  • Performance of pixel shaders vs. SpriteBatch: XNA

    - by ashes999
    Precondition: I read this question/answer about using shaders, or spritebatch, to render and mark a sprite. I need to do something like that. I also have a 2D lighting PoC which I need to write. The way it will work will basically be something like: Draw all the sprites Draw lighting gradients to create a lighting texture Multiply/add the lighting texture to achieve different effects (I use multiple passes of add/multiply the lighting texture to achieve different effects.) My question is really about a generalization: can I say with certainty that pixel shaders are always faster than adding/multiplying textures to the SpriteBatch? Or that adding/multiplying is always faster? Or if it's not generalizable, how do I decide which approach to take, given that I can probably code either of them? (If it matters, I'm using MonoGame 3.0 beta for Windows games)

  • TFS work items tips

    - by Michael Freidgeim
    We started to use TFS to track requests using Work items. 1. Telerik's  TFS Work Item Manager (beta version for TFS 2010 is available) that could be interesting to use instead of standard VS2010, especially for someone who doesn’t want to have VS installed on their machine.(thanks to dimarzionist who pointed to the tool).See also TFS Project Dashboa 2.Visual Studio TFS work item attachments Tab I've found that Outlook emails can be dropped to TFS work item attachments. Just open TFS work item attachment tab and drag and drop Outlook email to it. Also you can copy any selected text and paste it to TFS work item attachments tab. The text will be saved as an attachment file.

  • Temporarily share/deploy a python (flask) application

    - by Jeff
    Goal Temporarily (1 month?) deploy/share a python (flask) web app without expensive/complex hosting. More info I've developed a basic mobile web app for the non-profit I work for. It's written in python and uses flask as its framework. I'd like to share this with other employees and beta testers (<25 people). Ideally, I could get some sort of simple hosting space/service and push regular updates to it while we test and iterate on this app. Think something along the lines of dropbox, which of course would not work for this purpose. We do have a website, and hosting services for it, but I'm concerned about using this resource as our website is mission critical and this app is very much pre-alpha at this point. Options I've researched / considered Self host from local machine/network (slow, unreliable) Purchase hosting space (with limited non-profit resources, I'm concerned this is overkill) Using our current web server / hosting (not appropriate for testing) Thanks very much for your time!

A real focus has been put on making the request process more business user friendly, and a lot of new customization capability has been added for the IT administrators.

    I upgraded to the 12.04 beta yesterday. Now, when I try to start Eclipse, I get the splash screen and then this error message: An error has occurred. See the log file /home/gabriel/.eclipse/org.eclipse.platform_3.7.0_155965261/configuration/1335382319394.log .

  • Web standards or risk avoidance?

    - by Junior Dev
    My company is building an App Engine application. The app encounters a bug (possibly due to an issue with App Engine itself, as per our research) on IE9, but it cannot be reliably reproduced and is experienced by a small percentage of users. The workaround is to force IE9 to use IE8 mode. As a lazy front end developer (who doesn't like CSS hacks, shims and polyfills) I think it's OK to at least try going back to IE9 mode and see what happens, while we're still in private beta. The senior engineer (being more pragmatic) would rather that we continue forcing IE9 users to use the older IE8 mode. Who is right?

  • How do early version numbers work for new products?

    - by Lord Torgamus
    I'm currently writing a small desktop application for a friend, but I'm doing it primarily as a learning experience for myself. In the spirit of getting educated and doing things The Right Way, I want to have version numbers for this app. My research brought up these related results What "version naming convention" do you use? How do you version your files (Version Numbers) Forked a project, where do my version numbers start? but none of them address numbering of alphas, betas, release candidates, &c. What are the conventions for version numbers below 1.0? I know they can go on for some time; for example, PuTTY has been around for at least a decade and is still only at version beta 0.60.

  • Open XML SDK 2 Released

    - by Tim Murphy
    Note: Cross posted from Coding The Document. Permalink This post is a little late since the SDK was released about a week ago.  At PSC we have been using the Open XML SDK 2 since its earliest beta.  It is a very powerful tool for generating documents without using the Office DLLs.  It is also the main technology that I have been working with for the last six months.  I would suggest giving it a try.  Stay tuned here.  In the near future I will be presenting at different locations on this and other document generation technologies.

  • How can I install Ubuntu Saucy Server with BTRFS?

    - by Walter Souto
    So, a week ago I installed the latest beta version of Ubuntu Saucy Server in a MacMini using BTRFS as only partition to mount "/" on it (I know it's not recommended to do this, but it's not the point here) with no problems et al. Everything went just "naturally"... Now with the released image of 13.10 server, I just can't get any BTRFS partition done from installer. I'm getting a "Can't create filesystem" error whenever I try to create any BTRFS partition, like the 13.10 server final installer can't handle format BTRFS partitions... Am I doing something wrong? Or it's a bug in the installer? Is there anything that I can do to workaround this and get my BTRFS partition set on installation, or I'll need to work this after the installation. I can just leave some space left and create a btrfs partition later on, with Saucy already installed and proceed to use to LXC (which is my solo purpose to have btrfs), but anyway, why installer can't do btrfs anymore?

  • Fan running constantly on a Dell D420 laptop

    - by Halik
    I'm running latest Ubuntu 12.04 beta on a Dell D420 laptop. The fan is spinning almost constantly - even after turning the PC off, letting it cool down, and then turning it back on, the fan will turn on after some idle time. Not to mention any CPU work. The CPU temps are normal, in range of 50-55 idle, and up to 70 with some load. It wouldn't be an issue, but the same PC running Fedora, or Arch Linux, had a much more modest fan profile - the temps were managed while you seldom heard the fan. To counter the problem, I currently use i8k tools, set manual temperature thresholds which seemed to have worked, but the i8kmon has a tendency to cycle the fan between lower and higher state within aboutin a second intervals - which is extremely annoying. As far as I can tell I did not run any special software (beside laptop-mode-tools), or any additional kernel modules when running Arch Linux and I can't tell about Fedora.

  • Apps missing in Software Centre

    I'm using Elementary OS Luna beta 1, based on Ubuntu 12.04 Precise. I used to used Quantal, as I remember there were roughly 68000 apps. Massive commercial apps, and the banner on top shows new hot apps all the time. Now I switch to Elementary because Compiz sucks with Nvidia. However, Software Centre now only has 41000 apps. No commercial apps, no 3rd party apps. I'm pretty sure I have all the sources enabled: My sources.list: http://paste.ubuntu.com/1396213/
