• Most appropriate diagram for GUI button design?

  - by JustADude

  What is the most appropriate diagram for GUI button design? Specifically, I have numerous buttons that will be changing color based on state information from operator input and input from various subcomponents and sensors. I would like to use UML or some other type of design diagrams to be able to capture the color transition. Some folks have suggested sequence diagrams, but I haven't been able to find any good examples that show how to incorporate this design artifact. I would really like to head in this direction to help developers. Thanks a ton for feedback and insights.

• Multi Monitor Setup Problems

  - by Shamballa

  I have Ubuntu 10.04 LTS - the Lucid Lynx. I have until recently been using a nVida Graphics card (NVIDIA GeForce 9800 GT) with two monitors attached, this all worked fine and dandy. A couple of days ago I bought two new identical LCD monitors for a multi monitor setup and two ATI graphics cards (ATI Sapphire Radeon HD5450). NOTE *All monitors work fine in Windows XP, 2k, Vista and 7 After I had booted into Ubuntu only one display came on, that I kind of expected anyway, then I removed the driver for the nVidia card and downloaded the ATI version which gave me the ATI Catalyst Control Center - in that only two of the displays were showing the third was disabled and showing unknown driver. I enabled the third monitor that stated "Unkown Driver" and had to reboot, upon reboot none of the displays work. I restarted and booted up into recovery mode and from now that is only what I can get into using a failsafe driver. It seems according to the log that a server is already active for Display 0 and I have to remove /tmp/.X0-lock and start again. This is what the log file is saying: Fatal Server Error Server is already active for display 0 if this server is no longer running, remove /tmp/.X0-lock and start again. (WW) xf86 closeconsole: KDSETMODE failed: Bad file descriptor (WW) xf86 closeconsole: VT_GETMODE failed: Bad file descriptor (WW) xf86 closeconsole: VT_GETSTATE failed: Bad file descriptor ddxSigGiveUp: closing log I have tried looking at my xorg.config file but unfortunately I have not really got a clue as to how it "should" be - I have tried regenerating it using this command from a terminal: sudo dpkg-reconfigure -phigh xserver-xorg but that had no effect so I am currently stuck in failsafe driver mode but two monitors are active but are mirroring each other. I hope that this is not to long - looking back I have been going on a bit! but I am just trying to explain as much as I can... I have asked this on Linuxquestions but nobody seems to know either or at least I have not had any responses. Could some kind soul please help explain what I can do from here? I would be eternally grateful. Chris * Update * Removing xorg.conf does nothing other than allowing me to use only two monitors - using the command: sudo aticonfig --initial generates the xorg.conf file below: but does not work either - I just get two monitors...

• windows system (bootloader) partition accidently deleted during multiple installs

  - by S.Y.T.

  After experimenting with multiple variations of backtrack and xbmcbuntu variations of Ubuntu with dual boot successfully, my windows partition became unrecognizable to grub. I used my windows boot CD to try to correct the problem. However, I deleted all partitions except for the NFTS one that contains my old windows install. (And, merged all other ones into that in hopes of getting back to the windows boot loader and out of grub) Now, all I get is a grub command prompt when I try and boot the system (how??? - I thought I deleted grub) And, now the windows boot disc doesn't even recognize the install. I've tried TRK to try and resolve the problem. Though I must admit ignorance in correctly using this utility. I've searched for other answers to this problem. Any help would be much appreciated. S.Y.

• Which is Better: Revo Uninstaller or a Free Alternative?

  - by The Geek

  The results might surprise you! Our friends over at 7 Tutorials did some testing and found that the free IObit uninstaller application actually stacked up pretty well against the paid solution from Revo—though perhaps with a few less features. Note: we’ve always been fans of Revo Uninstaller around here, since it does have a lot of features to help clean up bad apps that the free alternatives don’t have. Either way, the 7 Tutorials article is worth a read.

• Programming to ANSI standards (for engineering)

  - by Jake

  I am currently tasked to write a software to help engineers design standard compliant designs. If there is a bad design, software will report an error or warning. Maybe it's just me, but anyone who has done this should be familiar with the massive amounts of ANSI standards tables like this one: http://en.wikipedia.org/wiki/Nominal_Pipe_Size Computers are, as its name suggest, computing machines, not lookup machines. I feel that feeding formulas into computers and churning out standard compliant designs is much more efficient than doing memory intensive data lookups that are prone to human input errors and susceptible to "data updates". I actually think that there are formulas to calculate all those numbers, but nobody so far could give me that information. Anyone been through this before? What is THE best approach to this? Thanks for sharing.

• How do I find the dependencies for a program before trying to compile it?

  - by Ubuntu_beginner

  I was trying to cross-compile a program for ARM. While compiling I was very much irritated as I had to look for a number of dependencies e.g fatal error: abc/xyz.h: No such file or directory compilation terminated. After ensuring that compiler gets the missing files, when I recompiled, I got same error for about 30 files. I have no idea if that is normal behaviour. If it is normal, is there a method which can help the compiler find the dependencies on its own? If that is not normal, then please explain what I'm doing wrong.

  This is what I am trying to do. I downloaded the latest driver for my VGA from http://www.nvidia.com.

• U1 music shows unknown artist, how can I make it recognize m4a files?

  - by bisi

  Hello all, I am in the process of uploading my music library as a backup to U1, but I figured, why not also enjoy Ubuntu 1 music on my iPhone? With a few difficulties to start, the upload is now in progress, but I've noticed that there is a huge percentage of files in the unknown artist folder, and I believe it is all of my m4a files. They play fine, but without any information. Coming from an iTunes background, and having bought the majority of my music on the iTunes store, I wonder how I could make this work, easily? I am on Maverick (afaik), but About Ubuntu shows 11.04. I use Banshee as my music manager, and I monitor my sync using Ubuntu one preferences, ubuntuone-indicator and magicicada. The total file size of my music folder is 38.9GB. Thank you for your help!! And apologies if I couldn't find a thread where this was already covered...

• Using packages (gems, eggs, etc.) to create decoupled architectures

  - by Juan Carlos Coto

  The main issue Seeing the good support most modern programming platforms have for package management (think gem, npm, pip, etc), does it make sense to design an application or system be composed of internally developed packages, so as to promote and create a loosely coupled architecture? Example An example of this would be to create packages for database access, as well as for authentication and other components of the system. These, of course, use external packages as well. Then, your system imports and uses these packages - instead of including their code within its own code base. Considerations To me, it seems that this would promote code decoupling and help maintainability, almost in a Web-based-vs.-desktop-application kind of way (updates are applied almost automatically, single code base for single functionality, etc.). Does this seem like a rational and sane design concept? Is this actually used as a standard way of structuring applications today? Thanks very much!

• Rules of Holes #3: A Better Shovel is NOT the Answer!

  - by ArnieRowland

  You stopped digging. You looked around and saw that you were still in the Hole. You needed to get out. AHA! Problem solved, you thought. You'll just get a better and more efficient shovel! I regret to tell you that the Third Rule of Holes applies: Switching to a more efficient shovel is unlikely to help you get out of the Hole . Yes, your resumed digging may be faster, more directed, and even well planned and articulated. But you will still be in the Hole, and digging. And that's just not the solution....(read more)

• Server costs and back loading for mobile devices

  - by user23844

  A company approached me to design an MMO for the mobile platform and I have the perfect idea for them. My question is how much would a server for a FTP game that has both a PVE element and PVP cost? Also do you think that it would be better or is it even possible to back load the data onto the phones (trying to come up with some interesting way to back up the data in case of emergency). I don't want the game to be totally online reliant (I want to appeal to not only phone users but also iPod touch users) and for there to be an offline mode. If you can't tell this is my first game besides simple projects I've done on the side. Any help would be greatly appreciated.

• Maya and Game Engines (i.e. Environment Testing)

  - by DiscreteGenius

  What does it mean if I'm designing an environment and I want to test it in the game engine, to see what its like to "run" [or fly] around my environment? I heard an instructor say that exact thing in a Maya training video and I'd like to know more about "How Game Engines and Maya are related to each other." He stated this would be done to see how things look in "size" (e.g. I assume he meant: 'How big is the cathedral, bridge, wall, building, etc.'). I've tried to research such information but it's too complicated, and detailed. I just want a simplistic response to my query. Thanks to everyone willing to help and not criticize my question.

• ubuntu will not connect after restart

  - by nicedoggy

  Firstly, I hope this hasn't been covered elsewhere, I have searched but haven't found this particular problem. I updated to 12.04 a while back and though I now thoroughly regret that decision, I'm able to live with 12.04 and all it's odd little quirks. The one problem that I would like to fix is this. I have a small network, using a router modem which stays on most of the time. If the computer is switched off, when it is switched on again I have to click on "auto Ethernet" in "Network" in order to get on the internet. It then works fine. Previous versions just connected automatically on restart. When 12.04 says it is unable to connect, other computers on the network are able to connect. Thanks for any help.

• MacMini (running Ubuntu 14.04) loses wlan connection when uploading larger files (several 100 mb) via ownCloud

  - by ManekenT

  I installed Ubuntu 14.04 on an old MacMini with the intention of running it as a homeserver. Additionally I installed ownCloud and tried to sync some files both from a laptop running elementaryOS and a desktop running windows 7. Syncing smaller files workes like a charm (4000 files at <10mb each) but when it comes to bigger files (1 GB ubuntu iso e.g.) the upload failes after 20-100mb. I can't ping the server anymore and the server can't ping me. It still shows up in our router as connected though. Disconnecting and reconnecting the wlan connection fixes the issue until the next attempt at syncing. Edit: I also had to install the wlan driver with this manual: https://help.ubuntu.com/community/MacBookPro8-2#Wireless
