• dual-boot (win-xp/ubu12.04) graphics card for ubu-desktop/win-xp-games

  - by iole1

  for work I need to get a a new and cheap graphics card for a dual boot machine: windows xp/ubuntu 12.04 LTS. The only requirements I have are: it should work 'flawlessly' in ubuntu (proprietary drivers are ok) it should handle Guild Wars 2 & League of Legends in windows xp (this is really the top priority as we need to be able to play at work :) - yes I have a cool job) I know nothing about graphics cards (and it seems to be a jungle out there). From other questions here and some webstigation I think I'd like to go for a Nvidia card, I've been trying to figure out what models fit the system req's but it seems they use different kind of model numbers so I don't get any wiser. tl;dr: will http://www.geforce.co.uk/hardware/desktop-gpus/geforce-gt-620-oem/specifications run Guild Wars 2 http://gamesystemrequirements.com/games.php?id=938 Or what is the worst card from nVidia that will run GW2 smoothly and work well in Ubuntu 12.04 Thanks!

• Nimbus Tweaking Help Needed

  - by Geertjan

  I was reading this new article on Synthetica and NetBeans RCP this morning, when I remembered this screenshot from Henry Arousell from Sweden: Here, Nimbus is heavily being used, highlighting 6 areas where Henry would really benefit from any help regarding how the foreground properties should be set: The color of the main menu (and its subsequent unfolded menu options) The TopComponent tab colors (as you can see from the screenshot, they've managed to change the foreground colors of the ones in the editor mode by setting the Nimbus property "TextText"). They cannot manipulate TopComponents in other modes, though. Table header foreground colors The foreground color of any provided composite component, like a JFileChooser or the ICEPdf viewer or any other panel with label components. The progress bar message color. The status bar message color, A Nimbus expert is needed to help here, though it seems to me that some of the solutions have already been identified, or are similar, in the article pointed out above.

• Would using AJAX only "Add to Cart" buttons be wise?

  - by Alex Erwin

  I want to AJAX enable all of my Add To Cart buttons because search engine bots are indexing these and not paying attention to my robots file or site map. I just don't want to loose potential customers. I have seen a number of top sites using heavily JavaScript support content, including Amazon, is it OK to follow the trend? The rest of my site progressively degrades, but I would really like to implement this because of the benefits to the customer (instant satisfaction), my infrastructure (constant page rebuilds), and allowing me to use SEO tools to optimize without the tool picking up thousands of "Add to Cart" widgets in my catalog. Thanks

• Writing a job requirement for a web application developer

  - by Raul Agrait

  I'm currently writing a job requirement for a software engineer position for my company, in which we are looking for a developer to work on client-side web application work. How should I title the job title / position? I don't necessarily want to call it a "Web Developer", for fear that it might attract more designer-y types. On the other hand, "Software Engineer" doesn't really give the indication that the work, while application based, will be web-based. Is "Web Application Software Engineer" a valid position title? Also, I'm somewhat torn on what the required skills set should be. I don't necessarily think that the ideal candidate should have x years of experience in say, JavaScript or ActionScript, but rather am just looking for someone who has experience in developing client-side applications, and is willing to learn and develop web applications. My current attempt at this, is that I have a section in which I state: Experience in the following frameworks and technologies are a plus, but not necessarily required for the position:

• What is the most efficient way to blur in a shader?

  - by concernedcitizen

  I'm currently working on screen space reflections. I have perfectly reflective mirror-like surfaces working, and I now need to use a blur to make the reflection on surfaces with a low specular gloss value look more diffuse. I'm having difficulty deciding how to apply the blur, though. My first idea was to just sample a lower mip level of the screen rendertarget. However, the rendertarget uses SurfaceFormat.HalfVector4 (for HDR effects), which means XNA won't allow linear filtering. Point filtering looks horrible and really doesn't give the visual cue that I want. I've thought about using some kind of Box/Gaussian blur, but this would not be ideal. I've already thrashed the texture cache in the raymarching phase before the blur even occurs (a worst case reflection could be 32 samples per pixel), and the blur kernel to make the reflections look sufficiently diffuse would be fairly large. Does anyone have any suggestions? I know it's doable, as Photon Workshop achieved the effect in Unity.

• How to produce assets effectively on large Flash game projects?

  - by Antoine Lassauzay

  I have been working on Flash games professionally for two years now and somehow, having our artists producing assets the right way is one of our biggest challenge. More precisely, it is very hard to have them following any kind of structure and/or standards, nor taking into consideration performance. I would say also the most of our issues concerns UI and related animations. Our current workflow is (on a Facebook hidden object game) : Artists produce PSD and animate prototypes in Flash Artists re-organize their FLA files to be a bit more "programmer friendly" Programmers retouches assets until they have the right structure and export classes inside a SWC, from Flash Programmers try to improve performances, sometimes degrading the quality of game graphics Our main idea is to hire somebody dedicated to prepare assets for programmers but I am really looking forward to improving the pipeline. I was wondering if you guys have tips of any kind to improve this workflow, whether it be team organization, training, tools or tips with Flash. Any explanation on your asset pipeline is well appreciated too.

• Mobile game production workflow using Html5 and visual studio

  - by Mihalis Bagos

  I want to know of any framework, that lets you build/test applications inside Visual Studio using Html5/JS. We need to be able to have an emulator (like the one on android sdk) for as many devices as possible, and we need to be able to run the application with as few steps as possible (using the "RUN" command in visual studio is no1 choice). Also, this extends to build and deployment to app stores. Is there a way to circumvent the cloud services and build locally? I am at a loss of the plethora of tools and technologies available for game design using Html5. However, I really don't like the way implementations try to get you to rely on their cloud services, so services like appmobi are at the bottom of the favored list.

• Should I migrate to MVC3?

  - by eestein

  Hi everyone. I have a MVC2 project, my question is: should I migrate to MVC3? Why? I'd like the opinion of some who already migrated, or at least used MVC3 and MVC2. Already read http://weblogs.asp.net/scottgu/archive/2011/01/13/announcing-release-of-asp-net-mvc-3-iis-express-sql-ce-4-web-farm-framework-orchard-webmatrix.aspx and I already know about the described tool for migrating: http://blogs.msdn.com/b/marcinon/archive/2011/01/13/mvc-3-project-upgrade-tool.aspx What I'd really appreciate is your valuable insight. Best regards.

• is it a bad practice to call a View from another View in MVC?

  - by marcos.borunda

  I have some plain Views, they don't have any logic behind them (there is no action or controller behind them), their only propouse is to alert the user about something like "We have sent you an email to confirm your account", "You have no access to this resource", etc... These views are really simple, and calling them through a Controller/Action seems to be too much overhead, but somehow I feel like it is not quite correct. What do you think? How do you handle this kind of situations?? I guess this question will apply to any MVC Framework, but in my case I'm using the ASP.NET MVC 3 framework.

• Why use flash to as content headings? Why not?

  - by Itai

  A large number of sites lately which use Flash to replace what would be simple HTML headings (h1, h2, h3). Some of them do it consistently for every header. Why would you do this? What are the pros and cons of this? This seems strange to me and really inefficient, particularly since a page can have dozens of headers. I notice this because I use Flash Block (which temporarily disables Flash), so not everyone may have seen it. Just today I landed here with 4 flash headers. I've seen dozens of such use of Flash this week alone, and I am wondering if this has some benefits.

• j2ee implementing security and using a framwork pros and cons

  - by Ismail Marmoush

  I'm a newbie to j2ee security, and i'm not j2ee expert either, though i'm really willing to put some effort and learn I've an application that i'm about to develop on Google App Engine (GAE) --with no time constraints. As you know GAE handles a lot of web container security issues for you, also I will be using openID for authentication exclusively (sessions will be handled by provider). GAE supports SSL which will help with confidentiality and integrity maybe. Authorization can be done through filters. I know reinventing the wheel is a mess, but I was looking forward to learn something about security and implement that in my new app. so what the pros and cons of using a framework like shiro, spring security, jguard etc or filling the rest of gaps on my own ?

• Technology/Programming mailing lists How do you manage?

  - by AdityaGameProgrammer

  Email Alerts, Blog /Forum updates, discussion subscriptions general programming/technology update emails that we often subscribe to.Do you actually read them ? or go direct to the source when you find time. Often we might the mail of programmers filled with loads of unread subscription mail from technology they previously were following or worked on or things they wish to follow .Some or a majority of these mail just keep on piling up . I personally have few updates that i wish i read but constantly avoid and keep of for latter and finally delete them in effort keep the in box clean. Few questions come to mind regarding this Do you keep such mail in separate accounts? Do you read all the mail you have subscribed to? Do you ever unsubscribe to any such email if you aren't reading them? How much do you really value these email. Lastly do you keep your in box clean ? wish to deal with this in a better way.

• No VB6 to VS2010 direct upgrade path

  - by Chris Williams

  From the "is this really news?" department... From looking at the currently available versions of 2010, there is no direct upgrade path from VB6 to VS2010. Anyone still using VB6 and wishing to upgrade to VS2010 has two options:  Use the upgrade tool from an earlier version of VS (like 2005 or 2008) and then run the upgrade in VS2010 to get the rest of the way... or rewrite your code. I'll leave it as an exercise to the reader which is the better option. I'd like to take a moment to point out the obvious: A) If you're still using VB6 at this point, you probably don't care about VS2010 compatibility. B) Running your code through 2 upgrade wizards isn't going to result in anything resembling best practices. C) Bemoaning the lack of support in 2010 for a 12 year old version of an extinct programming language helps nobody. This public service announcement is brought to you by the letter C. Thank you.

• Why does the word "Pythonic" exist?

  - by Billy ONeal

  Honestly, I hate the word "Pythonic" -- it's used as a simple synonym of "good" in many circles, and I think that's pretentious. Those who use it are silently saying that good code cannot be written in a language other than Python. Not saying Python is a bad language, but it's certainly not the "end all be all language to solve ALL of everyone's problems forever!" (Because that language does not exist). What it seems like people who use this word really mean is "idiomatic" rather than "Pythonic" -- and of course the word "idiomatic" already exists. Therefore I wonder: Why does the word "Pythonic" exist?

• Getting many files from a SharePoint Document Library the easy way

  - by Stacy Vicknair

  As an individual who does not use Internet Explorer as their primary browser, there is a great feature that you may never notice that allows you to easily copy files to and from a document library: the Open in Windows Explorer link. In browsers such as Chrome or Firefox this link may not appear. I know this isn’t a major groundbreaking feature, but it’s really easy to overlook and it’s worth knowing about, especially when you need to create a local copy of a full document library. In this quick blog we’ll go over how to access this feature in both SharePoint 2007 and 2010. First, make sure you are in Internet Explorer. These options may not show in other browsers. In SharePoint 2007, browse to the document library you would like to access then select Actions > Open with Windows Explorer. In SharePoint 2010, browse to the document library you would like to access then select Library Tools > Library > Open with Explorer from the ribbon.
