• 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?

• How to unmount a virtual cd/dvd in Ubuntu 11.1o

  - by P J Reil

  I'm new to Ubuntu 11.10 and have absolutely no idea what I'm doing. I don't now how but in downloading and fooling around with a virtual cd/dvd program I seem to have inadvertently installed it. I had to shut down my computer for a while and when I re booted it all my files and my setup was gone. I have a brand new 11.10 setup with all the programs installed that I originally had but no files or bookmarks etc.. I'm not sure, but I think I'm running in a virtual cd/dvd. I don't know how to determine if I am or not and can't boot up in my original setup. Can anyone help me?

• OUM is Flexible and Scalable

  - by user535886

  Flexible and Scalable Traditionally, projects have been focused on satisfying the contents of a requirements document or rigorously conforming to an existing set of work products. Often, especially where iterative and incremental techniques have not been employed, these requirements may be inaccurate, the previous deliverables may be flawed, or the business needs may have changed since the start of the project. Fitness for business purpose, derived from the Dynamic Systems Development Method (DSDM) framework, refers to the focus of delivering necessary functionality within a required timebox. The solution can be more rigorously engineered later, if such an approach is acceptable. Our collective experience shows that applying fit-for-purpose criteria, rather than tight adherence to requirements specifications, results in an information system that more closely meets the needs of the business. In OUM, this principle is extended to refer to the execution of the method processes themselves. Project managers and practitioners are encouraged to scale OUM to be fit-for-purpose for a given situation. It is rarely appropriate to execute every activity within OUM. OUM provides guidance for determining the core set of activities to be executed, the level of detail targeted in those activities and their associated tasks, and the frequency and type of end user deliverables. The project workplan should be developed from this core. The plan should then be scaled up, rather than tailored down, to the level of discipline appropriate to the identified risks and requirements. Even at the task level, models and work products should be completed only to the level of detail required for them to be fit-for-purpose within the current iteration or, at the project level, to suit the business needs of the enterprise and to meet the contractual obligations that govern the project. OUM provides well defined templates for many of its tasks. Use of these templates is optional as determined by the context of the project. Work products can easily be a model in a repository, a prototype, a checklist, a set of application code, or, in situations where a high degree of agility is warranted, simply the tacit knowledge contained in the brain of an analyst or practitioner. For further reading on agility, see Balancing Agility and Discipline: A guide fro the Perplexed.

• Will mono be carried forward by upgrading to 12.04?

  - by vasa1

  I plan to upgrade from 11.10 to 12.04 when 12.04 is released. I noticed from my previous experience in upgrading from 11.04 to 11.10, that Synaptic, which was dropped in 11.10, was retained on my system presumably because I upgraded from 11.04 (which did have Synaptic by default) and didn't do a new install. Given that Synaptic was retained, my question relates to mono. According to the list here, I don't have any programs that need mono. (I've just purged Banshee.) If I don't remove mono, will it be carried forward when I upgrade to 12.04 just like Synaptic was? If the suggestion is to remove mono before the upgrade to 12.04, is sudo apt-get purge libmono* libgdiplus cli-common libglitz-glx1 libglitz1 still the recommended way to remove mono-associated material from 11.10?

• Do I have to completely reinstall Ubuntu now that it won't boot?

  - by Dave M G

  I just tried installing software called Teamviewer. It said there was some kind of error with unresolved dependancies. Then I realized I was trying to install the 32 bit version, but I needed to install the 64 bit version. So I tried that, and I got an error saying that Ubuntu needed to do a partial upgrade. I thought that was weird, so I just wanted to abandon installing anything and get out of this. I exited all programs and rebooted, and now I can't get back into Ubuntu. After the GRUB screen I get a black screen and no login options. If I boot into recovery, I get the following screen: I booted up a live CD of 12.04 to see if that could help, but it seems the only option is to completely reinstall Ubuntu. Can I repair this in any way, or is my only option to make a fresh install?

• Geocode multiple addresses

  - by ace2600

  I need to geocode around 200 addresses per request and do around 3,000 request per day. I will be doing this server side using PHP. I have looked at http://stackoverflow.com/questions/98449/how-to-convert-an-address-to-a-latlon, but could not find a way for either Google Maps HTTP Request API or the Yahoo Geocoding REST API (cannot use JavaScript as this is server side) to send multiple addresses. I will be primarily using this to sort addresses based on the coordinates and if the API supports, fill in any missing data for each address. The addresses will be in the United States only. The addresses to geocode will be from user input, so be free form, like "street address, postal code", or "city, state", etc. Accuracy is not too important for the coordinates, say within five hundred feet or so. Is there a free API to handle this? Is there a way to get Yahoo or Google to do multiple locations in a request?

• HTG Explains: How the SmartScreen Filter Works in Windows 8

  - by Chris Hoffman

  Windows 8 includes a SmartScreen filter that prevents unknown and malicious programs from running. SmartScreen is part of Internet Explorer 8 and 9 – with Windows 8, it’s now integrated into the operating system. SmartScreen is a useful security feature that will help prevent bad applications from running, but it may occasionally prevent a legitimate application from running. SmartScreen reports some information to Microsoft, so it may have some privacy implications. HTG Explains: Is ReadyBoost Worth Using?

• GLSL billboard move center of rotation

  - by Jacob Kofoed

  I have successfully set up a billboard shader that works, it can take in a quad and rotate it so it always points toward the screen. I am using this vertex-shader: void main(){ vec4 tmpPos = (MVP * bufferMatrix * vec4(0.0, 0.0, 0.0, 1.0)) + (MV * vec4( vertexPosition.x * 1.0 * bufferMatrix[0][0], vertexPosition.y * 1.0 * bufferMatrix[1][1], vertexPosition.z * 1.0 * bufferMatrix[2][2], 0.0) ); UV = UVOffset + vertexUV * UVScale; gl_Position = tmpPos; BufferMatrix is the model-matrix, it is an attribute to support Instance-drawing. The problem is best explained through pictures: This is the start position of the camera: And this is the position, looking in from 45 degree to the right: Obviously, as each character is it's own quad, the shader rotates each one around their own center towards the camera. What I in fact want is for them to rotate around a shared center, how would I do this? What I have been trying to do this far is: mat4 translation = mat4(1.0); translation = glm::translate(translation, vec3(pos)*1.f * 2.f); translation = glm::scale(translation, vec3(scale, 1.f)); translation = glm::translate(translation, vec3(anchorPoint - pos) / vec3(scale, 1.f)); Where the translation is the bufferMatrix sent to the shader. What I am trying to do is offset the center, but this might not be possible with a single matrix..? I am interested in a solution that doesn't require CPU calculations each frame, but rather set it up once and then let the shader do the billboard rotation. I realize there's many different solutions, like merging all the quads together, but I would first like to know if the approach with offsetting the center is possible. If it all seems a bit confusing, it's because I'm a little confused myself.

• MathType and LibreOffice Math comparison

  - by Agmenor

  In my office my team and I are going to type texts in the future which will include mathematical signs. Two programs are being proposed: LibreOffice Writer + Math or Microsoft Office + MathType. I would like to advocate for the first solution, but I need to know what technical advantages and disadvantages each program has. Compatibility with Ubuntu is an evident and important characteristic for LibreOffice, but could you give some other aspects? As a side question, do you advice any other program, even if not WYSIWYG and thus not my preference in this case?

• looking for a short explanation of fuzzy logic

  - by user613326

  Well i got the idea that basics of fuzzy logic are not that hard to grasp. And i got the feeling that someone might explain it to me in like 30 minutes. Just like i understand neural networks and am able to re-create the famous Xor problem. And go just beyond it and create 3 layer networks of x nodes. I'd like to understand fuzzy till a similar usefully level, in c# language. However the problem is face, I'd like to get concept right however i see many websites who include lots of errors in their basic explaining. Like for example showing pictures and use different numbers as shown in pictures to calculate, as if lots of people just copied stuff without noticing what they write down. While others for me go to deep in their math notation) To me that's very annoying to learn from. For me there is no need to re-invent wheel; Aforge already got a fuzzy logic framework. So what i am looking for are some good examples, good examples like how the neural XOR problem is solved. Is there anyone such a instructional resource out there; do you know a web page, or YouTube where it is shortly explained, what would you recommend me ? Note this article comes close; but it just doesnt nail it for me. After that i downloaded a bunch of free PDF's but most are academic and hard to read for me (i'm not English and dont have a special math degree). (i've been looking around a lot for this, good starter material about it is hard to find).

• Open Grid Engine or Akka/Something more fault tolerant?

  - by Mike Lyons

  My use case is that I have a pipeline of independent, stand alone programs, that I want to execute in a certain order on specific pieces of data that our output from previous pipeline stages. The pipeline is entirely linear and doesn't do anything in terms of alternate paths through the pipe. I'm currently using SGE to do this and it works OK, however occasionally a job will overstep it's memory bounds, fail, and all jobs that require that output data will fail. The pipe needs to be restarted in that case, and it seems that whatever is providing the fault tolerance in akka might solve that for me?

• Unable to uninstall Wine apps

  - by CrunchyNeo

  I recently ran the iTunes 10 installer in Wine and everything seemed to go well. Then, when I tried to run it, it would constantly crash/and the appearance would be glitchy. After looking at the Wine website, it turns out that iTunes 10 has a 'garbage' rating of Wine compatability. Now I'm trying to remove/uninstall iTunes, QuickTime, and the other applications that come default with installing iTunes (such as Bonjour, etc.). However, when I run the 'uninstaller' that wine provides for the programs, it instead executes what appears to actually be the original installer! I've tried deleting all the configuration/data files in my Wine's file-system, but to no avail. Any help is greatly appreciated! Edit1: After re-running the uninstall process and then rebooting, the program (iTunes 10) still remained installed.

• java MainServer gives java.lang.UnsupportedClassVersionError: Unsupported major.minor version 51.0

  - by Paradox

  Compiling is easy but when using java to run the programs, it gives Exception found. I am using Ubuntu 12.04 without internet connections. Also, installed Oracle JDK7 and JRE7. Also did the update-alternatives command on java, javac and javaws. Changed the machine java in /etc/profiles. PATH is pointing to oracle java folder. I did many searches on Google about this topic but each time jdk and jre version are different. Also check version of jdk and jre using java -version and javac - version. Both of them are the same. The system also contains OpenJdk6 and OpenJdk7. So, how do I remove these errors?

But I am looking for free training videos for Vb.Net/webforms and SQL "CRUD", Sql DataBinding videos, runtime designing , runtime databinding and all. Thanking you all in advance. And also I am sorry if this is a repeat question. And one thing which I like to say is why do people go first with winforms when someone says vb.net ? Is there any specific way to say for webforms ? OR how should I say it for web development in VB?

• HTG Explains: How Windows Uses The Task Scheduler for System Tasks

  - by Chris Hoffman

  While you can use the Windows Task Scheduler to schedule your own automatic tasks, Windows also uses it behind the scenes to perform many system tasks – defragmenting your hard disks when you’re not using your computer, for example. You can even modify these system tasks to tweak Windows to your liking – for example, you can change how often Windows creates system restore points. Third-party programs also often use the Task Scheduler for their own tasks. HTG Explains: Why Do Hard Drives Show the Wrong Capacity in Windows?

• my server suddenly crashes every 2 days or so. Programmer has no idea, please help find the cause, here is the top

  - by Alex

  Every couple of days my server suddenly crashes and I must request hardware reset at data center to get it back running. Today I came back to my shell and saw the server was dead and "top" was running on it, and see below for the "top" right before the crash. I opened /var/log/messages and scrolled to the reboot time and see nothing, no errors prior to the hard reboot. (I checked in /etc/syslog.conf and I see "*.info;mail.none;authpriv.none;cron.none /var/log/messages" , isn't this good enough to log all problems?) Usually when I look at the top, the swap is never used up like this! I also don't know why mysqld is at 323% cpu (server only runs drupal and its never slow or overloaded). Solver is my application. I don't know whats that 'sh' doing and 'dovecot' doing. Its driving me crazy over the last month, please help me solve this mystery and stop my downtimes. top - 01:10:06 up 6 days, 5 min, 3 users, load average: 34.87, 18.68, 9.03 Tasks: 500 total, 19 running, 481 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 96.6%sy, 0.0%ni, 1.7%id, 1.8%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 8165600k total, 8139764k used, 25836k free, 428k buffers Swap: 2104496k total, 2104496k used, 0k free, 8236k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4421 mysql 15 0 571m 105m 976 S 323.5 1.3 9:08.00 mysqld 564 root 20 -5 0 0 0 R 99.5 0.0 2:49.16 kswapd1 25767 apache 19 0 399m 8060 888 D 79.3 0.1 0:06.64 httpd 25781 apache 19 0 398m 5648 492 R 79.0 0.1 0:08.21 httpd 25961 apache 25 0 398m 5700 560 R 76.7 0.1 0:17.81 httpd 25980 apache 25 0 10816 668 520 R 75.0 0.0 0:46.95 sh 563 root 20 -5 0 0 0 D 71.4 0.0 3:12.37 kswapd0 25766 apache 25 0 399m 7256 756 R 69.7 0.1 0:39.83 httpd 25911 apache 25 0 398m 5612 480 R 58.8 0.1 0:17.63 httpd 25782 apache 25 0 440m 38m 648 R 55.2 0.5 0:18.94 httpd 25966 apache 25 0 398m 5640 556 R 55.2 0.1 0:48.84 httpd 4588 root 25 0 74860 596 476 R 53.9 0.0 0:37.90 crond 25939 apache 25 0 2776 172 84 R 48.9 0.0 0:59.46 solver 4575 root 25 0 397m 6004 1144 R 48.6 0.1 1:00.43 httpd 25962 apache 25 0 398m 5628 492 R 47.9 0.1 0:14.58 httpd 25824 apache 25 0 440m 39m 680 D 47.3 0.5 0:57.85 httpd 25968 apache 25 0 398m 5612 528 R 46.6 0.1 0:42.73 httpd 4477 root 25 0 6084 396 280 R 46.3 0.0 0:59.53 dovecot 25982 root 25 0 397m 5108 240 R 45.9 0.1 0:18.01 httpd 25943 apache 25 0 2916 172 8 R 44.0 0.0 0:53.54 solver 30687 apache 25 0 468m 63m 1124 D 42.3 0.8 0:45.02 httpd 25978 apache 25 0 398m 5688 600 R 23.8 0.1 0:40.99 httpd 25983 root 25 0 397m 5272 384 D 14.9 0.1 0:18.99 httpd 935 root 10 -5 0 0 0 D 14.2 0.0 1:54.60 kjournald 25986 root 25 0 397m 5308 420 D 8.9 0.1 0:04.75 httpd 4011 haldaemo 25 0 31568 1476 716 S 5.6 0.0 0:24.36 hald 25956 apache 23 0 398m 5872 644 S 5.6 0.1 0:13.85 httpd 18336 root 18 0 13004 1332 724 R 0.3 0.0 1:46.66 top 1 root 18 0 10372 212 180 S 0.0 0.0 0:05.99 init 2 root RT -5 0 0 0 S 0.0 0.0 0:00.95 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 0:00.01 ksoftirqd/0 4 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 5 root RT -5 0 0 0 S 0.0 0.0 0:00.15 migration/1 6 root 34 19 0 0 0 S 0.0 0.0 0:00 .06 ksoftirqd/1 here is a normal top, when server is working fine: top - 01:50:41 up 21 min, 1 user, load average: 2.98, 2.70, 1.68 Tasks: 271 total, 2 running, 269 sleeping, 0 stopped, 0 zombie Cpu(s): 15.0%us, 1.1%sy, 0.0%ni, 81.4%id, 2.4%wa, 0.1%hi, 0.0%si, 0.0%st Mem: 8165600k total, 2035856k used, 6129744k free, 60840k buffers Swap: 2104496k total, 0k used, 2104496k free, 283744k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 2204 apache 17 0 466m 83m 19m S 25.9 1.0 0:22.16 httpd 11347 apache 15 0 466m 83m 19m S 25.9 1.0 0:26.10 httpd 18204 apache 18 0 481m 97m 19m D 25.2 1.2 0:13.99 httpd 4644 apache 18 0 481m 100m 19m D 24.6 1.3 1:17.12 httpd 4727 apache 17 0 481m 99m 19m S 24.3 1.2 1:10.77 httpd 4777 apache 17 0 482m 102m 21m S 23.6 1.3 1:38.27 httpd 8924 apache 15 0 483m 99m 19m S 22.3 1.3 1:13.41 httpd 9390 apache 18 0 483m 99m 19m S 18.9 1.2 1:05.35 httpd 4728 apache 16 0 481m 101m 19m S 14.3 1.3 1:12.50 httpd 4648 apache 15 0 481m 107m 27m S 12.6 1.4 1:18.62 httpd 24955 apache 15 0 467m 82m 19m S 3.3 1.0 0:21.80 httpd 4722 apache 15 0 503m 118m 19m R 1.7 1.5 1:17.79 httpd 4647 apache 15 0 484m 105m 20m S 1.3 1.3 1:40.73 httpd 4643 apache 16 0 481m 100m 20m S 0.7 1.3 1:11.80 httpd 1561 root 15 0 12900 1264 828 R 0.3 0.0 0:00.54 top 4434 mysql 15 0 496m 55m 4812 S 0.3 0.7 0:06.69 mysqld 4646 apache 15 0 481m 100m 19m S 0.3 1.3 1:25.51 httpd 1 root 18 0 10372 692 580 S 0.0 0.0 0:02.09 init 2 root RT -5 0 0 0 S 0.0 0.0 0:00.03 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/0 4 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/0 5 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/1 6 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/1 7 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/1 8 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/2 9 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/2 10 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/2 11 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/3 12 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/3 13 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/3 14 root RT -5 0 0 0 S 0.0 0.0 0:00.03 migration/4 15 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/4 16 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/4 17 root RT -5 0 0 0 S 0.0 0.0 0:00.02 migration/5 18 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/5 19 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/5 20 root RT -5 0 0 0 S 0.0 0.0 0:00.01 migration/6 21 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/6 22 root RT -5 0 0 0 S 0.0 0.0 0:00.00 watchdog/6 23 root RT -5 0 0 0 S 0.0 0.0 0:00.00 migration/7

• Why aren't there automated translators from one programming language to another?

  - by serg

  Most programming languages are Turing complete, which means that any task that can be solved in one language can be solved in another one, or even on Turing machine. Then why aren't there automatic translators that can convert programs from any given language to any other language? I've seen couple attempts for two languages, but they always work only on a limited subset of a language and can hardly be used for converting real projects. Is it possible, at least in theory, to write 100% correct translator between all languages? What are the challenges in practice? Are there any existing translators that work?

• C: What is a good source to teach standard/basic code conventions to someone newly learning the language ?

  - by shan23

  I'm tutoring someone who can be described as a rank newcomer in C. Understandably, she does not know much about coding conventions generally practiced, and hence all her programs tend to use single letter vars, mismatched spacing/indentation and the like, making it very difficult to read/debug her endeavors. My question is, is there a link/set of guidelines and examples which she can use for adopting basic code conventions ? It should not be too arcane as to scare her off, yet inclusive enough to have the basics covered (so that no one woulc wince looking at the code). Any suggestions ?

• Who does code coverage testing?

  - by Athiruban

  Recently, I was given an opportunity to increase the code coverage in a project based on Java Swing, MySQL and other technologies. They told me to bring the code coverage to 100%, while it was only 45% at the time I joined. I am just starting, not a professional developer, right from the beginning I felt bad even though I write and understand computer programs well. (The developed code contains a lot of technical stuff like Generics and no documentation about the code is available.) Has anyone experienced the same situation before? Please tell who is the right person to do the job.
