• 12.04 No Sound - ALC888 / Radeon 3200HD

  - by Ross

  Evening all. I have a MSI U230 netbook, MV40 processor, 4Gb RAM with integrated ATI Radeon 3200HD grahics & an ALC888 codec integrated soundcard. It has HDMI out as well. I've tried a few distro's and have been around linux for a short time. I reckon I've settled on Ubuntu 12.04 (32bit) due to it doing pretty much everything I want it to. I'm working with a fresh install right now. I recently re-installed when I was going in circles trying to solve my problem before. I install Ubuntu and it works, except for the sound. I have tried things like reinstalling Alsa, editing my asound.conf file, installing HDA Verb and a few other things. Its at the point where I need to ask for help... Some outputs: ross@ross:~$ aplay -l ** List of PLAYBACK Hardware Devices ** card 0: SB [HDA ATI SB], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 ross@ross:~$ uname -r 3.2.0-34-generic-pae ross@ross:~$ lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780M/RS780MN [Mobility Radeon HD 3200 Graphics] ross@ross:~$ lspci | grep Audio 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) 01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS780 HDMI Audio [Radeon HD 3000-3300 Series] Added options snd-hda-intel position_fix=1 to alsa-base.conf file Unmuted all in alsamixer Can anyone suggest anything more?

• IIS cache control header settings

  - by a_m0d

  I'm currently working on a website that is accessed over https. We have recently come across a problem where we are unable to view .pdf files or any other type of file that is sent as an attachment (Content-Disposition:attachment). According to Microsoft Knowledge Base this is due to the fact that Cache-Control is set to no-cache. However, we have a requirement that all pages be fully reloaded every time they are visited, so we have disabled caching on all pages (through our ASP code, not through IIS settings). However, I have made a special case of this one page that shows the attachment, and it now returns a header with Cache-Control:private and the expiry set to 1 minute in the future. This works fine when I test it on my local machine, using https. However, when I deploy it to our test server and try it, the response headers still return Cache-Control:no-cache. There is no firewall or anything between me and the server, so IIS itself must be adding these headers and replacing mine. I have no idea why it would do this, and it doesn't really make any sense, but it seems to be the only option at the moment (I haven't yet found any other place in the code that will change the cache headers). Can anyone point me to a possible place where IIS might be setting these header values?

• Leveraging Code in Ever Bigger Games

  - by ashes999

  Summary: The same way that I continually build complex engines and libraries within a single platform and technology to allow me to build increasingly bigger and better games, how to continue this when development crosses into different platforms? If I switch platforms, how do I leverage past code and experiences? Games are hard to build. Big games are even harder to build. I've decided that to be able to make big games, I need to start building smaller games, and building up an asset base of code, assets (graphics, sounds), tools, and most importantly, game engines, so that I can eventually get there. One game at a time. Let me give an analogy. To build an MMO 3D RPG, I would approach this by building and releasing small games with increasingly more features. This could entail, for example: A simple 2D game A tile-based game A game with RPG elements (items, equipment, monsters, battle) A full-fledged RPG A 3D RPG The problem now is if I have to change platforms or tools, I don't know how to leverage past code-bases (and experience) to start with a mature product. Right now, I'm writing Silverlight (FlatRedBall) games. Let's say I stick with this for ten years, and then suddenly decide to write a PS6 game, which is in a different programming language entirely. Granted, I have ten years of game-development experience (and correspondingly ten years of professional software development experience from my day job) to back me up. But I would still like some way to transplant that 2D RPG engine into the new programming language, or else leverage it somehow. Is this even possible? What are my options?

• Masters or Second Bachelors Degree..or neither

  - by drD

  I have a degree in Business Administration, because at the time I didn't know what I wanted to do. I have been interested in programming for the past 2 years and have taken some action to self-teach. My experience/ knowledge base is limited to the following: -Read Kochan's Programming in C -Read IOS and Objective-C from the Big Nerd Ranch series -Obtained a C++ at NYU - thought it would be a good way to start to get a grasp on OO & design I would like to continue developing my skills, but most of all, re-orient how I am perceived as a professional. I am fully aware of how much a novice to this subject and would greatly appreciate any guidance anyone could give me. I currently have a job so full-time is not an option My goal is to become a software/ applications developer My questions are: -Should i take up a second bachelors in computer science? or a masters? or continue taking professional certificate programs (how are these viewed?) -If masters in computer science, would that make sense, if I dont have the formal foundation? (being a chief without ever being an Indian) -General advice for a novice to develop skill Thank You in advanced for helping me out.

• Developing Ext JS Charts in NetBeans IDE

  - by Geertjan

  I took my first tentative steps into the world of Ext JS charts today, in NetBeans IDE 7.4. Click to enlarge the image. I will make a screencast soon showing how charts such as the above can be created with NetBeans IDE and Ext JS. Setting up Ext JS is easy in NetBeans IDE because there's a JavaScript library browser, by means of which I can browse for the Ext JS libraries that I need and then NetBeans IDE sets up the project for me. The JavaScript code shown above comes directly from here: http://www.quizzpot.com/courses/learning-ext-js-3/articles/chart-series The index.html is as follows: <html> <head> <title>TODO supply a title</title> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width"> <link rel="stylesheet" href="js/libs/extjs/resources/css/ext-all.css"/> <script src="js/libs/ext-core/ext-core.js"></script> <script src="js/libs/extjs/adapter/ext/ext-base-debug.js"></script> <script src="js/libs/extjs/ext-all-debug.js"></script> <script src="app.js"></script> </head> <body> </body> </html> More info on Ext JS: http://docs.sencha.com/extjs/4.1.3/ By the way, quite a few other articles are out there on Ext JS and NetBeans IDE, such as these, which I will be learning from during the coming days: http://netbeans.dzone.com/extjs-rest-netbeans http://netbeans.dzone.com/articles/create-your-first-extjs-4 http://netbeans.dzone.com/articles/mixing-extjs-json-p-and-java

• SAP or Navision? Career Path

  - by codebased

  This could be tricky to ask; I may or may not ask this question here but I thought to give it a try. I've been in Software Industry since 2002 and now it has been a time that I'm at Senior level where I normally code, lead and define the architect; giving technical solutions to the management is one of my asset that I've earned during my services. Now it is the time to define the road map for the future, $$$. I am not in favor of Project Management roles. I've been thinking of going through the ERP and my current company does provide me an option to go for Navision/ Microsoft Dynamics. They are currently on 4.0 but they are planning to move for 2009 and also to build one of their own plug-in. Indeed the option is good because Microsoft is trying to accomplish the market for Dynamics products. However, they have less success in Australia. Now, Another option is with SAP where person can go with 200 K $ a year. Where as I'd doubt that if the same kind of growth, financial, is available for Microsoft geek. What is your opinion on Navision or SAP? If I try to completely move to SAP it could be bit challenging as market will consider me a fresher. However the return is quite good. Where in case of Microsoft, I think technology changes so fast that there is a less chance to grow in, within, the same experience; in other word, if any new framework comes in .net then market look for that person who knows this new framework and not .net But in case of SAP, where the base remain same and chances are to grab more money from the market. What would you do if you were me? In stackoverflow - Navision questions are 20+ where in SAP 200+///?? :-)

• how do I write a functional spec quickly and efficiently

  - by giddy

  So I just read some fabulous articles by Joel on specs here. (Was written in 2000!!) I read all 4 parts, but Im looking for some methodical approaches to writing my specs. Im the only lonely dev, working on this fairly complicated app (or family of apps) for a very well known finance company. I've never made something this serious, I started out writing something like a bad spec, an overview of some sorts, and it has wasted a LOT of my time. Ive also made 3 mockup-kinda-thingies for my client so I have a good understanding of what they want. Also released a preview (a throw away working app with the most basic workflow), and Ive only written and tested some of the very core/base systems. I think the mistake Ive been making so far is not writing a detailed spec, so Im getting to it now. So the whole thing comprises of An MVC website (for admins & data viewing) 2 Silverlight modules (For 2 specific tasks) 1 Desktop Application Im totally short on time, resources and need to get this done quick, also, need to make sure these guys read it up equally quick and painlessly. So how do I go about it, Im looking for any tips, any real world stuff, how do you guys usually do it? Do you make a mock screenie of every dialog/form/page? Im thinking of making a dummy asp.net web forms project, then filling in html files in folders and making it look like my mvc url structure. Then having a section in the spec for the website and write up a page for every URL Ive got with a screenie. For my win forms app, Ive made somewhat of a demo Win Form project, would I then put in a dialog or stucture everything as I would in the real app and then screen shot it?

• Applying effects to an existing program that uses BasicEffect

  - by Fibericon

  Using the finished product from the tutorial here. Is it possible to apply the grayscale effect from here: Making entire scene fade to grayscale Or would you basically have to rewrite everything? EDIT: It's doing something now, but the whole grayscale seems extremely blue. It's like I'm looking at it through dark blue sunglasses. Here's my draw function: protected override void Draw(GameTime gameTime) { device.SetRenderTarget(renderTarget); graphics.GraphicsDevice.Clear(Color.CornflowerBlue); //Drawing models, bullets, etc. device.SetRenderTarget(null); spriteBatch.Begin(0, BlendState.Additive, SamplerState.PointWrap, DepthStencilState.Default, RasterizerState.CullNone, grayScale); Texture2D temp = (Texture2D)renderTarget; grayScale.Parameters["coloredTexture"].SetValue(temp); grayScale.CurrentTechnique = grayScale.Techniques["Grayscale"]; foreach (EffectPass pass in grayScale.CurrentTechnique.Passes) { pass.Apply(); } spriteBatch.Draw(temp, new Vector2(GraphicsDevice.PresentationParameters.BackBufferWidth/2, GraphicsDevice.PresentationParameters.BackBufferHeight/2), null, Color.White, 0f, new Vector2(renderTarget.Width/2, renderTarget.Height/2), 1.0f, SpriteEffects.None, 0f); spriteBatch.End(); base.Draw(gameTime); } Another edit: figured out what I was doing wrong. I have Blendstate.Additive in the spriteBatch.Draw() call. It should be Blendstate.Opaque, or it literally tries to add the blank blue image to the grayscale image.

• .NET development on Macs

  - by Jeff

  I posted the “exciting” conclusion of my laptop trade-ins and issues on my personal blog. The links, in chronological order, are posted below. While those posts have all of the details about performance and software used, I wanted to comment on why I like using Macs in the first place. It started in 2006 when Apple released the first Intel-based Mac. As someone with a professional video past, I had been using Macs on and off since college (1995 graduate), so I was never terribly religious about any particular platform. I’m still not, but until recently, it was staggering how crappy PC’s were. They were all plastic, disposable, commodity crap. I could never justify buying a PowerBook because I was a Microsoft stack guy. When Apple went Intel, they removed that barrier. They also didn’t screw around with selling to the low end (though the plastic MacBooks bordered on that), so even the base machines were pretty well equipped. Every Mac I’ve had, I’ve used for three years. Other than that first one, I’ve also sold each one, for quite a bit of money. Things have changed quite a bit, mostly within the last year. I’m actually relieved, because Apple needs competition at the high end. Other manufacturers are finally understanding the importance of industrial design. For me, I’ll stick with Macs for now, because I’m invested in OS X apps like Aperture and the Mac versions of Adobe products. As a Microsoft developer, it doesn’t even matter though… with Parallels, I Cmd-Tab and I’m in Windows. So after three and a half years with a wonderful 17” MBP and upgraded SSD, it was time to get something lighter and smaller (traveling light is critical with a toddler), and I eventually ended up with a 13” MacBook Air, with the i7 and 8 gig upgrades, and I love it. At home I “dock” it to a Thunderbolt Display.

• Custom Session Management using HashTable

  - by kaleidoscope

  ASP.NET session state lets you associate a server-side string or object dictionary containing state data with a particular HTTP client session. A session is defined as a series of requests issued by the same client within a certain period of time, and is managed by associating a session ID with each unique client. The ID is supplied by the client on each request, either in a cookie or as a special fragment of the request URL. The session data is stored on the server side in one of the supported session state stores, which include in-process memory, SQL Server™ database, and the ASP.NET State Server service. The latter two modes enable session state to be shared among multiple Web servers on a Web farm and do not require server affinity. Implement Custom session Handler you need to follow following process : 1. Create class library which will inherit from  SessionStateStoreProviderBase abstract Class. 2. Implement all abstract Method in your base class. 3.Change Mode of session to “Custom” in web.config file and provide Provider as your Namespace with classname. <sessionState mode=”Custom” customProvider=”Namespace.classname”> <Providers> <add name=”Name” type=”Namespace.classname”> </sessionstate> For more Details Please refer following links :   http://msdn.microsoft.com/en-us/magazine/cc163730.aspx http://msdn.microsoft.com/en-us/library/system.web.sessionstate.sessionstatestoreproviderbase.aspx - Chandraprakash, S Technorati Tags: Chandraprakash,Session state Managment

• Inheriting projects - General Rules?

  - by pspahn

  This is an area of discussion I have long been curious about, but overall, I generally lack the experience to give myself an answer that I would fully trust. We've all been there, a new client shows up with a half-complete project they are looking to finish and launch. For whatever reason, they fired their previous developer, and it's now up to you to save the day. I am just finishing up a code review for a new client, and in my estimation is would be better to scrap what the previous developers built since and start from scratch. There's a ton of reasons why I am leaning toward this way, but it still makes me nervous since the client isn't going to want to hear "those last guys built you a big turd, and I can either polish it, or throw it in the trash". What are your general rules for accepting these projects? How do you determine whether it will be better to start from scratch or continue with the existing code base? What other extra steps might you take to help control client expectations, since the previous developer may have inflated those expectations beyond a reasonable level? Any other general advice?

• OOP concept: is it possible to update the class of an instantiated object?

  - by Federico

  I am trying to write a simple program that should allow a user to save and display sets of heterogeneous, but somehow related data. For clarity sake, I will use a representative example of vehicles. The program flow is like this: The program creates a Garage object, which is basically a class that can contain a list of vehicles objects Then the users creates Vehicles objects, these Vehicles each have a property, lets say License Plate Nr. Once created, the Vehicle object get added to a list within the Garage object --Later on--, the user can specify that a given Vehicle object is in fact a Car object or a Truck object (thus giving access to some specific attributes such as Number of seats for the Car, or Cargo weight for the truck) At first sight, this might look like an OOP textbook question involving a base class and inheritance, but the problem is more subtle because at the object creation time (and until the user decides to give more info), the computer doesn't know the exact Vehicle type. Hence my question: how would you proceed to implement this program flow? Is OOP the way to go? Just to give an initial answer, here is what I've came up until now. There is only one Vehicle class and the various properties/values are handled by the main program (not the class) through a dictionary. However, I'm pretty sure that there must be a more elegant solution (I'm developing using VB.net): Public Class Garage Public GarageAdress As String Private _ListGarageVehicles As New List(Of Vehicles) Public Sub AddVehicle(Vehicle As Vehicles) _ListGarageVehicles.Add(Vehicle) End Sub End Class Public Class Vehicles Public LicensePlateNumber As String Public Enum VehicleTypes Generic = 0 Car = 1 Truck = 2 End Enum Public VehicleType As VehicleTypes Public DictVehicleProperties As New Dictionary(Of String, String) End Class NOTE that in the example above the public/private modifiers do not necessarily reflect the original code

  So I've always been under the impression that doing work on the GPU is always faster than on the CPU. Because of this, in OpenGL, I usually try to do intensive tasks in shaders so they get the speed boost from the GPU. However, now I'm starting to realize that some things simply work better on the CPU and actually perform worse on the GPU (particularly when a geometry shader is involved). For example, in a recent project I did involving procedurally generated terrain, I tried passing a grid of single triangles into a geometry shader, and tesselated each of these triangles into quads with 400 vertices whose height was determined by a noise function. This worked fine, and looked great, but easily maxed out the GPU with only 25 base triangles and caused a very slow framerate. I then discovered that tesselating on the CPU instead, and setting the height (using noise function) in the vertex shader was actually faster! This prompted me to question the benefits of using the GPU as much as possible... So, I was wondering if someone could describe the general pros and cons of using the GPU vs CPU for intensive graphics tasks. I know this mainly comes down to what your trying to achieve, so if necessary, use the above scenario to discuss why the "CPU + vertex shader" was actually faster than doing everything in the geometry shader on the GPU. It's possible my hardware (newest macbook pro) isn't optomized well for the geometry shader (thus causing the slow framerate). Also, I read that the vertex shader is very good with parallelism, and would love a quick explanation of how this may have played a role in speeding up my procedural terrain. Any info/advice about CPU/GPU/shaders would be awesome!

• How to design highly scalable web services in Java?

  - by Kshitiz Sharma

  I am creating some Web Services that would have 2000 concurrent users. The services are offered for free and are hence expected to get a large user base. In the future it may be required to scale up to 50,000 users. There are already a few other questions that address the issue like - Building highly scalable web services However my requirements differ from the question above. For example - My application does not have a user interface, so images, CSS, javascript are not an issue. It is in Java so suggestions like using HipHop to translate PHP to native code are useless. Hence I decided to ask my question separately. This is my project setup - Rest based Web services using Apache CXF Hibernate 3.0 (With relevant optimizations like lazy loading and custom HQL for tune up) Tomcat 6.0 MySql 5.5 My questions are - Are there alternatives to Mysql that offer better performance for what I'm trying to do? What are some general things to abide by in order to scale a Java based web application? I am thinking of putting my Application in two tomcat instances with httpd redirecting the request to appropriate tomcat on basis of load. Is this the right approach? Separate tomcat instances can help but then database becomes the bottleneck since both applications access the same database? I am a programmer not a Db Admin, how difficult would it be to cluster a Mysql database (or, to cluster whatever database offered as an alternative to 1)? How effective are caching solutions like EHCache? Any other general best practices? Some clarifications - Could you partition the data? Yes we could but we're trying to avoid it. We need to run a lot of data mining algorithms and the design would evolve over time so we can't be sure what lines of partition should be there.

• Odd Android touch event problem

  - by user22241

  Overview When testing my game I came across a bizarre problem with my touch controls. Note this isn't related to multi-touch as I completely removed my ACTION_POINTER_UP and ACTION_POINTER_DOWN along with my ACTION_MOVE code. So I'm simply working with ACTION_UP and ACTION_DOWN now and still get the problem. The problem I have a left and right button on the left of the screen and a jump button on the right. Everything works as it should but if I touch a large area of my hand (the fleshy part at the base of the thumb for instance) onto the screen, then release it and then press one of my arrows, the sprite moves in that direction for a few seconds, and then ACTION_UP is mysteriously triggered. The sprite stops and then if I release my finger and re-apply it to an arrow, the same thing happens. This goes on and on and eventually (randomly??) stops and everything work OK again. Test device & OS Google Nexus 10 Tablet running Jellybean 4.2.2 Code //Action upon which to switch actionMask = event.getActionMasked(); //Pointer Index of the currently touching pointer pointerIndex = event.getActionIndex(); //Number of pointers (for multi-touch) pointerCount = event.getPointerCount(); //ID of the pointer currently being processed (Multitouch) pointerID = event.getPointerId(pointerIndex); switch (actionMask){ //Primary pointer down case MotionEvent.ACTION_DOWN: { //if pressing left button then set moving left if (isLeftPressed(event.getX(), event.getY())){ renderer.setSpriteLeft(); } //if pressing right button then set moving right else if (isRightPressed(event.getX(), event.getY())){ renderer.setSpriteRight(); } //if pressing jump button then set sprite jumping else if (isJumpPressed(event.getX(),event.getY())){ renderer.setSpriteState('j', true); } break; }//End of case //Primary pointer up case MotionEvent.ACTION_UP:{ //When finger leaves the screen, stop sprite's horizontal movement renderer.setSpriteStopped(); break; }

• problem adding bumpmap to textured gluSphere in JOGL

  - by ChocoMan

  I currently have one texture on a gluSphere that represents the Earth being displayed perfectly, but having trouble figuring out how to implement a bumpmap as well. The bumpmap resides in "res/planet/earth/earthbump1k.jpg".Here is the code I have for the regular texture: gl.glTranslatef(xPath, 0, yPath + zPos); gl.glColor3f(1.0f, 1.0f, 1.0f); // base color for earth earthGluSphere = glu.gluNewQuadric(); colorTexture.enable(); // enable texture colorTexture.bind(); // bind texture // draw sphere... glu.gluDeleteQuadric(earthGluSphere); colorTexture.disable(); // texturing public void loadPlanetTexture(GL2 gl) { InputStream colorMap = null; try { colorMap = new FileInputStream("res/planet/earth/earthmap1k.jpg"); TextureData data = TextureIO.newTextureData(colorMap, false, null); colorTexture = TextureIO.newTexture(data); colorTexture.getImageTexCoords(); colorTexture.setTexParameteri(GL2.GL_TEXTURE_MAG_FILTER, GL2.GL_LINEAR); colorTexture.setTexParameteri(GL2.GL_TEXTURE_MIN_FILTER, GL2.GL_NEAREST); colorMap.close(); } catch(IOException e) { e.printStackTrace(); System.exit(1); } // Set material properties gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_MAG_FILTER, GL2.GL_LINEAR); gl.glTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_MIN_FILTER, GL2.GL_NEAREST); colorTexture.setTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_WRAP_S); colorTexture.setTexParameteri(GL2.GL_TEXTURE_2D, GL2.GL_TEXTURE_WRAP_T); } How would I add the bumpmap as well to the same gluSphere?

• Server-side Architecture for Online Game

  - by Draiken

  Hi, basically I have a game client that has communicate with a server for almost every action it takes, the game is in Java (using LWJGL) and right now I will start making the server. The base of the game is normally one client communicating with the server alone, but I will require later on for several clients to work together for some functionalities. I've already read how authentication server should be sepparated and I intend on doing it. The problem is I am completely inexperienced in this kind of server-side programming, all I've ever programmed were JSF web applications. I imagine I'll do socket connections for pretty much every game communication since HTML is very slow, but I still don't really know where to start on my server. I would appreciate reading material or guidelines on where to start, what architecture should the game server have and maybe some suggestions on frameworks that could help me getting the client-server communication. I've looked into JNAG but I have no experience with this kind of thing, so I can't really tell if it is a solid and good messaging layer. Any help is appreciated... Thanks !

• Install gcc on Ubuntu 12.04 LTS

  - by Brian M. Hunt

  When I try to install gcc on Ubuntu 12.04 LTS Server with apt-get install gcc, I get the following error: The following packages have unmet dependencies: gcc : Depends: cpp (>= 4:4.6.1-2ubuntu5) but it is not going to be installed Depends: gcc-4.6 (>= 4.6.1-1) but it is not going to be installed Recommends: libc6-dev but it is not going to be installed or libc-dev When I delve deeper (i.e. try to apt-get install gcc-4.6), I get: gcc-4.6 : Depends: gcc-4.6-base (= 4.6.1-9ubuntu3) but 4.6.3-1ubuntu5 is to be installed Depends: cpp-4.6 (= 4.6.1-9ubuntu3) but it is not going to be installed Depends: libgomp1 (>= 4.6.1-9ubuntu3) but it is not going to be installed Depends: libquadmath0 (>= 4.6.1-9ubuntu3) but it is not going to be installed Recommends: libc6-dev (>= 2.13-0ubuntu6) but it is not going to be installed So when I try to install gcc-4.6=4.6.1-9ubuntu3 I get a list of 366 packages to remove (including e.g. apt). Which is craziness. This is an essentially vanilla installation of Ubuntu 12.04 LTS Server (i.e. I installed nginx, python-flup, python-yaml, rsync, python-pkg-resources, lsof, fontconfig, iptables, ufw, scons, and grc). It is very surprising to me that I cannot install gcc, so I am somewhat confused as to why attempting to install gcc fails. The only apparent fix would seem to be uninstalling 366 packages, many of which are central to the operation of Ubuntu. Something doesn't add up, and I would be very grateful for assistance. EDIT The above is with the latest packages of course, having used apt-get update; apt-get upgrade before attempting the above. Sorry, I should have mentioned that.

• How do you cope with change in open source frameworks that you use for your projects?

  - by Amy

  It may be a personal quirk of mine, but I like keeping code in living projects up to date - including the libraries/frameworks that they use. Part of it is that I believe a web app is more secure if it is fully patched and up to date. Part of it is just a touch of obsessive compulsiveness on my part. Over the past seven months, we have done a major rewrite of our software. We dropped the Xaraya framework, which was slow and essentially dead as a product, and converted to Cake PHP. (We chose Cake because it gave us the chance to do a very rapid rewrite of our software, and enough of a performance boost over Xaraya to make it worth our while.) We implemented unit testing with SimpleTest, and followed all the file and database naming conventions, etc. Cake is now being updated to 2.0. And, there doesn't seem to be a viable migration path for an upgrade. The naming conventions for files have radically changed, and they dropped SimpleTest in favor of PHPUnit. This is pretty much going to force us to stay on the 1.3 branch because, unless there is some sort of conversion tool, it's not going to be possible to update Cake and then gradually improve our legacy code to reap the benefits of the new Cake framework. So, as usual, we are going to end up with an old framework in our Subversion repository and just patch it ourselves as needed. And this is what gets me every time. So many open source products don't make it easy enough to keep projects based on them up to date. When the devs start playing with a new shiny toy, a few critical patches will be done to older branches, but most of their focus is going to be on the new code base. How do you deal with radical changes in the open source projects that you use? And, if you are developing an open source product, do you keep upgrade paths in mind when you develop new versions?
