• Moving from Silverlight 4 Beta to RC - Part 2

  In my previous post I talked about updating my development environment from Silverlight 4 Beta to Silverlight 4 RC (release candidate). After updating, I opened the solution for my Task-It project and found that several things were broken. I would've been surprised if it just worked as is! What disappointed me is that after spending a decent amount of time searching the web, I could not find information telling me what I needed to update/change...and wouldn't it be nice if there was a wizard to update it for you? What changed? I wish I had made notes along the line of each of the things I found, but here are a few that I can recall: In the Web project, the following dll's no longer exist: System.Web.DomainServices.dll System.Web.DomainServices.LinqToSql.dll (if you are using the Entity Framework I believe that one is System.Web.DomainServices.EntityFramework.dll) System.Web.Ria.dll In the Silverlight project: System.Windows.Ria.dll I'm not positive which new assemblies need to be referenced for your project, but I'm going to list the ones I think you need. One way to verify is to create a new Silverlight application with support for WCF RIA Services and see which dlls are included. In the Web project: System.Data.Entity.dll System.ServiceModel.DomainServices.EntityFramework.dll (I've moved from LinqToSql to EntityFramework, so I'm not sure which one the LinqToSql stuff comes from) System.ServiceModel.DomainServices.Hosting.dll System.ServiceModel.DomainServices.Server.dll In the Silverlight project: System.ServiceModel.DomainServices.Client.dll System.ServiceModel.DomainServices.Client.Web.dll System.ServiceModel.Web.Extensions.dll Where are these dll's? These all live in either the Silverlight or RIA Services subdirectories under:         C:\Program Files\Microsoft SDKs Of if you are on a 64-bit machine like me:         C:\Program Files (x86)\Microsoft SDKs Wrap up Good luck, and I hope this helps to get you back in business! If anyone finds anything that I've missed, please enter a comment and I'll update the post accordingly.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.

• Building a specific piece of Android platform?

• Why is Magento 1.4 including javascript files by filesystem path?

  - by Josh

  I am in the process of testing a Magento 1.3 site using Magento 1.4. I am seeing very weird and inconsistent behavior. Instead of including the URL of my javascript files, Magento is creating tags with the full filesystem path of the js files, as so: <script type="text/javascript" src="/home/my_username/public_html/js/prototype/prototype.js"></script> I believe this is related to the new "Themes JavaScript and CSS files combined to one file" function. In fact, when I log into the admin and click "Flush JavaScript/CSS Cache", then the first page load is successful, and I see a single JS include similar to: <script type="text/javascript" src="/media/js/5b8cfac152fcb2a5f93ef9571d338c54.js"></script> But subsequent age loads load every single JS file, with the full path names. Which obviously isn't going to work. Anyone have any ideas on what could be wrong or how to fix this issue?

• Unit Tests as a learning tool - a good idea?

  - by Ekkehard.Horner

  I'm interested in ways and means for learning (a) programming language(s) efficiently. I believe that using Unit Test concepts and infrastructure early in that process is a good thing, even better than starting with "Hello world". Why: To write a decent program even for a toy/restricted problem in a new language, you'll have to master many heterogenous concepts (control flow & variables & IO ...), you are tempted to glance over details just to get your program 'to work'. Putting (your understanding of) the facts about the new language in assertions with good descriptions (=success messages) enforces thinking thru/clearness/precision. Grouping topics and adding assertions to such groups is much easier than incorporation features from the 2. chapter of your "Learning X" book to your chapter 1 program. Why not: 'Real' Unit Tests are meant to output "1234 tests ok; 1 failure: saveWorld() chokes on negative input"; 'didactic' Unit Tests should output relevant facts about the new language like perl6 10-string.t # ### p5chop ... ok 13 - p5chop( "cbä" ) returns "ä" ok 14 - after that, victim is changed to "cb" # ### (p6) chop ... ok 27 - (p6) chop( "cbä" ) returns chopped copy: "cb" ok 18 - after that, victim is unchanged: "cbä" # ### chomp ... So (mis?)using Unit Tests may be counterproductive - practicing actions while learning you wouldn't use professionally. How: Writing 'didactic' Unit Tests in languages with lightweight testing systems (Perl 5/6) is easy; (mis?)using more elaborate systems (JUnit, CppUnit) may be not worth the effort or not suitable for a person just starting with a new language. So Is using Unit Tests as a learning tool a bad idea? Can the Unit Test tool(s) of your favourite language(s) used didactically? Should implementation details (eventually) be discussed here or over at stackoverflow.com?

• Dynamically pulling images from XML for iPhone App

  - by Simon Hume

  I've got my iPhone app pulling down live data content via XML nicely, and I've formatted the UITableView cells to display the content without too many headaches. However, at the moment, for each cell I'm just showing a default graphic for now, but I want this to be pulled down from my server too. The code snippet that grabs the image (which is actually in my project) is: cell.imageView.image = [UIImage imageNamed:@"TBC.png"]; But that will need to be the dynamic image. In my XML, am I better just returning 'mypic.png' and let the SDK determine the full path, like http://myapp.com/mypic.png or storing the full URL to the image in the XML?

• Is paper indispensable in a programmer's everyday work?

  - by rwong

  As a programmer who work in a company whose vision is to make paperless office possible, is there any way I can work effectively while using less paper? I can list at least several kinds of papers I use quite often: Paper notebook, on which I do most of the pre-coding design work and ideas Books Temporary printouts of source code, though not so often (in color, with a 6 point font at 600 DPI) Sticky note, to remind myself of things that should be taken care of within a few days On the other hand, I also use a wiki and an office text editor. Once a while I would use a diagramming software to make a few flowcharts. Deeper questions: Is there a relationship between paper use and productivity? How can programmers help save the trees? Is paperless software development fundamentally different from paperless office? Related questions: Do you ever write code with pen and paper, and should we do it more often? What physical tools do you find useful to work as a programmer? What things are essential on a programmer's desk? Stuff every programmer needs while working Additional info, if it helps: Everyone has dual monitors. We have decent project management and issue tracking software (both web-based). Please be constructive. In particular, please give your answer to your peer programmers who wish to be flexible and are willing to change working style in order to become more productive as well as meeting certain their own personal values. Edited: I removed the company's view because it appears to be too flamebait. If you need to see my original words, go to the edit history. Deleted: Doxygen and whiteboard. Reason: disregarding my personal experience with these great tools, we never had to print out anything as a consequence of using/not using them. To see my original words, go to the edit history.

• #altnetseattle &ndash; MEF, What is it?

  - by GeekAgilistMercenary

  I dived into the MEF session with Glenn Block, Sourabh Mathur, Brian Henderson, and others.  Glenn covered the basic architectural ideas of MEF and then dived into a few examples. Is a framework around decoupling components. Built around the idea of discoverable type systems. Traditional extensibility mechanisms have a host and the respective extensions, commonly linking these two aspects with a form of registration. MEF removes the need for the registration part of the architecture and uses a contract. At some point with MEF you get down to parts, which removes even the complexity of a host or extensions, but a truly evolvable architecture based on natural growth of parts. Also referred to as the framework that removes the "new" keyword. The idea is that parts pull together other parts that they need.  Between each part is a contract. Each part has imports or exports for the parts it needs or the things it offers. If one checks out the MEF Codeplex Site you will find a host of additional information.  The framework download also has some decent examples that help one get kick started.

• I cannot solve the "Install these packages without verification" problem

  - by Yonatan Orlev

  I Googled and Googled and I just cannot find a solution to this problem: sudo apt-get install <whatever> Gives me: WARNING: The following packages cannot be authenticated! and Install these packages without verification [y/N]? I cannot find a decent solution. The closest I got was to run: sudo apt-get install debian-keyring debian-archive-keyring But then, even thought, and against my good judgment I agreed to install the package without confirmation, I get: (I replaced http with XXXX because of forum limitations). Install these packages without verification [y/N]? y Err XXXX://il.archive.ubuntu.com gutsy/universe debian-archive-keyring 2007.02.19-0.1 404 Not Found Err XXXX://il.archive.ubuntu.com gutsy/universe debian-keyring 2005.05.28 404 Not Found Failed to fetch XXXX://il.archive.ubuntu.com/ubuntu/pool/universe/d/debian-archive-keyring/debian-archive-keyring_2007.02.19-0.1_all.deb 404 Not Found Failed to fetch XXXX://il.archive.ubuntu.com/ubuntu/pool/universe/d/debian-keyring/debian-keyring_2005.05.28_all.deb 404 Not Found E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? Trying to run apt-get update also does not help: I get tons of "404 Not Found" errors. Can someone please direct me to a good solution to this problem?

  I have a full page flash animation. When this page is open at Firefox and I want to minimize or re-size Firefox screen, minimize button starts to blink and Firefox does not take any action till this tab is closed. There is not too much code in the flash file. What can cause this? Also this could not be related with full page. I saw other flash files doing same thing. As I remember same problem at Daily Motion. When trying to switch tab nothing happens till I stop video or close the tab.

• css border problem

  For some reason I have a very ugly orange part of a border around a image. Can anyone see why this is? This is the HTML <div class="preview"> <a href="images/foto/full/280899624_6_5_j6.jpeg" title="Sportschool Raymond Snel" rel="lightbox"><img src="images/foto/full/280899624_6_5_j6.jpeg" alt="text" /></a> </div> This is the css .preview { width: 85px; height: 85px; overflow: hidden; border: 3px solid #2e2a26; } The color code = FF6a00 but appears only one time in the css file. a { color: #ff6a00; text-decoration: none; border: 0px; } As you can see I already gave it a 0px, but for some reason the border is still there.

• Project Codenames - Yea or Nay?

  - by rmx

  Where I work, most of our projects have (or at least attempt) descriptive, useful names. However we have a few with names that make no sense: I found that an assembly named WiFi which actually has nothing whatsoever to do with wi-fi, but is a codename. When I asked why, I was told that it's to protect company secrets incase some intern has few too many at the pub on Friday and starts chatting about the brand new 'WiFi' project he's been working on. Its clear that some people find enjoyment in finding silly / amusing codenames for their projects (like in this question). My question is: is it really a good idea to use codenames for your projects or are you better off spending the time to decide upon a descriptive name? My opinion is that in the long-run its better to give your projects relevant names. My reasoning is that if you can't think of a decent name, perhaps you don't really know the requirements well enough. I think there are better ways to 'protect company secrets' and I find it quite confusing when the name does not correlate at all with the content. It's just common sense, surely?! So do you use codenames and what the your reasons for or against this seemingly common, yet annoying (to me at least) practice?

• How to move a google doc into a folder using Zend Gdata

  - by Andre

  Hi Guys I am really struggling with moving a document from my root folder to another folder using zend gdata here is how i am trying to do it, but its not working. $service = Zend_Gdata_Docs::AUTH_SERVICE_NAME; $client = Zend_Gdata_ClientLogin::getHttpClient($gUser, $gPass, $service); $link = "https://docs.google.com/feeds/documents/private/full/spreadsheet:0AUFNVEpLOVg2U0E"; // Not real id for privacy purposes $docs = new Zend_GData_Docs($client); // Attach a category object of folder to this entry // I have tried many variations of this including attaching label categories $cat = new Zend_Gdata_App_Extension_Category('My Folder Name','http://schemas.google.com/docs/2007#folder'); $entry = $docs->getDocumentListEntry($link); $entry->setCategory(array($cat)); $return = $docs->updateEntry($entry,$entry->getEditLink()->href); When I run this I get No errors, but nothing seems to change, and the return data does not contain the new category. EDIT: Ok I realised that its not the category but the link that decides which "collection" (folder) a resource belongs too. https://developers.google.com/google-apps/documents-list/#managing_collections_and_their_contents says that each resource has as et of parent links, so I tried changing my code to do set link instead of set category, but this did not work. $folder = "https://docs.google.com/feeds/documents/private/full/folder%3A0wSFA2WHc"; $rel = "http://schemas.google.com/docs/2007#parent"; $linkObj = new Zend_Gdata_App_Extension_Link($folder,$rel,'application/atom+xml', NULL,'Folder Name'); $links = $entry->getLink(); array_push($links,$linkObj); $entry->setLink($links); $return = $docs->updateEntry($entry,$entry->getEditLink()->href); EDIT: SOLVED [nearly] OK Here is how to move/copy, sort of, from one folder to another: simpler than initially thought, but problem is it creates a reference and NOT a move! It now in both places at the same time.... // Folder you wnat to move too $folder = "https://docs.google.com/feeds/folders/private/full/folder%asdsad"; $data = $docs->insertDocument($entry, $folder); // Entry is the entry you want moved using insert automatically assigns link & category for you...

• Suitable SDK to develop quick game?

  - by gRnt

  I'm currently undertaking a personal project at home that I need to turn around inside the next few months (which working full time and still learning programming makes it a tad difficult). I'm looking for suggestions on SDK's or tools (preferably free or that come with games, similar to steam tools) that I can use to develop a "game". I'm OK with coding but have no 3D development skills at all. I've very little experience with mod tools or SDK's at all but I'm hoping someone can point me in the direction of one that does the following: A decent library of prefab 3D models to build scenes. Ability to add scripting to the scene I've used Unity before and would prefer to continue to do so however I really have the worst 3D skills imaginable and can't waste time learning them. I'd be looking for pre-fab items that are both industrial and possibly more lush environments (trees etc). If it makes any difference (due to licencing and what-not) I WILL NOT be selling this game or marketing it in any way and I am a University Student if any places do educations licences. Another alternative would be to source free 3d models elsewhere but again while I'm still learning I have no idea where to look if someone could point me in the right direction I'll do the rest of the digging. Thanks

• Animating DOM elements vs refreshing a single Canvas

  - by mgibsonbr

  A few years ago, when the HTML Canvas element was still kinda fresh, I wrote a small game in a rather "unusual" way: each game element had its own canvas, and frequently animated elements even had multiple canvases, one for each animation sprite. This way, the translation would be done by manipulating the DOM position of the canvases, while the sprite animation would consist of altering the visibility of the already drawn canvases. (z-indexes, of course, were the tricky part) It worked like a charm: even in IE6 with excanvas it showed a decent performance, and everything was rather consistent between browsers, including some smartphones. Now I'm thinking in writing a larger game engine in the same fashion, so I'm wondering whether it would be a good idea to do so in the current context (with all the advances in browsers and so on). I know I'm trading memory for time, so this needs to be customizable (even at runtime) for each machine the game will be running. But I believe using separate canvases would also help to avoid the game "freezing" on CPU spikes, since the translation would still happen even if the redraws lag for a while. Besides, the browsers' rendering engines are already optimized in may ways, so I'm guessing this scheme would also reduce the load on the CPU (in contrast to doing everything in JavaScript - specially the less optimized ones). It looks good in my head, but I'd like to hear the opinion of more experienced people before proceeding further. Is there any known drawback of doing this? I'm particulartly unexperienced in dealing with the GPU, so I wonder whether this "trick" would nullify any benefit of using a single, big canvas. Or maybe on modern devices it's overkill (though I'm skeptic about the claims that canvas+js - especially WebGL - will ever be a good alternative to native code). Any thoughts?

• How does one escape the GPL?

  - by tehtros

  DISCLAIMER I don't pretend to know anything about licensing. In fact, everything I say below may be completely false! Backstory: Recently, I've been looking for a decent game engine, and I think I've found one that I really like, Cafu Engine. However, they have a dual licensing plan, where everything you make with the engine is forced under GPL, unless you pay for a commercial license. I'm not saying that it's a bad engine, they even say that they are very relaxed about the licensing fees. However, the fact that it even involves the GPL scares me. So my question is basicly, how does one escape the GPL. Here's an example: The id Tech engine, also known as the Quake engine, or the Doom engine, was the base for the popular Source engine. However, the id Tech engine has been released under the GPL, and the Source engine is proprietary. Did Valve get a different license? Or did they do something to escape the GPL? Is there a way to escape the GPL? Or, if you use GPL'd source code as a base for another project, are you forced to use the GPL, and make your source code available to the world. Could some random person take the id Tech engine, modify it past the point of recognition, then use it as a proprietary engine for commercial products? Or are they required to make it open source. One last thing, I generally have no problem what-so-ever with open source. However I feel that open source has it's place, but that is not in the bushiness world.

• How to force VS 2010 to skip "builds" of projects which haven't changed?

  - by Ladislav Mrnka

  Our product's solution has more than 100+ projects (500+ksloc of production code). Most of them are C# projects but we also have few using C++/CLI to bridge communication with native code. Rebuilding the whole solution takes several minutes. That's fine. If I want to rebuilt the solution I expect that it will really take some time. What is not fine is time needed to build solution after full rebuild. Imagine I used full rebuild and know without doing any changes to to the solution I press Build (F6 or Ctrl+Shift+B). Why it takes 35s if there was no change? In output I see that it started "building" of each project - it doesn't perform real build but it does something which consumes significant amount of time. That 35s delay is pain in the ass. Yes I can improve the time by not using build solution but only build project (Shift+F6). If I run build project on particular test project I'm currently working on it will take "only" 8+s. It requires me to run project build on correct project (the test project to ensure dependent tested code is build as well). At least ReSharper test runner correctly recognizes that only this single project must be build and rerunning test usually contains only 8+s compilation. My current coding Kata is: don't touch Ctrl+Shift+B. The test project build will take 8s even if I don't do any changes. The reason why it takes 8s is because it also "builds" dependencies = in my case it "builds" more than 20 projects but I made changes only to unit test or single dependency! I don't want it to touch other projects. Is there a way to simply tell VS to build only projects where some changes were done and projects which are dependent on changed ones (preferably this part as another build option)? I worry you will tell me that it is exactly what VS is doing but in MS way ... I want to improve my TDD experience and reduce the time of compilation (in TDD the compilation can happen twice per minute). To make this even more frustrated I'm working in a team where most of developers used to work on Java projects prior to joining this one. So you can imagine how they are pissed off when they must use VS in contrast to full incremental compilation in Java. I don't require incremental compilation of classes. I expect working incremental compilation of solutions. Especially in product like VS 2010 Ultimate which costs several thousands dollars. I really don't want to get answers like: Make a separate solution Unload projects you don't need etc. I can read those answers here. Those are not acceptable solutions. We're not paying for VS to do such compromises.

• Using django-haystack, how do I perform a search with only partial terms?

  - by Sri Raghavan

  I've got a Haystack/xapian search index for django.contrib.auth.models.User. The template is simply {{object.get_full_name}} as I intend for a user to type in a name and be able to search for it. My issue is this: if I search, say, Sri (my full first name) I come up with a result for the user object pertaining to my name. However, if I search Sri Ragh - that is, my full name, and part of my last name, I get no results. How can I set Haystack up so that I can get the appropriate results for partial queries? (I essentially want it to search *Sri Ragh*, but I don't know if wildcards would actually do the trick, or how to implement them). This is my search query: results = SearchQuerySet().filter(content='Sri Ragh')

• Static "LoD" hack opinions

  - by David Lively

  I've been playing with implementing dynamic level of detail for rendering a very large mesh in XNA. It occurred to me that (duh) the whole point of this is to generate small triangles close to the camera, and larger ones far away. Given that, rather than constantly modifying or swapping index buffers based on a feature's rendered size or distance from the camera, it would be a lot easier (and potentially quite a bit faster), to render a single "fan" or flat wedge/frustum-shaped planar mesh that is tessellated into small triangles close to the near or small end of the frustum and larger ones at the far end, sort of like this (overhead view) (Pardon the gap in the middle - I drew one side and mirrored it) The triangle sizes are chosen so that all are approximately the same size when projected. Then, that mesh would be transformed to track the camera so that the Z axis (center vertical in this image) is always aligned with the view direction projected into the XZ plane. The vertex shader would then read terrain heights from a height texture and adjust the Y coordinate of the mesh to match a height field that defines the terrain. This eliminates the need for culling (since the mesh is generated to match the viewport dimensions) and the need to modify the index and/or vertex buffers when drawing the terrain. Obviously this doesn't address terrain with overhangs, etc, but that could be handled to a certain extent by including a second mesh that defines a sort of "ceiling" via a different texture. The other LoD schemes I've seen aren't particularly difficult to implement and, in some cases, are a lot more flexible, but this seemed like a decent quick-and-dirty way to handle height map-based terrain without getting into geometry manipulation. Has anyone tried this? Opinions?

• GitHub: Are there external tools for managing issues list vs. project backlog

  - by DXM

  Recently I posted one of my the projects1 on GitHub and as I was exploring capabilities of the site, I noticed they have a rather decent issue tracking section. I want to use that section as a) other people can report bugs if they'd like and b) other people can see which bugs I'm aware of. However, as others have noted, issues list cannot be prioritized in order to create a project backlog. For now my backlog has been a text file, but I'd like to be able to have it integrated so the same information isn't maintained in different places. Having a fully ordered list, which is something we also practice at work, has been very useful as I can open one file, start with line 1 and fire off 2 or 3 items in one sitting without having to go back to a full issues/stories bucket. GitHub doesn't offer this. What GitHub does offer is a very nice and clean API so issues can easily be exported into anything else. I've searched to see if there are other websites (like Trello) that integrate with GitHub issues, but did not find anything. Does anyone know of such a product, service or offline tool? Those that use GitHub, what is your experience in managing backlog? I kinda hate the idea of manually managing two disconnected lists like some people seem to be doing with Wiki project pages. 1 - are shameless plugs allowed no this site? Searched but didn't find a definite answer. If it's bad practice, STOP and don't read further As a developer I got sick and tired of navigating to same set of folders 30 times a day, so I wrote a little, auto-collapsible utility that gets stuck to the desktop and allows easy access to the folders you constantly use.
