• Is learning C# as a first language a mistake?

  - by JuniorDeveloper1208

  I know there are similar questions on here, which I've read, but I recently read this post by Joel Spolsky: How can I teach a bright person, with no programming experience, how to program? And it got me thinking about my way of learning and whether it might actually be harmful in the long run. I've dabbled with various languages but C# is my first serious one, I've read "Head First C#" and created a few projects. But after reading the post above I've found it a bit disheartening that I may be going about it all wrong, obviously I respect Joel's opinion which is what has thrown me a bit. I've started reading "Code" as recommended in the reading list and I'm finding it pretty hard going, although enjoyable. I feel like it's taken the shine off of my "noobish hacking about" in Visual Studio. So now I'm unsure as to what path I should take? Should I take a step back and follow Joel's advice and start reading? I guess my main aim is just to become a good programmer, like everyone else, but I don't want to be going into bad practice by learning a .NET language when someone who's opinion I respect thinks that it is harmful. Thoughts?

• Trouble with Collada bones

  - by KyleT

  I have a Collada file with a rigged mesh. I've read the node tags in the library_visual_scenes tag and extracted the matrix for each node and stored everything in a hierarchical bone structure. My Matrix container is "row major", so I'd store the first float of a matrix tag in the 1st row, 1st column, the second in the 1st row, 2nd column, etc. From what I gather this is the Bind Pose Matrix. After that I went through the tag and extracted the float array in the source tag of the skin tag of the controller for the mesh. I stored each matrix from this float array in their corresponding Bone as the Inverse Bind Matrix. I also extracted the bind-shape-matrix and stored it. Now I'd like to draw the skeleton with OpenGL to see if everything is working correctly before I go about skinning. I iterate once over my bones and multiply a bone's Bind Pose Matrix by it's parents and store that. After that I iterate again over the bones and multiply the result of the previous matrix multiplication by the Inverse Bind Matrix and then by the Bind Shape Matrix. The results look something like this: [0.2, 9.2, 5.8, 1.2 ] [4.6, -3.3, -0.2, -0.1 ] [-1.8, 0.2, -4.2, -3.9 ] [0, 0, 0, 1 ] I've had to go to various sources to get the little understanding of Collada I have and books about 3d transform matricies can get pretty intense. I've hit a brick wall and if you could please read through this and see if there is something I'm doing wrong, and how I'd go about getting an X,Y,Z to draw a point for each of these joints once I've calculated the final transform, I'd really appreciate it.

• Why is math taught "backwards"? [closed]

  - by Yorirou

  A friend of mine showed me a pretty practical Java example. It was a riddle. I got excited and quickly solved the problem. After it, he showed me the mathematical explanation of my solution (he proved why is it good), and it was completely clear for me. This seems like natural approach for me: solve problems, and generalize. This is very familiar to me, I do it all the time when I am programming: I write a function. When I have to write a similar function, I generalize the problem, grab the generic parts, and refactor them to a function, and solve the original problems as a specialization of the general function. At the university (or at least where I study), things work backwards. The professors shows just the highest possible level of the solutions ("cryptic" mathematical formulas). My problem is that this is too abstract for me. There is no connection of my previous knowledge (== reality in my sense), so even if I can understand it, I can't really learn it properly. Others are learning these formulas word-by-word, and get good grades, since they can write exactly the same to the test, but this is not an option for me. I am a curious person, I can learn interesting things, but I can't learn just text. My brain is for storing toughts, not strings. There are proofs for the theories, but they are also really hard to understand because of this, and in most of the cases they are omitted. What is the reason for this? I don't understand why is it a good idea to show the really high level of abstraction and then leave the practical connections (or some important ideas / practical motivations) out?

• Should I use OpenGL or DX11 for my game?

  - by Sundareswaran Senthilvel

  I'm planning to write a game from scratch (a BIG Game, for commercial purpose). I'm aware that there are certain compute libraries like OpenCL, AMD APP SDK, C++ AMP as well as DirectCompute - both from MS (NOT interested in CUDA) are available in the market. I'm planning to write the game from the scratch, which includes the following engines... Physics Engine AI Engine Main Game Engine (... and if anything is missed). I'm aware that, there are some free physics engine libraries in the market. Not sure about free AI engine libraries. I'm bit confused in choosing between the OpenCL, AMD APP SDK, and C++ AMP libraries (as already mentioned i'm NOT interested in CUDA). I want my game to be published in Windows/Android/Mac OSX. It means it should be a cross-platform game. I will be having "one source code" that i'll compile for various platforms like Windows/Android/Mac OSX, and any others if i missed. Note: Since I'm NOT a Java guy, kindly do NOT suggest me the Java Language. For Graphics language should i use OpenGL or DirectX 11? I have heard that OpenGL runs on a single core, and not sure of DirectX 11. Between OpenGL and DirectX which one should i follow? or else, are there any other graphics language that i need to start with? I want to make use of the parallelism in GPU as well as CPU.

• Strategies for managing use of types in Python

  - by dave

  I'm a long time programmer in C# but have been coding in Python for the past year. One of the big hurdles for me was the lack of type definitions for variables and parameters. Whereas I totally get the idea of duck typing, I do find it frustrating that I can't tell the type of a variable just by looking at it. This is an issue when you look at someone else's code where they've used ambiguous names for method parameters (see edit below). In a few cases, I've added asserts to ensure parameters comply with an expected type but this goes against the whole duck typing thing. On some methods, I'll document the expected type of parameters (eg: list of user objects), but even this seems to go against the idea of just using an object and let the runtime deal with exceptions. What strategies do you use to avoid typing problems in Python? Edit: Example of the parameter naming issues: If our code base we have a task object (ORM object) and a task_obj object (higher level object that embeds a task). Needless to say, many methods accept a parameter named 'task'. The method might expect a task or a task_obj or some other construct such as a dictionary of task properties - it is not clear. It is them up to be to look at how that parameter is used in order to work out what the method expects.

• FOSS Development: Who develops the OS-specific packages?

  - by achristi

  I have a couple of FOSS projects. They can be a bit of a pain to get running unless you've got dependencies in place already, which I figure is par for the course for FOSS projects. We know that each free operating system out there has its own package management systems. A few of them, such as homebrew on Mac OS or AUR on Arch linux are very friendly to community contributions. What I am wondering is, who exactly is expected to contribute packages? Primarily I am concerned with the case of small or developing projects, since it's pretty standard for the big projects to be put in there by the OS maintainers. From my perspective, it is something of a chicken-egg problem, because your software will not make its way into a package system if it does not have users, and it is less likely to gain users if it is not easy to install and use. For the sake of discussion, let's assume that the software in question is actually legitimately useful. I can see where people could create crapware or spam and that should obviously be kept out of any package system. So, in summary, whose job is this? Is it spammy for a FOSS software dev to put his own work into various OS package repositories?

• Build vs Rebuild

  - by prash

  Build means compile and link only the source files that have changed since the last build, while Rebuild means compile and link all source files regardless of whether they changed or not. Build is the normal thing to do and is faster. Sometimes the versions of project target components can get out of sync and rebuild is necessary to make the build successful. In practice, you never need to Clean. Build or Rebuild Solution builds or rebuilds all projects in the your solution, while Build or Rebuild <project name> builds or rebuilds the StartUp project. To set the StartUp project, right click on the desired project name in the Solution Explorer tab and select Set as StartUp project. The project name now appears in bold. Compile just compiles the source file currently being edited. Useful to quickly check for errors when the rest of your source files are in an incomplete state that would prevent a successful build of the entire project. Ctrl-F7 is the shortcut key for Compile. All source files that have changed are saved when you request a build/rebuild, so you don't have to save them first. When you run your executable (F5 or Ctrl-F5), Visual Studio saves all your changed source files and builds anything that changed, so you don't need to explicitly do those steps every time. This allows for quick "trial and error" debugging. Incidentally, if you like those little Visual Studio keyboard shortcuts, you can download posters of the C# and the VB.Net ones, respectively (I am personally a big fan of using keyboard shortcuts :) ).   Visual Studio 2010 http://www.microsoft.com/downloads/en/details.aspx?FamilyID=92ced922-d505-457a-8c9c-84036160639f   Visual Studio 2005 C#: http://www.microsoft.com/downloads/details.aspx?FamilyID=c15d210d-a926-46a8-a586-31f8a2e576fe&DisplayLang=en VB.NET: http://www.microsoft.com/downloads/details.aspx?FamilyID=6bb41456-9378-4746-b502-b4c5f7182203&DisplayLang=en

• PASS Summit Preconference and Sessions

  - by Davide Mauri

  I’m very pleased to announce that I’ll be delivering a Pre-Conference at PASS Summit 2012. I’ll speak about Business Intelligence again (as I did in 2010) but this time I’ll focus only on Data Warehouse, since it’s big topic even alone. I’ll discuss not only what is a Data Warehouse, how it can be modeled and built, but also how it’s development can be approached using and Agile approach, bringing the experience I gathered in this field. Building the Agile Data Warehouse with SQL Server 2012 http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=2821 I’m sure you’ll like it, especially if you’re starting to create a BI Solution and you’re wondering what is a Data Warehouse, if it is still useful nowadays that everyone talks about Self-Service BI and In-Memory databases, and what’s the correct path to follow in order to have a successful project up and running. Beside this Preconference, I’ll also deliver a regular session, this time related to database administration, monitoring and tuning: DMVs: Power in Your Hands http://www.sqlpass.org/summit/2012/Sessions/SessionDetails.aspx?sid=3204 Here we’ll dive into the most useful DMVs, so that you’ll see how that can help in everyday management in order to discover, understand and optimze you SQL Server installation, from the server itself to the single query. See you there!!!!!

• Java and what to do with it

  - by SterAllures

  I've been browsing through several websites and several topics on this website. Now I'm just a starting programmer and I want to make a good decision. From what I understand is that Java is used alot for server stuff, and web applets but not really for computer applications running on a client, it's also used for Android programming and several other mobiles. I'm really interested in Android programming, I really love to program for mobile devices, in this case Android because I really think it has a lot of potential and I don't like the iPhone. If I want to program on Android I have to learn Java (aside from Mono). but if my decision changes over the next couple of years I don't think Java is the right language to get a job that programs computer applications. I think I get a job where I have to program server stuff, rather than computer applications. That's why I think C# is a good choice. I can program for Windows Phone 7 (I hope that will get big). and I have the feeling C# is more widely used for computer applications. so I think C# is more versatile looking at Mobile programming and computer programming. Or am I totally wrong thinking this?

• Dynamic quadrees

  - by paul424

  recently I come out writing Quadtree for creatures culling in Opendungeons game. Thing is those are moving points and bounding hierarchy will quickly get lost if the quadtree is not rebuild very often. I have several variants, first is to upgrade the leaf position , every time creature move is requested. ( note if I would need collision detection anyway, so this might be necessery anyway). Second would be making leafs enough large , that the creature would sure stay inside it's bounding box ( due to its speed limit). The partition of a plane in quadtree is always fixed ( modulo the hierarchical unions of some parts) . For creatures close to the center of the plane , there would be no way of keeping it but inside one big leaf, besides this brokes the invariant that each point can be put into any small area as desired. So on the second thought could I use several quadrees ? Each would have its "coordinate axis XY" somwhere shifted ? Before I start playing with this maybe some other space diving structure would suit me better, unfortunetly wiki does not compare it's execution time : http://en.wikipedia.org/wiki/Grid_%28spatial_index%29#See_also

• The Start of a Blog

  - by dbradley

  So, here's my new blog up and running, who am I and what am I planning to write here?First off - here's a little about me:I'm a recent graduate from university (coming up to a year ago since I finished) studying Software Engineering on a four year course where the third year was an industrial placement. During the industrial placement I went to work for a company called Adfero in a "Technical Consultant" role as well as a junior "Information Systems Developer". Once I completed my placement I went back to complete my final year but also continued in my developer role 2/3 days a week with the company.Working part time while at uni always seems like a great idea until you get half way through the year. For me the problem was not so much having a lack of time, but rather a lack of interest in the course content having got a chance at working on real projects in a live environment. Most people who have been graduated a little while also find this - when looking back at uni work, it seem to be much more trivial from a problem solving point of view which I found to be true and I found key to uni work to actually be your ability to prove though how you talk about something that you comprehensively understand the basics.After completing uni I then returned full time to Adfero purely in the developer role which is where I've now been for almost a year and have now also taken on the title of "Information Systems Architect" where I'm working on some of the more high level design problems within the products.What I'm wanting to share on this blog is some of the interesting things I've learnt myself over the last year, the things they don't teach you in uni and pretty much anything else I find interesting! My personal favorite areas are text indexing, search and particularly good software engineering design - good design combined with good code makes the first step towards a well-written, maintainable piece of software.Hopefully I'll also be able to share a few of the products I've worked on, the mistake I've made and the software problems I've inherited from previous developers and had to heavily re-factor.

• The Home Stretch: NetBeans IDE 7.1 Release Candidate

  - by TinuA

  The first release candidate build of NetBeans IDE 7.1 is live and available for download, which means the big release (GA) is expected any day soon.NetBeans IDE 7.1 delivers support for JavaFX 2.0, enabling the full compile, debug and profile development cycle for JavaFX 2.0 applications and keeping developers in sync with the latest from the Java platform. Beyond JavaFX support, 7.1 also provides significant Swing GUI Builder enhancements, CSS3 support, and visual debugging tools for JavaFX and Swing user interfaces. And Git--a much anticipated featured--has been integrated into the IDE."The entire NetBeans team is tremendously excited about this release, which provides developers with more state-of-the-art tools for building front-end clients," says NetBeans Engineering Director John Jullion-Ceccarelli. "Whether you are doing JavaFX, HTML5, Swing, or JSF, NetBeans 7.1 will let you quickly and easily develop great-looking and full-featured clients for your Java or PHP-based applications."But there's one more task to check off before the general availability: The NetBeans team has launched a Community Acceptance Survey to get user feedback about the release candidate. Download the RC build, test it and take the survey to let the team know if NetBeans IDE 7.1 is ready for its debut!

• Is there a common programming term for the problems of adding features to an already-featureful program?

  - by Jeremy Friesner

  I'm looking for a commonly used programming term to describe a software-engineering phenomenon, which (for lack of a better way to describe it) I'll illustrate first with a couple of examples-by-analogy: Scenario 1: We want to build/extend a subway system on the outskirts of a small town in Wyoming. There are the usual subway-problems to solve, of course (hiring the right construction company, choosing the best route, buying the subway cars), but other than that it's pretty straightforward to implement the system because there aren't a huge number of constraints to satisfy. Scenario 2: Same as above, except now we need to build/extend the subway system in downtown Los Angeles. Here we face all of the problems we did in case (1), but also additional problems -- most of the applicable space is already in use, and has a vocal constituency which will protest loudly if we inconvenience them by repurposing, redesigning, or otherwise modifying the infrastructure that they rely on. Because of this, extensions to the system happen either very slowly and expensively, or they don't happen at all. I sometimes see a similar pattern with software development -- adding a new feature to a small/simple program is straightforward, but as the program grows, adding further new features becomes more and more difficult, if only because it is difficult to integrate the new feature without adversely affecting any of the large number of existing use-cases or user-constituencies. (even with a robust, adaptable program design, you run into the problem of the user interface becoming so elaborate that the program becomes difficult to learn or use) Is there a term for this phenomenon?

• Install a i386 printer driver into an amd64 distribution or how can I find a good printer based on features?

  - by Yanick Rochon

  Hi, I just bought a Lexmark Interpret S408 all-in-one printer. The box said that it supported Ubuntu 8.04, but I told myself it should work with Lucid... well no. The only driver I have found is for i386 while I have a amd64 image installed; the architecture is incompatible. So, the quesiton is : Is it possible to install that driver anyway, somehow? Or do I need to take that printer back to the store and buy another one? If the latter is the only alternative, I need a printer that has wireless connection capability can do color printing is of good price (less than $200 CAD) Thank you for your answers, help, and tips. ** UPDATE ** The driver was given in the form of deb package (for Debian distributions) and I managed to extract the actual deb package driver out of the install program. I ran sudo dpkg -i --force-all lexmark-inkjet-09-driver-1.5-1.i386.deb and the driver installed, and I was able to print something out. But that pretty much ends there; I cannot access anymore of the printer settings, etc. (i.g. scanner, fax, wifi settings, etc.) I should suffice for now as I'm satisfied with the printer's features (and size, and prince), but if I could have a full-linux-supported printer like that one, I would return this one in exchange for the other.

• Video freezes when larger than a certain size

  - by Poyan

  I have a weird problem playing video files. I have a fairly new (a few years old) graphic card that should and has played up to 1080p video files without much a lot of trouble. I seem to be having a weird issue where the video plays back fine if the window is below a certain size, but as soon as the windowsize increases, the picture freezes. The audio still plays. Usually this is mitigated by killing som applications. Especially GTK (?) apps seem to cause this lag, like having a Nautilus window open usually triggers this error for me. With hardware rendering I get the error regardless of application. I have tried enabling software rendering in VLC and that eliminates the problem (but I get other problems using software rendering, so I've avoided it). I know this is pretty fuzzy, but I'm not sure how to approach this problem. Do you have any idea? EDIT: Some more information. I have the correct and latest drivers installed. My graphics card is a Nvidia 7600 GT.

• Does F# kill C++?

  - by MarkPearl

  Okay, so the title may be a little misleading… but I am currently travelling and so have had very little time and access to resources to do much fsharping – this has meant that I am right now missing my favourite new language. I was interested to see this post on Stack Overflow this evening concerning the performance of the F# language. The person posing the question asked 8 key points about the F# language, namely… How well does it do floating-point? Does it allow vector instructions How friendly is it towards optimizing compilers? How big a memory foot print does it have? Does it allow fine-grained control over memory locality? Does it have capacity for distributed memory processors, for example Cray? What features does it have that may be of interest to computational science where heavy number processing is involved? Are there actual scientific computing implementations that use it? Now, I don’t have much time to look into a decent response and to be honest I don’t know half of the answers to what he is asking, but it was interesting to see what was put up as an answer so far and would be interesting to get other peoples feedback on these questions if they know of anything other than what has been covered in the answer section already.

• What technical details should a programmer of a web application consider before making the site public?

  - by Joel Coehoorn

  What things should a programmer implementing the technical details of a web application consider before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also, I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification.

• How do I draw a dotted or dashed line?

  - by Gagege

  I'm trying to draw a dashed or dotted line by placing individual segments(dashes) along a path and then separating them. The only algorithm I could come up with for this gave me a dash length that was variable based on the angle of the line. Like this: private function createDashedLine(fromX:Float, fromY:Float, toX:Float, toY:Float):Sprite { var line = new Sprite(); var currentX = fromX; var currentY = fromY; var addX = (toX - fromX) * 0.0075; var addY = (toY - fromY) * 0.0075; line.graphics.lineStyle(1, 0xFFFFFF); var count = 0; // while line is not complete while (!lineAtDestination(fromX, fromY, toX, toY, currentX, currentY)) { /// move line draw cursor to beginning of next dash line.graphics.moveTo(currentX, currentY); // if dash is even if (count % 2 == 0) { // draw the dash line.graphics.lineTo(currentX + addX, currentY + addY); } // add next dash's length to current cursor position currentX += addX; currentY += addY; count++; } return line; } This just happens to be written in Haxe, but the solution should be language neutral. What I would like is for the dash length to be the same no matter what angle the line is. As is, it's just adding 75 thousandths of the line length to the x and y, so if the line is and a 45 degree angle you get pretty much a solid line. If the line is at something shallow like 85 degrees then you get a nice looking dashed line. So, the dash length is variable, and I don't want that. How would I make a function that I can pass a "dash length" into and get that length of dash, no matter what the angle is? If you need to completely disregard my code, be my guest. I'm sure there's a better solution.

• Need efficient way to keep enemy from getting hit multiple times by same source

  - by TenFour04

  My game's a simple 2D one, but this probably applies to many types of scenarios. Suppose my player has a sword, or a gun that shoots a projectile that can pass through and hit multiple enemies. While the sword is swinging, there is a duration where I am checking for the sword making contact with any enemy on every frame. But once an enemy is hit by that sword, I don't want him to continue getting hit over and over as the sword follows through. (I do want the sword to continue checking whether it is hitting other enemies.) I've thought of a couple different approaches (below), but they don't seem like good ones to me. I'm looking for a way that doesn't force cross-referencing (I don't want the enemy to have to send a message back to the sword/projectile). And I'd like to avoid generating/resetting multiple array lists with every attack. Each time the sword swings it generates a unique id (maybe by just incrementing a global static long). Every enemy keeps a list of id's of swipes or projectiles that have already hit them, so the enemy knows not to get hurt by something multiple times. Downside is that every enemy may have a big list to compare to. So projectiles and sword swipes would have to broadcast their end-of-life to all enemies and cause a search and remove on every enemy's array list. Seems kind of slow. Each sword swipe or projectile keeps its own list of enemies that it has already hit so it knows not to apply damage. Downsides: Have to generate a new list (probably pull from a pool and clear one) every time a sword is swung or a projectile shot. Also, this breaks down modularity, because now the sword has to send a message to the enemy, and the enemy has to send a message back to the sword. Seems to me that two-way streets like this are a great way to create very difficult-to-find bugs.

• Managing many draw calls for dynamic objects

  - by codetiger

  We are developing a game (cross-platform) using Irrlicht. The game has many (around 200 - 500) dynamic objects flying around during the game. Most of these objects are static mesh and build from 20 - 50 unique Meshes. We created seperate scenenodes for each object and referring its mesh instance. But the output was very much unexpected. Menu screen: (150 tris - Just to show you the full speed rendering performance of 2 test computers) a) NVidia Quadro FX 3800 with 1GB: 1600 FPS DirectX and 2600 FPS on OpenGL b) Mac Mini with Geforce 9400M 256mb: 260 FPS in OpenGL Now inside the game in a test level: (160 dynamic objects counting around 10K tris): a) NVidia Quadro FX 3800 with 1GB: 45 FPS DirectX and 50 FPS on OpenGL b) Mac Mini with Geforce 9400M 256mb: 45 FPS in OpenGL Obviously we don't have the option of mesh batch rendering as most of the objects are dynamic. And the one big static terrain is already in single mesh buffer. To add more information, we use one 2048 png for texture for most of the dynamic objects. And our collision detection hardly and other calculations hardly make any impact on FPS. So we understood its the draw calls we make that eats up all FPS. Is there a way we can optimize the rendering, or are we missing something?

• At the end of my rope

  - by hvgotcodes

  I am a contractor to a big company. Currently, there are three developers on the project, myself included. The problem is the other 2 developers don't really get it. By "it" i mean the following: They don't understand the best practices for the technology we are using. After 6 months of me and others giving them examples there are terrible anti-patterns being used. They are "copy and paste" programmers that produce primarily spaghetti code. They constantly break things, implementing changes but not doing a basic smoke test to see if all is good They refuse/rarely to ask for code-reviews. They refuse/rarely even do basic things like formatting code. No documentation on any classes (jsdocs) Afraid to delete code that doesn't do anything Leave commented code blocks everywhere even though we have version control. I find myself getting more and more frustrated as I format others code, fix bugs, discover functionality that is broken, and create abstractions to remove the spaghetti. I really don't know what to do. I try not to get to frustrated, but it's just a mess. I like these people as people, but I feel like the coding situation is so bad that I could move faster if they simply browsed the web all day. Would it be out of line to ask our manager to review the others svn commit access; commits can only be done after a review by someone who is knowledgeable in what we are doing? As a contractor, I'm not sure if that's the best move. Is there a subtle/not so subtle way of making it clear how many things I am fixing?

• IRC News from #netbeans on FreeNode

  - by Geertjan

  I joined the #netbeans channel on FreeNode last week and the discussions there are really great. It's so cool to not have the endless back and forth of an e-mail exchange. Instead, you can hammer out a complete solution to a problem while chatting live in the channel. A case in point was yesterday, when someone named 'charmeleon' wanted to create a NetBeans Platform based application that includes the "image" module from the NetBeans IDE sources. That way, he'd have a starting point for his own image-oriented application, since he'd not only have the NetBeans Platform, but also the sources of the "image" module. Had we been communicating via e-mail, it would have taken weeks, at least, to come to a solution. Instead, we hashed it out together live, including some very specific problems that would have been hard to communicate about via e-mail. In the end, I made a movie showing exactly the scenario that charmeleon was interested in: And, right now, in the #netbeans channel, charmeleon said: "NetBeans RCP feels like cheating once you start getting over the hump." I'm sure the fact that the hump was handled within a few hours of chatting on irc is a big contributor to that impression.

• how does HDR work?

  - by dotminic

  I'm trying to understand what HDR is and how it works. I understand the basic concepts and have an slight idea of how it is implemented with D3D/hlsl. However it's still pretty foggy. Say I'm rendering a sphere with a texture of the earth and a small point list of vertices to act as stars, how would I render this in HDR ? Here are a few things I'm confused about: I'm guessing, I can't use just any basic image format for the texture as the values would be limited to [0, 255] and clamped to [0, 1] in a shader. Same goes for the back buffer, I take it the format needs to be a float point format ? What are the other steps involved ? Surely there has to be more than just using floating point formats to render to a render target and then apply some bloom as a post process ? (considering the output will be 8bpp anyway) Basically, what are the steps for HDR ? How does it work ? I can't seem to find any good papers / articles that describe the process, other than this one, but it seems to skim over the basics a little, so it's confusing.
