How to shade a texture two different colors?

- by Venesectrix

To give an example of what I'm asking about, I'll use Saints Row 3 since I've been playing that lately. In that game you can customize your looks and your car's appearance a lot. Your coat can have a primary color and a trim color. Your car can have a primary color and a stripe color, etc. Is there just a single coat texture that is being shaded two different colors somehow or are they overlaying a transparent second texture for the trim/stripes that gets shaded differently? If it's just one texture I'd like to know how it's done. If it's two different textures it seems like it's a waste of space. The second texture would be the same size as the first one but mostly transparent if you just wanted to lay it on top of the first one. Or are they just carefully positioning a second, smaller texture so that it aligns properly with the first one?

Only close button shows up in Google Chrome in GNOME Shell

- by TreefrogInc

After I installed the GNOME shell in Ubuntu, I decided that I didn't like having the "Close/Minimize/Maximize" buttons on the right, so I switched them over to the left using gconftool-2 --set "/apps/metacity/general/button_layout" --type string "close, minimize, maximize:" After resetting the shell, however, I found that with the GTK+ theme, only the close button shows up. Using system title bar and borders will make all the buttons appear, but I really want to use the theme because the system title bar makes the top bar too thick. Logging out and back in didn't fix it, and I tried reinstalling Chrome, but the problem persists.

Load balancing on Ubuntu Server

- by SabreWolfy

I have Ubuntu 10.04.4 server (32-bit) installed on a headless quad-core machine with 2GB RAM. I'm running a command-line analysis which is analyzing a large amount of data, but which does not require a large amount of RAM. The tool does not provide any multi-threading, so the CPU load is sitting at 1.00 (or sometimes just a little over). I ran top and pressed 1 to see the load on each of the cores and noticed that "Cpu1" is always running at 100%. I thought that the load would be distributed between the cores, rather than loading one core all the time. I'm sure I've seen this load-balancing behaviour before in Ubuntu or Debian Desktop versions. Why would the Server edition work differently? The analysis will likely take several hours to run, so loading one core at 100% for many hours while the other 3 remain idle is surely not the best approach?

Radeon HD5670 hangs after login

- by pKaresz

Thanks in advance for your advices. I installed, Ubuntu 12.04 today, on my PC with a Radeon hd5670 graphics card. The first error I encountered, (just like the first time Unity came out - after witch I waited to try Ubuntu again until now) is, that it hanged after login at the desktop wallpaper, with only the mouse cursor. Well actually the first problem was with the live CD, but I managed to install it, using the install now, not the try now. Live CD has the same problem, as after install. So, after installing and getting the error, I searched of course before asking this:) I found this: Ubuntu hangs at purple screen The accepted answer there helped me to get to this. (note, that the below picture is a screen taken from a working desktop, and then erased the parts that don't show on mine.) Note that there is nothing at the top except the brown bar. No shutdown button, no nothing. The system hangs, I can't click on anything, I can only wiggle around with my mouse XD

How can I have only two specific keyboard layouts in my system without 'us'?

- by ??O?????

I want only two keyboard layouts in my system: us altgr-intl (USA International (AltGr dead keys) ) and gr (Greece), so this is what I've selected in System ? Preferences ? Keyboard ? Layouts. However, every time I begin a new Gnome session (reboot, logout/login), the us keyboard layout is automatically inserted at the top of the list. I created a small script called fixlang that ensures the desirable result: layouts='[us altgr-intl,gr]' # tab between us and altgr key=/desktop/gnome/peripherals/keyboard/kbd/layouts active_layouts="$(gconftool -g $key)" if [ "$active_layouts" != "$layouts" -o "$1" == -f ] then gconftool -t l --list-type=str -s $key "$layouts" fi which I run on login. However, this is a kludge. How can I ensure that Gnome does not mess with my keyboard layout selection?

How do I stop Banshee from putting a notification in the panel for every song?

- by Dave M G

As a playlist or internet radio station plays, a notification pops up in the top right corner every time the song changes. I can't find any way either within Banshee or settings in general to stop this. How do I stop Banshee from putting a notification in the panel for every song? Further, can I stop Banshee from outputting any notifications at all? Update: I tried going into Banshee ? Edit ? Preferences ? Extensions, and disabled the Sound Menu Integration, but this does not seem to stop notifications.

Gnome 3 panel and menus are all gone?

- by Hannes

I am running Ubuntu 11.10 using gnome 3 shell. I have set my pc to automatically log into gnome shell so I do not see the login screen. Today I installed some updates and now the gnome panel is gone. When my pc logs in I ONLY see the background. There are no menus, nothing! Even the exit, minimize and maximise buttons in the top tight corner of the windows are gone. Also, alt+f2 also does not work. Any ideas how to fix this? I have a Nvidia Geforce 7900GTO with the Nvidia proprietary drivers installed. I have also used the recovery mode and removed some packages that apparently were broken. Still does not work.

Alternatives to multiple sprite batches for achieving 2D particle system depth

- by Ergwun

In my 2D XNA game, I render all my sprites with a single sprite batch using SpriteSortMode.BackToFront and BlendState.AlphaBlend. I'm adding a particle system based on the App Hub particles sample. Since this uses SpriteSortMode.Deferred and BlendState.Additive, I will need to have two SpriteBatch.Begin / SpriteBatch.End pairs: one for 'regular' sprites, and one for particles. In my top-down shooter, If I want to have explosions appear under planes, but above the ground, then I believe I will have to have three Begin/End pairs, first to draw everything under the explosions, then to draw the explosions, then to draw everything above the explosions. If I want to have particle effects at multiple different depths, then I'm going to need even more Begin/Endpairs. This is all easy to code, but I'm wondering if there is an alternative way to handle this?

WPF Release History : Q2 2010 Beta (version 2010.1.0609)

Q2 2010 Beta New Controls: RadTreeListView As you have probably already noticed we started a major new initiative for completely re-writing the TreeListView control. Our first attempt (back in 2009) proved that our users are mostly interested in a TreeListView control that is based on the GridView control rather then the TreeView. Therefore, we decided to completely rebuild the control and the result is that the TreeListView now combines the powerful data-driven features from RadGridView with...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

UppercuT – Custom Extensions Now With PowerShell and Ruby

Arguably, one of the most powerful features of UppercuT (UC) is the ability to extend any step of the build process with a pre, post, or replace hook. This customization is done in a separate location from the build so you can upgrade without wondering if you broke the build. There is a hook before each step of the build has run. There is a hook after. And back to power again, there is a replacement hook. If you dont like what the step is doing and/or you want to replace its entire functionality,...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

When Your ASP.NET MVC Custom Error Doesn't Render...

You've put [HandleError] on your controller and you've set <customErrors mode="On"> in the web.config file. So why do you still see the yellow screen of death? I've heard various wrong explanations for this phenomena, including "it only works under IIS" and "it only works in release mode". But the custom error view does work in debug mode and it does work with the Visual Studio WebDev web server.

IPTV World Forum : vingt décodeurs TV fondés sur Qt illustrent les différentes facettes du framework (déclaratif, Web, widgets)

Qt y est mis à l'oeuvre à toutes les sauces : de plus en plus de fabricants prévoient d'utiliser Qt Quick pour préparer des interfaces innovantes ; d'un autre côté, les télécoms et opérateurs de télévision numériques préfèrent les interfaces HTML5 avec Qt WebKit (cela sans compter ceux qui utilisent les interfaces plus classiques en C++).

RadCaptcha for ASP.NET AJAX audio feature available in Q1 2010

Now that the Q1 2010 release is here, I want to bring your attention to a cool new feature in our RadCaptcha control for ASP.NET AJAX - audio support. Head on over to our online demos to see the feature in action. Enabling this on an existing CAPTCHA is easy - you just need to set the CaptchaImage-EnableCaptchaAudio property to true. Adding this feature to your site will allow blind or partially sighted people to use it as well. The audio support presents some very interesting possibilities for people who like to customize things. For example, you can replace the original audio files that come with the control (stored in the ~/App_Data/RadCaptcha/ folder in your web application) and add some custom ones - instead of hearing simply "alpha", you can make the control ask "enter the third letter in the word boat". You can also make it speak in ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?
