• OpenGL programming vs Blender Software, which is better for custom video creation?

  - by iammilind

  I am learning OpenGL API bit by bit and also develop my own C++ framework library for effectively using them. Recently came across Blender software which is used for graphics creation and is in turn written in OpenGL itself. For my part time hobby of graphics learning, I want to just create small-small movie or video segments; e.g. related to construction engineering, epic stories and so on. There may be very minimal to nil mouse-keyboard interaction for those videos, unlike video games which are highly interactive. I was wondering if learning OpenGL from scratch is worth for it or should I invest my time in learning Blender software? There are quite a few good movie examples are created using Blender and are shown in its website. Other such opensource cross platform alternatives are also welcome, which can serve my aforementioned purpose.

• Good text editor for Ruby on Rails programming?

  - by Andrew

  I'm trying to find a text editor that I can use for doing Ruby on Rails development. I have been using TextMate on my Mac and would love to find something that even comes close to that experience. My Ubuntu laptop is a little old, and doesn't have a lot of memory, so I need something lightweight. I don't need/want a bloated IDE because the performance on my slow laptop would be terrible. It would be nice if this text editor had: Syntax highlighting A project/file browser view to be able to open files in my project Keyboard shortcuts (don't need them as much)

• Displaying a list of Items in a WPF form using XAML

  - by Dave Colwell

  Hi guys, I am attempting to display a list of items (the style and controltemplate for these items are defined elsewhere) and i want to be able to add/remove as many as i want to. As i do not have infinite screen realestate I am displaying these in a ListBox control. This is the screen i have to date: What is going to happen is this. When i click the New button, i want the item to appear in the outlined area. So now for the problem: I want, when i click the New... Button, a new item to appear in the ListBox (outlined). Is it possible to do this using XAML? I am trying to work on seperating the business logic from the interface, so if there were some way to acheive this in XAML i would appreciate it. If not,can i use the custom templated item i have created in C# so that it will appear as the template specifies in the list box instead of like a normal ListBoxItem Thanks in advance!

• Is it possible to get the old workspaceswitcher back in the top-panel?

  - by Arne

  I just updated my Ubuntu from 10.04 to 12.04 yesterday and so far I'm very satisfied with it. There is only one thing which is still missing to get back just the same comfort as I had with the previous version. I work on 4 workspaces and would like to have the ability to switch from one to another by just one click. With Gnome there was the possibility to add the workspace switcher to the top-panel next to the system tray and I could easily click on just the workspace I wanted to switch to. Of course there I could switch by using the keyboard shortcuts, but I would like to use the mouse in addition. I don't like using the switcher on the left side because it's much slower. Is it possible to get the old workplace switcher back in the panel at the top?

• CSS : overflow : auto will not work under FireFox 3.6.2

  - by Michael Mao

  Hello everyone: This is a CSS related question, I got one good answer from my previous question, which suggested to use some CSS code like overflow:auto together with a fixed height container. And here is my actual implementation : on uni server Please follow the instructions on screen and buy more than 4 kinds of tickets. If you are using IE8, Opera, Safari, Chrome, you would notice that the lower right corner of the page now has a vertical scroll bar, which scrolls the content inside it and prevent it from overflowing. That's what I want to have in this section. Now the problem is, this would not do in FireFox 3.6.2. Am I doing something not compliant to the CSS standard or FireFox has its own way of overflow control? You can inspect the elements on screen, and all controlling functions are done in one javascript using jQuery. All CSS code are kept in a separated file as well. According to the professor, FireFox would be the target browser, although the version was set to 2.0...

• How do I create an ImageView in java code, within an existing Layout?

  - by Dan T

  I'm looking for an easy way for the user to see how many drinks they've had for a BAC calculator. PICTURE OF THE APP, for reference On button press, I would like an image to be added to the screen, directly under the spinner and with left alignment. When I press the button again, I want another image to be added to the screen. So if I pressed the add beer button, a drawable of a beer would appear below the spinner. If I pressed the add beer button again, I want there to be TWO drawables of beers under the spinner, preferably with them being added from the right. (Also, having them reach their width limit, wrapping around, and starting again on the left, but below a full line, would be AWESOME) I can't figure out how to do this. I assume adding a ImageView in code to a relative layout (because it needs to be positioned to the right) would be the best route, but if it's possible in xml I'd be more than happy to use that. Any help?

• Ubuntu 10.10 freezes

  - by albert green

  Hi, I have the following configuration: CPU: amd athlon 64bit Motherboard: Phoenix with awardBIOS v6.0 APIC mode = disabled Video card: GeForce 5500 Sound card: soundblaster live 24bit RAM: 1.5GB Partitions: ext3 32GB where I installed Ubuntu. Swap 500MB. 180GB Fat32 unmounted. contains data only. I installed Ubuntu 10.10 and used the "Additional driver" program to get the nVidia proprietary drivers. The system works for sometime and randomly freezes. The mouse and keyboard are not responding and I am not able to do a SSH. The only solution is pressing the power button. I tried Kubuntu 10.10 and 32/64-bits versions as well. There is nothing in the logs to suggest what the reason might be. Any help will be appreciated. Thanks in advance.

• Configure mounting timeout at boot

  - by René Pieters

  On remotely rebooting a 12.04 machine I found it hanging at the "unable to mount soandso: Skip, Manual Abort? " (That's pretty much how I remember the message) The machine was basically stopped there until I hooked up a keyboard and pressed "s". I can see the rationale for the question, but I'd really like to know where to configure it or turn it off altogether. A mandatory question like this makes sense in a desktop environment but for servers I'd like more flexibility. So where do I fiddle and tweak this?

• Flex: Why does setting scaleX/Y in mxml effect the components size but setting it in actionscript do

  - by ChrisInCambo

  Hi, I'm playing around with the scaleX/Y in the canvas tag and have noticed some strange behaviour. When I set scale in in mxml the width and height of the canvas are adjusted accordingly. For example if I have a canvas like this: <mx:Canvas width="1000" height="1000" scaleX="0.1" scaleY="0.1" /> The canvas now appears on screen to have a width and height of 100 and if inside my creationComplete callback I check the width and height property they are indeed 100. But if I do exactly the same thing except I set the scaleX/Y property from actionscript the canvas on screen appears to have a width and height of 100 as expected, but when I check the width and height property of the canvas they are still at the previous values of 1000. Could anyone help me understand what is going on and also tell me if there is any method that will refresh the width and height values so that they are correct? Thanks, Chris

• Alt Tab with xdotool and xkeybind

  - by Gary

  I'm trying to map alt tab behavior to a mouse button using xdotool in my .xbindkeysrc. What I want to do is map something like "xdotools keydown alt key Tab" release b:7 but by doing this the alt key gets stuck, and it prevents my other mappings from working until I press the alt key on the keyboard. Is there a way to do this without having to press the alt key to get things unstuck? Without keydown it just switches back and forth between two windows, with keydown it behaves like I want (displaying the alt-tab switcher) but the alt key is stuck. Is there a way to unstick the key after using the alt tab switcher using xdotools?

• IPhone UIView:Is it possible to enable userinteraction only on subviews?

  - by Syg

  Hi guys, I created a viewcontroller that displays a button which is used to slide a view onto the screen. The idea is to place for instance three such viewcontrollers onscreen, resulting in three buttons at the bottom of the screen providing navigation. The viewcontrollers get stacked, so to the top one is now overlaying the other views and therefore the other buttons. Only the top viewcontroller's button is working in this situation, where I would like all three of them to be clickable. I tried disabling userinteraction on the view and enabling it on the buttons only, but it looks like the superview settings overrule the subview settings. Any ideas?

• Kiosk Mode Coding in Chromium

  - by Aaron

  I don't know how easy this would be, since I don't know anything about it, but I need an Ubuntu setup where the machine boots up, displays the login for a few seconds allowing a chance to log in as an admin, and then precedes to automatically log in to a user account which directly opens Chromium (any other browser is acceptable) in a kiosk mode where only the web content is visible, all Chromium keyboard shortcuts are disabled, and all but a select few websites are blocked, redirecting back to the home page after an "Unauthorized web page" warning comes up if the URL constraint is violated. Is it possible to code a kiosk setup like this, or am I asking for too much? If I'm simply uninformed, and there is already much documentation on anything like this, please redirect me to an appropriate page. If you can code or set up something like my description, please reply with step-by-step instructions, and instructions on how to modify the elements of the kiosk mode. Thank you in advance for any help. (Note: I'm currently using Ubuntu 10.04, but any distribution would work.)

• Minimum brightness level is brighter than the levels just above it

  - by greggory.hz

  I'm using a macbook pro 8,1. When I use the brightness keys on the keyboard, decreasing the brightness works until it reaches the lowest brightness level. At that point (when on the lowest level), the brightness is something like 70 or 80% instead of 0-10% (or whatever it usually is). All the other levels are fine. How can I adjust/calibrate these brightness controls? PS: I'm currently using 12.04 but I've had the same issue no later than 11.10 (and I'm fairly confident it was present in 11.04 as well). UPDATE: If I go to System Settings and select "Brightness and Lock" the exact same thing happens, but there is more fine grained control of the brightness. It goes to completely black when the dial is about 10% from the left edge. When it passes that point, anywhere inside that left 10% appears to be about 70 - 80% brightness (there's no change regardless of where the dial is in this section).

• flex3 Format date without timezone

  - by Maurits de Boer

  I'm receiving a date from a server in milliseconds since 1-1-1970. I then use the DateFormatter to print the date to the screen. However, Flex adds timedifference and thus it displays a different time than what I got from the server. I've fixed this by changing the date before printing to screen. But I think that's a bad solution because the date object doesn't hold the correct date. Does anyone know how to use the dateFormatter to print the date, ignoring the timezone? this is how I did it: function getDateString(value:Date):String { var millisecondsPerMinute:int = 1000*60; var newDate:Date = new Date(value.time - (millisecondsPerMinute*value.timezoneOffset)); var dateFormatter:DateFormatter = new DateFormatter(); dateFormatter.formatString = "EEEE DD-MM-YYYY LL:MM AA"; return dateFormatter.format(newDate); }

• Are large include files like iostream efficient? (C++)

  - by Keand64

  Iostream, when all of the files it includes, the files that those include, and so on and so forth, adds up to about 3000 lines. Consider the hello world program, which needs no more functionality than to print something to the screen: #include <iostream> //+3000 lines right there. int main() { std::cout << "Hello, World!"; return 0; } this should be a very simple piece of code, but iostream adds 3000+ lines to a marginal piece of code. So, are these 3000+ lines of code really needed to simply display a single line to the screen, and if not, do they create a less efficient program than if I simply copied the relevant lines into the code?

• UIScrollView content to track a CAKeyFrameAnimation along a path

  - by CMLloyd

  In my App I have a full-screen UIScrollView where the content is a UIImageView containing a map image which is about 2000px square (i.e. larger than the UIScrollView). Currently, I plot a path across the map and animate a "beacon" image along it using a CAKeyFrameAnimation, which works great. What I would like to be able to do is to make the UIScrollView content move with the animation in such a way as to keep the beacon image in the centre of the screen (giving the user the impression of tracking along the path). Any suggestions on how I might achieve this?

• Visual Artifacts in Visual Studio 2010

  - by Simon Chadwick

  I'm using VS 2010 on Windows Server 2003, running on a Dell Inspiron 9400 laptop. VS 2010 runs fine, except for persistent and random screen re-drawing issues. Samples of these are here. These artifacts occur as the mouse moves over items that highlight on a mouse-over event, while scrolling, and when switching tabs. VS 2008 has non of these issues, so I assume that it is related to VS 2010's use of WPF. Could it be that my video card or driver is not up to the task of rendering WPF? Some other WPF applications (not Silverlight) also have some of these screen repainting problems. I have tried a variety of settings in System Properties--Advanced--Performance Options--Visual Effects, and in the related "Advanced" tab, Processor Scheduling is adjusted for best performance of programs. Many thanks for any suggestions!

• Programming on Leopard for iPhone OS 3.1.3

  - by Blank6

  Hey, I got Leopard with XCode 3.1 and SDK 3.0, when opening the organizer and trying to debug on my ipod I received "The version of iPhone OS on "..." does not match any of the versions of iPhone OS supported for development with this copy of xCode...". It tells me with my xCode I can only develop for iPhone OS 3.0 or less, so I downloaded the new xCode + SDK installation bundle, knowing the SDK can't be installed on Leopard. In the installation it tells me "If you don't want to install the SDK, press disagree", and so I did, but in the next screen he forces me to choose a drive for the SDK, and then says "you can't install the SDK on leopard system", and I can't pass this screen. My question is: is it even possible to program on Leopard for iPhone OS 3.1.3? I really want to debug my apps on my iPod (framework 3.1.3, 3G) Thanks ahead!! By the way: I can't so simply upgrade to snow leopard because it's a hackintosh, so I prefer a different way..
