• VSDB to SSDT Part 1 : Converting projects and trimming excess files

  - by Etienne Giust

  Visual Studio 2012 introduces a change regarding Database Projects : they now use the SSDT technology, which means old VS2010 database projects (VSDB projects) need to be converted. Hopefully, VS2012 does that for you and it is quite painless, but in my case some unnecessary artifacts from the old project were left in place.  Also, when reopening the solution, database projects appeared unconverted even if I had converted them in the previous session and saved the solution.   Converting the project(s) When opening your Visual Studio 2010 solution with Visual Studio 2012, every standard project should be converted by default, but Visual Studio will ask you about your database projects : “Functional changes required Visual Studio will automatically make functional changes to the following projects in order to open them. The project behavior will change as a result. You will be able to open these projects in this version and Visual Studio 2010 SP1.” If you accept, your project is converted. And it should compile with no errors right away except if you have dependencies to dbschema files which are no longer supported.   The output of a SSDT project is a dacpac file which replaces the dbschema file you were accustomed to. References to dacpac files can be added to SSDT projects in the same fashion references to dbschema could be added to VSDB projects.   Cleaning up You will notice that your project file is now a sqlproj file but the old dbproj is still here. In fact at that point you can still reopen the solution in Visual Studio 2010 and everything should show up.   If like me you plan on using VS2012 exclusively, you can get rid of the following files which are still on your disk and in your source control : the dbproj and dbproj.vspscc files Properties/Database.sqlcmdvars Properties/Database.sqldeployment Properties/Database.sqlpermissions Properties/Database.sqlsettings   You might wonder where the information which used to be in the Properties files is now stored. Permissions : a Permissions.sql was created at the root level of your project. Note that when you create a new database project and import a database using the Schema Compare capabilities from Visual Studio, imported table and stored procedure definition files will hold the permission information (along with constraints and, indexes) SQLVars : they are defined inside the publish.xml files Deployment : they are also in the publish.xml files Settings : I was unable to find where those are now. I suppose they are not defined anymore   But Visual Studio still says my database projects should be converted ! I had this error upon closing and then re-opening the solution : my database projects would appear unconverted even though I did all the necessary steps previously.   Easy solution : remove those projects from the solution and add them again (the sqlproj files).   More For those who run into problems when converting from VSDB to SSDT, I suggest reading the following post : http://blogs.msdn.com/b/ssdt/archive/2011/11/21/top-vsdb-gt-ssdt-project-conversion-issues.aspx   Also interesting, is a side by side comparison of VSDB and SSDT project features : http://blogs.msdn.com/b/ssdt/archive/2011/11/21/sql-server-data-tools-ctp4-vs-vs2010-database-projects.aspx

• Travelling MVP #3: Community event in Varna, Bulgaria

  - by DigiMortal

  Second stop in my DevReach 2012 trip was at Varna. We had not much time to hang around there but this problem will get fixed next year if not before. But still we had sessions there with Dimitar Georgijev and I had also chance to meet local techies. Next time we will have more tech and beers for sure! We started in the morning from Bucharest and travelled through Ruse, Razgrad and Shumen to Varna. It’s about 275km. We used cab, local bus and Dimitar father’s car. We had one food stop in Ruse and after that we went directly to Varna. Here is our route on map. Varna is Bulgarian city that locates on western coast of Black Sea. I have been there once before this trip and it’s good place to have vacation under sun. Also autumn is there milder than here in Estonia (third day of snow is going on). Bulgaria has some good beers, my favorite mankind killer called rakia and very good national cuisine. Food is made of fresh stuff and it is damn good experience. Here are some arbitrarily selected images (you can click on these to view at original size): Old bus “monument” in Razgrad Stuffed peppers, Bulgarian national cuisine Infra-red community having good time and beers We made our sessions at one study class of Varna technical university. It’s a little bit old style university but everything we needed was there and we had no problems with machinery. Sessions were same as in Bucharest. The user group in Varna is brand new and hopefully it will be something bigger one good day. At least I try to make my commits so they get on their feet quicker. As we had not much time to announce the event there was about 15 guys listening to us and I’m happy that it was not too much hyped event because still I was getting my first experiences with foreign audiences. After sessions we took our stuff to hotel and went to hang around with local techies. We had some good time there and made some new friends. Next time when I go to Varna I go back as more experienced speaker and I plan to do there one tougher and highly challenging session. Maybe somebody from Estonian community will join me and then it will be well planned surprise-attack to Varna :)

• OpenGL - have object follow mouse

  - by kevin james

  I want to have an object follow around my mouse on the screen in OpenGL. (I am also using GLEW, GLFW, and GLM). The best idea I've come up with is: Get the coordinates within the window with glfwGetCursorPos. The window was created with window = glfwCreateWindow( 1024, 768, "Test", NULL, NULL); and the code to get coordinates is double xpos, ypos; glfwGetCursorPos(window, &xpos, &ypos); Next, I use GLM unproject, to get the coordinates in "object space" glm::vec4 viewport = glm::vec4(0.0f, 0.0f, 1024.0f, 768.0f); glm::vec3 pos = glm::vec3(xpos, ypos, 0.0f); glm::vec3 un = glm::unProject(pos, View*Model, Projection, viewport); There are two potential problems I can already see. The viewport is fine, as the initial x,y, coordinates of the lower left are indeed 0,0, and it's indeed a 1024*768 window. However, the position vector I create doesn't seem right. The Z coordinate should probably not be zero. However, glfwGetCursorPos returns 2D coordinates, and I don't know how to go from there to the 3D window coordinates, especially since I am not sure what the 3rd dimension of the window coordinates even means (since computer screens are 2D). Then, I am not sure if I am using unproject correctly. Assume the View, Model, Projection matrices are all OK. If I passed in the correct position vector in Window coordinates, does the unproject call give me the coordinates in Object coordinates? I think it does, but the documentation is not clear. Finally, to each vertex of the object I want to follow the mouse around, I just increment the x coordinate by un[0], the y coordinate by -un[1], and the z coordinate by un[2]. However, since my position vector that is being unprojected is likely wrong, this is not giving good results; the object does move as my mouse moves, but it is offset quite a bit (i.e. moving the mouse a lot doesn't move the object that much, and the z coordinate is very large). I actually found that the z coordinate un[2] is always the same value no matter where my mouse is, probably because the position vector I pass into unproject always has a value of 0.0 for z. Edit: The (incorrectly) unprojected x-values range from about -0.552 to 0.552, and the y-values from about -0.411 to 0.411.

• How to Create a Realistic Timeline for your Projects

  - by Aditi

  Developing a Realistic project time line is a biggest and most challenging task of any team. We here at JustSkins, have learned over time that developing and adhering to a timeline isn’t easy but is not impossible. Keeping in consideration from any technical glitches to a human resource issue, unexpected complications can come up at any time during the entire project life cycle, How ever there are many things you can do in order to save the project from going off-track there. A specific timeline is very important statistic for time management planning and keeping your client informed of the progress. Have a rigid time tracking assures the client, that you are committed to achieving specific project milestones in time. The more you work on varied IT projects, the more you know about the aspects of project and you get to better develop future estimates and timelines. Make a Structure When estimating the time required to accomplish each task, consider which all team members will be involved, also assign the amount of time each individual must put in to the project. Define Scope & dependability and set deadlines for accomplishing them. Sometimes Working in Phases or modules help in doing more in lesser time. One must use a Project management tool in order to systematize the collaboration between the team members. Realistic Goal Setting One approach is to keep a bandwidth of few days to deal with delay, errors & incorrect coding issues you are likely to have in the course. It is very realistic to keep delivery date to client different then internal delivery timeline. If your resource is having hard time finishing this task in the time specified, keep some room to give him a day or two extra to accomplish his task. This does not upset client delivery and is the safe way of doing projects. Keep and Insightful Approach Identify potential problems before they delay your project. To be a great IT manager you have to be honest & diplomatic at the same time, it is essential for you to give earlier notice of potential delays or scope changes to your clients. In situation where delay is inevitable you should be in a position to provide immediate, on-demand status progress reports. Learning from past experiences if very important one must keep a track of actual time spent on all aspects of the projects, this will help you create better future estimates and timelines.

• SQL SERVER – Creating All New Database with Full Recovery Model

  - by pinaldave

  Sometimes, complex problems have very simple solutions. Let us see the following email which I received recently. “Hi Pinal, In our system when we create new database, by default, they are all created with the Simple Recovery Model. We have to manually change the recovery model after we create the database. We used the following simple T-SQL code: CREATE DATABASE dbname. We are very frustrated with this situation. We want all our databases to have the Full Recovery Model option by default. We are considering the following methods; please suggest the most efficient one among them. 1) Creating a Policy; when it is violated, the database model can be fixed 2) Triggers at Server Level 3) Automated Job which goes through all the databases and checks their recovery model; if the DBA has not changed the model, then the job will list the Databases and change their recovery model Also, we have a situation where we need a database in the Simple Recovery Model as well – how to white list them? Please suggest the best method.” Indeed, an interesting email! The answer to their question, i.e., which is the best method to fit their needs (white list, default, etc)? It will be NONE of the above. Here is the solution in one line and also the easiest way: Just go to your Model database: Path in SSMS >> Databases > System Databases >> model >> Right Click Properties >> Options >> Recovery Model - Select Full from dropdown. Every newly created database takes its base template from the Model Database. If you create a custom SP in the Model Database, when you create a new database, it will automatically exist in that database. Any database that was already created before making changes in the Model Database will not be affected at all. Creating Policy is also a good method, and I will blog about this in a separate blog post, but looking at current specifications of the reader, I think the Model Database should be modified to have a Full Recovery Option. While writing this blog post, I remembered my another blog post where the model database log file was growing drastically even though there were no transactions SQL SERVER – Log File Growing for Model Database – model Database Log File Grew Too Big. NOTE: Please do not touch the Model Database unnecessary. It is a strict “No.” If you want to create an object that you need in all the databases, then instead of creating it in model database, I suggest that you create a new database called maintenance and create the object there.

• Why is a fully transparent pixel still rendered?

  - by Mr Bell

  I am trying to make a pixel shader that achieves an effect similar to this video http://www.youtube.com/watch?v=f1uZvurrhig&feature=related My basic idea is render the scene to a temp render target then Render the previously rendered image with a slight fade on to another temp render target Draw the current scene on top of that Draw the results on to a render target that persists between draws Draw the results on to the screen But I am having problems with the fading portion. If I have my pixel shader return a color with its A component set to 0, shouldn't that basically amount to drawing nothing? (Assuming that sprite batch blend mode is set to AlphaBlend) To test this I have my pixel shader return a transparent red color. Instead of nothing being drawn, it draws a partially transparent red box. I hope that my question makes sense, but if it doesnt please ask me to clarify Here is the drawing code public override void Draw(GameTime gameTime) { GraphicsDevice.SamplerStates[1] = SamplerState.PointWrap; drawImageOnClearedRenderTarget(presentationTarget, tempRenderTarget, fadeEffect); drawImageOnRenderTarget(sceneRenderTarget, tempRenderTarget); drawImageOnClearedRenderTarget(tempRenderTarget, presentationTarget); GraphicsDevice.SetRenderTarget(null); drawImage(backgroundTexture); drawImage(presentationTarget); base.Draw(gameTime); } private void drawImage(Texture2D image, Effect effect = null) { spriteBatch.Begin(0, BlendState.AlphaBlend, SamplerState.PointWrap, null, null, effect); spriteBatch.Draw(image, new Rectangle(0, 0, width, height), Color.White); spriteBatch.End(); } private void drawImageOnRenderTarget(Texture2D image, RenderTarget2D target, Effect effect = null) { GraphicsDevice.SetRenderTarget(target); drawImage(image, effect); } private void drawImageOnClearedRenderTarget(Texture2D image, RenderTarget2D target, Effect effect = null) { GraphicsDevice.SetRenderTarget(target); GraphicsDevice.Clear(Color.Transparent); drawImage(image, effect); } Here is the fade pixel shader sampler TextureSampler : register(s0); float4 PixelShaderFunction(float2 texCoord : TEXCOORD0) : COLOR0 { float4 c = 0; c = tex2D(TextureSampler, texCoord); //c.a = clamp(c.a - 0.05, 0, 1); c.r = 1; c.g = 0; c.b = 0; c.a = 0; return c; } technique Fade { pass Pass1 { PixelShader = compile ps_2_0 PixelShaderFunction(); } }

• How to Disable the New Geolocation Feature in Google Chrome

  - by Asian Angel

  The latest release of Google Chrome has geolocation enabled by default, and if you are worried about privacy or just don’t want websites to prompt you for your location, we’ve got the quick details on how to turn it off. Readers should note that the new Geolocation feature doesn’t give out your details by default, so don’t panic. It’s also only active, at the time of this writing, in the Dev channel builds of Chrome—so if you are using the regular stable build this feature won’t arrive for a while anyway. Note: If you’re a Firefox user, be sure to check out our guide to disabling geolocation in Firefox 3.x. What’s this Geolocation Feature About? Geolocation is a way for your browser to tell a website about your physical location, so you can get results tailored to where you actually are—for example, if you visited Google Maps it can ask you for your location to give you an accurate picture of where you are. To use this feature in Google Maps, you would click on the small white icon to activate the feature. As soon as you have clicked on the small white icon, a thin green toolbar will appear at the top of the webpage, asking to Allow or Deny.   How to Turn Chrome’s Geolocation Off If you want to turn geolocation off you will need to open the “Chrome Options Window”, navigate to the third tab, and click on the “Content settings… ” button. When the “Content Settings Window” opens go to the “Location Tab” and select “Do not allow any site to track my physical location”. Once that is done close out the “Content Settings & Chrome Options Windows”. When you go back to Google Maps and try using the small white icon again this is the message that you will see at the top of the page. Now that is much better! If you are unhappy with geolocation being enabled by default in the latest Dev Channel release then this will help get the problem sorted out nicely.

• Non-English Character Display in Oracle SQL Developer

  - by thatjeffsmith

  I get a variation on this question at least once a week, if not more frequently. I’m from Israel, and the language on the databases is Hebrew. When I use the old and deprecated SQL*Plus (windows rich client) I can see the hebrew clearly, when I use the latest SQL Developer, I get gibberish. This question appears on the forums about every week or so as well. So what’s the deal? Well, it starts with a basic misunderstanding of NLS Client parameters. These should accurately reflect the language and locality setup on your LOCAL machine. DO NOT COPY what’s set in the database. The these parameters work together with the database so that information can be transferred back and forth correctly. Having the wrong NLS parameters locally can be bad. [ORACLE DOCS]Setting the NLS_LANG parameter properly is essential to proper data conversion. The character set that is specified by the NLS_LANG parameter should reflect the setting for the client operating system. Setting NLS_LANG correctly enables proper conversion from the client operating system character encoding to the database character set. When these settings are the same, Oracle Database assumes that the data being sent or received is encoded in the same character set as the database character set, so character set validation or conversion may not be performed. This can lead to corrupt data if conversions are necessary. OK, so what are you supposed to do? Set the Font! 9 times out of 10, this preference fixes the problem with display issues. Make sure you set a Font that supports the characters you’re trying to display. It’s as simple as that. This preference defines the font used to display characters in the editors and the data grids. If you have it set to a font that doesn’t have Hebrew character support – you’re not going to see Hebrew in SQL Developer. A few years ago…wow, like 15 years ago, I learned that the Tohama Font is pretty Unicode-friendly. Bad Font Selection A Font that’s not non-English friendly Good Font Selection Exact same text, except rendered with the Tahoma font Summary Having problems seeing non-English text in SQL Developer? Check the font! And do not start messing with NLS parameters without talking to your DBA first.

• Language Club

  - by Ben Griswold

  We started a language club at work this week.  Thus far, we have a collective interest in a number of languages: Python, Ruby, F#, Erlang, Objective-C, Scala, Clojure, Haskell and Go. There are more but these 9 received the most votes. During the first few meetings we are going to determine which language we should tackle first. To help make our selection, each member will provide a quick overview of their favored language by answering the following set of questions: Why are you interested in learning “your” language(s). (There’s lots of work, I’m an MS shill, It’s hip and  fun, etc) What type of language is it?  (OO, dynamic, functional, procedural, declarative, etc) What types of problems is your language best suited to solve?  (Algorithms over big data, rapid application development, modeling, merely academic, etc) Can you provide examples of where/how it is being used?  If it isn’t being used, why not?  (Erlang was invented at Ericsson to provide an extremely fault tolerant, concurrent system.) Quick history – Who created/sponsored the language?  When was it created?  Is it currently active? Does the language have hardware support (an attempt was made at one point to create processor instruction sets specific to Prolog), or can it run as an interpreted language inside another language (like Ruby in the JVM)? Are there facilities for programs written in this language to communicate with other languages?  How does this affect its utility? Does the language have a IDE tool support?  (Think Eclipse or Visual Studio) How well is the language supported in terms of books, community and documentation? What’s the number one things which differentiates the language from others?  (i.e. Why is it cool?) How is the language applicability to us as consultants?  What would the impact be of using the language in terms of cost, maintainability, personnel costs, etc.? What’s the number one things which differentiates the language from others?  (i.e. Why is it cool?) This should provide an decent introduction into nearly a dozen languages and give us enough context to decide which single language deserves our undivided attention for the weeks to come.  Stay tuned for the winner…

• Equal Gifts Algorithm Problem

  - by 7Aces

  Problem Link - http://opc.iarcs.org.in/index.php/problems/EQGIFTS It is Lavanya's birthday and several families have been invited for the birthday party. As is customary, all of them have brought gifts for Lavanya as well as her brother Nikhil. Since their friends are all of the erudite kind, everyone has brought a pair of books. Unfortunately, the gift givers did not clearly indicate which book in the pair is for Lavanya and which one is for Nikhil. Now it is up to their father to divide up these books between them. He has decided that from each of these pairs, one book will go to Lavanya and one to Nikhil. Moreover, since Nikhil is quite a keen observer of the value of gifts, the books have to be divided in such a manner that the total value of the books for Lavanya is as close as possible to total value of the books for Nikhil. Since Lavanya and Nikhil are kids, no book that has been gifted will have a value higher than 300 Rupees... For the problem, I couldn't think of anything except recursion. The code I wrote is given below. But the problem is that the code is time-inefficient and gives TLE (Time Limit Exceeded) for 9 out of 10 test cases! What would be a better approach to the problem? Code - #include<cstdio> #include<climits> #include<algorithm> using namespace std; int n,g[150][2]; int diff(int a,int b,int f) { ++f; if(f==n) { if(a>b) { return a-b; } else { return b-a; } } return min(diff(a+g[f][0],b+g[f][1],f),diff(a+g[f][1],b+g[f][0],f)); } int main() { int i; scanf("%d",&n); for(i=0;i<n;++i) { scanf("%d%d",&g[i][0],&g[i][1]); } printf("%d",diff(g[0][0],g[0][1],0)); } Note - It is just a practice question, & is not part of a competition.

• Breadcrumb using and schema.org rich snippets

  - by Adam Jenkin

  I am having problems implementing the breadcrumb rich snippets from schema.org. When I construct my breadcrumb using the documentation and run via Google Rich Snippet testing tool, the breadcrumb is identified but not shown in the preview. <!DOCTYPE html> <html> <head> <title>My Test Page</title> </head> <body itemscope itemtype="http://schema.org/WebPage"> <strong>You are here: </strong> <div itemprop="breadcrumb"> <a title="Home" href="/">Home</a> > <a title="Test Pages" href="/Test-Pages/">Test Pages</a> > </div> </body> </html> If I change to use the snippets from data-vocabulary.org, the rich snippets show correctly in the preview. <!DOCTYPE html> <html> <head> <title>My Test Page</title> </head> <body> <strong>You are here: </strong> <ol itemprop="breadcrumb"> <li itemscope itemtype="http://data-vocabulary.org/Breadcrumb"> <a href="/" itemprop="url"> <span itemprop="title">Home</span> </a> </li> <li itemscope itemtype="http://data-vocabulary.org/Breadcrumb"> <a href="/Test-Pages/" itemprop="url"> <span itemprop="title">Test Pages</span> </a> </li> </ol> </body> </html> I want the breadcrumb to be shown in the search result rather than the url to the page. Given that schema.org is the recommended way to be using rich snippets, I would rather use this, however as the breadcrumb is not showing in the preview of the search result using this method, i'm not convinced this is working correctly. Am I doing something wrong in the markup for schema.org example?

• Atmospheric scattering sky from space artifacts

  - by ollipekka

  I am in the process of implementing atmospheric scattering of a planets from space. I have been using Sean O'Neil's shaders from http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter16.html as a starting point. I have pretty much the same problem related to fCameraAngle except with SkyFromSpace shader as opposed to GroundFromSpace shader as here: http://www.gamedev.net/topic/621187-sean-oneils-atmospheric-scattering/ I get strange artifacts with sky from space shader when not using fCameraAngle = 1 in the inner loop. What is the cause of these artifacts? The artifacts disappear when fCameraAngle is limtied to 1. I also seem to lack the hue that is present in O'Neil's sandbox (http://sponeil.net/downloads.htm) Camera position X=0, Y=0, Z=500. GroundFromSpace on the left, SkyFromSpace on the right. Camera position X=500, Y=500, Z=500. GroundFromSpace on the left, SkyFromSpace on the right. I've found that the camera angle seems to handled very differently depending the source: In the original shaders the camera angle in SkyFromSpaceShader is calculated as: float fCameraAngle = dot(v3Ray, v3SamplePoint) / fHeight; Whereas in ground from space shader the camera angle is calculated as: float fCameraAngle = dot(-v3Ray, v3Pos) / length(v3Pos); However, various sources online tinker with negating the ray. Why is this? Here is a C# Windows.Forms project that demonstrates the problem and that I've used to generate the images: https://github.com/ollipekka/AtmosphericScatteringTest/ Update: I have found out from the ScatterCPU project found on O'Neil's site that the camera ray is negated when the camera is above the point being shaded so that the scattering is calculated from point to the camera. Changing the ray direction indeed does remove artifacts, but introduces other problems as illustrated here: Furthermore, in the ScatterCPU project, O'Neil guards against situations where optical depth for light is less than zero: float fLightDepth = Scale(fLightAngle, fScaleDepth); if (fLightDepth < float.Epsilon) { continue; } As pointed out in the comments, along with these new artifacts this still leaves the question, what is wrong with the images where camera is positioned at 500, 500, 500? It feels like the halo is focused on completely wrong part of the planet. One would expect that the light would be closer to the spot where the sun should hits the planet, rather than where it changes from day to night. The github project has been updated to reflect changes in this update.

  Guest editorial for the ITPro/SysAdmin newsletter The Raspberry Pi Foundation has done a superb design job on their new $35 network-enabled Linux computer. This tiny machine, incorporating an ARM processor on a Broadcom BCM2835 multimedia chip, aims to put the fun back into learning computing. The public response has been overwhelmingly positive.Note that aim: "…to put the fun back". Education in Information Technology is in dire straits. It always has been, but seems to have deteriorated further still, even in the face of improved provision of equipment.In many countries, the government controls the curriculum. It predicted a shortage in office-based IT skills, and so geared the ICT curriculum toward mind-numbing training in word-processing and spreadsheet skills. Instead, the shortage has turned out to be in people with an engineering-mindset, who can solve problems with whatever technologies are available and learn new techniques quickly, in a rapidly-changing field.In retrospect, the assumption that specific training was required rather than an education was an idiotic response to the arrival of mainstream information technology. As a result, ICT became a disaster area, which discouraged a generation of youngsters from a career in IT, and thereby led directly to the shortage of people with the skills that are required to exploit the potential of Information Technology..Raspberry Pi aims to reverse the trend. This is a rig that is geared to fast graphics in high resolution. It is no toy. It should be a superb games machine. However, the use of Fedora, Debian, or Arch Linux ARM shows the more serious educational intent behind the Foundation's work. It looks like it will even do some office work too!So, get hold of any power supply that provides a 5VDC source at the required 700mA; an old Blackberry charger will do or, alternatively, it will run off four AA cells. You'll need a USB hub to support the mouse and keyboard, and maybe a hard drive. You'll want a DVI monitor (with audio out) or TV (sound and video). You'll also need to be able to cope with wired Ethernet 10/100, if you want networking.With this lot assembled, stick the paraphernalia on the back of the HDTV with Blu Tack, get a nice keyboard, and you have a classy Linux-based home computer. The major cost is in the T.V and the keyboard. If you're not already writing software for this platform, then maybe, at a time when some countries are talking of orders in the millions, you should consider it.

• Ati Radeon HD 3200 Graphics driver - Installation Problem

  - by samufi

  I have a fresh installation of Ubuntu 12.04 x86 and I am trying to install the proprietary driver for my "Radeon HD 3200 Graphics" video card. I know that there are already many threads about this topic, but I did not find a solution for my problem: For the installation I followed exactly these instructions: What is the correct way to install ATI Catalyst Video Drivers in 12.04 LTS? During the process I faced these problems: I executed ~$ debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases and got: debconf: DbDriver "passwords" warning: could not open /var/cache/debconf/passwords.dat: Keine Berechtigung Can't exec "libstdc++6": Datei oder Verzeichnis nicht gefunden at /usr/share/perl/5.14/IPC/Open3.pm line 186. open2: exec of libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases failed at /usr/share/perl5/Debconf/ConfModule.pm line 59 (translation of the German parts: "Keine Berechtigung" means: "no permission"; "Datei oder Verzeichnis nicht gefunden" means: "File or folder not found") Because I had no idea if it was a big issue, I just continued: ~$ sudo apt-get install ia32-libs There I got: Paketlisten werden gelesen... Fertig Abhängigkeitsbaum wird aufgebaut Statusinformationen werden eingelesen... Fertig Paket ia32-libs ist nicht verfügbar, wird aber von einem anderen Paket referenziert. Das kann heißen, dass das Paket fehlt, dass es abgelöst wurde oder nur aus einer anderen Quelle verfügbar ist. E: Paket »ia32-libs« hat keinen Installationskandidaten (Translation: [...] the package ia32-libs is not available but is referenced by an other package [...] E: package »ia32-libs« has no installation candidate) Once more I went on. The next steps worked quite fine. But when I came to the point: ~$ sudo dpkg -i *.deb There I got A popup message, something like there was a problem with a system application but in the terminal no errors were reported, also the packages seemed to be installed. so now the Ati Catalyst Center works amdcccle but fglrxinfo gave me X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 139 (ATIFGLEXTENSION) Minor opcode of failed request: 66 () Serial number of failed request: 13 Current serial number in output stream: 13 So there is something wrong. (Also there is not the possibility to enable these nice graphical features - the reason why I installed the proprietary driver) Because I worked with a completely fresh Installation I don't know how to fix the problem. If anybody could help I would be very tahnkful! =)

• Programming and Ubiquitous Language (DDD) in a non-English domain

  - by Sandor Drieënhuizen

  I know there are some questions already here that are closely related to this subject but none of them take Ubiquitous Language as the starting point so I think that justifies this question. For those who don't know: Ubiquitous Language is the concept of defining a (both spoken and written) language that is equally used across developers and domain experts to avoid inconsistencies and miscommunication due to translation problems and misunderstanding. You will see the same terminology show up in code, conversations between any team member, functional specs and whatnot. So, what I was wondering about is how to deal with Ubiquitous Language in non-English domains. Personally, I strongly favor writing programming code in English completely, including comments but ofcourse excluding constants and resources. However, in a non-English domain, I'm forced to make a decision either to: Write code reflecting the Ubiquitous Language in the natural language of the domain. Translate the Ubiquitous Language to English and stop communicating in the natural language of the domain. Define a table that defines how the Ubiquitous Language translates to English. Here are some of my thoughts based on these options: 1) I have a strong aversion against mixed-language code, that is coding using type/member/variable names etc. that are non-English. Most programming languages 'breathe' English to a large extent and most of the technical literature, design pattern names etc. are in English as well. Therefore, in most cases there's just no way of writing code entirely in a non-English language so you end up with mixed languages anyway. 2) This will force the domain experts to start thinking and talking in the English equivalent of the UL, something that will probably not come naturally to them and therefore hinders communication significantly. 3) In this case, the developers communicate with the domain experts in their native language while the developers communicate with each other in English and most importantly, they write code using the English translation of the UL. I'm sure I don't want to go for the first option and I think option 3 is much better than option 2. What do you think? Am I missing other options? UPDATE Today, about year later, having dealt with this issue on a daily basis, I have to say that option 3 has worked out pretty well for me. It wasn't as tedious as I initially feared and translating in real time while talking to the client wasn't a problem either. I also found the following advantages to be true, based on my experience. Translating the UL makes you pay more attention to defining the UL and even the domain itself, especially when you don't know how to translate a term and you have to start looking through dictionaries etc. This has even caused me to reconsider domain modeling decisions a few times. It helps you make your knowledge of the English language more profound. Obviously, your code is much more pleasant to look at instead of being a mind boggling obscenity.

• Tomboy error while tring to sync with Ubuntu one; Can anyone help?

  - by Michael Chapman

  So I'm sure you've heard the song before, but after trying to sync my notes with Ubuntu One(on 10.10 AMD64) I get "Could not synchronize notes. Check the details below and try again." Of course the problem is that there are no details and trying again doesn't help. So I ran tomboy -debug and compared my error to any thing I could find about similar problems (such as the post here) but found nothing useful. Any way here's my first error, I got this using preferencessynchronizationUbuntu_one [ERROR 21:08:42.271] Synchronization failed with the following exception: String was not recognized as a valid DateTime. at System.DateTime.Parse (System.String s, IFormatProvider provider, DateTimeStyles styles) [0x00000] in <filename unknown>:0 at System.DateTime.Parse (System.String s, IFormatProvider provider) [0x00000] in <filename unknown>:0 at System.DateTime.Parse (System.String s) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.NoteInfo.ParseJson (Hyena.Json.JsonObject jsonObj) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.UserInfo.ParseJsonNoteArray (Hyena.Json.JsonArray jsonArray) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.UserInfo.ParseJsonNotes (System.String jsonString, System.Nullable`1& latestSyncRevision) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.Api.UserInfo.GetNotes (Boolean includeContent, Int32 sinceRevision, System.Nullable`1& latestSyncRevision) [0x00000] in <filename unknown>:0 at Tomboy.WebSync.WebSyncServer.GetNoteUpdatesSince (Int32 revision) [0x00000] in <filename unknown>:0 at Tomboy.Sync.SyncManager.SynchronizationThread () [0x00000] in <filename unknown>:0 The next thing I tried was using preferencessynchronizationtomboy_web with the default 'http://one.ubuntu.com/notes/' and got the same error plus one more.

Thanks for any help and please let me know if anything is confusing.

• What are the alternatives to "overriding a method" when using composition instead of inheritance?

  - by Sebastien Diot

  If we should favor composition over inheritance, the data part of it is clear, at least for me. What I don't have a clear solution to is how overwriting methods, or simply implementing them if they are defined in a pure virtual form, should be implemented. An obvious way is to wrap the instance representing the base-class into the instance representing the sub-class. But the major downsides of this are that if you have say 10 methods, and you want to override a single one, you still have to delegate every other methods anyway. And if there were several layers of inheritance, you have now several layers of wrapping, which becomes less and less efficient. Also, this only solve the problem of the object "client"; when another object calls the top wrapper, things happen like in inheritance. But when a method of the deepest instance, the base class, calls it's own methods that have been wrapped and modified, the wrapping has no effect: the call is performed by it's own method, instead of by the highest wrapper. One extreme alternative that would solve those problems would be to have one instance per method. You only wrap methods that you want to overwrite, so there is no pointless delegation. But now you end up with an incredible amount of classes and object instance, which will have a negative effect on memory usage, and this will require a lot more coding too. So, are there alternatives (preferably alternatives that can be used in Java), that: Do not result in many levels of pointless delegation without any changes. Make sure that not only the client of an object, but also all the code of the object itself, is aware of which implementation of method should be called. Does not result in an explosion of classes and instances. Ideally puts the extra memory overhead that is required at the "class"/"particular composition" level (static if you will), rather than having every object pay the memory overhead of composition. My feeling tells me that the instance representing the base class should be at the "top" of the stack/layers so it receives calls directly, and can process them directly too if they are not overwritten. But I don't know how to do it that way.

• Visual Studio 2010 and Target Framework Version

  - by Scott Dorman

  Almost two years ago, I wrote about a Visual Studio macro that allows you to change the Target Framework version of all projects in a solution. If you don’t know, the Target Framework version is what tells the compiler which version of the .NET Framework to compile against (more information is available here) and can be set to one of the following values: .NET Framework 2.0 .NET Framework 3.0 .NET Framework 3.5 .NET Framework 3.5 Client Profile .NET Framework 4.0 .NET Framework 4.0 Client Profile This can be easily accomplished by editing the project properties: The problem with this approach is that if you need to change a lot of projects at one time it becomes rather unwieldy. One possible solution is to edit the project files by hand in a text editor and change the <TargetFrameworkVersion /> and <TargetFrameworkProfile /> properties to the correct values. For example, for the .NET Framework 4.0 Client Profile, these values would be: <TargetFrameworkVersion>v4.0</TargetFrameworkVersion> <TargetFrameworkProfile>Client</TargetFrameworkProfile> Again, this is not only time consuming but can also be error-prone. The better solution is to automate this through the use of a Visual Studio macro. Since I had already created a macro to do this for Visual Studio 2008, I updated that macro to work with Visual Studio 2010 and .NET 4.0. It prompts you for the target framework version you want to set for all of the projects and then loops through each project in the solution and makes the change. If you select one of the Framework versions that support a Client Profile, it will ask if you want to use the Client Profile or the Full Profile. It is smart enough to skip project types that don’t support this property and projects that are already at the correct version. This version also incorporates the changes suggested by George (in the comments). The macro is available on my SkyDrive account. Download it to your <UserProfile>\Documents\Visual Studio 2010\Projects\VSMacros80\MyMacros folder, open the Visual Studio Macro IDE (Alt-F11) and add it as an existing item to the “MyMacros” project. I make no guarantees or warranties on this macro. I have tested it on several solutions and projects and everything seems to work and not cause any problems, but, as always, use with caution. Since it is a macro, you have the full source code available to investigate and see what it’s actually doing. If you find any bugs or make any useful changes, please let me know and I’ll update the macro. Technorati Tags: Macros,Visual Studio

• What's your advise on a potential legal suit? [closed]

  - by ohho

  I [xxx app developer] received an email from Apple that a developer [of yyy app] believes I am "infringing their copyright." Description of Issue: [xxx developer] copied my application (my application is [yyy]) feature by feature. Even their donation model is completely copied from my application. Their first release was significantly later than mine, which implies copying of the application rather than parallel development. I suffered significant financial losses because of their actions, in additional to promotion problems as many people are confused with their product. My advertising was based around the idea of a "free [yyy] application for an iPhone" and they have just taken that as a title for their application. I would appreciate if someone takes a look at their release schedule and compare it to my releases. Additionally, please take a look at their functionality and how it point by point copies the functionality of my older releases. I am asking Apple to remove their application from the App Store, and ban them from resubmitting it. Thank you for your time! [yyy developer], the developer of the [yyy] application. My response was: The code of [xxx] is written by myself, using Apple public API. The graphics elements are designed by myself. The user interface and app control are independently designed and different from other [similar type] apps (please judge yourself). In-app Purchase is iOS Apple standard API. iAd is Apple iOS standard API. I don't think features can be owned exclusively. In fact, my app comes with fewer features, as I prefer minimalist design. I don't think idea can be owned exclusively. Apple responded: Thank you for your response. Unfortunately, Apple cannot serve as arbiter for disputes among third parties. Please contact [yyy developer] directly regarding your actions. You can reach [yyy developer] through: [...]. We look forward to confirmation from both parties that this issue has been resolved. If this issue is not resolved shortly, Apple may be forced to pull your application(s) from the App Store. Then I sent my response above to [yyy developer]. [yyy developer] then asked me "to provide (my) legal address and contact details that (his) lawyer requires to file a copyright infringement suit." IMO, I don't think the [yyy developer]'s claim on "feature by feature" copy is valid. I have fewer features, completely different user interface design. However, I don't think I can afford a legal action for an app of so little financial return. So what's your advise on this? Should I just let Apple pull my app? Or is there any alternative I can consider? FYI ... UI of [xxx app]: and UI of [yyy app]:

• How to refactor a Python “god class”?

  - by Zearin

  Problem I’m working on a Python project whose main class is a bit “God Object”. There are so friggin’ many attributes and methods! I want to refactor the class. So Far… For the first step, I want to do something relatively simple; but when I tried the most straightforward approach, it broke some tests and existing examples. Basically, the class has a loooong list of attributes—but I can clearly look over them and think, “These 5 attributes are related…These 8 are also related…and then there’s the rest.” getattr I basically just wanted to group the related attributes into a dict-like helper class. I had a feeling __getattr__ would be ideal for the job. So I moved the attributes to a separate class, and, sure enough, __getattr__ worked its magic perfectly well… At first. But then I tried running one of the examples. The example subclass tries to set one of these attributes directly (at the class level). But since the attribute was no longer “physically located” in the parent class, I got an error saying that the attribute did not exist. @property I then read up about the @property decorator. But then I also read that it creates problems for subclasses that want to do self.x = blah when x is a property of the parent class. Desired Have all client code continue to work using self.whatever, even if the parent’s whatever property is not “physically located” in the class (or instance) itself. Group related attributes into dict-like containers. Reduce the extreme noisiness of the code in the main class. For example, I don’t simply want to change this: larry = 2 curly = 'abcd' moe = self.doh() Into this: larry = something_else('larry') curly = something_else('curly') moe = yet_another_thing.moe() …because that’s still noisy. Although that successfully makes a simply attribute into something that can manage the data, the original had 3 variables and the tweaked version still has 3 variables. However, I would be fine with something like this: stooges = Stooges() And if a lookup for self.larry fails, something would check stooges and see if larry is there. (But it must also work if a subclass tries to do larry = 'blah' at the class level.) Summary Want to replace related groups of attributes in a parent class with a single attribute that stores all the data elsewhere Want to work with existing client code that uses (e.g.) larry = 'blah' at the class level Want to continue to allow subclasses to extend, override, and modify these refactored attributes without knowing anything has changed Is this possible? Or am I barking up the wrong tree?

• Wordpress Installation (on IIS and SQL Server)

  - by Davide Mauri

  To proceed with the installation of Wordpress on SQL Server and IIS, first of all, you need to do the following steps Create a database on SQL Server that will be used by Wordpress Create login that can access to the just created database and put the user into ddladmin, db_datareader, db_datawriter roles Download and unpack Wordpress 3.3.2 (latest version as of 27 May 2012) zip file into a directory of your choice Download the wp-db-abstraction 1.1.4 (latest version as of 27 May 2012) plugin from wordpress.org website Now that the basic action has been done, you can start to setup and configure your Wordpress installation. Unpack and follow the instructions in the README.TXT file to install the Database Abstraction Layer. Mainly you have to: Upload wp-db-abstraction.php and the wp-db-abstraction directory to wp-content/mu-plugins.  This should be parallel to your regular plugins directory.  If the mu-plugins directory does not exist, you must create it. Put the db.php file from inside the wp-db-abstraction.php directory to wp-content/db.php Now you can create an application pool in IIS like the following one Create a website, using the above Application Pool, that points to the folder where you unpacked Wordpress files. Be sure to give the “Write” permission to the IIS account, as pointed out in this (old, but still quite valid) installation manual: http://wordpress.visitmix.com/development/installing-wordpress-on-sql-server#iis Now you’re ready to go. Point your browser to the configured website and the Wordpress installation screen will be there for you. When you’re requested to enter information to connect to MySQL database, simply skip that page, leaving the default values. If you have installed the Database Abstraction Layer, another database installation screen will appear after the one used by MySQL, and here you can enter the configuration information needed to connect to SQL Server. After having finished the installation steps, you should be able to access and navigate your wordpress site.  A final touch, and it’s done: just add the needed rewrite rules http://wordpress.visitmix.com/development/installing-wordpress-on-sql-server#urlrewrite and that’s it! Well. Not really. Unfortunately the current (as of 27 May 2012) version of the Database Abstraction Layer (1.1.4) has some bugs. Luckily they can be quickly fixed: Backslash Fix http://wordpress.org/support/topic/plugin-wp-db-abstraction-fix-problems-with-backslash-usage Select Top 0 Fix Make the change to the file “.\wp-content\mu-plugins\wp-db-abstraction\translations\sqlsrv\translations.php” suggested by “debettap”   http://sourceforge.net/tracker/?func=detail&aid=3485384&group_id=315685&atid=1328061 And now you have a 100% working Wordpress installation on SQL Server! Since I also wanted to take advantage of SQL Server Full Text Search, I’ve created a very simple wordpress plugin to setup full-text search and to use it as website search engine: http://wpfts.codeplex.com/ Enjoy!

• Music Notation Editor - Refactoring view creation logic elsewhere

  - by Cyril Silverman

  Let me preface by saying that knowing some elementary music theory and music notation may be helpful in grasping the problem at hand. I'm currently building a Music Notation and Tablature Editor (in Javascript). But I've come to a point where the core parts of the program are more or less there. All functionality I plan to add at this point will really build off the foundation that I've created. As a result, I want to refactor to really solidify my code. I'm using an API called VexFlow to render notation. Basically I pass the parts of the editor's state to VexFlow to build the graphical representation of the score. Here is a rough and stripped down UML diagram showing you the outline of my program: In essence, a Part has many Measures which has many Notes which has many NoteItems (yes, this is semantically weird, as a chord is represented as a Note with multiple NoteItems, individual pitches or fret positions). All of the relationships are bi-directional. There are a few problems with my design because my Measure class contains the majority of the entire application view logic. The class holds the data about all VexFlow objects (the graphical representation of the score). It contains the graphical Staff object and the graphical notes. (Shouldn't these be placed somewhere else in the program?) While VexFlowFactory deals with actual creation (and some processing) of most of the VexFlow objects, Measure still "directs" the creation of all the objects and what order they are supposed to be created in for both the VexFlowStaff and VexFlowNotes. I'm not looking for a specific answer as you'd need a much deeper understanding of my code. Just a general direction to go in. Here's a thought I had, create an MeasureView/NoteView/PartView classes that contains the basic VexFlow objects for each class in addition to any extraneous logic for it's creation? but where would these views be contained? Do I create a ScoreView that is a parallel graphical representation of everything? So that ScoreView.render() would cascade down PartView and call render for each PartView and casade down into each MeasureView, etc. Again, I just have no idea what direction to go in. The more I think about it, the more ways to go seem to pop into my head. I tried to be as concise and simplistic as possible while still getting my problem across. Please feel free to ask me any questions if anything is unclear. It's quite a struggle trying to dumb down a complicated problem to its core parts.
