• Oracle Tutor: *** CAUTION to Word .docx Users ***

  - by [email protected]

  Microsoft released a security update KB969604 for Office 2007 (around June 2009) This update causes document variables within Word docx files to be scrambled. This update might still be pushed out via Office 2007 updates DO NOT save files as docx using MS OFFICE 2007 until you apply the MS hotfix # 970942 available here If you are using Windows XP with Office 2003 or Office 2000 and have installed an older Office 2007 compatibility pack, documents saved as docx may also cause the scrambled document variables. Installing the 2007 compatibility pack published on 1/6/2010 (version 4) will prevent the document variables from becoming corrupt. Those on Windows 2000 may not be able to install the latest compatibility pack, or the compatibility pack may not function properly. This situation will hopefully be rectified in the coming months. What is a document variable? Document variables store data inside the document, invisible to the user. The Tutor software uses them when converting the document to HTML and when creating the flowchart, just to name a couple of uses. How will you know if a document's variables are scrambled? The difficulty in diagnosing the issue is that the symptoms can take myriad forms. There isn't a single error message or a single feature that one can point to and say, "test for the problem by doing this." The best clue about the error is seeing any kind of string in an error message that has garbage characters, question marks, xml code snippets, or just nonsense. Such as "Language ?????????????xlr;lwlerkjl could not be found." It is also possible to see the corrupted data in the footers of the Word docs. And, just because the footers look correct does not mean that the document variables are not corrupted. The corruption problem does not occur in every document variable in the document, just some of them. Often it is less than a quarter of them. What is the difference between docx files and doc files? Office 2007 uses Office Open XML formats with .docx and .docm filename extensions. - Docx is an Office Open XML word document. - Docm is a macro enabled Office Open XML document. This means the file structure behind the scenes is quite different from the binary file formats used prior to Office 2007 such as .doc, .dot, .xls, and .ppt. Solution Summary: For Windows XP and Word 2007: Install the hotfix, or save files as *.doc For Windows XP and Word 2000 and 2003: Install the latest compatibility pack or save files as *.doc For Windows 2000 with Word 2000 or 2003, do not use any compatibility pack, save files as *.doc Emily Chorba Principle Product Manager for Oracle Tutor

• SQL SERVER – What is SSAS Tabular Data model and Why to use it – Part 2

  - by Pinal Dave

  In my last article, I talked about the basics of tabular data model and why use it. Then I demonstrated step by step creation of a basic tabular model project. In this part I’m going to throw some light on how to create measures and analyses in excel. If you look at the tabular project closely, you will notice that we have not defined any measure yet. So, in the first step we will define the measure first.  Open the solution and select the column you want to define as a measure. Then, click on the summation icon on the toolbar. You will see the aggregated results at the bottom of that column. You have also other choices as well like average, min, max, count and distinct count. After creating the required measures, we need to analyze our data in excel. To do this, click on the excel icon in the upper left corner of the toolbar. This will open your analysis in excel. Notice the pivot table field list here. I have highlighted the measures that we created in the earlier step. Now, we can use these measures in our analysis Now, we have to put the required fields in their respective places as column labels, row labels, Values and Report filter for analysis. See below snapshot for details, it shows region wise sales on a yearly basis You can even apply filters on the above analysis by placing the slicer field in report filter. In our example, we will take an English product name as a filter. You can use the filter as depicted in the below snapshot. Optionally, you can also use the slider to filter data more interactively. Further to improve our analysis, we can insert pivot charts That’s all for this time, in my next post I’m going to show in detail about how to create hierarchies, perspectives, KPI’s  and many more features.

• How do I calculate the boundary of the game window after transforming the view?

  - by Cypher

  My Camera class handles zoom, rotation, and of course panning. It's invoked through SpriteBatch.Begin, like so many other XNA 2D camera classes. It calculates the view Matrix like so: public Matrix GetViewMatrix() { return Matrix.Identity * Matrix.CreateTranslation(new Vector3(-this.Spatial.Position, 0.0f)) * Matrix.CreateTranslation(-( this.viewport.Width / 2 ), -( this.viewport.Height / 2 ), 0.0f) * Matrix.CreateRotationZ(this.Rotation) * Matrix.CreateScale(this.Scale, this.Scale, 1.0f) * Matrix.CreateTranslation(this.viewport.Width * 0.5f, this.viewport.Height * 0.5f, 0.0f); } I was having a minor issue with performance, which after doing some profiling, led me to apply a culling feature to my rendering system. It used to, before I implemented the camera's zoom feature, simply grab the camera's boundaries and cull any game objects that did not intersect with the camera. However, after giving the camera the ability to zoom, that no longer works. The reason why is visible in the screenshot below. The navy blue rectangle represents the camera's boundaries when zoomed out all the way (Camera.Scale = 0.5f). So, when zoomed out, game objects are culled before they reach the boundaries of the window. The camera's width and height are determined by the Viewport properties of the same name (maybe this is my mistake? I wasn't expecting the camera to "resize" like this). What I'm trying to calculate is a Rectangle that defines the boundaries of the screen, as indicated by my awesome blue arrows, even after the camera is rotated, scaled, or panned. Here is how I've more recently found out how not to do it: public Rectangle CullingRegion { get { Rectangle region = Rectangle.Empty; Vector2 size = this.Spatial.Size; size *= 1 / this.Scale; Vector2 position = this.Spatial.Position; position = Vector2.Transform(position, this.Inverse); region.X = (int)position.X; region.Y = (int)position.Y; region.Width = (int)size.X; region.Height = (int)size.Y; return region; } } It seems to calculate the right size, but when I render this region, it moves around which will obviously cause problems. It needs to be "static", so to speak. It's also obscenely slow, which causes more of a problem than it solves. What am I missing?

• Only draw visible objects to the camera in 2D

  - by Deukalion

  I have Map, each map has an array of Ground, each Ground consists of an array of VertexPositionTexture and a texture name reference so it renders a texture at these points (as a shape through triangulation). Now when I render my map I only want to get a list of all objects that are visible in the camera. (So I won't loop through more than I have to) Structs: public struct Map { public Ground[] Ground { get; set; } } public struct Ground { public int[] Indexes { get; set; } public VertexPositionNormalTexture[] Points { get; set; } public Vector3 TopLeft { get; set; } public Vector3 TopRight { get; set; } public Vector3 BottomLeft { get; set; } public Vector3 BottomRight { get; set; } } public struct RenderBoundaries<T> { public BoundingBox Box; public T Items; } when I load a map: foreach (Ground ground in CurrentMap.Ground) { Boundaries.Add(new RenderBoundaries<Ground>() { Box = BoundingBox.CreateFromPoints(new Vector3[] { ground.TopLeft, ground.TopRight, ground.BottomLeft, ground.BottomRight }), Items = ground }); } TopLeft, TopRight, BottomLeft, BottomRight are simply the locations of each corner that the shape make. A rectangle. When I try to loop through only the objects that are visible I do this in my Draw method: public int Draw(GraphicsDevice device, ICamera camera) { BoundingFrustum frustum = new BoundingFrustum(camera.View * camera.Projection); // Visible count int count = 0; EffectTexture.World = camera.World; EffectTexture.View = camera.View; EffectTexture.Projection = camera.Projection; foreach (EffectPass pass in EffectTexture.CurrentTechnique.Passes) { pass.Apply(); foreach (RenderBoundaries<Ground> render in Boundaries.Where(m => frustum.Contains(m.Box) != ContainmentType.Disjoint)) { // Draw ground count++; } } return count; } When I try adding just one ground, then moving the camera so the ground is out of frame it still returns 1 which means it still gets draw even though it's not within the camera's view. Am I doing something or wrong or can it be because of my Camera? Any ideas why it doesn't work?

• Advantages and disadvantages of building a single page web application

  - by ryanzec

  I'm nearing the end of a prototyping/proof of concept phase for a side project I'm working on, and trying to decide on some larger scale application design decisions. The app is a project management system tailored more towards the agile development process. One of the decisions I need to make is whether or not to go with a traditional multi-page application or a single page application. Currently my prototype is a traditional multi-page setup, however I have been looking at backbone.js to clean up and apply some structure to my Javascript (jQuery) code. It seems like while backbone.js can be used in multi-page applications, it shines more with single page applications. I am trying to come up with a list of advantages and disadvantages of using a single page application design approach. So far I have: Advantages All data has to be available via some sort of API - this is a big advantage for my use case as I want to have an API to my application anyway. Right now about 60-70% of my calls to get/update data are done through a REST API. Doing a single page application will allow me to better test my REST API since the application itself will use it. It also means that as the application grows, the API itself will grow since that is what the application uses; no need to maintain the API as an add-on to the application. More responsive application - since all data loaded after the initial page is kept to a minimum and transmitted in a compact format (like JSON), data requests should generally be faster, and the server will do slightly less processing. Disadvantages Duplication of code - for example, model code. I am going to have to create models both on the server side (PHP in this case) and the client side in Javascript. Business logic in Javascript - I can't give any concrete examples on why this would be bad but it just doesn't feel right to me having business logic in Javascript that anyone can read. Javascript memory leaks - since the page never reloads, Javascript memory leaks can happen, and I would not even know where to begin to debug them. There are also other things that are kind of double edged swords. For example, with single page applications, the data processed for each request can be a lot less since the application will be asking for the minimum data it needs for the particular request, however it also means that there could be a lot more small request to the server. I'm not sure if that is a good or bad thing. What are some of the advantages and disadvantages of single page web applications that I should keep in mind when deciding which way I should go for my project?

• Databases and Beer

  - by Johnm

  It is a bit of a no-brainer: Include the word "beer" in a subject line of an e-mail or blog post title and you can be certain that it will be read. While there are times this practice might be a ploy to increase readership, it is not the case for this blog post. There is inspiration that can be drawn from other industries to which we, as database professionals, can apply in our industry. In this post I will highlight one of my favorite participants of the brewing industry. The Boston Beer Company started in the 1970s in Boston, Massachusetts. Others may be more familiar with this company through their Samuel Adams Boston Lager and other various seasonal beers. I am continually inspired by their commitment to mastery of the brewing process to which they evangelize frequently in their commercials. They also are continually in pursuit of pushing the boundaries of beer as we know it while working within traditional constraints. A recent example of this is their collaboration with Weihenstephan Brewery of Munich, Germany to produce the soon to be released Infinium beer. This beer, while brewed as an ale, is touted as something closer to something like Champaign - all while complying with the Reinheitsgebot. The Reinheitsgebot is also known as the "German Beer Purity Law" which was originated in 1516. This law states that beer is to consist of water, barley, hops and yeast. That's it. Quite a limiting constraint indeed. and yet, The Boston Beer Company pushed forward. Much like the process of brewing, the discipline of database design and architecture is one that is continually in process and driven by the pursuit of mastery. While we do not have purity laws to constrain us, we have many other types: best practices, company policies, government regulations, security and budgets. Through our fellow comrades, we discuss the challenges and constraints in which we operate. We boil down the principles and theories that define our profession. We reassemble these into something that is complementary to the business needs that we must fulfill. As a result, it is not uncommon to see something amazingly innovative in a small business who is pushing the boundaries of their database well beyond its intended state. It is equally common to see innovation in the use of features available in the more advanced features of databases that are found in large businesses. The tag line for The Boston Beer Company is: "Take Pride In Your Beer.", I would like to offer an alternative and say "Take Pride In Your Database." So, As you pour your next Boston Lager into a frosted glass, consider those who spend their lives mastering the craft of brewing and strive to interject their spirit into everything that you do as a database professional. Cheers!

• Stir Trek 2: Iron Man Edition

  Next month (7 May 2010) Ill be presenting at the second annual Stir Trek event in Columbus, Ohio. Stir Trek (so named because last year its themes mixed MIX and the opening of the Star Trek movie) is a very cool local event.  Its a lot of fun to present at and to attend, because of its unique venue: a movie theater.  And whats more, the cost of admission includes a private showing of a new movie (this year: Iron Man 2).  The sessions cover a variety of topics (not just Microsoft), similar to CodeMash.  The event recently sold out, so Im not telling you all of this so that you can go and sign up (though I believe you can get on the waitlist still).  Rather, this is pretty much just an excuse for me to talk about my session as a way to organize my thoughts. Im actually speaking on the same topic as I did last year, but the key difference is that last year the subject of my session was nowhere close to being released, and this year, its RTM (as of last week).  Thats right, the topic is Whats New in ASP.NET 4 how did you guess? Whats New in ASP.NET 4 So, just what *is* new in ASP.NET 4?  Hasnt Microsoft been spending all of their time on Silverlight and MVC the last few years?  Well, actually, no.  There are some pretty cool things that are now available out of the box in ASP.NET 4.  Theres a nice summary of the new features on MSDN.  Here is my super-brief summary: Extensible Output Caching use providers like distributed cache or file system cache Preload Web Applications IIS 7.5 only; avoid the startup tax for your site by preloading it. Permanent (301) Redirects are finally supported by the framework in one line of code, not two. Session State Compression Can speed up session access in a web farm environment.  Test it to see. Web Forms Features several of which mirror ASP.NET MVC advantages (viewstate, control ids) Set Meta Keywords and Description easily Granular and inheritable control over ViewState Support for more recent browsers and devices Routing (introduced in 3.5 SP1) some new features and zero web.config changes required Client ID control makes client manipulation of DOM elements much simpler. Row Selection in Data Controls fixed (id based, not row index based) FormView and ListView enhancements (less markup, more CSS compliant) New QueryExtender control makes filtering data from other Data Source Controls easy More CSS and Accessibility support Reduction of Tables and more control over output for other template controls Dynamic Data enhancements More control templates Support for inheritance in the Data Model New Attributes ASP.NET Chart Control (learn more) Lots of IDE enhancements Web Deploy tool My session will cover many but not all of these features.  Theres only an hour (3pm-4pm), and its right before the prize giveaway and movie showing, so Ill be moving quickly and most likely answering questions off-line via email after the talk. Hope to see you there! Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• Ubuntu won't display netbook's native resolution

  - by Daniel

  FYI: My Netbook model is HP Mini 210-1004sa, which comes with Intel Graphics Media Accelerator 3150, and has a display 10.1" Active Matrix Colour TFT 1024 x 600. I recently removed Windows 7 Starter from my netbook, and replaced it with Ubuntu 12.10. The problem is the OS doesn't seem to recognise the native display resolution of 1024x600 i.e. the bottom bits of Ubuntu is hidden beneath the screen & the only 2 available resolutions are: the default 1024x768 and 800x600. I've also thought about replacing Ubuntu with Lubuntu or Puppy Linux, as the system does run a bit slow, but I can't, as then I won't be able to access the taskbar and application menu which will be hidden beneath the screen. Only Ubuntu with Unity is currently usable, as the Unity Launcher is visible enough. I was able to define a custom resolution 1024x600 using the Q&A: How set my monitor resolution? but when I set that resolution, there appears a black band at the top of the screen and the desktop area is lowered, with bits of it hidden beneath the screen. I tried leaving it at this new resolution and restarting the system to see if the black band would disappear & the display will fit correctly, but it gets reset to 1024x768 at startup and displays following error: Could not apply the stored configuration for monitors none of the selected modes were compatible with the possible modes: Trying modes for CRTC 63 CRTC 63: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 0) CRTC 63: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 0) CRTC 63: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 0) CRTC 63: trying mode 1024x768@60Hz with output at 1024x600@60Hz (pass 1) CRTC 63: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 1) CRTC 63: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 1) CRTC 63: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 1) Trying modes for CRTC 64 CRTC 64: trying mode 1024x768@60Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 0) CRTC 64: trying mode 1024x768@60Hz with output at 1024x600@60Hz (pass 1) CRTC 64: trying mode 800x600@60Hz with output at 1024x600@60Hz (pass 1) CRTC 64: trying mode 800x600@56Hz with output at 1024x600@60Hz (pass 1) CRTC 64: trying mode 640x480@60Hz with output at 1024x600@60Hz (pass 1)

• Arcball 3D camera - how to convert from camera to object coordinates

  - by user38873

  I have checked multiple threads before posting, but i havent been able to figure this one out. Ok so i have been following this tutorial, but im not using glm, ive been implementing everything up until now, like lookat etc. http://en.wikibooks.org/wiki/OpenGL_Programming/Modern_OpenGL_Tutorial_Arcball So i can rotate with the click and drag of the mouse, but when i rotate 90º degrees around Y and then move the mouse upwards or donwwards, it rotates on the wrong axis, this problem is demonstrated on this part of the tutorial An extra trick is converting the rotation axis from camera coordinates to object coordinates. It's useful when the camera and object are placed differently. For instace, if you rotate the object by 90° on the Y axis ("turn its head" to the right), then perform a vertical move with your mouse, you make a rotation on the camera X axis, but it should become a rotation on the Z axis (plane barrel roll) for the object. By converting the axis in object coordinates, the rotation will respect that the user work in camera coordinates (WYSIWYG). To transform from camera to object coordinates, we take the inverse of the MV matrix (from the MVP matrix triplet). What i have to do acording to the tutorial is convert my axis_in_camera_coordinates to object coordinates, and the rotation is done well, but im confused on what matrix i use to do just that. The tutorial talks about converting the axis from camera to object coordinates by using the inverse of the MV. Then it shows these 3 lines of code witch i havent been able to understand. glm::mat3 camera2object = glm::inverse(glm::mat3(transforms[MODE_CAMERA]) * glm::mat3(mesh.object2world)); glm::vec3 axis_in_object_coord = camera2object * axis_in_camera_coord; So what do i aply to my calculated axis?, the inverse of what, i supose the inverse of the model view? So my question is how do you transform camera axis to object axis. Do i apply the inverse of the lookat matrix? My code: if (cur_mx != last_mx || cur_my != last_my) { va = get_arcball_vector(last_mx, last_my); vb = get_arcball_vector( cur_mx, cur_my); angle = acos(min(1.0f, dotProduct(va, vb)))*20; axis_in_camera_coord = crossProduct(va, vb); axis.x = axis_in_camera_coord[0]; axis.y = axis_in_camera_coord[1]; axis.z = axis_in_camera_coord[2]; axis.w = 1.0f; last_mx = cur_mx; last_my = cur_my; } Quaternion q = qFromAngleAxis(angle, axis); Matrix m; qGLMatrix(q,m); vi = mMultiply(m, vi); up = mMultiply(m, up); ViewMatrix = ogLookAt(vi.x, vi.y, vi.z,0,0,0,up.x,up.y,up.z);

To that, I respond: “HTML was never why your site looked good in the first place. It was the CSS.” Now you have an un-stylized theme that uses HTML 5 elements throughout your WordPress site. If you want to learn how to apply CSS to your WordPress blog, you should check out the WordPress codex that pretty much covers everything there is to cover about WordPress development. Now, remember how we noted earlier that your free WordPress.com account wouldn’t take advantage of this technique? That is because, as of the time of this writing, you needed to pay a fee to use custom CSS. Remember now, this only gives you the foundation to create your own HTML 5 WordPress site. There are some HTML 5 themes out there that already look good, and were built using this as the foundation and added some CSS 3 to really spice it up. Looking forward to seeing more HTML 5 WordPress sites! Enjoy developing the future of the web.

• Oracle's Integrated Systems Management and Support Experience

  - by Scott McNeil

  With its recent launch, Oracle Enterprise Manager 11g introduced a new approach to integrated systems management and support. What this means is taking both areas of IT management and vendor support and combining them into one integrated comprehensive and centralized platform. Traditional Ways Under the traditional method, IT operational teams would often focus on running their systems using management tools that weren’t connected to their vendor’s support systems. If you needed support with a product, administrators would often contact the vendor by phone or visit the vendor website for support and then log a service request in order to fix the issues. This method was also very time consuming, as administrators would have to collect their software configurations, operating systems and hardware settings, then manually enter them into an online form or recite them to a support analyst on the phone. For the vendor, they had to analyze all the configuration data to recreate the problem in order to solve it. This approach was very manual, uncoordinated and error-prone where duplication between the customer and vendor frequently occurred. A Better Support Experience By removing the boundaries between support, IT management tools and the customer’s IT infrastructure, Oracle paved the way for a better support experience. This was achieved through integration between Oracle Enterprise Manager 11g and My Oracle Support. Administrators can not only manage their IT infrastructure and applications through Oracle Enterprise Manager’s centralized console but can also receive proactive alerts and patch recommendations right within the console they use day-in-day-out. Having one single source of information saves time and potentially prevents unforeseen problems down the road. All for One, and One for All The first step for you is to allow Oracle Enterprise Manager to upload configuration data into Oracle’s secure configuration repository, where it can be analyzed for potential issues or conflicts for all customers. A fix to a problem encountered by one customer may actually be relevant to many more. The integration between My Oracle Support and Oracle Enterprise Manager allows all customers who may be impacted by the problem to receive a notification about the fix. Once the alert appears in Oracle Enterprise Manager’s console, the administrator can take his/her time to do further investigations using automated workflows provided in Oracle Enterprise Manager to analyze potential conflicts. Finally, administrators can schedule a time to test and automatically apply the fix to all the systems that need it. In the end, this helps customers maintain their service levels without compromise and avoid experiencing unplanned downtime that may result from potential issues or conflicts. This new paradigm of integrated systems management and support helps customers keep their systems secure, compliant, and up-to-date, while eliminating the traditional silos between IT management and vendor support. Oracle’s next generation platform also works hand-in-hand to provide higher quality of service to business users while at the same time making life for administrators less complicated.

• Will polishing my current project be a better learning experience than starting a new one?

  - by Alejandro Cámara

  I started programming many years ago. Now I'm trying to make games. I have read many recommendations to start cloning some well known games like galaga, tetris, arkanoid, etc. I have also read that I should go for the whole game (including menus, sound, score, etc.). Yesterday I finished the first complete version of my arkanoid clone. But it is far from over. I can still work on it for months (I program as a hobby in my free time) implementing a screen resolution switcher, remap of the control keys, power-ups falling from broken bricks, and a huge etc. But I do not want to be forever learning how to clone ONE game. I have the urge to get to the next clone in order to apply some design ideas I have come upon while developing this arkanoid clone (at the same time I am reading the GoF book and much source code from Ludum Dare 21 game contest). So the question is: Should I keep improving the arkanoid clone until it has all the features the original game had? or should I move to the next clone (there are almost infinite games to clone) and start mending the things I did wrong with the previous clone? This can be a very subjective question, so please restrain the answers to the most effective way to learn how to make my own games (not cloning someone ideas). Thank you! CLARIFICATION In order to clarify what I have implemented I make this list: Features implemented: Bouncing capabilities (the ball bounces on walls, on bricks, and on the bar). Sounds when bouncing on bricks and the bar, and when the player wins or loses. Basic title menu (new game and exit only). Also in-game menu and win/lose menus. Only three levels, but the map system is so easy I do not think it will teach me much (am I wrong?). Features not-implemented: Power-ups when breaking the bricks. Complex bricks (with more than one "hit point" and invincible). Better graphics (I am not really good at it). Programming polishing (use more intensively the design patterns). Here's a link to its (minimal) webpage: http://blog.acamara.es/piperine/ I kind of feel ashamed to show it, so please do not hit me too hard :-) My question was related to the not-implemented features. I wondered what was the fastest (optimal) path to learn. 1) implement the not-implemented features in this project which is getting big, or 2) make a new game which probably will teach me those lessons and new ones. ANSWER I choose @ashes999 answer because, in my case, I think I should polish more and try to "ship" the game. I think all the other answers are also important to bear in mind, so if you came here having the same question, before taking a rush decision read all the discussion. Thank you all!

• Simple method for reliably detecting code in text?

  - by Jeff Atwood

  GMail has this feature where it will warn you if you try to send an email that it thinks might have an attachment. Because GMail detected the string see the attached in the email, but no actual attachment, it warns me with an OK / Cancel dialog when I click the Send button. We have a related problem on Stack Overflow. That is, when a user enters a post like this one: my problem is I need to change the database but I don't won't to create a new connection. example: DataSet dsMasterInfo = new DataSet(); Database db = DatabaseFactory.CreateDatabase("ConnectionString"); DbCommand dbCommand = db.GetStoredProcCommand("uspGetMasterName"); This user did not format their code as code! That is, they didn't indent by 4 spaces per Markdown, or use the code button (or the keyboard shortcut ctrl+k) which does that for them. Thus, our system is accreting a lot of edits where people have to go in and manually format code for people that are somehow unable to figure this out. This leads to a lot of bellyaching. We've improved the editor help several times, but short of driving over to the user's house and pressing the correct buttons on their keyboard for them, we're at a loss to see what to do next. That's why we are considering a Google GMail style warning: Did you mean to post code? You wrote stuff that we think looks like code, but you didn't format it as code by indenting 4 spaces, using the toolbar code button or the ctrl+k code formatting command. However, presenting this warning requires us to detect the presence of what we think is unformatted code in a question. What is a simple, semi-reliable way of doing this? Per Markdown, code is always indented by 4 spaces or within backticks, so anything correctly formatted can be discarded from the check immediately. This is only a warning and it will only apply to low-reputation users asking their first questions (or providing their first answers), so some false positives are OK, so long as they are about 5% or less. Questions on Stack Overflow can be in any language, though we can realistically limit our check to, say, the "big ten" languages. Per the tags page that would be C#, Java, PHP, JavaScript, Objective-C, C, C++, Python, Ruby. Use the Stack Overflow creative commons data dump to audit your potential solution (or just pick a few questions in the top 10 tags on Stack Overflow) and see how it does. Pseudocode is fine, but we use c# if you want to be extra friendly. The simpler the better (so long as it works). KISS! If your solution requires us to attempt to compile posts in 10 different compilers, or an army of people to manually train a bayesian inference engine, that's ... not exactly what we had in mind.

• Keybindings for individual letter keys (not modifier-combinations) on a GtkTextView widget (Gtk3 and PyGI)

  - by monotasker

  I've been able to set several keybord shortcuts for a GtkTextView and a GtkTextEntry using the new css provider system. I'm finding, though, that I only seem to be able to establish keybindings for combinations including a modifier key. The widget doesn't respond to any bindings I set up that use: the delete key the escape key individual letter or punctuation keys alone Here's the code where I set up the css provider for the keybindings: #set up style context keys = Gtk.CssProvider() keys.load_from_path(os.path.join(data_path, 'keybindings.css')) #set up style contexts and css providers widgets = {'window': self.window, 'vbox': self.vbox, 'toolbar': self.toolbar, 'search_entry': self.search_entry, 'paned': self.paned, 'notelist_treeview': self.notelist_treeview, 'notelist_window': self.notelist_window, 'notetext_window': self.notetext_window, 'editor': self.editor, 'statusbar': self.statusbar } for l, w in widgets.iteritems(): w.get_style_context().add_provider(keys, Gtk.STYLE_PROVIDER_PRIORITY_USER) Then in keybindings.css this is an example of what works: @binding-set gtk-vi-text-view { bind "<ctrl>b" { "move-cursor" (display-lines, -5, 0) }; /* 5 lines up */ bind "<ctrl>k" { "move-cursor" (display-lines, -1, 0) }; /* down */ bind "<ctrl>j" { "move-cursor" (display-lines, 1, 0) }; /* up */ } Part of what I'm trying to do is just add proper delete-key function to the text widgets (right now the delete key does nothing at all). So if I add a binding like one of these, nothing happens: bind "Delete" { "delete-selection" () }; bind "Delete" { "delete-from-cursor" (chars, 1) }; The other part of what I want to do is more elaborate. I want to set up something like Vim's command and visual modes. So at the moment I'm just playing around with (a) setting the widget to editable=false by hitting the esc key; and (b) using homerow letters to move the cursor (as a proof-of-concept exercise). So far there's no response from the escape key or from the letter keys, even though the bindings work when I apply them to modifier-key combinations. For example, I do this in the css for the text-widget: bind "j" { "move-cursor" (display-lines, 1, 0) }; /* down */ bind "k" { "move-cursor" (display-lines, -1, 0) }; /* up */ bind "l" { "move-cursor" (logical-positions, 1, 0) }; /* right */ bind "h" { "move-cursor" (logical-positions, -1, 0) }; /* left */ but none of these bindings does anything, even if other bindings in the same set are respected. What's especially odd is that the vim-like movement bindings above are respected when I attach them to a GtkTreeView widget for navigating the tree-view options: @binding-set gtk-vi-tree-view { bind "j" { "move-cursor" (display-lines, 1) }; /* selection down */ bind "k" { "move-cursor" (display-lines, -1) }; /* selection up */ } So it seems like there are limitations or overrides of some kind on keybindings for the TextView widget (and for the del key?), but I can't find documentation of anything like that. Are these just things that can't be done with the css providers? If so, what are my alternatives for non-modified keybindings? Thanks.

• How to build a 4x game?

  - by Marco

  I'm trying to study how succefully implement a 4x game. Area of interest: 1) map data: how to store stellars systems (graphs?), how to generate them and so on.. 2) multiplayer: how to organize code in a non graphical server and a client to display it 3) command system: what are patters to catch user and ai decisions and handle them, adding at first "explore" and "colonize" then "combat", "research", "spy" and so on (commands can affect ships, planets, research, etc..) 4) ai system: ai can use commands to expand, upgrade planets and ship I know is a big questions, so help is appreciated :D 1) Map data Best choice is have a graph to model a galaxy. A node is a stellar system and every system have a list of planets. Ship cannot travel outside of predefined paths, like in Ascendancy: http://www.abandonia.com/files/games/221/Ascendancy_2.png Every connection between two stellar systems have a cost, in turns. Generate a galaxy is only a matter of: - dimension: number of stellar systems, - variety: randomize number of planets and types (desertic, earth, etc..), - positions of each stellar system on game space - connections: assure that exist a path between every node, so graph is "connected" (not sure if this a matematically correct term) 2) Multiplayer Game is organized in turns: player 1, player 2, ai1, ai2. Server take care of all data and clients just diplay it and collect data change. Because is a turn game, latency is not a problem :D 3) Command system I would like to design a hierarchy of commands to take care of this aspect: abstract Genericcommand (target) ExploreCommand (Ship) extends genericcommand colonizeCommand (Ship) buildcommand(planet, object) and so on. In my head all this commands are stored in a queue for every planets, ships or reasearch center or spy, and each turn a command is sent to a server to apply command and change data state 4) ai system I don't have any idea about this. Is a big topic and what I want is a simple ai. Something like "expand and fight against everyone". I think about a behaviour tree to control ai moves, so I can develop an ai that try to build ships to expand and then colonize planets, upgrade them throught science and combat enemies. Could be done with a finite state machine too ? any ideas, resources, article are welcome!

• Strange rendering in XNA/Monogame

  - by Gerhman

  I am trying to render G-Code generated for a 3d-printer as the printed product by reading the file as line segments and the drawing cylinders with the diameter of the filament around the segment. I think I have managed to do this part right because the vertex I am sending to the graphics device appear to have been processed correctly. My problem I think lies somewhere in the rendering. What basically happens is that when I start rotating my model in the X or Y axis then it renders perfectly for half of the rotation but then for the other half it has this weird effect where you start seeing through the outer filament into some of the shapes inside. This effect is the strongest with X rotations though. Here is a picture of the part of the rotation that looks correct: And here is one that looks horrible: I am still quite new to XNA and/Monogame and 3d programming as a whole. I have no idea what could possibly be causing this and even less of an idea of what this type of behavior is called. I am guessing this has something to do with rendering so have added the code for that part: protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.Black); basicEffect.World = world; basicEffect.View = view; basicEffect.Projection = projection; basicEffect.VertexColorEnabled = true; basicEffect.EnableDefaultLighting(); GraphicsDevice.SetVertexBuffer(vertexBuffer); RasterizerState rasterizerState = new RasterizerState(); rasterizerState.CullMode = CullMode.CullClockwiseFace; rasterizerState.ScissorTestEnable = true; GraphicsDevice.RasterizerState = rasterizerState; foreach (EffectPass pass in basicEffect.CurrentTechnique.Passes) { pass.Apply(); GraphicsDevice.DrawPrimitives(PrimitiveType.TriangleList, 0, vertexBuffer.VertexCount); } base.Draw(gameTime); } I don't know if it could be because I am shading something that does not really have a texture. I am using this custom vertex declaration I found on some tutorial that allows me to store a vertex with a position, color and normal: public struct VertexPositionColorNormal { public Vector3 Position; public Color Color; public Vector3 Normal; public readonly static VertexDeclaration VertexDeclaration = new VertexDeclaration ( new VertexElement(0, VertexElementFormat.Vector3, VertexElementUsage.Position, 0), new VertexElement(sizeof(float) * 3, VertexElementFormat.Color, VertexElementUsage.Color, 0), new VertexElement(sizeof(float) * 3 + 4, VertexElementFormat.Vector3, VertexElementUsage.Normal, 0) ); } If any of you have ever seen this type of thing please help. Also, if you think that the problem might lay somewhere else in my code then please just request what part you would like to see in the comments section.

• Adding complexity to remove duplicate code

  - by Phil

  I have several classes that all inherit from a generic base class. The base class contains a collection of several objects of type T. Each child class needs to be able to calculate interpolated values from the collection of objects, but since the child classes use different types, the calculation varies a tiny bit from class to class. So far I have copy/pasted my code from class to class and made minor modifications to each. But now I am trying to remove the duplicated code and replace it with one generic interpolation method in my base class. However that is proving to be very difficult, and all the solutions I have thought of seem way too complex. I am starting to think the DRY principle does not apply as much in this kind of situation, but that sounds like blasphemy. How much complexity is too much when trying to remove code duplication? EDIT: The best solution I can come up with goes something like this: Base Class: protected T GetInterpolated(int frame) { var index = SortedFrames.BinarySearch(frame); if (index >= 0) return Data[index]; index = ~index; if (index == 0) return Data[index]; if (index >= Data.Count) return Data[Data.Count - 1]; return GetInterpolatedItem(frame, Data[index - 1], Data[index]); } protected abstract T GetInterpolatedItem(int frame, T lower, T upper); Child class A: public IGpsCoordinate GetInterpolatedCoord(int frame) { ReadData(); return GetInterpolated(frame); } protected override IGpsCoordinate GetInterpolatedItem(int frame, IGpsCoordinate lower, IGpsCoordinate upper) { double ratio = GetInterpolationRatio(frame, lower.Frame, upper.Frame); var x = GetInterpolatedValue(lower.X, upper.X, ratio); var y = GetInterpolatedValue(lower.Y, upper.Y, ratio); var z = GetInterpolatedValue(lower.Z, upper.Z, ratio); return new GpsCoordinate(frame, x, y, z); } Child class B: public double GetMph(int frame) { ReadData(); return GetInterpolated(frame).MilesPerHour; } protected override ISpeed GetInterpolatedItem(int frame, ISpeed lower, ISpeed upper) { var ratio = GetInterpolationRatio(frame, lower.Frame, upper.Frame); var mph = GetInterpolatedValue(lower.MilesPerHour, upper.MilesPerHour, ratio); return new Speed(frame, mph); }

• Finding work as a college student

  - by lightburst

  I'm a 3rd year CS student. I'm currently really, really, bored and tired of cheap school programming(I go to a fairly respectable(albeit not top) university in my country, but, really, it's not MIT) so I've been thinking about getting a part-time dev job for a long while now. I'm not some hotshot programmer or anything, but "Add/Delete XYZ class objects to list" or "Do this web feature/pattern in PHP" does get old after a few semesters. I also only learned(heard?) of programming when I entered college, so the duration of me being in contact with any code is short. I can't really apply as an intern as I have not accumulated the necessary credits yet to do that so I was thinking of selling myself as a part-time dev. I still need to go to school, and don't want to subject myself to living two lives. Plus, I think I'd have better chances considering my lack of things to write on the resume. The only language I know at heart is C (I've written several pointer-oriented stuff on my freshman year, which is apparently pretty leet(for some reason), or so Joel says. That sort of boosted my morale a bit) but I've worked with several other languages only for the sake of course work such as C#/Java/PHP/ASM. My only user-worthy project was a recursive quicksort simulator I wrote for class using GTK+ that used a textbox to output the progress. I also have not taken the compiler theory class yet, or my thesis. All that being said, I wonder if any legitimate software company(big or small) would hire somebody like me considering all that. If there are companies that do accept anybody like me, would I be doing programming or maybe just be a tester or something? Would anybody hire me as a dev at all? I know I don't have much(not even a degree) but what I lack in experience, I compensate with interest? I am less interested in websites and 'management' software(no offense or anything. also, most of the places here ONLY have those), and more into 'process driven'(I'm not sure how to call it) and system software. I have my eyes on a startup that sells basically an extension of Google Drive, but I feel like I'm too 'risky' for them. Oh, I'm also 19 if that means anything. We're not K-12 so kids go to college earlier than in the US.

• Outlying DBAs

  - by steveh99999

  Read an interesting book recently, ‘Outliers – the story of success’ by Malcolm Gladwell. There’s a good synopsis of the book here on wikipedia. I don’t want to write in detailed review of the book, but it’s well worth a read. There were a couple of sections which I thought were possibly relevant to IT professionals and DBAs in particular. Firstly, ‘the 10,000 hour rule’, in this section Gladwell asserts that to be a real ‘elite performer’ takes 10,000 hours of practice. ‘Practice isn’t the thing you do once you’re good, it’s the thing you do that makes you good’.  He gives many interesting examples – the Beatles, Bill Gates etc – but I was wondering could this be applied to DBAs ? If it takes 10,000 hours to be a really elite DBA – how long does that really take ? 8 hours a day makes 1250 days. If we assume that most DBAs work around 230 days a year – then it takes around 5 and a half years to become an elite DBA.   But how much time per day does a DBA spend actually doing DBA work ? Certainly it’s my experience that the more experienced I get as a DBA, the less time I seem to spend actually doing DBA work – ie meetings, change-control meetings, project planning, liasing with other teams, appraisals etc.  Is it more accurate to assume that a DBA spends half their time actually doing ‘real’ DBA work – or is that just my bad luck ?   So, in reality, I’d argue it can take at least 5 1/2 and more likely closer to 10 years to become an elite DBA. Why do I keep receiving CVs for senior DBAs with 2-4 years actual DBA experience ? In the second section I found particularly interesting, Gladwell writes about analysis of plane crashes and the importance of in-cockpit communications. He describes a couple of crashes involving Korean Airlines – where co-pilots were often deferrential to pilots, and unwilling to openly criticise their more senior colleagues or point out errors when things were going badly wrong… There’s a better summary of Gladwell’s concepts on mitigation  here – but to apply this to a DBA role… If you are a DBA and you do not agree with  a decision of one of your superiors, then it’s your duty as a DBA to say what you think is wrong, before it’s too late…  Obviously there’s a fine line between constructive criticism and moaning, but a good senior DBA or manager should be able to take well-researched criticism\debate from a more junior DBA.   Is this really possible ?

• Oracle Gave Me a Chance - ECEMEA Internship Programme

  - by FelixWehmeyer

  My name is Mohammad Raad and I started in the One Year Training program with Oracle on March 1, 2012. I graduated on September 2011 and started searching for a job. Starting your career, as you all know, is hard because some companies see you as a fresh graduate lacking experience and no one is willing to invest in you. I used to check the recruitment websites daily to see if there were openings to apply to, but unfortunately no one wanted to hire a zero year experience fresh graduate. One day I saw Oracle’s 1 year internship program advertised and that was what I needed. I applied but expected nothing to happen because I was used to applying and getting no replies, but they called and that was the start! I had my first interview over the phone and decided to go to Qatar and to continue to search for a job. Two weeks after arriving at Qatar, Oracle called me for a second interview in Lebanon so I booked a ticket on the same day because my interview was the next day I had my interview and went back to Qatar. On January 2012, I heard from Oracle that I was accepted and they choose me for this program, it was a day I will not forget! Starting on 1st March 2012, I was full of energy, willing to do anything to gain experience and prove that I can do it. What really give me a big push is my colleagues’ motivation and support especially from Youssef Halawi, my mentor and Rami Mattar because they believe in me and track my progress day-by-day. At Oracle, I meet customers, attend meetings, demos and presentations, partners’ events and online trainings. Now I’m focusing on a specific product that I really liked and aim to master by the end of my internship. So dear readers wish me good luck! I know that I will get the experience that I want, because from Oracle, a leader in its industry, you have the chance to grab experience as much as you can handle, simply because there are no limits to excellence.
