• Is there animation software available for Ubuntu?

  - by Robert Low

  Is there commercial-grade computer animation software available for Ubuntu, similar to the professional software sold for the Windows operating system? This question goes out to those of you who may be using such software professionally. My daughter recently graduated from the Art Institute of Seattle, and needs to put together an animation portfolio in order to interest employers in the field. As you know, such software is usually provided by the employer and the costs are high - several thousand dollars. I suggested that she investigate Ubuntu as a possible way to acquire the tools she needs. But, since I have no idea what might be available, either as open source or proprietary animation software, I am reaching out to the Ubuntu community for help in the hope someone who is using such software can help her. Thank you for reading this post, and for any information you might have.

• Animate multiple entities

  - by Robert

  I'm trying to animate multiple(3) entities using one model(IQM format). It's working but performance is really bad because I'm calling animate function for each entity in my game loop (I think problem is there). What's the best way to animate multiple entities (with different animation ofc) in OpenGL? I think I can try build one VBO / entity for better performances but I don't think it's the best way to do it.

• On developing deep programming knowledge

  - by Robert Harvey

  Occasionally I see questions about edge cases and other weirdness on Stack Overflow that are easily answered by the likes of Jon Skeet and Eric Lippert, demonstrating a deep knowledge of the language and its many intricacies, like this one: You might think that in order to use a foreach loop, the collection you are iterating over must implement IEnumerable or IEnumerable<T>. But as it turns out, that is not actually a requirement. What is required is that the type of the collection must have a public method called GetEnumerator, and that must return some type that has a public property getter called Current and a public method MoveNext that returns a bool. If the compiler can determine that all of those requirements are met then the code is generated to use those methods. Only if those requirements are not met do we check to see if the object implements IEnumerable or IEnumerable<T>. That's cool stuff to know. I can understand why Eric knows this; he's on the compiler team, so he has to know. But what about those who demonstrate such deep knowledge who are not insiders? How do mere mortals (who are not on the C# compiler team) find out about stuff like this? Specifically, are there methods these folks use to systematically root out such knowledge, explore it and internalize it (make it their own)?

• How a graphic designer can get into game programming?

  - by Robert Valdez

  I'm a graphic design student hoping to pursue a career as a video game artist. However, I want to do some game development as a hobby. I'd like to develop games for the desktop or mobile phones. The only programming experience I have is that I took an intro to programming with java class in which I learned how to make web applets using java's swing library. It was awful. I think the only things I took from the class was what OOP is and how to work with variables and data types and some methods. I also learned some actionscript myself which was fun unfortunately my flash tutorial expired and it's too expensive to buy;( What I was looking to do is learn one programming language and build a game with it without having to go through so many hoops and with minimum cost. If it's possible. I would love to learn C++, but I read it's not best for a beginning programmer. What programming languages or maybe software kits/platforms would you recommend?

• Using Ubuntu with a dial-up connection

  - by Robert Heller

  Is it possible to install Ubuntu on a machine with only a dial-up connection? That is, does the Ubuntu install CD come with everything needed to set up an Internet connection using a dial-up modem (I have a USRobotics Courier V.Everything connected to a RS232 port on a Lava Quattro-PCI). I presently run CentOS (5.9), which does include support for dialup Internet access out-of-the-box (all of the modules for dialup are on the distro DVD). When I ran the UBuntu CD (12.04.1 desktop), there was no sign of dial-up Internet support. Am I faced with a chicken or egg problem?

• Companion Book for Cormen

  - by Robert S. Barnes

  I asked this question on Stackoverflow and they suggested it was more appropriate here. I"m taking a course soon based on the first fourteen chapters of Cormen's Introduction to Algorithms. The course is based on a translation of the 2003 edition. I have two questions: Is it recommended to get the newer 2009 edition and what are the differences? Can anyone recommend a good companion text which has more worked problems and less, "this clearly works" type explanations?

• Using IE 9 as my primary browser

  - by Robert May

  With the release of Internet Explorer 9 RC the browser looks to be in a usable state.  So far, my experience has been positive. However, one area where I am having problems is when people are using the jQueryUI library.  Versions older than 1.8 cause IE 9.0 to be unable to drag and drop.  This is a real pain, especially at sites like Agile Zen, where dragging and dropping is a primary bit of functionality. Now that IE 9 is a release candidate, we’ll see how quickly these things improve.  I expect things to be rough, but so far, I’m really liking IE 9.  There’s more real estate than Chrome (it’s the tabs inline with the address bar) and its faster than Chrome 9.0 and FF 3.6.8 (as tested on my own machine). The biggest drawback so far is that because IE has been so badly behaved in the past, sites expect it to be badly behaved now, which is breaking things now. Technorati Tags: Internet Explorer

• Performing a clean database build with MSBuild part 2

  - by Robert May

  In part 1, I showed a complicated mechanism for performing a clean database build. There’s an easier way.  The easier way is to use the msbuild extension tasks out on codeplex.  While you’ll still need to forcibly take the database offline (ALTER DATABASE [mydb] SET OFFLINE WITH ROLLBACK IMMEDIATE), the other msbuild tasks more easily allow you to create and delete the database.  Eventually, I’ll post an example.

• The Mac Tax

  - by Robert May

  One of our users was having difficulties with their mac and using some web software.  I decided to go peruse the landscape and see how much of a premium people were paying for their macs.  I priced out a Dell and a Mac from their websites.  I tried to get them as close to the same configuration, from a hardware standpoint, as I could.  I found the following: Apple Macbook Pro   Dell XPS 17 There are several important differences in the hardware: The mac doesn’t have a blueray player, but the dell does. The mac has a slightly slower processor. The mac claims to have a better battery, but doesn’t list the specifics, so there’s no way to tell. The mac doesn’t list the video card stats, so there’s no way to tell how comparable they are, but they’re probably close. The mac doesn’t come with any additional software.  No iWorks, iPhoto, etc.  They were left to their default of None, so arguably, the Dell is more functional out of the box. Other than changing the hardware specs to be close, all other configuration options were left at their default. So riddle me this, Batman:  Why do people buy Macs?  I have several dev buddies that own them, but I can’t justify the cost.  First, most of them load bootcamp and/or parallels at extra cost to run windows 7 and windows apps.  The hardware isn’t as good.  The price is almost twice as expensive. How do you justify the premium price? Technorati Tags: General

• install to USB without touching windows MBR

  - by Robert

  I would like as full of an install as possible (most notably no casper, just straight on the drive) on a USB stick, but I'm not allowed to touch the current configuration of the computer I'll be running it on at all (except of course changing the boot options to boot from usb). Most guides I read are about getting a live install with persistence on USB, or (I think) still replace the MBR with GRUB. Is there any way to combine the two, and not touch the underlying system?

• Why I LOVE Dell

  - by Robert May

  We recently ordered a laptop for an employee.  It was delivered yesterday and we realized it had no web cam and wasn’t the 1080p resolution.  He wasn’t happy. So, this morning, I sent an e-mail to our rep and asked him what we could do.  Within an hour or two, he called me, arranged a replacement laptop with the corrected specs, set up a return and had everything arranged and charged us only for the difference.  No pain, no silly questions.  We won’t loose use of the laptop either.  The return and the new laptop will overlap so that we can just pack up the old laptop in the box of the new one, slap some labels on and away we go. This has been my experience with Dell over the past 10 years.  Their corporate service has always been fantastic, and it’s made me a huge fan.  Keep up the good work, Dell! Technorati Tags: Dell

• How to integrate Pidgin and Evolution into the message indicator?

  - by Steven Robert Chetwynd

  I upgraded to 12.10, I was using Unity 2d, but as it no longer exists I moved to gnome classic, something in the upgrade seems to have change the message indicator in the "Indicator Applet Complete". How do I integrate Pidgin and Evolution into the message indicator, there is only a button to launch Pidgin, but a new message does not change the colour of the icon or show up in the dropdown part. Also when minimizing Pidgin it minimizes like a normal window instead of minimizing to the applet. There is nothing in the menu for Evolution at all.

• What kind of hosting do I need?

  - by Robert Smith

  I migrated this question from serverfault. Hopefully this is the appropriate place. I have been trying to answer this question but I haven't found an specific answer to my situation. As I want to pay for what I need, I thought I could get a good answer here. I have a custom made forum (rather than a built-in forum like the ones you can find in plugins, e.g. WP-Forum or phpBB type of software) in Django. I don't want to use Apache and modwsgi because it's usually very memory-hungry and I can't afford a big server. I prefer a combination of nginx and gunicorn which I think is very efficient (maybe you can also tell me what you think about that). I'm expecting to receive 10,000 to 20,000 visits each month with 15,000 to 30,000 page impressions. I have reviewed some cloud services like Amazon EC2 or Rackspace and other more traditional services (Linodo). This site won't use videos or big images and I certainly don't need a huge amount of bandwidth (200GB would be definitely too much). I need shell access so shared hosting is out of the question. What do I need to run a website like that without problems? What about RAM? 256MB would be enough (that's the amount of RAM offered by small instances in Amazon and Rackspace)? Do you know of any alternative to those I mentioned? If you need more information to provide a useful answer, please don't hesitate to ask. By the way, I was told that Linodo is not all that different to Amazon EC2 but this website is supposed to work 24/7, so I can't take advantage of Linodo's flexibility regarding creating and deleting instances. Thanks in advance.

• A lot of 408 errors in apache logs - how to prevent them?

  - by Robert Grezan

  I see a lot of 408 errors in my apache2 logs. I increased RequestReadTimeout and KeepAliveTimout but errors are still there. The errors look like this: xx.xx.xx.xx - - [05/Dec/2012:19:33:56 +0100] "-" 408 4561 "-" "-" xx.xx.xx.xx - - [05/Dec/2012:19:33:56 +0100] "-" 408 4561 "-" "-" I heard that these errors are related to Chrome optimization and some users did reported our site returning 408 internal error. It is interesting that we get two 408 error from same IP in sequence then it that IP start working.

• Is there a way to change the root password while still logged in? I did something bad by accdient -_-

  - by Robert

  So I was trying to add my printer, and I wasn't able to make any changes due to the fact that cups was not accepting my root password. I was Googling some changes and trying to fix the problem when one of the commands CHANGED MY SUDO PASSWORD! Can someone please tell me which one of these is the culprit? I was trying to these commands: cat /etc/group | grep root cat /etc/group | grep myUserName usermod -a -G lpadmin myUserName sudo usermod -a -G lpadmin myUserName sudo gedit /etc/cups/cupsd.conf lppasswd -a myUserName lppasswd -a root sudo lppasswd -a myUserName I think it was this one, but I know which passwords I put in! There was nothing which I typed in besides my strong password or my easy temporary password. Unless I made a typo... please no. restart cups sudo password root This is so not cool, I was just trying to add a printer :'( Please help my stupidity!

• Heightmap and Textures

  - by Robert

  Im trying to find the "best way" to apply a texture to a heightmap with opengl 3.x. Its really hard to find something on google because tutorials are olds and they're all using different methods, im really lost and i dont know what to use at all. Here is my code that generates the heightmap (its basic) float[] vertexes = null; float[] textureCoords = null; for(int x = 0; x < this.m_size.width; x++) { for(int y = 0; y < this.m_size.height; y++) { vertexes ~= [x, 1.0f, y]; textureCoords ~= [cast(float)x / 50, cast(float)y / 50]; } } As you can see, i dont know how to apply the texture at all (i was using / 50 for my tests). Result of that code : I would like to have something very basic like : (you can find more pics in his blog) Edit : my texture size is 1024x1024.

• ubuntu-support-status error

• What is the program "Additional Drivers" (jockey-gtk) talking me about?

  - by Robert Vila

  The program says: "No proprietary drivers are in use on this system" But it doesn't say if it is talking about graphical drivers only or what. Then, it lists two drivers: NVIDIA accelerated graphics driver (version 173). NVIDIA accelerated graphics driver (version current) [recomended] Both have exactly the same description. What is the difference then? When I select the 1st one, it says: "This river is not activated",and there's a button to "activate" it. When I select the 2nd one, it says: "This river is activated but it is not currently in use", and the button is to "remove". So which one is in use? Why or what for should I have activated (enabled) and not in use? If it is in use it is activated? What is the difference between activate and remove? and what is the relationship between installed, activated, in use, enabled and removed, disabled, inactive and not-installed? Why can I activate the inactivated and remove (but not deactivate) the activated that is not in use? All this is very puzzling... What other drivers can I use for an Apple MacBook pro 3,1 and how? I see that there's a nouveau and I heard that there was going to be a new open source even better. > -display > description: VGA compatible controller > product: G84 [GeForce 8600M GT] > vendor: nVidia Corporation

• Hotel Reservation Request Booking Paypal PHP

  - by Robert

  I'm making a website for a small hotel in php. The hotel owners want a reservation system that uses paypal. They want people to see a calendar and choose a date to make a reservation. If the day has vacancy, they want the user to request booking a room. This would then require the hotel owner to accept the purchase. I have not worked on a project that has this "request to purchase" method of buying with paypal. Is this possible? Does anyone know of an open php system that handles this? THANKS :)
