTime.dll Microsoft.Practices.EnterpriseLibrary.Configuration.EnvironmentalOverrides.dll Microsoft.Practices.EnterpriseLibrary.Data.dll Microsoft.Practices.EnterpriseLibrary.Data.SqlCe.dll Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.dll Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.Logging.dll Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.WCF.dll Microsoft.Practices.EnterpriseLibrary.Logging.Database.dll Microsoft.Practices.EnterpriseLibrary.Logging.dll Microsoft.Practices.EnterpriseLibrary.PolicyInjection.dll Microsoft.Practices.EnterpriseLibrary.Security.Cache.CachingStore.dll Microsoft.Practices.EnterpriseLibrary.Security.Cryptography.dll Microsoft.Practices.EnterpriseLibrary.Security.dll Microsoft.Practices.EnterpriseLibrary.Validation.dll Microsoft.Practices.EnterpriseLibrary.Validation.Integration.AspNet.dll Microsoft.Practices.EnterpriseLibrary.Validation.Integration.WCF.dll Microsoft.Practices.EnterpriseLibrary.Validation.Integration.WinForms.dll Microsoft.Practices.ServiceLocation.dll Microsoft.Practices.Unity.Configuration.dll Microsoft.Practices.Unity.dll Microsoft.Practices.Unity.Interception.dll Enterprise Library Configuration Tool In addition to these assemblies you would get configuration tool “EntLibConfig-32.exe”. If you are targeting your application to .NET 4.0 framework then you would need to use “EntLibConfig.NET4.exe”. Optionally you can install Visual Studio 2008 and Visual Studio 2010 add-ins whilst installing of Enterprise Library. So that you can invoke the enterprise Library configuration from Visual Studio by right clicking on “app.config” or “web.config” file as shown below. I would suggest you to download the documentation from Codeplex which was released on May 2010. It consists 3MB of information. you can also find issue tracker to know various issues/bugs currently people talking about enterprise library. There is also discussion link takes you to community site where you can post your questions. In my next blog post, I would cover more on each block. span.fullpost {display:none;}

• Force.com presents Database.com SQL Azure/Amazon RDS unfazed

  - by Sarang

  At the DreamForce 2010 event in San Francisco Force.com unveiled their next big thing in the Fat SaaS portfolio "Database.com".  I am still wondering how would they would've shelled out for that domain name. Now why would a already established SaaS player foray into a key building block like Database? Potentially allowing enterprises to build apps that do not utilize the Force.com stack! One key reason is being seen as the Fat SaaS player with evey trick in the SaaS space under his belt. You want CRM come hither, want a custom development PaaS like solution welcome home (VMForce), want all your apps to talk to a cloud DB and minimize latency by having it reside closer to you cloud apps? You've come to the right place sire! Other is potentially killing foray of smaller DB players like Oracle (Not surprisingly, the Database.com offering is a highly customized and scalable Oracle database) from entering the lucrative SaaS db marketplace. The feature set promised looks great out of the box for someone who likes to visualize cool new architectures. The ground realities are certainly going to be a lot different considering the SOAP/REST style access patterns in lieu of the comfortable old shoe of SQL. Microsoft suffered heavily with SDS (SQL Data Services) offering in early 2009 and had to pull the plug on the product only to reintroduce as a simple SQL Server in the cloud, SQL Windows Azure. Though MSFT is playing cool by providing OData semantics to work with SQL Windows Azure satisfying atleast some needs of the Web-Style to a DB. The other features like Social data models including Profiles, Status updates, feeds seem interesting as well. (Although I beleive social is just one of the aspects of large scale collaborative computing). All these features start "Free" for devs its a good news but the good news stops here. The overall pricing model of $ per Users per Transactions / Month is highly disproportionate compared to Amazon RDS (Based on MySQL) or SQL Windows Azure (Based on MSSQL). Roger Jennigs of Oakleaf did an interesting comparo based on 3, 10, 100, 500 users and it turns out that Database.com going by current understanding is way too expensive for the services on offer. The offering may not impact the decision for DotNet shops mulling their cloud stategy or even some Java/MySQL shops thinking about Amazon RDS, however for enterprises having already invested in other force.com offerings this could be a very important piece in the cloud strategy jigsaw. One which would address a key cloud DB issue of "Latency" for them at least it will help having the DB in the neighborhood. The tooling and "SQL like" access provider drivers (Think ODBC/JDBC) will be available later this year. Progress Software has already announced their JDBC driver stack for Database.com. It remains to be seen how effective the overall solutions proves to be in the longer run but for starts its a important decision towards consolidating Force.com's already strong positioning in the SaaS space. As always contrasting views are welcome! :)

• SQL SERVER – FT_IFTS_SCHEDULER_IDLE_WAIT – Full Text – Wait Type – Day 13 of 28

  - by pinaldave

  In the last few days during this series, I got many question about this Wait type. It would be great if you read my original related wait stats query in the first post because I have filtered it out in WHERE clause. However, I still get questions about this being one of the most wait types they encounter. The truth is, this is a background task processing and it really does not matter and it should be filtered out. There are many new Wait types related to Full Text Search that are introduced in SQL Server 2008. If you run the following query, you will be able to find them in the list. Currently there is not enough information for all of them available on BOL or any other place. But don’t worry; I will write an in-depth article when I learn more about them. SELECT * FROM sys.dm_os_wait_stats WHERE wait_type LIKE 'FT_%' The result set will contain following rows. FT_RESTART_CRAWL FT_METADATA_MUTEX FT_IFTSHC_MUTEX FT_IFTSISM_MUTEX FT_IFTS_RWLOCK FT_COMPROWSET_RWLOCK FT_MASTER_MERGE FT_IFTS_SCHEDULER_IDLE_WAIT We have understood so far that there is not much information available. But the problem is when you have this Wait type, what should you do?  The answer is to filter them out for the moment (i.e, do not pay attention on them) and focus on other pressing issues in wait stats or performance tuning. Here are two of my informal suggestions, which are totally independent from wait stats: Turn off the Full Text Search service in your system if you are  not necessarily using it on your server. Learn proper Full Text Search methodology. You can get Michael Coles’ book: Pro Full-Text Search in SQL Server 2008. Now I invite you to speak out your suggestions or any input regarding Full Text-related best practices and wait stats issue. Please leave a comment. Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All the discussions of Wait Stats in this blog are generic and vary from system to system. It is recommended that you test this on a development server before implementing it to a production server.

• Resolving IIS7 HTTP Error 500.19 - Internal Server Error

  - by fatherjack

  LiveJournal Tags: RedGate Tools,SQL Server,Tips and Tricks How To The requested page cannot be accessed because the related configuration data for the page is invalid. As part of my work recently I was moving SQL Monitor from the bespoke XSP web server to be hosted on IIS instead. This didn't go smoothly. I was lucky to be helped by Red Gate's support team (http://twitter.com/kickasssupport). I had SQL Monitor installed and working fine on the XSP site but wanted to move to IIS so I reinstalled the software and chose the IIS option. This wasn't possible as IIS wasn't installed on the server. I went to Control Panel, Windows features and installed IIS and then returned to the SQL Monitor installer. Everything went as planned but when I browsed the site I got a huge error with the message "HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid." All links that I could find suggested it was a permissions issue, based on the directory where the config file was stored. I changed this any number of times and also tried the altering its location. Nothing resolved the error. It was only when I was trying the installation again that I read through the details from Red Gate and noted that they referred to ASP settings that I didn't have. Essentially I was seeing this. I had installed IIS using the default settings and that DOESN'T include ASP. When this dawned on me I went back through the windows components installation process and ticked the ASP service within the IIS role. Completing this and going back to the IIS management console I saw something like this; so many more options! When I clicked on the Authentication icon this time I got the option to not only enable Anonymous Authentication but also ASP.NET Impersonation (which is disabled by default). Once I had enabled this the SQL Monitor website worked without error. I think the HTTP Error 500.19 is misleading in this case and at the very least should be able to recognise if the ASP service is installed or not and then to include a hint that it should be. I hope this helps some people and avoids wasting as much of your time as it did mine. Let me know if it helps you.

• Blender mesh mirroring screws up normals when importing in Unity

  - by Shivan Dragon

  My issue is as follows: I've modeled a robot in Blender 2.6. It's a mech-like biped or if you prefer, it kindda looks like a chicken. Since it's symmetrical on the XZ plane, I've decided to mirror some of its parts instead of re-modeling them. Problem is, those mirrored meshes look fine in Blender (faces all show up properly and light falls on them as it should) but in Unity faces and lighting on those very same mirrored meshes is wrong. What also stumps me is the fact that even if I flip normals in Blender, I still get bad results in Unity for those meshes (though now I get different bad results than before). Here's the details: Here's a Blender screen shot of the robot. I've took 2 pictures and slightly rotated the camera around so the geometry in question can be clearly seen: Now, the selected cog-wheel-like piece is the mirrored mesh obtained from mirroring the other cog-wheel on the other (far) side of the robot torso. The back-face culling is turned of here, so it's actually showing the faces as dictated by their normals. As you can see it looks ok, faces are orientated correctly and light falls on it ok (as it does on the original cog-wheel from which it was mirrored). Now if I export this as fbx using the following settings: and then import it into Unity, it looks all screwy: It looks like the normals are in the wrong direction. This is already very strange, because, while in Blender, the original cog-wheel and its mirrored counter part both had normals facing one way, when importing this in Unity, the original cog-wheel still looks ok (like in Blender) but the mirrored one now has normals inverted. First thing I've tried is to go "ok, so I'll flip normals in Blender for the mirrored cog-wheel and then it'll display ok in Unity and that's that". So I went back to Blender, flipped the normals on that mesh, so now it looks bad in Blender: and then re-exported as fbx with the same settings as before, and re-imported into Unity. Sure enough the cog-wheel now looks ok in Unity, in the sense where the faces show up properly, but if you look closely you'll notice that light and shadows are now wrong: Now in Unity, even though the light comes from the back of the robot, the cog-wheel in question acts as if light was coming from some-where else, its faces which should be in shadow are lit up, and those that should be lit up are dark. Here's some things I've tried and which didn't do anything: in Blender I tried mirroring the mesh in 2 ways: first by using the scale to -1 trick, then by using the mirroring tool (select mesh, hit crtl-m, select mirror axis), both ways yield the exact same result in Unity I've tried playing around with the prefab import settings like "normals: import/calculate", "tangents: import/calculate" I've also tired not exporting as fbx manually from Blender, but just dropping the .blend file in the assets folder inside the Unity project So, my question is: is there a way to actually mirror a mesh in Blender and then have it imported in Unity so that it displays properly (as it does in Blender)? If yes, how? Thank you, and please excuse the TL;DR style.

• SQL SERVER – 4 Tips for ETL Software IDE Developers

  - by pinaldave

  In a previous blog, I introduced the notion of Semantic Types. To an end-user, a seamlessly integrated semantic typing engine significantly increases the ease of use of an ETL IDE (integrated development environment, or developer studio). This led me to think about other ease-of-use issues I have encountered while building ETL applications. When I get stumped while programming, I find myself asking the variations on these questions: “How do I…?” “Now what?” “Why isn’t this working?” “Why do I have to redo the work I just did?” It seems to me that a good ETL IDE will anticipate these questions and seek to answer them before they are even asked. So here are my tips to help software vendors build developer IDEs that actually make development easier. How do I…? While developing an ETL application, have you ever asked yourself: “How do I set up the connection to my SQL Server database?”,“How do I import my table definitions from Access?”, etc. An easy answer might be “read the manual” but sometimes product manuals are not robust or easily accessible. So, integrating robust how-to instructions directly into your ETLstudio would help users get the information they need at the time they need it. Now what? IDEs in general know where you last clicked or performed an action using an input device such as a keyboard; so they should be able to reasonably predict the design context you are in and suggest the next steps accordingly. Context-sensitive suggestions based on the state of the user’s work will help users move forward in ETL application development. Why isn’t this working? Or why do I have to wait till I compile to be told about a critical design issue? If an ETL IDE is smart enough to signal to users what in their design structures is left to be completed or has been completed incorrectly, then the developer can spend much less time in the designàcompileàerror-correct loop. Just-in-time validation helps users detect and correct programming errors earlier in the ETL development life cycle. Why do I have to redo the work I just did? In ETL development, schemas, transformation rules, connectivity objects, etc., can be reused in various situations. Using mouse-clicks to build and manage libraries of reusable design objects implies that the application development effort should decrease over time and as the library acquires more objects. I met a great company at SQL Pass that is trying to address many of these usability issues. Check them out at www.expressor-software.com. What other ease-of-use suggestions do you have for ETL software vendors? Please post your valuable comments. ?Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Best Practices, Pinal Dave, PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology Tagged: ETL

• [SQLServer JDBC Driver][SQLServer]Could not find stored procedure 'master..xp_jdbc_open2'.

  - by Vijaya Moderator -Oracle

  When connecting to MS SQL Server Database via Weblogic Datasource and using XA jdbc driver, the following error is thrown. <Jun 3, 2014 5:16:49 AM PDT> <Error> <Console> <BEA-240003> <Console encountered the following error java.sql.SQLException: [FMWGEN][SQLServer JDBC Driver][SQLServer]Could not find stored procedure 'master..xp_jdbc_open2'. at weblogic.jdbc.sqlserverbase.ddb_.b(Unknown Source)at weblogic.jdbc.sqlserverbase.ddb_.a(Unknown Source)at weblogic.jdbc.sqlserverbase.ddb9.b(Unknown Source)at weblogic.jdbc.sqlserverbase.ddb9.a(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddr.v(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddr.a(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddq.a(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddr.a(Unknown Source)at weblogic.jdbc.sqlserver.ddj.m(Unknown Source)at weblogic.jdbc.sqlserverbase.ddel.e(Unknown Source)at weblogic.jdbc.sqlserverbase.ddel.a(Unknown Source)  The cause behind the issue is that  the MS SQL Server was not installed with the Stored procedures to enable JTA/XA Solution To connect to SQL Server via XA Driver from WLS Datasource you need to install Stored Procedures for JTATo use JDBC distributed transactions through JTA, your system administrator should use the following procedure to install Microsoft SQL Server JDBC XA procedures. This procedure must be repeated for each MS SQL Server installation that will be involved in a distributed transaction.To install stored procedures for JTA:1. Copy the appropriate sqljdbc.dll and instjdbc.sql files from the WL_HOME\server\lib directory to the SQL_Server_Root/bin directory of the MS SQL Server database server, where WL_HOME is the directory in which WebLogic server is installed, typically c:\Oracle\Middleware\wlserver_10.x.  Note:  If you are installing stored procedures on a database server with multiple Microsoft SQL Server instances, each running SQL Server instance must be able to locate the sqljdbc.dll file.Therefore the sqljdbc.dll file needs to be anywhere on the global PATH or on the application-specific path. For the application-specific path, place the sqljdbc.dll file into the :\Program Files\Microsoft SQL Server\MSSQL$\Binn directory for each instance. 2. From the database server, use the ISQL utility to run the instjdbc.sql script. As a precaution, have your system administrator back up the master database before running instjdbc.sql. At a command prompt, use the following syntax to run instjdbc.sql:  ISQL -Usa -Psa_password -Sserver_name -ilocation\instjdbc.sql  where:  sa_password is the password of the system administrator.  server_name is the name of the server on which SQL Server resides.  location is the full path to instjdbc.sql. (You copied this script to the SQL_Server_Root/bin directory in step 1.)  The instjdbc.sql script generates many messages. In general, these messages can be ignored; however, the system administrator should scan the output for any messages that may indicate an execution error. The last message should indicate that instjdbc.sql ran successfully. The script fails when there is insufficient space available in the master database to store the JDBC XA procedures or to log changes to existing procedures.

• Agile isn’t always Agile

  - by BuckWoody

  I want to make a disclaimer before I dive into this topic – At Microsoft we use all kinds of development methodologies, and I’ve worked in lots of other shops using lots of methodologies. This is one of those “religious” topics like which programming language or database is best, and is bound to generate some heat. But this isn’t pointed towards one particular event or company. But I really don’t like Agile. In particular, I really don’t like Scrum. Let me explain. Agile is a methodology for developing software that emphasizes adapting to change more so than the traditional “waterfall” method of developing software. Within Agile is a process called a “scrum” meeting. The pitch goes that in this quick, stand-up meeting the people involved in the development project (which should include the DBA, but very often doesn’t) go around the room stating what they are working on, when that will be finished and what is keeping them from getting finished (“blockers”, these are called). Sounds all very non-threatening – we’re just “enabling” the developers to work more efficiently. And that’s what we all want, isn’t it? Except it doesn’t work. In my experience (and yours might be VERY different) this just turns into a micro-management environment, where devs have to defend their daily work. Of all the work environments I hate the most, micro-management environments are THE worst. I don’t like workign in them, and I don’t like creating them. The other issue I have with Scrum is that it makes your whole team task-focused. Everyone wants to make sure that they are not the “long pole” in the meeting (meaning that they aren’t the one that gets all the attention) so they only focus on safe, quick tasks. And although you have all of the boxes checked, the project does not go well at all – even when it does finish. Before you comment (and please do comment) I fully realize that Agile <> Scrum. But in my experience, it sometimes turns into that. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Cocos2d-x Spritebatch node animation appears to be broken? cocos2d-x 2.0.3

  - by George Host

  Hi I have spent aprox 2 days trying to get this to work doing a google searches left and right and I did get it working except for sprite batch nodes. So in my class I am able to load kuwalio_stand.png and I tested kuwalio_walk1.png and 2 and 3 from the FrameCache(). They work for sure 100%. I run this code and it does not animate does anyone else have the same issue with sprite batch nodes? cocos2d::CCSprite * player = Player::create(); player->setPosition(cocos2d::CCPointMake(0.0f,0.0f)); player->setDisplayFrame(cocos2d::CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("kuwalio_stand.png")); player->setTag(PlayerTag); cocos2d::CCAnimation * walk = cocos2d::CCAnimation::create(); cocos2d::CCSpriteFrame * walk1 = cocos2d::CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("kuwalio_walk1"); cocos2d::CCSpriteFrame * walk2 = cocos2d::CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("kuwalio_walk2"); cocos2d::CCSpriteFrame * walk3 = cocos2d::CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName("kuwalio_walk3"); walk->addSpriteFrame(walk1); walk->addSpriteFrame(walk2); walk->addSpriteFrame(walk3); cocos2d::CCAnimate * actionWalk = cocos2d::CCAnimate::create(walk); cocos2d::CCRepeatForever * actionRepeat = cocos2d::CCRepeatForever::create(actionWalk); walk->setDelayPerUnit(0.1f); actionWalk->setDuration(10.1f); this->runAction(actionRepeat); // Change camera to a soft follow camera. this->runAction(cocos2d::CCFollow::create(player)); mSceneSpriteBatchNode->addChild(player); // Have the CCNode object run its virtual update function as fast as possible. // Every frame for this layer. this-scheduleUpdate(); Counter example without the sprite batch node... cocos2d::CCSprite * sprite = cocos2d::CCSprite::create("kuwalio_walk1.png"); this->addChild(sprite,0); sprite->setPosition(cocos2d::CCPointMake(60,60)); sprite->retain(); cocos2d::CCAnimation * actionAnimation = cocos2d::CCAnimation::create(); actionAnimation->setDelayPerUnit(0.01f); actionAnimation->retain(); actionAnimation->addSpriteFrameWithFileName("kuwalio_walk1.png"); actionAnimation->addSpriteFrameWithFileName("kuwalio_walk2.png"); actionAnimation->addSpriteFrameWithFileName("kuwalio_walk3.png"); cocos2d::CCAnimate * a = cocos2d::CCAnimate::create(actionAnimation); a->setDuration(0.10f); cocos2d::CCRepeatForever * actionRepeat = cocos2d::CCRepeatForever::create(a); sprite->runAction(actionRepeat);

• Resources such as libraries, engines and frameworks to make Javacript-based MMORTS? [closed]

  - by hhh

  I am looking for resources outlined to make a MMORTS with Javascript as the client-side, probably just a simple canvas for the frontend. The guy in the video here mentions that JavaScript is one of the most misunderstood language -- and I do believe that. I think one can make quite cool games with it in the future. So I am now proactively looking for resources and perhaps some ideas. My first idea contained Node.js, C and NetBSD/bozohttpd (or the-4-7-chars' *ix-thing with green-logo -thing, move the q here) but I acknowledge my beginner -style approach -- this issue is broad and not only for one person to make it all-the-time-improved project! So I think perfect for community to tinker. Some games and examples possibly easy to make into MMORTS BrowserQuest here under MPL 2.0 and its content licensed under CC-BY-SA 3.0 (source here) [proprietary] LoU here and built with JS/Qooxdoo/c#/Windows-Server/ISS/etc, source. MY ANSWER BEGINS HERE TO BE MOVED BELOW, REQUIRING RE-OPENING. PLEASE, VOTE TO OPEN IT -- HELP US TO TINKER! My answer Generic Is there an MMO-related research body? Although about Android, certain things also appropriate with JS -game: Are there any 2D gaming libraries/frameworks/engines for Android? Why is it so hard to develop a MMO? Browser based MMO Architecture MMO architecture - Highly Scalable with Reporting capabilities What are the Elements of an MMO Game? Is this the right architecture for our MMORPG mobile game? Looking for architectures to develop massive multiplayer game server Information on seamless MMO server architecture Game-mechanics (search) Question sounding like about LoU: What are the different ways to balance an online multiplayer game where user spend different amounts of time online? Building an instance system What are the different ways to balance an online multiplayer game where user spend different amounts of time online? Hosting is it possible to make a MMO starting with scalable hosting? Should I keep login server apart from game server? MMO techniques, algorithms and resources for keeping bandwidth low?

How to update the monsters in my MMO server using Node.js and Socket.IO Are there any good html 5 mmo design tutorials? Networking Loadbalancing Questions Something about TCP, routers, NAT, etc: How do I start writing an MMO game server? Who does the AI calculations in an MMO?
