• Dual boot problem with ubuntu 12.04 and Vista

  - by vendella dahlahdoo

  Greetings from New Zealand. I have installed Microsoft Windows Vista and then installed Ubuntu 12.04 on my refurbished Compaq nx8220 laptop. I get the following infamous head hurting prompt continually. error: no such partition. grub rescue> Have tried most of the common recommended solutions. Live-CD then install Boot-Repair through the Terminal didn't work. It repaired all the linux stuff when restoring grub and then can't boot into Windows Vista. When I use Boot-Repair to fix the MBR, then I can't boot into Ubuntu. Tried installing BCD 2.1 in Vista and tried all the options one after another in BCD. Still no Ubuntu when selected through the options menu from BCD on restart/reboot. I have tried the boot repair option on the Ubuntu server CD-ROM, tried installing earlier versions of Ubuntu 11.04, 11.10, and Ubuntu server 11.10 and 12.04. Still the same result. I tried deleting the Ubuntu partitions through Vista a number of times and reinstalling Ubuntu. I have been trying and retrying all the options in Boot-Repair in different combinations for the past week and a half. I have tried at least 10 times installing and reinstalling Ubuntu. I really love Ubuntu and believe I have exhausted most of the recommended solutions and have spent too much time on this. Its driving me nuts!! please can someone help, I have finally given up (sigh). The following are some outputs from Boot-Repair from my last attempts. http://paste.ubuntu.com/1019227 http://paste.ubuntu.com/1019264 I was only allowed to post two links being a newbie. The only thing left for me to do is the flying Samoan dropkick laptop trick. Thanks in advance. Francis.

• Google Analytics custom variables and how are they recorded?

  - by mrtsherman

  I have been asked to add GA custom variable tracking to my company's website. The company website uses server side includes, so making modifications to the tracking code happens identically everywhere. Maintenance is therefore a headache. Also, GA takes about twenty-four hours for custom variables to start showing up in reports and that makes troubleshooting a headache. So if you have custom variables // visitor level tracking, id = 12345 _gaq.push(['_setCustomVar', 1, 'id', '12345', 1]); // page level tracking, email = you@me.com _gaq.push(['_setCustomVar', 1, 'email', 'you@me.com', 1]); The marketing people want the following out of this: User visits site and we record a unique id for them. Whenever they return this id will be used in GA. User signs up for our newsletter on page X and we record their email address. Whenever they return this email address is used in GA. Now a big problem for me is that I don't use GA and the marketing people don't use custom variables. So we don't actually know how this will work. Do I want Page, Session or Visitor level tracking? What happens because the same GA code is used on every page? If they visit the email sign up form and we record the email address, but then they go somewhere else where email is nonexistent will the value get 'overwritten.' Sorry for the long question, but there are a lot of unknowns for a GA noob.

• How can i compare Audio, what programming language should i use

  - by Pimmetje

  I have 2 audio files that are from almost the same source. But at some points there shifted a bit. Also the codecs does not match. I would like to make a program that takes a sample 2 - 4 seconds. And looks for it in the other file. (Most of the time it's not shifted more than 30 seconds). Than take the time and store it, Go ahead for a few seconds take a sample and find it again. This way i want to create a file where i can see on what points the file is shifted. For people who are more interested in what i want. I have a audio/video file speech and subtitles. But i have same speech from different sources with differs a bit in time. And i like to make a program that can correct the subtitle time for me. Enough about the problem I looked on the Internet for ways to compare audio files. Based on what i read comparing 2 audio files isn't that easy as i had hoped. Some talk about algorithms http://www.perlmonks.org/?node_id=169641 Some audio-library's portaudio.com aubio.org sourceforge.net/projects/ccaudio/ ambiera.com/irrklang/ The biggest problem i have is that i can't find something i can generate from the audio that i can use to compare with. I hope someone here can point me in the right direction.

• Introducing RedPatch

  - by timhill

  The Ksplice team is happy to announce the public availability of one of our git repositories, RedPatch. RedPatch contains the source for all of the changes Red Hat makes to their kernel, one commit per fix and we've published it on oss.oracle.com/git. With RedPatch, you can access the broken-out patches using git, browse them online via gitweb, and freely redistribute the source under the terms of the GPL. This is the same policy we provide for Oracle Linux and the Unbreakable Enterprise Kernel (UEK). Users can freely access the source, view the commit logs and easily identify the changes that are relevant to their environments. To understand why we've created this project we'll need a little history. In early 2011, Red Hat changed how they released their kernel source, going from a tarball that had individual patch files to shipping the kernel source as one giant tarball with a single patch for all Red Hat-introduced changes. For most people who work in the kernel this is merely an inconvenience; driver developers and other out-of-kernel module developers can see the end result to make sure their module still performs as expected. For Ksplice, we build individual updates for each change and rely on source patches that are broken-out, not a giant tarball. Otherwise, we wouldn’t be able to take the right patches to create individual updates for each fix, and to skip over the noise — like a change that speeds up bootup — which is unnecessary for an already-running system. We’ve been taking the monolithic Red Hat patch tarball and breaking it into smaller commits internally ever since they introduced this change. At Oracle, we feel everyone in the Linux community can benefit from the work we already do to get our jobs done, so now we’re sharing these broken-out patches publicly. In addition to RedPatch, the complete source code for Oracle Linux and the Oracle Unbreakable Enterprise Kernel (UEK) is available from both ULN and our public yum server, including all security errata. Check out RedPatch and subscribe to [email protected].com for discussion about the project. Also, drop us a line and let us know how you're using RedPatch!

• Update 3 for "NetBeans Platform for Beginners"

  - by Geertjan

  The latest monthly update of NetBeans Platform for Beginners was released during the last few days. Without any question at all, this book is awesome. I love how it is a 'living book' and that on a monthly basis new updates are made available. In this particular update, as before, reader comments and questions have led to changes and enhancements in the book. In addition, there's now a tighter integration between the long list of samples on GitHub and the book, since wherever a sample relates to a text in the book, the book has a handy icon, so that you know when to hop over to GitHub to get a related sample. Do you have comments or questions about the book? That's what the feedback link is for: https://leanpub.com/nbp4beginners/feedback And there's also a free sample, just in case you'd like to get a feel for the book prior to buying it: http://samples.leanpub.com/nbp4beginners-sample.pdf If you're from a company where you're all sharing a single copy of the book, it would be great if you'd go back and support this great project (and hopefully encourage future books being written) by buying additional copies, ideally one for each developer. Let's show the authors that writing books on the NetBeans Platform is a really profitable thing to do (and I'm hoping they'll write one on Maven and the NetBeans Platform, as well)!

• Audio not working in 12.10

  - by frampy

  I did a clean install of 12.10, when I open Sound Settings in gnome the only device in the list is "Dummy Output", and sound is not working. Sound worked fine out of the box in 12.04 I ran alsamixer, it says my card is "HDA Intel", and chip is "Realtek ALC880". The alsamixer playback output was set to mute at first, unmuting did not fix. I checked out the info at http://www.unixmen.com/2012003-howto-resolve-nosound-problem-on-ubuntu/ as suggested on a similar question, I've done everything there except installing the ubuntu audio dev team driver. Should I try install this? Edit: I've been reading the sound troubleshooting guide at https://help.ubuntu.com/community/SoundTroubleshooting It looks like Ubuntu is finding my audio device correctly. mike@wucade:~$ lspci -v | grep -A7 -i "audio" 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) Subsystem: Albatron Corp.

• How do I get dynamic subdomains on domain aliases in Plesk? [closed]

  - by mitchdesign

  I am running a site that is available via many domains. So all domains depend on the same code, but depending on the requested domain, the correct information is shown to the user. In Plesk, I have one domain set up and it has domain aliases for all the others. This works ok. Now, I'd like to be able to use subdomains on those aliased domains. Like the domains, the subdomains will be used as input for the system to display the correct information. So, they are not a fixed set. What I have done: - In DNS I have added *.example.com CNAME example.com to the main domain. This is automatically copied by Plesk to all the aliases. So DNS-wise, I think it's ok. - I have added a vhost.conf file to the main domain, containing ServerAlias *.maindomain.tld. This works for the main domain. But still, not for the aliased domains. And there is no place to put vhost.conf files for the aliased domains.. How do I tell the server to respond to those domain's subdomains as well?

• Website migration from WordPress to a static site and doing 301 redirects without access to existing site?

  - by user3114468

  Currently working on a project that is a hosted on WordPress that is being migrated to a static site. However I presently do not have access to the existing site as it's managed by another developer. The concern is not the lack of having access to content as the site owner has generated very little content (reason for migration) and we were able to do this manually. Rather the concern is to do 301 redirects. The site will not change domains but URLs such as from example.com/?page_id=3 to example.com/services. To add, the site is migrating to new server using same domain name. I thought maybe this could be done via editing permalinks prior to migration and WordPress would update automatically if configured to write on server. But if not configured (as this is not always the case) I do not have htaccess to fix it in case there are suddenly a bunch of 404 errors for every page. Really could use some help on the best procedure to follow in this case. This is the first migration project I've worked on.

  Google rolled out secured version of it’s search engine at https://google.com (did you notice https instead of http?). This search engine lets everyone to use Google search in a secured way. How is it secured? When you use https://google.com, the data exchanged between your browser and Google servers is encrypted to make sure that no one can sniff it. Is my search history secured from Google? No. The search queries you submit to Google are stored in Google servers. There is no change Google’s search history recording. Any differences between Regular Search and Secured Search Results? Yes. Secured search is slightly different from regular search. When you are accessing Google Secured Search Image search options will not be available on the left side bar. Site may respond slow compared to regular search site as there is a overhead to establish between your browser and the server.

• jQuery - upgrade from version 1.6.x to 1.7

  - by Renso

  Goal: Issues to consider when upgrading from jQuery version 1.6 to 1.7. This is a short list and may help identify the real issues you need to concern yourself with in stead of reading through all the release notesSummary of issues encountered during upgrade:As you prepare for upgrade to jQuery 1.7 from 1.6.x, this is a quick glimpse of all the issues that are relevant, not sure if it covers all but may be all you need to worry about.Use this method only for checking checkboxes and radio buttons:$("input:checked")http://api.jquery.com/checked-selector/This will work regardless of the version of jQuery you are using. Note that $("input).attr("checked") returns true prior to jQuery 1.6. Only retrieve "real" attributes with "attr", in order versions it would also retrieve properties like "tagName", this no longer works with jQuery 1.6.1+Why does $("input").attr("checked") no longer (from version 1.6.1+) return TRUE or FALSE, because if you look at the HTML (as well as W3C spec) it does not contain a true/false, but the value checked="checked", which is what it should have returned in the first place. $("input").prop("checked") works, return true, because there is in fact a DOM property for "checked" with the value being "true" or "false".Furthermore, if you want to upgrade to jQuery 1.7 you should only have to worry about this for most part:1. isNumeric() is new, be careful as the older version jQuery.isNaN() has been deprecated2. jqXHR success and error have been deprecated3. When rendering content with text(), white space issue cross-browsers: http://bugs.jquery.com/ticket/3144Other than the issues above I am not aware of any deprecations you need to worry about.Hope this helps to get everyone up to version 1.7

• How do I get my Intel HD graphics to work alongside my HD7850, as my second(HDMI out) monitor?

  - by AlexTes

  Title says it all. Further info: Motherboard: http://www.asrock.com/mb/Intel/Z77%20Pro3/ Processor: http://ark.intel.com/products/65520/Intel-Core-i5-3570K-Processor-%286M-Cache-up-to-3_80-GHz%29 So currently my main screen is running on my HD7850. Got drivers from the amd website. I have looked through dozens of questions here. I'm about to try booting Ubuntu from a stick and seeing if the xorg-edgers drivers might help. When booting, all action goes down on the very screen I'm trying to get to work.*EDIT never mind this. Seems to be special boot magic. As the screen only displays whiteline errors once the gui of ubuntu has kicked in and everything graphic is happening through my graphics card again. Connected through HDMI(motherboard)-DVI. So unless having multiple displays is a huge deal the solution hopefully isn't that complicated. I just feel I'm missing something simple. If this really is complicated, I should probably just hook up the display to my graphics card. My CPU is usually the one chilling out though so I'd like to try to get that to work. Also just because I don't want to buy an extra cable and this set up makes me feel warm and fuzzy inside. Tell me what to try or look up, I'll be most appreciative. Thank you! **UPDATE The x-swat ppa installed some intel stuff. Booting with one monitor plugged into the motherboard gives nothing. Doing it with the pc already on gives the purple "Ubuntu" with 5 dots boot/shutdown screen.

• Good resources for learning modern OpenGL (3.0 or later)?

  - by MatterGoal

  I stumble upon the search of a good resource to start with OpenGL (3.0 or later) . Well, I found a lot of books but none of them can be considered a good resource! Here two examples: OpenGL Programming Guide (7th edition) http://www.amazon.com/exec/obidos/ASIN/0321552628/khongrou-20 This is FULL of deprecated material! Almost every chapters begin with a note about that. OpenGL Superbible (5th Edition) http://www.amazon.com/exec/obidos/ASIN/0321712617/khongrou-20 This book uses a library created by the author to explain the main arguments, hiding what you want to learn! I don't want to learn how to use your library! I want to learn OpenGL! I hope that you understand this is not the same question like "hey I'm not able to use Google... tell me how to learn OpenGL". I've just finished a full and deep search but I can't find a good and complete resource to learn the "new" OpenGL avoiding deprecated topics. Can someone heading me in the right direction? I know C++ and I have 10 years of experience in development... where I can find a good resource?! I want to spend time on it and I want to learn deeply. (please feel free to edit my question, my English is terrible!)

• moving in the wrong direction

  - by Will

  Solution: To move a unit forward: forward = Quaternion(0,0,0,1) rotation.normalize() # ocassionally ... pos += ((rotation * forward) * rotation.conjugated()).xyz().normalized() * speed I think the trouble stemmed from how the Euclid math library was doing Quaternion*Vector3 multiplication, although I can't see it. I have a vec3 position, a quaternion for rotation and a speed. I compute the player position like this: rot *= Quaternion().rotate_euler(0.,roll_speed,pitch_speed) rot.normalize() pos += rot.conjugated() * Vector3(0.,0.,-speed) However, printing the pos to console, I can see that I only ever seem to travel on the x-axis. When I draw the scene using the rot quaternion to rotate my camera, it shows a proper orientation. What am I doing wrong? Here's an example: You start off with rotation being an identity quaternion: w=1,x=0,y=0,z=0 You move forward; the code correctly decrements the Z You then pitch right over to face the other way; if you spin only 175deg it'll go in right direction; you have to spin past 180deg. It doesn't matter which direction you spin in, up or down, though Your quaternion can then be something like: w=0.1,x=0.1,y=0,z=0 And moving forward, you actually move backward?! (I am using the euclid Python module, but its the same as every other conjulate) The code can be tried online at http://williame.github.com/ludum_dare_24_evolution/ The only key that adjusts the speed is W and S. The arrow keys only adjust the pitch/roll. At first you can fly ok, but after a bit of weaving around you end up getting sucked towards one of the sides. The code is https://github.com/williame/ludum_dare_24_evolution/blob/cbacf61a7159d2c83a2187af5f2015b2dde28687/tiny1web.py#L102

• Why won't Webmaster Tools let me set a preferred domain? (says to verify, but it should already be)

  - by Su'

  I've got a domain that I apparently forgot to set a preferred domain for, so I just tried to do it. Webmaster Tools instead popped up a little box: Part of the process of setting a preferred domain is to verify that you own http://www.example.com/. Please verify http://www.example.com/. I'm running into some problems following these instructions: As far as I can tell I already did verify sometime in the past. There's a TXT DNS record with the gibberish Google tells you to set for it that I couldn't have come up with myself. …and nothing is telling me this information is bad. So let's assume the site is somehow not actually verified. All the various methods' instructions start with "click the Manage Site button next to the site you want, and then click Verify this site." That button doesn't even exist on my screens. (It presumably goes away when you successfully verify?) Those instructions were all updated pretty recently, and the DNS one in particular just a couple weeks ago so it seems a bit unlikely they're inaccurate. I am not using Apps, and won't be, so can't try out the verification through there. Note that I also have another domain that I have not done any verification for which is showing the same behavior(no such button, being told to verify when it seems impossible etc.) so something appears to just be broken. I already have a no-www process in place server-side, so we can skip that. I'm just trying to get the box checked off in GWT. If I don't get any resolution, I'll eventually scrap the TXT record and see if the site gets un-verified(or whatever since it thinks it isn't), and see if I can just restart the process. It's not urgent so I'm just trying to figure out if I've gone blind to something or what. Did the button move?

• Redesigning my website has destroyed my SEO

  Unfortunately i read an article on how to avoid destroying your websites SEO from a redesign article AFTER its was too late! Here is the article (http://www.searchenginejournal.com/how-to-avoid-seo-disaster-during-a-website-redesign/42824/) On 20 November 12 completely redesigned our www.retromodern.com.au . We get ALL our customers from our website as we do not have a shop. Since that dreaded day a month ago the phone pretty much stopped, basically no emails, Google rankings down and Google analytics have halved by 50%. Yesterday i did some research into as as i had no idea that a re-design of a website could have such a damaging effect - yes i am a novice and use a WYSIWYG type web builder. There are lots of info on how to AVOID this from happening BUT what do i do as i have already made the mistake? Yesterday i reloaded my OLD site with my new pages in the background hoping this would be a start. I really have no idea of how to get out of this mess. Please please help. Thanks in Advance.

• Using Subdomains for Newly Regional Company

  - by Taylord22

  The company I work for is expanding their business to new territories. I've got a lot of stabilization to do in the region/state where we're one of the most well known companies of our kind. Currently, we have 3 distinct product lines which are currently distinguished by 3 separate URLS. This is affecting the user flow of our site, so we'd like to clean it up before launching our products into the various regions. The business has decided to grow into 5 new states (one state consisting of one county only) — none of which will feature all 3 products. Our homebase state is the only one that will have all 3 products this year. My initial thought was to use subdomains to separate out the regions, that way we could use a canonical tag to stabilize the root domain (which would feature home state content, and support content for all regions), and remove us from potential duplicate content penalization. Our product content will be nearly identical across the regions for the first year. I second guessed myself by thinking that it was perhaps better to use a "[product].root/region" URL instead. And I'm currently stuck by wondering if it was not better to build out subdomains for products and regions...using one modifier or the other as a funnel/branding page into the other. For instance, user lands on "region.root.com" and sees exactly what products we offer in that region. Basically, a tailored landing page. Meanwhile the bulk of the product content would actually live under "product.root.com/region/page". My head is spinning. And while searching for similar questions I also bumped into reference of another tag meant to be used in some similar cases to mine. I feel like there's a lot of risks involved in this subdomain strategy, but I also can't help but see the benefits in the user flow.

• ubuntu 12.10 grub doesn't appear efi mode

  - by user100604

  After a number of failed attempts on installing Ubuntu and Linux in the hybrid-gpt of Windows, in which I wanted different partitions by gparted, I ended up creating againg a conventional partitions table within the conventional system. This photo is not mine because as creating the partition I did not think in taking photos, but I am showing you it so that you can see the format “MS-DOS”, the standard format of gparted. My neetbook is a k55MV Asus 500GB (the page don't allow me to put 3 hiperlink I will put it at the end in a new coment 1) I installed Windows by creating a partition just for it. Windows created two partitions else for starting the system up. However creating it on ms-dos appear now in gpt view fotos 2) With the rest of the space, I created a 90-gigabyte partition for Ubuntu and the “swap” of 4 gb. The other partitions are for data. 3) I assured myself about installing Ubuntu in the partition whose format was ext4, for using that partition as base and to install the “grub” on the base of 500gb. I have boot the system up, Ubuntu is loaded but the grub does not appear. I have tried by pressing “beginning” “UPPER CASE LETTER”, but no way! I have checked the flies up, and partitions are there. http://www.subirimagenes.com/imagen-capturadepantalla-8080960.html By pressing fdisk-1, this picture comes up: http://www.subirimagenes.com/imagen-capturadepantalla-8080965.html I am spanish updated: at the beginning of the system, pressing f12 appears a grub without windows

• Should my web app have its own domain name?

  - by Daniero

  I'm going to get a domain name for my personal web page. It will contain my blog, photos and other personal stuff, plus different web apps and tools that I'm working on. I have put quite a lot of work in one of the web apps, and I think it has great potential. It covers a niche in a way that no other page has done before and I can see great possibilities to expand it. Via links to webstores and ads I think it could even make some money, and if I play it right this could be the place to go when you're into the specific niche that it covers (sorry for being so vague). My question is, would it be better for a (potentially great) web app like this to have its own domain name (nameofmyapp.com) instead of being a subpage of my personal page (mypersonaldomain.com/nameofmyapp)? Is the web app more likely to be found by others, via Google etc, with its own domain name? Could a "subpage" give more attention (visitors) to my personal page? pros and cons?

• Does (should?) changing the URI scheme name change the semantics?

  - by Doug

  If we take: http://example.com/foo is it fair to say that: ftp://example.com/foo .. points to the same resource, just using a different mechanism for resolving it (and of course possibly a different representation, but perhaps not)? This came to light in a discussion we were having surrounding some internal tooling with Git. We have to process some Git repositories, and they come to use as "git@{authority}/{path}" , however the library we're using to interface with them doesn't support the git protocol. I suggested that we should make the service robust in of that it tries to use HTTP or SSH, in essence, discovering what protocols/schemes are supported for resolving the repository at {path} under each {authority}. This was met with some criticism: "We don't know if that's the same repository". My response was: "It had better be!" Looking at RFC 3986, I see this excerpt: URI "resolution" is the process of determining an access mechanism and the appropriate parameters necessary to dereference a URI; this resolution may require several iterations. To use that access mechanism to perform an action on the URI's resource is to "dereference" the URI. Which makes me think that the resolution process is permitted to try different protocols, because: Although many URI schemes are named after protocols, this does not imply that use of these URIs will result in access to the resource via the named protocol. The only concern I have, I guess, is that I only see reference to the notion of changing protocols when it comes to traversing relationships: it is possible for a single set of hypertext documents to be simultaneously accessible and traversable via each of the "file", "http", and "ftp" schemes if the documents refer to each other with relative references. I'm inclined to think I'm wrong in my initial beliefs, because the Normalization and Comparison section of said RFC doesn't mention any way of treating two URIs as equivalent if they use different schemes. It seems like schemes named/based on IP protocols ought to have this notion, at least?

• Sprite batching seems slow

  - by Dekowta

  I have implemented a sprite batching system in OpenGL which will batch sprites based on their texture. How ever when I'm rendering ~5000 sprites all using the same texture i'm getting roughly 30fps. The process is as followed create sprite batch which also create a VBO with a set size and also creates the shaders as well call begin and initialise the render mode (at the moment just setting alpha on) call Draw with a sprite. This checks to see if the texture of the sprite has already been loaded and if so it just creates a pointer to the batch item and adds the new sprite coords. If not then it creates a new batch item and adds the sprite coords to that; it adds the batch item to the main batch. if the max sprite count is reached render will be called call end which calls render to render the left over sprites in the batch. and also resets the buffer offset render loops through each item in the batch and will bind the texture of the batch item, map the data to the buffer and then draw the array. the buffer will then be offset by the amount of sprites drawn. I have a feeling that it could be the method i'm using to store the batched sprites or it could be something else that i'm missing but I still can work it out. the cpp and h files are as followed http://pastebin.com/ZAytErGB http://pastebin.com/iCB608tA On top of this i'm also getting a weird issue where then two sprites are batched on after the other the second sprite will use the same coordinates as the last. And then when one if drawn after it is fine. I can't seem to find what is causing this issue. any help would be appreciated iv been sat trying to work this all out for a while now and cant seems to put my finger on what's causing it all.
