• ALSA Mutes Incorrect Audio Device on Headphone Event

  - by Gardiner

  I know what the problem is, I just don't know how to prevent it. When I plug in my headphones, ALSA automatically mutes (and sets the volume to 0) the 'Speaker' entry in alsamixer. If I go in and manually unmute (and turn the volume up) I have sound from my headphones. Question is, how do I change this behavior? I want it to adjust the volume to half, but not mute or set the volume to 0. I'm using Ubuntu Gnome 13.04 Output of amixer scontents Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined penum Playback channels: Mono Mono: Playback [on] This answer solved my issue: How can I get sound on headphones without switching back to 'Speakers' manually?

• After installing Ubuntu I can't boot Windows 8 anymore

  - by Gian Luca Scoccia

  I just bought a new laptop (a lenovo ideapad Z500) and it came installed with Windows 8. I wanted to have Ubuntu on it too, therefore I resized the Win8 partition from the control panel and installed Ubuntu on the free space I created. Ubuntu works perfectly, Windows does not load anymore... I tried the recommended repair with Boot-Repair but it did not fix, now I get a "Windows boot loader failed to start" on startup and then I get the GRUB screen. The partition summery created by Boot-Repair is here: http://paste.ubuntu.com/1444837/. How can I fix this? Thanks in advance for your help.

• Non-Embedded Content for your Popup Controls Target Container

  Yesterday I posted about client side predicates for Popup controls. Thanks for all the Tweets and Emails. The Popup control is very powerful and Popups are now an expected construct in many web user interfaces. I received a number of questions about using content in Popups that is not embedded in the containing page. Probably the easiest is to use in iFrame inside the Panel container for the Popup. In code it looks like this. Code Snippet <h1>Modal iFrame</h1> <asp:Button...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Can't get whole picture on the screen of a new monitor

  - by Gillian

  I have a 24inch, VM2453mh-LED, Viewsonic monitor using a Radeon 6570HD video card. Both are new. Viewsonic says the optimum size is 1920x1080. At this size the picture is beautiful, but it overlaps the screen vertically and horizontally. I am using Ubuntu 11.10, the Gnome 3 version, not Unity. On the Overview screen, the vertical icons are nearly off screen. Only the right edge shows. I opened the monitor's control menus to see if I could adjust it, but both the H/V Position and Horizontal Size are grayed out. I tried a 1600x1200 setting, and the picture was in bounds, but the quality was less, and it was stretched horizontally. The two monitor menu options were grayed out just like with the 1920x1080 setting. Can someone tell me how to resolve this problem?

• As a programmer what single discovery has given you the greatest boost in productivity?

  - by ChrisInCambo

  This question has been inspired by my recent discovery/adoption of distributed version control. I started using it (mercurial) just because I liked the idea of still being able to make commits at times when I couldn't connect to the central server. I never expected it would give me a large boost in general productivity, but a pleasant side effect I discovered was that making a new clone every time I started a new task and giving that clone a descriptive folder name is extremely effective at keeping me on task resulting is a noticeable productivity increase. So as a programmer what single discovery has given you the greatest boost in productivity? Extra respect for answers which involve tools or practices that aren't so obvious from the outside!

• Where does UBB store its settings?

  - by pjmorse

  We're moving a UBB forum from one host to another. (This is temporary; we're going to replace the forum eventually, but moving hosts has a higher priority.) We don't have a lot of experience with UBB, so we're feeling our way along in the dark. We got the UBB code installed on the new host, and we've done a dry-run database export from the original site to the new site. However, almost everything set in UBB's Control Panel section didn't come with the database export. If UBB doesn't store this data in the database, where is it stored? And if it is in the database, why would it not show up in a new forum when the database is imported? Did we somehow miss a table?

• Radeon HD5570 HDMI Video Card 5.1 Audio doesn't work

  - by ryandlf

  I am using Ubuntu and XMBC on my HTPC and have chosen the Radeon HD5570 Video card which has an HDMI output. In the sound preferences there is no surround sound option for the video card just stereo and although I can get sound through it in XBMC, my receiver does not state Dolby Digital on movies that are in fact Dolby so its definitely not giving me the true sound it should. Does this card not support surround sound through HDMI and I somehow missed it? If that is the case does anyone have suggestion that has been tested and works? Id like to know its going to work before investing in yet another video card. UPDATE I purchased a Nvidia GeForce GTS 450, plugged it in, downloaded the proprietary driver from the system control panel, disabled the onboard audio from the BIOS (not sure if this was necessary but I did it anyways), and changed the sound settings to use the new video card. Everything works flawlessly. It was a seemless setup.

• What Do I Need To Know About Servers In a Web Development Role?

  - by john

  I know that may sound a little vague, so I'll try and explain a little further... After being self employed developer for many years I'm now in search of a commercial web developer role. My only experience with servers and hosting is uploading through FTP and playing around with CPanel/WHM a little. The role's I'm going for are web development PHP, MySQL, HTML, CSS type roles, but in recent interviews I've been asked questions about setting up things on the server, that I had no idea what was being said... which wasn't ideal! Without knowing more than I do, it's hard to explain what exactly I'm looking to learn, but it's basically just the server elements I should know as a web developer? If you're a web developer, do you have any dealing with the server apart from uploading files, and if so, what? Are things like Subversion(SVN) and version control systems often set up by the web development team, could that be what they were talking about?

• What techniques can I use to render very large numbers of objects more efficiently in OpenGL?

  - by Luke

  You can think of my application as drawing a very large ball-and-stick diagram (or graph). At times, this graph can get very large, where the number of elements even outnumbers the pixels on the screen. Currently I am simply passing all of my textures (as GL_POINTS) and lines to the graphics card using VBO's. When the number of elements outnumbers the number of pixels, is this the most efficient way to do this? Or should I do some calculations on the CPU side before handing everything over to the GPU? If it matters, I do use GL_DEPTH_TEST and GL_ALPHA_TEST. I do some alpha blending, but probably not enough to make a huge performance difference. My scene can be static at times, but the user has control over a typical arc-ball camera and can pan, rotate, or zoom. It is during these operations that performance degradation is noticeable.

• How to use Google Analytics as an affiliate to track sales data

  - by lalex

  As an affiliate, how can we get more information on sales? It looks like the goals feature in GA is for those who have control over the receipt page. But we are sending users away using an affiliate link. With event tracking, we've been able to count the clicks and see which links are being clicked the most, but not which ones actually convert. We want to find out the following on each sale: Did the converted user come from search or internal traffic? If it was search, which keyword brought the user to our site (and clicked away and converted)? Is it possible?

• Constant noise in speakers and headphones

  - by user103978

  On my laptop, Samsung 300V5A-S19 I have the constant noise from the speakers. If I wear headphones, the sound becomes more pronounced (at half volume it mutes the music). The noise level is independent of the volume control. The noise disappears only when volume is completely muted. For the record, the sound is reminiscent of the noise of the waves or something like that. System information: Ubuntu 12.10, kernel 3.5.0-18 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) All packages in the system updated. PS: Following the advice from this message (click) yielded no result.

• Should I understand SVN before I jump to GIT?

  - by John Isaacks

  I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?

• Expandable or Auto-Resize TextBox Height

  Recently, I was asked to prepare a Facebook like expandable textbox in a ASP.NET web application, where user can input text and the textbox can be re-sized (more specifically the height) dynamically. I searched for a while and found quite a lot of solutions that use jQuery (example). However, I was looking for something more intrinsic and simple, and finally I found another script on a forum that just use few lines of JavaScript codes: 1.

• Moving dozens of existing standalone retail sites to one central inventory database: what should I know going in?

  - by palintropos

  This will be the first project of this scale that I have attempted, and the first time I have run a website at all (much less dozens) using an off-site database. In particular, I'd like to know: what sort of optimizations I should read up on to make this run as smoothly as possible? any pitfalls/gotchas wiser, more experienced folk are aware of I should be on the lookout for, and what damage-control and preventative measures I should take against the nightmare scenario of the main server (hosting the database) having an outage, grinding over 100 websites to a halt (because they have no access to the product data).

• Startup value for Win7

  - by Mike

  Problem at a glance: For Win 7, Ubuntu One changes the startup value to enabled whenever I run it More Details: If I change the startup value in: Control Panel System and Security Administrative Tools System Configuration Startup to disabled for Ubuntu One (since I don't want it to start when I log on), it succesfully stops Ubuntu One from starting at logon However, if I start the Ubuntu One manually, it changes the above startup value to enabled. Is there a way to prevent Ubuntu One from changing its startup value? I want it to stay disabled. I haven't found anything relevant in Ubuntu One's settings dialog.

• Mic not working on Lenovo G470

  - by Caveman

  I used a Lenovo G470 laptop (Core i5 2410M processor, AMD Radeon 6370M and 2GB DDR3 RAM) and I installed Ubuntu 12.04. I can't get the microphone to work. I encountered this type of issue before in my old Acer Aspire One with Ubuntu 10.04/10.10, and installing PulseAudio Volume Control and tweaking a little solves the problem. I tried the same solution to no avail in 12.04. I tried entering the alsa in terminal and my mic is not detected there. Does anybody encountered a similar problem? Any help will be greatly appreciated.

• Illuminated USB keyboard flickers

  - by Axj Member

  Does anyone know where I can download a driver for the VAKOSS TK-487-UK illuminated keyboard to run on Ubuntu? Or at least how to control the USB port so that it stops flickering on and off. The USB port works fine but the Keyboard is not recognized by Ubuntu... Already read the post on youtube and script but did not work either...tried changing USB ports, rebooting, etc. This has been going on for a week. The keyboard gets its power from the USB port. http://answers.yahoo.com/question/index?qid=20120128105854AAjgmgn

• Benefits of TOGAF or similar?

  - by Lunatik

  I can read the website blurb and be impressed by the alleged benefits, but I haven't worked anywhere or with anyone who followed the TOGAF (or any alternative) architecture framework. Our organisation has declared itself dedicated to moving from what is currently a fairly shambolic design & development model towards something approaching a modern structured process. Things like TOGAF have been mentioned as helping achieve a world-class enterprise development environment (!) but I'm convinced that no-one here really understands the real-world benefits that wholesale adoption might bring and, perhaps more importantly, the effort/pain required to achieve the same. Do you have experience in using TOGAF or similar to wrestle control in an organisation? Do you think that use of the framework brought any benefit? Edit: For clarification TOGAF is "The Open Group Architecture Framework", a detailed method and set of tools for developing an enterprise architecture. See: http://www.opengroup.org/architecture/togaf8-doc/arch/

• Moving from a traditional in memory Java session to persistent storage sessions

  - by Benju

  We have decided to take the plunge and move from using a typical java session provider in Tomcat/Jetty/etc to persisting everything to a central datastore. We are looking at using MongoDB for this. A few options come to mind... http://wiki.eclipse.org/Jetty/Tutorial/MongoDB_Session_Clustering This is nice because it will "auto-magically" persist our session to a Mongo installation. I am concerned however that we will not have fine grained control of what is happening. https://github.com/mattinsler/com.lowereast.guiceymongo/ GuiceMongo is interesting as it integrates with Guice. Perhaps we could persist everything via this ORM. Has anybody had to deal with this kind of move? It seems that moving from in memory to persistent session storage has a lot of gotchas.

• Consuming too much power on a Dell 15R

  - by Daniel Davis

  I'm new to Ubuntu, and I've just installed Ubuntu 11.10, and I must say I really like it a lot. I'm getting used to Ubuntu faster than I thought but the only issue I'm having is the power consumption. I have a " dell 15R with BIOS a07" and I uninstalled Ubuntu 11.04 because of some glitches I hated. None of those appear on this Ubuntu but now my computer discharges way too quick. when I check the power icon, it states that I have like 3:45 min remaining, which is fairly the same as what win7 and Ubuntu 11.04 used to tell me but 15 min later I check again and it gives me only 1:15 min remaining. Also, my computer seems to get a lot hotter than it used to. Is there more options to control the power usage on my laptop?

• What version will be chosen by MSXML2.XMLHTTP request, without version suffix? [migrated]

  - by jayarjo

  Probably every web developer is familiar with a pattern like this: var xmlHttp = null; if (window.XMLHttpRequest) { // If IE7, Mozilla, Safari, and so on: Use native object. xmlHttp = new XMLHttpRequest(); } else { if (window.ActiveXObject) { // ...otherwise, use the ActiveX control for IE5.x and IE6. xmlHttp = new ActiveXObject('MSXML2.XMLHTTP'); } } But the question is - if there are multiple MSXML versions available on the client's PC (let's say 3.0, 5.0, 6.0), which one of them will be chosen by MSXML2.XMLHTTP call (notice no version suffix at the end)? Will it be the latest or - not necessarily? And a side-question - is it possible to check which version was chosen?

• Site returning 404 header to google, not sure why

  - by Damon

  A Drupal site that works fine for regular users returns a 404 not found error when I try to use the W3C validator on it; it is also not being indexed by google at all (which is the main issue but I suspect there is a connection). It is a https:// site with .htaccess rule to redirect any http:// request to the https://. I had had it running in google webmaster tools and thought it was fine, but it turns out I had not added the https domain. After adding the https domain it's also returning the header as HTTP/1.1 404 Not Found Date: Mon, 15 Oct 2012 19:37:43 GMT Server: Apache Expires: Sun, 19 Nov 1978 05:00:00 GMT Cache-Control: no-cache, must-revalidate, post-check=0, pre-check=0 Robots.txt just has User-agent: * Crawl-delay: 10 # Files Disallow: /cron.php How can I check what the issue is here?

• Laptop wakes while lid is closed and overheats

  - by user56601

  I'm running 12.04 on a toshiba L305D with athlon x2 (Already suspect this has something to do with it). My laptop will wake from suspend, presumably from wireless scanning. This is a serious bug as sleeping laptops are often inside bags, so the cooling system is effectively disabled. I can no longer seriously use Ubuntu when I have to worry about hardware damage every time I close the lid. There is shockingly lack of information about anything close to this. So many control panels have been removed or dumbed down, and everyone seems to want this behavior instead of the opposite, for servers or torrents of whatever. Well, most laptop users will 99% be likely to regularly put their laptop in a backpack or briefcase or other bag. Does anyone know how to fix this?
