  • Broken cups installation on a ubuntu server 64

    - by user67046
    Hi, I am having trouble with an cups installation. It seems to be in a broken state. When i try to reinstall it it stalls, the same if i try to remove it completely. I am running the server version 64 bit of Ubuntu 10.10 with kernel Linux version 2.6.35-22-server. When i try to start the cups daemon with the following command sudo service cups start It just stays there and nothing happens. I have tried to remove it, to be able to reinstall it, with the following command sudo apt-get purge cups It finally stalls with the following message Removing cups ... After that nothing happens. The process tree for the apt-get command looks like this. 1404 1404 1404 ? 00:00:00 sshd 26495 26495 26495 ? 00:00:00 sshd 26581 26495 26495 ? 00:00:00 sshd 26582 26582 26582 pts/4 00:00:00 bash 27158 27158 26582 pts/4 00:00:00 apt-get 27172 27172 27172 pts/2 00:00:00 dpkg 27176 27172 27172 pts/2 00:00:00 cups.prerm 27178 27172 27172 pts/2 00:00:00 stop I have tried to leave the process running for a while to see if i get any error messages but without success. To get out of it I have to kill the processes. sudo dpkg --configure cups dpkg: error processing cups (--configure): package cups is already installed and configured Errors were encountered while processing: cups sudo dpkg --status cups Package: cups Status: purge ok installed Priority: optional Section: net Installed-Size: 8292 Maintainer: Ubuntu Developers <[email protected]> Architecture: amd64 Version: 1.4.4-6ubuntu2.3 Replaces: cupsddk-drivers (<< 1.4.0) Provides: cupsddk-drivers Depends: libavahi-client3 (>= 0.6.16), libavahi-common3 (>= 0.6.16), libc6 (>= 2.7), libcups2 (>= 1.4.4-3~), libcupscgi1 (>= 1.4.2), libcupsdriver1 (>= 1.4.0), libcupsimage2 (>= 1.4.0), libcupsmime1 (>= 1.4.0), libcupsppdc1 (>= 1.4.0), libdbus-1-3 (>= 1.0.2), libgcc1 (>= 1:4.1.1), libgnutls26 (>= 2.7.14-0), libgssapi-krb5-2 (>= 1.8+dfsg), libijs-0.35, libkrb5-3 (>= 1.6.dfsg.2), libldap-2.4-2 (>= 2.4.7), libpam0g (>= 0.99.7.1), libpaper1, libpoppler7, libslp1, libstdc++6 (>= 4.1.1), libusb-0.1-4 (>= 2:0.1.12), zlib1g (>= 1:1.1.4), debconf (>= 1.2.9) | debconf-2.0, upstart-job, poppler-utils (>= 0.12), procps, ghostscript, lsb-base (>= 3), cups-common (>= 1.4.4), cups-client (>= 1.4.4-6ubuntu2.3), ssl-cert (>= 1.0.11), adduser, bc, ttf-freefont, cups-ppdc Recommends: foomatic-filters (>= 4.0), cups-driver-gutenprint, ghostscript-cups Suggests: cups-bsd, foomatic-db-compressed-ppds | foomatic-db, hplip, xpdf-korean | xpdf-japanese | xpdf-chinese-traditional | xpdf-chinese-simplified, cups-pdf, smbclient (>= 3.0.9), udev Breaks: foomatic-filters (<< 4.0) Conflicts: cupsddk-drivers (<< 1.4.0) Conffiles: /etc/fonts/conf.d/99pdftoopvp.conf a5221cfad70a981c80864229ef56586d /etc/logrotate.d/cups 5bb41fa9900f0d1c565954405a2bd7c4 /etc/default/cups 2b436fbb1a32b82b6aba45a76a1d7e40 /etc/pam.d/cups ff2488324854f7b1e892bb0df062d5f0 /etc/init/cups.conf 1a3cd022e8474e3d2b44640f33ce68e3 /etc/ufw/applications.d/cups 29e98a6d850da251e180c3d68dec2bd3 /etc/apparmor.d/usr.sbin.cupsd 60c4b26bfd5c033baa3dd48a3b2e9911 /etc/cups/cupsd.conf e2c7ec15835ea0939e5e86f7c6efcc03 /etc/cups/snmp.conf 2326a8af1e112676d55245bc5eb459ca /etc/cups/cupsd.conf.default a68d54d76021e857dd1d64edf57d36c5 Description: Common UNIX Printing System(tm) - server The Common UNIX Printing System (or CUPS(tm)) is a printing system and general replacement for lpd and the like.

  • 3D Ray Casting / Picking

    - by Chris
    Hi, I am not sure if I should post this link, but I feel this falls into game development just as much as it does math. I have a ray cast's far and near values and I am trying to calculate the end point of the ray so that I can either draw a line to show the ray, or render an object at the end of 3d mouse position. Here is my post on the stack overflow math site, if there is a problem with me doing this just close the thread. Thank you. http://math.stackexchange.com/questions/15918/help-with-matrix-mathematica

  • Transitioning from Oracle based CMS to MySQL based CMS

    - by KM01
    We're looking at a replacement for our CMS which runs on Oracle. The new CMSes that we've looked at can in theory run on Oracle, but most of the vendor's installs run off of MySQL vendor supports install of their CMS on MySQL, and a "theoretical" install on Oracle the vendor's dev shops use MySQL none of them develop/test against Oracle Our DBA team works exclusively with Oracle, and doesn't have the bandwidth to provide additional support for a highly available and performing MySQL setup. They could in theory go to training and get ramped up, but our time line is also short (surprise!). So ... I guess my question(s) are: If you've seen a situation like this, how have you dealt with it? What tipped the balance either way? What type of effort did it take? If you're to do it over, what would you do differently ... ? Thanks! KM

A user agent is a “string” – that is, a line of text – identifying the browser and operating system to the web server. This sounds simple, but user agents have become a mess over time.

  • Mysql my.cnf as simbolic link in Ubuntu 12.04

    - by Juan Cruz
    I am not able to use symlink for my.cnf file (Ubuntu 12.04 server). I added the alias to /etc/apparmor.d/tunables/alias file (as I did for 10.04 and worked) but I get: May 30 16:00:01 ip-10-242-209-203 kernel: [176926.213403] type=1400 audit(1338393601.350:244): apparmor="DENIED" operation="open" parent=1 profile="/usr/sbin/mysqld" name="/opt/data/my.cnf" pid=18128 comm="mysqld" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 May 30 16:00:01 ip-10-242-209-203 kernel: [176926.222016] init: mysql main process (18128) terminated with status 1 May 30 16:00:01 ip-10-242-209-203 kernel: [176926.222084] init: mysql respawning too fast, stopped As a workaround I added the following line /etc/mysql/my.cnf r, to the /etc/apparmor.d/local/usr.sbin.mysqld file. The default configuration is /etc/mysql/*.cnf r, Is this a bug? is an apparmor bug or a mysql bug? It seems that that configuration has changed since MySql 5.1 (https://bugs.launchpad.net/ubuntu/+source/mysql-5.1/+bug/619172) but now worked for me. Thanks!

  • Replicate between mysql 5.0.xx community and enterprise edition over ssh

    - by Arlukin
    I'm trying to setup a mysql replication over an SSH tunnel. The odd thing about this setup is that I have one master with mysql 5.0.60sp1-enterprise-gpl-log and one slave with mysql 5.0.67-community-log. Could it be so that it's not possible to replicate between community and enterprise edition? As you can see in my log below, it's possible to login on the remote server with the mysql client. But the replication get "Can't connect to MySQL server on '127.0.0.1' (13)" Is it any log file I have forgotten to look in, to get more info?

  • Ubuntu 11.10 cannot boot. It stucks at BusyBox

    - by Ivan Dokov
    I am using Ubuntu 11.10. An hour ago I had my laptop Sony Vaio VPCEB1S1E running. I saw there are updates to install and I installed them. Turned off the laptop and now when I want to turn it on. It loads until BusyBox v1.18.4 appear. I've saw what the people suggest in other askubuntu topics. I've booted Puppy Linux from USB, repaired the partition where the Ubuntu is installed. Rebooted and nothing changed. I saw other suggestions like writing "exit" in the command line when the BusyBox comes. This didn't help neither. I love the Ubuntu OS, but these days I get similar problem with not able to boot OS. The last times I could repair it with Gparted, but then it wasn't problem with the BusyBox, it was something missing in the OS, like "cannot boot /". The same problem occurred on an older version of Ubuntu 10.10 and there I've repaired it again with Gparted.

  • Context Issue in ASP.NET MVC 3 Unobtrusive Ajax

    - by imran_ku07
        Introduction:          One of the coolest feature you can find in ASP.NET MVC 3 is Unobtrusive Ajax and Unobtrusive Client Validation which separates the javaScript behavior and functionality from the contents of a web page. If you are migrating your ASP.NET MVC 2 (or 1) application to ASP.NET MVC 3 and leveraging the Unobtrusive Ajax feature then you will find that the this context in the callback function is not the same as in ASP.NET MVC 2(or 1). In this article, I will show you the issue and a simple solution.       Description:           The easiest way to understand the issue is to start with an example. Create an ASP.NET MVC 3 application. Then add the following javascript file references inside your page,   <script src="@Url.Content("~/Scripts/MicrosoftAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/MicrosoftMvcAjax.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>             Then add the following lines into your view,   @Ajax.ActionLink("About", "About", new AjaxOptions { OnSuccess = "Success" }) <script type="text/javascript"> function Success(data) { alert(this.innerHTML) } </script>              Next, disable Unobtrusive Ajax feature from web.config,   <add key="UnobtrusiveJavaScriptEnabled" value="false"/>              Then run your application and click the About link, you will see the alert window with "About" message on the screen. This shows that the this context in the callback function is the element which is clicked. Now, let's see what will happen when we leverage Unobtrusive Ajax feature. Now enable Unobtrusive Ajax feature from web.config,     <add key="UnobtrusiveJavaScriptEnabled" value="true"/>              Then run your application again and click the About link again, this time you will see the alert window with "undefined" message on the screen. This shows that the this context in the callback function is not the element which is clicked. Here, this context in the callback function is the Ajax settings object provided by jQuery. This may not be desirable because your callback function may need the this context as the element which triggers the Ajax request. The easiest way to make the this context as the element which triggers the Ajax request is to add this line in jquery.unobtrusive-ajax.js file just before $.ajax(options) line,   options.context = element;              Then run your application again and click the About link again, you will find that the this context in the callback function remains same whether you use Unobtrusive Ajax or not.       Summary:          In this article I showed you a breaking change and a simple workaround in ASP.NET MVC 3. If you are migrating your application from ASP.NET MVC 2(or 1) to ASP.NET MVC 3 and leveraging Unobtrusive Ajax feature then you need to consider this breaking change. Hopefully you will enjoy this article too.     SyntaxHighlighter.all()

  • Bullet physics debug drawing not working

    - by Krishnabhadra
    Background I am following on from this question, which isn't answered yet. Basically I have a cube and a UVSphere in my scene, with UVSphere on the top of the cube without touching the cube. Both exported from blender. When I run the app The UVSphere does circle around the cube for 3 or 4 times and jump out of the scene. What I actually expect was the sphere to fall on top of the cube. What this question about From the comment to the linked question, I got to know about bullet debug drawing, which helps in debugging by drawing outline of physics bodies which are normally invisible. I did some research on that and came up with the code given below. From whatever I have read, below code should work, but it doesn't. My Code My bullet initialization code. -(void) initializeScene { /*Setup physics world*/ _physicsWorld = [[CC3PhysicsWorld alloc] init]; [_physicsWorld setGravity:0 y:-9.8 z:0]; /*Setting up debug draw*/ MyDebugDraw *draw = new MyDebugDraw; draw->setDebugMode(draw->getDebugMode() | btIDebugDraw::DBG_DrawWireframe ); _physicsWorld._discreteDynamicsWorld->setDebugDrawer(draw); /*Setup camera and lamb*/ ………….. //This simpleCube.pod contains the cube [self addContentFromPODFile: @"simpleCube.pod"]; //This file contains sphere [self addContentFromPODFile: @"SimpleSphere.pod"]; [self createGLBuffers]; CC3MeshNode* cubeNode = (CC3MeshNode*)[self getNodeNamed:@"Cube"]; CC3MeshNode* sphereNode = (CC3MeshNode*)[self getNodeNamed:@"Sphere"]; // both cubeNode and sphereNode are not nil from this point float *cVertexData = (float*)((CC3VertexArrayMesh*)cubeNode.mesh) .vertexLocations.vertices; int cVertexCount = ((CC3VertexArrayMesh*)cubeNode.mesh) .vertexLocations.vertexCount; btTriangleMesh* cTriangleMesh = new btTriangleMesh(); int offset = 0; for (int i = 0; i < (cVertexCount / 3); i++) { unsigned int index1 = offset; unsigned int index2 = offset+6; unsigned int index3 = offset+12; cTriangleMesh->addTriangle( btVector3(cVertexData[index1], cVertexData[index1+1], cVertexData[index1+2]), btVector3(cVertexData[index2], cVertexData[index2+1], cVertexData[index2+2]), btVector3(cVertexData[index3], cVertexData[index3+1], cVertexData[index3+2])); offset += 18; } [self releaseRedundantData]; /*Create a triangle mesh from the vertices*/ btBvhTriangleMeshShape* cTriMeshShape = new btBvhTriangleMeshShape(cTriangleMesh,true); btCollisionShape *sphereShape = new btSphereShape(1); gTriMeshObject = [_physicsWorld createPhysicsObjectTrimesh:cubeNode shape:cTriMeshShape mass:0 restitution:1.0 position:cubeNode.location]; sphereObject = [_physicsWorld createPhysicsObject:sphereNode shape:sphereShape mass:1 restitution:0.1 position:sphereNode.location]; sphereObject.rigidBody->setDamping(0.1,0.8); /*Enable debug drawing*/ _physicsWorld._discreteDynamicsWorld->debugDrawWorld(); } And My btIDebugDraw implementation (MyDebugDraw.h) //MyDebugDraw.h class MyDebugDraw: public btIDebugDraw{ int m_debugMode; public: virtual void drawLine(const btVector3& from,const btVector3& to ,const btVector3& color); virtual void drawContactPoint(const btVector3& PointOnB ,const btVector3& normalOnB,btScalar distance ,int lifeTime,const btVector3& color); virtual void reportErrorWarning(const char* warningString); virtual void draw3dText(const btVector3& location ,const char* textString); virtual void setDebugMode(int debugMode); virtual int getDebugMode() const; }; void MyDebugDraw::drawLine(const btVector3& from,const btVector3& to ,const btVector3& color){ LogInfo(@"Works!!"); glPushMatrix(); glColor4f(color.getX(), color.getY(), color.getZ(), 1.0); const GLfloat line[] = { from.getX()*1, from.getY()*1, from.getZ()*1, //point A to.getX()*1, to.getY()*1,to.getZ()*1 //point B }; glVertexPointer( 3, GL_FLOAT, 0, &line ); glPointSize( 5.0f ); glDrawArrays( GL_POINTS, 0, 2 ); glDrawArrays( GL_LINES, 0, 2 ); glPopMatrix(); } void MyDebugDraw::drawContactPoint(const btVector3 &PointOnB ,const btVector3 &normalOnB, btScalar distance ,int lifeTime, const btVector3 &color){ } void MyDebugDraw::reportErrorWarning(const char *warningString){ } void MyDebugDraw::draw3dText(const btVector3 &location , const char *textString){ } void MyDebugDraw::setDebugMode(int debugMode){ } int MyDebugDraw::getDebugMode() const{ return DBG_DrawWireframe; } My Problem The drawLine method is getting called. I can see the cube and sphere in place. Sphere again does some circling around the cube before jumping off. No debug lines are getting drawn.

  • Uploading to a PPA using quickly

    - by Andres
    I am trying to participate in ubuntu showdown. I followed Jono's tutorial to do a browser using quickly. I did some modifications including choosing license (gpl v3), putting my name in copy right ( without special spanish charecters since quicky does not like it) $quickly run to make sure it worked I used bazaar to commit a change with a line of comment. I packaged it using quickly. Managed to install it ignoring some warnings but it would not run. I want to share code to get feedback. I have a launchpad account, signed terms and coditions, created a ppa. I got my commandline to talk to lauchpad using the encription key. But when I run $quickly release or $quickly share and it says the project does not exist. There seems to be another command $dput ... But i don't seem to get the wording right because it requests some sort of signed file that i cannot manage to add the correct way.

  • "Build your own website" - Developing a CMS with Vague Requirements on a Tight Deadline

    - by walnutmon
    I'm a Java developer in charge of making a product which allows clients to "build their own site". I've spent a lot of time looking into Liferay, as I don't have any experience in building CMSs, and want to either use it, or get ideas of how to build a decent system. The time line is short, requirements are vague, yada yada Is Liferay a good technology to work with when showing the client (who may be very low on computer expertise) a user interface to build a site? The thing is, I want the power and flexibility to avoid the learning curve in building a CMS like product, but I don't want to waste time learning a new technology only to find its over-kill, or can't do the simple - but uncommon and unimplemented - things that we are asked to add as features Ideally I'd like to provide multiple web interfaces to the core API to build the sites - one that is very powerful, and another that is watered down and easy to use.

  • End user query syntax?

    - by weberc2
    I'm making a command line tool that allows end users to query a statically-schemed database; however, I want users to be able to specify boolean matchers in their query (effectively things like "get rows where (field1=abcd && field2=efgh) || field3=1234"). I did Googling a solution, but I couldn't find anything suitable for end users--still, this seems like it would be a very common problem so I suspect there is a standard solution. So: What (if any) standard query "languages" are there that might be appropriate for end users? What (if any) de facto standards are there (for example, Unix tools that solve similar problems). Failing the previous two options, can you suggest a syntax that would be simple, concise, and easy to validate?

  • Cannot set a credential for principal 'sa'

    - by hailey
    I was trying to change the SA password on my development server this morning and got an error. Msg 15535, Level 16, State 1, Line 1 Cannot set a credential for principal 'sa'. It was a little frustrating to get an error for a seemingly simple task but then agian maybe I screwed something up.  After doing a couple of searches i found a Microsoft KB (support.microsoft.com/kb/956177) "You receive an exception in SQL Server 2008 when you try to modify the properties of the SQL Server Administrator account by using SQL Server Management Studio".  It was for SQL 2008 but it worked for my SQL 2005 sp3 server just fine.  You have to click the Map to Credential check box but you don't have to add any credetials just click the OK button to complete and that's it.

  • SQL University: Database testing and refactoring tools and examples

    - by Mladen Prajdic
    This is a post for a great idea called SQL University started by Jorge Segarra also famously known as SqlChicken on Twitter. It’s a collection of blog posts on different database related topics contributed by several smart people all over the world. So this week is mine and we’ll be talking about database testing and refactoring. In 3 posts we’ll cover: SQLU part 1 - What and why of database testing SQLU part 2 - What and why of database refactoring SQLU part 3 - Database testing and refactoring tools and examples This is the third and last part of the series and in it we’ll take a look at tools we can test and refactor with plus some an example of the both. Tools of the trade First a few thoughts about how to go about testing a database. I'm firmily against any testing tools that go into the database itself or need an extra database. Unit tests for the database and applications using the database should all be in one place using the same technology. By using database specific frameworks we fragment our tests into many places and increase test system complexity. Let’s take a look at some testing tools. 1. NUnit, xUnit, MbUnit All three are .Net testing frameworks meant to unit test .Net application. But we can test databases with them just fine. I use NUnit because I’ve always used it for work and personal projects. One day this might change. So the thing to remember is to be flexible if something better comes along. All three are quite similar and you should be able to switch between them without much problem. 2. TSQLUnit As much as this framework is helpful for the non-C# savvy folks I don’t like it for the reason I stated above. It lives in the database and thus fragments the testing infrastructure. Also it appears that it’s not being actively developed anymore. 3. DbFit I haven’t had the pleasure of trying this tool just yet but it’s on my to-do list. From what I’ve read and heard Gojko Adzic (@gojkoadzic on Twitter) has done a remarkable job with it. 4. Redgate SQL Refactor and Apex SQL Refactor Neither of these refactoring tools are free, however if you have hardcore refactoring planned they are worth while looking into. I’ve only used the Red Gate’s Refactor and was quite impressed with it. 5. Reverting the database state I’ve talked before about ways to revert a database to pre-test state after unit testing. This still holds and I haven’t changed my mind. Also make sure to read the comments as they are quite informative. I especially like the idea of setting up and tearing down the schema for each test group with NHibernate. Testing and refactoring example We’ll take a look at the simple schema and data test for a view and refactoring the SELECT * in that view. We’ll use a single table PhoneNumbers with ID and Phone columns. Then we’ll refactor the Phone column into 3 columns Prefix, Number and Suffix. Lastly we’ll remove the original Phone column. Then we’ll check how the view behaves with tests in NUnit. The comments in code explain the problem so be sure to read them. I’m assuming you know NUnit and C#. T-SQL Code C# test code USE tempdbGOCREATE TABLE PhoneNumbers( ID INT IDENTITY(1,1), Phone VARCHAR(20))GOINSERT INTO PhoneNumbers(Phone)SELECT '111 222333 444' UNION ALLSELECT '555 666777 888'GO-- notice we don't have WITH SCHEMABINDINGCREATE VIEW vPhoneNumbersAS SELECT * FROM PhoneNumbersGO-- Let's take a look at what the view returns -- If we add a new columns and rows both tests will failSELECT *FROM vPhoneNumbers GO -- DoesViewReturnCorrectColumns test will SUCCEED -- DoesViewReturnCorrectData test will SUCCEED -- refactor to split Phone column into 3 partsALTER TABLE PhoneNumbers ADD Prefix VARCHAR(3)ALTER TABLE PhoneNumbers ADD Number VARCHAR(6)ALTER TABLE PhoneNumbers ADD Suffix VARCHAR(3)GO-- update the new columnsUPDATE PhoneNumbers SET Prefix = LEFT(Phone, 3), Number = SUBSTRING(Phone, 5, 6), Suffix = RIGHT(Phone, 3)GO-- remove the old columnALTER TABLE PhoneNumbers DROP COLUMN PhoneGO-- This returns unexpected results!-- it returns 2 columns ID and Phone even though -- we don't have a Phone column anymore.-- Notice that the data is from the Prefix column-- This is a danger of SELECT *SELECT *FROM vPhoneNumbers -- DoesViewReturnCorrectColumns test will SUCCEED -- DoesViewReturnCorrectData test will FAIL -- for a fix we have to call sp_refreshview -- to refresh the view definitionEXEC sp_refreshview 'vPhoneNumbers'-- after the refresh the view returns 4 columns-- this breaks the input/output behavior of the database-- which refactoring MUST NOT doSELECT *FROM vPhoneNumbers -- DoesViewReturnCorrectColumns test will FAIL -- DoesViewReturnCorrectData test will FAIL -- to fix the input/output behavior change problem -- we have to concat the 3 columns into one named PhoneALTER VIEW vPhoneNumbersASSELECT ID, Prefix + ' ' + Number + ' ' + Suffix AS PhoneFROM PhoneNumbersGO-- now it works as expectedSELECT *FROM vPhoneNumbers -- DoesViewReturnCorrectColumns test will SUCCEED -- DoesViewReturnCorrectData test will SUCCEED -- clean upDROP VIEW vPhoneNumbersDROP TABLE PhoneNumbers [Test]public void DoesViewReturnCoorectColumns(){ // conn is a valid SqlConnection to the server's tempdb // note the SET FMTONLY ON with which we return only schema and no data using (SqlCommand cmd = new SqlCommand("SET FMTONLY ON; SELECT * FROM vPhoneNumbers", conn)) { DataTable dt = new DataTable(); dt.Load(cmd.ExecuteReader(CommandBehavior.CloseConnection)); // test returned schema: number of columns, column names and data types Assert.AreEqual(dt.Columns.Count, 2); Assert.AreEqual(dt.Columns[0].Caption, "ID"); Assert.AreEqual(dt.Columns[0].DataType, typeof(int)); Assert.AreEqual(dt.Columns[1].Caption, "Phone"); Assert.AreEqual(dt.Columns[1].DataType, typeof(string)); }} [Test]public void DoesViewReturnCorrectData(){ // conn is a valid SqlConnection to the server's tempdb using (SqlCommand cmd = new SqlCommand("SELECT * FROM vPhoneNumbers", conn)) { DataTable dt = new DataTable(); dt.Load(cmd.ExecuteReader(CommandBehavior.CloseConnection)); // test returned data: number of rows and their values Assert.AreEqual(dt.Rows.Count, 2); Assert.AreEqual(dt.Rows[0]["ID"], 1); Assert.AreEqual(dt.Rows[0]["Phone"], "111 222333 444"); Assert.AreEqual(dt.Rows[1]["ID"], 2); Assert.AreEqual(dt.Rows[1]["Phone"], "555 666777 888"); }}   With this simple example we’ve seen how a very simple schema can cause a lot of problems in the whole application/database system if it doesn’t have tests. Imagine what would happen if some outside process would depend on that view. It would get wrong data and propagate it silently throughout the system. And that is not good. So have tests at least for the crucial parts of your systems. And with that we conclude the Database Testing and Refactoring week at SQL University. Hope you learned something new and enjoy the learning weeks to come. Have fun!

  • Objective-c Cocos2d moving a sprite

    - by marcg11
    I hope someone knows how to do the following with cocos2d: I want a sprite to move but not in a single line by using [cocosGuy runAction: [CCMoveTo actionWithDuration:1 position:location]]; What I want is the sprite to do some kind of movements that I preestablish. For example in some point i want the sprirte to move for instance up and then down but in a curve. Do I have to do this with flash like this documents says? http://www.cocos2d-iphone.org/wiki/doku.php/prog_guide:animation Does animation in this page means moving sprites or what? thanks

  • how to point godaddy to my entrydns domain

    - by geminiCoder
    I have a server connected via dynamic ip. I have set up entrydns to manage the change of my ip. If I put in my entrydns url it points me to my servers current ip. I purchased a domain from go daddy, but I have been unable to get it to point to my entrydns. What I want is to be able to ssh to my server. but ideally id like to do this by using my domain name. I must confess Im a bit overwhelmed by the godaddy interface. So The bottom line is how do I point my godaddy domain to my dns domain so that when I look up the domain I get the current ip of the server?
