• How do I consistently activate USB speakers

  - by Andrew.Healy

  I have a pair of Ricco USB speakers. As these are external, I sought to use them with 11.10. They are recognised by 'aplay -l' and Pulseaudio- I have selected them, but, have to reset the volume, every time I log on. I can also only recieve feedback and sound from apps and programs- like Kaffeine- on this boosted volume- I cannot get System Sounds, like logon or logoff. I have tried the alsamixer install that used to work, to no effect. Is their an app that I should be trying or is this feat impossible ? I have tried to delete all the files in .pulse and rebooting or just deletion of the entire .purge directory, as Michael K suggested- neither work as the directory is automatically rewritten on reboot. Ideas?

• Not using nofollow for UGC links

  - by Noam

  My site contains many links that were user generated so I've added a rel=nofollow to them. I'm considering removing that tag at least partially, as these are most of my outgoing links and I've come to understand it isn't a good SEO sign to not have outgoing followed links. Although these are external sites, I have some data on the popularity and categorization of these sites. I'm trying to decide between two options: Removing the nofollow link for popular sites in most categories. Removing the nofollow for links that are in specific categories that represent the categorization I would like to achieve for my site. For example if this is a site about Basketball only remove the nofollow for links that are from sport sites. As these are both not exactly natural approaches, can this hurt me? Which option would you recommend?

• Maximized Office 2007 gets cut off on multi-monitor setup with different resolutions

  - by Adam M-W

  I've got an external monitor plugged into my laptop that I like to use for typing up documents, but I've noticed that when Word is maximized it gets cut off at where the primary monitor's bounds are. Is this a bug in Wine (i'm using version 1.3.32), or with my Window Manager (metacity with compositing enabled, version 2.34.1), with my graphics drivers (nouveau) or something else? I know that I can fix it by unmaximizing (it doesn't get cut off and I can resize to the entirety of the second monitor), but it keeps on maximizing itself as it (rightly so) knows that it should be taking up the entire screen. I don't really want to use the "Emulate a virtual desktop feature", I would prefer to find the source of this issue.

• Implementing a FSM with ActionScript 2 without using classes?

  - by Up2u

  I have seen several references of A.I. and FSM, but sadly I still can't understand the point of an FSM in AS2.0. Is it a must to create a class for each state? I have a game-project which also it has an A.I., the A.I. has 3 states: distanceCheck, ChaseTarget, and Hit the target. It's an FPS game and played via mouse. I have created the A.I. successfully, but I want to convert it to FSM method... My first state is CheckDistanceState() and in that function I look for the nearest target and trigger the function ChaseState(), there I insert the Hit() function to destroy the enemy, The 3 functions that I created are being called in AI_cursor.onEnterframe. Is there any chance to implement an FSM without the need to create a class? From what I've read before, you have to create a class. I prefer to write the code on frames in flash and I still don't understand how to have external classes.

• Why would I want to install node.js in my Rails Application?

  - by Crazy JIm

  Okay guys, I'm super confused. I thought node.js was a sever side framwork, basically the js version of Ruby's Rails or PHP's Zend. However, I'm having some difficulty with turbolinks, and it seems to be the way to fix it is through installing node.js I mean, I don't understand this at all. How can two frameworks work together like this? Also, it's not a gem (that REALLY would have confused me), you have to install node.js it onto your local machine by running (in the case of Ubuntu) sudo apt-get install nodejs Firstly, how does this totally separate framwork have any bearing on rails? Secondly, surely this isn't fixing the problem forever? When you specify a gem in your gemfile, the server knows what external libraries to install. How does the server know to install nodejs?

• Which of VLC's dependencies causes sound device detection?

  - by Raphael

  I am setting up a headless music server based on the minimal Ubuntu image. After having installed the packages openssh-server,pulseaudio, libmad0,flac,liboff0,libid3tag0,libvorbis0a,ffmpeg, mpd,mpc,mpdscribble, paman,paprefs,pavumeter neither my internal soundcard nor the external DAC where detected by pulseaudio, that is pactl list did only list the dummy devices. Several reboots did not change that. The hardware devices are detected properly: ~$ lsusb | grep Texas Bus 002 Device 002: ID 08bb:2706 Texas Instruments Japan ~$ lspci | grep Audio 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Following a hunch, I installed vlc with all dependencies. After a reboot, both devices are detected! ~$ pactl list | grep "Sink: alsa_output" Monitor of Sink: alsa_output.pci-0000_00_1b.0.analog-stereo Monitor of Sink: alsa_output.usb-Burr-Brown_from_TI_USB_Audio_DAC-00-DAC.analog-stereo Now I would like to remove VLC again but keep the devices. The question is: which of the many dependencies of VLC enables proper device detection? And why on earth is it not a dependency of pulseaudio?

  I am using external usb keyboard. I want to disable laptop's internal keyboard using software.

• How do I connect a Nexus 7 to transfer files?

  - by gotqn

  I want to move some files from my PC to Nexus 7. The tablet is connected to my PC's USB port and it is successfully charging. Unfortunately, the PC is not detecting the devices - what I expected is to be shown the Nexus 7 tablet as external devices (like my USB flash memory). As the tablet is connected to the my home internet network, I have checked if it will appear in the "Networks" section but it does not. I am using Ubuntu 12.4 LTS. Is there a easy way to connect the devices to my PC and move some information between them?

• Why is using C++ libraries is so complicated?

  - by Pius

  First of all, I want to note I love C++ and I'm one of those people who thinks it is easier to code in C++ than Java. Except for one tiny thing: libraries. In Java you can simply add some jar to the build path and you're done. In C++ you usually have to set multiple paths for the header files and the library itself. In some cases, you even have to use special build flags. I have mainly used Visual Studio, Code Blocks and no IDE at all. All 3 options do not differ much when talking about using external libraries. I wonder why was there made no simpler alternative for this? Like having a special .zip file that has everything you need in one place so the IDE can do all the work for you setting up the build flags. Is there any technical barrier for this?

• Samsung 305u notebook touchpad not working in Ubuntu 13.10

  - by Pablo Viollier

  I just installed Ubuntu 13.10 on my Samsung 305u notebook. The problem is that the touchpad (cursor and clicking) doesn't work, it does nothing. The only way to fix it is to plug an external mouse, which isn't the optimal. I already checked the system preferences and the touchpad is enabled. I used Ubuntu 13.04 before, and it worked. Then I installed Linux Mint and the touchpad stopped working, that's way I installed 13.10, but now it doesn't work here either. I hope someone can help me.

• GPS feature big on mobile phones, oh yeah, they can make voice calls and text too

  - by hinkmond

  Here's a Web article stating the oh-so-obvious: One of the most useful things a cell phone can do is give you GPS location. See: Cell Phones Give Location Here's a quote: Now, majority of GPS receivers are built into mobile phones, with varying degrees of coverage and user accessibility. Commercial navigation software is available for most 21st century smartphones as well as some Java-enabled phones that allows them to use an internal or external GPS receiver. Wow. That's really big news. (face palm) Next thing we know, the Web site at stating-the-obvious.com, is going to tell us that the Internets will bring us news, sports, and entertainment right to our fingertips. Hinkmond

• Maximize, minimize and close buttons are either not present or not working in Lubuntu

  - by jimirings

  As the title indicates, the maximize, minimize, and close buttons are either not present or not working on my Lubuntu desktop. In fact, it only seems to be Google Chrome that displays the buttons at all, and only the close button works in Chrome, maximize and minimize don't do anything. When I use regular Ubuntu, they're all there just fine but not on Lubuntu. This all seemed to occur after I hooked my netbook up to an external monitor while using Lubuntu. Not sure if that had anything to do with it or not, but it seemed too big of a coincidence to not mention. Any ideas what the cause and a fix might be? Thanks in advance.

• Using a particular font in a commercial game

  - by RCIX

  I'm working on a game I intend to sell, and I want to use this font. The license says: "You may NOT copy or distribute the font outside of the licensed household, company, school or institution. Please ask external contacts who want to use the font to purchase their own license at www.CheapProFonts.com." However, my plans are to use a tool to output a texture using this font to use as a bitmap font in my game. Does this mean I can do so, and sell my game with the font in it?

• Methodology for Documenting Existing Code Base

  - by George Stocker

  I work as part of a team on an existing application that has no inline documentation, nor does it have technical documentation. As I've been working on various bug reports on the application, I've written a sort of breadcrumb trail for myself - bug numbers in various places so that the next developer can refer to that bug number to see what was going on. My question is thus: What is the most effecient method for documenting this code? Should I document as I touch the area (the virus method, if you will), or should I document from each section on its own, and not follow paths that branch out into other areas of the application? Should I insert inline comments where none previously existed (with the fear that I may end up incorrectly identifying what the code does)? What method would you use to accurately and quickly document a rather large application that has no existing inline documentation, nor inline references to external documentation?

• How agile methodologies can be applied in a typical " services " company?

  - by AlfaTeK

  My company is a custom software services company for external clientes, which means our typical project is one in which the contract already states the full budget of the project. Our typical project starts by defining requirements (improving the proposal high-level requirements), then we code the project, test it and ship it. We have an acceptance phase were the client tests the software and in that phase we can usually implement small changes asked by the client, or we charge extra for change requests. In some projects we have intermediate releases so the clients can check the progress of the project and give feedback on it. In summary: something like waterfall... I've followed the "agile" movement for a bit now and I always see it being a good match for a "product" company, or a company building software for an internal client. But are there good stories / advantages on using agile methods in my kind of company/projects? What are your experiences, what do you think about this?

• Volume setting isn't remembered after restart/shutdown

  - by Iulian

  This is my first time here and I'm new to linux and also to Ubuntu. I've installed first version 11.10 and there was some problems with the unity dock and also the problem with the volume not being remembered after restart or shutdown. I'm using dualboot with Windows 7. Ubuntu was installed after windows. I have 2 sound cards. One is onboard, on the motherboard, and the other is external, an E-MU 0404 USB 2.0 sound card. The last one is my primary sound card and I've choosed it as default output sound card. I've upgraded to 12.04 hopeing that this was fiex but even in this version the OS doesn't keep the volume where it was last time. The big problem is that sometimes I forget about this problem and start music and it starts at full volume and soon I think I will die of heart attack. Is there a way to make it remember or at least to tell him to start at a specific volume not at 100%?

• cannot add movie file to pitivi

  - by niku

  when i try adding this movie file to pitivie i get the error as follows (i can play the file in mplayer just fine tho): Problem: An internal error occurred while analyzing this file: Could not find GStreamer caps mapping for FFmpeg codec 'h264', and you are using an external libavcodec. This is most likely due to a packaging problem and/or libavcodec having been upgraded to a version that is not compatible with this version of gstreamer-ffmpeg. Make sure your gstreamer-ffmpeg and libavcodec packages come from the same source/repository. Extra information: gstffmpegdec.c(1336): gst_ffmpegdec_negotiate (): /GstPipeline:Discoverer-file:///media/Data/pitivi/taw2.mkv/GstDecodeBin2:dbin/ffdec_h264:ffdec_h2645 Also, my system language is English, but regional format is set to German. mplayer installed in German, I want it in English tho... Thanks a lot for your help :) I know I'm a noob .

• Will Ubuntu 12.04 work on an Acer Aspire One D257-1682?

  - by Avid

  Is it possible to install Ubuntu 12.04 on an Acer Aspire One D257-1682? I have a disc that I used to run Ubuntu 12.04 on my desktop without incident. When trying to run it on my Aspire One, using an external DVD drive via USB, I get a ton of errors about missing files while it tries to load Ubuntu. I found a list of which versions of Ubuntu to run depending on which Aspire One model you have, but the D257 was not listed at all. I want to have Ubuntu on my Aspire One for coding Java and C++ since I don't have to sit at my desk for hours. Please help! -Avid

• DDD and validation of aggregate root

  - by Mik378

  Suppose an aggregate root : MailConfiguration (wrapping an AddressPart object). The AddressPart object is a simple immutable value object with some fields like senderAdress, recipentAddress (to make example simple). As being an invariant object, AddressPart should logically wrap its own Validator (by the way of external a kind of AddressValidator for respecting Single Responsibility Principle) I read some articles that claimed an aggregateRoot must validate its 'children'. However, if we follow this principle, one could create an AddressPart with an uncohesive/invalid state. What are your opinion? Should I move the collaborator AddressValidator(used in constructor so in order to validate immediately the cohesion of an AddressPart) from AddressPart and assign it to aggregateRoot (MailConfiguration) ?

• Apache2 Unwantingly Allowing Proxy Requests

  - by Kevin

  I'm not sure if this is the right location, but this is fairly urgent. I have completely removed all traces of mod_proxy and the other mod_proxy mods, although the Apache server continues to allow proxy requests. I have restarted numerous times, and have shut down until I can find an answer. I've noticed lots of requests from IPs in and around China to external sites such as free movie downloads and such. I'd like to prevent this from happening. I'll be grateful for any help I get.

• Complete Guide/Tutorials on LWJGL?

  - by user43353

  Dont get me wrong, I finished these tutorials on http://lwjgl.org/wiki/index.php?title=Main_Page. I finished The Basics section, OpenGL 3.2 and newer section, and I looked at the Example Code section. They were great tutorials, and I have looked at the external tutorials as well. I don't know where to go from here, and OpenGL is not my strong point. Some one suggested Learning Modern 3D Graphics Programming, and I didnt learn much. I looked at the port to LWJGL, but the book was on C and I couldn't really understand what the OpenGL meant. I am trying to learn 2D gaming, not 3D. Maybe later. Is there any tutorials that aren't C/C++ heavy and teach you 2D OpenGL?
